# Tech wishes for 2018

Post Syndicated from Eevee original https://eev.ee/blog/2018/02/18/tech-wishes-for-2018/

What would you like to see happen in tech in 2018?

(answer can be technical, social, political, combination, whatever)

Hmm.

## Less of this

I’m not really qualified to speak in depth about either of these things, but let me put my foot in my mouth anyway:

### The Blockchain™

Bitcoin was a neat idea. No, really! Decentralization is cool. Overhauling our terrible financial infrastructure is cool. Hash functions are cool.

Unfortunately, it seems to have devolved into mostly a get-rich-quick scheme for nerds, and by nearly any measure it’s turning into a spectacular catastrophe. Its “success” is measured in how much a bitcoin is worth in US dollars, which is pretty close to an admission from its own investors that its only value is in converting back to “real” money — all while that same “success” is making it less useful as a distinct currency.

Blah, blah, everyone already knows this.

What concerns me slightly more is the gold rush hype cycle, which is putting cryptocurrency and “blockchain” in the news and lending it all legitimacy. People have raked in millions of dollars on ICOs of novel coins I’ve never heard mentioned again. (Note: again, that value is measured in dollars.) Most likely, none of the investors will see any return whatsoever on that money. They can’t, really, unless a coin actually takes off as a currency, and that seems at odds with speculative investing since everyone either wants to hoard or ditch their coins. When the coins have no value themselves, the money can only come from other investors, and eventually the hype winds down and you run out of other investors.

I fear this will hurt a lot of people before it’s over, so I’d like for it to be over as soon as possible.

That said, the hype itself has gotten way out of hand too. First it was the obsession with “blockchain” like it’s a revolutionary technology, but hey, Git is a fucking blockchain. The novel part is the way it handles distributed consensus (which in Git is basically left for you to figure out), and that’s uniquely important to currency because you want to be pretty sure that money doesn’t get duplicated or lost when moved around.

But now we have startups trying to use blockchains for website backends and file storage and who knows what else? Why? What advantage does this have? When you say “blockchain”, I hear “single Git repository” — so when you say “email on the blockchain”, I have an aneurysm.

Bitcoin seems to have sparked imagination in large part because it’s decentralized, but I’d argue it’s actually a pretty bad example of a decentralized network, since people keep forking it. The ability to fork is a feature, sure, but the trouble here is that the Bitcoin family has no notion of federation — there is one canonical Bitcoin ledger and it has no notion of communication with any other. That’s what you want for currency, not necessarily other applications. (Bitcoin also incentivizes frivolous forking by giving the creator an initial pile of coins to keep and sell.)

And federation is much more interesting than decentralization! Federation gives us email and the web. Federation means I can set up my own instance with my own rules and still be able to meaningfully communicate with the rest of the network. Federation has some amount of tolerance for changes to the protocol, so such changes are more flexible and rely more heavily on consensus.

Federation is fantastic, and it feels like a massive tragedy that this rekindled interest in decentralization is mostly focused on peer-to-peer networks, which do little to address our current problems with centralized platforms.

And hey, you know what else is federated? Banks.

### AI

Again, the tech is cool and all, but the marketing hype is getting way out of hand.

Maybe what I really want from 2018 is less marketing?

For one, I’ve seen a huge uptick in uncritically referring to any software that creates or classifies creative work as “AI”. Can we… can we not. It’s not AI. Yes, yes, nerds, I don’t care about the hair-splitting about the nature of intelligence — you know that when we hear “AI” we think of a human-like self-aware intelligence. But we’re applying it to stuff like a weird dog generator. Or to whatever neural network a website threw into production this week.

And this is dangerously misleading — we already had massive tech companies scapegoating The Algorithm™ for the poor behavior of their software, and now we’re talking about those algorithms as though they were self-aware, untouchable, untameable, unknowable entities of pure chaos whose decisions we are arbitrarily bound to. Ancient, powerful gods who exist just outside human comprehension or law.

It’s weird to see this stuff appear in consumer products so quickly, too. It feels quick, anyway. The latest iPhone can unlock via facial recognition, right? I’m sure a lot of effort was put into ensuring that the same person’s face would always be recognized… but how confident are we that other faces won’t be recognized? I admit I don’t follow all this super closely, so I may be imagining a non-problem, but I do know that humans are remarkably bad at checking for negative cases.

Hell, take the recurring problem of major platforms like Twitter and YouTube classifying anything mentioning “bisexual” as pornographic — because the word is also used as a porn genre, and someone threw a list of porn terms into a filter without thinking too hard about it. That’s just a word list, a fairly simple thing that any human can review; but suddenly we’re confident in opaque networks of inferred details?

I don’t know. “Traditional” classification and generation are much more comforting, since they’re a set of fairly abstract rules that can be examined and followed. Machine learning, as I understand it, is less about rules and much more about pattern-matching; it’s built out of the fingerprints of the stuff it’s trained on. Surely that’s just begging for tons of edge cases. They’re practically made of edge cases.

I’m reminded of a point I saw made a few days ago on Twitter, something I’d never thought about but should have. TurnItIn is a service for universities that checks whether students’ papers match any others, in order to detect cheating. But this is a paid service, one that fundamentally hinges on its corpus: a large collection of existing student papers. So students pay money to attend school, where they’re required to let their work be given to a third-party company, which then profits off of it? What kind of a goofy business model is this?

And my thoughts turn to machine learning, which is fundamentally different from an algorithm you can simply copy from a paper, because it’s all about the training data. And to get good results, you need a lot of training data. Where is that all coming from? How many for-profit companies are setting a neural network loose on the web — on millions of people’s work — and then turning around and selling the result as a product?

This is really a question of how intellectual property works in the internet era, and it continues our proud decades-long tradition of just kinda doing whatever we want without thinking about it too much. Nothing if not consistent.

## More of this

A bit tougher, since computers are pretty alright now and everything continues to chug along. Maybe we should just quit while we’re ahead. There’s some real pie-in-the-sky stuff that would be nice, but it certainly won’t happen within a year, and may never happen except in some horrific Algorithmic™ form designed by people that don’t know anything about the problem space and only works 60% of the time but is treated as though it were bulletproof.

### Federation

The giants are getting more giant. Maybe too giant? Granted, it could be much worse than Google and Amazon — it could be Apple!

Amazon has its own delivery service and brick-and-mortar stores now, as well as providing the plumbing for vast amounts of the web. They’re not doing anything particularly outrageous, but they kind of loom.

Ad company Google just put ad blocking in its majority-share browser — albeit for the ambiguously-noble goal of only blocking obnoxious ads so that people will be less inclined to install a blanket ad blocker.

Twitter is kind of a nightmare but no one wants to leave. I keep trying to use Mastodon as well, but I always forget about it after a day, whoops.

Facebook sounds like a total nightmare but no one wants to leave that either, because normies don’t use anything else, which is itself direly concerning.

IRC is rapidly bleeding mindshare to Slack and Discord, both of which are far better at the things IRC sadly never tried to do and absolutely terrible at the exact things IRC excels at.

The problem is the same as ever: there’s no incentive to interoperate. There’s no fundamental technical reason why Twitter and Tumblr and MySpace and Facebook can’t intermingle their posts; they just don’t, because why would they bother? It’s extra work that makes it easier for people to not use your ecosystem.

I don’t know what can be done about that, except that hope for a really big player to decide to play nice out of the kindness of their heart. The really big federated success stories — say, the web — mostly won out because they came along first. At this point, how does a federated social network take over? I don’t know.

### Social progress

I… don’t really have a solid grasp on what’s happening in tech socially at the moment. I’ve drifted a bit away from the industry part, which is where that all tends to come up. I have the vague sense that things are improving, but that might just be because the Rust community is the one I hear the most about, and it puts a lot of effort into being inclusive and welcoming.

So… more projects should be like Rust? Do whatever Rust is doing? And not so much what Linus is doing.

### Open source funding

I haven’t heard this brought up much lately, but it would still be nice to see. The Bay Area runs on open source and is raking in zillions of dollars on its back; pump some of that cash back into the ecosystem, somehow.

I’ve seen a couple open source projects on Patreon, which is fantastic, but feels like a very small solution given how much money is flowing through the commercial tech industry.

One might wonder where the money to host a website comes from, then? I don’t know. Maybe we should loop this in with the above thing and find a more informal way to pay people for the stuff they make when we find it useful, without the financial and cognitive overhead of A Transaction or Giving Someone My Damn Credit Card Number. You know, something like Bitco— ah, fuck.

### Year of the Linux Desktop

I don’t know. What are we working on at the moment? Wayland? Do Wayland, I guess. Oh, and hi-DPI, which I hear sucks. And please fix my sound drivers so PulseAudio stops blaming them when it fucks up.

# Subtitle Heroes: Fansubbing Movie Criticized For Piracy Promotion

Post Syndicated from Andy original https://torrentfreak.com/subtitle-heroes-fansubbing-movie-criticized-for-piracy-promotion-180217/

With many thousands of movies and TV shows being made available illegally online every year, a significant number will be enjoyed by speakers of languages other than that presented in the original production.

When Hollywood blockbusters appear online, small armies of individuals around the world spring into action, translating the dialog into Chinese and Czech, Dutch and Danish, French and Farsi, Russian and Romanian, plus a dozen languages in between. TV shows, particularly those produced in the US, get the same immediate treatment.

For many years, subtitling (‘fansubbing’) communities have provided an incredible service to citizens around the globe, from those seeking to experience new culture and languages to the hard of hearing and profoundly deaf. Now, following in the footsteps of movies like TPB:AFK and Kim Dotcom: Caught in the Web, a new movie has premiered in Italy which celebrates this extraordinary movement.

Subs Heroes from writer and director Franco Dipietro hit cinemas at the end of January. It documents the contribution fansubbing has made to Italian culture in a country that under fascism in 1934 banned the use of foreign languages in films, books, newspapers and everyday speech.

The movie centers on the large subtitle site ItalianSubs.net. Founded by a group of teenagers in 2006, it is now run by a team of men and women who maintain their identities as regular citizens during the day but transform into “superheroes of fansubbing” at night.

Needless to say, not everyone is pleased with this depiction of the people behind the now-infamous 500,000 member site.

For many years, fansubbing attracted very little heat but over time anti-piracy groups have been turning up the pressure, accusing subtitling teams of fueling piracy. This notion is shared by local anti-piracy outfit FAPAV (Federation for the Protection of Audiovisual and Multimedia Content), which has accused Dipietro’s movie of glamorizing criminal activity.

In a statement following the release of Subs Heroes, FAPAV made its position crystal clear: sites like ItalianSubs do not contribute to the development of the audiovisual market in Italy.

“It is necessary to clarify: when a protected work is subtitled and there is no right to do so, a crime is committed,” the anti-piracy group says.

“[Italiansubs] translates and makes available subtitles of audiovisual works (films and television series) in many cases not yet distributed on the Italian market. All this without having requested the consent of the rights holders. Ergo the Italiansubs community is illegal.”

Italiansubs (note ad for movie, top right)

FAPAV General Secretary Federico Bagnoli Rossi says that the impact that fansubbers have on the market is significant, causing damage not only to companies distributing the content but also to those who invest in official translations.

The fact that fansubbers often translate content that is not yet available in the region only compounds matters, Rossi says, noting that unofficial translations can also have “direct consequences” on those who have language dubbing as an occupation.

“The audiovisual market today needs to be supported and the protection and fight against illicit behaviors are as fundamental as investments and creative ideas,” Rossi notes.

“Everyone must do their part, respecting the rules and with a competitive and global cultural vision. There are no ‘superheroes’ or noble goals behind piracy, but only great damage to the audiovisual sector and all its workers.”

Also piling on the criticism is the chief of the National Cinema Exhibitors’ Association, who wrote to all of the companies involved to remind them that unauthorized subtitling is a crime. According to local reports, there seems to be an underlying tone that people should avoid becoming associated with the movie.

This did not please director Franco Dipietro who is defending his right to document the fansubbing movement, whether the industry likes it or not.

“We invite those who perhaps think differently to deepen the discussion and maybe organize an event to talk about it together. The film is made to confront and talk about a phenomenon that, whether we like it or not, exists and we can not pretend that it is not there,” Dipietro concludes.

# This IoT Pet Monitor barks back

Post Syndicated from Alex Bate original https://www.raspberrypi.org/blog/iot-pet-monitor/

Jennifer Fox, founder of FoxBot Industries, uses a Raspberry Pi pet monitor to check the sound levels of her home while she is out, allowing her to keep track of when her dog Marley gets noisy or agitated, and to interact with the gorgeous furball accordingly.

#### Bark Back Project Demo

A quick overview and demo of the Bark Back, a project to monitor and interact with Check out the full tutorial here: https://learn.sparkfun.com/tutorials/bark-back-interactive-pet-monitor For any licensing requests please contact [email protected]

## Marley, bark!

Using a Raspberry Pi 3, speakers, SparkFun’s MEMS microphone breakout board, and an analogue-to-digital converter (ADC), the IoT Pet Monitor is fairly easy to recreate, all thanks to Jennifer’s full tutorial on the FoxBot website.

## Building the pet monitor

In a nutshell, once the Raspberry Pi and the appropriate bits and pieces are set up, you’ll need to sign up at CloudMQTT — it’s free if you select the Cute Cat account. CloudMQTT will create an invisible bridge between your home and wherever you are that isn’t home, so that you can check in on your pet monitor.

Within the project code, you’ll be able to calculate the peak-to-peak amplitude of sound the microphone picks up. Then you can decide how noisy is too noisy when it comes to the occasional whine and bark of your beloved pup.

The MEMS microphone breakout board collects sound data and relays it back to the Raspberry Pi via the ADC.

Next you can import sounds to a preset song list that will be played back when the volume rises above your predefined threshold. As Jennifer states in the tutorial, the sounds can easily be recorded via apps such as Garageband, or even on your mobile phone.

## Using the pet monitor

Whenever the Bark Back IoT Pet Monitor is triggered to play back audio, this information is fed to the CloudMQTT service, allowing you to see if anything is going on back home.

*incoherent coos of affection from Alex*

And as Jennifer recommends, a update of the project could include a camera or sensors to feed back more information about your home environment.

If you’ve created something similar, be sure to let us know in the comments. And if you haven’t, but you’re now planning to build your own IoT pet monitor, be sure to let us know in the comments. And if you don’t have a pet but just want to say hi…that’s right, be sure to let us know in the comments.

The post This IoT Pet Monitor barks back appeared first on Raspberry Pi.

# Court Orders Spanish ISPs to Block Pirate Sites For Hollywood

Post Syndicated from Andy original https://torrentfreak.com/court-orders-spanish-isps-to-block-pirate-sites-for-hollywood-180216/

Determined to reduce levels of piracy globally, Hollywood has become one of the main proponents of site-blocking on the planet. To date there have been multiple lawsuits in far-flung jurisdictions, with Europe one of the primary targets.

Following complaints from Disney, 20th Century Fox, Paramount, Sony, Universal and Warner, Spain has become one of the latest targets. According to the studios a pair of sites – HDFull.tv and Repelis.tv – infringe their copyrights on a grand scale and need to be slowed down by preventing users from accessing them.

HDFull is a platform that provides movies and TV shows in both Spanish and English. Almost 60% its traffic comes from Spain and after a huge surge in visitors last July, it’s now the 337th most popular site in the country according to Alexa. Visitors from Mexico, Argentina, United States and Chile make up the rest of its audience.

Repelis.tv is a similar streaming portal specializing in movies, mainly in Spanish. A third of the site’s visitors hail from Mexico with the remainder coming from Argentina, Columbia, Spain and Chile. In common with HDFull, Repelis has been building its visitor numbers quickly since 2017.

The studios demanding more blocks

With a ruling in hand from the European Court of Justice which determined that sites can be blocked on copyright infringement grounds, the studios asked the courts to issue an injunction against several local ISPs including Telefónica, Vodafone, Orange and Xfera. In an order handed down this week, Barcelona Commercial Court No. 6 sided with the studios and ordered the ISPs to begin blocking the sites.

“They damage the legitimate rights of those who own the films and series, which these pages illegally display and with which they profit illegally through the advertising revenues they generate,” a statement from the Spanish Federation of Cinematographic Distributors (FEDECINE) reads.

FEDECINE General director Estela Artacho said that changes in local law have helped to provide the studios with a new way to protect audiovisual content released in Spain.

“Thanks to the latest reform of the Civil Procedure Law, we have in this jurisdiction a new way to exercise different possibilities to protect our commercial film offering,” Artacho said.

“Those of us who are part of this industry work to make culture accessible and offer the best cinematographic experience in the best possible conditions, guaranteeing the continuity of the sector.”

The development was also welcomed by Stan McCoy, president of the Motion Picture Association’s EMEA division, which represents the plaintiffs in the case.

“We have just taken a welcome step which we consider crucial to face the problem of piracy in Spain,” McCoy said.

“These actions are necessary to maintain the sustainability of the creative community both in Spain and throughout Europe. We want to ensure that consumers enjoy the entertainment offer in a safe and secure environment.”

After gaining experience from blockades and subsequent circumvention in other regions, the studios seem better prepared to tackle fallout in Spain. In addition to blocking primary domains, the ruling handed down by the court this week also obliges ISPs to block any other domain, subdomain or IP address whose purpose is to facilitate access to the blocked platforms.

News of Spain’s ‘pirate’ blocks come on the heels of fresh developments in Germany, where this week a court ordered ISP Vodafone to block KinoX, one of the country’s most popular streaming portals.

# EFF Urges US Copyright Office To Reject Proactive ‘Piracy’ Filters

Post Syndicated from Andy original https://torrentfreak.com/eff-urges-us-copyright-office-to-reject-proactive-piracy-filters-180213/

Faced with millions of individuals consuming unlicensed audiovisual content from a variety of sources, entertainment industry groups have been seeking solutions closer to the roots of the problem.

As widespread site-blocking attempts to tackle ‘pirate’ sites in the background, greater attention has turned to legal platforms that host both licensed and unlicensed content.

Under current legislation, these sites and services can do business relatively comfortably due to the so-called safe harbor provisions of the US Digital Millennium Copyright Act (DMCA) and the European Union Copyright Directive (EUCD).

Both sets of legislation ensure that Internet platforms can avoid being held liable for the actions of others provided they themselves address infringement when they are made aware of specific problems. If a video hosting site has a copy of an unlicensed movie uploaded by a user, for example, it must be removed within a reasonable timeframe upon request from the copyright holder.

However, in both the US and EU there is mounting pressure to make it more difficult for online services to achieve ‘safe harbor’ protections.

Entertainment industry groups believe that platforms use the law to turn a blind eye to infringing content uploaded by users, content that is often monetized before being taken down. With this in mind, copyright holders on both sides of the Atlantic are pressing for more proactive regimes, ones that will see Internet platforms install filtering mechanisms to spot and discard infringing content before it can reach the public.

While such a system would be welcomed by rightsholders, Internet companies are fearful of a future in which they could be held more liable for the infringements of others. They’re supported by the EFF, who yesterday presented a petition to the US Copyright Office urging caution over potential changes to the DMCA.

“As Internet users, website owners, and online entrepreneurs, we urge you to preserve and strengthen the Digital Millennium Copyright Act safe harbors for Internet service providers,” the EFF writes.

“The DMCA safe harbors are key to keeping the Internet open to all. They allow anyone to launch a website, app, or other service without fear of crippling liability for copyright infringement by users.”

It is clear that pressure to introduce mandatory filtering is a concern to the EFF. Filters are blunt instruments that cannot fathom the intricacies of fair use and are liable to stifle free speech and stymie innovation, they argue.

“Major media and entertainment companies and their surrogates want Congress to replace today’s DMCA with a new law that would require websites and Internet services to use automated filtering to enforce copyrights.

“Systems like these, no matter how sophisticated, cannot accurately determine the copyright status of a work, nor whether a use is licensed, a fair use, or otherwise non-infringing. Simply put, automated filters censor lawful and important speech,” the EFF warns.

While its introduction was voluntary and doesn’t affect the company’s safe harbor protections, YouTube already has its own content filtering system in place.

ContentID is able to detect the nature of some content uploaded by users and give copyright holders a chance to remove or monetize it. The company says that the majority of copyright disputes are now handled by ContentID but the system is not perfect and mistakes are regularly flagged by users and mentioned in the media.

However, ContentID was also very expensive to implement so expecting smaller companies to deploy something similar on much more limited budgets could be a burden too far, the EFF warns.

“What’s more, even deeply flawed filters are prohibitively expensive for all but the largest Internet services. Requiring all websites to implement filtering would reinforce the market power wielded by today’s large Internet services and allow them to stifle competition. We urge you to preserve effective, usable DMCA safe harbors, and encourage Congress to do the same,” the EFF notes.

The same arguments, for and against, are currently raging in Europe where the EU Commission proposed mandatory upload filtering in 2016. Since then, opposition to the proposals has been fierce, with warnings of potential human rights breaches and conflicts with existing copyright law.

Back in the US, there are additional requirements for a provider to qualify for safe harbor, including having a named designated agent tasked with receiving copyright infringement notifications. This person’s name must be listed on a platform’s website and submitted to the US Copyright Office, which maintains a centralized online directory of designated agents’ contact information.

Under new rules, agents must be re-registered with the Copyright Office every three years, despite that not being a requirement under the DMCA. The EFF is concerned that by simply failing to re-register an agent, an otherwise responsible website could lose its safe harbor protections, even if the agent’s details have remained the same.

“We’re concerned that the new requirement will particularly disadvantage small and nonprofit websites. We ask you to reconsider this rule,” the EFF concludes.

The EFF’s letter to the Copyright Office can be found here.

# Give Your WordPress Blog a Voice With Our New Amazon Polly Plugin

Post Syndicated from Jeff Barr original https://aws.amazon.com/blogs/aws/give-your-wordpress-blog-a-voice-with-our-new-amazon-polly-plugin/

I first told you about Polly in late 2016 in my post Amazon Polly – Text to Speech in 47 Voices and 24 Languages. After that AWS re:Invent launch, we added support for Korean, five new voices, and made Polly available in all Regions in the aws partition. We also added whispering, speech marks, a timbre effect, and dynamic range compression.

New WordPress Plugin
Today we are launching a WordPress plugin that uses Polly to create high-quality audio versions of your blog posts. You can access the audio from within the post or in podcast form using a feature that we call Amazon Pollycast! Both options make your content more accessible and can help you to reach a wider audience. This plugin was a joint effort between the AWS team our friends at AWS Advanced Technology Partner WP Engine.

As you will see, the plugin is easy to install and configure. You can use it with installations of WordPress that you run on your own infrastructure or on AWS. Either way, you have access to all of Polly’s voices along with a wide variety of configuration options. The generated audio (an MP3 file for each post) can be stored alongside your WordPress content, or in Amazon Simple Storage Service (S3), with optional support for content distribution via Amazon CloudFront.

Installing the Plugin
I did not have an existing WordPress-powered blog, so I begin by launching a Lightsail instance using the WordPress 4.8.1 blueprint:

The plugin makes calls to AWS, and needs to have credentials in order to do so. I hop over to the IAM Console and created a new policy. The policy allows the plugin to access a carefully selected set of S3 and Polly functions (find the full policy in the README):

Then I create an IAM user (wp-polly-user). I enter the name and indicate that it will be used for Programmatic Access:

Then I attach the policy that I just created, and click on Review:

I review my settings (not shown) and then click on Create User. Then I copy the two values (Access Key ID and Secret Access Key) into a secure location. Possession of these keys allows the bearer to make calls to AWS so I take care not to leave them lying around.

Now I am ready to install the plugin! I go back to the WordPress Dashboard and click on Add New in the Plugins menu:

Then I click on Upload Plugin and locate the ZIP file that I downloaded from the WordPress Plugins site. After I find it I click on Install Now to proceed:

WordPress uploads and installs the plugin. Now I click on Activate Plugin to move ahead:

With the plugin installed, I click on Settings to set it up:

I enter my keys and click on Save Changes:

The General settings let me control the sample rate, voice, player position, the default setting for new posts, and the autoplay option. I can leave all of the settings as-is to get started:

The Cloud Storage settings let me store audio in S3 and to use CloudFront to distribute the audio:

The Amazon Pollycast settings give me control over the iTunes parameters that are included in the generated RSS feed:

Finally, the Bulk Update button lets me regenerate all of the audio files after I change any of the other settings:

With the plugin installed and configured, I can create a new post. As you can see, the plugin can be enabled and customized for each post:

I can see how much it will cost to convert to audio with a click:

When I click on Publish, the plugin breaks the text into multiple blocks on sentence boundaries, calls the Polly SynthesizeSpeech API for each block, and accumulates the resulting audio in a single MP3 file. The published blog post references the file using the <audio> tag. Here’s the post:

I can’t seem to use an <audio> tag in this post, but you can download and play the MP3 file yourself if you’d like.

The Pollycast feature generates an RSS file with links to an MP3 file for each post:

Pricing
The plugin will make calls to Amazon Polly each time the post is saved or updated. Pricing is based on the number of characters in the speech requests, as described on the Polly Pricing page. Also, the AWS Free Tier lets you process up to 5 million characters per month at no charge, for a period of one year that starts when you make your first call to Polly.

Going Further
The plugin is available on GitHub in source code form and we are looking forward to your pull requests! Here are a couple of ideas to get you started:

Voice Per Author – Allow selection of a distinct Polly voice for each author.

Quoted Text – For blogs that make frequent use of embedded quotes, use a distinct voice for the quotes.

Translation – Use Amazon Translate to translate the texts into another language, and then use Polly to generate audio in that language.

Other Blogging Engines – Build a similar plugin for your favorite blogging engine.

SSML Support – Figure out an interesting way to use Polly’s SSML tags to add additional character to the audio.

Let me know what you come up with!

# Schaller: An update on Pipewire – the multimedia revolution

Post Syndicated from corbet original https://lwn.net/Articles/745943/rss

Christian Schaller provides
us with an update
on the state of the new PipeWire multimedia system.
So as you probably noticed one thing we didn’t mention above is how
to deal with PulseAudio applications. Handling this usecase is still on the
todo list and the plan is to at least initially just keep PulseAudio
running on the system outputting its sound through PipeWire. That said we
are a bit unsure how many applications would actually be using this path
because as mentioned above all GStreamer applications for instance would be
PipeWire native automatically through the PipeWire GStreamer
plugins.

# Court Orders Tickbox to Keep Pirate Streaming Addons Out

Post Syndicated from Ernesto original https://torrentfreak.com/court-orders-tickbox-to-keep-pirate-streaming-addons-out-180131/

Kodi-powered set-top boxes are a great way to to stream video content to a TV, but sellers who ship these devices with unauthorized add-ons give them a bad reputation.

According to the Alliance for Creativity and Entertainment (ACE), an anti-piracy partnership comprised of Hollywood studios, Netflix, Amazon, and more than two dozen other companies, Tickbox TV is one of these bad actors.

Last year, ACE filed a lawsuit against the Georgia-based company, which sells Kodi-powered set-top boxes that stream a variety of popular media.

According to ACE, these devices are nothing more than pirate tools, allowing buyers to stream copyright-infringing content and being advertised as such. The coalition, therefore, asked the court for an injunction to prevent Tickbox from facilitating copyright infringement by removing all pirate add-ons from previously sold devices.

This week US District Court Judge Michael Fitzgerald issued a preliminary injunction, which largely sides with the movie companies. According to the Judge, there is sufficient reason to believe that Tickbox can be held liable for inducing copyright infringement.

One of the claims is that Tickbox promoted its service for piracy purposes, and according to the Judge the movie companies provided enough evidence to make this likely. This includes various advertising messages the box seller used.

“There is ample evidence that, at least prior to Plaintiffs’commencement of this action, TickBox explicitly advertised the Device as a means to accessing unauthorized versions of copyrighted audiovisual content,” Judge Fitzgerald writes.

In its defense, Tickbox argued that it merely offered a computer which users can then configure to their liking. However, the Judge points out that the company went further, as it actively directed its users to install certain themes (builds) to watch movies, TV and sports.

“Thus, the fact that the Device is just a ‘computer’ that can be used for infringing and noninfringing purposes does not insulate TickBox from liability if [..] the Device is actually used for infringing purposes and TickBox encourages such use.”

Taking these and several other factors into account, the Court ruled that a preliminary injunction is warranted at this stage. After the lawsuit was filed, Tickbox already voluntarily removed much of the inducing advertisements and addons, and this will remain so.

The preliminary injunction compels TickBox to the current version of the user interface, without easy access to pirate add-ons. The devices should no longer contain links to any of the themes and addons that the movie companies have flagged as copyright infringing.

Tickbox had argued that a broad injunction could shut down its business, but the court counters this. Customers will still be able to use the box for legitimate purposes. If they are no longer interested it suggests that piracy was the main draw.

“[A]n injunction of this scope will not ‘shut down Defendant’s business’ as TickBox contends. In the event that such an injunction does shut TickBox down, that will be indicative not of an unjustifiably burdensome injunction, but of a nonviable business model,” Judge Fitzgerald writes.

The preliminary injunction is not final yet as there are several questions still unanswered.

It’s unclear, for example, if and how Tickbox should remove addons from previously sold devices. The Court, therefore, instructs both parties to attempt to reach agreement on these outstanding issues, to include them in an updated injunction.

The above findings are preliminary and apply specifically to the injunction request and the case itself will continue. However, the Court’s early opinion suggests that Tickbox has plenty of work ahead to prove its innocence.

A copy of the preliminary injunction is available here (pdf), and Judge Fitzgerald’s findings can be found here (pdf).

# Huge Rightsholder Coalition Calls on New EU Presidency to Remove Safe Harbors

While piracy of all kinds is often viewed as a threat to the creative industries, a new type of unauthorized content distribution has been gaining prominence over the past few years.

Sites like YouTube, that allow their users to upload all kinds of material – some of it infringing – are now seen as undermining a broad range of industries that rely on both video and audio to generate revenue.

The cries against such User Uploaded Content (UUC) sites are often led by the music industry, which complains that the safe harbor provisions of copyright law are being abused while UUC sites generate review from infringing content. In tandem, while that free content is made available, UUC sites have little or no incentive to pay for official content licenses, and certainly not at a rate considered fair by the industry.

This mismatch, between the price that content industries would like to achieve for licenses and what they actually achieve, is now known as the ‘Value Gap’.

Today, in advance of an EU meeting on the draft Copyright Directive, a huge coalition of rightsholder groups is calling on the new EU Presidency not to pass up an “unmissable opportunity” to find a solution to their problems.

In a letter addressed to the Presidency of the Council of the European Union, which Bulgaria officially took over January 1, 2018, an army of rightsholders lay out their demands.

“We represent musical, audio-visual, literary, visual authors; performers; book, press, musical, scientific, technical and medical publishers; recorded music, film and TV producers; football leagues; broadcasters; distributors and photo agencies. These are at the very heart of Europe’s creative sector,” the groups write.

“We have formed an alliance to campaign for a solution to a major problem which is holding back our sector and jeopardizing future sustainability – the Transfer of Value, otherwise known as the Value Gap.

“User uploaded content services have become vast distributors of our creative works e.g. film, music, photos, broadcasts, text and sport content – all while refusing to negotiate fair or any copyright licences with us as right holders.”

Value Gap Coalition

Featuring groups representing many thousands of rightsholders, the coalition is the broadest yet to call for action against the ‘Value Gap’. Or, to put it another way, to demand a change in the law to prevent sites like YouTube, Facebook and other hosting platforms from “hiding” behind provisions designed to protect them from the infringing activities of others.

“This problem is caused by a lack of clarity surrounding the application of copyright to certain online services and the abuse of European copyright ‘safe harbor’ rules in the e-Commerce Directive (2000/31/EC) by those services,” the coalition writes.

Referencing the EU Copyright Directive proposal tabled by the European Commission in September 2016, the coalition says that UUC services communicating content to the public should be compelled to obtain licenses for that content. If they play an “active role” through promotion or optimization of content, UUC platforms should be denied ‘safe harbors’ under copyright law, they argue.

Noting that there is “no solution” to the problem without the above fixes, the coalition cites last year’s ruling by the Court of Justice of the European Union which found that The Pirate Bay knowingly provide users with a platform to share copyright-infringing links.

“It is important to recall that the underlying policy objective of this legislation is to address the current unfairness in the online market due to the misapplication of copyright liability rules by UUC services. We would therefore like to stress that the focus should remain on finding effective solutions to tackle this issue.

“As an alliance, we look forward to working with your Presidency to achieve an effective solution to the Value Gap problem for the benefit of Europe,” the coalition concludes.

The letter, addressed to Prime Minister Borissov, Minister Pavlova and Minister Banov, arrives in the wake of an alert sounded by several Members of the European Parliament.

Earlier this month they warned that the EU’s proposed mandatory upload filters – which could see UUC sites pre-screen user-uploaded content for infringement – amount to “censorship machines” that will do more harm than good.

# Denuvo Has Been Sold to Global Anti-Piracy Outfit Irdeto

Post Syndicated from Andy original https://torrentfreak.com/denuvo-has-been-sold-to-global-anti-piracy-outfit-irdeto-180123/

It’s fair to say that of all video games anti-piracy technologies, Denuvo is perhaps the most hated of recent times. That hatred unsurprisingly stems from both its success and complexity.

Those with knowledge of the system say it’s fiendishly difficult to defeat but in recent times, cracks have been showing. In 2017, various iterations of the anti-tamper system were defeated by several cracking groups, much to the delight of the pirate masses.

Now, however, a new development has the potential to herald a new lease of life for the Austria-based anti-piracy company. A few moments ago it was revealed that the company has been bought by Irdeto, a global anti-piracy company with considerable heritage and resources.

“Irdeto has acquired Denuvo, the world leader in gaming security, to provide anti-piracy and anti-cheat solutions for games on desktop, mobile, console and VR devices,” Irdeto said in a statement.

“Denuvo provides technology and services for game publishers and platforms, independent software vendors, e-publishers and video publishers across the globe. Current Denuvo customers include Electronic Arts, UbiSoft, Warner Bros and Lionsgate Entertainment, with protection provided for games such as Star Wars Battlefront II, Football Manager, Injustice 2 and others.”

Irdeto says that Denuvo will “continue to operate as usual” with all of its staff retained – a total of 45 across Austria, Poland, the Czech Republic, and the US. Denuvo headquarters in Salzburg, Austria, will also remain intact along with its sales operations.

“The success of any game title is dependent upon the ability of the title to operate as the publisher intended,” says Irdeto CEO Doug Lowther.

“As a result, protection of both the game itself and the gaming experience for end users is critical. Our partnership brings together decades of security expertise under one roof to better address new and evolving security threats. We are looking forward to collaborating as a team on a number of initiatives to improve our core technology and services to better serve our customers.”

Denuvo was founded relatively recently in 2013 and employs less than 50 people. In contrast, Irdeto’s roots go all the way back to 1969 and currently has almost 1,000 staff. It’s a subsidiary of South Africa-based Internet and media group Naspers, a corporate giant with dozens of notable companies under its control.

While Denuvo is perhaps best known for its anti-piracy technology, Irdeto is also placing emphasis on the company’s ability to hinder cheating in online multi-player gaming environments. This has become a hot topic recently, with several lawsuits filed in the US by companies including Blizzard and Epic.

Denuvo CEO Reinhard Blaukovitsch

“Hackers and cybercriminals in the gaming space are savvy, and always have been. It is critical to implement robust security strategies to combat the latest gaming threats and protect the investment in games. Much like the movie industry, it’s the only way to ensure that great games continue to get made,” says Denuvo CEO Reinhard Blaukovitsch.

“In joining with Irdeto, we are bringing together a unique combination of security expertise, technology and enhanced piracy services to aggressively address security challenges that customers and gamers face from hackers.”

While it seems likely that the companies have been in negotiations for some, the timing of this announcement also coincides with negative news for Denuvo.

Yesterday it was revealed that the latest variant of its anti-tamper technology – Denuvo v4.8 – had been defeated by online cracking group CPY (Conspiracy). Version 4.8 had been protecting Sonic Forces since its release early November 2017 but the game was leaked out onto the Internet late Sunday with all protection neutralized.

Sonic Forces cracked by CPY

Irdeto has a long history of acquiring anti-piracy companies and technologies. They include Lockstream (DRM for content on mobile phones), Philips Cryptoworks (DVB conditional access system), Cloakware (various security), Entriq (media protection), BD+ (Blu-ray protection), and BayTSP (anti-piracy monitoring).

It’s also noteworthy that Irdeto supplied behind-the-scenes support in two of the largest IPTV provider raids of recent times, one focused on Spain in 2017 and more recently in Cyprus, Bulgaria, Greece and the Netherlands (1,2,3).

# Dark Caracal: Global Espionage Malware from Lebanon

Post Syndicated from Bruce Schneier original https://www.schneier.com/blog/archives/2018/01/dark_caracal_gl.html

The EFF and Lookout are reporting on a new piece of spyware operating out of Lebanon. It primarily targets mobile devices compromised by fake secure messaging clients like Signal and WhatsApp.

From the Lookout announcement:

Dark Caracal has operated a series of multi-platform campaigns starting from at least January 2012, according to our research. The campaigns span across 21+ countries and thousands of victims. Types of data stolen include documents, call records, audio recordings, secure messaging client content, contact information, text messages, photos, and account data. We believe this actor is operating their campaigns from a building belonging to the Lebanese General Security Directorate (GDGS) in Beirut.

It looks like a complex infrastructure that’s been well-developed, and continually upgraded and maintained. It appears that a cyberweapons arms manufacturer is selling this tool to different countries. From the full report:

Dark Caracal is using the same infrastructure as was previously seen in the Operation Manul campaign, which targeted journalists, lawyers, and dissidents critical of the government of Kazakhstan.

There’s a lot in the full report. It’s worth reading.

# Hollywood Asks New UK Culture Secretary To Fight Online Piracy

Post Syndicated from Andy original https://torrentfreak.com/hollywood-asks-new-uk-culture-secretary-to-fight-online-piracy-180119/

Following Prime Minister Theresa May’s cabinet reshuffle earlier this month, Matt Hancock replaced Karen Bradley as Secretary of State for Digital, Culture, Media and Sport.

Hancock, the 39-year-old MP for West Suffolk, was promoted from his role as Minister for Digital and Culture, a position he’d held since July 2016.

“Thrilled to become DCMS Secretary. Such an exciting agenda, so much to do, and great people. Can’t wait to get stuck in,” he tweeted.

Of course, the influence held by the Culture Secretary means that the entertainment industries will soon come calling, seeking help and support in a number of vital areas. No surprise then that Stan McCoy, president and managing director at the ‎Motion Picture Association’s EMEA division, has just jumped in with some advice for Hancock.

In an open letter published on Screen Daily, McCoy begins by reminding Hancock that the movie industry contributes considerable sums to the UK economy.

“We are one of the country’s most valuable economic and cultural assets – worth almost £92bn, growing at twice the rate of the economy, and making a positive contribution to the UK’s balance of payments,” McCoy writes.

“Britain’s status as a center of excellence for the audiovisual sector in particular is no accident: It results from the hard work and genius of our creative workforce, complemented by the support of governments that have guided their policies toward enabling continued excellence and growth.”

McCoy goes on to put anti-piracy initiatives at the very top of his wishlist – and Hancock’s to-do list.

“A joined-up strategy to curb proliferation of illegal, often age-inappropriate and malware-laden content online must include addressing the websites, environments and apps that host and facilitate piracy,” McCoy says.

“In addition to hurting one of Britain’s most important industries, they are overwhelmingly likely to harm children and adult consumers through nasty ads, links to adult content with no age verification, scams, fraud and other unpleasantness.”

That McCoy begins with the “piracy is dangerous” approach is definitely not a surprise. This Hollywood and wider video industry strategy is now an open secret. However, it feels a little off that the UK is being asked to further tackle pirate sites.

Through earlier actions, facilitated by the UK legal system and largely sympathetic judges, many thousands of URLs and domains linking to pirate sites, mirrors and proxies, are impossible to access directly through the UK’s major ISPs. Although a few slip through the net, directly accessing the majority of pirate sites in the UK is now impossible.

That’s already a considerable overseas anti-piracy position for the MPA who, as the “international voice” of the Motion Picture Association of America (MPAA), represents American corporations including Disney, Paramount, Sony Pictures, 20th Century Fox, Universal, and Warner Bros.

There’s no comparable blocking system for these companies to use in the United States and rightsholders in the UK can even have extra sites blocked without going back to court for permission. In summary, these US companies arguably get a better anti-piracy deal in the UK than they do at home in the United States.

In his next point, McCoy references last year’s deal – which was reached following considerable pressure from the UK government – between rightsholders and search engines including Google and Bing to demote ‘pirate’ results.

“Building on last year’s voluntary deal with search engines, the Government should stay at the cutting edge of ensuring that everyone in the ecosystem – including search engines, platforms and social media companies – takes a fair share of responsibility,” McCoy says.

While this progress is clearly appreciated by the MPA/MPAA, it’s difficult to ignore that the voluntary arrangement to demote infringing content is somewhat special if not entirely unique. There is definitely nothing comparable in the United States so keeping up the pressure on the UK Government feels a little like getting the good kid in class to behave, while his rowdy peers nearer the chalkboard get ignored.

The same is true for McCoy’s call for the UK to “banish dodgy streaming devices”.

“Illegal streaming devices loaded with piracy apps and malware – not to mention the occasional electrical failure – are proliferating across the UK, to the detriment of consumers and industry,” he writes.

“The sector is still waiting for the Intellectual Property Office to publish the report on its Call for Views on this subject. This will be one of several opportunities, along with the promised Digital Charter, to make clear that these devices and the apps and content they supply are unacceptable, dangerous to consumers, and harmful to the creative industry.”

Again, prompting the UK to stay on top of this game doesn’t feel entirely warranted.

With dozens of actions over the past few years, the Police Intellectual Property Crime Unit and the Federation Against Copyright Theft (which Hollywood ironically dumped in 2016) have done more to tackle the pirate set-top box problem than any group on the other side of the Atlantic.

Admittedly the MPAA is now trying to catch up, with recent prosecutions of two ‘pirate’ box vendors (1,2), but largely the work by the studios on their home turf has been outpaced by that of their counterparts in the UK.

Maybe Hancock will mention that to Hollywood at some point in the future.

# Privacy expectations and the connected home

Post Syndicated from Matthew Garrett original https://mjg59.dreamwidth.org/50229.html

Traditionally, devices that were tied to logins tended to indicate that in some way – turn on someone’s xbox and it’ll show you their account name, run Netflix and it’ll ask which profile you want to use. The increasing prevalence of smart devices in the home changes that, in ways that may not be immediately obvious to the majority of people. You can configure a Philips Hue with wall-mounted dimmers, meaning that someone unfamiliar with the system may not recognise that it’s a smart lighting system at all. Without any actively malicious intent, you end up with a situation where the account holder is able to infer whether someone is home without that person necessarily having any idea that that’s possible. A visitor who uses an Amazon Echo is not necessarily going to know that it’s tied to somebody’s Amazon account, and even if they do they may not know that the log (and recorded audio!) of all interactions is available to the account holder. And someone grabbing an egg out of your fridge is almost certainly not going to think that your smart egg tray will trigger an immediate notification on the account owner’s phone that they need to buy new eggs.

Things get even more complicated when there’s multiple account support. Google Home supports multiple users on a single device, using voice recognition to determine which queries should be associated with which account. But the account that was used to initially configure the device remains as the fallback, with unrecognised voices ended up being logged to it. If a voice is misidentified, the query may end up being logged to an unexpected account.

There’s some interesting questions about consent and expectations of privacy here. If someone sets up a smart device in their home then at some point they’ll agree to the manufacturer’s privacy policy. But if someone else makes use of the system (by pressing a lightswitch, making a spoken query or, uh, picking up an egg), have they consented? Who has the social obligation to explain to them that the information they’re producing may be stored elsewhere and visible to someone else? If I use an Echo in a hotel room, who has access to the Amazon account it’s associated with? How do you explain to a teenager that there’s a chance that when they asked their Home for contact details for an abortion clinic, it ended up in their parent’s activity log? Who’s going to be the first person divorced for claiming that they were vegan but having been the only person home when an egg was taken out of the fridge?

To be clear, I’m not arguing against the design choices involved in the implementation of these devices. In many cases it’s hard to see how the desired functionality could be implemented without this sort of issue arising. But we’re gradually shifting to a place where the data we generate is not only available to corporations who probably don’t care about us as individuals, it’s also becoming available to people who own the more private spaces we inhabit. We have social norms against bugging our houseguests, but we have no social norms that require us to explain to them that there’ll be a record of every light that they turn on or off. This feels like it’s going to end badly.

# ISP: We’re Cooperating With Police Following Pirate IPTV Raid

Post Syndicated from Andy original https://torrentfreak.com/isp-were-cooperating-with-police-following-pirate-iptv-raid-180113/

This week, police forces around Europe took action against what is believed to be one of the world’s largest pirate IPTV networks.

The investigation, launched a year ago and coordinated by Europol, came to head on Tuesday when police carried out raids in Cyprus, Bulgaria, Greece, and the Netherlands. A fresh announcement from the crime-fighting group reveals the scale of the operation.

It was led by the Cypriot Police – Intellectual Property Crime Unit, with the support of the Cybercrime Division of the Greek Police, the Dutch Fiscal Investigative and Intelligence Service (FIOD), the Cybercrime Unit of the Bulgarian Police, Europol’s Intellectual Property Crime Coordinated Coalition (IPC³), and supported by members of the Audiovisual Anti-Piracy Alliance (AAPA).

In Cyprus, Bulgaria and Greece, 17 house searches were carried out. Three individuals aged 43, 44, and 53 were arrested in Cyprus and one was arrested in Bulgaria.

All stand accused of being involved in an international operation to illegally broadcast around 1,200 channels of pirated content to an estimated 500,000 subscribers. Some of the channels offered were illegally sourced from Sky UK, Bein Sports, Sky Italia, and Sky DE. On Thursday, the three individuals in Cyprus were remanded in custody for seven days.

“The servers used to distribute the channels were shut down, and IP addresses hosted by a Dutch company were also deactivated thanks to the cooperation of the authorities of The Netherlands,” Europol reports.

“In Bulgaria, 84 servers and 70 satellite receivers were seized, with decoders, computers and accounting documents.”

TorrentFreak was previously able to establish that Megabyte-Internet Ltd, an ISP located in the small Bulgarian town Petrich, was targeted by police. The provider went down on Tuesday but returned towards the end of the week. Responding to our earlier inquiries, the company told us more about the situation.

“We are an ISP provider located in Petrich, Bulgaria. We are selling services to around 1,500 end-clients in the Petrich area and surrounding villages,” a spokesperson explained.

“Another part of our business is internet services like dedicated unmanaged servers, hosting, email servers, storage services, and VPNs etc.”

The spokesperson added that some of Megabyte’s equipment is located at Telepoint, Bulgaria’s biggest datacenter, with connectivity to Petrich. During the raid the police seized the company’s hardware to check for evidence of illegal activity.

“We were informed by the police that some of our clients in Petrich and Sofia were using our service for illegal streaming and actions,” the company said.

“Of course, we were not able to know this because our services are unmanaged and root access [to servers] is given to our clients. For this reason any client and anyone that uses our services are responsible for their own actions.”

TorrentFreak asked many more questions, including how many police attended, what type and volume of hardware was seized, and whether anyone was arrested or taken for questioning. But, apart from noting that the police were friendly, the company declined to give us any additional information, revealing that it was not permitted to do so at this stage.

What is clear, however, is that Megabyte-Internet is offering its full cooperation to the authorities. The company says that it cannot be held responsible for the actions of its clients so their details will be handed over as part of the investigation.

“So now we will give to the police any details about these clients because we hold their full details by law. [The police] will find [out about] all the illegal actions from them,” the company concludes, adding that it’s fully operational once more and working with clients.

# MusE 3.0.0 released

Post Syndicated from ris original https://lwn.net/Articles/743598/rss

Three years after the last stable release, version 3.0 of the MusE
MIDI/Audio sequencer is now available. As you might expect there many
changes since the last release including a switch to Qt5, a new Plugin Path
editor in Global Settings, a mixer makeover with lots of fixes, a
system-wide move to double precision of all audio paths, and much more.

When people upload original content to YouTube, there should be no problem with getting paid for that content, should it attract enough interest from the public.

Those who upload infringing content get a much less easy ride, with their uploads getting flagged for abuse, potentially putting their accounts at risk.

That’s what’s happened to Australia-based music technologist Sebastian Tomczak, who uploaded a completely non-infringing work to YouTube and now faces five separate copyright complaints.

“I teach and work in a music department at a University here in Australia. I’ve got a PhD in chiptune, and my main research interests are various intersections of music / sound / tech e.g. arduino programming and DIY stuff, modular synthesis, digital production, sound design for games, etc,” Tomczak informs TF.

“I started blogging about music around a decade ago or so, mainly to write about stuff I was interested in, researching or doing. At the time this would have been physical interaction, music controller design, sound design and composition involving computers.”

One of Tomczak videos was a masterpiece entitled “10 Hours of Low Level White Noise” which features – wait for it – ten hours of low-level white noise.

“The white noise video was part of a number of videos I put online at the time. I was interested in listening to continuous sounds of various types, and how our perception of these kinds of sounds and our attention changes over longer periods – e.g. distracted, focused, sleeping, waking, working etc,” Tomczak says.

White noise is the sound created when all different frequencies are combined together into a kind of audio mush that’s a little baffling and yet soothing in the right circumstances. Some people use it to fall asleep a little easier, others to distract their attention away from irritating sounds in the environment, like an aircon system or fan, for example.

The white noise made by Tomczak and presented in his video was all his own work.

“I ‘created’ and uploaded the video in question. The video was created by generating a noise waveform of 10 hours length using the freeware software Audacity and the built-in noise generator. The resulting 10-hour audio file was then imported into ScreenFlow, where the text was added and then rendered as one 10-hour video file,” he explains.

This morning, however, Tomczak received a complaint from YouTube after a copyright holder claimed that it had the rights to his composition. When he checked his YouTube account, yet more complaints greeted him. In fact, since July 2015, when the video was first uploaded, a total of five copyright complaints had been filed against Tomczak’s composition.

As seen from the image below, posted by Tomczak to his Twitter account, the five complaints came from four copyright holders, with one feeling the need to file two separate complaints while citing two different works.

The complaints against Tomczak’s white noise

One company involved – Catapult Distribution – say that Tomczak’s composition infringes on the copyrights of “White Noise Sleep Therapy”, a client selling the title “Majestic Ocean Waves”. It also manages to do the same for the company’s “Soothing Baby Sleep” title. The other complaints come from Merlin Symphonic Distribution and Dig Dis for similar works .

Under normal circumstances, Tomczak’s account could have been disabled by YouTube for so many infringements but in all cases the copyright holders chose to monetize the musician’s ‘infringement’ instead, via the site’s ContentID system. In other words, after creating the video himself with his own efforts, copyright holders are now taking all the revenue. It’s a situation that Tomczak will now dispute with YouTube.

“I’ve had quite a few copyright claims against me, usually based on cases where I’ve made long mixes of work, or longer pieces. Usually I don’t take them too seriously,” he explains.

“In any of the cases where I think a given claim would be an issue, I would dispute it by saying I could either prove that I have made the work, have the original materials that generated the work, or could show enough of the components included in the work to prove originality. This has always been successful for me and I hope it will be in this case as well.”

Sadly, this isn’t the only problem Tomczak’s had with YouTube’s copyright complaints system. A while back the musician was asked to take part in a video for his workplace but things didn’t go well.

“I was asked to participate in a video for my workplace and the production team asked if they could use my music and I said ‘no problem’. A month later, the video was uploaded to one of our work channels, and then YouTube generated a copyright claim against me for my own music from the work channel,” he reveals.

Tomczak says that to him, automated copyright claims are largely an annoyance and if he was making enough money from YouTube, the system would be detrimental in the long run. He feels it’s something that YouTube should adjust, to ensure that false claims aren’t filed against uploads like his.

While he tries to sort out this mess with YouTube, there is some good news. Other videos of his including “10 Hours of a Perfect Fifth“, “The First 106 Fifths Derived from a 3/2 Ratio” and “Hour-Long Octave Shift” all remain copyright-complaint free.

For now……

# Tamper-Detection App for Android

Post Syndicated from Bruce Schneier original https://www.schneier.com/blog/archives/2018/01/tamper-detectio.html

Edward Snowden and Nathan Freitas have created an Android app that detects when it’s being tampered with. The basic idea is to put the app on a second phone and put the app on or near something important, like your laptop. The app can then text you — and also record audio and video — when something happens around it: when it’s moved, when the lighting changes, and so on. This gives you some protection against the “evil maid attack” against laptops.

Micah Lee has a good article about the app, including some caveats about its use and security.

# Random with care

Post Syndicated from Eevee original https://eev.ee/blog/2018/01/02/random-with-care/

Hi! Here are a few loose thoughts about picking random numbers.

This is all aimed at frivolous pursuits like video games. Hell, even video games where money is at stake should be deferring to someone who knows way more than I do. Otherwise you might find out that your deck shuffles in your poker game are woefully inadequate and some smartass is cheating you out of millions. (If your random number generator has fewer than 226 bits of state, it can’t even generate every possible shuffling of a deck of cards!)

## Use the right distribution

Most languages have a random number primitive that spits out a number uniformly in the range [0, 1), and you can go pretty far with just that. But beware a few traps!

### Random pitches

Say you want to pitch up a sound by a random amount, perhaps up to an octave. Your audio API probably has a way to do this that takes a pitch multiplier, where I say “probably” because that’s how the only audio API I’ve used works.

Easy peasy. If 1 is unchanged and 2 is pitched up by an octave, then all you need is rand() + 1. Right?

No! Pitch is exponential — within the same octave, the “gap” between C and C♯ is about half as big as the gap between B and the following C. If you pick a pitch multiplier uniformly, you’ll have a noticeable bias towards the higher pitches.

One octave corresponds to a doubling of pitch, so if you want to pick a random note, you want 2 ** rand().

### Random directions

For two dimensions, you can just pick a random angle with rand() * TAU.

If you want a vector rather than an angle, or if you want a random direction in three dimensions, it’s a little trickier. You might be tempted to just pick a random point where each component is rand() * 2 - 1 (ranging from −1 to 1), but that’s not quite right. A direction is a point on the surface (or, equivalently, within the volume) of a sphere, and picking each component independently produces a point within the volume of a cube; the result will be a bias towards the corners of the cube, where there’s much more extra volume beyond the sphere.

No? Well, just trust me. I don’t know how to make a diagram for this.

Anyway, you could use the Pythagorean theorem a few times and make a huge mess of things, or it turns out there’s a really easy way that even works for two or four or any number of dimensions. You pick each coordinate from a Gaussian (normal) distribution, then normalize the resulting vector. In other words, using Python’s random module:

 1 2 3 4 5 6 def random_direction(): x = random.gauss(0, 1) y = random.gauss(0, 1) z = random.gauss(0, 1) r = math.sqrt(x*x + y*y + z*z) return x/r, y/r, z/r 

Why does this work? I have no idea!

Note that it is possible to get zero (or close to it) for every component, in which case the result is nonsense. You can re-roll all the components if necessary; just check that the magnitude (or its square) is less than some epsilon, which is equivalent to throwing away a tiny sphere at the center and shouldn’t affect the distribution.

### Beware Gauss

Since I brought it up: the Gaussian distribution is a pretty nice one for choosing things in some range, where the middle is the common case and should appear more frequently.

That said, I never use it, because it has one annoying drawback: the Gaussian distribution has no minimum or maximum value, so you can’t really scale it down to the range you want. In theory, you might get any value out of it, with no limit on scale.

In practice, it’s astronomically rare to actually get such a value out. I did a hundred million trials just to see what would happen, and the largest value produced was 5.8.

But, still, I’d rather not knowingly put extremely rare corner cases in my code if I can at all avoid it. I could clamp the ends, but that would cause unnatural bunching at the endpoints. I could reroll if I got a value outside some desired range, but I prefer to avoid rerolling when I can, too; after all, it’s still (astronomically) possible to have to reroll for an indefinite amount of time. (Okay, it’s really not, since you’ll eventually hit the period of your PRNG. Still, though.) I don’t bend over backwards here — I did just say to reroll when picking a random direction, after all — but when there’s a nicer alternative I’ll gladly use it.

And lo, there is a nicer alternative! Enter the beta distribution. It always spits out a number in [0, 1], so you can easily swap it in for the standard normal function, but it takes two “shape” parameters α and β that alter its behavior fairly dramatically.

With α = β = 1, the beta distribution is uniform, i.e. no different from rand(). As α increases, the distribution skews towards the right, and as β increases, the distribution skews towards the left. If α = β, the whole thing is symmetric with a hump in the middle. The higher either one gets, the more extreme the hump (meaning that value is far more common than any other). With a little fiddling, you can get a number of interesting curves.

Screenshots don’t really do it justice, so here’s a little Wolfram widget that lets you play with α and β live:

Note that if α = 1, then 1 is a possible value; if β = 1, then 0 is a possible value. You probably want them both greater than 1, which clamps the endpoints to zero.

Also, it’s possible to have either α or β or both be less than 1, but this creates very different behavior: the corresponding endpoints become poles.

Anyway, something like α = β = 3 is probably close enough to normal for most purposes but already clamped for you. And you could easily replicate something like, say, NetHack’s incredibly bizarre rnz function.

### Random frequency

Say you want some event to have an 80% chance to happen every second. You (who am I kidding, I) might be tempted to do something like this:

 1 2 if random() < 0.8 * dt: do_thing() 

In an ideal world, dt is always the same and is equal to 1 / f, where f is the framerate. Replace that 80% with a variable, say P, and every tic you have a P / f chance to do the… whatever it is.

Each second, f tics pass, so you’ll make this check f times. The chance that any check succeeds is the inverse of the chance that every check fails, which is $$1 – \left(1 – \frac{P}{f}\right)^f$$.

For P of 80% and a framerate of 60, that’s a total probability of 55.3%. Wait, what?

Consider what happens if the framerate is 2. On the first tic, you roll 0.4 twice — but probabilities are combined by multiplying, and splitting work up by dt only works for additive quantities. You lose some accuracy along the way. If you’re dealing with something that multiplies, you need an exponent somewhere.

But in this case, maybe you don’t want that at all. Each separate roll you make might independently succeed, so it’s possible (but very unlikely) that the event will happen 60 times within a single second! Or 200 times, if that’s someone’s framerate.

If you explicitly want something to have a chance to happen on a specific interval, you have to check on that interval. If you don’t have a gizmo handy to run code on an interval, it’s easy to do yourself with a time buffer:

 1 2 3 4 5 6 timer += dt # here, 1 is the "every 1 seconds" while timer > 1: timer -= 1 if random() < 0.8: do_thing() 

Using while means rolls still happen even if you somehow skipped over an entire second.

(For the curious, and the nerds who already noticed: the expression $$1 – \left(1 – \frac{P}{f}\right)^f$$ converges to a specific value! As the framerate increases, it becomes a better and better approximation for $$1 – e^{-P}$$, which for the example above is 0.551. Hey, 60 fps is pretty accurate — it’s just accurately representing something nowhere near what I wanted. Er, you wanted.)

### Rolling your own

Of course, you can fuss with the classic [0, 1] uniform value however you want. If I want a bias towards zero, I’ll often just square it, or multiply two of them together. If I want a bias towards one, I’ll take a square root. If I want something like a Gaussian/normal distribution, but with clearly-defined endpoints, I might add together n rolls and divide by n. (The normal distribution is just what you get if you roll infinite dice and divide by infinity!)

It’d be nice to be able to understand exactly what this will do to the distribution. Unfortunately, that requires some calculus, which this post is too small to contain, and which I didn’t even know much about myself until I went down a deep rabbit hole while writing, and which in many cases is straight up impossible to express directly.

Here’s the non-calculus bit. A source of randomness is often graphed as a PDF — a probability density function. You’ve almost certainly seen a bell curve graphed, and that’s a PDF. They’re pretty nice, since they do exactly what they look like: they show the relative chance that any given value will pop out. On a bog standard bell curve, there’s a peak at zero, and of course zero is the most common result from a normal distribution.

(Okay, actually, since the results are continuous, it’s vanishingly unlikely that you’ll get exactly zero — but you’re much more likely to get a value near zero than near any other number.)

For the uniform distribution, which is what a classic rand() gives you, the PDF is just a straight horizontal line — every result is equally likely.

If there were a calculus bit, it would go here! Instead, we can cheat. Sometimes. Mathematica knows how to work with probability distributions in the abstract, and there’s a free web version you can use. For the example of squaring a uniform variable, try this out:

 1 PDF[TransformedDistribution[u^2, u \[Distributed] UniformDistribution[{0, 1}]], u] 

(The \[Distributed] is a funny tilde that doesn’t exist in Unicode, but which Mathematica uses as a first-class operator. Also, press shiftEnter to evaluate the line.)

This will tell you that the distribution is… $$\frac{1}{2\sqrt{u}}$$. Weird! You can plot it:

 1 Plot[%, {u, 0, 1}] 

(The % refers to the result of the last thing you did, so if you want to try several of these, you can just do Plot[PDF[…], u] directly.)

The resulting graph shows that numbers around zero are, in fact, vastly — infinitely — more likely than anything else.

What about multiplying two together? I can’t figure out how to get Mathematica to understand this, but a great amount of digging revealed that the answer is -ln x, and from there you can plot them both on Wolfram Alpha. They’re similar, though squaring has a much better chance of giving you high numbers than multiplying two separate rolls — which makes some sense, since if either of two rolls is a low number, the product will be even lower.

What if you know the graph you want, and you want to figure out how to play with a uniform roll to get it? Good news! That’s a whole thing called inverse transform sampling. All you have to do is take an integral. Good luck!

This is all extremely ridiculous. New tactic: Just Simulate The Damn Thing. You already have the code; run it a million times, make a histogram, and tada, there’s your PDF. That’s one of the great things about computers! Brute-force numerical answers are easy to come by, so there’s no excuse for producing something like rnz. (Though, be sure your histogram has sufficiently narrow buckets — I tried plotting one for rnz once and the weird stuff on the left side didn’t show up at all!)

By the way, I learned something from futzing with Mathematica here! Taking the square root (to bias towards 1) gives a PDF that’s a straight diagonal line, nothing like the hyperbola you get from squaring (to bias towards 0). How do you get a straight line the other way? Surprise: $$1 – \sqrt{1 – u}$$.

### Okay, okay, here’s the actual math

I don’t claim to have a very firm grasp on this, but I had a hell of a time finding it written out clearly, so I might as well write it down as best I can. This was a great excuse to finally set up MathJax, too.

Say $$u(x)$$ is the PDF of the original distribution and $$u$$ is a representative number you plucked from that distribution. For the uniform distribution, $$u(x) = 1$$. Or, more accurately,

$$u(x) = \begin{cases} 1 & \text{ if } 0 \le x \lt 1 \\ 0 & \text{ otherwise } \end{cases}$$

Remember that $$x$$ here is a possible outcome you want to know about, and the PDF tells you the relative probability that a roll will be near it. This PDF spits out 1 for every $$x$$, meaning every number between 0 and 1 is equally likely to appear.

We want to do something to that PDF, which creates a new distribution, whose PDF we want to know. I’ll use my original example of $$f(u) = u^2$$, which creates a new PDF $$v(x)$$.

The trick is that we need to work in terms of the cumulative distribution function for $$u$$. Where the PDF gives the relative chance that a roll will be (“near”) a specific value, the CDF gives the relative chance that a roll will be less than a specific value.

The conventions for this seem to be a bit fuzzy, and nobody bothers to explain which ones they’re using, which makes this all the more confusing to read about… but let’s write the CDF with a capital letter, so we have $$U(x)$$. In this case, $$U(x) = x$$, a straight 45° line (at least between 0 and 1). With the definition I gave, this should make sense. At some arbitrary point like 0.4, the value of the PDF is 1 (0.4 is just as likely as anything else), and the value of the CDF is 0.4 (you have a 40% chance of getting a number from 0 to 0.4).

Calculus ahoy: the PDF is the derivative of the CDF, which means it measures the slope of the CDF at any point. For $$U(x) = x$$, the slope is always 1, and indeed $$u(x) = 1$$. See, calculus is easy.

Okay, so, now we’re getting somewhere. What we want is the CDF of our new distribution, $$V(x)$$. The CDF is defined as the probability that a roll $$v$$ will be less than $$x$$, so we can literally write:

$$V(x) = P(v \le x)$$

(This is why we have to work with CDFs, rather than PDFs — a PDF gives the chance that a roll will be “nearby,” whatever that means. A CDF is much more concrete.)

What is $$v$$, exactly? We defined it ourselves; it’s the do something applied to a roll from the original distribution, or $$f(u)$$.

$$V(x) = P\!\left(f(u) \le x\right)$$

Now the first tricky part: we have to solve that inequality for $$u$$, which means we have to do something, backwards to $$x$$.

$$V(x) = P\!\left(u \le f^{-1}(x)\right)$$

Almost there! We now have a probability that $$u$$ is less than some value, and that’s the definition of a CDF!

$$V(x) = U\!\left(f^{-1}(x)\right)$$

Hooray! Now to turn these CDFs back into PDFs, all we need to do is differentiate both sides and use the chain rule. If you never took calculus, don’t worry too much about what that means!

$$v(x) = u\!\left(f^{-1}(x)\right)\left|\frac{d}{dx}f^{-1}(x)\right|$$

Wait! Where did that absolute value come from? It takes care of whether $$f(x)$$ increases or decreases. It’s the least interesting part here by far, so, whatever.

There’s one more magical part here when using the uniform distribution — $$u(\dots)$$ is always equal to 1, so that entire term disappears! (Note that this only works for a uniform distribution with a width of 1; PDFs are scaled so the entire area under them sums to 1, so if you had a rand() that could spit out a number between 0 and 2, the PDF would be $$u(x) = \frac{1}{2}$$.)

$$v(x) = \left|\frac{d}{dx}f^{-1}(x)\right|$$

So for the specific case of modifying the output of rand(), all we have to do is invert, then differentiate. The inverse of $$f(u) = u^2$$ is $$f^{-1}(x) = \sqrt{x}$$ (no need for a ± since we’re only dealing with positive numbers), and differentiating that gives $$v(x) = \frac{1}{2\sqrt{x}}$$. Done! This is also why square root comes out nicer; inverting it gives $$x^2$$, and differentiating that gives $$2x$$, a straight line.

Incidentally, that method for turning a uniform distribution into any distribution — inverse transform sampling — is pretty much the same thing in reverse: integrate, then invert. For example, when I saw that taking the square root gave $$v(x) = 2x$$, I naturally wondered how to get a straight line going the other way, $$v(x) = 2 – 2x$$. Integrating that gives $$2x – x^2$$, and then you can use the quadratic formula (or just ask Wolfram Alpha) to solve $$2x – x^2 = u$$ for $$x$$ and get $$f(u) = 1 – \sqrt{1 – u}$$.

Multiply two rolls is a bit more complicated; you have to write out the CDF as an integral and you end up doing a double integral and wow it’s a mess. The only thing I’ve retained is that you do a division somewhere, which then gets integrated, and that’s why it ends up as $$-\ln x$$.

And that’s quite enough of that! (Okay but having math in my blog is pretty cool and I will definitely be doing more of this, sorry, not sorry.)

## Random vs varied

Sometimes, random isn’t actually what you want. We tend to use the word “random” casually to mean something more like chaotic, i.e., with no discernible pattern. But that’s not really random. In fact, given how good humans can be at finding incidental patterns, they aren’t all that unlikely! Consider that when you roll two dice, they’ll come up either the same or only one apart almost half the time. Coincidence? Well, yes.

If you ask for randomness, you’re saying that any outcome — or series of outcomes — is acceptable, including five heads in a row or five tails in a row. Most of the time, that’s fine. Some of the time, it’s less fine, and what you really want is variety. Here are a couple examples and some fairly easy workarounds.

### NPC quips

The nature of games is such that NPCs will eventually run out of things to say, at which point further conversation will give the player a short brush-off quip — a slight nod from the designer to the player that, hey, you hit the end of the script.

Some NPCs have multiple possible quips and will give one at random. The trouble with this is that it’s very possible for an NPC to repeat the same quip several times in a row before abruptly switching to another one. With only a few options to choose from, getting the same option twice or thrice (especially across an entire game, which may have numerous NPCs) isn’t all that unlikely. The notion of an NPC quip isn’t very realistic to start with, but having someone repeat themselves and then abruptly switch to something else is especially jarring.

The easy fix is to show the quips in order! Paradoxically, this is more consistently varied than choosing at random — the original “order” is likely to be meaningless anyway, and it already has the property that the same quip can never appear twice in a row.

If you like, you can shuffle the list of quips every time you reach the end, but take care here — it’s possible that the last quip in the old order will be the same as the first quip in the new order, so you may still get a repeat. (Of course, you can just check for this case and swap the first quip somewhere else if it bothers you.)

That last behavior is, in fact, the canonical way that Tetris chooses pieces — the game simply shuffles a list of all 7 pieces, gives those to you in shuffled order, then shuffles them again to make a new list once it’s exhausted. There’s no avoidance of duplicates, though, so you can still get two S blocks in a row, or even two S and two Z all clumped together, but no more than that. Some Tetris variants take other approaches, such as actively avoiding repeats even several pieces apart or deliberately giving you the worst piece possible.

### Random drops

Random drops are often implemented as a flat chance each time. Maybe enemies have a 5% chance to drop health when they die. Legally speaking, over the long term, a player will see health drops for about 5% of enemy kills.

Over the short term, they may be desperate for health and not survive to see the long term. So you may want to put a thumb on the scale sometimes. Games in the Metroid series, for example, have a somewhat infamous bias towards whatever kind of drop they think you need — health if your health is low, missiles if your missiles are low.

I can’t give you an exact approach to use, since it depends on the game and the feeling you’re going for and the variables at your disposal. In extreme cases, you might want to guarantee a health drop from a tough enemy when the player is critically low on health. (Or if you’re feeling particularly evil, you could go the other way and deny the player health when they most need it…)

The problem becomes a little different, and worse, when the event that triggers the drop is relatively rare. The pathological case here would be something like a raid boss in World of Warcraft, which requires hours of effort from a coordinated group of people to defeat, and which has some tiny chance of dropping a good item that will go to only one of those people. This is why I stopped playing World of Warcraft at 60.

Dialing it back a little bit gives us Enter the Gungeon, a roguelike where each room is a set of encounters and each floor only has a dozen or so rooms. Initially, you have a 1% chance of getting a reward after completing a room — but every time you complete a room and don’t get a reward, the chance increases by 9%, up to a cap of 80%. Once you get a reward, the chance resets to 1%.

The natural question is: how frequently, exactly, can a player expect to get a reward? We could do math, or we could Just Simulate The Damn Thing.

  1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 from collections import Counter import random histogram = Counter() TRIALS = 1000000 chance = 1 rooms_cleared = 0 rewards_found = 0 while rewards_found < TRIALS: rooms_cleared += 1 if random.random() * 100 < chance: # Reward! rewards_found += 1 histogram[rooms_cleared] += 1 rooms_cleared = 0 chance = 1 else: chance = min(80, chance + 9) for gaps, count in sorted(histogram.items()): print(f"{gaps:3d} | {count / TRIALS * 100:6.2f}%", '#' * (count // (TRIALS // 100))) 
  1 2 3 4 5 6 7 8 9 10 11 12 13 14 15  1 | 0.98% 2 | 9.91% ######### 3 | 17.00% ################ 4 | 20.23% #################### 5 | 19.21% ################### 6 | 15.05% ############### 7 | 9.69% ######### 8 | 5.07% ##### 9 | 2.09% ## 10 | 0.63% 11 | 0.12% 12 | 0.03% 13 | 0.00% 14 | 0.00% 15 | 0.00% 

We’ve got kind of a hilly distribution, skewed to the left, which is up in this histogram. Most of the time, a player should see a reward every three to six rooms, which is maybe twice per floor. It’s vanishingly unlikely to go through a dozen rooms without ever seeing a reward, so a player should see at least one per floor.

Of course, this simulated a single continuous playthrough; when starting the game from scratch, your chance at a reward always starts fresh at 1%, the worst it can be. If you want to know about how many rewards a player will get on the first floor, hey, Just Simulate The Damn Thing.

 1 2 3 4 5 6 7  0 | 0.01% 1 | 13.01% ############# 2 | 56.28% ######################################################## 3 | 27.49% ########################### 4 | 3.10% ### 5 | 0.11% 6 | 0.00% 

Cool. Though, that’s assuming exactly 12 rooms; it might be worth changing that to pick at random in a way that matches the level generator.

(Enter the Gungeon does some other things to skew probability, which is very nice in a roguelike where blind luck can make or break you. For example, if you kill a boss without having gotten a new gun anywhere else on the floor, the boss is guaranteed to drop a gun.)

### Critical hits

I suppose this is the same problem as random drops, but backwards.

Say you have a battle sim where every attack has a 6% chance to land a devastating critical hit. Presumably the same rules apply to both the player and the AI opponents.

Consider, then, that the AI opponents have exactly the same 6% chance to ruin the player’s day. Consider also that this gives them an 0.4% chance to critical hit twice in a row. 0.4% doesn’t sound like much, but across an entire playthrough, it’s not unlikely that a player might see it happen and find it incredibly annoying.

Perhaps it would be worthwhile to explicitly forbid AI opponents from getting consecutive critical hits.

## In conclusion

An emerging theme here has been to Just Simulate The Damn Thing. So consider Just Simulating The Damn Thing. Even a simple change to a random value can do surprising things to the resulting distribution, so unless you feel like differentiating the inverse function of your code, maybe test out any non-trivial behavior and make sure it’s what you wanted. Probability is hard to reason about.
