Build your own weather station with our new guide!

Post Syndicated from Richard Hayler original https://www.raspberrypi.org/blog/build-your-own-weather-station/

One of the most common enquiries I receive at Pi Towers is “How can I get my hands on a Raspberry Pi Oracle Weather Station?” Now the answer is: “Why not build your own version using our guide?”

Build Your Own weather station kit assembled

Tadaaaa! The BYO weather station fully assembled.

Our Oracle Weather Station

In 2016 we sent out nearly 1000 Raspberry Pi Oracle Weather Station kits to schools from around the world who had applied to be part of our weather station programme. In the original kit was a special HAT that allows the Pi to collect weather data with a set of sensors.

The original Raspberry Pi Oracle Weather Station HAT – Build Your Own Raspberry Pi weather station

The original Raspberry Pi Oracle Weather Station HAT

We designed the HAT to enable students to create their own weather stations and mount them at their schools. As part of the programme, we also provide an ever-growing range of supporting resources. We’ve seen Oracle Weather Stations in great locations with a huge differences in climate, and they’ve even recorded the effects of a solar eclipse.

Our new BYO weather station guide

We only had a single batch of HATs made, and unfortunately we’ve given nearly* all the Weather Station kits away. Not only are the kits really popular, we also receive lots of questions about how to add extra sensors or how to take more precise measurements of a particular weather phenomenon. So today, to satisfy your demand for a hackable weather station, we’re launching our Build your own weather station guide!

Build Your Own Raspberry Pi weather station

Fun with meteorological experiments!

Our guide suggests the use of many of the sensors from the Oracle Weather Station kit, so can build a station that’s as close as possible to the original. As you know, the Raspberry Pi is incredibly versatile, and we’ve made it easy to hack the design in case you want to use different sensors.

Many other tutorials for Pi-powered weather stations don’t explain how the various sensors work or how to store your data. Ours goes into more detail. It shows you how to put together a breadboard prototype, it describes how to write Python code to take readings in different ways, and it guides you through recording these readings in a database.

Build Your Own Raspberry Pi weather station on a breadboard

There’s also a section on how to make your station weatherproof. And in case you want to move past the breadboard stage, we also help you with that. The guide shows you how to solder together all the components, similar to the original Oracle Weather Station HAT.

Who should try this build

We think this is a great project to tackle at home, at a STEM club, Scout group, or CoderDojo, and we’re sure that many of you will be chomping at the bit to get started. Before you do, please note that we’ve designed the build to be as straight-forward as possible, but it’s still fairly advanced both in terms of electronics and programming. You should read through the whole guide before purchasing any components.

Build Your Own Raspberry Pi weather station – components

The sensors and components we’re suggesting balance cost, accuracy, and easy of use. Depending on what you want to use your station for, you may wish to use different components. Similarly, the final soldered design in the guide may not be the most elegant, but we think it is achievable for someone with modest soldering experience and basic equipment.

You can build a functioning weather station without soldering with our guide, but the build will be more durable if you do solder it. If you’ve never tried soldering before, that’s OK: we have a Getting started with soldering resource plus video tutorial that will walk you through how it works step by step.

Prototyping HAT for Raspberry Pi weather station sensors

For those of you who are more experienced makers, there are plenty of different ways to put the final build together. We always like to hear about alternative builds, so please post your designs in the Weather Station forum.

Our plans for the guide

Our next step is publishing supplementary guides for adding extra functionality to your weather station. We’d love to hear which enhancements you would most like to see! Our current ideas under development include adding a webcam, making a tweeting weather station, adding a light/UV meter, and incorporating a lightning sensor. Let us know which of these is your favourite, or suggest your own amazing ideas in the comments!

*We do have a very small number of kits reserved for interesting projects or locations: a particularly cool experiment, a novel idea for how the Oracle Weather Station could be used, or places with specific weather phenomena. If have such a project in mind, please send a brief outline to [email protected], and we’ll consider how we might be able to help you.

Flight Sim Company Threatens Reddit Mods Over “Libelous” DRM Posts

Post Syndicated from Andy original https://torrentfreak.com/flight-sim-company-threatens-reddit-mods-over-libellous-drm-posts-180604/

Earlier this year, in an effort to deal with piracy of their products, flight simulator company FlightSimLabs took drastic action by installing malware on customers’ machines.

The story began when a Reddit user reported something unusual in his download of FlightSimLabs’ A320X module. A file – test.exe – was being flagged up as a ‘Chrome Password Dump’ tool, something which rang alarm bells among flight sim fans.

As additional information was made available, the story became even more sensational. After first dodging the issue with carefully worded statements, FlightSimLabs admitted that it had installed a password dumper onto ALL users’ machines – whether they were pirates or not – in an effort to catch a particular software cracker and launch legal action.

It was an incredible story that no doubt did damage to FlightSimLabs’ reputation. But the now the company is at the center of a new storm, again centered around anti-piracy measures and again focused on Reddit.

Just before the weekend, Reddit user /u/walkday reported finding something unusual in his A320X module, the same module that caused the earlier controversy.

“The latest installer of FSLabs’ A320X puts two cmdhost.exe files under ‘system32\’ and ‘SysWOW64\’ of my Windows directory. Despite the name, they don’t open a command-line window,” he reported.

“They’re a part of the authentication because, if you remove them, the A320X won’t get loaded. Does someone here know more about cmdhost.exe? Why does FSLabs give them such a deceptive name and put them in the system folders? I hate them for polluting my system folder unless, of course, it is a dll used by different applications.”

Needless to say, the news that FSLabs were putting files into system folders named to make them look like system files was not well received.

“Hiding something named to resemble Window’s “Console Window Host” process in system folders is a huge red flag,” one user wrote.

“It’s a malware tactic used to deceive users into thinking the executable is a part of the OS, thus being trusted and not deleted. Really dodgy tactic, don’t trust it and don’t trust them,” opined another.

With a disenchanted Reddit userbase simmering away in the background, FSLabs took to Facebook with a statement to quieten down the masses.

“Over the past few hours we have become aware of rumors circulating on social media about the cmdhost file installed by the A320-X and wanted to clear up any confusion or misunderstanding,” the company wrote.

“cmdhost is part of our eSellerate infrastructure – which communicates between the eSellerate server and our product activation interface. It was designed to reduce the number of product activation issues people were having after the FSX release – which have since been resolved.”

The company noted that the file had been checked by all major anti-virus companies and everything had come back clean, which does indeed appear to be the case. Nevertheless, the critical Reddit thread remained, bemoaning the actions of a company which probably should have known better than to irritate fans after February’s debacle. In response, however, FSLabs did just that once again.

In private messages to the moderators of the /r/flightsim sub-Reddit, FSLabs’ Marketing and PR Manager Simon Kelsey suggested that the mods should do something about the thread in question or face possible legal action.

“Just a gentle reminder of Reddit’s obligations as a publisher in order to ensure that any libelous content is taken down as soon as you become aware of it,” Kelsey wrote.

Noting that FSLabs welcomes “robust fair comment and opinion”, Kelsey gave the following advice.

“The ‘cmdhost.exe’ file in question is an entirely above board part of our anti-piracy protection and has been submitted to numerous anti-virus providers in order to verify that it poses no threat. Therefore, ANY suggestion that current or future products pose any threat to users is absolutely false and libelous,” he wrote, adding:

“As we have already outlined in the past, ANY suggestion that any user’s data was compromised during the events of February is entirely false and therefore libelous.”

Noting that FSLabs would “hate for lawyers to have to get involved in this”, Kelsey advised the /r/flightsim mods to ensure that no such claims were allowed to remain on the sub-Reddit.

But after not receiving the response he would’ve liked, Kelsey wrote once again to the mods. He noted that “a number of unsubstantiated and highly defamatory comments” remained online and warned that if something wasn’t done to clean them up, he would have “no option” than to pass the matter to FSLabs’ legal team.

Like the first message, this second effort also failed to have the desired effect. In fact, the moderators’ response was to post an open letter to Kelsey and FSLabs instead.

“We sincerely disagree that you ‘welcome robust fair comment and opinion’, demonstrated by the censorship on your forums and the attempted censorship on our subreddit,” the mods wrote.

“While what you do on your forum is certainly your prerogative, your rules do not extend to Reddit nor the r/flightsim subreddit. Removing content you disagree with is simply not within our purview.”

The letter, which is worth reading in full, refutes Kelsey’s claims and also suggests that critics of FSLabs may have been subjected to Reddit vote manipulation and coordinated efforts to discredit them.

What will happen next is unclear but the matter has now been placed in the hands of Reddit’s administrators who have agreed to deal with Kelsey and FSLabs’ personally.

It’s a little early to say for sure but it seems unlikely that this will end in a net positive for FSLabs, no matter what decision Reddit’s admins take.

When Joe Public Becomes a Commercial Pirate, a Little Knowledge is Dangerous

Post Syndicated from Andy original https://torrentfreak.com/joe-public-becomes-commercial-pirate-little-knowledge-dangerous-180603/

Back in March and just a few hours before the Anthony Joshua v Joseph Parker fight, I got chatting with some fellow fans in the local pub. While some were intending to pay for the fight, others were going down the Kodi route.

Soon after the conversation switched to IPTV. One of the guys had a subscription and he said that his supplier would be along shortly if anyone wanted a package to watch the fight at home. Of course, I was curious to hear what he had to say since it’s not often this kind of thing is offered ‘offline’.

The guy revealed that he sold more or less exclusively on eBay and called up the page on his phone to show me. The listing made interesting reading.

In common with hundreds of similar IPTV subscription offers easily findable on eBay, the listing offered “All the sports and films you need plus VOD and main UK channels” for the sum of just under £60 per year, which is fairly cheap in the current market. With a non-committal “hmmm” I asked a bit more about the guy’s business and surprisingly he was happy to provide some details.

Like many people offering such packages, the guy was a reseller of someone else’s product. He also insisted that selling access to copyrighted content is OK because it sits in a “gray area”. It’s also easy to keep listings up on eBay, he assured me, as long as a few simple rules are adhered to. Right, this should be interesting.

First of all, sellers shouldn’t be “too obvious” he advised, noting that individual channels or channel lists shouldn’t be listed on the site. Fair enough, but then he said the most important thing of all is to have a disclaimer like his in any listing, written as follows:

“PLEASE NOTE EBAY: THIS IS NOT A DE SCRAMBLER SERVICE, I AM NOT SELLING ANY ILLEGAL CHANNELS OR CHANNEL LISTS NOR DO I REPRESENT ANY MEDIA COMPANY NOR HAVE ACCESS TO ANY OF THEIR CONTENTS. NO TRADEMARK HAS BEEN INFRINGED. DO NOT REMOVE LISTING AS IT IS IN ACCORDANCE WITH EBAY POLICIES.”

Apparently, this paragraph is crucial to keeping listings up on eBay and is the equivalent of kryptonite when it comes to deflecting copyright holders, police, and Trading Standards. Sure enough, a few seconds with Google reveals the same wording on dozens of eBay listings and those offering IPTV subscriptions on external platforms.

It is, of course, absolutely worthless but the IPTV seller insisted otherwise, noting he’d sold “thousands” of subscriptions through eBay without any problems. While a similar logic can be applied to garlic and vampires, a second disclaimer found on many other illicit IPTV subscription listings treads an even more bizarre path.

“THE PRODUCTS OFFERED CAN NOT BE USED TO DESCRAMBLE OR OTHERWISE ENABLE ACCESS TO CABLE OR SATELLITE TELEVISION PROGRAMS THAT BYPASSES PAYMENT TO THE SERVICE PROVIDER. RECEIVING SUBSCRIPTION/BASED TV AIRTIME IS ILLEGAL WITHOUT PAYING FOR IT.”

This disclaimer (which apparently no sellers displaying it have ever read) seems to be have been culled from the Zgemma site, which advertises a receiving device which can technically receive pirate IPTV services but wasn’t designed for the purpose. In that context, the disclaimer makes sense but when applied to dedicated pirate IPTV subscriptions, it’s absolutely ridiculous.

It’s unclear why so many sellers on eBay, Gumtree, Craigslist and other platforms think that these disclaimers are useful. It leads one to the likely conclusion that these aren’t hardcore pirates at all but regular people simply out to make a bit of extra cash who have received bad advice.

What is clear, however, is that selling access to thousands of otherwise subscription channels without permission from copyright owners is definitely illegal in the EU. The European Court of Justice says so (1,2) and it’s been backed up by subsequent cases in the Netherlands.

While the odds of getting criminally prosecuted or sued for reselling such a service are relatively slim, it’s worrying that in 2018 people still believe that doing so is made legal by the inclusion of a paragraph of text. It’s even more worrying that these individuals apparently have no idea of the serious consequences should they become singled out for legal action.

Even more surprisingly, TorrentFreak spoke with a handful of IPTV suppliers higher up the chain who also told us that what they are doing is legal. A couple claimed to be protected by communication intermediary laws, others didn’t want to go into details. Most stopped responding to emails on the topic. Perhaps most tellingly, none wanted to go on the record.

The big take-home here is that following some important EU rulings, knowingly linking to copyrighted content for profit is nearly always illegal in Europe and leaves people open for targeting by copyright holders and the authorities. People really should be aware of that, especially the little guy making a little extra pocket money on eBay.

Of course, people are perfectly entitled to carry on regardless and test the limits of the law when things go wrong. At this point, however, it’s probably worth noting that IPTV provider Ace Hosting recently handed over £600,000 rather than fight the Premier League (1,2) when they clearly had the money to put up a defense.

Given their effectiveness, perhaps they should’ve put up a disclaimer instead?

Storing Encrypted Credentials In Git

Post Syndicated from Bozho original https://techblog.bozho.net/storing-encrypted-credentials-in-git/

We all know that we should not commit any passwords or keys to the repo with our code (no matter if public or private). Yet, thousands of production passwords can be found on GitHub (and probably thousands more in internal company repositories). Some have tried to fix that by removing the passwords (once they learned it’s not a good idea to store them publicly), but passwords have remained in the git history.

Knowing what not to do is the first and very important step. But how do we store production credentials. Database credentials, system secrets (e.g. for HMACs), access keys for 3rd party services like payment providers or social networks. There doesn’t seem to be an agreed upon solution.

I’ve previously argued with the 12-factor app recommendation to use environment variables – if you have a few that might be okay, but when the number of variables grow (as in any real application), it becomes impractical. And you can set environment variables via a bash script, but you’d have to store it somewhere. And in fact, even separate environment variables should be stored somewhere.

This somewhere could be a local directory (risky), a shared storage, e.g. FTP or S3 bucket with limited access, or a separate git repository. I think I prefer the git repository as it allows versioning (Note: S3 also does, but is provider-specific). So you can store all your environment-specific properties files with all their credentials and environment-specific configurations in a git repo with limited access (only Ops people). And that’s not bad, as long as it’s not the same repo as the source code.

Such a repo would look like this:

project
└─── production
|   |   application.properites
|   |   keystore.jks
└─── staging
|   |   application.properites
|   |   keystore.jks
└─── on-premise-client1
|   |   application.properites
|   |   keystore.jks
└─── on-premise-client2
|   |   application.properites
|   |   keystore.jks

Since many companies are using GitHub or BitBucket for their repositories, storing production credentials on a public provider may still be risky. That’s why it’s a good idea to encrypt the files in the repository. A good way to do it is via git-crypt. It is “transparent” encryption because it supports diff and encryption and decryption on the fly. Once you set it up, you continue working with the repo as if it’s not encrypted. There’s even a fork that works on Windows.

You simply run git-crypt init (after you’ve put the git-crypt binary on your OS Path), which generates a key. Then you specify your .gitattributes, e.g. like that:

secretfile filter=git-crypt diff=git-crypt
*.key filter=git-crypt diff=git-crypt
*.properties filter=git-crypt diff=git-crypt
*.jks filter=git-crypt diff=git-crypt

And you’re done. Well, almost. If this is a fresh repo, everything is good. If it is an existing repo, you’d have to clean up your history which contains the unencrypted files. Following these steps will get you there, with one addition – before calling git commit, you should call git-crypt status -f so that the existing files are actually encrypted.

You’re almost done. We should somehow share and backup the keys. For the sharing part, it’s not a big issue to have a team of 2-3 Ops people share the same key, but you could also use the GPG option of git-crypt (as documented in the README). What’s left is to backup your secret key (that’s generated in the .git/git-crypt directory). You can store it (password-protected) in some other storage, be it a company shared folder, Dropbox/Google Drive, or even your email. Just make sure your computer is not the only place where it’s present and that it’s protected. I don’t think key rotation is necessary, but you can devise some rotation procedure.

git-crypt authors claim to shine when it comes to encrypting just a few files in an otherwise public repo. And recommend looking at git-remote-gcrypt. But as often there are non-sensitive parts of environment-specific configurations, you may not want to encrypt everything. And I think it’s perfectly fine to use git-crypt even in a separate repo scenario. And even though encryption is an okay approach to protect credentials in your source code repo, it’s still not necessarily a good idea to have the environment configurations in the same repo. Especially given that different people/teams manage these credentials. Even in small companies, maybe not all members have production access.

The outstanding questions in this case is – how do you sync the properties with code changes. Sometimes the code adds new properties that should be reflected in the environment configurations. There are two scenarios here – first, properties that could vary across environments, but can have default values (e.g. scheduled job periods), and second, properties that require explicit configuration (e.g. database credentials). The former can have the default values bundled in the code repo and therefore in the release artifact, allowing external files to override them. The latter should be announced to the people who do the deployment so that they can set the proper values.

The whole process of having versioned environment-speific configurations is actually quite simple and logical, even with the encryption added to the picture. And I think it’s a good security practice we should try to follow.

Protecting coral reefs with Nemo-Pi, the underwater monitor

Post Syndicated from Janina Ander original https://www.raspberrypi.org/blog/coral-reefs-nemo-pi/

The German charity Save Nemo works to protect coral reefs, and they are developing Nemo-Pi, an underwater “weather station” that monitors ocean conditions. Right now, you can vote for Save Nemo in the Google.org Impact Challenge.

Nemo-Pi — Save Nemo

Save Nemo

The organisation says there are two major threats to coral reefs: divers, and climate change. To make diving saver for reefs, Save Nemo installs buoy anchor points where diving tour boats can anchor without damaging corals in the process.

In addition, they provide dos and don’ts for how to behave on a reef dive.

The Nemo-Pi

To monitor the effects of climate change, and to help divers decide whether conditions are right at a reef while they’re still on shore, Save Nemo is also in the process of perfecting Nemo-Pi.

Nemo-Pi schematic — Nemo-Pi — Save Nemo

This Raspberry Pi-powered device is made up of a buoy, a solar panel, a GPS device, a Pi, and an array of sensors. Nemo-Pi measures water conditions such as current, visibility, temperature, carbon dioxide and nitrogen oxide concentrations, and pH. It also uploads its readings live to a public webserver.

Long-term goals

Save Nemo aims to install a network of Nemo-Pis at shallow reefs (up to 60 metres deep) in South East Asia. Then diving tour companies can check the live data online and decide day-to-day whether tours are feasible. This will lower the impact of humans on reefs and help the local flora and fauna survive.

Coral reefs with fishes

Nemo-Pi data may also be useful for groups lobbying for reef conservation, and for scientists and activists who want to shine a spotlight on the awful effects of climate change on sea life, such as coral bleaching caused by rising water temperatures.

Majority of Canadians Consume Online Content Legally, Survey Finds

Post Syndicated from Andy original https://torrentfreak.com/majority-of-canadians-consume-online-content-legally-survey-finds-180531/

Back in January, a coalition of companies and organizations with ties to the entertainment industries called on local telecoms regulator CRTC to implement a national website blocking regime.

Under the banner of Fairplay Canada, members including Bell, Cineplex, Directors Guild of Canada, Maple Leaf Sports and Entertainment, Movie Theatre Association of Canada, and Rogers Media, spoke of an industry under threat from marauding pirates. But just how serious is this threat?

The results of a new survey commissioned by Innovation Science and Economic Development Canada (ISED) in collaboration with the Department of Canadian Heritage (PCH) aims to shine light on the problem by revealing the online content consumption habits of citizens in the Great White North.

While there are interesting findings for those on both sides of the site-blocking debate, the situation seems somewhat removed from the Armageddon scenario predicted by the entertainment industries.

Carried out among 3,301 Canadians aged 12 years and over, the Kantar TNS study aims to cover copyright infringement in six key content areas – music, movies, TV shows, video games, computer software, and eBooks. Attitudes and behaviors are also touched upon while measuring the effectiveness of Canada’s copyright measures.

General Digital Content Consumption

In its introduction, the report notes that 28 million Canadians used the Internet in the three-month study period to November 27, 2017. Of those, 22 million (80%) consumed digital content. Around 20 million (73%) streamed or accessed content, 16 million (59%) downloaded content, while 8 million (28%) shared content.

Music, TV shows and movies all battled for first place in the consumption ranks, with 48%, 48%, and 46% respectively.

Copyright Infringement

According to the study, the majority of Canadians do things completely by the book. An impressive 74% of media-consuming respondents said that they’d only accessed material from legal sources in the preceding three months.

The remaining 26% admitted to accessing at least one illegal file in the same period. Of those, just 5% said that all of their consumption was from illegal sources, with movies (36%), software (36%), TV shows (34%) and video games (33%) the most likely content to be consumed illegally.

Interestingly, the study found that few demographic factors – such as gender, region, rural and urban, income, employment status and language – play a role in illegal content consumption.

“We found that only age and income varied significantly between consumers who infringed by downloading or streaming/accessing content online illegally and consumers who did not consume infringing content online,” the report reads.

“More specifically, the profile of consumers who downloaded or streamed/accessed infringing content skewed slightly younger and towards individuals with household incomes of $100K+.”

Licensed services much more popular than pirate haunts

It will come as no surprise that Netflix was the most popular service with consumers, with 64% having used it in the past three months. Sites like YouTube and Facebook were a big hit too, visited by 36% and 28% of content consumers respectively.

Overall, 74% of online content consumers use licensed services for content while 42% use social networks. Under a third (31%) use a combination of peer-to-peer (BitTorrent), cyberlocker platforms, or linking sites. Stream-ripping services are used by 9% of content consumers.

“Consumers who reported downloading or streaming/accessing infringing content only are less likely to use licensed services and more likely to use peer-to-peer/cyberlocker/linking sites than other consumers of online content,” the report notes.

Attitudes towards legal consumption & infringing content

In common with similar surveys over the years, the Kantar research looked at the reasons why people consume content from various sources, both legal and otherwise.

Convenience (48%), speed (36%) and quality (34%) were the most-cited reasons for using legal sources. An interesting 33% of respondents said they use legal sites to avoid using illegal sources.

On the illicit front, 54% of those who obtained unauthorized content in the previous three months said they did so due to it being free, with 40% citing convenience and 34% mentioning speed.

Almost six out of ten (58%) said lower costs would encourage them to switch to official sources, with 47% saying they’d move if legal availability was improved.

Canada’s ‘Notice-and-Notice’ warning system

People in Canada who share content on peer-to-peer systems like BitTorrent without permission run the risk of receiving an infringement notice warning them to stop. These are sent by copyright holders via users’ ISPs and the hope is that the shock of receiving a warning will turn consumers back to the straight and narrow.

The study reveals that 10% of online content consumers over the age of 12 have received one of these notices but what kind of effect have they had?

“Respondents reported that receiving such a notice resulted in the following: increased awareness of copyright infringement (38%), taking steps to ensure password protected home networks (27%), a household discussion about copyright infringement (27%), and discontinuing illegal downloading or streaming (24%),” the report notes.

While these are all positives for the entertainment industries, Kantar reports that almost a quarter (24%) of people who receive a notice simply ignore them.

Stream-ripping

Once upon a time, people obtaining music via P2P networks was cited as the music industry’s greatest threat but, with the advent of sites like YouTube, so-called stream-ripping is the latest bogeyman.

According to the study, 11% of Internet users say they’ve used a stream-ripping service. They are most likely to be male (62%) and predominantly 18 to 34 (52%) years of age.

“Among Canadians who have used a service to stream-rip music or entertainment, nearly half (48%) have used stream-ripping sites, one-third have used downloader apps (38%), one-in-seven (14%) have used a stream-ripping plug-in, and one-in-ten (10%) have used stream-ripping software,” the report adds.

Set-Top Boxes and VPNs

Few general piracy studies would be complete in 2018 without touching on set-top devices and Virtual Private Networks and this report doesn’t disappoint.

More than one in five (21%) respondents aged 12+ reported using a VPN, with the main purpose of securing communications and Internet browsing (57%).

A relatively modest 36% said they use a VPN to access free content while 32% said the aim was to access geo-blocked content unavailable in Canada. Just over a quarter (27%) said that accessing content from overseas at a reasonable price was the main motivator.

One in ten (10%) of respondents reported using a set-top box, with 78% stating they use them to access paid-for content. Interestingly, only a small number say they use the devices to infringe.

“A minority use set-top boxes to access other content that is not legal or they are unsure if it is legal (16%), or to access live sports that are not legal or they are unsure if it is legal (11%),” the report notes.

“Individuals who consumed a mix of legal and illegal content online are more likely to use VPN services (42%) or TV set-top boxes (21%) than consumers who only downloaded or streamed/accessed legal content.”

Kantar says that the findings of the report will be used to help policymakers evaluate how Canada’s Copyright Act is coping with a changing market and technological developments.

“This research will provide the necessary information required to further develop copyright policy in Canada, as well as to provide a foundation to assess the effectiveness of the measures to address copyright infringement, should future analysis be undertaken,” it concludes.

Hiring a Director of Sales

Post Syndicated from Yev original https://www.backblaze.com/blog/hiring-a-director-of-sales/

Backblaze is hiring a Director of Sales. This is a critical role for Backblaze as we continue to grow the team. We need a strong leader who has experience in scaling a sales team and who has an excellent track record for exceeding goals by selling Software as a Service (SaaS) solutions. In addition, this leader will need to be highly motivated, as well as able to create and develop a highly-motivated, success oriented sales team that has fun and enjoys what they do.

The History of Backblaze from our CEO
In 2007, after a friend’s computer crash caused her some suffering, we realized that with every photo, video, song, and document going digital, everyone would eventually lose all of their information. Five of us quit our jobs to start a company with the goal of making it easy for people to back up their data.

Like many startups, for a while we worked out of a co-founder’s one-bedroom apartment. Unlike most startups, we made an explicit agreement not to raise funding during the first year. We would then touch base every six months and decide whether to raise or not. We wanted to focus on building the company and the product, not on pitching and slide decks. And critically, we wanted to build a culture that understood money comes from customers, not the magical VC giving tree. Over the course of 5 years we built a profitable, multi-million dollar revenue business — and only then did we raise a VC round.

Fast forward 10 years later and our world looks quite different. You’ll have some fantastic assets to work with:

  • A brand millions recognize for openness, ease-of-use, and affordability.
  • A computer backup service that stores over 500 petabytes of data, has recovered over 30 billion files for hundreds of thousands of paying customers — most of whom self-identify as being the people that find and recommend technology products to their friends.
  • Our B2 service that provides the lowest cost cloud storage on the planet at 1/4th the price Amazon, Google or Microsoft charges. While being a newer product on the market, it already has over 100,000 IT and developers signed up as well as an ecosystem building up around it.
  • A growing, profitable and cash-flow positive company.
  • And last, but most definitely not least: a great sales team.

You might be saying, “sounds like you’ve got this under control — why do you need me?” Don’t be misled. We need you. Here’s why:

  • We have a great team, but we are in the process of expanding and we need to develop a structure that will easily scale and provide the most success to drive revenue.
  • We just launched our outbound sales efforts and we need someone to help develop that into a fully successful program that’s building a strong pipeline and closing business.
  • We need someone to work with the marketing department and figure out how to generate more inbound opportunities that the sales team can follow up on and close.
  • We need someone who will work closely in developing the skills of our current sales team and build a path for career growth and advancement.
  • We want someone to manage our Customer Success program.

So that’s a bit about us. What are we looking for in you?

Experience: As a sales leader, you will strategically build and drive the territory’s sales pipeline by assembling and leading a skilled team of sales professionals. This leader should be familiar with generating, developing and closing software subscription (SaaS) opportunities. We are looking for a self-starter who can manage a team and make an immediate impact of selling our Backup and Cloud Storage solutions. In this role, the sales leader will work closely with the VP of Sales, marketing staff, and service staff to develop and implement specific strategic plans to achieve and exceed revenue targets, including new business acquisition as well as build out our customer success program.

Leadership: We have an experienced team who’s brought us to where we are today. You need to have the people and management skills to get them excited about working with you. You need to be a strong leader and compassionate about developing and supporting your team.

Data driven and creative: The data has to show something makes sense before we scale it up. However, without creativity, it’s easy to say “the data shows it’s impossible” or to find a local maximum. Whether it’s deciding how to scale the team, figuring out what our outbound sales efforts should look like or putting a plan in place to develop the team for career growth, we’ve seen a bit of creativity get us places a few extra dollars couldn’t.

Jive with our culture: Strong leaders affect culture and the person we hire for this role may well shape, not only fit into, ours. But to shape the culture you have to be accepted by the organism, which means a certain set of shared values. We default to openness with our team, our customers, and everyone if possible. We love initiative — without arrogance or dictatorship. We work to create a place people enjoy showing up to work. That doesn’t mean ping pong tables and foosball (though we do try to have perks & fun), but it means people are friendly, non-political, working to build a good service but also a good place to work.

Do the work: Ideas and strategy are critical, but good execution makes them happen. We’re looking for someone who can help the team execute both from the perspective of being capable of guiding and organizing, but also someone who is hands-on themselves.

Additional Responsibilities needed for this role:

  • Recruit, coach, mentor, manage and lead a team of sales professionals to achieve yearly sales targets. This includes closing new business and expanding upon existing clientele.
  • Expand the customer success program to provide the best customer experience possible resulting in upsell opportunities and a high retention rate.
  • Develop effective sales strategies and deliver compelling product demonstrations and sales pitches.
  • Acquire and develop the appropriate sales tools to make the team efficient in their daily work flow.
  • Apply a thorough understanding of the marketplace, industry trends, funding developments, and products to all management activities and strategic sales decisions.
  • Ensure that sales department operations function smoothly, with the goal of facilitating sales and/or closings; operational responsibilities include accurate pipeline reporting and sales forecasts.
  • This position will report directly to the VP of Sales and will be staffed in our headquarters in San Mateo, CA.

Requirements:

  • 7 – 10+ years of successful sales leadership experience as measured by sales performance against goals.
    Experience in developing skill sets and providing career growth and opportunities through advancement of team members.
  • Background in selling SaaS technologies with a strong track record of success.
  • Strong presentation and communication skills.
  • Must be able to travel occasionally nationwide.
  • BA/BS degree required

Think you want to join us on this adventure?
Send an email to jobscontact@backblaze.com with the subject “Director of Sales.” (Recruiters and agencies, please don’t email us.) Include a resume and answer these two questions:

  1. How would you approach evaluating the current sales team and what is your process for developing a growth strategy to scale the team?
  2. What are the goals you would set for yourself in the 3 month and 1-year timeframes?

Thank you for taking the time to read this and I hope that this sounds like the opportunity for which you’ve been waiting.

More About The Role:
Backblaze’s Product Marketing Manager for Business Backup is an essential member of our Marketing team, reporting to the VP of Marketing.

The best PMM for Backblaze is a customer focused story teller. The role requires an understanding of both the Backblaze product offerings and the unique dynamics businesses face in backing up their data. We do not expect our PMM to be a storage expert. We do expect this person to be posses a deep understanding of the dynamics of marketing SaaS solutions to businesses.

Our PMM partners directly with our Business Backup sales team to shape our go to market strategy, deliver the appropriate content and collateral, and ultimately is an owner for hitting the forecast. One unique aspect of our Business Backup line is that over 50% of the revenue comes from “self-service” — inbound customers who get started on their own. As such, being a PMM at Backblaze is an opportunity to straddle “traditional” product marketing through supporting sales while also owning an direct-to-business “eCommerce” offering.

A Backblaze PMM:

  • Defines, creates, and delivers all content for the vertical. This person is the subject matter expert for that vertical for Backblaze and is capable of producing collateral for multiple mediums (email, web pages, blog posts, one-pagers)
  • Works collaboratively with Sales to design and execute go-to-market strategy
  • Delivers our revenue goals through sales enablement and direct response marketing

The Perfect PMM excels at:

  • Communication. Data storage can be complicated, but customers and co-workers want simple solutions.
  • Prioritization & Relentless Execution. Our business is growing fast. We need someone that can help set our strategic course, be process oriented, and then execute diligently and efficiently.
  • Collateral Creation. Case studies, emails, web pages, one pagers, presentations, Blog posts (to an audience of over 3 million readers.)
  • Learning. You’ll need to become an expert on our competitors. You’ll also have the opportunity to participate in ways you probably never had to do before. We value an “athlete” that’s willing and able to learn.
  • Being Evidence Driven. Numbers win. But when we don’t have numbers, informed guesses — customer profiles, feedback from Sales, market dynamics — take the day.
  • Working Cross Functionally. You will be the vertical expert for our organization. In that capacity, you will help inform the work of all of our departments.

The Ideal PMM background:

  • 3+ years of product marketing with a preference for SaaS experience.
  • Excellent time management and project prioritization skills
  • Demonstrated creative problem solving abilities
  • Ability to learn new markets, diagnose customer segments, and translate all that into actionable insights
  • Fluency with metrics: Saas sales funnel (MQL, SQL, etc), and eCommerce (CTR, visits, conversion)

Interested in Joining Our Team?
If this sounds like you, follow these steps:

  1. Send an email to jobscontact@backblaze.com with the position in the subject line.
  2. Include your resume and cover letter.
  3. Tell us a bit about your experience.

Amazon Neptune Generally Available

Post Syndicated from Randall Hunt original https://aws.amazon.com/blogs/aws/amazon-neptune-generally-available/

Amazon Neptune is now Generally Available in US East (N. Virginia), US East (Ohio), US West (Oregon), and EU (Ireland). Amazon Neptune is a fast, reliable, fully-managed graph database service that makes it easy to build and run applications that work with highly connected datasets. At the core of Neptune is a purpose-built, high-performance graph database engine optimized for storing billions of relationships and querying the graph with millisecond latencies. Neptune supports two popular graph models, Property Graph and RDF, through Apache TinkerPop Gremlin and SPARQL, allowing you to easily build queries that efficiently navigate highly connected datasets. Neptune can be used to power everything from recommendation engines and knowledge graphs to drug discovery and network security. Neptune is fully-managed with automatic minor version upgrades, backups, encryption, and fail-over. I wrote about Neptune in detail for AWS re:Invent last year and customers have been using the preview and providing great feedback that the team has used to prepare the service for GA.

Now that Amazon Neptune is generally available there are a few changes from the preview:

Launching an Amazon Neptune Cluster

Launching a Neptune cluster is as easy as navigating to the AWS Management Console and clicking create cluster. Of course you can also launch with CloudFormation, the CLI, or the SDKs.

You can monitor your cluster health and the health of individual instances through Amazon CloudWatch and the console.

Additional Resources

We’ve created two repos with some additional tools and examples here. You can expect continuous development on these repos as we add additional tools and examples.

  • Amazon Neptune Tools Repo
    This repo has a useful tool for converting GraphML files into Neptune compatible CSVs for bulk loading from S3.
  • Amazon Neptune Samples Repo
    This repo has a really cool example of building a collaborative filtering recommendation engine for video game preferences.

Purpose Built Databases

There’s an industry trend where we’re moving more and more onto purpose-built databases. Developers and businesses want to access their data in the format that makes the most sense for their applications. As cloud resources make transforming large datasets easier with tools like AWS Glue, we have a lot more options than we used to for accessing our data. With tools like Amazon Redshift, Amazon Athena, Amazon Aurora, Amazon DynamoDB, and more we get to choose the best database for the job or even enable entirely new use-cases. Amazon Neptune is perfect for workloads where the data is highly connected across data rich edges.

I’m really excited about graph databases and I see a huge number of applications. Looking for ideas of cool things to build? I’d love to build a web crawler in AWS Lambda that uses Neptune as the backing store. You could further enrich it by running Amazon Comprehend or Amazon Rekognition on the text and images found and creating a search engine on top of Neptune.

As always, feel free to reach out in the comments or on twitter to provide any feedback!

Monitoring your Amazon SNS message filtering activity with Amazon CloudWatch

Post Syndicated from Rachel Richardson original https://aws.amazon.com/blogs/compute/monitoring-your-amazon-sns-message-filtering-activity-with-amazon-cloudwatch/

This post is courtesy of Otavio Ferreira, Manager, Amazon SNS, AWS Messaging.

Amazon SNS message filtering provides a set of string and numeric matching operators that allow each subscription to receive only the messages of interest. Hence, SNS message filtering can simplify your pub/sub messaging architecture by offloading the message filtering logic from your subscriber systems, as well as the message routing logic from your publisher systems.

After you set the subscription attribute that defines a filter policy, the subscribing endpoint receives only the messages that carry attributes matching this filter policy. Other messages published to the topic are filtered out for this subscription. In this way, the native integration between SNS and Amazon CloudWatch provides visibility into the number of messages delivered, as well as the number of messages filtered out.

CloudWatch metrics are captured automatically for you. To get started with SNS message filtering, see Filtering Messages with Amazon SNS.

Message Filtering Metrics

The following six CloudWatch metrics are relevant to understanding your SNS message filtering activity:

  • NumberOfMessagesPublished – Inbound traffic to SNS. This metric tracks all the messages that have been published to the topic.
  • NumberOfNotificationsDelivered – Outbound traffic from SNS. This metric tracks all the messages that have been successfully delivered to endpoints subscribed to the topic. A delivery takes place either when the incoming message attributes match a subscription filter policy, or when the subscription has no filter policy at all, which results in a catch-all behavior.
  • NumberOfNotificationsFilteredOut – This metric tracks all the messages that were filtered out because they carried attributes that didn’t match the subscription filter policy.
  • NumberOfNotificationsFilteredOut-NoMessageAttributes – This metric tracks all the messages that were filtered out because they didn’t carry any attributes at all and, consequently, didn’t match the subscription filter policy.
  • NumberOfNotificationsFilteredOut-InvalidAttributes – This metric keeps track of messages that were filtered out because they carried invalid or malformed attributes and, thus, didn’t match the subscription filter policy.
  • NumberOfNotificationsFailed – This last metric tracks all the messages that failed to be delivered to subscribing endpoints, regardless of whether a filter policy had been set for the endpoint. This metric is emitted after the message delivery retry policy is exhausted, and SNS stops attempting to deliver the message. At that moment, the subscribing endpoint is likely no longer reachable. For example, the subscribing SQS queue or Lambda function has been deleted by its owner. You may want to closely monitor this metric to address message delivery issues quickly.

Message filtering graphs

Through the AWS Management Console, you can compose graphs to display your SNS message filtering activity. The graph shows the number of messages published, delivered, and filtered out within the timeframe you specify (1h, 3h, 12h, 1d, 3d, 1w, or custom).

SNS message filtering for CloudWatch Metrics

To compose an SNS message filtering graph with CloudWatch:

  1. Open the CloudWatch console.
  2. Choose Metrics, SNS, All Metrics, and Topic Metrics.
  3. Select all metrics to add to the graph, such as:
    • NumberOfMessagesPublished
    • NumberOfNotificationsDelivered
    • NumberOfNotificationsFilteredOut
  4. Choose Graphed metrics.
  5. In the Statistic column, switch from Average to Sum.
  6. Title your graph with a descriptive name, such as “SNS Message Filtering”

After you have your graph set up, you may want to copy the graph link for bookmarking, emailing, or sharing with co-workers. You may also want to add your graph to a CloudWatch dashboard for easy access in the future. Both actions are available to you on the Actions menu, which is found above the graph.

Summary

SNS message filtering defines how SNS topics behave in terms of message delivery. By using CloudWatch metrics, you gain visibility into the number of messages published, delivered, and filtered out. This enables you to validate the operation of filter policies and more easily troubleshoot during development phases.

SNS message filtering can be implemented easily with existing AWS SDKs by applying message and subscription attributes across all SNS supported protocols (Amazon SQS, AWS Lambda, HTTP, SMS, email, and mobile push). CloudWatch metrics for SNS message filtering is available now, in all AWS Regions.

Randomly generated, thermal-printed comics

Post Syndicated from Alex Bate original https://www.raspberrypi.org/blog/random-comic-strip-generation-vomit-comic-robot/

Python code creates curious, wordless comic strips at random, spewing them from the thermal printer mouth of a laser-cut body reminiscent of Disney Pixar’s WALL-E: meet the Vomit Comic Robot!

The age of the thermal printer!

Thermal printers allow you to instantly print photos, data, and text using a few lines of code, with no need for ink. More and more makers are using this handy, low-maintenance bit of kit for truly creative projects, from Pierre Muth’s tiny PolaPi-Zero camera to the sound-printing Waves project by Eunice Lee, Matthew Zhang, and Bomani McClendon (and our own Secret Santa Babbage).

Vomiting robots

Interaction designer and developer Cadin Batrack, whose background is in game design and interactivity, has built the Vomit Comic Robot, which creates “one-of-a-kind comics on demand by processing hand-drawn images through a custom software algorithm.”

The robot is made up of a Raspberry Pi 3, a USB thermal printer, and a handful of LEDs.

Comic Vomit Robot Cadin Batrack's Raspberry Pi comic-generating thermal printer machine

At the press of a button, Processing code selects one of a set of Cadin’s hand-drawn empty comic grids and then randomly picks images from a library to fill in the gaps.

Vomit Comic Robot Cadin Batrack's Raspberry Pi comic-generating thermal printer machine

Each image is associated with data that allows the code to fit it correctly into the available panels. Cadin says about the concept behing his build:

Although images are selected and placed randomly, the comic panel format suggests relationships between elements. Our minds create a story where there is none in an attempt to explain visuals created by a non-intelligent machine.

The Raspberry Pi saves the final image as a high-resolution PNG file (so that Cadin can sell prints on thick paper via Etsy), and a Python script sends it to be vomited up by the thermal printer.

Getting Rid of Your Mac? Here’s How to Securely Erase a Hard Drive or SSD

Post Syndicated from Roderick Bauer original https://www.backblaze.com/blog/how-to-wipe-a-mac-hard-drive/

erasing a hard drive and a solid state drive

What do I do with a Mac that still has personal data on it? Do I take out the disk drive and smash it? Do I sweep it with a really strong magnet? Is there a difference in how I handle a hard drive (HDD) versus a solid-state drive (SSD)? Well, taking a sledgehammer or projectile weapon to your old machine is certainly one way to make the data irretrievable, and it can be enormously cathartic as long as you follow appropriate safety and disposal protocols. But there are far less destructive ways to make sure your data is gone for good. Let me introduce you to secure erasing.

Which Type of Drive Do You Have?

Before we start, you need to know whether you have a HDD or a SSD. To find out, or at least to make sure, you click on the Apple menu and select “About this Mac.” Once there, select the “Storage” tab to see which type of drive is in your system.

The first example, below, shows a SATA Disk (HDD) in the system.

SATA HDD

In the next case, we see we have a Solid State SATA Drive (SSD), plus a Mac SuperDrive.

Mac storage dialog showing SSD

The third screen shot shows an SSD, as well. In this case it’s called “Flash Storage.”

Flash Storage

Make Sure You Have a Backup

Before you get started, you’ll want to make sure that any important data on your hard drive has moved somewhere else. OS X’s built-in Time Machine backup software is a good start, especially when paired with Backblaze. You can learn more about using Time Machine in our Mac Backup Guide.

With a local backup copy in hand and secure cloud storage, you know your data is always safe no matter what happens.

Once you’ve verified your data is backed up, roll up your sleeves and get to work. The key is OS X Recovery — a special part of the Mac operating system since OS X 10.7 “Lion.”

How to Wipe a Mac Hard Disk Drive (HDD)

NOTE: If you’re interested in wiping an SSD, see below.

    1. Make sure your Mac is turned off.
    2. Press the power button.
    3. Immediately hold down the command and R keys.
    4. Wait until the Apple logo appears.
    5. Select “Disk Utility” from the OS X Utilities list. Click Continue.
    6. Select the disk you’d like to erase by clicking on it in the sidebar.
    7. Click the Erase button.
    8. Click the Security Options button.
    9. The Security Options window includes a slider that enables you to determine how thoroughly you want to erase your hard drive.

There are four notches to that Security Options slider. “Fastest” is quick but insecure — data could potentially be rebuilt using a file recovery app. Moving that slider to the right introduces progressively more secure erasing. Disk Utility’s most secure level erases the information used to access the files on your disk, then writes zeroes across the disk surface seven times to help remove any trace of what was there. This setting conforms to the DoD 5220.22-M specification.

  1. Once you’ve selected the level of secure erasing you’re comfortable with, click the OK button.
  2. Click the Erase button to begin. Bear in mind that the more secure method you select, the longer it will take. The most secure methods can add hours to the process.

Once it’s done, the Mac’s hard drive will be clean as a whistle and ready for its next adventure: a fresh installation of OS X, being donated to a relative or a local charity, or just sent to an e-waste facility. Of course you can still drill a hole in your disk or smash it with a sledgehammer if it makes you happy, but now you know how to wipe the data from your old computer with much less ruckus.

The above instructions apply to older Macintoshes with HDDs. What do you do if you have an SSD?

Securely Erasing SSDs, and Why Not To

Most new Macs ship with solid state drives (SSDs). Only the iMac and Mac mini ship with regular hard drives anymore, and even those are available in pure SSD variants if you want.

If your Mac comes equipped with an SSD, Apple’s Disk Utility software won’t actually let you zero the hard drive.

Wait, what?

In a tech note posted to Apple’s own online knowledgebase, Apple explains that you don’t need to securely erase your Mac’s SSD:

With an SSD drive, Secure Erase and Erasing Free Space are not available in Disk Utility. These options are not needed for an SSD drive because a standard erase makes it difficult to recover data from an SSD.

In fact, some folks will tell you not to zero out the data on an SSD, since it can cause wear and tear on the memory cells that, over time, can affect its reliability. I don’t think that’s nearly as big an issue as it used to be — SSD reliability and longevity has improved.

If “Standard Erase” doesn’t quite make you feel comfortable that your data can’t be recovered, there are a couple of options.

FileVault Keeps Your Data Safe

One way to make sure that your SSD’s data remains secure is to use FileVault. FileVault is whole-disk encryption for the Mac. With FileVault engaged, you need a password to access the information on your hard drive. Without it, that data is encrypted.

There’s one potential downside of FileVault — if you lose your password or the encryption key, you’re screwed: You’re not getting your data back any time soon. Based on my experience working at a Mac repair shop, losing a FileVault key happens more frequently than it should.

When you first set up a new Mac, you’re given the option of turning FileVault on. If you don’t do it then, you can turn on FileVault at any time by clicking on your Mac’s System Preferences, clicking on Security & Privacy, and clicking on the FileVault tab. Be warned, however, that the initial encryption process can take hours, as will decryption if you ever need to turn FileVault off.

With FileVault turned on, you can restart your Mac into its Recovery System (by restarting the Mac while holding down the command and R keys) and erase the hard drive using Disk Utility, once you’ve unlocked it (by selecting the disk, clicking the File menu, and clicking Unlock). That deletes the FileVault key, which means any data on the drive is useless.

FileVault doesn’t impact the performance of most modern Macs, though I’d suggest only using it if your Mac has an SSD, not a conventional hard disk drive.

Securely Erasing Free Space on Your SSD

If you don’t want to take Apple’s word for it, if you’re not using FileVault, or if you just want to, there is a way to securely erase free space on your SSD. It’s a little more involved but it works.

Before we get into the nitty-gritty, let me state for the record that this really isn’t necessary to do, which is why Apple’s made it so hard to do. But if you’re set on it, you’ll need to use Apple’s Terminal app. Terminal provides you with command line interface access to the OS X operating system. Terminal lives in the Utilities folder, but you can access Terminal from the Mac’s Recovery System, as well. Once your Mac has booted into the Recovery partition, click the Utilities menu and select Terminal to launch it.

From a Terminal command line, type:

diskutil secureErase freespace VALUE /Volumes/DRIVE

That tells your Mac to securely erase the free space on your SSD. You’ll need to change VALUE to a number between 0 and 4. 0 is a single-pass run of zeroes; 1 is a single-pass run of random numbers; 2 is a 7-pass erase; 3 is a 35-pass erase; and 4 is a 3-pass erase. DRIVE should be changed to the name of your hard drive. To run a 7-pass erase of your SSD drive in “JohnB-Macbook”, you would enter the following:

diskutil secureErase freespace 2 /Volumes/JohnB-Macbook

And remember, if you used a space in the name of your Mac’s hard drive, you need to insert a leading backslash before the space. For example, to run a 35-pass erase on a hard drive called “Macintosh HD” you enter the following:

diskutil secureErase freespace 3 /Volumes/Macintosh\ HD

Something to remember is that the more extensive the erase procedure, the longer it will take.

[$] Killing processes that don’t want to die

Post Syndicated from jake original https://lwn.net/Articles/754980/rss

Suppose you have a program running on your system that you don’t quite
trust. Maybe it’s a program submitted by a student to an automated
grading system. Or maybe it’s a QEMU device model running in a Xen
control domain ("domain 0" or “dom0”), and you want to make sure
that even
if an attacker from a rogue virtual machine manages to take over the QEMU
process,
they can’t do any further harm. There are many things you want to do as far
as restricting its ability
to do mischief. But one thing in particular you probably want to do
is to be able to reliably kill the process once you think it should be
done. This turns out to be quite a bit more tricky than you’d think.

Project Floofball and more: Pi pet stuff

Post Syndicated from Janina Ander original https://www.raspberrypi.org/blog/project-floofball-pi-pet-stuff/

It’s a public holiday here today (yes, again). So, while we indulge in the traditional pastime of barbecuing stuff (ourselves, mainly), here’s a little trove of Pi projects that cater for our various furry friends.

Project Floofball

Nicole Horward created Project Floofball for her hamster, Harold. It’s an IoT hamster wheel that uses a Raspberry Pi and a magnetic door sensor to log how far Harold runs.

You can follow Harold’s runs in real time on his ThingSpeak channel, and you’ll find photos of the build on imgur. Nicole’s Python code, as well as her template for the laser-cut enclosure that houses the wiring and LCD display, are available on the hamster wheel’s GitHub repo.

A live-streaming pet feeder

JaganK3 used to work long hours that meant he couldn’t be there to feed his dog on time. He found that he couldn’t buy an automated feeder in India without paying a lot to import one, so he made one himself. It uses a Raspberry Pi to control a motor that turns a dispensing valve in a hopper full of dry food, giving his dog a portion of food at set times.

A transparent cylindrical hopper of dry dog food, with a motor that can turn a dispensing valve at the lower end. The motor is connected to a Raspberry Pi in a plastic case. Hopper, motor, Pi, and wiring are all mounted on a board on the wall.

He also added a web cam for live video streaming, because he could. Find out more in JaganK3’s Instructable for his pet feeder.

Shark laser cat toy

Sam Storino, meanwhile, is using a Raspberry Pi to control a laser-pointer cat toy with a goshdarned SHARK (which is kind of what I’d expect from the guy who made the steampunk-looking cat feeder a few weeks ago). The idea is to keep his cats interested and active within the confines of a compact city apartment.

If I were a cat, I would definitely be entirely happy with this. Find out more on Sam’s website.

And there’s more

Michel Parreno has written a series of articles to help you monitor and feed your pet with Raspberry Pi.

All of these makers are generous in acknowledging the tutorials and build logs that helped them with their projects. It’s lovely to see the Raspberry Pi and maker community working like this, and I bet their projects will inspire others too.

Now, if you’ll excuse me. I’m late for a barbecue.

Putin Asked to Investigate Damage Caused By Telegram Web-Blocking

Post Syndicated from Andy original https://torrentfreak.com/putin-asked-to-investigate-damage-caused-by-telegram-web-blocking-180526/

After a Moscow court gave the go-ahead for Telegram to be banned in Russia last month, the Internet became a battleground.

On the instructions of telecoms watchdog Roscomnadzor, ISPs across Russia tried to block Telegram by blackholing millions of IP addresses. The effect was both dramatic and pathetic. While Telegram remained stubbornly online, countless completely innocent services suffered outages as Roscomnadzor charged ahead with its mission.

Over the past several weeks, Roscomnadzor has gone some way to clean up the mess, partly by removing innocent Google and Amazon IP addresses from Russia’s blacklist. However, the collateral damage was so widespread it’s called into question the watchdog’s entire approach to web-blockades and whether they should be carried out at any cost.

This week, thanks to an annual report presented to President Vladimir Putin by business ombudsman Boris Titov, the matter looks set to be escalated. ‘The Book of Complaints and Suggestions of Russian Business’ contains comments from Internet ombudsman Dmitry Marinichev, who says that the Prosecutor General’s Office should launch an investigation into Roscomnadzor’s actions.

Marinichev said that when attempting to take down Telegram using aggressive technical means, Roscomnadzor relied upon “its own interpretation of court decisions” to provide guidance, TASS reports.

“When carrying out blockades of information resources, Roskomnadzor did not assess the related damage caused to them,” he said.

More than 15 million IP addresses were blocked, many of them with functions completely unrelated to the operations of Telegram. Marinichev said that the consequences were very real for those who suffered collateral damage.

“[The blocking led] to a temporary inaccessibility of Internet resources of a number of Russian enterprises in the Internet sector, including several banks and government information resources,” he reported.

In advice to the President, Marinichev suggests that the Prosecutor General’s Office should look into “the legality and validity of Roskomnadzor’s actions” which led to the “violation of availability of information resources of commercial companies” and “threatened the integrity, sustainability, and functioning of the unified telecommunications network of the Russian Federation and its critical information infrastructure.”

Early May, it was reported that in addition to various web services, around 50 VPN, proxy and anonymization platforms had been blocked for providing access to Telegram. In a May 22 report, that number had swelled to more than 80 although 10 were later unblocked after they stopped providing access to the messaging platform.

This week, Roscomnadzor has continued with efforts to block access to torrent and streaming platforms. In a new wave of action, the telecoms watchdog ordered ISPs to block at least 47 mirrors and proxies providing access to previously blocked sites.
