Announcing Coolest Projects North America

Post Syndicated from Courtney Lentz original https://www.raspberrypi.org/blog/coolest-projects-north-america/

The Raspberry Pi Foundation loves to celebrate people who use technology to solve problems and express themselves creatively, so we’re proud to expand the incredibly successful event Coolest Projects to North America. This free event will be held on Sunday 23 September 2018 at the Discovery Cube Orange County in Santa Ana, California.

What is Coolest Projects?

Coolest Projects is a world-leading showcase that empowers and inspires the next generation of digital creators, innovators, changemakers, and entrepreneurs. The event is both a competition and an exhibition to give young digital makers aged 7 to 17 a platform to celebrate their successes, creativity, and ingenuity.

In 2012, Coolest Projects was conceived as an opportunity for CoderDojo Ninjas to showcase their work and for supporters to acknowledge these achievements. Week after week, Ninjas would meet up to work diligently on their projects, hacks, and code; however, it can be difficult for them to see their long-term progress on a project when they’re concentrating on its details on a weekly basis. Coolest Projects became a dedicated time each year for Ninjas and supporters to reflect, celebrate, and share both the achievements and challenges of the maker’s journey.

Welcome Nathan – Our Solutions Engineer

Post Syndicated from Yev original https://www.backblaze.com/blog/welcome-nathan-our-solutions-engineer/

Backblaze is growing, and with it our need to cater to a lot of different use cases that our customers bring to us. We needed a Solutions Engineer to help out, and after a long search we’ve hired our first one! Lets learn a bit more about Nathan shall we?

What is your Backblaze Title?
Solutions Engineer. Our customers bring a thousand different use cases to both B1 and B2, and I’m here to help them figure out how best to make those use cases a reality. Also, any odd jobs that Nilay wants me to do.

Where are you originally from?
I am native to the San Francisco Bay Area, studying mathematics at UC Santa Cruz, and then computer science at California University of Hayward (which has since renamed itself California University of the East Hills. I observe that it’s still in Hayward).

What attracted you to Backblaze?
As a stable, growing company with huge growth and even bigger potential, the business model is attractive, and the team is outstanding. Add to that the strong commitment to transparency, and it’s a hard company to resist. We can store – and restore – data while offering superior reliability at an economic advantage to do-it-yourself, and that’s a great place to be.

What do you expect to learn while being at Backblaze?
Everything I need to, but principally how our customers choose to interact with web storage. Storage isn’t a solution per se, but it’s an important component of any persistent solution. I’m looking forward to working with all the different concepts our customers have to make use of storage.

Where else have you worked?
All sorts of places, but I’ll admit publicly to EMC, Gemalto, and my own little (failed, alas) startup, IC2N. I worked with low-level document imaging.

Where did you go to school?
UC Santa Cruz, BA Mathematics CU Hayward, Master of Science in Computer Science.

What’s your dream job?
Sipping tea in the California redwood forest. However, solutions engineer at Backblaze is a good second choice!

Favorite place you’ve traveled?
Ashland, Oregon, for the Oregon Shakespeare Festival and the marble caves (most caves form from limestone).

Favorite hobby?
Theater. Pathfinder. Writing. Baking cookies and cakes.

Of what achievement are you most proud?
Marrying the most wonderful man in the world.

Star Trek or Star Wars?
Star Trek’s utopian science fiction vision of humanity and science resonates a lot more strongly with me than the dystopian science fantasy of Star Wars.

Coke or Pepsi?
Neither. I’d much rather have a cup of jasmine tea.

Favorite food?
It varies, but I love Indian and Thai cuisine. Truly excellent Italian food is marvelous – wood fired pizza, if I had to pick only one, but the world would be a boring place with a single favorite food.

Why do you like certain things?
If I knew that, I’d be in marketing.

Anything else you’d like you’d like to tell us?
If you haven’t already encountered the amazing authors Patricia McKillip and Lois McMasters Bujold – go encounter them. Be happy.

There’s nothing wrong with a nice cup of tea and a long game of Pathfinder. Sign us up! Welcome to the team Nathan!

Grumpy Cat Wins $710,000 From Copyright Infringing Coffee Maker

Post Syndicated from Ernesto original https://torrentfreak.com/grumpy-cat-wins-710000-copyright-infringing-coffee-maker-180125/

grumpcatThere are dozens of celebrity cats on the Internet, but Grumpy Cat probably tops them all.

The cat’s owners have made millions thanks to their pet’s unique facial expression, which turned her into an overnight Internet star.

Part of this revenue comes from successful merchandise lines, including the Grumpy Cat “Grumppuccino” iced coffee beverage, sold by the California company Grenade Beverage.

The company licensed the copyright and trademarks to sell the iced coffee but is otherwise not affiliated with the cat and its owners. Initially, this partnership went well, but after the coffee maker started to sell other “Grumpy Cat” products, things turned bad.

The cat’s owners, incorporated as Grumpy Cat LLC, took the matter to court with demands for the coffee maker to stop infringing associated copyrights and trademarks.

“Without authorization, Defendants […] have extensively and repeatedly exploited the Grumpy Cat Copyrights and the Grumpy Cat Trademarks,” the complaint read.

After two years the case went before a jury this week where, Courthouse News reports, the cat itself also made an appearance.

The eight-person jury in Santa Ana, California sided with the cat’s owner and awarded the company $710,000 in copyright and trademark infringement damages, as well as a symbolic $1 for contract breach.

According to court documents, the majority of the damages have to be paid by Grumpy Beverage, but the company’s owner Paul Sandford is also held personally liable for $60,000.

The verdict is good news for Grumpy Cat and its owner, and according to their attorney, they are happy with the outcome.

“Grumpy Cat feels vindicated and feels the jury reached a just verdict,” Grumpy Cat’s lawyer David Jonelis said, describing it as “a complete victory.”

A copy of the verdict form is available here (pdf).

Fake Santa Surveillance Camera

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

Reka makes a “decorative Santa cam,” meaning that it’s not a real camera. Instead, it just gets children used to being under constant surveillance.

Our Santa Cam has a cute Father Christmas and mistletoe design, and a red, flashing LED light which will make the most logical kids suspend their disbelief and start to believe!

Thank you for my new Raspberry Pi, Santa! What next?

Post Syndicated from Alex Bate original https://www.raspberrypi.org/blog/thank-you-for-my-new-raspberry-pi-santa-what-next/

Note: the Pi Towers team have peeled away from their desks to spend time with their families over the festive season, and this blog will be quiet for a while as a result. We’ll be back in the New Year with a bushel of amazing projects, awesome resources, and much merriment and fun times. Happy holidays to all!

Now back to the matter at hand. Your brand new Christmas Raspberry Pi.

Your new Raspberry Pi

Did you wake up this morning to find a new Raspberry Pi under the tree? Congratulations, and welcome to the Raspberry Pi community! You’re one of us now, and we’re happy to have you on board.

But what if you’ve never seen a Raspberry Pi before? What are you supposed to do with it? What’s all the fuss about, and why does your new computer look so naked?

Setting up your Raspberry Pi

Are you comfy? Good. Then let us begin.

Download our free operating system

First of all, you need to make sure you have an operating system on your micro SD card: we suggest Raspbian, the Raspberry Pi Foundation’s official supported operating system. If your Pi is part of a starter kit, you might find that it comes with a micro SD card that already has Raspbian preinstalled. If not, you can download Raspbian for free from our website.

An easy way to get Raspbian onto your SD card is to use a free tool called Etcher. Watch The MagPi’s Lucy Hattersley show you what you need to do. You can also use NOOBS to install Raspbian on your SD card, and our Getting Started guide explains how to do that.

Plug it in and turn it on

Your new Raspberry Pi 3 comes with four USB ports and an HDMI port. These allow you to plug in a keyboard, a mouse, and a television or monitor. If you have a Raspberry Pi Zero, you may need adapters to connect your devices to its micro USB and micro HDMI ports. Both the Raspberry Pi 3 and the Raspberry Pi Zero W have onboard wireless LAN, so you can connect to your home network, and you can also plug an Ethernet cable into the Pi 3.

Make sure to plug the power cable in last. There’s no ‘on’ switch, so your Pi will turn on as soon as you connect the power. Raspberry Pi uses a micro USB power supply, so you can use a phone charger if you didn’t receive one as part of a kit.

Learn with our free projects

If you’ve never used a Raspberry Pi before, or you’re new to the world of coding, the best place to start is our projects site. It’s packed with free projects that will guide you through the basics of coding and digital making. You can create projects right on your screen using Scratch and Python, connect a speaker to make music with Sonic Pi, and upgrade your skills to physical making using items from around your house.

Here’s James to show you how to build a whoopee cushion using a Raspberry Pi, paper plates, tin foil and a sponge:

Whoopee cushion PRANK with a Raspberry Pi: HOW-TO

Explore the world of Raspberry Pi physical computing with our free FutureLearn courses: http://rpf.io/futurelearn Free make your own Whoopi Cushion resource: http://rpf.io/whoopi For more information on Raspberry Pi and the charitable work of the Raspberry Pi Foundation, including Code Club and CoderDojo, visit http://rpf.io Our resources are free to use in schools, clubs, at home and at events.

Diving deeper

You’ve plundered our projects, you’ve successfully rigged every chair in the house to make rude noises, and now you want to dive deeper into digital making. Good! While you’re digesting your Christmas dinner, take a moment to skim through the Raspberry Pi blog for inspiration. You’ll find projects from across our worldwide community, with everything from home automation projects and retrofit upgrades, to robots, gaming systems, and cameras.

You’ll also find bucketloads of ideas in The MagPi magazine, the official monthly Raspberry Pi publication, available in both print and digital format. You can download every issue for free. If you subscribe, you’ll get a Raspberry Pi Zero W to add to your new collection. HackSpace magazine is another fantastic place to turn for Raspberry Pi projects, along with other maker projects and tutorials.

And, of course, simply typing “Raspberry Pi projects” into your preferred search engine will find thousands of ideas. Sites like Hackster, Hackaday, Instructables, Pimoroni, and Adafruit all have plenty of fab Raspberry Pi tutorials that they’ve devised themselves and that community members like you have created.

And finally

If you make something marvellous with your new Raspberry Pi – and we know you will – don’t forget to share it with us! Our Twitter, Facebook, Instagram and Google+ accounts are brimming with chatter, projects, and events. And our forums are a great place to visit if you have questions about your Raspberry Pi or if you need some help.

It’s good to get together with like-minded folks, so check out the growing Raspberry Jam movement. Raspberry Jams are community-run events where makers and enthusiasts can meet other makers, show off their projects, and join in with workshops and discussions. Find your nearest Jam here.

Have a great festive holiday and welcome to the community. We’ll see you in 2018!

The deep learning Santa/Not Santa detector

Post Syndicated from Alex Bate original https://www.raspberrypi.org/blog/deep-learning-santa-detector/

Did you see Mommy kissing Santa Claus? Or was it simply an imposter? The Not Santa detector is here to help solve the mystery once and for all.

Building a “Not Santa” detector on the Raspberry Pi using deep learning, Keras, and Python

The video is a demo of my “Not Santa” detector that I deployed to the Raspberry Pi. I trained the detector using deep learning, Keras, and Python. You can find the full source code and tutorial here: https://www.pyimagesearch.com/2017/12/18/keras-deep-learning-raspberry-pi/

Ho-ho-how does it work?

Note: Adrian Rosebrock is not Santa. But he does a good enough impression of the jolly old fellow that his disguise can fool a Raspberry Pi into thinking otherwise.

Raspberry Pi 'Not Santa' detector

We jest, but has anyone seen Adrian and Santa in the same room together?
Image c/o Adrian Rosebrock

But how is the Raspberry Pi able to detect the Santa-ness or Not-Santa-ness of people who walk into the frame?

Two words: deep learning

If you’re not sure what deep learning is, you’re not alone. It’s a hefty topic, and one that Adrian has written a book about, so I grilled him for a bluffers’ guide. In his words, deep learning is:

…a subfield of machine learning, which is, in turn a subfield of artificial intelligence (AI). While AI embodies a large, diverse set of techniques and algorithms related to automatic reasoning (inference, planning, heuristics, etc), the machine learning subfields are specifically interested in pattern recognition and learning from data.

Artificial Neural Networks (ANNs) are a class of machine learning algorithms that can learn from data. We have been using ANNs successfully for over 60 years, but something special happened in the past 5 years — (1) we’ve been able to accumulate massive datasets, orders of magnitude larger than previous datasets, and (2) we have access to specialized hardware to train networks faster (i.e., GPUs).

Given these large datasets and specialized hardware, deeper neural networks can be trained, leading to the term “deep learning”.

So now we have a bird’s-eye view of deep learning, how does the detector detect?

Cameras and twinkly lights

Adrian used a model he had trained on two datasets to detect whether or not an image contains Santa. He deployed the Not Santa detector code to a Raspberry Pi, then attached a camera, speakers, and The Pi Hut’s 3D Xmas Tree.

Raspberry Pi 'Not Santa' detector

Components for Santa detection
Image c/o Adrian Rosebrock

The camera captures footage of Santa in the wild, while the Christmas tree add-on provides a twinkly notification, accompanied by a resonant ho, ho, ho from the speakers.

A deeper deep dive into deep learning

A full breakdown of the project and the workings of the Not Santa detector can be found on Adrian’s blog, PyImageSearch, which includes links to other deep learning and image classification tutorials using TensorFlow and Keras. It’s an excellent place to start if you’d like to understand more about deep learning.

Build your own Santa detector

Santa might catch on to Adrian’s clever detector and start avoiding the camera, and for that eventuality, we have our own Santa detector. It uses motion detection to notify you of his presence (and your presents!).

Raspberry Pi Santa detector

Check out our Santa Detector resource here and use a passive infrared sensor, Raspberry Pi, and Scratch to catch the big man in action.

All the lights, all of the twinkly lights

Post Syndicated from Alex Bate original https://www.raspberrypi.org/blog/all-of-the-lights/

Twinkly lights are to Christmas what pumpkins are to Halloween. And when you add a Raspberry Pi to your light show, the result instantly goes from “Meh, yeah.” to “OMG, wow!”

Here are some cool light-based Christmas projects to inspire you this weekend.

Raspberry Pi Christmas Lights

App-based light control

Christmas Tree Lights Demo

Project Code – https://github.com/eidolonFIRE/Christmas-Lights Raspberry Pi A+ ws2812b – https://smile.amazon.com/gp/product/B01H04YAIQ/ref=od_aui_detailpages00?ie=UTF8&psc=1 200w 5V supply – https://smile.amazon.com/gp/product/B01LZRIWZD/ref=od_aui_detailpages01?ie=UTF8&psc=1

In his Christmas lights project, Caleb Johnson uses an app as a control panel to switch between predefined displays. The full code is available on his GitHub, and it connects a Raspberry Pi A+ to a strip of programmable LEDs that change their pattern at the touch of a phone screen.

What’s great about this project, aside from the simplicity of its design, is the scope for extending it. Why not share the app with friends and family, allowing them to control your lights remotely? Or link the lights to social media so they are triggered by a specific hashtag, like in Alex Ellis’ #cheerlights project below.

Worldwide holiday #cheerlights

Holiday lights hack – 1$ Snowman + Raspberry Pi

Here we have a smart holiday light which will only run when it detects your presence in the room through a passive infrared PIR sensor. I’ve used hot glue for the fixings and an 8-LED NeoPixel strip connected to port 18.

Cheerlights, an online service created by Hans Scharler, allows makers to incorporate hashtag-controlled lighting into the projects. By tweeting the hashtag #cheerlights, followed by a colour, you can control a network of lights so that they are all displaying the same colour.

For his holiday light hack using Cheerlights, Alex incorporated the Pimoroni Blinkt! and a collection of cheap Christmas decorations to create cute light-up ornaments for the festive season.

To make your own, check out Alex’s blog post, and head to your local £1/$1 store for hackable decor. You could even link your Christmas tree and the trees of your family, syncing them all in one glorious, Santa-pleasing spectacular.

Outdoor decorations

DIY musical Xmas lights for beginners with raspberry pi

With just a few bucks of extra material, I walk you through converting your regular Christmas lights into a whole-house light show. The goal here is to go from scratch. Although this guide is intended for people who don’t know how to use linux at all and those who do alike, the focus is for people for whom linux and the raspberry pi are a complete mystery.

Looking to outdo your neighbours with your Christmas light show this year? YouTuber Makin’Things has created a beginners guide to setting up a Raspberry Pi–based musical light show for your facade, complete with information on soldering, wiring, and coding.

Once you’ve wrapped your house in metres and metres of lights and boosted your speakers so they can be heard for miles around, why not incorporate #cheerlights to make your outdoor decor interactive?

Still not enough? How about controlling your lights using a drum kit? Christian Kratky’s MIDI-Based Christmas Lights Animation system (or as I like to call it, House Rock) does exactly that.

Any more?

We know these projects are just the tip of the iceberg when it comes to the Raspberry Pi–powered Christmas projects out there, and as always, we’d love you to share yours with us. So post a link in the comments below, or tag us on social media when posting your build photos, videos, and/or blog links. ‘Tis the season for sharing after all.

The Pi Towers Secret Santa Babbage

Post Syndicated from Mark Calleja original https://www.raspberrypi.org/blog/secret-santa-babbage/

Tired of pulling names out of a hat for office Secret Santa? Upgrade your festive tradition with a Raspberry Pi, thermal printer, and everybody’s favourite microcomputer mascot, Babbage Bear.

Raspberry Pi Babbage Bear Secret Santa

The name’s Santa. Secret Santa.

It’s that time of year again, when the cosiness gets turned up to 11 and everyone starts thinking about jolly fat men, reindeer, toys, and benevolent home invasion. At Raspberry Pi, we’re running a Secret Santa pool: everyone buys a gift for someone else in the office. Obviously, the person you buy for has to be picked in secret and at random, or the whole thing wouldn’t work. With that in mind, I created Secret Santa Babbage to do the somewhat mundane task of choosing gift recipients. This could’ve just been done with some names in a hat, but we’re Raspberry Pi! If we don’t make a Python-based Babbage robot wearing a jaunty hat and programmed to spread Christmas cheer, who will?

Secret Santa Babbage

Ho ho ho!

Mecha-Babbage Xmas shenanigans

The script the robot runs is pretty basic: a list of names entered as comma-separated strings is shuffled at the press of a GPIO button, then a name is popped off the end and stored as a variable. The name is matched to a photo of the person stored on the Raspberry Pi, and a thermal printer pinched from Alex’s super awesome PastyCam (blog post forthcoming, maybe) prints out the picture and name of the person you will need to shower with gifts at the Christmas party. (Well, OK — with one gift. No more than five quid’s worth. Nothing untoward.) There’s also a redo function, just in case you pick yourself: press another button and the last picked name — still stored as a variable — is appended to the list again, which is shuffled once more, and a new name is popped off the end.

Secret Santa Babbage prototyping

Prototyping!

As the build was a bit of a rush job undertaken at the request of our ‘Director of Vibe’ Emily, there are a few things I’d like to improve about this functionality that I didn’t get around to — more on that later. To add some extra holiday spirit to the project at the last minute, I used Pygame to play a WAV file of Santa’s jolly laugh while Babbage chooses a name for you. The file is included in the GitHub repo along with everything else, because ‘tis the season, etc., etc.

Secret Santa Babbage prototyping

Editor’s note: Considering these desk adornments, Mark’s Secret Santa gift-giver has a lot to go on.

Writing the code for Xmas Mecha-Babbage was fairly straightforward, though it uses some tricky bits for managing the thermal printer. You’ll need to install the drivers to make it go, as well as the CUPS package for managing the print hosting. You can find instructions for these things here, thanks to the wonderful Adafruit crew. Also, for reasons I couldn’t fathom, this will all only work on a Pi 2 and not a Pi 3, as there are some compatibility issues with the thermal printer otherwise. (I also tested the script on a Pi Zero W…no dice.)

Building a Christmassy throne

The hardest (well, fiddliest) parts of making the whole build were constructing the throne and wiring the bear. Using MakerCase, Inkscape, a bit of ingenuity, and a laser cutter, I was able to rig up a Christmassy plywood throne which has a hole through the seat so I could run the wires down from Babbage and to the Pi inside. I finished the throne by rubbing a couple of fingers of beeswax into it; as well as making the wood shine just a little bit and protecting it against getting wet, this had the added bonus of making it smell awesome.

Secret Santa Babbage inside

Next year’s iteration will be mulled wine–scented.

I next soldered two LEDs to some lengths of wire, and then ran the wires through holes at the top of the throne and down the back along a small channel I had carved with a narrow chisel to connect them to the Pi’s GPIO pins. The green LED will remain on as long as Babbage is running his program, and the red one will light up while he is processing your request. Once the red LED goes off again, the next person can have a go. I also laser-cut a final piece of wood to overlay the back of Babbage’s Xmas throne and cover the wiring a bit.

Creating a Xmas cyborg bear

Taking two 6 mm tactile buttons, I clipped the spiky metal legs off one side of each (the buttons were going into a stuffed christmas toy, after all) and soldered a length of wire to each of the remaining legs. Next, I made a small incision into Babbage with my trusty Swiss army knife (in a place that actually made me cringe a little) and fed the buttons up into his paws. At some point in this process I was standing in the office wrestling with the bear and muttering to myself, which elicited some very strange looks from my colleagues.

Poor Babbage…

One thing to note here is to make sure the wires remain attached at the solder points while you push them up into Babbage’s paws. The first time I tried it, I snapped one of my connections and had to start again. It helped to remove some stuffing like a tunnel and then replace it afterward. Moreover, you can use your fingertip to support the joints as you poke the wire in. Finally, a couple of squirts of hot glue to keep Babbage’s furry cheeks firmly on the seat, and done!

Next year: Game of Thrones–inspired candy cane throne

The Secret Santa Babbage masterpiece

The whole build process was the perfect holiday mix of cheerful and macabre, and while getting the thermal printer to work was a little time-consuming, the finished product definitely raised some smiles around the office and added a bit of interesting digital flavour to a staid office tradition. And it also helped people who are new to the office or from other branches of the Foundation to know for whom they will be buying a gift.

Secret Santa Babbage

Ready to dispense Christmas cheer!

There are a few ways in which I’ll polish this project before next year, such as having the script write the names to external text files to create a record that will persist in case of a reboot, and maybe having Secret Santa Babbage play you a random Christmas carol when you squeeze his paw instead of just laughing merrily every time. (I also thought about adding electric shocks for those people who are on the naughty list, but HR said no. Bah, humbug!)

Make your own

The code and laser cut plans for the whole build are available here. If you plan to make your own, let us know which stuffed toy you will be turning into a Secret Santa cyborg! And if you’ve been working on any other Christmas-themed Raspberry Pi projects, we’d like to see those too, so tag us on social media to share the festive maker cheer.

In the immortal words of Noddy Holder: “it’s Christmaaaaaaasssss!” Well, maybe it isn’t quite Christmas yet, but since the shops have been playing Mariah Carey on a loop since the last pumpkin lantern hit the bargain bin, you’re hopefully well prepared.

To get you in the mood with some festive fun, we’ve put together a selection of seasonal free resources for you. Each project has a difficulty level in line with our Digital Making Curriculum, so you can check which might suit you best. Why not try them out at your local Raspberry Jam, CoderDojo, or Code Club, at school, or even on a cold day at home with a big mug of hot chocolate?

Jazzy jumpers

Code a carol (Developer level): Have you ever noticed how much repetition there is in carols and other songs? This resource teaches you how to break down the Twelve days of Christmas tune into its component parts and code it up in Sonic Pi the lazy way: get the computer to do all the repetition for you!

No musical knowledge required — just follow our lead, and you’ll have yourself a rocking doorbell tune in no time!

Naughty and nice

A cartoon of Santa judging people by their tweets - Raspberry Pi Christmas Resources

Naughty and nice (Maker level): Have you been naughty or nice? Find out by using sentiment analysis on your tweets to see what sort of things you’ve been talking about throughout the year. For added fun, why not use your program on the Twitter account of your sibling/spouse/arch nemesis and report their level of naughtiness to Santa with an @ mention?

raspberry_pi is 65.5 percent NICE, with an accuracy of 0.9046692607003891

It’s Christmaaaaaasssss

With the festive season just around the corner, it’s time to get started on your Christmas projects! Whether you’re planning to run your Christmas lights via a phone app, install a home assistant inside an Elf on a Shelf, or work through our Christmas resources, we would like to see what you make. So do share your festive builds with us on social media, or by posting links in the comments.

[$] Finding driver bugs with DR. CHECKER

Post Syndicated from jake original https://lwn.net/Articles/733056/rss

Drivers are a consistent source of kernel bugs, at least partly due to less
review, but also because drivers are typically harder for tools to
analyze. A team from the University of California, Santa Barbara has set
out to change that with a static-analysis tool called DR. CHECKER. In a paper
[PDF]
presented at the recent 26th USENIX
Security Symposium
, the team introduced the tool and the results of
running it on nine production Linux kernels. Those results were rather
encouraging:
it
correctly identified 158 critical zero-day
bugs with an overall precision of 78%

Hard Drive Stats for Q2 2017

Post Syndicated from Andy Klein original https://www.backblaze.com/blog/hard-drive-failure-stats-q2-2017/

Backblaze Drive Stats Q2 2017

In this update, we’ll review the Q2 2017 and lifetime hard drive failure rates for all our current drive models. We also look at how our drive migration strategy is changing the drives we use and we’ll check in on our enterprise class drives to see how they are doing. Along the way we’ll share our observations and insights and as always we welcome your comments and critiques.

Since our last report for Q1 2017, we have added 635 additional hard drives to bring us to the 83,151 drives we’ll focus on. In Q1 we added over 10,000 new drives to the mix, so adding just 635 in Q2 seems “odd.” In fact, we added 4,921 new drives and retired 4,286 old drives as we migrated from lower density drives to higher density drives. We cover more about migrations later on, but first let’s look at the Q2 quarterly stats.

Hard Drive Stats for Q2 2017

We’ll begin our review by looking at the statistics for the period of April 1, 2017 through June 30, 2017 (Q2 2017). This table includes 17 different 3 ½” drive models that were operational during the indicated period, ranging in size from 3 to 8 TB.

Quarterly Hard Drive Failure Rates for Q2 2017

When looking at the quarterly numbers, remember to look for those drives with at least 50,000 drive hours for the quarter. That works out to about 550 drives running the entire quarter. That’s a good sample size. If the sample size is below that, the failure rates can be skewed based on a small change in the number of drive failures.

As noted previously, we use the quarterly numbers to look for trends. So this time we’ve included a trend indicator in the table. The “Q2Q Trend” column is short for quarter-to-quarter trend, i.e. last quarter to this quarter. We can add, change, or delete trend columns depending on community interest. Let us know what you think in the comments.

Good Migrations

In Q2 we continued with our data migration program. For us, a drive migration means we intentionally remove a good drive from service and replace it with another drive. Drives that are removed via migrations are not counted as failed. Once they are removed they stop accumulating drive hours and other stats in our system.

There are three primary drivers for our migration program.

  1. Increase Storage Density – For example, in Q3 we replaced 3 TB drives with 8 TB drives, more than doubling the amount of storage in a given Storage Pod for the same footprint. The cost of electricity was nominally more with the 8 TB drives, but the increase in density more than offset the additional cost. For those interested you can read more about the cost of cloud storage here.
  2. Backblaze Vaults – Our Vault architecture has proven to be more cost effective over the past two years than using stand-alone Storage Pods. A major goal of the migration program is to have the entire Backblaze cloud deployed on the highly efficient and resilient Backblaze Vault architecture.
  3. Balancing the Load – With our Phoenix data center online and accepting data, we have migrated some systems to the Phoenix DC. Don’t worry, we didn’t put your data on a truck and drive it to Phoenix. We simply built new systems there and transferred the data from our Northern California DC. In the process, we are gaining valuable insights as we move towards being able to replicate data between the two data centers.
During Q2 we migrated nearly 30 Petabytes of data.

During Q2 we migrated the data on 155 systems, giving nearly 30 petabytes of data a new, more durable, place to call home. There are still 644 individual Storage Pods (Storage Pod Classics, as we call them) left to migrate to the Backblaze Vault architecture.

Just in case you don’t know, a Backblaze Vault is a logical collection of 20 beefy Storage Pods (not Classics). Using our own Reed-Solomon erasure coding library, data is spread out across the 20 Pods into 17 data shards and 3 parity shards. The data and parity shards of each arriving data blob can be stored on different Storage Pods in a given Backblaze Vault.

Lifetime Hard Drive Failure Rates for Current Drives

The table below shows the failure rates for the hard drive models we had in service as of June 30, 2017. This is over the period beginning in April 2013 and ending June 30, 2017. If you are interested in the hard drive failure rates for all the hard drives we’ve used over the years, please refer to our 2016 hard drive review.

Cumulative Hard Drive Failure Rates

Enterprise vs Consumer Drives

We added 3,595 enterprise class 8 TB drives in Q2 bringing our total to 6,054 drives. You may be tempted to compare the failure rates of the 8 TB enterprise drive (model: ST8000NM005) to the consumer 8 TB drive (model: ST8000DM002), and conclude the enterprise drives fail at a higher rate. Let’s not jump to that conclusion yet, as the average operational age of the enterprise drives is only 2.11 months.

There are some insights we can gain from the current data. The enterprise drives have 363,282 drives hours and an annualized failure rate of 1.61%. If we look back at our data, we find that as of Q3 2016, the 8 TB consumer drives had 422,263 drive hours with an annualized failure rate of 1.60%. That means that when both drive models had a similar number of drive hours, they had nearly the same annualized failure rate. There are no conclusions to be made here, but the observation is worth considering as we gather data for our comparison.

Next quarter, we should have enough data to compare the 8 TB drives, but by then the 8TB drives could be “antiques.” In the next week or so, we’ll be installing 12 TB hard drives in a Backblaze Vault. Each 60-drive Storage Pod in the Vault would have 720 TB of storage available and a 20-pod Backblaze Vault would have 14.4 petabytes of raw storage.

Better Late Than Never

Sorry for being a bit late with the hard drive stats report this quarter. We were ready to go last week, then this happened. Some folks here thought that was more important than our Q2 Hard Drive Stats. Go figure.

Drive Stats at the Storage Developers Conference

We will be presenting at the Storage Developers Conference in Santa Clara on Monday September 11th at 8:30am. We’ll be reviewing our drive stats along with some interesting observations from the SMART stats we also collect. The conference is the leading event for technical discussions and education on the latest storage technologies and standards. Come join us.

The Data For This Review

If you are interested in the data from the two tables in this review, you can download an Excel spreadsheet containing the two tables. Note: the domain for this download will be f001.backblazeb2.com.

You also can download the entire data set we use for these reports from our Hard Drive Test Data page. You can download and use this data for free for your own purposes. All we ask are three things: 1) you cite Backblaze as the source if you use the data, 2) you accept that you are solely responsible for how you use the data, and 3) you do not sell this data to anyone. It is free.

Good luck, and let us know if you find anything interesting.

Affordable Raspberry Pi 3D Body Scanner

Post Syndicated from Alex Bate original https://www.raspberrypi.org/blog/affordable-raspberry-pi-3d-body-scanner/

With a £1000 grant from Santander, Poppy Mosbacher set out to build a full-body 3D body scanner with the intention of creating an affordable setup for makespaces and similar community groups.

First Scan from DIY Raspberry Pi Scanner

Head and Shoulders Scan with 29 Raspberry Pi Cameras

Uses for full-body 3D scanning

Poppy herself wanted to use the scanner in her work as a fashion designer. With the help of 3D scans of her models, she would be able to create custom cardboard dressmakers dummy to ensure her designs fit perfectly. This is a brilliant way of incorporating digital tech into another industry – and it’s not the only application for this sort of build. Growing numbers of businesses use 3D body scanning, for example the stores around the world where customers can 3D scan and print themselves as action-figure-sized replicas.

Print your own family right on the high street!

We’ve also seen the same technology used in video games for more immersive virtual reality. Moreover, there are various uses for it in healthcare and fitness, such as monitoring the effect of exercise regimes or physiotherapy on body shape or posture.

Within a makespace environment, a 3D body scanner opens the door to including new groups of people in community make projects: imagine 3D printing miniatures of a theatrical cast to allow more realistic blocking of stage productions and better set design, or annually sending grandparents a print of their grandchild so they can compare the child’s year-on-year growth in a hands-on way.

The Germany-based clothing business Outfittery uses full body scanners to take the stress out of finding clothes that fits well.

As cheesy as it sounds, the only limit for the use of 3D scanning is your imagination…and maybe storage space for miniature prints.

Poppy’s Raspberry Pi 3D Body Scanner

For her build, Poppy acquired 27 Raspberry Pi Zeros and 27 Raspberry Pi Camera Modules. With various other components, some 3D-printed or made of cardboard, Poppy got to work. She was helped by members of Build Brighton and by her friend Arthur Guy, who also wrote the code for the scanner.

Raspberry Pi 3D Body Scanner

The Pi Zeros run Raspbian Lite, and are connected to a main server running a node application. Each is fitted into its own laser-cut cardboard case, and secured to a structure of cardboard tubing and 3D-printed connectors.

Raspberry Pi 3D Body Scanner

In the finished build, the person to be scanned stands within the centre of the structure, and the press of a button sends the signal for all Pis to take a photo. The images are sent back to the server, and processed through Autocade ReMake, a freemium software available for the PC (Poppy discovered part-way through the project that the Mac version has recently lost support).

Build your own

Obviously there’s a lot more to the process of building this full-body 3D scanner than what I’ve reported in these few paragraphs. And since it was Poppy’s goal to make a readily available and affordable scanner that anyone can recreate, she’s provided all the instructions and code for it on her Instructables page.

Projects like this, in which people use the Raspberry Pi to create affordable and interesting tech for communities, are exactly the type of thing we love to see. Always make sure to share your Pi-based projects with us on social media, so we can boost their visibility!

If you’re a member of a makespace, run a workshop in a school or club, or simply love to tinker and create, this build could be the perfect addition to your workshop. And if you recreate Poppy’s scanner, or build something similar, we’d love to see the results in the comments below.

Lawyer Says He Was Deceived Into BitTorrent Copyright Trolling Scheme

Post Syndicated from Andy original https://torrentfreak.com/lawyer-says-he-was-deceived-into-bittorrent-copyright-trolling-scheme-170807/

For more than a decade, companies around the world have been trying to turn piracy into profit. For many this has meant the development of “copyright trolling” schemes, in which alleged pirates are monitored online and then pressured into cash settlements.

The shadowy nature of this global business means that its true scale will never be known but due to the controversial activities of some of the larger players, it’s occasionally possible to take a peek inside their operations. One such opportunity has just raised its head.

According to a lawsuit filed in California, James Davis is an attorney licensed in Oregon and California. Until two years ago, he was largely focused on immigration law. However, during March 2015, Davis says he was approached by an old classmate with an opportunity to get involved in a new line of business.

That classmate was Oregon lawyer Carl Crowell, who over the past several years has been deeply involved in copyright-trolling cases, including a deluge of Dallas Buyers Club and London Has Fallen litigation. He envisioned a place for Davis in the business.

Davis seemed to find the proposals attractive and became seriously involved in the operation, filing 58 cases on behalf of the companies involved. In common with similar cases, the lawsuits were brought in the name of the entities behind each copyrighted work, such as Dallas Buyers Club, LLC and LHF Productions, Inc.

In time, however, things started to go wrong. Davis claims that he discovered that Crowell, in connection with and on behalf of the other named defendants, “misrepresented the true nature of the Copyright Litigation Campaign, including the ownership of the works at issue and the role of the various third-parties involved in the litigation.”

Davis says that Crowell and the other defendants (which include the infamous Germany-based troll outfit Guardaley) made false representations to secure his participation, while holding back other information that might have made him think twice about becoming involved.

“Crowell and other Defendants withheld numerous material facts that were known to Crowell and the knowledge of which would have cast doubt on the value and ethical propriety of the Copyright Litigation Campaign for Mr. Davis,” the lawsuit reads.

Davis goes on to allege serious misconduct, including that representations regarding ownership of various entities were false and used to deceive him into participating in the scheme.

As time went on, Davis said he had increasing doubts about the operation. Then, in August 2016 as a result of a case underway in California, he began asking questions which resulted in him uncovering additional facts. These undermined both the representations of the people he was working for and his own belief in the “value and ethical propriety of the Copyright Litigation Campaign,” the lawsuit claims.

Davis said this spurred him on to “aggressively seek further information” from Crowell and other people involved in the scheme, including details of its structure and underlying support. He says all he received were “limited responses, excuses, and delays.”

The case was later dismissed by mutual agreement of the parties involved but of course, Davis’ concerns about the underlying case didn’t come to the forefront until the filing of his suit against Crowell and the others.

Davis says that following a meeting in Santa Monica with several of the main players behind the litigation campaign, he decided its legal and factual basis were unsound. He later told Crowell and Guardaley that he was withdrawing from their project.

As the result of the misrepresentations made to him, Davis is now suing the defendants on a number of counts, detailed below.

“Defendants’ business practices are unfair, unlawful, and fraudulent. Davis has suffered monetary damage as a direct result of the unfair, unlawful, and fraudulent business practices set forth herein,” the lawsuit reads.

Requesting a trial by jury, Davis is seeking actual damages, statutory damages, punitive or treble damages “in the amount of no less than $300,000.”

While a payment of that not insignificant amount would clearly satisfy Davis, the prospect of a trial in which the Guardaley operation is laid bare would be preferable when the interests of its thousands of previous targets are considered.

Only time will tell how things will pan out but like the vast majority of troll cases, this one too seems destined to be settled in private, to ensure the settlement machine keeps going.

Note: The case was originally filed in June, only to be voluntarily dismissed. It has now been refiled in state court.

Hard Drive Stats for Q1 2017

Post Syndicated from Andy Klein original https://www.backblaze.com/blog/hard-drive-failure-rates-q1-2017/

2017 hard drive stats

In this update, we’ll review the Q1 2017 and lifetime hard drive failure rates for all our current drive models, and we’ll look at a relatively new class of drives for us – “enterprise”. We’ll share our observations and insights, and as always, you can download the hard drive statistics data we use to create these reports.

Our Hard Drive Data Set

Backblaze has now recorded and saved daily hard drive statistics from the drives in our data centers for over 4 years. This data includes the SMART attributes reported by each drive, along with related information such a the drive serial number and failure status. As of March 31, 2017 we had 84,469 operational hard drives. Of that there were 1,800 boot drives and 82,669 data drives. For our review, we remove drive models of which we have less than 45 drives, leaving us to analyze 82,516 hard drives for this report. There are currently 17 different hard drives models, ranging in size from 3 to 8 TB in size. All of these models are 3½” drives.

Hard Drive Reliability Statistics for Q1 2017

Since our last report in Q4 2016, we have added 10,577 additional hard drives to bring us to the 82,516 drives we’ll focus on. We’ll start by looking at the statistics for the period of January 1, 2017 through March 31, 2017 – Q1 2017. This is for the drives that were operational during that period, ranging in size from 3 to 8 TB as listed below.

hard drive failure rates by model

Observations and Notes on the Q1 Review

You’ll notice that some of the drive models have a failure rate of “0” (zero). Here a failure rate of zero means there were no drive failures for that model during Q1 2017. Later, we will cover how these same drive models faired over their lifetime. Why is the quarterly data important? We use it to look for anything unusual. For example, in Q1 the 4 TB Seagate drive model: ST4000DX000, has a high failure rate of 35.88%, while the lifetime annualized failure rate for this model is much lower, 7.50%. In this case, we only have a 170 drives of this particular drive model, so the failure rate is not statistically significant, but such information could be useful if we were using several thousand drives of this particular model.

There were a total 375 drive failures in Q1. A drive is considered failed if one or more of the following conditions are met:

  • The drive will not spin up or connect to the OS.
  • The drive will not sync, or stay synced, in a RAID Array (see note below).
  • The Smart Stats we use show values above our thresholds.
  • Note: Our stand-alone Storage Pods use RAID-6, our Backblaze Vaults use our own open-sourced implementation of Reed-Solomon erasure coding instead. Both techniques have a concept of a drive not syncing or staying synced with the other member drives in its group.

The annualized hard drive failure rate for Q1 in our current population of drives is 2.11%. That’s a bit higher than previous quarters, but might be a function of us adding 10,577 new drives to our count in Q1. We’ve found that there is a slightly higher rate of drive failures early on, before the drives “get comfortable” in their new surroundings. This is seen in the drive failure rate “bathtub curve” we covered in a previous post.

10,577 More Drives

The additional 10,577 drives are really a combination of 11,002 added drives, less 425 drives that were removed. The removed drives were in addition to the 375 drives marked as failed, as those were replaced 1 for 1. The 425 drives were primarily removed from service due to migrations to higher density drives.

The table below shows the breakdown of the drives added in Q1 2017 by drive size.

drive counts by size

Lifetime Hard Drive Failure Rates for Current Drives

The table below shows the failure rates for the hard drive models we had in service as of March 31, 2017. This is over the period beginning in April 2013 and ending March 31, 2017. If you are interested in the hard drive failure rates for all the hard drives we’ve used over the years, please refer to our 2016 hard drive review.

lifetime hard drive reliability rates

The annualized failure rate for the drive models listed above is 2.07%. This compares to 2.05% for the same collection of drive models as of the end of Q4 2016. The increase makes sense given the increase in Q1 2017 failure rate over previous quarters noted earlier. No new models were added during the current quarter and no old models exited the collection.

Backblaze is Using Enterprise Drives – Oh My!

Some of you may have noticed we now have a significant number of enterprise drives in our data center, namely 2,459 Seagate 8 TB drives, model: ST8000NM055. The HGST 8 TB drives were the first true enterprise drives we used as data drives in our data centers, but we only have 45 of them. So, why did we suddenly decide to purchase 2,400+ of the Seagate 8 TB enterprise drives? There was a very short period of time, as Seagate was introducing new and phasing out old drive models, that the cost per terabyte of the 8 TB enterprise drives fell within our budget. Previously we had purchased 60 of these drives to test in one Storage Pod and were satisfied they could work in our environment. When the opportunity arose to acquire the enterprise drives at a price we liked, we couldn’t resist.

Here’s a comparison of the 8 TB consumer drives versus the 8 TB enterprise drives to date:

enterprise vs. consumer hard drives

What have we learned so far…

  1. It is too early to compare failure rates – The oldest enterprise drives have only been in service for about 2 months, with most being placed into service just prior to the end of Q1. The Backblaze Vaults the enterprise drives reside in have yet to fill up with data. We’ll need at least 6 months before we could start comparing failure rates as the data is still too volatile. For example, if the current enterprise drives were to experience just 2 failures in Q2, their annualized failure rate would be about 0.57% lifetime.
  2. The enterprise drives load data faster – The Backblaze Vaults containing the enterprise drives, loaded data faster than the Backblaze Vaults containing consumer drives. The vaults with the enterprise drives loaded on average 140 TB per day, while the vaults with the consumer drives loaded on average 100 TB per day.
  3. The enterprise drives use more power – No surprise here as according to the Seagate specifications the enterprise drives use 9W average in idle and 10W average in operation. While the consumer drives use 7.2W average in idle and 9W average in operation. For a single drive this may seem insignificant, but when you put 60 drives in a 4U Storage Pod chassis and then 10 chassis in a rack, the difference adds up quickly.
  4. Enterprise drives have some nice features – The Seagate enterprise 8TB drives we used have PowerChoice™ technology that gives us the option to use less power. The data loading times noted above were recorded after we changed to a lower power mode. In short, the enterprise drive in a low power mode still stored 40% more data per day on average than the consumer drives.
  5. While it is great that the enterprise drives can load data faster, drive speed has never been a bottleneck in our system. A system that can load data faster will just “get in line” more often and fill up faster. There is always extra capacity when it comes to accepting data from customers.

    Wrapping Up

    We’ll continue to monitor the 8 TB enterprise drives and keep reporting our findings.

    If you’d like to hear more about our Hard Drive Stats, Backblaze will be presenting at the 33rd International Conference on Massive Storage Systems and Technology (MSST 2017) being held at Santa Clara University in Santa Clara California from May 15th – 19th. The conference will dedicate five days to computer-storage technology, including a day of tutorials, two days of invited papers, two days of peer-reviewed research papers, and a vendor exposition. Come join us.

    As a reminder, the hard drive data we use is available on our Hard Drive Test Data page. You can download and use this data for free for your own purpose, all we ask is three things 1) you cite Backblaze as the source if you use the data, 2) you accept that you are solely responsible for how you use the data, and 3) you do not sell this data to anyone, it is free.

    Good luck and let us know if you find anything interesting.

GumGum (Santa Monica, CA)
GumGum logo1GumGum is best known for inventing and popularizing the field of in-image advertising. Founded in 2008 by Ophir Tanz, the company is on a mission to unlock the value held within the vast content produced daily via social media, editorials, and broadcasts in a variety of industries. GumGum powers campaigns across more than 2,000 premium publishers, which are seen by over 400 million users.

In-image advertising was pioneered by GumGum and has given companies a platform to deliver highly visible ads to a place where the consumer’s attention is already focused. Using image recognition technology, GumGum delivers targeted placements as contextual overlays on related pictures, as banners that fit on all screen sizes, or as In-Feed placements that blend seamlessly into the surrounding content. Using Visual Intelligence, GumGum can scour social media and broadcast TV for all images and videos related to a brand, allowing companies to gain a stronger understanding of their audience and how they are relating to that brand on social media.

GumGum relies on AWS for its Image Processing and Ad Serving operations. Using AWS infrastructure, GumGum currently processes 13 million requests per minute across the globe and generates 30 TB of new data every day. The company uses a suite of services including but not limited to Amazon EC2, Amazon S3, Amazon Kinesis, Amazon EMR, AWS Data Pipeline, and Amazon SNS. AWS edge locations allow GumGum to serve its customers in the US, Europe, Australia, and Japan and the company has plans to expand its infrastructure to Australia and APAC regions in the future.

Jiobit (Chicago, IL)
Jiobit Team1
Jiobit was inspired by a real event that took place in a crowded Chicago park. A couple of summers ago, John Renaldi experienced every parent’s worst nightmare – he lost track of his then 6-year-old son in a public park for almost 30 minutes. John knew he wasn’t the only parent with this problem. After months of research, he determined that over 50% of parents have had a similar experience and an even greater percentage are actively looking for a way to prevent it.

Jiobit is the world’s smallest and longest lasting smart tag that helps parents keep track of their kids in every location – indoors and outdoors. The small device is kid-proof: lightweight, durable, and waterproof. It acts as a virtual “safety harness” as it uses a combination of Bluetooth, Wi-Fi, Multiple Cellular Networks, GPS, and sensors to provide accurate locations in real-time. Jiobit can automatically learn routes and locations, and will send parents an alert if their child does not arrive at their destination on time. The talented team of experienced engineers, designers, marketers, and parents has over 150 patents and has shipped dozens of hardware and software products worldwide.

The Jiobit team is utilizing a number of AWS services in the development of their product. Security is critical to the overall product experience, and they are over-engineering security on both the hardware and software side with the help of AWS. Jiobit is also working towards being the first child monitoring device that will have implemented an Alexa Skill via the Amazon Echo device (see here for a demo!). The devices use AWS IoT to send and receive data from the Jio Cloud over the MQTT protocol. Once data is received, they use AWS Lambda to parse the received data and take appropriate actions, including storing relevant data using Amazon DynamoDB, and sending location data to Amazon Machine Learning processing jobs.

Parsec (New York, NY)

Parsec operates under the notion that everyone should have access to the best computing in the world because access to technology creates endless opportunities. Founded in 2016 by Benjy Boxer and Chris Dickson, Parsec aims to eliminate the burden of hardware upgrades that users frequently experience by building the technology to make a computer in the cloud available anywhere, at any time. Today, they are using their technology to enable greater flexibility in the hardware and location that PC gamers choose to play their favorite games on. Check out this interview with Benjy and our Startups team for a look at how Parsec works.

Parsec built their first product to improve the gaming experience; gamers no longer have to purchase consoles or expensive PCs to access the entertainment they love. Their low latency video streaming and networking technologies allow gamers to remotely access their gaming rig and play on any Windows, Mac, Android, or Raspberry Pi device. With the global reach of AWS, Parsec is able to deliver cloud gaming to the median user in the US and Europe with less than 30 milliseconds of network latency.

Parsec users currently have two options available to start gaming with cloud resources. They can either set up their own machines with the Parsec AMI in their region or rely on Parsec to manage everything for a seamless experience. In either case, Parsec uses the g2.2xlarge EC2 instance type. Parsec is using Amazon Elastic Block Storage to store games, Amazon DynamoDB for scalability, and Amazon EC2 for its web servers and various APIs. They also deal with a high volume of logs and take advantage of the Amazon Elasticsearch Service to analyze the data.

Peloton (New York, NY)

The idea for Peloton was born in 2012 when John Foley, Founder and CEO, and his wife Jill started realizing the challenge of balancing work, raising young children, and keeping up with personal fitness. This is a common challenge people face – they want to work out, but there are a lot of obstacles that stand in their way. Peloton offers a solution that enables people to join indoor cycling and fitness classes anywhere, anytime.

Peloton has created a cutting-edge indoor bike that streams up to 14 hours of live classes daily and has over 4,000 on-demand classes. Users can access live classes from world-class instructors from the convenience of their home or gym. The bike tracks progress with in-depth ride metrics and allows people to compete in real-time with other users who have taken a specific ride. The live classes even feature top DJs that play current playlists to keep users motivated.

With an aggressive marketing campaign, which has included high-visibility TV advertising, Peloton made the decision to run its entire platform in the cloud. Most recently, they ran an ad during an NFL playoff game and their rate of requests per minute to their site increased from ~2k/min to ~32.2k/min within 60 seconds. As they continue to grow and diversify, they are utilizing services such as Amazon S3 for thousands of hours of archived on-demand video content, Amazon Redshift for data warehousing, and Application Load Balancer for intelligent request routing.

Tendril was founded in 2004 with the goal of helping homeowners better manage and reduce their energy consumption. Today, electric and gas utilities use Tendril’s data analytics platform on more than 140 million homes to deliver a personalized energy experience for consumers around the world. Using the latest technology in decision science and analytics, Tendril can gain access to real-time, ever evolving data about energy consumers and their homes so they can improve customer acquisition, increase engagement, and orchestrate home energy experiences. In turn, Tendril helps its customers unlock the true value of energy interactions.

AWS helps Tendril run its services globally, while scaling capacity up and down as needed, and in real-time. This has been especially important in support of Tendril’s newest solution, Orchestrated Energy, a continuous demand management platform that calculates a home’s thermal mass, predicts consumer behavior, and integrates with smart thermostats and other connected home devices. This solution allows millions of consumers to create a personalized energy plan for their home based on their individual needs.

Tendril builds and maintains most of its infrastructure services with open sources tools running on Amazon EC2 instances, while also making use of AWS services such as Elastic Load Balancing, Amazon API Gateway, Amazon CloudFront, Amazon Route 53, Amazon Simple Queue Service, and Amazon RDS for PostgreSQL.
