Supercomputing on the cheap with Parallella

Blowing open the doors to low-power, on-demand supercomputing

Parallella topview

Packing impressive supercomputing power inside a small credit card-sized board running Ubuntu, Adapteva‘s $99 ARM-based Parallella system includes the unique Ephiphany numerical accelerator that promises to unleash industrial strength parallel processing on the desktop at a rock-bottom price. The Massachusetts-based startup recently ran a successfully funded Kickstarter campaign and gained widespread attention only to run into a few roadblocks along the way. Now, with their setbacks behind them, Adapteva is slated to deliver its first units mid-December 2013, with volume shipping in the following months.

What makes the Parallella board so exciting is that it breaks new ground: imagine an Open Source Hardware board, powered by just a few Watts of juice, delivering 90 GFLOPS of number crunching. Combine this with the possibility of clustering multiple boards, and suddenly the picture of an exceedingly affordable desktop supercomputer emerges.

This review looks in-depth at a pre-release prototype board (so-called Generation Zero, a development run of 50 units), giving you a pretty complete overview of what the finished board will look like.

Upward Mobility: The Forgotten Mobile Platforms

They may not be as pretty, but low cost embedded computing is a big thing

When thinking about the mobile development space, it’s easy to make the mistake of restricting it to smartphones. Apple, Google, Microsoft, and the stragglers dominate the news, and seeing someone typing away at a handset has become ubiquitous. But below the surface, there’s another set of mobile platforms that tend to get ignored, outside the DIY community, but are revolutionizing the world in their own way.

Traditionally, embedded computing was restricted to high-volume commercial applications (e.g., smart refrigerators and automobile control systems.) The intrepid hackers dabbled, but the amount of hardware knowledge required to get a CPU, memory and I/O logic onto a breadboard prevented any but the most experienced from implementing their own low-power embedded creations.

The Myth of the Private API

The Fundamental Interconnectedness of Things

A little over a week ago, I wrote about how the authentication model for an unpublished Tesla REST API was architecturally flawed because it failed to take basic precautions against the sharing of credentials with third-parties common to most REST-based services these days. Since its publication, the main criticism of the article centered around the fact that the API is neither a published API nor has it been advertised as being meant for third-party consumption.

The adding of value to devices and services with or without the knowledge/permission of their creators is an integral part of the Internet of Things. These days, people expect an API around their devices. They will discover any APIs and add value to the device/service—even if the task requires a little reverse engineering work. A responsible creator of a device or service in today’s world defined by the Internet of Things must therefore do the following things—always:

  1. Give it a public API
  2. Protect any internal communications so they can’t be reverse engineered
  3. Protect any public communications so that they don’t put end users at risk when they leverage third-party devices and services

So, You Want to Run a Young Coders Class?

Teaching Future Coders

Ever since PyCon 2013, the interest in the Young Coders class has been intensifying. Practically every Python conference since then has asked about doing one, and several have run their own. Classes outside of conferences have sprung up, as well, from one time workshops to after school clubs.

As more classes happen, more people have been asking about running their own. These classes do take quite a bit of effort to set up, but the payoff is enormous. Also, once you do one, doing subsequent ones gets easier and easier.

Rapping about RepRap

OSCON 2013 Speaker Series

Ed Snajder is a 3D-printer aficionado, DBA at Jive Software and OSCON 2013 speaker. We talk about the ins and outs of the new world of 3D printing (a little sneak preview of what Ed will be speaking about at this year’s OSCON). If you are interested in attending to check out Ed’s talk or the many other cool sessions, click over to the OSCON website where you can use the discount code OS13PROG to get 20% your registration fee.

Key highlights include:

  • What is RepRap? [Discussed at 0:20]
  • Hack a printer together from scratch, purchase a kit or get one ready to print (sort of) [Discussed at 3:15]
  • How do you get from 2D to 3D? [Discussed at 5:54]
  • If you smell popcorn and you’re not making it, your 3D printer is burning [Discussed at 9:59]
  • Creating a greener world one object at a time [Discussed at 12:36]
  • 3D printer = Piracy machine? [Discussed at 14:25]

A First Slice of Raspberry Pi

Tips on Getting Started with Simon Monk

Simon Monk @simonmonk2 is a full-time author who focuses his writing talents on open source hardware topics. He is currently writing the Raspberry Pi Cookbook which will be available in early release in July and in final release in the fall. Recently, I had the opportunity to sit down with Simon and we talked about one of the coolest things in open source hardware today, the Raspberry Pi.

Key highlights include:

  • Invest in a Raspberry Pi starter kit [Discussed at 0:29]
  • Python is probably the best bet for beginners [Discussed at 1:25]
  • Raspberry Pi and Arduino are both great but really excel in different ways [Discussed at 3:54]
  • How about when Raspberry Pi and Arduino are used together? [Discussed at 5:14]
  • Save time and avoid common mistakes like hardware compatibility issues [Discussed at 7:23]
  • Overclocking helps performance [Discussed at 8:47]

Developer Week in Review: The new iPad and the big meh

Developer Week in Review: The new iPad and the big meh

It's iPad evolution rather than revolution, increasing patent penalties for Android, and Raspberry Pi is served.

Apple unveils pretty much what it was expected to unveil, and decides to treat Android as a cash cow rather than an enemy. Meanwhile, the Raspberry Pi is finally out, so let the hacking begin.

Developer Week in Review: Adobe sends Flex to Apache

Developer Week in Review: Adobe sends Flex to Apache

Flex goes FLOSS, some cheap Pi, and brain on a chip.

Adobe just gave away Flex, a new single-board computer might dethrone Arduino as the tool of choice for makers, and researchers bring us a step closer to our robotic overlords.
