Raspberry Pi 2 vs Creator 120

Filed under

Hardware
Reviews

The Creator 120 and the Raspberry Pi 2 are single-board computers designed for developers and hobbyists.

The Creator C120 was announced in late 2014, but started shipping at about the same time that the Raspberry Pi 2 was announced/starting shipping, which was just last week.

I haven’t purchased a Raspberry Pi 2 yet, but I received a Creator 2 from the manufacturer this week. It was a prize I won in December and the first prize I ever won on the Internet. I’ve been playing with it all day and find it to be a very capable single-board computer. Out of the box, it’s mostly a plug-and-play device.

Review: 2015 Dell XPS 13 (9343) Running Linux

Filed under
Hardware
Reviews

When and if Eric reads this he’s just going to shake his head. For two years in a row now I’ve been lured by the wonders of new laptops announced at CES, and in both years I’ve been disappointed. He tells me I’m stupid for ordering the “new shiny” and expecting it to work, but I refuse to give up my dream.

Luckily this isn’t a huge issue for me since my main machines are desktops, but my second generation Dell XPS 13 “sputnik” is getting a little old. I am really looking forward to a slightly larger screen. The pixel density isn’t great on my laptop, especially compared to what is out now, and I am finding myself a little cramped for screen real estate.

Attention Linux gamers: Valve, Khronos to reveal next-gen OpenGL successor at GDC

Gaming

It's a great time to be alive if you're a fanatic about the particulars of various performance-boosting graphics APIs. AMD's Mantle is here, Microsoft's DirectX 12 is coming with Windows 10, and at GDC in early March we'll hear the first news about a successor to the open-source, cross-platform OpenGL API.

That's not necessarily huge news if you're using a Windows machine—unless this OpenGL successor is really special, most games will probably stick with DirectX 12 in a perpetual love/hate relationship. If you're a Mac or Linux gamer, however, the next-generation OpenGL is potentially a huge deal.

Hardware
Reviews

There's plenty of excitement in the Raspberry Pi world this week: the big news is the announcement of the Raspberry Pi 2 hardware - the long-awaited and much-anticipated successor to the immensely popular original unit, which will now be known as the Raspberry Pi 1.

But that's not the only news: there is also a new release of the Raspbian operating system and the NOOBS (New Out Of Box Software) package. I am just back from a week in Amsterdam, and will be leaving in a few days for a short trip to Iceland, so I just have time to download and install the new software on my two Raspberry Pi 1 units (Model B and B+), and I have ordered a RPi 2 so I hope that will be waiting for me when I return. At least, the Swiss Pi-Shop says that it will be available on 3 February so I am keeping my fingers crossed - because almost all of the excitement is about the Raspberry Pi 2.

A bundled microSD card arrives preinserted into the rear of the CuBox-i, and it’s loaded with a version of Google’s Android operating system. Interestingly, SolidRun has gone to the effort of seeking the certifications required to load the Google Apps suite onto the card, meaning users receive Google Mail, YouTube, Google Maps and full access to Google Play straight out of the box. An even newer build, based on the latest Android 4.4 KitKat branch, can be downloaded from SolidRun’s website and provides an entirely useable desktop Android experience.

Back in September AMD announced new FX CPUs that included the FX-8370, FX-8370E, and FX-8320E. Back then we reviewed the FX-8370/FX-8370E CPUs under Linux but at the time didn't have our hands on the more affordable FX-8320E processor. In December AMD sent over the FX-8320E and so for the past few weeks I've been happily using this new Vishera CPU.

HowTos

If you’re not up for spending your money on one of the less advanced smart watch models, you may want to check out maker Jonathan Cook’s DIY Open-Source SmartWatch, part of which is 3D printed, something the prognosticators of future tech surely didn’t forecast. Cook shared instructions for making his SmartWatch on the webzine “Make:” and also on his own website, DoNothingBox. You can download the STL files on the DNB site, too. For around $125 or less you can make your own smart phone and you can customize it, something that you wouldn’t be able to do with a store-bought version.

Open Source Haptics Kit Aims to Democratize Force Feedback

Filed under
Hardware
OSS

quick terminology dive: a spacial haptic device is a physical manipulator that enables exploration of a virtual space through force feedback. A user grips the “manipulandum” (the handle) and moves it within the work area defined by the physical design of the device. Spacial Haptic Devices have been around for years and serve as excellent tools for telling their users (surgeons) what something (tumor) “feels like.”

In our case, this haptic device is a two-link, two-joint system grounded on a base station and providing force feedback with servo motors and tensioned wire ropes. The manipulator itself supports 3-degree-of-freedom movement of the end-effector (translations, but no rotations) which is tracked with encoders placed on all joints. To enable feedback, joints are engaged with cable-drive transmissions.

BeagleBone SBC beefs up Lego Mindstorms EV3

An “EVB” Kickstarter project replaces the Lego Mindstorms EV3 robot’s ARM9 brick with a BeagleBone Black, adding performance, expandability, and sensors.

When Lego added a Linux-based “Brick” computer to its modular, open source Lego Mindstorms robot platform, we were psyched, but were also somewhat disappointed it was only a modest ARM9-based device. Now, a startup called Fatcatlab has found Kickstarter success with an EVB computer you can use in place of the Brick that is designed to plug in a BeagleBone Black for a much faster 1GHz Cortex-A8 experience.

5 favorite Raspberry Pi and Arduino projects

Filed under
Linux
Hardware
OSS

It has never been a better time to understand the components that fit together to make the hardware we use work. To do that, lets look at my five favorite open hardware projects.

First, what do I mean by open hardware? I mean that the components that make up a device are available for the user to see. No secret formulas. The ingredients are completely transparent, and if you chose, you can source the raw parts and assemble them yourself. You can also learn from the process of assembly and with a team spirit share any problems encountered, then improving the formula of the device. For example, you could suggest better parts or improve the code to make it run faster.

  • Apache Graduates Another Big Data Project to Top Level
    For the past year, we've taken note of the many projects that the Apache Software Foundation has been elevating to Top-Level Status. The organization incubates more than 350 open source projects and initiatives, and has squarely turned its focus to Big Data and developer-focused tools in recent months. As Apache moves Big Data projects to Top-Level Status, they gain valuable community support. Only days ago, the foundation announced that Apache Kudu has graduated from the Apache Incubator to become a Top-Level Project (TLP). Kudu is an open source columnar storage engine built for the Apache Hadoop ecosystem designed to enable flexible, high-performance analytic pipelines. And now, Apache Twill has graduated as well. Twill is an abstraction over Apache Hadoop YARN that reduces the complexity of developing distributed Hadoop applications, allowing developers to focus more on their application logic.
  • Spark 2.0 takes an all-in-one approach to big data
    Apache Spark, the in-memory processing system that's fast become a centerpiece of modern big data frameworks, has officially released its long-awaited version 2.0. Aside from some major usability and performance improvements, Spark 2.0's mission is to become a total solution for streaming and real-time data. This comes as a number of other projects -- including others from the Apache Foundation -- provide their own ways to boost real-time and in-memory processing.
  • Why Uber Engineering Switched from Postgres to MySQL
    The early architecture of Uber consisted of a monolithic backend application written in Python that used Postgres for data persistence. Since that time, the architecture of Uber has changed significantly, to a model of microservices and new data platforms. Specifically, in many of the cases where we previously used Postgres, we now use Schemaless, a novel database sharding layer built on top of MySQL. In this article, we’ll explore some of the drawbacks we found with Postgres and explain the decision to build Schemaless and other backend services on top of MySQL.
  • GNU Hyperbole 6.0.1 for Emacs 24.4 to 25 is released
    GNU Hyperbole (pronounced Ga-new Hi-per-bo-lee), or just Hyperbole, is an amazing programmable hypertextual information management system implemented as a GNU Emacs package. This is the first public release in 2016. Hyperbole has been greatly expanded and modernized for use with the latest Emacs 25 releases; it supports GNU Emacs 24.4 or above. It contains an extensive set of improvements that can greatly boost your day-to-day productivity with Emacs and your ability to manage information stored across many different machines on the internet. People who get used to Hyperbole find it helps them so much that they prefer never to use Emacs without it.
  • Belgium mulls reuse of banking mobile eID app

  • Water resilience that flows: Open source technologies keep an eye on the water flow
    Communities around the world are familiar with the devastation brought on by floods and droughts. Scientists are concerned that, in light of global climate change, these events will only become more frequent and intense. Water variability, at its worst, can threaten the lives and well-beings of countless people. Sadly, humans cannot control the weather to protect themselves. But according to Silja Hund, a researcher at the University of British Columbia, communities can build resilience to water resource stress. Hund studies the occurrence and behavior of water. In particular, she studies rivers and streams. These have features (like water volume) that can change quickly. According to Hund, it is essential for communities to understand local water systems. Knowledge of water resources is helpful in developing effective water strategies. And one of the best ways to understand dynamic water bodies like rivers is to collect lots of data.
