Linux module controls micro-helicopters

Filed under

Hardware

Gumstix announced an “AeroCore” MAV (micro air vehicle) controller board that runs NuttX on a Cortex-M4 MCU, plus Linux on a Cortex-A9-based DuoVero COM.

The AeroCore MAV control board is principally run by a separately available Yocto Linux-based DuoVero Zephyr or DuoVero Crystal computer-on-module (COM) that plugs into the board. The AeroCore itself includes an ARM Cortex-M4 microcontroller unit (MCU), which is said to be directly interfaced with the DuoVero. The device is intended for developers of micro air vehicles such as tiny helicopters or quadrocopter drones.

Our source added that the completion of Valve’s Steam Controller was the final piece that would precede the availability of most Steam Machines, which indicates that Steam Machines will also begin to release at the end of the year. The source also told PC Gamer that they expect “about 500” games to be natively playable on SteamOS by the end of this year, up from the current count of 382.

The Results Of Optimizing Radeon's VRAM Behavior

Filed under
Graphics/Benchmarks
Hardware

For those wishing to test out the new Radeon code, Lauri's repositories for this work are this kernel repository and this Mesa repository. He said in an email this morning to me, "The code won't be changing beyond cleanups, there might be small edits to the thesis draft. As the main target was VRAM pressure, it will be pointless to test ioq3 games on 2 GB VRAM, for example - they will show no difference, as they fit completely into VRAM. You can use the radeon.vramlimit=256 kernel parameter to limit VRAM for testing different amounts. The kernel is fully backwards compatible with old mesa, so you should be able to compare just by changing mesa and the vram limit. I should note that there's a big ioq3 regression currently in mesa git[3], so if your comparison mesa is too far back, it could seem like it was caused by my work, when it's in reality in master too."

This latest driver update arrives only a day after the previous Beta release, which caused quite a stir because it featured the option to overclock the video card. It may not seem like much but, in fact, this is actually great progress for the NVIDIA drivers.

Linux
Hardware

As we've reported many times, the diminutive $25/$35 Linux computer dubbed Raspberry Pi has emerged as one of the biggest open source stories anywhere over the past couple of years. It's attracted all kinds of developers and tinkerers, is now running many different flavors of Linux, and there is even now a supercomputer consisting of many Pi devices lashed together with Lego pieces. In some of the more exotic new applications for Raspberry Pi, it's being used in music, robotics and security scenarios.

Citrix and Google partner to bring native enterprise features to Chromebooks

Chromebooks are making inroads into the education sector, and a push is coming for the enterprise with new native Chrome capabilities from Citrix. Google and Citrix have announced Citrix Receiver for Chrome, a native app for the Chromebook which has direct access to the system resources, including printing, audio, and video. To provide the security needed for the enterprise, the new Citrix app assigns a unique Receiver ID to each device for monitoring, seamless Clipboard integration across remote and local applications, end user experience monitoring with HDX Insight, and direct SSL connections.

Is Open Source an Open Invitation to Hack Webmail Encryption?

While the open source approach to software development has proven its value over and over again, the idea of opening up the code for security features to anyone with eyeballs still creates anxiety in some circles. Such worries are ill-founded, though. One concern about opening up security code to anyone is that anyone will include the NSA, which has a habit of discovering vulnerabilities and sitting on them so it can exploit them at a later time. Such discoveries shouldn't be a cause of concern, argued Phil Zimmermann, creator of PGP, the encryption scheme Yahoo and Google will be using for their webmail. Read more

Changing times, busy times and why Google will save Usenet.

Linux however has succeeded by way of form factors diversifying. Be it Android phones or tablets there is a big shift with the mainstream consumer in terms of what devices they want and here Linux has excelled. In 2008 my decision remove my Microsoft dependency was for reasons of the control they had on the desktop, the practices alleged against them and the dubious tactics some of their advocates used to promote the products. I also wholeheartedly agree with the ethos of FOSS which was another contributory factor. Today, my feelings about FOSS have not changed, there are caveats to my opinions of FOSS (especially in gaming) but I’ve covered that before in other articles. Today I avoid Microsoft not because I feel the need to make a stand against its behaviour, its because I don’t need them. I support Microsoft being a “choice” in the market as I support user freedom, but as for what Microsoft can offer me (regardless of its past) there is nothing. Read more

Eltechs Debuts x86 Crossover Platform for ARM Tablets, Mini-PCs

The product, called ExaGear Desktop, runs x86 operating systems on top of hardware devices using ARMv7 CPUs. That's significant because x86 software, which is the kind that runs natively on most computing platforms today, does not generally work on ARM hardware unless software developers undertake the considerable effort of porting it. Since few are likely to do that, having a way to run x86 applications on ARM devices is likely to become increasingly important as more ARM-based tablets and portable computers come to market. That said, the ExaGear Desktop, which Eltechs plans to make available next month, currently has some steep limitations. First, it only supports Ubuntu Linux. And while Eltechs said support for additional Linux distributions is forthcoming, there's no indication the product will be able to run x86 builds of Windows on ARM hardware, a feat that is likely to be in much greater demand than Linux compatibility.
