Wayland Is Still In Ubuntu 14.10

Ubuntu

Still packages and found within the Ubuntu Utopic (14.10) archive are the various Wayland packages. Right now within Ubuntu Universe is Wayland 1.5, the Weston 1.5 compositor release, and various other Wayland-related packages like for VA-API acceleration, the basic GLMark2 benchmark for Wayland, etc. Granted, most of these packages were just supplied by the upstream Debian base and are of no special interest to Canonical. The Wayland packages for Utopic can be found by this package search.

BattBorg: power your Raspberry Pi with almost any kind of battery

Filed under
Development
Linux

The BattBorg supports most off-the-shelf batteries or battery packs between 7-36V and offers up to 14 hours of battery life for the Model B+ from 8xAA rechargeables…
“The BattBorg is a power converter for your Raspberry Pi which allows you to power the Raspberry Pi off batteries,” explains PiBorg’s Tim Freeburn. “It will work with most batteries/battery packs that are between 7-36V so it’s great for 12V car batteries, 8xAA battery packs, and so on. We’re including an AA battery holder in two of the kits as rechargeable AA’s are inexpensive, and readily available at most shops, and Ebay.”

Compiler wars: LLVM and GCC compete on speed, security

Filed under
Development
GNU

LLVM has also recently inspired a project named Vellvm, where the design of the program and its output are both formally verified. The compiler's input and production can then be independently proven as consistent to defend against introduced bugs. The CompCert compiler already does this, but only for C; a formally verified version of LLVM could in theory do this for any language.

Interviews

After watching classic TV shows such as Knight Rider and Street Hawk in his youth, IT professional and Raspberry Pi enthusiast Derek Knaggs was inspired to create a low-cost in-car computer using a Raspberry Pi.
The Pi sits in the centre console of his Ford Focus, wired to the display of an Xtrons DVD player (optional) as well as two TFT screens in the rear headrests. Control is via a Xenta wireless keyboard with mouse touchpad, while a smartphone can be used as a wireless hotspot to give the Pi an internet connection on the move.
Having recently added a reverse camera to his already top-notch project, we caught up with Derek to learn more about it…

LLVM 3.5 Is Finally Available For Download

Filed under
Development
BSD

LLVM 3.5 is now available for fans just not looking for a more liberally licensed compiler but for those dependent upon AMD's GPU LLVM compiler back-end and the other innovative use-cases provided by the LLVM stack.

While no official announcement has yet to hit the mailing lists, LLVM 3.5 and its sub-projects doing 3.5 releases are now available via the download page. LLVM 3.5 brings many new features ranging from better support of new C++ standards to improved back-end compiler targets. Benchmarks on conventional x86_64 Linux targets have shown LLVM/Clang 3.5 performing well but the in-development GCC 5.0 still performing better.

GCC 5.0 Outruns LLVM 3.5 Compiler By A Bit On Core-AVX2

Filed under
Development
GNU
Graphics/Benchmarks

In anticipation of the LLVM 3.5 release that brings a number of new compiler features -- including possible performance improvements from our benchmarking done earlier today -- here's some benchmarks comparing LLVM Clang 3.5 RC3 to a recent SVN snapshot of the GCC 5.0 compiler that's presently under development.

GCC 5.0 is still under heavy stage one development and isn't anticipated for release likely until H1'2015, so there's still a ways to go with the GNU Compiler Collection, but these brief benchmarks today should provide some nice perspective for how it's shaping up against LLVM Clang 3.5. Of course, as GCC 5.0 nears, we'll have plenty more compiler benchmarks over the months ahead.

INTERMEDIATE RESULTS OF THE ICON TESTS: BREEZE

Filed under
Development
KDE

The introduction of the new Breeze icon set in KDE let us again wonder, what aspects of an icon set actually takes what impact on the usability of it. We investigated Oxygen and Tango Icons for the LibreOffice project before, but our focus then was on checking all icons of the standard tool bar. This time we focus on different icon sets and will use 13 common actions to compare them.
With this series we are going to test at least 10 different free icon sets: Breeze, Oxygen, Tango, Faenza, Nuvola, Nitrux, Elementary, Crystal Project, Humanity and Treepata. These icon sets differ on various aspects: use of color and details, flat or not and sometimes even on the metaphor used.

LLVM Clang 3.5 Brings Some Compiler Performance Improvements

Filed under
Development
BSD

If all goes well, LLVM 3.5 will be released today. While we have already delivered some LLVM/Clang benchmarks of the 3.5 SVN code, over the days ahead we will be delivering more benchmarks of the updated compiler stack -- including looking at its performance against the in-development GCC 5.0. For getting this latest series of compiler benchmarking at Phoronix started, here's some fresh numbers of LLVM Clang 3.4 compared to a recent release candidate of LLVM Clang 3.5.

This article is using a CompuLab Intense-PC with Intel Core i7 3517UE Ivy Bridge processor for LLVM Clang 3.4 vs. LLVM Clang 3.5 benchmarking. The host system was Ubuntu 14.04 x86_64 and was running off the Linux 3.17 development kernel. Both compilers were built in their optimized release mode (--disable-assertions --enable-optimized) for the core-avx-i CPU. Aside from switching out LLVM Clang 3.4 for LLVM Clang 3.5 RC4, no other system changes were made.

How to set up Raspberry Pi, the little computer you can cook into DIY tech projects

Filed under
Development
Linux

You don't need an electrical engineering degree to build a robot army. With the $35 Raspberry Pi B+, you can create robots and connected devices on the cheap, with little more than an Internet connection and a bunch of spare time.

The Raspberry Pi is a computer about the size of a credit card. The darling of the do-it-yourself electronics crowd, the Pi was originally designed to teach kids computer and programming skills without the need for expensive computer labs. People have used Raspberry Pis for everything from robots to cheap home media centers.

The Pi sports USB ports, HDMI video, and a host of other peripherals. The latest version, the B+, sports 512MB of RAM and uses a MicroSD card instead of a full-size card.

Open source history, present day, and licensing

Looking at open source softwares particularly, this is a fact that is probably useful to you if you are thinking about business models, many people don't care about it anymore. We talk about FOSS, Free and Open Source Software, but if we really are strict there's a difference between free software and open source software. On the left, I have free software which most typically is GPL software. Software where the license insures freedom. It gives freedoms to you as a user, but it also requires that the freedoms are maintained. On the right-hand side, you have open source software which is open for all, but it also allows you to close it. So here we come back to the famous clause of the GPL license, the reciprocity requirement which says, "If I am open, you need to be open." So software that comes under the GPL license carries with it something that other people call a virus. I call it a blessing because I think it's great if all software becomes open. Read more

Mozilla Wants to Save the Open Web, but is it Too Late?

Again, I think this is absolutely correct. But what it fails to recognise is that one of the key ways of making the Web medium "less free and open" is the use of legally-protected DRM. DRM is the very antithesis of openness and of sharing. And yet, sadly, as I reported back in May, Mozilla has decided to back adding DRM to the Web, starting first with video (but it won't end there...) This means Mozilla's Firefox is itself is a vector of attack against openness and sharing, and undermines its own lofty goals in the Open Web Fellows programme. Read more

Chakra-2014.09-Euler released

The Chakra team is happy to announce the first release of the Chakra Euler series, which will follow the 4.14 KDE releases. A noticeable change in this release is the major face-lift of Kapudan, which now gives the option to users to enable the [extra] repository during first boot so they can easily install the most popular GTK-based applications. Kudos to george2 for the development and Malcer for the artwork. Read more
