WebExtensions in Firefox 48

Friday 29th of April 2016 10:45:38 PM

At the Mozilla blog, Andy McKay announces that the browser maker has officially declared WebExtensions ready to use for add-on development. "With the release of Firefox 48, we feel WebExtensions are in a stable state. We recommend developers start to use the WebExtensions API for their add-on development." The WebExtensions support released for Firefox 48 includes improvements to the "alarms, bookmarks, downloads, notifications, webNavigation, webRequest, windows and tabs" APIs, support for a new Content Security Policy that limits where resources can be loaded from, and support in Firefox for Android. LWN looked at the WebExtensions API in December.

X.Org votes to join SPI

Thursday 28th of April 2016 03:08:22 PM

The results of the X.Org election are in. There were two things up for a vote: four seats on the board of directors and amending the bylaws to join Software in the Public Interest (SPI). Unlike last year's election, this year's vote met the required 2/3 approval to join SPI (61 voters out of 65 members, with 54 voting "Yes", 4 "No", and 3 "Abstain"). In addition, Egbert Eich, Alex Deucher, Keith Packard, and Bryce Harrington were elected to the board.

New functional programming language can generate C, Python code for apps (InfoWorld)

Tuesday 26th of April 2016 08:24:42 PM
InfoWorld introduces Futhark, an open source functional programming language designed for creating code that runs on GPUs. It can automatically generate both C and Python code to be integrated with existing apps. "Most GPU programming involves using frameworks like OpenCL or CUDA, both of which use variations of C or C++ to generate code that runs on the GPU. Futhark can generate C code, but is its own language, more similar to Haskell or Standard ML than C. (Futhark is itself written in Haskell.) Futhark's creators claim that the expressiveness of the language makes it easier to describe complex operations that use parallelism. This includes the ability to support nested parallelizations (parallel operations inside other parallel operations). Futhark can do this "despite the complexities of efficiently mapping to the flat parallelism supported by hardware, as a great many programs depend on this feature," say the language's creators."

Finding a new home for Thunderbird

Tuesday 26th of April 2016 08:52:58 AM
The Mozilla Foundation has (in the guise of Gervase Markham) posted an update on the process of spinning off the Thunderbird mail client as a separate project. As part of that, they engaged Simon Phipps to write up a survey of possible new homes [PDF] for the project. "Having reviewed the destinations listed below together with several others which were less promising, I believe there are three viable choices for a future home for the Thunderbird Project; Software Freedom Conservancy, The Document Foundation and a new deal at the Mozilla Foundation. None of these three is inherently the best, and it is possible that over time the project might seek to migrate to a 'Thunderbird Foundation' as a permanent home (although I would not recommend that as the next step)."

Intel releases the Arduino 101 firmware source code

Monday 25th of April 2016 10:04:47 PM
Arduino has announced the release of the source code for the real-time operating system (RTOS) powering the Arduino 101 and Genuino 101. "The package contains the complete BSP (Board Support Package) for the Curie processor on the 101. It allows you to compile and modify the core OS and the firmware to manage updates and the bootloader. (Be careful with this one since flashing the wrong bootloader could brick your board and require a JTAG programmer to unbrick it)." (Thanks to Paul Wise)

Kernel prepatch 4.6-rc5

Monday 25th of April 2016 08:36:48 AM
Linus has released the 4.6-rc5 kernel prepatch. "Things continue to be fairly calm: rc5 is bigger than rc4 was, but rc4 really was tiny. And while we're back to fairly normal commit counts for this time in the release window, the kinds of bugs people are finding remain very low grade: there's absolutely nothing scary in here. If things continue this way, this might be one of those rare releases that don't even get to rc7."

Rintel: Network Manager 1.2 is here

Friday 22nd of April 2016 11:42:58 PM

At his blog, Lubomir Rintel highlights some of the changes found in the new 1.2 release of Network Manager, the network-configuration utility suite shipped by many Linux distributions. High on the list are privacy improvements; the post notes that "the identity of a mobile host can also leak via Wi-Fi hardware addresses. A common way to solve this is to use random addresses when scanning for available access points, which is what NetworkManager now does (with a recent enough version of wpa_supplicant). The actual hardware address is used only after the device is associated to an access point." Network Manager can also now be used to manage tun, tap, macvlan, vxlan and IP tunnel software devices, and can run multiple VPN modules simultaneously. In addition, support for several hardware device classes was split into loadable modules, which will reduce memory overhead.
