I ricercatori del Computer Science and Artificial Intelligence Laboratory (CSAIL), del MIT (Massachusetts Institute of Technology), hanno annunciato di aver sviluppato un nuovo linguaggio di programmazione chiamato "Halide". Halide è stato progettato per semplificare lo sviluppo di applicazioni riguardanti l'Image Processing.
Adding a new function to an image-processing program, or modifying it to run on a different device, often requires rethinking and revising it from top to bottom.
Researchers at MIT's Computer Science and Artificial Intelligence Laboratory (CSAIL) aim to change that, with a new programming language called Halide. Not only are Halide programs easier to read, write and revise than image-processing programs written in a conventional language, but because Halide automates code-optimization procedures that would ordinarily take hours to perform by hand, they’re also significantly faster.
Rilasciato sotto licenza MIT, Halide è disponibile per piattaforme x86-64/SSE, ARM v7/NEON e CUDA. Il compilatore è attualmente disponibile per le recenti release di Mac OS X e Linux. Il supporto per sistemi Windows è tecnicamente fattibile, ma per ora non è stato testato su sistemi Windows.
Google rilascia un nuovo update per il suo browser Chrome
The Stable channel has been updated to 21.0.1180.75 for Mac OS X, Linux, Windows and Chrome Frame
This build fixes:
- Flash videos not longer remaining in fullscreen when clicking a secondary monitor while the video is playing (Issue: 140366).
- Flash video full screen displays on wrong monitor (Issue: 137523)
- REGRESSION: Rendering difference in Chrome 21 and 22 that affected on Persian Wikipedia (Issue: 139502)
- Some known crashes (Issues: 137498, 138552, 128652, 140140)
- Audio objects are not "switched" immediately (Issue: 140247)
- Print and Print Preview ignore paper size default in printer config (Issue: 135374)
- Candidate windows is shown in wrong place in Retina display (Issue: 139108)
- more of the choppy and distorted audio issues (Issue: 136624)
- Japanese characters showing in Chinese font (Issue: 140432)
- Video playback issues with flash-based sites (Issue: 139953)
- Sync invalidation notification broken after restart (Issue: 139424)
Rilasciata la versione 3.6.0 di LibreOffice
This is the first release from the 3.6 branch of LibreOffice.
It contains many exciting new features, and is the recommended version for early adopters.
The following notes apply:
- This release is bit-for-bit identical to the 3.6.0 Release Candidate 4, so you don't need to download or reinstall if you have that version already.
- If you update from an earlier version, spellchecking might be broken. In this case, the following workaround helps:
- On Linux, in a terminal window enter "rm -r ~/.config/libreoffice/3/user/extensions"
- On Mac OS X, in a Terminal window enter "rm -r ~/Library/Application Support/LibreOffice/3/user/extensions"
- On Windows, in a Command Prompt window enter "rmdir /q /s %appdata%LibreOffice3userextensions"
- After that, please restart LibreOffice twice.
- The distribution for Windows is an international build, so you can choose the user interface language that you prefer. Help content is available via an online service, or alternatively as a separate install.

Annunciato il rilascio della nuova versione di Zorin OS, distribuzione Linux basata da Ubuntu.
The Zorin OS Team are proud to release the Zorin OS 6 Core and Ultimate, the latest version of our operating system designed for Windows users and those who are dissatisfied with the Unity and Gnome Shell offerings. At the core of Zorin OS 6 lies our new, unique desktop environment named "Zorin Desktop". We also include our innovative Zorin Look Changer which allows users to choose between the Windows 7, Windows XP and GNOME 2 graphical interfaces (in Core) as well as the Mac OS X, Unity and Windows 2000 interfaces in Zorin OS Ultimate. Zorin Desktop embraces all of the latest and greatest Open Source software and technologies such as Gtk3 and other software from the GNOME 3 software stack, all without affecting the familiarity, usability and customizability of the desktop and retaining the Compiz window manager. Along with the new desktop environment, Zorin OS 6 packs a ton of software updates: a newly redesigned Software Center, Linux Kernel version 3.2 and a load of other improvements and features. We also include our Zorin Web Browser Manager, Zorin Background Plus (Ultimate only) and other programs from our earlier versions. As Zorin OS 6 is based on Ubuntu 12.04 it is an LTS (Long Term Support) release, provided with 5 years of security updates.

Rilasciata la prima alpha di Ubuntu 12.10, codename 'Quantal Quetzal'. Note di rilascio disponibili a questa pagina
Linux kernel3.4Quantal Alpha-1 includes the 3.4.0-5.11 Ubuntu kernel which was based on the final v3.4 upstream Linux kernel. This is an update from the 3.2.0-23.36 Ubuntu kernel which shipped in Precise Pangolin 12.04 and was based on the v3.2 upstream Linux kernel. Other notable changes with the Quantal Alpha-1 kernel include the transitioning of the i386 generic-pae flavor to become the generic flavor offering, collapsing of the virtual flavor back into the generic flavor, and homogenizing the entire linux-meta package. We also see the arrival of a new highbank arm server kernel flavor.
GCC4.7In Quantal Alpha-1, the 4.7 version of GCC is replacing the 4.6 version that was included in Ubuntu 12.04 LTS.
The default toolchain is now made of: GCC 4.7, binutils 2.22, eglibc 2.15, and Linaro gdb 7.4-2012.04.
Python3.0For 12.10, we intend to ship only Python 3 with the Ubuntu desktop image, not Python 2. Alpha-1 begins this process, with the installer and some other applications ported to Python 3. There are still quite a few packages left to port, and so Python 2 and 3 are both installed for the time being.
