Tor Browser 4.5.1 released, Install on Ubuntu 15.04 vivid Vervet, ubuntu 14.10 Utopic Unicorn / Linux Mint via PPA

Tor Browser Bundle is a free and platform-independent application designed to allow users to browser the Web anonymously through the powerful Tor network on the Linux, Microsoft Windows and Mac OS X operating systems, without the need to use any third-party software.

The Tor software protects you by bouncing your communications around a distributed network of relays run by volunteers all around the world: it prevents somebody watching your Internet connection from learning what sites you visit, it prevents the sites you visit from learning your physical location, and it lets you access sites which are blocked.

The Tor Browser lets you use Tor on Windows, Mac OS X, or Linux without needing to install any software. It can run off a USB flash drive, comes with a pre-configured web browser to protect your anonymity, and is self-contained.

Features at a glance

It is a portable software, allowing users to use directly from a USB flash drive, running a pre-configured web browser to protect their anonymity. The Tor software is the key component of Tor Browser Bundle, protecting users by bouncing their communications around a distributed network of relays, which are run by volunteers all around the world.

Linux kernel is the essential part of any Linux operating system. It is responsible for resource allocation, low-level hardware interfaces, security, simple communications, basic file system management, and more. Written from scratch by Linus Torvalds (with help from various developers), Linux is a clone of the UNIX operating system. It is geared towards POSIX and Single UNIX Specification compliances.

Features at a glance

Linux comes with powerful features, such as true multitasking, multistack networking, shared copy-on-write executables, shared libraries, demand loading, virtual memory, and proper memory management. Initially designed only for 386/486-based computers, now Linux supports a wide range of architectures, including 64-bit (IA64, AMD64), ARM, ARM64, DEC Alpha, MIPS, SUN Sparc, PowerPC, as well as Amiga and Atari machines.

Nvidia Linux Display Driver 346.72 released, available for Ubuntu, Linux Mint, Pinguy OS, Elementary OS, Deepin, Peppermint, LXLE, Linux Lite, Debian, Robolinux, SparkyLinux, Fedora, CentOS, OpenSUSE, Mageia, OpenMandriva, Arch Linux, Manjaro, ROSA Desktop etc.

Nvidia Linux Display Driver 346.72 released, available for Ubuntu, Linux Mint, Pinguy OS, Elementary OS, Deepin, Peppermint, LXLE, Linux Lite, Debian, Robolinux, SparkyLinux, Fedora, CentOS, OpenSUSE, Mageia, OpenMandriva, Arch Linux, Manjaro, ROSA Desktop etc.

Nvidia Linux Display Driver is a proprietary, yet freely distributed OpenGL video driver that aims to offer support for Nvidia graphics cards on any Linux kernel-based operating system. This version has been designed to be installed only computers supporting the 64-bit architecture. For 32-bit support, see this link. It is a native Linux driver that provides users with only a command-line installer, as well as a settings panel. It’s also the number one choice for gaming users.

What's new in Nvidia Linux Display Driver 64-bit 346.72:

• Fixed a bug causing loss of stereo synchronization in certain Quadro Sync framelock configurations.
• Fixed Pixel Buffer Object operations when row length is less than width. GL_[UN]PACK_ROW_LENGTH can be set to a value lower than the width of the operation being carried out. The OpenGL specification allows for this (the source or destination lines will be overlapping). Previously, our implementation of Pixel Buffer Objects did not support this case and would throw an error.
• Fixed a rare deadlock condition when running applications that use OpenGL in multiple threads on a Quadro GPU.

What Nvidia graphics cards are supported by this driver?

Officially, the Nvidia Linux Display Driver supports a wide range of Nvidia graphics cards, much more than the open source Nouveau driver supports. Most of the ION, ION LE, Quadro Plex, Quadro Sync, GRID, NVS, nForce Professional 3000, Quadro FX, Quadro Blade, as well as all the GeForce series are supported at this time.

How to Download and Install Nvidia Linux Display Driver 346.72

to install Nvidia Linux Display Driver 346.72 on Ubuntu, Linux Mint, Pinguy OS, Elementary OS, Deepin, Peppermint, LXLE, Linux Lite, Debian, Robolinux, SparkyLinux, Fedora, CentOS, OpenSUSE, Mageia, OpenMandriva, Arch Linux, Manjaro, ROSA Desktop etc, open a new Terminal window and bash (get it?) in the following commands:

Download for Linux 32 bit :

$ wget http://us.download.nvidia.com/XFree86/Linux-x86/346.72/NVIDIA-Linux-x86-346.72.run

Download for Linux 64 bit :

$ wget http://us.download.nvidia.com/XFree86/Linux-x86_64/346.72/NVIDIA-Linux-x86_64-346.72.run

How do I install the Nvidia graphics driver?

In order to install the Nvidia Linux Display Driver on your Linux box, you will have to first download the binary package using the “Download” button above, save the run file on your Home directory, open a TTY and execute the “sh ./NVIDIA-Linux-x86-xxx.xx.run” command (without quotes), as root (with sudo), where xxx.xx is the version number.

Keep in mind though, that you will have to install the Linux kernel header packages first! During the installation, you will be asked if you want to manually edit the X configuration file or let the installer do all the hard work. Alternatively, it is possible to automatically configure it by running the nvidia-xconfig command via a Linux terminal emulator after the installation.

Mozilla Firefox 38.0 released, available for Ubuntu, Linux Mint, Pinguy OS, Elementary OS, Deepin, Peppermint, LXLE, Linux Lite, Debian, Robolinux, SparkyLinux, Fedora, CentOS, OpenSUSE, Mageia, OpenMandriva, Arch Linux, Manjaro, ROSA Desktop etc.

Mozilla Firefox 38.0 released, available for Ubuntu 15.04 vivid Vervet, ubuntu 14.10 Utopic Unicorn, Ubuntu 14.04 Trusty Tahr (LTS), Linux Mint 17.1 Rebecca, Linux Mint 17 Qiana, Pinguy OS, Elementary OS, Deepin, Peppermint, LXLE, Linux Lite, Debian, Robolinux, SparkyLinux, Fedora 22, Fedora 21, CentOS, OpenSUSE, Mageia, OpenMandriva, Arch Linux, Manjaro, ROSA Desktop etc.

The Mozilla Firefox project is a redesign of Mozilla's browser component, written using the XUL user interface language and designed to be cross-platform, supporting Linux, Android, Microsoft Windows and Mac OS X operating systems. It is a fast, small and very easy-to-use web browser/navigator/explorer that offers many advantages over other similar products, such as the ability to block pop-up windows and the feature-rich tabbed browsing experience.

Features at a glance

The application offers a well designed graphical user interface that integrates search (powered by Google, Bing, Yahoo, etc.), and industry leading accessibility with Find As You Type - find links and page text by simply typing. As mentioned before, the Firefox browser features comprehensive pop-up controls, which will keep unwanted advertising off your desktop. A tab browsing mode will let you open several pages in a single window, allowing you to load links in the background without leaving the page you're on.

What's new in Mozilla Firefox 38.0:

• New tab-based preferences
• Ruby annotation support
• Share the active tab or window in a Hello conversation - enabled for first half of the beta cycle
• Keep track of articles and blog posts with the Reading List - enabled for the first half of the beta cycle
• Base for the next ESR release.
• autocomplete=off is no longer supported for username/password fields
• RegExp.prototype.source now returns "(?:)" instead of the empty string for empty regular expressions
• Page load times improved by speculative connection warmup
• WebSocket now available in Web Workers
• Implemented srcset attribute and element for responsive images
• Implemented DOM3 Events KeyboardEvent.code
• Mac OS X: Implemented a subset of the Media Source Extensions (MSE) API to allow native HTML5 playback on YouTube
• BroadcastChannel API implemented
• Implemented Encrypted Media Extensions (EME) API to support encrypted HTML5 video/audio playback (Windows Vista or later only)
• Automatically download Adobe Primetime Content Decryption Module (CDM) for DRM playback through EME (Windows Vista or later only)
• Optimized-out variables are now visible in Debugger UI
• XMLHttpRequest logs in the web console are now visually labelled and can be filtered separately from regular network requests
• WebRTC now has multistream and renegotiation support
• copy command added to console

Installation instructions:

Mozilla does not provide a repository for its Firefox browser, but the installation steps are quite easy anyway and should not create difficulties on any Linux distribution.

The latest versions of Firefox are available as pre-compiled libraries via the Mozilla FTP, so we need to download the archive (i386 or i686 for 32 bit systems and amd64 or x86_64 for 64 bit systems), extract  it and run the firefox file. Also, it is advised to remove previous versions of Firefox, move Firefox to /opt and create a symlink, for an easier usage.

The below instructions should work on all the popular Linux systems, including Ubuntu, Linux Mint, Pinguy OS, Elementary OS, Deepin, Peppermint, LXLE, Linux Lite, Debian, Robolinux, SparkyLinux, Fedora, CentOS, OpenSUSE, Mageia, OpenMandriva, Arch Linux, Manjaro, ROSA Desktop etc.
How to install Firefox 38 on 32 bit Linux systems:

$ wget ftp.mozilla.org/pub/mozilla.org/firefox/releases/38.0/linux-i686/en-US/firefox-38.0.tar.bz2

What's new in Linux Kernel 4.1 RC3:

• As you can tell, it's mostly drivers, with a smattering of arch updates (mostly ARM). And a smattering of misc stuff: perf tooling, documentation, filesystems. The infiniband update is a noticeable chunk of the drivers, we had some delayed stuff there due to maintainership changes.
• Nothing particularly scary or worrisome going on, although there are little fixes all over. Some of them are regressions from this merge window, and some of them are older. And some of them are so old that I almost thought "if it's been broken since 2011, and you only noticed now, maybe it could have waited for the next merge window". You know who you are (and others will too, if they read the commit messages - your shame is out there).
