The support period is now nearing its end and Ubuntu 12.04 will reach end of life on Friday, April 28th. At that time, Ubuntu Security Notices will no longer include information or updated packages for Ubuntu 12.04.

These updates are delivered in a secure, private archive exclusively available to Ubuntu Advantage customers.
All Ubuntu 12.04 LTS users are encouraged to upgrade to Ubuntu 14.04 LTS or Ubuntu 16.04 LTS. But for those who cannot upgrade immediately, Ubuntu 12.04 ESM updates will help ensure the on-going security and integrity of Ubuntu 12.04 systems.

Nvidia has just announced a new version of graphics driver 343.22 for Linux with new GPUs support and various fixes.
According to the release highlights, Nvidia 343.22 added support for GeForce GTX 970 and GTX 980, removed support for G8x, G9x, and GT2xx GPUs, and motherboard chipsets based on them. Ongoing support for new Linux kernels and X servers, as well as fixes for critical bugs, will be included in 340.* legacy releases through the end of 2019.
The new drive contains various fixes and/or new features:
Fixed a bug that prevented the “sync to vblank” setting from being honored for EGL applications.
Fixed a bug that could cause some OpenGL programs to encounter out of memory during a mode switch.
Fixed a bug that prevented the NVIDIA OpenGL driver from honoring the __GL_SHADER_DISK_CACHE_PATH environment variable.
Fixed a bug that caused disabled displays to be implicitly included in the target selection for some queries and assignments on the nvidia-settings command line interface, in the absence of any explicit target selection.
Added a new attribute to the NV-CONTROL API to query the current utilization of the video decode engine.
Fixed a bug where the Exchange Stereo Eyes setting in nvidia-settings didn’t work in certain stereo configurations.
Worked around a Unigine Heaven 3.0 shader bug which could cause corruption when tessellation is enabled by implementing an application profile that uses the “GLIgnoreGLSLExtReqs” setting. See the documentation for the __GL_IGNORE_GLSL_EXT_REQS environment variable for more details.
Fixed a memory leak when destroying EGL surfaces.
Added support for multiple simultaneous EGL displays.
Fixed a bug that could cause nvidia-installer to unsuccessfully attempt to delete the directory containing precompiled kernel module interfaces, on packages prepared with –add-this-kernel.
Updated nvidia-installer to log uninstallation to a separate file from the installation log, and to attempt uninstalling previous driver installations using the installer program from the previous installation, when available.

This simple tutorial shows how to install Gnoduino IDE, implementation of well-known Arduino IDE for GNOME, in Ubuntu 14.04 & Ubuntu 12.04.
Why Gnoduino?
The original Arduino IDE is written in Java however, and that makes for poor integration on the Linux platform, particularly with Ubuntu Unity. Luckily enough someone has been busy to do a simple rewrite of the original IDE in Python and GTK, making a fully Linux native IDE, and it’s called Gnoduino. This implementation is targeted at GNOME and its purpose is to be light.
How to Install Gnoduino IDE in Ubuntu:
Besides building from source, the IDE is available in PPA for Ubuntu 14.04 and Ubuntu 12.04.
Press Ctrl+Alt+T on keyboard to open the terminal. When it opens, paste the command below and hit enter to run. Type in your password when prompt.
For Ubuntu 14.04, Ubuntu 12.04 and their derivatives, press Ctrl+Alt+T on keyboard to open terminal. When it opens, run the commands below one by one to get this release from PPA:
