Blender, an open source 3D content-creation program, has recently reached the 2.75 release, which features AMD OpenCL rendering and fully integrated stereo/multiview support.
Blender Foundation and developer community announced the release of Blender 2.75 on July 1st. The main highlights of this release are:
Blender now supports a fully integrated Multi-View and Stereo 3D pipeline
Cycles has much awaited initial support for AMD GPUs, and a new Light Portals feature.
UI now allows font previews in the file browser.
High quality options for viewport depth of field were added
Modeling has a new Corrective Smooth modifier.
The Decimate modifier was improved significantly.
3D viewport painting now supports symmetry and the distribution of Dynamic Topology was improved
Video Sequence Editor: Placeholders can now replace missing frames of image sequences
Game Engine now allows smoother LOD transitions, and supports mist attributes animation
And: 100s of bug fixes and smaller feature improvements.
Since the official package is not well integrated with Ubuntu desktop, you can alternatively install Blender from Thomas Schiex’s PPA, and receive future updates through Software Updater.
To do so, run below commands one by one in a terminal (Ctrl+Alt+T) window:
Note that there might be a small delay before a new release to be made into the PPA. You may check out the PPA web page for the Blender version.
In addition, to associate .blend files with Blender go to file’s context menu (right-click menu) -> Properties -> Open With tab -> select Blender software from the list and finally click the Set as default button.
XFCE4 desktop now has a hot-corner panel plugin that provides an easy way for users to set hot corner action, though there’s already a Gnome app brightside works on Ubuntu with Xfce.
XFCE4 HotCorner Plugin is a new project created one week ago. It currently supports the following operation in primary display:
xfdashboard
toggle desktop
start screensaver
turn off monitor
run custom command
It also provides an option to disable hot corner when active window is fullscreen.
Install HotCorner Plugin in (X)Ubuntu:
This plugin requires XFCE 4.12. For (X)Ubuntu 14.04 and (X)Ubuntu 15.04 and Mint 17 users who are still running with old Xfce desktop, you may first read this guide to upgrade to Xfce 4.12
To install the plugin, select download one of below packages that matches your OS type (32-bit=i386 or 64-bit=amd64)

A simple and beautiful WhatsApp desktop client has been created recently, available for Linux, Windows, and OS X. It’s an open-source and unofficial client based on WhatsApp Web.
Besides the basic WhatsApp features (e.g., group chats, send photos & videos, and share locations), this unofficial WhatsApp for desktop also features:
Badge with the number of notifications in the dock/taskbar (OS X and Windows)
Auto-launch on OS startup (OS X, Windows)
Native notifications (all platforms)
System tray icon (OS X, Windows)
Open links in browser or new window
Preferences in the right-click context menu (or menu bar for OS X, tray menu for Windows)
unofficial whatsapp client on all platforms
Install WhatsApp for Desktop in Ubuntu:
Before installing this software, you may first read the following DISCLAIMER from its project page:
This project does not attempt to reverse engineer the WhatsApp API or attempt to reimplement any part of the WhatsApp client. Any communication between the user and WhatsApp servers is handled by WhatsApp Web itself; this is just a native wrapper for WhatsApp Web, more akin to a browser than any WhatsApp software.
To install it, select download linux32.deb or linux64.deb that matches your os type (32-bit or 64-bit) from the link below and then click install via Software Center or Gdebi package installer.
Linux Kernel 4.1, a new kernel series, was released over the night by Linus Torvalds. He wrote on the Linux kernel mailing list:
So after a *very* quiet week after the 4.1-rc8 release, the final 4.1 release is now out.
I’m not sure if it was quiet because there really were no problems (knock wood), or if people decided to be considerate of my vacation, but whatever the reason, I appreciate it. It’s not like the 4.1 release cycle was particularly painful, and let’s hope that the extra week of letting it sit makes for a great release. Which wouldn’t be a bad thing, considering that 4.1 will also be a LTS release.
Anyway, since rc8 we’ve had truly small changes, mainly some final driver fixups (HDA sound, drm, scsi target, crypto) and a couple of small misc fixes. The appended shortlog is probably one of the shortest ones ever. I’m not complaining.
And this obviously means that the merge window for 4.2 is open.
Linus
What’s New in Kernel 4.1:
Some of highlights for the Linux 4.1 kernel (by Michael Larabel):
Significant performance improvements for certain hardware as well as power consumption/efficiency improvements for select Intel hardware.
Nouveau ships with GeForce GTX 750 acceleration support that doesn’t require the manual extracting/setup of any non-redistributable firmware blobs.
Intel XenGT vGPU support for those wanting Intel graphics acceleration support from Xen guests. The KVM support is still being developed.
Radeon DisplayPort MST support.
EXT4 file-system encryption thanks to work done by Google in looking to add file-system-level EXT4 encryption for Android.
Better RAID 5/6 support with MD RAID.
Improved laptop support from major vendors along with better Chromebook Pixel 2 support.
Continued bring-up of Intel Skylake support within Linux. Skylake is still on course for launching later this year.
ACPI support for AArch64 / 64-bit ARM.
Many other changes.

Noise, the official music player of Elementary OS, is a fast and beautiful GTK3 audio player with a focus on music and libraries. It handles external devices, CDs, and album art. Noise utilizes Granite for a consistent and slick UI.
Elementary OS Team has created a few PPAs on launchpad.net so users can easily install and test some Elementary applications on Ubuntu desktop. And here’s how to install Noise music player in Ubuntu 15.04, or Ubuntu 15.10.
Noise in Ubuntu 15.04

4. (Optional) If you want to remove this music player, simply run:
sudo apt-get remove noise
Tip: Due to a bug related to the Unity overlay scrollbars, there’s a background issue which can be fixed by running below command to edit the launcher file of Noise:
Install gksu from Software Center if the command doesn’t work. When the file opens, change the value of Exec to env LIBOVERLAY_SCROLLBAR=0 noise %U so it look likes:
MuPDF is a small, fast, and yet complete PDF viewer that supports PDF 1.7 with transparency, encryption, hyperlinks, annotations, searching and more. It also reads XPS and OpenXPS documents.
The renderer in MuPDF is tailored for high quality anti-aliased graphics. It renders text with metrics and spacing accurate to within fractions of a pixel for the highest fidelity in reproducing the look of a printed page on screen.
MuPDF is available in Ubuntu repositories by default, but Canonical does not provide updates for this software. While Ubuntu Software Center provides the 1.6 (or older) release, the latest MuPDF 1.7a was released in last month with below changes:
Fixed bug that allocated too much memory when packing paths.
Fixed EPUB font scaling bug.
Fixed EPUB file type handling in viewers.
Improved tolerance for broken and unsupported CSS.
Added -z option to mutool clean.
Install MuPDF in Ubuntu:
1. Open terminal from the Dash, Application Menu, or by pressing Ctrl+Alt+T on keyboard. When it opens, run command to add PPA:
sudo add-apt-repository ppa:ubuntuhandbook1/apps
2. After adding the PPA, open Software Updater to automatically check for updates
After checking for updates, you’ll see MuPDF in the list available for upgrade if you have a previous version installed.
If you don’t have a previous release installed in your system, install it via Synaptic Package Manager or by running below command in terminal:
sudo apt-get install mupdf mupdf-tools
Once installed, open PDF/XPS files using MuPDF from their context (right-click) menu. For key bindings and other options, run man mupdf in terminal.
To set MuPDF as default viewer, go to PDF file’s context menu -> Properties -> Open With tab -> select the viewer from list and click Set as default button.
