natronWorking on Linux but searching for some good software for your work ?

Now you have a new and powerful tool available for linux: Natron.

Natron is a free and open source video compositing software, similar in functionality to Adobe After Effects or Nuke by The Foundry.

The project is a free (Mozillla Public License v2) node-based compositor that relies on OpenColorIO for color management, OpenImageIO for file formats support, and Qt for user interface. It also works with 32bit float per channel precision and supports OFX plugins, both free and commercial.

Natron was started last year at Inria, a public science and technology institution that unites several research centres in France. Alexandre Gauthier, the lead developer of Natron, got the required funding from the institution, and last December he additionally won a “Boost Your Code” contest at Inria that offered him 12 months of paid development. In May this year, Alexandre presented the project at Libre Graphics Meeting in Leipzig.

lanius announce
Faster Than Light was one of my favourites games for 2013, and now they have just released a free expansion : Advanced Edition.

FTL: Advanced Edition is a major update that adds features to the original and is a free download for players who already own the original. It was released on Thursday, April 3, 2014

Faster Than Light (more commonly known as FTL) is a top-down, real-time strategy game on Steam, made by indie team Subset Games. The player takes control of the crew in a space vessel that’s in possession of critical information that must be delivered to an allied fleet several sectors away. However, to make the game more challenging, you are pursued by a large rebel fleet in every sector.

In keeping the story simple, the team has been able to create an in depth management system. You must maintain the ship when it’s damaged and make difficult decisions when under attack. For example, jumping in the middle of battle or taking energy from one source to power a weapon.

Jumping is how the player moves through the game, and, in some circumstances, the player may be near death, but can still escape battle. You will, of course, have encounters with the rebels. These are real-time, ship-on-ship battles which are the core of Faster Than Light’s gameplay, and, on quite a few occasions, the tension is increased through forcing you to make split-second decisions at every turn.

Article by me, first published on Openlogic.com

Whether you are a system administrator or a developer, sometimes you need to consider the use of memory in GNU/Linux processes and programs. Memory is a critical resource, and limited memory plus processes that use a lot of RAM can cause a situation where the kernel goes out of memory (OOM). In this state Linux activates an OOM killer kernel process that attempts to recover the system by terminating one or more low-priority processes. Which processes the system kills is unpredictable, so though the OOM killer may keep the server from going down, it can cause problems in the delivery of services that should stay running.

In this article we’ll look at three utilities that report information about the memory used on a GNU/Linux system. Each has strengths and weaknesses, with accuracy being their Achilles’ heel. I’ll use CentOS 6.4 as my demo system, but these programs are available on any Linux distribution.
