Working 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.

Switching to Linux, Checklist

Linux often seems like a breath of fresh air to Windows users. It’s free. It doesn’t have bloatware issues. You don’t have to pay for it. It has less malware and hacking issues because it’s less profitable and productive for the baddies to concentrate on an operating system with less users.

Did I mention it doesn’t cost anything?

Whatever the reason Linux looks good to you, you have to remember that Linux and Windows are two different animals. Windows is far more professionally polished and noob friendly. (It has to be. You paid for it.) While there are a few supported versions of Windows floating around, most users stick with the one that comes with their machines. On the hand, Linux has so many distributions, it’s hard to keep track sometimes. From the way you install programs to the amount of time you spend in a command prompt screen, it’s a different experience. Whether it’s a good experience or not depends on your preference.

Linux: Timeouting commands in shell scripts

Often you want to automatize something using shell scripting. In a perfect world your script robot works for you without getting tired, without hick-ups, and you can just sit at the front of your desk and sip coffee.

Then we enter the real world: Your network is disconnected. DNS goes downs. Your HTTP hooks and downloads stall. Interprocess communication hangs. Effectively this means that even if your script is running correctly from the point of operating system it won’t finish its work before you finish your cup of coffee.

How to check if you are vulnerable to shellshock

The most new and dangerous bug around it’s the one called “shellshock”, this is a security bug in the widely used Unix Bash shell which was disclosed on 24 September 2014. Many Internet daemons, such as web servers, use Bash to process certain commands, allowing an attacker to cause vulnerable versions of Bash to execute arbitrary commands. This can allow an attacker to gain unauthorized access to a computer system.

The bug causes Bash to unintentionally execute commands when they are stored in specially crafted environment variables. Within days, a series of further related vulnerabilities in Bash were found, leading to the need for further patches.

By 25 September, botnets based on computers compromised with this exploit were being used by attackers for distributed denial-of-service attacks and vulnerability scanning, source wikipedia

Let’s see how to check if your computer or server is vulnerable.

Linux Games: Sanctum 2

I’ve recently bought an offer for Sanctum 2 on Steam, and while at the start I was a bit skeptic, I must say that I like this mix between a Tower Defense and an FPS.

Sanctum 2 is the sequel to the world’s first Tower Defense/FPS hybrid game
Pick from four unique character classes and take up the mission of protecting the Cores from hordes of mysterious aliens. In Sanctum 2 you play your character exactly the way you want through the new and extensive customization system. Pick your own loadout of towers, weapons and perks, and pick well, because you are humanity’s last defense against the hordes set out to destroy it.

The normal cost of the complete bundle that includes the game + 5 DLC it’s around 23 € on Steam, but if you like it I suggest to put it on your wishlits and wait for some offer, the game it’s a bit old and so offers should be frequent, I got it with a discount of the 70%

The game has a great graphics, still it’s playable on my crappy computer, and both the solo campaign and the online co-op multiplayer are funny enough, so let’s see now some detail about this game:
