KernelPanic Luckily this problem don’t happen so frequently, at least using stable kernel and distributions, but sometime your beloved Linux could go in “Kernel Panic”.

A kernel panic is an action taken by an operating system upon detecting an internal fatal error from which it cannot safely recover. The term is largely specific to Unix and Unix-like systems; for Microsoft Windows operating systems the equivalent term is “stop error” (or, colloquially BSOD “Blue Screen of Death”).

The kernel routines that handle panics, known as panic() in AT&T-derived and BSD Unix source code, are generally designed to output an error message to the console, dump an image of kernel memory to disk for post-mortem debugging and then either wait for the system to be manually rebooted, or initiate an automatic reboot.

The default it’s to wait, so if this happen on one of your servers and you don’t notice it all its services could stay down for some time, while using an automatic reboot the problem could be solved quickly.

What’s your upload and download speed at home (or in your office) ?
Are you really sure that you get what do you pay for to your ISP ?

To test the speed of our internet connection There are several internet services such as SpeedTest a web service that is available both from Web browsers and mobile application.

Now you can easily check it also with speedtest_cli a command line interface for testing internet bandwidth using speedtest.net. In this way you can do the test also on servers that don’t have a Browser or a graphical interface. Continue reading »

First of all, Zorin team, Linux notes from DarkDuck and Linuxaria would like to say THANK YOU to all the participants of the contest that we ran for last few weeks. It was a real pleasure to see such a response, and to read all your article. As you probably know the winner have been announced in another post and today I want to publish some of the best articles that we’ve received.

So have fun in reading these article of other Linux users.

A hard link is actually nothing more than a regular directory entry, which in turn can be seen as a pointer to the actual file’s data on the disk. The cool thing about hard-links is that a file can be stored once on the disk, and be linked to multiple times, from different locations/entries, without requiring to allocate extra disk space for each file instance.

But then a question arises: Given a specific file on disk, how can someone know whether it is linked to by other directory entries or not? This can be easily answered using the ls command:

giannis@zandloper:/etc$ ls -l passwd
-rw-r--r-- 1 root root 1402 2008-03-30 17:49 passwd
;

Do you ever wonder what is this small number between the file permissions and the owner in the output of ls’s long listing format (its value is usually “1″ for files, or “2″ for directories)? This number is actually the link-count of the file, when referring to a file, or the number of contained directory entries, when referring to a directory (including the . and .. entries).

Garry’s mod is one of the most sold games for Linux on Steam, so I’ve decided to publish this review of the game, first published on devtome.com 

Garry’s Mod, developed by Facepunch is without a doubt one of the most enjoyable and hilarious games that I have ever played. Out of the box, the game is perhaps one of the ultimate sandbox games available anywhere. You spawn in the middle of an open area that you choose and you can spawn in just about any item or NPC that you can think of. This game is also probably one of the best physics simulators available. The entire game revolves around physics. In this game you are able to do whatever you heart desires and although I say that with a lot of different games, I truly mean it with Garry’s Mod. Whatever you want. If you want to build an airplane out of a bathtub and some planks of wood, then be my guest. You can simply spawn in the materials that you want and then use tools to “weld” them together. Using weight tools you can make these items very light, which will allow them to become airborne. This game definitely deserves lots of praise.
