Written by two Debian developers — Raphaël Hertzog and Roland Mas — the Debian Administrator’s Handbook started as a translation of their French best-seller known as Cahier de l’admin Debian (published by Eyrolles).
It’s a fantastic resource for all users of a Debian-based distribution.
Accessible to all, this book teaches the essentials to anyone who wants to become an effective and independant Debian GNU/Linux administrator.
Given that traditional editors did not want to take the risk to make this translation, we decided to do the translation ourselves and to self-publish the result. After a successful crowdfunding campaign, we managed to complete this translation between December 2011 and May 2012.
To live up to our free software ideals, we wanted the book to be freely available (that is under the terms of a license compatible with the Debian Free Software Guidelines of course). There was a condition though: a liberation fund had to be completed to ensure we had a decent compensation for the work that the book represents. This fund reached its target of €25K in April 2012.
Yesterday I was reading some friends’ RSS feed when I found this nice resource for us little geek around on the topic of berver’s rack mounting and management. If you too are into this world don’t miss the chance to bookmark/follow these guys!
It’s been a hard day’s night, and I’ve been working like a dog
It’s been a hard day’s night, I should be sleeping like a log
If you didn’t hear me, or saw some of our websites going down now you can safely guess why …
Are you a power-user with 5 minutes to spare? Do you want a faster internet experience?
Try out namebench. It hunts down the fastest DNS servers available for your computer to use. namebench runs a fair and thorough benchmark using your web browser history, tcpdump output, or standardized datasets in order to provide an individualized recommendation. namebench is completely free and does not modify your system in any way. This project began as a 20% project at Google.
namebench runs on Mac OS X, Windows, and UNIX, and is available with a graphical user interface as well as a command-line interface.
Here is what the nameserver overview looks like:
Here are what some of the graphs produced look like:
P.S. = there’s a command-line version too!
This video is REALLY funny!
Perlbrew is a tool to manage multiple perl installations in your
$HOMEdirectory. They are completely isolated perl universes. This approach has many benefits:
- No need to run
sudoto install CPAN modules, any more.
- Try the monthly released new perls.
- Learn new language features.
- Test production code.
- Leave vendor perl (the one that comes with OS) alone
- Hacking perl internals.
- Just to keep up with fashion.
While the default is good enough, you may customize it to install to alternative places, or even let multiple users share the whole perlbrew environment.
Moving your home directory
Don’t email me for help. This is an advanced maneuver, you’re on your own!
Go into, and select the account you’d like to move; click the lock to unlock.
Chooseby right-clicking or control-clicking on the account you want to relocate:
Next, copy your home directory to the desired location, then change it using thebutton as shown below. Don’t mess with anything here unless you really know what you are doing.
Do not forget—
- After making these changes, immediately reboot, then REMOVE your original home directory to avoid confusion.
- Don’t forget to create another admin account that resides on the boot drive, so that you login if your regular account is on a volume that “goes away”.
I am in the middle of the work for a GNU/Linux keynote & hands-on demo for some colleagues.
Everything went ok during the installation until first reboot on which the system told me:
FATAL: INT18: BOOT FAILURE"
remaining into the error mode and forcing me to manually reboot.
If this happens to you too be sure to check if the installation media (the cd-rom or the dvd-rom) is still present in the player (!!!) and remove it.
It happears to be a know issue with VirtualBox, since a bug #2680 was opened 3 years ago and still unresolved (probably because it’s unclear if it’s VirtualBox or Fedora dvd boot system fault).
Ejecting the optical media solved my issue, cheers!
