Tuesday I found this article, which made the double think on how fortunate I am to deal (mostly) with OS X or GNU/Linux software distributions…
The quarterly report shows that 74 different programs from 24 different vendors are installed on the average UK PC and 28 of them, just over a third, are from Microsoft.
That third, and the operating systems, are mostly kept up to date with Microsoft’s Windows Update system. But beyond that, there’s another 23 different autoupdate mechanisms for the remaining programs which need to be monitored or managed.
While some programs have auto-update mechanisms with silent updates, other programs which need regular updates require the user to visit the vendor’s web site to check whether an update was needed.
The report notes that around 8.9% of users have unpatched operating systems and estimates that, on average, 6.5% of programs on a PC aren’t up to date. Around 3.4% of programs on the average PC are also end-of-lifed and no longer have security patches available for them.

Reading a Mac mailing list I found a subscriber that asked how to prevent access to the Mail.app application (and so to it’s data) on an iMac shared with four other people on a front desk in an art gallery.
Another user suggested him the usage of MacAppBlocker, from KnewSense Software:
With Mac App Blocker, you can password-protect EACH application on your Mac. Keep your apps and your Mac safe. Set a timeout value to automatically exit the protected application so even when you leave your computer unattended, you’re still protected.
Personally I’ve never been in a situation needing a solution like this one, but I’ve thought about writing down a note on this since one can never know what the future needs will be
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.

Computer Server Rack Facts, Questions and Answers..
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!
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.
namebench was written using open-source tools and libraries such as Python, Tkinter, PyObjC, dnspython, jinja2 and graphy.
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!
I am in the middle of the work for a GNU/Linux keynote & hands-on demo for some colleagues.
Since I’m a loyal Fedora/CentOS user I’m installing the latest Fedora 15 on my MacBook’s VirtualBox.
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!
