This is just a quick notice that during the last five days there was a problem with the website feeds. The web server returned a 500 Internal Server Error to almost all requests for /feed/ URLs. Also, there was a big increase of the server’s CPU load behind the scenes, which was caused by php-cgi…
I can still recall the excitement of the first time I tried to access and administer a remote system using SSH. Accessing my shell at a remote machine securely, being able to do local and remote port forwarding in order to access remote services through encrypted tunnels, X forwarding, secure file transfers using scp or…
If you’ve tried out several wiki engines, you have probably noticed that the developers of each of them have invented their own wiki markup language. I guess no-one has a problem with that. It’s a free world after all. However, all these different versions of markup languages easily become a pain when you have to…
I still haven’t figured out whether it happened because of pure stupidity, temporary brain malfunction or low caffeine concentration in the blood, but a week ago, by mistake, I wiped the MBR of my primary desktop’s hard disk and also (because, you know, the MBR alone is never enough!) the boot sector of the first…

Mozilla has announced the general availability of version 3 of its popular open source email & newsgroup client, Thunderbird. Thunderbird has been my desktop email client of choice since its early stable releases, both in Linux and Windows. Actually, the only programs I’ve ever used for email and newsgroup management are Outlook Express, Mozilla Thunderbird…
During the last weekend, I made some changes to the website’s feeds. It seems that, after 4 years of blogging, I have finally made up my mind about what is needed and what is unnecessary regarding the syndicated content on G-Loaded.
I’ve been looking for a pure python implementation of the ping command. Now that I found one, I am not sure if I want to use it, as it has a restriction: only privileged users can ping other hosts. I’ve used the ping command successfully as a normal user on all operating systems I have…
setenforce is a command line utility that is used to switch the mode SELinux is running in from enforcing to permissive and vice versa without requiring a reboot. Lately, I’ve started experimenting again with SELinux on a live system. The default targeted SELinux policy, as usual, needs some adjustment to work with a custom server…
