  • TT – Treacherous Technology

    So, after a failed upgrade to Ubuntu 7.04 Feisty Fawn I was left with no choice but to boot into my Windows 2003 partition. (To Ubuntu’s defense: 7.04 is clearly marked as beta software and I was doing the update on my own risk). Just to be clear: this Windows 2003 SBS is a 100%…

  • Linux tips

    I am and will be very short of time for a couple of weeks, so most probably these will be the last posts for the month. If you’ve read and followed my advice on re-creating the swap partition after failed hibernation, there is one caveat I discovered: after recreating, the swap partition is not automatically…

  • Two quick Linux / Ubuntu tips

    If you find that you are running out of disk space and some of your applications crashed recently, you might want to look in your home folder. When applications crashes, Ubuntu creates here memory dumps to help the programmer determine the cause of the crash. But if you are no programmer, you can safely delete…

  • Linux command line options

    Being a Linux newbie, I’m always looking for tips and tricks related to this new OS I’m learning. Here is an article from IBM, via Slashdot: Learn 10 good UNIX usage habits

  • How to know what you’ve installed?

  • Do NOT simplify when you are explaining!

    Or at least make it very clear when you do so! Simplifications and metaphors are very dangerous because they hide some detail deemed non-important by the person who is using them. But you can’t know in which context your explanation will be read (if you are posting it on the Internet), so be sure to…

  • Moving to Ubuntu – The Regex Coach

    After reaching 21 posts and caching up with the Security Now! episodes, I thought that it’s time to start a new series. I am what I consider a pro Windows user and lately I started moving to Ubuntu. I toyed with Linux distros before, but this is the first I feel that I can learn.…

  • Hack the Gibson – Episode #56

    Read the reason for these posts. Read Steve Gibson’s response. Here I am again, as promised. I won’t turn soft because of a nice e-mail. (Then again I hope that these posts are of technical nature, they point out objective mistakes and don’t become a personal attack. If you think that I’m sliding in that…

  • Traceroute on Windows and Linux

    Did you know that the Linux version of traceroute uses UDP packets with various TTLs instead of ICMP echo requests by default? I sure didn’t, but thinking about it is a very smart way to do it. My only question would be: doesn’t this interfere with the operation of a server if you happen to…
