Cheeky and stupid bot …
The bot with user agent Linguee Bot (http://www.linguee.com/bot; bot@linguee.com) just downloaded approximately 2 GiB of stuff from a ViewVC-listing on one of my servers. Just because it’s stupid, but also because it’s so cheeky to ignore robots.txt. So be it. … Continue reading
How to get English error messages on a localized Ubuntu?
Have you ever noticed that oftentimes people in anglophone forums will almost be offended if someone quotes an error message in their local language? Well, on one hand I can understand it, on the other I see more value in … Continue reading
Clever indeed
Just for giggles and some test I installed Kubuntu in Russian and it turns out that the “Д/н” prompts can also be acquitted with y or n as one would expect. Otherwise I would have been in a kerfuffle as … Continue reading
Tmux is great … (but how to build on Lucid Lynx?)
… only a few troubles to get it to build on Ubuntu 10.04 LTS Basically you’ll want libevent2, which doesn’t come in the package repos, so fetch it from here. Then you obviously fetch the tmux source via tmux.sourceforge.net and … Continue reading
SSL error with a newly signed cert?
Last night I literally spent hours figuring out an alleged issue with the certificate from StartCom. Of course the problem was entirely on my end, in the editor to be precise. But what happened? I fetched ca-bundle.pem and entered it … Continue reading
Highly useful: ddrutility
During a rescue mission I encountered read errors on both hard drives of a degraded RAID. Since most commercial end-user tools limit your flexibility I went for Ubuntu Rescue Remix 12.04 in order to use ddrescue. However, to my delight … Continue reading

Raspberry Pi shipping …?
Seems the first batches went to Farnell and RS. I registered my interest at RS already, let’s see. Seems like the demand is way above supply, so it’s pure chance. Besides, it appears that they sell only one per person … Continue reading
prune-kernels function …
If you are like me, you will have noticed on Ubuntu (and sometimes Debian) that stale old kernels remain on the disk even when they aren’t needed anymore. I wrote a little Bash function to get rid of those kernels. … Continue reading
Selecting the editor on Debian/Ubuntu non-interactively
Set the selected editor on Ubuntu/Debian for yourself and root in one line: echo ‘SELECTED_EDITOR=”/usr/bin/vim.nox”‘|tee $HOME/.selected_editor| \ sudo tee /root/.selected_editor or echo “SELECTED_EDITOR=\”$(which vim.nox)\”"|tee $HOME/.selected_editor| \ sudo tee /root/.selected_editor // Oliver

CVS and SSH on a very old machine …
Had trouble getting it to work with ancient versions of ssh (OpenSSH_3.1p1) and cvs (Concurrent Versions System (CVS) 1.11.20). Until I figured that I could write a little wrapper script to see what’s wrong. The wrapper script looked like this: … Continue reading
Re: Oracle bought ksplice … and apparently the source was pulled
I contacted one of the good people from ksplice (I’ve got an active subscription) and got pointed to oss.oracle.com/ksplice/software/ Unfortunately the access to a distributed version control is gone for good, it seems.

FLOSS not sustainable for companies?
A few weeks ago I reported about ksplice whose Git repository had disappeared. Now the same happened for Likewise Open which was bought by BeyondTrust. After renaming the repository and moving its location from git://git.likewiseopen.org/likewise-open.git to git://git.likewiseopen.org/bt-identity-open.git it now also … Continue reading
Oracle bought ksplice … and apparently the source was pulled
The source used to be at http://www.ksplice.com/git/ksplice.git, but now they pulled it. Only the disassembler library is now left. For now, here’s the download: 221b2b27906c76ac77b375c64dce9963 ksplice-git-backup.tgz // Oliver

Something I’ve been looking for for some time now: cat /proc/cmdline
nullmailer-queue: Could not write envelope sender
Less than obvious reason, /var ran out of disk space. And /var/spool is located on that volume.

beroot
… don’t confuse with reboot alias beroot=”sudo su -l root -c \”$(which bash) –rcfile $HOME/.bashrc\”" I like to feel home in my environment, even when I assume root rights. Since not everyone likes my .bashrc file in scenarios where the … Continue reading

Installing php5 on Ubuntu requires apache2?
When I wanted to install lighttpd today I added php5 to the apt-get install. But then it would tell me that apache2 and numerous other packages would also get installed. Turns out that instead of php5 I actually wanted php5-cgi. … Continue reading
Little annoyance
Lately in Ubuntu 10.04 I got upon login two times the output about the number of packages available to be updated. One of them always outdated. I have long tried to find the reason and finally managed to. The problem … Continue reading
