Min kone mindede mig lige om at jeg skulle huske at blog'e om vores oplevelse med Emma's vand i ørerne og hvordan vi fik det løst, uden at få opereret dræn ind.
Vi konstaterede for nylig, at vores ældste datter, Emma på 2½ år var begyndt at blinke på højre øje og min kone tog hende til en øjenlæge.
Øjenlægen forsøgte først at få ét apparat til at fungere, men måtte give op og bruge et andet, iflg. ham gammeldags, apparat. Herefter konstaterede han straks at Emma var langsynet og skulle have briller. Det var bare et spørgsmål om hvilken styrke hun skulle have og vi fik en tid hos en der skulle foretage præcis måling af øjet for at vurdere den nødvendige styrke.
I've often heard people say that you should use #!/bin/sh in your shell scripts to ensure they run everywhere.
I always use /bin/bash - because I like the bash-specific features and wouldn't like to live without, and I don't have a list in hand that shows me which "features" I can't use if using /bin/sh - so I can't be sure my script actually works on generic /bin/sh - without testing.
Having to configure 17 servers that have to be absolute alike and other such details, made me setup puppet to do the job. I've used cfengine before, so I was looking forward to using puppet for a larger project and see if it made me as happy as I'd hoped (compared to using cfengine which can be a bit tedious :)
The general goal is that everything is setup up by puppet, so that the restore plan is as simple as possible:
I wanted to check for age of certain .lock files from scripts, so I can catch if a certain script has been running for too long (or has died without removing the .lock file). In this instance it was a script that runs drupal cronjobs and to be sure that it doesn't run multiple times, the script throws a lock file while it is running.
It turns out that check_file_age in standard nagios-plugins worked beautifully, except for one little annoying detail - it returns CRITICAL if the file does not exist :(
I have been working with a client on setting up multipath for some Linux database hosts, with a NetApp FC Backend. They wanted to use Ubuntu 8.04 and after mucking a bit with the official config from NetApp (had to change path_checker to directio as readsector0 does not work on Ubuntu, and disable priority check as this doesn't work either :( )
Ubuntu then saw the 4 paths, but as we soon discovered, it returned IO errors if just 1 path failed, which made the kernel remount read-only :(
I am working on setting up a proper handling of logs from many hosts.
I want unexpected log entries from any host, to be noticed immediately (via an alert in Nagios) and I want the alert to go away, as soon as the log entry has been handled as needed (added to ignore filter, issue fixed, task assigned for later fixing etc.).
En sjælden gang imellem, får jeg (eller dvs. http://linuxpusher.dk ) en god morgen hilsen a la denne her:

why are you selling software that is free,
I've been working on how best to convert our instructional videos for www.virkpaanettet.dk (CMS homepages) from the original ogv format to flv (flash) videoes to put on the site.
After having used ffmpeg, as many examples prescribe, I finally found an example, using mencoder which works a whole lot better than the ffmpeg versions I have tested.
I(or my wife) record using gtk-recordmydesktop in a 1024x768 resolution - as the website needs to be fully visible and most designs are optimized for that screen size.
Jeg skulle lige checke om blog.kramse.dk har en IPv6 addresse (også kaldet en AAAA addresse i dns sprog).
Hvis jeg laver et host opslag (med bind9's version af host) på blog.kramse.dk's A addresse følger host programmet dennes CNAME entry til www.kramse.dk (uden at sige noget om det iøvrigt) og giver mig dens A.
