I have switched jobs! still doing bioinformatics but for a service company providing next gen sequencing. Hence I think I shall move to a new blog address its here at http://kevin-gattaca.blogspot.com/ if its still relevant to you
installed gnome-do and avant-window-navigator
trying to figure compositing.. hmm good that metacity does compositing!
The quirks of my spanking new Ubuntu install is driving me nuts..
I found solutions online that do not seem to work!
1) I have to alt-tab twice to change windows (the first just shows the popup)
but it seems that using compositing or adding visual effects solves the problem!
2) Alt_R doesn’t work! its a special mod key but xmodmap doesn’t help!
Any solutions is appreciated!
Finally made the move!
My old version was no longer supported (read respository servers are gone!)
I needed a bit of house cleaing (read I have files which i have no use for and don’t know if i shld del)
so the move was needed.
I wanted to use LTS (long term support)
but by a twist of fate i ended up with 9.04 amd64 no less (to make use of the 16gb ram that i got)
I must say the upgrade IS an upgrade. the graphics are slicker and more imptly they are faster!
the migration went well. So far I didn’t have to recustomize most of my settings. Just copying the profiles sorted everything.
but have the usual hiccups of having to reinstalling
- sun java 6
- flock-browser (why can’t i just copy it over?? had to get the deb from http://www.getdeb.net/)
- gnome-vim (why doesn’t this ship with ubuntu as default?)
- 64bit flash player (hmm haven’t gotten down to this yet)
But I must say the advantages are
- better support for HP network printers (yeah! no more manual setups with IP addresses)
- Google-chrome works!
- did I mention again that its faster and slicker?
after looking at gOS I might even fiddle to get a Mac look just to be the envy of my less techy frens
so far I haven’t met a prob like nsaunders.. with upgraded packages but will keep a note for his method
Wished I could have been there.. would love to c what tools are lacking for next gen seq technologies.
Had to use bash to run a few one off jobs or edit my bash_profile for enviroment settings..
these are useful links!

will post experiences on an Ubuntu box later
The problem that needed solving this time was having a list of filenames of my ab1 files, location( directory path) and a md5sum so i know if duplicate filenames are the same file or just a result of misnaming.
managed to come up with this after copying from two different scripts
one that was used to make an inventory of a directory of ogg songs and the other a python equivalent of md5sum check in linux.
