For the Meow stuff I drew on the whiteboard, here's [[Ilse's notes|meow-ilse-notes.pdf]] and [[Panos's photo|meow-whiteboard.jpg]].
### Results
I have started a .[[ResultsPage]] to preserve some of our images for posterity. Please feel free to edit it and add your own (either as attachments, or links to files on lofar9).
### Social Program
Tuesday 30/01: Workshop dinner in Dwingeloo
Wednesdays 31/01, 07/02: Bridge & misc, 20:00 at Jan's place in Pesse. Featuring other games for the non-bridgers, followed by cross-cultural alcohol sampling and profound conversation.
Fridays 02/02, 09/02: Indoor football -- everybody is welcome to join, our skill level is all over the place anyway. Please bring a pair of indoor sports shoes (i.e. non-marking soles).
### System Requirements
You need a laptop with ssh and X11, so you can log into our machines and run X applications remotely. Usernames, pairings and machine assignments for the first two days are as follows:
* birch: boomsma/oosterlo kemper/butcher rnijboer/hamaker bemmel/jmiller
* lofar9: omar/strom brentjens/vogt
* lofar10: bernardi/pandey panos/thomas
* cedar: vjelic/mohan kieviet/usov ger/saleem
* jop01 (10.87.10.1): reynolds/sundaram
* jop03 (10.87.10.3): loose/zwieten
After the first two days some people are leaving, so we'll re-assign some people around.
Please check connectivity, all accounts are currently ready, except jop01 and jop03.
* {{{$ slogin -Y yourhost.astron.nl
... $ xclock # just to test X $ cd Workshop2007
$ svn up $ cd Intro1 $ meqbrowser.py # you should see the [[MeqTree|MeqTree]] browser pop up }}}
* NB: If you already had an account before, you should know your password. Otherwise, call me on 0521 595 167 (office), or 050 528 0050 (home) and I'll give you one. **Please change your password to something you will remember. Do this both on the machine you have been assigned to, and on lofar9.**
### X11 Issues (and Macs)
This tip applies especially to people with Macs, but Linux notebook users may find it useful too, since it makes the X display quite a bit faster.
There's some weird interaction on the Mac between ssh and the X server. I recommend doing as follows (for 'birch', substitute your assigned host from the list above), although this will only work at ASTRON, and not outside the firewall.
* ```
$ xhost birch # this is still on your laptop
$ ssh birch
...
birch:~$ export DISPLAY=${SSH_CLIENT%% *}:0.0
This makes apps on birch talk directly to your X11 server, rather than going through ssh. You can put the command into your .bashrc if you like.
