Take one 3U server from SuperMicro, fitted with an Adaptec 31605 SATA RAID controller and 16 one-terabyte disks. Create a RAID 0+1 array for data storage, with 14 of these 16 disks. You get:

#available storage
[root@sam119 ~]# df -h /data
Filesystem Size Used Avail Use% Mounted on
/dev/sdb1 6.3T 941M 6.0T 1% /data

#write test
[root@sam119 ~]# dd if=/dev/zero of=/data/toto.txt bs=4096 count=2621440
2621440+0 records in
2621440+0 records out
10737418240 bytes (11 GB) copied, 38.8372 seconds, 276 MB/s

#read test
[root@sam119 ~]# dd if=/data/toto.txt of=/dev/null
20971520+0 records in
20971520+0 records out

When porting an SDL game or application to Maemo, if you wonder why the app doesn’t show up in the Task Navigator (at the bottom left-hand corner of the screen), you need to do two things. Example with Biloba:
Match the SDL window’s WM_CLASS and the .desktop StartupWMClass, the easiest being:

• biloba.desktop:

Exec=/usr/bin/biloba.sh
StartupWMClass=biloba

• /usr/bin/biloba.sh:

#!/bin/sh
export SDL_VIDEO_X11_WMCLASS=biloba
/usr/bin/biloba

Then, the window will probably appear as unnamed in the task list if the application is full-screen, in which case forcing the WM_NAME helps.

Biloba is a little board game that I wrote a while ago for Guillaume Demougeot, its inventor. It’s free software, thanks to Guillaume’s willingness, and as such I’m glad to work on it from time to time…

I just finished the porting of that game to Nokia’s Internet Tablets (770, n800, n810). Get it here while it’s fresh!
