I use my XO to test and debug my projects for a few reasons, (1) XO processor speed is a limiting factor while working on Physics, (2) I set up a good development environment using FusionFS, and (3) I never got around to compiling/SWIG wrapping Box2D and figuring out the Elements build process on my Mac.
Shell commands I've used to make testing/debugging on the XO possible/more tolerable:
sudo yum install git sudo yum install emacs # Though vi and nano are included in builds, I learned emacs in COMP211 at Wesleyan sudo yum install lsof # Used to slim down Elements into Physics sudo yum install screen # used for mirroring ssh on your computer and the XO strace date # Learn to watch programs work! sugar-control-panel -s radio off # Airplane mode... thanks Henry! grep -v # Inverse grep (don't show these lines) strace -eopen # (or e trace=open, trace only system open call) sudo dhclient eth1 # DHCP work it find -name "*.pyc" -delete # Delete all pyc files chmod 0600 ~/.ssh/id_rsa # Proper permissions, 0667 or 0660 no worky ctrl+r then a number: BASH history depmod after reboot... then reboot
Restarting Sugar/X: ctrl + alt + erase
Screen
Developing ON the XO with screen..
- Set up User:Bjordan/SSH
- ON THE XO:
sudo yum install screen
- ON THE XO:
screen
- ON YOUR DESKTOP (having SSH'd in)
screen -x
. Your screens will be synced up. COOL! It's like a ghostwriter is on your XO! - Run your activity by
sugar-launch activityname
. activityname is the name you put in activity/activity.info - Bonus round: open up another SSH session for User:Bjordan/vim-ing out
