GAE domains

How to register a domain with godaddy and enable free hosting on Google:

• Purchase domain from godaddy
• This will use the default godaddy nameservers (ns35.domaincontrol.com, ns36.domaincontrol.com, etc)
• Set up Google Apps for domain
• Complete signup form and request cname value to verify domain
• Login to godaddy domain manager (advanced)
• Add www forwarding to get naked domain to work (use masking)
• Delete all the default cname values, which point to various services
• Add google.com cname value and use default TTL
• Add cname ghs.google.com with alias www
• Add www sub domain through GAE dashboard
• To enable email use this service
• Had to wait 10 minutes before service was active

SSH timeouts

Add this to ~/.ssh/config to avoid ssh timeouts (create file if does not exist):

Host *
    ServerAliveInterval 240

Call url with CRON

Call URL periodically with CRON, discard HTML, and send all output (including errors) to file:

$ crontab -e
0 * * * * wget URL -O /dev/null 2>> ~/cron.log

Memcached on webfaction

Choose memcached from custom install scripts and set extra info to maximum number of MB (eg 2)

This executes:

memcached start -d -l 127.0.0.1 -m 5 -P $PWD/memcached.pid -p XXXXX

Then can access with gluon.contrib.memcache

Take note of port used

Komodo

Run current file with Python: %(python) "%F"

verbose = True

merge = internal:merge

screen

Use ssh to login to server and start screen:

ssh -t $1 'screen -dRR'

screen -S main = create new screen session named "main"
^a d # log out of screen, but leave running
