Alpine

To access a Google Mail account with IMAP:

personal-name=<YOUR NAME>
user-domain=gmail.com
smtp-server=smtp.gmail.com/submit/user=<YOUR GOOGLE USERNAME>@gmail.com/novalidate-cert
inbox-path={imap.gmail.com/user=<YOUR GOOGLE USERNAME>@gmail.com/ssl/novalidate-cert}Inbox

All other entries can left by default. However, it may be interesting to set a few other fields such as:

customized-hdrs= From:
alt-addresses=myemail1@blah.com, myemail2@blah.com
copy-to-address-to-from-if-it-is-us

display-character-set=ISO-8859-15

alpine -d tcp,imap=4

Amarok

• install amarok
• connect the mobile phone using WMStorage: the devices is mounted as a USB device (for e.g in /media/disk)
• in amarok, configure it as a generic audio device. Connect it.

CUPS

CUPS is meant to help Unix users to print. But honestly, I'm probably dumb, because I've always encountered problems printing from Unix machines :( Anyway, this is how far I've been.

pfexec pkgutil -y -i cups

CUPS is typically managed by the web, on port 631. Try 127.0.0.1:631

Davical

$ sudo apt-get install postgresql davical php5-curl

pg_dump -h localhost -U postgres -Fc davical | gzip > davical-$(date +%Y-%m-%d).pgdump.gz

1. Install postgresql, davical, apache
2. Install davical as in here until you are able to log on the web site https://.../davical
3. Create 2 "principals" - those are the users/calendars. Set passwords
4. Set RW rights for one's own calendar and R for the other calendar
5. Restore the database from an empty one:
   • log as postgres and drop the database:

     # su - postgres
     postgres@legumic:~$ dropdb davical
     

   • create the database:

     createdb --owner davical_dba --encoding UTF8 --template template0 davical
     

   • restore the database:

     sudo pg_restore -Fc -h localhost -U postgres -d davical davical-Saturday.pgdump
     Password:
