My personal little “cloud” May 24, 2011

Here it is, and it works perfect:

  • You will need a VPS or a home server. I’m using the wonderful, fan-less Shuttle XS35GT with a small SSD, as it is also my HTPC
  • A Linux distribution. I very highly recommend Mint 10 if you’re using the XS35GT so that you get a working audio + wireless and a stable XBMC, otherwise you may wish to use an LTS release like Ubuntu 10.04 or Mint 9.
  • An installation of eGroupware, to use its addressbook and calendar modules with its GroupDAV and SyncML synchronization facilities. You can easily install eGroupware using the deb repository provided on the project’s site.
  • Thunderbird, Lightning and the SOGo connector to support GroupDAV. Make sure you don’t use the “SOGo Lightning” extension; at least for me it didn’t work. Then subscribe Lightning to the eGroupware calendar and addressbook. Don’t bother with TODO items, unless a flat list is your thing.
  • A SyncML application to synchronize your phones. My Nokia E71 comes installed with one, while on an Android you can use the wonderful Synthesis client. Synthesis offers clients for additional platforms, but I only tried the one for Android.
  • The amazing Tracks application for GTD. It takes some effort to install, but it is totally worth it. You can also subscribe Lightning to various views of Tracks exported calendars. I’ve subscribed only to the one for due items, so that they appear with deadlines in my calendar. There are also two mobile applications to sync with Tracks, one for the iOS and one for the Android. Unfortunately the latter doesn’t work yet with Tracks 2.0, but it looks like it’s only a matter of time before it does.
  • …and, finally, Mindtouch Core (DekiWiki) as my data sink. There’s also a for-pay version, but I’m using the free/open-source one, which is fine. It’s also installed via a deb repository. I guess others may prefer some other platform, but for me Deki is perfect.

Then, your router set to post its address to DynDNS/No-IP or a similar service, and some CNAMEs in your domain to point to the hostname you have chosen (or simply the address of your VPS). All three services (Mindtouch, Tracks, eGroupware) are powered by Apache2, on virtual servers over HTTPS.

The data is yours!

PS: Special thanks to Yannis for suggesting to use eGroupware instead of SOGo+Funambol. A great improvement, indeed.
PPS: I only accept IaaS to fall under the term “cloud computing”, hence the quotes in the title.

Suspending a Dell 6410 w/ Mint 11RC May 20, 2011

If you just installed Linux Mind 11 RC on a Dell Latitude 6410 and, while on wireless, your system crashes when trying to suspend it, try this:

sudo mkdir /var/run/wpa_supplicant

This should fix it.
