Uptime Records

This makes me happy – to have 99% uptime over 3 years or so.
It also makes me sad – to have missed out beating my previous record.

Omicron Upgrade

Over the past few months I’ve been noticing that my virtual server (omicron) has been frequently using over 80% of it’s available memory. This is likely due to the fact I started hosting a ruby on rails application (redmine) which means another set of processes (mongrel cluster) running the whole time in addition to what’s already there.

File Synchronisation With Unison

Unison is an application which allows files to be synchronised between local or remote directories. I find it incredibly useful for keeping my documents etc synchronised between my various computers. I use it for many things, including my ~70GB music collection so I can verify that it can handle large(ish) amounts of data.

Unison is cross platform (Windows, Mac, Linux) which is nice bonus, if not actually that useful for me at the moment since I run all Linux.

By way of example, I’ll explain how I sync my music collection between my desktop and laptop. The exactly instructions are based on Ubuntu, but the overall process is much the same whatever you’re running.

Site Updates

Over the weekend I’ve had a bit of a reorganisation on charcourt.com. I’ve split this blog off onto a separate subdomain (blog.charcourt.com) and redone the main site using DokuWiki (www.charcourt.com).

The migration went pretty smoothly, with only some bits of content left to move.
