Lassen Volcanic National Park

We spent the Memorial day weekend hiking at Lassen National Park.

The drive was pleasant and surprisingly no traffic on the way and back. The weather was great and we did 2 hikes - Cinder Cone and a hike to Devil's Kitchen and Boiling lake in Drakesbad.
Unfortunately one of the main attractions at the park (Bumpass Hell - heh real name) was not open for the year yet.

A simple guide to using Unix/GNU Linux command line tools for fiddling with log files (*runs on Windows too)

I've been meaning to write this post for years now. Every time I thought about compiling a basic list, I've told my self "Nah.. there must be tons of examples on the net". Yes there are tons of them but I couldn't find anything:

• That helped absolute noobs with a consolidated list
• That demonstrated actual fiddling with Java log files
• Something that works on Windows(!) No, I don't mean the awful Cygwin tool but something like Busybox or the wonderful Gow

So, here it is:
Enjoy!
