git_get

Just a quick share for today. I just finished up a little perl script that you can run on your git repositories. It produces a bunch of statistics about the repositories. You can see it over on git hub.

A Brief Introduction to the IETF’s BIER (Bit Indexed Explicit Replication) BOF

In November I participated in the IETF meeting in Honolulu Hawaii. There are many reasons to attend the IETF but on a personal level I love going to the meetings because of the learning experience they provide. There are the working groups I always attend based on my areas of expertise: IDR (BGP), OSPF, PIM,

Regular Expressions

I’m by no way a regex expert but if you’re a software engineer that doesn’t know about regular expressions that should definitely be your next skill to add. A great website to start with is regular expression info. For those of you that know all about regular expressions I just wanted to share a nice

Twitter and menv update

I’ve been a little slow on updating this site but with good reason. I recently was hired by Vyatta (a Brocade company) and I am very excited about the team there. Just as always let me say the postings on this site are my own and don’t necessarily represent Brocade’s positions, strategies or opinions. In

Raspberry PI Colocation

If you are a hardware or software person its great to play around with some of the various single board computers there are. In particular the Raspberry PI has a low price point which makes it perfect for little side projects or even bigger projects where for instance you want to test some distributed computing
