Good bye bzr, welcome git

I like version control systems and have been using them for a long time. I've spent much time in CVS and even used RCS to quickly bring directories under version control. I've also performed duties as a version control and release manager using CVS. That time has exposed me to many pain points with CVS (directories are not versioned, you can't rename files without tricky stuff, merges arrive on the "pain train", etc) and so I was looking for something new and better for my personal projects.

logstash and kibana for adhoc log analysis

logstash and kibana for adhoc log analysis

In the past I've pulled various logs into elasticsearch for some quick searching through large logs and to get a clean timeline across multiple servers. I had planned on building this into a tool for more general consumption.

As it turns out there are already some tools out there that let me do this pretty easily: logstash and kibana.

Ubuntu 12.10 and s/pdif or iec958 or optical audio output

I've given up on cable and satellite TV. For my needs a combination of MythTV, Hulu, and [Amazon Prime] are sufficient.

So, essentially my "TV" is an Ubuntu box. Recently that box died and I replaced it with a new one that featured an optical audio output or TOSLINK or S/PDIF.

Everything basically worked ... except 5.1 surround sound to work. All I kept getting was stereo.

Getting it to work as 5.1 surround was not too actually hard, once I pieced all the details together.

Here is the step by step.

adjusting video settings for a google hangout in Ubuntu

At work we often conduct meetings as a Google Hangout and Ubuntu running Chrome works very well for this. Unfortunately, I found that sometimes the video quality was a bit iffy and the controls offered by Hangout don't let you adjust those in Ubuntu.

So, how can you adjust the video settings? Well, guvcview can be used to adjust the settings before joining a hangout.

faster keyboard link navigation in chrome

I'm pretty happy with chrome. mostly for speed and the sweet incognito mode that lets me test with a clean environment quickly. It's been a long time since I switched from firefox, but there is still one thing I was missing: fast link navigation via the keyboard.

In Firefox, you can it the single quote and it starts searching for links with text being entered (The backslash does it for all text).

space: the final fronier .... in bash

Space: the final frontier. These are the voyages of intrepid bash scripter. His multi-hour mission: to explore strange new whitespace, to seek out new ways of escaping, to boldly go quote what no man has needed to quote before.

Last night I was confronted with something I don't generally relish: a bug in my code.

In this case the script essentially was intended to trigger some file copies based on the input in a web form.

Basically, the user plugs in some variables, including a path for the original files and submits.

goodbye screen, hello tmux

I've been a screen user for longer than I seem to remember. To me it's very powerful to leave my session running (often with long running commands) and being able to just hop right back in and continue where I left off. Screen has been awesome for me, but there have been some things that just annoy me. My biggest gripe is the naming of the tabs. I've tried a bout a dozen different things to set the titles automatically, such as when I SSH from the screen session to another host (I do that *LOT*).
