Open New Terminal Tip

By On December 5, 2011 · Leave a Comment

I tend to open up several terminals when working on a project, so I usually want them to start in the same directory I’ve been working with. Stick this in your ~/.bash_profile to have your new terminal windows automatically cd to the directory you last used.

export PROMPT_COMMAND=’echo `pwd` > ~/.lastpwd’
cd `cat ~/.lastpwd [...]

Multiple Filetypes in Vim

By On April 27, 2011 · Leave a Comment

I’m finding this useful as I work with snipmate and have defined custom snippets for solr config files. I still want to use the XML filetype, but I have no real use for the solr fields outside of editing the schema.xml file.

set filetype=xml.solr

Excellent question on superuser.com with a fantastic answer. If anyone needs to jump through multiple servers via ssh (or any other protocol) take a look at this answer.

Using iWatch to Automatically Run Unit Tests (Linux)

By On February 23, 2011 · Leave a Comment

iWatch is a perl script that uses inotify to monitor files directories. It’s similar to the watch tool, which can do all sorts of stuff if the files or directories it’s watching are modified or affected in pretty much any way at all.

Install iWatch

apt-get install iwatch

I’ve got this 1 liner in a [...]

This was really useful for me in scripting TextEdit to run my unit tests, as Erlide has been crashing every time I use it.

To get a quick idea of what ports you have open on your local box, you can use nmap.

MacBook Air Battery Drain While Sleeping

By On December 11, 2009 · Leave a Comment

I bought a MacBook Air in June this year, refurbished. I didn’t really use it a lot for day to day work, and when I didn’t use it I was charging it. It was very convenient – it weighs practically nothing and has almost no impact on me while traveling. When I cut back on [...]

Peeping into memcached.

Really interesting read about how to examine what’s stored in memcached.

Peep uses ptrace to freeze a running memcached server, dump the internal key metadata, and return the server to a running state. If you have a good host ejection mechanism in your client, such as in the Twitter libmemcached [...]

Compiling libjpeg on 64 bit Centos

By On July 7, 2008 · Leave a Comment

I ran into an issue just now compiling libjpeg on 64 bit CentOS. I found this very helpful post that gives a workaround using a config.guess file from libtool. For some reason, I didn’t have the folder he suggested, but I did have the alternative (automake).

cp /usr/share/automake-1.9/config.guess .
cp /usr/share/automake-1.9/config.sub .
