install pygit2 + libgit2 w/ SSH support on ubuntu

I wanted to use Saltstack‘s gitfs to easily reference salt formulas from my gitolite repository over ssh using key-based authentication. In order for salt-master to do this, you need pygit2, which needs libgit2, which isn’t yet packaged by ubuntu. You can download a libgit2 deb file, but that doesn’t have libgit2 compiled with SSH support, […]

writing saltstack formulas

SaltStack is a great open-source, cross-platform automation system. It lets you configure servers using declarative yaml files and python. You can create custom “states” during yaml/python, and then say “make server X have state Y”. There’s a lot of plumbing involved which I’m not going to delve into, but it’s pretty neat stuff and doesn’t […]

working with R, postgresql + SSL, and MSSQL

I’ve been able to take a break from my regularly scheduled duties and spend some time working with R.  This is a short log of what I did to get it working. The main things I’m looking to do is regression modelling from a large dataset I have in postgresql and various stats calculations on […]

git-like line counts in svn using bash

I really like how git tells me how many lines inserted/removed when I commit, and wanted to get something similar from Subversion.  I’m working on a refactoring of an older system, and I wanted to know how my refactorings were effecting the code.  I think I’m going to remove a lot more code than I […]

the beginnings of bar charts

Spent a ton of time today playing with adw-charting. I wanted to expand on the source contributor graphs from the other day, and ended up implementing some basic bar chart functionality. I’ve read a lot of complaints about the lack of lisp libraries, so whenever I sit down to do some random task, I try […]

more adw-charting paperwork complete

Made another release tonight, but there are no new features, this is just tying up some loose ends: added a LICENSE file and license headers in each file. removed cl-vector-chart.lisp, which I had looked at for inspiration, but ultimately decided not to use. added a lisp file and shell script to automate making a release. […]

adw-charting is available for download

Someone on #lisp started talking about making line charts using vecto, so I went ahead and got setup a project: Now I’m somewhat flooded with digital paperwork: Get my darcs repository onto Update the documentation to point to (removed all the damn lies, so only vague untruths remain) Get access to […]

Quicken 2007 fails

I use quicken to manage my finances, and find it overall does an excellent job, but every now and then it does something outrageous: Seriously?   You still can’t handle that?  I guess that means its time to take another stab at gnucash.

Setting up a computer for Flash development

There are several tutorials out there on how to do this, but they all differed a little, and figured I might as well note mine.  I’m replicating the setup I have at work onto a home computer, so this is my second time around. Download and install Eclipse, the java version should be just fine […]

Graphing my fuel efficiency with lisp and Vecto

Gonna try to be quick about this, as there’s chicken on the grill. I took a break from Team Fortress 2 to play some more with Vecto, another fine library from Xach. I started another post about last weekend’s lisp playing, but this one got finished first. I’ve been tracking my fuel efficiency for a […]
