Post Formatting

If you looked at my latest web log post, you noticed the formatting of code was broken. In previous posts, it has also been less than ideal but for different reasons that no longer apply. I traced ... Continue

Web Log Posts

Hey guys, I'm the only one who's posted any web log posts. Won't somebody chip in so it doesn't look like it's all about me? Maybe I should impersonate Alvah and copy and paste his book reviews fro... Continue

Profile

Location (Town):: Bangor

About Me:: I've been a Melug North member since late 2001 and accepted leadership after Jeremy Radlow moved away in 2002.

I started using Linux in September, 1998 with RedHat 5.1. In 2001 I started the LFS FAQ which I maintained for a couple years. Currently I maintain the iana-etc project which I first released in 2004. At home, I use Gentoo although I hope to return to scratch building when I get that copious free time I joke about.

I currently get my money in retail (hardware), but as of May 10, 2008 I would like to find something else quite quickly. If you're interested in hiring me, now is the time. In my spare time, I write various tools for myself, mostly in the shell, and try to sate my addiction to learning new things.

Efficient Backups Using rsync And An External Disk

I was fixing my backups the other day, went looking, and discovered rsync --link-dest. With it, rsync substitutes hard links for files that haven't changed. The result:

1200x900

For some time I've been running my monitors at 1152x864. I picked it because it was a standard resolution (although uncommon) and the next one down from 1280x960 which was slightly too fuzzy. Unfortunately, it leaves me about ten characters short of three xterms across each monitor. Today I switched to 1200x900. That three xterms across has made my world a much happier place, and you know, anything that cares about resolution is going to want 1024 or 1280 anyway.

XmlStarlet: XML from the Shell

While the religious fervor surrounding XML is dying and JSON is saving us from some of the more painful uses of XML, if you use the shell much, sooner or later you'll want to quickly scrape something out of a web page or other XML like document.

XSLT has a good set of functionality for this but its smallest size is a file and that's five lines long. For the shell, the smallest size must be a couple short paramete… Continue

How to Generate a Summary of Gnuplot's Palette Formulae

Sometime late this morning I decided to fix a small visual artifact in a 3D plot produced by Gnuplot. That was a mistake.

After spending something like nine hours wandering around the web, poking through Gnuplot's horrible help interface at its built in documentation, rethinking my problem, rethinking my data, rethinking my goals, trying something, building a test case and trying again, and repeating the process, I am back to where I started plus o… Continue

Wide Finder I

This is the first in my series of posts on Tim Bray's Wide Finder meme. It covers solving the basic problem with classic Unix shell code. Future posts should cover the "wide" part, parallelizing the problem arbitrarily.

A bit of background: As Moore's Law slips and the internet's growth does not, more and more people are interested in problems bigger than any one processor or machine can handle. So everyone had… Continue
