Pondering version two of "sel"

Posted 04-01-2015 at 03:15 PM by ttk (Unpopular Positions: One Geek's Take)

Some years ago, I wrote a little utility called "sel", short for "select" (to avoid confusion with bash's "select" builtin).

It's more or less SQL's "select" statement for the command line, reading structured data on stdin and writing structured data on stdout, optionally filtering rows (like a structured-data-savvy grep) and creating / removing / reordering columns and changing the format. For instance, it could read CSV in and write tab-delimited...

Itching to write a new GPC article

Posted 01-31-2015 at 04:41 PM by ttk (Unpopular Positions: One Geek's Take)

It's been more than two years since I wrote something about the General Purpose Cartridge for military rifles http://ciar.org/ttk/mbt/guns/gpc.2012-10-23.html

I wanted to hold off so I could improve my ballistic analysis software, collect more empirical evidence, and learn something about the GPC candidates and legacy cartridge upgrades under development by various military institutions, but these developments have been slow in the coming.

When I've had time to spare...

Cat Silliness

Posted 08-02-2014 at 01:17 PM by ttk (Unpopular Positions: One Geek's Take)

Who'd have thunk it? Simon, our laid-back happy-go-lucky orange kitty, is a scrapper!

Since we moved to this property in 2008, our cats have been hemmed in by the territories of cats from the surrounding neighborhood. If they ventured too far from the house, sometimes while still on the property, they'd get their asses kicked.

Sam, our big grey tomcat, held the other cats' territories out on the periphery for a couple of years, but he'd come out on the losing end of...

Time::TAI::Simple

Posted 07-30-2014 at 10:09 PM by ttk (Unpopular Positions: One Geek's Take)

Two things: First, my wife tells me this blog's interface sucks, and she hates trying to read it. Apparently it's horrible for users who do not have an LQ account. I'm kicking the tires on some alternatives.

Second, I've uploaded Time::TAI::Simple to CPAN. It provides a high-resolution count of seconds elapsed since the beginning of the epoch, much like Time::HiRes, but un-"corrects" for the IETF's leapsecond adjustments.

This means:

Datashack Stirrings

Posted 07-20-2014 at 08:54 AM by ttk (Unpopular Positions: One Geek's Take)

One of my ongoing projects, for the purpose of facilitating other projects, is the conversion of our wellhouse to a "datashack" and light workshop. The goal is to run various computers in it without introducing undue noise or heat to the main house.

It's been a while in the coming, but it's coming. Yesterday marked two big steps: I moved my computer cabinet from the garage (where I basically never got to run the systems mounted in it) to the wellhouse, and I installed...
