New Blog -- Entropy Pump

Posted 06-25-2017 at 03:19 PM by ttk (Unpopular Positions: One Geek's Take)

I've started a new blog, Entropy Pump, hosted on my own colo server.

I'm not sure yet what the division of labor is going to be between Entropy Pump and this LinuxQuestions blog. The current notion is to make the LQ blog mostly about software (and Linux in particular) and Entropy Pump about everything else.

If that pans out, I will update the description of the LQ blog accordingly.

Automating custom Slackware install tarball and post-setup tweaks

Posted 07-31-2015 at 10:47 AM by ttk (Unpopular Positions: One Geek's Take)

The other day I thought, not for the first time, that it was kind of dumb to be manually building my stripped-down Slackware install tarball, and having to remember the tweaks I like having done to the system after "setup" but before the first system boot. I end up forgetting things, getting frustrated at the minimalist busybox-based setup environment, and going back and making some changes after first boot instead of before (and as often as not sneakernetting files to the new system...

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...

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:
