Finally Published Physics::Ballistics to CPAN!

Posted 07-09-2017 at 05:57 PM by ttk (Unpopular Positions: One Geek's Take)

Around 2007'ish I started collecting/writing formulae related to the physics of ballistics, but they were a disorganized mish-mash. In 2014 I decided to straighten them out, write unit tests and documentation, and publish them to the CPAN central code repository.

This weekend I finally got it submitted!

I feel like it should be a huge milestone, but it gives me...

Another systemd zero-day security vuln

Posted 07-06-2017 at 11:26 AM by ttk (Unpopular Positions: One Geek's Take)

Systemd falls back to root privileges when an invalid user account is specified.

Shadow-tools allows the creation of invalid user accounts.

Face, meet palm.

The systemd devs aren't being gracious about it, either.

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...
