  1. Install ntpsec on FreeBSD

    A short article on how to install ntpsec on FreeBSD. Tested with 0.9.7 and 1.0.0.

    Note

    There is/was a bug in the ntpdate implementation that set the clock to a completely bogus value. So I’ve since written a simple script that runs from cron to fetch the time from a near NTP server.

  2. Database scheme for resin recipes

    This document explores how an SQLite database could be used to store data for the resin-calculator. Normally, the recipes are a dictionary keyed to the name of the resin. The value of each recipe is a list of (component, parts-by-weight) tuples. Since a database only contains tables, where each row has the same form, how do we store such infomation in a database?

  3. Converting RCS history to git

    Before the rise of git, I used rcs as my version control system. Because I want to standardize on git, I am slowly converting old repositories.

    In this article, as an example, I’ll be converting my old perl scripts in ~/src/perl.
