Getting Started with H2

12 Nov 2019
I will walk through the basics of creating a new H2 database on a Windows machine - the commands for Linux are pretty much the same (it’s all Java-based). I will take a close look at H2’s connection URL syntax, as it was somewhat confusing to me, the first time I tried to use it.

A walk-through of how to use IMDB’s publicly available movie data to set up my own database of realistic - and also reasonably large - data. I use this in various other projects, demos and investigations.

PuTTY using Solarized Light

14 Sep 2018

Solarized Light is much nicer for me to use than the default PuTTY color scheme.

Combined with a couple of other changes, it gives me a nice layout in PuTTY.

PuTTY stores its settings in the Windows Registry.  So, to apply Solarized Light to a session:

  1. Back up your registry settings using Regedit’s export utility.
  2. Create a PuTTY session in the usual way, and save it.
  3. Place the below in a text file with a .reg file extension.
  4. Replace FOO%20BAR on line 3 with the PuTTY session name (spaces are %20).
  5. Double-click the .reg file to launch the Registry Editor, which loads the values.
