Roof colours impact on temperature

These are some preliminary results for roof colour tests I am conducting. The setup is 8 equal sized pieces of roofing material, some painted with different coloured roof paints. They were left out in full 12noon summer sun (Lat 19 south), and the temperature of the under side of the material was measured after 30 minutes exposure. Results follow:

1. White Colour Bond 48C
2. Painted white Zincalume 45C
3. 2 coats painted white Zincalume 43C
4. 2 coats painted white Colour Bond 45C
5. Black painted Zincalume 70C
6. Silver painted Zincalume 63C
7. Gold painted Zincalume 60C
8. Unpainted Zincalume 50C

I’m going to conduct this again soon, with an 8 channel data logger, so more precise results can be presented. But for now, you can get the jist of what is happening.

Migrating Drupal using phpmyadmin and CLI

I recently had to migrate a Drupal site from a CPanel site, to a host where I had SSH access. The only logical way I could extract the database was using phpmyadmin’s export function. Then I had to import it at the new host using cat … | mysql. However, even though the fields aren’t unicode, they contained unicode chars. This caused a real headache when I did the import, as there were garbage chars in the resulting table.

This is a similar/same problem.

In the end, I found if you define a default character set then all things fall into place.

cat localhost.sql | mysql -uUSER -h mysql.HOST -p --default-character-set=utf8

Just a note for the files really.

Purging BSPlayer

A year or so ago I found this neat little video player for Windows [sic] called BSPlayer. Recently it started playing up, so I went looking for an updates, and installed BSPlayer 3. Along with this version comes a little piece of adware called SaveU. Thinking I could deal with a few popups to support this app I went ahead with the install. Instantly the speed and stability of my PC was trashed.

Then, when I went to uninstall the software the uninstalled would freeze the computer. Searching the forums, several other people were having the same issue.

In the end, starting winxp into safe mode and uninstalling BSPlayer, then SaveU was the only technique which would work for me.
