Changes to GU visual identity Powerpoint templates

The latest versions of the Uni Powerpoint templates have slightly different RGB colours from the original guidelines. Looks like a improvement snuck in without telling anyone.

Colour R G B
Old blue 0 53 95
New blue 0 33 60
Old SciEng 119 120 0
New SciEng 91 101 27

For the new SciEng template the logo remains the same. For the generic Uni template the logo has been altered so the shield is the same shade as the new blue. I’ve approximately replicated this in Powerpoint 10 by altering the logo image with Brightness: -12% and Contrast: 25%. It’s not a perfect match for the other colours (comparing them to the logo that comes with the template), so I suspect there’s probably been some gamma tweaking or similar going on.

My version of the College pptx template with the school logo school_general.pptx. Has the Tower background as a title slide option. It has to be said, the green does look a little less yucky than before. Now if only they’d apply this to the website as well…

Replacing heatsink on Dell Precision T1500

This should be a five-minute job, and if Dell used the standard mountings it would be. Guess what…

The T1500 has the mounting holes in the standard places for a LGA 1156 socket, but has screw bosses in these holes, presumably held there by a backing plate behind the motherboard. The stock heatsink screws into these with captive screws – springs hold the bracket down. In theory if the bosses were removed a standard heatsink would clip in, but this would require the motherboard to be removed. Alternatively, the screws with the ~2mm stand-off bits (from the old-style green plastic CD drive mounting rails with the anti-vibration mounts) fit and work quite well. Note the stand-off in these is not quite right, so you probably don’t want to tighten them fully – just enough to hold the heatsink down firmly (It’s best to lay the system down so that the heatsink can rest on the processor to fine-tune the position).

Akasa AK-CCE-7101CP in Dell Precision T1500

(Why not just replace the fan? Because although it’s a standard size (80x80x25mm) it’s a high airflow model. RS and CPC don’t have anything similar with a 4-pin plug. And as a new heatsink and fan could be got for less than a tenner (before shipping charges) from Misco…)

Getting WebCal to work with DAViCal

Well, that was odd. Managed to get WebCal to work (after realising it doesn’t hook into the DAViCal database at all – it’s a completely separate admin account, user accounts etc). After creating user, couldn’t add calendars to them. Eventually tracked it down to utils/helper.php and the encode and decode functions which were retrieving $iv of the wrong lengths – saw 21 and 24 bytes. After putting code in to watch the variables created a new user – which worked perfectly. Disabled debugging code, deleted all users and recreated Glasgow10m user – works fine. Bizarre.

Installing Bedework

Install Java

Needs to be the Oracle JDK. Download the .bin file and make it executable. Create appropriate directory, change to it and run the .bin file.

update-alternatives --install "/usr/bin/java" java" "/usr/lib/jvm/jdk1.6.0_31/bin/java" 1

Creates link for java in /usr/bin/

update-alternatives --set java "/usr/local/bin/oracle-java-default/bin/java"

Not needed for a clean install – there are no other versions of java on the system.

Then in /etc/environment

JAVA_HOME="/usr/lib/jvm/jdk1.6.0_31"

Gave up at this point and decided to give DAViCal another go.

DokuWiki data migration

Migrating files in media directory under data works fine. Suspect copying over the pages directory into the new namespace would have worked ok as well, if namespace is flat and links are relative. For hierarchical structures there will be a lot of link editing to do, but that’s almost always the case anyway. And you need to browse all the pages to get them indexed anyway.
