htaccess Subdomain Redirection

Posted on August 8, 2008, 8:41 am

My blog is set up as a subdomain to my main site so http://bobpeers.com/blog/ should really serve the content from http://blog.bobpeers.com. Just recently I noticed that link pointing to my blog directories but accessed through the main site were not returning 404 pages for missing pages. For example a link pointing to http://bobpeers.co [...]

Encryption Using Gnome Seahorse

Posted on August 6, 2008, 9:42 pm

After my previous post about GNU Privacy Assistant and not having an easy encryption option built into Nautilus it seems that i didn't look very far. Today I researched a bit deeper and installed Gnome Seahorse. Essentially this does exactly what I was looking for. It allows cre [...]

GNU Privacy Assistant

Posted on August 5, 2008, 10:24 pm

I decided to give GPA a try just to see how easy it is to encrypt files on Linux. The program installed no problem using yum. # yum install gpa Upon starting I created a key (when the warning says this takes a while it's no lie, it took about 5 minutes on my computer but I've since [...]

Arbitrary Ordering Files

Posted on August 5, 2008, 9:27 pm

This isn't something I would normally think about since I know you can only sort folders by name, date or any other property available. However a friend had a problem with her computer and asked me to take a look. The problem was that she wanted to reorganise a folder of holiday photos in an arbitrary order chosen by her, basically drag and drop [...]

Fedora 9 No Sound on Flash Videos

Posted on August 2, 2008, 9:44 pm

After living with no sound on flash videos since I installed Fedora 9 ( I don't watch many videos as you may have guessed :-) ) I decided to look for a fix tonight. It turned out to be much simpler than I imagined, I should have done it ages ago! For reference I had all other system sounds but the controls on the playback page of the Pul [...]

Create a File of Given Size

Posted on July 31, 2008, 3:27 pm

Sometimes it's useful to be able to create a file of a specific size for testing purposes, for example to test network bandwidth by copying a large file of known size. It easy to do on both Linux and Windows. First on Linux: dd if=/dev/zero of=file.img bs=1k count=10000 This creates a 10MB file called file.img, bs is [...]

No More New Fonts May Be Applied In This Workbook

Posted on July 31, 2008, 11:55 am

I came across this very strange error message in Microsoft Excel today. The user has a workbook with 114 charts and he seemed to be hitting some hard limit in Excel. It turns out that if you create a chart with it's font set to 'Auto scale' then instead of using one font it uses 2 ore more and there is a limit of 512 fonts per workbook. [...]

The title says it all. This page describes how to do it and to stop the wp_posts table filling up with multiple copies of the same post. [...]

Public Domain File Icons

Posted on July 25, 2008, 9:41 am

I was looking for some small file icons to use in a web page on a company Intranet site. I found some icons at splitbrain.com that are in the public domain and so are free to use/modify/do whatever you feel like for personal or commercial use. [...]

My Computer is the New Bottleneck

Posted on July 25, 2008, 9:28 am

I decided to download and install Ubuntu 8.04 into a Virtualbox virtual machine last night and something funny occurred to me for the first time. In the past with slow internet connections it would take many hours to download a 694 MB iso file (even at 2Mbps it would take 46 minutes) [...]
