What I learnt from my first DeFi experience
There’s a Bitcoin enthusiast called Michael Saylor that seems to do a hundred interviews a day lately. “Enthusiast” is too weak a word for him. He’s our champion. He has laser beam eyes of pure Bitcoin energy. From listening to him I have understood that not only has he put all his spare cash into […]
Fixing WiFi on a Dell XPS L702x Laptop in Ubuntu 11.04
I have a Dell XPS L702x Laptop and the wireless is dodgy in Ubuntu 11.04. By Dodgy I mean it drops out and doesn’t automatically connect very often especially when a Ethernet cable is unplugged. It seems the problem is that Ubuntu doesn’t get on well with wireless-N (perhaps the driver is buggy?). I fixed […]
WordPress failing to email me about new blog comments
Did you know that WordPress sends you emails when you get a new blog comment? I didn’t – because it has never worked for me. But once I knew it was supposed to email me I looked into it and found a fix. Setup: My setup is running WordPress.org on a Ubuntu 9.04 box called […]
Session sharing in PHP – The easy way
I used to think that a hard part of scaling a website from one webserver to two webservers was sharing the sessions between the machines to keep the users logged in whichever machine they were served by. I was pleasantly surprized that it is possible to accomplish sharing sessions between two servers by changing only […]
WordPress spelling auto-correction now fixed
In WordPress 3.0, my WordPress logo image (on the left) broke. So I opened a bug and six weeks and 100 bug comments later, I have upgraded to 3.01 and it is working again. Thanks guys! The reason why the logo image was broken was quite interesting(?)… In v3.0 WordPress automatically started auto-correcting Wordpress to […]
WordPress Tag Cloud – How to cap the font size
On the Bitvolution WordPress theme, the sidebar is quite small (only 220px) and the default WordPress tag cloud widget was producing tags that were clipped in a ugly manner. By default, the WordPress tag cloud widget has a maximum font size of 22px so I was looking for a way to reduce it. Note: If […]
Firefox 3.6 opacity crash in Linux
A website that I was working on suddenly started crashing Firefox 3.6 on my PC (Ubuntu 9.10, 64bit). I’m talking a full out hang with 100% CPU usage and a frozen mouse and keyboard and the only way to recover is to remote login from a 2nd PC and kill the Firefox process. I found […]
How to have a hidden wordpress page
A typical use case for a hidden page might be so you can store your website licensing agreement or image attribution links without having it explicitly in the main navigation links – most folk link to their licensing agreement in the footer. If you want to have a page on your self-hosted WordPress website that […]

Installing fonts in Ubuntu
If you have a font file with a “ttf” extension you can easily install it in Ubuntu (v9.04) and use it in applications such as the Gimp. Essentially, all you have to do is drop it in the correct folder: cd /usr/local/share/fonts If the truetype/custom directory doesn’t exist already: sudo mkdir truetype sudo mkdir truetype/custom […]
