In 2007 I wrote a blog post about swap space [1]. The main point of that article was to debunk the claim that Linux needs a swap space twice as large as main memory (in summary such advice is based on BSD Unix systems and has never applied to Linux and that most storage devices […]
Early this month at a LUV meeting I gave a talk with only my mobile phone to store notes. I used Google Keep to write the notes as it’s one of the easiest ways of writing a note on a PC and quickly transferring it to a phone – if I keep doing this I […]
I just read an interesting article by Brian Krebs about the difficulty in replacing credit cards [1].
The main reason that credit cards need to be replaced is that they have a single set of numbers that is used for all transactions. If credit cards were designed properly for modern use (IE since 2000 or […]
There is a BTRFS bug in kernel 3.13 which is triggered by Kmail and causes Kmail index files to become seriously corrupt. Another bug in BTRFS causes a kernel GPF when an application tries to read such a file, that results in a SEGV being sent to the application. After that the kernel ceases to […]
Late last year I compared the prices of mobile providers after Aldi started getting greedy [1]. Now Aldi have dramatically changed their offerings [2] so at least some of the phones I manage have to be switched to another provider.
There are three types of use that are of interest to me. One is for […]
Typing Animal wrote an interesting article about the dangers of stainless steel in a medical environment [1]. Apparently silver and copper are best due to the oligodynamic effect. Instead of stainless steel drinking bottles they should sell silver plated drinking bottles for kids, I’m sure that lots of parents would pay extra for that.

I am often asked about my “accent”. The most common guess is that it’s a “British” accent, while I lived in London for about a year I don’t think that my accent changed much during that time (people have commented on the way I speak since I was in primary school). Also there isn’t a […]
I’ve just been given an Armourdillo Hybrid case for the Nexus 5 [1] to review. The above pictures show the back of the case, the front of the case, the stand, and the front of the case with the screen blank. When I first photographed the case the camera focused on a reflection of […]
Aldi Mobile has made a significant change to their offerings. They previously had an offer of $35 for “unlimited” calls and 2.5G of data in a month for which they had to publicly apologise for misleading customers as 2500 minutes of calls a month (83 minutes per day) is no-where near unlimited [1]. They also […]
I’m currently using BTRFS on most systems that I can access easily. It’s not nearly reliable enough that I want to install it on a server in another country or an embedded device that’s only accessible via 3G, but for systems where I can access the console it’s not doing too badly.
