A while ago I wrote a blog post debunking the idea that swap should be twice as large as RAM . The issue of swap size has come up for discussion in a mailing list so it seems that it’s worth another blog post.
In my previous post I suggested making swap space [...]
I recently had a chance to briefly play with the new Samsung Galaxy Camera . The Galaxy Camera is an Android device with a 4.8″ display (the same size as the Samsung Galaxy S3) that has a fairly capable camera (IE nothing like a typical phone camera). It runs Android 4.1 (Jelly Bean) and the [...]
My new Samsung Galaxy S3 phone takes a micro-SIM (see the Wikipedia page about Subscriber Identity Modules for details ). All my other mobile devices take a mini-SIM so I can’t just put the SIM from my old phone in my new phone. I’ve just made my second application to Virgin Mobile for a new [...]
A member of SAGE-AU  found two ATM skimmers  and gave me permission to publish his description and analysis of the situation. I’ve lightly edited this from a mailing list post to a blog format with permission from the author. This Courier-Mail article refers to the skimmers in question .
People were wondering what [...]
Care2 has an interesting article about people being offended by a picture of a poor Afro-American boy using an iPad . It seems that people object to poor people having what is in many ways the greatest educational tool available because it can also be seen as a status symbol. I wonder if one of [...]
My new Samsung Galaxy S3 arrived a couple of days ago. Kogan added to the weirdness in their shipping that I documented in a previous post  by shipping the two phones on consecutive days with separate invoices for $789 each (as opposed to the $449 that I paid). This means that if customs were [...]
I’ve just installed BTRFS on some systems that matter to me. It is still regarded as experimental but Oracle supports it with their kernel so it can’t be too bad – and it’s almost guaranteed that anything other than BTRFS or ZFS will lose data if you run as many systems as I do. Also [...]
I just watched an interesting TED talk by Pankaj Ghemawat (of which the most important points are summarised in a TED blog post) about the world not being as globalised as people expect . One point is that only 2% of traditional voice phone calling minutes (and ~6% when you include VOIP) are for international [...]
I have just ordered two Samsung Galaxy S3 phones and matching cases from Kogan. The price was good and Kogan gave me 30 cents discount as part of a verification process. Instead of billing the full amount for a large order (for which the cutoff is somewhere between $25 and $1014) Kogan will deduct a [...]
Steven Johnson gave an interesting TED talk about where good ideas come from . He starts by attributing coffee replacing alcohol as a standard drink for some good ideas and then moves on to how ideas develop.
Erez Lieberman Aiden and Jean-Baptiste Michel gave an interesting and amusing TED talk about the ngram analysis of [...]
