How I Partition Disks

Having had a number of hard drives fail over the years I use RAID whenever possible to reduce the probability of data loss caused by hardware failure. It’s unfortunate that some machines make it impractically difficult to install a second hard drive (my laptop and some small form factor desktop machines I have given to [...]

Storing a GPG key

Chris Lamb has suggested storing a GPG key on a RAID-5 device [1]. The idea is that it can be stored on several physical block devices such that losing just one will not give the key to an attacker.

A default GPG secret key will be about 1.2K in size (3 sectors of a hard [...]

Asus EeePC as a Router

It seems to me that the Asus EeePC (a $AU499 ultra-light laptop with only flash storage) would make a decent router.

Often full desktop PCs are used as routers because they run the most common software and have standard interfaces. There have been dedicated router devices with flash for a long time, but without the [...]

Secure Computation on an Insecure Base

Julien Goodwin asks whether an insecure platform can perform secure computation [1]. My immediate reaction was to recall Charles Babbage’s quote On two occasions I have been asked,—”Pray, Mr. Babbage, if you put into the machine wrong figures, will the right answers come out?” [...] I am not able rightly to comprehend the kind of [...]

Free Software Community and forking

I just read an interesting approach to finding a life partner [1]. A summary is “There is a sad truth to the world today. I am part of a dying breed of people known as “shell users.” … Because there are fewer and fewer of us, I must help keep our lineage alive. I am [...]

LCA 2008 Security Blogging Contest

I have decided to run a contest for security related blog posts that appear on Planet Linux Conf Au [1]. That Planet is for people who are attending Linux Conf Au [2], and the prize (or prizes) will be given out at the conference.

The aim will be posts on the topic of computer security [...]

Gifts for Strangers

Leon writes about giving a stranger $1 to help him get a train ticket.

Recently I saw something similar, a lady was giving balloons to children in the Bourke St Mall in Melbourne just after 9PM. I asked her about this (I couldn’t see a logo on the balloons and wondered how she was making [...]

Bruce Schneier Advocates no Encryption

Bruce has written an interesting post about wireless encryption [1]. His main ideas seem to be that it’s nice to provide emergency net access for random people, that attempting to secure a wireless network only causes more problems when (not if) it is broken, and that your machines which are mobile need to be secure [...]

Differences between Distribution Kernels

It is not uncommon to run a Linux system with a kernel that was compiled for another distribution. One reason for doing this is the difficulty in compiling and testing a kernel to make sure it will do what you require. It’s not THAT difficult for someone who knows what they are doing, but if [...]
