Today I received a Dell PowerEDGE T105 for use by a client. My client had some servers for development and testing hosted in a server room at significant expense. They also needed an offsite backup of critical data. So I suggested that they buy a cheap server-class machine, put it on a fast ADSL connection […]

There has been a lot of talk recently about the cost of petrol, Colin Charles is one of the few people to consider the issue of wages in this discussion [1]. Unfortunately almost no-one seems to consider the overall cost of running a vehicle. While I can’t get the figures for Malaysia (I expect Colin […] June 16th, 2008 | Tags: Best Posts, Most Popular | Category: Cars | 5 comments - (Comments are closed) A common myth in the computer industry seems to be that ECC (Error Correcting Code – a Hamming Code [0]) RAM is only a server feature. The difference between a server and a desktop machine (in terms of utility) is that a server performs tasks for many people while a desktop machine only performs tasks […] June 13th, 2008 | Tags: Best Posts, btrfs, Most Popular | Category: Ha | 7 comments - (Comments are closed) MarketWatch reports that oil prices had the biggest daily gain on record, going up $11 in one day. They claim that this is due to an impending Israeli attack on Iran and a weak US economy. $150 per barrel is the price that they predict for the 4th of July. That’s an interesting choice of […] June 9th, 2008 | Tags: Environment, Most Popular | Category: Cars | 11 comments - (Comments are closed) In May 2002 I had an idea for securing access to GNUPG [1]. What I did was to write SE Linux policy to only permit the gpg program to access the secret key (and other files in ~/.gnupg). This meant that the most trivial ways of stealing the secret key would be prevented. However an […] June 6th, 2008 | Tags: Best Posts, Debian, Most Popular, Selinux | Category: Security | 10 comments - (Comments are closed) The man page for the date command says that the %s option will give “seconds since 1970-01-01 00:00:00 UTC“. I had expected that everything that date did would give output in my time zone unless I requested otherwise.. But it seems that in this case the result is in UTC, and the same seems to […] June 5th, 2008 | Tags: Best Posts, Most Popular | Category: unix-tips | 6 comments - (Comments are closed) Nowadays it seems that most serious mail servers (IE mail servers suitable for running an ISP) use one file per message. In the old days (before about 1996) almost all Internet email was stored in Mbox format [1]. In Mbox you have a large number of messages in a single file, most users would have […] June 3rd, 2008 | Tags: Best Posts, Most Popular | Category: Mta, Networking | 18 comments - (Comments are closed) A few of my clients have asked me to configure their routers to block access to Facebook and Myspace. Apparently some employees spend inappropriate amounts of time using those services while at work. Using iptables to block port 80 and configuring Squid to reject access to those sites is easy to do. So I was […] Recently I’ve been having some problems with hardware dying. Having one item mysteriously fail is something that happens periodically, but having multiple items fail in a small amount of time is a concern. One problem I’ve had is with CD-ROM drives. I keep a pile of known good CD-ROM drives because as they have moving […] I’m currently deciding where to get a Xen DomU hosted. It will be used for a new project that I’m about to start which will take more bandwidth than my current ISP is prepared to offer (or at least they would want me to start paying and serious bandwidth is expensive in Australia). Below is […] May 28th, 2008 | Tags: Most Popular | Category: Virtualisation | 26 comments - (Comments are closed) |
