Linksys wireless gear vs. Xbox 360

Linksys wireless gear vs. Xbox 360 I’ve been trying recently to connect a wired LAN printer and my Xbox 360 to the wireless LAN in our house. This proved trickier than I expected. First off I wanted to connect my old Linksys WRT54GS v2 wireless access point to the existing wireless network, so that I could hook my printer up to it. The wireless network is using WPA-PSK authentication. I reflash the WRT54GS with OpenWrt, version 8.

Thanks to Linux desktop developers

Thanks to Linux desktop developers I’ve just caught up with 2 years’ worth of Linux desktop developments (NetworkManager works, user switching, built-in volume controls working on my laptop). I like. Thanks for all the hard work, Linux desktop developers! PS: Turning on "subpixel aliasing" has made text much more readable.

Occasional lock-ups due to Parallels & FileVault?

Occasional lock-ups due to Parallels & FileVault? I’ve been running a Windows VM under Parallels on my work Mac. I have my home directory encrypted using FileVault. I’ve had ~5 lock-ups in the past 6 months where my Mac has just locked hard. It always seems to happen when I’m using a Windows VM. I’ve allocated 768 MB of RAM to the Windows VM. The Mac has 2 GB of physical RAM.

Interesting essay on "Misunderstandings of Privacy"

Interesting essay on “Misunderstandings of Privacy” I found the article "‘I’ve Got Nothing to Hide’ and Other Misunderstandings of Privacy " by Daniel J. Solove interesting. Specifically how he tried to categorise privacy into different categories based on the kinds of problems encountered, and his discussions on privacy and the relationships between individuals and society.

3 mobile broadband on Mac

3 mobile broadband on Mac I got some mobile broadband from 3 to cope with a two-week gap in my wired broadband provision. I had some pain getting it to work on my work Macbook Pro (which is a US one) running Mac OS X Tiger (10.4.x). The software gave me an obscure error – "internal error 5370" or similar – when running the 3 Connection Manager software. According to a techie in the 3 store I went to, I needed to download the latest drivers from the 3 website.

Knowing what rpms you've just built

Knowing what rpms you’ve just built One idiom I’ve found myself repeating in various projects is a build-all script that builds multiple rpm packages in a certain order. This isn’t very sophisticated – each time I’ve ordered the packages being built manually. But how do you know what rpms you will get, when you run rpmbuild? You need to know this, so you can install the rpms. Here is a solution:

File::ExtAttr 1.08, (Open)Solaris and 2 xattr schemes

File::ExtAttr 1.08, (Open)Solaris and 2 xattr schemes I released File::ExtAttr 1.08, which has some changes to make it report errors more consistently ($! should always contain the value of errno now). It also has some build changes, which will hopefully avoid all the CPAN Testers FAIL reports on platforms that don’t have the development packages installed for using xattrs (libattr-devel rpm on Linux). I development this release on various platforms, but the most exciting one was OpenSolaris 2008.

rpm: Filtering dependencies differently for different subpackages

rpm: Filtering dependencies differently for different subpackages Recently I was trying to work out how to filter rpm Requires/Provides dependencies differently for different subpackages. I was trying to produce a subpackage that was the same as another subpackage, but stripping out some library dependencies. Call the one subpackage foo and the other foo-nodeps. (Don’t ask why I was trying to do this.) rpm has a way of hooking the dependency generation, as described in FilteringAutomaticDependencies at the Fedora wiki.


FileVault I enabled FileVault home directory encryption on my work Macbook Pro the other day, which is running Mac OS X Tiger (10.4). I was a little bit hesitant about doing this, because of various horror stories about it not working, or performance being terrible. I made sure I had a proper backup, before starting the process. The 160 GB hard disk was about 40% full before I started. It took 1.

Recycling Compact Flourescent Lightbulbs (CFLs)

Recycling Compact Flourescent Lightbulbs (CFLs) I read in Scientific American that Compact Flourescent Lightbulbs (CFLs) contain mercury, and some US stores/states have recylcing programmes at stores or kiosks. I didn’t realise they contained mercury, and probably would have just thrown them in the bin with my other rubbish.
