Poorly performing Sprint Mogul

My $dayjob bought a new Sprint Mogul (also known as the HTC Titan, or PPC-6800) to replace my personal Treo 700wx. The general verdict is that the performance of the device absolutely sucks compared to my Treo. Screen redraws and UI updates are so slow, the device may lock up or misinterpret input. Today, I […]

MacOS X Login with 802.1x

At my $dayjob, I created a fancy unified login system with OpenLDAP and NFS mounts for all the computers. (General details of which I’ll put online when I have some spare time.) So I wanted to add another layer of fun: 802.1X network authentication. In my case, it’s only for wireless (using an HP 420 […]

Debian dovecot-auth case for init script

Debian’s init script for Dovecot doesn’t cover the dovecot-auth only case (i.e. “protocols = none”). I’m starting to use dovecot-auth to handle auth requests from Postfix (it does do better than SASL in for my needs), and since I like keeping things consistent with system startup and shutdown, I changed the init script. Also submitted […]

Cables and Wiring

A lot of people ask me where I get my cables; the answer is almost always Monoprice, unless they don’t happen to have it.

Word for Mac “Save” Errors

After migrating the home directories on Windows and Mac to network mounts at $dayjob, Word for Mac started behaving badly when someone tried to save a file, giving vague errors about incorrect permissions or file naming. It turns out that Word wants to write temporary data in a folder called “/.TemporaryItems” for each user, and […]

Splitting a string in bash

I found this little trick to split a string in bash, so I’m sharing. Maybe it’s obvious to some people, but I don’t do a lot of shell scripting, so it was helpful to me. BASH: Split a string without ‘cut’ or ‘awk’

GPL Windows Drivers for Xen

I just came across this today; it’s great to see someone finally made a GPL PV driver for Windows on Xen. Although it’s highly alpha as of this writing, hopefully the community will rally around it and start patching it into something that’s production quality. I’m using Windows on Xen at $dayjob, and it would […]

Postfix 2.4.6 Fixes “noatime” Mounts

An official fix has been merged into Postfix for spools that are mounted with the “noatime” option: – On backup MX servers where the queue file system is mounted with “atime” (file read/execute access time) updates disabled, the flush daemon would trigger mail delivery attempts once every 1000 seconds, thus rendering the maximal_backoff_time setting useless […]
