My wife's WinXP box died, again. I've been running the box for two years and that is just too long for windows. It really needs a full reformat and reinstall. But I don't have the time to deal with it now so I decided to instead to put Linux on my wife's machine. 98% of her time is spent in FireFox so she doesn't really care what the OS is. Wanting something easy I decided to try out several 'live Linux' distributions. These are distributions that run completely off a CD, no hard disk installation required. The one I found worked best on my wife's Dell was Mepis but even that will never stay up more than two days.

Why I'm Not Happy With My PI Engineering Y-Mouse
I bought PI Engineering's Y-Mouse adapter for USB a few months ago to hook my Apple Macintosh G5 into my PS/2-VGA KVM and the results have been deeply frustrating.

Writing Backwards Compatible XML Schema 1.0 Schemas Using the XML Ignore Rule
Writing a XML Schema is a challenge but as the first part of this document explains, writing a V2 schema that can accept V1 documents is in most cases impossible if you use XML Schema 1.0. In other words, if you want to write a backwards compatible schema you probably won't be able to do it using XML Schema 1.0. In an ideal world we would take the lessons learned from XML Schema and use them to start over, probably with RelaxNG. But until we can move over to a new standard we need a way to enable backwards compatible schemas to be written in XML Schema 1.0. Therefore the second part of this document explains how to use the XML Ignore Rule in conjunction with XML Schema 1.0 in order to create a validator that enables one to write backwards compatible schemas. The XML Ignore Rule can be best summarized as "if you don't recognize it, ignore it."

Mark Nottingham, XML Schema, Web Services & SDO
Mark Nottingham's article on XML Schema and Web Services is well worth reading. Of course I say that because I mostly agree with him. What I don't agree with Mark on is that RDF is the right way to go, but I am beginning to wonder if perhaps SDO is.

Escaping Excel X to OOo 1.1.2
I've previously described just how deeply awful Excel X is when using Visual Basic. But things recently got even worse when I found a bizarre bug in Excel X's For Each operator that prevented me from iterating on an array. Desperate for some kind of alternative I checked out Open Office for the Mac again and found a new version, 1.1.2, which is significantly better than the previous version and fits my needs much better than Excel X.

N:1 Web Service Applications – Getting from V1 to V2
Below I walk through the issues an implementer faces in moving from V1 to V2 of a Web Service application. I am limiting my investigation to a sub-set of Web Service applications, a N:1 Service. That is, a Web Service application with many clients (N) for which there is only one instance of the Web Service application itself (1).

Rsync, RsyncX 2.1 & OS X
I really needed to backup my system. I had evaluated a bunch of backup software when a friend (who shall remain nameless to protect the guilty) pointed out Rsync and RsyncX 2.1. Rsync is a command line open source program used to do sophisticated data backup. RsyncX is a 'friendly' front end to Rsync. Rsync by itself is about as friendly as an angry viper. RsyncX is a little less unfriendly, say about the level of a club to the head. After seven or so hours I finally managed to get everything working. Below I give step-by-step instructions on how I used RsyncX to set up both my local and remote backups. My take away from this experience is that I should have just bought backup software.

Printing, IPP, OS X & Defeat
Sometimes you just have to know when to give up. I've been trying to figure out how to get my wife's Linux box to print on the printer I've hooked up to my OS X box. I configured the printer. I set up printer sharing. I connected to the CUPS server locally without problem. Then I tried to connect remotely. No luck. I edited /etc/cups/cupsd.conf to add the IP address of the linux box. No luck. At some point you just have to know when to give up. I give up. If there is a way to get printer sharing over IPP working with an OS X box as server and a Linux box as client I can't figure it out.
How to mount a Firewire Drive using an iLink (1394/Firewire) port with Mepis Linux Live CD on a Dell Inspiron 8200
What To Do
- Open a root terminal and type in "modprobe ieee1394 ; modprobe ohci1394 ; modprobe sbp2"
- Download rescan-scsi-bus.sh and then "sh rescan-scsi-bus.sh".
- "Fdisk -l" to get a list of all available drives. You should be able to see the firewire drive listed along with what devices (e.g. /dev/sda1 or /dev/sdb1 or whatever) its partitions have been assigned to.
- For each partition you want to mount (e.g. for each /dev/sda1, /dev/sda2, etc.) create a directory somewhere to mount to. I created /mnt/sda1, /mnt/sda2, etc. Then run "mount -t auto /dev/sda1 /mnt/sda1" where you replace sda1 with the actual device of the partition you want to mount. Repeat for all partitions you want to mount.
Goland, Director Goland
I just received a promotion to "Director of Technology" at BEA! Near as I can tell the biggest change the new title will bring is that it officially gives me permission to stick my nose into even more things at BEA than I usually do.
