My favourite speculative, scientific fiction author Harry Harrison is now blogging. This is quite timely as this week I have been re-reading “Rebel in Time” which I last read almost 20 years ago and it is still engrossing, smart and sharp. In fact, even moreso, considering Harrison writes about such then-fantastical concepts like a camera which records its images on an electronic card instead of film!
ITWire: Open source is a hot buzzword, but do you know what rights actually are granted to you when you accept the license conditions of a free software package? Or, maybe you’re a developer and you want to release your software but don’t know what the different licenses mean. Here’s an easy-to-read guide to the three main players.
I regularly get requests from people looking for a staffing/employment/recruitment database. Thus I’ve decided to write one. This will be a good opportunity for me to distil squillions of good ideas on what makes a perfect recruitment system, as well as experiment with XAML and data visualisation.
Thus, Open Recruitment is born

A terrible thing happened. I gave my mail server a routine reboot (I figured it had been a month or more since its last reboot) and OWA disappeared. Or, rather, the page just kept timing out.
Yet, the services looked healthy. The event log looked healthy except one little message that gave a clue. OWA was no longer configured correctly; it was attached to the wrong web site.
This fired off a lightbulb in my head: a couple of weeks ago I renamed “default web site” in IIS to a more meaningful name because I was about to host a few more domains. I hadn’t expected this to cause a problem – everything had been running fine. I guess the changes hadn’t really kicked in until the server reboot.
Happily, and after a few tense moments, the problem was resolved with a few PowerShell cmdlets that I found on Technet’s coverage of the Exchange management shell, namely:
Get-OwaVirtualDirectory -Server servernameto check the services installed.
Remove-OwaVirtualDirectory -Identity "owa (Default Web Site)"to remove the existing OWA virtual directory
New-OWAVirtualDirectory -Name "owa" -WebSite "websitename"to recreate the OWA virtual directory
Get-OwaVirtualDirectory -Server servernameto check all is well.
I visited the web site of a company alleging to be experts at communications solutions, Sonofon, www.sonofon.com.au.
The first thing I noticed was the “Untitled document” heading on their web site, never a good sign of things to come.
I wrote to the advertised “firstname.lastname@example.org” e-mail address listed.
Oh! It bounced back straight away. Apparently email@example.com isn’t actually a valid e-mail address at the sonofon.com.au domain.
I thought perhaps the FAQ may have more information. Obviously Sonofon don’t actually get asked many questions, or if so, the demographic is the Latin-speaking populace.
Not to worry, here’s some other e-mail addresses. I tried writing to firstname.lastname@example.org. It looked like a good starting point.
Oh! It fails too. At least this time the address obviously exists, but just hasn’t been set to allow mail from unauthenticated users.
Ok, last ditch effort – let’s try the other two e-mail addresses advertised – email@example.com and firstname.lastname@example.org.
By crikey, they don’t exist either.
Ok, this is beyond a joke. Sonofon are wasting my time. Not only do they not deserve my business but obviously they don’t want it anyway. I’m happy to oblige. After all, Sonofon have demonstrated they’re not communication experts. Do I really want a company looking after my telephony when this is the quality of their work?
Maybe I’m off the track; perhaps “communications” has a different meaning to Sonofon. Maybe they’re the guys you want when you’d rather liquidate your business than grow it.

ITWire: A simple piece on the fundamental concepts of users and groups in Linux. Sure, you can add users with a GUI, but what really happens behind the scenes? Here’s the low-down on just what makes a user exist.
