A group in the US has taken out a lawsuit to try to prevent the Large Hadron Collider starting up. Why? Because it might destroy the earth, of course.

I hate to say it, but that’s what happens when popular science magazines blindly give credence to any old nonsense wittered by someone with a science degree. Planet-eating particles, my arse.
The ActiveX effect February 18, 2008
Posted by andrewgdotcom in Microsoft, Ranting, Web.4 comments
In my current job, Microsoft Sharepoint rules. The decision was made long before my time to employ it as the common document repository, and for most people it works reasonably well. I have to force myself to use it though, and I can distil the reasons down to one root cause: ActiveX controls.
In its vanilla, static-page form, Sharepoint is barely functional. It takes a minimum of four clicks (open, edit, modify, save) to change a radio-button option. Checking files in and out is a pain – it’s easier to just overwrite. And I’ve never managed to attach a file to a list entry. To make it really useable, you need to run IE.
Oh wait, you’re using a Mac. Well you can just piss off then.
It’s interesting that Microsoft poured thousands of programmer-hours into developing an alternative to JavaScript and not one of the other browsers makes any attempt to support the resulting spec – this in a world of Mono, Samba, Moonlight and OpenOffice. MS dropped IE support on the Mac but keep pushing ActiveX in their server products. I’m no expert, but the only thing I see ActiveX doing that JS can’t is installing software updates without bothering the user with dialog boxes. Which is a good indication of why nobody else will touch it with a barge pole.
The problem is not confined to Sharepoint. The motivation for this post was finding that Microsoft’s certificate management server requires scripting to be turned on (it doesn’t say what sort of scripting, but it isn’t JS) in order to process a simple form that could have been written in 1995. In this case there was no option but to boot up the VM and use IE.
So what to do? Struggle manfully with Sharepoint’s prehistoric static interface or retreat into the VM, cut off from my usual editing suite – Office X for Mac. Somebody somewhere is no doubt enjoying this juicy irony. But it’s not me.

I was reading up on some of the background to Garrett Lisi’s interesting new paper when I came across this gem via Sabine Hossenfelder’s blog.

If that makes your brain melt, Bee also has some more frivolous stuff.

Galway LUG is organising a Linux installfest on Saturday 17th from 10am-noon in the DERI building, Lower Dangan (map). This is a chance for you to bring along your old laptop/desktop and give it new purpose in life! If you have thought about trying Linux, but haven’t yet summoned up the courage, here is your chance to get some hands-on help. We will have several experienced users on hand to help you select, install and configure your first Linux.
A word of warning: if you have data on your hard drive, please BACK IT UP before bringing your machine. Galway LUG and its volunteers cannot be held responsible for loss of data. It is your responsibility to have current backups.
See you there!

On the face of it, this sounds excellent. I’ll be interested to see just how many of these hotspots materialise…
Avahi and dot-local addresses on Ubuntu Gutsy September 28, 2007

I’ve noticed a problem with avahi and *.local addresses on ubuntu gutsy
- this will probably have cropped up on other distributions, or will do
soon. It is related to the similar Mac *.local problem.
It is thus: if you have avahi (aka zeroconf) installed, *.local
addresses are resolved via mDNS first. The default config of avahi is to
fail if mDNS is enabled and the host is not found in mDNS. This means
that you cannot resolve addresses under .local which are
in DNS but not mDNS.
To fix, edit /etc/nsswitch.conf and remove the text “[NOTFOUND=return]“
as follows:
hosts: files mdns4_minimal dns mdns4 #hosts: files mdns4_minimal [NOTFOUND=return] dns mdns4
You then need to restart the problem software. Avahi still works, but
will fail over to standard DNS if the host cannot be resolved via mDNS.

BarCampGalway was great. An interesting and eclectic collection of talks and a serious dose of geek craic in the Westwood afterwards. Talks I attended at least some of included:
- Moving between Windows and Ubuntu by James Cooley
- Django for WebApp development by Kevin Noonan
- Machine Learning by Aidan Finn
- Microsoft Silverlight by Martha Rotter (cross-platform? Really?)
- Gamepad driven text editing by John Sturdy (so what’s Emacs?)
- Perl lightning talks by Tim Bunce (apologies for typing furiously during it, but I was listening)
- Drupal by Vincent Jordon
- Demystifying Internet Marketing by Alastair McDermott
All good clean fun. Thanks to John, Aidan and Conor for organising.
Hidden SSIDs = broken September 15, 2007
Posted by andrewgdotcom in Networking, Wii.add a comment
From this report :
Contrary to a common belief that the SSID is a WLAN security feature and its exposure a security risk, the SSID is nothing more than a wireless-space group label. It cannot be successfully hidden. Attempts to hide it will not only fail, but will negatively impact WLAN performance, and may result in additional exposure of the SSID to passive scanning.
I can tell you from bitter experience that this is true. This link was brought to my attention a couple of months ago by Mark Leyden when we were trying to debug some mysterious WLAN problems in work. We had been using SSID hiding, and some machines were continually disconnecting and reconnecting to the WLAN. We turned on broadcasting of the SSID and most of the problems just went away.
People in work still come up to me and say “I can see the SSID of the work WLAN – is that such a good idea?” and I have to keep explaining.
Later, I discovered that IBM T60p laptops wouldn’t connect to my home WLAN, even though my trusty iBook never had a problem (my trusty iBook never has a problem). I turned on SSID broadcast, and it worked.
I thought at the time that maybe this was causing my mysterious Wii network connection failure, but didn’t test it (I haven’t used the Wii in forever). Today I did. It works.
Today’s moral – a network with a hidden SSID is a broken network. End of story.
