Dumb LCA Keysigning Oops :-)

Posted on by

Found the reason why my MD5 sums didn’t match anyone elses! I stupidly had written down the MD5 checksum for the file containing the MD5 checksum for the key signing list, and not the MD5 for the file I wanted to!

The actual MD5 checksums were correct.. ENOCAFFEINE!

Off to Linux.Conf.Au 2005

Posted on by

Well today we’re off to Linux.Conf.Au 2005, and Monday 4:10pm I’m going to be presenting at the Clustering Mini-Conference with a talk called:

Herding Cats – Clustering with Linux at VPAC

The Victorian Partnership for Advanced Computing (VPAC) is Victoria’s
peak HPC organisation, and Linux based clustering has become the mainstay
of our HPC facilities.


As VPAC’s Deputy System’s Manager I will be taking you on a tour of the
clustering technologies we use and how Linux and Free/Open Source software
helps us meet the needs of our users (and where it doesn’t). Finally,
we will take a peek at what promise future technologies may hold for
our organisation.

Wish me luck!

Follow Up to “Administrator” Post

Posted on by

Well, I got an email from Todd in reponse to my posting his story about not being able to contact me. Todd runs the Fall Creek Place Community website that looks like a nice idea, an attempt to help foster a real community through the web (in addition to real life, needless to say!).

Turns out what he was after was not quite related to the xBackends.php script that generates my RSS feed, but the little HTML tags that I used to tell Firefox and Konqueror/Akregator that there is an RSS feed associated with the page that they are viewing, and so to show the little RSS indicator at the bottom of the frame.

I wrote about it before, somewhere, but to recap here’s the little HTML tag that does the magic.

Administrator inaccessable, user concerned.

This arrived in the submission basket today..


Today, a user searched frantically for some way of writing to the Administrator, Chris Samuel. Having found nothing, he concocted a fake news story as a thinly vieled attempt at a complaint, in hopes that said Administrator would consider creating some link to internal or regular email, so that said user may ask him a question about his xBackends configuration for PostNuke.

Film at 11.

– Todd.

🙂

Todd, it’s easy – you just email to:

chris

csamuel.org

and it will (should!) get to me, spam filters allowing…

Note that I’m off on Sunday to Canberra for LCA 2005 and so life is a bit hectic at the moment, but I’ll do my best to answer!

Google Maps meets satellite photography

Posted on by

The ever-excellent Rich Boakes pointed me at his weblog story about the (almost) killer app from Google, where their existing Google Maps tech meets satellite photography from their purchase of Keyhole.

Here is a stunning example, a zoomed in image of Chicago Airport. Another is the fact that you can routeplan, although it’s interesting to note that they’ve decided to make certain government buildings stand out by censoring them from the imagery. You could probably find the interesting ones by scanning the imagery looking for the distinctive grey fill in. 🙂

Now what we want is imagery for the rest of the world!
