Jacek Konieczny has written the wholly fantabulous PyXMPP, which implements Jabber clients and servers in Python. Now, Google Talk is a Jabber server, but it needs TLS support before it works. The code is all there, but the echobot example in the download (look in the examples directory) doesn't show you how. It's not that hard though -- here's the patch I needed to make it work:
--- echobot.py 2005-12-26 07:25:55.000000000 -0800
+++ echobot2.py 2006-10-25 04:25:02.000000000 -0700

That makes the __init__ method for the client:

Too easy.

I was in an unrelated meeting at work today, and it came up that the first annual Anti Borg scholarship is closing it's application window in a few days. I thought it was worth mentioning here, in case there are people who are interested in applying. The basic deal is:
Dr. Anita Borg (1949 - 2003) devoted her adult life to revolutionizing the way we think about technology and dismantling barriers that keep women and minorities from entering computing and technology fields. Her combination of technical expertise and fearless vision continues to inspire and motivate countless women to become active participants and leaders in creating technology.
As part of Google's ongoing commitment to furthering Anita's vision, we are pleased to announce the 2006 Google Australia Anita Borg Scholarship. Through the scholarship, we would like to encourage women to excel in computing and technology and become active role models and leaders.
Scholarships will be awarded based on the strength of candidates' academic background and demonstrated leadership. A group of female undergraduate and postgraduate student finalists will be chosen from the applicant pool. The scholarship recipients, selected from the finalists, will each receive a $5,000 AUD scholarship for the 2007 academic year.
All finalists will be invited to visit Google Sydney in November 2006 for a networking retreat. It will include workshops with a series of speakers, breakout sessions and social activities. The visit is meant to be an opportunity for all finalists to meet and share their experiences.
If that sounds interesting to you and you're a lady studying computing or a related field, then you should checkout the announcement page before it's too late.

These guys really did deliver 1,000 pizzas to Google's Mountain View campus. We even ate them. I guess that's one way of getting publicity...

The kids are the in the Kinderplex today (the Google-only child care center). It's the first time I've dropped Matthew off for care and he hasn't gone ape -- I think it's because he loved the center so much... There are computers in every room, and it's probably the nicest laid out and supplied child care center I have ever seen. It makes me wonder if I should be sending Andrew there next year for pre-school.

The guys behind the PKD android project -- very cool in a geeky way. Jimmy Carter -- very cool in an unbreaking the world way.
Oh, and apparently you're always a President, even if you're no longer in office, and you're meant to stand when a President enters the room. Oh, and clapping means "yes".

Gordon at work asks me what is happening with www.frozenchicken.com. If you hit the site, then you get the Google search interface. This is because of the DNS configuration for the domain:
challenger:~# host www.frozenchicken.com
www.frozenchicken.com is an alias for www.google.com.
www.google.com is an alias for www.l.google.com.
www.l.google.com has address 66.102.7.147
www.l.google.com has address 66.102.7.99
www.l.google.com has address 66.102.7.104
www.frozenchicken.com is an alias for www.google.com.
www.google.com is an alias for www.l.google.com.
www.frozenchicken.com is an alias for www.google.com.
www.google.com is an alias for www.l.google.com.
You can see that www.frozenchicken.com is an alias for www.google.com, which in turn points to what is presumably my local cluster.
So why do all the links of the Google page then point via www.frozenchicken.com? Well, because they're relative URLs, they use the hostname from the browser.

So, Google has released a beta of their bloglines equivalent service, and given that Liferea crashes about four times a day for me I thought I would give it a go. Login et cetera is easy, and the user interface is nice and AJAXy. It's fairly intuitive as well, although when I was importing my OPML file from Liferea I missed the message at the top saying the import was in progress as first.
That said, it's been 30 minutes and it still says it's importing my 460 line OPML file. I just refreshed the page for the import, and the import stopped and said that I now had 54 subscriptions. So, I guess that means I should wait longer for the import. I'm now going to try importing over the top and see if it's smart enough to squelch duplicates.

So, I know that I have a few man pages online, but then again I wrote either the code they document, or some of the generation toolchain to create them, so I think that is different. Why does every man and his dog feel that he should put man pages online? It actually makes it really hard to search for things if the first page of Google results are the same man page over and over again from sites who seem to think that they're making a contribution to the community.
Are they just doing this to grab some pagerank?

John Battelle implies that the new search result page being testing by Google could make evilness easier in the future. The premise is that offering alternate queries might be useful now, but it would make it easier to insert paid listings later.
I'm confused though, and John doesn't have a comment link in his RSS output, so I'll post it here. Surely if Google wanted to embrace evil later, they could just direct their coders to make it happen? They already know what keywords you're searching for (i.e. Adwords), couldn't they just roll those into the page in a way which looks like search results? I see no real way this positions for future evil.
I've been keeping an eye on Google news recently, and there seems to be a propensity towards paranoia in a lot of people (for instance the gmail displaying Adwords thing). If people are bothered, why don't they just use another search engine? You can't tell me that MSN and Yahoo! are any less evil...
