Google Calendar supports CalDAV

Google Calendar has added support for CalDAV. For Mac weenies, this means you can share calendars across multiple Macs, adding and removing events via iCal. And you can do it without paying for MobileMe.

Wonderful stuff!

Terminal.app hangs at startup

I just got bit by this bug, under OS X 10.5.4. The symptoms are that sudo hangs, and Terminal.app hangs when opening a new tab or when starting up. Console.app shows messages of the form

7/24/08 7:04:44 AM kernel devfs: ttys001: name slot allocation failed (Errno=17)

rprr posted a workaround in the above thread which worked for me. I don't know how to link to specific messages in the discussion thread (or whether that's even allowed under the terms of use, egad), so here's a recap:

1. Started Terminal. It hung up. Did Force Quit and Sent Crash report to Apple.

2. Since I had a working X11 application, I used it to open about 10 xterms using the Applications->Terminal Menu of X11.app

3. I started Terminal again. Now it works.

Anarchogeek: Beyond REST? Building Data Services with XMPP PubSub

Addresses a few problems which I've never had to face. Still, lots of interesting ideas to chew on. Hints at techniques that could be applied even to low-volume web services which involve long-running server-side computations.

Many little parasites add up to one big biomass - earth - 24 July 2008 - New Scientist Environment

The main point of the article is that parasites are much more populous than previously believed. But this quote was the most interesting:

Many little parasites add up to one big biomass - earth - 24 July 2008 - New Scientist Environment:

"Dobson says he has work in press showing that parasites contain between 10 and 1000 times more pollutants than their hosts. He suggests parasites might play an important role in cleaning up the animals they inhabit."

So they castrate you, but they also keep you clean...
