The long wait for my second post on GTD is over (I'm looking at you, Scottogroom). It's been nearly a year since I tried GTD and quickly fell off the wagon. I'm planning to give it another go in earnest soon, but even without the full system I've incorporated a lot of useful ideas into my daily life. Read more about it over at my work blog. You can also add our RSS feed to your web-o-stream if you care what I do all day.
I've now twice had to deal with Mac OS 10.7.4 (Lion) having real problems with connecting to either of the two wifi networks at the University of Geneva. One is a standard setup with a captive portal, and the other is the EU shared "eduroam" infrastructure. In both cases Lion's handling of certificates gets somehow messed up (the web has many opinions but no obvious solutions as far as I can see). Anyway, after twice spending an hour searching for a solution the only thing I've come up with so far which seems to work (but then again, ask me tomorrow) is:
Completely switch off and reboot (NB: choosing "restart" from the apple menu doesn't seem to work).
C'mon Apple. Sort yourselves out!
UPDATE: This doesn't actually seem to work all the time. I did finally find a more technical explanation of what exactly is going wrong, as well as another solution (currently working) here.
