Following that last note, we need a new maintainer for python-dateutil. It has a non-trivial number of modules depending on it, including from high-profile companies. Yet, I'm not maintaining it anymore for quite a while, and the new maintainer turns out to not have time for it either. If you are an active Python developer that cares about the module and cares about its community, please do get in touch. Please do consider whether you'll have time and enough interest on the module to provide a healthy maintenance story.

This is why we unschool our kids, to let them hack their own education!
 
Great 11-minute TEDx talk from a 13 year old about how he is hacking his education in the pursuit of happiness and health.

Look what came in the mail today: Goodies from #StackOverflow! Stickers, nice pen and a Desktop Corn Toss Game!

Now I need to make room on my desk for that...

Great video of the first time the #sagaoseberg sailed, on returning from Oslo, including some rowing at the end.

I wasn't able to come along on that trip, but my son-the-viking is on board.

Now there is a #stackoverflow #python question that shows research effort.

The cause is a 10-year-old bug, but still, the poster put in real effort trying to understand scoping rules.

Hi Ayden,

Sorry, no, emailing me Python programming problems doesn't scale; I simply couldn't keep up. Post your questions to Stack Overflow, or if not on topic, try the Python Tutor mailinglist (https://mail.python.org/mailman/listinfo/tutor) or perhaps the Python Chat room on Stack Overflow (http://chat.stackoverflow.com/rooms/6/python, you need 20 or more reputation to speak, please do check out the chat room rules at http://sopython.com/pages/chatroom).

That way you and everyone else can make use of the collective wisdom of the internet, not just from one person.

#Python  iterator suprise on #StackOverflow ; why does it appear that the `next()` calls have no effect and the `for` loop is behaving as if it has its own private iterator?

Try to work out what is happening before you read my answer.

Do you know how to build a strawbale house or want to know how to use cob? Always thought composting was a good idea but don't know how to start? Worried using petro-chermicals is going to be unsustainable in the long run but don't know what to use instead?

The ultimate, clear, entertaining and most of all complete explanation that I hail from The Netherlands, and from Holland.

A little rowing demonstration. Not that we really know how to yet..

Yeah, that's me behind the project leader during the interview, pretending to be a viking. My son-the-viking is also present on that ship.

Today she's in Oslo, having sailed up the fjord. If you want to go visit her, she's at Akershus Festning (the fortress) between 11 and 16, taking tourists for short tours. Unfortunately, I couldn't come along for the trip, but my son is there.
