Martijn Faassen (whom apparently started EuroPython years back) did the funniest lightning talk at this year’s EuroPython, promoting his new web framework Grok, built on Zope:
Talking to him, he seemed very passionate to reinvigorate Zope through Grok. I must say I think both Zope 3 and Grok are quantum leaps forward compared to Zope 2.x, and I’m sure they’ll pick up more developers over time. It’s going to take some time for me, though, who got pretty burnt by the Zope/ZODB combination, to give it another try again. And I don’t think I’ll ever trust a database that doesn’t explicitly enforce a schema; it’s just a recipe for maintenance hell.
This is of course pretty controversial stuff, and in all honesty, Arlo only has his own data and the feedback of 6 teams that tried it as supporting evidence that it works. Of the 6 teams, all had productivity boosts. 4 teams continued, 2 stopped. The reasons why they stopped was interesting, though: they liked specializations, and were happy with slightly less productivity.
The final practice Arlo described was team-owned tasks. Avoiding assigning tasks to people is very important to encourage team responsibility, which leads to team accountability, which is a necessary requisite to building strong self-organizing teams.
The normal approach is to put the most qualified implementor on a task. Naturally, that should ensure the task got done faster and better, right? Well, just to see how it worked, they once tried the exact opposite: putting the least qualified implementor on a task. Again, what they found was astonishing.
Arlo’s team wanted to be extreme, and they started with one of the XP practices, pair programming. Going extreme meant that they would pair program all the time. No code produced by a single person was allowed to be checked into the repository.
But, pair programming is also a pretty new and relatively undefined practice. There were still a lot of questions open, among them:
The most interesting and eye-opening talks at EuroPython 2007 were probably Arlo Belshee’s talks on agile methodologies and his team’s experiments and results in that regard. The following blog posts summarizes what I learned from listening to his talks, doing his XP workshop, discussions with him, and digging up related information on the web (such as a paper and a podcast). I strongly believe this could be the next phase in how we develop software, and I hope I’ll be able to whet your aptetite for change as well
ODF is a completely free and perfectly viable format for such information. Despite Microsoft attempts at stating otherwise, it has already been proven to be able to store any information MS Office needs to store; there’s not even any reason for OOXML to exist. It’s such an obvious attempt at confusing the public; let’s show we’re not confused.
ITC has a RESTful Web Services podcast where Jon Udell talks with Leonard Richardson and Sam Ruby about their new book. They even discuss some things like doing transactions with REST.
I have good luck with this trick on several Sony Ericssons (including W800i and now K800/K800i):
edit ABDeviceCommandSets.plist in the /Applications/Address\ Book.app/Contents/Resources/Telephony.bundle/Contents/Resources/ directory with the editor of your choice
find K700 and create an identical line underneath it, replacing K700 on the new line with your (hopefully compatible) model number; in my case I added two lines, one for K800 and one for K800i, just to be sure
