PyCon SQLAlchemy tutorial slides

My SQLAlchemy tutorial went pretty well for the most part. It was a fast pace but most people kept up pretty well. If I did it again I would add more of an intro to ORM in general for people who had never used one, but over half the attendees had used SO or django's or tried SA already. I would also paste more code from my slides into the samples download to save people typing during the exercises (I had some, but I would do more next time).

I think most people liked it; the main exception was one fellow who was in way way over his head and visibly pissed about it. (I used a list comprehension at one point and he had no idea what it was.)

The slides are here. (The .py files referred to in the slides have also been moved to the jellis/ subdirectory.)

You'll never get the level right for everyone and it's a lot better to pitch higher than lower. At least the guy went away with a big list of things to learn about which should be worth the price of admission itself :-)

As it is, I've looked through the slides and I really, really wish I'd been there .. Congrats!!

I knew the tutorial would be over my head (it said so right there in the course description) and signed up anyway for precisely the reason Tim gives. Realistically, I'm not going to learn SQLAlchemy and stored procedures and triggers and so on in a couple of hours. But now I know what I've got to learn if I want to use any of these tools.

That having been said, I did at least know what a list comprehension was, and I've used SQLObject a bit.

My only suggestion would be to encourage pairing on your exercises. I didn't have a clue where to start and didn't at first have your slides to refer back to; I don't think I was the only one. So waiting around for the solution was a bit of dead time.

Cheers!

Pairing is a good suggestion. Thanks!

is there possibility to get complete lecture toghether with slides?

The best would be flash movie (or sth) but simple audio file would be enough.

If not, Jonathan - maybe you can record it?

Sorry; I'm happy to post the slides but I don't have an extra three hours to repeat the lecture/explanation into a mic. (Let alone post-processing to clean things up.)

PyCon Python IDE review

I presented an IDE review at PyCon last Friday. It was basically a re-review of what I thought were the 3 most promising IDEs from the Utah Python User Group IDE review , to which I added SPE, which was by far the most popular of the ones we left out that time. The versions reviewed are: PyDev 1.0.2 SPE 0.8.2.a Komodo 3.5.2 Wing IDE 2.1 beta 1 I'd intended to base my presentation around a comparison of writing a smallish program in each of the IDEs, but the more I tried to make this not suck, the more I realized it was a losing proposition. Instead, I decided to try to focus on the features in each that most set them apart from the others (both positive and negative); this seemed more likely be useful. (I did a new feature matrix for this review, which is included after my comments. The slides I used are also up, at http://utahpython.org/jellis/pycon-ides.pdf , but aren't very useful absent video of the presentation itself. Hence this post.) PyDev PyDev has g...

Why PHP sucks

(July 8 2005) Apparently I got linked by some PHP sites, and while there were a few well-reasoned comments here I mostly just got people who only knew PHP reacting like I told them their firstborn was ugly. These people tended to give variants on one or more themes: All environments have warts, so PHP is no worse than anything else in this respect I can work around PHP's problems, ergo they are not really problems You aren't experienced enough in PHP to judge it yet As to the first, it is true that PHP is not alone in having warts. However, the lack of qualitative difference does not mean that the quantitative difference is insignificant. Similarly, problems can be worked around, but languages/environments designed by people with more foresight and, to put it bluntly, clue, simply don't make the kind of really boneheaded architecture mistakes that you can't help but run into on a daily baisis in PHP. Finally, as I noted in my original introduction, with PHP, ...

A review of 6 Python IDEs

(March 2006: you may also be interested the updated review I did for PyCon -- http://spyced.blogspot.com/2006/02/pycon-python-ide-review.html .) For September's meeting, the Utah Python User Group hosted an IDE shootout. 5 presenters reviewed 6 IDEs: PyDev 0.9.8.1 Eric3 3.7.1 Boa Constructor 0.4.4 BlackAdder 1.1 Komodo 3.1 Wing IDE 2.0.3 (The windows version was tested for all but Eric3, which was tested on Linux. Eric3 is based on Qt, which basically means you can't run it on Windows unless you've shelled out $$$ for a commerical Qt license, since there is no GPL version of Qt for Windows. Yes, there's Qt Free , but that's not exactly production-ready software.) Perhaps the most notable IDEs not included are SPE and DrPython. Alas, nobody had time to review these, but if you're looking for a free IDE perhaps you should include these in your search, because PyDev was the only one of the 3 free ones that we'd consider using. And if you aren...
