So Logo is 40 years old. I’ll take this as an opportunity to talk about Logo-the-language (as opposed to Logo-the-graphics or Logo-the-educational-experience). It’s a much better language than most people appreciate.
Logo is Lisp. It’s an old Lisp but it’s very Lisp. Let’s look at …
A lot of people have found workingenv useful, but it’s always been a bit fragile. If you’ve seen the .../site.py is not a setuptools-generated site.py; please remove it. message, you know what I mean.
For a while I tried to refactor and improve workingenv, but it …
Over the summer I did quite a bit of work on lxml.html. I’m pretty excited about it, because with just a little work HTML starts to be very usefully manipulatable. This isn’t how I’ve felt about HTML in the past, with all HTML emerging from templates …
two experiments in the Python environment. The first is virtualenv, which is a rethinking of virtual-python.py, and my attempt to move away from workingenv. It works mostly like virtual-python.py, and on systems where it works (not Windows, nor Framework Mac Python) I think it works considerably better than …

After reading Chris McDonough’s What Not To Do When Writing Python Software, it occurred to me that many people don’t actually know how to properly re-raise exceptions. So a little mini-tutorial for Python programmers, about exceptions…
First, this is bad:
try:
some_code()
except:
revert_stuff()
raise Exception("some_code failed … So, today is 9/11. I almost missed it. It’s not like it catches you by surprise, you’re not going to forget the date. But it’s just been slipping by for a few years now without much notice.
As an event it is still very important. History …
Finally, someone wrote a version of doctest for Ruby.
Recently I’ve been writing most of my tests using stand-alone doctest files. It’s a great way to do TDD — mostly because the cognitive load is so low. Also, I write my examples but don’t write my output, then …
When I was writing the summary of differences between WebOb and other request objects, to remind myself of web frameworks I might have forgotten I went to the WebFrameworks page on the Python wiki.
Looking through that page I’m reminded how many framework options there have been. And I …
