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 …

Re-raising Exceptions
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 …FlatAtompub
A little while ago I decided to whip up a small Atompub server to get my head around the Atom Publishing Protocol. I called it FlatAtomPub because it was just storing stuff in flat files. I’m not committing to that name. It was also a chance to kick the …
2 Python Environment Experiments
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 …
lxml.html
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 …
Workingenv is dead, long live Virtualenv!
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 …
Logo
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 …
Prism
I’ve seen talk of MS Silverlight and Adobe AIR. People talk them up like the future of web applications or something. I don’t know much about them, but I almost completely certain I don’t want anything to do with them.
Here’s a general rule I have …
Java BDD
I notice there’s another Behavior Driven Development framework for Java called Instinct (via). I have commented on BDD before.
Here’s an example test:
import static com.googlecode.instinct.expect.Expect.expect; import com.googlecode.instinct.marker.annotate.BeforeSpecification; import com.googlecode.instinct.marker.annotate.Context; import com.googlecode …
What PHP Deployment Gets Right
With the recent talk on the blogosphere about deployment (and for Django, and lots of other posts too), people are thinking about PHP a bit more analytically. I think people mostly get it wrong.
There are several different process models for the web:
- CGI, where every request creates a new …
