As seen on a thread on Hacker News about Fizz Buzz and “interesting” functional ways to solve it. Realized that there are many ways to boil the ocean, but this feels like a nice compromise between data/program separation and language. Note this is using a “Bazz” variant of the FizzBuzz problem where Bazz is printed …

Was going to post this to stackoverflow, but the question was deleted before I posted. Turned out it was a fun exercise in writing a short program. 1def head(f_in, f_out, count=20): 2 all([not f_out.write(l2) for l2 in [line for line in f_in][:count]]) 3 4head(open('/etc/passwd'), open('/tmp/p', …

Was looking around for a mail handler for Tornado, found it pretty amazing that it didn’t exist. Since I’ve only written on commercial SMTP server and have been playing with just about everything in Tornado Web at this point I figured it wasn’t too much work to whip one out.

The basic idea is to have a python class that only recomputes something hard when one of the attributes is modified. It doesn’t make sense to recompute on every modification, nor does it make sense …

I’ve been hot and heavy over django (even if it’s embedded …

Code review time… In a conversation about URL shorteners and “Coke Rewards” realized that there was a case where I needed to be able to generate safe character strings that had high reliability for input back by human beings. The typical Base62 systems where there is ambiguity between (O, o and 0) make things hard …

The project of the week, is something that I’ve been putting off for a very long time. Which is to get something running on Extra that’s more than just a nothing site. Part of the problem is that it’s a good domain name that I’ve had parked for a very long time, and it makes real $$ in parking revenue, which I would …

Part of this post is the gratuitous, gosh that was easy to integrate! Of course part is a small point that I would like developers to think about. First off here’s the code snippet, which owes it’s history to: Zendesk Remote Authentication with Django and Unicode Names and Zendesk remote authenticatin with Djnago (the …

If you have a few minutes and speak python & twisted, it would be useful to have an extra set of eyes on this section of code. The basic idea of this is to be a reconnecting thrift client, such that I can just write simple client.function(a,b,c) calls without having to worry about if there is or isn’t a client and …
