Programming languages "national brotherhood week"
Hi, I have once seen a variant of "national brotherhood week" with programming languages; 'all the python folk hate alle the perl folk and all the ... hate all the ... and everybody hates Java', or something like that, but I can't find it anymore. Does anyone remember it and is anyone able to find it? It was quite funny, I think it was more than five years ago though.

Note that there is another way to create new-style classes: __metaclass__ = type before the first class definition: >>> class Foo: pass ... >>> type(Foo) >>> __metaclass__ = type >>> class Bar: pass ... >>> type(Bar) I like this. However, perhaps other people reading my source code won't like it, because when they see 'class Foo:', they might expect an old-style class. But it's so much better to type and to read, that I prefer this. Does the Python style guide have any severe penalty for using this? regards, Gerrit. -- Temperature in Luleå, Norrbotten, Sweden: | Current temperature 05-09-25 15:19:47 11.0 degrees Celsius ( 51.9F) | -- Det finns inte dåligt väder, bara dåliga kläder. -- http://mail.python.org/mailman/listinfo/python-list

Except, of course, code that contains string literals with triple
quotes. And with a good editor, it's not too difficult to insert a # in
front of hundreds of lines (:%s/^/#/g).

However, most mail to this mailinglist has less than 0.001 spam probability. As you can see, this one had 0.048 - a vast score, almost enough to put it in my unsure box. It seems to be just not hammy enough. It's interesting to see that no none of the foul language words used by Xah Lee ever occurs in any spam I receive - spam is not that stupid.

It is, and that's very surprising, but apparantly it was not really hammy enough. But don't worry, by ham_cutoff is 0.2, and out of the 10 'unsure' messages per week, 2 are spam, 2 are ham, and 6 are, well, unsure. Note that with all my mailinglists, the number of messages handled is more than 2500 per week, so I'm very, very happy with spambayes...

The very least you can try:
import string
string.ascii_uppercase
for c in string.ascii_uppercase:
if os.path.isdir('%s:/' % c):
...
etc.
But I suppose there should be a better way.

I'd use PIL with numpy and subtract a birdless background picture from each picture. Make that binary (choose a suitable treshhold, 100 or so) and you'll get a matrix for each frame with value 1 for the position of the bird. Been there, done that, though my problem was slightly easier: I had a few dozen of equal balls flying around and all I needed was the average total position, not tracking each individually. How to do that if birds pass each other (projecting 3D on 2D) I don't know, but I'm sure it's been done before (not necessarily in Python though).

PEP 358 and operations on bytes
Hi, In Python 3, reading from a file gives bytes rather than characters. Some operations currently performed on strings also make sense when performed on bytes, either if it's binary data or if it's text of unknown or mixed encoding. Those include of course slicing and other operators that exist in lists, but also other operations that aren't currently defined in PEP 358, like: - str methods endswith, find, partition, replace, split(lines), startswith, - Regular expressions I think those can be useful on a bytes type. Perhaps bytes and str could share a common parent class? They certainly share a lot of properties and possible operations one might want to perform. kind regards, Gerrit Holl. -- My first English-language post ever was made to this newsgroup: http://groups.google.com/group/comp.lang.python/msg/f957acf785ddfb71 :) -- http://mail.python.org/mailman/listinfo/python-list
