I have background music for some songs available in both .MID and .KAR formats, but in each case it's being played somewhat faster than I'd like. What's the simplest way to create either .MID or .KAR files with the same content but at a slower tempo -- say, one slowed down by 20% or so, another by 15%, a third by 25%, and so on? Ideally...
I've been considering a templating solution, although my choices are between Mako and Genshi. I find templating in Genshi a bit ugly, so I'm shifting more towards Mako. I've gone to wonder: what is so good about the fact that Mako allows embedded Python code? How is it convenient for the average joe? Wouldn't templating JUST suffice wi...
Let's say I have a web application running on S servers with an average of C cores each. My application is processing an average of R requests at any instant. Assuming R is around 10 times larger than S * C, won't benefits from spreading the work of a request across multiple cores be minimal since each core is processing around 10 requ...
In agreement to this question, and its answer. I added the path of the egg and it worked. However, when I run python interactively and I import flup, it works without any problem or additional path specification. Where is the difference ? Edit: It appears that while doing fastcgi stuff, the .pth files are not parsed, but this is only a ...
I'd like to roll my own server so I can have my projects available 24/7 but with more flexibility than one of the free providers like github can provide.

I think the code at from Google's I/O talk on Sharding Counters is quite good, so I'm using that. But I'm not sure where I ought to be calling the increment when creating a new code. (I'm using Django, and I've ke...
If a Python 3 class is pickled using protocol 2, it is supposed to work in Python 2, but unfortunately, this fails because the names of some classes have changed. Assume we have code called as follows. Sender pickle.dumps(obj,2) Receiver pickle.loads(atom) To give a specific case, if obj={}, then the error given is: ImportErr...

I'm used that in Objective-C I've got this construct: - (void)init { if (self = [super init]) { // init class } return self; } Should Python also call the parent class's implementation for __init__? class NewClass(SomeOtherClass): def __init__(self): SomeOtherClass.__init__(self) # init class ...

However, all frameworks I saw in python (pysqlite, SQLAlchemy) store the datetime.datetime values as ISO formatted strings. Why are they doing so? I'm usually trying to adapt the frameworks to storing d...
