... extension module. But PyUSB wasn't releasing the GIL when doing blocking reads/writes, which was causing problems for us. So I wrote our own module using ctypes, which does release the GIL when calling the native functions. One thing to note is that ctypes won't know about #define constants and ...

... @ЯрославРахматуллин in source code I would always read it in the "this is an ugly hack job, but seems to work well enough" sense - something you'd like to clean up later, but is not urgent. I've not used it (I typically use TODO or XXX instead), but that's how I would interp...

... @LarsH: You mean e.g. an iterator that reads from a file that can be changed while reading from it? I agree that this can be a problem (which affects any library providing next() and hasNext() method, not just a hypothetical Python library). So yes, next() and has...

... So instead of ensuring that the content of the communications can only be read by the right server it ensures that it can only be read by the right process on the server. Instead of assuming that all the communications in the securely initiated session are from the authenticated user each one has t...

...hygienic macros to add these constructs to your language. A good place to read about this kind of design is Matthew Flatt's article Creating Languages in Racket. The article may be behind a paywall. You can also find more general material on this kind of design by searching for the term "domain-sp...

... Kinda... it skips a lot of disk IO though as you don't have to read/write the data twice – Greg Mar 23 '09 at 21:39 8 ...

...o be able to swap out different implementations. Facade is a higher-level (read: simpler) interface to a subsystem of one or more classes. Suppose you have a complex concept that requires multiple objects to represent. Making changes to that set of objects is confusing, because you don't always know...

... Oi crap. I read it the other way around, fail's on me. Sorry! – Kablam May 16 '12 at 8:20 ...

...pointer bugs. If a dangling pointer is accessed after it is freed, you may read or overwrite random memory. If a null pointer is accessed, you get an immediate crash on most systems, telling you right away what the error is. For local variables, it may be a little bit pointless if it is "obvious" t...
