Build the full path filename in Python
...
If using a function anyway makes you feel better (and you like needlessly complicating your code), you can do this:
os.path.join(dir_name, '.'.join((base_filename, filename_suffix)))
If you prefer to keep your code clean, simply include the dot in the suffix:
suffix = '.pdf'
os.path.join(dir_name,...
How do I write a short literal in C++?
...en doing because I couldn't find anything about it. I would guess that the compiler would be smart enough to compile this as if it's a short literal (i.e. it wouldn't actually allocate an int and then cast it every time).
The following illustrates how much you should worry about this:
a = 2L;
b =...
How can I decompress a gzip stream with zlib?
...mat files (created with the gzip program, for example) use the "deflate" compression algorithm, which is the same compression algorithm as what zlib uses. However, when using zlib to inflate a gzip compressed file, the library returns a Z_DATA_ERROR .

How to return smart pointers (shared_ptr), by reference or by value?
... a increment-increment-decrement sequence or something like that in modern compilers. So the best way to return a shared_ptr is to simply return by value:
shared_ptr<T> Foo()
{
return shared_ptr<T>(/* acquire something */);
};
This is a dead-obvious RVO opportunity for modern C++ ...

What's the difference between hard and soft floating point numbers?
When I compile C code with my cross toolchain, the linker prints pages of warnings saying that my executable uses hard floats but my libc uses soft floats. What's the difference?

What does it mean for a data structure to be “intrusive”?
... that. When you put something into that data structure, that "something" becomes aware of the fact that it is in that data structure, in some way. Adding the element to the data structure changes the element.
For instance, you can build a non-intrusive binary tree, where each node have a reference ...
