What is the combinatory logic equivalent of intuitionistic type theory?
...------------ S ={beta} T
G |- x : S G |- s : T
In a small variation from the original, I've made lambda the only binding operator, so the second argument of Pi should be a function computing the way the return type depends on the input. By convention (e.g. in Agda, but sadly not...
What is the difference between a framework and a library?
...
Actually these terms can mean a lot of different things depending the context they are used.
For example, on Mac OS X frameworks are just libraries, packed into a bundle. Within the bundle you will find an actual dynamic librar...
Determine function name from within that function (without using traceback)
... Combining @CamHart's approach with @Yuval's avoids "hidden" and potentially deprecated methods in @RoshOxymoron's answer as well as numerical indexing into the stack for @neuro/@AndreasJung's answer: print(inspect.currentframe().f_code.co_name)

How do I choose grid and block dimensions for CUDA kernels?
...eads per block should be a round multiple of the warp size, which is 32 on all current hardware.
Each streaming multiprocessor unit on the GPU must have enough active warps to sufficiently hide all of the different memory and instruction pipeline latency of the architecture and achieve maximum throu...
Principles for Modeling CouchDB Documents
...or instance). Managing the relationships or connections between various, smaller documents can be confusing at first, but CouchDB provides several options for combining disparate pieces into single responses.
The first big one is view collation. When you emit key/value pairs into the results of a m...
What is private bytes, virtual bytes, working set?
...se values are a reliable indicator of how much memory an executable is actually using, and none of them are really appropriate for debugging a memory leak.

There's a simple iterator protocol that can be applied to any kind of object to make the for loop work on it.
Simply implement an iterator that defines a next() method, and implement an __iter__ method on a c...
