Large-scale design in Haskell? [closed]
...programs like system daemons in Haskell.
In the end, you live in a monad transformer stack. At the bottom is IO. Above that, every major module (in the abstract sense, not the module-in-a-file sense) maps its necessary state into a layer in that stack. So if you have your database connection co...
What are the differences between Perl, Python, AWK and sed? [closed]
...e as Perl.
OK - when to use each?
Sed - when you need to do simple text transforms on files.
Awk - when you only need simple formatting and summarisation or transformation of data.
Perl - for almost any task, but especially when the task needs complex regular expressions.
Python - for the same ta...

Simple explanation of MapReduce?
...the way down to the basics for Map and Reduce.
Map is a function which "transforms" items in some kind of list to another kind of item and put them back in the same kind of list.
suppose I have a list of numbers: [1,2,3] and I want to double every number, in this case, the function to "double ev...

Force DOM redraw/refresh on Chrome/Mac
...eZ fixed the issue without needing extra javascript.
.willnotrender {
transform: translateZ(0);
}
As these painting issues show up mostly in Webkit/Blink, and this fix mostly targets Webkit/Blink, it's preferable in some cases. Especially since many JavaScript solutions cause a reflow and r...
What are free monads?
...d homomorphisms to a category of endofunctors where the arrows are natural transformations, and we look for a functor that is left adjoint to that.
So, how does this relate to the notion of a free monad as it is usually used?
Knowing that something is a free monad, Free f, tells you that giving a...
Mapping over values in a python dictionary
...ctionary can be used to store the original data as if it was a dict, while transforming any data on request with a callback.
Of course, feel free to name the class and the function the way you want (the name chosen in this answer is inspired by PHP's array_walk() function).
Note: Neither the try-e...
