List of lists changes reflected across sublists unexpectedly
...nt list [[1] * 4] evaluates to, not the [[1] * 4 expression text. * has no idea how to make copies of that element, no idea how to reevaluate [[1] * 4], and no idea you even want copies, and in general, there might not even be a way to copy the element.
The only option * has is to make new referenc...
Hidden features of Scala
...gher-kinded types)
Without this feature you can, for example, express the idea of mapping a function over a list to return another list, or mapping a function over a tree to return another tree. But you can't express this idea generally without higher kinds.
With higher kinds, you can capture the ...
How to clear/remove observable bindings in Knockout.js?
...
Isn't the idea of KO that you should very rarely be touching the dom yourself? This answer loops through the dom , and would certainly be far from unusable in my use case.

How to generate a random int in C?
...
+1 for simplicity, but it is probably a good idea to emphasize that srand() should only be called once. Also, in a threaded application, you might want to make sure that the generator's state is stored per thread, and seed the generator once for each thread.

Check if a string is html or not
...) {
if (c[i].nodeType == 1) return true;
}
return false;

I made a couple of tests and looks like it works:
isHTML('<a&g...
Return all enumerables with yield return at once; without looping through
...ollection must be created per call, returning a collection is a really bad idea.
Most collections can be modified when returned.
The collection is of finite size.
Sequences
Can be enumerated - and that is pretty much all we can say for sure.
A returned sequence itself cannot be modified.

Can I make a user-specific gitignore file?
...
For example, you want ignore ~/some/path/.idea folder:
# 1. Add .idea to user specific gitignore file
echo .idea > ~/.gitignore
# 2. Add gitignore file to gitconfig
git config --global core.excludesfile ~/.gitignore

What's the need of array with zero elements?
...
The idea is to allow for a variable-sized array at the end of the struct. Presumably, bts_action is some data packet with a fixed-size header (the type and size fields), and variable-size data member. By declaring it as a 0-len...
Can I list-initialize a vector of move-only type?
...gt; idiom described on cpptruths (cpptruths.blogspot.com/2013/09/…). The idea is to determine lvalue/rvalue at run-time and then call move or copy-construction. in<T> will detect rvalue/lvalue even though the standard interface provided by initializer_list is const reference.
