How does the Java 'for each' loop work?
...
This answer is now a blog post and was created from two related answers that I've written: here and here. It also includes a generically useful class for comparing the speed of two functions (at the bottom).

Does using “new” on a struct allocate it on the heap or stack?
...ocation.
Thirdly, I'm ignoring generics, mostly because I don't actually know the answer, and partly because it would complicate things too much.
Finally, all of this is just with the current implementation. The C# spec doesn't specify much of this - it's effectively an implementation detail. Ther...
Why does the arrow (->) operator in C exist?
...o an int value positioned at byte-offset 2 in the continuous memory block known as c, even though type struct T had no field named b. The compiler would not care about the actual type of c at all. All it cared about is that c was an lvalue: some sort of writable memory block.
Now note that if you ...
Haskell: Lists, Arrays, Vectors, Sequences
..." (putting objects at the end) than any pure linked list data structure I know of, although this is not a persistant data structure so less friendly than Haskell's lists.
The third problem with lists is that they have poor space efficiency. Bunches of extra pointers push up your storage (by a cons...
Why does jQuery or a DOM method such as getElementById not find the element?

It's now 2020 — is "Placing scripts at the bottom" still "considered a best practice" ? I (nowdays) put all my resources in the <head> and use defer on scripts (I don't have to support bad-old incompatible browsers)

How to find time complexity of an algorithm
...y 2.
For this reason, we drop all but the largest terms for large N.
So, now we have gone from 2N + 2 to 2N.
Traditionally, we are only interested in performance up to constant factors.
This means that we don't really care if there is some constant multiple of difference in performance when N i...
Difference between author and committer in Git?
...author the "person who wrote the code" doesn't make sense. How would git know who wrote it? When you set git config user and then git add and git commit, then git would know who added and who committed, but it still would not know who wrote it.

What's the point of having pointers in Go?
I know that pointers in Go allow mutation of a function's arguments, but wouldn't it have been simpler if they adopted just references (with appropriate const or mutable qualifiers). Now we have pointers and for some built-in types like maps and channels implicit pass by reference.

Can you explain the concept of streams?
...ata, just like water continuously flows in a river. You don't necessarily know where the data is coming from, and most often you don't need to; be it from a file, a socket, or any other source, it doesn't (shouldn't) really matter. This is very similar to receiving a stream of water, whereby you don...
