Coroutine vs Continuation vs Generator
... realising it. Exceptions, for instance, can be thought of as a kind of inside-out continuation. I'll give you a Python based pseudocode example of a continuation.
Say Python had a function called callcc(), and this function took two arguments, the first being a function, and the second being a lis...
How do HTML parses work if they're not using regexp?
... Iterating it yourself with lots of custom logic isn't such a great idea. Use a library that supports the standard algorithm if you can. e.g. search.cpan.org/~tobyink/HTML-HTML5-Parser-0.03/lib/HTML/HTML5/… / code.google.com/p/html5lib

How are Python's Built In Dictionaries Implemented?
...s a fail.
BTW, the dict will be resized if it is two-thirds full. This avoids slowing down lookups. (see dictobject.h:64-65)
NOTE: I did the research on Python Dict implementation in response to my own question about how multiple entries in a dict can have same hash values. I posted a slightly ed...
Why don't Java Generics support primitive types?
...primitive types to be used as parameter types for generics. But the flip side of doing this is that such languages' implementations of generics (or template types) typically entail generation of a distinct copy of the generic type for each type parameterization.

Difference between git checkout --track origin/branch and git checkout -b branch origin/branch

(That is, as commented by Sebastian Graf, if the local branch did not exist already.
If it did, you would need git checkout -B abranch origin/abranch)
Note: with Git 2.23 (Q3 2019), that would use the new command git switch:
git switch -c <branch> --track <remote>/<bra...
Why Func instead of Predicate?

Do use the new LINQ types Func<> and
Expression<> instead of custom

How do I set up DNS for an apex domain (no www) pointing to a Heroku app?
...ic solution is to not use them at all. As a fallback measure, some DNS providers offer to setup an HTTP redirect for you. In that case, set it up so that example.com is an HTTP redirect to www.example.com.
Some DNS providers have come forward with custom solutions that allow CNAME-like behavior on ...
Named regular expression group “(?Pregexp)”: what does “P” stand for?
... mine: I've always thought it stood for Python. That may sound pretty stupid -- what, P for Python?! -- but in my defense, I vaguely remembered this thread [emphasis mine]:
