How to reliably guess the encoding between MacRoman, CP1252, Latin1, UTF-8, and ASCII
...n bother with them, or ISO-8859-1, just detect windows-1252 instead.
That now leaves you with only one question.
How do you distinguish MacRoman from cp1252?
This is a lot trickier.
Undefined characters
The bytes 0x81, 0x8D, 0x8F, 0x90, 0x9D are not used in windows-1252. If they occur, then as...
What is the difference between a framework and a library?
...k" for that. In some way he rather explains how the term framework is used nowadays. It's just a hyped word, as I said before. Some companies release just a normal library (in any sense of a classical library) and call it a "framework" because it sounds more fancy.

When do Java generics require
... a match that the compiler works out to Matcher<ArrayList<T>>. Now if it wasn't a type parameter, things would be fine, because List and ArrayList are covariant, but since Generics, as far as the compiler is concerned require ArrayList, it can't tolerate a List for reasons that I hope ar...

What do people find difficult about C pointers? [closed]
...or how much room the compiler gives for a particular chunk of memory. You know you're dealing with this problem when people talk about "what (primitive) variable X really is".
Most of my students were able to understand a simplified drawing of a chunk of memory, generally the local variables secti...
Determine Whether Two Date Ranges Overlap
...other,
nor completely before the other,
then they must overlap.)
Now one of De Morgan's laws says that:
Not (A Or B) <=> Not A And Not B
Which translates to: (StartA <= EndB) and (EndA >= StartB)
NOTE: This includes conditions where the edges overlap exactly. If you ...

I know it's an old topic, but in c# 7 you can do :
switch(shape)

case Circle c:
WriteLine($"circle with radius {c.Radius}");
break;
case Rectangle s when (s.Length == s.Height):
WriteLine($"{s...
What exactly is a C pointer if not a memory address?
...s perfectly legal per the language standard so long as the implementation knows how to transform those numbers into addresses and how to do pointer arithmetic with those numbers and all other things required by the standard.
