Worst of all is the use of "if (x) { return true; } else { return false; }". What an awful idiom to be teaching to people.

Considering that email addresses can contain nested comments, the authors were simply masochistic.

But really, use something like "does the string contain a @" as basic validation to make sure the user didn't mess up, then validate by actually sending mail.

Honestly, given the number of email validators I've come across that incorrectly tell me that my email is invalid because it's got a '+' in it, I'd much rather they stuck to something simple like that. This at least won't reject valid email addresses.

That was my point (badly expressed). .+@.+ is about the only regex you can use that won't generate false negatives. Another example of this fun is myname@1234567890. Of course root is a valid email address, so even the above creates false negatives, for given values of false.

Also can 1.2.3.4 be a valid domain name?

Although labels can contain any 8 bit values in octets that make up a
label, it is strongly recommended that labels follow the preferred
syntax described elsewhere in this memo, which is compatible with
existing host naming conventions. Name servers and resolvers must
compare labels in a case-insensitive manner (i.e., A=a), assuming ASCII
with zero parity. Non-alphabetic codes must match exactly.

0x07 (visual bell) is a valid domain name component. I wonder if any registrar will accept it...

I don't think amivalid@123.23.3 is direct delivery to an IP address. It's been a while since I read RFC822, but I seem to recall that you need to stick brackets around the IP address.

Yay for wikipedia!

quote:

Perl was originally named "Pearl," after the Parable of the Pearl from the Gospel of Matthew. Larry Wall wanted to give the language a short name with positive connotations; he claims that he considered (and rejected) every three- and four-letter word in the dictionary. He also considered naming it after his wife Gloria. Wall discovered the existing PEARL programming language before Perl's official release and changed the spelling of the name.

When referring to the language, the name is normally capitalized (Perl). When referring to the interpreter program itself, the name is often uncapitalized (perl) because Unix-like file systems are case-sensitive. Before the release of the first edition of Programming Perl, it was common to refer to the language as perl; Randal L. Schwartz, however, capitalised the language's name in the book to make it stand out better when typeset. This case distinction was subsequently documented as canonical.[10]

There is contention about the all-caps spelling "PERL," which the documentation declares incorrect[10] and which some core community members even consider a sign of outsiders.[11] Although the name is occasionally taken as an acronym for Practical Extraction and Report Language (which appears at the top of the documentation[12]), this expansion actually came after the name; several others have been suggested as equally canonical, including Wall's own humorous Pathologically Eclectic Rubbish Lister.[13] Indeed, Wall claims that the name was intended to inspire many different expansions.[14]

.....

It's awesome. We have our own "official" date object, that doesn't store date's before 1/1/1970.

Suppliers send us dates earlier than this all the time, and it just gets stripped from the XML.

A friend of mine has been asked to replace the calls to functions in System.Security.Cryptography in a C# app he's working on with calls to encryption functions written in-house in order to 'increase' security. Needless to say that the in-house encryption functions amount to nothing more than a polyalphabetic cipher with a fixed key.

Mmm, I love me some security.

check out this sweet container (DynamicArray is a homegrown resizable array that's basically std::vector without bounds checking and the added bonus of being completely inscrutable to the visual c++ debugger)

code:

class WallContainer {
private:
	DynamicArray <Wall> walls;

public:
	void AddWall (Wall wall) {
		walls.AddToEnd (wall);
	}

	int Size () {
		return walls.Size ();
	}

	Wall GetWall (int index) {
		return walls [index];
	}

	void SortWalls () {
		for (int i = 0; i < walls.Size () - 1; i++) {
			for (int j = i + 1; j < walls.Size (); j++) {
				Wall w1 = walls [i];
				Wall w2 = walls [j];
				if (w1.instNum > w2.instNum) {  
					Wall tmp;
					tmp = walls [j];			
					walls [j] = walls [i];
					walls [i] = tmp;
				}
			}
		}
	}

	double GetWallThicknessByInstNum (long instNum) {
		int max = walls.Size () - 1;
		int min = 0;

		for (int pos = (max + min) / 2; max >= min; pos = (max + min) / 2) {
			Wall w;
			w = walls [pos];
			if (w.instNum == instNum) {
				return w.wallThickness;
			}

			if (w.instNum < instNum) {
				min = pos + 1;
			} else {
				max = pos - 1;
			}
		}

		return 0.0;
	}
};

use: populate the container, call SortWalls, and then don't add any more walls. I'm not really sure what GetWall is supposed to be useful for.
