Ah, the fast pace of modern life :)

Likewise, a whole generation of office workers longs for the days of snail
mail instead of e-mail, so that we would actually be allowed some *time* to
do our work :)

Well, this one:

[url]http://www.manageability.org/blog/archive/20030520%23p_the_problem_with_cameron[/u
rl]

is the first one that comes up, but obviously something has gone wrong.  A
factor of 7700 speed difference?  They're just not measuring the same thing.
If C# were 7700 times slower than Java, it would be unusable.

I'm going to explore this and see what I can find out.  A quick test shows
that his C# program is indeed woefully slow.

Quick preliminary answer:  Both of the programs measure the time taken to
*compile* a regex, not the time taken to run it.  The two compilers are
probably doing very different things.

It's like dude went very far out of the way to find some bizarre
benchmark to suit his goal.  Who uses compiled regexs in c#
applications?

Those guys are called COBOL programmers, and they make the big bucks
:)

I do, in a tokenizer -- I compile a handful of them and then use each of
them thousands of times.  Nobody compiles a million different regexes and
uses each of them only once.

Give me IntelliJ or Eclipse any day.

And what do you feel are their advantages over Visual Studio?

Ehm, the main thing about Java is that it tries to keep out feature
creep. So what I'm missing in C# is any constraint to keep features out.

It's starting to look as another D language, in which you can do
anything. That's fine if you are a single programmer that does not care
about reuse or refactoring, but it's madness for enterprise code.

That you still have to take care to make things "virtual" is another
thing I'm really missing.

In other words: KISS (keep it Simple, stupid) is missing.

That's not to say that C# does not have a lot of things going for it,
some features are very useful, like checked code fragments (which, of
course, should have been the default, just like the virtual keyword).
