At least MS gives you a choice. They do that because you can pick to 
download C++, C#, the IDE, and the SQL server, and it'll download just the 
parts you need without duplicating them. Plus it downloads the right version 
for your OS, etc.

Only 200? I think the Eclipse at work takes 550M to 600M to start up.

Try Eclipse. Try pasting a comment from one part of the file to the other 
making it go "unresponsive" long enough that Gnome asks if you want to kill it.

It's an attempt at improving Make without actually fixing the major problems 
with Make.

Wait until you get into the generics, where you do things like turn a list 
of Freds into an array of Freds by invoking

   fredList.toArray(new Fred[]{});

i.e., by passing an empty array of Freds to the function in order to pick 
the right generic to return. Yes, you actually put an empty array on the 
heap simply to pass compile-time type data to pick the right method in a 
language that supports generics. Because there's no syntax for
    fredList.toArray<Fred>();

> the program. VS did all of this and more. :-P

Over the weekend, I wrote a program to take a couple CSV files, munge them, 
and stick them into some XML I could pull into the tax authority's forms, in 
C#.   It was like surfacing from under quicksand to use VS instead of 
Eclipse. I hadn't realized just *how* much Eclipse kills me at work compared 
to something designed by CHI experts instead of hackers.

I have a big text file with all my Eclipse hates on my desktop, just keeping 
track for a good rant some day.

Yes, in spite of promising on day 1 that they'd never do that.

I'm pretty sure that's not true. What *is* true is that .NET DLLs load as 
shard DLLs, and java .class files can't do that, since they're data.

It's not only that, but it's also a whole plug-in mentality.

You go to the project explorer with the tree view of your project's classes. 
You double-click a class to open it. You type Ctrl-F and start typing the 
name of the method you're looking for. What do you think happens? If you 
answer "Well, the focus was left on the project explorer because Eclipse is 
so modular it doesn't know where to put the focus, so your search string is 
in the wrong window", give yourself a cigar. If you continued "... and so 
you now have to click *three times* in the class window to change focus, 
once to close the search box in the project window, once to put the focus in 
the class window, and once to put it in the edit pane of the class window, 
and *now* you can type Ctrl-F", you may light your cigar.

Indeed. Or use an IDE by a group that actually has a CHI/UI expert on board.

1. Micro-benchmarks are one thing. Large applications are another.

2. It seems the fastest is actually Fortran. (?!) Followed by C++. 
Followed by C. Followed by ATS and ADA. Only then do we get to Java, at 
70% slower.

(Mind you, Haskell is sitting there at 180% slower, so...)

No, I'm pretty sure that's not correct.

The .NET libraries probably show up as shared RAM rather than private 
RAM, but they do still show up.

Alrighty then.

Easy.

A Haskell programmer not thinking about types is like an assembly 
programmer not thinking about processor registers. It is nonsensical.

Quite. I'm still waiting on the "who the hell writes code like this

Ah yes. The great language shootout. An elaborate benchmark for

language. ;-)

Well, given that Java 1.0 dates to 1995, nobody would be arguing about 
Java back in the 60s. :-P

Hint: When anybody says "Apache", they almost always mean "the Apache 
web server". Few people seem to realise that the Apache foundation even 
/make/ anything else. That's how popular their other stuff is.

It is also news to me that Perl has gone anywhere but up. :-P

Um, no. If your source file contains any tab characters, the compiler 
spits out an error message and refuses to compile it.

OK. So turn off the layout rule. :-P

I've heard of them - but I have no idea what the hell they are. Last 
time I checked, "enterprise" refers either to NCC-1701-D, a galaxy-class 
starship of the United Federation of Planets, or to a piece of software 
which is pointlessly over-engineered, over-complex, over-priced, and 
sold by pushy over-paid salesmen in bad suits.

I thought I would hate it... but when not used in insane ways, it 
actually works quite well. I mean, most programmers indent stuff 
sensibly /anyway/, so having it be significant just means that you can 
avoid having to type a few extra delimiters.

...except in those handful of cases where how /you/ want to indent 
doesn't match what the compiler wants. /Then/ it becomes annoying.

Sure. Several companies are using GHC to produce mission-critical (and 
often security-critical or even safety-critical) production code.

You know, I spent an entire semester studying "human-computer 
interaction" without once comprehending WTF the subject was supposed to 
be about. Perhaps if they'd made us use NetBeans and then compile a list 
of all the things that are wrong with it, /then/ we would have understood...

Although... Zimin Wu /did/ look like he was actually a stage magician. I 
kept expecting him to be like "and, arh, here we have arh typocarh 
usarh, and arh, here we have A FLOWER!" and rip a big bunch of paper 
flowers out of his sleeve. But, weirdly, he never actually did this...

Usually if you hunt around the MS site, you can find the "network 
administrator" download, "for IT professionals", which /actually/ 
downloads enough data for offline installation. Because, let's face it, 
only an IT professional would have the technical skill to know that 
there's a difference between downloading an installer and downloading a 
downloader for an installer... oh, wait.

Oh, that's cute. No wonder I hear nothing but good things about 
Eclipse... I gather there's even a Haskell plugin for it. (I bit it 
doesn't /do/ anything though.)

Well, they fixed /one/ major problem: Text processing tools which turn 
tabs into spaces. ;-)

> Wait until you get into the generics

Uh, yeah.

It seems either they implemented everything twice (once with, and once 
without generics), or it's actually legal to not specify type parameters 
and then they default to Object. Which, either way, is highly 
counter-intuitive...

I don't know about CHI experts - more like unpaid beta testers. ;-)

And by "rant" you of course mean "shotgun rampage"? ;-)

Ah, but did they formally deprecate it, or just "strongly encourage you 
not to use it"? ;-)

Is it wrong that whenever I read a sentence like this, I can hear a

Every time I hear somebody say this, a part of me wants to scream "you

Writing the entire program in one source file on a single 435,235,342 
character line is "syntactically correct". But no sane programmer would 
ever do such a horrifying thing. :-P

Oh yes. I don't remember the names exactly, but I can clearly remember 
how one release of Java had BufferedInputStream and friends. And then in 
the next release, they deprecated that and gave you BufferedReader 
instead. And then in the next release, they deprecated BufferedReader 
and UNdeprecated BufferedInputStream again. (Pro tip: You should /never/ 
need to UNdeprecate something!)

Of course, when I was using Java, it was still quite new. I'd be 
interested to know whether the libraries eventually settled down and 
they stopped doing crap like this, or... ?

Hahaha. "That special OSS air". Yep, NetBeans has that. I don't know 
whether it's the cute but poorly-drawn icons that seem bigger than 
necessary. Or the slightly odd grouping of user preferences. Or the way 
that different parts of the IDE contradict each other as to the current 
status of the code, because each part is out of date by a different 
amount...

I don't know about "what helps software developers to be productive"... 
How about "what makes software developers buy our product rather than 
somebody else's"? Or even "what makes software developers develop for 
our platform rather than somebody else's"? ;-)

The entire MS business model fundamentally depends on getting everyone 
to use the MS platform, and then be locked in. Well, if your platform 
has naff-all software for it, nobody will buy it. But if your platform 
has all the best stuff, people will pay. And then be trapped. So it pays 
(literally) to make it easy for people to write code for your platform 
and only your platform. >:-D
