comment Business case for decentralized version control systems
A centralized server failure wouldn't take down all your code. Even if you didn't have backups, the worst it could do is take down your revision history. But as long as all the developers have the code checked out, it exists in current form on their systems too.

comment Dealing with a fundamental design flaw when you're new to the project
@Matt: Then phrase it as "I don't know I'm right," and try your best to avoid making it sound sarcastic or accusatory.

comment What do you wish language designers paid attention to?
You ought to use Pascal. You can define a type that covers an arbitrary range of numbers, such as -5..25, which the compiler can verify at compile-time. (As long as you're only assigning constants, of course.)

comment “Software features that can't be demonstrated by automated tests simply don't exist”— Is it too extreme a statement?
@S.Lott: It starts out talking about proofs, but later on it gets into tests and user experience, which is more than just visual/GUI stuff. The point is that the stuff that really matters, that makes the users really care about a product and think it's well-made, tends to be precisely the stuff that "can't be demonstrated by automated tests."

comment Delphi doesn't have Lambda Expressions and I'm a Delphi programmer, what am I missing out on?
@Larry: Yeah, so you have to go and rewrite it as a normal method. I guess my objection is that I just tend to view "terse" code in general as a form of premature (and improper) optimization. It's optimizing for writing time at the expense of maintainability, which has been shown over and over again to comprise a far more significant piece of developing a program than the initial writing.

comment Delphi doesn't have Lambda Expressions and I'm a Delphi programmer, what am I missing out on?
@Larry: That's just fine in principle. Makes a lot of sense when you originally write it. But what happens over the next few months when what you need your tiny, simple little filter to do becomes more complicated?

comment Do you keep your ideas secret? and why?
@Matthieu: You seem to have posted that as a joke, but the movie makes a very good point.

comment Delphi doesn't have Lambda Expressions and I'm a Delphi programmer, what am I missing out on?
@Oscar: They're objectively hard to read because they provide less useful information than a normal function. Specifically, there's no function header with parameter types. In a strongly-typed language, that's important. It isn't apparent in trivial examples like Jader's demo, but when you start passing objects instead of numbers, especially if you use more than one argument, things can get very cryptic very quickly.

The 900% more code he mentions is also a severe exaggeration. While I agree that anonymous methods in Delphi could use some syntactic reduction, they're really not all that bad, especially for the amount of information they provide to the reader.

@Larry: Lambdas in general. Delphi doesn't have lambdas as such, but it has anonymous methods which are functionally the exact same thing, as Jader points out.

comment What do you wish language designers paid attention to?
Sorry, but I've gotta give you a -1 for being completely wrong on this. Terseness helps to write code faster, but it most definitely does not make code more readable, beyond a certain minimum. A certain level of verbosity makes code much easier to read, because those extra words and symbols mean something and impart meaningful information to the programmer, especially if it was originally written by someone else and you don't have the advantage of already having a mental model of it in your head.

comment What do you wish language designers paid attention to?
If explicit is better than implicit then why aren't you required to declare variables? When a simple typo can cause hard-to-debug errors, (as opposed to errors that are caught at compile time or runtime errors that are obvious and easy to debug,) that's a major strike against the language IMO.

comment Aggressive Auto-Updating?
Mostly. One thing Windows Update gets very, very wrong--to the point that I wouldn't be surprised to hear of it provoking a class action lawsuit--is rebooting your system without the user's explicit permission. No software should ever do that under any circumstances, especially on a multitasking machine where the possibility for lost work exists.

+1 for useful principles, -1 for making it all about money.

comment What are the common revenue models for free-software companies?
I've always wondered about this model. Logically, in order to make selling support for price-free software profitable, your software has to require enough paid support that you'd end up recouping your development costs plus extra. Wouldn't that make it the sort of software no one would want to use?

@Walter: Copying is not theft, and it's highly disingenuous and intellectually dishonest to claim that the two are equivalent.

comment Why do good programmers have ugly websites?
@Michael: I tend to take anything Paul Graham says with a grain of salt, since so much of it is demonstrably false and occasionally harmful. The only thing in that article that really struck me as having merit was at the end when he talked about empathy. That is something every developer should understand, and he states it quite well. But IMO the rest is just him being pretentious.

comment Why do good programmers have ugly websites?
I didn't say "creative". I said "aesthetic." They're two very different concepts. If I make a mistake, that's one thing, but please don't downvote me on the basis of something I didn't actually say.

comment Why don't browsers have the ability to differentiate between events triggered via input devices and scripts ex: element.onEvent()?
@Babiker: Not really. What's to stop that from being put into an automated script?

Hey, Wouter! Good to see you here on Programmers.
