How does that whole "pipe entire objects back and forth" thing work? I mean it seems that there must be some huge machinery to facilitate that kind of thing. For example, if I pipe object from my program to another, how does the other progr

That looks like a nice solution. I wonder what the question was.

If that were the case, the set of programmers who use C++ should be much smaller than it is currently. To me, this article describes yet another reason to not even try learning C++.

I would say "outside".

Yeah. I think I would personally go for two fields -- first name and last name -- with a hint that 'if unsure, use lastname' so that the rather common(?) 'sort by lastname' would make at least some sense in most cases, and the requirement t

Well, as far as I can tell, you are screwed anyway you do it, so you might as well do the simplest thing.

Huh, isn't it obvious? Accept anything as a name.

They should name the filter "Cockblock".

About packages and namespaces: Package is essentially a collection that maps symbols to values. In CL packages have (at least) two namespaces: one for functions, other for any kind of variables. The reason for this is that when you write th

Finding a method definition is quite easy in CL: just use the function 'find-method': http://www.cs.cmu.edu/Groups/AI/html/hyperspec/HyperSpec/Bod... Though grep would probably do just fine too, since method definitions are defined with '

Lisp-1 vs Lisp-2 is about whether functions and other variables are in the same namespace or not. Packages are orthogonal to this. Also, generic functions in Common Lisp don't suffer from nearly the same amount of complexity as can be found

So, one signal per minute?

> syntax modification Hmm, have I missed something? What features are you talking about?

It isn't, and people who say so probably don't know Lisp very well.

To me as a Lisp user, Python breaks more than it fixes. Lexical scoping? Nope, can't have it. Code as data, data as code? Not really. Literals for data? Compilation to native code? Compiler/interpreter warnings? Warnings for name collisions

Am I supposed to take article with that title seriously when it starts with: > PC vs. Mac Under what reasonable definition is a Macintosh not a personal computer?

The definition of Comparator-interface includes only two methods, .compare and .equals. The documentations says that it is always safe to not override .equals, so we're left with just .compare. This effectively means that each comparator is

Maybe it's just that I'm not a native English speaker, but this title seems very misleading to me. Though the BBC's title isn't much better.

Yeah, but that just seems wrong . It's like "I have this function, but I can't actually refer to it, so I'll have to wrap it in this thingamajig just so that I can pass it around".

Recently I was reading a debate about biking helmets (don't remember which kind of biking), and someone said something along the lines of "when you ride without a helmet, you are taking your life in to your own hands". I wonder whose hands

You can implement type inference and lazy computations in standard Common Lisp. You can't implement macros or proper runtime redefinition of functions in standard Haskell.

I for one don't understand why it needs both? Wouldn't it be a lot simpler to use only one or the other?

I have a feeling you might enjoy Common Lisp + Emacs + Slime.

Sometimes I wonder whether I should really try Ruby, but brainfarts like these always remind me why I decided against it the last time.

Another problem is that the "acceleration" slot actually describes the opposite of what one would think.

I just died a little inside. Knowing that there are people out there that would inflict this kind of nonsense as a standard for others to use makes one really lose faith in humanity.
