Here's a question about blocks: should they even have return values? I was wondering about that because (1) they are supposed to have an equivalence with a code sequence and code sequences don't have values and (2) one awkward difference b

Thanks for the links. It's neat to see such things being considered. My feeling is that such complicated language devices are out of place in JavaScript but it was fun to run the experiment. While I'm thinking about it... I wonder about t

Hehe. That's quite a monster. I'll try to be a bit more helpful. 1. Use loop instead of dotimes so you can make the index range over 1-100 instead of 0-99. 2. Factor out the string calculation so you only need one print statement. 3. Mayb

Surely, the lispiest way is to write an interpreter! Write a function fizzbuzz-eval so that the following is a solution (left as an exercise). ;) (fizzbuzz-eval 100 '(((3 5) (print "FizzBuzz")) ((3) (print "Fizz"))

I like both of those solutions. The Haskell solution is almost the same as what I had come up with but I wasn't familiar with iterate, which makes it even nicer. So thanks for that. Looking at the C version, I wondered if it could be done

This kind of problem has really short solutions when you have access to collection-at-a-time operations. For example, in Haskell: pascal 1 = [1] pascal i = zipWith (+) ([0] ++ pascal (i - 1)) (pascal (i - 1) ++ [0]) I'm not an

I just skimmed through it and there's a really controversial claim in there that the functional paradigm was a bad idea! I also found it surprising that he disliked Dijkstra's display idea since I've used a variant of that to great effect.

For language enthusiasts with hobby compilers, the question does not have to be a hypothetical. :)

I haven't read much at all about Dart yet so forgive me if I'm missing something but it seems to me that dynamic-typing capabilities do not rule out absence-of-null. Doesn't Dart's use of optional typing mean that it really behaves as a sta

Sounds like the Ubiquitous Language idea from Domain Driven Design is a closer analogue. I haven't read Christopher Alexander's book so I'm just going on the article's summary. http://domaindrivendesign.org/node/132

Cool! This is something I wanted to have and had started making for myself. Mine is much less useful than asciiflow but the thing I like most about it is that it allows writing and drawing more in the way I use my notebook. It's easy to

I actually liked the earlier article better. But I think it's good to see the paths that have been taken to get to where we are today. Just because you have seen what the original LISP was like doesn't mean you are forever doomed to bel

Seems a lot like Go ( http://golang.org ). See http://golang.org/doc/effective_go.html#interfaces_and_types and http://golang.org/doc/effective_go.html#embedding .

What's so bad about C? It's not very pretty but the following was easy enough to write and worked first try. http://pastebin.com/QBAgzWWJ Pipe the result through "sort -u" if you don't want dups.

They want to protect the public from unsafe false copies? I can suggest this for software: educate the public on the use of simple cryptographic tools. The public needs to know how to check for themselves that their torrented copy is an

A good read on this topic: John Carmack's .plan entry from 14 Oct 1998. He writes about replay as a development tool, how it's necessary to record time, and how journaling inputs "turns a realtime application into a batch process".

Having skimmed the PicoLisp interpreter a long time ago, I remember it being like Emacs Lisp in that common performance-critical functions like mapcar were implemented in C. It seems like a very pragmatic way to get the performance you nee

If you are mathematically inclined, this might help. It's how I, as a non-musician, came to understand tuning a little. Equal temperament uses frequencies that are scaled by powers of the twelfth root of 2. Moving up one semitone is the s

Closures are different from objects in only a couple of ways: (1) the creation protocol is extremely concise (lambda) (2) the access interface is the function call Say that closures lower the syntactic overhead of accessing the same flexibi
