Why would you be annoyed at this? It's not a dominant perspective, one that you hear every day. Your statement, while pithy, misses the point.

It's funny, just today I finished up some work merging a hygienic expander into the core of Guile. I've been writing defmacros for a few years now, and while things are not all lovely in the world of syntax-rules or syntax-case, it is so mu

My colleague Jao, an ex-Googler himself, burst out laughing today when he heard about this. But it wasn't about the contents -- it was because El País, the most prominent newspaper of Spain, reported that Google is using a /logarithm/ to de

It works great for me, when I'm not breaking Guile all the time that is ;-) Seriously. Until Geiser, I didn't really know what having an active program text was like. Sure they've existed in the past. But still, it's really nice to feel lik

I feel compelled to mention that you could just use a language with a proper numeric tower. If the numbers that you input to an algorithm are exact, you get an exact answer. If they are inexact, you get an inexact answer. 399 999 999 999 99

A sane thing to do would be to keep the commit log, but only the changes to the subtree in question. However, though I am not a bad sh programmer, at some point my brain turned off reading that code.

I enjoy a good C++ snark from time to time.

I seem to recall from the Chubby lock paper the statement: "we have found Paxos behind everything". Of course they expressed it more eloquently. I think the Paxos papers are among the most beautiful in computer science.

I sympathize with the sentiment, but C's and C++'s lack of a memory model is really a barrier (ahem) to GC development. It's amazing that the BDW GC works as well as it does. I hack on Guile, and we're actually switching to use it.

That is not the issue at hand. The issue is conservative scanning of the stack.

I don't know why I clicked, but I'm glad I did. The points about "governance" emerging as an accident, a mistake even, were particularly perspicacious.

The thing is, usually when you want the stack frames, /they are there/. They're present because they form part of the continuation of the computation. Tail calls, because they don't form part of the continuation, are usually not interesting

The "Lambda: The Ultimate GOTO" paper shows a still-timely example of when you might want to express a state machine as mutually recursive functions. Granted, they compare to the actual GOTO, but you can't make state machines of any managea

Lynch mobs do not have electronic equivalents. The worst I can think of would affect a person's psyche, but Amazon is not a person. The analogy is not apt.

I have this too. I find it disturbing.

You don't have to name it. It could be _. (let (x . _) '(a b c) x) It sounds like you're treating list destructuring like CL's mvbind. While it's subjective of course, I'm more comfortable with the runtime doing what I mean when I

Unfortunately, this is not true in the case of type punning. C used to be the language you used when you wanted to access bits. Now with C99 you cannot * (int16* )((int32* )x). NB, all compilers make exceptions for unions, but the type punn

Old or not, it's still quite disturbing.

Cool stuff! But this sentence makes me cringe: "Liskov [...] was recognized for helping make software more reliable, consistent and resistant to errors and hacking ." (emphasis mine) From MIT, of all places!

Agreed. Here in Barcelona we have the ignomious fate of Bicing (bicing.com) being run by /ClearChannel/, of all organizations. Jeez.

That's the point, it's not a hash table -- it's an association list. People don't just use them because they're easier to write, they have nice functional characteristics. (Yes, hash tables are better for many things. I liked the #{} hack,
