Wave-particle duality is nonsensical. It certainly makes a lot less sense than "there is an as-yet unknown kind of medium that supports the propagation of waves".

Most number crunching is definitely functional; however, most programming (even in science) is about all the window dressing before you get to the actual heart of the number crunching. For those tasks, an imperative syntax is usually more

Um, free software was the way of the world before Bill Gates popularized the selling of the stuff. Stallman rose to the occasion as the defender of the "old way". He did not "invent" free software, whatever that means. (He did invent the

But if you look at the actual cutting edge research work in the HPC and scientific space, they are working on languages that allow domain experts to express computation using higher level primitives, not on fancy compiler techniques to make

Um, that's not a dumb measure of simplicity, it's just a measure of code size. You might as well look at the average number of characters in the names of the authors of the two projects; it would be equally irrelevant. Here is a real measu

"...they just lack a reasonable replacement for C" Actually, Fijal, I have a question - and this is related to our previous Skype discussion as well. I know that a lot of the work on PyPy has been on the JIT, but have you guys really ever

Yes; numexpr and weave are pretty reasonable solutions, although a little "weird" because they take opaque strings. One bit of context that is missing from this discussion (although Travis did allude to it earlier) is that we are actively w

I'm curious - what sorts of work do you do in the data warehousing space? Do you work as a consultant, or as an implementor at a customer of data warehouse products? It seems to me that that whole industry (DW & ETL) is a dinosaur whos
