   shell + shell tools + piping = a league of its own. As a big fan and advocate of a low level language (C) and a high level language (Python), as a combo, being a very powerful paradigm, I still can't believe some of the things the, sha

   Unless your new classical mechanics predicts the outcome of an experiment that other existing theories cannot predict, and that prediction turns out to be true if such an experiment is conducted, your new idea is just another hypothesis. Fu

   For me it was a bit the other way around. I solved the problem in a brute force way and on interviewer's asking, was flopping to come up with a better algorithm. Then he mentioned that I should consider DP. Unfortunately my DP was real

    Good for that guy but by 'Antarctic expedition' I was expecting something different. I'm a lot more interested in going to Antarctica, spend a few months there as part of some scientific research team. Or maybe just go there

    It's two separate things, both mentioned in your question: simulation then animation. Both steps are computationally expensive enough that they can't be done in one run. For simulation, typically a molecular dynamics code is used

    I hadn't thought of coupling, the distributed nature, so you have a point. However we can think of splitting up the system into pieces, and try to localize the update. For example, for a worldwide distributed system keep everything els

    I agree. But that also means the major roadblocks are sociopolitical and not technical (not saying technical challenge is not there, just that it's not the biggest issue).

    But it runs, and it shows stuff on screen, and it saves stuff in the hard-drive! I'm not saying I'll do things the conventional way. Once you give up the conventional way, it becomes a different ball-game.

    Programming in the debugger is a massively overlooked paradigm. We use gdb for interactive usage. You could become a super-productive programmer if you can use gdb programmatically. The possibilities are endless. The problem: gdb developers

    I'm afraid a very important point was missed. What is it that's being programmed? Commodore 64 programmers were never interested in "Bayesian Statistics" and "Digital Signal Processing". Their main interest was
