++ FALSE DICHOTOMY! Will they never learn? When you find and fix a performance problem, the code is not only quicker, it's better. I only regret that I have but one upvote to give!

++ If I could expand on the chair - you need to sit upright, have good lumbar support, have your keyboard / mouse down low, and your monitor up high so you are looking straight at it. The chair should support your forearms and not your elbows. Ideally it should give good ventilation to carry away perspiration.

comment Why hasn't a faster, “better” language than C come out?
@Pestilence: I've heard that, but I haven't seen it. I've seen plenty of C and Fortran, including lately. I haven't seen any case where the ASM that Fortran generates could not be equaled by C in the hands of a competent programmer. Maybe it exists, but I haven't seen it.

I think the idea that Fortran is faster than C is somewhat myth, depending on what's being coded and who's doing it. The reason heavyweight numeric libraries are in Fortran is not because Fortran is faster, but because the routines were originally coded in Fortran and few people have the nerve or need to re-write it. The small number of math-gurus who write and vet these algorithms are happy in Fortran and see no need to change, especially since they imagine Fortran is faster.

... and the idea that performance works against maintainability is also another common idea that many people believe, but isn't necessarily so. This field has a lot of those beliefs.

... I know it's counterintuitive, but that's my experience. The link I gave above is a pretty good small example of how by tuning a "pretty good" program you can make it both faster and smaller, and learn from the experience.

@Jim: Certainly you want to avoid the premature optimization part, because that is another form of guessing. What I've found, though, is if you take a big program, and do performance tuning on it, you find out that what makes it slow is also what makes it big. That experience leads to designing things better in the future, so they are simpler, faster, and smaller. But without the tuning experience, you don't learn that lesson.

... and it's not only the time you spend writing the email, but the time it takes to get your head back into the code from where you left off. For me, that's the daunting part.

comment When is it reasonable to create my own programming language?
@Dog: From an AI viewpoint, that would be ideal. Take a look at differential execution. That's a real example of cutting the source code by an order of magnitude. Boilerplate may be necessary, but it's not a good thing.

And, have all the failure responses thoroughly planned, on the conviction that they will be needed.
