Toward a better programming
I alternate between thinking that programming has improved tremendously in the past 30 years, and thinking that programming has gone nowhere.<p>On the positive side, things that were cutting-edge hard problems in the 80s are now homework assignments or fun side projects. For instance, write a ray tracer, a spreadsheet, Tetris, or an interactive GUI.<p>On the negative side, there seems to be a huge amount of stagnation in programming languages and environments. People are still typing the same Unix commands into 25x80 terminal windows. People are still using vi to edit programs as sequential lines of text in files using languages from the 80s (C++) or 90s (Java). If you look at programming the Eniac with patch cords, we're obviously a huge leap beyond that. But if you look at programming in Fortran, what we do now isn't much more advanced. You'd think that given the insane increases in hardware performance from Moore's law, that programming should be a lot more advanced.<p>Thinking of Paul Graham's essay "What you can't say", if someone came from the future I expect they would find our current programming practices ridiculous. That essay focuses on things people don't say because of conformity and moral forces. But I think just as big an issue is things people don't say because they literally can't say them - the vocabulary and ideas don't exist. That's my problem - I can see something is very wrong with programming, but I don't know how to explain it.
