Relax. You will make all the mistakes because the laws don't make sense until you trip over them :)

Comment your code? Yep. Helped me ten years later working on the same codebase.

You can't read a book about best practises and then apply them as if wisdom is something you can be told :)

It is like telling kids, "If you do this you will hurt yourself" YMMV but it won't :)

Wipe if you think you can do better :) It can and has been done.

Problem solved.

(I am joking!)

We didn't learn APL (Who is teaching the use of those custom keyboards to 100s of young students for one semester?)

The processing power of systems at the time made it clear which language classes were practically useful and usable for the time and which were not.

Prolog ran like a dog for even simple sets of logic.

We had the best internet access and pretty powerful desktop systems for the time.

I'm still curious why we didn't learn smalltalk. Could have been the difficulty of submitting and marking a system in a particular state rather than a file of code :)

Pausing a game has a massive impact on the game experience. It lets you break the fourth wall experientially. Not wrong, but it changes the dynamic of the game.

Same as saving at any time does. As losing your loot or your life permanently does. Not wrong, but a hard choice that appeals to some players and not to others.

I used to pause pacman on my Atari 800 so I could run to church and sing in the choir or be an altar boy. Then I ran home and unpaused to continue. Sometimes in summer the computer over-heated and I lost everything while I was at church.

Lessons learnt? None, I think :)
