In Topic: TV Show cipher

The note in the margin shows the substitutions for the first three letters, hence it is a substitution cipher. But you realise that most hacking/cryptography/security/technology isn't real in movies, let alone in tv shows?

Nice idea. You could make it more robust by using a naive Bayes Classifier instead of simply searching for words (JS library). And you can use it to infer more than just moods, although I don't know at what point it turns from a funny app into a creepy information gathering one

If I would tell them that spending 10 minutes reading this could save more than 50 new upgrades with simple code improvements that account for a 50x+ performance increase, do you think they would listen?

Most (if not all) of those optimisations fall prey to the false logic that a 50x micro optimisation leads to a 50x performance improvement across the application.

Apart from the first one, all of the optimisations have speeds in the order of microseconds or nanoseconds for the "slow version". Unless they are in some double for loop, the difference will be negligible compared to slower operations such as DOM access (for example: innerHTML is several orders of magnitude slower).

int i;
for (i = 0; i < fileSize; i++) {
	printf("%c", contents[i]);
}

instead of

printf("%s", contents);
