There are no "simple" bugs.

"Program testing can be a very effective way to show the presence of bugs, but is hopelessly inadequate for showing their absence." - Edsger Dijkstra

If the code and the comments disagree, they are both probably wrong

Inside every complex program is a simple program trying to get out

In theory, theory and practice are the same. In practice, they're not.

"There are no significant bugs in our released software that any significant number of users want fixed." - Bill Gates

First, make it work. Then, make it fast.

"Test doubles are objects that replace real dependencies to enable automated testing. They are the automated testing equivalent of movie stunt people: they take the place of the original since having the real one is expensive or impractical." Excellent analogy by @venkat_s

In JavaScript, a function always returns a value. If the return value is not specified, then it returns undefined.

"Part of the inhumanity of the computer is that, once it is competently programmed and working smoothly, it is completely honest." - Isaac Asimov

ssh 101 - ssh stands for secure shell and is used to securely connect to remote hosts - ssh creates a TCP connection on port 22 - Syntax: ssh username@hostname (or ip address)

"Simplicity is the ultimate sophistication." - Leonardo da Vinci

"I do not fear computers. I fear the lack of them." - Isaac Asimov

"Measuring programming progress by lines of code is like measuring aircraft building progress by weight." - Bill Gates

"Syntactic sugar causes cancer of the semicolon." - Alan J. Perlis

Deleted code is debugged code

"Owning a computer without programming is like having a kitchen and using only the microwave oven." - Charles Petzold

The difference between theory and practice is smaller in theory than in practice

The more bizarre the behavior, the more stupid the mistake.

There is nothing as permanent as a quick fix
