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

Deleted code is debugged code

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

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

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

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

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)

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

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

"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

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

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

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

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

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

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

There are no "simple" bugs.

"The only constructive theory connecting neuroscience and psychology will arise from the study of software." - Alan J. Perlis

"Every program has (at least) two purposes: the one for which it was written, and another for which it wasn't." - Alan J. Perlis

I've yet to see a UML diagram in a professional environment.
