Check for if (-1 == x) instead of if (x == -1) to avoid bugs like if(x = -1)
Theory is when you know something, but it doesn't work Practice is when something works, but you don't know why Programmers combine theory and practice Nothing works and they don't know why
"Every program has (at least) two purposes: the one for which it was written, and another for which it wasn't." - Alan J. Perlis
"The only constructive theory connecting neuroscience and psychology will arise from the study of software." - Alan J. Perlis
"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 significant bugs in our released software that any significant number of users want fixed." - Bill Gates
"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)
"Measuring programming progress by lines of code is like measuring aircraft building progress by weight." - Bill Gates
