There is nothing as permanent as a quick fix

Will we see the day where software is legistated? Politicians deciding: - What coding languages we can use - What platforms to write on - What courses we have to take - What books to read

You: "I just coded a real masterpiece! Only I and God two know how it works." Also you, 3 months later: "Now only God knows."

"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 two ways of constructing a software design: One way is to make it so simple that there are obviously no deficiencies and the other way is to make it so complicated that there are no obvious deficiencies." —C.A.R. Hoare, The 1980 ACM Turing Award Lecture

There are 6 basic types of values in JavaScript - numbers (64 bits) - strings - Booleans - objects - functions - undefined values

Programmers are good at finding valid reasons for making poor decisions
