Spaces or Tabs?

Spaces for consistent viewing across various editors and different implementations of the tab character. With that said I have my editors set to insert spaces each time I press the tab key instead of inserting the tab character. Silicon Valley is pretty humorous and I got a pretty good laugh about the space versus tabs, but there are actually style guides in companies that define how you code in the real world. Google, for example, uses spaces. Facebook uses a tool to correct whitespace errors not in accordance with their style guide.

Just a coding practice when you work in a group, on the same program.

The "rules" are set by the head programmer, in such a way that any piece of code can have been written by anyone, and are indistinquishable between them.

In UK, we had a team working on a totalisator, and we were "obliged" to add a "PDL" (Programming Development Language) for each function. This was, in layman's terms, what the function did, what parameters it receives, and what are returned values. A little like a ".h" file (C). It has the advantages that you avoid repeated functions, names that "say what they do". The collection of all PDL went to another file that built the whole "manual" for the code.

And, yes, we did use tabs instead of spaces, and I would not tolerate spaces :-) (nor "blank lines")

I still do use the same protocols. The discipline forces you to write clear, understandable, easy to maintain and well commented code.

But, again, who really cares?
