• What time/date do you stamp your deployed data/exe files when they appear on the target system?

  - by Brian Frost

  It seems a good and clean thing to ensure that your deployed files appear on the target system with a consistent time/date. Many Applications seem to do this but other than for care of overwriting Users' existing data I guess it has no real significance. I'm having a purge on my installer packaging and I'd like to know if there any good reasons for specific date/time handling.

• pdf <pre> equivalent

  - by ddowns

  I'm trying to put some code examples in a pdf, but copying them out messes up the formatting and rearranges the lines, there's a lot of manual cleanup needed after pasting. Is there a equivalent to html's pre for PDFs? For "this" block of text respect line breaks, spacing, and copy as plain text like its shown. The closest thing I can see is adding note annotations next to every code example.

  I am creating a sort of "Command line" in Python.

• Authoritative Excel range syntax reference

  - by olefevre

  Sorry if this has been asked before but I can't find it. I am looking for an authoritative description of all valid strings that can be used as a reference, e.g., "A1:C5", "$A:$A", $A2" etc etc. That seems a pretty basic thing yet I've wasted hours trying to locate it.
