I'm into cycling as well but I'm old-fashioned and therefore I think Strava is the devil's work No, seriously, I even had professional ambitions in my youth, but now I just enjoy riding without being addicted to measure and optimize every parameter there is.
Odd non-code based question "can anyone here (Mike, Griff et al.) recommend a web site that gives details of multilayer PCB, I need to refresh on the design principals before an interview. I just want to know when is the correct time to multilayer a board, my answer was going to be when the track width is such you can't fit any more on one layer. I'm guessing there is a better judged answer...
It depends, obviously you do not want sensitive front end circuitry to be bombarded with EMI (Electromagnetic Interference) so a multi layer board that includes a ground plane would provide EMI shielding. This is true in the reverse for circuits that emit a lot of noise such as power supplies or switching circuits.
It used to be a cost factor issue but over time this is generally no longer a large cost increase. 4 layer PCBs are very common even for simpler circuits.
Decrease the belief in God, and you increase the numbers of those who wish to play at being God by being “society’s supervisors,” who deny the existence of divine standards, but are very serious about imposing their own standards on society.-Neal A. Maxwell
You must accept 1 of 2 basic premises: Either we are alone in the universe or we are not alone. Either way, the implications are staggering!-Wernher von Braun
Only joking, I have just been presented with a very small issue, just wondering if those of you who like this sort of thing might be able to come up with an elegant solution, just for fun.
I have a field that has a text string in it.
The text string will probably contain an error code, but might not.
The error code, so far as I can tell, will be 2 letters followed by 6 numbers or 3 letters followed by 5 numbers.
The error code, so far as I can tell, will be at the start or the end of the text string.
I need to extract the error code (should it exist) into a new field and the rest of the string into another.
Typing the question has, I believe, shown me the way to proceed.
Bonus credit; I have to do it in xsl.
I shall do it as soon as Eclipse starts working again.

ps, don't you love it when companies apply no standards whatsoever to their work.
pps, if I'm honest I just wanted to complain about the lack of standards
ppps, I think it is due to developers who assume everything they create will be read by a human rather than by a computer
Some men are born mediocre, some men achieve mediocrity, and some men have mediocrity thrust upon them.
