20 odd years ago I worked on someone else's helpdesk as application and PC support. Sometimes the calls that came in were a bit more interesting than Extra Term is blinking at me or Sophos ate my Word doc. Call (ticket) came in along the lines of "Need help with a neural network I am developing in Excel". I bit. I showed the end user (who was orders of magnitudes cleverer than me) a bit about VBA. Some reasonably good habits like Option Explicit and making sure all eventualities are covered in If clauses. Keep your inputs, working and output separate and sum north/south and east/west and compare. Document the bloody thing! If I recall correctly, it was a Hopfield thingie, so I'm pretty off topic here. The next call was for help with an Access database with fifty odd tables all linked to each other in a way that must surely be designed to invoke Cthulhu. I deleted it and we started again! My call notes were odd enough to get a mention at the next ops meeting. The product is still flying so all good. Convoluted ... what?
