So as is traditional a quick reminder for myself of what my todo list was looking like:
So, as is traditional, I didn’t get to spend much time on it this week, if only I didn’t have any family or freinds or leisure activities I might have more time to write a crappy message board application. Oh well.
But have managed to prove that I should be able to use a gmail account to send notification emails from – not sure if this is an advantage or not over setting up an email server, but in the spirit of just getting something working in whatever way is easiest it does the job.
Also a bit of tweaking of nginx config seemed to be having no effect, despite “ctrl shift delete, delete all cache” in firefox, which stumped me till I found a default file in /etc/nginx/sites-available which was what seemed to be taking precedence. Or maybe nginx wasn’t reloading the config like I thought it was when I ran “nginx -s reload”. Anyway, it’s working now, but need to experiment a bit to be confident that I’ve got any sort of a clue as to why.
