Today we spliced some fibre cable, and I, for the very first time, was able to connect and patch fibre with my co-workers.
I dunno why, but somehow cutting and crimping glass cable gives me a thrill.
On top of that, we were able to dramatically increase the speed of the primary school's network. No more waiting for minutes to load pages and send mail, now they will wait for seconds!
Any day where you get to drill holes in walls, bolt stuff in, use a metal grinder, and patch networking is a good day.
