choroba had a Christams party at work yesterday. Slow morning today...
[Corion]: I guess I should not read some discussions on HackerNews - the crowd there is weirdly different - "you have to stay current in tech" (by following all the latest JS trends) is a meme there, but it doesn't really match my experience
[Corion]: At least in my area, experience can beat most new tech anyway because most new tech is just a rehash of things abandoned in the 70s and we still have a lot of that ;)
[Corion]: choroba: Ah, that will be next Friday for $work ;) Drinking enough water is key ;))
[Corion]: But then, maybe that's just my experience with things, and maybe Hacker News is just people much younger who haven't seen more than one tech cycle...
[choroba]: s/water/bear/ and s/enough/too much/
[choroba]: beer
[choroba]: oh ok
[marto]: I crashed the ScotLUG Christmas night, having never actually been to ScotLUG
[choroba]: Corion yeah, I probably already told you about how Bjarne Stroustrup was asked whether he still watched the new tech trends and what really impressed him
