Bug fixes & nightmares

time to read 1 min | 148 words

This just happened. I am working on clearing my mail box, when I got a repro for a high CPU load from a user.

Spent an hour trying to figure out what is going on. Found that the problem is something with map/reduce under extreme load.

Couldn’t figure it out. Went to bed depressed after midnight.

Got up at 4 AM, sat down on the same problem. Solved it (root cause, that @ayende guy doing O(N Scary) stuff) in under 15 minutes.

Now I need to figure out what to do with the rest of the night.

Also, currently in Denmark (Copenhagen) and it is bloody cold out here. This is what I look like when I am cold:

I've found that going to the toilet often helps in clearing up stuff :)

You are clearly using too many wrappers.

I long for the day where I finally realize the greatness of "coming back later" such that my work time reduces once more. This has happened to me quite a few times as well and afterwards I get angry for not coming back later - faster. If you hit a wall, stop hitting it again and again - come back later.

Might have something to do with our programmers nature: http://swizec.com/blog/why-programmers-work-at-night/swizec/3198.

Ohh and the facebook share button is creeping out your blog in Chrome 24: https://lh3.googleusercontent.com/-H1rnT8qYhmI/UPaPkrUfF_I/AAAAAAAAWOo/guuZE8Bqczo/s1062/Facebook.png


That's what i call corporate identity. Your scarf is almost #FF8000!


I live in Denmark, born here.

Awful place, don't ever think about staying here for longer periods.


What are you doing in Denmark Rahien? Something exciting, that we danes should attend maybe? :)

Kenneth, I took part in the Warm Crocodile Conference

Dude - we like it cold here in Denmark. Look at it as a way to keep the computers at a steady temperature :D
