Now the talk I’m looking forward to the MOST - @colmmacc on PID loops (pronounces P-I-D loops, and not “pid” (like sid) loops as I’ve always been pronouncing it in my head.
This is going to be so good! I’ll try to live tweet.

EBTree is a very interesting data structure used in HAProxy. This talk goes into the design of EBTrees given the scheduling requirements of an event driven load balancer.
TIL the Linux scheduler used to use a linked list, before the red-black tree based CFS became the default.

Sorry couldn’t manage to live tweet this talk. I’m too engrossed in the talk to be tweeting.
It’s a really great talk on a very cool data structure. Here’s some pretty pictures #qcon

HAProxy’s event loop and task schedule put together.
Keeping the timers and the run queue ordered is no small feat. The whole talk was about data structures in haproxy that make this happen.
Allows for 100ns inserts, > 250K TCP conn/second and >350K http conns/sec!! #qcon

Gosh, I'm so delighted when I see people take the basics of mapping and ... well frankly, find better ways of doing it. This is why you make a field open, it's how we progress as an industry.
it's far more interesting and potentially granular than my cheat sheet. Oodles and oodles of potential, cross comparison between individuals etc.
On, that note, I was asked at #QCon whether I had considered others axes for evolution. The answer is, I use one axis (activities) to describe the four stages of evolution of capital for all the different forms of capital ...
Watching a talk on event drive architectures at #qconlondon #qcon. Interested simply to find out exactly how much #serverless simplifies everything.
Talking about Dash Buttons and how to work with them. Talking about decoupling services when a button is pressed. I think it's going to go down the road of explaining an event driven approach...
It's interesting to note that the speaker is talking about "services" that are created... in my mind, most of these things are incredibly simple Lambda functions.
