Hey, it's HighScalability time:
- Quotable Quotes:
- @jezhumble: Google does everything off trunk despite 10k devs across 40 offices.
- @KentLangley: "in 2016. When it goes online, the SKA is expected to produce 700 terabytes of data each day"
- Jonathan Marks: It's actually a talk about how NOT to be creative. And what he [John Cleese] describes is the way most international broadcasters operated for most of their existence. They were content factories, slave to an artificial transmission schedule. Because they didn't take time to be creative, then ended up sounding like a tape machine. They were run by a computer algorithm. Not a human soul. There was never room for a creative pause. Routine was the solution. And that's creativities biggest enemy.
- 40% better single-threaded performance in MariaDB. Using perf, cache misses were found and the fix was using the right gcc flags. But the big hairy key idea is: modern high-performance CPUs, it is necessary to do detailed measurements using the built-in performance counters in order to get any kind of understanding of how an application performs and what the bottlenecks are. Forget about looking at the code and counting instructions or cycles as we did in the old days. It no longer works, not even to within an order of magnitude.
Don't miss all that the Internet has to say on Scalability, click below and become eventually consistent with all scalability knowledge...
