Michał
Karnicki

Software engineer
from Poland 🇵🇱

Born in Slupsk, a town in the Poland, this snowboard fan has now settled in the beautiful city of Warsaw. His weak spots? Reading, albeit books of the technical sort.

Algorithms and problem solving are high on Michal's list as well, although these days his focus is more product orientated. With music being his passion, his office is also a music production studio. The best song ever written is Teardrop by Massive Attack. Nothing beats the line ‘Teardrop on the fire, fearless on the breath.’

If you would've wanted to invent something, what would it be?
I wanted to invent a bicycle, but that's already done. I guess a stable cold fusion reactor would be pretty rad to put on your inventions list.

Why should we visit Warsaw?
Poland has some beautiful places worth visiting in general. But if you really want a breathtaking view, visit Warsaw on August 1st. Experience how time stops at 5PM sharp to commemorate the Warsaw Uprising. It gives me the chills every year again.

A dial, not a switch: staging a risky migration with hash-bucket cohorts

Processes

A boolean feature flag starts a risky migration everywhere at once. Hashing a stable tenant ID into 100 buckets turns the flag into a dial that only ever widens, and the thresholds matter: percent-of-tenants is not percent-of-work.
