Это краткая памятка, которая подходит во время вспышки любого респираторного вирусного заболевания. Я ее пишу не для того, чтобы вы срочно начинали все это делать - никакого повода нет. Но, если вы хотите снизить вероятность получения или распространения вирусов - прочитайте.

Общее поведение

1. Контролируйте свою панику. Никакого повода для паники нет, как говорил человек, падающий с пятого этажа, пролетая мимо четвертого: “пока все нормально”. Напомню, уже на вашей памяти у людей была такая же паника из-за птичьего гриппа и атипичной пневмонии. И никакого зомби-апокалипсиса не произошло. Контролировать панику - значит следить за своими реакциями и стараться принимать решения разумно.
2. Не осуждайте чужую панику. Это не помогает ни вам, ни паникующим - каждый человек волен паниковать или не паниковать перед лицом любой опасности. Кроме того, активное осуждение паники вокруг “эпидемий” порождает и подпитывает многочисленные теории заговора, так что просто не надо.
3. Примите разумные меры предосторожно

Stevey's Google Platforms Rant

I was at Amazon for about six and a half years, and now I've been at Google for that long. One thing that struck me immediately about the two companies -- an impression that has been reinforced almost daily -- is that Amazon does everything wrong, and Google does everything right. Sure, it's a sweeping generalization, but a surprisingly accurate one. It's pretty crazy. There are probably a hundred or even two hundred different ways you can compare the two companies, and Google is superior in all but three of them, if I recall correctly. I actually did a spreadsheet at one point but Legal wouldn't let me show it to anyone, even though recruiting loved it.

I mean, just to give you a very brief taste: Amazon's recruiting process is fundamentally flawed by having teams hire for themselves, so their hiring bar is incredibly inconsistent across teams, despite various efforts they've made to level it out. And their operations are a mess; they don't real
