#TIL Linux 的官方 man page 手册除了自带 ASCII 速查表（man ascii），还自带单位数量级速查表。在进行计算时，如果忽然想不起来数量级（1 pF 是十的负几次方法拉第来着？1 TiB 是二的几次方字节来着？），输入 man units 便可立即查阅。
另外：Linux 官方手册还自带 C 语言运算优先级速查表，当看到别人写的代码里有复杂的多条件逻辑表达式拿不定主意时，输入 man operator 立即参考。
We Need to Save What Made Linux and FOSS Possible

Practically all internal communication is done with Facebook, because why not? It's the lowest common denominator. Messaging is done through Facebook messenger, teams are private groups, etc.
Except one group has resisted this: the sysadmins.
Sysadmins need to be able to communicate at all times, /especially/ if things aren't working. And it turns out that there's no way to make sure things like Facebook messenger always work—especially during outages. They're just too damn complicated.
So, they came to a compromise. The rest of the company will move to Facebook, and the sysadmins will stay on IRC, the communication platform they know they can rely on.
When Facebook's on fire and the company is panicking because they can't communicate, you can be sure of one thing: the sysadmins are chatting away on IRC about how to get it working again.
