Give Your Tail a Nudge
[[Nudge]] Optimizations for [[FCFS]]:
The intuition behind the Nudge algorithm is that we’d like to basically stick to FCFS, which we know is great for handling the extreme tail (high ?), while at the same time incorporating a little bit of prioritization of small jobs, which we know can be helpful for the mean and lower ?.
However, when a “small” job arrives and finds a “large” job immediately ahead of it in the queue, we swap the positions of the small and large job in the queue. The one caveat is that a job which has already swapped is ineligible for further swaps.
Ops to Bots — Smartening incident recovery

In Bash, redirect both standard output and standard error:

Why MTTR should be a ‘business’ metric
Ex: A practice from Last9 I love: 2 day auto-delete messages on personal DMs in slack, because you want to control the spread of tribal knowledge; forcing engineers to talk on public slack channels. (Full disclosure: I’m an investor in Last9 )

2022-43: Self-regulation at work
When the enthusiasm for work is high, various grand reconstruction schemes and planning functions are always proposed, and the various challenges and difficulties encountered are not a problem; Difficult to muster the courage to take the first step, full of frustration and failure. In order to ease this mood, I chose to put these particularly big plans on hold first, start with some small and specific work, and restore my senses through stable delivery.
When you are in a bad state at work, you can try to adjust from the external environment and the work itself, chat more with your friends and loved ones, and actively adjust and persevere. I wish everyone can get out of the difficult time as soon as possible, and the good days are still to come~
