1. There are two and only two genders.
2. Okay, then there are two and only two biological genders.
3. Gender is determined solely by biology.
4. Okay, it’s mostly determined by biology, right?
5. Please tell me it’s determined by DNA.
6. Gender can be reliably determined through visual means. After all, no man would ever wear a burka.
7. Once gender is set, it never changes.
8. Even if the gender can change, it will only change from the one value to the other value.
9. Only one gender can be “active” at the same time.
10. We’re tracking gender now, so we’ve always tracked it.

System Design Cheatsheet

Picking the right architecture = Picking the right battles + Managing trade-offs

Basic Steps

1. Clarify and agree on the scope of the system

• User cases (description of sequences of events that, taken together, lead to a system doing something useful)
  • Who is going to use it?
  • How are they going to use it?

FWIW: I (@rondy) am not the creator of the content shared here, which is an excerpt from Edmond Lau's book. I simply copied and pasted it from another location and saved it as a personal note, before it gained popularity on news.ycombinator.com. Unfortunately, I cannot recall the exact origin of the original source, nor was I able to find the author's name, so I am can't provide the appropriate credits.

• execution time of read/write syscall for each file descriptor and summarize execution time for each 1 sec period,
• calulates amount of read/write syscalls for each file descriptor

strace log must be collcted with -t -T -f options.

On Ubuntu 16.04 LTS, I successfully used the following to disable suspend:

sudo systemctl mask sleep.target suspend.target hibernate.target hybrid-sleep.target

And this to re-enable it:

sudo systemctl unmask sleep.target suspend.target hibernate.target hybrid-sleep.target
