Note: Since this seems to be helpful to some people, I formatted it to improve readability of the original. Also, note that this is from 2016, many things may have changed, and I don't use macOS anymore, so I probably can't help in case of questions, but maybe someone else can.

Mac Network Commands Cheat Sheet

After writing up the presentation for MacSysAdmin in Sweden, I decided to go ahead and throw these into a quick cheat sheet for anyone who’d like to have them all in one place. Good luck out there, and stay salty.

Cool Tech? UNPHAT.

Next time you find yourself Googling some cool new technology to (re)build your architecture around, I urge you to stop and follow UNPHAT instead:

1. Don’t even start considering solutions until you Understand the problem. Your goal should be to “solve” the problem mostly within the problem domain, not the solution domain.
2. eNumerate multiple candidate solutions. Don’t just start prodding at your favorite!
3. Consider a candidate solution, then read the Paper if there is one.
4. Determine the Historical context in which the candidate solution was designed or developed.
5. Weigh Advantages against disadvantages. Determine what was de-prioritized to achieve what was prioritized.
