Regular expressions fall into this category. While they might take longer to master, you should know the basics after an hour.

I've been surprised at how often people convert long lists line-by-line. You can sometimes take what was a multiple-hour task and complete it with a handful of cryptic characters.

Mindfulness meditation. Sitting with your thoughts and emotions, experiencing them, and understanding them, rather than avoiding them or distracting yourself from them can have a dramatic effect on your life. And 10 minutes a day for a week can get you far enough to see some real benefits, like reduced stress and increased awareness of unhelpful thought patterns.

Git. It has few commands and can be rapidly learned in one hour, mastering commands such as Git fetch Git pull Git commit Git push Git merge Git log

I doubt people with no prior dvcs experience can learn git in an hour. The interface is abysmal, it uses multiple terms for the same concepts, it's a mess generally.

CPR/Choking/First Aid course is probably close to an hour.

How to change your own oil - probably lots of other money-saving home and auto DIY things...

Speed reading and memory tricks can be a multiplier on learning other skills.

How to use automation tools like Zapier and IFTTT - again, a force multiplier.

There's a growing realization that you can completely side-step the need for Single-Page App frameworks like React using websockets and the morphdom library. Projects like StimulusReflex (Rails) and LiveView (Phoenix) allow developers to build complex, reactive modern apps faster and easier by rejecting the need to even have client state. https://github.com/hopsoft/stimulus_reflex https://github.com/phoenixframework/…

neat! Of course, this makes me want to run React serverside...

How to do various knots comes to mind. Square knot, A sheet bend, clove and trucker's hitch, prusik, the alpine butterfly knot, and bowlines can all be learned rather quickly, then practiced so they can be remembered easily. http://paracord550milspec.com/wp-content/uploads/2016/06/How...

I remember learning these before but due to not finding any use case for them, I already forgot how to do them properly.

Only thing I regularly tie nowadays are my shoelaces.

EDIT: Grammar
