Created by MongoDB, attempts to be even more restrictive than AGPL by more explicitly saying that indirect automatic requests are also included in the "you must give source" domain: opensource.stackexchange.com/questions/8025/difference-between-mongodb-sspl-and-gnu-agpl

The base use case is:which is what MongoDB is trying to ensure, which sounds fair.

Uses Redux, while reactjs/react-rails appears to do that more manually

Lots of focus on Heroku deployability, which is fantastic: shakacode.gitbooks.io/react-on-rails/content/docs/additional-reading/heroku-deployment.html

Live instance: www.reactrails.com/ with source at: github.com/shakacode/react-webpack-rails-tutorial Not the most advanced web-app (a gothinkster/realworld-level would be ideal). Also has clear dependency description, which is nice.

Trying at github.com/shakacode/react-webpack-rails-tutorial/tree/8e656f97d7a311bbe999ceceb9463b8479fef9e2 on Ubuntu 20.10. Got some failures: github.com/shakacode/react-webpack-rails-tutorial/issues/488 Finally got a version of it working at: github.com/shakacode/react-webpack-rails-tutorial/issues/488#issuecomment-812506821

Oh, and the guy behind that project lives in Hawaii (Ciro Santilli's ideal city to live in), has an Asian-mixed son, and two Kinesis Advantage 2 keyboards as seen at twitter.com/railsonmaui/status/1377515748910755851, Ciro Santilli was jealous of him.

Worked on Ubuntu 20.10.

The UI is a bit too buggy to bear.

How to unsplit, can't find on shotcut 21.05.01: forum.shotcut.org/t/is-it-possible-to-unsplit/1466/2

Background noise reduction: couldn't easily find out how, especially with automatic profile detected based on a selected region as mentioned at audacity profile-based background noise removal:

Hyperthreding is the Intel brand-name, TODO generic name.

It is not a practical fighting style. But it is an awesome game/exercise.

TODO why it is optimal: physics.stackexchange.com/questions/149214/why-is-the-carnot-engine-the-most-efficient

The key question is: why is this not symmetrical?

One answer is: because one of the twin accelerates, and therefore changes inertial frames.

But the better answer is: understand what happens when the stationary twin sends light signals at constant time intervals to each other. When does the travelling twin receives them?

By doing that, we see that "all the extra aging happens immediately when the twin turns around":

Another way of understanding it is: you have to make all calculations on a single inertial frame for the entire trip.

Supposing the sibling quickly accelerates out (or magically starts moving at constant speed), travels at constant speed, and quickly accelerates back, and travels at constant speed setup, there are three frames that seem reasonable:

If you do that, all three calculations give the exact same result, which is reassuring.

Another way to understand it is to do explicit integrations of the acceleration: physics.stackexchange.com/questions/242043/what-is-the-proper-way-to-explain-the-twin-paradox/242044#242044 This is the least insightful however :-)

Let's show them how it's done with primes + awk. Edit. They have a -d option which also shows gaps!!! Too strong:gives us the list of all twin primes up to 100:Tested on Ubuntu 22.10.
