This guide provides updated instructions for pairing Bluetooth devices (such as keyboards or mice) in a dual-boot environment with Linux Ubuntu and Windows 10/11, incorporating community feedback and suggestions.

All libraries have subtle rules that you have to follow for them to work well. Often these are implied and undocumented rules that you have to learn as you go. This is an attempt to document the rules of React renders. Ideally a type system could enforce it.
A number of methods in React are assumed to be "pure".
On classes that's the constructor, getDerivedStateFromProps, shouldComponentUpdate and render.

| const config = { | |
| onUploadProgress: function(progressEvent) { | |
| var percentCompleted = Math.round((progressEvent.loaded * 100) / progressEvent.total) | |
| console.log(percentCompleted) | |
| } | |

| data.append('file', files[0]) |

You have a repository, call it alice/repo. You would like to transfer it to the user bob, so it will become bob/repo.
However, you make heavy use of the GitHub Pages feature, so that people are often accessing https://alice.github.io/repo/. GitHub will helpfully redirect all of your repository stuff hosted on github.com after the move, but will not redirect the GitHub Pages hosted on github.io.
You may have experienced when dual booting that you need to re-pair your bluetooth devices (ie., Headphones, mouse, keyboard, etc) this usually happens because you have already paired the device with another operating system using the same bluetooth adapter when dual booting (either Linux or Windows).
Some devices cannot handle multiple pairings associated with the same MAC address (ie., bluetooth adapter). As per suggested on the ArchWiki you can fix this by re-pairing the device each time, but there's actually another solution to not do so each time you choose to use your device on a different OS.
Easy, just pair the device on a OS and copy the bluetooth keys generated to the other OS so our device doesn't notice the difference.
Memoization is a somewhat fraught topic in the React world, meaning that it's easy to go wrong with it, for example, by [making memo() do nothing][memo-pitfall] by passing in children to a component. The general advice is to avoid memoization until the profiler tells you to optimize, but not all use cases are general, and even in the general use case you can find tricky nuances.
Discussing this topic requires some groundwork about the technical terms, and I'm placing these in once place so that it's easy to skim and skip over:
