Installing Windows and Linux into the same partition

But WHY?

There was a reddit post about installing Arch on NTFS3 partition. Since Windows and Linux doesn't have directories with same names under the /(C:\), I thought it's possible, and turned out it was actually possible.
If you are not familiar to Linux, for example you've searched on Google "how to dualboot Linux and Windos" or brbrbr... you mustn't try this. This is not practical.

Pre-requirements

UEFI system
Any Linux live-boot CD/DVD/USB... with Linux kernel newer than 5.15
Windows installer USB

GitHub GraphQL API v4 Examples

Here are two queries that look up information about a pull request via GitHub's GraphQL API v4. The first looks up a pull request by number, the second looks up a pull request by ref (i.e. commit hash, branch name, tag name).

Why tho

While it is trivial to use the RESTful v3 API to look up a pull request by number, the GraphQL API is the only way to do the same thing for an arbitrary reference in a single HTTP request.

These took a bit of trial and error in the GitHub's GraphQL Explorer and various support threads to get right, so I'm putting them up here for posterity.

React - Functional error boundaries

Thanks to React hooks you have now happily turned all your classes into functional components.

Wait, all your components? Not quite. There is one thing that can still only be implemented using classes: Error boundaries.

There is just no functional equivalent for componentDidCatch and deriveStateFromError yet.

Proposed solution

UPDATE (March 2020, thanks @ic): I don't know the exact AMI version but yum install docker now works on the latest Amazon Linux 2. The instructions below may still be relevant depending on the vintage AMI you are using.

Amazon changed the install in Linux 2. One no-longer using 'yum' See: https://aws.amazon.com/amazon-linux-2/release-notes/

Docker CE Install

sudo amazon-linux-extras install docker
sudo service docker start

Migrate GPG Keys from One Workstation to Another

Replace [your key] with your key ID

To obtain your key ID

gpg --list-secret-keys --keyid-format LONG

Which returns something like

Improved .visually-hidden

Theorically bulletproof CSS class for visually hide anything and keep it accessible to ATs.
