I have a Microsoft Family account and have my daughter as one of the family members.

Whenever she tries to play Minecraft (Java Edition) with us, it pops up something like the following:

"Multiplayer is disabled. Please check your Microsoft account settings."

I tried all kinds of things found online. They kept saying to go to the Xbox Privacy and online safety screen, but I couldn't find the "You can play with people outside of Xbox Live" and "You can join multiplayer games" settings. Well, that's because I needed to click on the "Xbox Series ... and Windows 10 devices Online Safety" tab.

Here's a direct link. You will need to replace the "GAMERTAGHERE" with your child's gamer tag. You need to be logged in under your (parental) account, not the child's.

Understanding Nix Inputs

Every Nix derivation produces a Nix store output that has 3 things:

Executables
Libraries
Data

Executables are always exported using the PATH environment variable. This is pretty much automatic.

If you are annoyed that "Sources for Android 26" are not yet available via SDK manager, this might be for you:

Collect source files

mkdir android-sdk-source-build
cd android-sdk-source-build

mkdir -p frameworks/base

Go Pipelines

This document demonstrates a basic pipeline in Go and talks about a risk in in implementing them. Keep in mind that:

Using FizzBuzz here is contrived, but quite a nice way to demonstrate the concept. Obviously there is no advantage to running the basic workload of FizzBuzz in a Goroutine, but if the task involved heavy computation or long lived I/O, it starts to make a lot more sense.
The problem discussed only applies to Goroutines that actually need to have a way to

What forces layout / reflow

All of the below properties or methods, when requested/called in JavaScript, will trigger the browser to synchronously calculate the style and layout*. This is also called reflow or layout thrashing, and is common performance bottleneck.

Generally, all APIs that synchronously provide layout metrics will trigger forced reflow / layout. Read on for additional cases and details.

Element APIs

Getting box metrics

elem.offsetLeft, elem.offsetTop, elem.offsetWidth, elem.offsetHeight, elem.offsetParent

Getting the code

git clone https://gist.github.com/6780d7cc0cabb1b4d6c8.git

Executing the code

$ npm install # maybe npm start will take care of it but just in case
$ npm start && open out.png

nix-shell and Shebang Lines

A few days ago, version 1.9 of the Nix package manager was released. From the release notes:

nix-shell can now be used as a #!-interpreter. This allows you to write scripts that dynamically fetch their own dependencies.
