The tree below represents a React application mounting. During mount, two components read from an external, mutable source. The first one (List) reads version 1 of that data and the second one (Item) reads version 2.

How to setup a development environment where Git from WSL integrates with native Windows applications, using the Windows home folder as the WSL home and using Git from WSL for all tools.
Note if using Git for Windows, or any tool on the Windows side that does not use Git from WSL then there will likely be problems with file permissions if using those files from inside WSL.
These are the tools I use:

While the public API intended for users to use is the scheduler package, the reconciler currently
does not use scheduler's priority classes internally.
ReactFiberScheduler has its own internal "mini-scheduler" that uses the scheduler package
indirectly for its deadline-capable scheduleCallback.
This is kind of a documentation of implementation details that I suppose will be gone by the end of the year, but what can you do.
Well, that was unexpected. In the following, I’m trying to follow Jon Evans’ advice from “The Terrible Technical Interview”.

Hi there! Thanks for offering to let me take a HackerRank test for ABC, I appreciate the vote of confidence.

This is a compiled list of falsehoods programmers tend to believe about working with time.
Don't re-invent a date time library yourself. If you think you understand everything about time, you're probably doing it wrong.
Okay, the title of this post is a bit of a lie. There's no one secret trick to becoming a genius programmer - there are two, and they're more habits than tricks. Nevertheless, these kind of 'secret tricks' seem to resonate with people, so I went for this title anyway.
Every once in a while, a somewhat strange thing happens to me. I'll be helping somebody out on IRC - usually a beginner - answering a number of their questions in rapid succession, about a variety of topics. Then after a while, they call me a "genius" for being able to answer everything they're asking; either directly, or while talking about me to somebody else.
Now, I don't really agree with this "genius" characterization, and it can make me feel a bit awkward, but it shows that a lot of developers have a somewhat idealistic and nebulous notion of the "genius programmer" - the programmer that knows everything, who can do everything, who's never stumped by a problem, and of which ther

When writing django apps it's easy to ignore the organization of your front end code. Often, these backend coders will just write a static js and css file, stick it in the static directory, and call it a day.
You can also build them as two completely independent parts. With a complex gulp build routine independent of the django app. But if you don't know gulp, node, or those kinds of systems it can be a daunting process to get started with.
Enter django-compressor-toolkit (the name doesn't quite roll off the tongue).
Using django-compressor and django-compressor-toolkit you can write Javascript ES6 code with all its fancy import/export logic or style your pages with sass instead of css, and leave your deploy routine largely untouched.
