// assumes you add a timestamp field to each record (see Firebase.ServerValue.TIMESTAMP)
// pros: fast and done server-side (less bandwidth, faster response), simple
// cons: a few bytes on each record for the timestamp
var ref = new Firebase(...);
ref.orderByChild('timestamp').startAt(Date.now()).on('child_added', function(snapshot) {
  console.log('new record', snap.key());
});

Reach UI Philosophy

Reach UI is an accessible foundation for React applications and design systems.

The three equally important goals are to be:

• Accessible
• Composable
• Stylable

Hidden dependencies

Sarah Lim, Northwestern University

Update, September 2019: This Gist detailed an early idea which formed the basis for a major research project. For more information, you can read the resulting full paper, which received Best Paper Honorable Mention at UIST 2018. A tool based on this research is now available on Firefox Nightly.

What are hidden dependencies?

Hidden dependencies between CSS properties are a common source of beginner confusion. For instance, a user might write the following code in order to vertically align some text within a <div>:

Windows 10 version 2004 - Installing Node.js on Windows Subsystem for Linux (WSL/WSL2)

UPDATE (Fall 2020): This gist is an updated version to the Windows 10 Fall Creators Update - Installing Node.js on Windows Subsystem for Linux (WSL) guide, I usually just keep here notes, configuration or short guides for personal use, it was nice to know it also helps other ppl, I hope this one too.

Windows updated windows subsystem for linux to version 2, as the F.A.Q stated you can still use WSL version 1 side by side with version 2. I'm not sure about existing WSL machines surviving the upgrade process, but as always backup and 🤞. NOTE: WSL version 1 is not replace/deprecated, and there ar

Interaction tracing with React

React recently introduced an experimental profiler API. After discussing this API with several teams at Facebook, one common piece of feedback was that the performance information would be more useful if it could be associated with the events that caused the application to render (e.g. button click, XHR response). Tracing these events (or "interactions") would enable more powerful tooling to be built around the timing information, capable of answering questions like "What caused this really slow commit?" or "How long does it typically take for this interaction to update the DOM?".

With version 16.4.3, React added experimental support for this tracing by way of a new NPM package, scheduler. However the public API for this package is not yet finalized and will likely change with upcoming minor releases, so it should be used with caution.
