Wayland vs. X – Overview
libei looks useful. But IDK why libei is necessary to run Barrier with Wayland?
For client systems, couldn't there just be a virtual /dev/inputXYZ that Barrier forwards events through
And for host systems, it looks like xev only logs input events when the window is focused.
Is xeyes still broken on Wayland, and how to fix it so that it would work with Barrier?
With Barrier, when the mouse cursor reaches a screen boundary, the keyboard and mouse input are then passed to a different X session on another box until the cursor again crosses a screen boundary rule.
Barrier is a fork of Synergy's open core: https://github.com/debauchee/barrier

KVM Switch for Gaming and WFH
I have a similar gaming/WFH setup (2 monitors at 1440p 144hz) and I’ve been using Barrier instead of a physical kvm, and it works really well. Not sure if you’re open to a software kvm but if you are, I’m happy to answer any questions about it if you have any.

Autoswap Keyboard Layouts based on Operating System
Have you tried Barrier? I casually used it to swap between my main rig and my MBP. Took a minute to get it setup but once I sorted it all out it worked pretty well. It has some settings and tweaks built in to address some of the layout issues you mentioned...

IT/programming multi-monitor setup? (coming from 6x old 21" square)
Sorry, probably not entirely on topic and can't answer anything reliable about the multimonitor stuff, but a tip regarding the 2 mice and 2 keyboards for the 2 different computers: use this: https://github.com/debauchee/barrier It's oss multi-os software that lets you use one mouse and keyboard (server) on several PCs (clients) easily over your LAN.

Ask HN: What are some 'cool' but obscure data structures you know about?
Tries (or prefix trees).
We use them a lot at Pyroscope for compressing strings that have common prefixes. They are also used in databases (e.g indexes in Mongo) or file formats (e.g debug symbols in macOS/iOS Mach-O format are compressed using tries).
We have an article with some animations that go into details about tries in case anyone's interested [0].

Question: How do you handle oversized heap analysis?
You could use continuous profiling with Pyroscope which uses async-profiler under the hood, but with the added functionality that you can add relevant tags to your VMs (example).

JFR (Java Flight Recorder) Parser written in Go
Java Flight Recorder (JFR) is a format for collecting diagnostic and profiling data from Java applications. A while back someone created an issue for Pyroscope , an open source continuous profiler written in Go, to support ingesting profiles in JFR format, but there were no existing parsers that were also written in Go.

We created flamegraph.com - A website for uploading, analyzing, and sharing flamegraphs
At Pyroscope (open source continuous profiling) we use flamegraphs extensively to visualize and analyze profiling data. However, one of the worst parts about using flamegraphs for analysis is that they are kind of annoying to share.
