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.

flamegraph.com - a new website for uploading, analyzing, and sharing pprof profiles
This cloud version is actually a slimmed-down version of Pyroscope which is open source and so you can run it locally.

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.

Linen.dev β Building a chat app with Elixir and NextJS
The best language for the task at hand, when presented with time constraints, is the one that you already know well. OP said in the article that they authored Papercups [1]. Adopting Elixir for a websocket-push service makes a lot of sense, then. However, why don't you learn Elixir, some OTP, and then reconsider that question? You could be missing out.

Ask HN: What novel tools are you using to write web sites/apps?
Phoneix - Elixir
We're a live message tool and it is basically what Elixir is built for https://github.com/papercups-io/papercups.
The Elixir community has been great and incredibly friendly. I originally was worried about the size of the community but that hasn't been an issue the community has been super helpful. I also think the annual stackoverflow usage surveys are very misleading because most of the community's questions get asked in ElixirForum and not on Stackoverflow.
Phoneix is the web framework of Elixir which is very similar to Rails but minus a lot of the magic has been very helpful for our productivity as well.
If I had to built another service that is websocket heavy I would definitely use Elixir. Even if it was a standard crud app I would still most likely choose Elixir.
