Are you using an actual debugger, like in IntelliJ? I seem to recall that it was actually a somewhat pleasant experience. The tool itself, that is. Unravelling the mysteries of stateful Java can be painful regardless of the tool 🙂

No, I’m trying to figure out why Tomcat isn’t working correctly

I was recently debugging Java via emitted JSON for consumption by CDK ... such fun 🙂

simongray12:03:53

fun times @U04V5V0V4 🙂

Anyone wants to try the new JDK19 virtual threads? Go download bb 1.2.174 because it ships with them :)

Sweet! Was it a smooth ride adding support? I'm considering vthreads for a native image as well.

borkdude08:03:52

Yeah, no problem at all

Good morning! I want to create a 3D-animation, real time, web-based, that I can feed some data and it will be able to animate that data smoothly. No clear idea about how the animation would look, but we're not talking any huge amounts of data, maybe 10K data points, tops. It's time based, 10+ years with a data point per day. I might want to be able to add interactions, hover, etc. Any suggestions for what to use for building it? I want butter smoothness.

@U0ETXRFEW plexus shared something like this in #C06MAR553 today. Also @U017QJZ9M7W may know something, perhaps in combination with clerk

borkdude16:03:19

And @U07SQTAEM may also know something

Sam's been doing some good work around visualizations in the browser from CLJS recently, using libraries like Mafs. I've usually done this from scratch using WebGL, but that's not really what I recommend.

http://Mathbox.Mentat.org is a solid set of primitives, see http://Mathbox.org for a ton of examples

pez16:03:40

Thanks!!!

pez16:03:33

> I've usually done this from scratch using WebGL Yeah, forgot that part. I want butter smoothness + an as easy time as possible. 😃

pez16:03:18

http://mathbox.mentat.org/ looks like exactly what I was looking for. OMG, that demo!

Daniel Craig17:03:19

Could one make a force-directed graph using Mathbox?

Sam Ritchie18:03:25

I’m sure yes! But you wouldn’t get it for free with the existing primitives, I think there are some similar examples

Sam Ritchie17:04:03

@U0ETXRFEW checking in to see how it’s going!

Sam Ritchie17:04:43

I’ve been hacking up some mathbox stuff here

Using Emmy to get functions across the wire and running fast, maybe there’s something useful there

pez17:04:36

Never got to even start this. Right now I have forgotten what it was I wanted to do. 😃 But super happy to know this library exist! Gonna abuse it one of these days.

pez17:04:48

Emmy? 👀

Here is a bit of writing on it I out out recently

pez17:04:27

The examples are CRAZY!

Sam Ritchie17:04:50

Can’t wait to get it all tidied!! What is so rad about clerk is when you run these locally, you Change something deep in the potential energy function etc and everything snap updates

Sam Ritchie17:04:05

I’m still figuring out how this should feel

Sam Ritchie17:04:17

Haha but thank you for that reaction :)

Sam Ritchie17:04:24

That’s what I’m going for!

pez20:04:44

You are succeeding. Blows my mind to interact with the things.

I'm glad you're speaking at Conj, I can't wait
