I gave a talk at Helvetic Ruby 2024 about Crystal. It’s tailored to the perspective of Rubyists, but prior Ruby experience is not required to follow along.
There were many more interesting talks by awesome speakers. I can recommend taking a look at them as well. They’re not only relevant for Rubyists.
Some examples of talks I enjoyed:

This is great !
But where can we get Crystal t-shirts like yours from? 
We had printed a batch for CrystalConf 2023.
Eventually we’d like to sale merch through a print on demand provider. But we haven’t gotten around to figure something out yet.
Very cool. I would definitely buy one
@straight-shoota , i really think you should purchase（or apply) a new laptop.
Following come from your’s slide.
Following come from my laptop (AMD 7840hs on Arch linux, a relatively ordinary and cheap config in 2023)
It looks like your performance isn’t half as good as mine, even another window is still playing a youtube video when do benchmark, this seriously underestimates Crystal’s performance.
Thanks for testing this. I don’t recall the exact circumstances of this test.
You’re right that it appears to be quite underperforming for modern hardware. I just ran the test on my machine and it shows significantly better results, more similar to yours.
Again, I’m not sure how the numbers from the talk happened to be that low.
It’s probably not very relevant though because raw performance of an HTTP server that renders only “Hello World” on every request is not very meaningful anyway.
I know I’m a little late to this thread … I bought one that looks just like it from Amazon
Good call, I’ll look it up, thanks
