Learning Technologies makes some interesting WASM powered software, I'm glad to see people are making a living working on this.
Your article was much better, but I do wish the linked deep dive on CheerpJ was a bit meatier, it's more of an overview. A deeper dive about the trade offs of the implementation and other challenges you faced getting the JIT working inside WASM would certainly do well here.
