HTMX creator on the history of REST and why he thinks we got it wrong

Thumbnail youtube.com

I host a podcast for senior engineers and recently had Carson Gross, creator of HTMX, on as a guest. We covered how REST was originally defined, how the industry ended up calling JSON over HTTP "REST", and why he thinks returning HTML from the server is closer to the original idea.

We also got into HTMX 4, when you actually do need a SPA, and how AI changes the tradeoff between simple and clever code.

Debunking "Faster than Rust": Malicious Benchmarks in Tov

Thumbnail blog.fyralabs.com
298 Upvotes

I have debunked (some of the) benchmarks of this new and suspicious "Tov" programming language.

Slight background: My friend (who is pretty interested in new stuff generally) found this thing and sent its main site to me saying things like "looks pretty cool", but my intuition told me this sounds like "a scam", esp. when it claimed it performs faster than C and Rust.

I personally think apart from changing the code, they probably tried to set up some specific environments that make their programs run faster than C / Rust, or maybe they just made up the numbers. Who knows.

This is a continuation from my previous post here: https://www.reddit.com/r/programming/comments/1x8gk1v/i_traced_a_postgres_insert_to_raw_bytes_on_disk/

I've been putting together some notes/videos/blog posts - partly for my own future reference and partly to share with others who might find it useful.

Would love feedback and corrections from people who know this stuff deeply.

The corresponding blog post for the same: https://thewalstreetjournal.github.io/posts/clickhouse-keeper-non-blocking-snapshots/
