If it helps, I (original author of proto2) have been advising Buf and like what they're doing. (Disclosure: I also invested a small amount.) Buf is founded by engineers who spent a LOT of time working with Protobufs outside of Google.

The 1900's were the twentieth century. Except the year 1900 specifically was still the nineteenth century; the twentieth century started in 1901 and ended at the end of 2000, much to the chagrin of all the chumps who celebrated the m

I do very much appreciate that "deprecated" in Java only means "there's a better way to do this" and absolutely does not mean "this will go away". Serious platforms never break backwards compatibility.

No, because the acquisition makes AppLovin more valuable. If merging with Unity makes AppLovin $17.5B more valuable than it was previously, then the existing stock's value doesn't change. Of course, the market may disagree on the

I agree with all this. Java is a great application programming language. But bullen was arguing that Java is the best for servers of all types, which is what I object to.

Of course! There are plenty of use cases, including server use cases, where Java is a great choice. But I was reacting to bullen's assertion that "To use anything else on the server is madness.", and to the rather exaggerated

Oh, please. I once worked on a Java-based server at Google that had to answer requests with millisecond latency. In order to achieve this, the server had to block garbage collection most of the time. Periodically, each instance of the serve

Hi. That's me. I'm glad you like it. Unfortunately, melony is right: I've only really been able to focus on the C++ implementation of Cap'n Proto. Some of the others are solid (e.g. Go, Rust), but many are sort of half-b

Do you mean that you got erlang and golang code running in Wasm under Workers, or did you convert the logic to JavaScript?

It's true that, at least at present, Cloudflare Workers is primarily meant to implement web application servers. There are obviously many other ways people use servers which Workers does not yet address. I don't think the post was

Neither side is "right" or "wrong", because this is not actually a binary thing. The two sides are judging the level of risk involved and whether or not that level of risk is acceptable, and they are coming to different

Cloudflare Workers uses isolates, not processes.[0] They start much faster, typically in single-digit milliseconds. In fact, Workers can usually spin up an isolate in parallel with the TLS handshake.[1] After receiving the SNI packet contai

Yeah, it sounds like somehow the system thought you were enterprise. If you see that again please file a ticket, it shouldn't be happening.

Huh? No there isn't. It's completely self-service, no talking to anyone, unless you are going for an enterprise account.
