> I haven't thought about C in years ... Im going to stick with my VM over here and call it a day. What's your VM written in?

  Probably not C regardless. How many widely used VMs are in C? Python is about it, right?
  • Kamq 4y ago
    Java's? Or at least it used to be.

      Openjdk seems to be more c++ than c according to GitHub anyway. In particular the "interesting" stuff (so hotspot) looks to be all c++.

        It started as C. It’s interesting to watch people post comments, as though C vs C++ makes the distinction in “safety” in a code base. The take away I’m getting is most have programmed in neither.

          These people are just regurgitating HN memes and then flailing when someone prods a bit deeper. C is basically the Donald Trump of HN. All rational thought goes out the door at the mere mention. In fact, you’re socially rewarded for joining the idiot mob.

  Safe Rust. https://deno.land/ https://deno.land/
  • asguy 4y ago
    Except for most of deno that's written in Unsafe C++. https://v8.dev/ https://v8.dev/

      A JS runtime is a lot more than the core engine, or else nodejs is just a thin wrapper over V8 as well, which is obviously absurd. So without a count of the source lines for each language's portion of the implementation (very rough but acceptable first approximation of how much is implemented in each), you can't claim C++ is doing most of the heavy lifting and be taken seriously. PS. the worst C++ code is still a hell of a lot more safe than the best C code. This is easy to convince yourself of by noting that C++ mostly supersets C and only deviates to add more safety and static checking, not less. So it's a strict improvment over C, not by a lot, but an improvment nonetheless. Here are other examples for VMs not written in any of those 2 braindead languages though: [1] Bun : JS runtime in Zig. https://bun.sh/ https://bun.sh/ [2] Squeak : Smalltalk VM written in Smalltalk. http://www.vpri.org/pdf/tr1997001_backto.pdf http://www.vpri.org/pdf/tr1997001_backto.pdf [3] PyPy : Not actually a single VM but an entire framework\toolchain to write VMs, most famous of which is one for Python. The language used to write VMs for the framework is a subset of python called Rpython. https://doc.pypy.org/en/latest/ https://doc.pypy.org/en/latest/ [4] Maxine Virtual Machine : a JVM written entirely in Java. It's not the only one. https://en.wikipedia.org/wiki/Maxine_Virtual_Machine https://en.wikipedia.org/wiki/Maxine_Virtual_Machine ; https://news.ycombinator.com/item?id=15733645 https://news.ycombinator.com/item?id=15733645 Modern VM research is far beyond the 50 year old assembler that thinks itself a programming language. The future is here, just not very evenly distributed.

          The only one coping here is that who doesn't understand VMs and language research enough and retreats into childish "it was just a joke lol" remarks when out of their depth. Incidentally, I write all 3 of C, C++ and x86 assembly, which is why I understand how braindead and unfit for human usage they are.
