What is a former q3 champion doing these days? I'm genuinely curious. Since you are on hacker news I assume you do something with software. Any skills that you picked up back then that are useful today?

Firmware is using cache as RAM (e.g. https://www.coreboot.org/images/6/6c/LBCar.pdf ) to do early init, like DRAM training. I guess later things in the boot chain rely on DRAM being set up probably though.

Probably a OpenJDK Zero VM build. That's a configuration without JIT or template interpreter, but a "plain" C++ switch dispatch interpreter that requires no runtime code generation.

Sure, but neither javac (the Java to bytecode compiler) or HotSpot are doing that. The former tries to preserve as much as possible, and for the latter interprocedure analysis is too costly at run-time.

Thanks for the context! What's the difference between the stage2 and stage3 binary? Does stage1 produce different binaries for the same input compared to stage2/stage3?

GraalVM will have a stable release that includes Apple Silicon support next week. Glad to see the snapshot did the job for you though :-)

I'm new to mechanical and split keyboards, but so far the moonlander has been great. Well, in the beginning it was a bit of a learning curve, but coming from the ergodox that shouldn't be an issue for you. Not being wireless is th

My pessimism tends to agree with you. OTOH social distancing and wearing masks has shown recently that (most) people are fine with changing their behavior, if necessary.

Targeting a stack machine is much easier when writing a compiler for the first time, but real-world machines are generally register based. In general this is true, here however, we are targeting LLMV IR which is register based with infin

`jaotc` integrates with the HotSpot VM, while Substrate VM provides its own runtime (GC etc.) and intentionally supports only a subset of the JVM features. FWIW, both use Graal as a compiler.

that's most likely intentional, I'm sure Oracle has a lot of lawyers to look over this kind of stuff ;-)

With Substrate VM you get way faster startup for your Truffle language and potentially overall less dynamic footprint. Graal VM is based on HotSpot, which is sort of "bloated" for the specific use case that Truffle has.

This is huge, congrats to the team! I hope it helps Substrate VM to get better adoption outside of Oracle.

Ideally, an application doesn't have to choose, but the runtime uses some good defaults. For example, let's have a look at the HotSpot JVM: A Java method first gets executed in the interpreter, then, if it's hot enough it wil
