Not sure, don't have much experience with that. This is a "classic" futamura projection - you write an interpreter and the "magic" turns it into a compiler. I'm not aware of any consumer-grade compiler like tha

"Yes, you can build AOT compilers that beat JITs produced by meta-tracing an interpreter" - not for all the languages. As mentioned below, there is a certain tradeoff associated with JITs - warmup time, memory consumptions etc. Bu

you don't have to use the code, you can (and probably want to) implement the code yourself.

That is the usual "what's easier - starting from scratch or updating existing codebase to newer python". Obviously starting from scratch is more fun, but finishing it to support full python will be a major task that will prob

It makes sense != it makes money. Google does not support cpython either in any meaningful way (that is, someone hired full time to work on cpython for example).

So well, one interesting question as to why this is at the top of hackernews is - do people not know about jython? Jython does exactly that - it compiles python into java (I think it emits bytecode and not Java source, but don't call m

Because for a lot of people in a lot of countries VOC was an oppressive regime. Sure, times were different, but these days you would put them into some sort of crimes against humanity tribunal. They caused a lot of suffering, so in a lot of

PyPy is being update very regularly with 3 releases a year on average. Most of the work however focuses on things our users really want - stability, performance, C extension support, warmup speed, memory consumption - you know the mundane s

The problem that python is facing (and pypy is not solving) is that in order to have a working async library ecosystem, everything , especially the stdlib has to be async aware. This is a far cry right now and I don't see any of the

obviously, but the time of blocking on IO should be the same on all strategies + CPU overhead of doing that

Maybe it's worth noting, maybe not, but this extremely trivial example (e.g. serial.py) gets executed 20x faster just by using pypy which speeds up serial execution. This is more than you would get by any sort of multiprocessing/t

I'm running a small company supporting pypy (baroquesoftware.com). I would love to somehow outsource the bizdev for my projects.

That sounds like a really strange idea to me, can someone explain why does people who used to shoot other people count as a cultural minority, as opposed to say, retired policeman, railway worker or any other group really?

Veterans? What does this word mean in this context? I would expect it to mean a military veteran (this is what wikipedia thinks), but it sounds very weird here. PS. I'm neither living in America nor a native speaker so excuse my lack o

Currently it should work via cpyext (CPython C API legacy infrastructure), but that's gonna be very slow It's possible to write a Cython backend that would generate cffi bindings instead of C, but the work has not been done yet, s

"Vulcan" as a name, really? It's a common word, it's already used by one up and coming technology, please be a little more creative (even VulcanJS or VulcanProof, while not very good, would be heaps better)

Yes, that is fine. I don't want _your_ government, which I can't elect to read my data at all however. A good example is say data mining for giving/not giving visas. It's a much more murky area without a typical due proc

That's how it works ( ) - you still need to make sure in your interpreter that your traces are optimizable by the SIMD optimizer, which is usually relatively fragile, that's just a feature of the optimizations at hand, GCC/

It's of course a bit far fetched, but it would not be particularly hard to convert the interpreter to RPython and get performance/JIT for free

Hi, I'm Maciek, I work on compilers. I would love to know how branch prediction in modern CPUs work, sadly they won't tell me (trade secrets). You should really improve your metaphors.

It's maybe worth noting that while the space is indeed large, it's not actually used for anything much. The human impact of turning of electronic devices is negligable, given there is no cellphone reception anyway. In Karoo (where
