the downside is that the go runtime doesn't expect memory reads to page fault, so you may end up with stalls/latency/under-utilization if part of your dataset is paged out (like if…

In Go, overflow is not checked, but it is well-defined in the spec including `programs may rely on "wrap around"`: https://go.dev/ref/spec#Integer_overflow

you are right -- EROI and emissions are different. If you add in things like carbon capture, emissions go down but energy-in goes up. Would it make sense to extract and refine gaso…

Yes they did. Here is one such demo: https://leaky.page/

How did you get COOP/COEP in Github pages? A quick search just now suggested it might be possible with a Service Worker[0], with the caveat that it may only work on _second_ load. …

I think there is a straightforward path to having Browsix generically support the WebAssembly WASI system interface[0] -- any toolchain that emitted binaries targeting that would t…

I'm one of the authors - its so exciting to see continued interest here! The biggest problem with Browsix today stems from Spectre mitigations: Shared Array Buffers aren't enabled …

That's pretty right, with the addition that other things can target Browsix (like the gopherjs toolchain). Emscripten provides default implementations of a bunch of syscalls (and e…

(author here) Without something like Browsix you have to make a choice: find a JavaScript library or implement the functionality you want to run client side, or run existing Unix p…

(one of the authors here) it was written in Typescript from the start! Typescript eliminated a bunch of type confusion errors when developing the kernel, although the need to marsh…

(444) 444-4444 also works

Can you compare `tcmalloc` to e.g. tcmalloc dynamically loaded, or jemalloc specified with Bazel's malloc option? It is unclear from the post whether the wins are improvements from…

WASI provides a cross platform definition of "system calls" ( https://github.com/WebAssembly/WASI/blob/master/design/WASI-... ), so that you could write a program, compile it for w…

(I'm one of the authors of Not So Fast) In the paper we build on previous work from our group, Browsix ( https://browsix.org ) to provide a similar level of abstractions to WASI (t…

Well, there are 2 sides to increasing page sizes. If you can fit more objects on a page, there is a higher chance of collision at a given occupancy %, reducing the effectiveness of…

This sounds right - that line was written before Rust used the system allocator by default. Will update, although I'm still itching to write a GlobalAlloc implementation.

Hi! I'm one of the authors -- thanks so much! We thought similarly about cache performance, but weren't able to find specific examples (most of the slow benchmarks we dug into were…

It isn't the only way to handle concurrency, but they are the only primitives that can be used to port existing code (C/C++/Rust/etc) into the browser sandbox without killing perfo…

GopherJS is _not_ an emulator. Saying that it emulates a 32-bit environment means that `int` (which is architecture-specific in Go) is 4 bytes (compared to 8-bytes on amd64), and m…

Please take a look at the contributions in the paper at the end of the introduction. The JVM uses operating system abstractions (like a file system, threads, and synchronous APIs) …

Doppio relies heavily on the Javascript object model, the asm.js subset of Javascript isn't very relevant.

yes -- it implements Java objects on top of Javascript objects.

I think the most compelling use case is running legacy code in the browser (and in applications like Atom and Visual Studio Code) - like our Latex example. Another good use case ar…

JSLinux is a tremendous feat of engineering. If you want to run realistic programs in the browser (and not just technology demos), WebAssembly, asm.js, and compilation to JavaScrip…

Yes! GopherJS has been amazing to work with. The majority of our changes ( https://github.com/bpowers/browsix-gopherjs ) amount to an alternative implementation of the compiler/nat…
