While FUSE doesn't work directly, there are userspace filesystem implementations for Windows. Dokany¹ even implements most of the FUSE API. 1. https://github.com/dokan-dev/dokany

Sadly it's dead now. In a cruel twist of fate, Intel killed it off shortly before we found out about all the speculative execution attacks and found that everything else is horrifically vulnerable.

Itanium does this automatically. You declare what registers you're using in the the function prologue and it handles popping/pushing/renaming. No register window exceptions too.

Ah, duh, you're right. I forgot $() is bash syntax and not the Ruby syntax for running an external command. Thanks, and yikes.

Somehow people in the ESlint thread were defending the fact that NPM seems totally uninterested in this. Yes, it doesn't solve all the problems and yes you still have to determine who to trust, but at least it makes it POSSIBLE to tr

Hence why NPM exists in the first place.

In case anyone is wondering about why this project puts so much importance on things being inlineable, GPUs often don't support function calls or have an extremely shallow return stack. In this way it reminds me of http://fu

Frankly, to me the specifics of the syntax are not nearly as important as what the language does. This: > Abstraction by heap allocation is a dead end. It works moderately well on the current generation of computers where CPU is still th

You make good points about package signing. It's not a trivial problem. Fortunately it's a solved one. There are package managers (pacman, nuget, rpm, etc) that do this. Yes, maintaining a web of trust is required. Nobody said oth

No, that's a fine idea and would've prevented this problem. The build reflecting the repo is a very sane thing to do. Unfortunately NPM is run and used by morons so that'll not happen.

I mean, in the strict formulation of "transistor counts doubling every 2 years" it's been dead since like 2015 if not earlier. That said, the "death of Moore's law" is kind of this memetic doomsday device that

It's pretty clear that Microsoft really took a close look at the specs when developing Edge, which is really nice. It also has the benefit of being the newest of the major engines.

Zig is nice. It's the type of programming language I'd write if I didn't want to do anything novel and just wanted to make something a little better than what's out there currently. It's not the future, but it'

I figured the use-case here was MADV_WILLNEED, which is what PrefetchVirtualMemory is for. VirtualAlloc flags would be for things like reserving virtual pages without committing them. There's no single API on Windows that does the myri

by PeCaN 8y ago
Windows 8 and later has PrefetchVirtualMemory[1]. Before that your best bet is to get a little hacky and try reading the file asynchronously to get it in the cache (Windows caches files pretty aggressively, so this more or less works). [1]

It's still supported by OpenBSD and QNX as well. It's actually not really dead and is moderately popular in embedded systems. Also, the patents are expiring and the http://j-core.org/ project is working on an open

by PeCaN 8y ago
Ada can do this conveniently and it can be nice for efficiency and embedded systems (which may not allow heap allocation). It would be nice to see the same feature in Rust.

Dynamic types are very JIT-able. The first JITs ever were for a dynamically-typed language (Smalltalk).

Don't know yet. IBM has a CPython-based JIT using OMR but it hasn't been publicly released yet. Ruby OMR is a little more public and from what I can tell gets about a 30%-200% speedup. They basically just stapled OMR onto the regu

OMR is amazing. It's essentially IBM's J9 virtual machine, with all the man-decades of effort that went into that. However, if you're writing your own JIT language and you've never written one before, you probably want t

It's actually extremely easy, particularly if you're familiar with Prolog (the core algorithm is a couple lines in Prolog, so knowing how that works is useful for implementing it in other languages). I suspect the lack of statical

I was surprised nobody mentioned mruby in this thread until now. It's tiny, super easy to embed, and Ruby is a fun language. Also, mruby has the benefit over most of these other languages of having had a recent thorough security audit[

Always cool to see ATS in the wild. Higher-order functions on an 8-bit CPU makes me happy. :D

I hate function call syntax with parens. It makes code much more difficult to read and, if it supports calling functions, calling functions with args is harder than it should be.
