The Luau FAQ[1] when they first announced the project mentions that Mike Pall post. I assume they do the computed goto trick for fast interpreter dispatch (or just have some inline assembly now). 1: https://gist.github.com/z

Roblox is essentially a full on game engine and store now, comparable to Unity + Steam with free, automatic cloud hosting and matchmaking. There's a lot of daily users, and the top earners on the platform make multiple millions of do

itch.io fits that. It's still just a two person shop, afaik.

You can also simply have LUKS with a detached header - I know some people that have their header and boot partitions exclusively on a USB, so that it's required to be in possession of the USB key to unlock and boot your computer.

$100M is 1000 people getting paid $100k. $100k isn't a particularly good programmer salary, and is a very high bug bounty salary. From what I've heard, HackerOne/BugCrowd high earners basically just end up spamming as many co

While not a "pure" Duff's Device, Golang apparently does something similar with STOSD for an unrolled memcpy that it can call into at different points. I think it's really cute. https://twitter.com/mayahu

Windows also XORs chunk metadata with a random secret from PEB, at least on some OSes.

Your data being inaccessible without a private key or password is the entire point.

China also has strict restrictions on GPS data, including requiring purposeful obfuscation of coordinates for their GCJ-02 geodetic datum, for national security purposes. They don't want accurate maps made.

Yes, that will happen if you have a multiple page long stack frame. In practice that doesn't happen very often, and the compiler can only insert the probe it needs since the stack frame size is known statically without dynamic `alloca`

A few months ago one of my friends sent a picture of some disassembled x86 they didn't understand: they guessed it was something like `alloca` because it was modifying the stack pointer based on the function parameters, but before it d

User-specific subdomains have their own set of problems too. This is why, for example, GitHub Pages switched their hosting from username.github.com to username.github.io - even with HTTPSOnly cookies, you can still set cookies for other s

Those new articles have basically the same exact conspiracy theory reasoning behind them as the ZeroHedge and friends ones from last week, so this isn't as much of a slam dunk as you make it sound like.

Scott Aaronson has a nice blog post[1] on the same subject. Basically, information is a physical thing in the universe and is just as important as space or energy or time. 1: https://www.scottaaronson.com/blog/?p=3327

There are some very smart research kernels based around only allowing managed, safe code to be ran, so that language security does all the heavy lifting instead of hardware security. The problem then, though, is that every language unsafety

Reading around, Zircon syscalls are non-blocking at the scheduler level. Each syscall still requires a full context switch into kernel mode, though. They can probably do some smart stuff with having each syscall just add stuff to a work que

Re: operational semantics, you can in fact "cheat" and lots of languages do. It's just difficult. Luajit and other tracing JITs optimize away implementation details or use specialized datastructures in the cases where no code

Most of it I'm pretty okay with. The one big pain point is lambda definitions: you have to do `function(x) print(x) end` each time, instead of `\x. print(x)` or something. It sounds small, but with callback heavy or embedded DSL code

Odd anecdote, but my middle school had Encarta 2009 on all the computers and I spent a lot of time going through the historical location free roams finding bad geometry to glitch through walls. I found out-of-bound clips in like 4 of them,
