Whereas killing someone for stealing your phone will come with no trauma whatsoever?

It means they'd avoid an article on the benefits of smoking if it's posted by a company selling cigarettes.

The dummies phrasing is my own, and I stand by it - I simply find the CFG way of thinking much easier to reason about than the SoN way, and I find myself falling back into it no ma…

(disclaimer: current V8 team member replying to senior ex-V8 team member) I'd say there were a lot more things problematic in practice with SoN than not relaxing effect edges enoug…

Be careful to check whether you're in a glass house before throwing stones - "layoff" used to mean a temporary release from employment for seasonal labour before it meant a permane…

You can't currently "compile JS to Wasm", you can compile a JS engine (likely written in C++) to Wasm and run JS inside that (almost certainly at lower speed). So instead of "no mo…

The complex parts of JavaScript are the semantics, not the syntax. You could reasonably easily spec a bytecode for JS to get rid of the syntax part, but nothing would change in the…

I guess in this system, you'd also type lowercase letters by holding shift?

rr ( https://rr-project.org/ ) and memory watchpoints are a godsend when it comes to analysing heap corruptions.

The signed length fields pre-date the sandbox, and at that point being able to corrupt the string length meant you already had an OOB write primitive and didn't need to get one via…

I said it "protects" against bugs, not that it "removes" them. The Truffle architecture removes mismatches between JIT and interpreted code (when it doesn't have bugs itself, which…

The V8 sandbox doesn't just protect against JIT issues, it also protects against logical issues in the runtime and object model.

Ok, person with anonymous account name.

It certainly disproves that it's a pattern without exceptions, and therefore invalidates or at least questions the idea that every instance of up and down (like which way up north …

More likely in feet than metres.

Are you down for looking for counterexamples? Do you want to get to the bottom of why people cherry pick examples for their argument? Is this what you want to base your argument on…

The Dual-Kawase blur sounds like a texture-sampling-efficient variant of building a Gaussian pyramid ( https://en.wikipedia.org/wiki/Pyramid_(image_processing) )?

"The data presented in this article is sourced from the United Nations International Migration Stock for the year 2020."

It's not - the general path is a bailout for the fast path which continues where the fast path stopped, so you don't have to check the whole object for fastness (and you get the fa…

What can't though?

Fast code isn't a quantum effect, it doesn't wait for a measurement to wave collapse into being fast. The _assertion_ that a certain piece of code is fast probably requires a measu…

I once destroyed an entire small enemy camp in a 5e campaign by causing an avalanche using Create Water -- arguing that the 10 gallons of water I create would be a whole lot of sno…

And yet here you are saying it.

Something I find fascinating is that we know that P != EXPTIME, and that P <= NP <= EXPTIME, but have managed to prove neither P != NP nor NP != EXPTIME. NP has to be somewhere bet…

The eval thing is listed as a potential performance cost, but it's actually super important for performance, because it allows the parser to statically know that sloppy eval is nev…
