In most situations, the allocation size is a constant and bumping upwards can be done without an overflow check because the region cannot be close enough to the upper part of memory to wrap around. I'm surprised that there was no discu

I turned it off more than a year ago and then it started nagging me to turn it back on, to the point it would not even show me my lists without enabling it. Dark pattern.

Well put. And everyone plays along. When the big, popular apps become idiocracized, then the smaller apps follow suit. It really seems that there's a race-to-the-bottom effect going on. Case in point: Guitar tuner apps. Back in 2005 a

Ha, I read Ayn Rand 20 years ago, before the last stages of anarcho-capitalism revealed how vapid and destructive that non-philosophy to be. I don't feel entitled to anything, but I do think you get what you pay for. And America has be

In other words, all hail our new corporate thought police. The market can do no wrong, right? Sick of getting squashed by big tech? Feel like the market (of billions of dollars of ad money) didn't punish them hard enough? Just launch y

It's a shock to me that the "free speech absolutists" running X can't be bothered to even put down their policy in writing. Actually, it's not a shock. They don't want it because they're not free speech

Huh? This requires the actual thought police --you know, the unaccountable social media platforms--to publish their rules. Or would you rather they just continuing applying their own unaccountable and secret moderation with no consequences

Virgil compiles to Wasm and brings its own GC as well, and the runtime is on the order of about 4KB. The GC is a simple semi-space copying collector and the compiler prunes away dead code from libraries, so binaries are pretty small. So ove

Even then, there could have been many breeding pairs of humans that were alive and operating and their descendants just did not survive until today. As I wrote in my comment, it doesn't actually say that the population was 1280 indiv

No, it doesn't mean that. The bottleneck doesn't say anything about how many people were alive then, just how many contributed DNA surviving until present day. There could have been millions of individuals whose offspring eventual

Headline is misleading. The existence of a population bottleneck of approximately 1200 individuals does not imply that humans almost went extinct. It doesn't say anything about the size of the population before or after that bottlene

Really awesome work! If the authors happen to drop by, I'd be curious if some of the work in their pipeline might be able to help for other types of GUI applications with Wasm. I'm also very curious to see what role, if any the Wa

Great to see more focus on observability for Wasm now. This was a major impetus and still a major goal of the Wizard Research Engine, which has engine-level hooks that allow programmable instrumentation.

Header files in C/C++ boil down to textual inclusion. They generally end up with such complicated directive logic that a compiler can't reasonably pre-compile or even pre-parse them and get the semantics right. Large projects ten

The goal of lowering to binary at 0.1 million lines/sec isn't very ambitious. Virgil bootstraps its 59,000 line compiler in 400 milliseconds, which is over that number, and it does whole program reachability and optimization. On t
