They did account for underlying health conditions. The control group was matched for relevant clinincal diagnoses, as well as general health factors like BMI and smoking (see "matching variables" section in the paper).

Possibly. But poorer general health is something they explicitly tried to account for with the control group, at least.

That's a fair point. That could inflate the later admission numbers. However, I don't think it can explain the far higher death rate.

Good question to ask, but no, they didn't look at people who tested positive but were admitted for something else: > Individuals were included if they had a hospital episode from 1 January to 31 August 2020 with a primary diagnosis

The full article says it is not only for the ICU, and most were not in the ICU: > 47,780 patients with covid-19 (4,745 admitted to the intensive care unit and 43,035 not requiring admission to the intensive care unit) were included in

Yes, but that seems like a very relevant type of control group. If a person got COVID and ended up in the hospital, and that person wants to know what possible long-term harm that could cause them (that is, compared to had they not gotten C

That's why the study looked at a control group, to try to account for that bias (as the abstract says, the control group was chosen to match "personal and clinical characteristics"). It's always possible they missed a fa

I believe the general plan is to require the headers in all browsers, for SharedArrayBuffer, including Chrome. (But currently, they work regardless there.)

Similar in Go as well: Many things are by value, and it does escape analysis too, allowing a lot of things to not require the GC.

It is still a proposal, but it's one of the proposals most worked on atm, there's a lot of activity.

I think that could have worked. There were ideas to do such a thing, as well as consulting around wasm and other stuff. I'm not sure why none of them were actually tried.

Maybe many users would prefer a desktop app if they use it repeatedly, I agree. But if it's a website you just visit once, it's simpler and safer to just download 10MB of compressed data than to install an app.

You're right that this is not optimized for the Web, but I also think there is a use case for this. Sometimes you just want for code to be able to run at all, even with a sizable download, if it means you don't need to do any port

Even with a vaccine, I'd expect the world to be different than a year ago. There will be long-term changes. Much of Asia went through such changes after SARS, so the world has experience with this. But we can get to something very clos

That number looks accurate, but I'm not sure it's the only thing to look at. First, deaths aren't the only measure. For every death there are many more people that just barely survive after a hospital stay, and data suggests

Technically the unsafe escape hatches exist in those languages, but I think the point is that they are needed less. In Rust you need unsafe to implement some types of graphs, for example, which in GC languages are easy to do without any uns

Very happy to see this too! In Emscripten we've had to emit a handler like that by default, so that test suites don't silently ignore errors. Being able to not emit it will avoid some code size and annoyances users have had.

Indeed, and that may matter in some cases. As I said, it's natural to want a JS parser in Rust. Each language has its own benefits, and Rust's are quite unique.

That would save a few steps (gfortran, dragonegg, llvm-as), so it's definitely worth trying. But note that technically speaking the current approach also uses the LLVM wasm backend (after doing all the above, it uses the LLVM wasm back

You can compile the Lua VM into wasm+JS and run it there, yes. (for example, https://daurnimator.github.io/lua.vm.js/lua.vm.js.html ) Pure wasm doesn't work yet since the VM needs either C++ exceptions or longjmp (

True, good point! Tiered compilation in general does dynamic optimizations, definitely in JavaScript (runtime type collection, etc.) but also to a lesser extent in C# or Java (inlining, etc.). In wasm none of the tiers do dynamic optimizati

True, threads make things more complicated here. (In the context of this link, only wasm MVP is supported, which does not include threads.)

Correct (but the wasm itself cannot observe that).

You can have an infinite loop, sure, but aside from that wasm semantics are precisely defined in a deterministic way (well, except for minor issues with float NaN bits). That is, if a computation terminates, it will always terminate and wit
