It's not that they carry diseases, though that's not great for species that get those diseases, it's that this particular species of mosquito (Aedes aegypti) is really just a pest we bring with us. They aren't native to

Ok. So just invest in one stock. The market never crashes and businesses never go bankrupt.

I'm pretty sure that a "safety check" for social media companies circa 2008 would look like: "Is this likely to harm society in anyway?" "Uh, no. This is some messages and pictures on a website. Look how much m

A conditional move is not guaranteed to be faster than a predictable branch. It varies a lot by microarchitecture. It was just an example. Imagine if you had a store in the else branch. Now optimizing away a store means that load eliminat

Yes, I am assuming the OP considered that in their energy calculations. Solid waste recycling is another issue we desperately need to address to be sustainable.

Also note that the potential for catastrophic meltdown / contamination is proportional to how much fuel you have on board. If you only have ~3 months fuel for a 20MW reactor, then it's not like a 3-mile-island or Chernobyl situati

That's mostly because smaller ships don't need as much power as a sub or carrier. The wattage required for a large container ship is about on par with the reactor for a nuclear sub.

Obviously the non-recyclable solids would be counted separately, and considerable. The average American uses more than their weight in plastic every year, and that is about 80% not recycled.

In the US, spent fuel sits on site in cooling ponds, and has for decades. Spent fuel isn't much, about three cubic meters per year for a big plant. The larger volumes of nuclear waste are from contamination, like accidents, or just thi

The US Navy fields dozens of nuclear vessels. Has since 1954. No meltdowns. Only two ships ever lost, and not due to reactor issues. Subs can go for decades without refueling.

It just exposes how stupid our software stacks are. Everything is driven by "well, maybe they'd want to customize this and that and that and three hundred irrelevant details". When in reality all we ever wanted was to separat

It's not just the direct cost of a branch, it's the downstream costs as well. Removing (or automatically folding branches in a compiler) can lead to optimizations after the branch. E.g. if (foo > 0) { x = 3; } e

Nice work! JIT compilers are a multi-dimensional tradeoff space: memory consumption, startup time, and execution time. I've been experimenting with different ways of visualizing these three dimensions in a tradeoff space. I like the it

Well said. If anything, the geologic record of Earth's history having wild swings between different climates, and not gradual, shouldn't suggest that it's a "robust system", but rather a fragile, sensitive system

Obviously I don't control the PL landscape's decision-making for what level of abstraction they want their compilers to target; that's why I helped create Wasm to put all of that mess into a sandbox so we can move on with a b

Heh, give snark, get snark. Virgil doesn't interoperate with C because ABI is a sticky, ugly, thorny thing. However, I've come to realize that several projects that want to use Wizard, a thing I wrote in Virgil, could do so if Vir

Thanks. Interesting thought. The current Virgil compiler translates from the AST directly to SSA quite early. Specialization, analysis, data representation choices, and lowering all happen on SSA. Translating directly to machine code from t

The syntax-tree driven approach is considerably simpler than Sethi-Ullman, and faster. If you read the blog post, you can see it's based on a 1990 paper that references the 1970 paper that introduced the Sethi-Ullman algorithm. So neit
