Here's Tom Mueller, the main rocket expert at early SpaceX, describing his experience working with Elon: >And, uh, I’ve seen that hurt us before, I’ve seen that fail, but I’ve also seen— where nobody thought it would work— it was th

I've generally always considered level 2 or 3 autonomy to be a recipe for disaster, humans can't be expected to remain alert and respond quickly when they aren't doing anything. But at the same time the way Tesla autopilot w

Python also has much stronger typing in to converting types of things willy nilly without being instructed to.

In terms of actions I'd agree that the line between conscious volition and instinctual seems pretty blurry. But in terms of experience it seems like there's a pretty sharp line between conscious experiences and subliminal ones wi

Relatively little. Glass and aluminium recycling are a huge boost in energy efficiency compared to the alternative but plastic and paper recycling a pretty marginal. Trying to recycle paper doesn't really have any downsides but tryin

Honestly I'm happy to have plastic production locking up hydrocarbons in a long term stable form to keep it out of the atmosphere where it might otherwise end up.

I've only used Nim but generally if you can use a garbage collected language you should in most cases but there are many cases where you can't, reasonably, and so we have languages like Zig, Rust, C, etc. Unless you're going

Humans are using less data but we throw drastically more compute at the problem during learning.

I'm all for spreading out but prudent stellar husbandry[1] is another potential solution to the problem. [1] https://en.wikipedia.org/wiki/Star_lifting .

Likewise. That's what I was expecting going in rather than Lovecraftian monstrosities like INT_NAN. Plus they're actually something that's supported in some existing ISAs.

Credit card companies acting to limit risk from discretionary enforcement of ambiguous regulations is also sort of political.

I'm not sure about alphabets but I'm pretty sure there are differences in written languages. All languages tend to have roughly the same bitrate when spoken in good conditions. But some languages tend to have simpler sounds spok

I was confused by the lack of little `yx` characters there so looked it up on my own. The 'yu' in りゆ, "riyu" is 86 and the 'yu' in りゅ, "ryu", is 85.

There are lots of options, mostly intelligence agencies of various sorts taking matters into their own hands. Maybe a European or American group which doesn't want Europe bought off or a Russia group which wants total victory rather t

A fishing boat would be a good cover. They're going to be wandering around the Baltic and are expected to have the necessary winches on deck.

The problem is that the technical resources required to pull something like this off don't seem to be all that high. You need a ton or so of explosives which is the hard part, a delayed fuse, a water proof container, a camera and ligh

That's evidence but weak evidence and I think group size is a more likely culprit (we really ought to be homo gregalis rather than homo sapiens ). That means a conflict between a group of sapiens and neanderthalensis is more li

Learning enough C to be able to understand most C you come across is a much, much smaller lift than doing the same with C++. It can be useful later and also give you an understanding of how computers work, at least down to the level of abs

And while we're at it, if a tree falls in a forest with nobody around to hear, does it make a sound? I don't think there's any difference of facts to debate around created or discovered, just semantics.

The V2 decision to go with 4 128 bit vector pipes instead of 2 236 bit ones is a bit odd, maybe due to sharing some of the design with the N2? Or maybe they want to keep things compatible so code can be migrated from a V2 to a smaller core

I think you'll find that modern games use many more cores than they used to since mainstream consoles have all moved to being octa-core for the last two generations and you have things like Vulkan better allowing multi-threaded graphic

Fusion plants also need to absorb the neutrons coming out of the reactor and secure themselves a supply of tritium for their reaction. The most common solution is to do all three with a blanket of molten lithium that can absorb neutrons an

I think haskell does this right. You can make function infix by turning "add a b" into "a `add` b" and you can't overload existing operators but you can make your own and do "a _+ b" or whatever and every

The molecularity of the RISC-V architecture is going to be very appealing for embedded roles like this. That flexibility can be a liability for, say, a desktop operating system but if you've got an embedded system like a space probe w

In terms of carbon let's calculate that. Rotterdam to Shanghai is about 9000 km. The package is 250 g. Container ship transport is about 15 grams of carbon per kilometer per metric ton. So a total emission of 2.25 grams of carbon f

Yeah. If we just reduced our meat consumption by somewhere between 50 and 75% we could feed the remainder off those sources and probably decrease the environmental impact of food production on net, except for cow's methane production.
