Most people are worried about the reactor transitioning to an open loop against the wishes of the maintainers.

But that’s good info, thanks. Molten salt still has to heat transfer to steam because we don’t have any thermovoltaics in the 50% efficient range.

I think I now understand that most of the heat comes from absorbing neutrons, which don’t like to generate electricity (vs betavoltaics and gammavoltaics). And any device inside the pressure vessel would be altered by those neutrons, need to be accounted for as another source of decaying particles, and need to be replaced.

And/Or, you’d want a completely different reaction and then need a neutron generator capable of running continuously.

That about right?
CS 333 Assignment 1: s/ed/grep/
No, but you're defining a unit here; I'd expect people to put in values as 0..100 with unit being percent. So if a person puts in 20, and you'll want to multiply it by 3, you'd not expect 60 as end result; you'd expect 60% which is 0.6

You're still raising valid point with the ambiguity - if I were to see a variable named `population_percentage = 0.01` I'd still need to ask the author if the intended value here is 1 or 0.01, which I'd say disqualifies this naming.
The way these work is pretty interesting. Rather than combusting a fuel and an oxidizer as in a typical rocket, these use hydrogen peroxide that is exposed to a platinum catalyst, which causes the rapid decomposition of h202 into h20 and 02, which is then expelled through the rocket nozzle, generating thrust. This greatly simplifies the design of the rocket engine.

Like, at what point is well enough alone for a headline that was already succinct, descriptive and well formed and why keep coming back an hour later-after presumably more people have seen the article and may want to come back later-to change the title again?

@dang (if you come across this): is HN remotely interested, for the curiosity satiating edification of the community-if no other reason-in sharing the decision calculus for these kinds of title edits?
Interesting. But it's circular reasoning isn't it? "there were less people, so less innovation. Then there were more people, so more innovation. But now there's more people, but less innovation, so it must be a dark age" doesn't really work as a self-evident statement.

You could make an argument that innovation follows the money. The innovation boom of the late 20th century correlates with the music industry profit boom of the same priod. Now there's less money being made, there's less innovation.

Also, you could probably chart the risk-taking of the music industry. They started off not knowing what the hell anyone wanted, so produced weird shit. Then they got hit by waves of disruption. Then they got a grip on it all and stopped taking risks. Which is where we are: stuff that sounds different doesn't get published.

Except, of course, that we have people self-publishing now. There probably is completely freaky weird awesome shit being made, but we don't hear it because discovery is hard in such a huge sea of music.

Interesting stuff.
For that growth chart to materialize you have to be lucky. And nothing brings luck down on someone like rich parents.
I clicked on a few and they all turned out to be tutorials for beginners.

I would use it if it had a filter for "How long have you been programming:"

[ ] Never
[ ] 1 Year
[ ] 3 Years
[ ] Over 10 years

Then I would tick the "Over 10 years" option and hope to find channels that update me on the latest developments. While somebody else would select the "Never" option and will find beginner tutorials.
Covid aside, which is self inflicted, I highly disagree.

FWIW, the US claims that they no longer give these pills to any military personnel. [0]

as for why the pilots in particular, my (fairly uneducated) guess is that pilots inherently have knowledge of more sensitive information than a typical infantry person. while the soldier probably only has knowledge of local troop movements that will be stale in a few days (most US infantry standard procedures and equipment details are public knowledge), the pilot may know classified information about the aircraft they are flying.

Apple has something like this for their new iOS device setup. I don’t think it’s to encode larger amounts of data, but for security they have this circle that constantly changes shape (see around 0:50 in this video for a demo: https://youtu.be/iE03ypWD5xs). I don’t know for sure how it works, but my first thought was a constantly changing QR-like code.
It is possible (and in fact, expected) of companies that take these kinds of pledges to have a baseline set of human rights that most people (or at least most people on Apple's board) will agree on, even if there is ambiguity around the edges.

The alternative is saying, "we'll stand for this thing that we refuse to define in even vague terms, and as a result it will be impossible for anyone to evaluate whether or not we're succeeding, or even making progress."

If Apple can't determine even in broad terms what is and isn't a rights violation, then their declaration is meaningless. They don't need to decide for everyone, and not everyone needs to agree with them -- it's fine for other people and companies to come up with their own criteria. But Apple has to at least some internal idea of what they mean when they say they stand for something, otherwise it will be impossible for them to build real policies around the declaration.

And some of this honestly isn't that controversial among scholars. As an analogy, if I commit to avoiding stocking unhealthy products in my store, I don't need to know for certain whether or not coffee is healthy in order to say Cadbury Eggs are not -- pretty much everyone agrees on that. In the same way, we don't really need to debate whether or not healthcare is a human right to understand that forced abortions, forced monitoring and 'reeducation', and concentration camps for Uighurs are violations of their human rights.

I think a lot of educational Youtube channels aren't that great in actually teaching you anything. What they are great at is sparking the interest and planting the seed for your own work. At least my experience is that actually doing things is how I learn them. Youtube can be a great springboard for that.

Things to look out for: a person you like and who has enthusiasm and knowledge.

For example EEVBlog Youtube channel was a great way to get into electronics. It's very surface level, and you have to do the learning yourself, but the surface level of what you get is a broad overview which you can choose how to deepen and iterate on. Get that surface level from Youtube, so that you can understand the whole picture, then go through the parts yourself.

For just learning web efficiently, things like https://fullstackopen.com/en/ seem a lot better.

I get so frustrated using reddit on mobile browsers because the reddit app popups or dark patterns that stop me from reading a complete post or the comments in the post are so antagonistic.

I don't know how much time I've wasted trying to get "Read more" to take me to the right spot just to find out I'd read the entire thing or there was one asinine comment in the entire thread it was hiding from me.

The new reddit ux is so bad but I don't use the site enough anymore to dedicate myself to a full app, and those have all of their own frustrations. It'd be nice if the default browser experience was the native and "clean" one, not the worst one.

> This also reads a little weird. The author is obviously well versed in history and the progression of civilisation, and as such, must be aware that we’ve always moved in a progressive direction. Sure it sometimes takes a few life times, but we’ve never moved permanently backwards before, so it would be rather strange if we started doing that now.

As a counterpoint, I'd read the essay "The Whig Interpretation of History"(1931). Her criticizes the notion of interpreting history as a story of progress.

To be fair, Coal Chamber and Sublime are "objectively awful" :D

Winamp was so slick. Lightweight, did one thing very well.

A modern version would probably be built on Electron, be a 500Mb download & require 8Gb RAM to just run (12Gb required if you want to change the skin).

I long for the days where things weren't so bloated.
Honestly makes a lot of sense.

Might be possible do do it as a ram jet too, that would get you a lot of efficiency upsides.
Typical jet engines probably wouldn't work well however due to force but you get a fuel feed upside from the centrifugal force.
Isn't this fuel rather toxic in case of accident?

In Elm (and many other languages, I assume, I'm just most familiar with Elm) there's a pattern called "opaque data type". [0] You make a file that contains the type and its constructor but you don't export the constructor. You only export the getter and setter methods. This ensures that if you properly police the methods of that one short file, everywhere else in your program that the type is used is guaranteed by the type system to have a number between zero and one.

-- BetweenZeroAndOne.elm

module BetweenZeroAndOne exposing (get, set)

type BetweenZeroAndOne
= BetweenZeroAndOne Float

set : Float -> BetweenZeroAndOne
set value = BetweenZeroAndOne (Basics.clamp 0.0 1.0 value)

get : BetweenZeroAndOne -> Float
get (BetweenZeroAndOne value) = value

I wonder if there is a geopolitical angle considering all the shit going on in Minsk now. With that said I think it's disgusting for a company like upwork to terminate a user without reason.

In a normal helicopter, the helicopter is exerting a force on the rotors and thus feels an equal and opposite force that needs to be countered, either by a tail rotor or a counter-rotating rotor. This helicopter doesn't do that. If anything I'd think it might need a tail rotor to stop it from spinning in the same direction as the rotor, but I guess friction between the helicopter body and the rotor is low enough that this isn't a serious concern.

(The linked youtube video shows a version of this helicopter that does have such a tail rotor, though positioned closer to the helicopter than it might normally be.)

At least in the previous decade, and even at that time in other parts of UK science, I don't think there was a "software priesthood". It probably invaded astronomy and HEP earlier than elsewhere, and to some extent now resides in Research Software Engineering. The first OS on the nuclear structure interactive graphics system was written by a Birmingham physicist, for instance. I wrote analysis software as necessary (and read up on software engineering as well as the other techniques needed for the research, like electronics and high vacuum systems). The UK Computational Computing Projects were run by scientists who did the work, and you could get Fellow of the Royal Society-level help (though the two mainstays of CCP4 only got the title much later).

I don't know where this free software elitism is prevalent, as someone involved with it in research since before the term became necessary. I could appreciate the UHH, by the way, from a time when Unix was largely not free software.

Funny, I agree with him because of things like Covid being self-inflicted. We're so unable, as a species, to avoid even known risks (yes, we've known about the risk of new Coronaviruses since SARS), prepare for them, or deal with them when they've actually occurred. Even now, a not insignificant part of the US population thinks Covid is a hoax. Or that climate change is a hoax. We're reaching a point where catastrophic failure is just a stone's throw away, and we're already seeing the system buckle (rise of the Republican's hold over Congress, the rise of Trump, the rise of far right activists across Europe, growing environmental issues causing things like surges of refugees and civil war, unrest across the globe, etc.). It's only going to get worse from here as problems go unsolved and people's suffering grows.
