Another big problem is leaking and boil-off. There's a reason that no space mission longer than days uses LH2 as its propellant; it just doesn't last long enough, because of boil-off caused by solar heating and the hydrogen actually leaking out through the fuel tank. Insulation isn't 100% effective and it's hot in space near the Sun where we are, certainly much hotter than the 20K boiling temperature of LH2. Even if the insulation is 99% effective that's still significant heat flow at a temperature higher than 20K, and you have boil-off.

So, yeah, it's fine for uses in stages to orbit, and it was even fine to use for the Apollo missions because it was only 3 days there, but anything longer than that and it's increasingly not suitable.

> In general it seems like density should matter less than mass

Mass is already incorporated into Isp. So, for the same total mass of propellant being exhausted at the same velocity, you definitely would rather have the denser fuel so that your fuel tank can be smaller and thus lighter.

I imagine everyone who drinks coffee does so because they like it... else they wouldn't drink it. Some enjoy the flavor of straight coffee more than others, sure.

I don't really understand how getting into coffee as a hobby makes it any less of a drug. You're still consuming caffeine. There's just as much of a hobby scene around marijuana; hobbyists are still consuming THC.
What lawsuits. They are well within their right to remove whatever they want. Maybe not everyone agrees thats how it should be, but thats how it is.

It's a clash of cultures and a power struggle. The "hacker" style people feel that the rug is being pulled out under them and a corporate-style top-down leadership is dictating how they should interact.

Generally, hacker culture is very much against top-down authority and prefers organically grown, community-driven, distributed approach.

It's no surprise that the facebookization of SO is not welcome by them.

The same thing is happening on Reddit, Twitter and other platforms. The Internet is finishing the transformation from Napster, IRC, torrents, enthusiast content and hacking to corporate-sanitized marketing-compatible monetized influencer space. The new focus is engagement metrics, ad placement, brand protection etc. Traditional mainstream TV content is now taking up larger and larger share of online space, same with traditional newspapers.

You have to take this larger context into account. If these people could shut down the web, they'd do it in a whim and forbid anonymity and reverse everything that made the web so popular and drive everything back to cable TV but with likes, followers and shares, of course with a real name policy, with phone and ID confirmation.

This is not about the Thanks button, but a disregard for the community, and top-down dictates.
> As the linked article points out, employers often look for the degree, but do not believe it is much of an indicator of quality and don't expect new grads to walk in the door with the needed skills. As a former recruiter I think that sentiment is pretty spot on. I don't think I ever asked a candidate about the details of their education. It was just never relevant in comparison to their experience.

Universities aren't tech schools; their purpose is not job training.

My understanding is that employers used to be comfortable providing pretty extensive job training, and they probably should start doing that again. IMHO, it's wishful thinking to expect any kind of school to produce new grads that can "walk in the door with the needed skills," especially in a field as diverse as software engineering.
I think if you've reached the point where you're committing genocide, you're well past the point where your intentions matter. There really isn't much else worth talking about if you're committing genocide, because genocide is just so much worse than almost everything.

Censorship is bad, but I think at the level of censorship we're discussing, it's not so bad that we can't reasonably note that bigotry is also bad. Someone promoting censorship of bigots is just a censor; someone promoting censorship in favor of bigots is both a censor and a bigot. Two wrongs are worse than one.

It looks like this is not an ARM core, but a Fujitsu implementation of the Arm v8-A instruction set and Fujitsu-developed Scaleable Vector Extension. Most likely the latter is doing all the heavy lifting.

https://www.fujitsu.com/global/about/resources/news/press-re...

>A64FX is the world's first CPU to adopt the Scalable Vector Extension (SVE), an extension of Armv8-A instruction set architecture for supercomputers. Building on over 60 years' worth of Fujitsu-developed microarchitecture, this chip offers peak performance of over 2.7 TFLOPS, demonstrating superior HPC and AI performance.
It sounds exactly like a late night infomercial.
But there's a lot of cases where there's data about someone that is not owned by them. e.g. If I go into a store and am recorded on the CCTV, the store still owns that video, even if it is about me. This could be pretty similar to the way that if someone uses Facebook and clicks on something, Facebook would own the log which recorded this.

In other cases the data that users upload to websites is definitely owned by them. e.g. If I take a picture on my phone, and then later upload it to Facebook, the photo is still owned by me. However, for any site that allows users to upload photos, it will be part of the terms of service that the users give the site a license to display the photo.
India has news channels castigating the govt everyday. Wire, NDTV are 2 examples.

Attempts to bring a constitutional amendment (NRC, CAA) which discriminated against 1 religious community was vehemently opposed and stopped. People took to the streets.

How many political parties does the beacon of democracy in the world have ? How does such an example of democracy end up choosing between a tyrant and a senile ?

Authoritarianism and right wing leaders are on the rise around the world. India is also fighting the same challenges.

Poverty and lack of education are primary reasons of corruption, India is growing organically like a democracy of its size should, fighting the challenges it has.

The only reason India has a voice against China is because of its Nuclear capability, had it relied on the goodwill of the west, India would be bowing to China like other ASEAN countries.

China is at par with US today because of over dependence of the latter on the former. The US can continue to enable a authoritarian, non democratic power, or support a country which believes in its democratic values in becoming its ally against China and stabilize the world.

What do you think will happen to democratic values of the world when China reigns supreme ? (A Uyghur would like to say Hi!)
This is another misunderstanding/misconnection. "kernel_task" is used to report "missing" CPU time so the CPU usage accounting remains consistent even when the CPU is throttled. That does not mean either the kernel or userland have any input to the thermal throttling functions.

There's also multiple levels of protection and throttling. At the lowest level, various ICs on the board (e.g. power regulators) will turn themselves off if they overheat. Somewhere above that, firmware will definitely exert /some/ control, to cover odd situations like the machine hanging while booting. Above that, the kernel or userspace can add another layer — but like each of the layers before, that layer can only lower the limits further.

Having thermal management in userland (and nowhere else) would be legal suicide. Imagine the lawsuits from people accidentally burning their legs...

> Yeah. That's insanity. Is that backed up by any study?

Sure it is. In general this kind of data is hard to acquire because the police rarely stop working. When they do though, the results are fairly clear [0]. This study was made after a "strike" by the police. The study attempts to account for under-reporting due to this fact.

Please note that just because _some_ crime is caused by police doesn't mean _all_ is.

> There is no country on earth without a police department.

Something about appeal to tradition. Anyway, as you might know police departments are a very new thing. Policing, in its current form, has existed for <200 years, founded under what is known as the Peelian principles [1]. Principles my previous paragraph demonstrates to have been violated by the police departments.

> PTSD in soldiers that weren't even casualties

The two of us are obviously coming from two very different perspectives. I have a hard time having sympathy for the soldiers who fought in Iraq and I think I'll have a hard time convincing you to feel otherwise.

'Universal Search' seems to be a clone of Spotlight, now on iPad. Interesting.
That's really cool and I didn't think of that. I just wanted clarification: that means you train the agent without the deterministic solution and your "validation/test" (I'm not sure what those phases are called in unsupervised learning) sets are done without the deterministic solution.
>people get radicalized slowly - you start with the softer sound bites, the ones where they have a lot more wiggle room to claim you don't mean this other thing. And as people start to agree with that idea, you move in with one that pushes the boundaries a bit farther. Keep repeating this process, and someone ends up embedded in the extreme forms of hate.

Why does this happen in one direction but not the other? A radical sees something slightly less hardcore. Is influenced. Sees more non-hateful content. Slowly moves away from radicalism and towards the center. Why doesn't that happen equally as the other way around? Should be a balance there, right?

Really, your whole point is essentially stating that these ideas that you hate are more convincing than the ideas you believe in. You don't think you can consistently win the war of ideas via argumentation so, since you obviously are right and your ideas are best, that justifies using power to simply suppress other people's thoughts and words.

All of this rests on your 100% certainty of being correct. Once you admit any level of uncertainty, which you must, your whole approach collapses.

Why do you get to do it to them, but they don't get to do it to you? It's because you think you're 100% right. Of course they think the same about themselves, though, so you're claiming you have some special moral position in the universe that they don't. you stand above them; you have the right to judgment on them but they don't have the right to judgment on you.

Nothing justifies that. The only real differential is that you have the power to silence them and they don't have the power to silence you, and so you're going to use that power and screw equal rights.

>something that you know is harmful and dangerous to human lives

You keep saying these things as though they're absolute facts. They're not facts. That's your opinion. Others' opinion is the opposite - to them all of your beliefs are harmful and dangerous to human lives. And you're walled yourself in so you don't understand the reasoning, and end up thinking it's just inchoate meaningless 'hate' that you're opposed to. You're ignorant of ideas outside your filter bubble, and use the strawman images of opposition you've invented to justify enforcing that filter bubble on others using power.

I don't have a lot of experience with C++ and even I know that the most likely cause of that error is not having the linker configured correctly. It's probably something simple like a common library not being linked in.
I just tested it and any post deleted by the user has [deleted] for both the post body and username. Posts removed by mods will have [removed] for the post body but will still leave the username untouched. A post needs to be both deleted and removed for it to appear like that specific example with [removed] for the body and [deleted] for the username.
it's a bit annoying that they used their own proprietary format, which they will probably never open to others.
Interesting article and I agree with some things being said, but talking about Hydrogen power as an opportunity that Americans have failed to capitalize on is ludicrous. Sure if we had a pile of Hydrogen to burn it’d burn clean. But all the Hydrogen immediately accessible to us on earth is locked up in molecules that cost more energy to break apart than it’s worth eg electrolysis of h2o. Perhaps Hydrogen can be used as as energy storage but practicalities related to the difficulty of building containment systems capable of storing it, the phenomenon of Hydrogen embrittlement of metal, etc. place it low on the list of energy storage technologies I’d bet on.
Bias in machine learning: We can do better
> You're saying they should face backlash from government regulators not from users

I never said that. But it's probably a good idea to have some sort of oversight for a massive platform that censors and manipulates discussion of millions of people. You may think their policies are totally justified and correct (they aren't), but the specific opinions they choose to promote may change to something you are against.

> If there's a big user backlash, those users are already free to move to whatever site they want, or make their own.

Yes, they are also free to shit on the website and point out it's flaws.

> So if a site wanted to enforce some sort of "family friendly" policy, you could simply bomb them with truly illegal shit instead and get them in trouble with the regulators for not being able to keep up as they would be liable for that, since they aren't a "anything legal goes" platform.

Trolling is not illegal, it's not even a specific thing. It's a very ambiguous term used to describe 'comment's that make me feel bad'. Trolling and posting illegal shit is completely different, sure ban illegal stuff - you kind of have to, but don't use 'trolling' as an excuse to ban stuff you disagree with.
I think Apple realizes that instantly forwarding all messages to mentioned individuals would be pretty stupid.
> 'Far-left content' and 'hateful content' are not mutually exclusive. Quite the opposite, really.

I wouldn't characterize far left content as hateful. Usually it expresses an intolerance for intolerance or hypocritical actions.

Is there even a point to you speaking here? You're like an incel on a women's forum. You've transitioned into a complete non-sequitur.
> You don't get why a online forum might have an interest in ensuring every other post isn't a dick pic?

The confusing part is not that they're attempting to clean the site - it's their ineffective, half-assed ways of doing it.
Ask HN: Open-Source Alternatives to Restream?
Trying to figure out how I might run a self-hosted solution that accomplishes the main feature of Restream, that is, multiplexing a single RTMP stream to various platforms at the same time. (Youtube, Facebook, Twitch, etc.)

I get the sense that Nginx could be configured to do what I want to do, but does anyone know of an open-source solution that comes ready to do it out of the box?
No default apps, which is the biggest reason I use Android.
You may be (un)pleasantly surprised by the amount of physical/real-world tracking of in-store traffic that stores are engaging in now. In many physical stores, you don't really have the option of "'browsing' without them already tracking me" either. Worse yet, there's not even a pretense of viewing/accept some Terms and Conditions when you physically enter the store (at least websites pay the lip service of having a T&C posted or a cookie consent pop-up).

VC News is basically a Reddit clone to show off pg's then-up-and-coming toy language.

• Discourages long-running discussions by burying (and ultimately locking) older content

• Discourages coversation in favour of fire-and-forget comments by making it impractical to continue where you left off

• Gamification of content

• Numerically larger groups can bury content they would prefer others not see

— but slightly worse —

• No notification of replies, making actual discussion impractical

• Extra privileges for conformity (downvoting, vouching)

It doesn't match what pg wrote in http://www.paulgraham.com/say.html but actions speak louder than words.

I think if I were female, I'd be a more successful founder. As a white male, I found that no investors were even willing to talk to me in spite of being an early employee at some great startups including Airbnb. I applied (and interviewed) at YC multiple times and was rejected for mostly BS reasons, which I think were just a cover for "we don't like you". I get it, I'm not a likable person, it's something I have to live with every day and I hate it about myself (also I'm mildly autistic, which doesn't help).

I've given up on the startup thing because I lack the necessary connections to get ahead. Without funding, I can't market properly, and I can't hire sales people. It doesn't matter how great the product is, because at the end of the day it's all about sales and marketing.

There's a significant number of VCs and funds which only invest in female founders, which is a huge advantage. The bar is much lower, which is great if you're a woman. It's just like hiring programmers: 2 sets of standards, one for men and one for women. For better or worse, that's the way it is.
First, big brands don't want controversy displayed next to their ads. This is likely behind some moves Reddit has made in the past to clean things up.

Second, I'm curious what % of revenue comes from user-purchased post and comment awards from gold. I've noticed those in use quite a bit in some more inflammatory subs like /r/politics. I wonder how they vet payments from users to avoid providing a way for hostile actors to buy visibility while flying under the radar. Ie. Avoiding conflicts of interest from accidentally monetizing trolls.
First, citizens possibly being more armed than everyday police is not a bad thing. Parking enforcement and process servers are less armed than the people they confront. It generally takes two to escalate - if a moving violation turns out to be a cornered violent felon, you want them to drive off rather than expecting a single officer to control them in the heat of the moment!

Second, firearms could still be carried in every vehicle in case they're needed. For example, the National Park Police does this with rifles - ready to go in case needed in a remote area. This idea that a police officer responding to routine incidents may suddenly need to draw their handgun and start shooting is exactly the problem.
> They have set literally no trend in the last couple of decades, other than thinness at all costs

Hahaha then you have not kept attention. Apple led the trend away from beige boxes. Style of keyboard used. Large track pads. USB. First to remove floppy drive. Both hardware, software and web design has been heavily inspired by Apple. Just look at icons used, first popularized by Apple.

Ubuntu desktop is strongly inspired by macOS. Operating system with drivers preloaded through update mechanism was pioneered by Apple. Windows finally seem to be doing this.
Welcome to IEEE Bushy Tree
I was riveted by Half-Life in 1998, but I recently picked up it's well regarded remake Black Mesa (which updates the graphics to approximately 2006 levels) and IMO, it doesn't hold up at all.

Nothing about it is epic - it feels like a cramped dungeon crawl. The gameplay and puzzles are extremely simplistic (lots of slow moving enemies crawling down a hallway). The story is a bad B-movie compared to some of the compelling modern games that are raising world-building to new levels. When you compare it to modern games, I don't see how anyone could justify spending more than an hour or two on nostalgia playing.

This seems to be an area full of quandries.

If data is your property, then you can sell it to someone else permanently without royalty. Expect to see signup forms that say your first month of SaaS app is $0.01 and you will receive a credit for $0.01 for selling your data to them.

If data is Intellectual Property subject to royalty like other intellectual property (say, stock photos for example) then you can assign away the royalties and we can expect it to be assigned away in the signup form or EULA.

If data is a form of labor it will be subject to minimum wage laws and other employment law.

If data is intrinsic to the individual it cannot be sold or reassigned (like i cannot sell or reassign my other human rights).
