This is where they started.

The story I was told was that president Lyndon Johnson was having heart trouble. Coming right out of the Apollo age, the powers that be said "we can send a person to the moon, why can't we build an artificial heart". They thought it would be a relatively simple problem to solve. At that time the battery technology wasn't there, so the only way to make something work was nuclear power. They came up with an implanted sterling engine, powered by a nuclear thermopile with the cold side of the heat flow being the human body. In that case, the limiting factor for how much power could be generated was how much heat could we dump into the human body without causing things like internal burns and necrosis. They actually built several prototypes, tested them in animals, but never in humans. These devices were enormous, they typically had a large thermopile/sterling engine portion connected by a shaft or hydraulic connection to the pumping portion of the device. Both needed to be implanted in the body, and the devices were entirely mechanical, no electronics needed. The thermopile drove the sterling cycle engine, which then either acted on hydraulic working fluid to actuate the blood pump, or used a shaft or similar to actuate the blood pump from the sterling engine.

The problem was and is not in communism per se. It's the Cuban leadership policies that produced a lot of protests in the U.S., repeatedly. See the timeline.

It’s possible they saw firing their head of diversity (which I think they should have) as politically messy. Easier to fire some people of color than others. In the situation you pointed out, Google may have feared BLM more than they fear the Arab world. It really feels like there’s an algorithm at work here, not rational sense.
I wonder if everyone is therefore incentivized to not send out such probes, then. Since no one can guarantee they are advanced enough that their probe won’t get captured by someone more advanced who just sends back a scarier probe as a thank you gift.
So what's your stance? We shouldn't allow individuals to operate ham radios or provide to their own self defense because it doesn't matter anyway?

Every organism has the right for self defense and communication, whether you or a government agrees with it.
Especially as the news about the election fraud slowly rolls out across multiple states...
I'm not sure I understood your point correctly. I interpreted what you said as meaning that Starship being 10x better than the Shuttle would be a significant improvement.

I'm saying that the Falcon Heavy has already achieved a 35x improvement from the Space Shuttle, and therefore if Starship achieved only a 10x improvement relative to the Shuttle it would actually be worse than what we already have and so wouldn't be an advancement.

If you meant 10x relative to current rockets, then yes, I agree that would be significant.
Ask HN: Technical Post Where Pictures Didn't Scroll
I remember seeing a technical blog post in the last few weeks where the diagrams stayed in place while text scrolled, and thought that was really useful for teaching. But I wasn't able to find it through search. Does anyone have a link to that post?
It is a metaphysical statement about whether metaphysics is important in this instant, rather than being dispensed with in favor of something useful. It's picking a particular metaphysics rather than being bogged down in the meta-metaphysical question of the necessity of metaphysics.

Or at least, that's the way I read it. The question of the value of metaphysics is an open one, which easily comes to dominate other questions if allowed to. I think the OP is saying, "I'm going to make a metaphysical commitment, and let other people worry about whether doing so is good metaphysics." (And there's good reason to think that it isn't -- but it's unclear whether that matters, or should matter.)

I disagree on this, because biofuels are a viable substitute in almost every situation.

I'm fairly certain that our accumulated knowledge would make a second industrial happen even faster in spite of fossil-fuel-lack (but it might play out slightly differently, because of higher fuel costs...)
That’s exactly why images tend to be compressed in a YUV colour space instead of an RGB one.
> New variant, people panic and demand action

Why would they panic and demand action?

TFA says vaccinated people mostly don't get infected by new variants, and who do are asymptomatic or have mild symptoms.

> I sure hope drug makers don’t suddenly decide that vaccines are profitable, I would hate to start seeing commercials on television for the vaccine of the week.

So what if they decide whatever they want and advertise? Don't watch commercials. They can't force you to do do anything.

It's amazing how HN readers tend to worry about the wrong things (such as capitalism and Covid, for example). The things you should worry about are governments and international organizations, but that's precisely what you aren't worried about.

Who's more likely to make you take a new vaccine every year, Joe Biden or the CEO of a vaccine maker?
Then use "prostrate", or "abject submission" when means the same thing, more or less. English already has words for this!

It is not about accuracy, but about language that is stereotypically reserved for when talking about China, and to my ears, it comes off as a bit racist, tbh.
The parent spoke about ham radio legislation and gun control legislation as being anti-revolution legislation. The person I responded to said the parent lost him at gun control. Since he/she didn't seem to get the connection, I replied that this is because they haven't read the Constitution, Bill of Rights, and Federalist Papers. After all, the entire point of the 2nd Amendment is so that US Citizens can overthrow the government; so, obviously, any legislation against the 2nd Amendment would be, by definition, anti-revolution legislation.

Exactly, the human heart is a marvel of design and performance.

Typically these devices use between 10-30 watts of power for each side of the heart (in the LVAD case). For an artificial heart (which is two LVADs, basically a LVAD and a RVAD) it's more like 30-60 watts of continuous power.

The human heart is amazing.

> is choked by bureaucratic inefficiency, fuel shortages, disincentives for farmers and so on...The embargo has nothing to do with that.

Bureaucratic inefficiency and disincentives for farmers aside, the fuel shortage seems directly tied to the embargo:

HAVANA (Reuters) - Cuba must implement emergency measures to stave off an acute fuel shortage in September caused by the Trump administration’s efforts to block oil shipments to the country, President Miguel Diaz-Canel said on Wednesday.

It varies by patient, but the average monthly costs I've seen seem to gravitate to either 3 vials/month or 10 pens/month. There's 300 units in a pen, 1000 in a vial, so the averages are based on 3000 units/month.
Hostile? I don't know what you mean.
Putting the megacorps that have manipulating people on behalf of others as their primary business model in charge of determining truth. Cyberpunk dystopia, here we come (except for the cool gadgets).
Last I read there were a few folks with them still implanted to this day.

It's interesting, one of the major development challenges for these devices was making them safe so that if the patient were to be cremated they didn't create a small dirty bomb.
It sounds like you need to be discrete / careful in public, which makes sense if it's illegal. In California, it's legal, but in city areas it's usually not allowed outside or inside, and when you rent, most places will say no smoking of any kind inside. The only way I can think of where I could smoke "in peace" would be to buy a house and smoke inside or a patio, if far enough from the dense cities.
(3x400k = 1.2kM). There's a lot of competition around 1.2-1.6.

I'm missing the point here, which is that it is extremely expensive and only the highest income earners can think about a single family. We obviously need to build a shit ton more condos. No wonder people are homeless. No shit.
It seems to me like there's two main kinds of lies that interrogators use:

1. Lies about the process / promissary lies. e.g. "If you just confess, you can go home."
2. Lies about evidence. e.g. "We talked to {Friend|Family|Co-conspirator} and they said you did it and they have the {item} to prove it. It's not going to look good if you continue to lie to me."

#1 seems obviously bad to me. Too high of a risk of tricking innocent people into thinking they can end the stress by falsely confessing.

#2 seems less bad, possibly beneficial. There are other comments about how this can speed up interrogations by getting people who are guilty to think they've been caught and confess. I could be convinced otherwise.

In my opinion, sounds like 1 and 2 should be illegal for minors. But 1 should be illegal in general, for adults too.

I use a combination of pen and paper, and sticky notes on a wall mounted detective board for things to do immediately.

I also use Simplenote. Free with markdown support, sync, and publishable links.

I use Samsung Notes for trivial stuff, like chores or shopping list.

If I want to easily sketch inside a note app, OneNote is the best. But it is weird in a sense that there are two OneNotes- one that comes with Office, and anotherthatcomes with Win 10. But OneNote is buggy and slow. You can barely use it in mobiles. I don't use windows that much.

Which brings me towards Obsidian. Best data policy, custom plugins, and what not!?

I am using it everyday. I am using another sync service to sync between devices.

My vote would to to-

Obsidian + Simplenote.

Lessons from a year building machine learning tools
I feel like that's the same thing as arguing that your taxes shouldn't go towards public schooling since any one of those parents could have chosen not to have a child.

If that argument strikes you as problematic, it might be because society is better when it's generally well educated and healthy.
It was a good rant
When comparing value with the switch, factor in:

1) Nintendo switch game prices

2) The size of your existing PC-compatible library (including emulators).

That drastically changes the value proposition to me.

There are people with Heartmate II's (LVADS not artificial hearts, so a bit different) that have lived 10+ years on the devices, with a very high quality of life. That's worth it in my view.

> Now is that true?

No. The root cause of the embargo is, manifestly, that the Cuban Revolution ousted American capital interests from the island and gave the preverbal finger to US economic hegemony. All else is secondary, after-the-fact justification. Broadly similar story for Iran. The US has proven time and again that it ultimately has little interest in things like democracy and freedom, but if you fuck with the money, woe be to you.
That ship sailed along. In the interest of putting the police force ahead of the community it is supposed to protect the police have burned lots of goodwill. Even now being called police is considered an insult amongst the youth. It used to be snitch, narc, or opp. Now you’re called “12” when you’re not to be trusted.
I think this could be a very effective countermeasure. It reduces trust between members of a crew, and between crews themselves. If you're constantly suspicious of Ivan the mail campaign guy ratting you out for a payday, it makes the whole business focus more on opsec and less on offense. Though sole operators can do plenty of damage on their own, they probably are less likely to be state-backed.
I was 9 years old when Hubble was launched, today I am 40 years old, so it has been around for all of my adult life and then some.

Also, it has provided lots and lots and lots of beautiful pictures that are stunning to look at even for people who otherwise do not care about astronomy at all. I think it's fair to say that no other project/mission/device since the Moon landing had a bigger impact in making astronomy "cool". The Hubble Deep Field pictures alone are breath-taking, and they may very well have had as much of an impact on our current model of the universe as Hubble's original discovery of an expanding universe, at least from the perspective of a non-scientist.

As far as I can recall, Hubble was supposed to go down in flames quite a few years ago, but it just kept working, and no equivalent replacement was available. James Webb Space Telescope is not exactly a replacement, as it is an infrared telescope. It will be quite interesting to see how long they can keep Hubble working. It had a rough start, but the fact that after some initial corrections, it has lasted way longer than it was supposed to speaks of the quality of engineering that created it.

The voodoo doll seems like a weird example to use, these people weren't sitting in their houses imagining it. They literally broke into congress in search of congresspeople, you can watch videos and hear people say "where are they"... they went to their offices and congressional chambers to find them...

Analogies aside, if you don't think it was an attempted coup... what would it have made it one? I'm legitimately curious (I don't think incompetence is an excuse, and courts usually don't either).

Thanks for pointing out the disparity about Sicknick. To anyone else who isn't aware... the autopsy determined he died from a stroke the day after. These people still assaulted police officers to gain access to the Capitol.
So excited to skip rebase/merge hell! Congrats on the launch!

That's not what you assume as an individual because it's your job. Day to day you do the right thing.

I dropped out of gymnasium and spent 2 years doing nothing and enjoying life with 14 or 15. Mostly smoking weed and taking other drugs. I am sure most people from then believe I live on the street by now.

Some years later I finished school, got a diploma, worked a few years and now I am self employed and have more free time than anyone else I know. I love the job I created for myself and I contribute this in parts to being a little rebel. Pretty sure my IQ has not dropped yet either

All while still taking drugs.

IMO the factors you mention are environmental and not directly related to drug use.
>Plenty of businesses are based on patented secret sauces.

Secret sauces are, by definition, unpatented - if a business has patented an idea, it is no longer secret, and the success of that company is then partially enforced by the exclusivity of the patent. You don't need a non-compete if your employees have access to patented content, because they aren't legally allowed to reproduce it anyways.

>Even for the type of companies that rely on execution, there will be important lessons learned, which ultimately become the "secret sauces"

Can you give an example of this? I think it's unlikely that specific "lessons learned" could be so valuable. Sure, companies are afraid of losing their experienced employees - but all companies are afraid of that anyways. It has little to do with the idea of a "secret sauce", and everything to do with simple experience.
I think not competing with any area in which the company works is a convenient test. But I suspect the ultimate legal test is actually more constrained. One more like: do not compete with an area for which you directly work in or are exposed to information about for the company.

To respond to what you feel is your point: 911 operators are not police officers in my state (NJ). They take and log calls and information, and may hand it over to the police, but they are not responsible for investigating crimes.

I can call 911, report a crime is being committed with the intention of having the police intervene, provide no additional details beyond that, and then never speak to a police officer unless they subpoena testimony from me (and even then, issue statements through a lawyer).

This is why I'm defending the video. We live in a society, and I fully accept that while also accepting that I don't trust cops ever under any circumstances period.
I think anything communications related is spy games all the way down.
If a job is paying less than what the government deems the minimum amount of money you need per month to survive, then it's an obvious choice. It's also obvious what employers need to do if they are short-staffed.
Note that -- and please correct me if I'm wrong -- Canada has a weird system where the suspect isn't allowed to leave the interrogation (but surely there's a time limit?). I've seen videos where the suspect just sits silently while an interrogator mentally exhausts them by asking the same question over and over. I believe in America the suspect would either just leave the room or, if already in jail, go back to their cell.
This is a good thing. It means employees have an option to chose work that’s good for them, and can reject jobs that would demand unbearable sacrifice with little reward. It allows folks who would otherwise never get a chance to breathe to learn new skills and compete for better work. I don’t want to live in a society where 2 million jobs are taken only on threat of starvation.

Surely your accounting class tell you that rising revenue doesn't necessarily mean that "margins just keep climbing"

I've been interested in audio. I have no electronics background, so I am overwhelmed by the topic. I find there's a lot I don't understand, and a lot of tutorials online don't quite give me an understanding I'm looking for.

If anyone is looking to be inspired (rather than be informed, necessarily), check out the crazy English guy (is there any other sort?) who runs the channel Look Mum No Computer:
https://www.youtube.com/channel/UCafxR2HWJRmMfSdyZXvZMTw

He's got quirky things like a Furby Organ, a 1000 oscillator megadrone, and a cryptocurrency synthesiser. He is also opening a museum soon: The Museum Of Everything Else, dedicated to old music and electronic stuff. It even includes a telephone exchange and his Googol clock, which he plans to never turn off. He also has a flamethrower synth, which he uses indoors. And he has a safety pin for an earring.

Love it.
Google should put a big question mark on the dotted line.
Seems reasonable until you're the target. I personally think companies each enforcing their moral compass w/r to whom their customers can be creates too much of an unstable landscape (particularly societal).

This is one of the reason we have more and more protected classes. Political ideology just isn't one (yet?)

I suspect that actual number is probably even higher. If I were on extended unemployment benefits I would be very hesitant to answer this poll truthfully for fear of getting cut off. Could it be an audit masquerading as an independent pollster? Better safe than sorry.
It appears as though this post has been memory-holed.
So the right to life is a human construct? That means that it is totally okay for the police to shoot everyone they don't like.

Rights are not a human construct; they are inalienable, given by a Creator, and we will be accountable to Him for stepping on the rights of others, and He expects us to do what we can to preserve the rights of others as well.
From what I've seen in the USA they normally lie about evidence and witnesses but they are careful to never lie explicitly about making a deal. That can apparently screw up the entire case, I think because of a supreme court decision.
Yeah honestly it's a bit wild to me that this is a controversial take, and the proposals to "solve" this problem have largely been to cut people off from benefits.
I worry that this framing tends to exempt the authorities from responsibility. The article talks a lot about the raw effect of the flooding, a lot about high-level climate goals, and barely at all about how governments should tackle the problems they're facing today. It does quote a professor who says the tragedy "should have been avoided" because "the warnings were not taken seriously enough and preparations were inadequate", but shouldn't the biggest question here be how they were inadequate and which additional preparations ought to have happened? Surely there's gotta be action items beyond just renewing our commitment to reducing emissions.
I'm surprised to see that rejecting non-remote job offers is the reason for 11% of the respondents rather than a smaller portion. I guess that's another positive indicator that the shift to long term remote work is going strong.
It also shows that we have paved over too much soil. Cities hardly have any ability to soak up extra water. Whenever I walk outside in a stronger rain and I see the torrents of water gushing over the hard surfaces directly to the closest gutter, I can't help but think that our ancestors would judge us pretty harshly for treating rainwater like nuisance and not a resource to manage wisely.

It wouldn't have helped in this case, though. No clever water retention system can cope with such a downpour. Maaaaybe it could mitigate the worst results.
