Honest question. Can someone explain why the comment below was flagged? I can see why some might disagree but I fail to see any problematic about any of the statements made. I think of HN as one of the few places were people can have open discussions where everyone is free to state their opinion and have it up for debate/rebuttal.

"I disagree. Reports about China from many western media tend to exaggerate things about China, mostly influenced by western politics, not good at all. Also, western media tend to report selective facts to only show things they want people to hear and see.
The right to life is the first clause of human right, which I see they are violated in many western countries. They refuse to treat the poor and old. Do you hear China criticise? Maybe they are, but for sure western media choose not to report them.

Freedom of speech is a relative term in today’s world. I can say some of the things you shouldn’t say in China are equally not welcomed in many western countries. If you split US, see how many troubles could come to you?

On democracy, I’m not sure what to comment. China has ran 4000 years under one empire system, and it’s just the culture there. Why democratic society is better than the 1 party system? What’s more important is to have the party represent people’s interests. In many democratic countries, each party represents the interests from certain groups, that’s why it’s necessity to have multiple parties perhaps. The downsides to democratic system is also quite obvious. There are countless debate on many small matters which waste tax payer’s money etc.. Also, the democracy can be manipulated, and if it is the case, it’s worse."
But the question whether they really produce less pollution over their whole life time is still not settled. Production of the battery pack is quite energy intensive, lithium and neodym mining is not without problems. And you have to move around the battery pack all the time.

If electrical energy storage were the most economic one, I would expect at least one species to do that. Instead, they all store their energy in chemical storage mechanisms, i.e. fat, glycogen, ATP/ADP etc.

In order to solve the climate problems, it would be enough to synthesize gasoline from C02 in the athmosphere using renewable energy sources. A break through here, could immediately revert the whole trend towards electric vehicles. Of course this would not completely solve the pollution problem. Just CO2 pollution.

>It's all scripted. Google books and archive.org have been great resources.

Do you use any off-browser tools to navigate archive.org / google books? if so which? or the web sites always sufficed?

>There's also a couple torrents of 17th-19th c. journal articles.

Could you expand a bit on this? This sounds very interesting for a project of mine! Where did you find torrents of 17th-19th c. journal articles? It sounds like the copyrights on these would have expired, did you find human curated database of this era journal articles? how comprehensive is it, all journals of this time span?

(one of the things I would like to do is map out the transition from alchemy to chemistry, for example WP states Lavoisier convinced the scientific community that sulphur was an element and not a compound, which sounds utterly bizarre for essentially all of us who were exposed to chemistry as a deductive system without the abductive reasoning that led to it)

>I've made my own sqlite databases from the meta information and ran ocr over them to make things searchable.

That is pretty amazing work!

> I'll be putting more of these tools in the repo and eventually put the search systems online for the general public. Google's navigation of annualised volumes is a joke so I'm going to do better.

Where is this repo you mention?

No, you cant.
That'd probably work fine too, but anywhere where I care about appearance I need to cut the electrical tape while the dot stickers are available in just the right size for fractions of a penny per sticker, so I have what appears to be a lifetime supply of stickers anyway.
I always hear the argument that college/grad school is silly because you can go read the textbooks yourself.

It requires an immense amount of motivation to grind away reading 80 pages of a boring CS textbook every day. The structure and motivation provided by an institution encourages people to go deeper, meet deadlines, and not just skim the boring stuff. It isn't the only way to learn, but when I did a master's degree I felt motivated even when the road was rough.
> Europe does not have to align with either side.

Let's hope Europe makes the moral choice here though and aligns against China.
Agreed. Pagerduty and similar notifications systems can be life savers for support people. Especially if they are integrated into a ticketing or event management system.

The entire county smelling the burning ship for the 3rd day today, and they estimate a week total, seems more of an embarrassment to me. The military blows through 1.5B and the public wouldn't bat an eye. Leaving a flaming ship less than a mile from a major downtown for a week, and everyone will (is) complaining at the wastefulness of the Navy. I live 6 miles away and going outside is unbearable, people are smelling it 20+ miles away in Alpine and North County. I have been trying to imagine what it is like in the neighborhoods adjacent to the base right now, it was a hot week, and many don't have AC, keeping the windows closed is a nightmare.
Each marginal ton of CO2 is going to make things worse. It's not like there's a threshold over which things are going to be maximally bad. It could still be worse if we pollute more.

It might be difficult to measure a single such cut, but a few hundred could be noticeable. https://arstechnica.com/science/2020/07/manage-your-expectat...
SEV: No changes are required to the apps, better performance, but bigger TCB. GCP mitigate this with Shielded VMs, in particular integrity of the kernel in your trusted boundary, notifications to users if the integrity state changed from the baseline and made it default and free. https://cloud.google.com/blog/products/identity-security/sec...
SGX: smaller TCB, but limited scale, and you have to partition your app to secure and no-secure parts using one of the SDK available, Intel SGX SDK, Microsoft OpenEnclave or Google Asylo.

I assume you mean "they're not friends", rather than "they're all just friends"?

That doesn't really echo my experience, I have many good friends from past jobs that I'm still in contact with. Though I've also definitely gotten frustrated with people we seemed to get along with at work but then didn't ever seem to want to hang out outside work...
Right, and and xhyve, Hypervisor.framework, and kvm are all frameworks for creating and running virtual machines. In contrast, Docker for linux runs using a native container mechanism without using a VM at all. macOS doesn't support containers, but it could.
4 years at peak human population means a lot of human-years have transpired. And we've only been doing this oil burning industry thing for a few hundred. I think 4 years is quite a long time because of the scale of human progress.
How to grow newsletter subscribers without base of Twitter followers?
I recently started EastVC.News - weekly newsletter about startup funding in Boston and NYC. First 150 subscribers were relatively easy (friends, LinkedIn, FB groups) but now I'm stuck. Getting max 1-2 subscribers per day. Twitter seems like the best place to promote it but it is super hard to get followers and nobody is answering if you send them messages. Is there any other hack that you did to get more subscribers?
This doesn't work for me

I am not a fan of such comments, they always want either a perfect solution or no solution at all.

There was this guy who debated with me online about using solar panels because 'they are not efficient enough' and another one who debated planting trees.

It is a step by step process. We will not magically cure up the ecology in one day in one swoosh. It'll take small efforts from various aspects.
Yes. Apple is a religion and faith needs to be regularly be tested in order to grow stronger.
> to price carbon emissions

"A carbon tax offers the most cost-effective lever to reduce carbon emissions" is what 27 Nobel laureate economists and about 4000 other economists said in a statement in January 2019 [1]. There are some opposing opinions on some details [2]. Anyway, to an outsider this appears to be the scientific consensus.

Do you mean those resources physically located with you? That's a good assumption.

Or do you mean those resources physically located in someone else's data center running on their hardware and software platforms among their infrastructure and only assigned to your task as-needed? That's a bad assumption.
Couldn’t agree more.

If the website is breached, the login isn’t a login for any other website, and advertisers have a harder time correlating your identity, and if you get spam you know who is the culprit, and you can stop the spam by deleting the alias.

With this, no need for any other antispam logic. Back to the mid 90s (which is a good thing as far as email traffic is concerned!).
Ask HN: How would you improve online education?
My daughter did zoom classes for the last part of the year. It was less than ideal. She also used an several online resources. Nothing really seemed amazing for online education for kids.

How would you improve the online aspect of education for kids?

What big idea would change everything?
Like the BBC or Australia’s ABC?
This exists
> But for at least Portugal and Greece, and maybe Italy and some eastern European countries, the ally is china since 2014?

Maybe financially, but not ideologically. Not sure how far this "allegiance will hold".
I only saw that in "A Comparison Study of Intel SGX and AMD Memory Encryption", which per my grandparent comment, is not a trustworthy source (they reference the whitepaper, and the whitepaper doesn't say anything about it).

Is that documented in an actual AMD source, or even talk?
Retired Navy here...

Yes, it will probably be cheaper to build a new one at this point.

Yes, steel is compromised, wiring and electronics gutted. Millions in equipment that isn't even made anymore has been destroyed. Many of the systems in the island are moved from ship to ship as new ships commission as they can't make new ones anymore. This is the worst fire disaster the Navy has had since Forrestal, with the possible exception of the Miami. We're just very fortunate nobody died.

Yes, nearly all fuel is normally removed -- both DFM and JP5, all of the USMC equipment would have been removed, all of the ammunition and arms (remember, this is a mini-aircraft carrier, it absolutely does have a fuckton of ordnance onboard in normal operations) would have been removed. In this case, and I have no idea why, they had 900k gallons of DFM onboard, which is not normal for a maintenance period and suggests perhaps they were doing tank validations or something.

There is some truth to this. For in-person lectures I could just show up to class with a general theme and blather onto the whiteboard, whereas online, all the students want text lecture notes, slides from the lecture, they don't ask questions during lecture, so they are confused, taking time later.

If you spend time editing together a pre-recorded video, it can easily triple the amount of work. Even if you go with the pro-style one take, you need to rehearse and have a good plan in place to make such a video.

What I got after messing with it a bit:

The "cover costs" assumes your people will use the tool 8 hours a day. By the productivity you gain, it calculates how much you save in salary.

The "free up an hour" also assumes your people will use the tools 8 hours a day.

The "cover costs with" calculates how much your people must use the tool for it to eventually pay for itself. If it's larger than 8 hours, then the tool will never pay up.

Data in cloud and probably on the device you're using right now is mainly only encrypted while sitting on the disk and when bouncing around the net. The difference here is that the data is also encrypted throughout its life - while in memory and while the data is getting processed on the machine.
Gave me ideas . Man I thought I was the only one that made a huge mess with electrical stuff on the desk . I was trying to emulate my lab setup from school this whole time and what I really need is just the foldout desk from the attic.
Technology Dependency is About More than Mental health
I think it's mostly because the eye is drawn to motion/change, which hijacks your attention. When the turning light is blinking on-off, it only distracts you for a fraction of a second each time it blinks, while alerting you to the driver's intention.

The animated turning lights are in motion closer to 90% of the time, so it takes a second to tell you what blinking light tells you in 10 milliseconds, and uses far too much of your attention bandwidth compared to how much information it conveys.

I think they should be illegal. The light should alert you and let you focus attention elsewhere, not mesmerize you with useless fanciness.
My understanding is that the difference between 5G density/localization and that of previous technologies is quite substantial, especially in urban areas.

"The extension of spectrum range has an impact on the network architecture. mmwave cells will employ shorter ranges of around 100-to-200 meters which will require extreme densification to provide high coverage. 3G networks reached densities of fourto- five base stations per km², 4G networks eight-to-ten per km², while 5G networks could reach densities of 40-to-50 per km²."

> Low fuel is more dangerous than high fuel. Most Navy fuels will put out low temperature fires on contact - the ignition hazard is from the fumes. A mostly empty fuel tank full of vapors is easier to catch fire and more explosive when it does.

-- that's for mogas and such, dfm doesn't really have that problem. Most tanks are kept empty in yard periods.
Yeah, absolutely. It's like people forget that teachers give assignments, answer questions, grade homeworks, run exams, and you know, do an actual job.
Search for "black dot" on Amazon. You can find stickers in various sizes that are good for dimming LEDs. Unless it's a really awkward shape you should be able to find one that'll cover the LED while keeping the button usable.
It is possible to have those networks talk to each other using bi-directional 1:1 NAT, but it will almost certainly cause you far more trouble than it is worth. I have done it, and I don't recommend it.
Sometimes USA still manages to do the right thing it seems.
I used to get sleep paralysis in my teens; it was extremely scary the first few times but when I understood what it was it just became annoying. My mind would wake up almost immediately but it did take significant mental effort to regain feelings.

In my early twenties I experimented with lucid dreaming for a bit; since then I never had sleep paralysis episodes but I do not know if it is connected; it is entirely possible that getting older awareness is just suppressed more while sleeping (apparently you dream less as you get older).
Anecdotally I've always perceived that dress as blue/brown from the very beginning and I can't "switch" my vision to perceive it otherwise. It's incomprehensible to me that someone can see it as blue/white or even worse as black/gold :)

An interesting but contested claim by an anonymous intelligence source, that CIA (or an asset) used African Swine Fever as a bio-weapon in Cuba two years after the Nixon administration publicly ended US bio-weapons programs, and a few years before the international bio-weapons convention. Apparently Chomsky promoted this claim as well. This seems perhaps no so far fetched considering other US intelligence shenanigans that were evidenced to have occurred at the time in that region, but this particular event doesn't seem to be publicly evidenced.

I went as far as attempting to confirm that at least the _claim_ itself is broadly recognized, and the article was really published by SF Chronicle, because... well, in 2020, what is even real? :p
Because other things achieve something. Me getting a new job won't save the world, but it will improve my income. This achieves nothing at all, for me or for the environment.

We have a huge problem at the moment where people think they're achieving something by personally cutting their co2 emissions by a few kg per year. Global emissions continue to rise. So they're not achieving anything.

Before we can achieve something, we have to get people to realise they are not already solving the issue.
Sounds like your company needs to do a little more evaluation and due diligence before buy an off the shelf product. I work at “Megacorp” and it took way less than 2 years to get 20k employees and an equal number of customers onto our off the shelf ticketing platform.
Which studies are you referring to that argue for the abolition of public education? Again, clearly homeschooling can work. Equally clearly it can't work for everyone.

FWIW: how were literacy rates during those thousands of years where peasants were responsible for schooling their own kids? And symmetrically: which culture was it where the members of the literate aristocracy schooled their own children instead of using tutors/monasteries/etc...? That argument is just silly on its face.
Grant's intelligence and creativity was always inspiring. This is very sad to hear.
What is the attack Vector that this solution prevent ?

Am I missing something obvious ?

Will it prevent Google from being able to have a Root access to the VM?

From my understanding it does not seem to protect from Google. If they are still able to have a Root Access to the VM it does not matter if the memory is encrypted or not.

The only thing that I see, is in case of a spectre/meltdown vulnerabilty where the isolation of the RAM fails...
Sounds like a corona-induced aneurysm.
I see this alot too. Products that are forced from above and not used, used under gun point etc. Also products that kinda don't fit in and where it would be just better to build it in house since the subset of functionaliy that is needed is quite small, and so on.
We are still in the "yes and" times
I agree. But there are other corner cases where that would be helpful. I’ve worked at a lot of software as a service companies where your email address has to be unique per client for a multi tenant system.

We would create different users for different roles. I would love to be able to use one email address distinguished with a tag.
Now imagine after you posted your comment some men bust down your door take you in, torture you. Not some sleep depravation, but hammer to your knees and electrodes to your testicles. See difference? Oh and yeah nobody will ever see you again, cause well you are just gone.

Thanks for this, looking forward to it!
But it is whataboutery.

We're discussing why the UK might not want a Chinese state-allied (if not owned) actor embedded in its comms networks, and here everyone is saying "buh buh buh America!"

And frankly if you look at what's happening with BLM (mass protest in the US over a pattern of racist police murders, significant parts of the country vocally criticising the apparatus of state) and consider that somehow worse than the semi-secret genocide of millions, with all discussion suppressed, going on in China....
I remember being disappointed with their testing and results at the time but it was 14 years ago maybe I didn't get it right.

I don't think they are overly rigorous with in general but its still a great show and I actually dont think they tried to portray themselves as strictly following the scientific method either.
Expert Republic just launched their app in Product Hunt
So far, we're making less than no progress because global net co2 emissions continue to rise. Do you agree?
That is exactly what BT have been saying. Moreover they rightly point out that losing access to software updates due to US sanctions is a security risk in its own right too.
> I was refuting the claim that formal schooling is necessary to get an education.

Which was a claim that no one made.
Why i am not even amazed about that?
The cost of that victory, according to the BBC, is a 1 year delay in the rollout of 5G tech.

That's a pretty large economic cost. Bob can't watch his medical lectures on the train, so ends up behind in class, Mary's company looses a contract to a foreign competitor because she got frustrated with her bad VPN and didn't read over the bid one last time, Fred couldn't afford the cost of the new 5G contracts so didn't get much data and ended up losing touch with his friends who were all group video calling eachother.

All these socio-economic costs cascade for decades or more. Do they really outweigh the theoretical ability for another nation to disrupt network traffic for a few hours until a mitigation is put in place?
I think this is true, but I don't think most people are aware of this. As the world becomes swamped with fake news and content of all forms, more people will realize that humans are not the rational beings they think they were. Perhaps that will result in more services that optimize for emotional well-being, i.e. the opposite of the Instagram and Facebook's.
It really does suck you have to pay upwards of thousands of dollars just to get some brand name on your education credentials. And thereby having those credentials do opportunities open up. Have you ever seen Suits? The premise of the show was about a young man who gets into a top law firm in New York by lying that he went to Harvard Law School.
May as well note: SEV relies on AMD-signed vendor firmware blobs. This means that AMD, or anyone who can get their keys, can compromise the security of SEV.

> So liberals or centrists who fear the left-wing zeal for cancellation need a counterargument that doesn’t rest on right-to-be-wrong principles alone.

The only solution to cancel-culture is to fight entitlement and promote scientific thinking. The main danger of current decade cancel-mobs lies in how they vew all "problematic" thoughts as a pure evil that taints all reasoning derived from it or that lead to it.
Disclaimer: this is just my view as a Canadian, not sure if studies back this up.

I think it's a feature. We seem to move a lot faster and it doesn't always work, but for the most part, having MPs as the executive branch allows people at the top to legislate what they need to succeed.
