"Abstract:

O3-layered metal oxides are promising cathode materials for high-energy Na-ion batteries (SIBs); however, they suffer from fast capacity fade.

Here, we develop a high-performance O3-NaNi0.68Mn0.22Co0.10O2 cathode for SIBs toward practical applications by suppressing the formation of a rock salt layer at the cathode surface with an advanced electrolyte.

The cathode can deliver a high specific capacity of ∼196 mAh g–1 and demonstrates >80% capacity retention over 1000 cycles. NaNi0.68Mn0.22Co0.10O2–hard carbon full-cells with practical loading (>2.5 mAh cm–2) and lean electrolyte (∼40 μL) demonstrate ∼82% capacity retention after 450 cycles.

A 60 mAh single-layer pouch cell has also been fabricated and demonstrated stable performance. This work represents a significant leap in SIB development and brings new insights to the development of advanced layered metal oxide cathodes for alkaline-ion batteries."

The irony is that Hacker News is literally unsafe to use as it puts users at risk of doxxing by not providing basic privacy functions like post and/or account deletion or even the ability to change your username. I really don’t understand why the HN crowd (which claims to be privacy focused) never seems to call this site out on that. Did I miss the text when you sign up telling you that everything you post will be publicly accessible for the rest of time? Is there even a mention of it anywhere?

To answer the original question though, no Facebook isn’t safe and never was. Delete your account. I did four years ago and I’ve never missed it.

> It is forcing your customers to accept a "No user serviceable parts" license in terms of the software that is deemed unethical

Good point.

> Not being able to inspect the code to see what it is doing may have ramifications for the user -- perhaps not so obvious on a device that has no network, but it is where it starts.

Sure. This connects to data and privacy concerns.

> If I don't give you a binary, then I never have to give you source code.

True of the GPL, but not of the Affero GPL. Also, permissive Free Software licences like Apache impose no such requirements, but are still Free Software licences. Free Software isn't the same thing as copyleft. (Of course, if you distribute binaries but refuse to share the source, then what you are doing is no longer Free Software.)

> It is purely a consumer rights issue.

This makes for easy contrast with the Open Source movement, which is good, but I think it's a little misleading. As an analogy, the right-to-repair movement doesn't expect hardware companies to hand over their design documents, they're just seeking to end open hostility toward third-party repairs.

I fully appreciate Stallman's 4 Freedoms, including Freedom 1, the right to study software, but I'm not sure I'd quite call it a consumer rights matter. Payware proprietary software licenses prevent you from freely copying/distributing the software. Patents and design patents can do a similar thing with hardware. That's not really a consumer rights problem.

To put that another way, I can see the sense in treating Freedom 0 (freedom to run the program as you wish) and Freedom 1 (freedom to study how the program works) as consumer rights issues. I'm not convinced though that Freedom 2 (freedom to redistribute copies) and Freedom 3 (freedom to distribute copies of your modified versions) are consumer rights issues.

EU has almost twice the population of USA and it has several countries with high gun ownership and no border control between these countries and the rest of the EU (Schengen Zone to be exact, but it doesn't matter here).

The crazy high crime, murder and incarceration rates in USA aren't caused by population size. They are caused by inequalities inherent in American system.

It's not like these companies particularly care about the First Amendment, seeing their actions when it comes to things protected by 1A but too icky for their platforms. I expect a blog post(s) to come out of this containing the words "As $COMPANY, we believe the right to freedom of expressing yourself." Bonus points if they include the term "responsible speech".
Thank you. Hopefully sites like this will quickly dry up and die due to the issues faced being stamped out of society.

I agree with what you say. When it comes to things that are as violent as these videos I think you make a subconscious decision. You link the uniform to your views on the matter and unfortunately everybody is painted with the same brush. This is not about an organisation, it is about individuals.

There are definitely not any comments allowed on the site because it wouldn't be constructive. Any discussion around what's in these videos should be kept to the places where change can happen.

I enjoy Reddit when logged in and unsubscribed from all the large default subreddits. I’m always shocked at how different it is when I accidentally view it logged out. The home page feels almost like a piece of carefully curated political performance art in order to somehow get a result allegedly from folks across the nation that is so perfectly aligned with a very specific agenda and advertising platform.

Ask HN: Is there anyone working on 'Uber' for politics
The long delay and uncertainty in measuring the opinion of the people leads to monopoly of few parties, extreme polarization and general instability.

Simple, reliable, fast and anonymous system for voting would help, but unfortunately, it is not possible to have all four. Many would argue that anonymity is the most important feature of the current voting system, to the point of showing bulletins being illegal in some places, but what if importance of anonymity is mostly an artefact of rarity and non-granularity of decisions we vote for?

Now we need extra protection against selling votes, or voters being intimidated, because vote gives very little benefit to the voter, and huge benefit to the elected, leading to most people not being able to correctly price the effects of their vote. If voters had opportunity to decide on every issue individually, the game dynamics would change, and people would be able to protect their votes by themselves.

The software needed for this shouldn't be much more complicated than normal forum/social media app/change.org. The startup would partner with local politicians/small parties/activists to collect and verify the users. Users do not have to pay attention to every vote. They can set their vote to match someone else's, can trade their support for a law with other users, but most importantly they have a real way to influence decisions they care about instead of screaming into void in forms of petitions or costly protests. To do this registered users must to vote on election day, and must provide selfie proofs of a vote where it is allowed, or have votes rescaled by the final count from districts where results are published.

Politicians if elected via app, have to always vote according to the changing preferences of users who have voted for them.

In short this would do to politicians same thing that Uber did to taxists.

I was talking about online multiplayer against (untrusted) strangers. I should have been clearer about the online aspect.

In online PC gaming, cheating is a real problem, as people are able to modify the game to their advantage. This is next to impossible on modern consoles, and cheating is much less of a problem there.

I don't begrudge anyone who wants to opt-in to a designated cheat-based multiplayer session, of course, but it can be a real problem for 'ordinary' gamers.

I got the "everyday millionaire" book, by Chris Hogan (part of the Dave Ramsey 'gang')(haven't started reading it yet). From comments I've read in Reddit about that book, it seems like the vast majority of millionaires mentioned are lawyers/doctors, and you can't become neither without going to Uni.

They guy I was referring to in my post above, started with a certain wealth (even if that wealth is in a form of a 200-sheep-herd), a certain skillset (assisting his father in the business while growing up, having a 'knowledge base' right there in his home, having connections, having the equipment). What has gotten him to a few thousand animals since, is hard work and "invest in knowledge as you go". He didn't start from scratch.

The benefit with his line of business, is that the wealth/skills-handover was happening since he was 10 (experience, skills, knowledge). If one is to become a doctor, the mental training may start early on, but the actual knowledge is coming much later, and at a greater cost ($)(especially in the USA).
A new page will be added to the site highlighting the good that police officers do on a daily basis.

VirtualDOM allows you to roughly code your UI as a function of state. It's never been a magic bullet to better performance, except perhaps compared to Angular.js 1.x's "change detection" methods.
The users will not treat the review information as unreliable, you say. But that is no indication of the information's actual reliability, is it? Like saying an unreliable politician is seen as reliable by the people. Yeah, he fooled the voters. Yeah, he's still unreliable in truth.
Can't do that when their grant money and the possibility of further research depends on being a prolific marketer as well as a great researcher.
React is my UI framework of choice and I don't care one bit about the VirtualDOM or any of its internals for that matter.

I would bet a surprising portion of React's userbase wouldn't even know what the virtual DOM is.
I agree, but also disagree, because many people take this as a literal problem. People think "how can we have self driving cars until they can solve the trolley problem in a way I find agreeable?" but that's not really how the world works. Just try not to hit people. And not just practically in the sense that literal trolley problems never occur. If you find yourself in a situation of needing to choose the lessor of two evils, you're probably just best off believing that absolute morality doesn't exist and you're just going off your gut because that's how you, as an individual human, work.
> the primary aim of programming is to have the programmers build a theory

I don't agree with that statement, but I don't think the primary aim is to produce a program either.

I believe the primary aim is to enable users to use a program. For that they need a mental model. Maintaining a consistent and simple theory among developers is a means to that end.
Correct. I was in the Royal Australian Artillery corps for a number of years, and RATEL procedures (across all corps) drill this into you.

However it is unlikely to occur in practice - the artillery battery will (generally) be on a separate radio net, and the proword will only be applicable if you're in an active fire mission - though it's good to be safe. My wife still gets frustrated with my use of SAY AGAIN.

When you get a good sig on each end, the speed of fire mission comms is a thing of beauty - and once the mission is opened both ends will drop all callsigns.

I completely agree. I would like to set out some defined lines but I have no idea how to go about it. Maybe you can help?

What I can say is that a video was submitted last night of a man who was crawling to a police officer, following his orders, before being shot multiple times and killed. His name was Daniel Shaver. Please look it up and watch the video if you do not believe it is possible to make a judgement as to whether somebody has crossed a line.
That’s certainly a good argument for not using Reddit, but there is absolutely no requirement that Reddit be neutral in the law or in the first amendment.
>Did I miss the text when you sign up telling you that everything you post will be publicly accessible for the rest of time

While reasonable people can disagree on this point, it seems a valid point of view that once you've publicly posted something that's part of an online conversation you can no longer unilaterally delete it.
The emotional rejection experienced by the moderated user might be less when they associate that experience with an automated tool/bot rejecting their posting versus a human.

It's possible that a moderated user might feel less dejected when they know it's not a human personally reviewing their content and rejecting it.

Certainly I myself would feel less inclined to try posting again if a human moderator rejected my content (because I feel that I have little chance of changing their mind, and I'd feel judged) whereas I'd be inclined to try again if a bot rejected my content because it's impersonal. This is, of course, entirely irrational since automated tools can't really be persuaded in the same way a human can.
I've seen many people discuss how this ruling could kill small internet communities. Curious how people would react to simply making a separate class for excessively large websites that are effectively public spaces due to scale and likelihood of frequent encounter.
This doesn't seem like a European norm to me, maybe it is done in German but I don't see it in English or French publications.
I would be more than happy to send you the code for the site if you wish to set this up. Personally I feel like police generally do a good job of handling cases of brutality against them.
> Saying that it may be true is accepting the possibility :)

Only if you completely ignore the other part of that same sentence :)

> This I have to confess I don't understand. The site is trying to answer that exact question, and their answer is "racism". Now, they may be wrong, but I don't see how it's another issue... what issue are you focusing on, then?

Think I covered that in my original comment (and the subsequent ones too) - was just not convinced that "racism" is the correct answer and questioning the reasoning behind it.

After downloading the DB and deselecting "Allegedly Armed" there are 281 records so only 1/4th.

Not being US resident or citizen I wonder if this is the effect of the gun availability.
Just few weeks back I was listening to a podcast where one of the guys went to US for couple weeks for vacations. They discussed the difference of the approach of the police.

Where I am, it's usually silly, when cop stops my car he salutes in overly formal way and in really angry tone (like really really angry) described what I have done and if I comply if not. Probably 99% of the danger for the cop him/herself is that I'm going to curse him and his family 3 generations back.

Whereas in US, it's all about police-safety first. They will scan back of the car, will ask (demand even) absolute compliance. This makes sense (to some degree, as police person is protecting their own life) since I could have a weapon and be a criminal or maybe even insane enough to try to pull this stunt. After living with this possibility for a while and having to estimate situation dozen if not hundreds time each day it's not surprising that police killings do happen.

613 of those 1089 killings in 2019 (56%) were gun related. And that's 75% of the "victim armed" cases.
In contrary only 119 victims were confirmed to be unarmed.

That's probably something completely different than the authors wanted to communicate, but I think it shows how complex the matter is and undoubtedly can't be attributed to only single class of the issues.
People always forget that the Bill Of Rights is about the relationship between the Federal government and the people within the US. Applicability to the relationship between businesses and the people can be extended by Congress and the Courts but is not the reason the Bill Of Rights exists.

> But you have to avoid generating nitrogen compounds

What if we reverse the polarity on the main deflector dish.. I mean emitter wire?

> The effect is not directly dependent on electrical polarity, as the ions may be positively or negatively charged. Reversing the polarity of the electrodes does not alter the direction of motion, as it also reverses the polarity of the ions to match. Thrust is produced in the same direction, either way. For positive emitter polarity, nitrogen ions are the main charge carriers, while for negative polarity, oxygen ions are the main carriers and ozone production is higher.[citation needed]

Of course, Reddit has the right to fight for free speech while at the same time suppressing it on its own platform, or at least tolerating the suppression of a free discourse in the most popular subreddit. But doing so makes it seem reddit cares first and foremost about its own freedom, and less about freedom of speech in general. It also means reddit is a poor choice if you want to run a forum that leans conservative.
In hindsight, what do you think lead you astray? Curious if you took an academic route, associating more education with greater skill or just focused on the "wrong" thing?
