skysight-inc/HackerNews huggingface dataset:
The minute ("small part") and second ("even smaller part") come from the era of clockmaking as they were pointless when your timekeeping resolution was crude.* We are quite lucky that hours and then minutes were divided into 60 sections rather than 10, 12, or 100. This may have come from the system you describe (arc minutes, seconds, thirds, etc) which is much older.

* or not just crude but completely different; e.g. Babylonian and Roman hours varied in length each day as the time from sunrise to sunset was divided into twelve equal sections and sunset to sunrise implicitly the same. IIRC the constant-duration hour goes back only to marine navigation a few hundred years ago
I don't understand "WebRTC doesn't support it". What do you mean?

WebRTC uses an external signalling channel to negotiate ICE candidates, codecs, and necessary information to establish a media communication. Once this is done, the visio/audio conference is P2P and encrypted from the caller to the callee: how is this not E2E? (Genuinely curious, not criticizing)

That is, if you're not using a TURN relay server, which is easy enough to know.

Maybe you meant that multi-party (one-to-many or many-to-many) calls are not E2E. Again I'm not too sure I understand: it is possible to have multi-party conf calls: each participants can encrypt its media stream and send it to the N-1 other participants. Obviously this costs a lot of CPU (for multiple encryption) and a lot of uplink because the same stream is sent N-1 times. But it is __possible__, and certainly viable with only 3 or 4 participants, provided people have a decent connection (WebRTC uses adapative bitrate streaming [0] to compensate for bandwith usage).

Then again, I know that generally, with WebRTC people would use MCU [1] when dealing with many-to-many conf calls, and then I agree it breaks E2E.
But for the other mentioned cases, WebRTC is E2E, isn't it?

Again, I'm genuinely curious about this, not trying to criticize or undermine.

Thank!

Ah, measures of angle. One of my favourite is the Warsaw Pact Millirad, of which there are 6000 in a full circle, a full 6.25% less than the 6400 NATO mils.
Ah, it's nice to hear that Duo does e2e, thanks.

And if you actually are experienced and try to offer a newcomer some guidance in writing code that they won't regret having written a year from now, they'll accuse you of being a "perfectionist" who's wasting time trying to obtain some theoretical optimization.
These articles both seem to summarize the same set of evidence, and it primarily consists not of studies where it doesn't work but evidence that Mr. Raoult is untrustworthy. Which he does seem to be, don't get me wrong, but that's very different than affirmative evidence it's ineffective.
Legitimate question. There's certainly precedent.
China has a comprehensive surveillance state that has fallbacks for cases when masks are not available.
Ok, if you feel things are still in such a good shape, great for you. At my distant vantage point, it seems it could be difficult to keep up with all the ways the WH (we do not speak its name) is or could be interfering with just about anything it has a tangential interest in.

Also your reassurance hinges on that every federal bureaucrat would complain to media in every circumstance. From my experience of bureaucracies you have to pick your battles and resisting or leaking is not always in the cards if you want to keep your job or career prospects. ("Live and let live.")

I have tried something similar 5 years ago using the meditation device from choosemuse.com. It was the cheapest option and provided hackable interface that you had access all the data. Then I wrote a small mobile app connects to headset.

Application was picking and showing a single random word from "hello world my name is hrgiger" then showing a greeen light, when I see green light, i think about the word and blink, headset was able to detect blinks as well so app was creating training data using blink time - xxx millis. So I created few thousands training data with 6 class using this and trained with my half-ass nn implementation and used generated weights to predict same way via mobile. Never achieved higher than 40%, tried all mixed waves, raw data, different windows of time series. Yet still it was a fun project to mess with, still I try to tune this nn implementation. If they achieve a practical solution I would use subtitles for the full length training. Simple netflix browser plugin might do the trick,but I am not sure if there will be a single AI algo that would understand everyones different data.

Is this not exactly how React also works?
I think it's interesting to see the outcry when Apple poses new restrictions in the application distribution process (like signing and sandboxing) but conversely the same cries go up when there is an App that seems to be abusing loose control mechanisms.

I think a lot of power users rightfully feel they are belittled by sandboxes and application restrictions. But seeing that they are not the major userbase and most Apps don't really need any permissions at all for their intended purpose (the user's purpose at least) I think Apple is moving in the right direction.
You always use that red herring tactic, rather than make a cogent argument--mainly because I don't think you have an actual argument but rather sensationalist knee-jerk reactions masquerading as one--but look below: I actually outlined how and why I think it is a system can actually combat the very pitfalls I listed with current features.

Will corrupt actors use this technology to steal/scheme, sure, of course that much is inevitable of any technology; but condemning the entire protocol and aggregating them altogether as a collective failure because of that is about as useful as saying the Internet should be seen as nothing more than a den of thieves, child pornographers and counter-fitters: when we clearly know it is much more than that.
Just an FYI, two weeks ago, CMS announced it would be suspending enforcement of telehealth tools used in good faith during the COVID pandemic. [0]

Basically, if you are a family doc that's been thrown into the telehealth ringer, you can get started with everyday tools for video chat, like Facetime, Google Hangouts, Skype, etc - regardless of that tool's Hipaa compliance.

Overtime I do expect they'll want to see providers transition to compliant solutions, but they understand thousands of doctors, some of whom have never delivered telemedicine, can't simply audit and on-boarding a new provider overnight.

Meh, I'll take the bait.

There are no fundamental new ideas in this paper compared to the preceding papers. What they do is to tune hyperparameters (BPTT length, exploration/exploitation tradeoff, and policy parameterization) in a smart fashion as to fit the bottom 5% of Atari games. Obviously the parameters, or equivalently, architecture choices, are tuned to achieve exactly that - good performance at the bottom 5% of Atari games. None of these choices will generalize outside of this specific set of Atari games.

The reasons we are doing badly at these games are well-understood. They typically require "world knowledge" (what is a key? what is a door?) and reasoning (I found a key, that can be used to open a door). That is, the visual representations need to encode such knowledge. Algorithms don't possess this world knowledge as they are not embodied in our world, so they need to learn it from scratch, i.e. brute-force it. That's exactly what this paper is doing - brute-forcing the solutions by finding just the right hyperparameters with millions of hours worth of compute.

A good analogy is what would happen if you took the game but flipped the pixels in some deterministic way so that the screen would look like noise to a human. A key would no longer be a key, but the structure is still the same. If someone asked you to solve Montezuma's revenge with that representation, you would not be able to. Does that make you stupid or non-human? So, because these games require human world knowledge, solving them in the same way as simpler games is kind of besides the point.

Man, what is going on with Participant C's active neurons.
I used to work in video and if I remember correctly there were I, P and B frames. You need I and P but the B frames are optional. So if some meta data is unencrypted the server can tell which packets are B frames and decide not to send them to slow clients. The actual data is still encrypted.
Doesn't everyone have enough in savings to survive a year without positive cash flow? If not, why not. Health care is tied to your job in the US? That's just crazy talk. (I believe you, but it's crazy from my perspective, which is someone living in the middle of Europe.)
Not good reason. Lying to people to try to manipulate their presumed stupidity for their own good doesn't work. We went through this with the malarkey around claiming "advising abstinence is safer than offering condoms for STD protection"
That’s my point, you should not have to sign in. Not to read articles about a world-wide pandemic. Normal stuff, sure.

The X in X-Planes stands for "eXperimental". The history of them goes back within the US to 1946 and as the list [1] of vehicles shows, these aircraft are intended to test concepts and ideas, not provide a sellable solution to the market.

Whilst most are betting that commercial electric in the air is going to be VTOL - and they do address the low endurance and runway issues you highlight - there are efficiency gains for longer distance in fixed wing designs, and you're going to have to think about electrification of that class of vehicle at some point.

Put another way: we don't use helicopters for all passenger transport for a whole bunch of reasons, EVTOLs don't fix all those reasons, and so if you want to keep fixed wing aircraft around as a concept AND you want to use electric motors, at some point you're going to have to think about experimenting with electric passenger-carrying fixed wing aircraft.

Thus: the X-57.

You might wonder what the purpose of an experimental aircraft in this config is, if the eventual goal is to build airliners that can move lots of people.

Well, the X-1 was no Concorde, but Concorde would not have happened without the X-1. And so it goes...

It's OK then to think of the X-57 to an airliner of the future, as the X-1 was to Concorde. It's a whole set of interesting experiments that will validate some hypotheses, refute others, and we move along another step towards a better future.

Seat count will get higher, endurance will improve, batteries will get lighter, and within 20 years, who knows where we'll be.

This is a good essay, and I think one of the main lessons is that programming is a small part of software development.

The question of whether to use an inefficient, readable implementation or an efficient, cryptic implementation can mostly be solved with the correct class topology. If classes are SOLID, then it is easier to justify a cryptic implementation of one method as that is hidden from most other developers. A class that will be inspected by others more, such as a business logic service layer, should lean towards inefficient, readable code.

Likewise, the question of whether to reuse or roll your own can also mostly be solved with a good architecture. Logically separating components makes it easier to tailor the implementation to the use case, and replace if necessary.

As always, breaking the problem into smaller problems is most of the battle.

Sadly software development as it is taught and measured by interviews, is mostly about programming and algorithms. The real art and value in software development is interface design and system architecture design.
I like what you said in the first line.

Personally, I'm less interested in the 'management' aspect of this topic, and more interested in the "process" or the idea, so to speak.

I think supply chain is a big idea and a big topic in itself, and how you manage it, when put in charge of human labor, in only one part of it.

And I think there is some relation between 'supply chain' and 'concurrency' in CS.
Japan may be an exception to that general rule. Most places, sick people go to the hospitals and die there. In Japan, sick people stay home, die, and are often only discovered a long time later.

https://en.wikipedia.org/wiki/Kodokushi is the Wikipedia article on it. It is hard to get statistics on it, but in 2006 close to 5% of all funerals in Japan were old people who died at home that nobody knew about for some time afterwards.

When all is said and done, Japanese will be discovering bodies for years afterwards. Not just because there is a crisis, but because that is simply how a lot of deaths happen in Japan.

If you are living paycheck to paycheck and don't have enough funds to survive a year without positive cash flow, you yourself are to blame for your misfortune. If you got the money to buy a phone, you got enough income to save up and not saving up was a personal decision. You reap what you sow.
Not quite, because if react is re-rendering a component it re-renders all its subcomponents as well whether they've changed or not - the DOM diffing stuff means it won't screw with the DOM for stuff that hasn't changed, but it still has to regenerate it to find out.
Hipaa has additional restriction/controls for psychotherapy notes as they are considered highly sensitive. I'd expect this is the same line of thinking in Germany.

Discussing your heart disease or skin condition is sensitive, but it's not as sensitive as discussing deeply personal thoughts or inner monologues.
Certainly a headline I'd never of predicted seeing in my lifetime.

However, currently they recycle urine into water. So whilst this may work, you would be needing more water to produce more urine.

What I've always wondered is, old satellites, they often get put into an abandoned outer orbit, why not crash them onto the moon for later use/recycling. Though equally mindful that some have unfriendly power generating inside, so that may preclude such avenues.

I've been thinking about that — after all, Reddit with its concise design, is pretty nice.

I'd want there to be an optional concise theme, so Talkyard could look more like HN or Reddit, for those who prefer that.

> fold all sibling messages before the one that I'm interested in

Where could be a good place to place a Fold-all-siblings button? There is a Fold-whole-thread button already at the top of each post, to the right of the author name (it looks like: ^ and to un-fold: v ), ...

... but if one has scrolled down a bit, and want to fold all siblings, when the parent post is a bit away, then, could be impractical to have to scroll up to it, and click a button up there?

Maybe clicking the arrow could open a power user menu, with "Scroll to parent" as the default, and also a "Collapse siblings" button?

Example: If you go here: https://insightful.demo.talkyard.io/-9#post-24 and click the arrow to the left, maybe this poweruser popup menu could open?

And / or you have other ideas? :- )

Please find a word that means "an ordinary piece of fabric that you can build yourself and wear if you're not sick".

At least in France, "Wear a mask" would be understood as "wear an FFP2, surgical-level" mask. The kind of masks:

* that we are in very short supply of at the moment (for various and sad reasons)

* that we have to save for doctors

* that everybody would try to buy on black markets if you asked them to use

* that we unfortunately told people not to try and buy (precisely because we need to save them for doctors because they are in short supply, etc...)

So if a campaign started today saying "wear a mask", with the intention of saying "cover your mouth with a piece of fabric that you made yourself if you're not sick", I suspect it would be counter-productive.

We need another word.

Ask HN: Successful one-person online businesses in 2020?
This was asked last year by gajus (https://news.ycombinator.com/item?id=21332072) but I am curious what the list looks like now considering the current global climate.

Anecdotally in my own circle, the people in eCommerce are the most successful and doing almost black friday sales figures on a daily basis for the past few months at least. Not to mention, profit margins are higher since this is minus the big discounts one usually offers for that day. The ones with SaaS/services are a 50-50 split and generally speaking, the consumer & small business facing ones are seeing huge spike in churns where else the remote work related service ones are seeing double digit growth.

Note, definition of successful one-person online businesses remains the same as prior threads:

> How many people on hacker news are running successful online businesses on their own? What is your business and how did you get started?

> Defining successful as a profitable business which provides the majority of the owners income.
This is really moving. A fantastic blend of storytelling and technology.
Ask HN: What does end-to-end encryption mean?
Mobile, apologies for formatting.

I was reading Zoom's security whitepaper on their website and it says it can "encrypt presentation content at the application layer". Now I have a reasonable understanding of E2E encryption, but if the text or content has to be presented to the user by the OS, can the OS read the content of whatever the user is seeing since it has to render the graphics?

For example, can Google read my Signal messages via the fact Android has to render the text?

JavaFX seems like it was a good incremental step over Swing but right at a time when the web’s paradigm (the DOM, a brilliant concept) was becoming popular and was a leap beyond Swing. So JavaFX has the same problem as Windows Vista: too little too late. If we had something like the DOM as a new UI kit, it could be a big hit if done right.

This could work out pretty well.

Regarding the ranking: This post is currently #1 on the front page.

It was posted around 08:00 UTC. In my experience it is generally very hard to get traction for a post that is posted before ~14:00 UTC. This is a site with lots of US users, and it’s still early on the west coast (07:18 PDT).

This post managed to climb to the top despite that, probably because Zoom is a company that is interesting to techies, the article is from a well-regarded news source (at least in this crowd), it covers misleading marketing, it’s a bit related to Covid-19 and it also touches the topic of E2EE.

To those who think this is bad: why? What is the downside to trying this, or at least manufacturing a stockpile, that all of the health officials seem to be missing.

Essentially: if you could talk directly to the FDA, what new information would you give them that would cause them to reverse course on this? Same question for any of the countries who have made this a part of their standard treatment. What do you know about this that they don’t, why are they wrong to have done what they are doing?
