Fiber can also have asymmetrical speeds (see GPON, NGPON2 etc.). The issue is not the media per se but the concept of shared media. Take any media, wireless, coax, fiber, even copper (ADSL) you have X amount of spectrum to work with so you have to decide how allocate said BW. Since most users demand is higher for downstream than upstream (typically you are downloading a lot more than uploading) it makes sense to allocate more to downstream. Of course it is possible to have full duplex symmetrical speeds. Say you want to allocate 2 fibers, on for upstream and one for downstream, then you can have symmetrical speeds. But typically due to costs, you want to have one fiber shared between a large number of users (e.g. GPON or NGPON, aka FiOS) or one coax shared amongst many users, or some set amount of RF spectrum, in any case you need to make the same type of trade off choice that the cable provider makes or that the DSL provider makes or wireless providers. In the case of wireless the reason that uplink is so much weaker is due to the limited power of the user equipment, also smaller antenna etc. refer to Shannon's law, uplink will be weaker. But generally speaking, it makes sense to have asymmetrical speeds unless you have the luxury of having the same spectrum and power available for both directions.

GPT2 does learn, right.

I wonder how much of our knowledge of math is self-attention and how much is something else.

For example, much of what I do when I do calculus is mostly self attention. When I solve a calculus problem, I generally don't think through the squeeze theorem, but apply cookbook math.

My current model for the brain is consciously driven self attention. Ie, 80-90% of what we do is just self attention and our conscious brain checks to see how right/interesting it is around 10-20% of the time.

The key therefore really is training your brain on the right data.

This model I find explains quite a lot of things about people and the way they behave / succeed.
I believe that's a reference to Tony Hoare's famous talk about the invention of null references which he calls his billion dollar mistake

It seems you'd also be able to isotope-label fertilizer.

That just leaves the pesticides...
GPON is both time divided and frequency divided.

There are typically 3 wavelengths.(frequency division). Two for data(downstream and upstream) and one for video (downstream).

The downstream channels(both video and data) are broadcast and not time divided. The streams are filtered by the ONT. The upstream data channel is time divided to permit multiple devices transmitting without collision.
If a previous industrial civilization put satellites into geo-stationary orbit, they'd still be up there. If there are unknown objects in geo-stationary orbit, would be be able to find them? If we could find them, and we haven't, doesn't that put an upper limit to the technological sophistication of possible previous industrial civilizations?
You can have your opinions but this is not how marketing or sales work. It isn't some new tech. This is age old stuff that has been going on since humans started trading. You always, always dumb it down even for your potential clients. The reason is more to do with cognition than to do with the client's knowledge. Your brain is not always focused on everything around you. It is more psychological. You are thinking in binary (or in other words: logically). The brain is more complex than that. It can sometimes fail to do the simplest of tasks but at the same time be capable of solving the most complex of problems.

The idea behind a tagline is to capture the user's attention. You can build up on the complexity as the user goes further down the page. But to start with a complicated tagline will cause your users to quit.

If someone is selling mangoes in a market and he shouts "Mangifera Indica for 5$" will people purchase from him? He is still selling Mangoes and dare I say he is more accurate (because the scientific name for Mango is Mangifera Indica). His potential customers will be those who are botanists because only they understand the scientific nomenclature. But those won't be his real customers too. What if the botanist hears the scientific name but his/her brain ignores it as the brain triggers only in certain environments (like in a lab)? What if the botanist is not interested in Mangoes even after understanding it? As you can see, your potential customers are narrowing down with every filter applied. This is exactly antithesis to "selling to as many as possible".

But if he shouts "Mangos for 5$" he attracts everyone interested in a Mango, including the botanist.

And I don't want to sound nasty but no technology is so advanced that it cannot be simplified. Also don't forget that people can smell bullshit from a mile away. That is what I have learnt from experience. We Engineers like to overcomplicate and overpromise stuff that will only come back to bite us later. Just follow the KISS principle: Keep It Simple, Stupid.
Agreed that it is not so simple a calculation. However, I still don’t think you should commit fraud just because you think the calculation is complicated.
I suspect this. Also note that spell checking won't detect it; you won't get a helpful red underline to warn you.
The "farmers" backing the EPA rule change are the industrial CAFO operations that produce open-air manure lagoons (literal lakes of shit) that cause all kinds of environmental hazards. They can afford to care less because they typically don't live on-site like traditional farmers did. Hell when it comes to hogs they might not even be citizens - the largest hog producer, Smithfield, is owned by the Chinese now.

If you can find an actual farmer - an endangered species as the industry consolidates into corporate CAFOs - I can promise you that they have no interest in drinking poison from their wells.

This is why I created doodledocs.com

It is a humble prototype [1] for: what if the web was simply made of paper and you have a stylus?

Collaborative drawing

Drawing over websites

Drawing over images (and making them transparent)

Those were important features I came up with.

Currently I’ve noticed the following by using it that it helped me as follows:

- it is super easy to talk about websites because you can draw over them and circle things and so on.

- By line drawing images and playing with the transparency of my pencil, my drawing skills improved

- It has been the quickest way to communicate about math if you also use voip with another program

[1] While I find it transformative, it is that just a little bit. Also, it works best in Chrome and since my implementation of webrtc is totally free (no TURN server), it doesn’t work with corporate wifi. Also while collaborative drawing should work quite well collaborative web annotation is really buggy (you need the same viewport).
Yet people use 3rd party VPNs that do this all the time in the guise of security & privacy.
The recommendation is highly sensitive to who you follow. Many of the long-time users have a great feed, but starting out with a clean slate presents rather poor results.
> What culture eats bats?

> It’s not a Chinese thing. So which ones do?

Upvote for asking without animosity. I appreciate you.

Since you asked,

> Bats are a food source for humans in some areas. Bats are consumed in various amounts in Seychelles, Indonesia, Vietnam, Guam, and in some other Asian and Pacific Rim countries and cultures.[1][2][3] In Guam, Mariana fruit bats (Pteropus mariannus) are considered a delicacy,[4][5] and a flying fox bat species was made endangered due to being hunted there.[2]

Just to support your argument further, here is a related snippet from another comment[0] by knzhou:

> Students can all recite Newton's third law, but immediately afterward claim that when a truck hits a car, the truck exerts a bigger force. They know the law for the gravitational force, but can't explain what kept astronauts from falling off the moon, since "there's no gravity in space". Another common claim is that a table exerts no force on something sitting on it -- instead of "exerting a force" it's just "getting in the way".

Here is some food for thought for educators. If GPT-2 also makes sense of the world by regurgitating what it sees, perhaps this is simply the nature of learning by example, and we should accommodate for this. Perhaps it isn't so effective to give students mounds of problem sets offering clear premises and easy-to-grade answers. Unless you want your students to be GPT-2s.

Not sure if it would be this, but autocomplete on some platforms sometimes happily replaces a correctly spelled word with a different word it incorrectly assumes makes more sense contextually, and you won’t notice it happened unless you’re paying close attention as you type.
funny thing about that, some time ago I tried to figure out how to stop all messages from fbook to my email, after menu hopping for some time, I allowed my gf to go into the settings and turn it all off and turn on many privacy settings.
I know fbook has changed the privacy things several times since then, but I don't use it enough to have any issues I think.. I also don't use messenger app or fbook mobile, so I've gotten lucky (and helped) to get zero messages from them for years.
Not all industrial civilizations launch geo-stationary satellites.
Thank you for saying this. This is something so many people miss when trying test the limitations of GPT-2. It just doesn't make sense to test it on strings of text that nobody ever writes.
My understanding is that I would expect there would be some left, albeit maybe more debris after their orbits slowly become more erratic (not as coordinated regarding other satellites) and collisions and failures occur.
Who knows what they were referencing, but there is a site of a “natural nuclear reactor”. They could have built a lot off that.

Increased carbon levels are found in ice deposits from the period of the Roman Empire. There's nothing prior to that.
This sounds like an incredible science fiction series that needs to be written.

Any chance such books already exist?
The same could be said for plenty of meats, e.g. lobster ("who would eat these bottom-feeding saltwater cockroaches voluntarily?"). Different cultures can simply have different norms, and even where it's not normal, poor people will eat whatever is available and rich people will eat whatever is a curiosity.

This is a terrible argument. Our personal lives and digital lives are becoming amalgamated to an extent never seen before.

Our emails, for better or worse, are mainly handled by private companies while giving the importance of physical addresses.

We can't expect everyone to understand the nuances of this and should protect them from abusive practices of private companies. E.g. You should be able to keep a readonly email even after getting banned so you can slowly move off of it.

Google shouldn't be able to just wipe out a good portion of your digital identity through an algorithm or a press of a button.

Maybe this sort of legislation would make them double think their business decisions and if they want to stay in this business. I suspect they would, email is a massive part of their industry footprint.
>The current area of urbanization is less than 1% of the Earth’s surface

But doesn't this assume cities are distributed uniformly and randomly? Cities seem to be build at ports (ex: Port of NY, Oakland) and waypoints with natural resources or barriers (Salt Lake City, Denver on either side of the mountains for example)
No. Rules alone are not enough without moral character on the part of the reporter. Lehrer showed moral character in proposing the rules, and even more in acting on them in a consistent manner. But without the moral character in the reporters (and their managers), the rules are just wallpaper.

Prime is sold for a non-zero price, so it generates revenue.
No. Process tech is profoundly correlated to cpu performance. It’s literallly the definition of Moore’s law. Intel has no 10nm server processors. Intel’s near 5 year delay in getting past 14nm has opened a huge window of opportunity to competitors both AMD and amazon/arm. It is highly worth comparing these competitors apple to apple vs Intel’s oranges.
This sounds familiar. I was an international-level rower for about 8 years when I was younger, and my training regimen was a mix of extremely intense HIIT and long (45min+) steady state workouts.

Near the end of my career, I began suffering from very noticeable PVCs (premature ventricular contractions) whenever my heart rate would drop below 45bpm — that is, any time I was at rest, or trying to sleep.

My EKG showed mild bundle branch block and echo showed moderate left ventricular hypertrophy. General consensus amongst the cardiologists was that, as long as the remodeling could be explained by exercise, they had no concerns.

That was about 10 years ago now. I am far less fit today, and the symptoms described above have largely resolved. My echo shows a mostly-normal LV wall, and I haven’t had a skipped beat in years.

That said, this recovery happened during my mid-to-late 20s. Not sure how this would have gone 20 years later.
They will be somewhere around Earth. But not on the orbits they are now. They won't be hard to spot.

I guess the most pressing evidence is that nobody used the fossil fuels before us (at least in large quantities), and a lot of it is from the time that plants first colonized the dry soil.
I don't understand why Quora had so many employees. I don't intend to harsh on them: I literally don't understand their business.

To my naïve understanding: they have an authentication system, a moderately high throughput CMS with a search engine, and...? + User-generated content. OK, some DevOps people, some people who negotiate with the CDNs. They seem pretty snappy so some serious work presumably went into the back end, but still. WhatsApp had only 50 people!

What am I completely missing here? why did they have 200 people?
On the millions of years scale, that signature disappears.
I'm fairly sure this is why I do it. I'm an average typist and above-average speller, but -ion spills out whenever I type it. There are almost no words ending in -io, and there are a lot ending in -ion. For some quick numbers, the OSPD database I have here has 1432 -ion words and only 47 -io words.
Lots of thoughts already on this page, hard to focus a discussion but I'll try to get to the essence.

The mnemonic medium tool is fantastic, it forces our brain to keep an idea current; we tend to naturally forget stuff if it isn't necessary to our survival. That the software "knows" when you're about to forget something seems to be what's novel here.

The tool is always paired to an individual though, so I bet this will have to be personalized down the line.

What do I need to be reminded of at time X?

As for the What... I feel like I can only learn one "neural diff" at a time. Which one totally depends on what I already know: some times I learn nothing, other times there's too much new information unrelated to anything I already know. Ideally the tool would know what I know, compress a whole essay, and "program" me with a story composed of something like the following operations:

a) add a new connection between concepts you previously thought unrelated

b) change a connection between two concepts, they are not related how you thought

c) insert a new concept

Of course the hard part is knowing what I already know, but I could tell you.

PS. This whole ordeal seems to be related to what good teachers and advertisers do: first get to know the audience, then tell a story with good rhythm and spacing.

PPS. The key to augmenting our thoughts with technology is trust. Our nature requires our brain to keep us alive. We can learn to externalize thought processes, yet if that externality can't be trusted, our instinct will be to unlearn our connection to it.
I doubt the accuracy of this fingerprint.

It claims my user agent (the latest stable Google Chrome - default browser - on a stock Umidigi android device) is unique.

Interesting idea and covered many times before on HN including at the time:

> Note that 39 bpm is sleeping

Are you comparing this number to resting heart rate values in literature? Lowest recorded HR during sleep and the value people are talking about when they say "resting heart rate" are very different things.

(Just double-checking possible confusion, because that story about the primary care doctor suggesting to cut down exercise seems really odd. Did you perhaps give that "while sleeping" number to your doctor as a resting heart rate value? That would explain a lot)

The Mojave Phone Booth
Neil Ferguson, an epidemologist at Imperial College, suggested that the 2019 novel coronavirus’ Basic Reproduction Number (R0) [1] is about 2.5, which aligns with figures from other research groups. The 1918 pandemic-causing flu’s R0 was between 2 and 3 [1] while seasonal flu’s figure is only 1.3 [2].

This is not to say everyone should panic as the strict containment policy that China and the Chinese adopted should help reduce the R0 significantly. However, the asymptomatic period is long, thus it remains to be seen what the full impact of this virus will be.

Other countries may need a better policy to track high-risk individuals already in their territories.

“Neil_ferguson
@neil_ferguson

R0 estimates for flu pandemics lie in the 1.5-2.5 range. Yes, Measles is much higher (10-15). An epidemic with an R0 of 2.5 could still infect between 60% and 90% of the population, depending on contact patterns and assuming no prior immunity. Not all might be symptomatic though.”

Nobody has time to read all the facts.

Nobody has time to report all the facts.

Nobody knows ALL the facts.
In that exact same book by Carl Sagan he uses the quote:

> Appeal to ignorance—the claim that whatever has not been proved false must be true, and vice versa (e.g., There is no compelling evidence that UFOs are not visiting the Earth; therefore UFOs exist—and there is intelligent life elsewhere in the Universe. Or: There may be seventy kazillion other worlds, but not one is known to have the moral advancement of the Earth, so we're still central to the Universe.) This impatience with ambiguity can be criticized in the phrase: absence of evidence is not evidence of absence.

Carl Sagan says we should be comfortable with ambiguity. We should say "organic food might be healthier, or it might not, we don't know".

But I already linked one study that seemed to indicate a health benefit.

I don't see how "The Dragon in My Garage" is relevant here. In that story, the goalposts are constantly moved until the idea is untestable. But the idea of organic food being healthier doesn't seem to have moving goalposts, and it doesn't seem untestable to me.
https://en.wikipedia.org/wiki/West_of_Eden

and many others :)
They do. It is not wise to infer controversial information from ambiguous journalistic language. I typed "us organic certification cost" into google, and it helpfully quoted this at the top of the page [1] :

> Certification costs vary depending on the size of your production operation and on the accredited agency you choose to use. In general, organic certification costs run between $200 – $1500. Your costs will include an application fee, site inspection fee, and an annual certification fee.

I humbly suggest you might have taken a moment to check if your hunch was correct rather than leaving that to others.

Also its not possible for tests to confirm if produce is organic, but it possible to confirm it is not - if it contains traces of prohibited pesticides which are routine in non-organic produce then its not organic.[2]

IIRC, it was somewhere around the India/Pakistan border. Ive seen the episode, but its been a while.
Had a similar situation with my mother's iPad and Yahoo. YahooMail wouldn't allow a password change because my mother, having suffered an injury, moved and gave up her landline phone number, and had no alternative verification mechanisms set up. The native iPad mail app still connected via a cached credential, but those credentials can't be backed up. The iPad power failed sporadically, so she lost contact with people, with no way to transfer credentials to her new device (on the rare instance the iPad would briefly start), and no way to reset the YahooMail password. The only solution I heard that might work is to buy a paid yahoomail account on her behalf (assuming there's some way to verify her identity) and see if someone in support can get her back on the right track so that she can keep getting her spam and point anyone contacting her to her new address.

I hope this stuff gets easier before I get to my 90s.

So what is your point?

That because a food source is considered by some people to be a delicacy means it’s racist to suggest that eating it is unwise given the public health risk?

Foie Gras is banned in CA because it’s produced inhumanly and consider cruel. Is that action a form of racism against French culture?
Yup, compare Google and ddg, or Facebook and every decentralized network.

One of the papers mentioned in the linked discussion shows that the number of As can vary over time within a single patient. There seems to be some evidence that different lengths might give an advantage or disadvantage in replication, but it seems like variation is normal.

That's probably one of the main reasons: to be able to announce such low prices, even if at extremely limited quantities
> To prevent law enforcement from getting their hands on the special phones, Phantom Secure required existing customers — referred to as “executives” — to vouch for new customers, then conducted background checks. The company’s safeguard didn’t always work.

In contrast, anyone (including law enforcement officials) can buy a PinePhone, and I doubt Pine64 is laundering money. It is unlikely for Pine64 to be prosecuted the way Phantom Secure was.
