Thank you for the explanation!

It's difficult with academic researchers using terms with significantly different meaning from the public at large. I wonder whether it's more harm- than useful, as it'll typically lead to the public either misunderstanding what they say or dismiss them completely because they're "obviously talking nonsense".

The scientific research into echo chambers seems almost straw-man-y, e.g. "echo chambers are perfectly sealed to the outside, no contact whatsoever is possible", so they check and find "that's not really happening" because people might talk about politics with one group exclusively, but will also talk about sports so they're not in an echo chamber. Does that provide value, when they are in a political echo chamber?
I m 26.Six years ago in my high school i fell in love with a beautiful and intelligent girl.It first started with being friends.But gradually we fell in love and I was attracted to this girl like nuts.But we broke up within 4 months.Within those 4 months we formed a very intimate relationship except being physical.It was a very traumatic break up and i tried all sort of things to get her back but nothing worked out.I went into depression.I may sound like an awful person but I think that i will never get another beautiful girl like her in my life ever.I feel like a loser.I lust over her obsessively.I cant move on with my life.I have blocked her from my Facebook page but i just couldn't imagine her with someone else. until i meant a testimony of a lady on the internet call Alice who testify how prophet Egwonga helped her to get her ex back so i decided to contact prophet Egwonga via email: greatpriestegwongatemple@gmail.com and he told me what to do and i did it without wasting time and in less than 24 hour my ex called me and begin to beg for my forgiveness and we settle our difference and today we are happier with each other and i'm advising does who are in any kind of problem don't lost hope all hope contact prophet Egwonga via email: greatpriestegwongatemple@gmail.com and you can also whatsapp him directly +44-7727-704231 for his immediately Response

Legal Tech VC Funding – Outlook Bumpy, but Some Optimism
Scientists find new paradox: vibrations can grow without external influence
You raise some points that were also raised by a sibling commenter, but I’ll try to reply to them. You are correct that FB and EC are different concepts that are unfortunately often used interchangeably (even in research). This stems from the fact that there was no robust definition offered when the concept was introduced. Bruns offers a definition to distinguish the concepts.

> The former is passive, and you have no choice. The latter is human nature. Birds of a feather and such.

Both concepts are closely related to the idea of homophily, the preference to connect or communicate with like-minded individuals (birds of a feather, as you say). In Bruns’ definition, echo chambers mean the preference to connect, while filter bubbles mean the preference to communicate. Both of them are, as you say, human nature at their core. The concepts go further than homophily, though, in that they also exclude individuals or information outside of the chamber or bubble.

> "Appear to encounter" is a vague.

This is from the research abstract summarising recent empirical findings. I think some critical distance is warranted.

> Thst aside, encounter doesn't mean you're open to those ideas. (…) The exposure doesn't open their mind, it backfires and pulls the blinders even more narrow. I missed where this study addresses that boomerang effect.

This effect is addressed as a “oppositional reading stance” in the section “Social and Political Relevance and Impact”.

> Again, "exposure" isn't necessarily leading to more diverse ideas.

You are correct. However, if individuals are encountering information contrary to their bubble’s or chamber’s belief, we would have to conclude that there is no FB or EC at work as it has failed to exclude this information. If the bubble or chamber was as robust as claimed by Pariser and others, this content would not have reached the individual.

> From multiple sources I've read that limited ownership is leading to consolidation.

You are referring to ownership structures. “Fragmentation of national mediaspheres” here refers to the audience, specifically the concern that the increasing number of media offers, especially with the advent of the internet, would fragment the national audience and have adverse effects on discourse and democracy.

> That might be true, but it's not proof that FB or EC don't exist.

It is not epistemologically possible to prove that these effects do not exist. There is limited evidence that they exist in specific contexts, but barely any evidence for a population-wide effect.
The page's title was a bit click-baity (Scientists have discovered a new physical paradox):
The opening paragraph is:

>Researchers from the Peter the Great St.Petersburg Polytechnic University (SPbPU) have discovered and theoretically explained a new physical effect: amplitude of mechanical vibrations can grow without external influence
I wonder why systemd-nspawn isn't mentioned/used more. I've been using it for years for full system containerization and I'm really happy with how lightweight and functional it is.

> I don't know what the word is (linked?) but their currency is interchangeable. You can go to a Singapore bank with $100 BND and get $100 SGD (no fee) and vice versa.

I believe the term is "pegged"[1], although what you describe sounds like it is much more involved.

While I agree that classroom teaching has advantages, and am not trying to argue the points from the article... online learning is not limited to just what happens on video calls. That would be like saying that daily standup meetings are not the best environment to code in. Of course not. That isn't the point. They are about giving new information and coordinating, then letting go off to do their work. Online learning is the same - give info, coordinate, then students go off and do their work. It cannot be compared directly to 6 hours in a classroom because they are fundamentally different methods of working. They both have pros and cons.
Huawei blocked: Tech must be stripped from UK's 5G network by 2027
piracy is taking someone else's work without compensating them for that work. There are lots of forms of work that require nothing but time. Programming is one, lawyer work, accounting work, digital design work, planning, managing. I'm sure we could list 100s more.

I don't know what the legal term is for hiring someone for a service and then not paying them for that service.

My first search came up with "theft of services"

https://en.wikipedia.org/wiki/Theft_of_services

If you want the your tax forms filled out you pay the tax accountant. If you want the movie you pay the creators of the movie.

I know there is a difference in the the movie already exits but is that an important difference? When I arrive at the tax accountant's office to collect my tax forms they already exist. Maybe I should just make a copy for free and leave and say "copies are free so it's not theft"?

It's not the document that was stolen, it was the value of their time.
- The robot is in your house the whole 168 hours a week, not just 4. You're assuming a good cleaning robot would be absolutely useless for anything else, like cooking, laundry, etc.

- 4-year robot lifetime is overly pessimistic. If upgrade is not the reason (which has nothing to do with lifetime, it's your choice to upgrade), a robot could last way more than 4-years (especially with right-to-repair laws in place).

- That said, such a robot will most likely be available for less than $21k and very soon in the near future.
I turn into a zombie when nearly asleep. You can help me stand up, order me to do things and I will obey with no memories of it happening. If you order me to go to another room (e.g. the bedroom, as my girlfriend does), I will be very confused next morning.
>All else fails, toss them in the trash as I leave the store

That Joe is a BIG Asshole move.
Quality is a broad concept. Warranties are probably more about durability and cost of replacement. Two manufacturers giving the same period of warranty (no matter how long and no matter the number of items they sell) probably expect the same failure rate or service costs as % of their margin. The functionality can be much different though.
I've long held the thought of having a mailbox that receives [everything]@[domain], except certain blacklisted addresses.

As certain addresses get spam and/or I lose interest in the business I gave the address to, I add them to the blacklist.
So far, I'm using AWS SES, which seems to be focused on the sending of marketing emails, and are not fussed on receiving, but includes rudimentary blacklisting. So far, it's zero cost.
> Except that if the average transaction is say $50 (which seems kinda low) that means your turnover for the day was $100 million.

I don't think that seems low. A grocery store or a bakery probably sees a lot of transaction in the 2$ to 5$ range.

But, to be fair, even at 'only' 4 million $ turnover your point still stands.
It's not line count, it's the dot product of line count and conceptual clarity.

There's a sweet spot where code is as terse as it can be while still being easy to read. The abstractions are clear and fit the domain, they're not decorated with poorly configured edge cases, and they're no more nested than they need to be.

It's debatable if this ideal has ever existed, but it's nice to believe it might be possible.
>gunpowder doesn't explode

Define "explode".

Any chemical reaction that produces more outputs than inputs by volume can explode if you trap that pressure.

The flame front on gunpowder isn't fast enough to make a pressure wave that sounds like a bang if there's nothing to trap the combustion byproducts (like the space behind a bullet as it travels down the barrel).

You can harmlessly set off gunpowder (old school black powder and equivalents) as a party trick. Don't try that with Semtex.

I'm not an acoustics expert but I think it's going to be fundamentally very hard if not impossible to build a shotspotter type system that both works in an urban environment (where sound bounces off all sorts of things) and doesn't get a false positive from things like motorcycles backfiring.
> This is a key difference between US policy & Canadian policy that I have informally noticed while growing up on the border (with family ties on both sides).

My wife's Canadian and I'm American, and we've discussed this point too. My theory is that Canada's parliamentary system generally puts one party in charge of the executive and legislative, so it's easier for that party to get things done. Of course there are times when a party in the US controls both branches and we still struggle to get things done. I would assume that most larger changes happens on this scenarios though.

And of course the US seems to suffer from partisanship in general more than Canada, but I can't back that up.
Transactions on credit/debit cards are not rounded so it's rarely an issue these days when even corner stores are not handling much cash.

Also, the rounding algorithm is in the article you linked to:

> If the price ends in a one, two, six, or seven it gets rounded down to 0 or 5; and rounded up if it ends in three, four, eight or nine.

That tends to work out pretty even for consumer/store if you are buying groups of randomly priced items.
Very interesting. I was thinking of using Json Schema forms to populate [0] models in Django where we have a JsonField. Is it possible?

Traditionally the instructor owns copyright for course material:

“ Few reported cases exist addressing the issue of whether the educational institution or the faculty member owns the copyright to teaching materials prepared by a faculty member. All the reported cases that do exist have either held, or stated in dictum, that the copyright to the materials at issue in those cases belonged to the faculty member, at least in the absence of an explicit agreement to the contrary between the institution and the faculty member. Thus, cases have essentially followed the "teacher exception" to the work for hire rule.”

It is outrage culture. It wasn't a problem for decades and all of a sudden it is.
Yes you are right agreed with you
The administration is clearly following the currently available science and what the global community is doing.
On the other hand the teachers Union in LA wants to use this opportunity to increase federal funding and get a moratorium on charter schools. If that isn't political I don't know what is. I heard them say they didn't have time for preparations? What have they been doing for almost 5 month?

Both, NY and LA, the big school districts that won't open this fall, are in deep blue states and not swing States. They hope to signal a strategy to the rest of the country. We will see how that's gonna work out.

> Metrication process in US is really way too slow.

I've thought that too, but wonder about what metrification would mean for things like screw thread pitch (which is measured in TPI, and I assume would change if the units changed).
Super sad! It was due to Grant, Adam, and Jamie that I fancied making things from an early age. I used to do LEGO versions of their builds as a kid that helped me a lot to become a designer and engineer today. The kind of multi-disciplinary notion of life they professed was a key for me to approach my education.
I still remember dubbed versions of their show in Hindi on Discovery and my parents allowing to watch it beyond TV as "Whatever is on discovery is good for kids"

I resonated a lot with Grant as he was very simple and introvert-ish among the whole lot.

This year is like a nightmare.

RIP Grant :'(
This is an odd opinion piece to have made it to HN front page. It's essentially a collection of unsubstantiated claims that would likely have no impact to policy even if they were demonstrably true because the driving factor is human safety and not efficacy or ease of teaching.

Remote teaching may be harder, require more work, and have pitfalls that are quickly overcome in person. Much more useful would be a collection of ways to mitigate them, rather than an airing of grievances.

Maybe I'm being too hard on this, and it's just a good serving up of the real conversation. So, what are other folks doing to overcome the difficulties outlined in the article?

Reading the room, avoiding distraction, using humor, and inability to establish command.

On the last note, I will say that I believe it's a red herring. The most soft spoken person, who clearly has a passion to share their subject, will be easily gifted this by a willing audience. Even over Zoom.
Color barcode becomes ISO standard
If you don’t want to use the term “piracy”, the best alternative I’ve heard is “bootlegging”. Credit for the idea goes to the author of https://daringfireball.net/, who suggested that term way back in 2009.
This looks really cool. I put in some numbers for a service that I am considering, and the answer was the opposite of what I was intuitively expecting, which proves the need for something like this.

Some feedback:

- s/(one person)/(per person)/g
- The "cover costs" section doesn't really make sense to me. For example, in one example, the breakdown says that I will burn $10000 extra, but that I will also cover costs with 23 hours of use. How does it know how much use it will take to cover costs? How does it know how much profit is generated per hour of use? Am I misunderstanding something?
- It would be nice if the formula used was displayed in small text or in a tooltip or something.
"astral projection" has no basis in objective reality
I personally don’t but there’s a DIY robocars event near me where people compete in races using little self driving cars. Some people were using the AWS one but more popular in the “stock” division was the Donkeycar -

I haven’t made one, I just go with my kids to show them how cool it is to be an engineer, but Donkeycar seems popular and performs well in the contests.

Interestingly, I've noticed that in certain parts of the Amazon website these prices are rounded up for display. Maybe the price jumps out more when given in this format, since it breaks the pattern? I also notice that multibuy deals in supermarkets are invariably multiples of 50p (e.g. 2 for £3).

Makes you wonder how much of this stuff is calculated decision making and how much is just dogma.
The worst are wireless chargers on the bedside table. Too dim, and you can't tell they're charging in the daytime. Too bright, and they're obnoxious at night. And the lights are actually needed because the chargers are so finicky to position, so you can't just slap a piece of electrical tape over them, which is my usual solution to LEDs. I suppose manufacturers could have the brightness level adapt with an ambient light sensor, but then the price goes up. Ugh.

My personal least favorite LED ever, however, was a temporary apartment I lived in that put a wifi router with a blinking blue LED directly over the bed. WHY?!

> While podman can run systemd inside a container, it isn’t widely adopted in the images in docker hub and elsewhere.

With podman and rootfs it's also normal to run a full systemd inside a container and you don't need special considerations from OCI images for rootfs to work just fine.

> There is probably just fedora supporting this.

RHEL is behind podman and I will take RHEL support over Canonical every day.

Podman is also available on most major distros and easy to port to new ones without requiring someone to use some proprietary crapware solution like snappy.
That is the default, but it depends what your employment contract says. The relationship between a university and its academic staff is not quite a typical employer/employee relationship: academics have much more freedom to choose what to work on, and typically have more ownership of intellectual property they produce.

Sometimes yes, just like in real life. Not always through.

What is complicity through, is to favoring trolls speech. Telling troll victim to shut up or to tell him that what is happening to him is because he was not sufficiently silent.

Sometimes, trolling is crazies. Other times, and quite often, it is tactic to shut up opponents. And it works and used to work. People who ignored trolls are not to be heard, because trolling stopped their speech.

And yet other times, what you call troll is someone espousing genuine opinion, but it is too comfortable and politically beneficial to pretend it does not exists.
I put power strips with switches on most electronic stuff to make sure they are switched completely off when I don't need them. Gets rid of the annoying lights as well.

I especially like those with foot switches on a separate cord. The power strip on all the power adapters can remain hidden, but you can still easily switch everything on and off.
Do it. In NZ, we got rid of everything below $0.10 and pretty much no one cares.

I'm old enough to remember halfpenny coins here in the UK. I've got a few someplace that I kept.

When they were withdrawn in 1984, they were worth more than 1.5p in today's money. The country survived, so I dare say we could safely discontinue 1p (and 2p) coins.

I live here in Ontario, and you're right the sky did not fall. The rounding isn't a big deal really, even on scale. It rounds to the nearest nickel, which is or is not in favour of the consumer/business. For example, $2.07 rounds to $2.05, while $2.08 rounds to $2.10. This should net out to an immaterial benefit to either side. It also is only rounded when paying cash. Card transactions are not rounded.

FYI Sales tax is 13% in Ontario now
Multiple layers of electrical tape on most of my devices to bring the lights down to a reasonable level. A brand name battery charger and an off-brand HDMI splitter are the worst things I own for intensely bright blue LEDs.
