so photon electron scattering is a perfectly valid interpretation of

"light scattering from an electric charge"

"

But look up, you misquote Dyson: Dyson didn't write "light scattering from an electric charge" but wrote "light scattering by an electric field" .

You also misread me:

1) a photon can not be converted into two "electrons" and I did not write this (but in the past positrons were called positive electrons).

2) the electron positron pair (from a single photon, internal to the feynman diagram) is only intermediate but as charges are influenced by a strong electric field (say a nucleus), before annihilating back into a single photon.

3) the incoming particles are a photon and a nucleus, and the outcoming particles are again a photon and a nucleus, this is obviously scattering

This is different from Compton scattering (scattering of light from a practically free electron) or its low energy limit Thomson scattering, but in the case of scattering from atoms still high enough energy to eject an electron.

This is different from Coherent Compton scattering, which is scattering of light from an atom, or rather from an electron that remains bound to the atom, such that instead of the compton wavelength of the electron, the compton wavelength of the atom is used:
"Compton found that some X-rays experienced no wavelength shift despite being scattered through large angles; in each of these cases the photon failed to eject an electron.[5] Thus the magnitude of the shift is related not to the Compton wavelength of the electron, but to the Compton wavelength of the entire atom, which can be upwards of 10000 times smaller. This is known as "coherent" scattering off the entire atom since the atom remains intact, gaining no internal excitation." (From Wikipedia page on Compton scattering)

I still interpret Dyson's "light scattering from an electric field" as probably referring to the Meitner-Hupfeld effect:

I live in Ireland, in the countryside. The farmers here are mostly livestock so i don't think there's much insecticide use. We used to get hundreds of bugs at kitchen window on summer evenings, the last two or three years there are not as many. Thing is, I've only been in this house a few years. The timescale is too short for it to be meaningful. It could be weather patterns, it could be that they don't get attracted to the LED bulbs as much as the old lighting we had when we moved in. The bird population does not appear to be suffering, they're everywhere you look around here, so there must be bugs to eat.

A website to curate all react tutorials
Hi All, I have been learning React for sometime now, and I must say that there are lots and lots of tutorials, how-tos, videos and more content about React.

I feel that there's a need for a website that curates and organizes all this information about React in one place.

I have had this thought for sometime and would love to build something like this in my spare time. I would love to hear your opinions and suggestion.

> Actually, to be fair, Android may be worse these days, I've had to start turning off all notifications for apps like Facebook

Either I'm some sort of privacy nut, completely boring or my macOS/iOS combo works out well but I simply get so few alerts that I just use my devices less than a couple of years ago.

Both Apple platforms allow you to essentially go into "silence" mode. Android/Windows seem to be built to spam you (hey you can opt out! but we'll reset those options on updates - for you who FOMO).
Absolutely. I used to care when facebook or tinder or whatever app dinged at me (I call out these two specifically just because they're the most recent ones I've disabled). Now, I assume the ding has nothing to do with me and should be ignored (and, then I turn off notifications or uninstall it, once I realize the app is abusing its place on my phone/tablet/computer and not respecting my time and attention).

Facebook had this bug as far as accepting group requests very early on, maybe around 2010. Early enough that groups were limited to your college.

I wrote a script to accept invitations to every group ID from 1 to 10000. It even added me to groups that didn't exist yet, presumably just adding my ID and the group ID to a table. So when someone created a group to rant about me being in all their groups, I was in it and, as the first member, an admin.

Facebook fixed the bug when I reported it and first kicked me out of my legitimate groups, then fixed that too, though they didn't pay bounties then.

Legally I have no idea what the government claims applies or does not, but reading the declaration it seems pretty clear that the founders had the still-radical notion that most/all of these fundamental rights apply to all people ("men", in the text, and "[white] men" in practice). There wasn't even such a thing as "American" when it was written.

If the US thinks the bill of rights should only apply to citizens of the US, the US is morally bankrupt.
There isn't even any reactive current, it's just a non-sinusoidal load current because there is a rectifier and capacitors for smoothing the rectified voltage at the input.
> Why are you even discussing tort law?

As I expressly stated, to demonstrate that two moral principals that contradict claims made upthread are well established in our society: (1) that the particular sensitivity of a victim to harm from a particular wrong doesn't mitigate the wrongdoers responsibility for the harm, and (2) that experiencing adverse emotional states is a harm.
Android has a "Do Not Disturb" mode, and it works well enough, but it is all or nothing. There are notifications I want. I want to know when one of my co-workers needs my involvement, for example, and I want to know when a friend is trying to reach me on facebook messenger. I don't want to know when 13 of my friends are "interested in events in your area", which facebook has decided is worthy of my notifications bar.

So, the apps I don't absolutely need to hear from get disabled completely, even though there are notifications I would welcome from those apps. facebook is perhaps the most annoying because I know they have the ability in-house to get this right. They're choosing not to, and they're choosing to ramp up the user-hostile behavior, because having people constantly engaged with facebook is profitable.
1a) If you're presenting via webex/zoom never share your main screen (either share a 2nd desktop screen or single app).

1b) Try to always present without mirroring your screen. it's harder to follow with high-res, but that's an argument maybe your res is too high.

2) If using Powerpoint, use presentation mode (and preso-mode for energy settings so you don't accidentally go into lockscreen).

Barring the above, I go offline on both Outlook and Slack during presentation mode.

> remember, 2 8k displays does not turn into a 16k display headset, because you need to double the height as well

Do you? I suppose everything that doesn't match the traditional 16:9 aspect ratio we use now is incorrect then? What about the fact that our displays were all 4:3 prior to that?

I guess it depends on whether we are considering 16k and 8k as something denoting specific sets of height and width that are standardized, as we have started to do with 4k (which is usually talking about 3840x2160, to my knowledge, because nobody wants to say 2160p).

The kicker is that the baby boomers also want the younger generation (who can’t afford homes) to pay for their entitlements. It’s like going to dinner with your rich uncle and he stiffs you on the bill. Housing is the biggest problem of this generation. Exorbitant rent seeking sucks up all marginal resources, leading to greater inequality and less of a means to fund entitlements. The irony.

Could a Blockchain/DHT solution work for this? Normalize and hash the data and send it to the network to check its karma. If there's no karma then it's a new customer, otherwise the karma tells if it's a good/bad customer. Then after they buy you add or reduce a karma point.

No, it was extremely good and cool that the EU told corporations to stick to one standard. The market is terrible in making things convenient for consumers if they want to switch phones, as it doesn't make them money.

One thing for sure: they are working on something really big, and have been for some time now. Apple believes in focusing on things that matter, often to the exclusion of everything else. When they get real quiet and only release minimal spec bump upgrades you know something big is coming. That said, there’s no way this will be 16k right off the bat. By third gen, maybe, but not right off the bat.
Is it just me, or are we entering a dark age of computing?
Someone chime in and feel free to correct me if I'm wrong, but here's how I understand the "regulation".

The EU decided that having a single standard port to charge a smartphone was a good idea and in the long run, save a little bit of money and a little bit on electronic waste since people would be able to go to any store and purchase for sale 1 Standard Smartphone Charger™ and 1 Standard Smartphone Cable™.

Then they conferred their preference to the Smartphone Industry™ and said "Okay, you guys sort it out. Pick a standard, incorporate it going forward, or we will bring down the regulatory hammer and not even we want to do that."

At that point USB was proving to be more or less a de facto standard anyway, so the industry said okay, settled on that, and somehow Apple got away with being able to just bundle in an adapter for the Standard Smartphone Cable™. The benefit of this approach rather than the EU swinging the regulatory hammer is it leaves the industry free to update it, say from micro-USB to USB-C, as improvements come along, rather than the EU decreeing that all smartphones use micro-USB which would be Terrible. Thus we have a Standard by Agreement, rather than a Standard by Law and life goes on pretty okay.

For good or for ill, the EU has a massive amount of soft power in their lawmaking alone with repercussions that go beyond the 28 (soon to be 27 again) member states. Any smartphone designer is free to take their phone and go home, but that's a lot of money to leave on the table and its not like anybody particularly liked the old crappy connectors of the past.
Honestly, the control over how everything is show with macOS is a lot better than it is in Windows (imo). Control over where the notifications are, very clear and easy "on/off" for each application (I would prefer the default was off, but no matter), and decent controls over the DnD mode.

The only complaint I have with the Notification settings on macOS is that you have to use a terminal command to alter the length of time a notification is present, which should be a slider in the preference pane as well.

Compared to the current Windows option and Android, it's fairly obnoxious, with notification settings being across different Control Panels (Windows and the Application's own) and the notifications often obscuring parts of the system. Similar to macOS, there isn't a clear way of giving granular control over the time a notification is live (I'm sure it's there, but it's also frustrating this isn't just a slider or a place to enter a value) Too much of the Windows and Android control seems to just be "on/off", with little granularity, and at least with my Android phone, the granularity doesn't seem to work right when you do use it. (Setting up a "Favorites" group of people and adding them to the exceptions for DnD mode doesn't seem to matter for any non-core applications on the phone, even though these applications pull from the same contact list)

The difference for me is just the care and attention on the macOS side of things. Part of me wonders if Apple didn't just watch what Growl did right and then implement it, but regardless some of the design guides are clear: Control over each application, the system's UI space is sacrosanct, respect user privacy in situations where their screen might be exposed, etc.

On Windows, it just seems to be another afterthought to the system.

>This only prevents them from giving outright false summaries. It does not prevent them from casting things in a more favorable light. Only a tiny subset of readers will use the library or archive.org, and they won't be able to say NPR lied.

This is the state of things, huge errors in headline stories are retracted in the following issue with merely a line saying they were wrong. There have been examples of people getting an innocent verdict incorrectly labeled guilty in the story. If transparency is your goal, the story calling them guilty should be reprinted with corrections noted. That would be more transparent, but would not be beneficial to anyone.

>that all retracted stories (even those that defame no one) should be expunged from the online archives.

Again, I do not wish the story expunged from online archives, and it does not appear NPR is doing anything like this. Removing it from their personal archive is a different matter. Leaving it up provides more transparency, but provides no benefit. The error made is clear enough in the retraction, suspicious parties can still see their full error should they want to, and their erroneous story is not causing additional issues by being spread.

This system can absolutely be abused, but as the archive exists it would be easy to tell when it was. Your proposed change allows for a different kind of abuse, also easy to detect, and opens the door for confusion to cause issues. Hell, the only positive you can name is it allows people to easily judge mistakes. Mistakes are inevitable, they need to be judged for their malicious actions, which is still possible in this system.
