I also don't understand why it's necessarily bad...?

Countries face internal security threats. For example, in the UK, the 7/7 bombers were British, ditto the Manchester and London Bridge attacks. In fact most terrorists who attack Britain are British. Are MI5 not meant to spy on Brits?


> "Low-performing students at private schools are having their estimated Cs and Ds bumped up to As"

Do you have an example of this happening? It seems basically impossible from my understanding of the process.

-----

Edit: I think I understand how it can happen. A school with a cohort that is small, but large enough to get the algorithm, and a previously exemplary results, has an unusually bad pupil. I can see this happening in a subject like Further Maths where only good students take it


It's similar to how Bruce Springsteen and The Rolling Stones aren't cool, but still sell out stadiums.

Facebook (the company) will probably settle into a stable pattern like the BBC's radio lineup, where listeners roll from Radio 1, to Radio 2, to Radio 4 as they age.


Wow. What did the training prompts look like?


By this logic, no legislation can ever seek to reduce online child sexual exploitation


I'd prefer we stop all sexual exploitation, not just online and not just of children.

That said, all new legislation must weigh what is lost against what we anticipate to gain.


What similarities do you see between EARN IT and IPA?


Exactly. Vice are trying to frame this like some massive gotcha, but the Navy lays out their strategy openly;

> “While we do not actively recruit on Twitch or through such streaming platforms, the esports team members are there to answer questions about their experiences in the Navy. If a user specifically asks an esports team member about joining the Navy, that team member will move that conversation to a private message to first find out if the interested user is over 17, and if that user is over 17 then the recruiter will thank them for their interest and refer them to Navy.com where they can talk to a recruiter.”

Vice prepends this quote with "In an email to Motherboard, the Navy insisted it wasn’t using Twitch to recruit." which seems like a bizarre mischaracterisation to me


The vast majority of frontline policing is in response to an emergency call, so they have no control over where it is.

HN seems to think police spend their shift waiting for crimes to happen in front of them.


"HN seems to think police spend their shift waiting for crimes to happen in front of them"

Some police stations definitely work that way. And some even close their eyes, so they can go on waiting.

It is in the poorer areas, where you could arrest all day long to the point of why bother. Makes sense, if the source of crime is complicated.


> HN seems to think police spend their shift waiting for crimes to happen in front of them.

No, but when they aren't responding to calls, they spend the rest of their shift going on fishing expeditions.

What do you think traffic cops, for instance, are doing most of their day? What about the cruiser slowly driving through a neighbourhood? They aren't there to respond to a call, they are just running license plates/looking for poorly maintained cars to pull over (Obviously, if someone egregiously breaks traffic rules in front of them, they don't need to look very far - but when nobody's breaking the rules, they can always find someone who looks suspicious.)

The thing is, when you only go on fishing expeditions in poorer neighbourhoods/targeting poorer vehicles, you're going to find that will skew crime statistics - and statistical model based on that will direct even more policing towards those areas.

It's why in the United States, the higher you are on the income ladder, the more illegal drugs you consume - yet the lower you are on the income ladder, the more likely you will end up in prison for drug use.


that's a misdirection. most crimes are not emergencies, and policing encompasses much more than emergency response.

if policing were just, we'd see many more white-collar crimes like corruption, bribery, embezzlement, fraud, extortion, etc. being busted, because those crimes have much larger impact and wider fallout on communities and wider societies.


White collar crime isn't a task for police any more than tax evasion is - those just plain aren't tasks they are meant for as opposed to public safety tasks. Which also explains why they are less funded, even without any conflicts of interest they aren't "sexy" crimes that grab attention, they all also lack urgency and thus are easily "procrastinated". Digging through records can uncover many of them and there are a lot of them.

The police in their current role only show up at the behest of warrants in those situations to search or arrest.


> "they could be worth trillions"

Trillions? 50x the size of Ford? Bigger than, essentially, the current combined value of every car company in the world at the moment?

How?


Ford has $150 billion in debt. 50x the size of Ford would be an enterprise value of $7.5 trillion, even if Ford's share price was $0.


But could images from several telescopes be combined through a Kalman filter or something to resolve higher details?

I am imagining some kind of internet enabled telescope that knows it's GPS location and orientation, and phones home it's imagery to a central server. If millions of people bought and used a product like that, is it theoretically possible to see the lunar rover?


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

TL;DR: for optical wavelengths, with typical image sensors that only detect amplitude and not phase of the electromagnetic wave, you need to do some really hard work to ensure optical coherency. For radio telescopes, it's a lot easier since you measure both amplitude and phase.

Another technique that's a lot easier to accomplish for amateurs is lucky imaging:

In this context, it's relevant to note that the VLT was built with interferometry in mind, and they are now getting it to work reliably. See for instance the page about the GRAVITY instrument: https://www.eso.org/public/teles-instr/paranal-observatory/v...
