" these are not very common activities in industrialized societies"

Of course they are.

They're just regular jobs.

If you live near the ocean, there are people who fish, if you live inland, there are people who farm - and the myriad of various related activities. And a million mundane things in between. And no, they're definitely not the 'providence of college kids'.

Having grown up around 'house builders', no, I don't really think there's that much philosophical insight in that activity either, but for those who don't have any of those skill and want to try it out, I'm sure it would be an interesting exercise.
Yes, and as a general rule when cases are brought they are under the auspices of a federal civil rights violation. These are very difficult cases to prosecute though, so I think the FBI overfocuses on lower hanging fruit unless there's a political motivation from the top to drive this.
Hm, these are high-level concepts so it's hard.

Duality in mathematics is in general a principle that objects in one category can be mapped onto another category (and vice versa), that two objects are reflections of each other in some abstract sense.

https://en.wikipedia.org/wiki/Duality_(mathematics)

It most often appears as a principle in geometry. Looking at or working with the 'dual' of something can give additional insight or allow another way of working. For example, Fourier Transform can be considered a type of duality.

I'm not clear what computational techniques are expected here - I personally don't think it's a very well-formed problem.
> That's higher than 5 of the shown previous 10 years

So in other words, it's basically exactly the median of the last 10 years? That seems to reinforce the title's claim.

We run multiple vacation rentals through airbnb and others. AirBNB does not side with the host more often. It prefers to do nothing.

We had drug dealers moving product from one. We told airbnb not to contact the guests. They contact them anyways trying to "resolve" the situation.

Every time guests break rules like smoking that have clearly posted fees, airbnb says they can't help. Even when the guests admit to it.

When we needed to call CPS on morons endangering their one year old, we were not able to get the guests information to give to the police.

Their support will straight up lie to you to resolve cases faster.
Vaccination is not without risk. Sometimes, but rarely, people have bad reactions to vaccines.

The ethical case for vaccinating against rhinoviruses isn't really there, even if it were viable to do so.
my 2 cents: anyone who even thinks of defunding the police should visit a country with no police (for example a favella in Rio at night) and report back their results. The experiment will likely not be very repeatable.
Incidentally, half of those companies you've mentioned are in the top 50 spenders for marketing [1]. I'd hazard to say that they are all in the top 100 in global spend.

Does this really need AI? Couldn't you just take the maximum of the fourier transform of the rendering multiplied with the audio? Maybe across multiple dimensions.
The title is editorialized and ought to be changed. He's referring to "fake news", not to the internet broadly.

It still puts a sinking feeling in my stomach. In-fact, maybe even moreso. I can't believe how much and how fast things have changed in 12 years.
I developed that tweak for Python 2.7 and I am running in production with Python 3.6. I tested with later Python versions, too.

Do you have some pointers about arenas always using mmap? I'd like to know how that trick can work if that was the case.
The problem is, it's not just Apple, the entire software industry has taken a turn for the worse. Everything has automatic updates these days: my phone, my watch, my computer, my TV, my car, and every single app I use on these platforms, and they are constantly breaking stuff, undoing functionality, loosing data and occasionally ruining devices permanently. I've been on the other side of these things too, with panicked-laden all night coding sessions trying to fix a bad update that went out. I've been in the software industry for almost 25 years now, I'm not sure what the answer is but the direction things have gone is unacceptable.
How the hell does Tesla (sales: ~400,000) have a bigger market cap than GM (sales: ~2,000,000)? Is this just the market being irrational and Musk being a good salesman?

Is there any reason to think mainstream automakers can't put batteries in their cars? Is there any reason to believe Tesla's self-driving aspirations will pay off (over say, GM Cruise, or Waymo)?

I'm sure Tesla is fine and they make a few nice luxury cars, but I feel like I'm going crazy here: How is Tesla worth $380B, but Porsche is worth only 20B?
I think the parent is suggesting akin to a Tyranny of the Majority with a locally elected police.

For example, if I live in a small town that where 80% of the people intent their C code with tabs and I use spaces, they could theoretically elect a police chief who espouses tabs-jingoism and treats spaces-programmers less fairly.

What is the difference in testing for covid at the beginning compared to now? I seems that no one takes into account that the world wide deaths are down as infections spike, and that the two week latency doesn't seem to be a factor.
U.S. upgrades safety probe into nearly 159,000 Tesla vehicles
To be fair they funded that by dropping a ton of spend out of the marketing (which makes sense).

I know there were layoffs so I'm sure they were in full cost-cutting mode by the time the pandemic hit full swing
> Do the math sometime on what kind of bandwidth and storage capacity a large agency like NYPD

40,000 officers (rounded up)

8 hours of full HD video can be stored in 10 gigs of storage

do this 365 days a year for every officer

S3 standard costs less than 3 cents per gigabyte to store per month

result: about 50 million dollars to store 8 hours of FHD video of every officer every day for a year

The NYPD anual budget is 5 billion dollars. Thus, storing all this video would cost about 1% of the budget. I've made generous roundings in favor of overestimating this cost, and in reality it would be much less.

This 'new' WebP format is not radically different, but just pushes the same use-cases further
(The web. Not archival. Not camera capture.), sticking to simplicity and usefulness.

10 years is a long time since WebP-v1, and techno has evolved since. We can go much lower in bitrate for still-good-enough quality, and that's what we're interested in exploring.

AVIF was designed starting from a video codec, similar to WebP-v1 in the early stages, and this has some drawbacks (that later we needed to correct in WebP, that was confusing).
WebP2 is aiming at images-on-the-web right away, and not as an afterthought.

You don't hire security personnel to address previous breaches.
> "once counterparties have authenticated each other's messages" is the omission that changes the meaning of the quote.

No, it doesn't. The dispute isn't about the need for counterparties to authenticate each other. Yes, we all agree that it's good if email receivers can validate the authenticity of the sender. That's not at dispute. The question is, is it good if third parties also have the ability to authenticate the sender of an email at a later point in time (using DKIM specifically). tptacek claimed that there is no legitimate need for such a thing, and I provided a counter-example to that.
Same story repeating over and over again.

Initial hype. Then abuse and overuse. Disillusionment. Decline. At some point people will finally figure out what OOP is all about by looking up decades' old works and youtube videos (if youtube is still available) and hopefully will learn to integrate it.

A discussion with a dev recently when I started refactoring his PR with him and started pulling business logic from services into model.

Dev: "NOOO!!! You can't do this!!!"

Me: "But why?"

"You can't put code in model. Model is for fields and getters and setters only and business logic belongs in business services"

Me: "Why?"

Dev: blank stare... (imagined, this was over zoom)

Me: "So... why do you bother with having fields private if you plan to have public getters and setters for everything?"

Dev: blank stare

Me: "Isn't object oriented programming about having logic alongside the data rather than separate? Isn't it about modeling operations that act on the data to limit exposure to internal state?"

Dev: blank stare

Me: sigh...
Ironic coming from the guy who was praised for his campaign's tech savvyness and ability to use the power of the internet and social media to win.

I guess he's right. Many people did believe his victory was a threat to the country. /joke

I'm looking very forward to a Biden presidency, just to see how far people will flip-flop and bend their beliefs to justify whatever he does as president, now that the victory is secured and he no longer has to campaign. In the end, politics is very much like sports ball. People will accept anything as long as "their guy" is doing it.
Your sentence makes very little sense to me because the seroconversion has a high chance of causing life-altering side effects. I'd say it would be irresponsible to suggest that to the general public.

This is true. Engagement -> Ad Views -> $$$

If they down-weighted negative engagement they could easily solve this though. There are pretty trivial content analysis tools that spit out a hostility score for a corpus of text.

Facebook just doesn't care to do this.
Head Fakes. Learning spikes under the guise of competition are amazing tools. Hackathon's, etc. Competition internally with this cut-throat attitude (because so much money, potentially, is on the line) is toxic and can create some serious mental health issues. This isn't a discussion of competition in the markets, free market and all, it's about competition with the people you work with day in and day out. It can create animosity and anxiety at work. I would much rather work with a genius who's humble than an asshole who is just looking for the next promotion.

To truly grow as a company you need to grow as teams. Cooperation, trust, empathy for your customers as well as your coworkers. Positions of leadership should be given to those who show an aptitude to lead through problems to desirable outcomes, regardless of who/where they are. Flatter org structures to prevent this chasm of salary difference which creates this toxicity in competition for those spots.

Netflix pays their engineers a ton, because they provide the value. Everyone is compensated at a level that everyone is happy working there (for the most part, happiness is relative, I digress). Companies should be providing everything they can to those who provide value to the company. If an individual wants more responsibility, they must provide more value as a result.
Your tools suggest to me you are European. ;-)

I swore off MDF in my shop a long time ago though. I know it paints well but I just can't abide by the dust it makes. Baltic Birch plywood has become the lowest of woods that I will now use — preferring a multi-ply Europly for the nicer projects.

It costs a fortune but as I have moved up to better woods I find I cannot go back to Big Box construction lumber or, you know, MDF or similar.
He has almost certainly sold stock already. $110k rounds to zero compared to even just this RSU grant. The salary is symbolic
Why is it that the same people who think the solution to bad public schools is more oversight and accountability, seem to oppose increased oversight and accountability for bad police departments?

There's no indication that funding is an actual problem that a lot of these "bad" departments face. Teachers regularly have to buy their own supplies for their classrooms. Have you ever heard of a cop needing pay out of their own pocket for ammo for their service weapon, gas for their patrol car, or batteries for their radios?
With Pulsar you have to run (as I understand it) not only ZooKeeper, but also Apache BookKeeper. Operationally, Pulsar sounds even more complex than Kafka.

I've never managed any of these, but I know that both ZK and Kafka have a reputation for being operationally complex. I've read comments by other people on HN about Pulsar being complex, too.

I'm optimistic about Pulsar becoming a widely deployed tool once they can get rid of the ZK dependency. In particular since Pulsar seems quite friendly to non-Java languages, while BK requires Java on the client and does not, and will not ever, support other languages.
As an Australian I've had a terrible time finding a decent cup of coffee in Europe (Italy excepted, but even then the standards aren't great).

I admit I haven't been to Budapest or Bratislava but I've been to some of the supposedly-best places in Berlin and been pretty disappointed. A shocking fraction of them use UHT milk.
wow so finally they pulled this through during covid, good timing with the vaccines just coming out.

Any airbnb=er here wants to invest in a travel company? lol you never know..
At least the executive summary is mostly about how Tesla's products are bad and their financials are bad. The market disagrees on both counts.
Newspapers, too - see "yellow journalism" a century or more ago. Ultimately, it all comes back to the printing press. The ability to spread information has always been a threat to the powers that be.

Oh, wait, Obama said "democracy", not "powers that be". Well... I will admit that I am concerned that on the internet, the feedback loops are too tight, so that hot takes crowd out reasonable thought. That's a formula for gut reactions, which isn't great for democracy. But the parent has a point, too, that this is said about every medium at some point.

I fear that Obama is right. I also fear that this is the usual "threatening the powers that be/the existing order" complaint, and that any proposed solution will be worse than the problem. Not sure where that leaves me...
> If you're concerned about writing potentially sensitive video to non-volatile storage, that can be solved via technical means. Just encrypt the video with an ephemeral key kept in memory, then store the encrypted video on non-volatile storage. You get best of both worlds.

Once you've recorded that video it's subject to FOIA requests and rules of evidence and all kinds of things like that. If your recording only includes the past minute or 2, you can be reasonably sure it doesn't include something it shouldn't (such as a victim who asked not to be recorded from an hour ago). If hitting that button commits a 5 hour buffer, then you're going to have all kinds of stuff now "in the public record" that maybe shouldn't be there. But also you now have 5 hours of more or less useless video that you have to store and account for (which costs $).

> Mind showing your calculations? Keep in mind you don't have to store the videos in perpetuity. Limiting it to 180 days (with option to extend if the incident is being disputed) would suffice for most cases.

It's actually less about the storage and more about the bandwidth to transfer that data to the storage location. Though the cost of the storage itself can still be an issue even if you're only retaining it for 90-180 days.

There's a whole bunch of factors of course, but pick a reasonable bit rate (5-10 Mbps perhaps) for your recording and multiply it by the number of hours recorded per officer and the number of officers in an agency. Chicago PD has 12,000 police officers. I don't know how many of them work on a given day but let's say 10,000. Say each one records 5 hours per day based on the 5 hour buffer proposed here.

10,000 * 5 hours = 50,000 hours of footage per day

50,000 hours * 5 Mbps = 112.5 terabytes per day

112.5 terabytes uploaded in 24 hours = 10.4 Gbps

(you need to be able to upload a full day's recording within 24 hours or you'll never catch up)

Doing this quickly so hopefully my math isn't off but it's in line with what I remember. 10Gbps being uploaded 24/7 to the cloud. 20 petabytes stored at any moment if you're holding everything for 180 days.

Sure, you can attack some of these numbers (not every officer will have a recordable interaction every day etc.) but I hope it gets the point across.
The first example I can think of, because I run into it often, is when you use syncopation. It's made even worse if the syncopated line contains chords, and then even more-so if the note lengths within the chord are not robotically static.

Writing that on the MIDI piano roll is slobber proof. But if you take music written that way and view it as sheet music, it is nearly impossible to read because of the many ties that don't even necessarily begin or even end in the same place as the others.

It all ends up looking like layered sheets of snow sliding off your roof. A ribbon of differently-sagging tie-lines making it not only unsightly, but impossible to read.

Why sheet music if you have MIDI already? Because as someone who records, I use MIDI for writing, but I don't expect other musicians to follow my piano rolls when recording guitar, bass, vocals, etc. and I wouldn't want them ever to sound as robotic as MIDI tends to be.

Drums however - that's one area where MIDI piano roll to sheet music actually works flawlessly, even if the notes don't have the usual x| appearance.
>HN's perspective on lockdowns might be skewed by the fact that most of us here live in places that actually did have a good faith reasonable response to COVID, but it didn't really work in the absence of a coordinated nationwide response.

...care to expand on this hypothesis? I've heard variations on a theme around this. I live in an area which seems to have close to 100% mask compliance for the last several months as near as I can tell, and we still have cases increasing. I guess I'm having a hard time believing that it is visitors from Texas (or where ever) coming in and spreading coronavirus. What it seems to indicate to me, is that public shopping, etc. isn't a driver behind the spread.
Maybe Sony is still salling it but was coming out 4/5 years ago without updates. I don’t know who want to buy it instead an A7
Sorry Barack, but I think you mean: “Advertising models on the internet are the biggest threat to our democracy”

The internet, if anything has promoted democratic practice around the world, which is why China wants to shut it out. It has done more for knowledge sharing than any medium in history.

Unfortunately, advertising is one of the the only model big enough to sustain the purchase of massive amounts of hardware which grow the internet, that and movie subscriptions.

But it will die as a model in the next decade I’m sure. When the AI overlords take over, there will be no need for money.
Best show ever :)
There has been malware that pretends to be a HID driver and function as a keylogger and/or execute arbitrary code. While Apple may be being overly cautious here, it's not entirely unreasonable.
The seesaw in revenue over the last 3 quarters is insane: 841M, 334M, 1.3B in Q1, Q2, Q3. They even posted a profit last quarter. I've gotta say, the S1 looks appealing considering how few profitable silicon valley companies there are these days. On the other hand, I have a hard time interpreting whether this is truly a profitable company since the numbers are all over the place.

It also looks like Q3 tends to be their best quarter by far. Is that because of summer vacations?
Ex-NSA, like Google. They do everything to keep your data safe. And do everything to keep the profiling they do based on your data (= their data) safe.

Links to this kind of low quality, evidence-free junk is not worthy of Hacker News. All the claims made are just beyond absurd and desperate in their ridiculousness. This is exactly what you'd expect from a company that is demolishing the net worth of many short sellers.
If you want your coffee to taste like oatmeal, yes.
I disagree strongly on this point. Building up a two-sided marketplace is incredibly difficult. On the consumer side, consider that many younger travelers have zero affinity towards hotel chains, and manage their entire accommodations arrangement through AirBnB, which feeds into an absolute requirement for hosts to list on the platform. This is not simply two markets you can copy: the feedback loops are so powerful already.
Hypothetically, all footage from an officer, when they're on-shift, could be of interest. And it's probably fair to say that state / the public have a right to that information for some purposes.

In the interest of sanity, I think we can suspend recording for personal moments:
- Bathroom
- Medical
- Break time (e.g. eating)

We can potentially switch to a lower-resolution / audio-only take for the vast majority of a shift. E.g. idling in a cruiser.

As someone else highlighted, what we absolutely want to record is:
- Use of weapon (holster switch)
- Conflict (volume trigger?)
- Immediately preceding interval before camera turned off (presumably, will contain a request / rationale to disable)

Effectively, what we want to do is switch from a trigger-on to a trigger-off. Cops shouldn't have to even think about cameras. They should just work.
What's wrong with cDc?

Is not it like with Apple that most (all?) of Tesla sales are 100k cars while GM has to compromise and sell a lot of cheap vehicles?
I wound up at Caltech by pure luck, finding an institute particularly well suited to my personality and what I needed. For one example, Caltech has an honor system where the default is for the professors and students to be collaborators and trust each other rather than be adversaries.

Thanks, Caltech!
You’re right on you final points. My two rebuttals for advocating for less privacy online is that being online naturally makes you less private, not more.

Previously if someone, government or otherwise, wanted to learn about you, they would need to physically follow you, tap your phones, intercept your post etc. Warrants for searches were built around this.

Online, you can dig into the private life of someone on the other side of the plant who you’ve never met. With the application of computers you can dig into the lives of hundreds of people you’ve never met. All without leaving the comfort of your desk.

The opportunity for fishing expedition is unprecedented at the moment, and it always easy to justify a fishing expedition if you pick a horrific enough crime (child pornography seems to be the favourite right now).

Finally privacy is the strongest bulwark we have against government overreach. That doesn’t mean some top down conspiracy of a totalitarian-elect government. It can be normal everyday government administrators who decide to step outside their bounds for personal reasons, or belief of moral superiority.

Simply put, there’s no better deterrent for bad behaviour than hard work. Privacy makes bad actors work hard for their lunch. It makes the good actors work hard as well, but the solution to that isn’t less privacy, it’s more funding and resources for good actors.
