Some additional context from TFA, which is actually pretty insightful.

> One preliminary explanation from the New Jersey study was that the emergency licensed teachers were working in schools that had a record of helping students make strong academic gains. It’s possible that the schools had supports in place, such as teacher coaching, a strong curriculum or something else that compensated for less training... Another recent study, out of Oakland, California, backs up this theory.

> There’s some evidence that teacher licensure tests are mildly accurate predictors of who will be a good educator. All else equal, a school would be better off selecting candidates with a higher test score, especially if they’re going to be teaching math or science. But that general rule would mischaracterize a lot of teachers — some test well but don’t have great classroom management or interpersonal skills, while others may not test well but are effective at working with children.

I'm not an expert, but my impression of modern classrooms is that teachers don't have as much leeway to choose what or how they teach, compared to, say 50 years ago. They have a strictly defined curriculum to get through, and they're generally spending a lot of their classroom hours teaching to standardized tests. Might the difference in "classroom management" skill, which is evidently untested in teacher licensing, be the most significant thing left that can make one teacher better than another? That is, if we make teachers (essentially) read from the same script, maybe it's all in the delivery?

And if this is untested in teacher licensing, maybe it's somewhat evenly distributed between licensed and unlicensed teachers?
You have to be extremely careful and conscious about what you are able to upload and what you are not.

E-mails are generally OK as long as they are not containing customer info (most aren't). The moment you get a data file from the customer (e.g. a CAD drawing, spreadsheet, some analysis, etc.) that is protected by a restrictive NDA, you must not even upload it to the corporate Onedrive to provide it to a colleague. It has to go through an on-premises server - or you have to send someone with an (encrypted) USB stick. And access is strictly controlled, only people who need it will have it.

This stuff is taken extremely seriously - a security breach leaking customer data because someone carelessly uploaded a confidential file where they shouldn't have could cost you millions in both lost customers and huge lawsuits.

>If clauses in contracts are enough to keep you out of legal trouble the same should be true independently of the size of the provider.

The problem is that you are not only after the clause in the contract to "keep you out of legal trouble" and suing the provider for money should anything go wrong. You actually want to be 99.9999% sure that nothing bad happens in the first place, that you have almost 100% uptime and the data are safe, not only to legally cover your backside.

Why? Because your own customers (or government) would haul your arse to court otherwise. No amount of compensation you get out of the service provider will fix it should it come to that. You could easily go bankrupt or to prison here.

Small startups have no chance to compete in this area with giants like Microsoft or Amazon. E.g. we are in the EU and are legally forbidden from storing some data in US hosted servers. So both Microsoft and Amazon (and also Google) have complied and have EU datacenters for this reason - and you can explicitly specify (both technically and contractually) which instances your e-mail or files are allowed to be stored in and which ones not.

An US startup with no own infrastructure only renting servers/compute from e.g. Amazon? How exactly are they going to ensure this, regardless of what is in the contract with me when I have no influence on how they structure their own contracts with their cloud providers?

Esp. when that company is here today but may not be tomorrow - goes bust, gets bought out by a competitor, etc. No amount of legalese will protect you here when you have nobody left to sue.

Unfortunately in this area the deck is stacked against startups and small companies sky-high, even if you aren't trying to convince them to give you all their confidential data and only trying to sell much more pedestrian services - e.g. payment services or something like payroll management.
We buy them at Costco, which is the cheapest I've found.
Oh I'm 100% for archiving and keeping the music around forever, even if the artist wants it gone honestly.
I still pirate TV and movies, and that is to the best of my knowledge legal in my district. I sometimes pirate console video games, but pretty much never do if they're available on steam.

Piracy is a service problem, not a financial problem. I also do use patreon for some creators I enjoy.
> Any accidental policy that disincentivizes R&D is stupid

The problem with section 174 is not that it disincentivizes R&D. These rules were already in place for R&D spending, and were generally welcomed by companies with actual R&D expenditures.

The problem with section 174 is that it essentially forces ALL expenditure on software development to be treated like R&D.
The idea that Western readers can clearly see the draconian overtones of tyranny seems laughable after the last several years. And let's not even mention the fact that Marxism, fascism and Nazism have all originated in Europe...
As much as I hate to defend Ubisoft on basically anything... Yeah reading that article it's very clear he's discussing this in the context of their subscription service. It's no crazier than someone wouldn't own their games through acquired via Ubisoft subscription than movies via Netflix or music via Spotify.

Is the trend of non-ownership a good thing? I don't think so. And yet I also begrudgingly admit that I listen to a much wider variety of music via streaming than was ever available in my cd/mp3 collection...
As someone not in the market this sounds awful. Is this really true?
Even if it was buying, piracy would be misappropriation at best.

How long have you been using Spotify?

It seems to me that at every opportunity, the team responsible for Spotify has made it worse. The UI is made significantly worse every major update. The only good thing I can think of that they’ve added over the past decade or so has been dark mode and I am not exaggerating. Have you seen the state of playlists and sorting/filtering options? You know, one of the most important things about music software?

Literally the only reason I’m using (and paying for) Spotify now is that there isn’t a legitimate competitor to switch to. Spotify is not worthy of respect of loyalty and it’s certainly not deserving of not being pirated from.
How do you "absolutely" know? It seems trivial to hide a death for a long period of time without a potentially extensive investigation.

"They moved abroad."
> FWIW, they start counting function arguments from 0, so _2 is indeed the velocity.

Dammit yes, you’re right! Well, it’s not a bit less confusing.

The most frustrating is that they have a point: we need to be stricter about disambiguating functions and numbers, and derivation really should be an operator.

But you don’t need to go all the way to zero-indexing (which is definitely not a thing in the fields I know) or positional arguments. This is putting abstract notation purity above practical concerns. It’s not surprising they like Scheme.
Wear out HOW much faster, are we talking 1% faster? 10% faster... etc.

The difference between replacing a wearable component at 100,000 km or 101,000 doesn't make a huge difference (ignoring the fact that it could just fail earlier due to one of a hundred different environmental reasons)
For me it's surprising. Based on the regular discussions I read on here, I assume that most are accomplished and confident.
A mobile app for this would be awesome, even if a browser control
It's really not that bad. CrunchyRoll has _almost_ everything, especially since Sony bought Funimation and AOD shut down. Some of the real Blockbusters miss sometimes (Oshi no ko, Cyberpunk, Pluto, etc.) because those are the ones that are worth it for Netflix, Amazon and Disney+. CR is great for someone watching a lot of anime. If you want to watch the one or two big shows each season you might not find them there though. I rarely find anything I can't watch in Japanese with english subtitles.

(Old stuff is often missing too. if you're after that those I understand what you mean.)
For humans, being able to teach is an innate capability. After all, we've been able to teach our children for 100,000 years before schools existed.

Today, parents routinely teach their kids things like reading and arithmetic.

The best teachers I had were professors at university, and they never had a day of teacher training. They simply knew the subject material.

What skills a masters degree in education confers is a mystery to me.
It's not biased to report "car brand X becomes useless because of temps, unlike all other cars"

That is indeed a story, and should caution those in certain environments not to buy that brand. It also shows a lack of testing, to sell cars into a market, where they won't work reliably for part of the year.

And a completely different tact, a car breaking down is expected. An entire production model being flawed, and defective, is not.

This is not even slightly biased.
What happens when COVID 25 hits and they lock us down again “for our own safety”? Any license plate captured and the owner gets a knock on the door from the police. Like China.
I stopped pirating for a decade and started again when platforms became so fragmented and inconvenient that torrenting is the more convenient option again. On the other hand I buy a lot of records, both old and new, so I'm objectively spending more on music than I've ever been.
MUBI is the only content subscription I still happily keep.

Why analyze when you can whitelist?
The quality ceiling for any recording you have is the quality ceiling of the weakest link in your audio pipeline.

This means, to be able to get a good sound from any system, you have to feed it a good signal, and that path starts with recording.

Current audio codecs are great from a psychoacoustic point of view. A good encoder can create an enjoyable file at modest bitrates (192kbps for MP3, and 128kbps for AAC IIRC), and retain most of the details.

The audible residue when you subtract a MP3 from a FLAC is not details per se, but instrument separation and perceived size of the sound stage. People generally call this snake oil, but I have the same amplifier for the last 30 years, and I can say how different qualities of audio render through the same pipeline. A good recording stored losslessly can bring the concert to your home, up to a point. MP3 re-encodings of the same record will sound flatter and smaller.

Lastly, it's not possible to completely contain the sound of a symphony orchestra in a stereo recording. That's not happening. So there's always a limit.

>People like to complain about the lack of ownership rights, but the convenience is what really matters

Yes, and ownership provides many conveniences that limited and revocable licenses do not.
All my life, it has been common parlance among every person I have ever spoken with to refer to a depleted battery as a "dead" battery.

When someone announced that their cell battery is dead, I have never once in my life heard someone ask for clarification on whether the battery was incapable of charging or is simply depleted. I have also never once heard a correction of the person with the depleted battery when they announce that they have charged their phone.

I have also heard these same speech patterns pertaining to vehicles. It is odd to demand that a written work that is authored for popular consumption not to use the popular parlance.
Doesn't Russia still have TOR nodes running ? Are those blocked ?
Indeed. Spotify is convenient but the audio files are locked and cannot be easily copied to another devices.

Buying the CD/audio files don't pose that issue.
IMO, notes are anything that's worth writing down.

I have cheatsheets full of Excel formulas for complex transformations. Without it, I'd be forced to look up the ad-ridden website I originally pulled it from, on a work computer that doesn't have an adblocker.

Same goes for stuff I do rarely enough that I need to look up instructions each time. For example, I don't deploy websites except for personal use, so I usually need to re-read Digital Ocean docs to set up my stack on a Linux VM, assign SFTP users etc. Those articles are extremely long and full of related page links. Once I have my core setup steps down, I can just put those into my note.

Besides that, I have notes with images for clothes shopping. Instead of wasting time browsing in-store, I can quickly see whether they have any of the 10-12 types of clothing I usually buy (tops, bottoms, shoes, 4 subcategories for each).

Yes, the Cybertruck lacks these standard features as cost-saving measures
The term blacklist comes from the term black book, which originated in the 1400s as a reference to "a list of people who had committed crimes or fallen out of favor with leaders".

It is called that because King Henry VIII used a literal black book. Not everything is about skin color. Not everything is about American racial dynamics. Stop projecting your issues on everything.
Singaporean here. What would you say is the point?

My own tldr is that we severely lacked in a number of areas:land mass, natural resources, a defensible position, a meaningful economy.

Geography was pretty much the only thing we had going for us. That and amazing leadership.
I'm a pasty nerd but I'm related to landscapers... if you need a truck, the cybertruck isn't a truck.
It's just gotten to the point where I optimize for laziness. When I'm at home I watch on the streaming apps for the most part, because it's easy.

When I'm traveling, I download tv shows I think I want to watch and stick it in VLC on my iPad. The exception being movies from the apple TV app. I have had no problems renting and downloading the video through that.

Maybe they fixed it, but ever since I downloaded a bunch in the HBO app only to find it would NOT play once I was in the air, I just gotta do what I gotta do to be able to actually watch in flight.

Oh man, and the other thing apps will do, is if you're not careful, they'll download some awful low res version of the show by default. ugh.
put boiling water in a jar and then shake it up? Ouch! when you agitate hot water, it evaporates a lot faster, bringing the pressure in the jar to great heights. If your seal is not good, or if you open the jar scalding water can come shooting out onto your hands.

a similar thing happens when you put boiling water in a blender and turn the blender on (your blender seal is not good) explosive results.
Agreed. I have bought many many things on Apple iTunes store, and I have an archive of MP3s that I've collected that I don't want to lose, and I also pay for Spotify because it's the most convenient service for listening to music and it'll probably the be last one I cancel before I move into a cardboard box.
> using these proprietary services on Linux or Raspberry Pi etc is not possibile

I can't speak to Raspberry Pi (and other non-x86 boards), but on my PC I can listen to Spotify just fine. I don't even have to use Chrome. It works as well on Firefox.
What a whopper of a combo of incompetence and malfeasance! Any sanely competent s/w dev team would have totally easily come up with a scheme to encrypt the videos and upload them to vehicle / owner authenticated areas of some cloud bucket somewhere with audit logging and the employees could have had their activities monitored and audited - looks like it is no one's interest at Tesla to give a crap about their customers.
did you try warth's left-recursion hack for packrat parsers? i'm curious what your experience was with it if so
Agreed. Clearly they're using some kind of fuzzy text matching, which isn't quite working correctly. They need to bring back keyword-based matching. At least provide an option to enable that.
> If there was a way to configure my players to fingerprint the content and send money to the artist as I play it

There isn't.

I fail to see how piracy helps artists today.
Here here. All of this I think is slowly blowing up the Toffler-esque fantasy that many people in the "information worker" class tier had, that the "information age" was unique in creating a set of workers and industries immune to the ugliness and exploitation of industrial capitalism.

For periods of time we've been paid well to do craftsman-like work, without (on the whole) industrial automation and intense labour discipline.

Capitalism finds a way to route around that kind of blockage. And this is what Sundar and Musk and crew are up to now. And why there's such intense investment in "AI."
Not separate at all. You are right that he did weep.
This is such an American take. A lot of people are not American and your issues are not ours. Stop the Cultural Imperialism. Educate yourself about the rest of the world.
I've been researching this for another issue. Anyhow, expensing R&D is a perennial political issue. Logically, if you're creating an income-producing asset, then you have to depreciate it over its useful life. The theory is sound, but of course politicians can mess with it, as they do.

But I thought the "useful life" of software was 3 years. No?
How would you do regenerative braking train couplers between engines and battery cars? (That at present have just an air hose to hold brakes open per Westinghouse, but no power wiring or data cabling or a spec yet)

Would standard EV charger specs work for coupling battery train cars to engines and/or regenerative braking cars?

Maybe at least 1 Gbps and PoE+ to support a mesh network for sensors?

Presumably hyperloop teams have solutions for this?
What does your personal ethics say about paying somebody to build a system that prohibits certain kinds of people from receiving certain kinds of information? Even if a trickle of that money makes it to the artist, doesn't that seems like a technology that's ripe for abuse?
I don’t mind steam, but it’s not like you really “own” your library even on that platform. So it has probably been a while since most of us actually owned a video game the way it was 30 years ago.

Sure, the subscription services are taking it even further, but as long as you’re not in total control of the stuff you own, it’s not really yours. At least in my opinion.
So for you it's normal backup and restore a system in an unknown state?

I hope you do not manage any important system, your own personal desktop included IF it's important for you...

That sounds excellent, hopefully it's hard for Apple to maintain both set ups and just go global, like they did for their chargers.
I've had one experience with Ubisoft in the last decade. Their demo works on my switch, but the paid game can't log into their cloud and is unplayable (my ISP uses a CGNAT, and the IP address was banned).

Of course, I bought it from the Nintendo Store, which means no refund (a charge back would get me banned from the Nintendo Store, nuking unrelated purchases).

They've definitely trained me to not buy their games. I'm strongly considering setting up a Switch emulator so I can play the title in question.
This is the answer. People buy a product that's known to surveil them, then get upset when it's misused.

Of course it's misused, there are humans involved.
> to the point where I may just buy a different car.

I love this line of rhetoric. Seriously, I doubt that you will. If you consider all of the shenanigans that Tesla is known to do, you shouldn't have bought the car if you're concerned about privacy. Any car that has cameras on the car that looks at the interior of the car should not have been purchased in the first place. OF COURSE they will be looking at video when they shouldn't be. Has there ever been an example of a company that hasn't? Ring has done it. Roomba has done it. Open it to any data not just camera, and people like Uber have used that data for nefarious purposes.

Any device that sends back data to the home office is just too ripe for misuse. Then, when it comes out in examples like this that it has occured, there is 0 liability for the company involved. Maybe the company makes an example out of the employees in various ways up to dismissal, but the company just shrugs it off.
I'm in that camp and can suggest a few recommendations in order of:

https://d3dcoder.net/ -- The DX12 book is the latest edition. The books have several chapters at the beginning covering 3d transformations.

https://foundationsofgameenginedev.com/ -- The first installation, Mathematics. This will cover a lot more ground and derive things from first principles while not being overly formal.

https://www.mathfor3dgameprogramming.com/ -- A lot more formal than most game/graphics math books, and goes into more depth, particularly on the linear algebra.

I’m surprised it’s open to begin with.

Their recommendation component is one of the few reasons I pay. Everything I ever wanted to hear is on YouTube.
Wouldn't you just expect this type of self serving behaviour though?

It seems like people would be far more likely to discuss this and expose it once they left the company and their job wasn't on the line than when they worked for the company.
If it’s a choice between safety and privacy, I will always choose privacy. Because without it, you are not safe.
I think it's mostly orthogonal. Pirating music only takes money away from artists in the case that you were going to buy their music, and don't now because you downloaded a file, which is probably the vast minority of downloads, I would guess.

On the other hand, there are a ton of ways to support artists if you have the means, whether it's attending shows, buying merch, or what have you, none of which can be properly "pirated" in this sense.
I'm not sure it's worth it even for most IO bound applications. The first couple of IO bound examples that come to mind (an app doing bulk disk or network IO, eg sequential file access or bulk data transfer) would logically seem to work just as well without async since the bottleneck is the disk or network card or connection.

I'd guess it could be an advantage for high concurrency applications that are CPU bound, but could be made IO bound by optimizing the userspace code. But OS threads are pretty efficient and you can have zillions of them, so the async upside is quite bounded, so this niche would seem smallish.
Infrastructure funding floats new hope for Great Lakes shipping
There have been multiple stories about EVs getting stuck in snow then running out of battery and being towed.

But the particular cases where the car itself has broken down seem to be limited to Teslas.

Even in the heavily moderated Tesla Club Sweden forum people have started questioning the reliability of these cars in the winter.
