Tech has infinite possibility in educating people, and may eventually remove the need for school altogether. What has to be faced is:

1) that our theories about education are bad, and that we've been cargo culting traditional education and haven't made any significant changes in the process for hundreds of years,

2) our theories about how to handle the future of education with the new tools that we now have were doomed to failure because of that, and

3) with no theoretical foundation, charlatans tried to push a theory that sheer proximity to technology would have an emergent magical effect on education (while another set of charlatans push a theory that technology has a magical dampening effect on education.)

It's the same situation we're in with governance, or law. The English accidentally and clumsily developed a Parliament that worked, and the people who wiped the King's ass developed into a cabinet. It was productive. We then formalized it by examining what had been done and simply writing it down and sometimes streamlining it. We also do that explicitly in the common law, where we assume that every judicial decision ever made was correct, and concentrate on when they contradict each other to make changes. It's productive, but it's not theory; they're descriptions of history.

Covid was a test for Edtech, and it failed horribly. We need to ground education in reality: we're trying to force unwilling children to remember things. We need to focus on their wills, and their memories, and to come up with theory. We can experiment on adults, although the difference between adult education and children's education is that adults are self-motivated, so this would concentrate on memory methods. When focused on children, how can we give a child the discipline to feel like they want to participate in and contribute to the world? Does that have to do more with social services, the safety net, and giving children real responsibility earlier than with educational theory?

Recent interesting read for me was a failure and partial success trying to use spaced repetition in the classroom. His partial answer was that it was better when everyone shared the same screen and answered together, you move slower than you wish you could, and you don't demand that they remember forever. Also, from my reading, the expected schedule of schooling completely disrupted what he was trying to do. Schools have to be redone, not tweaked. People knew this in the 19th and early 20th century, even if they didn't manage to come up with a formula that worked.

No doubt that there have been poor teaching experiences, but I would counter that my experience with EdTech teachers has been amazing and empowering. Really don't think we can tar all the teachers with the "EdTech sucks" brush.

Do you think there is no value in picking pilots that make the correct split second decisions or screening out pilots that don't?

The priority here is combat effectiveness, not job security for pilots.

On top of all this, they found that he didn't follow the correct procedures that did exist!
I’m not sure about computing hardware, but Waymo absolutely has better sensors, yes.

But it isn’t obvious to me that better sensors outperform better data.

LPIPS and similar don't work if the scene is different, as happens if the random seed doesn't match. This is why they can use it to compare the quantised network, but not against networks with reduced numbers of weights.
I'm pretty sure in the Bay Area most larger tech companies cargo-culted offering employees free fruit (and sometimes vegetables / crudite) -- the argument being that having employees eat these instead of bagged chips/candy would reduce your health care spend in the long run.
It biases results towards people that "studied how to do the test" rather than studying the material that is evaluated.
Nice launch - congrats!
They even think they can exert rights over used album sales. As one example, pretty much all recordings that have rights attributed to an artist named Al Reed, who died in 1990, are blocked for sale on Discogs. Not just his own recordings, pretty much anything he has writing credit for. https://www.discogs.com/artist/623314-Al-Reed

Found this out when I was adding Johnny Winter / Guitar Slinger to the collection and noticed it was blocked for sale. https://www.discogs.com/release/3318469-Johnny-Winter-Guitar...
They're right that the compositor is gamescope, it's made by Valve and it has game-related features, but the person 3 comment-levels above me did seem to be conflating gamescope with the Big Picture UI. You can absolutely use gamescope and not use Big Picture mode at all, lots of people using Wayland do so by wrapping their games in a call to gamescope.
They’re called magnet links.

Depends on the location. I don't like driving in SF especially but there are some areas of Boston that are pretty crazy if you're not used to them and don't intuitively know when to get over into some lane and aren't used to driving pretty aggressively at times.

As I've said, merely predictive models do not quantify over the features of reality.

A weakly inductive model is simply this: the next case will be some average of the prior cases because we assume unknown aspects of the environment will ensure it is so.

An explanatory model tells you why. It says: there are planets, gravity, molecules, mountains, germs, atoms, and so on.

The semantics of explanations are causal properties of reality, and their relationship.

Explanations do not have "parameters" to "minimise". The universal law of gravitation is not a curve fit to data. There was never a dataset of F,M,m,r; netwon did not fit any parameters -- there are no such parameters.
Hey everyone, I created a TypeScript schema validation library
So most TypeScript/JavaScript schema-validation libraries have all kinds of fancy functions for validating everything you could think of under the sun (objects as well as primitives). Problem for me was I already had all kinds of functions for validating things (regexes for strings, checking if something was a boolean or number etc). The only thing that was making me use a schema validation library was trying to validate object properties. I wanted a library that could enable me to use all my existing validator-functions to validate object properties, so I created jet-schema:

LINK: https://github.com/seanpmaxwell/jet-schema

With jet-schema, you setup an object schema like you would other validation libraries, but then you can just pass your existing validator-functions directly to each object property. Jet-schema has features to allow you to set default values and custom error messages for whenever a schema validation fails.
I'm the living example of this. I'm an engineer who thought he's signing up to be the TL to design the architecture and implement the hard parts, and at some point I realized I'm doing a terrible job because in reality I'm just EM-ing this project 90% of the time, while my manager is busy with something else.

I've learned the lesson the hard way.
I think it's more like, "don't do this" because there is perfectly saner alternatives available.
Yes and no. Propaganda is an interesting word. In the US it's tended to imply totalitarian style messaging, but in other parts of the world can apply to advertising as well. I quite like the neutral sense of the word, in which it's simply understood to be something that all organizations - governments, corporations, etc. engage in and you'll do well just to not be suckered in by it.

That said, propaganda isn't necessarily deceptive, but can simply be strong rhetoric.

There is a lot people can do to limit their footprint with respect to mass surveillance, and much of it is in the article. There are now more concrete reasons average people in the USA might need to worry about that, such as helping someone from a restrictive state get an abortion.
The plan is to build a modern PC and the fact that people have to adjust their hardware decisions in such a way (downgrading/using older components) to accommodate linux kind of reiterates my point IMO. If I was installing windows this wouldn’t remotely be a consideration. Though I certainly don’t want windows, it is a notable difference.

> the vast amount of training data they are collecting

They keep pushing this point. And they do appear to be collecting an absolute firehose of data from the millions of vehicles they have on the road. By comparison, Waymo collects a lot less data from many fewer vehicles.

Which leads to some tough questions about Tesla's tech. If they have (conservatively) 10x the training data that Waymo has, why can't their product perform as well as Waymo? Do they need 100x? 1,000x? 10,000x?

Assuming they were at parity with Waymo today, this would suggest that their AI is only at best 10% as effective as Waymo's, and possibly more like 1% or 0.1% or whatever. But since they can't achieve parity, it's not even possible to bound it.

It's entirely possible that their current stack cannot solve the problem of autonomous driving any more than the expert systems of the 60s could do speech translation.

I haven't heard a compelling argument as to why a system that is at best 10% as effective would ever be expected to be the leader.

We use high-precision calculations up to 28 decimal digits that cannot be provided by numeric types available in Javascript. That’s why we do our calculations on the backend.

The OP/EFF says it's a Senate committee that's about to vote on "The Patent Eligibility Restoration Act (PERA), S. 2140."

I don't know tons about the government, but you linked a House bill that looks like it's still in a House committee, and I don't think a Senate committee would be talking about something like that.

Edit: I found this: https://www.judiciary.senate.gov/committee-activity/hearings...

It's an agenda for a Judiciary Committee meeting on Thursday that lists "S. 2140, Patent Eligibility Restoration Act (Tillis, Coons)."
Waymo followed the rest of the alphabet companies in the back to office drama post-covid. You can still get remote positions if they want you badly enough to grant an exception. Cruise did remote, but they're not the best choice lately. Zoox thinks remote work is a sin of the highest order because they're owned by Amazon.
Sorry to burst your bubble but modern FPGAs are already designed this way (latches paired with muxes and LUTs across the lattice). Take a look at the specs for a Xilinx Spartan variant. You still need the routing bits because clock skew and propagation delay are real problems in large circuits.
Gas is cheaper. 2.67 in the remote midwest is the best I've seen last week. Raw fuel shouldn't be an upward driver.

FWIW, Waymo has more cameras than a Tesla. Both companies are removing sensors over time. In some ways removing sensors is easier to prove out with real-life data than adding them. I think it is going to be fascinating to see how it plays out.

It sounds like you're advocating for a world where ordinary people need to choose between:

- not knowing the weather this weekend

- knowing the weather and signing away their firstborn child in the T&C

- becoming an amateur lawyer and spending dozens of hours reading and comparing T&Cs between apps to choose which one to use (until they change the T&Cs again of course, which they'll do without notifying you)

Isn't Waymo operating an autonomous taxi service for 100k trips per week an object example of outperformance?

Additionally, this being simplest I wasn't expecting a new page for every category of unit and the added load time with that.
Indeed. The crazy thing is that so many people still don't understand this.

For the last few years I leave my phone's GPS perma-off unless I'm actively navigating. Of course, I also have my location permissions for apps defaulted off and locked down (except for the two apps I grant conditional access to). I realize that cell tower tracking exists and is used by my mobile provider instead but at least it's a little less accurate. As a side benefit, my battery life is much better.

I've also adopted the healthy lifestyle choice of not using any social media apps on my mobile device (which is surprisingly wonderful once you make the leap). I mostly just use my phone to make and receive calls and texts (and as a remote for my home automation).
> There is really very, very little you can do to avoid government surveillance, and in the end it's almost entirely pointless.

I disagree. It's true that, if you are a person of interest of any reasonably powerful government, there isn't much you can do at all.

However, the sort of surveillance most people should be concerned about is an automated one. It isn't really possible for a government to track all their citizens and flag everything, no matter what tech they use. You want to make it difficult for tooling to figure out information about you (no matter what it is) and force government to actually invest resources if they want to figure out something about you, specifically.

When it comes to the US, a lot of information is stored at the state level. That is a lack of centralization that can be exploited.

> tracking device in your pocket that you feed all of your personal information to, data brokers

Not all of them do. If you are concerned about that, some are more privacy oriented than others. 'Dumb' phones still exist - although their use probably makes you stand out already.
I think I'd be willing to accept software patents if the patent was required to include complete source code. Basically, if it acted as delayed open source.

Ostensibly the patent system exists to incentivize open publishing of new technologies, but it isn't worth squat if full of vague language written by lawyers.
It’s interesting to see how this research emphasizes the continued need for human expertise, even in the era of advanced AI. It highlights that while AI can significantly boost productivity, the value of human judgment and domain knowledge remains crucial.
Waymo has much better data than Tesla. It is just the coverage of that data that is different.

> I think the SAT is a ludicrous setup given that most people never see anything like it in their lives again

Yeah, I guess.

I think the issue is that the folks best suited to get the most out of college don’t really need to prep much to absolutely crush the SAT.

Most people are just woefully underprepared.

> but the practice of studying for passing an exam of some kind is an absolutely invaluable skill

Yep. Learning how to study, learn, and prep for a test are good skills to have.

That said, for folks who have done well in a semi-rigorous school environment and read the right things (high-brow periodicals), very little test prep is actually needed to get them close to their theoretical max score.

There are a few catches, though:

- Some people in the US have an incredibly irrational fear of math.

- The math curriculum is super-slow and limited for those who like math, often turning them away from it (or at least the high school math classes).

- Most folks have no idea what university-level literacy looks like. Doing things like reading “high-brow” periodicals gives high school students most of the vocab and text structures covered in the SAT.
This strikes me as a really strange way to define EdTech:

> In this article, I’m defining EdTech as any student-employed, internet-connected digital device; this includes computers, laptops, tablets, cell phones, and smart watches. I am not discussing or evaluating the use of digital devices by teachers.

Aren't there a huge swath of self-defined "EdTech" startups aimed at tools for teachers, and-or use in the class, perhaps exclusively by the teacher?

You can avoid all 5 almost* entirely and make amazing progress by doing bodyweight exercises at home, 2-3 times a week :) There are plenty of free guides out there where you can start at almost any level. E.g. can't do a pushup? put your knees down. Still can't? Do it at a head-up incline. Still can't? Push against a wall. Keep track and make progress until you can move to the next harder exercise. And always remember it's a marathon, not a sprint, so be patient with yourself.

* Can't make any promises. You might get hurt. You might need to pay for some kind of pull up system. But generally speaking: the sooner you stop looking for the perfect time/situation and just start, the easier it all becomes.
Children model the behavior of their parents. It is very hard to compensate for an unhelpful home environment. I think any effective intervention has to go far beyond simply making resources available.
Of course they would like to avoid replacing every (affected) key they ever sold if they don't absolutely have to. But if they sold cars and this was a defective airbag they would have been forced to replace them.

You as a manufacturer are responsible for the products you bring to market — don't want to recall your products? Then ensure they work and you don't put all your eggs in one basket.

In this case Yubico is very likely not legally bound to recall, but I made a case how this is an issue of trust. You know what would have been a good move? A deal where you can order a new one at strongly reduced prices if you can show you had an affected device, or something among those lines. Or selling the affected ones for cheap and give the customers the choice. There are many ways to deal with that situation in a better way than they did and they decided to choose the one that helped their very short term bottom line the most.

As a owner of an affected Yubikey I have to saybthat the whole episode put an questionmark behind thir product for me. Not because it was affected, because of how they dealt with it.
