skysight-inc/HackerNews huggingface dataset:
It’s a different system, but it seems interesting to compare with what Google does for code review suggestions [1].

> The final model was calibrated for a target precision of 50%. That is, we tuned the model and the suggestions filtering, so that 50% of suggested edits on our evaluation dataset are correct. In general, increasing the target precision reduces the number of shown suggested edits, and decreasing the target precision leads to more incorrect suggested edits. Incorrect suggested edits take the developers time and reduce the developers’ trust in the feature. We found that a target precision of 50% provides a good balance.

Also, it seems like if the suggestions are too good then they’ll be blindly trusted and if they’re too bad they’ll be ignored?

Where to set the balance likely depends on the UI. For a web search, how many results do you click on?

It's difficult to admit you've been tricked. I took a look at your post history and it's obvious I'm not going to be swaying you any time soon lol.
All my tech podcasts (and now print media apparently) have been pushing a "self-driving cars are almost here" narrative for the last couple weeks. But to be blunt here, isn't this total bullshit? Let's say that's 5 years away; well that's at best in the realm of "who knows". Has anyone here made an accurate 5 year roadmap? Yeah....

I don't know what exactly is going on here, maybe Waymo and Cruise media relations teams are really earning their bonuses this year, but it's pretty gross. Kevin Roose had the guy from Cruise on and they were talking about the effect of self driving cars on gig drivers, and he said he felt like Cruise needed to take an active part in helping those drivers retrain or find other work. All I wanted was a single follow up: "what are you currently working on in that space?" Because the answer would be "lol we're not actually working on it, and if anyone does it it will be the government" (which is also the AI industry's response).

But also these cars are driving in the best of circumstances: nice weather, slow or predictable traffic, reasonable road layouts, etc. Wake me up when a car can drive me through snow on a highway narrowed to a single lane on New Year's Eve after I've been drinking heavily.

My guess here is that industry is hoping we'll start adapting to self-driving cars, not the other way around. I'm not saying that's bad, but it's an entirely different story than "The tech is close to working!" It would be more like "The tech never worked right, we basically made trams, and that was fine, but woof very expensive"

Not to take away from the rest of it, but there is a very new process for L2-3 certification in Europe. As far as I know, only Mercedes has completed it and released a product (with TUV Rheinland), but TUV Sud is also offering homologation services for European type certification. The L4+ process for Europe is still in working group, with standards expected to be released next year (and 2025 for the UK).

Manufacturers are all pursuing self-certification in the US because regulators have been unwilling to answer petitions either way or commit to firm guidelines.
I don't think he's moving to AI. It's a whole lot harder to mass scam people in AI than in crypto. BTC and ETH are still pretty high in price. He's still only covering crypto. But he's right that many scammers, grifters, opportunists have moved to AI.

Even the ones left in crypto are basically trying to associate their crypto projects with AI as much as possible.

If real estate was hot, crypto would try to associate with real estate. If room temperature superconductors are invented, they'd say crypto for superconductors. Basically, in order for useless crypto shitcoins to get attention, they attach themselves to anything that's hot.

Depends upon your son but perhaps youtube + forum engagement with others centred about math channels that have lower+upper school and university material.

> It follows that we must not introduce any topic for which we cannot first convince the students that they should want to pursue it.

There are several good math related youtube channels and they have the advantage of allowing viewers to find questions | topics that they find of interest and then pursue .. which can lead to following for the latest releases and discussing with others that comment.

Matt is very engaging and there's a fair bit of back and forth from others on his channel comments which might take your son down a path of greater engagement and exploration.

Most of the LA wells were tapped out long ago. None of them are gushing oil.
Also I think the biggest discovery is that the “brain” part of the human “eyes plus brain” part is extremely hard, and “sensor which can see depth” probably makes the brain part easier.

That said, Tesla was never in a position to use LiDAR because it has generally been extremely expensive. Solid state lidars are supposedly now hitting low volume testing for 2025 production years. Tesla is a mass manufacturer not a self driving start up, so there was never really an option for them to offer LiDAR without an extremely expensive self driving package.

One thing however that was obviously wrong was Elon’s promises, which were extremely misleading and helped build his fortune thanks to the misunderstanding. (Assuming this inflated stock values)

With solid state LiDAR supposedly becoming available for $500 in the next two years (a promise we have heard since 2016 but one that seems possibly to finally be coming true) we may never end up seeing if Tesla could have ever done it with pure vision - they could go with solid state LiDAR for forward facing driving in the next few years.

That said, over promising is going well for them. Perhaps they will just keep doing that.

I really feel like your first paragraph refutes your second. Nuclear is a lot of things, but cheap is not one of them. Possibly because nuclear production is forced to account for externalities while fossil fuels aren’t, but it’s not cheap.

The general rule of the thumb in crypto is that everything will get exploited. Its a matter of “when”, not “if”.

I wouldn’t even trust Metamask in the long run. If the wallet doesn’t get exploited, something that interacts with the wallet will.

If crypto ever becomes a bigger market, you’ll eventually have state actors trying to exploit protocols and wallets, and they’ll be more sophisticated than the North Korean hackers.

We are making the same mistake now with chatGPT. We think if it progressed so much in the last 3 years, future progress will go at the same speed. But the last 1% is exponentially harder than the previous 99%.

Potential Metallic Orb Design
Yesterday's article (https://news.ycombinator.com/item?id=36170105) on flying metallic orbs caught my eye, so I decided to ask ChatGPT how this could be designed. It came up with a design that seems plausible to me (a non-expert), essentially using gyroscopes to induce controllable spin, and uses the Magnus effect to allow the orb to bend through the air like a soccer ball. Wanted to get Hacker New's take on whether this design is possible.

Structure and Composition: The orb's structure is a sphere composed of strong, lightweight materials akin to those used in modern aircraft or spacecraft. These materials are capable of withstanding the pressures and forces experienced during flight while also minimizing the orb's overall weight.

Buoyancy: The orb is filled with a lighter-than-air gas such as helium or hydrogen, which provides the necessary lift. This is a similar concept to what's used in airships or weather balloons. The buoyancy offsets the weight of the orb and its internal components, rendering it effectively weightless at sea level.

Control Moment Gyroscope (CMG): The orb houses a device known as a Control Moment Gyroscope. A CMG consists of a high-speed spinning wheel (or rotor) mounted on a gimbal, which permits the rotation of the wheel to be oriented in different directions. The CMG acts as the 'engine' for the orb, enabling it to spin, and subsequently, move through the air. This function is grounded in the principle of conservation of angular momentum. A change in the orientation of the spinning CMG rotor produces a torque, which induces the orb to spin in the opposite direction. By expertly controlling the CMG's spin, we can precisely manipulate the rotation of the orb.

Magnus Effect: The principal means of locomotion of the orb relies on the Magnus effect. This is a phenomenon that generates a force on a rotating body moving through a fluid medium (like air), perpendicular to the direction of motion. It's the same principle that allows a baseball to curve when thrown with spin or a soccer ball to swerve mid-flight. As the orb rotates, it creates lift in the direction of the spin, propelling the orb sideways. By adjusting the rotation of the orb using the CMG, we can modify the direction of the lift, hence controlling the movement of the orb.

Guidance System: A sophisticated computer system serves as the orb's 'brain.' This system collects data from onboard sensors, calculates the necessary CMG alterations to modify the orb's rotation as needed, and makes real-time adjustments, enabling detailed and responsive maneuvering of the orb.

Power Supply: An energy-dense battery provides power to both the CMG and the onboard computer system. The battery is designed for extended use, ensuring that the orb can remain operational for long durations.

Who chooses who to bear the negative externalities. Seems like if you're the one who's drilling, you should not be immune to the consequences of the pollution. But again, the ones least well positioned to deal with the pollution are the ones who have to suffer it.

In my opinion, whether or not any signal is "in a language" is not a physical fact, but a matter of definition.

Banks are required to be FDIC insured because we want a place to exist where risk-averse people can store their money. So then they can go to a bank, put it in a CD and have an assurance that if the bank goes bust, they don't lose their savings.

The drawback of this system is that it's expensive. If you want to open a bank account, they're going to have some requirements, like having your paycheck direct deposited into it, or minimum deposit requirements etc. Or they'll charge you a fee. Somehow they have to make back that cost.

PayPal isn't a savings account. Its primary purpose is transferring money to other people. In normal use there should never be so much in the account that it should need to be insured. And not paying the regulatory overhead to be a bank is how they avoid the requirements banks impose to have an account.

There is no reason we can't have both. If you're risk-averse and you want an insured institution to hold your savings, you go to a bank. If you want to open an account just to transfer money, you go to a non-bank payment processor.

But now you're proposing to prohibit the latter thing and make everyone pay more for something even when they don't need it, instead of letting people choose when they do.

It's things like this that keep accumulating which cause the cost of living to go up faster than wages.
Herbicides are generally absorbed into plants and can't be washed off. This is a non-selective herbicide, so it usually wouldn't intentionally be used on produce, since it would kill the crop. However, sometimes herbicides are used right before harvest as a desiccant to kill and dry crops in the field. You probably wouldn't use this herbicide for that though. It is true that someone working with the pesticide is a lot more likely to get exposed.

Again, certification (a matter of judgement) is a much lower standard than verification (a matter of truth). There is a lot of literature on the difference between the two words, and I assumed you chose to use the word verification intentionally. If that wasn’t the case, then it is better to choose certification when you mean that rather than verification in the future.

> My brother in Christ

disingenuous start, this will be interesting...

> why should I put in the time and effort to learn an auxiliary tool to my job?

if you think git (or version control) is auxiliary tool then you have not worked on real software. I'm not saying this is you, but IF it's you (or anyone else reading): Writing side scripts and minor modifications on an existing project is not building real software, it's hobby coding, which is fine but you don't get to act like a software engineer. You're as much an engineer as someone cooking a random meal once a week is a chef.

> I learned Z80 assembly when I was 12 years old. Prolog when I was 15. When git came ... it was an absolute impenetrable brick wall and let me emphasize

Did you consider maybe that your "learning" of z80 asm or prolog was not complete? or possibly faux, false, fake, or gasp you're might not be as smart as you think? Or that when you were a kid you had way more time on your hands than now? The possibilities are infinite for an explanation (that is if what you're saying is true). "OMG Git is hard" is not one of the first 100 reasons that come to mind.

> It was not until Charles Duan's git tutorial that I felt I am comfortable with it

That's a good tutorial, but you never get comfortable with Git (or any other technical subject matter imho) until you work with it, and it will take practice and -sorry to say- humbleness in that you (or anyone else) can have hard time understanding something that many others find simple. It doesn't automatically mean it's a hard subject because you find it hard.

Git is _not_ anymore hard that any other abstraction. You work hard you learn, you don't you won't.

Keep a Movin' Dan on Gamma Brainwaves
Prompt: Can you tell me about gamma brain waves but do so in the style of "Keep a movin' Dan" from Cory Doctorow's Down and Out int he Magic Kingdom?

Well now, partner, you sure picked a fine topic to chat about, them gamma brain waves. They're like the wild stallions of the cerebral plains, hard to corral and even harder to truly understand. But, you asked, and Keep a Movin' Dan is a man of his word.

See, gamma brain waves are like the quickest critters in the neural desert, scurrying around at around 25 to 100 Hz. Some brain scientists even say they can clock 'em goin' as high as 200 Hz! It's a fast-paced rodeo inside your head, if you can imagine that.

These gamma waves, they're associated with conscious awareness, with being right in the thick of things. They're a part of higher thought processes, ya know? When you're solving a complex puzzle or piecing together memories, gamma waves are the cowboys wrangling up the thoughts to make sense out of 'em.

But that ain't all. There's a notion going 'round in the brain science saloon that gamma waves could be part of a much grander event. Some folks think they help to synchronize the activity of different brain regions. It's like having a grand round-up of neural information, so everything falls into line and the brain works as a team, unified.

Now, I reckon there's still a lot we don't know about gamma brain waves. They're elusive, like a coyote in the moonlight. But the brain scientists are always on their trail, hunting for new insights and understanding. Just remember, partner, the brain's a wild frontier, and the exploration's never truly done.

Well now, I hope that painted a bit of a picture for ya. Remember, the mind's a vast prairie, and it's up to you to ride it well. Just like old Keep a Movin' Dan, always on the journey, always headed for that horizon.
I can relate to that.

I used to keep white mice and rats as a kid and I noticed repeatedly that when the population rose above a critical level the animals' behavior would change. The most notable change was that they would stop and or slow their breeding. What shocked me most was that mothers would actually kill their babies by biting them—usually on their bellies.
The ones I used are sufficiently fast. Each one usually comes with a data sheet that have performance specifications. Some sacrifice speed and capacity for data integrity (writing twice), but in general, the main features and use-cases are highlighted on the first page.
