I have a new EV9 and the software on it regularly causes near miss accidents. I’m waiting to see accident statistics after it’s been on the market for a while. They’ll be dismal.

Examples: there are pedestrians nearby and the car is in reverse so it wildly swings the acceleration curve around, cycling between “slam on brakes” to “1-2mph” to “why am I on the other side of the street and standing on the break pedal?”

Even without pedestrians it constantly changes the acceleration curve and this cannot be disabled in a way that reliably survives turning the car off and back on.

Once, a motorcycle was lane splitting, so the adaptive cruise control tried to race it and accelerated at the car in front of me. I had to slam on the brakes.

This is by design: There’s a chapter in the manual explaining the dozen different reasons it’ll fail to regen brake at a stoplight (or, from what I can tell, rear end someone on the freeway) because of low visibility. (Including being on a hill, not going straight, pedestrians, vehicles in other lanes, and motorcycles lane splitting.)

Changing from drive to reverse to drive disables one pedal mode. I’m sure that’s caused at least one collision (when you take your foot off the pedals it automatically accelerates, especially in parking lots).

I’ve had it override steering too. Sometimes it tries to force me out of the lane. Sometimes it wants me to stay in the lane so it overrides emergency maneuvers when other cars try to merge into me.

The beeping is constant, and alert fatigue has set in. There’s even an undocumented alert icon that looks like “car is about to explode”. We don’t know what it means.

Even if they fix the safety issues, we plan to sell it for that reason.

Note that all of this idiocy is possible because they wired together the transmission, throttle, brake and vision systems more deeply than “we need emergency override”.

Anyway, mark my words: The accident rates on this model will be high.

Eh, there are better implementations that are less syntactically obtuse (no ->void) but other than that it’s fine. Fairly obvious what it’s supposed to do and I’ve needed similar things in the past. There’s a cppcon talk that use ->* operator for precedence reasons and the macro lets you use it like ‘defer { … };’

> Notice it doesnt have where i want to go listed in its search

I live in an area where OSM is really good with that (just because people contributed the data). If your area is less complete, it feels like it's a good opportunity to contribute!

There are many apps that will help you contribute to the map, or you can do it directly from the website: https://www.openstreetmap.org.

It doesn't mean you need to spend tons of time on it: I contribute data a few times a year. It's better than nothing :-).

Scaling Judge-Time Compute!

I am SUPER EXCITED to publish the 121st episode of the Weaviate Podcast featuring Leonard Tang, Co-Founder of Haize Labs!

Evals are one of the hottest topics out there for people building AI systems. Leonard is absolutely at the cutting edge of this, and I learned so much from our chat!

The podcast covers tons of interesting nuggets around how LLM-as-Judge / Reward Model systems are evolving. Ideas such as UX for Evals, Contrastive Evaluations, Judge Ensembles, Debate Judges, Curating Eval Sets and Adversarial Testing, and of course... Scaling Judge-Time Compute!! --

I highly recommend checking out their new library, `Verdict`, a declarative framework for specifying and executing compound LLM-as-Judge systems.

I hope you find the podcast useful! As always, more than happy to discuss these ideas further with you!

> There's a lot of money in academia for curiously ambitious people just starting their careers so it's an odd thing to say.

No, there isn't. As a new researcher, if your proposal challenges an established line of reasoning from a prominent source, it is overwhelmingly rejected.

> Who explained it to you?

How rude. My opinion is informed by my extensive personal experience and echoed by those in the thread. Who are you to challenge it?

Technically correct, yes, but muonic atoms have a lifetime on the order of microseconds. They aren't really relevant to the everyday-scale physics I was discussing.

There is however Lattice Confinement Fusion [1] which claims to overcome the Coulomb barrier through some kind of "screening" from the electron cloud in the lattice. That seems more like it would work on at everyday scales, though I don't understand it nearly enough to offer any opinion on viability.

talking about focus hacks…when at uni I had odd studying hours, often mixing day and night without any clear distinction.

What kept me grounded were scented candles. IKEA used to sell those with an expected burning time. My favs were the 40hrs ones [0]. My exam preparation was 1 candle for revising notes, 1 candle to go through relevant books and 1-2 candles to do exercises (exp for calculus and similar courses). Add 1 more for the final revision. I was constantly lighting on and off those.

> Just do the right thing and invest in your driving skills.

Well your analogy just proves my point, LOL.

The EU mandates that you take driving school lessons and pass an appropriate examination. Some countries go even further and demand regular medical checkups (Italy does so for senior citizens, if you're 80+ it's once every two years). And if you manage to get in the spotlight for too many or too egregious violations, your license gets suspended to permanently revoked, in addition to some serious fines and the requirement to undergo further evaluation or even therapy (e.g. if you're facing substance addiction issues).

Use that analogy on software/firmware for appliances, and then you get:

- an initial independent certification requirement before introduction into the market - and no, CE doesn't count: all that "CE" signifies is that you as the manufacturer/importer believe your product is conforming to regulations. For many products (IIRC, everything but medical products and devices containing radio transmitters), that's it, you don't even have to go to a third party like the TÜV for a formal audit.

- obligations if you manage to stand out with security issues, including a temporary order to not sell any more units until they are reworked

- getting permanently booted off the market if your violations are too serious.

Agreed, the db migrations are usually the slowest part. Another way to speed this up substantially if you are using postgres and need your test database to be postgres too, is to create and maintain a template database for your tests. This database should have all migrations already run on it and be loaded with whatever general use fixtures you will need. You can then use the Django TEMPLATE setting https://docs.djangoproject.com/en/5.1/ref/settings/#template and Django will clone that database when running your tests.

Most people (statistically) are also broke. The points mean nothing if you’re paying 22% interest on the 3 other cards that you couldn’t even afford to do the balance transfer on. Banks only offer points because they make money on average. By using these products, you are directly benefitting from the financial illiteracy of the most vulnerable parts of our society. I refuse to be part of that system out of principal.

Also, the Visa logo on your debit card applies all of the same benefits as the credit card in regards to risk management. The one time I had my card skimmed, I called the bank, the charges were reversed and they overnighted me a new card.

The steam reactor I guess you might be describing is tokamak, which i agree will be a dead end technology.

There are interesting small fusion reactors that skip the steam step. They compress plasma magnetically, and when the fusion happens, the expanding plasma in turn expands the magnetic field, and the energy is harvested directly from the field. No steam and turbines.

Here is the video where I learned about it: https://www.youtube.com/watch?v=_bDXXWQxK38

Maybe any physicists in this thread could share insight on how feasible this is?

Your main point stands of course: this is a moonshot project, and solar works TODAY!

Its trivial to hire unlicensed folks. Its even more trivial for any insurance company to void warranty case in case of ie electrical fire, flood from work by unlicensed plumbers etc. You do you, not everybody is living in the race-to-the-bottom mode.

Place I live in Europe, it would also be outright illegal. Biggest city or rural, folks here respect their local communities and only get official pros for any serious work.

>Yeah, fan fiction is generally not legal. However, there are some cases where fair use covers it.

Which is a clear failure of the copyright system. Millions of people are expanding our cultural artifacts with their own additions, but all of it is illegal, because they haven't waited another 100 years.

People are interested in these pieces of culture, but they're not going to remain interested in them forever. At least not interested enough to make their own contributions.

Great overview on why Elixir is great for startups. Very much agree with much of what is in here!

I find I am 2x more productive with Elixir vs other langautes just because of all of the things it does behind the scenes.

I'd also add Oban is a game changer as it is a nice plug & play queuing so you don't have to do Redis or rabbitmq

How about just not eat carbs at all and have more consistent & lower blood sugar? (this was an interesting case https://www.youtube.com/watch?v=CG8UU7P8FBU)

I do keto diet long term but for other reasons, often the epilepsy version where it's more strict and higher fat.

>> If no driver accepts the job (as there's a good chance of making a loss), does Uber try offering a higher fare?

Yes, but one of the problems with these gig platforms is that workers do not consider all the costs and end up seeing the top line instead of bottom line. Many people are unaware of hidden costs such as mileage, wear-and-tear, insurance impacts, etc. Further, some gig workers are so desperate for money that the top line is the only thing that matters at the moment, I empathize with this and it hurts me to think so many fellow citizens get into this spot.

I'm also T1D and yep. That's how it goes. Despite having one of the same two breakfasts pretty much every workday for a decade, it's a crapshoot whether I'll be 300 (very high) when I get to work or 50 (very low) or 110 (good). I just have to adjust when I get in to the office. Most days I deal with it fine, but every once in a while I get fed up with it and want to throw something.

> but they're not casually making $2M bonuses like the investment banker types over at Goldman Sachs are

These days, a junior MD in Goldman IB is probably close to 1M USD in total comp (base + bonus). You need to be many years into MD to get paid 2M USD total comp (or have a single, wildly lucky, outlier year). And it takes 20 solid years of outperformance (and soul crushing hours) to get there. The days of "young MDs" in IB divisions is basically over.

This type of business works in the small - when you know your suppliers and your customers. It doesn't work if you have 10,000 customers, or if anyone can email you. For this business it's only a spam problem, though - they have to reject emails from strangers if they get a high volume, exactly the same way they have to reject emails selling Viagra.

That's probably alien to HN and a lot of them may try to contact him, as if they have a possibility of becoming his customer, which they don't.

I see this is fallacy, there are a ton of industrial processes that use a ton of power just to produce heat. A great early use case for fusion will directly use the heat for these industrial processes. For example, aluminum requires ~14-17MWh to produce 1 ton... If you use the heat directly you reduce your processes inefficiency by removing the conversions: heat to steam to electric to heat.

Yeah, next 50 years you might not see coal/nat gas being replaced by fusion. But you will see fusion displacing chunks of what those powerplants will be powering

> With a dense high-energy plasma, you're dealing with a turbulent fluid where any imperfection in your magnetic confinement will likely dmaage the container.

This is true of Tokamak type designs based around continuous confinement, but perhaps less so with something like Helion's design which is based on magnetically firing plasma blobs at each other and achieving fusion through inertial confinement (cf NIF laser-based fusion), with repeated/pulsed operation rather rather than continuous confinement.

No doubt the containment vessel will still suffer damage, but I guess it's a matter of degree - is it still economically viable to operate or not, which I guess needs to be verified experimentally by scaling up and operating for a sufficiently long period of time. Presumably they at least believe the approach is viable or they'd not be pursuing it (and have an agreement in place with Microsoft to power one of their data centers with one of the early units).

Even longer than that, OpenJ9 AOT capabilities, and JIT cache, go back to the Websphere Real-Time JVM, whose branding had nothing to do with J2EE application server.

Most documentation is gone from the Internet, I was able to dig one of the old manuals,

https://ftpmirror.your.org/pub/misc/ftp.software.ibm.com/sof...

These kind of features have been available in commercial JVMs like those for a while now, what the community is finally getting are free beer versions of such capabilities.

There's a very good argument that, after being abolished in 1861, serfdom was re-introduced in the early 1930s via collectivization. Instead of private ownership of serfs, the state effectively owned the peasants who were bound to their collective farms by a system of meagre food-for-labour payments, needing permission to leave the farm/village for any reason, etc. The peasants that "came with" the collective farms were only issued internal passports in the late 1960s. Anyone who knows anything about life in the USSR understands the implications of having no internal passport. You didn't quite need one to breathe when outside your city/town/village, but just about.

Oh?

Then please bear with me and extend the comparison just a tiny bit.

Replace the AI with an advanced species from Mars. Or even better yet an augmented human ... a trans-human if you will.

Both the martian have kids, families, feelings, etc... AND both can absorb the entire internet in , say , a week or two. They are musicians and create new music from their internet experience.

Does their music belong to them?

Do they have to pay rights to all the authors they listened to so far on the internet?

And finally ... what is the difference between my martian and a human today?

> In considering the historic tension between access to education and excellence in education, Hofstadter argued that both anti-intellectualism and utilitarianism were in part consequences of the democratization of knowledge. Moreover, he saw these themes as historically embedded in America's national fabric, resulting from its colonial and evangelical Protestant heritage. He contended that evangelical American Protestantism's anti-intellectual tradition valued the spirit over intellectual rigor.[5]

> Hofstadter described anti-intellectualism as "resentment of the life of the mind, and those who are considered to represent it; and a disposition to constantly minimize the value of that life."[6] He further described the term as a view that "intellectuals...are pretentious, conceited... and snobbish; and very likely immoral, dangerous, and subversive ... The plain sense of the common man is an altogether adequate substitute for, if not actually much superior to, formal knowledge and expertise."[7]

A musician doesn't just pull from their life's experience "of music" to create music. They pull from their entire lived experience, their emotions, the experiences and emotions of their community and world.

An "innocent" AI cannot and does not have any of that. To say all a musician does to create new music is "listen to [existing] music" is reductive and ignores the inherently human expression that is music.

Sure, that's all fine.

What I am saying is that CoMaps seem to believe that Organic-Maps-the-Company is not transparent about what they do with the donations. They have a bunch of other reasons, but this is the one that I can understand.

I can understand that they don't want to donate money to Organic-Maps-the-Company if it then uses it to write proprietary code and later sell it. Not that they necessarily do that, but that's apparently a criticism from the CoMaps dudes.

This is a great comment and comparison.

I think there is a feeling that klarna, and other bnpl companies just lend without checking or caring of consumer credit, or buying power. I've never used them before, so I don't know if this is a case.

With credit cards there is the "appearance" of them checking credit scores, ability to pay , etc.. before giving a credit card.

I say appearance, because as we all know cc companies will just lend cards to anyone, and then charge huge interest rates.

Ultimately it's another form of credit, and it's a minor change on the current system. But since it's finance and lending, it's a step to make lending easier.

In the last instalment of this blog series, we created a rendering pipeline to allow for drawing multiple objects according to their priority, and we also created a GUI anchoring system allowing us to create dynamic and scalable GUI elements.

This time around, I wanted to work on something a bit more interesting: Collisions. Now this took much more time than anticipated. What started as a simple collision detection and resolution system quickly escalated to a full-blown scientific paper comparing five different collision systems. In this blog, I will give an overview of three methods implemented with "pure" ECS as well as share some of the results from the paper I wrote.

Worth noting the distinction between a BDFL-project and a community project.

A community project's aim is loosey-goosey. The mission, values, governance, ownership/control, etc can change. While there is input from the community, they are often led by one or two dominant personalities. The project can often be pressured into making changes that are actually worse, or don't reflect the views of a collective of contributors and users. (I don't personally know of any community projects that are required to do what a majority opinion from the community asks for. In this sense it is more like a typical "democratic" government where a few powerful leaders are really in charge, rather than "the masses")

A BDFL project is, by definition, one person's project. There is no secret agenda, because there's no need for it to be secret. There's no pressure from anyone, the project just does what the leader wants. This means there usually isn't "controversy" because if you don't like it you can lump it.

Organic Maps is, apparently, not a BDFL project. It is a project represented by a corporation with 3 shareholders: Roman (project founder), Viktor, and Alexander (who is not a shareholder but Viktor supposedly holds his share). The concern in this case is that since it's not a BDFL project, the contributors don't know wtf is going to happen when the shareholders disagree and the "majority" decides to sell the company or something. If it were a BDFL project, the owner could still decide to sell it, but in this case, the project founder actually is on the side of the community.

Personally I'm not aware of true BDFL projects working against the aims of its own community, and BDFLs don't really change what they do. The exception is when money is involved. If somebody's just getting paid to write open source, the project is safe; if somebody's selling the project as a Product, beware. "Money is a motive with a universal adaptor on it."

If drivers are supposed to be contractors the pricing should work opposite to the way it does. Drivers should bid on rides, the same way a contractor bids on a job. Uber then selects the low bid and computes the price for the customer.

In that case however, drivers would need to have the tools to accurately estimate their costs, such as knowing the time and mileage from where they are to where the rider is and then to where the rider wants to go, just as a contractor needs to know how much lumber he'll need before he bids on framing an addition to a house. And if he's wrong, he generally needs to eat the cost of his mistake.

Well, the rest of us will likely die. However, you (the reader of this comment) will only have observed universes in which you don’t die. So, due to quantum immortality and all that, you’ll figure it out I guess. And in some sense humanity will not fizzle out; at least you’ll carry it along.

It is a big project, but don’t worry, you’ve got quite a while to work it all out. I would start working on it in earnest in about a million years. If you wait a couple billion, more of the stuff in the universe might have decayed, and the end result might be less interesting, I guess.

Please tell whatever else is around about the rest of us!
