You would need drivers to cooperate. I believe it is hard finding truck drivers as is. Isn't that why its an industry where there is very high percentage of owner-operators? Imagine you now tell them they'll not even be doing the majority of the driving and 80% of their profit will go to the companies that automate the easiest part of driving. They're not going to like it. So as long as you need human drivers it's not going to happen (unless there is a huge recession and high unemployment, then people will take any job)
This assumes superconducting wires everywhere. I don't really see it happenning in microelectronics for example. You'd have to replace the entire silicon ecosystem with this new material. Not happening soon, probably never.

But sure, for specific applications an increase to 'near 100%' efficiency could have important secondary effects, eliminating heat-sinks, etc.

Now, one rider at our horse barn has organized a soup kitchen, been active in the anti-war movement, and got arrested for trespassing at a military base but she has spent time in federal prison.

It is the same in the "hacker underground", if you ever admit that you have been involved in illegal activities online you are quite likely to get hacked right away. In fact it is a lot more likely you'll get that kind of "justice" than ever hear from the authorities.
Also IMHO it looks horrible.

Show HN: Introduction to Algorithms and Machine Learning [pdf]
From 2020-23 I taught at a highly accelerated math program in Pasadena, CA and was given the opportunity to develop and teach a quantitative computer science track for participating 10th-12th graders who had an interest in CS. I developed the curriculum on the fly while teaching the courses, and eventually consolidated it all into this textbook.

The students had already learned a surprising amount of math for their age using a system that is now commercially available at www.mathacademy.com, where they progressed from prealgebra through AP Calculus BC in only three years (6th-8th grade), and by the end of 9th grade had learned the core topics of linear algebra, multivariable calculus, and differential equations. They often expressed an interest in applying the math they had learned, and given my background in both algorithm development and data science, I became the natural candidate to teach the course. (Incidentally, I also developed the adaptive algorithms for the mathacademy.com system itself.)

The classes began with some basic coding exercises (since most of the incoming 10th graders had little to no coding background) after which we moved on to core data structures & algorithms, regression modeling, machine learning models, and game trees/minimax. The capstone project involved reproducing academic research papers in 90's artificial intelligence – specifically, the papers in the Blondie24 research program, which involved using evolutionary algorithms to train neural networks to play board games.

The program ended last month (I've recently relocated out of state), but I figured the book could be useful to anyone looking to get up to speed quickly in the fundamentals of algorithms and machine learning.

Precisely. Gas cars have had their scandals and crises, I dont have to worry about the manufacturer juicing the fuel gauge for marketing purposes. I have been car-free for the past 12 years, but when it'll be time to move to the suburbs, I'll go with what works and is predictable.
I don’t understand how superconductors will make phones into supercomputers. There is a still the limitation of the number of transistors in a given volume.

Also, how does this help fusion become possible?
The issue is that the EU is (rightly, IMO) investigating based on what humans do instead of what they could do.

Could companies say no and choose a competitor? Probably. But it would take more effort than saying yes, even if the product is worse. It is therefore reasonable to ask whether MS knew that including Teams the way they did would have the effect of killing competition, which is bad for consumers and therefore illegal.
I don't know how I feel about this implementation. On the one hand, I love its simplicity and the fact that you still have Serializable transactions. On the other hand, having conflicts at the page level means that the occurrence of conflicts may be surprising because it's based on this fuzzy notion of having values "close together". Close together changes based on your page size configuration and, as the article points out, is not necessarily correlated with a natural key in ROWID tables. I would be very interested to see this system in use in a few real applications to get an sense of how much this really matters.
You use Javascript though, right?

> If you're running on a PC, there are hacks to 'borrow' the serial number of some ancient imac and have it work still (even ancient systems are still allowed to log into icloud, and those ancient systems didn't do any cryptography so all you need is a valid serial number that nobody else is using).

Hackintosh users have to do something similar to be able to sign into iCloud.

The serial number doesn't have to be valid (as in existing on a physical machine) to work, though. It just needs to look valid (be generated using the same methodology as real serials). In fact in order to prevent accidentally using a serial tied to a machine owned by somebody else, the recommended procedure is to generate a serial and check its AppleCare status to verify that it's not tied to a real machine, and if it is to regenerate and check until you find one that isn't.

any evidence to support that claim?
I understand that... so you're saying something like "unlocking hubs" would not suffice? Or they'd add too much cost to the vehicle?
Small. Imperfect contact, unplugged terminals, etc. These are not 1st year grad students who don't know what they are doing. The authors have decades of research and fabrication experience, and publications to back it up. Comments that insinuate it could be those kind of novice mistakes (other comments on HN/reddit, not yours) are frankly insulting and speaks to a profound arrogance in being unable to accept a new discovery.
If that's true, then it may be a matter of lingering perception. As an ICE car owner who lives in LA, I see plenty of charging stations, but not necessarily when I go on drives of hundreds of miles outside the city. Of course, I may be biased given that I don't need to pay active attention to vehicle chargers. But, for me, it would be a deal breaker if I couldn't be confident that my car could still be fuelled up in Bumf*k, Nowhere.
I rented one for a week and it showed battery percentage not miles. It seems pretty stupid on Tesla's part to show the very inaccurate EPA range rather just battery percentage. And it looks like they doubled down on the stupid with these tactics.

I used to own a high hp gasoline car, and its mileage estimate would regularly be off by 50% when I drove it like I stole it. The difference is that there are gas stations everywhere.

When I drove the Tesla aggressively, it pretty quickly told me I needed to turn around and go charge some more - there were no superchargers ahead of me. You might say I was lucky that I was using navigation for my route, so that it could figure an accurate battery usage. But I wasn't lucky. Of course I put the route into the navigation system. What was the outcome? I didn't go charge it, and instead I stopped driving like a c**t. I made it to my destination and back with 17% charge left.
This dude's portfolio really does not live up to his hype.
This isn't even remotely true.

No, there's no YB and they propose an entirely novel mechanism for how generic metals (a whole host of possible combinations) can achieve superconductivity in these conditions. At least check out the formula or open the link.

> modified lead-apatite (LK-99) structure

> The superconductivity of LK-99 originates from minute structural distortion by a slight volume shrinkage (0.48 %), not by external factors such as temperature and pressure. The shrinkage is caused by Cu2+ substitution of Pb2+ (2) ions in the insulating network of Pb(2)-phosphate and it generates the stress.

It's just Lead, Phosphorus and Oxygen all the way.

Another reason for some a wavy walls involves capturing more heat from sunlight over the course of a day, in this example for nearby plants:

>compared to a device that must constantly have the receiver powered up to listen

But there's no need for the receiver to constantly stay awake to listen or poll the transmitter like in wired network systems.

Low power wireless protocols use time slots since forever, where receivers wake up only in their dedicated time slots to check if any messages are addressed to them, and if so, then they wake up the entire CPU block and start processing the payload and reply to the message, but if not, then they put the receiver back to sleep till their next time slot. Simple and very energy efficient.

Therefore receivers are more efficient than transmitters as transmitters are constantly operating as beacons for every time slot which is what you want when the base station can be powered on AC, while the IoT receivers are usually battery powered and need to last for years.

The only tricky part is building a self compensation mechanism in firmware for the receiver wake-up time jitter as all receivers inevitably start to drift in time as per the drift of their oscillators, including the transmitter which also drifts, especially when using low-cost oscillators with horrible drift.
Ask HN: Can cycling be less CO2 efficient than driving an EV?
The TL;DR of my computation, which is extremely likely to be completely wrong is that in some cases you might be better driving an EV than a riding a bicycle in terms of CO2 emissions during usage, and that even taking manufacturing into account, EVs might still be not that much higher than the emissions of a bicycle.

The reason why I'm posting this here is that I'd like feedback on it.

The gist of it is that EVs being highly efficient, the source of food of the biker can actually make them less efficient than a car in terms of CO2 emissions during usage.

I can post sources for the numbers I describe, but I'm mostly interested in methodological flaws, still, don't hesitate to ask for them if necessary.

Here goes the computation:

Let's start by considering the CO2 emissions required to produce the food that fuels a human when they pedal a bicycle. Suppose the production of this food generates 0.000363 g of CO2 per joule of energy. Knowing that it takes about 110 joules to travel a meter by bicycle, we can deduce that the production of food to support cycling generates about 0.040 g of CO2 per meter traveled (110 joules * 0.000363 g/joule).

Now, let's compare this to a Tesla Model 3. This electric car requires about 0.15 Wh of energy to travel one meter, or 0.00015 kWh. In France, the production of 1 kWh of electricity emits about 100 g of CO2. Therefore, the Tesla Model 3 emits about 0.015 g of CO2 for each meter traveled (0.00015 kWh/meter * 100 g/kWh).

In this case, based solely on the usage of the vehicle or the bicycle and not their manufacture, the Tesla Model 3 is approximately 2.67 times less CO2 emitting than cycling (0.040 g/meter divided by 0.015 g/meter).

However, these figures do not take into account the CO2 emissions generated during the production of the vehicle or bicycle. If we refer to Tesla's 2020 impact report, we learn that when accounting for both the manufacture of the vehicle and its usage, and assuming the vehicle is powered by solar energy, emissions amount to about 0.062g of CO2 per meter traveled.

As for the bicycle, it is estimated that the production of a bicycle generates about 0.005g of CO2 per meter traveled. Adding this to the emissions of 0.040g per meter traveled generated by the production of food for the cyclist, we get a total of about 0.045g of CO2 per meter traveled.

Taking into account manufacturing and usage, the Tesla Model 3 therefore emits approximately 37% more CO2 per meter traveled than cycling (0.062 g/meter versus 0.045 g/meter). However, this comparison holds for single use. If the car is shared among multiple passengers, its carbon footprint per passenger and per meter could be substantially reduced, making the Tesla Model 3 potentially more eco-friendly than cycling depending on the number of passengers.

WDYT ?

I completely agree. I see many people commenting that the document has bad grammar or charts, completely ignoring that they probably authored it in Korean. Also looks like Kwan and HT Kim are fighting who gets to be 3rd Nobel winner so any problems with quality of the layout are easily explained by this.

One thing that is a green flag in my opinion is that apparently they had a sample for a long time (year+) so I find it unlikely they made an obvious measuring mistake.

But as always, most would love to have this be true and sometimes this gets better of us.
Digital (not strictly connected to real) identity is a not a bad thing in itself. But I honestly don't think that digital identity should be managed by governments or corporations, they already have too much leverage over individuals.

I am a bit opinionated about that, because I already saw lots of that in Russia with all these fancy "security" and "convenient" digital tools and how it ended.

Digital Id should be solved by some kind of WebOfTrust, private DIDs and somehow distributed reputation systems, not by centralized government databases. It's a straight way to tyranny.

Just curious, did you ever own a high end vehicle before your teslas?
The main problem with eSIM is that they are still little HSM modules controlled by the carrier. This results in most of the problems that people are complaining about in this thread.

1. You can't swap the SIM yourself because the HSM is designed not to reveal the secrets.

2. You can't provision offline because the carrier needs to encrypt the payload to the target HSM. In theory I guess if the target phone was known it could be provisioned once and uploaded repeated (for fast eSIM swapping between different SIMs in the same device). But there may also be some form of replay protection.

What I would like to see is that the eSIM is just a config file with connection info and credentials. Then the device itself is in charge of connecting, sharing and whatever else. The user is in control and can transfer or swap as they see fit.

The downside would be that this data is easier to steal if it isn't in a TPM but no one said that you couldn't put it into a TPM. It is just user choice now. For example the keys could be uploaded to the TPM much like today. Or it could be encrypted with a TPM key and stored on the device (this would allow easily changing eSIMs or transferring between devices). You could even do things like escrow a copy to a trusted backup location so that you can restore the eSIM to a new phone if you lose or break the old phone. (Although you may need to revoke the old creds if they are at-risk of being stolen from the old device.)

The carrier should be a dumb pipe. I don't like how much control they have over my hardware.

Your comments seem to me to be about how long it took to bring up a new system.

Without agreeing or disagreeing with those, "I'm not going to trust the filesystem on the existing machine" was the choice I was talking about.
I'd guess using uuids for the keys instead of ROWIDs might help. I'd also guess that UNIQUE constraints must also trigger a conflict and that "close together" in index btrees also does. If that's true then using a uuid primary key is defeated by the indices that you'd use to work around it.

> Adding clutches just for allowing the user to push around the car seems needlessly complicated and over optimizing for a scenario that will not occur for the majority of cars.

The ability and need to push a car is incredibly common, especially for emergency or non-optimal scenarios. Cars often stop working, be it dead battery, out of gas, malfunction, broken axle(which teslas have).

There has been more than zero times in my life when I discovered I was in posession of something I was unaware of.

Not often drugs specifically, but I can't say for sure never that either. In my 20's I had friends that spanned a full spectrum, and not all activities were organized and orderly. You go on a camping trip, or even just a night in someone's back yard, you come back with mystery items in your blanket/towel/bag/cooler/coat.
I don't smoke and yet I somehow have been in posession of many lighters at different times.

If someone doesn't understand how that happens, I can only feel sorry that they have lived so little that they never lent a girl their coat at a party or provided the blanket that everyone else sat on etc. But then they end up in a position to decide what constitutes fair and reasonable expectations for everyone else.
