If your product is a battery, why not completely replace the car battery with it? How exactly does it work? I'm assuming you've already patented it, so there should be no harm in revealing more.

If using one of those magneto-mechanical devices of yours reduces energy consumption by 70%, why not use two and reduce it by 91%? Or four to get a 99% reduction?

Edit: The sibling comment raises a good point about bicycles. The cyclist is already acting as a motor, so just put your battery between them and the wheels. Then you can reduce how hard they need to pedal by 70-91% percent easy, right?

In fact, you could just buy an electric motor, put your magnetic battery after it, and have it turn a generator. Since the motor would be using 70% less energy than normal, it and the generator wouldn't even have to be very efficient to output more power than you put in. Then you can just plug it into a wall socket and sell electricity back into the grid...

Or you could divert part of the output power back into the electric motor, so you wouldn't need any power from the grid at all. You'd just be outputting clean, free electricity...
If you consider display/battery/cameras/mechanicals, then by weight/volume/cost, most of the phone is designed in Asia.
Can we trust TikTok to explain in detail how the surveillance part works? Or to remove it entirely?
1. No, anyway, your phone would have to be engineered to be non-magnetic to the same level that you wish to make measurements.
2. Yes, faster is better. Flying lower is also more specific if you have a sufficiently good magnetic map.
Its bugs me as well
Besides power management, this is one of my biggest bit peeves with Linux distributions now.

I don't understand why there isn't a single distribution that offers a full Secure Boot implementation or LUKS Encryption with a password sealed by the TPM out of the box.

Also, there seems to be a lot of misconception about what Secure Boot does, unlike what the name implies, Secure Boot doesn't inherently provide any extra security or protection. It's just a mechanism to sign the software running on the system.

To make the most out of Secure Boot the distributions would need to sign and lock the boot-loader, kernel, and initrd, Then they could seal the LUKS encryption passphrase using the TPM, so if anybody tries to run any unauthorized software, they wouldn't be able to access the data on the drive.

It would be very similar to what windows does with bit locker; your hard-drive is automatically decrypted on system boot without entering any passwords.
Yeah I was going to comment that this could boot headless EmuTOS, but the choice to put the vectors in ROM means it can't.
Author here. I really like the rosco-m68k! I never intended my project to be a "competitor"--one day I saw that Jameco was selling 68000s, ordered a couple, and designed this board to "scratch an itch" and learn about the 68k. It was a quick and dirty project, hence the cut corners w.r.t. memory map and ROM fixed at 0x000000.
Yeah exactly people do the same thing. There's good evidence that for the most part, our actions are driven by our "non-sentient" mind, and our sentient brain just decides justifications to explain a cohesive story as it goes along after it happens.

"Why did you do that?" -> attempt to make up an answer that will be believable both to self-identity and to the listener.

So what's the point of the executive mind if the hindbrain is doing all the walking and talking?

The primary benefit of this story-making is that it allows formulating predictions and discarding the least probable. When a believable prediction kicks in, the predictive brain incentivizes the hindbrain with a partial taste of any reward or pain, with promises of more should the path transpire.

Everyone speaks their own idiolect, and it appears you have used your idiolect to interpret “Existing open source funding models don't work for small projects.” I suggest putting more effort into guessing what the author might mean before writing off the article with snark. After reading the article, I think it’s clear the author was referring to small projects being able to receive funds.
We probably have (at least in part) Apple’s iOS enterprise success to thank for this. No procurement manager is going to sign off on a fleet deal for 10,000 phones without some long-term support assurances.

Google seems completely uninterested in servicing that market with hardware. They could’ve absolutely dominated e.g. aerospace MRO with Glass + pixel tablets but instead most companies are just building iPad apps.
> Is there any real reason why Tesla should be worth more than the rest of the US auto industry combined?

I think this is like asking "Should Amazon be worth more than all e-tailers combined?" circa 2009. Both of their businesses are growing in tangential directions to their core business. In just about 5 years, AWS turned from some "nice supplemental income" to becoming the company's new core product.

The Tesla bulls are betting that Tesla's energy collection and storage products will grow to eclipse their car business and take advantage of the economy of scale of the GigaFactories. The bears are only looking at Tesla as a niche car company.

I'm absolutely not pro-GAFAM or anything, i don't use 99% their products, i've even left gmail recently (android and Youtube are the only GAFAM products i still use).

I don't think market cap is a valid mesuring point. Assets, real-world assets i mean, should be. QE since 2008 is inflating the stock market like crazy - with expected consequences regarding property prices - and market valuation are crazy. If they were not, at least some LBOs attempts would be made. I have found this[0] for revenue, this is an OK metric, not the best for sure, but it show the company participation in the economy (and thus is still better than market cap).

Nostalgia might be a factor.

But I think the bigger appeal is that a system like this can be understood in a much more complete way than what you can achieve with a Pi or even an ESP32.
This is a game for two. Politicians try to score soundbites. Businessmen try to obscure misdeeds.

Amazon admitted to using aggregated seller data for competitive purposes. That's not illegal, but it should be, and congress should fix the gaps in the laws. Since Bezos doesn't want this, he dragged the conversation into the weeds (the aggregated/non-aggregated distinction and the proving-a-negative discussion).

That's fine. Everyone acted in their self-interest, as expected. What confuses me is how ridiculously effective the diversions were. This thread is full of people chasing the chaff. People who ought to know better.

Project author here, I agree. This was a toy project that I allocated a fixed amount of time to, hence the cut corners. I'm working on another design that uses programmable logic to handle multiple interrupt sources (yes, including an NMI button) and allow either ROM or RAM to be banked into address 0.
Right, which is why this is always done as part of a cost-benefit analysis. Sometimes the cost of not paying is far greater.

And yes, paying the ransom signals that hostage-taking can be profitable, but not paying it signals that you value crime prevention over the lives of your children, which isn't necessarily a reputation or circumstance you want, especially when they'll very likely end up brutally murdered.

A company that decided principle-based crime deterrence was more important than granting customers access to any of their funds for 6 months would probably go out of business quickly. Also, try using that argument when talking to people who live in areas largely run by organized crime.

I am all for pursuing fusion, for pushing borders of our knowledge.

At the same time, concerns are way overblown about fission. You know, it is regulated to 1/10000 amount of radioactive increase that is known to ever cause harm.

This is causes the designs to be order of magnitude more expensive then they could be. For example, for BWR, fukushima, there is no graphite inside, and reaction is going on only when water is present. There is no reason to have super expensive air-tight building around it.

Moreover, in fukushima case, the fact that it was airtight actually caused it to explode, as hydrogen formed inside it. Should there be ventilation, there would not be chance for it to explode and disperse material further than otherwise.

Secondly, unneeded evacuation actually caused ~1k deaths when they were removing patiends from life support equipment, for example.

As for the waste - it is again purely political problem, you can totally reprocess it, as they do in France and they end up with a few slabs of glass for 30 years of powering Paris. Even if you dont reprocess it first, it takes ridiculously little space, and never harmed anyone.

Compare coal - 14000 tons of coal daily. Just imagine that, and compare this to the fact that it is possible to store _all_ nuclear waste right _on site_, ready for politicians to come to their senses. :)

To look at it this way, most dangerous nuclear plant is the one that does not get built, as it will be for significant part will be replaced with something burining dinosurs.

808x also had architectural consistency/continuity with the popular CP/M systems that already existed. 68000 had continuity with nothing.

Motorola had a habit of throwing away architectures when the new thing came out. 6809 was only assembly level compatible with the 6800. 68000 was completely different than the 6809 & 6800. They pushed the 88000 as the new hotness to Apple, NeXT, etc. but it was a total failure and the new hotness became PowerPC. At no point was there backwards compatibility. Apple had to engineer their own solution for 68k -> PowerPC migration, and it was crashy.

Intel just kept plodding along with the x86 instruction set forever, keeping customers in a constant -- if ugly -- upgrade chain, until they made the Motorola mistake with Itanium. They smartly backpedaled from that, though.

68k still had half a chance in the late 80s, early 90s -- not to own the whole market, but to have a crack at a segment of it but Motorola flubbed it. Coldfire is really good, but was too late, inconsistent with their PowerPC strategy, and targeted towards the embedded market.
> The expected value in tech startup investment is also negative, I'd suggest. Just like Vegas, all the rational players are really just gambling on the 100x jackpots

Expected value is precisely the quantity that says that the value of a 3% chance of 100x returns is a 3x return. Also, how can you say that the expected value of investment is negative, but that the rational players are gambling at all? Perhaps you mean that the 3% chance of 100x (or whatever) is irrational for the founders, which may be true, but that isn't really what your words say.

You can do all this in C but it's super hard to get your brain around and do it right. It's probably better to use an abstraction.

For example, the Pony language is written in C and guarantees no races or deadlocks without using locks or mutexes so it's faster than C with locking. The user defines intentions, similar to Rust's borrow checking, and strict compile time analysis makes it happen for you.

I termed this model "microsubscriptions" when I was pursuing it in the context of website funding.

There are difficulties.

Gaming the system

Folks will absolutely distort their software, buy fake github stars, spam out bazillions of typosquatting packages etc. We know this because there is already a weak financial incentive to subvert: supply chain attacks for cryptominers. Direct cash will be a much stronger incentive for fuckery.

Banking

In general, financial institutions don't like services that aggregate and transmit funds. They attract extensive regulatory burden and more importantly, they attract fraud and chargebacks.

Chargebacks and fraud are expensive to deal with, banks hate it, so they generally tell you to just sod off entirely.

Regulation

You are on the hook too. Anti money laundering laws are complex and can come with criminal charges for failures. Taxes are complicated and you need to keep correct books. Got it wrong? Too bad, you owe the taxman cash you don't have.

Credit card money laundering in general

This is where someone with a stolen card uses your service to launder money taken from it. They sign up with the card, patronise their own software, then run off with the cash. Later a chargeback arrives which is levied against you, not the attacker.

The easiest defense is to limit the subscription amount, so that an attacker with a stolen card can't benefit much. But they can still use you to test that the card is active. A second defense is to hold the funds for a period of time, so that you can pay chargebacks. Even so, you will be looked at poorly by any banks or processor companies if your chargebacks pile up, regardless of whether you could cover them or not.

Trusts

This one is the biggest mistake I see, and I see it again and again.

If you receive money from person A so that you can pay it to person B on A's behalf, you are a trustee. You generally don't need a document to become a trustee and you don't even need to intend to be a trustee. Trusteeship arises from the facts.

What does trusteeship entail? Fiduciary duty. That is a high bar and you almost certainly don't meet it.

Mingling funds from multiple donors without incredibly scrupulous accounting? Problematic. Mingling donor funds with your own funds? You're in deep shit.

Further: trusts have purposes, which the trustee has to abide by. These again can arise from the mere facts. If you said you would take funds from A to pay to B, that's all you can do with it. Can't find B? Stiff shit. B doesn't want the funds? Stiff shit again. You now have money that is like radioactive waste: it's dangerous, you are responsible for it and it won't go away.

----

In general I like microsubscriptions as a model for some things. I spent a lot of time, emotion and treasure on doing it myself. But it is harder than it looks.
Much of that is answered in the article.
Not IBM. The Macintosh. The Macintosh came out with a good GUI bolted onto a DOS-type OS. No processes, no threads, no swapping, no paging, no hard drive. The Lisa had all of that, but cost too much. However, it was actually useful. The Mac was a money-losing toy until it got better hardware, especially a hard drive and more memory, in the form of the Macintosh SE. But then Apple was tied to an OS cut down to fit the original 128K floppy-only machine. Which they stayed with far too long.
A startup is a difficult environment to try to rewrite the laws of physics. Consider either joining a research lab, or starting your own and applying for SBIR funding instead.

If you want to work on this in a startup, don't start with electric cars! You need several billion to launch a competitive electric car today. You can't raise that without a track record of previous successes. Start with something small you can build multiple iterations of on a startup budget. Electric scooter and bicycle owners also care about range.
One of the projects I had in mind when writing this post is the "color" module on npm. It's a fantastic utility for reading in colors in different formats (hex, decimal, CMYK), applying transformations, and getting a modified color back (in your format of choice).

For all intents and purposes this module is "done". It's extremely mature and has already implemented everything it set out to do. It has 3.3k stars and 8M monthly downloads.

When I look at your list of proposals, none of them really apply to "color". The projects you have in your head are big, ambitious projects, not the smaller utility projects I describe in the article.

Well, it depends on the numbers involved. If they estimated a 5% chance of getting $2 billion, then that would be a 2x expected return on a $50 million cost, which is entirely rational for investors with huge pockets. But if they estimated a 1% chance of getting $2 billion, then that's a 0.4x expected return (an expected loss of $30 million), which is irrational, unless the "embarrassment" is a significant factor for the VCs, and that would be interesting.
No, that was the case for the old Windows RT devices (see that 2012 in the URL…). With the modern ARM devices like the Surface Pro X, the Microsoft requirement is like with x86: required to allow disabling Secure Boot.
