Gear ratio *is* the critical component, specifically prop pitch vs. forward motion, but not exactly for the reason you describe. Xyla Foxlin built a working model and provides a bit more info here:

https://youtu.be/VUgajGv4Aok?t=432

In short the working model she built has approximately a 2:1 ratio between forward wheel motion and propeller pitch. IOW if the propeller pitch is 5" per revolution, the wheels will require 10" of forward travel to spin it one time.

Yes, you can do this with Mercury. Mercury's orbit is chaotic, so even modifications in its position on the order of millimeters can build up to produce completely different long-term dynamics. In particular, there's a few percent probability that Mercury will get ejected from the Solar System before the Sun dies. [1] It's also possible that Mercury will collide with Venus.

Thanks for the link to the previous discussion. Looking at the numbers in there, I don’t see how this conversation isn’t about overpopulation. We need such massive equivalents of land because there are too many of us, and we value living high quality lives (high standards of living with substantial consumption). The alternative is that everyone lives very constrained lives but I don’t think that is feasible or even desirable.
Starliner still hoping for August launch despite technical troubles
Right, but the argument is that the CEO person and salary are mismatched, I think -- not necessarily that the salary is inappropriate.

A CEO needs to earn their keep. Baker does not, and somehow keeps getting increases while there are zero metrics on which the organization is improving.

Feels like nobody here has bothered to read the actual technical specifications.[1]

This already adds new level of encryption into iCloud stored images. They have essentially created E2EE system with a specific access (or backdoor), while preventing the use of backdoor for other purposes than CSAM (so nobody can ask randomly to decrypt something else). They can only decrypt images, when user's account reaches the treshold of CSAM hash count:

> Only when the threshold is exceeded does the cryptographic technology allow Apple to interpret the contents of the safety vouchers associated with the matching CSAM images.

While this is not perfect end-to-end encryption solution, it is better than only server side encryption. Now there are two levels of encryption. If someone breaches Apple's servers and they have also access for server side private keys, they still need matching NeuralHash value to decrypt the images.

So there is a major uranium producer in every corner of the world? That's better than oil and many elements critical in electronic. Like whats your benchmark" it cant be as common as dirt.
Historically, taking a position against measures which (even if only nominally) stop CSAM because they have abstract, negative privacy consequences is difficult. Try to explain to the average person why Apple's decision here is ominous, and the first question you'll get is "wait, why do you want to protect child abusers?"

I've been getting angry about this for the last week, and am just now getting to the point where I can accept the reality that the snowball is already rolling. The government isn't going to step in and prevent this, unless it's to make the backdoor larger, and nobody who was going to buy an iPhone or use iCloud is going to stop because of this. So, it's done. Apple will put a backdoor on your phone and yes, and obviously that backdoor will eventually be used for things beyond the scope of what they're telling you now.
> In other words, the considerations are completely unrelated to everything you're implying.

Discrimination and bias are often unconscious, rather than an explicit decision.

Suppose that YC was biased against X, and that therefore the startup pool you can select from contains mostly ~X. You could select for interesting, substantive startups in Meet The Batch threads, and it would still reveal the absence of X.

Uber has between 3 and 4 million drivers compared to 29000 employees. If you follow the HN and Blind comment threads there is substantial belief that they could survive with half to 1/4th that number.

Even assuming that only 10% of Uber drivers care about advancement and learn to code that would create 300k new software engineers, far more than Uber could ever hope to employee. In fact this would be more software engineers than the total number of engineers employed by the top 5 tech companies by market cap.

Whether or not you subjectively think it is pointless or not, the well-established meaning of “progressive” and “regressive” taxation does loom at income.

If you want to invent your own terminology to reflect the considerations you believe are important, great, but overloading established terminology used consistently by people with varying normative beliefs about the subject matter to mean something completely different because you don't like the way it maps terms on to facts isn't helpful in communication.
Nothing in itself is going to do enough. We have to decrease emissions significantly, so that has to happen by making lots of small cuts.

Heidegger is against it, yes, but he's also clear that we're stuck within technology as a historical destining of Being. We can't just escape technology by thinking differently about it, but must wait heedfully for the historical development of Being (as he lays out in The Turning, just after QCT). In fact, the fulfilment of technology's own reductionism is a necessary step, as only the full concealment of Being in technology allows us to recognize that oblivion for what it is and thus to overcome it. As such, I think it's a reasonable argument to make that AI taking away the work of ordering for humans may help us escape the incomplete agency of ordering the standing-reserve so that we're no longer forced to merely see the world as standing-reserve.

By the way, I saw your comment about Heidegger and Asian religious philosophy below - are you familiar with the Kyoto school? I've signed up for the Halkyon Guild's upcoming course on Nishitani Keiji, and am vaguely hoping his theory of the self-overcoming of nihilism can be brought to bear on the questions Heidegger raises about technology.

Germany, the aggressor, had a substantial chunk of France and Belgium in their control at that time, and were, for all intents and purposes, winning the war from defensive positions. They had no incentive to initiate peace talks. Had the French or British initiated peace talks, it would've been essentially a surrender, and involved the loss of territory.

There was no way that either side was going to budge when that was the status quo. When the Hundred Days offensive kicked off, and Germany was being pushed back on the Western Front, and with their home front on the brink of collapse due to blockade-induced starvation, they did indeed initiate peace talks.
I think we're also forgetting that adoption of nuclear power is also dependent on a stable government. Geopolitical risks probably outweigh all the drawbacks mentioned.

I don't know who should be Mozilla CEO. But I know that the current management is failing in unexciting and repetitive ways.

Someone with new ideas should be Mozilla CEO. Someone who believes in the mission of the organization, and will use the organization's vast resources to chart a new path that respects that mission.

An executive search would have no trouble finding quaified candidates at that pay level. They might not work out either. But failing in the same way, over and over, is silly magnified to horrifying due to the importance of Mozilla to the web and the public.

I don't entirely agree about Eich. He was respected in the org, and obviously has ideas that exceed Mozilla's charter. A CTO is limited in their strategic scope, so I don't think his years working for Baker indicate he would fail in the same way she has.
I know HN has special rules for formatting certain URLs. Like Twitter links get the username added on and apparently research.google.com gets a subdomain (Or maybe all of Google?).

@dang: if it isn't too unwieldy, maybe colab links could have the 'colab' part added on too? The way it is now led me to think the link led to an official Google Research publication/project.

The delta-V is around 16km/s.

For high-efficiency chemical propulsion (e.g. hydrogen - which, note, non-storable!) that's about 3.5-4x the exhaust velocity, meaning around 98-99% of your spacecraft's mass needs to be fuel.

For electric propulsion (which has issues because of low thrust and electrical power requirements), it's only about 0.5-1x the exhaust velocity, so only maybe 50-70% of spacecraft mass needs to be fuel.

In any case, it's a LOT.

This!

I was hoping for a list of logic and organization / structure errors.

On the idea of editor feedback, one thing I find frustrating is that hardly anyone teaches how to read error messages and stack traces. That’s the most important thing because as a beginner you make tons of errors and you see them a lot! Books and tutorials don’t show any errors, so when you inevitably make one it’s hard to figure out what exactly you did wrong.

sigstore will be a non profit / free to use service. Think Let's Encrypt for software signing.

My hope is that we shift the paradigm so that consuming untrusted software via packages / dependencies etc becomes as unappealing as serving a website over just plain ole HTTP has now become.

In order to make that shift, open source communities require a free and easy to use service and this is what we hope sigstore will become, which is why it's a Linux Foundation project with all code being developed and maintained by a community.
This is a very solipsistic way to look at the world. FOSS has no duty to try to appeal to you personally, and if you accept the end of your privacy over UI niggles, that's your choice to make. The reason Apple can spend so much on UI is because of your willingness to eat whatever they serve you.

After emancipation, there were plenty of slaves who wouldn't leave the plantation, and became slaves-by-another-name in the sharecropping system. I don't think any of them were so up their own asses that they blamed the slaves who left for not making it easier to leave.

Also, RMS didn't talk about "FOSS." He talked about the inevitable future if we continued our trajectory, and suggested Free Software as the solution.

I don't fully understand that chart, but it seems like it's showing that it's harder to get to smaller planets than larger ones - i.e. takes more effort (fuel) to get into a smaller planet's gravitational pull, but you get a lot less benefit since the gravitational pull is less. Is that a reasonable assessment?

In this case they are actually "consuming" more wind. A normal sail "consumes" wind by taking moving wind and reducing its speed to 0. This "consumes" wind by taking moving wind and sending it back the other direction, so it creates more thrust per unit wind.

Apple says it will reject government demands to use CSAM for surveillance
Sorry. Either the posts got updated or I got the thread confused as others were trying to say that (re: hash versus classifier).

Re hashing, Apple claims 1:1 trillion likelihood of a collision. These kinds of systems are not rolled out lightly, and even if that number is wrong, it’s feels unlikely to me that it’s too far off. If it is and it has too many false positives, this will get noticed and the system pulled until it’s fixed and at the required false positive rate.

Ultimately beyond Apple if you’re getting arrested and confront a judge, you’d expect humans at that point to look at the evidence. In fact, I’d expect the DA or whomever to similarly look at the photos at that point. You can’t be sentenced without evidence in the US legally (how all of this works in another country is another matter).

If there is legit porn that’s 18+ mixed in this database, and someone ends up being charged because of it, fights, and wins, I’d expect a number of counter lawsuits to follow. To me it seems incredibly unlikely that non-CP is not only going to be a significant part of that database (including 17 year olds versus the more likely 7 year olds), but you’ll be saving it to your iCloud photo roll. There’s so much legal porn out there, in such vast quantities, this hypothetical situation you describe I’m not sure will ever actually occur.
