> But higher orbits are just higher speeds and when two objects collide and break apart some smaller fragments might fly off with speeds far greater than those of colliding objects.

Objects in higher orbits are slower[1] than objects at lower altitudes, and debris from a hypothetical collision between two high-orbiting objects would not accelerate to a speed "far greater" than the originating objects, because that increase in speed would require some form of acceleration. One satellite smashing into another would not add sufficient energy to the debris to alter its speed significantly. Any change to the speed of the resulting debris, if it were to occur, would also necessarily alter its orbit. The object's speed and its orbital altitude depend on each other.

> So failure at very low orbit might add a lot of debris to higher orbits that might trigger Kessler syndrome.

It should be noted that "failure" does not mean "exploding into a thousand pieces", so a malfunctioning satellite by itself is not that much of a problem. Low altitude satellites such as Starlink are actually better from a space junk perspective — their altitude means the effect of atmospheric drag on the spacecraft will eventually (within months, sometimes) cause it to re-enter the atmosphere instead of just hanging around in Earth orbit forever, like dead satellites do at higher orbits.

Kessler syndrome would be more likely to occur with satellites in medium and high Earth orbit, since there is no drag to bring the dead spacecraft or debris back down to Earth. Anti-satellite weapons are particularly dangerous here, because they're likely to target high-orbiting satellites and leave debris fields behind.

[1] As pointed below, in terms of pure kinetic energy this is not correct. I was referring to apparent speed vs an object in low-Earth orbit.
There is often a speedup, but maybe not by orders of magnitude. I've usually seen 2x-3x or so.
That’s not obviously true. Apollo crested 5% of the budget, and the crazy USA health care system already consumes 17% of GDP. There’s a reason Nixon wound NASA down.
It matters to the guy paying the AWS bill... or anyone who cares about their ecological impact. We have a duty to utilize resources as efficiently as possible, no different than anyone else. Building every new project on top of a mountain of abstraction that pushes resource utilization to few orders of magnitude beyond what is actually necessary to do the job is financially stupid at the least and socially irresponsible at worst.

If you're an auto manufacturer and you discover something like fuel injection that will dramatically improve efficiency for your customers (the people paying that bill), not doing so makes you a terrible engineer. The 'developer velocity' argument is pure BS... there's absolutely no direct (or even really indirect) correlation there. If the ones you have need someone else to write 9 libraries so that they can build a REST API, you need better engineers.
TPUs are hard to use outside of Google, (I have tried in and out of Google). I think the situation is improving, but the efficiency from using a large pod is really remarkable. What topology did you train AI models on? Within Google it's common to train across a whole pod or even across multiple pods
8x16x16 is the largest currently.

Also if Tesla actually published numbers on an MlPerf benchmark, I would be more inclined to believe claims about 36x better efficiency.

https://mlcommons.org/en/training-normal-20/

The fastest times I'm seeing here for image classification and for object detection (not the same, but probably closest proxy out of the tasks benchmarked) are for TPUs.

To know who has better training technology I don't think you should be using a cost-efficiency metric, it seems to me the best thing to use would be who can train networks the fastest. Cost metrics are easy to game especially if you are the ones making the chips (Of course them making chips is cheaper than buying Nvidia chips for them once the capital investment is made). To measure who is ahead in technology, I think you have to look at who can train models the fastest, and right now as far as I can tell, TPUs are unbeat for this. (Although practically speaking it's hard to pull off these large topology things externally and there are also other caveats with ML perf related to how the training setups are optimized, but nonetheless, it's a better signal than what Elon says in a presentation :) )

You might want to check the accessibility features of iOS: https://www.apple.com/accessibility/
And as far as safety scores, my point is that the safety score is calculated incorrectly because of obvious false positives with "close following". I'm talking being nowhere near a car, getting an alert that says I'm following too close, and that dropping my safety score. I understand why the bar is high, but at this point I honestly suspect there is some tomfoolery going on with how that score is calculated.
This just seems totally unreasonable. You can't ask people to work for no pay, or to live off rice and water.

If it’s a hindrance to you getting things done—to your access—that’s an accessibility issue. Accessibility that benefits you doesn’t imply anything about you, it’s an affordance for you to get whatever you need out of that access.

For example: video transcripts might be a benefit for people with auditory and/or visual impairments. But they also benefit me because I prefer not to consume video content the vast majority of the time. They help me access content I’d otherwise probably never consume. That’s… accessibility too!

For the full story, I was trying to reduce the boot time on my Linux system. One of the things that takes the most time is systemd-random-seed. From what I understand, it takes this long because my computer is not generating entropy fast enough, so it has to wait for a while.

The solution to fix this is to find a way to generate more entropy. The system doc on random seeds has lots of information about what you can use: https://systemd.io/RANDOM_SEEDS/.

One of the options is RDRAND, which my CPU can do. But after reading a bit about it, it seems that some people are supicious of RDRAND. I have no idea if I should too, and since it was disabled by default on my distribution, I decided to keep it of for now, as I don't really understand this subject.

At this point I wondered if any hardware RNG existed, and found the OneRNG, that seems like a cool project, so I posted it here.

This is not a recommandation to use OneRNG instead of RDRAND, I don't know enough about this domain to suggest one or another.
I would actually say that you have gone about the process in the wrong order. That is to say, you should start off by talking to your clients /first/. Figure out what their problems are. Collect all of that.

Then, come up with a concept tailored directly to their problems. You probably need no more than a 1-3 slide deck to show this to them and figure out whether the concept is desired by your end customer.

Finally, and only once you've validated that the concept is desired by your end customer, you build the product.

The problem with doing it in the order you've mentioned, is what happens when you go and show your product to a customer and they say "Nope, I don't actually have an issue which your product solves. Thanks but no thanks."

Sales is the beginning, middle and end of your journey as a founder. Building the product only comes in over time once you've found something worth selling.
I’d honestly be curious to know why you think this is flamebait. Who am I flaming here?

Good point. I have not even driven a car in the last 3 years myself.

Didn't Torvalds have an epic rant on ECC memory at some point?
I'm not uniformed, I am aware better solutions don't currently exist for the frontend.

This however is a thread about using TS/JS on the backend as a web server and I think you will find all my arguments perfectly valid in that context.

Saying "Javascript tooling is better in 2022 than in 2000" is a useless statement even if true when saying "Javascript tooling is vastly inferior to JVM tooling" is also valid in 2022.

Just because it's better than it was doesn't make it good.
This is a research project. There are no users and probably won’t be in this form. If it makes it into a real product, it might not even be done by Google (since they’re open sourcing it.)

I've had memory errors make many directory entries disappear in one directory on XFS, noticed only months later. When you write out bad data and the computer says everything is fine, you won't necessarily be able to get your data back.
Agreed, Intel's policy is very bad for consumers. ECC should be everywhere. It should only cost 1/8th extra.

If you're a new developer who happens to be focusing on PHP, seeing senior folks criticizing PHP as a language should make you question why they're doing that, and research their claims to see if they have merit. Some will and some won't. Taking someone's Twitter rant against some of the specific oddities of PHP as an assault on you personally seems like an opportunity for personal growth we should be encouraging, and not turn to coddling people like they're children. And the same could be said for JS on the front end, JS on the backend, C or C++ or Rust or Java or any number of languages.

Approaching others' criticisms with an open mind and trying to disprove them will make you better than trying to hamfist it into a claim of gatekeeping where there is none.
TL from the project here: you are absolutely correct. KataOS is for embedded systems research, whereas Fuchsia is more of a batteries included system designed for consumer devices.
Okay, then you should fix your mistake and edit the post or issue a new post that does not call or imply that “KataOS provides a verifiably-secure platform” since it does not. You have achieved that when any new readers of the post do not mistakenly believe that it is currently verifiably-secure.

I don't agree with that characterization. I've never been in denial that some people have lost their jobs and other professional opportunities in this way. For example, I said, "Cowardly people in power would rather throw their colleagues under the bus than experience any bad PR whatsoever." That's an affirmation rather than a denial of cancellation. (One of the fastest ways to get cancelled in the United States, ironically, is to criticize the government of Israel.)

The point of my original comment was to correctly attribute blame for the occurrence. I understand that Twitter loudly calls for some people's heads, but there's no legal mandate to act on the basis of that. Tweets are no substitute for thoughtfulness and due process. Which is why I said:

> they could easily fight it if they had the backing of their own employer, for example, who would be the very organization that's officially doing the "canceling".

My goal was to put the focus on the people in power, the ones making the final decisions. The ones who can say "You're fired." Ultimately, it doesn't matter if thousands of people call for you to be fired, as long as none of those thousands is your boss. To the extent that leaders cave to Twitter pressure, those leaders empower and incentivize "cancel culture". The culture could not thrive unless the leaders abide by it.

To be fair, Twitter can raise legitimate complaints. Historically, the powerless have been routinely subject to cancellation. Black people, women, et al. Twitter has given formerly powerless people a public voice they never had before, which can be a force for good. And some of the targets of Twitter scorn truly deserve it.

But again, Twitter is not decisive on the matter. You mentioned Harvey Weinstein: he was convicted of crimes by a jury in a court of law, where evidence and testimony was presented. That's why he's in jail. The court of public opinion doesn't have that power. Moreover, Twitter is the ultimate in slacktivism. It takes almost no effort at all to tweet, and you don't even have to leave the couch. So in general, Twitter "mobs" ought to have less weight than, say, in-person protests. Of course, protests can also be ignored by those in power, but at least a protest shows a significant amount of effort and determination in support of a cause, vastly more than a tweet.

In the abstract, I'm personally ambivalent about "cancellation". I think that some people have been treated wrongly, but I also think that other people deserve to be removed from positions of power. Which is why I said:

> I should note that I'm expressing no particular opinion about whether a particular person should or shouldn't lose a particular job or financial benefit.
The biggest boon of JQuery back in the day was that it abstracted over all the browser variances, which were far more numerous at the time.

Also many APIs simply didn’t exist(e.g. querySelector).

Now that browsers are much mor standards compliant and there are much better APIs it feels like the rationale for jQuery has shrunken to pretty much zero
So Wikipedia should enforce its standards of verifiability strictly, but there's no reason to use the standard of notability as a proxy for that.

If Wikipedia ended up often having to say "we're going to delete this content because it isn't verifiable, even though its subject may well be notable enough for our current standards otherwise", I don't think that would be a problem in itself.

Are there news articles, peer-reviewed journal or conference papers, published books, etc. discussing Session messenger? If so there should be no problem establishing notability. If not, you can wait until some future time when Session messenger either (a) gets more popular and makes enough mark on the world to be noticed outside of first-party marketing statements and blog reviews, or (b) fades into oblivion.

If Wikipedia had an article about every start up company, every product, and every software application, it would be filled with unmaintainable / uncheckable marketing spam. (To an extent it already is.) Wikipedia’s goal is to be an encyclopedia, not a software project directory.

Note that there’s a somewhat different standard between establishing notability vs. verifying particular claims in article content. Primary sources can sometimes be used for the latter. But it’s also plausible that the Signal article doesn’t establish all of its claims to the satisfaction of Wikipedia guidelines.

Maybe I can grant some tiny positive value in that if I have an interest in one of these women, I can now go get a tiny amount of additional information about them.
Hi there - one of the few pro sellers on HN here.

You're planning on prospecting into one of the most rejection-heavy domains out there with small physical business. These people get dozens of calls per day from companies they've never heard of - many of whom are trying to rip them off - and even the best ones (Groupon, Yelp, google ads, etc.) are basically just rent-seeking. Oh, and most have gatekeepers who don't care the slightest bit about your pitch.

Because of that I'd stay away from all this "smile and dial" advice. You'll have no chance. Go out there and hit the pavement and meet these people at their establishments at off hours. If you catch the owner in there at a good time - do your best to inform them of your products benefits and come up with a really good offer to get started (something that loses you money and time). Free Trial, free month of services, whatever makes sense based on the context of your business. The goal is NOT to make money or build a book of business at this point - it's to get a person happy with your software to sell to later.

If the owner is too busy or whatever - have some stuff printed out for them to read later that you can drop off. Ideally with a small gift (coffee, food, candy, etc.) and come back in a few weeks to see if you catch them at a better time (again with a gift, until they talk).

A solid entry level book would be Fanatical Prospecting by Jeb Blount.
