The two cases are just very different, why are you even comparing the case of an investment company buying a stake in an existing app with the original creator being banned from owning what they created?
Sure. I just noted the irony that the US discourse has sounded a lot like "we are better than China, we are more free" for decades.

My read (not an expert) is that you are safe if your rsync is only via secure connections, to & from systems where untrusted parties can neither run rsync, nor play clever games with the files which rsync is accessing.

Which (in my paranoid opinion) is pretty much the only secure use case anyway, for code like rsync.
The 43-byte implementation might define only a subset of the functionality provided by the full VM, enough to "bootstrap" into the full implementation, most likely.

In fact, if the VM is Turing complete, it can theoretically emulate any computation, including its full implementation, even from a small subset of operations.

The point is that the 43-byte implementation does not need to encode the entire VM explicitly. For example, if the VM has built-in primitives for looping, branching, and memory management, the minimal implementation can leverage these to rebuild the remaining functionality.
I cannot argue on the TikTok as strongly but I can see strong arguments on why Huawei and DJI are national security risks. Some of this is more educated guesses so not defensible with numbers. We know most major companies in the Chinese market have extremely close ties to the CCP. No doubt historically the US has gotten companies to put in backdoors or other mechanisms but I believe the CCP takes it to a next level. We know for a fact that the CCP and chinese entities play extremely hardball when it comes to corporate espionage. Some of the stories we have seen almost read like a spy novel. Certainly Huawei and DJI make some incredible products but when you have drones being used to survey the electric grid or other major pieces of infrastructure, I do believe it warrants major concern for national security.

I think you are proposing a much more extreme conspiracy compared to the easier explanation, China is a fairly crafty bad actor in a lot of cases. 99% of the imported products from China are not getting blocked, just the ones that have very significant national security risks.
I tried it for about a 1/2 hr and it was nothing like TikTok in terms of content, UX, or the algorithm. More of a fail than Reels or Shorts, or any other wannabe clones.
thats just mixture of experts
TikTok has entire RoW (excluding India) market. Assuming US only bans in US... which TBH we don't know. There's no comparison because TikTok is still massively profitable without US, whereas US Steel is still a mess without JP.
electricity is not "material" it is energy input.
This is such a fantastic initiative! I love the concept of promoting health and breaking sedentary habits with a global timer—simple yet impactful. One suggestion to enhance the experience would be to incorporate short instructional videos for each exercise. Visual guidance could make it easier for users to follow along, especially for those new to mobility or strength exercises. It would also add an engaging and interactive element to the tool. Keep up the great work, and I’m excited to see how this evolves!
I doubt they have the engineering experience to launch anything at this point. They try to do a weird tiktok like thing where watching a video on mobile will randomly scroll to another video, but I think this probably has more to do with juicing "unregretted user seconds" than anything.
Is it censored, or do most people just not talk about it on Facebook?

It's interesting how incredibly supportive of human rights that a platform in bed with the CCP became, no? Do you think that China's human rights bugaboos are often discussed on their internal social networks?

It's amplified.
> a feature that can only be appreciated by a subculture of people (privacy advocates)

Just because it can’t be “appreciated” by all users doesn’t mean it’s only “for” a small sub-group.

It seems to me they’re just trying to minimise the data they have access to — similar to private cloud compute — while keeping up with the features competitors provide in a less privacy-respecting way. Them not asking for permission makes it even more obvious to me that it’s not built for any small super privacy-conscious group of people but the vast majority of their customers instead.
> I'm skeptical that the algorithm is actually "better" and it's not just that the end users have fed TikTok a ton more data points about their personal likes and dislikes.

I've watched probably 1000s of hours of youtube and it's still pushing crap at me that I would never watch in a million years (edit: eg "How to create Smart Contracts using ChatGPT" or "Abusive tough guy picks fight w the WRONG GUY!"). Maybe it's better if you like a specific genre of video essays or whatever but in terms of a replacement for tiktok it's completely irrelevant.

Reels is at least in the conversation, but the UX is ass and the culture there is a dumpster fire. Granted, I haven't had a meta account for about a decade (the ad obsession just destroys the experience) so this is all hearsay.
In general this is a cool article but I worry when TFA observes that cosine similarity and the dot product are the same under certain conditions (specifically that the vectors are unit vectors). It's really important that people who are using these measures understand something as basic as this. It shouldn't need to be said in an article but I feel (as the author obviously also does) that it does need to be said because people are just blindly using it without understanding it at all.

Cosine similarity literally comes from solving the geometric formula for the dot product of two Euclidian vectors to find cos theta, so of course it's the same. That is to say

a . b = |a||b| cos theta

Where a and b are the two vectors and theta is the angle between them. Therefore

cos theta = (a . b)/(|a||b|)

TADA! cosine similarity.[1]

If the vectors are unit vectors (he calls this "normalization" in the article) then |a||b| = 1 so of course cos theta = a . b in that case.

If you don't understand this, I really recommend you invest an afternoon in something like khan academy's "vectors" track from their precalculus syllabus. Understanding the underlying basic maths will really pay off in the long run.[2]

[1] If you have ever been confused by why it's called cosine similarity when the formula doesn't include a cosine that's why. The formula gives you cos theta. You would take the arccosine if you wanted to get theta but if you're just using it for similarity you may as well not bother to compute the angle and just use cos theta itself.

[2] Although ML people are just going to keep on misusing the word "tensor" to refer to a mere multidimensional array. I think that ship has sailed and I just need to give up on that now but there's still hope that people at least understand vectors when they work on this stuff. Here's an amazing explanation of what a tensor actually is for anyone who is interested https://www.youtube.com/watch?v=f5liqUk0ZTw

That's what it is, but that's not how teenagers perceive it, I think.

I see it like this: if all your friends watch the news everyday and spend a lot of time talking about it, you will end up watching the news as well. To connect.

If all your friends watch a lot of sport and meet for that, you may well end up learning to enjoy sport as well.

If all your friends know the trends on TikTok and talk about it...
But we are, there is no irony. China has the great wall and massive corporate espionage games to steal state and corporate secrets. The US and its various federal intelligence agencies have certainly done nefarious things but never quite as documented at the level as China's. They actively monitor all of their Social Media, block most foreign social media. I can easily go to any Chinese social media/website from the US.
Anyone can be a researcher/scientist if they pass peer review at a reputable journal or conference. That's just how it is.
For real data you can use Gaia ESA archive: https://gea.esac.esa.int/archive/

I went to study MSc in Space Science and Technology as a hobby few years ago. In one course (2022) we had an assignment to find Supernovae from recent Gaia data (Python code). Then made sure this is observable by University’s robotic telescope (and compliant with local weather forecast). Next requested the observation from the telescope and if successful, received the pictures next day. Had to analyse the results as well. It surprised me how much data there actually is available in quite open format from ESA missions.

Controlling remote telescope few thousand kilometres away was also a nice experience.
I'm not assuming. I've worked in hotel management and big third parties don't manipulate their reservations. However it's very convenient for a hotel to blame them when they've messed up themselves, since guests eat it up.

To play the devil's advocate here, as someone who grew up homeschooled and in a culture of "micro-scale evolution exists, but macro-scale evolution has not been demonstrated":

>Antibiotic resistance

...is a micro-scale adaptation, like an organism's immune response. Recognizing it does not require belief in a prehistoric common ancestor for all organisms; it just requires observing changes that happen on a much smaller and more rapid scale.

>Existence of vestigial structures in organism. Why do humans get goosebumps when we don't have enough hair to insulate us? Because it's an evolutionary leftover from our hairy ancestors when the reflex would actually cause hair to trap more air for better insulation.

This is non-falsifiable conjecture about a pre-historic past based on observation of present structures. It is equivalent to "we obviously know that dinosaurs did not have feathers, because their skeletons do not have feathers, and feathers would have made them more visible to predators, so they wouldn't have had feathers."

>Understanding evolution is crucial for crop management. The development of pesticide resistance in insects follows the same principles as antibiotic resistance.

...which, again, is a micro-scale adaptation, like an organism's immune response. You can notice pesticide resistance occurring in pests and rotate your pesticides without having to sign on to the unverifiable claim that this happens because all life derives from a single organism.

>Medical research often relies on animal models because of shared evolutionary history. Our biological similarities with other mammals exist because of common ancestry. Without this framework, it becomes harder to understand why medicines tested on mice or primates might work in humans, or why certain diseases affect multiple species similarly.

This is more non-falsifiable distant-past conjecture based on observation of current structures. Is it necessary to believe a particular set of conjectures about the origins of mammals' biological similarities in order to recognize the fact in front of you that the mammals are biologically similar, and thus some mechanisms of action may apply across species, provided those similarities are retained?

>Human susceptibility to back and knee pain is a consequence of how recent bipedalism is in our evolution. Same for why humans are so prone to chocking, our larynx evolved to enable speech at the cost of making it easier for food to enter it.

...which, again, is non-falsifiable distant-past conjecture that has no bearing on recognizing the existence of the verifiable current-day reality in front of you: humans have back and knee pain. Is it necessary to accept a particular set of unprovable conjectures about the distant-past origins of this particular skeletal structure in order to make decisions about how best to treat a symptom that exists today resulting from the skeletal structure that you see immediately in front of you?
Reminder that TSMC WANTs to stay in TW... they did not want to expand in US at all. Arizona fab annoucement after months rumormill was big surprise at the time since TSMC did massive TW capex expansion and had no $$$ for US fabs, and it was combination of CHIPS carrots ($$$) and US sticks that got Arizona greenlit. Morris Chang publically said CHIPS would fail to get US semi leadership, that US policy is "doomed" / "futile", that is not the words of someone who wanted to erode TW's silicon shield. IMO TSMC Arizona's current (likely ongoing) dependence on imported TW talent makes it pretty clear TW is keeping tight leash.

>Taiwan can't force TSMC

IIRC TW foreign minister said a few years ago it was pure American wishcasting to expect TSMC employees to be evacuated before TW women and children. Around the same time TW politicians rebuffed the idea that TW would destroy their own fabs. That's TW's leverage, they control who gets on and off the planes and boats. Reality is if PRC makes a move, they'll lock down the airfield and shores, that's PRC's leverage - to control if planes and boats get to leave in the first place. Ultimately, TW politicians knows locking semi talent on the island is leverage, especially if they lose, because most of them won't have a ticket off the island.

Not to mention paperclip is the victors getting the spoils, and US is far from assured any victory or there would be any TSMC employees left to paperclip if motivated PRC wants to deny. Or that TSMC is like 70k people excluding their families. 300k if you include other direct TW semi employment. More if you include indirect (supply chain), and ultimately there's considerable sole source semi suppliers on TW that TSMC US won't be functional just like how ASML can shut down hardware by stopping inputs for maintenance. It's not just packaging and domestic talent that's another bottleneck, TSMC Arizona stops with TW inputs as much as it doesn't without ASML ones. And so far there's no real public plan to reshore that supply chain in US.
That's rubbish, it's provable mathematically that given any speed limit it's possible to avoid an overlapping "dilemma zone" that requires speeding up

(v²) / (2a) ≤ (v × t_y) + L

v = vehicle speed (meters per second)

a = comfortable deceleration rate (meters per second squared)

t_y = yellow light duration (seconds)

L = length of the intersection (meters)

You can calculate the minimum yellow time for this using t_y ≥ (v / 2a) - (L / v)

This is rudimentary and doesn't account for reaction time, but a simple buffer would suffice.

The failure is largely in poor planning and poor human behavior.
>Aggressive low performing immigrants from other cultures (Europe)

Elaborate?

https://worldpopulationreview.com/country-rankings/pisa-scor...

USA is 18th and eight of the countries above it are European. The fifteen below it have a comparable score to the USA. That is 23 European countries that are either above or around the same performance (or slightly lower) as the USA. Unless you mean Eastern Europe, which seems like a strange thing to single out
Maybe. I suspect not. There are many ways to game such a system, and I don't believe it will resolve the underlying tensions that I believe are the core threat to democracy, at least in the United States.

(Namely, that we've got a deep antipathy and distrust for one another. Democracy is designed to give us a way to make collective decisions without having to make it personal, but the political is always personal and modern media makes it even more so.)

I'd be willing to give it a try. I think our preset state of affairs is so deeply problematic that pretty much anything different might give us an opportunity to find a better way of approaching each other.

But I believe we won't solve the interpersonal problem with any kind of procedural solution. We don't have to like each other, but we need to establish some minimum level of not actively hating each other, or we'll turn any system to each other's disadvantage.

Shorts is absolute trash. It does not have critical mass and will repeat the same videos to you over and over.

EDIT: I want to overemphasize just how bad it is. It feels like a project someone whipped up in coding bootcamp over a week. It feels like it has zero ability to pick the next video correctly and it genuinely repeats videos between sessions.
The scales get you:

You can’t simulate a molecule at accurate quark/gluon resolution.

The equations aren’t all that complex, but in practice you have to approximate to model the different levels, eg https://www.youtube.com/playlist?list=PLMoTR49uj6ld32zLVWmcG...
I look at the Nix definition for the relevant module as you often need to see what it's actually doing in order to understand it (yes, it's one of those ecosystems).

tiktok is extremely censored re: genocide in xinjiang. facebook is not.
My reading is that the first two CVEs are with rsync daemon, but the others are more general - I think "rsync server" is meaning the remote rsync process that is started when you use ssh to connect to the remote. Some of them suggest the rsync client (running on your machine) can be coerced to write to unexpected locations by a malicious rsync server specifically crafted to exploit these CVEs. One suggests a malicious rsync server might be able to reconstruct the contents of arbitrary files on the client using requests sent via the rsync protocol.

I guess the main takeaway is to be careful using rsync connections to machines that you don't trust.

I'm both glad and dismayed to hear that I'm not the only one who likens public school to prison.

I went to school in California, and I would say my school experience became prison-like between grades 4 and 11. In fairness, I can now look back at my child self and realize that I was delayed in terms of emotional maturity, which contributed to my social problems, but the kind of environment I was in was the wrong one for helping me overcome that delay. Any slight difference about myself, whether it be my body, or my clothes, or my interests, was a target of daily ridicule. The majority of teachers were entirely self serving and didn't give a damn, even when I was being victimized out in the open. Oh yeah, and my property was repeatedly stolen and my belongings destroyed in front of me.

Having gone through all that, there is no way I'm ever putting my future children in such a system.

The way I think about the socialization argument against home schooling is this: Is it better to be highly socialized but traumatized or modestly socialized by not traumatized?

I think it's more valuable for children to be socialized with a smaller number of other children while being in a safe environment. Tossing children into an ocean of other children that is poorly controlled with callous teachers, creating an unsafe environment, has a rapidly diminishing returns on socialization and a greater chance of being counterproductive.

> No one need tiktok.

And we should not underestimate teenagers: if they have something better to do than swiping on TikTok, they do it. Parents must help them have better things to do.

But still, if all their friends know and talk about the TikTok trends, they will feel disconnected if they have no clue. That's how I meant that they "need" it. They need to "connect" as in having the same references as their friends.
yeah, and child labor was not banned, but made mandatory and pointless.
> What is small and what is large is a matter of opinion.

There's certainly there's some vagueness in the middle, for me a few hundred isn't large, but a grand is, and I don't know that everyone would agree, but I think most everyone would agree that $5 is small and $10,000 is large.

No, I do not think China's bugaboos are allowed on TikTok for the exact same reason the US's are not allowed on Facebook
> European internet, American internet, Chinese internet, Russian internet...

Not sure about the European one. Unlike Russia or China, we don't seem capable to produce our own services, or to not use the US ones. Maybe it'll change with the increased hostility of US government and tech CEOs?
In some ways, this is still true, even surrounding this decision.

Do you think there were many people standing outside of government buildings in Beijing protesting the potential ban of Facebook and Google while politicians of different political parties were debating the ban in the country's primary legislative body? Do you think you could launch a campaign for office on repealing said ban in China?
The big issue isn't data security; it's propaganda. Irrespective of whether the government has control of the narrative on Facebook (I would argue they pretty clearly don't) there is no reason to let a foreign adversary have a deniable propaganda line to millions of Americans. Would we have let the USSR acquire a major television network?

And even if you disagree with the national security reasons for disallowing China to control a major U.S. social network, there is still the issue of trade reciprocity - nearly all of the U.S. Web companies are banned in China.
Not disagreeing, that's exactly my point, the govt wants to be able control the narrative
