NUMA aware threading is somewhat rare but it does exist.

Its just reaching into the high arts of high-performance that fewer-and-fewer programmers know about. I myself am not an HPC expert, I just like to study this stuff on the side as a hobby.

So NUMA-awareness is when your code knows that &variable1 is located in one physical location, while &variable2 is somewhere else.

This is possible because NUMA-aware allocators (numa_alloc in Linux, VirtualAlloc in Windows) can take parameters that guarantee an allocation within a particular NUMA zone.

Now that you know certain variables are tied together in physical locations, you can also tie threads together with affinity to those same NUMA locations. And with a bit of effort, you can ensure that threads that are in one workpool share the same NUMA zones.

---------

Now code-awareness of shared caches is less common. But following the same models of "abstracted work pools of thread-affinity + NUMA awareness of data", programmers have been able to ensure Zen1 cores to be working together with the same L3 cache.

L2 cache with E-cores is new, but not a new concept in general. (IE: the same mechanisms and abstractions we used for thread-affinity checks on Zen cores sharing L3 cache, or multi-socket CPUs being NUMA Aware... all would still work for L2 cache).

I don't know if the libraries support that. But I bet Intel's library (TBB) and their programmers are working on keeping their abstractions clean and efficient.
This is interesting. I agree, to some extent, but there's nuance in what do you include in the objectification of the concept. The usual argument, as I perceive it, is that we can be objective if we just quantify protocol interference, or DPI, or bogus DNS resolution.

But still, not all blocks are born equal. That's a bit of beating around the bush to avoid going one level up in the abstraction of information controls. There's a thin line between content moderation at the platform level and mandatory hijacking of the DNS system via legal means.

If you squint, they are just a different configuration in the phase space of distributed technical systems, corporations operating in nation-states, and national laws.

Holy shit what a good idea why doesn’t GitHub just let you use ripgrep?!?!?
The best versions of these games are set up to provide more contextual information than just "Player B Died Last Night". Classic Werewolf or Mafia, all information is public information, outside of people just talking to each other in whispers. Among Us adds a map and location information - you have to have been near the person who died to kill them, so if someone died in one room, you suspect players who were near that room or can't account for their location. Clocktower or One Night generally add information that only one player gets, such as being able to know if they're seated next to a bad player, which is powerful, but easy to lie about and risky to just admit since it makes you a target for the bad people.
Is there actually a ban on US social media platforms in China?

Facebook, LinkedIn, Twitter, and others were operating in China, but when China imposed more and more censorship requirements on all social media platforms in China regardless of whether or not they were domestic or foreign and required all of them to turn over user details to the government many chose not to comply, and then China blocked them.

If a US social media platform were willing to implement China's censorship and disclosure requirements for its Chinese operations would they be able to go back? As far as I know we don't know because none of them have tried.

Note that TikTok as we know it is itself not available in China. The original app that became TikTok is in China, but when they wanted to expand to the rest of the world they split it into two companies and the apps diverged. Both companies are owned by ByteDance.

That's probably the approach a US social media company would need to take to try to get back into China.
How could I forget Serokell, too! An Estonian software development firm that uses Haskell and Nix as basic building blocks.

I think they were using Agda or something too for a while, but it appears I can't find what I'm thinking of on their site anymore. Really interesting guys if you're located in the Baltic states.
It's good enough for me on an M1, 16Gb, and slow but good enough as a background job on my older intel mbp with 16Gb. I somehow expected it to not work on intel macs at all, so that's a freebie.
Google also opted to pull out of China instead of selling their Chinese operations to a domestic company. Does it imply that Google had interests beyond financial when operating in China?

I think it's more likely that they don't want the brand name dilution that comes from having a separate TikTok US that's probably going to be a shittier version of the original since it doesn't have the original algorithm (which isn't allowed to be exported) or the original TikTok engineers working on it.
Walked downstairs this morning to my 12 year old girl complaining about the Tik Tok ban and noting that she saw that message. She’s now asking me what Trump can do to save it. It’s going to be hilarious when Trump reverses the ban.
It's a lot less bandwidth to serve one login screen than the entire contents of all of your source repositories to a bunch of crawlers. You can also cache that one login screen in memory.
(Perspective from an American)

Information is the gold of the 21st century. Whoever controls the flow of information has all the wealth and all the power. Therefore, data is the greatest currency in the world.

This outcome was never intended to happen, but ByteDance is taking a chance that the American government will relent. We’ll see in a few months who wins the stalemate.

TikTok has an immense amount of cultural power. The concentration of power scares me, no matter who holds it. But China ultimately having that power scares me more than an American company having it.

Again, this outcome was preventable, but ByteDance is hoping Americans let them continue with the status-quo. We didn’t and we shouldn’t.
Props to you for exploring some ways of mitigating the damage of your hobbies. I prefer EVs despite their increased road wear (at least compared to vehicles that haven't been super sized).

Having driven a lot in my youth, it's just not something I enjoy regardless. I'd rather spend the time and resources on other things. Even taking a longer bike ride to the store is preferred because it's exercise, almost everyone on the trail nods or waves back, and I know my choice is better for everyone in the community.
Google NotebookLM Audio Deep Dive on this HN thread: https://jumpshare.com/v/OFPXiOv9KR8pCtSmWlg2
Classic conflict of interest.

Let’s talk incentives. Pharmacies, insurers, and PBMs (pharmacy benefit managers) are in a tangled drug pricing system. PBMs get rebates from drugmakers for pushing their drugs, but when the PBM and insurer are part of the same company, things get questionable. Suddenly, there’s a clear incentive to favor expensive drugs with bigger rebates, even when cheaper alternatives would work just as well. You’re stuck paying a higher copay and, next year, likely higher premiums too—because, wow, these drugs are pricey! Meanwhile, the insurer isn’t concerned. They’re not covering the full cost of the drug or your copay, and they’re pocketing the rebate. The system works—just not for you.
Oh interesting - thanks for the upload
No Chinese apps should be allowed to operate in USA while similar US apps are banned in China.
Agreed. I would be all in favor of a law that applied to Tiktok, Facebook, X, and all others equally. Singling out Tiktok is just a transparent handout to the US's tech oligarchs, which is worse than doing nothing.
> If China controls the recommendation system that decides what content people consume, then they can influence the narrative of the country.

From Noah Smith:

> Second, the refusal to sell the app tells us that the Chinese government would rather see TikTok destroyed than see it fall into American hands. Notably, that same government put up little fuss back in 2020 when the U.S. forced a Chinese company to sell the gay dating app Grindr to an American company. Why shut down TikTok and leave untold billions of dollars on the table, instead of just selling the thing like Grindr was sold?

> One possibility is that it’s an attempt to make young Americans angry, in the hopes that they’ll demand that Trump and Congress repeal the 2024 law. But a simpler explanation is that Chinese leaders simply think that TikTok, unlike other apps, is so important that they would rather destroy it than see it escape their control.

> Why? Some supporters of the divestiture bill argue that TikTok will transfer Americans’ personal data to the Chinese government — something it has already admitted to doing in a few cases. Others are concerned with TikTok’s social harms. But the biggest concern is that by controlling the TikTok algorithm, the Chinese government might be able to propagandize America’s young people — and to silence Americans who say things it doesn’t like.

> In fact, there’s some pretty strong evidence that TikTok already does exactly this. Rutgers University’s Network Contagion Research Institute has produced a number of papers about TikTok’s manipulation of information to suit Chinese government desires. The standard methodology is to compare topics on TikTok to similar topics on Instagram and YouTube. The NCRI people find that content on the different platforms is broadly similar, except where China-related issues are concerned. […]

> > China doesn’t allow US social media companies to operate there.
> This statement is not entirely accurate. It is possible for a US social media company to operate in mainland China, provided it complies with local regulations, including hosting its servers in China and adhering to censorship requirements.

OminiControl is a web platform that lets users upload an image, select a specific area, and modify it using AI by entering a prompt. For example, you can upload an image of the Statue of Liberty, select the torch, and turn it into something else, like an ice cream cone. It offers endless creative possibilities for image editing.
Oh interesting - thanks for the upload. Ahh - its the N/A political diversity being seen as 'low' when a null should just have no impact on score.

Thanks! Will work on a fix
Many people identify themselves with being "a coder". Surely there are jobs for "coders" and will be in the future too. But not everyone writing programs today would qualify to doing the work defined as what "a coder" does.

I like to be a "builder of systems" , "solver of problems". "Organizer or manager" would also fit in that description. And then what tool you use to get stuff done is not relevant.

This is by design. Anti-cheat solutions are intended to be opaque. This also applies to bans from many online platforms.

This needs to change, because their systems are not 100% accurate. They need to be able to prove that you cheated or broke ToS before they can ban you and effectively steal any money you've paid them.

Let’s not forget that Hunter Biden is an adult man with free will and did in fact commit crimes. It might be sensible to pardon, but that outcome is opposite of what the president said he would do. It’s okay to point that out.

Not familiar with that. Could you elaborate?

It seems to imply he’s not the only one who’s done something like that. In that case, I totally agree, political figures are masters of political posturing and taking credit

We all know that G.W. Bush and Tony Blair were at the top of their countries' chains of command during the illegal invasion of Iraq and yet, here we are, they're free of any International Penal Court meddling. Which is to say that maybe these guys and ladies here should focus their "desire for war-justice" a little bit closer to home.

Of course, an organization (the Security Force Monitor mentioned in the article) that literally receives money from George Soros through his Open Society Foundations [1] would never go after its own Western leaders, but it's good to at least have that written down on the internet, like in this comment.

Show HN: Minimalistic Hashi Bridges
As a part of our computer vision lab, we're trying to understand optimal pathfinding solutions in confined lattices, where we came across the game of Hashi.

Here is the online version that I built, go give it a try! I'd love to hear your feedback!
Oh sweetheart. Just search twitter for “jews”.
I hate to say it, but I understand this. I really tried to implement matrix in gov, but the only way to convince decision makers to use it rather than slack was "it's free if we just use the non pro stuff".
So, I guess China had it right with its great firewall then, right? I mean you have to protect your national interest against foreign corporations. I didn't know Americans would agree with CCP policies like this.
I've been working on code-push-cloudflare-workers, a serverless alternative to CodePush built on Cloudflare Workers. Unlike the official CodePush server, which requires Azure infrastructure and comes with ongoing costs, this version is fully serverless and operates within Cloudflare's free tier—making it nearly zero-cost.
> Nope. That's precisely wrong. Tl;dr heating normally uses less efficient technology than cooling and has to work across a higher temperature difference.

That’s moving the goal posts. You can always use a heatpump to heat a space.

Any space you want to keep comfortable will always be easier if the outside is cooler than your target temperature. Everything in that space is going to produce heat as a natural consequence of expending energy into any form. It’s always possible to add insulation to minimise the amount of energy you loose into the surrounding environment, and you can always modulate how much additional energy you let escape using a simple opening in that insulation.

On the other hand, if the external space is hotter, then you must always expend additional energy to move waste heat energy accumulating in the space into the high energy space outside. There is no passive manner that can allow you to cool a space surrounded by a hotter space, you’re always fighting against the temperature gradient. And if you want your living, heat producing, organisms to keep living, then you need to get rid of the heat they produce.
But not certificates of credit. So you could store money, but you could not deposit it and then get fungible currency from other bank.
Marvel Snap down, caught in the TikTok ban
If China doesn’t permit our social media and search engine companies to operate in their country, why should we allow theirs in ours? Reciprocity in market access should be a baseline expectation.
Sounds great to me. Now EU authorities should ban Xitter in the EU. Stop foreign election interference!
The TikTok branding and user base are already firewalled from ByteDance's Chinese operations.

Their Chinese variant of TikTok is called Douyin, so there wouldn't be any brand dilution from spinning TikTok off.

I also have doubts that the technology behind TikTok would be difficult for a western engineer to understand. It's a relatively straigtforward algorithm, and it's details have been shared in a public paper.

> It's the opposite: if they can block any alternative to the "hive mind" they can easily pursue any interest they like and make you believe that they align with your interests.

It is definitely not the opposite. You have very recent cases where Russia has been caught financing US right-wing hate-speech "influencers" to spread extremist talking points fed by Russia's propaganda effort. Their purpose is to sow divisiveness and turn Americans on each other.

https://www.washingtonpost.com/technology/2024/10/01/russia-...

It was not the first time either. In 2016 Russia was caught actively trying to spark a race war in the US.

If the US was doing this for teen mental health, they'd have banned Twitter and Facebook too.

This isn't about teen mental health.
Because it will not happen. And cannot be enforced.

No, im not arguing this because US already uses more propaganda than China. I was asking why americans are so afraid that chinese propaganda will be so more powerful than the Inês that they already have.

The US could have just built a regulator and laws like we have for alcohol and drugs. It's not difficult. But banning the creepy Chinese thing is far easier.
> In the meantime, alternative Chinese-owned apps like RedNote and Lemon8 have received a boost as TikTok users search for alternatives.

Why does it seem that there's no non-Chinese alternative to TikTok popular enough to warrant any mention?
The votes are following the propaganda, and Trump won the public opinion war. Democrats have been slow to learn this lesson and get their messaging and public relations under control.
Why is China your enemy? China couldn’t care less about the US. They’re doing their thing now, and they’ll keep doing their thing when China overtakes the US as the top global power.

Why are you so afraid of China?

Do you think there will be a war with the US? I find that extremely unlikely given both nations have atomic bombs and nothing to gain from war.

Do you think the US is gonna get economically bullied by China? Well, that’s what the US does to the rest of the world right now. Ironically, that’s why most of Africa would rather partner with China for economic development than with the western powers. But even then, the US is big enough that it can insulate itself from most of that.

Are you afraid that China will start a war in Taiwan? They might, but didn’t the US start a war in Iraq as recently as 20 years ago. Not to mention all of the other middle east conflicts the US is involved in.

You can’t stop China. They have 4x as many people as the US, and just as big a landmass with plenty of resources. China will become the top global power. But that doesn’t mean that your life will be any worse.

It means that your politicians won’t be able to act with impunity as they have for the past century. It means your billionaires will have to compete with China’s billionaires for investment. It means companies will have more competition.

But at the end of the day, your life won’t change. It will probably get better if we’re being honest. China is not your enemy.
The author quotes Google vs Oracle where the case was about using headers for compatibility: IIRC to provide an alternative implementation.

This is different from vv which uses the headers to link to the GPLed code.

IN most jurisdictions the GPL is a license, not a contract, and is definitely designed not to be a contract.

That said, as far as I can see vv is in breach of the GPL. This is a case of someone who wants there to be a loophole convincing themselves there is one.

I would definitely not redistribute vv because of that. More importantly I think it likely that people packaging software for Linux repos are not going to want to take the risk, and many will object to trying to find a loophole in GPL on principle too.
Sure, find, cat and split would do the job.
I'm not gonna put a dissertation in a HN comment. I wouldn't have to if more people practiced steelmanning.
>which obviously fall out of scope of the First Amendment.

It obviously doesn't. That would mean the US Government can ban all foreign press, just by designating countries as "foreign adversaries". And "foreign adversaries" is a euphemism for "countries that don't submit". The SCOTUS just invented another exception to the absolutist interpretation.

>wholly uncontroversial indictments of the owners of Tenet Media

>were charged with failing to register as a foreign agent

This entire narrative together with the banning of Tiktok is wholly hypocritical, given the American media, tech, and NGO's influence/dominance around the world.

The moment someone achieved what the American entities have been doing around the world, the non-stop wailing of "foreign adversaries this, foreign adversaries that" started.

Meanwhile in Georgia, a country bordering Russia, the law requiring foreign-financed NGOs to register was declared to "stigmatize organizations that serve the citizens of Georgia" with accompanying travel bans for the authoritarian evil doers who passed said law by the US state department.
Models don’t know their own weights, so I’m not sure what this means.
No, primarily Mark Zuckerberg and Elon Musk, and other big tech execs to a lesser extent.
More importantly, does it work on forwarded marketing spam, and what is your e-mail I can forward my spam to? :)
I didn't say it was. It was meant to refute the claim that you can't have an organized society without banking.
That it's unreasonable to expect users to mitigate this by hunting around others' profiles for snippets of conversation is my opinion, yes.

That one user blocking another user makes chunks of the conversation disappear for everyone else viewing the thread is verifiable fact. As it is a verifiable fact that this is done server-side via the getPostThread endpoint, by which posts in the parent and replies fields of the response are omitted.

This is not "absolutely and provably wrong", as you put it. Maybe do some research yourself before accusing others of intentionally spreading falsehoods?
I'm an American too, and I trust an app that has "china" somewhere in it's org chart more than Zuckerberg or any meta product.
