The west actually had quite some deals with them recently. If not for the trade war there could’ve been a lot more. To some extent it is like the Temu vibe.

There is no careful planning. Just take a look at the waste, the debts and the rapid policy changes. It is more like industrial Darwinism at scale. The main fuel was mainly WTO , export and slavery labor. The industrialization in my opinion is a by product of that process.

China’s success is not because of the policies but rather despite of them. Though not sure how sustainable these successes would be.

I have been wondering if someone could improve golang's cgo infra using clang like what zig is doing..

That was to answer the previous question. Also the point is why Chinese companies can produce infra work in a cheap and fast way. With regard to US companies, I don’t see that is possible with MSFT, AMZN, AAPL, and likely GOOG as well. (Don’t get me wrong, they all have solid infra, probably except Apple)

I would say most if not every large company in China has their own AI infra stack, partially because tech talent is relatively more abundant and partially some of the tech leads have been exposed to western tech via open source and work experience so they have a good success rate (which makes it a more common practice). Anecdotally, specifically Google, FB ex-employees from oversea offices, MSFT and Intel ex-employees from their China offices could be the key elements for this trend in the past two decades (Google left China around 2010).

The infra work is usually technically tedious so I think it may become some lost art in the west just like those manufacturing jobs.

To be blunt this is exactly what is wrong with the “leadership” mindset in the west, as decisions are often made without understanding the “nuances” yet they are confident it would work.

Something definitely doesn’t smell right for Trump/Musk.

Exactly. This is all about power grab without going through a proper due process. The government is shitty and inefficient but DOGE is not the way to fix it.

What DOGE is doing has happened in China 10 years ago. Instead of “fighting corruption” they claim “government efficiency”, but the ultimate goal is to silence and destroy any opposition. Because bureaucracy is inherently universally corrupted, to some extent, and the US has tons of laws at the DOJ’s disposal. That is Xi’s playbook to solidify his power and I am afraid Trump may be using the same one. I certainly hope we won’t be going down that road but to be honest I am not bery optimistic.

It is probably a lot more practical to protect Taiwan than hoping somebody may rebuild Intel for the next 5-10 years. Having TSMC production in US is also more approachable for the mid term.

Forking is not the issue. The real issue is the (mis-)presentation of the additional work and value they bring to the fork. Based on the code commits in the two repos it is minimal if anything at all, while they clearly claimed they have 100 contributors which is totally false.

tway223 — Sun, 05 Nov 2023 17:51:12 +0000

This collection has been on the internet for quite a while, likely started around 2015-ish. It is highly duplicated and I suspect the total number is around 4 million books. Still a lot.

The source was from a company named DuXiu, or previously SuperStar. They collaborated with the libraries around China and scanned their collections since early 2000-ish. Before that I think they just bought some junk books from recycling stations based on the quality of early samples.

Many of the books are translated versions of the textbooks from the west (most likely the US) and many are pure political propaganda junk. Some literature and history stuff which were published when censorship wasn't so extreme.

Many of the Chinese tech companies should have access to this collection (especially Baidu for sure) but the books were not censored based on today's standards so I doubt any of them would openly use them not only due to the copyright issue but also the political risks.

They are records with user info, which are different from user records. Mostly likely just user activities.

Cabinet = jigui in Chinese. It looks like something for operation tracking. Just look at the table names.

To be clear this is not a TikTok ad database. This is a tracking database from a third party who manages their clients' business with TikTok (and others).

2 billion ad views are not that big. You are likely looking at logs not the core tables.

The data could be very likely legit. But they are not TikTok's user database. It is more like TikTok's ad/activity log for some customers. The passwords are for the logins from those customers if any.

This also explains why WeChat data is in the same database. And if you are paying attention, the WeChat tables are more complex which makes sense because WeChat has a much longer history in business.

They are legit. But just not from TikTok. Think of a system where you can manage your ad spending and user growth with TikTok/WeChat (like product promotions, referring from a friend etc.)

tway223 — Sun, 04 Sep 2022 23:21:35 +0000

It is not a TikTok leak. It is more like from a system which is integrated with TikTok/WeChat for marketing / e-commerce usage.

Pretty obvious if you look at the tables closely. And the "cabinet" means hosting cabinets (steel frames holding the machines).

Which means those dudes were basically downloading the ad logs..
