Ben Horowitz in THE HARD THING ABOUT HARD THINGS mentioned similar thing:

> China has taken all the benefits

I thought Trumpism is not welcome here?

> Globalization will live on, but only for countries who align themselves with the west.

So globalization is just westernization?

Yeah, and you wonder why paying money to the descendent people raped/killed/mutilated/{and many other horrendous anti-human barbarism brutality} [0] is not enough to get peace.

Turns out, people are not stupid.

If the wrongdoers are not sincere, money never suffices. For example, you'll need a court to uphold an apology [1], then what is the substance of the apology anyway?

> The third link is also from a heavily biased source.

The link referred to: https://koreajoongangdaily.joins.com/news/article/article.as...

Wow, "biased source", what a word!

I think aside from the universal "China is bad" theme, the other theme closely related in Asian political discussion in HN, is that "Japan already did her part for their WWII and imperialism war crimes"...

Unfortunately, no.

Japan has never addressed the issue with any nations that they invaded in WWII. Literally, each and every suffered from Japanese imperialism invasion still have deep and broad hostility towards Japan whenever the topic start to divert to WWII and the era.

I have no idea was it Japan government intentionally doing this inadequate job, or are they simply incompetent on this matter.

But to call this website "heavily biased"... Bravo, this is borderline racism towards the people living in the nations suffered from Japanese invasions.

> and the reason the govt doesn't do anything about it despite flooding being a major political issue is corruption

Could you provide evidences of governmental corruption that actually result into this?

Something like: * A given amount of budget were allocated to hire public sector workers to do necessary management work (coordinating, communication, planning of non-flood-hazard residential zones etc.)

* A proof that the above budget meets the required efforts

* Evidences that the people are cooperating with the government, if the government actually carried out such campaingh.

Corruption is everywhere. In the sense that individuals not doing what they suppose because of selfish motivations.

But to blame a government on systematic corruption, there has to be evidences that resources are available, but the government choose to neglect.

The liberal fantasy that "eliminating corruption, then your imagination will become reality" does not exist in reality at all.

> the theft of trillions in IP

This is just pure propaganda. If one can accurately count for the IP theft and come up with a value number. And argue that it's trillions theft from the US business man, without those business man not refarining from doing business in China, then the basic profit-seeking behavior is not working in the US China bilateral business dealing.

You can claim that US businesses lost trilliones which are larger than the profit they collected, and assume that the business men are stupid and not knowing the value of their IP.

That's just senseless argument.

> the theft of trillions in IP over decades as "some online hacking".

Online hacking is very small part from China. And they are usually backed be global hackers from compromised hosts located in Chinese territory.

If you watch old movie, you start to understand the modern CGI produced movies are having a problem of the movie makers cannot decide what they want to tell the audience, and they start to throwing as much staff on screen and hope they can appeal to most of the people.

In addition to the splash of pixels and colors, the dialogue is hard to follow in modern films, google "modern film voice is hard to hear" you'll see that's a common complaint.

https://www.reddit.com/r/movies/comments/a723x7/do_you_find_...

The last batch of movies that do not suffer these are LOTR trilogy, and the matrix (not the sequels). Then from then, I cannot recall any film that has a clear idea and is keen to focus on the idea and develop the film accordingly.

A significant recognition of eBPF's potential.

This is a followup of an earlier paper at HostOS 21 (https://sigops.org/s/conferences/hotos/2021/#program), by the same research group. Previous discussion on the earlier paper: https://news.ycombinator.com/item?id=26601841

Prior to this work, eBPF is mostly used for networking and kernel tracing.

Networking has a very rigid framework, and eBPF is mainly doing things that can be done in old techs (DPDK etc), but is supposedly better. But that might be always clear-cut superiority, a recent discussion https://news.ycombinator.com/item?id=31982026 shows the claimed superiority of DPDK comes with a lot of caveats.

Kernel tracing with eBPF is mainly for observability purpose. It's very useful. But has not been able to bring business value directly to software users.

Now with XRP, eBPF offered, for the first time, unprecedented and novel capability for accelerating IOs circumvent the existing Kernel + userspace separation.

I am very keen on the development of this area.

Then there are a lot of Chinese companies are banned from US market.

I guess you are probably forgot what NSA did to your phone calls?

That has not weaken their legitimacy as the government agency, or US government's legitimacy over US citizens.

Equating some online hacking with punching in the face, is probably as convincing as Trump stating Kungflu with Covid.

Great

EV boom will propel the battery manufacturer to be the next manufacturing Behemoth. It's so much a core of any EV that the industry capital has to be consolidated to be able to produce sufficiently good product and iterate rapidly to match the market demand.

My bet is on CTAL though. Not Volkswagen

> I remain convinced that "real" self driving (as in: go ahead and sleep in the backseat) will never happen without changes to road infrastructure and possibly some sort of segregation between robot-driven cars and people-driven cars.

Yep, I talk to people working in traffic engineering, and their mindset is always building new road tech and road-side and cloud infra to support autonomous driving. They have no expectation of fully autonomous vehicle without road and infrastructure assistance.

And from historical perspective, the coming of automotive and the replacement of horse and other animal carts, are exactly facilitated by the road transformation; which has been the single largest scale infrastructure in human history.

It makes no sense that an even bigger transformation of the vehicle would require less drastic road transformation.

They are similar in that there are laws reconigized domestically and internationally to block Texas and Taiwan from becoming independent from their home country.

Hah?

A US companies' internal employees were conflated to China? And who the hell allows TikTok to operate in US in the first place. If someone working at MSFT has access to MSFT's China user data, is that a problem?
throwaway123989

None of these are banned. They simply choose to not operate in China, because the laws require them hand over user data. So they choose to monopolize those data themselves, which is allowed in US and so called "free" nations. Go figure how ridiculous that is.

Why is China an adversary of US?

Can someone put into succinct evidences of this statement?

To the typical talking point:

* IP infringement: there is not much unusual rate of IP stealing from China. Considering the size of Chinese economy and foreign trade ties between China and the rest of world, absolute number of IP infringement cases are not a good indicator of the government's policy.

* Coercion of South East Asian nations: This one is a natural demand of a rising super power. Putting it in the perspective of any historical rising of superpower, China has been relatively much more peaceful. Again, the sheer size of China make the absolute number terrifying, but please stay rationale, and don't try to paint China as some sort of arch evil of the west Civilization. After all, the West has been nourished by the Oriental civilization, among them China particularly contributed to the advancement of knowledge and inventions (gun powder, magnet etc.).

* Confrontation with US over Taiwan: If you are OK with Texas leaving the union, then you are entitled to support Taiwan independence. Enough said. Pick your side, and stick with it.

PS: I am Chinese living in US. And I support the peaceful cooperation between China and US. The 2 nations are the most refined examples of the oriental and western civilizations. It's indeed a tragedy that the finest human civilizations cannot work together. We Chinese living in US, as well as the US people having good exposure in China, are in a good position to amplify the cooperative ties between China and US.
