Whenever I see topics about China on HN, I get this strong sense of unease. The reality is that most people don't actually understand China; when they think of it, they just imagine a country where 'people work like expressionless machines under the CCP’s high-pressure rule.' In truth, a nation of 1.4 billion is far more diverse than people imagine, and the public discourse and civic consciousness here are much more complex. Chinese people aren't 'brainwashed'; they’ve simply accepted a different political system—one that certainly has its share of problems, but also its benefits. But that’s not the whole story. You shouldn't try to link every single topic back to the political system. Look at the other, more interesting things going on.

Every now and then, news like this pops up and sparks some discussion. But in reality, I believe any internet-based business—every single app to some extent—tracks users in this way. It’s just the nature of the internet.

I keep seeing people talk a lot about edge AI — just curious, aside from those experimental or toy projects, are there any real killer use cases out there?

I believe that ‘cloud-neutral’ companies like Wiz must ensure their neutral positioning in order to gain support from various cloud providers. I strongly doubt the willingness of cloud providers like AWS and Azure to cooperate in the future. Google is not only making a major business gamble but also testing the waters in terms of antitrust and judicial challenges.

I would like to ask, what practical uses do similar data have in production scenarios? For example, to count the density of a crowd? Verify the authenticity of a company or for other purposes?

And these restrictions only exist in online games. In fact, there are no restrictions for single-player games and console games.

New comment by dingody in "The six dumbest ideas in computer security (2005)"

dingody — Mon, 15 Jul 2024 03:10:09 +0000

I don’t entirely agree with the author’s viewpoint on “Hacking is Cool.” There was a time when I thought similarly, believing that “finding some system vulnerabilities is just like helping those system programmers find bugs, and I can never be better than those programmers.” However, I gradually rejected this idea. The appeal of cybersecurity lies in its “breadth” rather than its “depth.” In a specific area, a hacker might never be as proficient as a programmer, but hackers often possess a broad knowledge base across various fields.

A web security researcher might simultaneously discover vulnerabilities in “PHP, JSP, Servlet, ASP.NET, IIS, and Tomcat.” A binary researcher might have knowledge of “Windows, Android, and iOS.” A network protocol researcher might be well-versed in “TCP/IP, HTTP, and FTP” protocols. More likely, a hacker often masters all these basic knowledge areas.

So, what I want to say is that the key is not the technology itself, nor the nitty-gritty of offense and defense in some vulnerabilities, but rather the ability to use the wide range of knowledge and the hacker’s reverse thinking to challenge seemingly sound systems. This is what our society needs and it is immensely enjoyable.

I heard that GPS is one of the few applications in daily life that needs to consider relativistic effects. So, the generated data must have already excluded these relativistic effects, right?
