So many fellow Chinese are obsessed with marshal parades. Well, they just shows. We really need to demystify politics and militaries. They are just organizers of expensive shows that everyone pays for.

"AI can only write simple SHELL scripts" -> "Well, AI seems good at handling Database schemas" -> "Oh, AI is good at Python, but that's still scripting" -> "What? AI can make frontend interfaces" -> "Damn, AI can write good Golang backend" -> "But C++ is too complex for AI I…

Debugging the front-end is way mucher harder than debugging the backend. You have to trace from UX/UI to components to modules to logics to codes. What's worse, the performance issues reported by browser usually are even more difficult to debug and fix.

On this platform, retweeting with a screenshot of the quoted tweet rather that directly quoting the original tweet is super guilty. It is the source of misinformation because screenshots can be made up maliciously. It's a shame, never do that, and never trust screenshots.

AI is not killing coding. AI has killed coding training. Anyone still paying for online programming courses?

Do you usually use "friend" in C++ (friend functions/classes)? Apparently, it violates encapsulation, isolation, and interface-first OOP principles. The "friend" mechanism to C++ is just like "goto" to C - useful but fundamentally bad. Friendship in Programming is a bad idea.

No, using raw pointers in C++ in 2025 means you are writing C, not C++, of course not modern C++. Use STL or equivalent Template Libraries. They are encapsulated enough to avoid any necessity of raw pointers.

We've developed CPU from 32 to 64, yet we still cannot shift the GB from 1,000,000,000 Bytes to the precise value: 1,073,741,824 Bytes. We still have to use GiB, in serious scenarios. We are so smart.

You can play with dynamic data structures in C, but there is one rule: Do not assert memory allocation succeeds, instead, always check NULL return.

You would definitely be doomed if you really, really think that AI is smart enough, vibe coding is reliable, and your computer is secure with LLM:

If you are obsessed to AI in your phone, I'd say, good luck to your privacy. I like AI, but take over my phone? Get the fk outta here.

Just curious but isn't OAuth a debatable decision for your apps? Your user statistics (not the data in your app but the signup/signin) would be exposed to the OAuth providers, right?
