@pretentiouswhat Although the land was acquired through urban expansion, the entire newly added population migrated from other provinces.

@pretentiouswhat Your first point is wrong, so there's no need to even look at the rest.

1000万向量31GB压到4GB，搜索还比FAISS快——这事有点离谱，但turbovec真做到了。核心是Google TurboQuant的数据无关量化，无需训练、不用调参，加向量即索引。手写NEON/AVX-512核实打实快12-20%，支持搜索时按id过滤，直接省掉大量后处理折腾。Rust底层 + pip install即用，维护成本压到极低。 github.com/RyanCodrai/tur…

Updated so different materials/reactions will have different color flames (e.g. chlorine, sodium, potassium, copper). Working on adding more realistic handling of ions soon.

说到vibe coding，使用各种AI工具把代码库搞的又大又复杂，要添加新功能时候真是很无奈，失控到无从下手了已经，全让AI LLM去搞则是漏洞百出，让子弹再飞一会儿吧。

LLM 也写屎山代码，工程复杂度上升之后的必然趋势。

@wey_gu 谢谢回复，但我还是感觉这些都是浮于表面的trick。

@antirez Just say what you think: what do you actually think is good and what isn’t? As the Chinese saying goes: “Don’t take your pants off just to fart.”

Unitree Robotics goes before the STAR Market committee today, on track to become China's first public humanoid robot company. As its first institutional angel investor, it is a good moment for us to revisit the early bet. Jack Zhang, founder of @GeekParkHQ, wrote ~4,000 words on how, in 2018, he wired nearly the entire first fund into @UnitreeRobotics. x.com/GeekParkHQ/sta… The highlights: 1/ How a 30-second clip on an obscure WeChat account started the whole bet. 2/ The first meeting: 3 hours, no deck, no desks, just a hallway couch. (Not even Unitree's!) 3/ Why hydraulics were a dead end for any commercial product, and electric the only road. 4/ How Wang Xingxing rebuilt a top lab's research architecture for under 20,000 RMB on motors he sourced and characterized himself. 5/ "I would not have written the same check for the same founder building the same robot in Palo Alto." 6/ How Unitree's two largest backers today - Lei Jun @Xiaomi and Wang Xing @meituan both met Xingxing in 2017 and passed. (Their stakes today: ~$800M.) 7/ What GeekPark did when the structure broke and Unitree's cash was about to run out. 8/ Why Xingxing bet from day1 that research labs were the right first customer. 9/ What matters to GeekPark more than the Unitree bet itself.

@GillesGressani J'envie sincèrement les Français pour leur confiance en eux, car la confiance en soi est une bonne chose.

@patelnir41 It's a really cool job. You need to build a cognitive framework for agent NPCs. I tried a similar task in Minicrafe last year, and the results were less than satisfactory, but the attempt to internalize agent NPC capabilities is still worth looking forward to.

@EzSpeakMandarin Also in Guangzhou, the sun was beating down when I got on the underground in the morning, but by the time I got off, it was pouring with rain, and I hadn’t brought an umbrella.
