maybe on the right path?

the cost of re-industrialization anyway?

model train network?! a network to train your large language model?

Curious if we say "thank you", the model will be more activated and result in better answer. ^^

qtwhat — Thu, 15 May 2025 11:51:00 +0000

DeepSeek-V3 demonstrates that thoughtful hardware-software co-design can overcome the scaling challenges of large language models. By integrating innovations like Multi-head Latent Attention (MLA), Mixture of Experts (MoE) architectures, FP8 mixed-precision training, and a Multi-Plane Network Topology, DeepSeek-V3 achieves cost-effective training and inference at scale. This paper delves into these advancements and discusses future directions for AI hardware and architecture co-design.

no one mentions market manipulation?

Is this saying, we can use LLM to understand non-language signal? Sounds fun!

The world is a much better place with a saint like you.

New comment by qtwhat in "China's total wind and solar capacity outstrips coal"

qtwhat — Mon, 12 Aug 2024 02:38:40 +0000

or did you even read? the latest data shows:

"Coal power additions were about 40 GW in 2023, while the first half of 2024 saw only 8 GW of new coal capacity, according to Rystad Energy’s estimates."

the additions is significantly lower in 2024, and the trend is showing a decreasing, dramatically.

also, any country does not seek political influence is non-sense. then what is your point?

very clever idea!

if you know how OTDR works, location is known by high speed modulation and high speed sampling components, which means high costs, if you want to achieve higher resolution. Usually the laser pusle will be in the level of nano seconds.

what's being introduced in the article is using multiple fibers with coded location info. therefore no need to have sophisticated OTDRA-like equipment to get the location info.

not sure if my understanding is right, but good job: from a simple idea to sophisticated design, optimization and even commercialization.congrats.

In China it is about SA only now, maybe since 2022 if I remember it correctly, all cell phone that support SA can only be allowed to enter the market. and all base station shall support SA too.

This is journalist or journalism of our mordern world.

What is "sought hospital care"? To get some Vitamin C or get some serious surgery? (In China people go to hospital more often I guess, as people tend to deal with ailments relying on doctors a lot, rather than letting it go by itself.)

Nothing told.

True. But note that in 3G and 4G period, there are a number of systems that are not compatible to each other, like UMTS vs CDMA, LTE vs WiMAX, while 5G is the global one.

This answer and the answers below ignored one simple point: 5G is a global collaboration (3GPP), not a regional experiment, which includes operators around the world and vendor around the world (not true, few from American..). You can basically call 3GPP the dictatorial organization, simply it is the only organization truely working on the cellular technique.

More importantly, it is getting stronger, and the ecosystem getting more diversified as more OTT and devices vendors like Google, Tencent, Alibaba, Apple, all joining in.

Face it, US is being left behind.

To the opposite, the west provides a buffer region where people with insights can swing in between. Also, universities in China are way behind compared to western ones, but the later ones also serve Chinese students well. Such system benefits all.

so US citizens are superior than Chinese or people elsewhere around the world? why is no one mentioning human rights now?
