Former GM Executive: BYD cars are good in terms of design, features, price, quality. If we let BYD into the U.S. market, it could end up destroying american manufacturers by BB84 in c/[email protected]

If something is being so heavily subsidized, the correct market response is to buy as much as possible, and resell once the prices ramp up.

Setting up tariffs and complaining about subsidies? 100% not the "free market" response. It's cope.

No. Multipolar means everyone can have multiple independently powerful allies/enemies. It means India, ASEAN, etc. being powerful enough to step in and help ROC when westerners decide to abandon it.

There are a lot of protests in Hong Kong, but the Hong Kong protests was definitely after 2015.

Trade worth considering for Europe. Huh. So fuck the Taiwanese, if that's good for Europe?

This kind of thinking by Westerners is why "multipolar world" as a concept is so popular.

James Webb confirms something is deeply wrong with how we understand the universe by BB84 in c/[email protected]
[-] [email protected] 94 points 3 months ago* (last edited 3 months ago)

The article over-dramatizes the story. This "deeply wrong" discrepancy is less than 10%. CMB measurements predict a Hubble constant of around 68km/s/Mpc. Distance ladder measurements get around 73km/s/Mpc.

Our current understanding of the universe the Lambda-CDM model is still wildly successful and it's more likely that the true correct model of the universe will be a correction/extension to Lambda-CDM rather than a completely new theory (although if it is a completely new theory that would be pretty cool).

A microblog post by @kareem_carr saying "as soon as i saw they were using asterisks for multiplication symbols, i knew we were in trouble", with an image from the "Office of the United States Trade Representative (Executive Office of the President)" showing the mathematical formula $\Delta \tau_i = \frac{x_i - m_i}{\varepsilon * \varphi * m_i}$. The formula show asterisks (*) instead of multiplication signs (×).

New Nasa data hints we could be living inside a black hole by BB84 in c/[email protected]
[-] [email protected] 55 points 3 months ago

I recommend critically reading the paper. It is quite accessible to those with college-level science background.

Most importantly, it is still highly controversial whether this galaxy rotation direction bias actually exists. If you look at section 4 of the paper, the author is debating against different groups that did similar surveys and found no bias. Someone needs to actually work through this author's methodology as well as those of other groups and figure out what is going on.

If there is indeed a bias, that is super exciting! An anisotropic universe due to being in a black hole would be a very cool explanation. But given the ongoing debate, a general-audience publication like Independent presenting this rotation bias as a given fact is very poor journalism.

Did I say OC? I photoshopped the Bloomberg thing on top of someone else's meme that I ~~stole~~ obtained via fair use. It's basically OC by tech companies' standards.

Caption: an interview dialogue

  • Are dark matter models unsuited to explain observations? [the "dark matter models" and "to explain observations" parts are poorly edited onto the image, overlaying the original text]
  • In my view, they are unsuited.
  • Why?
  • That's my opinion, don't ask me why.

End of caption

Dark matter is the mainstream among physicists, but internet commentators keep saying it can't be right because it "feels off".

Of course, skepticism is good for science! You just need to justify it more than saying the mainstream "feels off".

For people who prefer alternative explanations over dark matter for non-vibe-based reasons, I would love to hear your thoughts! Leave a comment!

OpenAI announces plan to transform into a for-profit company by BB84 in c/[email protected]

Stop depending on these proprietary LLMs. Go to [email protected].

There are open-source LLMs you can run on your own computer if you have a powerful GPU. Models like OLMo and Falcon are made by true non-profits and universities, and they reach GPT-3.5 level of capability.

There are also open-weight models that you can run locally and fine-tune to your liking (although these don’t have open-source training data or code). The best of these (Alibaba’s Qwen, Meta’s llama, Mistral, Deepseek, etc.) match and sometimes exceed GPT 4o capabilities.

New open-weight 🐋 DeepSeek V3. 685B MoE. Beats Claude 3.5 Sonnet on Aider coding benchmark (huggingface.co)

Absolutely humongous model. Mixture of 256 experts with 8 activated each time.

Aider leaderboard: The only model above 🐋 v3 here is ~~Open~~AI o1. DeepSeek is known to make amazing models and Aider rotates their benchmark over time, so it is unlikely that this is a train-on-benchmark situation.

Some more benchmarks: on Reddit.

Yes, the earth accelerates toward the ball faster than it does toward the feather.

Tap for spoilerThe bowling ball isn’t falling to the earth faster. The higher perceived acceleration is due to the earth falling toward the bowling ball.

The x axis is position. The y axis is energy. The blue box is a potential energy barrier. The red curve shows the wavefunction of a particle at a certain energy level coming in and tunneling through the wall. (the wavefunction actually live on a different y-scale from this plot and is only superimposed here for illustrative purpose, so don’t use the energy y-scale to read into the amplitude of the oscillatory part).
