feelingsoniceon Launch HN: EdotEnv (YC S26) – Quant Trading RL Envs to Teach LLMs Research

Is it STRICTLY for LLMs & quant research or does it do generic trading simulation?

feelingsoniceon Launch HN: EdotEnv (YC S26) – Quant Trading RL Envs to Teach LLMs Research

I'm not fully clear on this. Is this a quant trading benchmark for LLMs or a RL env?

feelingsoniceon Boarding China's Last Bus

What evidence are there that this statistical gap in AI enthusiasm shouldn't be interpreted as is? What if China IS just more enthusiastic about AI? It sounds like the author pointed out differences in surveyed enthusiasm, and then basically said "well this can't be real."

feelingsoniceon The Annotated JEPA

No AdaJEPA is a deployment-time mechanism, it's not about building JEPA at all

feelingsoniceon The Annotated JEPA

Okay I see it now, but it's briefly mentioned without describing the mechanism. The author didn't annotate it the same way they annotated JEPA. I feel like LeJEPA should take precedence in the article since it supersedes JEPA.

feelingsoniceon The Annotated JEPA

LeCun's new paper takes a new approach to building JEPA, which he named LeJEPA -- https://arxiv.org/abs/2511.08544 It's not that different in the underlying theory but he removes the EMA and the twin tower, makes the whole thing more straightforward.

feelingsoniceon Green card seekers must leave U.S. to apply, Trump administration says

Because coming to the United States on a non-immigrant visa is pretty much the only way that a person can hope to become a US citizen (or green card holder) eventually.

Maybe you can use that^ to snap the pixels to a perfect grid

feelingsoniceon GPT-5

I have the pro plan but don't seem to have access to it?

feelingsoniceon Gemini-2.5-pro-preview-06-05

I'm confused by the naming. It advertises itself as "Thinking" so is this the release of the new "Deep Think" model or not?

feelingsoniceon European Investment Bank to inject €70B in European tech

What does “inject” mean here? Iirc, Israel did something similar a while back and boosted a ton of startup early on, but they quickly died off and they realized you need the scrutiny from free market VCs to create competition.

for a lot of startups

feelingsoniceon OpenAI o3 and o4-mini

I’m having very mixed feelings about it. I’m using o3 to help me parse and understand a book about statistics and ML, it’s very dense in math.

On one hand the answers became a lot more comprehensive and deep. It’s now able to give me very advanced explanations.

On the other hand, it started overloading the answers with information. Entire concepts became single sentence summaries. Complex topics and theorems became acronyms. In a way I’m feeling overwhelmed by the information it’s now throwing at me. I can’t tell if it’s actually smarter or just too complicated for me to understand.

feelingsoniceon GPT-4.1 in the API

Does this mean that the o1 and o3-mini models are also using 4.1 as the base now?

Why won't they add benchmarks against o1?

feelingsoniceon DeepSeek releases Janus Pro, a text-to-image generator [pdf]

But it sounds like, from that quoted statement, that LeCun from Meta thinks “open sourced work” is why China was able to surpass (or at least compete with) American AIs. Which sounds like a lame excuse for Meta.

feelingsoniceon DeepSeek releases Janus Pro, a text-to-image generator [pdf]

I don’t buy this at all. If DeepSeek can surpass proprietary models by “profiting” from open research and open source, why couldn’t the proprietary models do the same? Companies making proprietary models have the advantage of using w/e is out there from the open source community AND the proprietary research they have been working on for years.

feelingsoniceon Rewriting Rust

>And I don't know if it will ever be there. Progress on the language has slowed so much. When I first started using it, every release seemed to add new, great features in stable rust. Now? Crickets.

Is frustration with Rust on the rise? I just started using Rust few month ago and absolutely love it. I can't tell what's going on with the Rust foundation so I can only judge by reading sentiments. Nothing would kill my vibe harder than knowing smart people thinks the language isn't doing great :(

feelingsoniceon Swift 6

Swift needs to figure out what it wants to do and stick to it. Too many syntactic sugar and too many half baked concepts pushed through the door.

feelingsoniceon There's No Good Reason to Trust Blockchain Technology

"Private blockchains are completely uninteresting. (By this, I mean systems that use the blockchain data structure but don’t have the above three elements.) ... Consensus protocols have been studied in distributed systems for more than 60 years. Append-only data structures have been similarly well covered."

I don't entire agree with this. Yes, distributed systems and various consensus protocols have been studied for many years, but the cryptocurrency boom boosted public interest and applicational development in a way that would not have happened without it.

Private blockchain can have many benefits compared to centralized models. It's not necessarily better and it's more of a trade-off, but it does present solutions that's not otherwise possible. For example, in a distributed system, we can use IoT devices as lightweight nodes for quick validations. This can give security to off-site locations with limited computation power and/or connectivity.

In addition, there's now many consensus protocols that tries to solve or amend the three elements the author mentioned. For example, Stellar-Lumen's implementation of Federated Byzantine Agreement creates the concept of reputation on top of trust. The ledger network is public, and is essentially a directed graph of trusts. Anyone can join but other nodes pre-existing on the network may not necessarily trust your validations, so this at least amends the first element the author mentioned.

In conclusion, blockchain technologies are over quoted for their finance applications. To quote a YouTube video I watched, look at blockchain technologies as the operating system, and cryptocurrency as one particular app on the operating system, like your browser. It surely is over hyped but shouldn't be hated upon solely due to the public's mistaking interest.
