fcanesin··on InventWood is about to mass-produce wood that's stronger than steel
Does anyone know if extensive genetic editing for construction wood optimization has been tried? Some planted forests have no food chain role whatsoever (like Eucalyptus in Brazil) so this seems super safe high reward endeavor.
fcanesin··on OpenAI reaches agreement to buy Windsurf for $3B
LMAO, like one hour after. And guess what, it is a coding upgrade .
fcanesin··on OpenAI reaches agreement to buy Windsurf for $3B
OpenAI knows that everyday someone uses Gemini their ChatGPT brand dies a bit faster. Wonder what Google has in storage for I/O now in May, would be a death sentence to just steamroll with Gemini-3.
fcanesin··on PSA: Get Flash Attention v2 on AMD 7900 (gfx1100)
Sharing here because it was really hard to dig this from issues on GitHub instead of official documentation...

fcanesin··on Nvidia’s $589B DeepSeek rout
Certainly one of the most valuable, but I would still say TSMC as there are lots of other steps in the production besides photolithography (etching, ion implantation, vapor deposition, packing, ...).
fcanesin··on Nvidia’s $589B DeepSeek rout
Nvidia doesn't have a monopoly on GEMM and GEMV. There will be dozens of hardware vendors. It is TSMC that should be the most valuable company in the world.
fcanesin··on Former President Trump has won the presidency

fcanesin··on Trump wins presidency for second time
AtlasIntel did. I met Thiago (CTO) in Rio and Boston while he was doing his math PhD at Harvard, he is nice person and a fine mathematician: their methodology uses online polling on social media with micro-targeting. I only assume competitors are not leveraging social media as well as they are. Roman, the CEO, said they will donate all their raw data from the final polls to Roper Center at Cornell for academic research[1].

fcanesin··on Sqlite3 WebAssembly
Isn't a more advanced/production version of this what the combo of couchdb and pouchdb do since several years ago?
fcanesin··on Brazil data regulator bans Meta from mining data to train AI models
Meta updated its Privacy Policy on June 26, to include in its rights the use of data collected in "Meta Products" for the training of GenAI models. This goes against the interpretation of the local data protection law and as such this note was emitted.

The policy update seems to be global: https://www.facebook.com/privacy/policy

fcanesin··on Micron Kicks Off Production of HBM3E Memory
By the article (March production) new GPU eng. samples should be flying in H1 which means new high memory GPUs coming end of the year. 2025 will be extremely exciting for ML.
fcanesin··on China is building nuclear reactors faster than any other country
I believe it is also building dams, ports, bridges, tunnels, metro lines, high-speed trains and highways faster than any other country.

fcanesin··on AMD Ryzen APU turned into a 16GB VRAM GPU and it can run Stable Diffusion
This reminds me of Radeon Pro SSG. A 2017 GPU with four ssd slots and 16GB of HBM, maybe now with nvme PCIe 5.0 ssds it could be redone.

There is videos on YouTube of it with 2TB of flash.

fcanesin··on Successful room temperature ambient-pressure magnetic levitation of LK-99
Yes, in two forms:

First it shows a temperature graph vs moment, as they heat it it loses the diamagnetism around the temperature LK99 is said to be superconducting.

Second only a superconductor will have net-zero field, which means "stable" levitation. In the video they approach the sample with the magnet and flip it while the piece is mostly "in place". A regular diamagnet generates a external field that "follows" the field applied so it would likely move sideways, that is why to "levitate in place" a diamagnet people normally use a Halbach array.

EDIT: A Halback array is made alternating the poles N-S of the magnet, so that forces of repulsion created by the diamagnet cancel. This is why you will see people using multiple magnets when levitating pyrolytic graphite.

fcanesin··on Show HN: Automated resume writing with AI
Looks great, now we need an AI to read and select resumes for a given job description created by another AI from the AI analysis of the business data.
fcanesin··on LCD TVs won’t see any further development
Lots of comments regarding LED brightness for sun lit spaces. If you are suffering with that have a look into Samsung The Frame (2022 and later) series. They have a special coating that removes reflections, I have installed multiple of those in very bright places and the mate finish works marvelous well.
fcanesin··on AMD Expands AI Product Lineup with GPU-Only Instinct Mi300X with 192GB Memory
MI300A looks really nice, if only one anyone could buy it and do a DIY "Mac Studio"-like linux machine. Imagine just swapping it for the next generation in 2 or 3 years and keeping all the rest: peripherals, case, motherboard and etc.
fcanesin··on Rodney Brooks on GPT-4
We known mathematics is the science of reality patterns, maybe if we can keep LLMs current ability in natural language and keep improving its (current poor) math abilities it will get there?...
fcanesin··on ZSTD 1.5.5 is released with a corruption fix found at Google
unlikely it affects high compression
fcanesin··on My First Impressions of Web3
Great post, but IMHO it should have been called "My First Impressions of Ethereum". The web3 ideal and movement is much larger than Ethereum only, and many are focused on solving these issues. For example Mina allows for mobile clients to verify the blockchain using recurring ZK proofs.
fcanesin··on The Brazilianization of the World
"The important stuff—the really valuable ideas—were now protected by intellectual property rights"

There are several reasons why China/Japan/Korea had very little regard for international IP on its high growth years - Brazil should do the same. Being per capita poor means that majority cannot consume imported goods, sometimes those are important for further development like machines, methods and tools - for small and even medium size entrepreneurs.

fcanesin··on Cinder: Instagram's performance-oriented fork of CPython
Why didn’t they simply invested in PyPy? Something that would continue and be maintained because of the passion and conviction around the project.
fcanesin··on India may build new coal plants due to low cost despite climate change
Do it, based on a 100-year average (or even 50) CO2-per-capita. The world will agree.
fcanesin··on The political case for a blanket cryptocurrency ban
What a idiotic essay, the same arguments could be made for the ban of most precious metal mining since majority of it goes to storage deposits.

Cryptocurrencies actually bring several benefits and better solutions for the problem of trust in a store-of-value or exchange contract. The world needs Bitcoin now more than ever, we are already living in a multilateral world where US and China exert pressure to force international contracts to be denominated in USD abs RMB.

That is an awful deal when both countries can print unlimited amounts and distribute to their preferences like happened during this pandemic, specially in the US.
