Wall Street Enters Darker Age With Most Stock Trading Hidde
"For the first time on record, the majority of all trading in US stocks is now consistently occurring outside the country’s exchanges, according to data compiled by Bloomberg.

This off-exchange activity — which happens internally at major firms or in alternative platforms known as dark pools — is on course to account for a record 51.8% of traded volume in January. "

How good old mud can lower building costs
Builders pour concrete into temporary molds called formwork. MIT researchers invented a way to make these structures out of on-site soil.

How good old mud can lower building costs

MIT researchers developed a method to use lightly treated mud, including soil from a building site, as the “formwork” molds into which concrete is poured. The technique deploys 3D printing and can replace the more costly method of building elaborate wood formworks.

This process results in a drop-in alternative for conventional jet fuel, slashing emissions by up to 95%, according to the company.

Daft idea. They should have added carbon footprint of the factory and its workers to the 25 gallons that they produced each day.
It looks like a fund raising excercise.
I can plant a tree a day to generate more carbon reversion than what that factory does.

I am not sure about that. The conspiracist in me says that somebody profited from a panic selling of overvalued AI companies' stock. All the big players in AI: Open AI, Anthropic, Palantir, Microsoft, Tesla, and AI hardware related Nvidia, AMD, SMCI are all vastly overvalued to the tune of trillions. So if you can trigger a panic selling, you can make hundreds of billions in a day. The mechanics of how to create another DeepSeek R1 is well understood for months. The cleverness of what happened is they documented step by step an easy recipe using only open source ingredients that any average computer science undergraduate can follow. You can build your own 'DeepSeek Rx' using a good home PC with 16GB+ vram and Ollama or similar. The recipe is on many GitHub sites. One guy on youtube did just that as a demo. He trained his 1.5B Qwen model for reasoning in just 15 minutes on his PC.

I am using DeepSeek releases since over 9 months. The results have been great all the time but are getting better and better. I am running locally on my Linux PC all Qwen based DeepSeek R1 models and they are all great. The 1.5B model works fantastic when you are using it in the q16 variant. It is really killer. Inference is not very fast since I am running all models (from 1.5B up to 32B) on my CPU Ryzen5 8600G WITHOUT a dedicated GPU adapter. The CPU uses up to 40GB of my 64GB RAM for the 32B model. With good prompting the results are fantastic and save me hours of work every day. The dynamic memory allocation of the 8600G is great and allows me to run powerful LLMs with a small budget. My PC has cost me $900.

The thing about planting trees to remove carbon is that it makes no difference. In the end - at some future time - probably in about a hundred years that tree will come down and liberate all of its sequestered carbon. This would be fine if all carbon emitted to the atmosphere was from the biological carbon cycle.

It isn't. WE have been digging up fossilised carbon and liberating it. Two thousand, billion tones so far. Fossilised carbon release can not be counteracted by tree planting. Tree planting carbon sequestration is temporary only unless we cut down the trees and bury them permanently.
