LLMs can natively read & write neural network weights
Asked to make Qwen3.5-0.8B better at math without gradients, Astra identifies an issue in its weights causing reasoning loops that Qwen’s own model card warns about, and fixes this by natively editing 0.016% of the weights. With the same sampling settings, this weight correction…

Zerovital
Gerovital is the pun behind Zerovital — trading the myth of H3 for the biology of IGF-1: keeping insulin and IGF-1 signaling low does more for your health and longevity than any procaine formula ever developed by the Romanian anti-aging company.

Integral Theory
A framework for biological, cognitive, civilizational, and algorithmic evolution sums up the Integral Theory. It posits that true superiority—whether in a living cell, an individual mind, a nation, a planetary ecosystem, or an artificial intelligence—is not a function of raw…

How to code Claude Code in 200 lines of code
But the core loop? It's exactly what we built here. The LLM decides what to do, your code executes it, results flow back. That's the whole architecture.

A guide for engineers and scientists
Because programming has become an essential component of engineering, science, medicine, media, business, finance, and many other fields, it is important for scientists and engineers to have a basic foundation in computer programming to be competitive.

Location validation on Subreply
Since 2014 when Subreply was launched, I always wanted for users to specify their location. After years of programming in Python I found a way to validate City, Country and Country formats in a simple and intuitive way.

Tolstoy's coding advice
You should only code when you feel within you some completely new and important idea, clear to you but unintelligible to others, and when the need to express this idea gives you no peace.

Invert, always, invert
...it is in the nature of things that many hard problems are best solved when they are addressed backward.

Habits of high-functioning teams
Our communications with each other should be guided by the robustness principle: Be conservative in what you send, be liberal in what you accept.
