Democratic inputs to AI grant program: lessons learned and implementation plans

We funded 10 teams from around the world to design ideas and tools to collectively govern AI. We summarize the innovations, outline our learnings, and call for researchers and engineers to join us as we continue this work.

https://openai.com/blog/democratic-inputs-to-ai-grant-program-update

As AI gets more advanced and widely used, it is essential to involve the public in deciding how AI should behave in order to better align our models to the values of humanity. In May, we announced the Democratic Inputs to AI grant program. We then awarded $100,000 to 10 teams out of nearly 1000 applicants to design, build, and test ideas that use democratic methods to decide the rules that govern AI systems. Throughout, the teams tackled challenges like recruiting diverse participants across the digital divide, producing a coherent output that represents diverse viewpoints, and designing processes with sufficient transparency to be trusted by the public.

The Quiet Death of Ello's Big Dreams - Waxy.org

Ello launched in 2014 with big dreams, but the artsy social network suddenly shut down last year, deleting nine years of posts without warning. What happened?

A 2024 Plea for Lean Software (with running code) - Bert Hubert's writings

This post is dedicated to the memory of Niklaus Wirth, a computing pioneer who passed away January 1st. In 1995 he wrote an influential article called “A Plea for Lean Software”, and in what follows, I try to make the same case nearly 30 years later, updated for today’s computing horrors. The really short version: the way we build/ship software these days is mostly ridiculous, leading to 350MB packages that draw graphs, and simple products importing 1600 dependencies of unknown provenance.

• The total number of poles of an elliptic function in P_0 is always \geq2

• Every elliptic function of order(the total number of poles) m has m zeros in p_0
Hint: use argument principle and thus
Remark: as a consequence, if f is elliptic then the equation has as many solutions as the order of f for every , simply because f-c is elliptic and has as many poles asf

Weierstrass elliptic function

In mathematics, the Weierstrass elliptic functions are elliptic functions that take a particularly simple form. They are named for Karl Weierstrass. This class of functions are also referred to as ℘-functions and they are usually denoted by the symbol ℘, a uniquely fancy script p. They play an important role in the theory of elliptic functions. A ℘-function together with its derivative can be used to parameterize elliptic curves and they generate the field of elliptic functions with respect to a given period lattice.
