Math Academy pulled me out of the Valley of Despair (bearblog.dev)
When it comes to learning a new skill such as how to drive a car, playing a sport, or an academic discipline, there is a unique relationship between a person’s confidence and their level of competence at different points of the journey.

I compared my daughter against SOTA models on math puzzles (michalprzadka.com)
I created an AI math reasoning benchmark using puzzles from this year’s GMIL competition — a long-running international mathematical challenge that I participated in myself back in 1998. The results are quite interesting: some of the most advanced AI models performed comparably to my 11-year-old daughter, while others struggled significantly. This experiment gives some amusing insights into current AI capabilities in mathematical reasoning, especially when compared to human performance at the middle school level.

Benchmarking RSA Key Generation (filippo.io)
RSA key generation is both conceptually simple, and one of the worst implementation tasks of the field of cryptography engineering. Even benchmarking it is tricky, and involves some math: here’s how we generated a stable but representative “average case” instead of using the ordinary statistical approach.

SFO Ballot Measure Reflects 10-Year Battle to Reinstate 8th-Grade Algebra (justequations.org)
The San Francisco Unified School District, which pulled algebra from its middle schools 10 years ago in the name of equity, will bring the course back next fall, ending a controversial experiment that some say squandered the opportunity for advanced learners to excel in mathematics—and did little to close the achievement gap.

California Discourages Schools from Offering Advanced Middle School Math (2023) (reason.com)
A small but growing number of American schools are reducing or delaying access to advanced courses. Most often, these changes have been enacted in the name of reducing achievement gaps between demographic groups. However, rather than helping marginalized students, these policies deny educational opportunities for gifted students of all backgrounds.
