Ten Minutes, 16 Megabytes
A Parameter-Golf Field Report
By Billy Li & Tim Shen
A hypothesis-by-hypothesis field report from OpenAI's Parameter-Golf challenge — train the best language model you can in 10 minutes on 8× H100s, with the artifact constrained to 16 MB. Six sections, ~30 hypotheses. 3-seed mean: val_bpb 1.06184.
Coding Interviews
The original essay plus category notes on arrays, heaps, trees, graphs, DP, and backtracking.
ML Pointers
MLE, MAP, logistic regression, SVMs, and the classical machine learning foundations worth keeping fresh.
Theory Notebook
Probability, statistics, inequalities, convergence, and the mathematical instincts underneath modern ML.
Linear Algebra
Motivation, resources, and the geometric facts that made linear algebra finally click for me.
