Simple self-distillation improves code generation

https://arxiv.org/static/browse/0.3.4/images/arxiv-logo-fb.png
A large language model can improve at code generation using its own raw outputs through simple self-distillation, which fine-tunes the model on its own samples. This method improves model performance on harder problems and generalizes across different model scales and variants.

In this article, I want to cover the overall design of coding agents and agent harnesses: what they are, how they work, and how the different pieces fit together in practice. Readers of my Build a Large Language Model (From Scratch) and Build a Large Reasoning Model (From Scratch) books often ask about agents, so I thought it would be useful to write a reference I can point to.

The smallest ELF executable (2021)

https://nathanotterness.com/2021/10/annotated_elf_1.png
The author created a 120-byte Linux executable that prints "Hello, world!" by overlapping ELF and program headers, removing unnecessary metadata, and packing code into unused bytes. This tiny executable is a result of extreme minimization tricks that continue to be possible on modern 64-bit Linux, despite the limitations imposed by the ELF format.
