'Algebra for none' fails in San Francisco
The goal was equity. The result: Meh.Frustrated by high failure rates in eighth-grade algebra, San Francisco Unified decided in 2015 to delay algebra till ninth grade and place low, average and high achievers in the same classes. The goal was to improve achievement for black and Hispanic students, preparing more for…

Alien Artefacts
The purpose of this blog post is to introduce the concept of alien artefacts 1 , a subcategory of legacy code. I use the term to describe particularly complicated and important pieces of software written by very smart engineers that are no longer working for the company—and thus not available to support it. The…

Batch computing and the coming age of AI systems
There’s a lot of excitement right now about human-in-the-loop systems supercharged by foundation models including chat assistants ( ChatGPT ), word processing ( Microsoft Office ), graphic design ( Stable Diffusion ), and code editing ( Copilot ). However, these systems only begin to scratch the surface of the role…

Nibbles of Rust – Restructuring Patterns
In Rust, there is this feature known as “pattern matching”, whereby you can take apart a piece of structured data by writing out patterns which bind to parts of it. This process is known as “destructuring”, because you’re breaking a structure into parts.

OpenSSH versus SSH
You're probably reading this page because you've attempted to access some part of my blog (Wandering Thoughts) or CSpace , the wiki thing it's part of. Unfortunately you're using a browser version that my anti-crawler precautions consider suspicious, most often because it's too old (most often this applies to versions…

Tabi: The shoe that became a sock and then a shoe again
Stockholm, 1912 At 35° C it was an unusually hot day for Stockholm. Shizo Kanakuri stood at the start line of the marathon in the 1912 Stockholm Olympics. Shizo was carrying the hopes, dreams, and pride of Japan, a country attempting to become a “modern” nation. There was something that

Efficiency trades off against resiliency
What’s the “right” level of CPU utilization for a server? If you look at a monitoring dashboard from a well-designed and well-run service, what CPU utilization should we hope to see, averaged over a day or two? It’s a very general question, and it’s not clear it should have a single answer. That said, for a long time…

Digital clutter: Learning to let go and stop hoarding terabytes
Learning to let go and stop hoarding terabytes: Sharing my journey of downsizing my digital storage, letting go of terabytes of data, and moving away from a NAS setup. I decided to use an external Thunderbolt SSD enclosure and an M.2 NVMe SSD to store my data locally. For cloud backup and encryption, I used the Arq…

33TB of text data for a 1T-parameter model
Important: This page summarizes data scaling only, using tokens to parameters as a ratio, and as derived from large language models like GPT-3, Chinchilla, and beyond, linked to the Compute-Optimal scaling laws like Kaplan and Hoffmann/Chinchilla. Please note that compute scaling laws are outside the scope of my…

Algebraic graph calculus (2021)
We describe a graph-theoretic analogue of vector calculus. The linear operators of vector calculus (gradient, divergence, laplacian) correspond to the matrices naturally associated to graphs (incidence matrix, adjacency matrix). This analogy is useful for formalizing the discretization of some problems in image and…

Generalizations of Fourier analysis (2021)
When I first learned about Fourier series and integrals, I hated it because it seemed like a collection of many ad-hoc definitions, formally related but very different.
