<!-- buttondown-editor-mode: plaintext -->This is my occasional newsletter, for my thoughts and explanations on assorted topics in software engineering and computer systems. It also receives notifications about new blog posts [from my blog](https://blog.nelhage.com/). Content clusters around my areas of expertise and interest in computer systems engineering, including testing, performance, and engineering system architecture and organization design, but I also wander further afield from time to time. In addition to my blog, I aspire to use this newsletter as a place to work through thoughts in a rougher form, and flesh out work-in-progress ideas; in practice, much of the time it just gets the blog posts links.
