Edit: I just did the first release, which you can check out on ccode.kronis.dev, or go directly to the Itch.io page to either download or buy the pre-built binaries or look at the source code. It's a simple utility and it's early on (consider getting it for free first and only paying…

Still less do I like people adding tracking stuff to my URLs. https://chrismorgan.info/no-query-strings?ref=example.com? Did I ask? If I wanted to know I’d look at the Referer header; and if it isn’t there, it’s probably for a good reason. You abuse your users by adding that to the link. https://chrismorgan.info/no-query-strings?utm_source=example&utm_&c.? Hey! That one’s even worse, UTM parameters are for me to use, not you.

With Move Forward: Save Scouting, we can be relevant to society, improve programming, ditch unsound practices, and streamline the experience. When the Boy Scouts of America, recently rebranded as Scouting America, gathers in Dallas May 11-15 for its National Annual Meeting, its leaders will confront a crisis that messaging cannot solve. At the end of 2025, the organization’s market share sank to about 1.25 percent of American youth, the lowest since about 1923. The organization…

This tree forms the foundation for most sparse factorization software, even when the underlying assumptions of Cholesky (symmetric and definite) do not apply. Ultimately this tree tells us two things: 1. where nonzeros appear in the matrix L even if…

While it is developed for MacOS, I've tried to make it as portable as possible -- however, it's likely you will still need to make some (hopefully minor) Significant tweaks to get this to run on Linux/other Unix systems. See Implementation Notes for more details. Requires Xcode Command Line Tools. Install with xcode-select --install. ymawky only runs on apple…

Finding the right one at scale is the real challenge. Custom metadata allows you to attach key-value labels to your unstructured data — things like department: Legal or status: Final.By applying metadata filters at query time, your application can scope requests to the data slice required. This significantly reduces noise from irrelevant documents, increasing both the speed and accuracy of your RAG workflows.Show your work with page citationsWhen your application pulls an answer…
