Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Ask HN: Any good books on ray tracing?
Physically Based Rendering[0] was an excellent textbook when I read it ages ago and conveniently enough it looks to have been updated with a new edition last year.

C++ Project to Put On Resume
Both of these books are free, and both are written in C++, but they can be done in any language. The first book, a raytracer in a weekend, is part of a series, you can find it here: https://raytracing.github.io/ And, if you get to the third book in that series, or you need a reference book, the PBRT book covers the math in more depth and discusses the latest theory, you can get the last edition of the book (5 years out of date) for free though: https://pbrt.org/

(Why) is a toy password manager a too complex summer project?
Making a “complete” one is a never-ending rabbit hole you can spend a lifetime on and is a very active area of research covering more advanced geometry, probability, optics, machine learning etc etc. A great introduction to that is https://pbrt.org

Suggestions for some best books on computer vision
This isn't the highest priority but if you haven't already, learn how computer graphics works. Get a working knowledge of the camera matrix, real time graphics (say, OpenGL but threeJS is an option), and photorealistic graphics. PBRT is the go-to for photorealistic graphics. The first two books of Foundations of Game Engine Development are way more useful than they have any right to be (and my favorite textbooks I've ever read, 10/10).

Org Mode Gripes
Org-mode strength though is in working with different languages in a same source file, which I am not sure if Knuths version does. Anyway, to see how the original idea looks like, check the Wikipedia article, or to see it in real-life see some of books that are written in the literate style, like Physically Based Rendering, which seems to be available for free nowadays or C Interfaces and Implementations.

Physically Based: A Database of PBR Values for Real-World Materials
I contributed a tiny bit to pbrt[1], and one of the things I loved was that if you just plugged in physical values you almost always got great results with minimal tweaking.
The Octane data seems most complete at first glance (with complex IOR etc), but for things like milk and blood I expected at the very least some absorption coefficient for the translucency or similar.

Ollama is now available on Windows in preview
But these are typically filling the usecases of productivity applications, not ‘engines’.
Microsoft Word doesn’t run its grammar checker as an external service and shunt JSON over a localhost socket to get spelling and style suggestions.
Photoshop doesn’t install a background service to host filters.
The closest pattern I can think of is the ‘language servers’ model used by IDEs to handle autosuggest - see https://microsoft.github.io/language-server-protocol/ - but the point of that is to enable many to many interop - multiple languages supporting multiple IDEs. Is that the expected usecase for local language assistants and image generators?

The Mechanics of mutable and immutable references in Rust
If you tried writing code like the one above, your Rust LSP should already be telling you that what you're doing is unacceptable:

A guide on Neovim's LSP client
A language server is an external program that follows the Language Server Protocol. The LSP specification defines what type of messages a language server can receive, and also how it should respond. The idea here is that any tool that follows the LSP specification can communicate with a language server.

The IDEs we had 30 years ago and we lost
> There's a strange dance of IDEs coming and going, with their idiosyncracies and partial plugins.
The Language Server Protocol [1] is the best thing to happen to text editors. Any editor that speaks it gets IDE features. Now if only they'd adopt the Debug Adapter Protocol [2]...

The More You Gno: Gno.land Monthly Updates - 6
The Gno Language Server (gnols) is an implementation of the Language Server Protocol (LSP) for the Gno programming language. It is similar to the equivalent “gopls” project for Go, as they can be plugged into your code editor through extensions and allow you to access handy features, such as autocompletion, formatting, and compile-time warnings/errors. Gnols makes writing code simpler, working with several editors to suit your preferences. To try it out, visit the CONTRIBUTING.md file, which contains instructions to get you started. Our current documentation targets Vim, Neovim, and SublimeText, but can likely be used with any editor that supports LSP. Feel free to contribute to improving Gnols and adding more features. It’s well-written, and simple to dive into the code and add more capabilities.

LSP could have been better
Honestly, you should read some of the docs [0] if these are the sorts of questions you're asking.

Show HN: Postgres Language Server
hey HN. this is a Language Server[0] designed specifically for Postgres. A language server adds features to IDEs (VSCode, NeoVim, etc) - features like auto-complete, go-to-definition, or documentation on hover, etc.
there have been previous some attempts at adding Postgres support to code editors. usually these attempts implement a generic SQL parser and then offer various "flavours" of SQL.
This attempt is different because it uses the actual Postgres parser to do the heavy-lifting. This is done via libg_query, an excellent C library for accessing the PostgreSQL parser outside of the server. We feel this is a better approach because it gives developers 100% confidence in the parser, and it allows us to keep up with the rapid development of Postgres.
this is still in early development, and mostly useful for testers/collaborators. the majority of work is still ahead, but we've verified that the approach works. we're making it public now so that we can develop it in the open with input from the community.
a lot of the credit belongs to pganalyze[1] for their work on libg_query, and to psteinroe (https://github.com/psteinroe) who the creator and maintainer of the LSP.

Nx Console gets Lit
The nxls is a language server based on the Language Server Protocol (LSP) and acts as the “brain” of Nx Console. It analyzes your Nx workspace and provides information on it, including code completion and more.

How to configure vim like an IDE
LSP stands for "Language Server Protocol", which defines how a language server and an editor (client) can communicate to provide code navigation, completion, etc. (source). Traditional IDE's would have something similar to this baked-in already, but proprietary to their software/language; whereas LSP is an open standard, so anything could implement it.
