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.

Nim v2.0 Released
We have written pixie: https://github.com/treeform/pixie . Pixie is a 2D graphics library similar to Cairo and Skia written entirely in Nim. Which I think is a big accomplishment. It even has python bindings: https://pypi.org/project/pixie-python/
- How can I add graphics to my nim program?

Simple Gamepad Support
I made it because I really like pixie/boxy/windy combo, but there is no gamepad support built-in.

Why I enjoy using the Nim programming language at Reddit.
With Nim, you can continuously optimize and improve the hot spots in your code. For example, in the Pixie graphics library, path filling started with floating point code, switched to floating point SIMD, then to 16-bit integer SIMD. Finally, this SIMD was written for both x86 and ARM.

Is Fidget usable for implementation of 3D rendering?
The author Fidget actually has a number of other great libraries that are part of the rendering stack. Notably, Pixie for text and shape rendering in 2D, Boxy for rendering textures to the GPU via opengl, and then Windy for an OS window context and user events, and a number of other libraries related to 3D rendering.

Ask HN: What's the best source code you've read?
Perhaps not the "best" source code I've ever read, but libVF.io had some beautiful code for what's generally gnarly system-glue code. The iommu setup code is a good example and inspires me to think that system-glue code doesn't need to be gross or impenetrable: https://github.com/Arc-Compute/LibVF.IO/blob/master/src/libv...
Another one I've appreciated reading (and learned more about 2d graphics from) is Pixie, a 2d graphics library written in Nim. Here's the implementation of a fair subset of SVG paths: https://github.com/treeform/pixie/blob/master/src/pixie/path...
And one last one for basic algorithms: https://github.com/nim-lang/Nim/blob/version-1-6/lib/pure/al...
Of course Knuth's original code is still some of the best classic code. K&R's original C book is a classic.

How are Images Compressed? An explanation of JPEG [video]
I recently helped work on a new open source JPEG decoder in Nim. (Over here on GitHub: https://github.com/treeform/pixie/blob/master/src/pixie/file...)
This video was extremely helpful to understand the "why" of all the things the spec was trying to explain. It made a huge difference in us being able to get things working.
We talk a bit about JPEG and actually writing our decoder in Nim here: https://www.youtube.com/watch?v=vYwD7OynFcg
Overall, our concluding opinion is that JPEG has some extremely cool and really smart ideas for how to compress images but the binary file format itself has some very painful things in it (progressive and restart markers as a couple examples).

Nim: Curated Packages
I am working on OpenStreetMap renderer in Nim - see https://github.com/severak/lunarender3/ (but work somewhat stalled)
I needed some language which is:
- compiled to binaries
- and really fast
- has needed libraries (HTTP server, protocol buffers, sqlite and image generation)
- it's easy to set up
It was nice experience and Nim simply worked for my needs. People on Nim forum were nice and helped me when I ran into problems. It has nice and usable built-in library and I was really impressed by graphic library pixie - https://github.com/treeform/pixie
I would use Nim again when I when I will see this application is suited for it (e.g. some command line apps).

Building a simple room-based chat application in Nim (using HTMX)
> but not so small that there are no useful libraries written...
Says the person responsible for a ton of really useful, well-done Nim libraries, such as this amazing Cairo/Skia-like library: https://github.com/treeform/pixie#readme
Thank you for all the things you've made for Nim!

Codebases to read
I'm partial to how cleanly written https://github.com/google/leveldb is. It is a reasonable size to fully read & grok in not too long.

Open Source Databases in Go
goleveldb - Implementation of the LevelDB key/value database in Go.
What are some alternatives?
tiny-skia - A tiny Skia subset ported to Rust
RocksDB - A library that provides an embeddable, persistent key-value store for fast storage.
godot-nim - Nim bindings for Godot Engine
MongoDB - The MongoDB Database
Nim - Nim is a statically typed compiled systems programming language. It combines successful concepts from mature languages like Python, Ada and Modula. Its design focuses on efficiency, expressiveness, and elegance (in that order of priority).
Redis - Redis is an in-memory database that persists on disk. The data model is key-value, but many different kind of values are supported: Strings, Lists, Sets, Sorted Sets, Hashes, Streams, HyperLogLogs, Bitmaps.
canvas - Cairo in Go: vector to raster, SVG, PDF, EPS, WASM, OpenGL, Gio, etc.
SQLite - Unofficial git mirror of SQLite sources (see link for build instructions)
nlvm - LLVM-based compiler for the Nim language
LMDB - Read-only mirror of official repo on openldap.org. Issues and pull requests here are ignored. Use OpenLDAP ITS for issues.
