Show HN: An index of all monthly dividend stocks
In my quest for finding high yield dividend stocks, I've noticed there isn't really a good tool for finding such stocks (that I can find, anyway), only pay-walled sites that are confusing and inaccessible. This little project seeks to remedy that.<p>I'm sharing this in the hopes that you'll find it useful, but also to get feedback, in particular, about monetizing. While I built this to be useful, I would like to make some money on it, so if you have any recommendations, I'm all eyeballs. I fear I may have to resort to advertisements to keep the barrier to entry low.

Show HN: Matcheroni, a tiny C++20 header library for building lexers/parsers
Howdy HN, as part of my ongoing programming language experiments I've ended up creating my own C++20 lexing and parsing library of sorts.<p>Matcheroni is an alternative to parser generators and regular expressions that uses trees of C++ templates to implement highly customizable lexers and parsers that have minimal impact on build times or binary sizes, while still remaining comparable in performance to Boost regular expressions.<p>The repo includes two example projects - a simple regex parser in ~300 heavily documented lines of code, and a much larger but not quite finished C99 lexer and parser.<p>All feedback appreciated!

Show HN: My platforming game written in C 89
I have been working on this game somewhat sparsely for the past three years or so. However, it is still in a very early stage, and there is a lot of work to do.<p>One of my friends encouraged me to post about it here, since he felt people might find interesting how I don’t use any libraries for it.<p>The game can be played on a browser by virtue of WebAssembly. There are native ports using either MiniFB or SDL2, but you have to build those yourself.<p>I decided to write the game in C because I feel like it is a simple language that a lot of people can understand well enough, and I didn’t think I needed anything more involved or complicated.<p>Over time, the game’s code became complicated, and I decided to use advanced features such as coroutines and higher order procedures, besides general overly engineered abstractions.<p>But then, over time I grew to feel like a lot of those abstractions didn’t really add anything to it, and just made it more complicated (and oftentimes more buggy) than it really needed to be, so a few weeks ago, I made a significant refactoring to it to remove all of those abstractions without removing almost any features from the game.<p>Milestones are released effectively whenever I get the game’s code to a decently presentable state. Sometimes, this means there are a lot of changes and big refactorings, but sometimes it means there are only a few small changes.<p>The game uses a simple 2D model system to generate images for the character’s animations dynamically during initialisation. (The source code can be browsed using a web browser on its page.)<p>The character can be controlled using the arrow keys or “WASD” (“A” and “D”) (double-tap a direction to jump).
