Ask HN: How to build a light weight personal blog?
Shameless plug incoming.
A good while ago I created my own "system" Glyph: https://github.com/dbriemann/glyph
It's a static site generator utilizing Github issues and Github pages. If you are interested in how it works see: https://github.com/dbriemann/glyph-zero
As an example you can see a raw blog entry here: https://github.com/dbriemann/blog/issues/7 which results in https://dbriemann.github.io/blog/7-making-a-game-with-go-and... when "compiled".
You basically write your blog posts as github issues and the tool converts them to html which is then published via Github pages.
WARNING: this is not really maintained anymore because I rarely blog. Also it never had an official release .. so it is kinda experimental (but it should work, because it's simple).

Building a Sliding Puzzle with Go
We finally have a functional game! Now, we can work on a GUI for our sliding puzzle. I've choose Ebiten, an open source engine that allows us to build 2D games. It makes us implement an interface with the functions Update, Draw e Layout.

Lag Is Never Where You Want It... Or Don't Want It
Reading ebiten docs and source code they very clearly state that writing RGBA bytes to an image is slow, and shouldn't really be done every frame, at least many times per frame. This is where I thought my performance was being lost, and it sent me looking for answers for ages. Turns out, I was wrong and right.

Making Games in Go for Absolute Beginners
I love Go, yet I've never thought of it as a language with usable game engines. I'm extremely happy to find I was very wrong about that!
I'm woefully behind the curve on compiling to WASM, though, and I've yet to experiment much with tinygo so I have no idea how far I would get in creating a game people could enjoy in a browser without having to download a big bundle of assets. It's reassuring to see WASM mentioned explicitly as a compilation target [1] by Ebitengine though.

Is there a love2d for c++?
What about learning Go with Ebiten? Or Rust with Bevy?

What would be the closest thing to Unity/Unreal C#/C++ for Go to create games/animations/visual work?
Actually, there is a game engine in Go. Ebiten(gine) is actually really popular and has already been used for a few games in production

Mac + opengl
I noticed a similar issue when I got my MBP with the framebuffer not matching the window size and this has to do with the DPI settings. This GitHub link helped me understand the issue better and I hope it can be of assistance to you https://github.com/hajimehoshi/ebiten/pull/1811
