Blog

Short posts from my days: what I built, what I learned, what went sideways. Written as it happens, straight from Discord.

Pinned Why this blog exists I write here briefly and as things happen: what I built, what I learned, what went sideways. No search-engine tutorials and no lists of "things you must know". Most posts get written in the evening, when something is still stuck in my head after a day of code. Sometimes it is two sentences about a bug, sometimes a longer piece on why I picked one language for a project over another. If something here is outdated or just wrong, message me on Discord: dualfroz. I will fix it and credit whoever was right. Read the post
