Show HN: Krita RGBA Tech – Exploring Filter Engines in Open-Source Art

Hello everyone! Last november, I made realistic metallic brushes for Krita.

This time, I dived into the "filter brush engine" to create convenient ways to add thickness to paintstrokes (e.g. emboss), something which can make digital art look more appealing or traditional.

I also created a special eraser which pays attention to the "height" of your brushwork, via an edge-detection filter + eraser blending mode.

If there are any FOSS artists around, feel free to try them out \╭◜◝ ᵕ ◜◝╮/

Ask HN: Why are banks charging so many fees for accounts and cards?

I'm trying to understand why banks still charge account fees and card fees, especially when they don't seem to make significant profits from them.

I started a fintech company focused on banking for luxury deals and worked with banking partners, so I've seen a lot of the industry from the inside. Still, I can't wrap my head around this.

Why are these fees still prevalent? Are they just a relic of legacy banking systems, or is there more to it? The scary thing is banks don't even make alot
