I think you might be reading a bit much into it. People have blog posts with their pets, children, a random vacation spot, or just a random picture they wanted to share; I'm not sure why the anime girl is that different. Or is there some extra context I am missing?

It's just art that the author puts in all their blog post. I think it's perfectly normal.

You'll find the most cracked C++ programmers are either transgender, gay or anime fanatics. It is what it is.

First time here?

Just teasing - but there's a pretty large overlap of skilled FOSS developers and anime afficionatos (and also LGBT). It's a pretty common joke that if an exploit drops with an anime girl on the video / account - you know it's about to get bad.

Looking at the blog, this is a common theme with them: every article starts with a shot from some anime. Their GH PFP matches: https://github.com/16bit-ykiko

Hard to say why - maybe that's what they're watching when they made the article or did the work or something? Maybe they just like it. Maybe they're degens. People can be enigmatic sometimes. Well... okay, they're a C++ developer, they're definitely a degen.

Anyway, the first few times may catch you off guard, and sometimes it goes too far, but you learn to tune it out pretty fast. It's harmless and I'm glad they're enjoying themselves.

I mean this with no offense, but I find surprising reading a comment such as yours when in your profile about says "they/them"
