Six-panel comic titled “Nullwing – AI policy.” A sarcastic penguin software engineer (Nullwing) and a rabbit engineering manager discuss mandatory AI policy training. The manager says humans must validate AI outputs. Nullwing scrolls through inconsistent content, remarks that it looks AI-generated, learns it is, and asks who validated it. The manager replies: “You are doing that right now.” The comic has warm retro office styling and humorous corporate satire tone.

Nullwing's code takes so long to compile that he decides to resign.
Programming Humor, sarcasm, software development. Engineering.

Nullwing is experienced software engineer who works at the edge of burn out. He is often grumpy, has a very sarcastic and dark sense of humor (cause he's been working in the industry for so long!).

What do you think about **collapsible if** clippy rule?

I doubt that I like it, at least in this particular case of nutype.

Interesting observation: LLMs may give very different responses depending on a language of a question.
I guess this reflects some cultural background.

I am developing a #mnemonic system that supposes to help to remember large numbers.
There are mnemonic systems already, but I think I have some improvement.
My one should be quicker to learn / more intuitive.
