Sometimes technology can replace jobs in a way that improves overall quality of life and safety and that is not reassuring to those who lose their jobs, and society really needs to provide a safety net for people caught by that

My experience is that while yes this is literally true what actually happens is that you get given an iron ring so that you can open beer bottles with it

APPARENTLY people are just not familiar with the "The Aristocrats!" joke and so it keeps falling flat when I use it as an analogy for the security model around bearer tokens

The fun thing about the Omarchy "We will fix Linux on your laptop with AI" approach is that it's unlikely most of that will ever go upstream, and then they will have to deal with (a) the actual cost of rebasing everything for new releases and (b) the user cost of things breaking with new releases

Libraries in the software sense are called libraries because back in the day there was a cupboard full of paper tape implementations of functions that had already been written and if you wanted to use that function you took it out of the physical library and copied it into your code then returned it

"The Transformers do not endorse the views of the President" okay, great, yeah, it's very normal that you had to say that. This is an ordinary world where things make sense. It's normal that I'd wake up to an official statement from cartoon robots denouncing the man who has the nuclear codes.

Extremely short but specific dream in which I learned there was an internet subculture devoted to a conspiracy that we never see Sonic's left arm (which we obviously do) because it's "weird" and now I wish I had any artistic ability whatsoever because I want to share the "Weird arm gang" memes I saw

The UK government should absolutely deal with the current situation in the same way it did in the troubles - accept that the police are corrupt, send in the army to restore order, and then have the army murder the victims oh wait hang on

The longest sperm cells known to exist are produced by Drosophila bifurca, a species of fruitfly. Uncoiled, they are 20 times the length of the fly itself. The only explanation we have is because they somehow started competing on sperm length, which is a great argument for biology being stupid.

You know what even locally hosted LLMs are great at? Reverse engineering the proprietary code of big tech and writing copies that are, we are repeatedly told by big tech, not copyright infringing. I am really looking forward to AI companies trying to thread that needle in copyright law.
