Dunn's Law of Information

Here’s the law in full rescued from its original wiki page. “What you don’t know, you don’t know - and you can’t make it up”. This law is attributed to former Raytheon vice president Bruce Dunn. Although Bruce used it in the context of evaluation of evidence for scripture, it is highly applicable in the case of cluster failure where all that is observed is inability to communicate.

Playing with Jan.ai

It was about two weeks ago when one of my coworkers asked me, if I was already replaced by AI. I was baffled. Jan.ai looks quite like me, it is friendly, it uses the waving hand emoji (👋) as a logo and it genuinely seems a great way of experimenting with a lot of different open source LLM’s. So i tried.

I did a few things again.

So, a few years ago I made a small flask-app, just to keep myself entertained. This was a few years after I did another minimal webapp in React. Since I just migrated to a new set of servers I thought, I fluff those apps a bit. Bring some color into them, upgrade to the latest versions, fix a few bugs and so on. Now I’ve got a set of interesting applications, all managed in the same flask-container, delivering some features that you might find useful....
