As a more general comment, I hope we’ll stop trying to discriminate whether a certain text was or not written/polished/extended by AI and focus more on content and author’s responsibility for what they do or do not say with that text.
I agree. Not because I think that most AI content is worth reading, but because it can be criticized on more grounded merits. People wrote blogspam by hand for two decades before AI started generating it. It wasn’t high value when a human wrote it either.
On many (most?) posts, far more energy is spent arguing about whether a post is AI than discussing if there’s anything of value in the post.
I've stopped reading anything on blogs on the basis that it's now probably llm spew and life is too short for the signal to noise ratio that implies.
With the exception of things that places like HN seems to consider worth reading, which is why I'm looking through the comments to this and others to find recommendations.
Matrix exists and really isn't too bad to self-host if you just want a small number of people. (If you federate with other servers, then you have more things to worry about -- increased attack surface, more visibility leading to more potential attackers, and the risk of unintentionally storing illegal content (e.g. CSAM) sent by people from other servers.)
The UI of Element (the most popular Matrix client) is more or less in line with any other chat app, but I guess it depends what you mean by "on par to whatsapp". Biggest downside I've found is that you can't search your messages on the mobile clients.
Altough I’m not an economist, it seems that the events shown in the graph coincide with the suspension of dollar - gold convertibility until then regulated by Bretton Woods monetary system
Sorry for my late reply. Touretzky's Common Lisp: A Gentle Introduction to Symbolic Computation holds up well as a good introduction. Steve Losh's A Road to Common Lisp is a great roadmap for going further (https://stevelosh.com/blog/2018/08/a-road-to-common-lisp/).
For tooling, you can get started with just sbcl and rlwrap, both of which should be in any Linux repo. Get a REPL with `rlwrap sbcl`. Exit with `(exit)`.
Yes the explanation is diffraction. As light passes through a lens, diffraction acts in similar way as a light through a small pinhole. Incidentally, pinholes and apertures are low pass filters.
