Pythagora-io/gpt-pilot: The first real AI developer
github.comThe first real AI developer. Contribute to Pythagora-io/gpt-pilot development by creating an account on GitHub.
Interesting. There are more and more of these coming out. For now I doubt they work very well, in practice. However the trend is clear and they will get better and better. Are our jobs at risk? Only if we don’t learn how to use these tools to up our game. A graphic designer or photographer that…

GNSS Positioning - A Reviser
semuconsulting.comThis article reviews the core principles underpinning the global navigation satellite system (GNSS). It references some of the key terminology, outlines the main potential sources of error, and describes how the application of RTK DGPS techniques can mitigate these errors to a large extent.
A super comprehensive introduction to GPS, with more detail than I have seen elsewhere. Also based on the second paragraph it seems to be quite up to date (2023)

jvns.caUsually when people say that a topic is confusing when I think it’s not, the reason is that there’s actually some hidden complexity that I wasn’t considering. And after some follow up conversations, it turned out that HEAD actually was a bit more complicated than I’d appreciated!
Julia Evans continues with her tour the force in depth explainers about how git actually works.

Clean Up Your Mess - A Guide to Visual Design for Everyone
visualmess.comThis is one of my favorite, super-simple, guides to creating nice designs. These elementary rules-of thumb go a long way to making professional looking designs - or just avoiding the most obvious design mistakes.

Write code top-down
teamten.comNice article but I disagree with the conclusion. I have found that you need to combine the two and go back and forth. There is no single way. By the way, notice that if you believe in TDD, that approach generally starts bottom up (UNITs are at the bottom.) so whatever design comes out of that…

solhsa.comA visual and simple explanation of the calculations for easing. I am not sure but I think some of this is over complicated. I mean I don't know that we need so many variations. In any event, it is much easier to follow because they pull out the bit that is needed.
