  • GitHub Copilot introduced a new keyword a little while ago, “@workspace”, where it can see everything in your project. The code it generates uses all your own functions and variables in your libraries and it figures out how to use them correctly.

    There was one time where I totally went “WTF”, because it spat out Python. In a C++ project. But those kind of hallucinations are getting more and more rare. The more code you write, the better it gets. It really does become sort of like a “Copilot”, sitting there coding alongside you. The mistake people make is assuming it’s going to come up with ideas and algorithms for them without spending any mental energy at all.

    I’m not trying to shill. I’m not a programmer by trade. Just a hobbyist. But I’ve been trying to learn it off and on for the past 30 years, and I’ve never learned so much and had so much fun as in the last 1.5 with AI help. I can just think of stuff to do, and shit will just flow out now.












  • Everything’s “techbros living in a sci-fi novel”, until one day it isn’t.

    I’m only 42 and I have seen very incredible advancements made in my lifetime that I never thought would be reality as a child. Handheld mobile communications devices that allow you to talk and share media instantly with anyone on the planet, for instance. That’s some literal Star Trek shit. Or the fact we now have the equivalent computing power of all the world’s supercomputers in the 80s put together on our desks. Or RNA vaccines, instead of using dead or dying viruses, we can now reprogram the body to make whatever antibodies it needs.






  • the lower voltage they operate at calls for more attention to be paid to signal integrity between the CPU and memory

    And they aren’t kidding around, modern high speed signals are so fast that a millimeter or less of difference in length between two traces might be enough to cause the signals to arrive at the other end with enough time skew to corrupt the data.

    Edit: if you ever looked closely at a circuit board and seen strange, squiggly traces that are shaped like that for seemingly no reason, it’s done so that the lengths can be matched with other traces.
