  • UniFi seem to have dabbled with 2.5 GBE briefly and then jumped to 10. I’m guessing that 10 will be the way to go.

    You’re looking at cat 6A patch leads rather than 7. 7 requires different but RJ45 compatible connectors, I believe. Yes, I’m still trying to understand what the difference is.

    I have a 2.5G router, the CG Max. A 1 G switch (waiting for a reasonably priced 10 G) and a 10 G WAP. It’s a bit of a mess!

















  • that’s unrelated - AES-256 for example can be executed just fine on either a 32- or 64-bit machine. in theory there’s nothing stopping you from running it on an 8-bit or 16-bit CPU (although other considerations related to the size of AES’s lookup tables make this unlikely). from some random googling, here is an implementation of Chacha20, another 256-bit encryption algorithm, for 8-bit microcontrollers.

    I started out programming a 6502a in 1980, 680X0 a little later in 87, so I get that bit, but it’s easier doing operations on a larger register. I remember writing code for 8 bit multiplication of 32 bit floating points.

    I enjoyed and understood the rest of your prose though. Didn’t do much/any programming/low level after say 2005, and regret it now. Trying to re-learn but things have moved on so much.

    I take that there isn’t much motivation in moving to 128 because it’s big enough; it’s only 8 cycles (?) to fill a 512 (that can’t be right?).
