I re-took Computer Architecture recently, and we used their earlier book "Digital Design and Computer Architecture: ARM edition", and it was also excellent.

I was a programmer, and moved over to biology recently. I was very "wtf is R" when I started, but slowly its strengths are coming through. I found the combination of the REPL plus the IDE, and the language syntax, somehow give me the ability to play around a lot more than I expected. Unlike others, I find tidyverse (especially ggplot2 and dplyr, which reminds me a lot of pandas) to be quite intuitive.

From the Wikipedia article:

However, it is possible to implement saturating addition and subtraction in software without branches, using only modular arithmetic and bitwise logical operations that are available on all modern CPUs and their predecessors, including all x86 CPUs (back to the original Intel 8086) and some popular 8-bit CPUs (some of which implement the Z80 instruction set) are still in production.

Does anyone know what the implementation of this is, without conditional moves?

Do you mean for a teaching job, or just any job? Certainly in fields like biology, you can only be taken seriously by others in the field by having an advanced degree (which is really only the beginning).

In computing, in the commercial field, you can of course get by with no degree.

And for sports, the level at which you have to be competitive is getting younger and younger. So much more sports science/nutrition going in at the middle school/high school level.

For endurance-based sports, online coaching has really accelerated this as well.

For skills, you still really need in-person coaching.

BYTE mag and Creative Computing were the first computing magazines I read, and really kick-started my excitement with computers, even though everything was out of my reach (either too expensive as a kid, or running on computers that were too expensive for me to contemplate). I remember there was a library catalogue system written for the Apple II that I tried to "cargo cult" rewrite for my MicroBee (an Australian Z80-based computer). I had no idea what all the "CHR $4" calls were for, but loved the process of typing in the listings.

I checked out some subreddits on the mission, and left pretty quickly for that reason. It's nice to find some positivity and wonder at it. I love what Artemis II is doing, found the launch very exciting and a little nerve wracking, and can't wait until they get even closer to the Moon.

2026 BMW i3 - 900km WLTP from a 108kWh battery.

I had to do a double take: remembering the i3s as the little almost SmartCar-sized EVs. Great cars, I still see a few around here, but I couldn't imagine them extending the range of those to 900km!

Turns out they just released the i3 sedan, which is like a 3-series. And good to see they're making the design similar between the new 3-series and the new i3. I like the i4, but really need something more 3-series in size.

When money is gone, the military is gone.

I feel like the lesson from other countries is that the military will be the last thing to go. Public funding of everything else will be sacrificed to keep the military powerful, and leaders will be from the military. That will be a complete breakdown of democracy of course.
