Got the electronet out and set up, and now all the 4 legged animals are out on grass for the first time this year! They are sooooo happy. (And the llama doesn't seem to have any thoughts of escape, so that's great).

A herd of over a dozen white goats with a couple of brown and black goats sprinkled in. They are 100% concentrating on eating. They are in a bright green grassy area, with a tall wooden fence, tall spruce trees, and a large old yellow barn in the background. There are lovely poofy clouds in a bright blue sky above.

Listen, if you’re a white person, and you think you’ve had Szechuan food, you probably haven’t.

Most of the Szechuan restaurants in the USA lack a basic component: spiciness.

I say this because a friend from out of town just went to a Szechuan restaurant in Vancouver, thought it was going to be business as usual, and now he’s doubled over because the spice is too much for him.

He tells me, it’s so bad, that he feels the spice eking out of his pores. 🤣

The overhead for the AI on a minecraft ant is so great that the mod creators limit the colonies to just 20 ants to prevent lag. Fine for gameplay 20 feels like a lot.

Interesting the kind of things they do: remember the location of their nest, find a path back, collect leaves etc. are so taxing.

In the real world a colony of 1000+ is typical. Some colonies have millions of ants. And real ants have much more to "process" Kind of gives you a sense of the scale of the intelligence of a colony.

nerdetry:

I have a pretty developed and deliberate approach to the photos I make, in that I generally have a fairly clear vision of the final result I want to achieve when I'm capturing something, even for details like contrast and tonality.

Except for color toning. I almost never have any idea whether I will add a sepia tint or whatever. I'm totally ad hoc and inconsistent about this, and I often go back and forth several times before settling on a final version.

The person I know who used to critique colorizing B&W seemed mainly to object to people colorizing other’s work, especially historical photos. It seems like if you as the photographer decide to do that, it’s fair as you’re the creator.

A console is not a replacement for a GPU card.

A GPU card is a discrete component from a CPU. It has dedicated VRAM. You can remove it from your machine and replace it with a different GPU.

Meanwhile, modern consoles pretty much just have APUs. Don’t get me wrong, they have decent APUs. However, an APU in a console is not a GPU card replacement – because it is neither discrete nor replaceable.

New thread on my big ongoing embedded project since the other one was getting too big.

To recap, this is a pilot project for a bunch of my future open hardware T&M and networking projects, validating a common platform that a lot of the future stuff is going to run on.

The primary problem it's trying to address is that I have a lot of instrumentation with trigger in/out ports, sometimes at different voltage levels, and I don't always have the same instrument sourcing the trigger every time.

So rather than moving around cables all the time and adding splitters, attenuators, amplifiers, etc. to the trigger signals I decided to make a dedicated device using an old XC7K70T-2FBG484 I had lying around.

Of course, as with any project, there was feature creep.

I'm standardizing on +48V DC for powering all of my future projects as it's high enough to move a lot of power but low enough to be mostly safe to work around live. So I needed to design and validate an intermediate bus converter to bring the 48 down to something like 12 for the rest of the system to use.

The FPGA has four 10G transceiver pairs on it. I used one for 10GbE (not that I need the bandwidth, but I was low on RJ45 ports on this bench and had some free SFP drops) and the rest are hooked up to front panel SMA ports (awaiting cables to go from PCB to panel) to generate PRBSes for instrument deskew.

Since I'm pinning out the transceivers and am planning to build a BERT eventually, I added BERT functionality to the firmware as well (still need to finish a few things but it's mostly usable now).

And since I have transceivers and access to all of the scope triggers, it would be dumb not to build a CDR trigger mode as well. That's in progress.

Into the idea of car camping?

These "rooftop tents" turn into a car or SUV tent that sits on top of your vehicle, built in ladder to climb up, cushy bed to sleep on.

@N4JAW I grew up out West in the desert and also around a lot of evergreen trees. One of the amazing things I noticed back east (Baltimore, Pittsburgh) was how you can see so much further in the Winter than you can in the Summer.

Also, fireflies! We don't have those out West. Too dry I suppose.

I know you’re busy, so I forward things from time to time. I’m especially interested in tech in African countries because the point of view on tech and its usefulness is often so different from here.
Americans assume all the interesting tech/STEM news comes out of Silicon Valley when SV is just a small part.
