I feel like the RP2040 or RP2350 approach the simplicity of these older machines. https://www.raspberrypi.com/products/rp2350/ The documentation is pretty good. Reading it reminds me of going through the document

Seems so, TSMC had issues with keeping costs under control while building their fab in Arizona. The military is having trouble building submarines and ships at the same rate as China is capable of. Nuclear plants are being built way over

Another famous De Havilland aircraft, the Beaver: https://youtu.be/4wQjAB-jnI8 With commentary by Harrison Ford. Sounds like this plane wasn't De Havilland to start with, they just bought the rights to build them.

The further north you go, the larger the seasonal variation in sunlight. I've watched some video's of people living off grid in BC, they need a diesel generator for the winter months to get by.

That's strange, I had a friend that had a C64 and later an Amiga. I was always so jealous of how many more games he had access to than I did.

I remember the feeling of accomplishment of getting the game to run. It was better than playing the game in fact.

Back in the late 80's I had a Tandy Coco 1 that had a copy protected game called Dallas Quest. I spent some time copying all the sectors from the master to the copy, and it always got stuck on this one sector. I guessed that the game

I think Jensen Huang stated that Moore's law is dead a few times. I've seen projections of cost per transistor for the leading node being more expensive than the trailing node. The only reason to pursue it would be that the mark

Intel doesn't have a monopoly on leading edge semiconductor manufacturing. The company that kind of does is ASML, they are based in the Netherlands, but there's an office in Connecticut.

1950-1975 property taxes in Baltimore increased 19 times. It's double the rate in neighboring Baltimore county. In the 2010's Baltimore was losing 500 residents per month. The city is in a death spiral. 1950-1975 San Francisco

I used the sharing ability to run the fake login program on another node. The syntax was something like: [12] fake_login Where 12 was the remote computer I wanted to run it on. The networking was definitely ahead of what was possible with

The computers had a C compiler and Pascal interpreter made by Watcom out of Waterloo. QNX was the OS, which is also out of Waterloo I believe. So overall, the system supported a few Ontario based companies. There was a trackball integrate

My highschool had a lab of these in the early 90's. I would spend every lunch hour up there. Got my first exposure to a unix command line, although the commands were slightly different, ie. frel -> rm. I eventually figured out a f

When the Northeast power grid went down down in 2003, the Bruce Nuclear Power Development was almost entirely kicked off the grid. It was able to keep ticking over at a few percent of power output though because of a feeder line that went

The control rods don't stop decay heat from being produced. That's what happened with Fukushima. Also, nuclear poisons (neutron absorbers) build up after the reactor is shut down. After the control rods are withdrawn it takes a

Is there a cheap GPU you suggest? I was looking at NVidia P40's as they have 24 GB of ram, and cost a few hundred dollars.

Also it reduces latency of communication to the ground.

I guess talking about Kessler Syndrome is worth while here. A chain reaction where one collision, leads to more, which leads to more. It may be a slow motion chain reaction. https://en.wikipedia.org/wiki/Kessler_syndr

I know that some parasites secrete substances that reduce our immune response, for example hook worms. People that have autoimmune diseases of the gut sometimes see a benefit to purposely infecting themselves. I think our current genetic

I used a small FPGA when I needed to modulate a signal. Initially some people tried to use a microcontroller for the same purpose, but there was too much variance in the timing. In fact, initially even the built in silicon oscillator for

I think the ability for them to be reprogrammed makes them way more valuable than an ASIC. There is a performance penalty though, something like a 10x silicon area penalty, and 10x frequency penalty. But for some applications it's wo

Back in the 80's Intel tried to make a CPU designed for high level languages. https://en.wikipedia.org/wiki/Intel_iAPX_432 It was a commercial failure. The iAPX 432 programming model is a stack machine with no vis

I think it's a shame that we don't breed more fuel. The majority of mined Uranium 238 can be made fissile in a breeder reactor (fast neutrons), just like with Thorium. It does require reprocessing, which is a taboo topic due to

A similar example that's more closely related to healthcare is laser eye surgery. For years it was largely an elective procedure, insurance wouldn't pay for it. Clinics would open up in strip malls everywhere. The cost of the p

For context, that's around the time I entered University. I bought an HP48S calculator ($200 canadian), which I spent so much time on, it used 3 AAA batteries which would last for months. There was a whole hacking community around it

A very real danger is a nuclear power that has a deranged person in charge. They know they don't have much time left, they don't care what happens after they are gone, they decide to fire off all their nukes. https://e
