Nested agency and grammar-based language models (39/n). • Formally titled as “Nested pushdown automata and context free grammars (1/n”). Renaming to better reflect the design project’s origins as an exploration into physical computation.

Nested pushdown automata and context free grammars (1/n). I am one of those people that needs to build something before I feel I understand how it works. In an effort to take a deeper dive into the Theory of Computation I’ve put together a nested stack machine in a FPGA. At this point the hardware seems to be working. Now the journey ahead is to start programming this bad boy and see how such an alternate processor architecture will work out in real world applications such as robotics.

@madietlx Best memory, they function as standoffs for the transistors. Otherwise, any soldering operation would wick right up to the case causing QC problems down the road.

@thesuperegonaut If numbers were agnostic as to their ordinal value, there wouldn't be any notion of a prime number.

@blind_via Nah. Just throw it over the wall to manufacturing. They can deal with the mess.

When you are designing your PCB. Plan for PCB manufacturing requirements. Plan for PCB assembly environment and how it will be assembled. Plan for how the PCB will be tested. Plan for the end user and how they will be using it.

@blind_via If you have to go with a SMT-only connector, then make sure that any case the PCB goes into, also has a mounting geometry that will offer some additional connecter support.

Through hole PCB connectors are far more robust and holding to the PCB physically than SMT connectors. The surface area of contact pad increases the strength of the connection and durability against stressfull forces on connectors

Anyone out there with experience using AI to generate simulation files for their Verilog code? ..Is it worth the effort?

Cautionary advice to current STEM students: "If you use AI to do your homework and exams, then you've already made yourself replaceable (in the job market) by AI."

@StatiQfit Almost impossible to find any image at all of a fully rigged tail tree. Here is the best I could find. This is why loggers still climb trees. Main tower (in far background), shotgun carriage, deflecting off a guy-line jack.

Competition climbing on smooth debarked poles with a safety cushion (net?) at the bottom is one thing. Trying this trick in real life is a good way to kill yourself; ..or end up a quadriplegic for the rest of your life. They still rig tail trees on logging operations, so this is still part of the logger's trade. But trees have bark that will rip your skin off when one of your spurs kicks out and you face plant into the tree on your way down.

For everyone's enjoyment. Your rope always hangs up on the bark. Old growth fir trees might have thick layers of bark that sometime slab-off on you, dropping out and taking you with them. There are ant's nests up there; ..no fun. The YT clip ends with the tree topping. But in reality, the climber's job is just starting. Another hour-plus of hauling cables and rigging up by hand. Setting everything up for the yarder to start running its cables through. Only then do you get to come back down. By then your body is just limp rubber. youtu.be/H8ILqgJBcrQ?si…

@_GPaolo Regarding your past thoughts on nested agency: have you thought about building something based on them? Hardware is the "other platform" for idea expression; ..something that always goes unappreciated.

Would love to start writing my thoughts in blog-form other than just through scientific papers. But somehow, this seems to be so much harder than producing papers.

The green traces show a chip designer’s worst nightmare! If they take too long to settle, it causes a serious problem that can’t be fixed after a chip is manufactured. Try out my updated metastability explorer tool here: zerotoasiccourse.com/metastability/

@blind_via A one page schematic for what is already an industry-standard circuit configuration? I could work with that just fine.

Lived there in the early/mid 70s. Every year the money from the reservation's timber sales was divided among the Hupas, but not the Yuroks. Was a tribal sore spot. Don't know if that ever got resolved. The running joke was that after the "injun" money was dispersed, you wouldn't recognize your friends because they would all be driving new rigs.

@wildiris19 @AeneasAwoken I know a guy who was service manager at the Dodge/Plymouth dealership in Eureka in the 70's. Told stories of them coming down and buying Chargers, Super Bees, Roadrunners then crashing them a few months later.

I grew up on an Indian reservation and there was a financial windfall for the tribe and they just decided to give all members a check for like 20 grand (this was the mid 00s). There were like 2 weeks were all the used cars, whiskey, pitbulls, and flatscreens got bought and then

Odell Beckham Jr. reveals the real math on a $100,000,000 NFL contract: • On paper → $100,000,000 • Actually guaranteed → $60,000,000 • After taxes → $12,000,000/yr • Car, house for mom, living → $4,000,000/yr • What’s left → $8,000,000/yr • Five years. Then it’s over. Forever “Can you make that last forever?”

@Autistic_Lauren Not unusual. I have no attraction at all to team sports. But sprint-cars or motorcycles on a dirt track; ..I'm all in.

It feels weird not being a sports fan during a major sports event. Everyone just expects you to be watching and to care about it to the point you kinda just have to pretend

@blind_via @peterktodd Of what I can see in the photo, most are antiques. Some are clearly black powder muzzle loaders. This raid was probably brought to you by the same people that think the "AR" in AR15 stands for "assault rifle."
