Insurance, NRC and NIMBY's are the biggest obstacles. Lower pressure, molten-salt, smaller reactors like DMSR/MSRE @ ORNL and Taylor Wilson proposed with smaller, mass-manufactured reactors with scram/reprocessing pools benea

Yes. Back some 20 years ago, I switched majors, spent another 1.5 years and $15k for a degree accreditation eligible for PE. I'm fine with forbiding speech regarding life/safety impact like shouting "fire" and protecting

What would make device drivers safer: - Microkernel OSes - one driver failing is okay, because it runs in mostly in user-space. The big gotcha in microkernel design is transactions that touch multiple components. Some sort of across-driver

Nice. Two phase flow is a difficult subject, so much so the owner of a nuclear engineering consultancy I worked for wrote his magnum opus on it: Two-Phase Flow in Complex Systems It's imperative to get right in process environments

I remember one year in Campbell, CA, someone thought it would be a good idea to unload an AK47 clip in the creekbed. Police had other ideas but they at least they didn't get caught. Getting caught with an ATF NFA Class 3... Better Call

Lol. But seriously, the irony is CD-ROM's degrade to completely unusable within a century due to disc rot. A CD-ROM made with gold and completely encapsulated in an extremely stable enamel might work. Then, leaving universal instructio

Yes. All-or-nothing, black-and-white thinking appears to be a cognitive simplification that discards nuance in order to model the world more simply. Being depressed takes more effort to think and do almost everything that would/could b

My HP 48G(X) from the 1990's did automatic symbolic differentiation and integration. And, IIRC, there's probably a textbook in either Fortran or C for symbolic mathematical evaluation (partial evaluation, simplification and Monte

I have a friend who knocks off expensive and vintage RC ICE's in China by casting with minimal machining. Does it more as a hobby than gray market counterfeiting imposing on brands.

Is the app used in third-world countries? IE6 is insecure and only used on very old computers that can't install anything else. I'd check that the requirement is valid before doing a bunch of work.

When AI can code, design, publish to automated infrastructure and get feedback from users, the demand (and salaries) for developers and designers can/may drop precipitously.

Electronics learning kits from the 60's-90's had this, maybe they still do. Crystal earpiece, adjustable ferrite coil or variable capacitor, piece of wire as an antenna and ground to metal drainpipe. No batteries needed as the pow

Shocking that a. There was no error monitoring. b. That a SPoF existed. c. That it wasn't found sooner. The FCC, with their Verizon lackey Ajit Pai, should fine them $100 million bucks to get their attention, but they won't becaus

Sorry, free energy doesn't count as valid science but Apple did hire jugglers, musicians and other non-engineers in the past.

Absolutely. It's vital to listen carefully to users and think broadly and wisely. The programmer must understand what the users have to deal with in order to provide something useful to them. If not, the user will hate the result, it w

I've worked in biomedical informatics IT at a clinical research university. I think it's reasonable to understand what the user's goals and priorities are by going to the point of use, Genchi Genbutsu (現地現物), in order to ta

The better approach is to do only dynamic linking with dependency isolation (side-by-side multiple versions/configurations of a library that don't conflict with itself. no more RPM upgrade dependency hell.), package managed as ide

Yes, exactly. I think there's basically only three ways to teach EECS: stack top-down, bottom-up or as-needed/random. If students learned bottom-up, starting at silicon, they'd have a firm grasp, and be more mindful, of pract

Wow. That's next-level not understanding Nyquist bandwidth "records are better" extremism. I also get why Nakamichi or early Mark Levinson audio gear was outrageously expensive: they were like modern Apple but in the 1980&#x2

This is scary. I love and hate C, been using it almost 40 years. Its use seems more and more like juggling razor blades, wishing not to get cut but still always wondering when it will happen next. Rust, Pony, Crystal, Go, Elixir, Haskell, O

Serious lack of redundancy in a life-safety critical-system. It should have: - 5+ AOA sensors of different types - discard any sensor values that are stuck or providing incorrect readings - have a spray, heating system (some do) and camera
