This is step 0. I suspect the real power will come in with composites. Even with metals, metal matrix can have very nice properties ( https://en.wikipedia.org/wiki/Metal_matrix_composite ) compared to a base metal. The k

Important caveat: It's not dangerous at all if streets are designed for it. My city's roads are a dumpster fire due to one-wheel idiot-devices, electric scooters, and other micromobility. With the exception of one-wheel idiot-devi

Let's say you're trying to control the x,y,z coordinates of a robot arm. It has three pivots. Rotating the third pivot can increase or decrease x depending on the first two. That's a complex, multidimensional, nonlinear syste

Microsoft has gotten pretty good at software development. Satya Nadella has been doing a surprisingly good job reforming everything about the company. That doesn't mean Windows wasn't absolute dogs--t for many years and isn't

One more -- and this comes up a lot -- anything where latency or a delay matters. An analog circuit can have response times in the tens or hundreds of picoseconds. A digital PID on something like an FPGA in the nanoseconds. One on a basic m

- Almost anything with right half-plane singularities. Although you can balance an inverted pendulum with PID, anything beyond that, PID falls flat on its face. - Anything where you want high performance. Lag and lead compensation is very o

I'll be the odd man out. No and on. 1) One of the key things in control systems is to deal with uncertainty. If you have a hundred trains, none of them should crash. You want a control system which you can understand to work even in co

A small EV, even capped at 25MPH to reach regulatory threshold of not being a car, with a range of <100km, with four seats (and optionally, no trunk, or a front trunk so you don't need all the mechanicals) would sell like hotcakes i

There are possible solutions. There was an early Israeli car company where, rather than charging, they'd swap the battery. Faster than filling a tank of gas. I don't think cars are worth owning unless you drive nearly every day. A

The whole point of PID is any idiot can tweak things to make it work. Ph.D means you're doing something like: * H2-optimization and optimal controls * System ID * Intuitive classical controls (Bode obstacle course, Nyquist, root-locus,

It seems like a very nice concept and start. I think if I were developing it, I'd find a school and do some gameplay testing with kids in an afterschool club. I might also ask kids and/or AIs to contribute art. It'd be nice t

This is enough detail that: - If you understand it, it's a nice visualization but you don't learn anything new - If you don't, you won't understand it. Going one click in brings up a paywall, with no pricing. You need to

In the nineties, emacs used to be the #1 text editor. On Unix. Which reached a tiny fraction of a percent of programmers. In that community, it felt overwhelmingly popular (competing with vi who was in a close second). Ironically, of the tw

This is dot-com rush all over again, but it's worth keeping in mind the dot-com rush (with some poetic license) gave us Google, Amazon, Meta, and much of the value of modern Apple+Microsoft. Those are five of the top ten companies in t

OpenAI does the same, indeed definitely much more often than Microsoft and probably more often than even Google. In fairness, it's all tagged beta. However: 1) Models change. Things I did a year or two ago behave differently, and usual

I doubt it. A lot of this is like voodoo and throwing darts at a board. Some people developed some intuition for it, but it's, well, random. We're evolving big things we don't really understand, and for reasons we don't

These investments don't seem either dishonest or stupid. Only a fool would buy compute capacity from Google (at least without a special deal), and Google needs apparent wins to sell GCE. They're paying with compute capacity for ad

Honestly, for Intel, it makes a heck of a lot of sense to get in on this game. It's just a question of getting the right deal. I really doubt they can compete with TSMC, Samsung, and GlobalFoundaries alone.

Bayraktar TB-2 versus Reaper: - 55kg payload versus 1746kg payload - 24k feet versus 50k feet altitude - 150km versus 1850km range It's not a fair comparison. They're very different classes of devices. I do think the US could prod

Public markets are intentionally set up to "benefits some parties that aren't really invested into the company" -- e.g. your retirement savings and your grandma's. That's a feature. Not a bug. Indeed, the main point

Capitalism and democracy are the worst forms of economic and political management, except for all the others we've tried. (Footnote: I still think there may be better ones out there worth trying. But I much prefer this to warlords rovi

I suspect if you've run into problems with a lot of things built on FUSE, the problem is FUSE. Yes, s3fs and sshfs can both leave the system in an unstable state. For example, there can be a dead mount which is impossible to unmount, a

I think we're talking about a difference in timescales. My experience is that culture naturally converges to incentives, but very slowly. If we were to evaluate teachers in ways which didn't align to tests (or not at all), put in

You can blame one middle manager. You can't blame a million middle managers. If all middle managers are doing something wrong, that's a problem of org design. The same is true across the board. One corrupt congressman? Bad apple.

I think those are a very different use case. sqlite is used for things like app settings. Both of those are heavyweight monsters designed for rather large data. That said, I'm reading their documentation right now, and I think one or t

I don't quite agree. There's a reason relational won, and continues to win more than a half-century after it was invented, despite no lack of wannabe usurpers. For your model to work, what would be needed is the reverse: a system
