Andrade is the namesake of Andrade creep due to his work in the early 1900s, but the existence of creep had been known for a long time by then. I'd imagine smiths have been aware of creep throughout the history of metallurgy. https:&#

What sort of experience did you have with fortran that led you to feel this way?

I chose a software analogy and digital example because this is a software forum. Don't read too much into it. In a different analogy, you could say that capacitance gives inertia to voltage and inductance gives inertia to current. The

Small caps near a chip are like an L1 current cache for all the transitor switching events.

Most could benefit from being modernized to use block diagram software like Scilab/Xcos. Learning is much quicker and more effective when there's an interactive hands-on component.

Your guest appearance on The Amp Hour podcast was the first time I heard about PartsBox and I've been using it ever since. https://theamphour.com/542-component-management-with-jan-ryc...

Many words have been written about this incident but it's a simple fact that they had no way of evaluating the condition of the hull. Successful dives don't mean anything because all materials degrade and they had no way of knowin

I agree, I wasn't disputing that.

Every electric car on the road has some amount of software-locked range. Tesla is just passing some choice along to you. The price must be higher for the harder-wearing configuration because the warranty is the same. It's good for cost

It's interesting to see how people react to being given choices that affect the life of the product. There's a design trade-off between price, warranty, and how (much) a battery is (dis)charged. When they don't give you opti

I agree with you in principle but the predicate accountability mechanisms currently are not functioning as they should for certain imports. E-bike batteries pose an outsized risk, hence the NY DRM carve-out.

E-bike manufacturers don't do repairs down at the level of individual cells because it's impractical to do so safely. The only sensible pack repair is replacing modules. Bicycle battery packs are often implemented as a single fiel

What if they did it the old way and simply never implemented deep discharge in the first place? The product would never tap into the extra battery performance, you'd retain control over what you bought, and they wouldn't extract m

It sounds like docker is maybe what got you started saving tools, but if not, how does it compare to your old method (virtual machines or whatever)?

Can you elaborate? I've appreciated it in a few specific situations but I haven't found where it's categorically better than the alternatives.

I haven't driven in mainland Italy but Google Maps is nearly useless in Sicily. Their road network is designed for itinerary-style navigation which to my knowledge no navigation app has a concept of. Like you said it's foolish to

Funny but there's still corrosion, cracking, and holes to connect wires to the battery.

The premise is that the enclosure is already somehow breeched. Squeezing a battery is bad and it makes bad situations worse.

The battery management systems in most personal e-mobility devices use outdated approaches for preventing thermal runaway, they're implemented inadequately, they don't try to predict it or they use outdated methods, and they lack

The D aspect of the FMEA I worked on was motivated by a reliability requirement, not by 7150.2. 70's NASA was using FTA and FMEA but avoiding putting numbers on top-level analysis. I imagine they did whatever ad-hoc analysis they thoug

I've done for NASA what they were calling FMECA and FTA for a subsystem. They had a lot of freedom to tailor the analysis to the situation, and the end result didn't quite match anything established. We addressed detection in some

I can't imagine, either, how it could make sense to do a computation like that in analog. I'm just saying it wouldn't cost $10 per multiply as part of a mixed-signal chip.

I'm not sure about this comparison. The AD633 priced as a niche product for a captive market, and the STM32F030F4 can't do the job by itself because it lacks a DAC.
