The thing I feared most Was receiving your letter And then it arrived

He said he designed it for his use case of executing trusted configuration code, which some others appreciate. Obviously there was some misunderstand about the goals and priorities of the project. Making this change would cost him something

He also said to sanitize any data that you intend to use with the unsafe constructors. Taken together, he's pointing out that you decide how much you trust the data and you control which constructor to use. "Problem in chair"

I understood him to be speaking tautologically, that you trust the data when you choose the trusting library without using the safe constructor, whether or not you realize the implication. He seems very well informed that some people are us

by sheepshear 3y ago
A lot of people misunderstand what he's actually saying. There are two categories of constructors. One is for data that should not be executed, the other is for trusted data that should be executed. There are two libraries. One has def

I've always thought that the Xbox should double as a regular Windows desktop, but I guess I'm missing something about how that would not be the best strategy.

Making a strawman argument doesn't point anything out.

by sheepshear 3y ago
Yes, that's why we're having this conversation. It's so common that some people reasonably infer a stronger connection between units and physics.

Exactly, 4C is a quantity with temperature units. Units have no semantic meaning without context. Dimensioned quantities have the semantic meaning that you give them.

by sheepshear 3y ago
Again, you tell me. Units have no meaning without the context of what you're modeling. I can model the average temperature of your pieces of metal as (20C+15C)/2=17.5C.
102.
by sheepshear 3y ago
You tell me. Units help describe what you modeled, they can't stop you from modeling nonsense. I heated up your iron by 4 degrees and now it's 20C+4C=24C. I modeled the physical process of heating and the units provide some additi

How would you convert between Kelvin and Celsius if temperatures couldn't be added?

What about a MaskedArray? ndarrays are homogeneous by definition.

by sheepshear 3y ago
Why not use a structured array with an 'isna' field to use as a mask when performing operations?

Retroactive inspection revealed that it wasn't a hardware failure, but the computer didn't know that at the time, and hardware failure can look like anything, so it was correct to exercise its only option.

Failing over is correct because there's no way to discern that the hardware is not at fault. They should have designed a better response to the second failure to avoid the knock-on effects.

I get it I'm just surprised that's what you meant.

Implying there's a technical reason it couldn't be used.

by sheepshear 3y ago
I thought you meant "domain" like a field of work or study.

by sheepshear 3y ago
What's preventing it from being used?

"Toy" is solver jargon that sort of means there's an alternative that blows it out of the water.

Academic resources will never get to a useful punchline. Maybe try a hands-on course like this for general electronics and PCBs https://youtu.be/aqVgYasrBs0 Avoid lithium ion batteries. Use a deep discharge lead acid batter

Big companies buy solvers and support contracts, not interfaces. That's why everything has a crappy buggy interface slapped on it.

Whenever Dave says "a real X", he's referring to a specialized role at a company. It's not a dig at hobbyists.

Razavi has authored several well-known textbooks, one of which is on introductory microelectronics, the subject of these videos. Linear circuits are covered in prerequisite courses.

Not sure this YouTube series is the right fit for your project. Razavi's course is focused on signal processing (for future integrated circuit designers), whereas your project is power processing. Quite different approaches. The only c
