A 5 character a-z random string has log2(26^5) =~ 23.5 bits of entropy, way less than 128.

"But that's crazy, Morpheus. Thermodynamics says.."

"And where did you learn about physics, Neo?"

"..... In the Matrix...."

I get that tastes vary and some people apparently don't mind the hole punch in the display, but I'm curious why you list its presence as a hard requirement. It seems like it would make the display unnecessarily harder to source.

The Eagle one yours is based on says it needs 0.6 mm PCB to work. Is it just close enough not to matter?

Crimping an IDC cable.

(It works very poorly for this, and I speak from recent personal experience)

I genuinely hope both of you continue this thread, even as I think it's unlikely that you'll come to common ground. I'm finding it extremely helpful to clarify my thoughts on this type of situation.

Could you expand on the available diagnostic tools a bit?

Could potting prevent this, or can the whiskers "push through" epoxy?

> this is quite frankly very surprising to me.

If we let t be time in seconds, and f be frequency in Hz, the sine wave formula is y = sin(2pitf). The 2pi is the periodicity of the sine function. If f is 1, we sweep through 2pi once per second. If we let f be 2, then it sweeps through two times per second, and so on.

So, you can think of the lookup index as being the tf part, but with t counting in integer fractions of a second, with the caveat that you'll want to perform some interpolation between values.

If the waveform were more complex than a sine wave, then in the general case this "skipping agead" could cause distortion. A sine wave is one of a couple special cases (square wave being another, and arguably it's "cheating") where you're not skipping "too far" to cause distortion. (That relates to the Nyquist sampling theorem and low-pass filtering, as kens mentions)

If existence is pointless except for procreation, what is our children's purpose? To have children, in order to have children, in order to have children? This is unbounded teleological recursion, unless you allow for a basis case in which any given life also has meaning for its own sake.

Myself, I hope for more for my own two children than just that they have children of their own some day, just as my parents didn't have me only in order that they might someday have great-great-grandkids they'll never meet

Culture and ideas transmit through channels parallel to heredity. Celibate monastic orders are one obvious example.

I want to live in a diverse culture for a reason analogous to why I'm wary of agricultural monocultures: All it takes is the right virus to come along, and all of a sudden we don't have any bananas anymore. There are some tragic failure modes associated with strong, cohesive, anti-"diverse" cultures.

I was misremembering the specifics too, it turns out. It was much closer to do_brick(). Ugly.

If I remember correctly, in the FTDI case that was very unlikely to happen. It wasn't a case of `if (looks_fake) do_brick()`. Rather, it accessed registers in a way that they knew their implementation supported but that was buggy in a widely counterfeited version.

(And I understand it they did this knowing the effect it would have. It wasn't some accident.)

I've never intentionally turned on google Photos backup since I use Dropbox instead, but I still notice it turning back on periodically.

> So... what exactly become the merit of taxing land over property? If you tax property, the value of the land is included in that tax.

If land--but specifically not improvements to that land--is taxed then there's relatively more incentive to make productive use of the land. $1 of investment to improve the productivity of land by building housing or whatever is tax advantaged over $1 of investment to try to hold onto appreciating land in hopes it goes up.
