There are a bunch of different options to "bootstrap" iPXE in the first place. Least invasive is probably to boot it from a USB drive. You can also set up a traditional PXE boot process using DHCP/TFTP on your network to &quo

I agree that given two computable real numbers x,y, asking whether x=y is undecidable. The point I'm making is that it can't be true that x<y or x>y are decidable, because then x=y would also be decidable, and it isn't.

> Only x=0 is undecidable. That cannot be true, because if both x<0 and x>0 are decidable then x=0 is also decidable.

In theory you could do that, but it has its own costs and complications. And if you're going to add a big enough capacitor to ride out a battery swap, why bother with two batteries instead of just one?

Yes, that is exactly what I said at the beginning of this thread.

There's no problem if you use one battery, and there should also be no problem if you use two batteries and charge/discharge them both simultaneously (because then the voltages are matched). The problem shows up when you try to &q

by teraflop 2y ago
It would be convenient if it worked that way, but since the batteries are connected across each other in parallel, they will both be discharged simultaneously. And as soon as you hot-swap one of the nearly-discharged batteries for a charged

This looks like a pretty cool device! However, I was immediately curious about how the "dual battery" feature works. The IP5306 power-management IC seems to be designed only for a single battery, and as far as I can tell from the

What do you mean by "run into"? Zeno's paradoxes are thought experiments. The original paradox of Achilles and the tortoise purported to show that Achilles would never be able to overtake the tortoise. But of course, in a rea

If you try looking at the actual numbers or sketching rough tangent lines, you'll see that your "eyeballing" is misleading you. The graph is not at all linear -- the slope in recent decades is several times steeper than at th

No, that's wrong. The media mail rate is for books and other similar media, and it specifically may not be used for advertising.

Seems misleading for the headline to call this a "speed limiter", since depending on the implementation it either doesn't affect the car's speed at all, or slows it down in an immediately overrideable way. So there is no
