"its own spent fuel is only dangerous for on the order of a thousand years (600-1200), instead of the 30,000 from current US designs", hmmm, I get it, by reducing the dangerous period of nuclear waste from 30000 year to 600~1200 y

Well, look at your calc again. Transmission loss per my calc is actually 1 - 0.9^3 = 27.1%. At grid level, high efficient part(mainly stable industry loads) will cover up low efficiency of household loads.

Seems you have more detailed info. I just checked full-load efficiencies of transformers and it turned out to vary from 95% to 98.5% and the comprehensive efficiency can actually drop below 90%. If we factor in the loss on wires, I guess my

by mrjin 5y ago
10% loss was just meant for quick calc, and I did not even factor in the loss in power generation etc. And the assumption was only 50% of the capacity, so that would drop to ~150 miles. Again, it's claimed value, how much you can actua

Charging the battery itself alone might be efficient. Take your 90% efficiency as true, and assume electric motor efficiency as 90% too, now the net efficiency drops to 81%. To reach your home, there most likely at least one step-up transfo

This reminds me that once where was a store I visited pretty often, almost every single time I entered the store, I would most likely trigger the alarm and nope, I did not carry such tags. The culprit seemed to be the credit cards in my wal

Kinda match my perception. Such user data is already of huge business value and too hard to resist for any big companies.

I feel you might be a little bit too optimistic. Did almost much simpler thing when I was at university. It was much more involved than it looked like. There are so many gotchas you would never anticipate until you get started. The most com

Nope. For 2nd item, I don't see a reason why GFW would do that. I did see some domain names resolved to 0.0.0.0 or 127.0.0.1 which is nice and easy and unlikely going to cause a problem. And in most of cases, the host names were actual

Your description of the symptom was more or less the same with my personal experience, but the conclusion might be a little bit off IMO. I first tried to deploy proxies to google app engine and use PAC scripts to auto switch between them. I

Cannot agree more. USB-C is a big mess. I've quite a few of them in different specs. Some can do 100w PD, some support DP-Alt mode, some are Thunderbolt 3, and some are USB 3.0 and can allow a maximum of 2A, some even only support USB

USB-C is much more complicated than most of us would anticipate, I would prefer to make it more specific: 2 Thunderbolt and 2 USB 3.2 gen 1. And I don't know when was the last time I used SD, let's save it for something else. And

To cause complete data loss does not need much data to be written. I'm wondering how firmware can distinguish legitimate and malicious ones.

Technically yes, you were right, there is a chance for us to intercept the communication between PCH and the Intel CPU then reverse engineer the protocol or even directly RE the PCH chip and create a substitute. But how practical, I don&#x2

Agree. I'm genuinely want to click every ad I see to protect myself from being tracked. If that could be fraud, will there be anything not a fraud?

Cannot agree more. Since the the advertisers have that much to spend, let's make them to spend more for nothing. Also by doing so, it will literally put enough noise into the data those trackers collect and renders the user profiling u

The problem is really how can we be sure that a device claimed to be a camera is really a camera and can be trusted? But yeah, as the device is already physically compromised, there is not much can be done in OS' perspective.

Well, this thing is almost as good as BrainF*ck. If anyone has to use this, why not simply use assembly? Learnt COBOL and S360 Assembly which are obviously not great but widely used by almost all banks. COBOL is way too chatty, S360 Assembl
