Comment Re:Extra battery? (Score 2, Informative) 171

I would like to suggest one better: If your phone is one that allows you to remove the batter (i.e. not an Apple or a OnePlus or a few others), just get a spare battery of the type that the phone takes. When your phone dies, reach into your pocket, pull out the spare battery, and switch it for the one that is in the phone. It's instant, efficient, and doesn't require you to juggle your phone plus another box for whatever length of time it takes your phone to charge.

Additionally (and this is good for all phones), if you are traveling much by car, get a cigarette-lighter charger for your phone. Plug it in whenever you are in your car.

Comment Re:When did 300GHz become Terahertz... (Score 1) 47

Yes, I agree with you. The only possible explanation that I can come up with is that they must have dubbed the next order of ten over EHF as "The Terahertz Band". If that's the case, it needs a better name. If we are to assume that they are keeping with the general pattern used for radio signals, then this band would go from 300 GHz to 3 THz.

This would be an extension of the standard used to class radio waves into bands of an order of ten, which gives us VLF (9-30 kHz), LF (30-300 kHz), MF (300-3000 kHz), HF (3-30 MHz), VHF (30-300 MHz), UHF (300-3000 MHz), SHF (3-30 GHz) and EHF (30-300 GHz). VLF is truncated because EM waves below 9 kHz aren't considered radio. The lower ones are sometimes also called by wavelenth rather than frequency, so VLF-HF may also sometimes be called VLW, LW, MW, SW, though these are usually spoken full-length, e.g. "short wave".

Back on topic, I'll repeat: it needs a better name. EHF stands for "Extremely High Frequency" . . . what's more extreme than extreme? Hyper, maybe? HHF?

I have always suspected that the slowness of X11 over a network was primarily latency, not bandwidth. I think it waits for acknowledgement after each step before moving in, rather than (ironically) windowing the traffic. Paradoxically, adding compression to the mix may actually make things worse, because the compression and decompression steps, even if they keep up with the bandwidth demands, will add to the length of time it takes to get a request fully received, acted on, and acknowledged.

It's just a suspicion, though. I could be completely wrong.

I'm not sure I agree with you. If you think about it, McCarthy was an authoritarian douchenozzle as bad as any caricature of a commie that could be come up with, and he was doing what he did in the name of fighting communism.

No, I think the best way to diff the cold war versus now is with this regex: s/communist/terrorist/g . The players who are doing this shit now would have been the ones doing that shit then if they were born a generation earlier.

History repeats itself over and over. Here's an example: Think Freedom Fries are a new idea? Look up Victory Sausage.

Comment Re:Migrants (Score 1) 219

These are not migrants. Migrants come here, get jobs here, live here, rent homes here, buy goods here, pay taxes here. When they leave here, the job stays here for someone else to take.

In this case, however, the not-migrants are coming here only long enough to be trained to do the job. They are then returning to their home land, taking the job with them. Any benefit to the American economy is either transient (i.e. during their training) or restricted to the decision makers in the company carrying it out. In net, it is a loss to the American economy.

This is true of arbitrage . . . in general

I disagree with this point.

Arbitrage increases demand in the market that the arbitrageur is buying from, and increases supply in the market he is selling to. This has the effect of flattening prices and moving product to correct market imbalances. Over time, any remaining delta in the prices of that commodity on those two markets is going to be close to the arbitrageur's costs.

Your suggested interval is too much work, BUT...

If someone were to figure out the MAC address of his cell phone's WiFi interface (assuming it isn't an Apple that scrambles MAC addresses), a volunteer-run network of consumer-grade routers scattered around the city could get a pretty good fix on his location. I'm using the term 'network' very loosely here, of course; it's a network in that they're affiliated, not in that they're functionally connected. It would be 100% legal and inexpensive to do.
