Comment Re:I run a WISP. No. (Score 1) 190

The biggest thing with the fibre (or copper) is if one core/cable isn't enough, you can run another one.

Whereas with wireless, even with directional setups there is only so much bandwidth in the aether. You can't just run another. So it will only ever be good for significantly less BW than physical lines, because it has to be shared.

But KPRF and LDPR are not pro-western yes men, so they don't count!

I guess you need to go down to parties with zero popular support to find one that aligns with US dreams for russia.

It's funny they never report that batshit-insane Zhironovsky*, has 12 times the support, and communists have 20x. That's how unelectable these people the US roots for are.

*some selected examples:
- expressed a desire to reunite countries of the ex-Soviet "near abroad" with Russia to within the Russia's borders of 1900 (including Finland and Poland).
- advocated forcibly retaking Alaska from the United States (which would then become "a great place to put the Ukrainians")
- Zhirinovsky, who encourages separatism within the Russian minority in the Baltic countries,[17] endorsed the forcible re-occupation of these countries and said nuclear waste should be dumped there.[31][32]
- advocated hitting some Chechen villages with tactical nuclear weapons.

There's simply too much great comedy this guy comes up with.

New capitalist Russia still lags the US. Hell it is barely back to best years of USSR standard. Capitalism made life expectancy drop like a rock for first 15 years. I imagine it was also shit under the tsar, even worse I'd guess.

Though Cuba has equivalent life expectancy to the US. So maybe there is more to it than the economic system?

Just one metric... double the alcohol consumption, and triple the tobacco consumption, per capita. (RU vs US). I'm surprised it only makes 10 years of difference to be honest.

But yeah, USSR is bad example. You generally had to work unless you were an invalid. It's not the same at all.

Comment old clunky junk (Score 2) 170

Not sure why the "hobbyist" community holds onto old crud like this when newer things are cheaper and better, win win. Darlingtons are terribly inefficient. It will work fine for turning on a lamp from your arduino but so will 10,000 different FETs.

Like people using ua741 opamps that are older than me. At least move into 1980 and use an LM358 or something. Same price or cheaper, and the input actually goes to one rail. Still very old junk, but significantly less so.

I guess people read some circuit from 1975 and figure they need to use the same parts verbatim, buy a bunch and are stuck with them making new circuits, that they then post, and more noobs buy the same old junk!

Comment Re:High Voltage DC more likely (Score 1) 597

Well, the reason datacenters use 48VDC is because that's what central offices used already, so the infrastructure was there, and they made hardware to fit.

The reason for that, though, is some combination of it being a high enough voltage to reach phones a few miles from the CO, without being so high that it would kill people. Now, why 48V instead of 50V... I guess is that it is an even number of lead acid cells (24, in this case). If you've ever been in a exchange, they've usually got the basement full of 48V batteries. (which is why the phone works when the power goes out).

Comment Re:Why Low Voltage DC? (Score 1) 597

Universal motors have that name for a reason, they're brushed and comfortable with AC or DC. (things like hair driers, angle grinders, food processors, etc. If it's small and noisy as shit, it's probably a universal. Generally for short intermittent uses, as efficiency and life is poor). Induction motors won't work though, as they need AC.(eg. furnace fan motors, compressor motors in your fridge, etc).

Every LED light I've ever seen has a internal SMPS, it should likely be fine with DC. So will SMPS wallwarts (phone charger) and computer power supplies (well, in 230V countries, or ones with universal input. (older, mostly?) ones with 120/240 switch won't work, as it uses voltage doubler for primary voltage... which doesn't work on DC).
