Where you connect a 2-pole breaker, the 2 poles of the split-phase are only a cm or so apart.
Now, you still have to be purely reckless to get hurt here, since you should have already dropped power to your box before attempting this madness, but I was just saying... If you didn't cut the power, a minor mistake could sign you up for a bad time.
Split phase is not 2-phase. It's literally generated from a single phase of utility power.
2-phase power *does* exist in US dwellings, but usually only some condos, and that's because large condo buildings generally get a 3-phase feed from the utility, and split out groups of 2 to individual units.
The problem is that, historically, there was a 2-phase system that had 2 phases that were 90/270 degrees apart
Those numbers are insanity.
3 phase systems deliver power in 3 phases that are 120 degrees apart. You can't get 90 or 270 degree phase alignments out of that.
so people in the industry believe that "2-phase" must only mean that old system.
What industry? I am heavily involved in the datacenter industry... We have multi-MW generators. We deal with serious power. One of our datacenters has its own substation. I guess that must not be the industry you're referring to.
Yes, the two "legs" are not really "+" and "-". I assumed that people were smart enough to understand that.
Smart enough to understand what? Those signs are nonsensical. Do you mean smart enough to apply the correct terminology to your statement? That's an interesting way of looking at things.
I think it's time for you to just admit you were wrong
MDUs in the US sometimes have 2 phase, because the building itself gets an actual 3-phase feed from the utility.
I don't think 2-phase is appropriate, because split-phase and 2-phase are different things.
That's like saying it's ok to call a peanut butter sandwich a tuna sandwich because they're both sandwiches, and what's the use of distinction?
Usually split-phase, actually, which is a single phase, and a pole of that phase inverted.
Though sometimes (My condo) you do get 2 actual separate phases off of a 3-phase distribution transformer, meaning I have 208 for my large utilities instead of 220.
Yes, indeed. Go read about flicker fusion thresholds. Only this time, go past the summary.
CRT displays usually by default operated at a vertical scan rate of 60 Hz, which often resulted in noticeable flicker. Many systems allowed increasing the rate to higher values such as 72, 75 or 100 Hz to avoid this problem
For the purposes of presenting moving images, the human flicker fusion threshold is usually taken between 60 and 90 hertz (Hz), though in certain cases it can be higher by an order of magnitude.
It's strange that a company that makes money selling high end video cards gets a result saying 'buy more high end video cards if you want to win'.
The same way it's strange for a manufacturer of gas masks to warn you that breathing mustard gas will kill you.
It's self serving, not strange.
Self serving does not mean false though, and this set of data isn't a surprise to anyone who has been gaming as hardware has evolved. Particularly gamers who have upgraded their machines and noticed instantly that they simply aim better the more fluid it is. It's almost like the brain can tell the difference between 8ms between frames, and 16ms between frames, or 32ms if you had a shit machine back in the day.
Where do *you* draw the line for the reasonable brain response rate for hand-eye coordination?
If you're telling me with a straight face that 24FPS is smooth, I'm forced to conclude one of a few things.
Either you have simply never seen a higher framerate newscast,
Your brain somehow can't pick up the difference,
Or you're just fucking lying.
Given that the 24FPS of celluloid wasn't in any way the "most a person can notice" but a tradeoff between the cost of the celluloid and "smooth enough", I'm going with the latter. You act like you've got skin in the game... You one of those nVidia haters?
You're not wrong about any of those points, however, I noticed over a decade ago that I performed noticeably better with some mice vs. others. I later learned it had to do with the refresh rate of the mouse.
120Hz may sound awful high to matter, and I salute your skepticism- but that's 8ms of latency. Which I assure you is a lifetime when you're doing precision hand-eye coordination that is largely autonomous.
These results don't surprise me in the slightest. I have seen this myself in a hundred LAN parties over the years. Even relatively unskilled players perform better on machines with higher refresh rates. It's smoother, and their brain simply does a better job at aiming, or shooting from the hip.
It can happen- there are good salaries to be had in most places... But you have to recognize that the median isn't a lie... High salaries are much easier to be had in Silicon Valley, even if the cost is higher. 6 figure job markets are limited in the cheaper parts of the country.
Also, I'm sure that's not the only appeal to San Francisco. I've been there. It's pretty cool. I like Seattle better, but may I just like dense cities, and you don't....
Either way, the population density of San Francisco makes it hard to deny that people *want to be there*
It's a good question. I'll answer.
Rowhammer allows you to flip bits in memory with specific relationships to memory you can access.
If one of the bits you're able to flip happens to be bits in a page table, and enough stars line up, allows you to flip access bits on pages you're interested in, the MMU will let you read them as you will. Meltdown addresses this problem by completely swapping out the kernel pagetables between context switches.
However, if even more stars line up, then you can potentially map pages back in.
Leaking information about the page tables does make that a much faster process.
To be clear: Rowhammer is a problem on all CPUs. This accelerates the speed at which Rowhammer can try to brute force a page table entry.
Only indirectly, as the study says sleep seems to help slow the progression of Alzheimer's. It does not speculate on its evolutionary origin.

An organism can develop all sorts of useless traits as long as they don't have such a negative impact on survival that the species goes extinct.
The part you keep missing is my left over is more than their 1/4th.
And I've lived in a lot of cities, including Killeen, TX. People shit in the streets in every city. It does happen more in bigger ones though.
You come across as someone who hasn't been places.
You're not wrong, you just missed the obvious connection between the government and the people who are the real estate market, in that they're not different people. Is that pure capitalism? Of course not. But then again- that's the fucking problem with capitalism.
I know $3500 a month sounds like a horrifying amount to you, but keep in mind the median there takes home over $7000 a month, after taxes.
I fit pretty squarely into the slightly-above-median bracket for SF incomes, living in Seattle paying not much less than their peak in rent.
I'm still shoveling a G or more a month to my family in the midwest, living their high life with their low cost of living, and while people may poop somewhere in the streets around here, the air isn't inundated with the smell of chicken shit, I'm not playing the will-I-get-killed-by-a-tornado-this-year lottery, and oh right- my house doesn't look like what would be a condemned building here. So there's that.
It's different, but I've been on both sides of the comparison. I'll keep the west coast, thanks. I may pay a shit-ton of money to live, but what I have left over is still more than the median take-home income of anyone in the south, and I live better for that.
Well, to be fair, San Francisco's median income is also double that of San Antonio's, and with the left over, they can still buy a few places in San Antonio on top of their place in San Francisco.
Is it? Is your hypothesis that workplace pay discrepancies are in fact based on Y chromosomal traits, thus precluding transsexuals women from being impacted?
Of course I call it logic... it was literally a logical train of thought in the form of an argument. What the fuck would you call it?
He demonstrated nothing other than random items of basic evolution
Demonstrated random items of basic evolution? My apologies if you're not a native English speaker, but I'm not sure what you're actually trying to say right there.
and proved nothing to negate the study.
Wait what? The discussion wasn't about the study. The study was about the affects of CSF cleaning during deep sleep. The further discussion outside of the scope of the paper was whether or not this was an evolutionary process.
Again, unless you're an expert on the topic...
Oh boy. An inverse argument from authority?
You're just full of the fallacious arguments today, aren't you?
and you also clearly are not or you'd understand actual logic, we shouldn't be judging until additional studies are done.
Ok, so again, you can't address a single point in the argument, and have to instead attack his standing to argue (and mine?)
You sir, are an idiot. Go take a debate class. Or any fucking class.
Random internet guy has demonstrated logic, while all you demonstrated is an ability to deflect from your inability to think critically with an ad hominem argument.
It's not a waste of time, otherwise evolution would have removed it.
No. That isn't how evolution works.
It does not seek maximum efficiency. If it did, you and I couldn't even imagine the form that life would take at this point in history.
Evolution seeks only to survive. If a trait is not harmful enough to affect your fitness function, it won't be selected against. Furthermore, even if it does, it may not necessarily every be successfully selected against- it may simply be selected *around*.

They are actually on neighboring breakers.
I know ;)
Those 2 poles are very close together.

The only way to get a 240v shock in a typical USA house is to somehow get connected to BOTH legs of the service, which would almost take intent.

+110V, -110V
Those signs are nonsensical. It's 110VAC. Each phase is equally positive and equally negative. What they are, is 180 degrees out of phase.
Usually split-phase, actually, which is a single phase, and a pole of that phase inverted. Though sometimes (My condo) you do get 2 actual separate phases off of a 3-phase distribution transformer, meaning I have 208 for my large utilities instead of 220.
