<p>Free VPN's are usually funded by agreeing to route some VPN traffic for other people though your own network. They basically work as mixers, randomizing traffic throughout the VPN population.<p>This can expose users to legal risks, but but can also add plausible deniability at the same time "it wasn't me, it was someone on VPN".</p>

<p>It's not stable, and no it's not theoretically possible.<p>A proton is the lightest stable baryon, and thus the only only stable one. It's not a coincidence - in particle physics if a lighter elementary particle is possible the heavier one will ALWAYS decay into it. "Whatever is not forbidden is mandatory." (Combination particles like atoms are more complicated because there are other things that might force the particle to exist.)</p>

<p>It's not actually a proton. And yes you can built a particle made from any combination. I posted elsewhere in the thread with a bit more details.</p>

<p>This is significant because binding 2 heavy quarks together is very hard to do because they decay so fast.<p>All the particles made from just 3 light quarks have been found. And I think all of the ones made with 1 heavy quark and 2 light ones have also been found.<p>This is only the 2nd particle made from 2 heavy quarks that has ever been found.<p>It's not a coincidence that both of those were made with charm quarks, because charm quarks are the lightest of the heavy ones.<p>None made of 3 heavy quarks has been found (yet).<p>Also: A particle made with a top quark is not possible - it decays too quickly.</p>

<p>You misread what I wrote. Water is the same solvent as both regular water and ultrapure, I was replying to the ultrapure part.<p>Also: I appreciate you found a source, unfortunately it's not true what they said. It's not possible to "leech nutrients through the hair to the scalp", the wrench story is not true either - there is zero chance a lab with the standards they have would just leave a wrench at the bottom of the pool - it would contaminate the water. Not to mention the bottom is filled with more of those light tubes, so there is no place for a wrench to sit. (And if someone dropped one it would break a tube.)<p>I don't know why someone would tell businessinsider such stories, but they are not true.<p>And see: <a href="https://chemistry.stackexchange.com/questions/7467/is-pure-water-very-corrosive" rel="nofollow">https://chemistry.stackexchange.com/questions/7467/is-pure-w...</a><p>It's hard when a supposedly reliable news place writes things that are not true, but that's the world we live in. I guess technically they are just quoting stories they were told.<p>(My personal pet peeve is a news source that made everyone think you can't leave eggs outside the fridge if they were washed, (as they are in the US). This is not true, but "there's a news source".)</p>

<p>You aren't finding anything because it is not true. Ultra pure water does not become some kind of solvent.<p>It's the reverse problem: because the water is so pure it easily gets contaminated by minor things. So all the equipment has to be carefully cleaned.</p>

<p>The idea is that we give up the land tax revenues in exchange for the services the non-profit provides. (And of course the government does not decide which services are useful or not, the people do.)<p>One thing I might agree with is land tax for non-profits that charge fees for services, as opposed to those who work off of donations. I think that would fix the issue without destroying non-profits.</p>

<p>A profit for who? It's a non-profit. If the sale netted extra money it goes back to the people who donated, or to another non-profit.</p>

<p>There are almost no places where a housing shortage is due to a lack of land. Housing shortages have all sorts of reasons, from constructions cost, to zoning, to restrictions on what can be built, but it's virtually never a lack of land.<p>And parking is a productive use - they have services once a week, and parking means people can come to the service. That's the definition of productive use. Something does not need to be used 24/7 to be productive.</p>

<p>The idea with IMAP is multiple clients can work with your email - for example your desktop and your phone can both see the same messages and manipulate them, even offline.<p>Gmail basically is IMAP with a couple extras, and your desktop (via a browser) and your phone (via a dedicated app) can both see the same messages. Only the phone can work offline though, because there is little demand for a dedicated desktop email client, it's always via a browser. But Google could easily make such a thing if they wanted.</p>
