It's not privilege, millions of people have died defending the right to not be invaded by an asshole neighbor. Don't forget the price people have paid. Some places seem to be less interested in that, because they want to invade their neighbor, and we should be aggressively hostile to that very concept, and anyone who espouses the belief.

Unless you or your family were the ones that fought, it is privilege. Privilege isn’t a “bad word,” either - it’s okay to have privilege. But acknowledging it’s existence goes a long way toward building humility and understanding the situation of others who don’t have it.

Define family. Because most Americans are descendants of war veterans.

> It isn't designed for steel but some kind of protection must be done at connections or arcing will be a major risk. Not so much arcing but resistance between the terminal and the wire will increase as a coating of oxide builds up between the two. Eventually the resistance is high enough that dangerous amounts of heat will build up and ignite wire insulation or other flammable materials. What usually happens, is the…

You don't really need "rosin flux", the idea is to remove oxidation, chloridric acid is what was used for tin soldering, "saturated" with zinc. https://en.wikipedia.org/wiki/Zinc_chloride#As_a_metallurgic... Though I have no idea if either can be found locally.

> Though I have no idea if either can be found locally.

Which is specifically why I mentioned rosin. Though any acid could likely be used so citric acid or something that could work as well.

The ability for you to find a good question to answer is in part based on the work that other people do in down voting and closing questions. If you go to the triage queue - those are questions that are being prevented from showing up. If you go through "newest questions" there are often questions there that can't be reasonably answered without more work to figure out what the problem is. As I write this, there's a q…

> Ultimately, SO is suffering from issues of scale without the corresponding tooling to enable people who are trying to answer to find interesting questions more easily. Yes, that seems like a reasonable take. I suppose in my imagined ideal reality, people simply don't answer questions that are not asked well, or that don't interest them for any other reason, rather than actively body-slamming those questions. If thi…

The difficulty that SO has had trouble with is the "then the site suffers." How do you measure that? They want to run some A/B test that allows the corresponding measurement to show that things are better with a change.

However, it feels that the only way that they've really accepted measuring it from a sales / marketing view (as that's what brings in the revenue) is the "engagement" metric. People signing up, asking questions, and accessing the site.

Better moderation tools which would result in fewer but higher quality questions on the site shows up in that measurement of engagement as "worse".

---

The part that you encountered is that "if the question isn't answerable, it should be closed." That in turn feeds other parts of the system. Users are more likely to update their questions if they are closed rather than if they're left open. Other people who answer questions (but rarely engage in fixing up questions) are less likely to click on questions that are closed. People that routinely ask poor questions that get closed start getting automated warnings about their question quality before they ask a question and end up with a question ban if that behavior persists. A closed question without answers or edits to improve it get automatically deleted after 30 days.

Without going in and commenting on a question and then spending time with the person ("why don't you just answer it if you think you know the answer rather than commenting? If you don't like it just don't read it." is something I've seen many times) closing the question is a way to suggest improvements to the question without exposing yourself to users who not infrequently then pursue a... negative engagement with the person trying to help them ask a better question.

I can see about digging more (it's been a long time since I went looking for it) but somewhere on one of the meta sites was a post about the different interactions and the "engagement" metric for new users asking a first question.

The best way to not have them ask a second question is to completely ignore their question - no votes, no comments, no answers. Closing a question results in more people asking a second question that is positively received than having no interaction.

(late edit - did the digging - https://meta.stackexchange.com/questions/216683/what-happens... )

Who are we to weigh the consequences to the poster of a lack of electricity against risk created by jury rigging? And specifically, to make that choice for them? Caveat hacker.

This isn't even a hacker, though! This is a person who isn't capable of doing extremely basic electrical calculations. It'd be a totally different topic if it was a person who I thought fully appreciated the danger of what they're doing. If you can't calculate the voltage drop over a length of cable you should not be wiring your own deadly AC voltages. I'm willing to die on that hill.

This is a metaphorical hill you're willing to metaphorically and not literally die on? How brave.

The Stack Overflow poster is on a metaphorical hill in a literal warzone to literally die on. They're trying to hack together AC power the best they can to make their home in Sudan livable. That's some serious hacking! So what if they don't know V=IR?

The risks of using steel cable for power are going to be corrosion/rust. The primary way this will cause problems is around connections, but long term it is also an issue away from connections. At connections, corrosion can cause the wire to become loose, something like ox-gard can be used to delay this significantly. It isn't designed for steel but some kind of protection must be done at connections or arcing will b…

Out of curiosity, does electron flow influence oxidation speed at all? Or is its speed purely a consequence of temperature + environmental gases?

"Out of curiosity, does electron flow influence oxidation speed at all?"

Oxidation (and reduction) are literally electron flows.

Oxidation is a loss of electrons and reduction is a gain of electrons.

Since the oxidizing material is the anode in this (oxidation "circuit") you can connect a "sacrificial anode" to the material you want to preserve and the electrons will flow from that instead of the (material you want to save).

We have sacrificial anodes connected to our underground propane tank:

... which means a bag of magnesium does all the rusting instead of the tank they are connected to.

I mean, so what? If one of my ancestors fought in a war defending their/my country's freedom, I don't get to claim credit for what they did. I am privileged that those ancestors made the sacrifice they did and don't have to fight in a war myself.

It's unclear if he means Alternating Current or Air Conditioning with AC. I hope it's the former, because the latter needs kilowatts, not the 270 W they have. "Concrete" can also mean "the cement based building material" or "specific", as in "this specific building needs power to be habitable, because " (pumping drinking water for example, which is mentioned). The comment "because Russia and America are busy in Ukrai…

What else would they need power for? Heating and cooling are the only appliances I can think of that would be necessary for habitability.

The device they're asking the question from ;)

We are. I was an exchange student in Ukraine in high school and the town I lived in periodically gets shelled now… we live immensely privileged and comfortable lives. This is not a bad thing, it’s great, but we should try to make everyone else’s life as good instead of hoarding our privileges.

It's not privilege, millions of people have died defending the right to not be invaded by an asshole neighbor. Don't forget the price people have paid. Some places seem to be less interested in that, because they want to invade their neighbor, and we should be aggressively hostile to that very concept, and anyone who espouses the belief.

> It's not privilege, millions of people have died defending the right to not be invaded by an asshole neighbor.

Yes, and benefiting from that -- without having had to fight in those conflicts -- is a privilege.

Unless the ethernet cable is made from copper clad steel, which is sometimes used for ethernet cables and very common for consumer grade phone and RF cables.

I've heard of copper clad aluminum but never copper clad steel Ethernet.

Well, iirc the classic coax for cable TV is that; they may use solid copper when using it with an LNB to power said LNB.

Again, it's been said already, but you are reading into something that isn't there. Providing arms to a side that didn't have them is going to intensify the conflict. That's just the absolute cold hard reality of the situation. That's all that was being pointed out. Linking to early soviet era atrocities shows just how much you are reaching. The soviets were not discriminatory in who they killed, and very often inclu…

> The soviets were not discriminatory in who they killed, and very often included their own

Well, Ukrainians don't think so, and then Russians of today have even more unambiguous genocidal intentions towards them. Paraphrasing a (Russian) classic – these genocides have never happened before and yet again.

Also, Wagners torture mobilized Russian soldiers just as gleefully as Ukrainian ones, but that does not mean that the genocidal intent is absolved, it just means that its the Russian way of doing things.
