No, it doesn't. It's a fair comment about external arms supply intensifying conflicts, without apportioning blame.

[flagged]

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 included their own, such as the Great Purge, which happened before Holodomor. It was about resisting Sovietism.

God bless the people on Stackexchange who actually answer the question that is asked instead of scolding you for your idea being bad or being pedantic about the way you phrased your question. Yes, I want to use jQuery. No, I may not be in an active war zone.

You also see this in system administration circles/SRE quite a bit. And I mean, that's one of the important skills you have to learn in the operative trade: You should push for clean solutions. You shouldn't use clothesline to transfer power. You shouldn't use an EOL OS to run systems.

But as much as you push, sometimes you need to put on the rubber boots and gloves going up to your shoulders and figure out a somewhat safe way to run some Windows XP based machine controller in an environment. Or wrangle some Java 1.6 thing back into function. Or figure out the least security reduction to support some old system not supporting modern crypto.

And yeah, usually the idea is to put trusted isolation layers around the dumb idea we have to deal with, as the water hose suggested in the article.

Daily reminder that online, someone well-off lying in bed with a nice bowl of soup can be talking with someone homeless in a third-world country with no chance of improvement whatsoever. Hopefully the OP in SE is not the latter and it's just a temporary situation, especially if they're in Ukraine and Ukraine wins.

The OP is from Sudan.

Ukraine has been impressively fast in rebuilding critical infrastructure after Russian cruise missile strikes. It also helps that many of the Ukrainian men that have gone back to Ukraine are construction workers, electricians etc. Many of them are even working under the risk of Russian double-tap strikes.

Steel is about 10 times less conductive than copper which is why it is rarely used for cabling. Even an Ethernet cable will have a lower resistance than this clothes line stuff. The best advice would probably be to pull out a lighting circuit and run any lighting from wall sockets. Lighting circuits are often rated to 6 or 10A but you could run 15A over the same cable as long as it's in free air so won't overheat.

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.

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?

I’ve found that having a charged, exposed cable laying around will start to rust within about 6 months. This is from cheap phone cables so it being copper-coated instead of full copper is likely.

I’ve also heard of cathodic protection or electronic rust proofing doing the opposite though? Maybe it has to do with moving charges vs static charges? Or ground a cable preventing rust vs charging it accelerates rust?

It's like we're living in a parallel reality in 1st world countries

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.

Fly to Brazil, take a cab around Central Sao Paulo. Your understanding of the world is warped by the safety and availability of goods. It's incredible when you get in places where the state doesn't function at let's say 50% of what we get in the first world. It's one hell of a learning experience.

I was recently in northern Vietnam. You could spend an hour having a simple conversation via Google Translate. Made me realize there are still big chunks of the world where you can't take basic literacy for granted in 2023, even of people in their 30s.

50% of Americans cannot read at a highschool level.

There's a substantial difference between the amount of time and guidance an individual can spend with a single question when you're on a site that gets 3.9k questions per day and one that gets 21 (stats from https://stackexchange.com/sites#questionsperday )

Thats a reason to not engage if you dont have time. It is not a reason to sit down and dismiss away questions or type out why you wont tell them.

Today, most people who are doing curation of Stack Overflow are not engaging with a question at all. They down vote and move on as any attempt to help is seen as rude... and just down voting and moving on is also seen by some as rude... and not doing anything and having a question get ignored is also seen as rude or frustrating.

As there are many fewer people answering questions compared to the rate of questions being asked the overall "is stack overflow rude or not" is a "yes." But engagement numbers are up as people keep asking them.

I have said it before I think, that I am sure Stack Overflow absolutely can, if they want to, reduce the amount of low quality questions they get.

The problems Stack Overflow has seems to me to be very much self inflicted, caused by the decision to optimize for political games instead of optimizing for solving problems.

Steel is bad as an electrical conductor as its much higher than copper internal resistance would waste a lot of power. I don't know if the military still use wired field telephones, but in case they do, the field phone wire is excellent. It won't sustain lots of current, but if you're OK with a few amps, then that cable is sturdy, water and oil resistant and it has both copper and steel core, the former working as good electrical conductors and the latter making it extremely hard to break. It's also very good for building low cost emergency long wire antennas, dipoles, etc.
