Any tips on best practices in how one can protect homelab rigs from a Carrington level event? Let's say we were given two days notice that the mother of all S4s was inbound. Just switch everything off?
What if one of my homelabs needed 100% uptime to meet my wife's SLA for messaging? Is this able to be protected?
Not much? As I understand it, the major effects are in very long wires. Long wires can have get massive induced currents. But your homelab is unlikely to have long wires or very large loops. Ethernet wires are limited to 100m, and unshielded Ethernet is transformer-isolated to well over 1kV.
Shielded Ethernet could plausibly have issues with induced current on the shield. PoE might be less immune than ordinary Ethernet depending on what you’re doing with it, although well-behaved devices should be isolated. If you have a cable ISP, the cable shield might get toasty, although it’s likely to be grounded close enough to your house that any damage will be upstream.
Your 100% uptime will be tricky if your ISP goes down or you lose power.
AFAIK the risk is for long transmission lines. So your equipment at home is not really in any danger, as long as there is not a major surge on the transmission lines that makes it all the way to your house. If that happens, well, losing the home lab is probably no longer the issue.
Make sure you have a surge protector or ups, in case it makes the power grid go funky. Which you should have anyway.
Also, it could be a convenient excuse to upgrade to fiber internet service if you haven't already. (Yes, excuse. Equipment should have more than good enough isolation to not care.)
Even if you don't have fiber all the way into your house, most cable internet terminates pretty close to the home these days. It kind of has to, since bandwidth has gone way up and as a result they can't put very many subscribers on the same termination system.
We didn't really understand this kind of thing when the Carrington event happened, so nobody knows for sure, but estimates for induced voltage on long conductors are usually something on the order of 20V/km. So for a 5 km long coaxial cable, you're only talking about ~120V of induced potential difference (i.e. the same voltage as a residential plug in the US). When people are analyzing the potential damage from this kind of electromagnetic disturbance (E3 is the term you'll see, based on analysis of nuclear EMP which has other components that you don't see in geomagnetic storms regardless of severity), it's mostly about really long conductors, like on the order of 100km.
The issue is most people don't have a setup that will even care.
Bluetooth lowers audio quality, and very few people have DACs or even phones right 3.5 jacks.
I often imagine an alternate history where Apple kept the jack, maybe added a 4.4... audio quality would be so much higher now.
Think about all the audio engineers who don't even consider higher quality setups. All the bandwidth on earth don't matter if the original master isn't perfect.
Whoa boy. I caught Landman for the first time today because my partner was watching it.
Oil, cigarettes and alcohol were all clearly being pushed and promoted. Pretty sure it was episode four where a women rather matter-of-factly stated that one alcoholic beverage when pregnant was perfectly fine - inso much that it was good because it helped her body generate breast milk. Such a weird statement to shoe-horn into this soap opera.
Coupled with BBT chain smoking the coffin nails, the rampant shit-canning of renewables and incessant self promotion of how large and wonderful the fossil fuel industry is the money behind the show was as subtle as a sledgehammer.
Plus the sexual objectification of women in this show is ludicrous.
I haven't seen Landman, but I have heard of it. My understanding is that all the characters are pretty miserable, but that it nonetheless weirdly glorifies their lifestyles.
I guess it is a bit like François Truffaut's statement that there are no "anti-war films". I imagine if some population segment has chosen to identify with a particular lifestyle (oilman, soldier, gangster, etc.) then it doesn't really matter quite how that lifestyle is portrayed so long as the viewer can make a connection with it.
never heard of this show, I wonder who produces it
oh Paramount
the ones that just decimated CBS News, put talentless propagandist Bari Weiss in charge, and censored a critical report on human rights abuses ordered by POTUS
Nothing.
