The breakdown of probability regarding what actually kills people was really interesting to read. I think he is spot on about handling the mundane disasters like power outages before worrying about the end of the world. It is just good common sense to have insurance and savings.
canpan•1h ago
For finance, I find interesting the other way around. You see many fire types preparing TOO MUCH. Obviously you should not live paycheck to paycheck. But if you prepare for a 3% return fire, wasting years, your chance of dying early is the much bigger worry than running out of money.
verelo•1h ago
Great time to see this here. This morning I, in Canada, reached out to a friend in Ukraine and asked "I might be over-reacting, but what do you wish you knew before the war started?"

His response was "You're not over reacting, you might be under-reacting, worst case you end up with some cool new toys. Best case, you're more prepared than anyone else."

So yeah, here we are. Good article to add to my research.

wackget•1h ago
Well, don't leave us hanging. What did they say?
cryptoegorophy•1h ago
Smartest thing would've been - move out of Ukraine. Shit went sideways long before borders got closed. There were plenty of red flags.
verelo•1h ago
Funny, not funny, this friend and I met up in early 2020 and had a beer down the road. He was telling me he'd rented his apartment in Liviv and was moving here next week. He had to go home to get some things, hand over the unit, and then he'd be back.

Next week was the pandemic, borders closed. He never left, and now he /still/ cant.

They are proud people who want to defend their country.
crystal_revenge•38m ago
The world we're headed for there is no "other place" to escape to. Many people's view of survival during collapse ultimately assumes the existence of a fairly large "safe haven" space for which they just need to survive until they get there.
verelo•1h ago
LOL sorry, here's the list:

Generator 5kw - you want something with a higher duty cycle than you need so it can run for extended periods

Diesel storage for back of a truck - 330 Gallon (nice to have, after a week or two supply lines got fixed)

Diesel - for said tank

Medical supplies - IFAK kit (NAR is a good vendor). Bleeding control & dexamethasone.

Solar power - 1-5kwh. We still get 10-15 hrs a day on the grid, but this would be ideal.

Batteries - minimum 5+kwh storage

Network cable - 300m+ to start. I'm shocked how many times I need a cable and cant get any.

Hand pumps or small electric pump for different fuels and water

Ice auger - gas, but electric ideally, large / long drill bit 2" works too if you have a drill and smaller pipes?

Take a first aid course - MARCH protocol

Iodine pills not important - way bigger issues if you're resorting to that.

Get a rifle - not good for military but useful against looters and other unarmed crazy people

Get familiar with remote detonation with drones, these are what we use to set off the molotovs: <https://www.amazon.co.uk/100-30cm-Electric-Fireworks-Igniter...>

Edit: formatting

cryptoegorophy•1h ago
is the last point correct? "Get familiar with remote detonation with drones, these are what we use to set off the molotovs:" seems off for this list, like way off and more on military/offence side of type of thing?

and why would you need a 300m+ ethernet cable in a disaster?

snypher•55m ago
Depending on the scale of the disaster you may not want your Starlink on your bedroom roof.
verelo•51m ago
Totally valid use case for sure, and we discussed this because I do have a Starlink dish, but honestly, in a conflict with the US...I don't think a) I'd want to use starlink and b) i'd expect it to work.
verelo•52m ago
In his case i didn't actually bother asking about the cat6 because i already had a huge reel in my garage, but I can think of cases such a remotely mounting satellite dish' and maybe connecting buildings to each other.

The molotov didn't seem out of range for me honestly. Firstly because I know he was one of the first people flying drones for defence, and now they've been mass producing their own for a few years. I have to admit, it seems pretty rational to want to fight back in any way possible.

tosapple•46m ago
I was thinking the other day that ALL drones SHOULD be considered LIVE explosives. It's probably never a good idea to handle one if you're not trained.
verelo•37m ago
Last march i was at SxSw and the police drones over head were a first for me. I was in this large crowd of people, and thought "yeah i dont like this". How do i know they're not just some bad actors drone with red and blue lights?

I think my exposure to casual discussions of how to arm drones with my Ukrainian friend, and the videos we've all seen on Reddit about drones in Ukraine, have really made their presence feel unwelcome.

tosapple•30m ago
I think in the US legally they have to have a beacon while flying now, but my thought the other day was about them being parked/down.
dlcarrier•28m ago
If you have a solar panels, a battery, and generator, it would be good idea to figure out how to hook them all together. Using the generator near its full output, to charge the battery, will use far less fuel than idling it all day.

Even if things are bad enough for iodine pills, they are only really needed for children. Once you hit your mid teens, your thyroid is fully developed and not pulling in enough iodine to worry about radioactive isotopes.

mynameisash•11m ago
I assume the iodine is about water treatment and not radiation?
nidnogg•1h ago
Cool new toys! I like it. I've recently been thinking of branching into more water sports such as rowing, ocean swimming and the like to have a better shot at surviving out at sea. Hopefully I've gotten some mountains covered by now.
omoikane•1h ago
I see this page pop up with some regularity, and unfortunately the disasters mentioned within seem to become more and more likely each time I read it. Maybe I am just growing more pessimistic, but COVID-19 felt like yesterday and all the large scale layoffs certainly don't inspire confidence.

I renewed my home insurance policy recently and there was one clause along the lines of coverage being excluded for war/insurrection/rebellion/military related reasons. Previously I would have thought nothing of it. These days I read these exclusion clauses in the same spirit as the "problem space" sections listed in this disaster planning doc.

acidburnNSA•1h ago
Lots of good stuff in here. One thing to note about building off-grid self-sufficient abodes for "Problem space #3: The zombie apocalypse" is that the roving hordes of warlord-run gangs will consider finding those to be the ultimate booty. This point is made quite clearly in Six Minutes to Winter, the new book about nuclear war by Mark Lynas. As much as I always wanted a sweet prepper cave, the idea has now soured on me a bit.
potsandpans•22m ago
i've not read the book, but i've thought about this on and off for a while.

the common trope of a mad max style wasteland where there are roaming barbarians and everyone is in a state of disorganized chaos is imo overstated. a hobbesian fantasy/wet dream.

humans tend to be self organizing and (mostly) altruistic in the face of disaster. we have plenty examples of this: fukishima, the boston bombing, ongoing ukrainian conflict, syrian conflict.

that's not to say that scoundrels do not exist. times of chaos create space for predators to take advantage of people. it happens more frequently at greater scale. there will be plenty of untethered folks with some form of military training.

similarly, the idea that you could simply ride out a long term disaster in a prepper cave is (again coached in an imho) mostly a fantasy. most people simply need community to survive.

fear of warlord run gangs shouldn't dissuade you from having a small stockpile of goods to survive. if they exist, and you meet they'll probably chop your head off regardless.

the most sensible thing to do is prepare within reason and build a community of people around you that can rely on you and vice verse.

tharkun__•16m ago
That's one of the issues with these if you ask me.

Either you're a hermit, that really can build that hermit cave in the mountains, far off and all the guns they're stockpiling won't really be used.

Or you're way too close to civilization coz you have an actual family and they'd never do / care about any of that "crazy stuff".

And if you're that close to civilization, it's all about who's got the larger stockpile and larger amount of armed thugs. Are you really gonna fight off 30 guys with AR-15s with a family of four, two of which are children to protect your stash of food and gas and generator(s)?

The only way your "prepping alone" is gonna help you is the hermit case, far far out of sight or if it's "not all that bad anyway".

Build stable societies.
BLKNSLVR•50m ago
But be prepared for the society you live in to vote for an obviously, significantly destabilising leader...
django77•41m ago
Some societies can be stable for a while, but all of them eventually become unstable, collapse, and make room for new ones.
DetectDefect•39m ago
Care to name any examples?
crystal_revenge•34m ago
Stable societies fundamentally require increasingly large energy inputs. What we're seeing happening right now, in a large part, is due to a system whose complexity has exceed the available energy required to sustain it.

The idea that what we're seeing is because "too many people voted for the wrong guy" fails to recognize the larger condition for which all of this is merely emergent phenomena. We no longer have the resources to sustain the society we life in so it begins to uncomfortably revert to lower energy states in ways we haven't seen in a long time.

pugworthy•1h ago
I've got a few high tech friends (and myself) that have slowly become more and more of the mindset to be self sufficient.

Two things probably have made me initially think more about it. First, the predictions of a major subduction earthquake here in Oregon, and knowing I'd be somewhat on my own for a while after that. And the other thing is Burning Man, which has taught me about self sufficiency and how one can actually have their cake and eat it too now and then.

Then there are guns. I've got two, and both are very much antiques. One a Krag 30-40 from 1908, the other a 1946 Springfield M1903. Both military issue, bolt action, and beautifully crafted. And both quite functional, powerful, and deadly items.

Why do I have guns? First because they are historical (used to work on a WW2 era video game). Then there's in theory hunting if I had to. Then there's protection. I can't deny that yes, I would consider using them if me and mine were truly threatened.

My only rule of thumb for any of this is never shall it say "Tactical" in the product name or the seller. Nor shall it have camo pattern.

dlcarrier•36m ago
One of those things that I have trouble mentally placing in the correct time period is the standardization of the cartridges that we still use today. When they were developed, tractors were still using metal tires and blood type testing for transfusions didn't exist yet. Living on the West coast usually meant that you had to be self sufficient. Some of my ancestors at the time lived in Idaho in a hole they dug in the ground, that they put a roof over. They had another similar dugout that they filled with ice blocks during the winter, to sell in the summer for some income. Most of them were sustenance farmers. One of my great grandparents had multiple acres in Van Nuys to grow enough food and raise enough rabbits to live off of. That land would be worth millions now, but back then it was what you needed to get by. Being rich would mean you had nicer clothes and a bigger house and servants and didn't have to grow your own food, but even the rich rarely had electric power, and when they did it was only routed to lamp sockets.
RRWagner•16m ago
Do many people think that with their single assault rifle or other weap9n, that they would successfully defend against one or more truckloads of vandals looking to steal whatever they have stored up "self-sufficiently"? History seems to indicate that in the absence of law, those with the most people inside a fortified structure and position are the most likely to survive.
mrexroad•8m ago
Those folks tend to have a confounding number of firearms, rather than just one. Not that it necessarily shifts the eventual outcome to your scenario.
retrocog•7m ago
Its always good to be prepared materially, physically, and psychologically. The best preps are not supplies, but relationships. Social credit matters more, IMHO, than anything else when it comes to long emergencies.
