200miles/8hours of skating straight means an average speed of 25 miles an hour.

Ambitious, considering the average speed of a skateboarder is closer to 10 miles an hour, but it could be possible if he was extremely fit, had unbreakable bones, and the US was a flat plane for 3000 miles like this guy thought.

I was wondering how the scientists went from proposing a planet that was 1.5 to 2 times the size of earth, to proposing it being 5-10 times the size of earth.

You Should Really Considering Explaining Acronyms Before Posting, obviously.

A remote command from some random phone to reboot does sound like the a wonderful vector for malware, though

They think not masturbating will give them anything from higher testosterone, better focus, or to a higher IQ.

They think masturbation makes you weaker in every way.

This is of course patently false, and all basically rises from an old athlete myth that sex during training will reduce your progress. Which these dorks then took to an extreme by saying any ejaculation will reduce progress in physical and mental training. Because we all know that the key to success is stored in the balls.

I remember doing the bear grills one, and one of the choices was to jump over a ravine, or walk over it using a fallen tree as a bridge.

Being the hiker I am, the obvious choice of walk around it being missing kind of annoyed me, but I chose the tree option.

Bear died.

So I got to go back and pick the jump over option, which was apparently the right one.

Who the fuck does running jumps over a 15 foot deep ravine.

I never bothered with the choose your own adventure things again. When the correct choice is just not available and the next logical choice just means an instant loss, you don’t have a very fun game

If you’re a government, you can pretty much put anything in a rocket fairing and call it a reconnaissance satellite.

The only warning that actually has to be given is that a rocket is being launched, so you don’t accidentally trigger WW3 by setting off launch detection satellites without warning. After it’s in space, no one can really tell what was in the fairing. Could be a spy satellite, could be navigation. Could just be a box with a bunch of little rockets in it, designed to slam into whatever you want at ridiculous speed.

But it’s way more likely that this was just Boeing having a tiny leak in a propellant tank, or a bad thruster and as soon as the concentration of propellant and oxidizer got high enough, it triggered a detonation. They certainly have a history of not leak testing their shit: airplanes falling apart, space capsules with leaky thrusters, and now a blown up satellite point more towards incompetence than malice.

Peppers take a good idea, having extra supplies and tools for an emergency, and take it to 11.

I’m not a prepper, but I did read my local government’s disaster preparedness list and have everything on it that applies to my family. I keep 3 days or so of extra, shelf stable food in the house; bought a home water cooler and keep an extra jug of water that I rotate when we use the one in the machine so that we have a few days of clean water at all times, which is way more practical and safe than a camping water jug that will sit and stagnate in the basement; I have a battery “generator” that I keep topped up with a solar panel because we have a sewage ejector pump and a sump pump to stop the basement from flooding in bad weather; and I have good first aid kits for the house and cars.

The only thing not on my local government list are the emergency car kits, which is really just a basic vehicle toolkit, jumpstart kit, flares, sweater and space blanket, all in a cheap bag that lives on top of the spare tire.

I don’t live in the most disaster prone area, but we do get tornados and nasty thunderstorms that knock out power for a day or 3. We don’t exactly have the lights on when that happens, but we do have food, water, a non flooded basement, and even some heat in the winter, and both cars have something to keep you warm while you either fix the car or wait for the tow truck.

I kind of understand peppers, because planning all of this out after we lost power a few years ago for 4 days in fall was interesting, and there was just so much shit the internet was saying I needed: weeks or months of dried beans and rice, a generator for the whole house, enough guns and ammo to ward off a small army, etc. my local government list was hard to find compared to all of the forums and YouTube videos, but I’m glad I found it, it’s sensible and if spread out over months, very affordable. I highly, highly recommend you poke around your local government website for their natural disaster page, they’ll have resources of who to contact if you need help, and what you should have on hand. If it’s not on your city’s page, try your county or state government. One of them should have a page about disasters and how to prepare for them.

There was a big idea a couple decades ago that corporations were going to copyright natural genes and sell them for massive profits to other biotech companies that could use them to make cure for diseases and other things.

Michael Crichton wrote a few books about it, pretty good reads.

They did do the gene copyright thing in the real world, but it turns out that doing anything with a random gene is pretty hard and the genome isn’t just something you can copy paste a gene into and have it cure aids or cancer, so no one wanted to buy genetic sequences that they would then need to do a whole bunch of work on anyway to make it useful.

Pretty much all 23andMe did was increase the size of the Law Enforcement dna database by letting cops send in samples of suspects and get back their family members info. Of course the company said that was very naughty, but no one got into real trouble for it. And now 23andMe owns a lot of other people’s genetic code, and it’s not worth the hard drives it’s stored on.

I could actually see this being useful for dangerous working environments like steelworks or inside nuclear facilities. As long as the control system is on a separate intranet that’s properly air gapped.

You should still pay the operator their full wage though. The human still needs all of the technical knowledge to do the job, you’re just removing most of the physical risk.

That’s an extremely bold assumption.

The space shuttle was designed originally to be rapidly reusable, but its shortest turn around time was still measured in weeks, not days.

And its main engines only produced water as a by product, no soot or carbon deposits to worry about.

There’s a bunch of hacked chalice dungeons you can join that essentially give you unlimited blood echoes.

Oh we have generics all over the place.

The problem is that large drug companies abuse our patent systems to keep their drugs exclusive for longer than should be allowed.

Look at EPI pens. The drug is just Adrenaline, you can get a vial of that anywhere as long as you have a prescription. But the EPI pen mechanism itself is patented. So no other manufacturer can sell an easy to use, pre measured dose of Adrenaline without violating the patent. That’s why EPI pens cost hundreds of dollars instead of the 20 bucks they probably actually cost to produce. And you need that mechanism, because no one with a throat that’s closing is going to be able to calmly pull out and ampule or vial, measure the right dose into a syringe, and get it into their system before they pass out from anaphylaxis.

To orbit the moon, a space craft needs to move at about 1.5 km/s, or 3300 miles per hour.

So any landing starts with you going at 1.5 km/s and needs to end at the moons surface when you reach about 0 meters per second.

If anything goes wrong with your engines while you slow down, you smack into the moon at either near orbital speeds, or at fighter jet speeds. The window for having an engine failure and being slow enough to survive is so narrow that it might as well not exist.

That’s why Apollo used pressure fed, self igniting engines. As long as 2 valves opened, you had an engine. And Apollo landers had a totally separate ascent engine that worked exactly the same way, so if the landing engine failed, they could just drop the landing stage and return to orbit at practically any time during the descent. They even had a whole procedure of what to do if the ascent engine didn’t light when they were supposed to leave. Everything from jump starting the engine like a car with a dead battery, to physically getting access to the valves and manually opening them.

I hate the current plan for Artemis. I hate that in 55 years, we’ve only managed to make shit more complicated. The current plan is for a vehicle with no abort capability to ignite its 3 turbo pumped, liquid methane fueled engines at least 4 times to get from low earth orbit to the moons surface, with days between ignitions.

A capability that has never been shown to work or even exist in any capacity. Turbo pumps are finally machined pieces of engineering that need to behave exactly right, or they turn a rocket into either a bomb, or a giant tube that can’t move. And the current plan for Artemis calls for these finely crafted pieces of machinery to be subjected to the harsh environment of both space where they’ll sit for at least a week, and multiple ignitions, where they’re subjected to ridiculous temperatures and pressures.

Absolutely ridiculous. We never left an astronaut on the moon in the 60s and 70s, but by god are they trying to open the first graveyard on the moon these days.

If your primary means of housing came out of your ass, you’d probably embrace the assless slacks too

Semi drivers require a commercial license, and special training. They’re monitored way more closely than your average American driver.

And side mirrors only let you see what’s behind the car to the sides and at a distance, not what’s immediately behind the car. I don’t want some idiot in his $80K battering ram to roll over me because I happened to walk behind his death trap and he couldn’t be bothered to wait for the rear view camera to come up.

Not being able to see what’s immediately behind the vehicle is a safety hazard, especially in suburban areas or parking lots where most people are reversing out of a space with other people walking around.

The Cybertruck has no rear view mirror when the back cover is down.

So any reversing requires the use of the backup camera.

The car also accelerates really fast, and weighs 7,000 pounds.

It’s also an $80,000+ car that was preordered by a lot of people without test driving it. So it’s primary driver is someone who makes risky and impulsive decisions.

So a really fast, heavy car that can’t see behind it without a reverse camera, driven by impulsive people makes me think the reverse camera should definitely come up really fast.

It’s not about converting the car.

I have a 2009 Chevy with an automatic transmission. I’m order to convert it to electric, the ECU would have to be replaced so the car knows when to shift to a higher gear without a combustion engine.

Because of environmental reasons, ECUs are pretty tightly controlled by the government. I don’t know if any company even exists that can sell an aftermarket ECU. There’s plenty that can hack or reprogram ECUs, but even that is becoming increasingly regulated and legally questionable.

I would love to convert my car to an electric, but it’s an automatic so I’d have to spend as much as a new car to convert it.

A drop in ECU replacement and motor/battery would be great, but I doubt the auto industry or the government is going to allow the sale of third party drop in ECUs.
