Somewhere between “I want to play sci-fi video games all day,” “I want to invent everything ever,” and “I want to go on a 6-month backpacking trip in the wilderness.”
I do something similar (though less secure) for general purpose passwords; I have a couple of common “base” passwords that are decently secure that I commit to memory. Then for each website/service, I pick a pattern based on the name/url (maybe something like the first two and last three characters of the url), and append them to one of my “base” passwords, so each site gets a unique password, but I only have to remember a couple of them + the pattern
Is there a distro you recommend? I’ve toyed around with Tails, but the lack of persistence and forcing all traffic through Tor instead of a VPN (I guess the whole point of Tails) is too inconvenient for daily use.
TIL that Unicode includes hieroglyphs lol
I fucking love how nerdy this place is
Watch him as he codes
Not to be “that guy” on top of you being “that guy,” but it’s not unheard of to completely redirect a dammed river with a chute spillway. I’m gonna pretend the spillway exits that mountain to the right of what we can see lol
For sure, there’s no community as large and passionate as religion. BUT there are other communities that are centered around goodwill to others, living a better life…some of them even have chanting, if you feel like you’d be missing that part lol.
Those communities usually involve doing work though (volunteering, performing, teaching, etc.) while you can just show up to church and kinda pay attention, and you’re in.
I feel like, at their core, most religions boil down to two things, for most people:
Personally, I prefer to define my own purpose, live a more “dynamic” lifestyle than is traditional, think critically, and question authority. Doesn’t make me “better” than religious folks, in fact they’re probably overall happier than I am. But I can’t imagine living that way, regardless of whether or not I believe in a magical sky Santa who can’t decide whether he loves us unconditionally or whether or not he’s actually omnipotent.
“pools are perfect for holding water”
Oh no, it totally matters. In the case of a receiving tank, rated for 300 psi internal pressure vs 1 atm external. The limiting factor there would be tensile strength, or how well the material resists being pulled apart. Sticking it underwater with 1 atm internal would test a combination of compressive and tensile strength, but more compressive (if it were a perfect sphere, it would just be compressive). Good news is, steel is a relatively good choice for both.
Which was one of the complaints about the material choice for the Titan; Carbon fiber has high tensile strength, but low compressive strength. The strength of the hull had more to do with the resin than the carbon fiber itself. In fact, I’d be curious to know if there was even a benefit to using carbon fiber over regular fiberglass. That and it’s hard to inspect for fatigue compared to other materials like steel.
Case and point: Deepsea Challenger, the sub used by James Cameron to go to the bottom of the Marianas Trench, had a pressure hull made of steel.
I mean, today, entirely seriously, I spent about an hour looking at used prices for air receivers for this exact purpose. You can totally get 250 gallon tanks rated to 300 psi that are about the right size to fit one person and all the electrical components inside. Cut off one end and replace it with an acrylic/poly-carbonate dome, add a keel, ballast system, and thrusters on the outside, cover it all with a fairing, and you’re good to go!
I’m thinking I could prototype a functional sub rated to 150 m for around $10k. Totally worth it.
Trust me, I’m an engineer as well lol
I can’t wait until we get bots that verge on gaining sentience, like good-ole u/bobby-b-bot
Welcome to the internet! So exciting to have someone who’s brand new to how things work here.
it’s used by military forces all around the world
Yeah, wired Xbox controllers, not wireless Logitech crap. You willing to entrust your life to a working Bluetooth connection?
Certainly no need to reinvent the wheel. But maybe use something stronger than dental floss to secure it to the axle.
God, there’s a joke in there about 404 (famous drum sequencer, often referenced for its kick sample), but I just can’t find it
Open 20 posts at a time in new tabs and immediately close them, like me? Lol still some improvements to be made with the feed sorting algorithms
It could be mounted externally, separate from other systems, and it would be fairly trivial to implement a strictly mechanical means of activating it from inside the vessel. All that would be needed is to open the valve on the external pressure vessel.
If you’re referring to getting out once you’re on the surface…hell of a lot easier for rescue crews to find you and do that if you’ve got a huge orange inflatable holding you at the surface, rather than however many thousands of feet underwater.
I’ve been toying around with some design concepts for a DIY submarine for like a decade now. The first thing I thought about, right after “how do I control it going up/down” was “what do I do when that system fails, and I need to ascend in an emergency?” My thought was to have some scuba tanks attached to deployable salvage lift bags, so even if my ballasts were completely screwed, I could still ascend.
If there’s not something analogous to that on board the Titan, I’d be shocked at their stupidity; It seems incredibly foolhardy to intentionally go somewhere that no rescue vehicle can recover you, without secondary and tertiary systems in place to rescue yourself.

I’m a tinkerer as well, but I’m at a point in my life where I need to prioritize my tinkering haha. Like buying stir-fry takeout (Windows/MacOS), cooking it by buying a pre-packaged bag (packaged mainstream Linux distro), or starting from scratch, experimenting with literally everything from chopping technique to cooking temp for each ingredient, until you realize you’re missing an ingredient you need, then you have to go back to the store (Arch lol).
