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’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).


  • 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









  • Humans are a blight upon the natural world they inhabit

    If you’re so insistent on humans living in an environment counter to their own evolutionary instincts in favor of squeezing every drop of sustainability possible out of the maximum number of human lives (literally forcing humans to live in artificially dense population centers), why are you on the internet? You’re wasting electricity that was either derived from fossil fuels or generated using renewable technologies reliant on rare minerals obtained through strip mining. Not to mention the plastics and metals that went into making the computer/phone you’re using.

    Still wearing clothes? Think of the water being wasted on manufacturing that! What about the resources devoted to growing the plant fibers, raising the livestock, or weaving the plastic fibers? The land that was destroyed and all the native life that was culled to create the farmlands? We should all be forcibly relocated to temperate regions and forced to live in dense nudist colonies.

    Do you exercise? You know how many calories and how much oxygen you waste by doing that? Human physical exertion should be limited to only the bare minimum required to sustain the minimally healthy body weight. You know how much food we’d save if we banned all sports?

    Don’t get me started on the arts. Brain power costs calories too! What a waste. All human creative resources should be pooled together to create the most efficient base of entertainment media possible that enables a livable experience. No more unique languages, everyone will be forced to learn Chinese Mandarin or Spanish, so we can eliminate waste on similar media across languages.

    Obviously MASSIVE /S

    Now I don’t want you to misunderstand, I’m very pro-renewables, rather pro-regulation, and even a bit pro-social-engineering. But literally seizing property and assigning concentrated living quarters to people who’ve owned their homes for generations is some seriously dystopian shit.



  • I feel like, at their core, most religions boil down to two things, for most people:

    • Giving you purpose/security/scapegoats (“I’m living a good life so I can go to heaven,” “the Lord has a plan/is watching over me,” “Satan/sinners/demons tempted me”)
    • Dissuading you from inquisitive, critical thought (out of self-preservation, I’d imagine)

    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.


  • Sooo…100% of future transportation should be done by train or bus? Gonna build an express line out to grannie’s house in the woods of rural upstate LargePlace? Maybe with a few local stops at some hiking trailheads? Can’t forget to add a direct line from there to the closest grocery store two towns away, or maybe granny can just hop on the train to CenterTown and take the connecting bus over to Nowhere’sVille, and grab another train from there. God forbid she wants to visit Aunt Sue in Isolated Harbour. Or maybe we should just seize both their properties and relocate them to Dense Village, which was specifically designed to be public-transit friendly.

    Yeah trains are awesome, and we should utilize them more (especially in the US). But public transit is not the solution to all long-distance travel. So why flat-out reject a theoretical improvement, on the basis that it’s not a literally perfect solution?


  • In the Star Trek universe, if you’re intent on “glassing” a planet, it’s in one of two scenarios:

    1. The planet inhabitants can’t fight off a single star ship, in which case you could just park in orbit and bombard to your heart’s content, with the option of either precision strikes or complete annihilation, without expending anything other than the energy it takes to power the ship.
    2. The inhabitants can fight off a star ship, in which case they likely have the technology to detect such a weapon at sufficient range to intercept/destroy/redirect it, or planetary shielding powerful enough to stop it.

    In the latter case, you could put the effort into adding a cloaking device to the weapon to get around that. But in that case, why not just use a regular cloaked ship to delivery some other payload? There are tons of examples in TNG of narrowly-averted planet-killing disasters only prevented by careful engineering. Probably way easier to actually cause the disaster. Examples include igniting the atmosphere, causing geographic instability/earthquakes/volcanic reactions, exploding the system’s star, crashing a natural moon into the planet, unleashing a biological weapon…




  • 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
