    I’ve seen someone do something slightly like this with a greenhouse. It had a large tank of water in the middle. It was black, so it absorbed sunlight during the day, heating the water, and then that kept the temperature up at night.

    I think it also had something to do with an aquaponics setup? Like there were either fish in the tank, or in a “pond,” and fish shit water would be cycled out to the plants because fertilizer?



  • but since thw moon is smaller than the earth how does sunlight leak like that?

    1. I believe this is a partial eclipse, or the beginning or end of a full eclipse. The Sun isn’t all the way behind the Earth, it’s poking out to the bottom-right.

    2. The glowing ring around the entire disc of the Earth is the atmosphere, which acts as a lens. The Moon has essentially no atmosphere, so when the Moon eclipses the Sun we on Earth see a sharp-edged dark disc encroach over the Sun until totality which blocks enough of the light from the Sun’s photosphere that we can see the wispy corona. The Earth’s atmosphere means you will see a bright ring around the planet throughout the entire eclipse even into totality as sunlight is refracted around the planet toward the Moon. We can see this from Earth during Lunar eclipses; as the Moon passes into Earth’s shadow, we see a large soft-edged semi-circular shadow pass over the face. Once all direct sunlight is off of the Lunar surface, your eyes adjust and the entire Moon’s disc seems to glow a dull red. Why red? Something something air, something something refraction, something something chromatic abberation.

    Is the variance in distance between the earth and moon that large?

    The distance from the Earth to the Moon is 0.25%, 1/400th, of the distance to the Sun. As you note, the Sun happens to be 400 times larger than the Moon, so viewed from Earth the two bodies coincidentally appear very close in size. The eclipse above was taken from about a quarter million miles further away than the solar eclipses you may have seen in person. The Earth-Moon barycenter is inside the Earth’s volume, so we’ll call that insignificant. If anything, from this vantage point the Sun should appear very slightly smaller than it does from Earth, as the Moon is farther away. This is essentially insignificant as they’re already tiny in the sky. Because your brain is made of monkey meat which processes the sky as a dome 100 feet tall and 1000 feet wide, you perceive them both as closer and larger than they are. You could cover the Sun or Moon’s disc by holding a pea at arm’s length.

    During what we on Earth call a Solar eclipse, the Moon casts a small shadow the size of a European nation or American car dealership that moves quickly across the face of the Earth. Anyone standing still sees totality for about 5 minutes. The Earth’s shadow is much wider, the entire moon fits in Earth’s umbra with room to spare, which is why the entire moon goes dark red.

    Viewed from the Moon’s surface, a solar eclipse would be between 2 and 4 hours of dim, ruddy twilight lit only by a firey halo of Earth’s atmosphere surrounded by the Sun’s corona. Your eyes would adjust to the dark enough to make out stars if you looked in most other directions.











  • What you’ve got there is a panel pilot bit.

    Imagine you’re building a vanity. You make the countertop out of plywood, cut a rectangular hole for the sink, and then put laminate over it. Now your sheet of laminate is covering up the sink hole, you need to cut it out. In the home shop, it might occur to you to get out a drill, punch a 5/8 or 3/4" hole, then you can stick your ball bearing flush trim bit through that hole and then cut out the laminate as a template routing operation.

    Now imagine you work in a cabinet shop and you’ve got 50 vanities to make today. You don’t have time to keep switching between your drill and your router, so you use this bit. It’s a flush trim bit, the smooth area near the tip is a template guide, and the point is so that it can plunge itself into the work without a separate drilling operation.


  • Well…

    Microcomputers had joysticks before they had Microsoft. On the PC platform with the 15 pin game port, a 4 axis (XYZ + throttle) and 8 button plus hat switch form factor arose by the late 90’s such as the Microsoft Sidewinder and Logitech Wingman series. Later models made the transition to USB, there were a couple attempts at force feedback about the time the game industry shifted.

    In the early 2000s, flight sims like the Janes series, Microsoft Flight Simulator etc. and other vehicle sim games like Descent and Mechwarrior faded away in favor of first person shooters like Half Life 2 and MMORPGs like World of Warcraft which are best controlled by mouse and keybaord. Interestingly enough, PC games designed for joysticks like Mechwarrior and Crimson Skies moved to consoles to be played with controllers; both saw their final entries on Xbox 360.

    Microsoft discontinued the Sidewinder series in 2003. In late 2005 they released a Windows driver for the Xbox 360 controller along with Xinput, making the Xbox 360 controller the de facto standard for a PC game pad. This arrangement has remained more or less intact to the present day, with Microsoft adding support for the Xbox One controller to Windows 10 in 2015, though 360 controller support remains.

    tl;dr: The standard issue Xbox controller has been the first party supported gamepad on PC for 20 years.

    Logitech produces the cheap Player Two ones you use to pilot billionaire crushing submarines. Valve tried with their original Steam Controller, which was kinda weird and had niche appeal. More recently the likes of Gravis have tried? But the average unwashed mass is going to walk into Best Buy and pick up an Xbox controller, or use the one that he already owns for his Xbox.





  • The problem I have with the Matrix sequels…1. they’re too far up their own ass. The original was a little up its own ass but it was up the part of its own ass that mattered for the story it was telling. Reloaded and Revelations are up their whole ass. “Love is a word.” 🙄 2. The original is a very straightforward hero’s journey in which deciding to answer the call is the ultimate key to the hero’s power. The sequels are about fate and inevitability and how basically no decision can ever matter. So we’re sorry to have bothered you.
