used to love building printers. hated printing parts for printers. It’s all ABS/ASA and those are hard to print, what with the warping and bed/layer adhesion and toxic fumes. I print on a Railcore, which is an absolute beast of a printer and probably more sturdy than your average Voron, but it really wasn’t designed to be fully sealed so anything other than PLA has been a struggle for me.

and you don’t seem to understand…

oh cool it’s a https://en.wikipedia.org/wiki/Triskelion

you layered yourself in blankets the other person is trying to help you make choices about your fabric choices because they affect both your perceived and your actual body temperature and help equalize your comfort between morning and night

they suggested a solution which ACTUALLY FITS YOUR WORLD VIEW of using less electricity or fossil fuels for comfort purposes and you berate them for it.

also, the idea that using energy for climate control is evil is an odd take IMO. not everybody lives in a temperate climate! people would literally die if you just deleted every HVAC system on the planet. and as much as I think it’s silly that Phoenix, AZ exists, the concept of forcibly displacing people from their current home is often frowned upon.

i thought the other guy saying you’d be fun at parties was going a bit far at first, but now I have to agree. There’s no need to be this argumentative or unreasonable and contrarian. unless you’re a misanthrope in which case carry on i suppose?

local Internet user complains about something and guilt trips others for wanting to be comfy when they offer good advice

NO

That last line belongs in a horror novel

Oh hey it’s the biweekly post about English words being silly. Well we’ll see another in about two weeks. Or a few days.

As a human, I cannot comply with your request to “oo, ee, ooh ah ah, ting tang walla walla bing bang.”

please dear God I’ve never asked you for anything before and I’ll never ask for anything again but

Yeah, guess I’m just worried about missing out on cool new communities popping up. Almost every post in all is from a different community.

I had a list of 90 active cat picture subreddits. Wish we had even a fraction of that here.

In my experience, it’s not new. I noticed things were far more hostile than my reddit experience from the moment i got on Lemmy. Maybe it’s because I unsubscribed from all the toxic places on Reddit (i promise they exist) but I browse /all here since it’s too quiet otherwise.

Depends on relative to what.

Connected to the wall: it’s AC (alternating current). half the wave is already negative. You can rectify it backwards, apparently. Or, you can use a split phase transformer.

Connected to a really big battery: big inverter just swaps the leads on the battery really fast.

Hold in your hand: negative charge pump. Magic & momentum.

Haven’t seen conventions mentioned in this thread. Big or small, cons give me the “i don’t belong here” feels

Have you heard of heat rash (miliara rubra)?

It’s not mosquitos, but your description of fiberglass and needles reminds me of this. It feels like each of my pores on my back has a needle in it when it happens.

##PWM Dimming

in digital electronics, it’s hard to send 30% power but easy to send either 0% or 100% power (full off or full on). So instead, to dim a light, we can just turn a light off and on really quickly. If you turn it off 70% of the time, and turn it on 30% of the time, it’ll look like the light is at 30% brightness - if you do it quickly enough. But doing things faster is also difficult, so sometimes it’s fast enough that we can’t perceive it turning on and off, but slow enough that it still causes issues in sensitive people.

Fun fact: if you see LED lights blinking in videos, but not when looking at it in real life, that’s when the PWM dimming frequency doesn’t quite match up with the camera’s shutter speed or framerate. This is known as aliasing: when there’s a slight mismatch in frequency of two evenly-spaced patterns, and combining them results in a new pattern.

Dithering

Not sure exactly what kind of dithering they’re referring to, but I’m going to guess it’s color dithering.

If you only have white and black pieces of paper, but you want to make gray, you might cut them up and arrange them in a checkerboard pattern. If you view it from far enough away, you might perceive it as gray rather than pure black or white.

This is basically what dithering attempts to do: when you can’t mix colors, it’s a method of representing more colors than you actually are able to use by patterning them in certain ways.

Not knowledgeable enough about screens to know why fans are worried about dithering, or why Nintendo might have been considering using it in the first place though.

Ah, I was more referring to how the documentary was very critical of marketing to children, and how people campaigned against that in the years surrounding that.

I didn’t know about his alcoholism, thanks for bringing that to my attention. That said, eating waaay too much fast food and not exercising was pretty much the whole point - he wanted to show how bad that lifestyle was. IMO the only problem there is that he failed to disclose that he was also heavily drinking.

Exactly. Nobody in this thread remembers Super Size Me?
