220v isn't achieved via two phases; we get 110v out of a single phase by center tapping the transformer. The center tap wire is called the "neutral" and is at ground potential, and then the two "hot" wires. There's 110v between the neutral and either one of the hots, and the hots are 220v apart. It's still one phase.

Note I used 110/220v here and 120/240 above. peak-to-peak, root-mean-square, ask an actual electrician, I'm just an asshole on the internet.

Some of those belong to the person in the background.

Honest answer: Induction stoves aren't shit in the US. They don't run at a lower voltage because our homes are wired for 240V same as Europe.

Honest explanation: The American power grid closely remembles anyone else's, we've got the big long distance power lines up on those big pylons that transmit power in the megavolts, those get stepped down at substations to a dozen kilovolts to snake into neighborhoods, and then those pole mounted transformers step it down to 240V to make the couple hundred foot trip from the pole to a few houses. The difference is that in America, the transformer is connected to the house with three wires, not two. The third wire is a center tap, so you have the two outer wires and a center wire.

Measure the voltage between the outer two wires, you find 240V. Measure between the center wire and either of the outer two, you find 120V.

Most of the normal outlets throughout an American home or business are wired between one of the outers and the center, to deliver 120V. But, we routinely wire some circuits across the two outer wires for 240V, we even have special plugs for this to make sure you don't plug a 120V appliance into a 240V outlet. Things such as electric water heaters, HVAC units, clothes dryers, electric car chargers and electric stoves are indeed wired for 240V here.

Induction cooktops took on a low reputation in the US because early models were hilariously expensive (Westinghouse was selling an induction range in the 70's for $1500, that's about $10,000 in today's money) and not particularly reliable. Another factor was all the trendy cookware from the 60's on. CorningWare and Pyrex (ceramic and borosilicate glass) was huge in the 70's, Calphalon (anodized aluminum) and Revere Ware (high-nickel stainless steel) was on all the wedding registries in the 80's, and solid copper was big in the early 90's. None of which work on induction stoves. Which means, for decades, Americans perceived induction ranges as gimmicky crap that required "special" cookware, that to buy into an induction range would require throwing away all your pots and pans. Americans continued preferring resistive coil electric or natural gas stoves.

Well, we arrived into the 21st century, teflon-coated steel and tri-ply stainless pans come into vogue, Corning stops making consumer ceramic and glass products, Revere changes their stainless formula, and now we find that most cookware on the market is induction compatible. Induction stoves are the fastest growing market segment in kitchen appliances in the US, everybody wants one.

Wow, your mom sucks. Get her out of your life.

I have only ever seen the phrase "don't chase, attract" used by women to peer pressure each other out of actively participating in dating. Reminding each other to never express enthusiastic consent.

"Playing hard to get" is taking that line of thought to the logical extreme. "Want men to want you more? Always turn them down!"

It's the opposite side of the "women want assholes" coin, it's an incorrect premise taken to an extreme.

I assert that terror is terror.

I think video games are good for terror. Subnautica for example, reaper leviathans are terrifying, but not horrifying. You encounter a reaper, and it's a spike in adrenaline, but you don't lay in bed that night staring at the ceiling about it.

Abstract: I burned a pair of audio CDs three days ago for listening to in my cars. Two (nearly) identical discs, one for each car. I have largely moved away from optical discs but am making an effort to re-embrace them.

Full text: So when I went to build my PC, I wanted a Fractal Meshify 2 Mini case. I built my cousin's PC in one, I wanted one too, but they had apparently been discontinued. I wound up with a Pop Air Mini case instead, which in many ways isn't as nice, but it does feature a pair of 5 1/4" bays hidden behind a magnetic panel at the front of the PSU basement.

One of my little projects was to install one of those multi-format card readers and an old optical drive there, and I got it done a few days ago. I have a USB optical drive, in fact a couple of them, but an internal one is just a nicer thing to deal with. It is my understanding that no one is actually manufacturing those external optical drives anymore; that the ones you see on Amazon with god knows what branding are old laptop drives of whatever spec stuffed into a new case with a USB controller. They're flaky, janky, and flimsy. Plus there's never anywhere to put them; they come with short little cables so they're invariably hard to plug in. So instead I ganked a blu-ray reader/DVD writer drive out of an old Dell I have lying around and installed that, and man is it nicer.

My inaugural project was to make a couple of audio CDs for the car. This project involved little to no piracy; all of the audio came from legitimately purchased CDs that I bought as directly from the band as I could. I want to fund the artists, not the sniveling IP hoarders. So I've got discs now that have my favorite 25 out of ~120 tracks I bought from them in my cars. I ripped the discs to FLACs the second I had them and have been listening to them on my phone, my precious originals safely stored in a CD rack.

I also bought a new spindle of CD-Rs, which is also getting harder to do. The ones I bought have inkjet printable labels. And it just so happens my old inkjet printer has a disc printing feature that I've yet to use. So I tried it out. Getting this particular printer going in Linux for more than basic features is a no-go; CUPS+Gutenprint is available for at least a thousand makes and models of Epson printers including the models above and below mine in the range, but specifically not mine. I chose to take that personally, but in the meantime I have discs to print. Funnily enough the printer can do this without a PC at all; it has a feature specifically for printing JPGs onto discs, and another feature that I have to assume is designed specifically for piracy:

My Epson XP-830 Expression Premium "Small In One" printer has a built-in feature to copy a CD from the scanner bed to the disc tray. That is, put a CD label side down on the scanner glass, put a printable CD-R on the disc tray, and it will figure it out and copy it. I can think of no purpose for that other than to hand out copies of Now That's What I Call Music 7 or Windows Vista Home Premium to all your high school friends. It's useless for things like "File Archives 2011" or "Iron Butterfly Beach Party Mix" but it's a very user friendly counterfeiting workflow.

So mostly I installed this optical drive for reading rather than writing. I can see a future where I replace this drive with an M-disc burner; I keep threatening to start a Youtube channel, and that might be how I archive video footage, but...I don't know.

 

A lot of the laws of physics I've studied, like Boyle's Law and Charles' Law, describe the behavior of "An ideal confined gas."

I've had to tell several flight students to unlearn what they've learned about that in the meteorology chapter, because, for example, in a confined gas, increasing the temperature causes an increase in pressure while the density stays the same. In the Earth's atmosphere, increasing temperature does nothing to the pressure and decreases the density. Because the Earth's atmosphere isn't "confined," there's no lid, the air is relatively free to change volume. Heat the entire planet up and the atmosphere will just get a little taller.

But, I think, even if we put a magical vacuum tight shell around the planet 200 miles up, making the volume finite, I think the atmosphere would still act like an unconfined gas, because 1. it's so vast that it never homogenizes, parcels of different temperatures, pressures and moisture content take days to slosh across the available space, and 2. the Earth's gravity will cause a pressure gradient; most of the air is at the bottom and if you heat it up, it may not change volume but the pressure at the top will increase.

So I guess there has to be an upper limit to the volume and/or mass of air that can be "confined" and it's somewhere below planetary scale.

 

Something written had to exist in order to be read, so writing is at least a second older than reading.

 

I have a 3DConnexion Spacemouse. I bought it, and use it, for CAD work, but I'm drunk enough to think it'd be fun to play Satisfactory with. What do you think I'd need to do to map it to a controller or something? Am I gonna have to fuck around with the Python library? It's been awhile since I've fucked around with a Python library.

So here's the state of things right now:

I've got a Synology NAS with stuff like my movie collection stored on it. I think at some point I'll move my music collection up there, too. It's an ARM powered 2-bay thing, I'm not particularly interested in using any of Synology's software, and there's some stuff that won't run on that box because it's ARM instead of x86. I don't really have a "server" box running.

A few years ago I bought a "commercial TV" aka one that doesn't have Roku or whatever. For awhile, I ran OSMC (basically Debian Kodi) on a Raspberry Pi, which...I had enough problems with that it's unlivable. I'd rather just not have a television than continue to use OSMC.

In the meantime, I built a new gaming PC for my desk, the old machine (which happens to be in a Fractal Node 202 case so it already looks like a TiVo) has been moved into the living room. It's a Ryzen 3600/GeForce GTX-1080 machine with a bit over a terabyte of SSD and 16GB of RAM. It's still kicking bubblegum and chewing ass. Yes, it idles at a greater power draw than the Pi pulls at full steam, but it'll spend most of its time asleep, we'll be okay.

I'm currently still using Mint Cinnamon on it. Which is a hilariously unusable home theater OS. Plus I have my desktop (a Ryzen 7700/Radeon 7900GRE machine running Fedora KDE) and my phone (A Galaxy S10e) that I sometimes watch media on. Some questions:

  • Why does VLC error out when trying to play mp4s stored on my NAS? Is it because SMB is Microsoft fucksewage that doesn't actually work? Because that's my working hypothesis.

  • I have so little information on what Plex/Jellyfin even are, I gather Plex is at least semi-commercial while Jellyfin is the open source but worse option. These may or may not have a server component that has to run on a server-like box, which I don't and won't have.

  • On the client side, I don't know if they take the place of a DE the way Kodi does, or if it's a separate app, or if you'd have to exit Plex or Jellyfin to use something like Steam, or if Steam Big Picture mode would work as a media center, but can it get to Youtube...

Is there anything out there that works better than throwing my TV away and forgetting about it?

 

I finally caught a lunar eclipse. like five of them I missed due to weather, it's clear tonight.

 

Did a lot of things like emptying the bathroom trash can, got rid of some packaging that was holding nearly nothing, put some stuff in some drawers, folded one load of laundry and loaded another. The place is technically better in a way that isn't apparent.

 

Sometimes gravity pulls her wrong.

 

Like, would Hephaestus be the god of magnetos, distributors and capacitor discharge ignition systems? Or does that count as lightning and thus be Zeus' problem? Is Oden the god of whiskey because it necessarily must be made in oak barrels, or being booze would that fall under Dionysus? Is Mercury the god of SMS?

 

I'll go first: r/kitty. One of the hundred grillion cat subs back on Reddit, the culture in this one was you posted a cat picture, and the only word allowed in the title or in any comments or replies was "Kitty."

Someone is using that subreddit for covert communications, I just know it. Either on the level of "if u/PM_me_your_nostrils posts an orange cat, we attack at dawn!" or there's some steganography going on with the pictures, but that subreddit was too stupid to be as active as it was.
