No, you need printer ink but refillable cartridges are a thing. Not all printers make it easy, or even practical depending on how physically rights-managed they are.

The ink is where the money is for printer sales, the printers themselves last basically forever if you treat them nice but ink needs replacing all the time and it's expensive as poo poo.

Not entirely true.

When I worked in Dell Business Sales a decade ago, most poo poo sold with a goal of 15% Margin (Profit). The majority of machines were closer to 5-10% margin.

Printers? Each one was a least 70% margin. If you sold those, it could save your week or month. Even the $3k Office Beast was over 70% margin. They were made as cheaply as possible, marked up double or triple, then treated as a lovely way to keep you buying the ink.

Can someone help me to understand the fluid dynamics inside a stovetop espresso pot?

In particular I'm trying to understand why the coffee 'bulb' (I'm not sure what it should be called - the bit that you put the actual ground coffee into) has such a long stem extending down into the boiling chamber.

It seems to me that the steam would mostly get stuck in the upper space of the boiling chamber with only a small amount escaping through the stem and up past the coffee. Clearly I'm wrong because the thing works, but what is the mechanism that makes it happen correctly?

Edit: I guess it's gotta be something to do with pressure, right? As the pressure of the steam in the boiling chamber increases, something happens to regulate the pressure differential between the upper and lower parts of the assembly?

Just get Enrique to write out your documents with a fountain pen, much easier.

But no, fountain pen ink has a bunch of stuff in it that clog or grit, which doesn't matter for pens but really does for tiny nozzles and stuff.

Is there an online tool or service that will let someone easily record audio from a phone/tablet device and transcribe it automatically, ideally organizing everything by date?

Basically, my grandfather wants to write down some thoughts but can't type easily because of poor eyesight and finger dexterity. He has an Android tablet that he uses to Skype with us. So it could be an app, but there's no way for us to install it remotely and easily train how to use it. So I'm thinking more like a web service with one giant record button.

As I think about it, it should be pretty trivial with today's technologies, but I don't want to DIY it unless it really doesn't exist.
Edit: I can't physically come over to set anything up so it has to be as simple to use as possible.

It's a difference between consumer and business markets.

Maybe margins could be 50% on the $50 inkjet too but they're definitely not making much actual profit on those.

Apple's voice transcription is also pretty good. You can transcribe in notes, onenote, or any similar such app with cloud syncing to make things even easier. You can do this on any apple device whether it be a computer, tablet, or phone.

Without opening the app store, I'm certain there has to be actual transcription apps that will have features like timestamping and such but they might cost you a couple bucks.

At least for consumer models, there's a price cut somewhere along the line. I used to sell printers; they were priced at cost and sold at a significant loss when discounted.

Same for low to mid-end laptops and consumer electronics in general. The business model was to get customers in the door and buy add-ons.

This may have changed with the gradual death of big-box stores and transition to online sales. Although I haven't seen significant price differences since then. It's notable that laptops containing 2000 and 3000 series Nvidia gpus are significantly cheaper than pre-built pcs although that may be due to lessened supply chain difficulties as crypto miners don't use laptop hardware.

So far that does seem the easiest. I'll give it a shot myself and we'll see, worst case I could probably get someone to set it up for him.

Yeah there are many options on the PC and I could set something up but that's not a possibility unfortunately. Probably should've made it more clear but I can't physically come over and set anything up as he's in Ukraine and I can't come over because, you know.

Why would the steam get trapped? It takes up like sixteen hundred times as much volume as the liquid water it comes from. It either goes somewhere, or you’ve created a bomb.

The reason you haven’t created a bomb is there is somewhere to go: through the stem. The lower chamber only needs a pressure of like point three PSI above ambient to lift a column of water up the few inches of the stem.



Here’s video of a moka pot via neutron imaging, if that helps.

Awesome, thank you.

I didn't know the part about 1600 times more volume! That definitely helps explain it. Also I was fixating on steam rising through the stem and not water being pushed up through by the pressure in the chamber, it all makes sense now.

Great video too, thanks. Although I found the cutting back to the visibly unchanged pot just sitting on the stove really funny.

You don't want the steam, it makes terrible tasting coffee. You want to push liquid high pressure water through your coffee. That is why the inlet is on the bottom. And that is also why you should take the pot from the stove once you get the pure steam noise.

There's usually a pressure valve about 2/3rds of the way up the Moka pot. If you put too much water in, the interior portion of the pressure valve will be immersed. Then there's a potential for creating a bomb. I know nothing about physics though, so I don't know how likely it is. Somebody smarter can calculate the likelihood of it exploding. It probably varies depending on the size of the Moka pot.

The upper part of moka pots only have enough space for filling up to the bottom of the pressure valve or a little under, so there isn't any reason to pour more water in anyways.

This is really neat, thanks!

Shot in the dark: are you using the same name for your 5ghz and 2.4ghz wifi? Maybe the printer gets confused because it isn't vaccinated and doesn't speak 5ghz. You could try setting up a dedicated 2.4ghz network.
Or just stop printing stuff and use a PADD.

I work out daily, doing about two hours of high intensity stationary biking.

I've gone through more than a couple gym mats that rest beneath the bike to protect my hardwood floors. But I need something bigger, as even with towels laid out I'm sweating enough for it to run over the edges and onto the hardwood floor. The current mat size is 72 by 36 inches.

Interlocking gym mat tiles would be perfect. I have a leg disability, which makes it very hard to me to move big stuff around, like mats and carpets. But I have a specific worry - Do the interlocking sections allow sweat to seep through? Or do they effectively block it when fit together?

Also, any tips or tricks for dealing with huge amounts of sweat in a tiny home gym space that doesn't involve laying out a bunch of towels would be welcome.

We use foam floor pieces like that for our kids' playroom, and they've blocked pee and cat barf pretty well, I guess. I do still open them up and clean between them when that happens though. Not sure if that's something you're going to want to do if you sweat over a large portion of the floor.

I'd use a multi-layered approach -- foam on top of a roll of plastic or something similar, which rests on the floor. That way, anything that does get past the foam will be blocked by the second layer.

This is a good idea but could lead to a sweat buildup beneath it and foam will eventually rot, depending on how much sweat and whatever. Instead, put the foam against the floor (or plastic, then foam) and then put something like a rug you can exercise on or a rubber mat on top of the foam so it's all one piece you can easily clean/roll up but you get the padding effect of the foam.

of the appropriate size. Put down the tray, then the bike, surround bike with towels, use a rod to pick up towels and wash them. Tray catches excess from getting on the floor, but the system gets cleaned without you having to bend down. Just a thought.

What is the name of the rhetorical device when you mention bad things about your opponent by saying you won't mention them? It's something I remember from Cicero in high school. E.g. 'I won't bring up the fact that my opponents beats his wife because that has no bearing on this discussion, and neither will I mention his fondness for drink, because that too would be improper to bring up in this case' etc.

Similarly, is there a latin or greek phrase for the device of 'damning with faint praise'?
