Kagi.com is one of the best services I pay for. I know paying for Internet search seems outrageous because we’ve been accustom to our data being the payment, but I think it’s worth it. The search feature and added stuff really make it very functional plus the no adds or SEO type sites is bonus.
I do. Did you find better results on Google? I’ve used DDG, yandex, qwant, and brave search engine but I really like the add free results and I understand something has to pay for the servers.
Adding to the existing comments, there is also invidious which doesn’t bombard you with adds and if you have a homeserver you can easily host an instance (acts like a frontend to youtube)
Nah, I hired an electrician to handle all that for me. Now if I want electricity all I have to do is stick a plug in a socket, or flip a switch. It’s way more convenient.
My understanding is that if electrical demand starts outstripping supply the sinewave can start getting badly mishapen.
From watching videos about synthesizers and playing with VCV Rack I’ve learned far more about waveforms than I ever did from any electrical education or research
Not exactly. There’s a ratio of RPMs of the drive motor to the specific input of the alternator that generates the correct frequency. It depends on the way the alternator is designed (ie number of poles) that will yield the correct frequency, almost like a gear ratio, that is optimized for efficiency, and power plants have to constantly make slight adjustments to the drive motor speed the keep the frequency exact (usually done automatically within the drive control system).
I’ve never seen frequency be an issue in a residential system, but in theory it could happen.
I don’t know how it’s in 60Hz regions, but here the generators are in 3 phases, 120 degrees apart. The voltage gets transformed to up to 400kV, still in 3 phases, and then down to 400V when it’s distributed to peoples’ homes. Then you can pull 400V 3-phase or 230V 1-phase from your wall.
It’s the same here, though we have varying degrees of transmission and distribution voltages via transformers and regulators. In my area, power comes into our valley from the 500kv lines through the open desert, into the valley at 33kv, and stepped down to 5kv for neighborhood distribution that the single phase 240/120v transformers tap off for the EOL.
More of what I was getting at was that generation is more or less the same across regions. Some external fuel source (whether it’s diesel, natural gas, nuclear, steam, etc) does its thing to drive a rotor that’s connected into an alternator which is essentially an electric motor but instead of the electric motor doing the driving, it’s being driven which generates power, and the RPMs of whatever given fueled drive mechanism are not necessarily 1:1 with the alternator speed.
It used to be common for clocks to be driven directly off the electrical frequency. The US Navel Observatory would call up generator plants and tell them to slow down or speed up a little to make a correction to all the clocks. I’m not sure if that still happens, though.
I’ve heard that trope before, same reason clocks in US schools/govt institutions were always plugged into a wall, hence these. Nowadays, NTP has rendered that obsolete.
From a technical perspective that’s less an issue with people and more an issue with the technology design. People aim for the most comfortable, ergonomic way to hold a smartphone. Which is, you already know it, holding it “vertically” (= long side up, small side sideways). You can easily do it with one hand, whereas you usually need two hands to hold it horizontally. However, it is easily possible to place the camera sensor chip such that it can capture images in widescreen format even when holding the device vertically. Manufacturers usually don’t do this, because they want to allow a more intuitive handling, like “what you see is what you get”. If you hold the phone horizontally, this is directly reflected by a widescreen image and the other way around.
Since people also usually hold their phones vertically when using apps, several platforms, like YouTube for example as well as their content creators, have developed improved support for this. So you can continue mindless scrolling while enjoying more of an image. If the videos / images were in widescreen, the image would be scaled down and details might be missed when holding the device vertically. You would have a lot of black and just a small box in the middle with the images or videos. Probably everyone who reads this will have experienced this.
However, this is of course annoying for people who don’t mind holding the phone horizontally or who are watching videos on a widescreen device like a PC monitor. And that’s not a surprise. We humans evolved to have a larger field of view in horizontal than in vertical direction. We can see more to our sides, but less in up-down directions.
I don’t fear that movies or shows will be recorded in this format (other than for artistic purposes), since that’s a thing where even the comfortable “vertical phone holders” will prefer the wider screen format. But for cheap low effort content or shorter videos and if the target platforms are usually used on smartphones, this is probably a nuisance we have to learn to live with. ;)
