The author of this article seems quite politically driven like the mods on Wikipedia, and created it disingenuously. I feel it's an attempt to overwhelm the readers through massive amounts of text so that they are too tired to see what's being said at the beginning and end are completely unrelated.
Phd in Critical Big Data (aka Critical Race Theory for archiving) and undergrad in women studies. Had her funding cut by Trump because someone had the idea that tax-payer money shouldn't be funding "research" into how archiving has racism and oppression.
That's because the author in question is the one who had their funding cut.
Their research revolves around "Critical Data Theory" which sounds very stemmy at first, but looking deeper it has nothing to do with stem and is in the sociology department that focuses on oppression. Based on critical theory (remember critical race theory?), they study oppression in how people archive historical records.
Another professor pretending to be of a technical nature, yet in reality is just writing op-eds. No different than a NYT hit piece.
Go look at their undergrad degree and google their field. It tries everything in its power to attempt to look like a technical field, while just being another DEI course.
I work for a U.S. company that makes ergonomic 3D printed keyboards. We design specifically for the individual user's hand. Almost all the keyboard shells (the 3d files) are designed custom for the individual.
Labor is pretty cheap. It takes on average about 2 hours to build a keyboard. If there are no issues, it takes 1 hour. That costs about $25 total on average for labor.
The main cost is the 3d printed shells. We print PLA ourselves for cheap, but we outsource Nylon and Resin to China. These can cost anywhere from $150 to $200 for the entire thing.
The next highest cost are the PCBs. Our connectors, PCB columns for the switches, trackball PCBs, and the "brain" PCB, where all the logic processing happens, end up costing over $100-$150 total.
The total cost to build them ends up being anywhere from $250 (the absolute minimum barebones keyboard) to $400 for higher end boards.
When I hear or say K, T, or Ch, I hear a higher pitch frequency being used than B, M, L (which sounds like lower frequencies).
Humans have a psychoacoustic effect that makes higher pitch sounds perceived as being louder.
When somethting has a louder intial sound, but the transient sound is about the same, it makes it feel more snappy (like a snare, versus a kick). This is reminiscent of a jagged edge.
Good thing this doesn't apply to fair use, which allows you to have an offline copy for yourself (assuming it isn't for commercial purposes, and you can make your own offline copy).
"The discovery suggests that wireless energy, like that from Wi-Fi and mobile signals, could cause antiferromagnets to produce electricity that might one day be tapped to power portable electronic devices."
I think this is even a more interesting application.
Another Dell tomfoolery: their laptops advertised with 100w usb-c charging actually does only 60w charging, unless you buy Dell's superduper usb-c charger. Regardless if you have usb p.d 3.0 or higher.
