In the simplest analogy, it's just the TV rabbit ears with two wires in opposite directions, except much longer wires, because the frequencies are lower and therefore the wavelength is larger. Those classic rabbit ears are effectively

Kernel drivers, too. Especially the DMA buffers for devices that don’t support scatter gather: if you don’t allocate them at driver startup, you might not be able to find enough free contiguous regions later. Although maybe that’s not as bi

For small amounts of text, another simple way is to paste it into the Run dialog (Winkey-R) and then copy it back out again. Works well for turning URLs into plain text and removing the editor formatting from function names before pasting i

Just FYI that the link to the page about the case against ultrasonic humidifiers is broken; it's missing the / after the domain. I tried leaving a comment on the page, but even after creating a dummy profile it wouldn't accep

Not just the first day, but the very first run. They cheaped out and didn't build a bypass for a 30 MPH curve on an otherwise 80 MPH run. Which, while embarrassing enough, shouldn't have resulted in an accident even if the conduct

As I understand it (and I'm not an expert just curious reader), it's part of what ATSC 3 is fixing by moving to OFDM instead of 8-VSB. Multipath in OFDM leads to some (hopefully few) number of subcarriers fading out, which error c

Charles Poynton has good references on this. His website is very 90s, but his books (a la Digital Video and HD) are the best clearly explained introduction to color science and gamma vs linear light coding that I've ever read. https:&

Kindred souls. About three years ago, I did the same, but with NTSC. In my case I actually built a digitization board that sampled the signal from a composite cable and dumped the raw samples over USB using the Cypress EZ-USB2 chip. I didn&

I'm also about that far away and walked through there last night. It felt more like a summer street fair festival. I also took a few pictures. https://photos.app.goo.gl/UN8RpwWS5TYAY5Nn7

Middle schooler in the mid 90's, sitting in the backseat of the car while parents drove around town on errands. 2 meter ham radio antenna on the roof, with a packet radio modem and black and white power book laptop running off the ciga

If you want to live vicariously through others, various people publish live images of captures over their locations on https://wxtoimgrestored.xyz/gallery/ In particular, being on the west coast I'm fond of watchi

I wonder what signals they actually route out the FMC card. The website doesn't give a lot of information, but it seems like probably just ChipLink which they claim is their serialized TileLink bus protocol. So, you probably wouldn&#x2
