Man here. Female friends key to my not feeling lonely. Couldn't identify less with men who only see hanging out with men as key to not feeling lonely, which is what this app seems to offer. Seems like the target market for this is lonely lads, when lad culture is driving male loneliness. But hey, I guess some men, even in the West where this app is targeted, really just feel uncomfortable making friends who are women. Open yourself up, lads.
CTAN is the central repository for all TeX packages, it's the natural link to give. If you want to see examples it's as easy as clicking on the relevant package name (eg XCharter) and then click 'Package documentation' which will request the relevant pdf. TeX outputs into PDF so it's the natural medium for demonstrating and documenting things. It's got nothing to do with not 'living in the current century'.
They used freely available NASA data to map Russian and Ukrainian electronic warfare systems. The jammers used leak into the 1.4 GHz spectrum, which is suppose to be silent, and does so which sufficient power that you can be pretty sure it's man made.
So if you're looking for an intersting target, you could do worse than those lit up areas.
Small correction: the jammers used are specifically targeting the L-band, because it is used for navigation and satellite communications.
Normally ground transmitters in this band are using just a couple watts or less, so they don’t significantly impact the readings of a satellite looking at a large area on the earth, but a jammer uses a lot more power and can be noticed.
There is a satellite that listens to solar radiation reflected off the earth to tell different things like ocean salinity. That particular frequency is also used in warfare. This satellite can be used to find areas where electronic countermeasures are in place.
There's a satellite that's measuring ground moisture by looking for radiation in a specific frequency. Some jammers in Ukraine (devices that send noise on radio to make communications impossible for other people) emit radiation in this frequency which makes it visible when looking at the data from the satellite.
Waiting for the Show HN browser extension that reformats all HN posts to fit into a shorts frame. Then rather than just displaying the text, it puts it in an annoying animated font. Maybe even adds an AI character to read it to you
There’s a long history of coffee as a social force - namely because the alternative was usually beer, and you can imagine the wild swing in a population going from beer to coffee as their recreational beverage of choice. Coffee’s been implicated in the surge of “enlightenment” thinking, as well as the development of the financial industry (and, due to the former, also has a long history of catching the ire of kings and rulers.)
