Usually missing wifi firmware can be solved without internet this way: - look into dmesg. It will tell you which firmware file is missing. - go (on another machine) to packages.debian.org, enter the filename into "Search the contents o

I use one of these two, whichever is better for a given case: - install it using debootstrap from some live system ( https://www.system-rescue.org/ , or Debian on a usb stick). Internet works in this live system, so I can ins

Yes, however, there is little practical advantage in this, if nobody knows about it and so nobody turns it off.

Notice, for example, that Thunderbird is sending file names and SHA-256 hashes when you open most (e.g. .pdf) attachments, in the clear, to Google. This seems worse to me (in the Apple case, the information is revealed only if enough files

More and more services require Android/iOS, either with Google services, or they even detect and block users with rooted devices/custom firmware such as LineageOS (for example Revolut). So far, one can go without them, with some i

Do you have any sources regarding the effect of pulses, e.g. in animal studies? Most materials I have found are dealing with average/CW power. (I work with weather radars, so I was doing some research recently to find out what I should

Horn antennas have radiation pattern tens of degrees wide, so it's difficult to target one room across the street. I'm not sure intersecting a few of them helps, maybe by a factor of two or so. Back of the envelope math: per Wikip

Longer wavelengths require huge antennas to concentrate the energy at a distance. It would be probably very difficult to perform this attack. I also think that such energy density with relatively low frequency (~3 GHz) would disturb operati

The hibernate image is much smaller than RAM: disk cache is dropped and the image is compressed. It of course depends on your use-case (how much incompressible data you have in RAM), but you can expect about one third to one half of RAM siz

I would like to read about a better design that should be implemented instead - can you share some links? I cannot imagine how compatibility can be achieved given that address fields in IPv4 are fixed 32-bit.

You can find lots of stories about PayPal freezing accounts for random reasons. With well-known projects this usually resolves by public shaming, but I guess this can be impossible to solve for a small seller in a non-US/non-West-Europ

In the Czech Republic, most fines (for traffic offenses but also pretty much anything else) are defined by range, with the span 2x to 10x.

What total mileage do you have? In my experience, it will start skipping on some gears after 7000 or maybe 10000 km and then you need to change the entire drivetrain, because it got destroyer by the heavily worn-out chain. Learning to fix t
