  • The tape head is basically a small and really sensitive electromagnet. Magnetized tape creates small disturbances in the magnetic signal. Amplify those disturbances and you get sound.

    This also works in reverse. Feed an audio signal through the electromagnet, and the electromagnet will create the disturbances in whatever is next to it. You can do this to record to a tape, or you can do this to pass sound to another tape head, which is how these aux cassettes work.

    You can build one yourself really easily. Just take the tape head from a broken player and solder to an aux cable. Take a cassette, remove the tape, and put the tape head in the middle portion so it comes into contact with the player tape head.


  • Amazon is on my shit list and will not buy any products from them ever again. They are one of the worst monopolist mega corporations. They treat their employees like slaves, are anti-repair, anti-consumer.

    I gifted an older Kindle to my sister, and the screen broke (out of warranty). I contacted Amazon about it, and they basically said they don’t make replacement parts and don’t service the kindles, they can only give me a small discount for buying a new one.

    I looked up a guide on doing it myself, and even if I find a replacement screen, it’s really difficult. The screen is glued with a strong adhesive. The entire device looks very cheaply built and deliberately made really difficult to repair.













  • Antivirus software for Linux also has kernel access. You can’t intercept OS operations like opening files or launching executables without kernel access. And some of the companies I worked at also required antivirus software on Linux servers.

    You can absolutely run Windows without an anti-virus, it has plenty of security features built-in.

    It’s all a matter of trust. Do you trust your engineers to properly configure machines to be secure and not run exes from dubious sources, or do you trust a cybersecurity company to do it for you? Anti-virus software nowadays is more about restricting users from doing stupid shit.
