  • 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. Similar to an antenna, but only works in close proximity.

    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.

    Companies left and right will start creating EULAs with forced arbitration clauses for all kinds of crazy things… Shit like “Being in the general vicinity of one of our buildings, you agree with our license terms”. Or “saying the name of our company, you agree with our EULA”. Or “By being alive, you agree to our EULA”.




  • 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.




  • Make a plan. Think about how much storage you need, whether you need redundancy and backups, and what server applications you need to run.

    Here you also need to consider how much time you want to spend on maintenance. Premade solutions like Synology are set and forget. Using NAS operating systems mean having to do regular updates. Using just Linux is also an option if you want full control and are confortabile with the command line, but it’s more work.

    Then step 2 is getting the hardware.

    My recommended route, if you want to spend the least amount of money, is to get a 2nd hand PC, preferably not pre-built (dells and hps have proprietary parts like power supplies). A 4 core cpu from the last 10 years should be fine, and 16gb of RAM is more than enough for most applications. SFFs or MiniPCs might be ok for nvme SSDs only, but if you want hard drives, get one that has enough HDD bays. Depending on what you find, you might need to replace a few things, like the power supply or case.

    Servers are good and reliable and have nice features, like network management, redundant NICs, redundant power supplies, but are usually pretty noisy.


  • I have mixed feelings about Mir and Unity. Having competition is a good thing. If we only had gnome, Linux would be far less interesting. But at the same time, they could have spent the effort trying to improve Wayland and Gnome, and they would have made a significant difference.

    But snaps being forced upon me, they can fuck right off. I don’t need my browser in a semifunctional container, when it worked perfectly before. And i hate that they made mount barely unusable.
