  • And when it’s really unusable as a desktop anymore, it can become a headless PiHole server. There’s always a use. Back in 2005 I was using an old Pentium MMX laptop with a broken screen as a Wifi access point/router. I even bought a two-way 2.4Ghz amplifier to hang off the laptop’s PCMCIA wifi card to boost it throughout the apartment.




  • I learned how a kernel actually loads a program and switches between them by using timer interrupts and interrupt vectors that point to specific locations in memory to resume execution from. Not specifically Linux related, but I’m trying to learn more computer science, and it just clicked for me two weeks ago. I’ve been programming microcontrollers for ten years, but those are monolithic programs, and while I knew what interrupts were and have used them, I never understood how an OS actually runs multiple things while staying in control. Now I do. About time I understood a core concept of these machines that have been here all 42 years of my life.

    It’s one of those “aha!” moments like when I realized classes and structs are just data types like any other in C++ when I was starting off programming and can be used like them. OOP became fun after that.







  • I get that. I was just saying why it might tick some people off. My idea of a good OS is one that you don’t even notice while using it. It just sits in the background doing its thing and you don’t have to think about whether you’re using KDE, Gnome, or whatever, because it never makes itself known and you just happily use your programs.






  • They sure love them some Java. It’d be nice if they focused more on C/C++/Rust, you know, actual bare metal system languages that make you think about memory management.

    Edit: I used to have a roommate who was studying compsci and they were making him program a PIC18F microcontroller on a development board in assembly. It was kinda fun because while he wasn’t using it, I’d have fun with it just programming normal C and making all the blinkenlights and gizmo peripherals on his board do shit, while he was struggling to even read a sensor.
