@lauriewired Mel is the patron saint of the bare metal era, we’ve gained massive velocity through abstractions, but we’re definitely losing that granular intuition of how the hardware actually breathes. There’s a unique kind of respect for someone who treats the machine like a tailored

Wow so Bitwarden CLI got hacked for about 90 minutes yesterday, through a very novel method. This malicious actor has hatred for LLMs (same Queen or King).

So they were using a worm introduced by the novel method to target keys associated with LLMs and other valuable keys. Very scary and sophisticated.

The normal version of Bitwarden wasn't affected, and of course the malicious altered version was depreciated so it can't spread. Still fascinating in a horrifying way.

Look at this thing I've made!

It is actually a transpiler from the weird c-like syntax for bitllevel operations that exists in my brain to code that the LuaJIT interpreter actually understands and can evaluate, displayed in a well-aligned manner right inside the text editor.

Bueno, ya hay drivers y de todo (Que no hice yo)... lo que necesito ahora es ver como reemplazo todo esto de forma casera.

Estos SoCs hacen el siguiente boot sequence.

  • BROM carga un SPL (Secondary Program Loader / Grabador de programa secundario)
  • SPL carga la parte principal de un U-Boot, este se llama "U-Boot proper" (La razón de por que se separa en dos es por cuestiones de memoria, hay poca memoria SRAM y se necesita cargar una parte que sea el módulo encargado de gestionar la DRAM que son 32/64MB)
  • Resto de U-Boot.

    • Conceptualmente SPL carga el mismo código que U-Boot pero restringido, solo los drivers necesarios y una version recortada de esos drivers, todo para meterlo en la SRAM.

    A mi parecer, son conceptualmente equivalentes estos terminos.

    BROM = BIOS
    SPL = Bootstrap
    U-Boot = Bootloader //Este es literalmente así jajajaja, no es "equivalente" U-boot es un bootloader, solo que un bootstrap y un bootloader tienen diferencias.

    Al margen de eso, dejo estos artículos de utilidad.
