  • To expand - DirectX is a proprietary Windows solution. Any time you pick it on Linux, it will run through a translation layer

    OpenGL/Vulkan are cross-platform

    OpenGL is to DirectX 11 as Vulkan is to DirectX 12

    Microsoft kept the same branding, but also followed in Vulkans/Metals footsteps of using lower level calls to the hardware. This makes the graphics drivers simpler, and can be way more performant because the CPU doesn’t have to do as much







  • With an HDD, your operating system can (mostly) directly access bits on the magnetic disks, so you can wipe them by just writing 0 to it over and over (historically, there was a paper saying 7 times would make any bits unrecoverable - this changed as density got higher)

    With SSDs, your operating system has very little control over what bits a write is touching, a lot more was moved into the firmware on the flash memory itself

    So SSDs need a special command “Secure Erase” to wipe them
