This looks interesting… A tool for viewing differences of object files.

Can anyone tell me what I'm doing wrong? I placed my data into virtual memory like the book said, but then I accidentally flushed the TLB and now I can't find it anymore. Everyone tells me to "walk the page directory, but I've tried that already. *you see a dragon dragging a folder containing blank pages along using a leash*

I was curious whether to prefer multiple inb instructions for code clarity, or to use inw/inl to make the code faster.

Results: All the instructions are approximately equally fast per _instruction_ (not per byte!). Prefer longer reads if you want to have fast I/O bus accesses.

I want to write a #ProgrammingLanguage… like a mixture of #C and #Rust like syntax. I call it Osmium, like the periodic table element. I’m developing on #Linux. This will be a #Hobby of mine, not anything serious, maybe never published to the net in the end. It could be aimed at enhancing #OSDev somehow???

Anyone got any ideas and resources they could share with me?
