I’m finding that there is a full playground in the ModR/M encoding, and this post is specifically about a SIB obscurity, only because of the way I see NASM assembling some of my assembly. Then I found other cool things NASM puts up with Consider this code: Functionally, they both result in the same thing. […]


Follow-up on creating Vm0wd2Qy > 9000

In my previous post, I have 10,000 characters that you would eventually get as the first part of your string […]

Conversions can be made between them: Not too interesting. This post is more about a string like “Vm0wd2Qy”: [2nd command is just there […]
