It's been a good 15 years (joined 2007).

Twitter helped me travel the world, meet so many awesome people, make amazing friends (including my long term love).

See you all on the other side.

One of the suggestions I received yesterday was to implement some classic crypto attacks on stream.

To start let's go through cryptopals challenges which cover some really nice ones.

Come hang out/ask questions/play along!

Today on stream: Now that we can run Doom on our little risc-v OS we should probably start to make it playable (start setting up interrupt controllers / keyboard &mouse drivers / a clock etc.).

Today on stream, with the VGA driver and ELF loader written, we are finally going to get Doom running on our little risc-v operating system - after we write a few environment calls for libc hooks...

Come hang out / ask questions / play along.

Plan for the stream today is to implement seed pruning into our little Super Mario Bros. Fuzzer to prevent our backlog from filling up with low quality inputs.

Today on stream we formalized PCI enumeration, and got a quick little QEMU VGA driver up and running. (Now on youtube: youtube.com/watch?v=MKL0xU…)

Next OSDev stream we will see if we can get Doom running on our little OS!

Today on stream I'm going to be working on the seed selection algorithm in my little NES/Super Mario Bros. fuzzer.

Let's finish off setting up page tables and jump into playing around with PCI.

I'll be streaming some Super Mario Bros. (NES) fuzzer development today (Twitch: twitch.tv/pseudosarah)

Come hang out / chat / ask questions / learn about fuzzing.
