"An idiot admires complexity, a genius admires simplicity."

• Terry A. Davis

I wrote the PCILeech DMA Firmware Guide: a comprehensive PCIe endpoint modeling guide. It took months. It almost killed me.

I work at the silicon interface: PCIe, DMA, FPGA, firmware, the space where software ends and atoms begin. Some of it I can talk about. Most of it I can't. The stuff I can't talk about is the stuff that actually matters.

I don't sell firmware. I don't sell anything. I gave away the knowledge because knowledge doesn't expire. Firmware does. I have dignity.

Tech: C, x86 asm, Verilog, Rust. Linux kernel. Windows internals. PCIe at the TLP level. FPGA at the gate level.

I'm going to try to get back to the people who have been trying to contact me for over a year. I'm sorry. I don't know what's gonna happen. I'm going in tomorrow to find out if I need surgery. If I disappear again, that's why. If I don't come back, the guide is here. The knowledge is free. That's all I could do.

The birds never figured it out. Still birds.
