Author of books and tools for reverse engineering. Studebaker driver, but an awful mechanic. Home chip decapsulation. Currently writing a new assembler, to be released in February.
Our chip viewer just got an upgrade: now you can see microscope images, GDS, local interconnect and jump straight to project files. Spot something cool? Dive right into the design.

Is there a way to turn off retweets for some accounts in bsky?
My Following feed is entirely filled by one or two accounts who retweet dozens of dumb articles about politics, but whose original writing I'd still like to see.
butβ¦ isnβt the point of drinking coffee to sit there and read a book while you do?
the decline of reading for fun is maybe the single most depressing thing about the technological era weβre living through

The book Building a Debugger, featuring a robot designing a complex debugging machine on a drafting board
The book placed in front of a tortie cat
Building a Debugger is now officially released!
It guides you through building a whole native x64 debugger from scratch, dispelling all the magic and teaching you a ton about operating systems as it goes.
Even if you don't care about building a debugger, you can read it to your cat.
Here is some info on how to dump that ROM electrically.

If your 6500/1 does need to be replaced, consider sending me the dead one for ROM photography, as I'd love to add those photos to my collection without destroying a working 1520.
Going to the USENIX Security Symposium? Don't forget to also register for WOOT, the papers we selected are amazing π€©

It's nothing crazy but I finally documented and released the tooling I created for inspecting the instruction behavior while building the lifter for my Binary Ninja plugin https://github.com/jrozner/msp430-testbench . Maybe this approach will be helpful for other embedded architectures for others?

For Xennials like me that witnessed the boundless optimism of the 1990's, and watched the disaster of the Chicago Boys "helping Russia reform", this is excellent reading:

A picture of an electronic gaming device with IBM ThinkPad styling, but ever so slightly reorganised Nintendo GameBoy layout. There are A and B buttons, Select and Start, a screen shade, and instead of a direction pad, a beautiful simple red TrackPoint.

Three small infrared remote controls, for turning off televisions.
I've been toying around with the open source TV-B-GONE design from Adafruit and Mitch Altman. Cutting the brightness and switching to SMD components results in a board that rides on a coin cell, easily forgotten in a coat pocket.
Maybe an LED Throwie variant is next?
My assembler's support for the SM83 architecture used in the GameBoy is coming along nicely. The left is a Hello World cartridge and the right is a disassembly of the boot ROM that shows the Nintendo logo at startup.
Source and binaries will be available in February.
