Where the top of the stack is on x86 (2011)
I've noticed more than once that some programmers are confused about the direction in which the stack grows on x86, and what "top of the stack" and "bottom of the stack" mean. It appears that this confusion is caused by a basic mismatch in the way people are used to thinking about stacks, and in the way the stack on…

Java's records, Lombok's data, and Kotlin's data classes
While all three remove boilerplate, the similarities don't go much further. Records have stronger semantics with important downstream benefits, which makes them better*. (* not always; depends on circumstances; excuse the clickbait)

I Hacked Google App Engine: Anatomy of a Java Bytecode Exploit
Back in college, I was very interested in Java bytecode. When I got an internship at Google in 2013, I was skeptical of the security of the Java version of Google App Engine and got permission to spend the last week of my internship doing a mini red team exercise, trying to break into App Engine. This is the story of…

Branchless Coding in Go
So, I was recently inspired by a coworker’s design to pack what would have been JSON (JavaScript Object Notation) data into a bunch of bit fields in an array of 64-bit elements. Binary arithmetic, bit-packing, and high performance are fun for me, so I thought of some ways to improve it, for learning purposes. Then I…

Chiptunes on an ATtiny4 and the 3 Cent Micro
Ever since hearing about Rob Miles' Bitshift Variations in C Minor , a 4-voice polyphonic 16 minute piece of algorithmically generated music, I wanted to implement it in hardware. Getting it onto just any microcontroller seemed too easy , so I wanted it to run on the smallest µC I could find — the ATtiny4. A while…

Building video chat into my personal website using WebRTC, WebSockets, and Go
Recently I've become more and more interested in how WebRTC works, so a few weeks ago I decided to add a page to my website where I could set up peer-to-peer video chats. There are plenty of libraries and services out there to make this extremely easy, but knowing that WebRTC is now well supported natively across…
