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…

Branch predictor: How many “if”s are too many?

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…

Dave Herman’s contributions to Rust
I think the Rust language is a big success. When I think back on it I am in awe: so much had to go right to get where we are, and there were so many opportunities to go wrong. It took many tiny miracles for the Rust language to become what it has. Those miracles didn’t happen by accident though: each one was created…

What's Salesforce? (2019)
Customer relationship management (CRM) is the biggest, fastest growing software market in the world. $40B is spent on CRMs annually, and almost all companies have one. But for those of us that don’t directly use a CRM… what’s the big deal? A CRM is the source-of-truth for all customer data and interactions. Need to…

Python vs Common Lisp, workflow and ecosystem (2019)
I learned Java and C at school, I learned Python by myself and it was a relief. After 8 years working and doing side projects in Python and JavaScript (mostly web dev, Django/Flask/AngularJS/Vuejs), I am not satisfied anymore by the overall experience so I’m making Common Lisp my language of choice.I am not here…

The compiler will optimize that away
A lot of programmers believe that compilers are magic black boxes in which you put your messy code in and get a nice optimized binary out. The hallway philosophers will often start a debate on which language features or compiler flags to use in order to capture the full power of the compiler’s magic. If you have ever…

Will Linux phones stay around this time?
While working through the old posts in order to adjust the front matter (and sometimes more), I thought: Will this last? Or will this go south soon, like it did around with previous projects again? A recent reddit post reinforced this line of thought, so I decided to write down my thoughts on the issue.

How many engineers does it take to make subscripting work?
The select part is actually fine. But for updates, especially for complex updates, it could be pretty verbose and far from being ergonomic. What would you say to this syntax instead?
