Reverse Engineering the Facebook Messenger API
Note: The focus of this article is to explain the process of reverse engineering, and it is not continually updated to reflect ongoing changes in Facebook APIs. If you are looking for updated details, consider basing your work on open-source projects like mautrix/meta , which is developed by my employer Beeper .

C++ Coroutines
C++ is late to the coroutine party, compared to other programming languages, but they are part of C++20. Prior to coroutines, a C++ programmer had two choices, roughly speaking:

Zig: Upcoming release postponed two more weeks and lacks async functions
I’ve been saying the upcoming 0.11.0 release of Zig would have async/await/suspend/resume for 9 months now. You can probably find 10 different places where I promised in writing or in front of a camera that this next release would have this feature.

Using Zig to Unit Test a C Application
Zig is a new, independently developed low-level programming language. It’s a modern reimagining of C that attempts to retain C’s performance while embracing improvements from the last 30 years of tooling and language design. Zig makes calling into C code easier than any other language I’ve used. Zig also treats unit…

Goroutines: The concurrency model we wanted all along
Goroutines are the single feature that distinguishes Go from other languages. They look very much like threads, but they are cheap to create and manage. Go's runtime schedules goroutines onto real threads efficiently so you can easily create lots of goroutines.

The Maddest My Code Made Anyone
I was lucky enough to grow up through the early 2000’s, during the golden age of Half-Life mods. Industry classics like Counter-Strike (CS) had just been invented, every month brought new mods to try, and files were too big to download on a dial-up connection so you’d leech them off a server at a big local LAN party…

Why split lexing and parsing into two separate phases?
“lex and yacc” are two terms that are used together so often that they can seem indivisible. lex takes a string as input and divides it up into lexemes (roughly speaking “words”) and yacc takes a sequence of lexemes and parses them. Since some parsing approaches such as recursive descent parsing unify these phases…

The joys of maintenance programming (2011)
In the old days when I started programming, green programmers trying to build their skills and get experience started out doing maintenance programming. Only the old hands got to write new code. The newbies cut their teeth debugging and fixing musty old code that still worked for the business. I’ve done my share of…

Curl audit: How a joke led to significant findings
In fall 2022, Trail of Bits audited cURL, a widely-used command-line utility that transfers data between a server and supports various protocols. The project coincided with a Trail of Bits maker week, which meant that we had more manpower than we usually do, allowing us to take a nonstandard approach to the […]

Emitting Safer Rust with C2Rust
In this post, we will discuss recent results from Immunant and Galois in extending C2Rust to emit memory-safe Rust in certain cases. With this work we aim to shift a meaningful part of the translation burden from the human to the machine. Up until now, C2Rust has only been able to translate C to unsafe Rust that is no…

UPDATE: Wow, this post has gotten popular! I’ve written a new post that adds new papercuts combined with concrete suggestions for how C++ could improve, if you are interested. Also, if you want to read more about C++’s deeper-than-papercut issues, I recommend specifically my post on its move semantics. Thank you for…
