Lies we tell ourselves about email addresses

https://gitpush--force.com/commits/2026/06/lies-we-tell-ourselves-about-email/padme-right.jpg
Email addresses are complex and have many edge cases, including international characters, case sensitivity, and server-specific features that can lead to unexpected behavior. To handle email addresses safely, don't overthink it and use simple client regex for user input, verify addresses with a confirmation code or link, and use citext or COLLATE utf8mb4_general_ci for unique index checks.

Test-case reducers are underappreciated debugging tools

https://tratt.net/laurie/blog/extra/2026/test_case_reducers/shrinkray1.png
Test-case reducers are tools that can automatically reduce the size of an input to a program, making it easier to debug, and can be used in various ways, including to reduce nondeterminism and drive down the length of program traces. By writing custom interestingness tests, programmers can use test-case reducers to focus on specific properties of the input, such as reducing the length of ...

Grit: Rewriting Git in Rust with agents

Bit Propagation over a Noisy Grid

Below is an open problem, an approachable problem, one perhaps you will be the one to solve! We send a bit over a noisy grid, starting from the origin and propagating out as a wave. Can we recover the original bit when looking at just the wavefront? This is easy to solve for 1D, mostly solved in 2D, and still open in 3D and above. Here is the lecture that introduced the problem to me, as well ...
