Migrating from Go to Rust

Go developers considering Rust are often motivated by correctness guarantees, runtime tradeoffs, and developer ergonomics, rather than performance. Rust's type system and borrow checker provide stronger guarantees and more explicit control over runtime behavior, but can be more verbose and require a different mindset.

C constructs that still don't work in C++

https://lospino.so/images/lospino-trail.png
C++ is not a superset of C, with differences in object model, initialization model, and invariants, requiring explicit language mode labeling. C++20 and C23 changes, such as designated initializers and function declarator rules, affect compatibility and require careful consideration of language mode.

I love my Bluetooth keyboard

https://liquidbrain.net/images/b000a555.jpeg
I recently went on a ten day trip to China where I didn’t take my computer.1 I still wanted the ability to take notes quickly, so I bought a Bluetooth keyboard to use with my phone. I hear all my Mac friends laughing at me. We’ve had that for years, Kai. Still, it’s nice. I love being able to type quickly and use copy/paste. And it’s nice not to have to lug my computer around either — or buy ...

The Eternal Sloptember

The user believes AI agents will lead to a costly mistake in software development as they cannot truly program and will produce more low-quality code than ever before. They think large organizations will be hurt the most by AI adoption due to slower feedback loops and less alignment, leading to a dark age for quality software.
