I’m so excited (and terrified) to confirm I’ll be speaking at Gleam Gathering to discuss a potential future with Gleam and WebAssembly!
gleam.run Gleam Programming Language @gleam.run · 4d
All the speakers confirmed for Gleam Gathering!

The lineup includes Gleam and Lustre Core Teams members:

Somewhat surprising (to me) advice in Google's C++ style guide:

"Try to avoid unsigned types (except for representing bitfields or modular arithmetic). Do not use an unsigned type merely to assert that a variable is non-negative."

Example of a possible bug: abseil.io/tips/227

(via @wingolog.org)
On Unsigned Integers Unsigned integers are good for representing bitfields and modular arithmetic. Because of historical accident, the C++ standard also uses unsigned integers to represent the size of containers - many members of the standards body believe this to be a mistake, but it is effectively impossible to fix at this point. The fact that unsigned arithmetic doesn't model the behavior of a simple integer, but is instead defined by the standard to model modular arithmetic (wrapping around on overflow/underflow), means that a significant class of bugs cannot be diagnosed by the compiler. In other cases, the defined behavior impedes optimization. That said, mixing signedness of integer types is responsible for an equally large class of problems. The best advice we can provide: try to use iterators and containers rather than pointers and sizes, try not to mix signedness, and try to avoid unsigned types (except for representing bitfields or modular arithmetic). Do not use an unsigned type merely to assert that a variable is non-negative.

My colleague Antonio Maiorano added some basic support for capturing Chrome #WebGPU content with RenderDoc recently! I wrote a brief article about how to use it. It's pretty primitive right now, but I have high hopes that we can improve the ergonomics in the future.

A few weekends ago I wrote a logic analyzer in Spade 🐠, and it took less than 4 hours

I figured I'd write a blog post to show how that was possible and how the code works: blog.spade-lang.org/quickscope/
A creenshot with a header, some code, and text at the bottom The header is green text saying "Quickscope" with the "o" replaced by a COD Modern Warfare 2 intervention player model. The source code is syntax highlighted Spade code that describes an integrated logic analyzer The text at the bottom has the same style as the header and says "A logic analyzer in 4 hours"

A major improvement for dynamic linking landed: the main module is built statically, without relocation overhead, making it smaller and faster. Only dynamic libraries now have relocation overhead. This makes dynamic linking much more useful 🚀
