Welcome to nickb.dev, a blog by Nick Babcock! Below are my most recent articles. You can find the history of all my writings in the archive or just find out more about me.
Wasm compression benchmarks and the cost of missing compression APIs
Published on: What is the best way to compress data in the browser? Is Wasm faster than JS? I have put together a small site that will let you run benchmarks within the browser.
Rethinking web workers and edge compute with Wasm
Published on: It dawned on me that I could be treating web workers almost as if I am communicating with a server, and that the same tools for managing application logic for remote communications, can be used for local message passing with web workers. I can also deploy the same client side Wasm on the edge for low latency validation and data extraction.
Cloudflare Tunnel saved my home server when my apartment got a new ISP
Published on: My apartment building recently switched ISPs. After they finished installing, all the sites I host on my home server were no longer accessible. Cue the panic. My server relied on a publicly addressable IPv4 address, so how I can fix this?
Avoiding allocations in Rust to shrink Wasm modules
Published on: “Rust lacks a runtime, enabling small .wasm sizes because there is no extra bloat included like a garbage collector. You only pay (in code size) for the functions you actually use.” Easier said than done, as one has to watch out for allocations as they may significantly impact the Wasm module side.
Favoring SQL over Redis for an evergreen leaderboard
Published on: Redis is a natural choice for a database when showcasing a leaderboard, but sometimes introducing a database for this purpose can be excessive and unnecessarily complicate an application. Don’t overlook that SQL database you’re already employing.
DEFLATE yourself for faster Rust ZIPs
Published on:The Rust crate for handling ZIP files, zip-rs is quite flexible. The zip crate is compiled with builtin features to support deflated data (among other compression algorithms). This makes it incredibly easy to hit the ground running for reading and writing zips.
We can disable these builtin features. This may sound undesirable, but in fact, it is my new favorite way to integrate zip functionality into apps I write.d
Avoiding dynamic CSS-in-JS styles in React
Published on: The React working group have given a lukewarm signal to dynamic CSS-in-JS libraries. They advocate for static CSS extraction with dynamic styling relegated to inline styles. I convert a component from CSS-in-JS to CSS modules and inline styles, and give a positive outlook for adding Tailwind to the mix.
The footgun with Docker Compose shared configurations
Published on: Docker Compose has a nice feature where several Compose files can be seamlessly fashioned together and allow for configuration reuse across environments. There is, however, counterintuitive behavior that can lead one to accidentally overwrite remote container images. Since I lost several hours to this, I figured I’d write about it to sear the behavior into my memory.
