WebAssembly: Docker without containers

Published: 21 December 2022
Tags: docker, php, web assembly

Asen Alexandrov gives an overview of Web Assembly (wasm) and offers a hands-on example on building a wasm container, comparing it to native binaries, and then comparing it to traditional containers.
Some highlights:

  • Wasm is a new standard that allows for portable binaries that can run on a variety of environments
  • Wasm has its origins in the web and is supported by all major browsers
  • Wasm can handle interpreted languages (in addition to compiled languages) by compiling the interpreters to wasm

Docker volumes on MacOS are slow and how to fix it

Published: 4 December 2022
Tags: containers, docker, macos

I've been hearing about performance issues when running Docker on the new M(1/2) macs, so thought I'd feature this deep-dive on the topic. Paolo Mainardi covers the fundamentals of how docker works on macs, then goes into how to fix performance issues. There are also a bunch of links to other good resources for specific topics.
Some highlights:

  • Docker is a tool used to run containers, which are self-contained systems, on different environments
  • Docker containers are still Linux processes and need a Virtual Machine (VM) to run on other operating systems
  • Having to use a VM complicates things regarding storage for docker containers

Data-driven performance optimization with Rust and Miri

Published: 8 December 2022
Tags: rust, unix, compiler, linux

Keaton Brandt walks us through optimizing Rust code for one of the Advent of Code challenges.
Some highlights:

  • Profilers are tools that analyze how well a piece of software is performing
  • Perf-based libraries like flamegraph work by sampling the stack trace of your software on a regular interval
  • Miri is a project owned by the rust team with the aim of running rust code in an interpreter, primarily to help with debugging

* Amazing
* Articles not relevant to me
* Articles were relevant, but badly written
* Summaries told me everything I wanted to know
* I like turtles
