The Rust core team recently released a call for blog posts as part of the 2021 roadmap for Rust. In this post I will detail my own experience with Rust, and areas I’d like to see improved during 2021.

I recently had an ongoing issue with the deleted CacheDelete daemon using huge amounts of CPU time almost constantly. This post covers how I fixed it and a few tips for OS X recovery and performance improvements.

This post covers why I believe local and national governments should adopt and invest in Free and Open Source Software (FOSS).

This has been in the news recently due to the city of Munich renewing it’s LiMux Linux distribution thanks to an agreement between the local SDP and Green politicians, and the efforts of the Public Money, Public Code campaign.

ALMA (available as alma-git on the AUR) is a tool for creating persistent LiveUSB installations of Arch Linux. With one command you can generate a customised installation on a USB stick (or any other removable media) including the packages and config files you want, with full persistence.

This is very useful for disk recovery and system maintenance, and a great tool for all Linux users. Especially with the customisation options provided by collections of preset files (such as arch-i3-usb).

This post is a retrospective of my first “useful” Rust project. vopono is a Linux program to launch applications in temporary network namespaces (managed by vopono), in order to run specific applications through VPN connections, without affecting the rest of your system.

vopono is available on Github (and in the AUR on Arch Linux) and licensed under the GPLv3 license (see reasoning here).

We’ll consider the motivation and background to creating vopono, the upsides and downsides of writing it in Rust (and existing issues), and some points about starting new side projects in general. I hope this helps new Rust programmers starting their own first projects, or for other programmers to consider using Rust.

In this post we will set up a simple, serverless data ingestion pipeline using Rust, AWS Lambda and AWS SES with Workmail.

We will handle multiple types of AWS events with one Lambda function, parse received emails with the mailparse crate, and send email with SES and the lettre crate.

The complete code for this example is available on GitHub here.

In the post we will investigate the main concepts of Data-oriented Design using Rust.

The source code for this example is available on Github.

In this post we will explore a brief example of asynchronous programming in Rust with the Tokio runtime, demonstrating different execution scenarios. This post is aimed at beginners to asynchronous programming.

The source code for this example is available on Github. A branch using the async-std runtime is also available (contributed by @BartMassey).

In this post we will set up a very simple data ingestion process with Rust and AWS Lambda.

The complete code for this example is available on GitHub here.
