While using a full-blown filesystem for storing your data in non-volatile memory is common practice, those filesystems are often too big, not to mention annoying to use, for the things I want to do. My solution?

I've been hard at work creating the sequential-storage crate. In this blog post I'd like to go over what it is, why I created it and what it does.

At Tweede golf we're big fans of creating applications on embedded devices with Rust and we've written a lot about it.

But if you're a hardware vendor (be it chips or full devices/systems), should you give your users Rust support in addition to your C support?

In this blog I argue that the answer to the question is yes.

At Tweede golf we are convinced that if software is written in Rust, it will be more robust (compared to legacy languages such as C, C++ or Java), and more efficient (compared to code written in PHP or Python and again, Java).

In order to get more robust software out there, we have to get Rust code running on computers of people who are not themselves Rust developers.

We're happy to announce that the Internet Security Research Group has officially made us the maintainers of the open-source memory-safe implementation of NTP, ntpd-rs. As such, we are now also looking for early adopters.

The implementation includes a server and client, as well as full support for Network Time Security (NTS), which brings encryption and greater integrity to time synchronization. Timing is precise and stable, as reflected by excellent performance in the NTP pool.

While working on the Roc compiler, we regularly dive deep on computer science topics. A recurring theme is speed, both the runtime performance of the code that we generate, as well as the performance of our compiler itself.

One extremely useful technique that we have been playing with is data-oriented design: the idea that the actual data you have should guide how code is structured.

TrustZone-m is a technology by ARM that allows you to create a Trusted Execution Environment (TEE) in your software. You can use it for example to keep your encryption keys secret or to separate a big vulnerable networking stack from your own code.

Over the last three months I've been working on a set of crates (Rust libraries) with the aim of making the usage of TrustZone-m a lot easier.

Our year in Rust

A company-changing year in a short story,
begins with a thank you, for this new-found glory.

We want to be clear in this prelude,
It is to Rust we owe our gratitude.
