Automated Assurance through Differential Fuzzing
This blog describes the concept and benefits of differential fuzz testing. In addition, the post describes setting up, executing and analyzing the results of a differential fuzzing campaign for the Libkeccak and XKCP cryptographic libraries.by Fabien Chouteau
Ada/SPARK Crate Of The Year 2022 Winners Announced!
In June of 2022 we launched the second edition of the Ada/SPARK Crate Of The Year Awards. We believe the Alire source package manager is a game changer for Ada/SPARK, so we want to use this competition to reward the people contributing to the ecosystem. Today we are pleased to announce the results. But first, we want to congratulate all the participants, and the Alire community at large, for reaching 320 crates in the ecosystem in January of this year. We truly believe in a bright future for the Ada/SPARK open-source ecosystem with Alire at the forefront. Reaching this milestone is a great sign,both inside and outside the Ada/SPARK community, of the evolution and the energy of the ecosystem.

Coroutines in Ada, a Clean but Heavy Implementation
A few months ago I was reading this article about coroutines in game development and how they are great tools for writing scripts (as in movie scripts) in the same language as the game engine. Until then I heard about coroutines but never really gave them a thought, this piqued my curiosity.by Fabien Chouteau
Embedded Ada/SPARK, There's a Shortcut
For years in this blog my colleagues and I have published examples, demos, and how-to’s on Ada/SPARK embedded (as in bare-metal) development. Most of the time, if not always, we focused on one way of doing things: to start from scratch and write everything in Ada/SPARK, from the low level drivers to the application. While this way of doing Ada/SPARK embedded will yield the best results in terms of software quality, it might not be the most efficient in all cases. In this blog post I want to present an alternative method to introduce Ada/SPARK into your embedded development projects.by Fabien Chouteau

A New Era For Ada/SPARK Open Source Community
Today we have two exciting announcements for the future of the Ada/SPARK ecosystem.by Paul Jarrett
Ada Crate of the Year: Interactive code search
A retrospective on learning Ada and developing a tool with it in 2021 from 2021 Ada Crate of the Year Winner Paul Jarrett.by Fabien Chouteau , Joffrey Huguet
Quite Proved Image Format
A few weeks ago a piece of code went viral in the online dev community. The “Quite OK Image Format” (QOI) is a fast, lossless image compression designed to have a very simple implementation (about 300 lines of C). Shortly, a few alternative implementations popped up here and there, and in this kind of situation we are eager to show what Ada/SPARK can bring to the table.by Fabien Chouteau
Ada GameDev Part 2: Making 2D maps with Tiled
In this second post of the Ada GameDev series we will see how to create game maps and export them to a format that is compatible with the GESTE library.by Fabien Chouteau
Ada GameDev Part 1: GEneric Sprite and Tile Engine (GESTE)
In this first entry of the series, I want to present my GEneric Sprite and Tile Engine (GESTE) project. The goal of GESTE is to bring the rendering and anesthetic of 8bit era game consoles to modern microcontrollers.by Fabien Chouteau
AdaCore at FOSDEM 2022
Like previous years, AdaCore will participate in FOSDEM. Once again the event will be online only, but this won’t prevent us from celebrating Open Source software and it is an opportunity for even more people to participate around the world.

An Embedded USB Device stack in Ada
A couple years ago I started to tackle what was probably my most daunting project at the time, an embedded USB Device stack written 100% in Ada.by Fabien Chouteau
Starting micro-controller Ada drivers in the Alire ecosystem
A few days ago, someone asked on the Ada Drivers Library repository how to add support for the SAMD21 micro-controller. Nowadays, I would rather recommend people to contribute this kind of micro-controller support project to the Alire ecosystem. I started to write a few instructions on how to get started, but it quickly became a blog-worthy piece of text.by Fabien Chouteau

SPARKNaCl with GNAT and SPARK Community 2021: Port, Proof and Performance
This post continues our adventures with SPARKNaCl - our verified SPARK version of the TweetNaCl cryptographic library. This time, we'll be looking at yet more performance improvement via proof-driven "operator narrowing", porting the library to GNAT Community 2021, and the effect that has on proof and performance of the code.by Fabien Chouteau
From Rust to SPARK: Formally Proven Bip-Buffers
I am following the evolution of the embedded Rust community and in particular the work of James Munns from Ferrous-Systems. One of the projects that caught my attention is bbqueue, a single producer, single consumer, lockless, thread safe queue, based on BipBuffers.by Fabien Chouteau
Mini SAM M4 Ada BSP
Beyond the great look, the Mini SAM M4 provide a powerful 120 Mhz Microchip SAMD51 Cortex-M microcontroller, a couple of LEDs and a user button. Let's program it with Ada.by Fabien Chouteau
Ada on any ARM Cortex-M device, in just a couple minutes
In this blog post I want to present a new tool that allows one to very quickly and easily start Ada programming on any ARM Cortex-M or RISC-V microcontroller.by Fabien Chouteau
First beta release of Alire, the package manager for Ada/SPARK
A few years ago we realized that having a package manager for the Ada/SPARK community would be a game changer. Since then, AdaCore has been sponsoring and contributing to the Alire project created by Alejandro Mosteo from the Centro Universitario de la Defensa de Zaragoza. With this blog post I want to introduce Alire and explain why this project is important for the `Ada`/`SPARK` community.by Fabien Chouteau
AdaCore at FOSDEM 2020
Like last year and the year before, AdaCore will participate to the celebration of Open Source software at FOSDEM. It is always a key event for the Ada/SPARK community and we are looking forward to meet Ada enthusiasts. You can check the program of the Ada/SPARK devroom here.
