The Druid Metacompiler Guille Polito Matias Demare Virtual Machines (VMs) combine interpreters and just-in-time (JIT) compiled code to achieve good performance. However, implementing different execution engines increases the cost of developing and maintaining such solutions. JIT compilers based on meta-compilation cope with these issues by automatically generating optimizing JIT compilers. This leaves open the question of how meta-compilation applies to baseline JIT compilers, which improve warmup times by trading off optimizations. In this talk we present Druid, an ahead-of-time automatic approach to generate baseline JIT compiler frontends from interpreters. Language developers guide meta-compilation by annotating interpreter code and using Druid’s intrinsics. Druid targets the meta-compilation to an existing JIT compiler infrastructure to achieve good warm-up performance. We applied Druid in the context of the Pharo programming language and evaluated it by comparing an autogenerated JIT compiler frontend against the one in production for more than 10 years. Our generated JIT compiler frontend is 2x faster on average than the interpreter and achieves on average 0.7x the performance of the handwritten JIT compiler. Our experiment only required changes in 60 call sites in the interpreter, showing that our solution makes language VMs easier to maintain and evolve in the long run. Smalltalks 2025

Sound Over Boilerplate - Accessible Plug-Ins Development With Phausto and Cmajor - Domenico Cipriani https://audio.dev/ -- @audiodevcon​ Sound Over Boilerplate - Accessible Plug-Ins Development With Phausto and Cmajor - Domenico Cipriani - ADCx Gather 2025 Complex programming languages, build tools, and code signing processes create barriers that prevent musicians and sound artists from developing audio plugins. Phausto addresses this challenge as a free, open-source DSL built on Pharo Smalltalk's accessible syntax and integrated IDE. It integrates the Faust compiler for direct access to professional-grade oscillators, filters, and effects, while seamlessly exporting to Cmajor patches for rapid plugin deployment. This session introduces Phausto fundamentals and demonstrates workflows for shipping Cmajor-based plugins using free tools. We'll explore distribution models that enable sound artists to independently share and monetize their creations. --- Domenico Cipriani Domenico Cipriani (aka Lucretio) is a minimalist dance music producer and sound researcher with over 100 vinyl releases and performances at iconic clubs including Berghain, Tresor, Rex, and Fabric. He is co-founder of the influential label Restoration, a key player in the vinyl resurgence of the late 2000s. Holding an M.A. in Linguistics from the University of Padova, Domenico bridges research and music technology. Since discovering Symbolic Sound Kyma in 2016, he has specialized in Open Sound Control protocols. He currently conducts computer music research with the Inria EVREF team in Lille and develops audio plugins with the indie company Soft Computing, all while remaining active as a DJ and live performer. Domenico is also the creator of Coypu and Phausto. With Coypu, he has performed at the International Live Coding Conference in Shanghai (2024) and Barcelona (2025). --- ADC is an annual event celebrating all audio development technologies, from music applications and game audio to audio processing and embedded systems. ADC’s mission is to help attendees acquire and develop new audio development skills, and build a network that will support their audio developer career.
