DATE CORRECTION - UKSTUG Meeting - Javier Pimas -- Live Metacircular Runtimes: The case of Egg Smalltalk - 29 May 2024

by UK Smalltalk

Egg is a new Smalltalk dialect that was designed from scratch to incorporate some interesting features: A module system with namespaces that replaces the old-good Smalltalk global. Dynamic identifiers, which are bound lazily similarly to how methods are lazily bound. A multi-VM architecture, with different VM implementations written in C++, Pharo, JavaScript and Egg. The Egg-in-Egg VM is special in that the VM component is just another module of the system, creating what we have named Live Metacircular Runtimes (LMRs) [1]. The most interesting characteristic of LMRs in Smalltalk is that they can be developed using standard Smalltalk tools, which shorten feedback loops when doing VM development. During the talk I'll show a little bit about Egg and its LMR, and how not only VM developers get more productive when writing VMs, but also application developers can better understand what the VM does behind the scenes. [1] https://arxiv.org/abs/2312.16973 - Live Objects All The Way Down: Removing the Barriers between Applications and Virtual Machines Javier Pimas is a fan of high-level low-level programming. He has been successfully mixing Smalltalk and assembly code for more than a decade. Within Bee Smalltalk, SqueakNOS and now Egg Smalltalk projects he has been trying to make live-programming of system-level concerns more practical to application programmers. Javier works for Labware and Quorum Software, where he applies his expertise to real-world challenges while pursuing a PhD in Computer Science at Buenos Aires University. This will be an online meeting from home. If you'd like to join us, please sign up in advance on the meeting's Meetup page ( https://www.meetup.com/ukstug/events/300511322/ ) to receive the meeting details. Don’t forget to bring your laptop and drinks!

Re: Open Call: Object-Centric Breakpoints experiment

by Steven Costiou

Dear community, we are still looking for participants for our experiment in the EVREF team! Please help us! We need 15 more participants, if you are interested and if you believe you can work your way around a debugger, the experiment is fully available online here (using Pharo 9): https://github.com/Pharo-XP-Tools/XPImageGeneration/tree/exp-ocd We would like to show our results at ESUG, but for that we really need these 15 additional participations so that we can trust the results better. Thanks in advance, and many thanks to the people who already participated! Steven.

CfP: The Art, Science, and Engineering of Programming Journal volume 9

by Jonathan Edwards

The Art, Science, and Engineering of Programming accepts papers that advance knowledge of programming. Almost anything about programming is in scope, but there should be a clear relevance to the act and experience of programming. Papers must be written in a scholarly form, contextualizing their ideas with prior research and practice. We accept descriptions of work under different perspectives: Art: knowledge and technical skills acquired through practice and personal experiences. Examples include libraries, frameworks, languages, APIs, programming models and styles, programming pearls, and essays about programming. Science (Theoretical): knowledge and technical skills acquired through mathematical formalisms. Examples include formal programming models and proofs. Science (Empirical): knowledge and technical skills acquired through experiments and systematic observations. Examples include user studies and programming-related data mining. Engineering: knowledge and technical skills acquired through designing and building large systems and through calculated application of principles in building those systems. Examples include measurements of artifacts’ properties, development processes and tools, and quality assurance methods. The remaining submission deadlines for Volume 9 are June 1 and October 1. For further details see the official CfP <https://programming-journal.org/cfp/>.
