Hello everybody. I am finishing my PhD soon, an industrial PhD on software migration. A quick brief: I have 10 years of experience in Pharo and another 10 years in other technologies. I want to learn if there are any opening positions for working in Pharo/Smalltalk. Please feel free to talk to me privately. I attached my CV. Cordially, Santiago.

New Memory Profiler
by Sebastian Jordan Montano Feb. 24, 2023

Feb. 24, 2023

Hello, I have been working on a new Memory Profiling for profiling object allocations. The profiler has reached a first stable version and I would like to share it with you. [ https://github.com/jordanmontt/illimani-memory-profiler | https://github.com/jordanmontt/illimani-memory-profiler ] The profiler gives some statistics, cool visualizations, like a heat-map, about the allocations and memory usage. If you want to profile the memory of some applications, this tool can help you. Also, if you have some use cases or you have some feedback please let us know because we are looking to improve the tool :) Cheers, Sebastian Jordan

by bajger＠gmail.com Feb. 24, 2023

Feb. 24, 2023

Hi there! \ Iâm looking for someone, who could do review of PR that implements new test runner for Exercism project that includes Pharo track. It is nice integration of using Pharo from command line, Docker (with different build args for loading correct baseline) and testing the test suite with json output (according to Exercism specific format). \ Exercism core maintainters lack knowledge of Pharo. Your help is welcome! PR here: https://github.com/exercism/pharo-smalltalk/pull/563 Related Docker part (already reviewed): https://github.com/exercism/pharo-smalltalk-test-runner/pull/16 Cheers, David

You will have 30 min for presentations and 45 min for hands-on tutorials. The list of topics for the normal talks and tutorials includes, but is not limited to the following: - XP practices, Development tools, Experience reports - Model driven development, Web development, Team management - Meta-Modeling, Security, New libraries & frameworks - Educational material, Embedded systems and robotics - SOA and Web services, Interaction with other programming languages - Teaching Pearls and Show us Your Business New this year!!! We added two types of sessions in addition to the regular talks and show us your projects sessions. Show your business 10 min session (Get prepared!!) Teaching pearls : we want some session on how to teach some design aspects. We want your tip and tricks to teach Smalltalk or OOP. We expect to have several 10 to 15 min sessions aggregated. ### How to submit? Make a Pull Request here https://github.com/ESUG/esug.github.io/tree/source/2023-Conference/talks [Or but only if you are not connected to the worldâ¦ send an email to stephane.ducasse(a)inria.fr] Title: [ESUG 2023] Please follow the template below the email will be automatically processed!

UK Smalltalk User Group Meeting - 22 February 2023
by Giovanni Corriga Feb. 14, 2023

Feb. 14, 2023

WebAssembly (WASM - https://wikiwand.com/en/Webassembly ) is an instruction format for portable high-performance code, run by a stack-based virtual machine. To Smalltalkers, this sounds very familiar. WASM is supported by the three most popular web browsers, and by other host platforms as well. Perhaps we can translate certain Smalltalk compiled methods to WASM, augmenting our support for physical processors and for livecoding the Web. For our February meeting, Craig Latta will describe his initial experiments, using the Epigram compilation framework ( https://thiscontext.com/epigram ). Craig Latta ( https://thiscontext.com/ ) is a research computer scientist in Berkeley and Amsterdam, with interests including livecoding, music performance, and interactive visualization. The discovery of a mysteriously-placed copy of the Blue Book at university led to stints at several exploratory labs, and a pursuit of improvisation wherever code is found. 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/291365015/ ) to receive the meeting details.
