by Guillermo Polito Jan. 9, 2023

Jan. 9, 2023

Hi all, Iâve drafted a phep proposal for the new finalization mechanism, so we can discuss it here! https://github.com/pharo-project/pheps/pull/14 <https://github.com/pharo-project/pheps/pull/14> A proposal describing a new finalization mechanism for Pharo with the following properties: â¢ API independent from its implementation â¢ Avoids memory leaks This document describes both a finalization API as a Pharo library and an efficient virtual machine implementation through Ephemerons.

What did happen with CustomHelp?
by Denis Kudriashov Jan. 3, 2023

Jan. 3, 2023

Hi. There is no CustomHelp in Pharo 11 anymore. And no Help Browser in the menu. What is the story behind it? Is there any new alternative? Now any external {Project}-Help package is not loadable into the new system. Regards, Denis

Pharo VM Release - v9.0.21
by tesonep＠gmail.com Dec. 14, 2022

Dec. 14, 2022

Hello, I have released a new version of the Pharo VM for Pharo 9, Pharo 10 and Pharo 11. This VM is accessible right now from Zero-Conf, updating it in the Pharo Launcher or using the usual downloads (as described in pharo.org/download) This version includes a series of bug fixes and upgrades on the third-party libraries. Changelog: - Implementing High resolution clock for ARM64 (Used during profiling) - Updating third party libraries for all the graphic layer. - Fixing a performance regression on the allocation of opcodes and fix-ups. Cleaning only the ones that are going to be used. Like this, this version has the same speed than before when allocating in the stack. - Correctly handling the encoding of the command line arguments of the VM (Windows) - Allocating the opcodes and fixup structs only once and reusing them (Reducing risk of C Stack Overflow) Thanks a lot, and any doubt please let me know. Cheers, Pablo on behalf of the whole Pharo team. -- Pablo Tesone. tesonep(a)gmail.com

[Issue Tracker] Please check your issues
by Marcus Denker Dec. 14, 2022

Dec. 14, 2022

Hi, The issue tracker has a bit the problem that outdated issues are never cleaned - sometimes PRs are merged but the issue is not closed because it was never connected to the PR ( github sometimes just does not do it correctly ) - Duplicated reports, bug is fixed but the other issue was closed - Problem fixed due to other reasons Or your issue might have seen someone asking a question. People tend to just wait for an answer to those. Or maybe the issue has just not enough information for others to take action? Maybe you could submit a PR instead of just describing the change you think should be done? The best would be if everyone who opened an issue would check all the issues they submitted. you can just add a filter to https://github.com/pharo-project/pharo/issues, e.g. author:MarcusDenker shows you all that I submitted Marcus

Looking for a job....
by stephane ducasse Dec. 13, 2022

Dec. 13, 2022

Hello, My name is Daniel Camacho, for the last 6 months I've been working as a Software Engineering intern in the research team RMoD at Inria. We are focused on object-oriented programming languages designing and modeling. In this context, I've implemented a meta-object protocol that allows developers to instrument objects at runtime. This will be the base layer from which a new generation of debugging tools focusing on objects rather than focusing on the execution stack will be built. Now ending my internship, I am seeking for a software engineer position, I am particularly interested research implementation projects, web development and cloud computing field. The fact that I successfully completed my internship assignment is a proven track record of my learning and problem solving abilities. I remain at your disposal to schedule an interview so that we can discuss on how I may be a good fit to your company. Thank you in advance for your attention and I wish you an excellent day. Sincerely Daniel Camacho Santa Cruz Software engineer T: +33 695489293
