[ANN] Soil release v1
by Norbert Hartl June 30, 2024

June 30, 2024

...we said at last ESUG that there will be a release soonish but as usual it doesn't go that fast. But now we are very happy to announce that Soil has a first public release v1. So what is soil? Soil is an object oriented database in pharo <http://pharo.org/>. It is transaction based having ACID transactions. It has binary search capabilities with SkipList and BTree+ indexes. It aims to be a simple yet powerful database making it easy to develop with, easy to debug with, easy to inspect, ... More details at https://github.com/ApptiveGrid/Soil This release is still considered early stage because although in ApptiveGrid there are over 4000 instances of it and there are other users there isn't a wider range of use cases, yet. So it is not fully battle tested. This just as reminder when you start compaining I need somewhere to point my finger to and say "I told you!" ;) there are few things missing that you might expect like garbage collection, etc. So but it is definetely usable and awaiting the brave ones of you to try. Hopy you enjoy it! Norbert & Marcus

Info required for bootstrapping pharo on GNU Guix
by Nicolas Graves May 21, 2024

May 21, 2024

Hi Pharo community, I'm trying to package pharo in the GNU Guix linux distribution. Since the distribution is focused on reproducibility and avoids using binary code when possible, for that I need to reproduce the bootstrapping steps that are embedded in Pharo. I understand from some developper online comment that this is possible. I've started to work on this and it seems feasible, at least I get the dependency loop, what I've some difficulty is to get precisely when it's possible to get started. ------------------- | v pharo VM pharo â§ | ------------------- If I'm correct, - bootstrapping is very clear after version ~7.0.0, and with a proper build, just follow the distribution numbers in wget's with a cmake build-system. - for earlier versions, there's the repository https://github.com/pharo-project/PharoBootstrap that seems (git history) to be able to go back to Pharo 30. - I understand that at some point, Squeak and Pharo used to have the same VM. I have access to a squeak-vm 4.10.2.2614 in Guix, and I've seen this is in Pharo's ftp files, so I guess I can start there. What I need: - Some indication about the first version of Pharo that I'm able to build purely from squeak-vm, and where to find its source code (git+version or commit if possible, I seem to only be able to find its binaries currently in phero's ftp files). - Any useful information for early bootstrap steps. Some useful information on my side: - During the build process in Guix, we can't download data, so the entire bootstrap chain has to be explicited at once, hence the need to go back to the beginning in this case. Thanks in advance! -- Best regards, Nicolas Graves

Open Call: Object-Centric Breakpoints experiment
by Steven Costiou May 14, 2024

May 14, 2024

Dear Community, as part of a research project in the EVREF team, we are looking for people to participate to an empirical experiment on object-centric breakpoints - a debugging tool present in Pharo 9. Many people from the community already participated, and we thank them very much ð We are still looking for participants, we need 40 people to do the experiment! Please help us, in return it helps us understand better our tools and their impact and therefore build better tools for the Pharo community! For those who want to know a bit more, see my original email below. For those who just want to jump at the experiment, you can go there https://github.com/Pharo-XP-Tools/XPImageGeneration/tree/exp-ocd Thanks in advance ð Steven. --- We would like to invite you to participate to our experimental study on Object-Centric Breakpoints. This study aims to evaluate and to understand how Object-Centric Breakpoints impacts the debugging activity. This experiment takes place in **Pharo 9**. In this experiment, we ask you to solve 2 debugging tasks, one with standard Pharo tools and one other with Object-Centric Breakpoints. Between the two tasks, you will have to follow a tutorialand warmup tasks to learn how to use the tool. **How to Participate:** All instructions are here, please read them carefully: https://github.com/Pharo-XP-Tools/XPImageGeneration/tree/exp-ocd **About the Experiment:** The experiment last between 40 minutes and 2 hours. Participants should have experience with Pharo development and debugging. We recommend having more than 6 months experience in Pharo and debugging in general. You will gain insights into the Object-Centric Breakpoints approach and contribute to advancements in debugging research. Help us to build better debugging tools that help you debug! **Some constraints:** - You are not allowed to load external tools and baselines, but you can use anything that is in the base image - Please do the experiment in one shot if possible without interruptions - The experiment sends anonymous data to our inria server, please make sure that you have a valid internet connection - Please try to use the object-centric breakpoints when the experimental framework asks you to **Notes:** Participation is voluntary, and everything is anonymous. You can abandon the experiment at any point (and your data will be discarded). For any question, you can contact us: steven.costiou(a)inria.fr and valentin.bourcier(a)inria.fr Thank you for considering participating in our study. Your contribution will be valuable in advancing the field of debugging and helping us understand what tools we need to build for Pharo. Sincerely, Steven and Valentin, EVREF team, Inria
