Looking for new adventures
by Koen De Hondt July 12, 2024

July 12, 2024

Dear Pharo Community, As you may have read on my blog <https://all-objects-all-the-time.st/#/blog/posts/1> or heard during my ESUGâ23 presentation, eighteen months ago I entered the Pharo scene after being away from the Smalltalk community for 20 years. For the last one and a half years, I have been a member of a team using Pharo and GemStone. I attended almost all Pharo Sprints in Lille (every last Friday of the month). In this channel, I have informed you about my intention to build a new browser based on Spec. That development has been on the back burner for the last five months because I have been working hard with StÃ©phane Ducasse to finish the book âApplication Building with Spec 2.0â. I have presented at ESUGâ23, and I am sad that I could not attend ESUGâ24 this week. >From the above, my contribution to the Pharo community is clear, and I think my drive to contribute more is also clear. In a few months, I will leave the team I am working with now. Therefore, I am looking for new adventures. If you are looking for a seasoned software developer who likes working in Smalltalk/Pharo very much, please send me a message, and I will be in touch rapidly. Please find more details on my career history on LinkedIn <https://www.linkedin.com/in/koendehondt/>. Best regards, Koen

[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

Object-centric breakpoint experiment during ESUG'24
by Steven Costiou June 24, 2024

June 24, 2024

Dear community, First, I would like to thanks again all the participants to our experiment with object-centric breakpoints in Pharo. Many people participated, and we plan to present our results in an informal manner at ESUG. However, from the scientifical point of view it would strenghten our analysis if we had more participants. The more participants we have, the more we can trust our results and take enlightened decisions about how to further develop the object-centric debugger. Therefore, the experiment remains open until July 10th (included). If you're interested you can still do it, the instructions are here https://github.com/Pharo-XP-Tools/XPImageGeneration/tree/exp-ocd Many people also declined to participate because of a lack of time, which we totally understand. This is why we also propose to you, if time is an issue, to participate to the experiment during the first days of esug. We can find a calm room in which we can supervise the experiment and collect your data (reminder: once in our server the data is anonymized). Please let us know if you would be potentially interested to participate in such setting during ESUG. Thanks in advance, Steven and Valentin, EVREF team.
