Hi norbert I love the idea behind soil :) That you keep pushing it is just great. I will start to play with it during holidays.

Thanks for this. Sounds really cool. One thing I keep wondering about is the comment at ESUG that the serializer had to be rewritten from the ground up (no pun intended ha ha) because Fuel is neither flexible nor fast. Fuel has become such an integral part of the ecosystem that it seems a shame it couldnât help here. Was there any thought about modifying Fuel to make it more flexible and/or fast? Thanks again, Sean

Object-centric breakpoint experiment during ESUG'24

by Steven Costiou

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.
