Epicea wishlist

by Stephane Ducasse

Hi martin I'm missing two features: - keep the filter across session because this is boring to have to redo them all over. - a search for entities accross session. - a search inside a session For example I was looking for all the changes I did to the UI part of my application but I was doing many development loading different unrelated package and saving after. Right now you can restrict to view changes but only if you have a first entity of the package for example so you have to look first is there an entity of this package. Stef

Let's prepare for Google Code-In 2017 with Pharo Consortium

by Jigyasa Grover

Hello Pharo-ers ! On behalf of the community, I would like to thank each one of you for their significant contribution in the recently concluded *Google Summer of Code 2017* with *Pharo Consortium*. We aspire to take-off on a long flight after this successful stint. In this spirit, I proposed at ESUG 2017 that we take part in the upcoming *Google Code-In 2017*. GCI is a contest to introduce pre-university students (ages 13-17) to open source software development. Because Google Code-in is often the first experience many students have with open source, the contest is designed to make it easy for students to jump right in with /bite-sized tasks/ (3 to 5 days) having categorised as: Code, Documentation/Training, Outreach/Research, Quality Assurance, or User Interface. Students search for a task from the list created by us that interests them and claim it. They have at least three days to complete it. The student works on the task, getting guidance from mentors, if needed. Once the student is ready, they submit their work for review through the contest website. Mentors from the organisation evaluate the work, provide feedback, and if it's complete, accept it so that student can claim a new task. Otherwise, specific feedback is provided, and the student goes back to improving it. Participants who complete at least 1 task get a digital certificate. Participants who complete 3 or more tasks receive a t-shirt too. At the end of the contest, each organisation chooses five finalists to receive limited edition Google Code-in hoodies. Two finalists from each organisation get to be the grand prize winners and go on a trip to Google Headquarters in California ! The contest runs for about 6-8 weeks in December & January generally. With organisation applications beginning in October/November, we need to be well prepared for this seasonâs application with a hope to get selected. As an open source evangelist and a Pharo developer, I would like to invite all the experienced members to be a part of the "GCI with Pharo Consortium" Team and mentor students. To get added to the âprivate repositoryâ (we need to keep prospective students away from the task list before the program begins ð ) where you can put in your tasks/suggestions kindly EMail me or any of the previously added mentor. Looking forward to an appreciable representation from the Pharo community.

Maybe it is unique enough that it would need its own mailing list at some point.

I am definitely interested in this. I am interested in arrays of numbers and doing calculations on those numbers. I was thinking that I would be needing to code this in C and call from UFFI. I read your message and I thought that it meant I could code in Lowtalk and then call the new library via UFFI. So, what I understand here is that I can code in Lowtalk for the Lowcode backend and not require UFFI? At least at some point in the future. That sounds awesome. > I want to use Lowtalk in Woden 2 exactly for the second use case. > Currently in Woden 2 I am using the language described in the Lowcode > paper.

Ok. I was confused in my brief look at GitHub as to whether we were programming in the image on with a text editor. It would be nice if at some point it could be done from the image. Even if it is a with a new editor (possible from the new moldable work) understanding Lowtalk and tools to do compilation. Possibilities are interesting. Thanks again.
