Re: [Pharo-users] [Pharo-dev] [ANN] XML Metadata Interchange (XMI) for Pharo

by Peter Uhnak

We spoke briefly on Tuesday. I need to take a look (also at his EMF generator) and see how the tools could benefit from each other. I think it could simplify some of my code or streamline the use of it. (Also I have about a billion code generators at the moment with small differences... so I will merge that at some point too...)

Fwd: Welcome to GSoC 2017!

by Serge Stinckwich

Dear all, please find below more information about the GSOC 2017 program. Among the changes for 2017 that we should pay attention, two are quite important: - Students can only be accepted into GSoC 2 times. Google Admins will do a sanity check on all accepted students once you select your students in late April so you do not need to be concerned about this. - If you are a university, we expect you to select students outside of your program. Selecting students from your university is okay but if *all* of the students you select are from your university then you likely wonât be accepted into GSoC again. I will ask for the last item, because I dunno if they are talking about the Pharo org or the mentors. Regards, ---------- Forwarded message ---------- From: Google Summer of Code <summerofcode-noreply(a)google.com> Date: Thu, Mar 2, 2017 at 12:15 AM Subject: Welcome to GSoC 2017! To: sergestinckwich(a)gmail.com [image: Google Summer of Code] Hi Serge Stinckwich, This year marks our biggest program ever! We have 201 open source organizations participating in GSoC 2017 and we expect to accept more students than ever before as well. And welcome to 37 organizations participating in their first GSoC! Right now you should be chatting with proactive, excited students. Remember to keep your Ideas List updated and make it clear and simple to understand so students can easily find your Ideas - if it requires multiple clicks to get to the Ideas List that is not ideal. We want to give you a quick overview of the next few months and address some of the common questions you may have these first few weeks of the program. *New changes (and some reminders) for 2017* - There are 3 evaluation periods this year where mentors are required to complete an evaluation of their student. After the first 4 weeks of coding, after 8 weeks of coding and then at the end (after 12 weeks of coding). The evaluation forms are shorter than previous years so they should take less time to complete. - Students can only be accepted into GSoC 2 times. Google Admins will do a sanity check on all accepted students once you select your students in late April so you do not need to be concerned about this. - If you are a university, we expect you to select students outside of your program. Selecting students from your university is okay but if *all* of the students you select are from your university then you likely wonât be accepted into GSoC again. - New org payment system using Payoneer. We are no longer requiring OAs to register for a Google supplier account and instead orgs will do what students do and create an account with Payoneer. This will allow for orgs to receive payments *much* faster, with orgs receiving their stipend payments in September. (more details to come in May) - We are now allowing 13-17 year olds to be mentors for GSoC as long as they have parental consent to be a part of the program. An additional form is required. *Inviting Mentors to your Organization* Organization Administrators should be reaching out to mentors and sending them invitations to be a part of their organization. The mentor will then click the link in the email they receive to create their account. PLEASE NOTE: Right now first time mentors should wait a few days to register until we have announced that we have fixed a small validation error on the site not allowing mentors to choose â0â as an option to the question âHow many times have you participated as a GSoC mentor previously?â They canât edit that field once they put a number into it and we are trying to get a good idea of how many new mentors we have each year. Thank you for your patience. *GSoC Mentor-invite Mailing List* For those that have opted into the GSoC mentor mailing list (available on your profile page) we will bulk add you to the list on March 6th. Then we will add additional folks who opt in about once a week throughout the program period. You can remove yourself through the groups interface at any time. You can also update your settings to receive a daily digest of emails and other options. This generally is not a very high traffic list but there will be more questions over the next two months on this list than probably later in the program. The GSoC mentor mailing list is a great way to ask questions of other org admins and mentors and to get their feedback and help. *Important Upcoming Dates* *Now - March* *20:* Proactive students will reach out to you and ask questions about your ideas list and receive feedback from your org so they can start crafting their project proposals. *March 20 - April 3 16:00 UTC*: Students will submit their draft proposals through the program website for you to give solid feedback on. *April 3 - 16:* Review all submitted student proposals with your org and consider how many you want to select and how many you can handle. Decide on the minimum/maximum number of student slots to request. *April 17, 16:00 UTC*: Deadline to submit slot requests (OAs enter requests) *April 19, 16:00 UTC*: Slot allocations are announced by Google *April 19 - 24 16:00 UTC* : Select the proposals to become student projects. At least 1 mentor must be assigned to each project before it can be selected. (OAs enter selections) *April 24 - May 4:* Google Program Admins will do another review of student eligibility *May 4*: Accepted GSoC students/projects are announced *May 4 - 29*: Community Bonding Period *May 29*: Deadline to notify Google Admins of an inactive student that you wish to be removed from the program *May 30*: Coding begins *June 26-30*: First evaluation period - mentors evaluate their students and students evaluate mentors *July 24 - 28*: Second evaluation period - mentors evaluate students, students evaluate mentors *August 21- 29*: Students wrap up their projects and submit final evaluation of their mentor *August 29 - September 5*: Mentors submit final evaluations of students *September 6*: Students passing GSoC 2017 are announced *More Information* If you have not yet read the Roles and Responsibilities <https://developers.google.com/open-source/gsoc/help/responsibilities>undefined page created with the help of GSoC Org admins and mentors, we highly encourage you to read this and share it with your prospective mentors - it will help everyone understand what is expected of them over the next 6 months. You may also want to check out the Mentor Manual, which contains important information for both Mentors and Org Admins at each stage of the program.

I'm interested by a firmata client protocol or why not a solution to program an Arduino directly from Pharo. > Hi Olivier, You probably have a few of these references, but since you don't mention which you have, I'll list what I found from a quick sweep... I read [1] that the Firmata protocol "uses the MIDI message format." Pharo seems to have removed the MIDI related code after it forked from Squeak. Squeak still has it. Download 5.1 from http://squeak.org/downloads/ Then go World Menu > Open > Method finder Type midi <Enter> and browse the code. Pharo and Squeak share a VM, so this should be compatible with Pharo. You'll see a few of the primitives located in classes SimpleMIDIPort and MidiPrimTester in the System-SerialPort package. Note, some of the primitives that show no references/implementors in the right-side pane, need to be right-clicked to choose Senders to see the implementation, since the method name is different to the pragma name. Then there is http://www.squeaksource.com/Arduino.html which may or may not need to MIDI code from Squeak. This code is circa 2013 so the (optional) FFI parts may need updating for Pharo UFFI. There is http://smalltalkhub.com/#!/~juanmanuelvallejos/gcodewithfirmata "It is an implementation of the protocol firmata in smalltalk. And also it contains a parsing to G code for cnc machines." There is http://smalltalkhub.com/#!/~Citilab/Snap4Arduino/ circa 2014. There is http://smalltalkhub.com/#!/~JohanBriglia/ArduinoIO circa 2016, but probably not what you want being a "Simple program to connect easily pharo and the arduino via serial port Uses a Python program and terminal commands via CommandShell" There is http://smalltalkhub.com/#!/~JLaval/Arduino circa 2016, and the commits show PhratchArduino-janniklaval.9 Phratch is available here http://www.phratch.com/ Its based on Pharo 4, but seems the most current. Reading here... https://groups.google.com/forum/#!topic/phratch/C6IYZ-TDt50 perhaps the most efficient path would be buying Jannik an Arduino to test on (if indeed Phratch uses the firmata protocol as you require). cheers -ben [1] https://github.com/firmata/protocol/blob/master/protocol.md
