[ANN] Cheer for THE Medusa - the single Smalltalk based battle snake
by Jerry Kott April 25, 2020

April 25, 2020

Hi lists, you may recall a mention of Battlesnake in these forums before. Today, the Battlesnake team is holding an online tournament that you can watch live on Twitch: https://www.twitch.tv/battlesnakeofficial <https://www.twitch.tv/battlesnakeofficial>. My entry THE Medusa is the only Smalltalk-based battlesnake in the competition. It’s listed in the Group D of the Veteran division. Not sure when it’s going be on - currently the Rookie division is playing. I hope you can join, watch, have some fun, get inspired to write and enter your own Smalltalk based snakes for future competition (the arenas are open year-round so you have plenty of time to test your snakes), and if you can, donate a small amount to Food Banks Canada in support of families affected by COVID-19. Cheers, stay safe & stay healthy. Jerry Kott This message has been digitally signed. PGP Fingerprint: A9181736DD2F1B6CC7CF9E51AC8514F48C0979A5

Participate to the Magic Literal XP
by Stéphane Ducasse April 21, 2020

April 21, 2020

Dear all, We are running a large XP for a research around Magic Literals. A magic literal is a literal (number, booleans,…) that is used to denote something but that it not immediately obvious to the code reader: it can be for example a number but could be also a string, a character or boolean (this is what we want to discover). When you read the code you should be puzzled by the usage of this magic encoding and this is what we want to understand and that you report to use using a special tool. Now identifying magic literal is not easy and we want to measure them. We already did a publication at ESUG last year (but we only did an XP with 100 methods) and now we want to go the world. If you want to read it https://hal.inria.fr/hal-02266137/document Our idea is to have result first in Smalltalk and then, only then check with Java :). But for that we should show to the world that we did a large XP. So we build one and now we need you to help. First we need to evaluate the situation and understand the different cases, as not all literals are "magic". You can help us in this. It can take you 30 min for one experience. In the shared directory https://www.dropbox.com/sh/ag94vutsrtcs0n9/AAAEkpB2onlWpcFLqLPKOpOaa <https://www.dropbox.com/sh/ag94vutsrtcs0n9/AAAEkpB2onlWpcFLqLPKOpOaa> there are images for different experiments (on whole Pharo, on Roassal, Polymath, VM maker, Seaside project, …) We want to compare the analysis of an expert and an external person on a domain this is why we will cross comparison between roassal expert and roassal newbie (same for Seaside, Polymath, VMMaker) These images contain the code and the tool for the experiment and they should be open with Pharo80 you can get from http://www.pharo.org To participate in the experiment: - Step 1. go to the document https://docs.google.com/spreadsheets/d/1DrjXcfuR8Ja_7luknUUfijO8wzYYaJ2ZP_p… <https://docs.google.com/spreadsheets/d/1DrjXcfuR8Ja_7luknUUfijO8wzYYaJ2ZP_p…> - Step 2. select one experiment to do (for example put your name in the column 'Doing’) add your expertise to the sheet - Step 3. please select the experiments in numerical order, e.g. do the Pharo-1 experiment before the Pharo-2 one. Note that a Lot will contain also some other methods because we are mixing methods to collect more information so do not be surprised to see other methods that Polymath’s ones in the polymath XP. - Step 4. Get the tool on the experiment. >From the list grab an inspector and execute MLSExperimentPresenter openOnSample: self ' with the batch you chose as argument You should get the following tool (with different colors :) - yes that theme is funky) . - Step 5. decide whether each literal presented is Magic or not (unabling ‘Hide completed' can help) Remember: 'A magic literal is a literal (number, booleans,…) that is used to denote something but that it not immediately obvious to the code reader' - Step 6. completing one experiment should take less than 30 minutes - Step 7. when done, save the result (button at the bottom of MLSExperimentPresenter) - this will give a STON file named after your batch. - Step 8. You need to send us this file (email at nicolas.anquetil(a)inria.fr <mailto:nicolas.anquetil@inria.fr>) Your identity will be discarded from the data (anonymous answers). But we will owe you a beer at ESUG or Pharodays :) We will use it only to assess your expertise in Pharo and/or the project evaluated. Many thanks for your help in improving pharo and our understanding of the literals (magic or not) Nicolas, Stephane, Julien, Christopher and Oleksandr -------------------------------------------- Stéphane Ducasse http://stephane.ducasse.free.fr / http://www.pharo.org 03 59 35 87 52 Assistant: Julie Jonas FAX 03 59 57 78 50 TEL 03 59 35 86 16 S.

My *personal* take on this is is that we can migrate easily the catalog, without deprecating it: - the catalog repositories will stay alive as read-only, so it will be no problem to access old catalog entries (unless they depend on private projects, but that would be odd) - a low-energy solution for this is to migrate these repositories to squeaksource3. This should be mostly straight-forward. - a high-energy solution is to rethink the catalog. I know there have been some community efforts from Christophe Demarey for example, Esteban has also interesting ideas on how to attack this.

[ANN] SmalltalkHub Deprecation Notice
by Guillermo Polito April 3, 2020

April 3, 2020

SmalltalkHub Deprecation Notice SmalltalkHub is now getting old and it is time to deprecate it. We plan to replace it by a static file server during 2020. The public data will still be readable and consumable from monticello clients, but modifications will not be allowed in the near future. SmalltalkHub users should move their projects to git repositories or other monticello repository services. What is changing? If you currently host a project in SmalltalkHub, you should migrate your projects to another platform as soon as possible. If you depend on a project hosted on SmalltalkHub, you should contact the owner of that project to schedule a migration. If you have documentation or tutorials using SmalltalkHub, we recommend to update those after a migration. An archive of all public projects in SmalltalkHub will be made available in read-only mode. This archive will be readable through monticello clients for compatibility reasons. Private projects, due to privacy reasons, will not be published in the public archive and will be removed to protect their owners. Why are RMoD and Inria making this change? SmalltalkHub has finished its cycle. The arrival of git integration in the past years caused the move of most users in the Pharo community to git hosting services. They now use exclusively other platforms. Furthermore, RMoD and Inria lack the manpower to properly maintain the SmalltalkHub service and keep it up to date. Smalltalkhub has no added value compared to other code source hosting platforms. How much time do I have to adapt to this change? The SmalltalkHub deprecation will follow the next timetable: Monday 04 of may 2020: SmalltalkHub will be read-only. Creation of new users and projects will be forbidden. New commits will be rejected. All existing users, projects (public and private) and their commits will remain available and visible, but their settings will become read-only. Monday 02 of november 2020: SmalltalkHub will be migrated to a static file server archive. Private projects and their commits will not be available anymore. The RMoD team and Inria plan to keep the static file server alive for, at least, 5 years from the date of its creation. What will happen if I do nothing? Your public projects will become read-only and you will not be able to commit anymore. Your private projects will become unavailable. What alternatives do I have? Those wanting to keep using monticello can migrate their projects to other monticello hostings such as http://squeaksource.com <http://squeaksource.com/> or http://ss3.gemstone.com <http://ss3.gemstone.com/> Those wanting to migrate to git, Peter Uhnak’s git migration tool (https://github.com/peteruhnak/git-migration <https://github.com/peteruhnak/git-migration>) automates monticello to git migration in tonel format. Cheers, Guille on behalf of the RMoD team
