Looking for an engineer position to work on Virtual Machines
by Pierre Misse-Chanabier Oct. 25, 2022

Oct. 25, 2022

Hello, My name is Pierre Misse-Chanabier. I'm finishing my PhD in the RMOD team on testing Virtual Machines in about two months. I am therefore looking for a Job, hopefully in the Pharo community ! Ideally, I'm looking to work in the domains of Virtual Machines or Language Tooling, or Meta-programing, but I'm open to other opportunities. See my CV attached. I have to stay in Lille for at least the next year, therefore, I am looking to work remotely. Here are my most important projects and publications about them: Illicium : a framework to generate C code from Pharo code. Github repository: [ https://github.com/hogoww/Illicium | https://github.com/hogoww/Illicium ] IWST'19 Illicium: A modular transpilation toolchain from Pharo to C [ https://hal.archives-ouvertes.fr/hal-02297860/ | https://hal.archives-ouvertes.fr/hal-02297860/ ] version poster SAC'22 & full ICSR'22: Differential testing of simulation-based VM generators: automatic detection of VM generator semantic gaps between simulation and generated VMs [ https://link.springer.com/chapter/10.1007/978-3-031-08129-3_7 | https://link.springer.com/chapter/10.1007/978-3-031-08129-3_7 ] [ https://dl.acm.org/doi/abs/10.1145/3477314.3507171 | https://dl.acm.org/doi/abs/10.1145/3477314.3507171 ] Polyphemus: Retro engineering of the Pharo Image, and ease of VM tooling Github Repository: [ https://github.com/hogoww/Polyphemus/ | https://github.com/hogoww/Polyphemus/ ] Video Presentation for Esug Innovation award (I was unable to present it myself): [ https://www.youtube.com/watch?v=zf3cCtNW830 | https://www.youtube.com/watch?v=zf3cCtNW830 ] VMIL'22: Ease VM Level Tooling with Language Level Ordinary Object Pointers [ https://hal.inria.fr/hal-03827632 | https://hal.inria.fr/hal-03827632 ] (preprint) I am particularly interested in my latest work: Polyphemus.

Sponsoring our new mooc
by stephane ducasse Oct. 24, 2022

Oct. 24, 2022

Since more than a year we have been working on a new mooc called: âAdvanced Object-oriented Design and Developmentâ It will be quite good. We are bullet proofing it with a new lecture here at Lille. It will not focus on Pharo but on object-oriented design, tests, design patterns. It will present - Test and test-driven - Essential aspects of OOP - Basic and universal principles - Double dispatch - Case studies in Pharo - Some design patterns - Some coding idioms and we will composed of 8 modules Currently it has around 50 lectures and we expect around 60 + exercises. You can access some drafts of the support here: https://rmod-files.lille.inria.fr/?dir=DesignCoffeeClub <https://rmod-files.lille.inria.fr/?dir=DesignCoffeeClub> The production cost of this mooc is around 200 K Euros financed by Inria and it will be filmed in January. We hope to deploy it in April or May 2023. The mooc will be produced in english (and may be dub in french). It occurred to me in this difficult time to find good developers that some of you may want to sponsor this mooc\to get exposure. You can be associated with some of the best OO teachers: me, Guillermo Polito and Pablo Tesone. We have cumulated more than 40 years of teaching experience. Several books... Yes at the end of the day we should sale a bit our expertise - check below our track record with the previous mooc. As a sponsor you will get your logo and links on all the supports: Slides and videos. Note that this mooc is designated to have a live time of 10 years or more. It is teaching fundamental points of OOP. So this is a unique opportunity to market your company to people wanted to learn advanced OOP Note that there are no other lectures like this one. We have two levels of sponsoring: 2000 Euros for platinum sponsor 1000 Euros for plain sponsor Let us know. Just a little reminder of the previous Mooc on Pharo. It has more than 8 years. For the record, some youtube videos (that we published after 4 years of running the pharo mooc) got more than 6000 views and this is by developers. We got around 10000 followers not counting the people watching the mooc on youtube and here are some of the testimonies we collected over the years. J'ai trouvÃ© Ã§a trÃ¨s intÃ©ressant, beaucoup plus que prÃ©vu ! je regrette de ne pas m'y Ãªtre mis plus tÃ´t. J'ai enfin l'impression de vraiment faire de la POO ! Ou Ã l'inverse je me rend que je n'en faisais pas vraiment... - Anonymous, 2019 I have just completed week seven of the Pharo Mooc (beginner and object oriented tracks) I am starting a redo of the Mooc with the web track (TinyBlog project). I have already learned so much ! I have spent the last 20 years or so in software development and, following this Mooc, I realized I hadnât really grasped the essence of object oriented design. - Anonymous Â« Really one of the best mooc I have ever attended. And I have attended quite a few (openSAP, openHPI). As an old fashioned ABAP developer I want to be reborn as Pharo developer in my next life :-) Â» - Anonymous Hi! I finished the MOOC some weeks ago and I would like to congratulate everybody involved! After a decade+ of Python programming I think I found my new favorite language :). I'm making a small Teapot server for Slack command bots, I'm goona push it to Github (yay Iceberg), if anyone is interested. - EduardoPadoan I just completed the @pharoproject Mooc the best investment I have ever made of my time. MAQBOOL Hey all - I've just finished the Mooc - thanks for an excellent course and a thouroughly interesting look at a new way to program :smile: Looking forward to starting to play with Pharo on some upcoming ideas I've had. - Tieryn As much as I thought I understand object-orientation, it is very clear NOW that without a truly useable Smalltalk, which Pharo is, it is impossible to really understand and exercise object-orientation. Thank you all soooo much. - Mike D. 06/12/2020 I finished the Pharo MOOC a few days ago. Thank you very much to Damien, Stephane, and Luc for their work on the material! I enjoyed it very much - Anonymous Hey all - I've just finished the Mooc - thanks for an excellent course and a thouroughly interesting look at a new way to program :smile: Looking forward to starting to play with Pharo on some upcoming ideas I've had ð3 - Anonymous I already had previous Smalltalk experience, but yes, I'm extremely happy Chapter 7 has been extremely fulfilling - Anonymous A general comment I wanted to make is that the MOOC so far has been great. Impressed with the quality and content, and grateful that it is available and free. Many thanks! - Aryeh IMHO the videos were very well done. I would even say shockingly well doneâ¦ for a bunch of programmers who are supposed to be clueless about design - SeanDeNigris - 10/26/2017 The more I learning about @pharoproject the more I appreciate it's beauty and simplicity, finally, object-oriented programming is done right - MAQBOOL Mooc absolument remarquable. Superbe voyage autour de Pharo. Le paradigme objet qui (re)prend enfin du sens ! - Anonymous - 01/03/2019

Recommendation for password encryption?
by Mariano Martinez Peck Sept. 30, 2022

Sept. 30, 2022

Hi guys. Some time ago I asked about the best way to encrypt a password. Some of the recommendations I got was: 1) Generally for passwords you do not write a decrypt method for security purposes (eg you do not want people to be able to reverse engineer the encrypted password easily) 2) put a little salt 3) There is http://www.squeaksource.com/Cryptography/PasswordHashingFFI 4) I should not decrypt password but instead I should compare both encrypted versions to see if they are equal. My scenario is the following. I need to store database passwords in text files. So I don't want to let them as plain text. And while I understand 4), I think it's a different scenario than mine. I know that some database driver may allow you to directly send the encrypted password. But still...I have another similar scenario in which I have to store a password and then send it (unencrypted)...so I kind of really need a bi-directional encryption. Now..I would try to avoid having an external library + FFI. Any ideas what is the best thing I can do? And how could I solve 1) if I want bidirectional like in my case? Thanks in advance, -- Mariano http://marianopeck.wordpress.com
