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

Progress Report -> Refactoring Project - ( May 24 - May 28)
by Evelyn Cusi Lopez May 31, 2021

May 31, 2021

Hi everyone, Last week I did these tasks: - Add the scopes list to the calypso browser (took longer than expected because it had to mimic the behavior of Calypso scopes to receive and execute queries). See the changes in the branch: DefaultScope <https://github.com/Lin777/pharo/tree/DefaultScope>. See the new behavior in the video: Youtube video <https://youtu.be/BV1qSw-Pgdc>. - Add settings option to select a default scope . See the changes in the branch: DefaultScope <https://github.com/Lin777/pharo/tree/DefaultScope>. [image: imagen.png] - Add an intermediate class between modal and dialog to be able to use modals as dialogs specifically in refactorings because these have a strange behavior to get user values (this pr is still pending approval in the Spec project). Check the changes in the PR <https://github.com/pharo-spec/Spec/pull/1079>. To fix issues: #9060 <https://github.com/pharo-project/pharo/issues/9060> and #5894 <https://github.com/pharo-project/pharo/issues/5894>. - Start to fix the rename instance variable refactoring in live objects (check the discussion in a forum <https://github.com/pharo-project/pharo/issues/8665> provided by *seandenigris* to guide me a little better) Tasks for this week: <https://github.com/pharo-project/pharo/issues/9142> <https://github.com/pharo-project/pharo/issues/9142> - Fix issue: RB - Improve instance variable refactoring #8665 <https://github.com/pharo-project/pharo/issues/8665> - Improve messages: No understable message #9229 <https://github.com/pharo-project/pharo/issues/9241> - Fix issue: RB - Inline all senders of class methods (instance creation) doesn't work, need improve pattern to search #9142 <https://github.com/pharo-project/pharo/issues/9142> - Add option to rename scopes of scope lists. - Fix issue: Push Method does not work when the method contains a super call <https://github.com/pharo-project/pharo/issues/9289> - Fix issue: preview default button should be apply <https://github.com/pharo-project/pharo/issues/9263> <https://github.com/pharo-project/pharo/issues/9241> Regards, Evelyn C.

Fuel projects, anyone?
by Max Leske May 28, 2021

May 28, 2021

Hi everyone, I was made aware that there actually *are* people who use Fuel :) I rarely get feedback, apart from the spare bug report, so I was thrilled to hear about people who use it actively or even have applications in production that rely on Fuel. To celebrate that (and boost my own ego of course...) I've added a "Projects using Fuel" section to the readme on GitHub and I'd love to see more entries in that list! So please let me know (or open a PR!) if you think your project deserves some exposure ;) Here's the link: https://github.com/theseion/Fuel. Stay awesome and positive! Cheers, Max

Open Sound Control Package for Pharo 9.0
by GÃ¼nter Khyo May 22, 2021

May 22, 2021

Hi, I have ported the Open Sound Control package to Pharo 9.0. Since the Catalog Browser is marked as legacy, I was wondering how to submit the patch. Is there a git repository? I attached the fileout to this email in case anybody wants to take a look at the package or knows how/where to add it to Pharo 9.0, Patch Note: OSC relies on the removed /RWTextOrBinaryStream/ class which has very specific behavior that I could not emulate using the available stream and codec classes, so I pulled in the class from Squeak 5, renamed it to OSCStream and added it to the OSC package. This seemed to be the easiest way to do it without changing the OSC implementation, but I welcome any suggestions for a cleaner solution. GÃ¼nter

Pharo Progress Report 19/05/2021 (The Return)
by Esteban Lorenzano May 19, 2021

May 19, 2021

Hello! The other day Torsten mention in discord that before was easier to follow what was going on due the reports we were publishing, and I think he is right. This reports stopped to being produced when the pandemic arise and lock-down was the norm... our organisation of work suffered and the reports were an undesirable victim :) I intend to resume the publication of weekly status reports, with a difference: focusing on immediate changes is not productive anymore because we have the excelent report of Marcus for that (which follows the integrations in Pharo development branch). So, I will talk about immediate and medium-term goals, and steps we are doing following them. This is the first, let's see if this helps people to follow :) Short-term goals: - Improve integration infrastructure for Spec2 and NewTools frameworks. - Improve quality and quantity of tests in Spec2 and NewTools frameworks. - Improve quality of class comments in Spec2 framework. - Since we are in freeze mode: fixing important bugs on Pharo9 and its components (this issue will stay here until release). Medium-term goals: - Removal of GTTools - M1 VM release - Release 9.0 # Last week work ## Last week: - moved newtools and spec infrastructure to github actions (travis was being slow) - fixed several bugs on SpGridLayout, SpDropListPresenter,SpTreePresenter and SpTreeTablePresenter - fixed wrong enable/disable dynamic and style of buttons (also in toolbars). - added some inspector extensions to improve visibility of Morph data - added a lot of tests to new Playground, SpCodePresenter, SpTreePresenter and SpTreeTablePresenter. - Pablo and Guille were working hard on improving the VM profiling infrastructure. - making the ARM simulator work - Working in the parallel execution of tests - Improving the stability of Socket primitives - Fixing problems in the Large Images support - Extending DrTest to delegate the UI construction to the plugins - Stef ported MethodWrappers to Pharo 9 (which allow a lot of profiling and "object centric" stuff. - Finally, Marcus was busy processing PRs and discussing future steps (in part with me ;) ) ## This week (as always, this is just pointing in a direction, what later comes in depends on the work load, problems, and "unknowns") - finish new infrastructure to improve integration speed of Spec2 and NewTools - add tests to new Inspector - more freezing actions (bugfixing, PR processing) cheers!
