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

Dear World and dynamic language lovers: The time has come for Pharo 9 (https://pharo.org/) ! Pharo is a pure object-oriented programming language and a powerful environment, focused on simplicity and immediate feedback. Here are the key features of Pharo 9: Full redesign of the Spec UI framework (new logic, application, style, GTK3 back-end) New tools: new playground, new object centric inspector, new object centric debugger. better and new Refactorings class comments are now written in Microdown format (Markdown compatible) classes now can be defined using a "fluid" api (Preview) New completion framework that adapts better to edition contexts and is customizable Fast universal non-blocking FFI which now uses libFFI as backend. Pharo now supports Windows, OSX, Linux (Ubuntu, Debian, Fedora, openSUSE, Arch, Raspbian) and multiple architectures (Intel/ARM 32/64bits). Virtual Machine Idle VM Support for ARM 64bits Support for Apple M1 More than 3000 tests Built for Ubuntu 18.04, 19.04, 20.04, 21.04, 21.10; Debian 9, 10, Testing; Fedora 32, 32, 34; openSUSE 15.1, 15.2, Tumbleweed; Manjaro; Arch Uses SDL 2.0 as back-end by default.

A more extended changelog can be found at https://github.com/pharo-project/pharo-changelogs/blob/master/Pharo90Change….

Luancher - Stable Pharo 9-based Release?
by sean＠clipperadams.com July 29, 2021

July 29, 2021

Is there a stable Launcher release based on P9? If not, is there a timeline? The zip bug in P8 means that Launcher often goes over Macâs open file limit and the workaround is a PITA (requires sudo, etc).

Updates from the trenches...
by stephane ducasse July 28, 2021

July 28, 2021

Hello community Just a little mail from holidays to let you know that from September on we will try a new organisation. Pharo 9 (with Covid and amount of work) was stressful for us. Seriously we deliver more than expected so we did several meta meetings (and we will continue) to understand how we can work with less stress. In particular we want to be able to give better feedback to the community while being able to deliver the large items we have on our plate. In a nutshell every month we will have - a full working day around - design ideas such as https://github.com/pharo-project/pharo/wiki/01-PhIP-Simplify-Pragma-Storage - new tools such as MethodProxies to look at our lovely system in different ways https://github.com/pharo-contributions/MethodProxies - code review - a full internal bug/issue internal sprint we want to be able to concentrate on issues that require concentration and we want to make sure that we can provide feedback and integrate PRs that need brain. - our monthly open sprint (we hope that Covid 4th wave will not break our fun once again).

FileLocator uninitialised ?
by Sven Van Caekenberghe July 23, 2021

July 23, 2021

Hi, It seems that in the latest Pharo 9 (downloaded minutes ago) the following: FileLocator desktop resolve. Pops up a dialog asking to set the location of {desktop} manually. I am guessing FileLocator did not properly initialise at startup. It seems it is missing from the session manager. This is bad. Maybe the full list of classes that are supposed to be part of the session manager's start up sequence need to be checked. Such a failure to initialise are sometimes hard to find and can lead to subtle bugs. Sven
