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

[Pharo-project] About ~= and ~~
by Clara Allende Nov. 26, 2016

Nov. 26, 2016

Hi guys, I'm wondering, why? ProtoObject>> ~~ anObject "Answer whether the receiver and the argument are not the same object (do not have the same object pointer)." self == anObject ifTrue: [^ false] ifFalse: [^ true] Instead of: ProtoObject>> ~~ anObject "Answer whether the receiver and the argument are not the same object (do not have the same object pointer)." ^(self == anObject) not And why? Object >> ~= anObject "Answer whether the receiver and the argument do not represent the same object." ^self = anObject == false Instead of Object>> ~= anObject "Answer whether the receiver and the argument do not represent the same object." ^(self = anObject) not. Is there any particular reason for this that I'm missing?

Hi, maybe someone can help me out with this. Iâm working with ListModel that supports multiple selection and has autoDeselect turned off. Now Iâve tried to use #whenSelectionChanged: but it doesnât give any data, #whenMultiSelectionChanged: is not triggered at all, #whenSelectedItemChanged: works as for single selection list. Iâd be very thankful for any help. Uko

moving to Rubric in Glamour
by Andrei Chis Oct. 3, 2016

Oct. 3, 2016

Hi, I moved Glamour to Rubric, deprecated those presentations that use PluggableTextMorph and moved almost all usages of presentations that rely on PluggableTextMorph. These changes are still only in the Moose branch to see if there are any ugly bugs. The changes to the glamour API are the following: - deprecated #smalltalkCode, #pharoPlayground and #rubricText - added #pharoScript If you use #smalltalkCode replace it with either #pharoMethod or #pharoScript If you use #rubricTest replace those usages with #text If you use #pharoPlayground replace those usages with #pharoScript (we changed this as the glamour playground is not the same at the GTPlayground and this was causing some confusion) For this I also renamed GLMPharoPlaygroundPresentation to GLMPharoScriptPresentation and GLMMorphicPharoPlaygroundRenderer to GLMMorphicPharoScriptRenderer. If you are using the latest moose let me know if you run into any problems or have questions. Cheers, Andrei

ifTrue ifFalse shortcuts

Hi, was removal of ifTrue/ifFalse shortcuts on purpose, or by accident? https://pharo.fogbugz.com/f/cases/16125/Nautilus-doesn-t-recognize-the-cmd-… (maybe was caused by switch to Rubric?) Peter

I noticed the SmallPOS on ss3 is under MIT license. AFAIK, it was GPLv3. When did this relicensing happen? Stephan

Rubric mutability issue in RubTextComposer binary search
by Aliaksei Syrel March 5, 2016

March 5, 2016

Hi, seems like there is a rather rare bug in Rubric. I opened an issue with explanation: https://pharo.fogbugz.com/f/cases/15153/Rubric-mutability-issue-in-RubTextC… Would be nice to fix it until release. It was caught in Spotter - as it heavily uses multithreading. Any suggestions are welcome if it is known :) Cheers, Alex

Re: [Pharo-dev] [Pharo-users] World lastKeystroke and openInWorld: aPasteUpMorph
by Nicolai Hess Feb. 20, 2016

2015-06-11 10:58 GMT+02:00 Markus Schlager <m.slg(a)gmx.de>: > issues opened > I added a fix for the broken lastkeystroke,but this will only work for the ActiveWorld/PasteUpMorph, not for any other PasteUpMorph. With the split of PasteUpMorph in PasteUpMorph and WorldMorph, and the change of keystroke handling (KMDispatcher), there is more to do to make this fully work again - but I don't want to reintroduce the old keyevent handling just to make this work again. I would like to remove all the keystroke handling from PasteUpMorph/WorldMorph and use only KMDispatcher. Maybe there is another(new) way to make this "lastKeystroke"-demo? You can open a transcript and enable the KMLog (KMLog setDebug. Transcript open) It will log all(!) keyevents and print the matching keymapping actions. Or something like this: |m| m := Morph new. m openInWorld. m takeKeyboardFocus. m on:($r ctrl) do:[ m color:Color red]. m on:($g ctrl) do:[ m color:Color green]. m on:($b ctrl) do:[ m color:Color blue]. This will open a morph that changes its color on ctrl+r/g/b So, maybe we can remove the whole "lastKeystroke" handling and make demos/examples like the above one? > > Markus > >
