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?

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

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 > >

missing cairo library in CI
by Peter UhnÃ¡k Feb. 14, 2016

Feb. 14, 2016

Hi all, not sure if this is best directed at pharo or CI mailing list... I've created a new job in pharo-contribution and my Pharo project uses Cairo library... however when CI ran the tests it failed on "Cannot locate cairo library. Please check if it installed on your system" ( https://ci.inria.fr/pharo-contribution/job/DynaCASE/2/PHARO=40,VERSION=deve… ) is it something I need to enable or disable somewhere? I'm pretty sure Athens also uses Cairo ( https://ci.inria.fr/pharo-contribution/job/Athens/) and it works just fine. Any pointers appreciated, Peter

[Pharo-project] [ANN] Pomodoro for Pharo 2.0
by Torsten Bergmann Feb. 5, 2016

Feb. 5, 2016

Hi, I followed the recent discussion and initial code about "Pomodoro" and since (until now) I used a timer written in Java I thought it would be a good idea to replace it with a Smalltalk one ;) I grabbed the HOPomodoro code from Phil and since it was marked as "experiment" I thought it would be good to write a new clean implementation with tests for Pharo 2.0. Thanks Phil - hope you are not angry that I hijacked the idea ... Attached is a screenshot of the tool. Install ======= Go to the Config browser in Pharo 2.0 ("Tools" -> "Config Browser") and load "Pomodoro" from the "Verified" tab. A new timer should appear and you can just click on "Start" to run the timer. When it finished it turns red, beeps and informs the user. How to use ========== You can open a new pomodoro (defaults 25 minutes) from the world menu ("Tools" -> "Pomodoro"). Customize ========= You can customize the pomodoro using Smalltalk. Here are a few examples: "open a new 25 minute one" Pomodoro new open "Opens a new timer with one minute total time" Pomodoro timerFor: 1 minute "Provide an action when pomodoro is finished" Pomodoro timerFor: 5 seconds whenFinishedDo: [ self inform: 'Pomodoro finished'] Code ==== The project comes with 15 tests. Code lives on project "Pomodoro" on SmalltalkHub. So far I added Phil and Sean as contributors since they discussed this topic already and may provide new ideas. If one wants to contribute feel free to do so. Thanks T.
