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

FFIIntegerTypes inheritance hierarchy
by Ben Coman Nov. 28, 2017

Nov. 28, 2017

I'm looking through the keyhole at something new to me, so maybe this is off base, but looking at the inheritance hierarchy... FFIIntegerType FFIUint16 FFIUint16 FFIUInt32 FFIInt32 FFIUint64 FFIInt64 FFIUint8 FFIInt8 I'm curious... why the all the Ints inherit from the UInts? Each of those classes has the same two methods #basicHandle:at: and #basicHandle:at:put. So the Int subclasses fully override the superclass methods. So there in no inherited behaviour on the instance side. On the class side, I see #externalTypeSize is inherited by the Ints, but evaluating... FFIIntegerType allSubclasses collect: [ :class | class externalType byteSize -> class externalTypeSize ] produces... 4->4 2->2 4->4 8->8 1->1 2->2 4->4 8->8 1->1 So naively the extra inheritance level seems unnecessary and perhaps having... FFIIntegerType class >> externalTypeSize ^ self externalType byteSize would allow the hierarchy to be flattened. Maybe not a great benefit, except to avoid the next person wondering the same thing :P Also, it is surprising that that FFUInt64 uses #signedLongLongAt: rather than #unsignedLongLongAt: . This seems on-purpose rather than accidental since its inherited by FFIInt64, so it seems there is something interesting to learn here that would benefit a method comment. cheers -ben

Layout in bloc
by Alexandre Bergel Nov. 25, 2017

Nov. 25, 2017

Hi! I am working on a popup support in Bloc and I am facing a problem. Consider the following code: -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= space := BlSpace new. space root layout: BlLinearLayout horizontal. 10 timesRepeat: [ | e | e := (BlRectangle new extent: 20 @ 20) asElement. e background: Color random. space root addChild: e ]. space root children withIndexDo: [ :e :index | e translateBy: (index * 30) @ 10 ]. space root children do: [ :e | e addEventHandler: (BlEventHandler on: BlMouseEnterEvent do: [ :evt | | txt | txt := BlText new position: evt position; fill: Color red; text: 'Hello World'. e parent addChild: txt ]). ]. space show -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= If you uncomment the second line (âspace root layout:â¦â), then the string hello world is added text to the element in which the mouse enter. With the layout, the string is added at the end of the line. I like very much the idea of having the layout applied when elements are added (even I suspect we may have scalability issues very soon), but in that situation, this is not wished.

Catalog statistics (Who know this projects?)
by Esteban Lorenzano Aug. 22, 2017

Aug. 22, 2017

Soâ¦ I took a couple of minutes to do a small list of project description status: >From a total of 379 projects currently in the catalog, just 115 have a description and/or keywords associated. Which means 264 are mysterious projects nobody can guess what are they about. I was thinking most of this projects would be in Unsorted (or Pharo 3), but I found that many are also on Pharo 5 and 4â¦. which is frankly unacceptable :) Even very important projects like Seaside or Garage and Glorp are not documented. So, please peopleâ¦ take a look at your projects and PLEASE, provide a description and proper keywordsâ¦ Nobody can guess what is Aconcagua (besides a cool mountain in south america), or Telescope, etc., etc., etc. Here the list of non-documented projects: http://smalltalkhub.com/mc/Pharo/MetaRepoForPharo50/main --- 'A4BP' 'Aconcagua' 'BootstrapMagritte' 'Chalten' 'CommandShell' 'Cormas' 'DependencyAnalyser' 'FamixJS' 'FontAwesome' 'Garage' 'GarageConnectionPool' 'GarageGlorp' 'Glorp' 'Grease' 'IniModules' 'Kendrick' 'Magritte3' 'MagritteMagic' 'MetaBoardBoard' 'MyFirstWebApp' 'NBOpenGL' 'NeoJSON' 'OSProcess' 'PetitParser' 'Phexample' 'Pier3' 'Pier3AddOns' 'ProcessWrapper' 'RewriteTool' 'Seaside3' 'SimplePersistence' 'Ston' 'Telescope' 'Woden' âXtreams' http://smalltalkhub.com/mc/Pharo/MetaRepoForPharo40/main --- 'AconcaguaDeluxe' 'AthensSVG' 'Autotest' 'CPanel' 'CreativeCommonsLive' 'DevFlow' 'EventRecorder' 'ExtendedNumberParser' 'ExternalWebBrowser2' 'FixedDecimal' 'Ghost' 'GraphViz' 'Gravatar' 'Hubcap' 'Infinity' 'Mandrill' 'Mathex' 'MemoryMonitor' 'MinimalConnectors' 'Mocketry' 'MongoTalk' 'NBSQLite3' 'NumericalMethods' 'ODBC' 'OSOSX' 'OSWindows' 'PackageDependenciesAnalysis' 'PharoLauncher' 'PlagueDoctor' 'Pomodoro' 'RemoteAnnouncement' 'SandstoneDb' 'Scheduler' 'ScriptManager' 'Shapes' 'SmallUML' 'Spreadsheet' 'Spy' 'StateSpecs' 'SuffixConditionals' 'Teachable' 'TestMock' 'Trees' 'Twilio' 'Vidi' 'VistaCursors' 'Viva' 'WiringPi' 'WorkingSet' 'XBase' 'sQuick' âsQuick_new' http://smalltalkhub.com/mc/Pharo/MetaRepoForPharo30/main --- 'Actalk' 'Arduino' 'BabyMock2' 'CTranslator' 'DBPedia' 'DigitalOcean' 'Forum' 'Fuel' 'GTDebugger' 'GTInspector' 'GTInspectorCore' 'GTPlayground' 'GTPlaygroundCore' 'GTSpotter' 'GToolkit' 'GlamourCore' 'GlorpDBX' 'GraphET' 'InstanceEncoder' 'Marina' 'Mechanize' 'Memcached' 'Moose' 'Pastell' 'PharoOnlineHelp' 'ProfStef' 'PythonParser' 'RFB' 'Roassal3d' 'SQLite3' 'Smallapack' 'SmalltalkHub' 'Snapshotcello' 'SortFunctions' 'Spotlight' 'Stamp' 'Tide' 'VersionBrowser' âVersionner' http://www.squeaksource.com/MetacelloRepository --- 'AXAnnouncements' 'Adore' 'Aida' 'Ajp' 'Algernon' 'Alien' 'Amers' 'Announcements' 'AutomaticMethodCategorizer' 'BetaNineIPAddress' 'CAnalyzer' 'CairoGraphics' 'CampSmalltalkLondon' 'Cecinestpasunepomme' 'CharacterMap' 'Chronos' 'CloudforkAWS' 'Cog' 'Connectors' 'ContextS' 'Control' 'Country' 'Countryside' 'DBXBrowser' 'DBXTools' 'DependencyBrowser' 'DependencyView' 'EnhancedOmniBrowser' 'ExternalIconFamily' 'ExternalWebBrowser' 'FileMan' 'FileTree' 'Filesystem' 'GemTools' 'Gitocello' 'Glamour' 'Gofer' 'GoferProjectLoader' 'GoogleAnalytics' 'HPDF' 'HealthReportProducer' 'HelpSystem' 'ICal' 'InstancesBrowser' 'JQueryWidgetBox' 'JavaScriptAnalyzer' 'Jejak' 'Keymapping' 'Kozen' 'KyotoTycoonClient' 'MaBase' 'MaClientServer' 'Magma' 'Magmafy' 'Magritte' 'Magritte2' 'Magritte3AddOns' 'MagritteAddOns2' 'Metacello' 'MetacelloBrowser' 'MetacelloPreview' 'MockGemStone' 'Mondrian' 'Money' 'MonticelloRedirect' 'Murmansk' 'Nagare' 'NativeBoost' 'Neo4reSt' 'NewECompletion' 'NewInspector' 'NewOCompletion' 'Nile' 'NotificationsArea' 'O2' 'OCompletion' 'OPAX' 'ObjectMetaTools' 'OmniBrowser' 'OmniBrowserLukas' 'Orca' 'PagedReader' 'Pharo' 'PharoMorphicExtras' 'PharoNonCore' 'Phriak' 'Pier' 'Pier2' 'PierAddOns' 'PierAddOns2' 'PostMark' 'ProcessModel' 'Quaternion' 'REPL' 'Raphael' 'RatPack' 'RefactoringBrowser' 'RefactoringTools' 'RoelTyper' 'SIXX' 'SPort2' 'SandcastleThemes' 'Scamper' 'Scribo' 'Seafox' 'Seaside' 'Seaside28' 'Seaside28Examples' 'Seaside30' 'SeasideJSON' 'SeasideRest' 'SeasideTesting' 'SharedWorkspace' 'Shout' 'SimpleApplescript' 'SoapOpera' 'SpellingServices' 'SpyForO2' 'Sqnappy' 'SqueakCheck' 'SqueakDBX' 'SqueakFS' 'SqueakSource' 'StOMP' 'Stripe' 'SunnysidePlanning2' 'SwaLint' 'Swazoo2' 'TODO' 'TimerDaemon' 'Tuio' 'VMMaker' 'Waterfall' 'WebClient' 'WebTester' 'XMLRPC' 'XMLSupport' 'Zodiac'

macOS Sierra support
by Sven Van Caekenberghe July 15, 2017

July 15, 2017

Hi, Can someone who really knows/understand please describe where to find the necessary Pharo VM's to run on the newly released macOS Sierra (10.12) ? In particular it seems old VM's just stop working and recent VM's that do work either have issues or cannot run older (3.0, 4.0) images. Thanks, Sven PS: I have not yet upgraded, but one of my colleagues did and he got stuck: even after we found a VM that worked, it could only run 5.0 images, not his production 4.0 images. Needless to say, this is not good. PS2: Another really annoying problem is the following: he saved all his (really important) scripts using Script Manager as a FUEL. Moving between 4.0 and 5.0 FUEL stops working (version incompatibility) - this is really not cool, why would a newer FUEL not be able to read older FUEL. He ended up copying string data by opening the binary FUEL file in a text editor.

Some test where Spur more slow than Cog
by Denis Kudriashov April 12, 2017

April 12, 2017

Hi. I found case where Spur more slow than Cog. Not much but. prototype := BorderedMorph new. result := [prototype veryDeepCopy ] benchFor: 2 seconds. In my computer I got: Cog: a BenchmarkResult(16,982 iterations in 2 seconds 1 millisecond. 8,487 per second) Spur: a BenchmarkResult(12,507 iterations in 2 seconds 33 milliseconds. 6,152 per second). Is it expected behavior for such case?
