I get my pharo on ubuntu 14 64 bit with cd Ephestos; wget -O- get.pharo.org/alpha+vmLatest | bash looks like startup scripts on ubuntu has been broken StartupPreferencesLoader preferencesGeneralFolder . returns nil, looking inside the method's source if I do FileLocator preferences asFileReference gives me a nice error Cant find the requested origin trying with cd Ephestos; wget -O- get.pharo.org/alpha+vm | bash for getting the stable default vm, same problem, so I assume this is an image problem here is the stack UnixResolver(PlatformResolver)>>cantFindOriginError [ self cantFindOriginError ] in UnixResolver(PlatformResolver)>>directoryFromEnvVariableNamed: in Block: [ self cantFindOriginError ] [ ^ aBlock value ] in UnixResolver(PlatformResolver)>>directoryFromEnvVariableNamed:or: in Block: [ ^ aBlock value ] BlockClosure>>cull: Context>>evaluateSignal: Context>>handleSignal: Error(Exception)>>signal Error(Exception)>>signal: Error class(Exception class)>>signal: FFICallout>>loaderForArgNamed: FFICallout>>loaderForArgNamed:indirectIndex: FFICallout>>argName:indirectIndex:type:ptrArity: FFIFunctionParser>>parseArgument FFIFunctionParser>>parseArguments FFIFunctionParser>>parseNamedFunction: FFICalloutMethodBuilder>>parseSignature: FFICalloutMethodBuilder>>generate FFICalloutMethodBuilder>>build: FFICalloutAPI>>function:module: UnixEnvironment(Object)>>ffiCall:module: UnixEnvironment(OSEnvironment)>>getEnv: UnixEnvironment(OSEnvironment)>>at:ifAbsent: [ Smalltalk os environment at: aString ifAbsent: [ nil ] ] in UnixResolver(PlatformResolver)>>directoryFromEnvVariableNamed:or: in Block: [ Smalltalk os environment at: aString ifAbsent: [...etc...

Nu we toch Nederlands mogen praten, het lijkt me best om voorbeeld code zo minimaal mogelijk te houden. De paswoord hashing is wel een goed idee. ;-)

This is a bug I wasn't aware of. Thanks for reporting it. I'll have a look. But, even if we fix it, don't expect morphs to work on JS. PharoJS doesn't support graphic primitives... at least not in the near future :-) Noury

Too bad JPMorgan didn't stick with Smalltalk. It seems that most of the big success stories come from the 1990s and perhaps early 2000s. It would be *real nice* to have a big success story from the last 10 years; otherwise, it's hard to counter the notion that Smalltalk is hardly used any more. Given what I have to work with, I could only come up with this <https://medium.com/smalltalk-talk/who-uses-smalltalk-c6fdaa6319a> . It's a little apologetic, but what can I do? Esteban A.
