In the left the inspector display all the items in the bag ( it's right ) In the right the inspector display the relative Occurences, but some are set to 0. Because ?

Works marvels indeed. I have made some more Seaside integrations for this one. But Pharo3. Need to upgrade to latest Seaside and Pharo.

Data Encryption

by sergio ruiz

I have been tasked with throwing together a small web app that will hold the passwords to different projects for my company. I would like to use seaside to do this, but the biggest requirement is that we need to be able to either: - encrypt the entire database, so that if the machine was compromised physically, the data would be useless. or.. - encrypt the username and password fields to facilitate the above, also. i am thinking that the first option might be easiest to implement. any ideas on how i would pull this off with pharo?

Equality and hash

by Trussardi Dario Romano

Ciao, i works with Pharo 4.0 environment. I have a class Product with some instance variable and the = method set to: = anItem anItem ifNil:[^false]. anItem class = self class ifFalse:[ ^false]. ^ rfrConsegna = anItem rfrConsegna and:[ rfrSubTable = anItem rfrSubTable and:[ rfrDcm = anItem rfrDcm and:[ indexRiga = anItem indexRiga and:[ referenceTime = anItem referenceTime and:[ consumer = anItem consumer and:[ item = anItem item and:[ opzioniVoce = anItem opzioniVoce ]]]]]]] Some of these variables are instances of classes with specific implementation and some variables themselves. I set the relative hash method to: hash ^ rfrConsegna hash bitXor:( rfrSubTable hash bitXor: ( rfrDcm hash bitXor: ( indexRiga hash bitXor: ( referenceTime hash bitXor: ( consumer hash bitXor: ( item hash bitXor: ( opzioniVoce hash ))))))) Now when add some setup instances of class Product to a bag, the relative inspector report some aProduct entry but with some Occurences of this set to 0. aProduct1 3 aProduct2 0 aProduct3 0 Some consideration about it ? Some references about hash implementations ? Thanks, Dario

In the contrarty, I had the felling that Pharo4 configurations were mixing old and new, and of course it brings problem. Hilaire -- Dr. Geo http://drgeo.eu

Voyage needs a newer Grease, is that backwards compatible (I forgot)? Stephan
