Roassal 3d progress

by Alexandre Bergel

Hi! Milton, Ronie and I had a very fun programming session. Here some random screenshots during our programming session. Igor, would it be possible to have in the same window Athens and OpenGL? Maybe the question does not make sense, just I prefer the ask. On some point we would like to some popup in 2D above a 3D scene. All the examples are available on: http://smalltalkhub.com/#!/~ronsaldo/roassal3d You need to download first NBOpenGL to play with Roassal3d Cheers, Ronie, Milton & Alexandre -- _,.;:~^~:;._,.;:~^~:;._,.;:~^~:;._,.;:~^~:;._,.;: Alexandre Bergel http://www.bergel.eu ^~:;._,.;:~^~:;._,.;:~^~:;._,.;:~^~:;._,.;:~^~:;.

Then this workspace code should work: | enc encryptedString dkey decrString | key:='mySecretKey'. enc:=Blowfish encryptString:'12345678' with: key. encryptedString := enc asByteArray asString. Transcript show: ' encrypted: ', encryptedString; cr. decrString:=Blowfish decryptString: encryptedString with: key. Transcript show: ' decrypted: ', decrString; cr. But with the password 'test' it will always fail because I'm not yet padding the byte array to a multiple of 8 bytes before encrypting it.

Job: from Exceptions to Announcements?

by Martin Dias

Hi, I am looking into SystemProgressMorph and I found this flag in several methods: self flag: 'When we go from Exceptions to announcements, delete this and use show:from:to:during:'. I'd like to know more. I see that Jobs are implemented with both exceptions and announcements... what is the idea? to remove the exceptions and use only announcements? Thank you for your help, MartÃn

This is really nice. I hope it will reach people who develop webapps in ruby/php/java or whatever.

I don't know enough about PHP to really comment, but do you mean it would be (much) shorter ? I wonder and would certainly like to see. Just don't forget to include the full upload validation and parsing logic, as well as the default image. All lines of all files count: code, html, css, js, â¦ Anyway, the tutorial was not meant as a 'see how few lines we need'. I once did that in Reddit.st - In 10 elegant Smalltalk classes - Implementing a Reddit style web application in Smalltalk - Using Seaside, Glorp and PostgreSQL, but it is no longer available online, I should revive it.
