by HernÃ¡n Morales Durand

For Nautilus I've read a review blog post at http://marianopeck.wordpress.com/2012/02/26/nautilus-the-reborn-of-the-syst… I didn't found anything else, maybe I'm missing something? I've installed Nautilus with the following script in a clean Pharo 1.4 core Gofer it url: 'http://ss3.gemstone.com/ss/Nautilus'; package: 'ConfigurationOfNautilus'; load. (Smalltalk at: #ConfigurationOfNautilus) perform: #loadRelease but after some random clicks I've received a SubscriptOutOfBounds exception. I've attached the stack from the debugger and a screenshot.

Re: [Pharo-users] [ANN] ZTimestamp

by Paul DeBruicker

Yes I agree there's a need for speed. I think ZnTimestamp is a valuable addition. And maybe the primitive that returns ms since epoch and offset gets adopted so DateAndTime can be nearly as fast.
