Not a problem is a hacker starts with "I wonder what this button does?" rather than (like I would) "let me find the method called 'back'". frank

For browsing the references to an instance variable (or any other variable/global) I prefer Igor's idea: extend Cmd+Shift+n to search for any variables (instance, class, pool). Levente

Squeakfest Uruguay - Call for Papers
by Rita Freudenberg 27 Apr '11

27 Apr '11

The official Squeakfest website is now live and ready for you to propose a presentation, workshop, or panel. http://squeakfest.org The dates for Squeakfest Uruguay in Montevideo are May 26, 27, 28. The theme for this year's conference will be "How and why to use Etoys in the education" Our overall goal is to show how teachers are using Etoys to teach their full curriculum. Whether language arts, math, science, or more, we hope to showcase the many ways Etoys can help teachers demonstrate abstract ideas easily. If you've got experience teaching with Etoys, we'd love to hear about it, as would the attendees of the conference. We're also very interested in non-classroom Etoys use, particularly as it relates to OLPC pilots. We'll be adding more information to the website as it becomes available, but for now, the important thing is to get your presentation information to us so we can begin to design the program for our three days together. Please complete and submit the online form no later than May, 14th, 2011. Please share this information with anyone you think would be interested in either Squeakfest conference. We hope to see you there! Take care, Rita

You'll notice that the entire closure scheme is centered around this, in that temporaries that must outlive their dynamic extent for the correct working of blocks are either copied into blocks (as copied values) or stored into remote temp vectors, hence breaking any dependence on the temporaries in enclosing contexts. If you can live with this restriction then instead of stating "Cog doesn't copy the temps properly, so copy them here." in your reimplementation of copyTo: it would be more accurate to state "Cog doesn't preserve non-closed-over temps beyond their dynamic extent, so copy them here." or some such. Note that Cog /does/ preserve arguments. However, I've clearly still got some bug because look at the following. In the copy the arguments ba1 & ba2 (1 & 2) are in the wrong place on the stack. Sigh... [:ba1 :ba2| | context a b c d e | context := thisContext copy. a := b := c := d := e := context. { context. context copy } explore. { a. b. c. d. e } "This is here to avoid compiler complaints."] value: 1 value: 2 > > > Levente > > >> thanks! >> >> best, >> Eliot > > >
