[ANN][Squeak-dev Images] July 2008 versions
by Damien Cassou 03 Jul '08

03 Jul '08

Hi, I've just uploaded new squeak-dev and squeak-web images based on Squeak3.9.1-7075, Squeak3.10.2-7179 and Pharo0.1-10046. More information and download: http://damien.cassou.free.fr/squeak-dev.html Changes in this version: --------------------------- - The 3.10 images are now based on 3.10.2-7179. - Pharo images are based on version 10046. - Rio is now part of the non-beta images too. - Algernon has been reintroduced as a beta package and it does not slow down the loading phase anymore. - OB-Enhancements has been updated too. Here is a comment from its author David Röthlisberger: "This one should be fairly stable. The delta to the previous version is mainly bug fixing, some minor corrections, and some new icons added." - OB-Refactory saw important fixes too. Is this list of changes useful to anyone? If not, I can remove it.

presentations, projects, tabbed interfaces, and paper as a UI metaphor
by Brenda 03 Jul '08

03 Jul '08

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Quick summary of a long email: I have a couple of months free, which I am thinking of spending writing or helping write some classes that let me treat Squeak as smart paper. To me, this seems related to BookMorph and its subclasses and rewrites, how Projects are treated, and how people give presentations using Squeak. Right now, I am looking for other people who care about this idea or have requirements that should affect the solution, related code that already exists, and collaborators. I don't have set requirements or design notes yet but will send them here for review when I (hopefully we by then) do. Several things have been bouncing around in my head lately: - - I recently resumed work on an application with a tabbed interface which I wrote a couple of years ago. Back then, I rewrote a subset of BookMorph and TabbedPalette to support this since they weren't doing what I wanted and were too crufty for my refactoring skills at the time, but lately I've been thinking about Ned Konz' exhortation to extend others' existing packages vs. write new ones from scratch. - - Also a few years ago, I gave a presentation of an early version of this tool using a StackMorph. It was frustrating to set up despite the very useful tutorial, and very embarrassing when the floating controls disappeared on the second slide, so I couldn't advance to my demo. I see a couple of new options on SqueakMap (one of which is also a BookMorph rewrite) now. - - I've been using OneNote on my Tablet PC, which is a neat concept and is better than the other alternatives I've tried, but doesn't actually do everything I want (plus it's giving in to the Man). - - My computer is not yet as useful to me as a piece of paper, yet it could be so much more! So, I took a deep look at BookMorph (and a shallow look at its rewrites, other presentation software, and the Projects stuff). It seems clunky in places, yes, but there are several really excellent concepts buried in there: - - A page/slide/project. That is, a laid out collection of morphs and behavior that you want to look at/experience together. - - Conscious navigation between pages, including transition effects and sounds. - - Different interfaces for this inter-page navigation: thumbnails, tabs, button controls. - - Navigation on a page: zoom, scroll. - - Templates for pages/slides. That is, a similar layout for several pages, with different data in each. - - Nested pages. I'd like to see one, consistent underlying library that uses these concepts to support presentations, notebooks, tabbed interfaces, HyperCard-like stacks, and projects. I want to be able to easily create presentations and interfaces that work smoothly and that I really like, or at least that nobody has to gripe about. Here's my plan: - - Identify related existing code. - - Identify potential users, opinionated folks :) & collaborators. - - Write up some requirements & design notes, and have whoever cares look them over. - - Refactor, implement or whatever based on the design notes. Existing code I know of so far: - - BookMorph, its subclasses & friends - - SlideshowMorph on SqueakMap (with tests, w00t!) - - Slide Auditor on SqueakMap - - Spiral on SqueakMap - - InternalThreadNavigationMorph & other stuff in MorphicExtras-Navigation - - Projects & World-related stuff If I missed your code, I'm sorry. Please let me know. If you haven't released it yet, I would be very grateful if you were willing to do so, or send me a copy of your working notes/current code/draft. Potential users: - - Folks giving presentations. Based on searches of SqueakMap, conversations about presentation software on squeak-dev, code authors and general scuttlebutt, this includes Stephane Ducasse, Joshua Fein, Bob Arning, Ned Konz, Craig Latta, Lex Spoon, Andreas Raab, and Alan Kay. - - OneNote users. Dunno who this includes beyond me and Ron Teitelbaum but I'm sure there are more of us out there. - - Folks writing tabbed or other page-like interfaces. So far this includes at least me and Cees de Groot. - - Possibly, all Squeak users if the projects & world stuff is really part of this. Looking at the Project stuff might be a second step. What do you think? - - Did I miss anybody in the above categories? Sorry, and please let me know if so. - - Do any other uses leap to your mind? I'll start on the requirements by listing what the existing code seems to be trying to accomplish. If you have requirements beyond this, especially if you are one of the people listed (or who I should have listed) above, please holler. Thanks for listening, if you made it this far, and I'd love to hear your thoughts.

Trying to compile a VM on an x86_64 machine (make/make install, not VMMaker)
by John Thornborrow 03 Jul '08

03 Jul '08

Hello all, I'm trying to build a VM on my Gentoo x86_64 desktop, without much success. The furthest I have got is using the package available on portage (Gentoo's source/package manager) but whenever I try to do anything the VM crashes with a segmentation fault. If I use the self-compiled squeak, squeak does not start - it errors with the "cannot locate vm-display-X11.so" Can anyone advise on just how I can get a VM built and running? Much obliged.

AMB
by Stéphane Rollandin 03 Jul '08

03 Jul '08

from the class comment of AMB, in the attached sar (coming soon to a SqueakMap near you): this is the "ambigous", "nondeterminist", "angelic" operator aka amb ... more seriously described as a declarative control flow statement able to enumerate over finite domains all values that make a program terminate. it uses continuations to walk the tree of possible tuples, backtracking when the program fails. the amazing thing is the simplicity of the code: four short or very short methods on the instance side, the class side methods only providing syntactic sugar. and it can do incredible things such as: AMB assert: [:string :n :char | (string occurrencesOf: char) = n] over: #('maman' 'barbapapa' 'guiliguili' 'arthur' 'chtulu') and: #(2 4 1) and: #($m $b $a $i $u) see AMBTest for more magic. I would have been unable to implement this by myself ! this is a port of the code by Dorai Sitaram which is the reference documentation for amb: http://www.ccs.neu.edu/home/dorai/t-y-scheme/t-y-scheme-Z-H-16.html#node_ch… Stef

I agree with what Ramon Leon has said. I'd also like to continue to see the dev images pre-loaded with stuff most developers would load, but also have a showcase of loadable new packages with some sort of popularity/usefulness/stability indicator if possible or at least a more developed description of what the packages are for. Also a pointer to the best information source and load site would be handy. There are so many packages available in various repositories that it's pretty hard to know what's useful now and an indication of what knowledgeable developers are using would be great. Pre-loading should be a strong indicator that most developers find the package useful. I also agree that you do not want to pre-load too much, don't want to have to take things out in the normal case. It's a fine line for sure. Ken G. Brown >This is the conclusion I also arrived at.

namespaces, version control, package loading and image release compatibility
by Ken G. Brown 03 Jul '08

03 Jul '08

I'm thinking a significant part of the problem of namespaces, version control, package loading and image release compatibility is that many versions of methods and classes can exist in the wild but the names do not include any information about their uniqueness. So when you load something it may stomp on methods that are still required in their previous incarnation for something else to work. Possible solution: - every entity and version of that entity for any image be assigned at creation/modification time a globally unique id that stays with that incarnation of the entity forever. So then whenever a package is loaded with whatever new versions it contains, it does not indiscriminately stomp on previous stuff, and everything else keeps working with the older versions as before, unless it is explicitly desired to move to newer versions. Multiple copies of classes and methods could then exist and be used side by side with the same names in the image since messages are sent to their unique identifiers, not just their name which is incomplete since it contains no version info. Of course tools within the image would be needed to manage the multiple existing unique entities with same names in order to easily upgrade and test previous working packages to using the latest versions, but the tools should allow easily going back and forth between versions along with testing until you are happy that the new works well enough and you could then clean out the old if desired. Wait, isn't Spoon going to do this? Ken G. Brown

Box-Admins Team Report for June, 2008
by Ken Causey 02 Jul '08

02 Jul '08

The box-admins team is reponsible for seeing that the community shared server is maintained and setting up any new features to be hosted on that server. For June, 2008: June was a quiet, lazy summer month. A persistent problem with the FTP daemon failing was worked around by reconfiguring it to be started by Inetd as needed rather than using it as a continuously running independent daemon. I want to thank the community for the monetary support needed to fund the box and remind them that the bills continue to appear and that you can currently contribute to the hosting bills by going to http://www.squeak.org/Foundation/SupportSqueak/ and purchasing a Squeak badge. Note that a donation here may be used for other Squeak Foundation services including but not limited to development, development infrastructure, and promotion of Squeak. The services being hosted have continued to grow and include (but are not limited to): http://www.squeak.org/ SqueakMap - http://map.squeak.org/ http://ftp.squeak.org/ http://lists.squeakfoundation.org/ http://discuss.squeakfoundation.org/ http://source.squeakfoundation.org/ http://map.squeak.org/ https://svn.squeak.org/ http://update.squeakfoundation.org/ http://wiki.squeak.org/ http://bugs.squeak.org/ and DNS services for squeak.org and squeakfoundation.org domain names.

loading one mcz depending on another
by cdrick 02 Jul '08

02 Jul '08

Hi, I need to load 2 mcz. The first need to be initialized before I load the second. I did a Package-all but it doesn't work (syntax error). The load order is ok, but I guess the initialization is done at the end... hence my problem Is it possible to use MCM for that ? I just can't use it.... Thanks Cédrick
