Snow only delayed the restart -- Squeak Swiki is now available again.

The colors indicate successive stages: finding the latest version, retrieving it, decompressing it and installing it. As it runs, it tries (not very well at the moment) to predict how long it's going to take and make it the progress wipe finish at the same time as the load (or publish). If it takes longer than the estimate, then the wipe repeats, this time a little darker. Cheers, Bob

Hi Karl, On Tue, 19 Dec 2000 16:44:27 +0100 Karl Ramberg <karl.ramberg(a)chello.se> wrote: >I played around a little with Bobs SuperSwiki and it's amacing:-) >This stuff is really cool, could you tell us a little more ? It's an experiment in providing a bit of server support for project publishing. It is a swiki that can be accessed at http://209.143.91.36/super and it supports a protocol for publishing and retrieving projects. Publishing a project using the 'Publish' button on the navigator strip also updates a swiki page (several in fact) that provide an overview when seen from a browser. Publishing a project can also store information such as author, description, etc (although this is a bit difficult to access at the moment). To search for a project, press the 'Find' button on the navigator strip and hold until the menu appears. Then select 'search the SuperSwiki'. You will get a purple window with spaces to fill in search criteria. Once you fill this in and hit OK, you will get a morph containing thumbnails of projects that matched. Clicking on one of these should load the project. (There is a bug in this morph related to recent alignment morph changes that I will fix today, but it shouldn't hinder its use). The stuff that's out there is a jumble of various tests and may not all be usable in the current image. Some are essentially content-free, while others have various bits of flotsam and jetsam. Some things are categorized to aid in testing, but the categorizations are largely random (i.e. don't expect intelligent search results on what's there). As an experiment, all are welcome to publish stuff here with the following understandings: - nothing of a copyrighted/illegal nature is welcome - it is an experiment and may be changed/discontinued without warning - it is a notebook computer on a DSL line, so it won't be the fastest server you have ever seen - very large uploads may fail - etc, etc. >And one buggish note, the project browser, (the on that pops up >after pressing find on the project navigator morph) looks not >so good in 8 bit screen depth. It's the gradients used. Any way you can get up to 16-bits? :-) Cheers, Bob

Hi I played around a little with Bobs SuperSwiki and it's amacing:-) This stuff is really cool, could you tell us a little more ? And one buggish note, the project browser, (the on that pops up after pressing find on the project navigator morph) looks not so good in 8 bit screen depth. Karl

Squeak on iPaq..success!
by Kevin Fisher 19 Dec '00

19 Dec '00

Well after several re-flashings of the iPaq's flash with successively smaller images, I've finally gotten Squeak 2.9a up and running on the iPaq. I used "Smalltalk majorShrink; abandonSources" and got the image down to 1.7 megs with a tiny changes file...more than enough! So, as soon as I can break my ancient Xap Shot out of mothballs I'll try to snap a few pictures. MVC looks really sharp on the iPaq LCD, I must say. :) One nice thing about the Xserver on the iPaq is that it operates in both portrait and landscape mode...the Browser is quite readable and usable in landscape mode. A couple notes: The majorShrink seems to have had some unpleasant side-effects. When I save the shrunken image I get an error box complaining about a missing seperator. Still, it saves the image. As I briefly mentioned, using "Smalltalk lastRemove" seems to hang the VM. If you cmd-. you can break out of it..it seems to be hung in a Semaphore. Ok...well, next step: Morphic!

Check out WorldState>>drawWorld:submorphs:invalidAreasOn: (it used >to be PasteUpMorph>>drawInvalidAreasOn: but Bob shuffles methods around >faster than you can look ;^) Bert & Henrik, I would say that it is a combination. The strategy starts top-down to determine which morph(s) will be necessary to correctly draw a particular rectangle on the screen. Once those morphs are determined, that rectangle is drawn using those morphs from the bottom up, to insure that translucent areas have the correct background. As Bert pointed out, morphs which do not accurately answer #areasRemainingToFill: can lead to drawing errors or unnecessary extra drawing. Cheers, Bob

Snow Socks Servers
by Mark Guzdial 19 Dec '00

19 Dec '00

Of course, the night that our servers are down and packed, Atlanta gets hit with a freak snow "storm." (We got 1-3 inches, which doesn't qualify as a "storm" in Michigan where I'm from, but it shuts the city down in Atlanta.) So, it's not clear when (if) the servers (like Minnow) will be moved, unpacked, and restarted today. I apologize for the delay, and will let you know when the Squeak Swiki has returned to service.

Advice on squeaklets needed
by Russell Allen 19 Dec '00

19 Dec '00

Hi all, This is a question for all the people who've been playing with squeaklets. I have a squeak application that I want to turn into a squeaklet. The app consists of: * 156K source code (uncompressed) * 272K data file (a gzipped lexicon) * 30K images (gzipped bmps) Grand total: 458K Now, my question is what is the best way to deliver this so as to keep the download size and the compilation time smallest? I don't know much about how to use the image segment stuff - is it possible to deliver the source code compiled, rather than downloading then fileing it in? My current thinking was that the squeaklet would load and compile a short script which would download the other components, unzip and compile them, then start the application. Does anyone know any better way? Thanks for any help...
