Assunto: [Geral] Squeak-Etoys 4.0 completamente livre
Gente!
Agora na recém-lançada versão 4, o Squeak-Etoys é completamente livre. Vejam
abaixo. Eles reescreveram e limparam o código fonte.
Baixe em: http://squeakland.org/download (inclusive uma versão portátil para
pen drive)
License Clean
Etoys 4 is now "license clean", which means it conforms to the requirements of
free and open source systems, such as the various Linux distributions. In 1996,
Apple released Squeak under their own license. In 2006, Apple relicensed the
Squeak core under the Apache 2.0 license, thanks to Steve Jobs, Alan Kay, and
the lawyers involved. Soon after, Viewpoints Research collected written
relicensing agreements from several hundred contributors under the MIT license,
thanks to Kim Rose and the Squeak community volunteers. Finally, all code in
Etoys not explicitly covered by a relicensing agreement was removed, rewritten,
or reverted to an earlier version, thanks primarily to the efforts of Yoshiki
Ohshima. The result of this hard work is that Squeak Etoys is now completely
free and open source, which means it can be used and modified by anyone in the
world for whatever purpose they imagine.

Fall 2009 Etoys 4 and the new Showcase
Great Hope for the Future
Squeak Etoys 4 Release Notes
Etoys 4 and the new Showcase
by Timothy Falconer Squeakland is proud to announce the release of Etoys 4,
which you can now download from our website. Special thanks to the Squeakland
software team, particularly Bert Freudenberg, Yoshiki Ohshima, and Scott
Wallace for their tremendous efforts in the last month. Your hard work really
shows!
Below you'll find some thoughts by Scott Wallace, along with the Etoys 4
release notes which detail the changes you'll find. Of special interest is the
new Squeakland Showcase. Everyone can now share their projects directly from
Etoys to our website, where the Etoys community can then benefit from the many
surprising and useful Etoys examples that are available. Please explore the
showcase and share your projects with us. We want to hear from you!
Also, if you haven't signed our Squeakers list, consider adding your name. As
I write this, more than 175 people from 35 countries have signed, which really
shows the enthusiasm and reach of Etoys throughout the world.
Great Hope for the Future
by Scott Wallace The Etoys 4 release completes the hand-over of Squeak Etoys
from Viewpoints Research to the newly formed Squeakland Foundation. Under the
leadership of Timothy Falconer and Rita Freudenberg, Squeakland Foundation has
now assumed full responsibility for everything Etoys, including the Squeakland
website, the mailing lists, the bug-tracking system, Squeakfests,
documentation, community development, and now the Etoys software itself.
Throughout the 2009 transition, Viewpointers were involved on an almost daily
basis with the software team. Etoys 4 marks the end of that formal
involvement. Many of us will continue as ordinary, contributing members of the
Squeak Etoys community on a volunteer basis, but the system and the vision and
the future of Etoys are now entirely in the hands of Squeakland Foundation, and
thus, more than ever, in the hands of the broader community itself.
For those of us who have been involved with Etoys for many years, it is a
poignant moment. Since the beginning, a small core group of us at Viewpoints
Research have always had ultimate responsibility for Squeak Etoys -- the code,
the decisions, the releases. Passing those powers and responsibilities on will
not be entirely painless for us, but it's a goal of Viewpoints to spin out
research prototypes beyond our lab. It's also the right thing to do, given the
recent increase in Etoys usage due to OLPC.
Several things give me great hope that the future of Etoys is bright. Foremost
is the promise of the new website, particularly the Showcase, with its
"featured" projects vetted by the education team and with the ability for
children and adults to save and share their projects on the site. The content
and evolution of the Showcase will comprise a centerpiece and gathering place
for our community. We will all benefit and learn from the sharing of
interesting projects. Secondly, people in the community have started posting
code fixes and enhancements to our software tracker, and the new etoys-dev
mailing list has been active. And lastly, witnessing the commitment and
strength of people in the community, beginning with Tim and Rita, and
continuing through our strong teams of educators, business people, and software
writers, and ultimately with the passion of our hardy, worldwide community of
users. All of these things give me confidence and optimism
that Etoys will continue to thrive and inspire for many years to come.
Squeak Etoys 4 Release Notes Etoys 4 has three major new changes and many
smaller improvements. Representing a year's worth of work, Etoys 4 is the last
release to include the direct participation Viewpoints Research, as their focus
has always been to create prototypes and spin them out into new organizations.
Viewpoints will now pass the reigns over to the newly formed Squeakland
Foundation, whose mission is to "build community and encourage deep learning
worldwide by promoting, supporting, and improving Squeak Etoys and related
educational media."
Please join us!
ShowcaseThe biggest change to Etoys and the Squeakland website is our new
project showcase. You may now share projects directly from Etoys to the
Squeakland website. Simply click the Save button, give project details, and
choose "My Squeakland" as the save location. To get a showcase account, visit
http://squeakland.org/action/signup.
You can then access your project from the Squeakland website or directly within
Etoys itself, using the Load button. This allows you to use the website as a
central place to store your Etoys projects, whether you wish to make them
public or not. When you first upload a project, it's marked private, which
means only you or your friends may see it. (Friends functionality will be
added later this year.) You can then choose to make your project public by
clicking "make public" on the project page. After being reviewed by other
users for inappropriate content, your project will then become visible to
everyone. Please help us show off the best Etoys projects!
Etoys-To-GoThe next big change is called "Etoys-To-Go", which is a new way to
install and use Etoys. Simply choose Etoys-To-Go from the download page
instead of Windows, Mac, or Linux. You'll then have a portable Etoys that
works on any computer that can be easily copied from machine to machine,
without the added installation step. Even better, you can run Etoys-To-go
directly from a USB flash drive, which means you can use Etoys on any computer
without getting permission from system administrators. Your project files are
saved back to the USB stick, so you can quickly save and run on your way to
school. Unfortunately, Etoys-To-Go does not include our browser plugin, so if
you want to browse projects on the web, you'll still need to download and
install the usual Windows, Mac, or Linux version. Project files can be easily
exchanged between the Etoys-To-Go, Mac, Windows, and Linux versions.
License CleanEtoys 4 is now "license clean", which means it conforms to the
requirements of free and open source systems, such as the various Linux
distributions. In 1996, Apple released Squeak under their own license. In
2006, Apple relicensed the Squeak core under the Apache 2.0 license, thanks to
Steve Jobs, Alan Kay, and the lawyers involved. Soon after, Viewpoints Research
collected written relicensing agreements from several hundred contributors
under the MIT license, thanks to Kim Rose and the Squeak community volunteers.
Finally, all code in Etoys not explicitly covered by a relicensing agreement
was removed, rewritten, or reverted to an earlier version, thanks primarily to
the efforts of Yoshiki Ohshima. The result of this hard work is that Squeak
Etoys is now completely free and open source, which means it can be used and
modified by anyone in the world for whatever purpose they imagine.
Improvements
* The project-info box fields were updated to match the new Squeakland
showcase.
* The load box lets you browse not only local files, but projects in
the Squeakland showcase as well.
* The local document directory is automatically pre-selected when
saving a project.
* Projects are now created at a 1200x900 pixel resolution by default,
and scaled to the actual Etoys window size. This ensures easier sharing of
projects between computers of different screen resolution.
* The former display-mode button in the toolbar now toggles full-screen
mode. To access the scaling options menu, hold down the button.
* On the right of the toolbar, there is a new button that governs
toolbar visibility.
* To minimize the chance of obscuring essential content when opening
older projects, the toolbar will now appear in its collapsed form, at the
top-right corner of the screen.
* New icons were chosen for Quit, Load, and Save buttons. Under Sugar,
the Stop, Import, and Keep icons are used instead.
* The "undo" button was removed to make room in the toolbar, as it did
not work reliably anyway.
* We renamed the startup screen to "Home".
* The home screen is now always accessible via project navigation
buttons.
* We now show the full set of choices in the authoring-tools menu to
all users whether eToyFriendly is turned on or not.
* A book's navigation bar is now protected from being ripped out
accidentally.
* Objects can now be copied into and out of Etoys using the system
clipboard. When the halo is visible, press Ctrl-C to copy (Cmd-C on Mac).
* The world now receives all keystrokes for better scripting of
keyboard-controlled projects.
* The less widely-used items of the "geometry" category have been moved
out to a new category called "more geometry".
* Opening a new category pane now closes other categories if there
isn't enough vertical space on the screen.
* The "bearing to" and "distance to" tiles now respect an object's
reference position (center of rotation).
* The grab-patch tool can now be dragged in any direction, not just
top-left to bottom-right.
* Lasso and grab-patch tools were moved back to Supplies flap.
* Wording improvements were made in several menus and help balloons.
* On Linux, sound compatibility has been improved.
* The separate .gif file is no longer generated.
* Saving a project now includes a "thumbnail.png" inside the project.
You can use a zip tool to extract the thumbnail if needed.
* The Mac Finder now shows a thumbnail for new project files.
* Translations and Quick Quides now work in the web browser plugin.
* Etoys now ships the ScratchPlugin (although we only use the "open URL
in web browser" primitive so far). Thanks to Mitchel Resnick and John Maloney
and the other Lifelong Kindergardeners.
Known Bugs
* Uploading a project from Etoys to Squeakland does not work if you are
behind a proxy. Please use a web browser to upload projects in this case.
* On Snow Leopard, the web browser plugin works unreliable in Safari.
We recommend using Firefox until we fix this problem.
* If you encounter issues in the plugin, try clicking the full-screen
button in the toolbar. This can fix animation sluggishness, repainting
problems, and wrong key/button mappings.
