Squeak 4.5 Released!

21 March, 2014


From Chris Muller:

So!  Let it be known!  Squeak 4.5 is released!

Home page is here:  http://www.squeak.org

4.5 release notes are here:  http://wiki.squeak.org/squeak/6193

Excellent Job Everyone!!  Can you tell we are excited!


Check out OLPC XO-4.

I would hate to add to the speculation that OLPC is dead because it’s not.  Wayan Wota has been calling OLPC dead for 5 years. This is not news. He has not been involved with the project in a long time. His article is about the XO-1, apparently he doesn’t even know the XO-4 was officially introduced at this year’s CES, alongside the tablet.

If you really want to know what’s going on with current OLPC community projects see Adam Holt’s http://www.unleashkids.org/

Full OLPC Statement (from: http://gizmodo.com/one-laptop-per-child-isnt-quite-dead-yet-1541430670):

OLPC’s mission to empower the world’s children through education is far from over. OLPC is thriving and making more inroads at bringing education to those who can’t easily access it. OLPC recently formed a strategic alliance with the Zamora Teran family through many of their enterprises and their philanthropic foundation, the “Fundación Zamora Teran to deliver XO laptops not only to Central and South America, but also to Africa.

Aside from distributing more laptops in several schools in Costa Rica, Uruguay is receiving its first 50k units of the XO-4 Touch (running Android) in a few weeks’ time. In addition, the XO Tablet is currently available directly through governments and NGOs, as well as in Europe and Canada and through all major retail outlets in the United States including Walmart, Amazon, Toys ‘R Us among the others.

OLPC also has outsourced many of the software and development units because the organization is becoming more hardware and OS agnostic, concentrating on its core values – education. As an example, we’ve partnered with the Smithsonian Museum to bring feature-rich, interactive and more targeted content to our young learners.

We have more exciting things planned in the horizon including the implementation of very large scale projects in several regions of the world, so be sure to stay tuned.

OLPC is a concept, it is a movement, it is a community and it is about helping children.  Sure the grand vision may be delayed, but the benefits of education and technology, of improving the human condition is not dead.  We all knew that it’s not profitable to teach third world children.  Still,  no one thought that companies would compete against OLPC.  Countries opted for different technologies for hardware but never matched the promise or the vision of the software.  Had the world united around this platform children would have benefited and the world today would be a better place as we develop together and stamp out ignorance.  There is nothing like education to improve the world and that mission is not dead.  OLPC is evolving, finding new ways to reach more children, making more with less, and finding ways to make a real difference in the world.

Support OLPC!  Long Live the vision.


From Clément’s post to the pharo community:

Hello pharoers,

The new Cog memory manager, Spur, is simply *amazing*. I saw at FOSDEM that some of you were interested in it, but unfortunately you were lacking information about it.

I wrote a one page article that sums up Spur’s new features so every one can know what will be better. There’s no VM technical details here, it’s just about what will change for a regular pharo user.


Let me know if you think I forgot yet another feature.

If you have questions, I’ll try to answer, but ask Eliot, he implemented Spur so he can answer your questions much better than I can :-).




From: Chris Muller:

It’s ready for your final testing and scrutiny!


Please bang on this!  Test it with your apps.  Test it in Windows, iOS, Linux.  Interpreter and Cog.

Unless we hit any show-stoppers, this will be the one we can call “done.”

Thanks to this great community of brilliant developers for making 4.5 a superb release.

Squeak needs you!

23 January, 2014



It’s time to encourage our best community members to step up and serve.  Put your name in the race and get elected to the Squeak Oversight Board.  Talk to people – you know who they are – that really should run.

From Tim:

Being on the board is not an onerous job. It does not require exotic technical skills. What it does need is an interest in caring for how the Squeak world keeps going, some time to take part in discussions and occasional debates about what ought to be done with the organisation, and a large cellar of excellent vintages to share when the expansive travel budget provides for a meeting to be held in your chateau. Some of the aforementioned might be exaggeration.

Many of the regulars at posting here [squeak-dev] could be excellent board-members. Please, take a moment to consider running.



Clément Béra just posted an excellent article explaining the new Spur Object format.  Definitely worth a read!

Eliot Miranda has also mentioned that Spur is coming to life in Newspeak as we speak and then Squeak 5.0.

Find out more about the Squeak VM called Cog and the new memory manager called Spur at Eliot’s Cog Blog.
