[Sugar-devel] Computation for thinking with (was IAEP] Sugar Digest 2013-10-05)

Ken Iverson's Turing Award lecture was titled Notation as a Tool of Thought. http://www.jsoftware.com/papers/tot.htm He, of course, used examples from his own language, APL (A Programming Language), which inspired the creation of Backus's functional programming languages (described in his Turing Award lecture), and many others. He quoted Concerning language, George Boole in his Laws of Thought [1, p.24] asserted “That language is an instrument of human reason, and not merely a medium for the expression of thought, is a truth generally admitted.” Mathematical notation provides perhaps the best-known and best-developed example of language used consciously as a tool of thought. Recognition of the important role of notation in mathematics is clear from the quotations from mathematicians given in Cajori’s A History of Mathematical Notations [2, pp.332,331]. They are well worth reading in full, but the following excerpts suggest the tone: By relieving the brain of all unnecessary work, a good notation sets it free to concentrate on more advanced problems, and in effect increases the mental power of the race. A.N. Whitehead Ken's son Eric organized the annual Tool of Thought Conference to follow up on that idea. You can see an example applied to our work with Sugar, in Iverson's algebra textbook, which I have updated at http://booki.treehouse.su/algebra-an-algorithmic-treatment/ as part of the Sugar Labs program for Replacing Textbooks (with Open Educational Resources). Of course it would help if we could get the language concerned, J, packaged for Fedora and Sugar. In mathematics, the otherwise contentious Sapir-Whorf Hypothesis, that the structure of language sets limits on what is readily thought, is simply understood as a given. Of course, it does not mean that we cannot go beyond those limits, just that it is very, very hard, and that in some cases we have to invent more language so that more people can do it. Historically, the clearest example is the difference between the Newton dot and Leibniz d notations for calculus. Due to the nationalist furore over precedence between Britain and Germany, British mathematicians refused to use the Leibniz d notation until Charles Babbage founded the Analytical Society to "replace the dot-age of England with the d-ism of the Continent". Thus the proliferation of mathematical notations and of programming languages and paradigms ever since. There is a good deal more to this story, including the fact that Turtle Art tree-structured programming is superior in Computer Science terms and for children's use to textual programming, but I will leave that unless somebody asks me. -- Edward Mokurai (默雷/निशब्दगर्ज/نشبدگرج) Cherlin Silent Thunder is my name, and Children are my nation.

Re: [Sugar-devel] Usage of sugar-build
Alt-tab to go between Sugar and other programs is very clumsy at first, but works. When I do this from a full-screen Sugar session I don't get the usual view of icons of other applications to choose from, but once I have Sugar and the program I want to alternate with set up for toggling between, it is quite easy.

I see that the SoaS pages on the Sugar Labs Wiki are seriously out of date, referring to Version 7 http://wiki.sugarlabs.org/go/Soas Version 4 http://wiki.sugarlabs.org/go/Sugar_on_a_Stick_QA Release 1 http://wiki.sugarlabs.org/go/Running_Linux_Applications_Under_Sugar No version number given, but dated 2010 http://wiki.sugarlabs.org/go/Activity_Team/Testing V5 for MacBook, Version 7 http://wiki.sugarlabs.org/go/Downloads The Fedora Spins page doesn't say what version of SoaS it is offering at all. http://spins.fedoraproject.org/soas/ Also, the Wiki fails to document release 0.98. It is out, according to http://wiki.sugarlabs.org/go/0.98/Roadmap But it is not listed for any platform at http://wiki.sugarlabs.org/go/Downloads#Do_you_use_GNU.2FLinux.3F Separately from that, the Sweets repository for Ubuntu doesn't seem to exist. http://wiki.sugarlabs.org/go/Sweets_Distribution/Manual_Installation Nor does the Ubuntu Sugar Team page. I would take that up with the Ubuntu Sugar Team if I could find it. ^_^ Sugar on Ubuntu is severely broken. Most activities fail to start. None of it should have been released in that state. http://wiki.sugarlabs.org/go/Development_Team/Packaging lists this page https://wiki.ubuntu.com/SugarTeam which the Wiki says does not and has never existed. >>> > I would like to see more people testing and using it during the dev >>> > cycle so I don't get the "My Activity is broken" post release or five >>> > minutes before release when we're generating final images and pushing >>> > them out to the Fedora mirrors.

Can we get a Wiki page listing them, or an external link, and can we talk about testing SoaS on them _all_? If I could get funded to buy one of each and set up a modest test station with proper storage, power, and work area and all relevant ARM SoaS versions actually on sticks, I might volunteer to do that in between writing OERs and recruiting others to do so. > Peter -- Edward Mokurai (默雷/निशब्दगर्ज/نشبدگرج) Cherlin Silent Thunder is my name, and Children are my nation.

Re: [Sugar-devel] [IAEP] video of XOs in the Amazon
I added a paragraph on the documentary and the YouTube excerpt, with references, to the English-language version of the page. Can somebody let the children know so that they can translate it for the Spanish-language page? http://en.wikipedia.org/wiki/Palestina,_Peru I have wanted to suggest this practice of having students write Wikipedia pages as a regular part of the curriculum for every OLPC deployment, starting with pages in the local languages on every local subject, and expanding to translations by students of various other languages as they become sufficiently capable. I will write this up for my blog, http://replacingtextbooks.wordpress.com/ This page mentions caywa, evidently a local crop for which there is no Wikipedia page in either Spanish or English. I do not find it in Spanish Wiktionary, either. Here is another page that mentions caywa without explanation. http://sachamama.livingroutes.org/2011/07/28/shukshuyaku/ Apparently the standard spelling is caigua, and the name is derived from Quechua kaywa. http://www.yanuq.com/buscador.asp?idreceta=1095 http://es.wiktionary.org/wiki/caigua So I added a link to Cyclanthera pedata «Caigua» redirige aquí Please thank the students for me, and let them know that I was delighted to have the opportunity for a collaboration with them.

Let me add a question, then, where I would like to get some feedback. One of the ideas at the foundation of the Sugar Labs program for Replacing Textbooks (with OERs) is to be able to write learning materials using tools such as HTML5 or EPUB3 in a way that would allow us to embed and script Sugar activities. This would make it straightforward to implement a curriculum fully integrated with Sugar. (We could also discuss what other Sugar activities would be needed for the purpose, and whether existing Sugar activities would need to be adapted to make all of this work.) Do we know how to do such a thing in HTML5? What other questions do we need to ask in order to start looking for more answers? >>* I think we have a bit of a different perspective.

Re: [Sugar-devel] [IAEP] Factorisation visualisation was Sugar Digest 2013-01-25
You can't do functions with arguments in Turtle Art, and so obviously you can't do full recursion with stacked and shadowed arguments directly in Turtle Art, but you can implement much of recursion in any of the usual ways using the push and pop stack blocks or other dodges. Have a look at the fractal examples in the library. Or you could call Python to create a list to store partial results in. The case of tail recursion, where none of the recursive calls have to return because the recursive call is the last statement in the function, is easy. In pseudocode, with handwaving of some details that I leave as exercises, Set count to 0 Give variable n a positive integer value. Factorize If n=1, end ElseIf n is prime, push n; increment count Else find a factor m of n, and push that factor; increment count Factorize n/m ShowResult while count>0 print pop m decrement count Of course in Logo you have full recursion. In the Etoys version of Turtle Art, you can use recursion in Smalltalk.

[Sugar-devel] Students developing programs

What age, and how much programming experience do they have, in which languages? MYOSA is good for Python. You should also consider Etoys and Squeak. I am working on the Etoys Reference Manual http://en.flossmanuals.net/etoys-reference-manual/ and will start on a Discovery manual after that, explaining how one can learn Etoys even without adequate documentation, which is what I am currently doing myself. I do not think that I could attempt to write manuals on any other language while learning it. There are a number of elementary tutorials provided with Etoys, and some further ones at Waveplace that you can find through Squeakland.org. Then there is a large gap that I am beginning to see how to fill, in part by breaking out of Etoys to access the behind-the-covers Squeak IDE. I can recommend Squeak by Example up to a point. It does not have enough examples, for starters. It explains the language and IDE to some extent, but not how to read existing Smalltalk object definitions and how to determine which existing objects would be useful as starting points for new development. Looking at existing projects will help with that. We will be discussing these issues on the Squeak Development list. For those just learning programming, I recommend one or another form of Turtle Art. Walter's version, written in Python, is good in itself and also for providing an interface to put Python code on Turtle blocks, so that learners can get into Python incrementally, and go as far and as fast as they like. Etoys can be used as a glorified Turtle Art, starting with similar movement and pen commends. One can in principle add Smalltalk methods to Etoys programming tiles via Squeak (which is how Etoys was created in the first place), although I have not seen the details. Tony Forster and I have written a number of Turtle Art tutorials on Turtle Art itself and on its use for a wide range of math topics. I have documented how to use the built-in translation to Logo, and I mean to translate some of them to Etoys. http://wiki.sugarlabs.org/go/Activities/TurtleArt/Tutorials > Thanks. > Gerald -- Edward Mokurai (默雷/निशब्दगर्ज/نشبدگرج) Cherlin Silent Thunder is my name, and Children are my nation.

I would go further. Can we invite the children to give us their stories? They should be wikified, blogged, made the subject of articles in the geek and education press, and spread even more widely than that. Better still, can we invite the schools where this children are learning and sharing to celebrate them using Sugar tools to create interactive presentations?

[Sugar-devel] Sugar Activity template for HTML5/Enyo
Excellent. I have been wanting a way to use HTML5 with various Sugar activities in the Replacing Textbooks program, both to write interactive tutorials on the activities, and to write subject-matter materials incorporating Sugar. Can you see how to do this? Can we adapt existing activities in Python and other languages to work with your template? What would it take to link to Etoys and Scratch, as the next language extension?

[Sugar-devel] New activities
I am a member of two communities that have some interest in getting their Free Software into Sugar. One is the J programming language, a version of APL. The reason for bringing it into Sugar is that IBM ran a project in the 1970s to allow later Turing Award winner Ken Iverson to use it to teach arithmetic starting in first grade. The second is the Open Voting Consortium's voting software for an auditable electronic ballot printing system, as opposed to the unauditable, insecure, easily-hacked DREs (Direct Recording Electronic voting machines) in widespread use after the 2000 hanging chad debacle. Our software people need a bit of assistance with the Sugar way of doing things, and with packaging for Sugar(.xo) and for Linux (apt or yum). Anybody who is interested can contact me offline. I am also talking with people in the digital publications world about new Free Software coming out. I will have more such packages to ask about sometime in the near future. -- Edward Mokurai (默雷/निशब्दगर्ज/نشبدگرج) Cherlin Silent Thunder is my name, and Children are my nation.

The big picture answer, apart from instructions for non-standard installations from non-standard repositories, is to work with the Debian and Ubuntu packagers to streamline the packaging of new Sugar releases in order to get them into the upgrade stream in a timely manner. If somebody involved in the process can explain exactly what is needed, I expect that we can recruit some more helpers. (Similarly for RPM packaging for Red Hat and other distributions that use that format.) My understanding is that the process can be automated in whole or in part if the dependencies don't change radically between versions. Someone like Jonas Smedegaard who is involved in the process can correct me if I have misunderstood, and can greatly amplify what I am telling you. > What to do with > the fancy link > http://download.sugarlabs.org/packages/SweetsDistribution:/0.94/Ubuntu-11.04/ > > I happened to know what is /etc/apt/sources.list . > http://manpages.ubuntu.com/manpages/natty/man5/sources.list.5.html > > You should know what I mean, BUT: > Should we have some documentation for adding this repository in CLI and > GUI? > Should we have a PPA to make things easier?

It would be excellent to bring it together on the Sugarlabs Wiki, and it would be excellent to have somebody learn it in detail and offer to create keyboards for all languages used in OLPC deployments. I can show you the list of supported layouts, and we could make a list of keyboard layouts needed. Then we would have to consult with users of the languages about what needs to be on those layouts, and whether there are any preferences based on, for example, existing typewriter layouts. Sugar uses standard X keyboards, the same as in Gnome, KDE, and all other graphical Unix/Linux environments. The keyboard files are in ASCII, with extended characters specified by name or by Unicode number. Here are a starting point. The command to change keyboards in Linux is setxkbmap. man setxkbmap The setxkbmap command maps the keyboard to use the layout determined by the options specified on the command line. An XKB keymap is constructed from a number of components which are com‐ piled only as needed. The source for all of the components can be found in /usr/share/X11/xkb. in the symbols subdirectory. Articles on creating your own keyboard layout text files have been published in several magazines, and are available on the Internet. If you want to pursue this after you take a look at the file format, I will dig out some references for you. > Thanks, > Sridhar > > > Sridhar Dhanapalan > Engineering Manager > One Laptop per Child Australia > M: +61 425 239 701 > E: srid...@laptop.org.au > A: G.P.O.

[Sugar-devel] Unity desktop in Ubuntu (was Re: Is Apple's New OS X Copying Sugar???)

So is Ubuntu's new default desktop, Unity. Instead of a menu of applications, it has a display of icons for frequently-used apps, installed apps, and installable apps, with an option to select a subset such as Office, Accessories, System and so on, and a search box for typing any part of the app name or description. But these ideas are in the air. The search field in our journal or in Unity is very much like the Firefox Awesome Bar for searching by URL or title among Web pages that you have visited. Unity also has a bar on the left for active apps and some other icons, which relates to the Apple dock and also to the Sugar frame. Like the frame, it slides out when you put the mouse pointer into the corner or along the edge, according to a preference setting. One of the icons allows you to search for a document by icon or with the search box, rather like the Journal except that it also searches for folders. > The most striking is the new "Air Drop" feature which is, essentially, our > mesh network!

[Sugar-devel] Upstreaming (was Re: [ASLO] Release Turtle Blocks-108)
Yay, Turtle Art 108 installs and runs on Ubuntu Natty! 107 didn't. This will make it much easier for me to work on my preschool math project in Replacing Textbooks. I expanded the Upstreaming bugs Wiki page from just Fedora to cover ten distros, including links to the various bug trackers and bug howtos, and listed all of the Ubuntu activity bugs. I will be delighted to be able to recommend packaging TA 108 for Ubuntu (Bug #731133). I can't possibly keep up with all of these distros, so if anybody else wants to take one, please add a section to the page.

If the server can be made to appear in the frame in much the same way that an inserted USB drive appears, this task will be easy. Or I should say, a shared folder on the server, perhaps one per class or one per child.
