Not quite sure what you mean by formal. Some of the planned and funded testing has been described by Martin and Samuel. We also hope and expect the community here on devel@ and testing@ to do their own testing and report their findings. That's one of the reasons why Daniel and other releasers call for testing publically. Pointing to the test plans in a release would unnecessarily constrain the testing done by the community. Random discovery may exceed the coverage of a test plan. So the absence of a test plan shouldn't be construed as meaning there is no formal testing. The testing done by OLPC, devel@ and testing@ should and does reach the developers. Other distributions will pick up fixes gradually, or if they focus their efforts they can pick up fixes early. It would be easier if Sugar and activities could be tested in a semiautomatic manner. There's no built-in tests in Sugar and activities, but that's an upstream problem that Sugar Labs have occasionally had people look into. > I would like to see whether I can help with this situation, by > recruiting more testers, and setting up something more formal to make > sure that issues don't fall through cracks. Engaging in the existing processes might involve: - giving the smoke test plans to testers, - asking testers to test fixes in a release, by reading the test plans in a ticket, or the ticket problem description, - asking testers to randomly test releases, according to their own expectations, - training testers in the search and report techniques, http://wiki.laptop.org/go/Reporting_bugs#Harder_but_more_helpful:_Trac_with_care On Sun, May 22, 2011 at 09:02:48PM -0400, Samuel Greenfeld wrote: > * The two main organizations within OLPC each have a test/QA engineer > helping them.

To split the load effectively takes one more step ... test PASS reporting. If we know that n other people have done a test without problems, it means we need not concentrate on doing it. So often we only get the test FAIL reporting. So if a volunteer tests something, and it works, that is just as useful for publication as a test failure report.

Re: [Localization] Fwd: Updated 11.2.0 schedule
I was writing a detailed reply, but Martin beat me to the Send button. Just to clarify a few points (which I think you may have been asking): - The two main organizations within OLPC each have a test/QA engineer helping them. James Cameron tends to focus more on the low-level hardware; I tend to focus more on the higher-level software. Beyond that there is a test...@lists.laptop.org mailing list, and a volunteer test group in New Zealand as well as other groups/individuals that casually test and provide feedback as well. When possible, we do try to support upstream test efforts, and file bugs upstream when appropriate. But I do not currently work on testing Sugar for non-related distributions like Ubuntu, although I do have one 10.04 LTS system with Sugar running in it. - If you are looking for a formal test case management system which can be used to store test cases, view things not yet done, and assign tasks, OLPC currently does not have one. Various groups & people have proposed setting up these for OLPC, and some have used them amongst themselves. There is a crude TCMS within OLPC's wiki that can log results and show you that log, but I tend to avoid it due to its habit of caching stale results and personal frustration. One recent idea has been to try Fedora's Nitrate TCMS when that goes online, and ask them to support OLPC builds for test case plans in addition to Fedora versions. But a preview version of that system is not available yet. - We do have a large number of test cases and a crude system within the Wiki, but they mostly have not been updated since 2008. But I have tagged test cases in this system that I feel are still relevant for 11.2.x, and added a few new ones. In addition to these tests I keep a personal spreadsheet of general focus categories (clean start/stop, save/restore, collaboration, etc.) I would like to test with each activity as well as for the base system, and note with which build/activity/platform I last ran that task. It's not perfect, but it saves me writing test cases for 40+ activities that only vary slightly in many ways. - There is a "1 hour" build verification/smoke test for 11.2.0 at http://wiki.laptop.org/go/Smoke_test/11.2.x/1_hour_smoke_test . It is getting somewhat lengthy though since I was asked to include verification of all high-priority activities that kids commonly use. - For 11.2.0, I have gone through every activity on the XO-1 and XO-1.5 and tested basic single-user functionally for all of them that worked at the time. I am hoping that the collaboration stack gets reasonably stable soon so that multi-user functionality can be tested as well. The other main area I would like to check this time around is mime types. Some activities tend to claim they can handle things like audio files, but are not well equipped to handle them if actually given to open, as they were only expecting to embed them into something else, etc. There may also be some activities which should claim functionality that they don't, and some defaults applications for mime types that are undefined. - In general though I agree we need a better way to split the load if other formal test volunteers are available. In addition to 11.2.0, I am often asked to look at the XO-1.75, new potential motherboard or firmware revisions before they are mass produced, or anything interesting thing of the moment (currently "How much of a speedup and/or RAM benefit do we really get by prelinking?"). I would be open to hearing any ideas you may have as well. --- SJG On Sun, May 22, 2011 at 8:32 PM, Martin Langhoff wrote: > On Sun, May 22, 2011 at 1:26 AM, Edward Cherlin > wrote: > > At the end of your e-mail, you wrote > >> Testing is much appreciated. > > It sounds as if there is no formal testing process for Sugar on XOs. > > Hi Ed - For Sugar on XO, we definitely have Sam Greenfeld (QA) and > Gonzalo Odiard (lead Activity developer) doing a very good job of it. > That's why we have the activities in very good shape (try one of our > recent devel builds), and there's also lots of bugs filed, describing > many issues in good detail. > > If you can help with testing, and want to coordinate to avoid > duplicating work and picking interesting areas to focus on - > coordinate with Sam. > > Other distros -- well, are up to other distros. > > > Where is the process from your point of view? > > Until now we've been grabing latest activity from ASLO.

Hi Ed - For Sugar on XO, we definitely have Sam Greenfeld (QA) and Gonzalo Odiard (lead Activity developer) doing a very good job of it. That's why we have the activities in very good shape (try one of our recent devel builds), and there's also lots of bugs filed, describing many issues in good detail. If you can help with testing, and want to coordinate to avoid duplicating work and picking interesting areas to focus on - coordinate with Sam. Other distros -- well, are up to other distros. > Where is the process from your point of view? Until now we've been grabing latest activity from ASLO. Now Daniel has switched to 'freeze' the activity versions. Sam will go through them once more, and bugs in activities will enter our triage selection. The activity maintainers and Gonzalo will work on fixing priority bugs, and a new version of the affected activities will be released which will be hand-picked to be updated in our builds.

re: kids + heirarchical directories
> Preschoolers, I said. Where would you have preliterate preschoolers start? Sorry, didn't catch that part :) Preschoolers are a bit more difficult to teach with this manner :) Sorry, I might be talking about something else, just mostly the concept of [heirarchical files, directories and links], not how the system actually writes to storage + binary data. Well, anyway, here's one way to work with it... Before the "mac/windows" GUI paradigm came along, all of us were working with the command line (and still are). Here's the interesting thing: command lines share a very high similarity with text adventures like the games made by infocom (Zork, etc), so this might be one effective way to get kids to start thinking of the filesystems: Describe directories as virtual rooms where kids can navigate around, and files as the contents of the "rooms". Kids have a natural tendency to explore, and this might be a more natural way to describe the filesystem. You can then describe the filesystem heirarchy as a house or building with different floors and entrances/exits to different rooms. When the filesystem is mapped to a GUI like Gnome/KDE/Mac/Windows, you can then show them how to navigate around the "rooms" (directories) and look at the objects inside the rooms. It will be a little like "Myst" adventure games where you navigate from room to room with buttons, except the kids need to use their imagination more. If you can get kids to visualize this in their minds, it could be a good way to get it to stick. When you get to first to third graders, it becomes a little simpler. Another (horror?) story (sorry about the one with 6 year old streetkids playing violent video games), my neighbor's kid and her friends are on facebook (mostly playing facebook games) and they're thereabouts in that third-grader age demographic. If these kids can navigate websites, then they can navigate filesystems. > What is the reinforcement for third-graders to learn a file system when > XOs provide the Journal? Well, the journal's not a very good place to learn filesystems. The dual boot to Gnome is though. > Who in > the preschool to third grade age group wants to know badly enough, and > why? Preschool would be a bit difficult, but age 7+ will do. When they start creating files, they can be taught how to make folders so that they can organize their files. The journal can get pretty messy when you reach logs in the hundreds. > A single folder is simple. The entire Windows or Linux file system is > insanely complex.

You are to imagine that you are helping > an amazing third-grader understand how the filesystem relates to Sugar > activity development, packaging, QA, and deployment, since it is all so > simple to you. Well, this is a different story altogether. Tinkering with the engine "under the hood" + Sugar dev is a little bit scarier and might be beyond the average third-grader. Even some would adults have difficulty with this. :) For simple stuff like creating notes with a text editors & making drawings with image-editing apps, they should be good with that.

Re: [Localization] Fwd: Updated 11.2.0 schedule
At the end of your e-mail, you wrote > Testing is much appreciated. It sounds as if there is no formal testing process for Sugar on XOs. I know that this is the case for packaging for various distributions. I recently found out through my own testing of the release that Turtle Blocks for Ubuntu Natty was packaged without an essential file, tapalette.py. I assume that it worked for the packager because the file was on his computer from a previous installation or some such. We can't go on like this. We need testing in known and repeatable environments, for one thing, and we need to know who has done what. I would like to see whether I can help with this situation, by recruiting more testers, and setting up something more formal to make sure that issues don't fall through cracks.

Seymour Papert also proposed creating an environment in which learning
math would be as easy as learning ordinary language. Smalltalk has a
number of kinds of number and shape objects, but I have not seen much else
in the way of mathematical objects. I am trying to go through various
subjects to extract the ideas that preschoolers can absorb, and create
materials to encourage them to explore those ideas.
Caleb Gattegno and Ken Iverson did a fair amount on algebra, using
Cuisenaire rods and APL respectively.
Don Cohen has done Calculus by and for Young People
I have made a start on symmetry groups, using variations on children's
block toys.
Elementary set theory using Venn diagrams was done long ago.
But there is so much more.

I would like to be able to create a set of blocks implementing the
symmetry group of a simple shape such as an equilateral triangle. This
case is generated by a 120 degree rotation and a reflection, giving six
elements in all.
Similarly I would like to be able to do modular addition, subtraction,
multiplication, and division in finite fields, and the and and or
functions or union and intersection on lattices.
Does your system accommodate this?

I have an ISO/ANSI standard APL that occupies 29K, thus originally giving a 32K workspace on 8-bit computers with 64K memory. It could easily be expanded to run with any amount of memory. Ken Iverson successfully used IBM APL\360 to teach first-grade arithmetic on a 360 with Selectric terminals.

Here is a complete APL "Hello, World." program, with its output. 'Hello, World.' Hello, World. and a complete Turtle Art version Print<> and then evolving it to be more useful. Precisely. I prefer to teach not only programming but computer science concepts in the early years. One of the great advantages of Turtle Art is that there is no parsing step to translate from linear text with bizarre punctuation rules to a tree structure. The children program directly in effectively preparsed tree structures, with no "syntactic sugar", as the LISPers call it. Also, Walter has built stack primitives into Turtle Blocks, so we can teach stack discipline and the rudiments of FORTH in Turtle Art. He recently added a block to read the color at the turtle's location. I had mentioned to him some time ago that that was the only function missing for me to write a Turing machine in Turtle Art, using colors for cell states and elements in the transition table.

Not the purpose of Turtle Blocks, and not something we would encourage anybody to do. At that point you start writing Python subroutines, and shortly after that you transfer completely to Python. Or Smalltalk. And from there, you can learn the syntactic sugar of any programming language. After learning three different clean p

You were probably thinking of PicoJava, the very first processor for which Sun made the sources available (Microblaze and Picoblaze are 32 and 8 bit processors from Xilinx). I would recommend that anyone interested in this take a look at the Java Oriented Processor: http://www.jopdesign.com/ I keep a list of Smalltalk computers (some with commercial processors, others with language specific CPUs): http://www.merlintec.com:8080/hardware/26 > I'm not terribly interested in those processors. Fair enough, but not only am I extremely interested in them, I also feel they can be a suitable "learning object". I imagine many here are a bit tired of hearing about my SiliconSqueak project, but it is important to point out that it is organized as a sequence of layers: 1) Tiled entry level language: Etoys, Scratch but could also be Turtlescript 2) System language: Smalltalk, but could also be Python or Lua 3) Bytecodes 4) "Microcode", but could also be assembly for ARM or Chuck Thacker's TinyComputer designs 5) Cache level (this is a unique SiliconSqueak thing) 6) logic circuits I think it is reasonable to introduce all children to 1, but for any given level I expect only a tiny fraction to move on to the next level. This is just natural so out of millions of people only two or three might be interested in level 5. Even so, I am willing make as much effort as I can to create a nice learning experience for those three. Level 6 breaks the pattern since it can used for many different interesting projects beyond SiliconSqueak, so many people might be interested in it. I would like to point out the workshops Etienne Delacroix created in Brazil and Uruguay in the past decade as a good example of what can be achieved in this regard. > More in tune with the "turles all the way down" agenda is the work > done on compiling high level languages to hardware.

Nice dream, and I say this as someone who is part of a group of research groups dedicated to making the dream of programming hardware in C come true. The paper doesn't have a data, but from the references I would guess 1996 or 1997. So it doesn't mention System C, Handel-C (killed off, unfortunately) or BlueSpec. Personally, I would select something like Matlab (Octave) as a source language for hardware instead of C. By a strange coincidence, a top researcher in this field was trying to get me intereted on working on the problem of compiling recursive functions to hardware. My own PhD project, "Adaptive Compilation for a Reconfigurable, Parallel, Object-Oriented Architecture", is not entirely unrelated to this. > That said, there is *zero* chance that this work will result in > hardware suitable for the kids we care about.

One problem is that graphical representations are very rich, but not very dense. So factoring stuff better can help a lot (see any code by Chuck Moore). Another solution is to go beyond 2 dimensions - a program is really something that evolves in time and you could make its representation reflect that. I hope to use animation to unify: 1) using the computer with pop up menus and dialog boxes, 2) writing scripts, 3) debugging. Textual representations are really bad at references, unfortunately, beyond a small set of literals, the arguments and some globals. In Etoys I can use any object's halo to ask for a tile representing it and then use this tile in some expression. In Self I could set the value of a local variable by dragging an arrow to point to anything I wanted. My goal is to bring levels 1 and 2 (of my list above) together so the transition won't even be noticed. -- Jecel __

We also need symmetries (group theory and algebra more generally), Venn diagrams (Boolean algebra and set theory), "rubber-sheet" geometry (topology), probability, knot theory (topology), infinities and infinitesimals, graphing (analytic geometry), and conic sections, among other topics easy to visualize and make tactile.

History of math needs to be mined for its moments of adventure, discovery, and controversy. It is widely assumed that math is perfect and unchangeable in its nature. For example, that a theorem once proved stays proved forever. This turns out not to be the case. Lambert thinking he had disproved non-Euclidean geometry, and Peano thinking he had proved that all models of the natural numbers are isomorphic are historically the two most important instances that I know of. Gauss, Lobachevsky, Bolyai, and Riemann realized that Lambert was wrong, and Beltrami finished off the case by demonstrating a surface in Euclidean space with Lobachkevskian geometry.

Sugar includes Python and Smalltalk (Etoys). One Laptop Per Child XO computers also run Open Firmware, written in FORTH, and including the complete FORTH development library, the editor, and an assembler. OFW is available for systems based on ARM processors. The Sugar Labs Replacing Textbooks project, which I started recently, will include a variety of materials for teaching programming and Computer Science, and for applying those languages to every school subject. We have compiled a list of successful projects for teaching programming in the elementary grades, including projects using Python, Smalltalk, Logo, LISP, BASIC, and APL. The real question is one that Seymour Papert asked in 1970: Can we design an environment in which children learn math and programming languages as readily as they learn human languages, largely from each other? Some of us think so, and we are working on it. I will be happy to answer further questions, or to direct you to those who know more about some aspects of Sugar than I. -- Forwarded message -- From: Sean DALY Date: Fri, May 6, 2011 at 11:28 Subject: Re: [Sur] linux system por $25 To: "OLPC para usuarios, docentes, voluntarios y administradores" Cc: Gleducar http://lists.sugarlabs.org/archive/marketing/2011-May/003273.html On Fri, May 6, 2011 at 5:23 PM, Daniel Ajoy wrote: > linux system por $25 > > http://www.raspberrypi.org/ >> >> -- >> Edward Mokurai >> (默雷/धर्ममेघशब्दगर्ज/دھرممیگھشبدگر >> ج) Cherlin >> Silent Thunder is my name, and Children are my nation. >> The Cosmos is my dwelling place, the Truth my destination. >> http://wiki.sugarlabs.org/go/Replacing_Textbooks >> >> ___ >> Devel mailing list >> Devel@lists.laptop.org >> http://lists.laptop.org/listinfo/devel >> > ___ > Devel mailing list > Devel@lists.laptop.org > http://lists.laptop.org/listinfo/devel ___ Devel mailing list Devel@lists.laptop.org http://lists.laptop.org/listinfo/devel
Re: Raspberry Pi $25 computer
It wouldn't be hard to "Port" as there's nothing of Sugar to port. Sugar already runs on ARM platforms without issues getting Fedora running on it shouldn't be too hard. The lack of RAM would likely be a problem, but there are other issues. You need to add a microsd, USB hub and other bits that it would need to be useful. It would be more useful to make it a $30 computer and add more ram and a couple more USB ports but then i suspect the $25 price point was more about marketing than anything else.

os19 filelist checksum fails
Tried a `yum provides */application' on os19/XO-1.5 and I got"http://xs-dev.laptop.org/%7Edsd/repos/f14-xo1.5/repodata/filelists.xml.gz: [Errno -1] Metadata file does not match checksum" I was wondering if this might be related to the fact that I run an os18->os19 (olpc-)updated system or is really something wrong with the specific filelist file.___ Devel mailing list Devel@lists.laptop.org http://lists.laptop.org/listinfo/devel
