XOCamp 2

The XOcamp 2 miniconference in Has location city::Cambridge Has location country::USA, is scheduled for January 12, 2008 to January 16, 2008

FUDcon will be Jan 9-11 See: http://fedoraproject.org/wiki/FUDCon/FUDConF11. XOCamp will be the week following, Jan 12-14 and it will have tracks for technical and community events. Thursday and Friday that week (Jan 15 and 16) will be reserved for other meetings and wrap-up sessions for the organizers.

The purpose of the XOCamp is to help frame our long-term software development effort. In addition, we will work on prioritizing requirements, features and goals for the next major feature release called XO Software Release 9.1.0 and the Sugar 0.84 release. It will probably be similar to XOcamp 1 in nature.

• Bryan Berry and Tony Anderson will lead the discussion
• Powerpoint presentation will accompany the talk

Software Engineering - 4 hours

Distributing OLPC

Summary: Open discussion to address the following questions.

1. How can OLPC encourage worldwide decentralized community development models for pedagogy and the content and software to support it?
   1. And then let the whole worldwide community benefit? _{Yamaplos 19:39, 13 November 2008 (UTC)}
2. How can communication between/among OLPC-the-organization and grassroots pedagogical, content, and software developers be improved?
   1. Define, clarify channels. Who do you contact for a small deployment? How do you distribute not just green bricks but knowledge and training? Who should you contact in 1CC for what kind of issue? _{Yamaplos 19:39, 13 November 2008 (UTC)}
3. Whether and how we want the volunteer community to help us with 9.1
   1. If OLPC-the-organizations says that we support the open-source mentality and that we encourage volunteers, we should articulate exactly what kind of volunteer support we want and need, the kind of relationship the organization would like to have with the community, and the kind of support (including support and resources that are conditional) we can provide them with. Mchua 16:54, 29 October 2008 (UTC)
   2. I personally think that it is especially important to articulate the kind of volunteer projects we won't support and do not have resources for, so that community members know what they have to do completely independently of OLPC. Knowing the answer is a no is better, for planning and getting-things-done purposes, than remaining in a nebulous "maybe?" state. Mchua 16:54, 29 October 2008 (UTC)

• How much time is needed - 1 hour
• Who can lead the discussion - Rafael, (Mel available for backup)
• What preparation and materials should be created (e.g. presentations, code samples, other)?

Status - On track to include. Next steps, ToC for presentation.

Why is this under "software engineering"? No doubt there are software-related issues we need to address, but this is primarily a wetware issue. The tools are there, agreed they are not perfect, yet the fact they are not being used has to do with how we reach (or miss reaching) people, not with hardware or software. Yamaplos 17:57, 2 December 2008 (UTC)

Forgotten or Missing Tools

Summary: I've worked on a variety of tools or tool-like communication aids which I frequently wish were better known. Therefore, I'd like to advertise, give some demos, show off some tricks, and request some criticism, suggestions, and patches! --Michael Stone 17:18, 29 October 2008 (UTC)

• How much time is needed? 1 hour

Develop activity

Develop activity

Description - Quick discussion of the status and plans for the Develop activity. As time gets closer I will narrow down the topic, but at a minimum it will include discussion and request for suggestions of how best to make this a tool that real XO developers use

How much time is needed 60-90 minutes

Who can lead the discussion - Jameson Quinn

What preparation and materials should be created latest version of Develop, presentation with description of designs for planned features.

Automated testing tools

--User:Mchua and/or the QA team (Kim, Joe, Frances) - what tools are being used now and where to find howtos on using them, what tools would you like to see made/improved, how should test automation fit within our develop/test/release workflow, what testing tools can be developed and/or run by the community.

• Reviewed 10/29 - tentative status - Yes, Follow up owner - Mel
• Time: 60-90 minutes should be sufficient for both demos and discussion combined.
• Who: Mchua and the QA group can demo what the QA group is using right now, send a call for/invite/ authors and users of existing testing tools to give mini-stand-ups during this time, and moderate discussion.
• Prep: Call for (and choose/schedule) mini test-tool demos, prep demo spiels for existing QA tools (I'll have to do this anyway regardless of an XOCamp presentation, for community test)... some code customization to make tools work (better) for OLPC will likely be needed. Mchua

Languages - 2 hours

i18n and l10n: 9.1 and beyond

The areas I would like to cover include:

• Input methods: Out current input system (XKB) is not enough for Chinese/Japanese/Korean, and even existing customers like Ethiopia have needs which are met with considerable difficulty with XKB. For 9.1, I propose that we switch to SCIM[1], which should take care of most (if not all) of our current requirements.
• Multiple, non English fallback languages: Many of our users will probably be multilingual. A Aymara speaker would like to see the UI strings falling back to Spanish translations in absence of Aymara instead of the normal, default English. We have the existing infrastructure in our core i18n infrastructure, implementing this is simply a matter of making changes in Sugar (and maybe Rainbow).
• Language packs: The current system of language packs is not very reliable (it overwrites the original translations in the system, installations cannot be easily undone, no versioning, etc). I want to switch to a RPM based language pack system for 9.1, which will be easier to deploy (especially if the customization key mechanism gets support for RPM). This will require support for multiple locale directories, and I'll talk about that as well (Ubuntu uses a similar approach - I plan to reuse their patches if possible).
• User modifiable translations: There has been a number of ideas on this - initially (during my last visit to 1CC), we were thinking of a "Translate Activity" which would let children add/modify translations, and optionally let them share the translations over the mesh. SJ and Scott have recently suggested a wiki-like editable UI, which would, definitely be much cooler ;-). I want to brainstorm on this, and try to figure out the amount of time we need to do this, the advantages, risks, tradeoffs involved etc.

Power management

Summary: Continuing to evolve software to wring all potential power savings out of the hardware. Timed wakeup, allowing screen blanking to recover power and allowing more aggressive suspending. Measuring power usage to avoid regressions. testing for power against real world usage, pushing the remaining suspend-related bugs to completion. Keeping a close eye on software and hardware needed to really reduce power in Gen2. Also includes - the power button is currently underutilized. It should allow either shutdown or suspend of the laptop, with the help of an on-screen dialog or menu. [1]

eBook Reader

Three parts below need to be combined. Gregorio 21:45, 12 November 2008 (UTC)

Martin is very keen on this topic. We need something really compelling, standard and compatible for OLPC and all/most other viable platforms to win. Currently, every content project creates their own viewer (often webbased). We want to be able to show the content from a thousand sources, through a single viewer. We need something so easy for content creators to embrace, and so obviously good that they embrace it.

What does an electronic textbook look like?

Since the 1960s there have been experiments in high-powered educational software, but not a lot of textbook development that integrates this software into the text, and very little classroom experience. This session will look at the available materials, the types of software and content available, and the implications for future curricula.

What do we know? What examples do we have and what do they show us?

What opportunities can we see? How do we make this happen? What questions should we ask next?

Examples:

• Edison Talking Typewriter to teach reading and writing to pre-school children
• Ken Iverson's textbooks, Arithmetic, Algebra, and Calculus
• Smalltalk and the Dynabook concept
• Matlab, Mathematica, and other powerful software
• Notebook and workspace formats and capabilities
• Teaching programming to children: Smalltalk, Logo, APL, others

Theory of Activities

What's an "Activity"???

I've long wondered about the ambiguities and puzzles inherent in the notion of 'activity' rather than 'application'. Therefore, I'd like to talk about them! --Michael Stone 17:18, 29 October 2008 (UTC)

Activities as Building Blocks

If one chooses to regard Activities as the "basic building blocks" of learning experiences, then it seems natural to wonder how these blocks can be glued together into larger learning structures. --Michael Stone 17:18, 29 October 2008 (UTC)

Not sure who can present these. Michael, do you want to prepare the talk? GS.

Community

Why it matters

In my view it is the whole bottom line, la raison d'être of the whole project. No matter the XO and us are agents in developing scientists, artists, lawyers, whatever (who anyway are wont to migrate North ASAP), if there is not a process of community getting built among people who are not familiar with the culture and processes of collaboration, we are for naught, except maybe in making things worse. And of course, it is not at all just about sharing an activity, which is a software/hardware issue, it's the whole concept of building things together, sharing, being open to give and take, losing the "no te metás" (don't get involved) mentality.
