Thoughts on providing at-cost hardware to developers

The developers program is usually able to send one free XO per developer. We would like to allow individual developers, and larger organizations like software companies and research labs, to purchase additional XOs at cost independently of the G1G1 program.

As a start, game console manufacturers are an example of organizations which must distribute proprietary hardware on a limited basis to developers. Their programs generally look something like this:

Development studios who would like development hardware (say XBox360 devkits) must first apply to become part of the developers program. This involves providing credentials (a publishing contract for example), and then signing a NDA. They are then given access to a private development area, forums, support group, etc., and are allowed to purchase hardware through the developers program. The hardware is not theirs, they must agree to send it back in 5 years or so when no longer needed, but if it breaks it will be fixed without charge.

This could be adjusted to fit OLPC's open nature as follows:

Developers who would like an XO must first apply to become part of the developers program. This involves providing credentials (a resume), contact information and a project plan. They are then sent one free XO, and are allowed to purchase a fixed number (3?) of additional XOs at cost after signing and returning an agreement not to resell XOs acquired through the developer program. The XOs are theirs to keep. Development groups (e.g. research labs) may apply using the same system, and will be granted a larger (9?) fixed purchase amount. Larger purchase requests will be handled on an individual basis.

Questions

• Can we legally hold people to not resell XOs they receive through the developers program? I'm concerned after seeing G1G1 XOs on EBay for $400, some people might try to take advantage of the developer program.

Please add reference to Development Wiki

Perhaps you could say something like this:

If your interest is primarily on doing some systems level or applications level coding, then join one of the projects on our Hosting Wiki.

You might want to add a link to this photo gallery. It shows how one developer set it up inside an old 286 case. There appear to be two boards in the photos but one is a photo explaining all the interface connectors.

Hardware Developers' Program

Are there any intellectual property restrictions to a private firm beginning production of these machines? Are the details of the Hardware specification available in machine-readable format?

I would like to start a Production Commons to begin independent development of this hardware (including modified versions) as soon as possible. Are the design specifications Free as in Freedom so that we may proceed? Ownut

Good question. Open Hardware like Arduino is more in line with the project goals... Lowering the entry hurdle/ barrier would help not hurt the project... Spinoffs might be merged back into the next release, hardware development is learning too...

St. Nick says the warranttee doesn't start til you open it up... Crack the box, or just start the machine?

BIOS section should be revised for LinuxBIOS

This page should contain a link to Upgrading_to_LinuxBIOS rather than saying that people shouldn't mess with their BIOSes.

SELinux

SELinux vs 0-day attacks is uninteresting. Attacks which would normally succeed will still succeed under SELinux control, with limited privileges; some possibilities:

• Burn CPU until power goes out (but it dies as well)
• Kill other user processes (i.e. the Web browser being used to take a test)
• Infect the user's account (i.e. if we break in through Firefox or something) and start on every log-in
• Destroy user data
• Constantly write to flash, until it starts to suffer infant mortality (several weeks/months of this maybe, but still bad; plus we're killing power)

Deploying other enhancements like stronger address randomization and stack smash protection will help this in general. Ptmalloc (in glibc) is hardened against heap corruption and double-free() already.

What you can use SELinux for is execmem,execmod,execheap,execstack protections to control memory execution; but this won't work entirely without an NX bit. Port the emulation from Exec Shield (weak, stack only--usually, sometimes no protection) or PaX (Strong, fine-grained per-page, but more CPU intensive and likely to be a pain due to the very few TLB entries); or run full PaX and possibly GrSecurity.

Regarding the serial cable, please do `s/DB9/DE9/`, and also state whether the connector is Male or Female. A DB9 (D-shell, size B, 9 pins) would be the size of a Parellel port... as opposed to DE9 (D-shell, size E, 9 pins) which is the size of a VGA connector (aka DE15). Sladen 09:33, 31 May 2006 (EDT)

I found the reference to OOM killer obscure. It seems to refer to "Out of Memory Killer," but I don't know what will make it less naive, more sophisticated for OLPC needs.

Right now, the heuristic used by the kernel to choose what to shoot has no information provided by user space: it makes some guesses. Something much better is clearly possible. - jg

I'd say the better thing is to set vm.overcommit_memory=0 and be done with it. - Slamb 12:17, 5 August 2006 (EDT)

"IPv6 support, and service discovery, which are very important to us." I am interested in helping with IPv6, even if just testing for now. Any suggestions where to get started? Specifically, is there any ongoing effort to address service discovery? Is there any interest in instrumenting the stack for systems management? Please point me to an appropriate place, if this is off topic.

Fbkintanar 00:20, 13 June 2006 (EDT)

I think both Marcelo and our SOC student have interest in the stack area.

We're using the Avahi library to do mdns/zeroconf stuff. You can test it on IPv6, and there are missing pieces to connect it with dns for higher scaling. Get in touch with blizzard. -jg

In the Background section is the following.

..., which is aimed at individual FOSS developers or research organizations.

Yet in the How to apply section is the following.

3. Employer

Could you please consider rewording this to say

3. Employer (if any)

or to

3. Employer (if this application is related to any employment you may have)

as at present it does provide the possible interpretation that an applicant must have an employer and that the employer is involved in the application.

I feel that this is important as otherwise the project could come by custom and practice to have a "not representing an organization" discrimination ambience.

fixed. Thanks.

Ideas to Extend Developers Program

Some of these ideas pertain more to a grassroots organization than the OLPC NGO.

Engineers in developing nations need more financial incentives to participate in Open Source projects than engineers in the developing world require (often none), typically due to the financial pressures placed on them by their families. We need to convince both student developers and their teachers that they should switch their academic focus from J2EE to Python.

Benefits for Core Developers:

• Certificate from an internationally recognized technical university -- ideally MIT.
  • Other possibilities are the MIT Media Lab or Open Source Lab at Oregon State. Certificates are a big deal in the developing world.
  • Certificates could be based on amount of code contributed to dev.laptop.org, participation in code reviews, hardware development etc.
• Discounted internet access and possibly provide extra UPS -- this benefit would vary country by country and a grassroots organization would have to coordinate it.
• Discounted or free examinations for related IT certifications for accomplished developers
  • Red Hat Certified Engineer (RHCE)
  • A Python programming certification -- I know this doesn't exist but OLPC is a good enough reason to start one
• Internships -- We intend to offer internships at OLPC Nepal but this may not be feasible in a country without an active OLPC organization.

Events to Stimulate Interest in OLPC

• Regional and international events to stimulate interest in development, should emphasize commercial value of skills learned from working on OLPC, for example: "learn Python and you could eventually work for Google, Red Hat, etc."
  • Regional and national programming contests with significant prize money, for example in Nepal $2000 USD would be a substantial prize and huge incentive
    • Separate contests for Activity Development, hardware development, and power systems development, could be organized similar to CSIDC
    • Pie-in-the-sky idea -- regional Google Summer of Code style summer camps focused exclusivelyon OLPC
  • Regional or national programming hackfests and sprints

poor firmware/filesystem update info

It's not really clear what version I should be using for what purpose. I'm guessing that some revisions are best for app development, others best for sugar development, and a few will brick the machine. The wiki doesn't even have a changelog. According to the tinderbox data, which looks too awful to really believe (broken script?), all the recent versions are very bad.

I got build 239 with the B2. I was about to update to that when I noticed I already had it. Is that about the best for app development?

A version of gcc with -mcpu=geode would be good. (kids should have it too BTW)

Article is now linked from sidebar. Cleanup needed.

The article is now liked from the sidebar, dramatically increasing its visibility. Thus it needs cleanup. Until a moment ago, it didn't have an intro paragraph. It was written before sugar-jhbuild existed, and so only talks about emulation. The hardware release notes linked to are for BT-2. Etc. Basically, this seems an "old and moldy" page which has now gone high profile, and so needs work. MitchellNCharity 00:25, 17 August 2007 (EDT)

Fold into the Developer's Handbook, focus this page on its topic

This page is rapidly molding away to obsolescence.

My intention is to make the sidebar link to the Developer's handbook. This page, then will be solely about the actual "Developer's Program", the program that gives access to hardware and project support services.

A fine plan. We're also revisiting the developers program process, to make that more transparent and share the vetting process and the project ideas it generates with the community.

The hardware build discussion stuff will likely move to a separate page (e.g. Hardware or Hardware/Prototypes). The general introduction stuff should be using the general introduction to the machine, figure out where that is...

Perhaps a page of OLPC:getting started?

I'll likely be working on this on Wednesday, so if you have an objection, make it soon and loud. I'm guessing I'll need an admin to do the actual side-bar changes.

True enough. We need more wiki admins... feel free to nominate the good editors you know. adminship is no big deal; it's just a way to help everyone edit effectively. --Sj talk to me 19:39, 24 December 2007 (EST)

Feature requests for projectdb

After going through a round of applications in the projectdb as an admin, I've got a few feature requests that would be awfully handy.

• Do people automatically get notified of their project status/etc. being updated? Can we add this?
• Can we track the history of a project - for instance, this edit was made by this person at this time, this suggestion was made by this person at this time?
• I'd like to be able to merge projects (for instance, multiple partners working together submitted separate applications for exactly the same project).
• Automatic "click a button" spreadsheet generation of all approved projects that have not yet been spreadsheeted.

Mchua 16:16, 22 May 2008 (EDT)

Current distribution process

• Review latest round of submissions to the projectdb, approve those that qualify
• Export approved projects into csv files, one per destination country (one line per project per country)
  • The csv files should contain the following fields:

CustOrdNbr	 ShipName	 ShipAddr1	 ShipAddr2	 ShipCity	 ShipState	 ShipZip	 ShipPhone

• • Details:

    OrdNbr should be DE90000000 + the project number

    Addr fields should be no longer than 30 characters

    State should never be empty but should contain an "x" if there is no state;

    Phone should contain only digits, no + symbols; and should use "011" before international country codes

Updating the contributors program

from discussions with wade

Sugar : designs are progressive and exciting, implementation sparse. Sugar has been often ignored on tech news sites. Our resources are focused on the platform rather than the user experience. The barrier to entry, work required before the first successful commit, must be overcome by outreach and guidance [and] open development process.

Three key pillars are recruiting contributors, marshalling efforts, and channeling recognition

Recruiting

Thousands of experienced programmers would absolutely love to work on Sugar, activities and content. reach them and help them get a development environment or contribute [once] to a project.

Target communities with high potential. For programmers, gamedev.net and Game Illuminati and The Chaos Engine; Google Summer of Code to reach college students. Universities with tech programs, in developing countries, and Python user groups. Experienced programmers who buy XOs for their children or for themselves [G1G1]. schools and deployments actively using XOs who may have development resources. ensure they are adequately served and fit in with the Sugar community.

Recruit to each community. Game developers react well to contests and challenges: "Free XOs and T-shirts to the first team to get Blender to render <this scene> in less than 1 second". University students respond to certificate programs for Python and User Interface development, and to online internships which look good on resumes.

Marshaling

Community projects [often] start with the best intentions, are 90% complete but lose momentum. the second 90% is left once you finish the first 90%. We must [help] finish projects that are nearly complete, and fix those once stable [that] decay.

Idleness causes contributors to lose interest. engaged with a sense of momentum, they will continue actively. We must champion important tasks and pair recruits with mentors who can keep them busy.

Finally, we must streamline development so contributors do not get stuck. hosting, translation and testing must be available [and reliable], and the means to provide those services available [distributedly]. One way: build Translate, Develop and Bug Report activities into the XO. Then at any time users can a) translate or re-translate a string, b) develop and submit a patch, or c) report a bug and attach data.

Recognition

Contributors must know their work is appreciated. Highlight each contribution via weekly email and the wiki, watching Git commits and Trac updates.

The mentors team will also have responsibility to confer status titles on participants and projects. For example, 'Featured' status (quality, value) and place on the Activities page. Or an 'OLPC Fellow' [title], and a special tag on their User page.

Organization

This work will fall under the jurisdiction of the contributors program, facilitated by OLPC and overseen by the community. This program will unify distributed community development of Sugar software and content, guidelines for reviewing and creating great material, and identification and assignment of open tasks and potential bounties.

The public face of the program will be the Contributors and Developers pages on the OLPC wiki. This portal will highlight accomplishments and identify high value tasks for people to work on. It will provide organized links to help new contributors find projects and mentors and get started.

The program will form teams of welcomers, reviewers, and mentors from community and staff. These teams will identify new contributors from first inquiry and/or contribution, and work with them to help them stay active. Mentors will be assigned a list of community members to assist based on specialty, workload and other considerations.

Feature requests

• Easier batching of a set of requests for review, and a label indicating they are explicitly out for that week's review.

  from Mel.

cancel Peter Robinson's request

Please *cancel* Peter Robinson's request. It was accepted but has not shipped. He has now obtained an XO through RT#30642.

How does someone become a community mentor?

I like that you can "view source" for the process and help with the review, and would love to see the same for mentors - who are they, how are they chosen, how can you become one? Mchua 16:52, 3 March 2009 (UTC)

Combined Feedback

For other things on this page. Apple has a developer program that requires student status... When I was a university student I used it, didn't require much and got some things like developer tools CDs, t shirt, new OS X versions in beta or similar. Costs to Apple to send to developers. My Beige G3 (~$2k invested in 1997), now sits idle, but did finish degree with it... Long story... Software developed in Java still runs unmodified 10 years later, not impressive, retro, but...

Anyway, other (general) hardware developers offer development boards for some cost, no requirements besides buying it. Learn as one wishes to learn... Others probably have sales version for projects buying large number of hardware, or free hardware with commitment of project using nnn ICs, boards, etc...

If XO is to thrive as a platform, given that OLPC USA doesn't really exist (pitched it to Feds at FOSE2008/ FOSE2009), and learning is universal (i.e. not defined by country boundaries), then need to do Something. The contributors program has not been responsive (to me personally), and trying to just participate in chats, get knocked off, though my questions are probably rather basic, my experience, though dated, might help others...

Fat XO (1.5) will be a more general purpose machine and don't see why having more out in the world would not be a good thing... Debian social contract is not fixed on how one gives back. Showing the machine (just about every time I open it in the US/ DC) I get questions, and end up doing a mini demo. How many times have I used it in the last 1.5 ~2 years?

And can't get parts to fix my now over travelled little machine (XOExplosion ignoring me). Lending machines are not really appropriate for hardware hacking, camera not working, other issues, so would need something and no sense in getting older hardware...

Also, want touchpad development capable hardware... Kids of <5 yo (+ adults) want to touch the screen, XO-2 is going to be smaller, faster, touchscreen like, and why not get started? All the apps/activities are going to automagically now be touch instead of mouse/ trackpad capable? System call changes?

And keeps up with the intel ;-/ We have no choice but to buy the successor netbooks if can't get parts, or original hardware...
