My journey with OLPC and Sugar

I’ve lost count of how many times the demise and resurrection of OLPC and Sugar have been proclaimed and celebrated. What makes these projects tick?  Grow?  I ask myself this question whenever I start feeling burned out, wondering why I remain attached to the project and this green machine.

My own journey with OLPC, Sugar and all things related, has been underway for years. I’m a techie at heart, a “thinly-disguised” business school professor, teaching IT strategy and researching business models and consumer behavior. Every once in a while, I’ll sit down and compile a kernel, or run a packet sniffer.  (What can I say? It’s instant gratification and a lot more fun 🙂

I think of the tech as the supply side of my interest: The XO makes for a great technology platform. The mesh (whether 802.11s or ad-hoc), suspend with the screen lit, robustness, low power, etc. is all very cool. Cool enough for a grown man to walk around with a funny-looking green machine slung around his shoulder.  The software stack too is amazing, flexible, free. The content is rich. Wikipedia in a box? Awesome! The tech definitely keeps me tethered.

Then there’s the demand side: a part of my family lives in rural India, in Bhagmalpur. A village where I have seen the simple life. Clean air, good food, quiet living. Its also stricken with poverty, sanitation issues, water shortages, and seriously untapped ingenuity.

As a kid, I used to hang around Maggu, while he milked a water buffalo, or Bahadur, while he made gold jewelry on a block of coal. Today I wonder what Maggu would do if he could learn about the rest of the world and its dairy achievements. How Bahadur’s family could save the lost art of rural goldsmiths. Would they benefit from a peek into that Wikipedia in a box? You bet. In my mind, I can savor the possibilities of the supply, and imagine what it can do for the demand. I speak with my friend Javier Cardona about IEEE 802.11s, with Maggu on my mind. These worlds must meet.

Finally, there’s the catalyst: my daughter Mira, now age five. She could open the XO, power it on, and turn it around into tablet mode when she was two. At three, she could play Implode on the XO with a finesse that amazed me. Children are like sponges; they soak up everything, and have incredibly simple solutions in their heads.  I cherish Mira’s curiosity and ingenuity, and she has been my catalyst for inspiration.

So that is my supply, my demand, and my catalyst. My story and my guide.

Every volunteer has her own story. Many come and go, some stay, but all leave a mark on the overall process. They all help us steer projects in new and meaningful ways. For instance, a little over two years ago in Austin the XO manual was written by volunteers to pave the way for a new kind of global user.  Sugar hackers and tech writers of all flavors funded their own way to Austin, to gather and create a resource that is used everywhere today.

A year later, volunteers ganged up in Washington, DC (again on their own dime) to create 30+ OLPC community deployment success stories, compiled into the “Class Acts” repository of tips & tricks.  I’ve dipped into this pool myself, asking my students to convert some of these into one-pagers. If you need a handout for a neighbor or school principal, grab this and print it!

And now we’re preparing for a larger community event, with volunteers from all parts of the movement and from around the world, at the OLPCSF Community Summit. Stay tuned for details and a summit update tomorrow.

OLPC SF Community Summit 2010, Oct 22-24

OLPC’s global community of contributors and volunteers is gathering for its largest ever meeting to date, on the weekend of October 22-24, in San Francisco! Thanks to the OLPC San Francisco Community led by Professor Sameer Verma, and our gracious host San Francisco State University.  If you want to take a stand for global education rights For All in this 21st century, now is your time — OLPC’s Global Community is a friendly and supportive network inviting you too to Stand & Deliver:

The OLPC SF Community Summit 2010 will be a community-run event bringing together educators, technologists, anthropologists, enthusiasts, champions and volunteers. We share stories, exchange ideas, solve problems, foster community and build collaboration around the One Laptop per Child project and its mission worldwide.

Now we’re taking the next step, bringing together the voices of OLPC experience, Sugar Labs, the Realness Alliance — and yourself. Check out our growing list of social entrepreneurs who’ve already signed up from Uruguay, Peru, Paraguay, Argentina, Nicaragua, Africa, Afghanistan, India, Philippines, France, UK, Italy, Belgium, Austria, Canada, Birmingham and beyond.  Then please consider joining us, adding your own contribution/testimonial and photo!

Repair workshop this Saturday at OLPC HQ

This Saturday we’re holding a repair workshop and presentation — if you haven’t torn down your XO and rebuilt it from the motherboard up, now’s your chance to try on someone else’s machine — and to learn how to break down and rebuild one in under half an hour, with nothing but a Phillips screwdriver!

We’re holding a workshop Saturday through the early afternoon. RSVP if you’re planning to come. The machines worked on will primarily be XO-1’s, since those are still the machines most likely encountered in the field. The major differences on the 1.5 make these sorts of repair much easier, not more complex — there’s little reason to take apart the bottom on a 1.5, for instance, since the keyboards just pop out.

Papua New Guinea’s Jim Taylor Primary School

Earlier this month, Laura Hosman, an assistant professor following OLPC,  wrote an eloquent two-part series about her visit to the Jim Taylor Primary School in Kisap, Papua New Guinea, an hour’s drive from Mount Hagen.  This has the potential to be one of our most interesting rural deployments — and well run, as are all of the Oceania projects.  It is interesting to see how they are using their casually-scattered solar panel array.

XO power data: power draws for plugged-in laptops

Guest post by Richard Smith

We’ve finished testing power consumption while plugged into a 230V ac wall outlet for the XO-1 and the XO-1.5. The new machine performs well while suspended, and suspends very smoothly.   The 1.5 charges faster and using less power to charge the same battery.  It also draws slightly more power when in high use, thanks to its variable CPU.

See the chart below, which includes the power draw of the AC adapter.  Battery-only numbers will be significantly lower, in particular for idle and suspend, but are a bit harder to measure cleanly.  There is no comparison chart for that yet.

Power draw at the wall (XO + adapter + backlight)

Scenario XO-1 XO-1.5
Full charge 56 Wh 47 Wh
Idle 8.5W 7.2W
High 9.5W 9.7W
Suspend 5.2W 2.85W
  • Full Charge: The amount of energy it takes to completely charge a dead battery, using an adapter (power needed for bulk charging of batteries may differ).
  • Idle: Laptop sitting at the Sugar home screen, with power management disabled, backlight on full, charging.
  • High: Laptop running the Record activity’s “preview” mode.  Power management disabled, backlight on full, charging.
  • Suspend: Laptop with power management enabled, suspended, charging.

Calculating low-power options:

  • The backlight draws close to 1W – you can shave that off of the idle and high numbers turning it off.
  • Most of the power draw on suspend is to the adapter – you could view that as an upper bound on how much to factor out of the other numbers for battery-only power usage.
