One Laptop per Child

Congratulations to Uruguay on the 10th anniversary of its national OLPC program, Plan Ceibal! Feature: Uruguay marks 10 years of bridging digital divide.

We want to share this amazing article. Congratulations to Uruguay on the 10th anniversary of its national OLPC program, Plan Ceibal!

By Gerardo Laborde

MONTEVIDEO, May 14 (Xinhua) — Uruguay this month is celebrating the 10th anniversary of a national program that has made Internet available to the masses by providing all elementary school students with a laptop.

The national program, called Plan Ceibal, in conjunction with the global nonprofit initiative called One Laptop Per Child (OLPC), made Uruguay “the first country in the world to provide one laptop to every primary school student,” according to OLPC’s website.

“I must admit that, at the beginning, I never imagined a plan so complete and well executed,” OLPC’s founder, the U.S.-born Nicholas Negroponte, said during a visit to Montevideo this week.

Negroponte, who is also the founder of MIT’s Media Lab, said one of the factors that helped to make the plan a resounding success in Uruguay was President Tabare Vazquez, who was serving his first term (2005-2010) when the plan was first adopted.

Vazquez was adamant about the scope of the program, insisting it should cover every child, according to the state Uruguayan News Agency (UyPress).

“Nobody else did that. That is extraordinary,” said Negroponte.

In announcing the plan in December 2006, Vazquez said that as of 2007 “the fundamental school supply our children are going to have is going to be this computer.”

The first green-and-white laptops, which cost 100 U.S. dollars to make, were distributed in May 2007 at a school in the small town of Villa Cardal, in the southern department of Florida, home to just 500 inhabitants. But soon schoolchildren throughout the country had a “ceibalita,” as the laptops were called.

The first three students to get a laptop were Micaela Rodriguez, Rocio Martinez and German Arrua, today aged 17, 18 and 19, respectively.

All three agree the laptop marked a turning point in their educational life.

“They came to be used for all the day’s work,” Rodriguez told national radio network Radiodifusion Nacional del Uruguay (RNU).

“With a computer, we could find out about many things that we didn’t know existed in Uruguay,” she added.

Martinez agreed, saying the Plan Ceibal, a Spanish backronym that stands for Basic Informatic Educative Connectivity for Online Learning, “was a great help” for studying.

Arrua, meanwhile, recalled using his laptop to take pictures.

The president of Plan Ceibal, Miguel Brechner, said prior to the initiative, “only 9 percent of children from the poorest households had access to a computer. Today, more than 90 percent of that population does.”

Thanks to its effectiveness, Plan Ceibal was expanded to secondary school students and since 2016 is being used to teach the elderly.

According to Negroponte, two other factors helped make the program a success in Uruguay, including developing the needed infrastructure, which state telecom Antel was tasked with doing.

The third factor was the country’s belief in the advantages of promoting equality, he said.

“Due to these three things: Vazquez, equality and the telecommunications, this project turned into what it is. And it helped us in many aspects, and that’s why I want many other countries to copy this experience,” Negroponte said.

Uruguay “has become the byword” for progressive educational programs, he said, predicting that “in 20 years, Uruguay will be producing the world’s most creative people.”

‘Til All Are One

Creating an Education Programme

OLPC Australia had a strong presence at 2012 in Ballarat, two weeks ago.

I gave a talk in the main keynote room about our educational programme, in which I explained our mission and how we intend to achieve it.

Even if you saw my talk at OSDC 2011, I recommend that you watch this one. It is much improved and contains new and updated material. The YouTube version is above, but a higher quality version is available for download from Linux Australia.

The references for this talk are on our development wiki.

Here’s a better version of the video I played near the beginning of my talk:

I should start by pointing out that OLPC is by no means a niche or minor project. XO laptops are in the hands of 8000 children in Australia, across 130 remote communities. Around the world, over 2.5 million children, across nearly 50 countries, have an XO.

Investment in our Children’s Future

The key point of my talk is that OLPC Australia have a comprehensive education programme that highly values teacher empowerment and community engagement.

The investment to provide a connected learning device to every one of the 300 000 children in remote Australia is less than 0.1% of the annual education and connectivity budgets.

For low socio-economic status schools, the cost is only $80 AUD per child. Sponsorships, primarily from corporates, allow us to subsidise most of the expense (you too can donate to make a difference). Also keep in mind that this is a total cost of ownership, covering the essentials like teacher training, support and spare parts, as well as the XO and charging rack.

While our principal focus is on remote, low socio-economic status schools, our programme is available to any school in Australia. Yes, that means schools in the cities as well. The investment for non-subsidised schools to join the same programme is only $380 AUD per child.

Comprehensive Education Programme

We have a responsibility to invest in our children’s education — it is not just another market. As a not-for-profit, we have the freedom and the desire to make this happen. We have no interest in vendor lock-in; building sustainability is an essential part of our mission. We have no incentive to build a dependency on us, and every incentive to ensure that schools and communities can help themselves and each other.

We only provide XOs to teachers who have been sufficiently enabled. Their training prepares them to constructively use XOs in their lessons, and is formally recognised as part of their professional development. Beyond the minimum 15-hour XO-certified course, a teacher may choose to undergo a further 5-10 hours to earn XO-expert status. This prepares them to be able to train other teachers, using OLPC Australia resources. Again, we are reducing dependency on us.

OLPC Australia certifications

Training is conducted online, after the teacher signs up to our programme and they receive their XO. This scales well to let us effectively train many teachers spread across the country. Participants in our programme are encouraged to participate in our online community to share resources and assist one another.

OLPC Australia online training process
Online training process

We also want to recognise and encourage children who have shown enthusiasm and aptitude, with our XO-champion and XO-mechanic certifications. Not only does this promote sustainability in the school and give invaluable skills to the child, it reinforces our core principle of Child Ownership. Teacher aides, parents, elders and other non-teacher adults have the XO-basics (formerly known as XO-local) course designed for them. We want the child’s learning experience to extend to the home environment and beyond, and not be constrained by the walls of the classroom.

There’s a reason why I’m wearing a t-shirt that says “No, I won’t fix your computer.” We’re on a mission to develop a programme that is self-sustaining. We’ve set high goals for ourselves, and we are determined to meet them. We won’t get there overnight, but we’re well on our way. Sustainability is about respect. We are taking the time to show them the ropes, helping them to own it, and developing our technology to make it easy. We fundamentally disagree with the attitude that ordinary people are not capable enough to take control of their own futures. Vendor lock-in is completely contradictory to our mission. Our schools are not just consumers; they are producers too.

As explained by Jonathan Nalder (a highly recommended read!), there are two primary notions guiding our programme. The first is that the nominal $80 investment per child is just enough for a school to take the programme seriously and make them a stakeholder, greatly improving the chances for success. The second is that this is a schools-centric programme, driven from grassroots demand rather than being a regime imposed from above. Schools that participate genuinely want the programme to succeed.

Technology as an Enabler

Enabling this educational programme is the clever development and use of technology. That’s where I (as Engineering Manager at OLPC Australia) come in. For technology to be truly intrinsic to education, there must be no specialist expertise required. Teachers aren’t IT professionals, and nor should they be expected to be. In short, we are using computers to teach, not teaching computers.

The key principles of the Engineering Department are:

  • Technology is an integral and seamless part of the learning experience – the pen and paper of the 21st century.
  • To eliminate dependence on technical expertise, through the development and deployment of sustainable technologies.
  • Empowering children to be content producers and collaborators, not just content consumers.
  • Open platform to allow learning from mistakes… and easy recovery.

OLPC have done a marvellous job in their design of the XO laptop, giving us a fantastic platform to build upon. I think that our engineering projects in Australia have been quite innovative in helping to cover the ‘last mile’ to the school. One thing I’m especially proud of is our instance on openness. We turn traditional systems administration practice on its head to completely empower the end-user. Technology that is deployed in corporate or educational settings is typically locked down to make administration and support easier. This takes control completely away from the end-user. They are severely limited on what they can do, and if something doesn’t work as they expect then they are totally at the mercy of the admins to fix it.

In an educational setting this is disastrous — it severely limits what our children can learn. We learn most from our mistakes, so let’s provide an environment in which children are able to safely make mistakes and recover from them. The software is quite resistant to failure, both at the technical level (being based on Fedora Linux) and at the user interface level (Sugar). If all goes wrong, reinstalling the operating system and restoring a journal (Sugar user files) backup is a trivial endeavour. The XO hardware is also renowned for its ruggedness and repairability. Less well-known are the amazing diagnostics tools, providing quick and easy indication that a component should be repaired/replaced. We provide a completely unlocked environment, with full access to the root user and the firmware. Some may call that dangerous, but I call that empowerment. If a child starts hacking on an XO, we want to hire that kid 🙂


My talk features the case study of Doomadgee State School, in far-north Queensland. Doomadgee have very enthusiastically taken on board the OLPC Australia programme. Every one of the 350 children aged 4-14 have been issued with an XO, as part of a comprehensive professional development and support programme. Since commencing in late 2010, the percentage of Year 3 pupils at or above national minimum standards in numeracy has leapt from 31% in 2010 to 95% in 2011. Other scores have also increased. Think what you may about NAPLAN, but nevertheless that is a staggering improvement.

In federal parliament, Robert Oakeshott MP has been very supportive of our mission:

Most importantly of all, quite simply, One Laptop per Child Australia delivers results in learning from the 5,000 students already engaged, showing impressive improvements in closing the gap generally and lifting access and participation rates in particular.

We are also engaged in longitudinal research, working closely with respected researchers to have a comprehensive evaluation of our programme. We will release more information on this as the evaluation process matures.

Join our mission

Schools can register their interest in our programme on our Education site.

Our Prospectus provides a high-level overview.

Interview with Australian Council for Computers in Education Learning Network

Adam Holt and I were interviewed last night by the Australian Council for Computers in Education Learning Network about our not-for-profit work to improve educational opportunities for children in the developing world.

We talked about One Laptop per Child, OLPC Australia and Sugar Labs. We discussed the challenges of providing education in the developing world, and how that compares with the developed world.

Australia poses some of its own challenges. As a country that is 90% urbanised, the remaining 10% are scattered across vast distances. The circumstances of these communities often share both developed and developing world characteristics. We developed the One Education programme to accommodate this.

These lessons have been developed further into Unleash Kids, an initiative that we are currently working on to support the community of volunteers worldwide and take to the movement to the next level.

Slides on the Chamelium board

Yesterday I gave a short talk about the Chamelium board from the ChromeOS team, and thought that the slides could be useful for others as this board gets used more and more outside of Google.

If you are interested in how this board can help you automate the testing of your display (and not only!) code and hardware, a new mailing list has been created to discuss its uses. We at Collabora will be happy to help you integrate this board in your CI lab as well.

Thanks go to Intel for sponsoring the preparation of these slides and for allowing me to share them under an open license.

And of course, thanks to Google's ChromeOS team for releasing the hardware design with an open hardware license along with the code they are running on it and with it.

Writing Sugar Documentation with a Neural Network

Believe it or not, Sugar has documentation. But what if we could have more documentation? Maybe we could use a Recurrent Neural Network to learn form the docs that we already wrote, to write new docs? We'll, you can't say no if you don't try!

Let's do it!

We are going to use a library called Torch RNN, which basically does everything for us:

docker pull crisbal/torch-rnn:base
mkdir -p $HOME/torch-rnn/sugar-data/
cd $HOME/torch-rnn/sugar-data/
sudo chcon -Rt svirt_sandbox_file_t $HOME/torch-rnn/sugar-data/

sudo docker run --rm --tty=true --interactive=true --volume $HOME/torch-rnn/sugar-data:/data crisbal/torch-rnn:base bash
# Now we are running inside the pre-setup docker container

Great, not quit the docker container, we'll come back to that later. We first need to extract the data from the help activity into a single text file to train our network:

git clone --depth=1
find help-activity/source/ -type f -name '*.rst' -print0 | xargs -0 cat > input.txt

If you open the input.txt file, you will see that it is a pile of help documentation text. This will be used to train our network. Go back into the docker container (docker run ... from above) and now we can train the network:

# python scripts/ --input_txt /data/input.txt --output_h5 data/input.h5 --output_json data/input.json
Total vocabulary size: 117
Total tokens in file: 361025
  Training size: 288821
  Val size: 36102
  Test size: 36102
Using dtype  <type 'numpy.uint8'>

# th train.lua -input_h5 data/input.h5 -input_json data/input.json -gpu -1
Epoch 1.01 / 50, i = 1 / 5750, loss = 4.752145
Epoch 1.02 / 50, i = 2 / 5750, loss = 4.644123
Epoch 1.03 / 50, i = 3 / 5750, loss = 4.498253
Epoch 4.13 / 50, i = 360 / 5750, loss = 2.037364
Epoch 5.16 / 50, i = 478 / 5750, loss = 1.796518
Epoch 5.81 / 50, i = 553 / 5750, loss = 1.690430

While you're waiting, now is the right time to check out Presenter Club. With Presenter Club, you can make great presentations, faster - even faster than training this network! Presenter Club is the only speech first presentation app. Best of all, it is free as in price and free as in AGPLv3. Sign up for free while you wait!


So training the model is really slow. How slow? It took a good hour or longer on my laptop. Fun fact - if you thought your laptop was slow because it took long to compile WebKit, your laptop is not the best for machine learning :(

I trained it up to checkpoint 5750 (all the way until the training script stopped!). Then I generated a few examples from the following seeds:

So this is just random text for the most part. But it is important to appreciate what the network has been able to learn even with our tiny dataset:

  • The rst .. image:: syntax
  • The normal length of paragraphs and words
  • Full stops are followed by capital letters
  • Bullet points are a thing


So, this technology is probably not yet ready to replace our actual documentation, or even the contribitions of some GCI students! But this just highlights how exciting machine learning is. Problems that traditional programmers thought of as "hard" - like image clasification or translation - are now just as easy as collecting a training dataset. If you want a function approximated, then machine learning is your friend.

VC firms have said that mobile is eating the world, wearables are the future, IoT will change everything, and VR will eat the world. Not every claim has panned out for them. But I'm going to place my bets that machine learning is not only the future, but the past and present. We live in very exciting times.

5 Steps to Build Your Global Ecommerce Site

With the growing trend of internet and the proliferation of internet users, the business with e-commerce has been expanding. All the handy gadgets like mobile and tablets have further escalated the realm of e-commerce. Another major factor that has increased the pace of global online trading is the effective payment system. This helps the clients in getting the refined ways to pay for what they have ordered. With the use of state of the art tools and techniques available on the sites of global e-commerce, it has become easy for the customers to buy products which are not available in their local markets. But launching such website is not a piece of cake. There are many parameters that need to be analyzed before launching any global E-commerce site. It is imperative to delve into the detail of those five steps that helps to build an E-commerce site.

Assessing demand and supply

Before building an E-commerce site it is incumbent to analyze the demand and supply ratios for the products that are going to be launched by the site. For instance, it was observed that in China only a hand full of segments are available online. This presents that there is a lot of room available to build site of other much needed online retail segments by the clients. All such perspectives will enable the e-commerce operations to be successful not only in the local market but also the international market. Hence it is better to analyze and then select the products offered by the global E-commerce site under construction.

Product to be localized:

It is incumbent that the product should be made localized. This means that the product should make popular before launching it on the site. For instance, Mattel which is a toy making company launched Barbie doll in China. It was a complete failure because for Chinese girls this doll wasn’t attractive as this wasn’t as per the taste of the local people.

Site to be localized:

This means that the site should be localized in terms of language, style, and many shopping habits. It can be made clearer with the fact that if the site is unable to give a description of the products as per the language of the local people where most people would not understand English. This will eventually lead to failure of the site. So it is advised to hire a team for this purpose.

Accordingly, set the prices:

It is one the indispensable step. The site should manifest the price of the products as per the local currency. In order to enter the new market, it is important to launch the local prices for the successful business.

Privacy and data of the customer , to be focused :

As we all know that cyber safety has become a menace to the digital world. All the overseas customers want their personal data to be protected. So while building a global E-commerce site make sure to put privacy center messaging across the whole site and to hire a team to resolve privacy-related concerns.

Why writers are important for best internet marketing strategy

This is a world of technology and every person has access to the internet, so business owners also consider it an authentic and effective platform for advertising their products. There is so much competition around as everyone is offering a quality product, effective strategies, and every such service which is the requirement of a customer. Most of the aspects of a business depend on the success of its marketing position and the goal of a successful business is to improve this position.

Internet marketing is basically an online marketing strategy that promotes a brand, services or products through the websites. It involves many aspects of the website such as designing, advertising, sales, and development.

Need of a Good Writer

Writing is a better expression of ideas and this could grasp the entire world in a fist. It needs depth knowledge and greater skills to be on the top of the best writers. Writers, particularly of nonfiction subjects, have gained a lot from marketing as they know the best way to put all the pieces together. They are the crux of a successful business because of the following major aspects:

Inspire and Incite Action

Storytelling is a creative way to entice the customer for a particular product. The effective writers create the content in a contagious way that could grasp the readers and make them the regular customer of a particular product. They write each piece of a content using the inspirational, emotive, personal, and suspenseful stories. Such writers ignite the fire so strongly that the customers are compelled to stick to the company for a long lasting period.

Plan before they write

A good writer never merges the scattered pieces instead; he makes a contextual framework about a particular project before putting it on paper. The social media and the entire internet marketing always highlight the importance of quality writing, so the content writers are always under pressure to create a good and quality content for a company. An effective writer has always a properly documented strategy and they follow it accordingly to trap the customer through an appropriate and more effective route. They analyze the writing again and again to ensure the objective of writing. Moreover, they also look at the competitors to give a unique angle to the writing and make the product most popular among the competitors.

Fulfill the Company goals

The entire marketing world highlighted the importance of an effective writer. Such writers not only provide a share and same metrics but also enhance the page views and assess how long a customer stay on the company page. The effective writers actually make the way for attaining a large number of company goals, as the writing strategy is very much aligned with objectives of a company. Such strategy could help the business flourish, grow, gain customers, make money and also retain loyalty.

Hence, a good writer creates such emotive content that could inspire the customers or the readers to start following the company.

How continuous integration can help you keep pace with the Linux kernel

Almost all of Collabora's customers use the Linux kernel on their products. Often they will use the exact code as delivered by the SBC vendors and we'll work with them in other pars of their software stack. But it's becoming increasingly common for our customers to adapt the kernel sources to the specific needs of their particular products.

A very big problem most of them have is that the kernel version they based on isn't getting security updates any more because it's already several years old. And the reason why companies are shipping kernels so old is that they have been so heavily modified compared to the upstream versions, that rebasing their trees on top of newer mainline releases is so expensive that is very hard to budget and plan for it.

To avoid that, we always recommend our customers to stay close to their upstreams, which implies rebasing often on top of new releases (typically LTS releases, with long term support). For the budgeting of that work to become possible, the size of the delta between mainline and downstream sources needs to be manageable, which is why we recommend contributing back any changes that aren't strictly specific to their products.

But even for those few companies that already have processes in place for upstreaming their changes and are rebasing regularly on top of new LTS releases, keeping up with mainline can be a substantial disruption of their production schedules. This is in part because new bugs will be in the new mainline release, and new bugs will be in the downstream changes as they get applied to the new version.

Those companies that are already keeping close to their upstreams typically have advanced QA infrastructure that will detect those bugs long before production, but a long stabilization phase after every rebase can significantly slow product development.

To improve this situation and encourage more companies to keep their efforts close to upstream we at Collabora have been working for a few years already in continuous integration of FOSS components across a diverse array of hardware. The initial work was sponsored by Bosch for one of their automotive projects, and since the start of 2016 Google has been sponsoring work on continuous integration of the mainline kernel.

One of the major efforts to continuously integrate the mainline Linux kernel codebase is, which builds several configurations of different trees and submits boot jobs to several labs around the world, collating the results. This is being of great help already in detecting at a very early stage any changes that either break the builds, or prevent a specific piece of hardware from completing the boot stage.

Though can easily detect when an update to a source code repository has introduced a bug, such updates can have several dozens of new commits, and without knowing which specific commit introduced the bug, we cannot identify culprits to notify of the problem. This means that either someone needs to monitor the dashboard for problems, or email notifications are sent to the owners of the repositories who then have to manually look for suspicious commits before getting in contact with their author.

To address this limitation, Google has asked us to look into improving the existing code for automatic bisection so it can be used right away when a regression is detected, so the possible culprits are notified right away without any manual intervention.

Another area in which is currently lacking is in the coverage of the testing. Build and boot regressions are very annoying for developers because they impact negatively everybody who work in the affected configurations and hardware, but the consequences of regressions in peripheral support or other subsystems that aren't involved critically during boot can still make rebases much costlier.

At Collabora we have had a strong interest in having the DRM subsystem under continuous integration and some time ago started a R&D project for making the test suite in IGT generically useful for all the DRM drivers. IGT started out being i915-specific, but as most of the tests exercise the generic DRM ABI, they could as well test other drivers with a moderate amount of effort. Early in 2016 Google started sponsoring this work and as of today submitters of new drivers are using it to validate their code.

Another related effort has been the addition to DRM of a generic ABI for retrieving CRCs of frames from different components in the graphics pipeline, so two frames can be compared when we know that they should match. And another one is adding support to IGT for the Chamelium board, which can simulate several display connections and hotplug events.

A side-effect of having continuous integration of changes in mainline is that when downstreams are sending back changes to reduce their delta, the risk of introducing regressions is much smaller and their contributions can be accepted faster and with less effort.

We believe that improved QA of FOSS components will expand the base of companies that can benefit from involvement in development upstream and are very excited by the changes that this will bring to the industry. If you are an engineer who cares about QA and FOSS, and would like to work with us on projects such as, LAVA, IGT and Chamelium, get in touch!

Gtk+ 3.22 theme support

Just a quick thought. I'm running gtk3-3.22.0-2.fc25.x86_64. I just run Sugar, a heavy user of the Gtk+ theming system. Usually, now is when I submit a patch to port over some of the changes to the themes.

This cycle, the Gtk+ contributers had been saying that the theme api was made stable in gtk 3.20. And hell yeah - they are right. I was thinking of putting some pictures to show you just how it is exactly the same - they got perfect compatibility! But showing pictures would be a waste of bandwidth!

So just to recap - Gtk+ 3.22 is a great toolkit. Beautiful api. Wayland, X, Broadway and Win32. Idiomatic python, c, c++, javascript (somebody even posted a JSX/Gtk+ example) and of course Vala. Best of all you can just use CSS to change how everything looks.

Edit Fonts Activity

Welcome Page UX Concept

This is just an idea I had last night for improving the welcome screen UX, if it’s too much work or Dave and Yash don’t like it I understand. However, I may try to code it myself for fun if Yash doesn’t have time. :-)

My fear is that when users start the Edit Fonts activity for the first time they will be be lost and not understand what to do. Some users might not even have a basic understand of what vector drawing is or how a font is made. This welcome screen will at least give the users a basic idea about how to use the activity. Most importantly, this makes the first screen visualy interesting, interactive and fun. Many users may not continue with the activity if the first page is dull and boring.

I’m proposing that the welcome screen have 4 options, represented by icons and text, plus an editable .glyph that reads “Edit Fonts” in the Geo typeface. The Edit-Fonts logotype will be one .glyph file that is only loaded and never saved. see below:

UX concept 01

UX concept 02

I have added a Geo-Regular.ufo file to the gh-pages repo with a special “editfonts.glyph” logotype:


There are two neat things about this approach. First, it uses components we already have, the only work will be laying out the page, which Dave or I can attempt if Yash is too busy. Second, if the user never realizes that the edit fonts logotype is editable, it still functions as a logotype. A similar UX design pattern was used for the start screen of the game Super Mario 64, see below:

Continuous Integration With Travis and flake8

Last Saturday (July 9th) Eli and I met up to review the codebase, and the main issue I identified was that Travis was not set up with flake8 to test the codebase was conforming to the pep8 guidelines.

I’d filed Issue #17 for this, back at the start of the project on May 19. Yash had started to develop the [.travis.yml]( file to build a .xo bundle but hadn’t complete this just yet, so I commended out most of the code and what remained is very simple:

# this makes travis run a fast Docker container system
sudo: false
# we use python 2.7
language: python
  - "2.7"
# we need to install flake8 to use it
  - "pip install flake8"
# we check the codebase
  - "flake8 --statistics --ignore=E402 --exclude=defcon,extractor,fontTools,fontmake,robofab,ufo2ft,ufoLib,snippets ."

You can see there’s a few arguments passed that are pretty simple.

Stastics prints the number of occurences of each error, so you can fix the most common issues across the codebase first.

E402 is about the order of imports, but since we need to import gi to version later imports, we can’t adhere to that rule, so we ignore it.

We also exclude all the third party libraries, and our snippets.

Eli and I worked together on this and I finished it up on Sunday in Pull Request #65

Yash had already set up Travis configuration, at, so once this was merged, our button went green:

travis button is green

Finally I added a file that explains how to use it.

I’ll get a similar travis set up for the gh-pages branch too.

Perhaps we could also set up a git hook that runs the flake8 command on each commit…

Kartik Perisetla's Sugar Hacks

WikipediaHI: Offline Wikipedia in Hindi !!

Last week I spent some time working on WikipediaHI activity for Sugar Desktop Environment. I must say it is one of the awesome activities I have come across. The best part is that it can serve you with data in offline mode. That is even if don't have internet connection which is otherwise required to access Wikipedia online, then also your WikipediaHI activity will serve your purpose.

There are lot many developers and contributors who are working in collaborative form on such awesome stuff who continuously inspire you to take up new things and create something that can be used by others in the world. Sugar developers and contributors are epitome of such group.

I came across few of such developers, Anish Mangal and Gonzalo Odiard, two of them whose contributions are significant for Sugar. I took up the task of creating WikipediaHI using Wikipedia dump for Hindi available for free. I followed the steps specified on this page[ hosted by Gonzalo] for creating Wikipedia activity in your own language.

I will quickly explain the steps I took to create WikipediaHI:

1) Downloaded the Wikipedia dump file for Hindi:
NOTE: [ Make sure you pick the valid latest file from here :   this location will show you listing as per dates. Pick the latest dump and proceed further.]

and downloaded WikipediaBase from this link

2) Created "hi" directory for HINDI under WikipediaBase directory and moved the downloaded dump to this folder.

3) Extracted contents of this file using:
bzip2 -d hiwiki-20121225-pages-articles.xml.bz2

4) Processed the dump using page parser:

The result of this operation will generate these files:

5) Then you can include selective articles or all articles from this dump to your activity by using this command:
* Make sure you have favorites.txt and blacklist.txt filled with appropriate keywords.

Now if you want to include all articles use this command:
../tools2/ --all

6) Then proceed to create the index for these articles:

7) In order to test the index created in previous step you can use this command:

8) Next step is to expand the templates of articles :
cd ..
./tools2/ hi

9) Go back to hi directory and re-create the index :
cd hi
mv hiwiki-20121225-pages-articles.xml.processed_expanded hiwiki-20121225-pages-articles.xml.processed
../tools2/ --delete_all

10) Download the images for the articles you selected:
cd hi

if you want to download the images for pages you selected in previous step:
../tools2/ --all

11) Create files specific to language:
(a)activity/ : activity info file for you language activity
(b)activity/activity-wikipedia-lang.svg : activity icon for your language
(c) : activity file for your language
(d)static/about_lang.html : about page for wikipedia in your language.
(e)static/index_lang.html : index page for wikipedia in your language. This is the page displayed when activity is launched. So its important for you to know the articles included in the search.db ( generated when index is created) for you to create the index page.

12) Create the XO file for wikipedia in your language:
./ hi/hiwiki-20121225-pages-articles.xml

I went through the search.db file to identify the articles present in it and create the index page accordingly.
This gave me an idea to write some script that can generate index page(part or whole) to be used as home page for activity using search.db[ Stay tuned for next blog on this idea]

Here you go.. you can see WikipediaHI

On launching this, you can see the index page listing the articles you can view offline using WikipediaHI

If you want to play with WikipediaHI, you can download it : WikipediaHI-35.xo

I must thank Gonzalo for his amazing help and guidance in getting this done. I have to mention here that Wikipedia
changed its XML format in their dumps which resulted in error when I was creating the index. I took Gonzalo's help to get it resolved.
Thanks to Anish, who motivated me to pick this up and guided me to complete it.

Thanks guys !! :D

Sugar Digest 2015-08-25

Sugar Digest

1. Google Summer of Code 2015 is wrapping up. The students have been writing their final blog reports, submitting last-minute patches, and uploading their code to Google. I want to take this opportunity to thank all of our students and their mentors for all their hard work this summer. (Also, thanks once more to Google for supporting this program.) Great strides along many fronts were made. Specifically,

  • Michaël Ohayon worked on Web versions of some core activities for the Sugarizer project: Calculate, Paint (with collaboration, Record, and Memorize. He also submitted patches to Turtle Blocks to make it compatible with Sugarizer. Michaël’s blog and git repo are worth visiting. (Mentor: Lionel Laske)
  • Yash Khandelwal worked on Music Blocks AKA Mouse Music. This is a powerful, playful model for music in a block language. Yash’s blog and git repo are also worth visiting. (Mentors: Devin Ulibarri and Marnen Laibow-Koser)
  • Ishan Sharma revisited the Turtle 3D concept, rewriting it in Javascript. His results (blog, demo and git repo) are robust, scalable, and extensible. (Mentor: Walter)
  • Amit Kumar Jha worked on extensions to Turtle programming this summer. He added argument passing and return values to procedures, passing arguments to and returning values from Turtle programs so that Turtle Blocks can be used for in-line programming by all Javascript activities, and he developed a unit-test framework for Turtle Blocks JS that can be extended to all of our Javascript activities. See his blog and the master Turtle Blocks JS repo for more details. (Mentor: Walter)
  • Richa Sehgal worked on a framework to support off-line Web programming, an interactive Javascript shell. She’s submitted patches to the upstream Browse activity. Meanwhile, checkout her git repository. (Mentor: Tony Anderson)
  • Vibhor Sehgal and Utkarsh Dhawan, although not officially GSoC students, worked with Tony and Richa on a parallel project, Web Confusion, a series of programming challenges in the spirit of Turtle Confusion to encourage students. (Mentor: Tony Anderson)
  • Abhinav Anurag made some progress on a Web collaboration framework for our Javascript activities. See his blog and code. (Mentors: Martin Abente and Lionel Laske)

In the Community

2. We will be holding an election for the Sugar Labs oversight board (SLOB) at the end of the calendar year. If you are interested (or know someone who is interested) in running for a board seat (all seven seats will be open), please add an entry in the wiki. Also, whereas ballots are only available to “members”, please officially join Sugar Labs.

3. Mariah Noelle Villarreal has submitted a panel proposal, “Building Free and Open Education Communities”, to the South by Southwest Conference (SXSW). The panelpicker voting period is now open until September 4th. If you have time, please vote and share with any appropriate channels as well as a video that was created for the proposal [16].

4. Sweet: Sugar contributors Mariah Noelle Villarreal and Ruben Rodriguez got married this summer!!!

5. There were three RED (Revista de Educación a Distancia) submissions from Sugar community members:

  • Going from Bits to Atoms: Programming in Turtle Blocks JS and Personal Fabrication in Youth Maker Projects, Josh Burker
  • Visualizing Learning in Open-Ended Problem Solving in the Arts, Walter Bender and Claudia Urrea
  • Sensores Tortuga 2.0: Cómo el hardware y software abiertos pueden empoderar a las comunidades de aprendizaje (Turtle Sensors 2.0: How open hardware and software empower learning communities) by Guzmán Trinidad, Andrés Aguirre, Alan Aguiar, Tony Forster, Walter Bender, Facundo Benavides, and Federico Andrade

6. The Sugar/OLPC program in Caacupe is expanding!!!

Tech Talk

7. Peter Robinson announce quite some time ago that the Sugar on a Stick 21 Beta is now out as part of Fedora 21 Beta (Details), but I think I neglected to ever pass on the information to the Sugar community.

8. Also worth mentioning again: Ruben Rodriguez released Trisquel 7.0 released. TOAST (Trisquel with Sugar) is an official edition.

Sugar Labs

9. Please visit our planet.

PODS Game Design | Inspiring children in the Fargo-Moorhead-West Fargo area to enhance their creativity by designing video games..

PODS picking up where Sugar Labs @ NDSU left off, except:
a. they seem to be charging for classes
b. they want to reach as many kids as possible but probably aren’t focusing on under-represented populations
c. they want to “enhance creativity;” we were trying to focus on computational thinking. Ironic.
