Google Reunion in Silicon Valley with FOSSASIA

Being at the get together of more than 500 mentors and students of over 200 projects from 50 countries at the 10th anniversary of Google Summer of Code and join the celebrations at the Reunion 2014 is an amazing experience. It was the first time that Google brought together such a large number of contributors in Silicon Valley for a fantastic Unconference, a great day out at the “Great America” and a Gala at the San Jose Tech Museum with Linus Torvalds and a catering with an outstanding American Fusion cuisine.

Google Mentor Summit Tshirts

Yes, 10 years! Google Summer of Code is the only program of a company supporting hundreds of Open Source projects for many years and bringing them together with students from around the world. The magnitude of this support shows the real commitment of Google to Free and Open Source Software and I would like to thank everyone involved including Carol Smith, Cat Allman and Stephanie Taylor, and all the other fantastic people at the Open Source office supporting us.

The idea of free sharing and collaboration across borders has always inspired me. And I could not be happier to enter the conference room in San Jose – full of creators, developers, contributors of many amazing Open Source projects such as Mozilla, KDE, Python, Haiku, Blender, GNU, Debian, Inkscape and many more.

Google Reunion 2014 in San Jose with FOSSASIA

In previous years, the program brought together mentors of each active organization, but for this years celebration Google also flew in mentors of former years and even some students of the program. As an organizer of our annual FOSSASIA event I know what a challenge it can be to bring in a few dozen speakers from different parts of the world, but flying in 500 Open Source contributors from around the world is a logistic masterpiece. Organizing this event takes a huge amount effort and resources. Two thumbs up for the organizing team, they did an amazing job. I am grateful to be among the participants.

Great Day Out at the Great America

Every year the Mentor Summit spreads out in two days filled with interesting unconference sessions, lighting talks, and plenty of spaces for group discussing and code sprints. This time Carol and the team went an extra mile to surprise participants with an additional day-out at the Great America Theme Park (exclusively for us!). Believe it or not the majority of my lovely geek friends apparently have never been to an amusement park in their lives. We had such a great morning and afternoon there. I am sure some of us will never forget that very first roller coaster ride. It is great that Google makes this experience possible for mentors and appreciates their contributions.

Gala at the Tech Museum San Jose with Linus Torvalds

Another of the highlights of this year was the Gala at the Tech Museum in San Jose. Everyone dressed up in beautiful garments. It was fun to see all the developers who kind of always wear black shirts suddenly dressed up. And, on top of organizing everything the team also arranged a meetup with a star of the Free and Open Source community: Linus Torvalds joined us as a special guest. Of course Linus was everyones hero. And I was thrilled to meet him and Dirk Hohndel just before their talk. Sincerely thanks to Cat Allman for introducing him. I took the chance to invite them to our next FOSSASIA in Singapore, which will take place from March 13-15, 2015.

Linus Torvalds FOSSASIA Meetup at Google Reunion with Hong Phuc Dang, Dirk Hohndel, Mario Behling

After the interesting talks about the history of Linux, Open Source at Google and future projects, we experienced the interactive exhibits at the Tech Museum and enjoyed more of the yummy food. Coming from Asia, experiencing the food in the US is always very special for me. Especially in Silicon Valley and San Francisco I love the Fusion food, the blend of Western food and Asian cuisine. On the night of the party, the Google team really did arrange a fantastic catering with very friendly caterers, who knew a lot about all the different ingredients. I learned from Stephanie that this was one of the best catering companies and that they came all the way from San Francisco. It was truly special indeed.

Participants at the Reunion

Personally I was so excited to meet with the developer team of Processing at the Google Reunion. Processing is one of my favorite software applications. One team member – Andres Colubri from Argentina – told me he finally met his friend and co-developer whom he worked together with during the last 7 years but never got a chance to meet.

Some voices of participants of this years summit: Doris Lee, a first year GSoC from Taiwan said: ”The program is a great way to practice and apply what I have learned in programming. I took computer science at UC Berkeley but I never had the feeling I get the right assignments to work on. I enjoyed so much to work with GSoC program which gives me a chance to improve my coding skill, to learn how to use Git, Python and much more.”

Adnan Zahid – 2nd year GSoC student also commented: “It is good that Google created the program for public benefits and I wish this program can be extended not only during summer but throughout the entire year. My suggestion is to create cooperation between Open Source projects and universities so that the schools constantly receive assignments and then distribute them to students”

Hamish Bowman from OSGeo said: “We are participating at GSoC for many years and I am happy to see new and old faces at the Reunion. For me the mentor summit is a chance to meet developers from projects, that we are using and working together with. Many of them, we would not be able to meet some anywhere else. After a long time, I had the chance to talk again with Mario Behling who is working with lots of projects and founded Lubuntu. It was great to see Mario’s excitement when I showed him our OSGeo Live distro which we build on top of Lubuntu.”

Google Reunion Hamish Bowman and Mario Behling Lubuntu Founder

I also spoke with one of the most senior mentors – Kevin Krammer from KDE, it was Kevin’s 10th time mentoring. He said: “This is a fantastic thing. I appreciate the opportunity to be mentor. I think we had very good students who have helped KDE a lot during the past few years. GSoC gives us the possibility to experiment new things for which we normally do not have enough resources and this is a great training opportunity as well.”

 

The closure Q&A session marked another year of GSoC was over. We are all looking forward to another 10, 20, 30 …years to come. Once again congratulations to GSoC 10th Anniversary!

UNESCO Youth Mobile Workshop in Paris with FOSSASIA

The 1st YouthMobile Experts Meeting took place at the UNESCO headquarters on 19th and 20th March 2014 with participation of FOSSASIA. UNESCO has conducted a global search for the best, existing mobile applications training initiatives with openly-licensed training materials, and invited a selected group of training providers and app development tools makers.

Objectives of the Meeting:
1. Facilitate the sharing of best-practices between the training providers; and
2. Further select the best providers to enter into partnerships for up-scaling and integration into teaching and learning environments.

I had the chance to meet David Ascher and Geoffrey MacDougall from Mozilla and Bobby Richter the developer of Mozilla Appmaker. Andrew F. Mckinney is the manager and developer of MIT App Inventor.

The UNESCO seeks to extensively promote very high-quality, multi-lingual, comprehensive training materials for developing mobile apps. Openly-licensed, the training materials identified will allow for adaptations including translation, localization, and innovations. The YouthMobile experts meeting is part of UNESCO’s contribution to the 2014 celebrations for Open Education Week.

GSoC Ideas 2014

FOSSASIA aims to participate in the Google Summer of Code 2014. We are working together with a number of Open Source developers in the region and function as an umbrella for different projects. If FOSSASIA gets accepted, you will find more information about the application procedure for students on this page.

The ideas list below gets updated continuously as students also submit ideas in the process. So, please check back again later. If you have your own idea or small project, please apply for FOSSASIA on the Google Summer of Code website!

If you have questions or feedback, please write to us on the mailing list: http://groups.google.com/group/fossasia

We have four areas for our GSoC projects 2014:

 


Open Design Projects, Garments, Knitting


 

Develop 2D Body Measurement App

The goal of this project is to provide users with an Android app that assists them in measuring their body data for generating customized patterns. The measurements are taken according to standardized measure points which are usually used by tailors. The student needs to propose a design and step by step guide to collect the measurements of the user. The data will be saved to the app or as a file, with additional options to export data as a Google spreadsheet and submit data to a web service.

A draft of a file format has been developed. A sample part below:

Develop a GUI for the Adafruit Knitting Machine Project

The goal of this student project is to facilitate the production process with the Brother KH-930e Knitting Machine, that can be controlled by Open Source software as below. Parts of the process require commandline experience and Python knowledge. In order to enable more knitting enthusiasts to use Open Source knitting machines, we hope to find a student that takes on the challenge and comes up with ideas to make this process easier. Below a video of the current work process and step by step descriptions.

 

Disk Drive/Computer Connection Notes

The external floppy drive for this machine was the same as a Tandy PDD1 (Portable Disk Drive 1). This drive is connected using a serial port. There is documentation on the internet about how to connect these drives to computers, but the connector pinout on the knitting machine is different than the drive, and I didn’t find that documentation to be helpful. I was able to figure out the connector pinout by examining the knitting machine PCB.

Knitting Machine/Computer Connection Notes

The knitting machine drive connection uses CMOS voltage levels, not RS-232. Here is the pinout of the drive connector on the knitting machine:

      _____
      |   |
______|___|______
|   |   |   |   |
| 7 | 5 | 3 | 1 |
|___|___|___|___|
|   |   |   |   |
| 8 | 6 | 4 | 2 |
|___|___|___|___|

The pin numbering is shown as they are labeled on the knitting machine PCB, and does not agree with other documents I found on the web.

Connector Pinout
Pin Signal I/O Notes
1 Ground    
2   Out Tied to 5, Pulled up through 1K resistor
3 CTS? In (Tie to pin 2)
4 No Connection    
5   Out Tied to 2, Pulled up through 1K resistor
6 RXD In  
7 TXD Out  
8 RTS? Out Follows state of Pin 3 (buffered)

Methods of connecting the knitting machine to a computer

Using a FTDI serial adapter cable (RECOMMENDED)

Using an FTDI adapter is the best way to assure that you are interfacing with the machine using the same signal voltages as the original external floppy drives. This is documented on this wiki page, which will someday be merged with this one.MProg only runs under windows.

Using a USB serial adapter WITH flow control

This is a method I have used extensively with one model of knitting machine, but I no longer recommend it. Although it does not require any additional hardware like a FTDI adapter, this method does not present the exact same voltage levels to the knitting machine as the external drives which were designed to work with the machine. Although I have not had any reports of problems, it is possible that this method could stress the knitting machine input circuitry, and therefore I think it is safest not to use it.

Using a USB serial adapter WITHOUT flow control

I have pulled pin 3 high, and am not using flow control in my software. I have not had problems with data loss while sending to the knitting machine, and the machine I am using is fast enough to always keep up with data received from the knitting machine. The data rate is 9600 bps, and the largest amount of data sent at once is 1024 bytes. Here is the cable I am using to connect the knitter with a USB 9 pin serial port:

Software Interface Information

There are a number of documents on the web about the Tandy PDD1 and the serial API for it, Most of them are incomplete. The knitter places the drive into a mode called “FDC emulation Mode”, which allows access to raw sectors. This document is the most complete documentation I was able to find: Media:Tandy-Disk-Reference.pdf

External Disk Drive Emulator

I have written software that emulates the external disk. It runs under Linux and keeps the data as files on the linux file system. This allows knitting designs to be saved and restored using the emulation computer. I am using these files to reverse-engineer the knitting machine file format. The emulator is written in Python, and released under the GPL. It has been tested most extensively under Ubuntu Linux. I have reports that it does not work on windows due to problems with the serial library. It has been successfully run under OSX. If you have any information to add about platforms that it does or doesn’t work on, let me know and I will update this informationI am happy to work with people who are trying to use the emulator with different models of knitting machine, and hoep to improve compatibility with other machines. The source code is available in the git repository listed above. Software for manipulating Brother data file: I have begun a python class which will provide an API to the brother data files. Source code is in the git repo. Knitting Machine File Format: A lot of the file format is now understood. Documentation is in the git repo.Work on this continues.This work was greatly helped by prior work performed by John R. Hogerhuis and posted on the kminternals yahoo group.

Create search functions and import pattern functions for Valentina

Valentina is a development project to edit pattern files for garments and textiles. The goal of the student project is to implement a method to choose additional design items, e.g. different collar styles, and to add them into a pattern during development.  In addition, the user should have the capability to organize their created patterns into categories, and conduct searches of patterns based on this organization. 

The student would develop user functions to add search tags to patterns, search for patterns, and select patterns from search results to load into the currently open pattern.

Background: One of the main ideas of Valentina is to enable users to create custom sized patterns based on applying an individual’s measurement data to pattern formulas, independent of industry sizing standards. Similar industry software packages include Assyst (www.assyst-intl.com), Lektra (www.lectra.com), Grafis (http://www.grafis.com), plus others. Grafis in particular enables users to generate patterns based on formulas derived from pattern descriptions from standard books (e.g. books published by Mueller und Sohn.) Currently available industry software, however, does not aim at the DIY/maker or SME markets.

Project: Valentina Patternmaking Project

Website: http://www.valentina-project.org

Skill Level: Medium

Usefull skills: Vector graphics, C++, Qt5, basic knowledge of garment patterns, basic knowledge of generating patterns from formulas

Mentors: Hong Phuc Dang to be announced

 


 

Port Valentina to different platforms, build packages and refactor code

Currently the installation process of Valentina is only semi-automatic on Linux and Windows. For MacOSX there is no port yet available. The goal of this project is to automate the build process for the major operating systems. Create a standard workflow for Windows .exe builds, create a MacOSX port and provide packages for the major Linux distributions. The challenge of this project is to work with a number of projects and partners. For example, it is possible to create .deb packages for Debian. In order to get the package accepted in the Debian repository, it is necessary to get approval of established Debian developers who verify that the package build was done according to best practices. Similar procedures are required for other distributions. The second part of this project is to refactor code and replace deprecated code including if constructions with switch. Please see below.

Many if constructions replace with switch.

Methods:

VDomDocument::ParsePointElement
VDomDocument::ParseSplineElement
VDomDocument::ParseArcElement
VDomDocument::ParseToolsElement

For example:

QStringList arcs;
arcs
<< VToolArc::ToolType << VNodeArc::ToolType;

switch(arcs.indexOf(type)){
case 0:
// parse arc tag
break;

case 1;
// parse node arc tag
break;

default:
// print warning
break;
}

Project: https://bitbucket.org/dismine/valentina/overview

Add Design items and Measurement Tables for Patternshare

Patternshare is a development project of a web application to edit pattern files for garments and textiles. The goal of the student project is to implement the choice of additional design items, e.g. different collar styles, and to add them to the patterns. Patternshare users should be able to generate non-custom sizes on the fly and add their own measurements table in the app. Another required feature is to add specific design items or changes, e.g. starting from size 36 up to 42. In order to establish a suitable way to allow the sharing of patterns in an industry quality, patternshare needs to support these features and be able to import and export CAD files.

Background: One of the main ideas of patternshare is to offer a web service that enables people to edit patterns independently from standard sizes. Similar industry software packages including Assyst (www.assyst-intl.com), Lektra (www.lectra.com), Grafis (http://www.grafis.com) and other exist. Grafis in particular seems to generate patterns in the same way, that we do it in patternshare – based on formulars which are defined from pattern descriptions from standard books. Many standards defined in books from Mueller und Sohn for example. The current players do not aim at the maker and SME market.

Web and Mobile Development


Implement Post to Github in NGO photo app and develop a Jekyll/Markdown Website

The goal of this GsoC project is to develop functions, that allow users of the phimpme photo app to upload images to their gallery that uses Jekyll, Javascript and Markdown. The most well-known one sites using these technologies are github pages. The phimpme photo app connects to “any social service” and Open Source CMS. It was developed for development projects in South East Asia and Open Sourced recently. Phimpme is a beautiful photo app that already works with any web systems based on Drupal, Joomla and WordPress. Android and iOS versions exist.

Anonymous mode and autosharing for phimpme Android app

Implement an anonymous photo sharing mode with auto-connect options to nearby phone , computers and wifi nodes with public sharing capability. Bluetooth connectivity was already implemented in the app to support this future feature. The implementation of Wi-Fi direct would require to change the minimum required version for Android to version 4.1 (Jellybean). Some functions and libraries that are required for this project are already implemented partly for other services. The goal of this project is also to use existing libraries and extend or change them where necessary to keep the code base clean and small. To make full use of an anonymous sharing mode as many systems as possible should be supported, e.g. shared folders on PCs, public ftp and other phones. The requirements include that sharing works without an Internet connection (local networks without Internet and other devices are available to connect). At the beginning of the project we require the student to define a list of features he/she plans to develop during GSoC and a timeline.

Network and Mesh Technologies

 

Develop Web Interface Administration tool for large numbers of Nodes (routers) for OpenWrt based on kalua

Kalua is a hardware-independent OpenWRT-extension (using busybox-ash as main-language) for setting up, monitore and manage many, large wifi-mesh-networks for different locations including billing, captive portal / splash screen / weblogin, accounting, data retention and layer7/8-QoS. OpenWrt is a widely used Linux distribution for embedded devices and specifically routers. Large networks consist of hundreds and even thousand of nodes. Administration of routers, e.g. ESSID setting is a long process.

The goal of the project is to develop a new web interface to show the status of routers and enable mass administration of devices.

FOSSASIA is Mentor Organization for Google Summer of Code 2014

FOSSASIA participates again as a mentor organization in Google Summer of Code 2014. Students can apply for scholarships of FOSSASIA on the Google Melange website. Accepted projects will be published on the site here.

Google Summer of Code is a program that offers student developers stipends to write code for various open source projects.  Historically, the program has brought together over 7,500 students with over 440 open source projects, to create over 50 millions of lines of code. The program, which kicked off in 2005, is now in its tenth year. If you are feeling nostalgic or are interested in learning more about the projects we have worked with in the past, check out the 2006, 2007, 2008, 2009, 2010, 2011, 2012, and 2013 program pages (https://www.google-melange.com/gsoc/document/show/gsoc_program/google/gsoc2014/help_page)
