Micro USB Host Mode OTG Cable for Samsung Mobile Phones

In this blog I talk about technology world as built. Android phones are most selling smart phones all over the world. These phones and tablets are increasingly used for watching videos and listening to music. Transferring multimedia content on to your device is painful. The software tools made by phone vendors such as Samsung Kies have problems. Android MTP and Bluetooth software leaves a lot to be desired, making large transfers fail intermitingly. Developers like me use command-line MTP tools or use Android SDK's ADB program for transferring files.

For everyone I suggest buying a OTG cable that makes life easier. This cable allows you to connect USB devices to your phone and transfer files with ease. I brought this OTG cable in Hong Kong for $15 HKD (about US $2). Tested this cable with Samsung Galaxy S2 mobile phones running Android Gingerbread and Jellybean with couple of 8GB USB drives.

You might need to install a file browser like ES File Explorer File Manager app on your phone to easily navigate to attached USB device and copy files to internal memory. You can watch the video of below.

You can pick this OTG cable in your local computer store or order one from Deal Extreme (dx.com). For more other interesting Samsung phone accessories have a look at Samsung Galaxy S2 Accessories For Presentations post.

Winning Djangojet Photo Contest

Summer sun shines on the green meadow full of dandelions and the huge Djangocon circus tent. The fantastic setting of this conference had one flaw. The roar of airplanes from the nearby airport overhead.

The ever creative conference organizers announced a photography contest dubbed 'Djangojet'. The contest required us to capture the picture of Jet planes and share it on instagram with #djangojet hashtag. My photograph bagged the prize.

I took this picture with Samsung Galaxy S2 smart phone while waiting in line for lunch. It captures the people enjoying the sunny day around the Django circus and the airplane in the bright blue sky.

You don't need fancy camera to take a good picture, your smart camera phone can do the job well. The composition and the story makes a good photograph.

Efforts continue to promote Firefox Maithili

Maithili is the native language 34.7 million people in Northern India and Eastern Nepal. In college I would try to follow the friendly banter in Maithili listening for similar sounding words in Hindi. It was only later while working on computational linguistics that I truly appreciated the richness of the Maithili language.

Firefox Maithili was released last year, making it 78th language to be added to Mozilla localization. The challenge of localization does not end after translating and shipping Firefox.Today Mozilla Maithili Localization team continues their efforts to promote Firefox Maithili by organizing workshops.

Maithili is not only a language, it is also a source of rich wisdom – Mr. Ajay Kumar Jha

On 29th May 2013, Mozilla Firefox Maithili workshop was organized by community of Maithili Computer developer working under Bhasha Ghar, a group of volunteers working for small languages having less resources. Mozilla Firefox Maithili workshop was a full day workshop where the community working with Mozilla along with some experts of Maithili language sat together to discuss the issues and challenges related to Firefox Maithili.

African Network For Localization (ANLoc) Conference 2013

Traveled to Johannesburg, South Africa, to attend African Network For Localization (ANLoc)'s Terminology and Localisation in Africa and Beyond Conference earlier this year. It gave me an opportunity to learn the history of African languages in cyberspace and meet the people behind various multilingual initiatives. The conference brought together language professionals, academics and open source developers to learn about terminology development and localization platforms.

Language is the key for unlocking the potential of Africa. The African Network for Localization (ANLoc) is a non-profit that supports African language technology development. The ANLoc partners were instrumental in the numeration and standardization of 100 African languages. The ANLoc partners and sub-projects developed Unicode fonts, keyboard input systems, translation tools and terminologies for African languages. They also devised training programs for building sustainable volunteer driven localization communities.

The conference featured technical talks, break-out sessions and brainstorming sessions. There were in-depth discussions on the various facets of multilingualism in cyberspace in context to African languages, the challenges of translating computing terms in African languages, the use of machine translation methods and the development of linguistics resources such language dictionaries and terminologies. The conference organizers maintained a good balance of discussions, along with practical hands-on workshops. The size of conference made interactions easier. It was good to meet Mozilla localization contributors from over 10 African languages during this event.

ANLoc's project localized widely used open source Mozilla Firefox web browser in many African languages. The ground realities of mobilizing and sustaining communities in Africa are apparent. Finding contributors is difficult. Most contributors refrain from volunteering due to economic reasons. The overall economic development and access to digital technologies is limited to few regions in Africa. The availability of Internet has improved but the cost is still prohibitively high. I shared my community building experiences from similar resource constrained environments across the world.

Identify, Engage, Empower: Tools for Community Building

Participated in break-out sessions on developing style guides for localization and Mozilla localization processes.

The FirefoxOS localization sprint was organized as part of the event. The localizers worked in groups to translate Mozilla FirefoxOS mobile operating system using Pootle web translation platform.

Talked about Android Internationalization and adding African language fonts and keyboard support to Android. Android currently supports few major African languages: Swahili, Amharic, Zulu and Afrikaans, but more African language coverage is needed. Cheap Android devices are flooding the African market. Today, the first internet experience for many is not on a desktop computer but on mobile phones. Mobiles play a great role in accessing information and even transfering money.

The brainstorming sessions were very interesting. The problems discussed were both at an economic and social level. These problems are similar in nature to the countries where I have been working for the past few years.

The lack of availability of African local content on the internet was a major hurdle. The African diaspora spread across the world and few local governments and non profit organizations were involved in developing local language content. The tide seems to be turning now, with increasing availability of the Internet on mobile phones. Social media and user generated content is now bridging the gap.

This conference gave me a framework for my future activities in Africa. I'll be traveling to East Africa to participate in Tech4Africa Nairobi Tech Day and organize localization hackathons. Such events will help us work on Mozilla Firefox in some of the major languages and help build sustainable Mozilla communities in Africa.

Mozilla Localization Makes a Positive Social Impact

Mozilla brings power of the web into ordinary people's hands. Every day I spend countless hours working with volunteer communities around the world to translate Firefox web browser. Reading Sudheesh Singanamalla's blog post about his encounter with a farmer in rural India was such a touching experience.

A Localization journey - A Farmer's tale - A Delightful Experience

It was on my way back in a cramped out bus, travelling researching about language changes and variations within the state of Andhra Pradesh, that I sat next to a man, quite old.

Me : What do you use in the internet? How do you talk to your son?

Old man: I go to Rajat's Net Cafe nearby by house and then talk from there on Google (meant Google+)

Me : Do you know how to read English and understand which button to click and so on?

Old man : Oh, i don't know English, but i use it in Telugu. The shop guy Rajat has seen me since he was small, so after my son went to Delhi, he separately bought a Telugu keyboard so that i can be using the keyboard.

Me: Okay, but then how do you read the information on the computer screen? Isn't that in English?

Old man : (Laughs) Don't you know, there is this software something called Firefox, it is in Telugu.

Me : Really? Can you tell me how the software looks?

Old man : You should know more, you're an engineering student but if you ask i'll tell you, its a small thing like this earth picture but a small cat , orange in colour is holding it.

Me: (smiling crazily) You know how to use it in Telugu?

Old man : Yeah, its not hard, I know how to read Telugu and also know how to use mouse, so clicking gets me the job done.

Android Device Offline: Fixing ADB Connection Error

After upgrading to Android Jellybean (4.2.2) the 'adb (Android Debug Bridge)' program failed to connect my Android mobile phone. Running 'adb devices' in the terminal showed error: device offline message.

Recently Android switched to MTP (Media Transfer Protocol). Unfortunately MTP support has some issues. For now I have to resort to using 'adb' command to work with my Android mobile phone.

Digging around the Internet, I learned that Android Jellybean has a new security feature. You need to do RSA key fingerprint verification with the PC. Otherwise the Android device will be reported as offline.

How to Fix ADB Device Offline Error

Here are the steps to connect to your Android device with adb.

• Get the latest version of adb. Update using Android SDK android program: 'android update adb'


• Restart adb server with 'adb kill-server'


• Unplug and reconnect the device to a different USB port


• Repeat last two steps until you see 'Allow USB Debugging?' dialog on your android device.


• Select 'Always allow from this computer' option

Now you can talk to your Android device using the adb commands.
