[GoogleLabs] Script Converter, Scribe and Breadcrumb

Google Labs is a playground where users can play with some of the cool experiments done at Google. Once the idea / product gets stabilized, they will be graduated from the labs. Some of the products graduated from the labs include Google Maps, Google Suggest, Google Reader, etc. Script Converter, Scribe and Breadcrumb are some of the tools recently launched in the labs. Try them out today.

Script Converter

Script Converter is an awesome tool which allows you to read a text / a complete web page in a script of your choice. This does not translate the text. This will be handy if a person can speak a particular language but can not read / write in that language. For example, I can understand spoken Telugu but can not read / write Telugu scripts. If I want to read a Telugu web page, this tool will help me to view the page in English scripts. The tool can also auto-detect the scripts used on a site. Open the twitter page of @agaraadhi. Check out the same page with English script here.

Scribe

Scribe is an auto-completion tool which was launched last month. It provides text completion suggestions based on the information already typed in the document. This also helps in saving the keystrokes. Scribe is available as a Chrome extension as well and can be used as a auto-completion on all the web pages.

 Breadcrumb 

Breadcrumb is a less known tool on Google Labs which enables you to create a variety of mobile learning applications and allows you to make your application work with only few annotations to the plain text. Annotations can be used to control the flow of text in the application. It provides an interface where in you can type the text and a mobile application will be created based on the annotated text. User guide / documentation is not available yet. Some of the use cases of this tool could be 1. Help data-center technicians troubleshoot problems on the datacenter floor. 2. Decision making system for the new employees of a team 3. Alternative for flow charts. () and [] are the annotations supported so far. click on the screenshot below to know more about the syntax.

[How to] Change the DNS server of 3G connection on Android phones

This post is a continuation to my previous post on “[How to] Change DNS Server on Android phones?”. The earlier post was about changing the DNS Server when you are connected using WiFi. For a 3G connection, a different set of properties needs to be changed and the way we change them is also little different.

Method-1 [Manual]

• Your device should be rooted. Check out these instructions to root your device with a single-click.
• Download and install the latest Android SDK from here. This comes up with all the tools needed for development and testing of your application. Make sure the driver ‘ADB interface’ is installed on your machine. In most of the cases, the driver will be installed directly once you plug-in the device.
• Connect your Android device to your PC on debug mode. Enable USB debugging on your phone. Settings > Applications > Development > USB debugging.
• On your laptop, open a command prompt and enter “adb shell”.
• Use the command “getprop | grep dns” to know all the dns properties being used. This command requires BusyBox. Please install it if you have not done it earlier.
• ‘rmnet0’ is the interface name for the 3G connection. net.rmnet0.dns1 and net.rmnet0.dns2 are the properties to be changed to point to OpenDNS server. Since, these properties are changed after the connection is established, net.dns1 and net.dns2 also have to be changed.
• Execute these commands as root user: setprop net.rmnet0.dns1 208.67.222.222. setprop net.rmnet0.dns2 208.67.220.220. setprop net.dns1 208.67.222.222. setprop net.dns2 208.67.220.220
• Done. You can test if the settings are proper by visiting http://welcome.opendns.com. Remember, the settings will be applicable only for the current session.

 

Method-2 [Semi-Automated]

• If you don’t want to take the pain of connecting your device to laptop and then changing the settings, try out this method. It uses a wrapper script which executes on your phone.
• Download and install Scripting Layer for Android (SL4A). This has interpreters for executing your shell script (in fact, lots of other scripting languages also) from your phone.
• Download the wrapper script I have written from here. This wraps all the commands needed for changing the DNS server in a shell script.
• Move the script to /sdcard/sl4a/scripts/. (adb push change-dns.sh /sdcard/sl4a/scripts/.)
• For easy access, add the scripts folder to your home screen. Long press on the home screen > Folders > Scripts. Open the scripts folder and you should see the script (“change-dns.sh”) which you have copied in the above step. All the above steps are needed to be done just once.
• Click on the script to launch it. Grant the Super user permission when asked for. You just have to run this script whenever you are connecting to your mobile network.

If you know of any hook to fully-automate the process, please share it by commenting on this post.

Unix commands on Android using BusyBox

BusyBox is an utility application which executes on an embedded Linux system to provide you with a bunch of handy Unix / Linux tools. It is designed to be a small executable which makes it ideal for use with embedded devices. The application is also known as “The Swiss Army Knife” of embedded Linux. If you have a rooted Android device, this application is a must-have one. It offers some of the popular Unix tools like grep, awk, sed, etc on your Android device.

Pre-requisites

• Your device should be rooted. Check out these instructions to root your device with a single-click. Complete guide for rooting.
• Download and install the latest Android SDK from here. This comes up with all the tools needed for development and testing of your application. Make sure the driver ‘ADB interface’ is installed on your machine. In most of the cases, the driver will be installed directly once you plug-in the device.

Installation Method-1

• Connect your Android device to your PC on debug mode. Enable USB debugging on your phone. Settings > Applications > Development > USB debugging.
• Download the latest version of BusyBox binaries for ARMV6l from here. Rename it to just busybox and copy to the root folder of your SD Card.
• Download the BusyBox installation script from here. Copy the same to the root folder of your SD Card. Now, you are all set to start the installation.
• On your laptop, open a command prompt and enter “adb shell”. Get into super user mode by typing su.
• Move  to the SD card where the binary and the installation script are placed. cd /sdcard.
• Execute the installation script sh ./installbusybox.sh.
• Check if the installation is complete by issuing a grep command. “getprop | grep dns”.

Installation Method-2

• If you don’t want to take the pain of downloading the binary and then the installation script, try out this method-2. This method eliminates most of the manual steps done above.
• Download and install the application “BusyBox” from Android market. This is not the actual application rather it is an installer for the BusyBox utility.
• Open the application. It will list down some of the recent versions of BusyBox utility. Select the latest one and click on install. Allow the Super user permission when asked by the installer. That is it. You are done.
• This method is quite simpler when compared to the other one. But, the installer is problematic with some of the custom ROMs.

Check out the complete list of commands supported by BusyBox here.

Facebook Developer Garage, Hyderabad

After being successful in several cities across the globe, Facebook Developer Garage finally came to the city where Facebook India office is located - Hyderabad. The idea of the Garage is to offer attendees a great insight into Facebook Open Graph and discuss about new technical ideas. The first edition of Developer Garage was organized at Hotel Golkonda, Hyderabad and was sponsored by Facebook itself, Intel and iridiumInteractive. David Recordon and Jonathan Hsu from Facebook gave an insight into the Facebook platform and talked about some of the open source projects which Facebook is working on.

View Full Album

Highlights

• The event was kick started by Siddharth from iridiumInteractive who was also the host for the event. He talked about the evolution of social media, its need and the role of it in our life.
• David from Facebook was the next speaker. His presentation was all about Open Graph API and Social plug-ins. He started with the Facebook usage stats and the work culture at Facebook. "A lot of Facebook work starts as a hack". Then, he briefed the capabilities of the Graph API. The API has been built with the goal of making it simple and modern. Graph API supports simple authentication of OAuth 2.0. Real-time updates is another exciting thing part of the Graph API. Know more the Graph API here.
• Jonathan’s talk was focused on the technical pieces involved in Facebook. He walked us though the technical overview of the Facebook application. He introduced to us some of the open source projects contributed by Facebook. Some of the notable ones include Thrift, HipHop for PHP, Cassandra, etc. Facebook uses a wide spectrum of technology. PHP for UI. MySQL database. Apache Web Server. MemCached for caching. Varnish as HTTP accelerator. Other open source initiatives from Facebook can be found here.
• Then, it was time for the application developers to share their experiences in developing Facebook applications. Hasan from Merxius shared his experience in building Facebook application for football fans. He talked about the different monetization methods available for Facebook developers – Impression Ads, Pay per click Ads, Social Ads.
• The most exciting part of the event was catching up with Kalpana, the first Facebook India employee. Before joining Facebook, she has with Google for around six years. I have interacted with her earlier on twitter and just got the chance to catch up with her in person. She appreciated some of my scripts and gave me suggestions to improve them. She also expressed her interest in testing few other scripts that I am currently working on. Thanks for the appreciation. That will definitely boost my morale to do more. :)

Lowlights

• It looked like some of the developer sessions were planned on the fly. It would have been great had the agenda been planned in advance. Wish there were hands-on sessions as well.
• No free WiFi and poor mobile wireless signal. This has been a major hindrance for me in live tweeting / blogging.

Overall, it was a good learning experience. Came to know about some of the cool things Facebook is working on. Hoping that the events in the future get better from here on.

Web fonts on Google Docs

To make it easy for the developers to include any web font in their page, Google launched Google Font API at Google I/O May 2010. Ever since that, Google has been making use of the web fonts on its products. Fonts API has been used in the Google form templates. Now, Google Docs gets the web fonts support. Six new fonts has been added to Font API – Droid Sans, Droid Seriff, Calibri, Cambria, Consolas and Corsiva.

Web fonts on Google Docs

Google docs has been supporting only a limited set of fonts till now. The integration of Google Font API brings cool new fonts to Google Docs.  Currently, the web fonts are supported only for English. Please choose the language as “English” from File > Language > English. All the web fonts should appear in the fonts drop down (check out the screenshot). Choose the font of your liking. Another interesting thing here is that the fonts are preserved while importing a document created with MS Word 2007.

On another development, Google is working on bringing the document editing to Android and iPad. This move will bring more mobile users for Google Docs.  Currently, Google docs on mobile has only limited features and requires third party tools to edit the documents.

PC rental service for rural India

Though the PC components and the computers have  become cheaper, the digital devices have not reached all the corners of India. A report from Times of India says that about 84% of villagers are unaware of the existence of the Internet medium. To increase the PC awareness among the rural India, Indian Government has taken few nice initiatives.  To bridge the digital divide,  Indian Government has launched One laptop per child project (200$) last year and announced the low cost tablet Sakshat (35$ approx) few months back.  Another much appreciable project from the Government is the PC rental service for rural India. Kudos to the Government. Hoping that these projects are not just for political gains.

PC rental service

A pilot program to be launched by the ministry of IT & communications. Under this program, computers specially built for rural areas will be deployed in five locations, and then rented out to citizens. “The cost may vary from R 15-20 per day. This model may remove the hindrance of affordability in buying computers . We are talking to various companies like Intel, HCL Infosystems and One Laptop Per Child Project,” a senior official at ministry of IT & communications. The pilot program would cost the government about 45 lakh. “It will also remove the problem of maintenance and repair which is a common problem in many areas. Besides the person can rent it only for the time power is available,” he added. Source: The Economic Times

Sakshat

Sakshat, which is expected to be launched on Jan 11, 2011, is powered by Android. It will be available in three different screen sizes of 5-inches, 7-inches and 9-inches. Connectivity options include Wi-Fi, a USB port,  fixed Ethernet capability and a video out. The device will also have a MiniSD card slot, SIM card slot and will have an on-board storage of 2GB memory. Educational software developed at IIT will also be available on the device. Colleges all over India have already expressed interest over this device. However, the experts have expressed concerns over the quality of the device at this low cost and have said that it is practically impossible to build good devices at this cost.

[How to] Change DNS server on Android phones?

Domain Name System / Server is the one which takes care of translating the human readable domain names into machine understandable IP addresses. If you are not able to access a particular set of websites either from your laptop / phone, DNS server could be a reason for it. It happened to me recently that only few pages were getting loaded properly on my Nexus One. To fix the problem, one has to change the network configurations to use some of the popular DNS servers like Open DNS or Google’s public DNS. On Android phones, changing the DNS server is easy if you are using the static IP. You can do it from Settings > Wireless & network settings > Wi-Fi settings > Advanced (from menu) > check the ‘Use static IP’ option. After that, you will be able to change the DNS servers. However, when you are using dynamic IP (which will be the case most likely), the process is not straight forward. DNS server details will be taken from the DHCP server which assigns the IP. 

Here are the steps to be followed to change the DNS servers:

• Your device should be rooted. Check out these instructions to root your device with a single-click.
• Download and install the latest Android SDK from here. This comes up with all the tools needed for development and testing of your application. Make sure the driver ‘ADB interface’ is installed on your machine. In most of the cases, the driver will be installed directly once you plug-in the device.
• Connect your Android device to your PC on debug mode. Enable USB debugging on your phone. Settings > Applications > Development > USB debugging.
• On your laptop, open a command prompt and enter “adb shell”.
• Use the commands “getprop dhcp.eth0.dns1” and “getprop dhcp.eth0.dns2” to know the DNS servers currently being used. There are applications like ‘ipconfig’ which will give you the same details.
• To change the DNS servers, use the command “setprop <property name>”. “setprop dhcp.eth0.dns1 208.67.222.222” “setprop dhcp.eth0.dns1 208.67.222.222”. This command has to be executed as root user.
• Remember, the above step will change the DNS servers only for the current session. You will have to repeat it when you are re-connecting to the network. Read through the next section to know about how to change the DNS server automatically when you re-connect to a network.

Changing the DNS servers automatically

• Android system chooses the DNS servers using the script located at “/system/etc/dhcpcd/dhcpcd-hooks/20-dns.conf”
• By default, /system partition is mounted as read-only. Need to re-mount the same in read-write mode. Follow the instructions here to do this.
• Take a backup of the script. Download the modified version of the script from here. The modified script has two additional lines which will override the DNS server changes. The modified script uses the Google’s public DNS.
• Changes will be applied after restarting the connection / device.

Update: To change the DNS server of 3G connection, check out this article.
