Google's Project Ara Highlights



Project Ara is Google's Modular Phone System.

The purpose of Project Ara is to create a modular smartphone that would allow users to swap hardware components according to their own wish. It will help the users to create their own phone by choosing the modules of their choice.

I came to know about Project Ara when Motorola announced about it on October 2013.

I created this video to give news about Project Ara on that day. From the comments made for this video, I came to know that the modular phone concept was already popular among many people as the Dave Hakkens's Phonebloks video went viral.
From that day onwards, I am continuously looking for the news/details about modular phone system especially about Project Ara, and published various news articles about project ara. And, I have created a facebook group to discuss about project ara as I found that many people are actively participating in the discussion about project ara by making comments in this video.

Today (January 14, 2015) Google is conducting second project ara Developers conference. You can watch the live steam here. Google is broadcasting live from Mountain View, CA on January 14, 2015 beginning at 8:00AM PST. If you are not having enough patience to watch the entire event, you can subscribe to our channel to see the highlights of this event later.


The ara platform will include a structural frame/endoskeleton that holds smartphone modules of the owner's choice, such as a display, camera or an extra battery. It would allow users to swap out malfunctioning modules or upgrade individual modules as innovations emerge, providing longer lifetime cycles for the handset, and potentially reducing electronic waste.

Google says the phone is designed to be used by "six billion people", including the one billion smartphone users and the five billion feature phone users.

Watch the below videos to know more details about Project Ara.






Since I am continuously monitoring new details about Project Ara, I think my understanding about the growth of project ara will be correct to some extent.

I am listing my understandings about Google project ara.

- Lot of people (mostly developers) are showing interest to know about Modular phone system. But many of them think that effective modular phone system is NOT feasible.

- Developers believe that Google can make the project ara successful. So, they are showing very much interest in attending dev conference, getting ara dev boards, and discussing about project ara in various social media sites and forums. Even some big companies are showing interest to develop modules for project ara as they believe they can target their modules to billions of people once project ara getting popular.

- As of now competition for Project ara is very low. Few companies such as vsenn and Puzzlephone are trying modular phone system in very limited ways.

- Right now, Common people are not showing much interest to know/discuss about project ara. They may show interest once Google starts promoting Project Ara.

- Hardware industry also started taking steps to produce hardware supporting project ara.

- When Modular phone system was just a concept, many people thought it is NOT possible to have modular phone. But they gained some confidence after Google started taking solid steps to bring it as reality, especially when it showed the prototype at Google I/O.

- Many people prefer to buy new set of phone than replacing the repaired parts. That kind of people are not showing interest for project ara.

- Release date for project ara is getting delayed.

Work around for solving round off issues when converting existing MySql Column from FLOAT to DOUBLE



Today I have noticed a strange behaviour of mysql database when I tried to convert mysql column type from FLOAT to DOUBLE.

I had a MySql table "employee_project_rates" with a column "basic_hourly_rate" of FLOAT datatype. All the existing records of this table were having values with two decimal places. I wanted to add a new record having a value with more than 10 decimal places. I couldn't do it as the FLOAT datatype won't allow this much decimal places.
So, I had decided to convert the datatype from FLOAT to DOUBLE.

After making this datatype change, I have noticed that basic_hourly_rate value in all the existing records were automatically changed to value with many decimal places. The decimal values beyond the 2 digits are having some random numbers.

I couldn't understand why this kind of change occurs. If you know the reason behind this kind of change, you can share your thoughts through the comments.

Anyway, this change is not acceptable as it had changed the values of existing records.

I came to know that the only way to handle this issue is, we have to solve this issue by adding new column with desired datatype and then adding the values again to the new column.

So, I tried below query after adding a new column basic_hourly_rate_double.

update `employee_project_rates` set basic_hourly_rate_double= basic_hourly_rate

But this approach is not useful, as the values in basic_hourly_rate_double are NOT same as the values in basic_hourly_rate. basic_hourly_rate_double was having many decimal values with random numbers.

So, I used below query to address this issue.

update `employee_project_rates` set basic_hourly_rate_double=ROUND(basic_hourly_rate,2)

After running this query I deleted the basic_hourly_rate column and then renamed basic_hourly_rate_double to basic_hourly_rate.

The approach solved all the issues. Now basic_hourly_rate column of existing records were having unchanged data (i-e values with 2 decimal places) and I can add any new record with values having many decimal places.

Using both "sum" and "limit" in a mysql query



Recently I wanted to use both "limit" and "sum" in mysql query.
"Sum" will return single value while "limit" is for returning multiple records.
So, the below query did't work.

select sum(price) as total_price from transactions ORDER by transactiondate DESC limit 50,10

Anyway, I needed this kind of query to get sum of price from all the records starting from 51 to 60 in a pagination script.

I had to redefine the query as below to make it work.

select sum(price) as total_price from ( select price from transactions ORDER by transactiondate DESC limit 50,10 ) as prices
