OpenStreetMap – Wikipedia for maps
June 14, 2015 by ·
OpenStreetMap is a website for collaborative mapping. I just signed up and spent about an hour editing the map nearby my apartment and workplaces. It was so much fun. Added a bunch of bus stops, library, grocery supermarkets and banks. Its good that we have an alternative to Google map and it belongs to no one and everyone.

Google play store update not receiving for alpha or beta tester
December 16, 2014 by ·
If your testers are not receiving the update option for alpha or beta testing, try the following
- Make sure you followed Google’s instruction correctly. That is, a) Create google group b) Add the tester to the group c) Make sure tester accepts to be a tester
- If your tester has several Google accounts in his/her phone, then either add all these accounts as testers or remove non tester accounts from the phone. ‘Application already exists’ notification error shows up if you have any non testing Google account in the device. It is just best to have only one Google account in the device which is the testing account.

May 4, 2014 by ·
Download “Capital City to Country Quiz”
Just about a couple of weeks ago, I released a free android app called ‘Capital City to Country Quiz’. There are a bunch similar apps in the Google Play Store. The main difference at the time of this writing about my quiz app is that the quiz is set opposite. Most of the capital cities app shows country name to player and the player has to guess the capital city. In the app I created, it shows the capital name and the player has to guess the country. There are few reasons why this is more fun compare to the former.

January 14, 2014 by ·
This code will compile and run. Notice the assignment operator(=) in the condition.
boolean a;
boolean b = true;
if(a=b){
//do anything;
//this compiles
}
But this won’t compile
int a;
int b = 5;
if(a=b){
//notice its still = not ==
//do anything;
//this does not compile
}
The reason is because the previous code’s a is of
booleantype and the latter’s is of
inttype.
ifstatement is not necessarily followed by a condition.
a=bis not a condition. Its an assignment. But it works if the left variable (i.e. a) is of a boolean type.
So its better if we think
if(boolean)instead of
if(condition). Anyway, a condition like
a==b or a>b etc will result a boolean result.
Toronto 2013 Blackout shelter places on Google map
December 23, 2013 by ·
About 200,000 or more Torontonians are suffering blackout right now.(December 23, 2013). I am writing this in candle light with a little bit of battery left on my phone and laptop by using tethering the internet of my phone to the laptop.
If you are on the road in this freezing weather and need to find a closest shelter, check this map I created on google map. The list is as per emailed to me by the toronto city’s newsletter. I may not be able to update when the list changes in future, so please after finding the location on the map. Call them to verify.
