UoM WiFi worked fine with my Android

All i had to do was to connect to the uomstudent network and i fill it with my WiFi username and password. And it connected just like iPhones and iPods do 🙂

I will therefore NOT get Orange’s sucky internet plan nor switch to Emtel or Chili.

Long live WiFi at UoM 😀

Results: How much data Android eats on standby

I had made an experiment to estimate how much data Android consumes on idle. The results are now out!

I lent my sister the phone today as she needed it for school. So i took the reading earlier at 07:30.

So, for 8hrs and 30 mins, my money went from Rs 22.20 to Rs 20.84 i.e. Rs 1.36 (453KB)

Here’s the extrapolated costs:-
1 hr: Rs 0.16 (53KB)
1 day: Rs 3.84 (1MB)
1 week: Rs 26.88 (9MB)
1 month: Rs 107.52 (35MB)

Assumptions:-
– You will be out all the time.
When you are at home, you would be connected to WiFi therefore it won’t be reflected on your bill
– No browsing or other manual Internet tasks were carried out.
In real life, you’ll be browsing the net occasionally, checking Facebook, reading emails etc.

Conclusion:-
It is a very bad idea to let your Android Internet on while you are out. It is recommended to deactivate data network whenever you don’t need it.

My First Qt App ft. Linux Notifications

This is more than just a “Hello World” app. It uses the linux notification API to send global notifications.

It is very easy to do this. It’s like working in Visual Basics.
– Create a button in the ui editor.
– Right-click on it then select “Go to slot”
– Select signal “clicked()”

For following code will be created in mainwindow.cpp

void MainWindow::on_pushButton_clicked()
{
}

Now you can add the notify function between the curly brackets

system("kdialog --title '*le Nayar testing' --passivepopup \"Hahaha, i still don't know how to fetch the text above :P\"");

You can alternatively use libnotify instead of kdialog. libnotify works in both GNOME and KDE.

system("notify-send '*le Nayar testing' \"Hahaha, i still don't know how to fetch the text above :P\"");

Now i need to put some variables instead of hardcoding texts and play with the options provided by kdialog and libnotify 😉
