Ubuntu set local time

-
After dual booting I started getting this issue. Time would be
incorrect when I switched from windows to linux or vice versa.
Cause is the OS's consider RTC to be UTC time. And switch it to local
time. And when both consider it UTC then actual time is messed up.
So I decided to have windows keep using UTC time and switched ubuntu
to local time.

1. Disable UTC and use Local Time in Ubuntu:

In previous Ubuntu editions, you can edit the config file
/etc/default/rcS to disable UTC.

In Ubuntu 16.04, open terminal (Ctrl+Alt+T) and run the command below instead:

timedatectl set-local-rtc 1 --adjust-system-clock

To check out if your system uses Local time, just run:

timedatectl

QCalendarWidget CSS Stylesheeting

-
Recently I had to implement a calendar for a TouchScreen application. I resorted to css to modify the calendar widget's appearance so that it would be more accessible. Following is the code that enabled me to get a proper calendar. calendar->setStyleSheet("QMenu { font-size:20px; width: 300px; left: 20px; }"     "QToolButton {icon-size: 48px, 48px; font: 20px; height: 70px; width: 100px; }"     "QAbstractItemView {selection-background-color: rgb(255, 174, 0);}"     "QToolButton::menu-indicator{ width: 50px;}"     "QToolButton::menu-indicator:pressed,"     "QToolButton::menu-indicator:open{ top:10px; left: 10px;}"     "QTableView { font: 30px; }"     "QSpinBox { width: 100px; font: 20px;}"     "QSpinBox::up-button { width:40px;}"     "QSpinBox::down-button { width:40px;}");

Selecting new phone plan

-
I use a Reliance Jio SIM as my one and only cellphone number. I used to have another, but I found little use for that. So I discontinued that other SIM card. It was a Vodafone SIM and I had bought it thinking I would be using it when I visit my hometown. Turns out it's not usable there. So adios. Coming back to Jio, it was working so far so good for a while. And it was quite cheap. Then they increased the fares about 4-5 months ago. And it was costing ~Rs 7 per day. This was for unlimited Jio-Jio calling, ~300minutes free to other telcos, and 1.5GB daily cellular data. Now I got home internet, so I thought to cut costs on this. The current plan goes for INR555 for 84 days. This includes 1.4GB 4G cellular data per day, 300 min calling to other telcos, and jio-jio free. That's Rs 6.6 per day. Now I'm not even using 30minutes calling per day. And due to home internet my cellular usage has gone down. So I decided to go for some other cheaper plan. This one is INR1299 for 336 da...
