A broken mouse, a broken soldier and tale of rotten wires

-
It's a really funny tale. What happened was like this - my laptop's touch-pad does not work. So I use an ancient Microsoft mouse or I used to! The mouse's left button was finicky for a while. And yesterday it decided to die. 
I being the adventurous all-repair guy, decided to use a old soldier I had to rewire the mouse. I thought I could melt out the dead button and replace it with the middle click one. It's just two soldier points on the PCB. Well, after turning on the soldiering iron, it shorted out in 2 minutes. 
Hmm. I took out the screw-driver and opened it. Turns out the wires were not copper or aluminum but were probably iron!!! And were completely rotten out!! WTF!!! After cussing for two minutes, I remembered having an old laptop adapter cable which I could reuse. 
After half an hour of messing with pliers, connections and everything I managed to get the iron working again without the little light inside, because I broke the resistor connecting the light. Anyway the iron was functional and I tried to take out the buttons. Turns out this pithy soldier was not enough. But I kept trying. And after about 4-5 minutes of hassling with it, the soldiering iron just broke apart!!! Grrr!!!
Well, for me that was enough - so I just picked up the broken soldiering iron and the broken mouse and threw them in trash. I remembered to save the good old cable. Might come in handy in future. 
Going to have to get a new mouse now!

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...
