Making home wifi safer

-
I saw a warning popup on my windows laptop regarding "security issue with wifi network". I clicked on the popup and it took me to a page where it informed me that the home wifi is using TKIP cypher for security and it's obsolete. I should use AES.
I opened my router's configuration page and checked in wireless settings. Found out that by default the router supports both WPA1 and WPA2. And as with WPA1 TKIP cypher is used.
This is not good. So I set it to explicitly use AES with WPA2 support. Now the warning is gone.
But my wifi router is dual band - so I have 2 SSID's with one for 2.4GHz and other for 5GHz. This change I have made is to 5GHz band. Now all other older devices connect to the 2.4GHz band. So I have a big exercise there to see if I can shift to AES/WPA2 on 2.4GHz band too.
I don't think that will be possible with all these 3-4 year old other laptops and phones. But lets see. The more secure things are the better things are!!

On other hand, I also looked at WPA Enterprise, which is even better than WPA Personal. BTW these WPA1/2 I was talking about belong to WPA Personal. With WPA Enterprise though I need a RADIUS server, which could store all the user records, then these users credentials shall be authenticated with the help of this RADIUS server, and it will be much more difficult to hack. Not really sure if it will be or not but surely should be more difficult, than a single common password.
Though this looks a bit complex to setup and maintain. And with not a lot of time available at hand, I decided to not do it. Current settings are enough, till someone comes and burns down the house.
Cheers!!

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...
