core isolation::Memory Integrity causing virtualization to fail on Windows 10

-
Recently I wanted to install bluestacks to check out some apps temporarily. I have windows 10 - fully updated and with hypervisor support and virtualization support in this new laptop on Ryzen 5.
Checked out few options about installing virtual machine support etc windows components, since I have Windows Home and not Professional. But no success, so I gave up for lack of time. Just used my cellphone to check out the apps.
Next time - few days later I needed to create a Ubuntu VM to test some VNC/RDP software, and VirtualBox also would not work.
I checked few more links etc. Some of them asked to install the same windows components related to hypervisor support and virtual machine. These are already there. And they also asked to disable Memory Integrity settings in core isolation settings in Security portion of Windows Settings.
Now after disabling Memory Integrity, Virtual Box started fine.
I thought maybe this was the real culprit for Bluestacks not working. So installed it again. And lo behold! Even bluestacks also worked fine now.
So if any of you having this same issue, do check out Memory Integrity setting. It's good to have it enabled if you don't use any VM's and stuff. But disable it if you want to use virtualization for anything.
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...
