Cannot run Python application after installing using pip
I was trying to install qark, an android security program, through pip.
After installation, the readme say to run qark –help. However the system cannot find this command.
After trying python -m quark.py, python quark.py, etc with no result. I managed to solve by finding out that the Script folder of the Python installation contains the .exe file for qark, qark.exe.
Adding this folder to my PATH environment variable allows running this command in the command prompt.
This should be something to be mentioned in the readme at least.

Model properties are all null after retrieving from POST request.

Web Service Host for WCF doesn’t work
If you open a WCF Solution that uses a web site to host the WCF services and the services cannot be browsed when opening using a web browser (showing HTTP error 403.1 not found), try turning on HTTP Activation feature.
On Windows server, go through server manager.
On Windows desktop, search for turn Windows features on or off, Under .NET Framework Advanced Services -> WCF Services -> HTTP Activation. Check HTTP Activation to enable it, and click OK.
This really wasn’t apparent at first and I thought there was some issues with the config files.
Unity game shows purple screen on older Android device, “your device doesn’t meet minimum requirements…”
Go to Build Settings -> Player Settings -> Other settings -> Rendering.
Set Auto Graphics API to true. On some older devices there wouldn’t be Vulkan API and the game wouldn’t work.
Android Device not showing in Chrome Developer Tools under remote devices
If it doesn’t show, it’s possible that it’s because the adb daemon is not running to detect plugged in devices or emulators.
Run adb devices in a terminal to start the daemon if not running already.
Make sure USB debugging is enabled in the device.
Make sure the Android USB driver for the device is installed in the computer.
Cannot find Certificate when configuring IIS bindings
When configuring bindings, IIS list certificates in the personal store.
So when generating a certificate using Powershell or Openssl, make sure the cert is in the Personal store. Then it will show up when configuring SSL bindings in IIS manager.
In order for the browsers to trust the cert, install self-signed certs to the trusted root CA store. But don’t remove it from Personal store, because it’s needed for bindings.
