How to connect ADB to remote windows server

I work on a remote desktop for development but my android device is connected to my local laptop. I wanted to be able to use ADB device in vscode on the remote desktop and connect to the device attached to my laptop.
Can i know how could I do that?
if they both connected to the same wifi, I think you can run your app using your desktop or laptop. use ADB but first enable ### usb debug ### and ### wireless debug ### second connect your physical phone where you want to connect your physical phone to for example you want to run the app using your laptop connect your phone to the laptop using usb connector, follow the command here https://www.guru99.com/adb-connect.html after that you no longer need to connect the usb wire. hope I helped

Read Battery Percentage of iPhone via WLAN

I found an app that shows the battery percentage of my iPhone in the menu bar (iBetterCharge). The iPhone is not connected via USB or Bluetooth (it is only connected to the same network as my Macbook).
My question is: How can I get this information? The device shows up in IOReg, but only because I connected my phone via Bluetooth once.
This can be done by using the unix application "libimobiledevice". I'm not sure that it works with all versions of iOS.
//install it:
brew install libimobiledevice
//list all device
idevice_id --list // list available device UDIDs. Normally, we have to plug the device at least once to get its UUID.
//get the current syslog of device that we want to check
idevicesyslog -u <device udid>
//do some text search to get the battery info
//or running ideviceinfo (I don't know if it works wirelessly)
//run 'ideviceinfo --help' to see how it works
ideviceinfo -u <device udid> --domain com.apple.mobile.battery

Hotspot is not working correctly

I have issues in using a hotspot from a laptop using the command prompt. Can anybody help me through this?
Try running

and see if hostednetwork supported is set to yes.
If it isn't, try updating your wireless card drivers

Android emulator speed with nested KVM

I am trying to run an Android emulator inside a virtual machine and would like to use KVM's nested support to speed up the emulator.
I run the emulator with emulator64-x86 -avd test -qemu -m 1024 -enable-kvm and I've made sure KVM nested support is available on both host and guest: cat /sys/module/kvm_intel/parameters/nested is "Y"
Still the emulator is slow, is there something I'm missing or a log file I can consult to see if nested support is in fact used at all?
