Error Copying File or Folder to a Chinese Server

 the error indicates: unspecified error

This ALWAYS happens when I copy a big file from outside china to a Chinese machine or server using windows remote desktop copy/paste or rdp! the file is not really big, but anything larger than say 40MB will throw the error. 

This is due to internet censorship I guess. Use vpn or zip and divide using 7zip then transfer the files using ftp, then unzip on the server side.

Google Play Store Not Removing/Deleting Credit Card

 I have had an issue: going to payments methods under my pixel's google play store to remove one does not show any 'remove' or 'delete' option. Going to 'more options' was taking me to a web page called GPay under my google account, which showed a different list of payment methods: it did not show my PayPal, now a 'deleted' credit card that I was seeing in the google play store all the time, in fact, I wanted to delete this very cc from the google play store permanently. The solution: Install the GPay App from google on your android, there you will see the exact payment methods under the google play store but with 'remove' option. It seems the web page of GPay is pointing to a different DB compared to GPay App/Google Play Store App.

I contacted google and hope they are gonna fix it.

 Bill of material desing.

AdventureWorks database contain a production.billofmaterials table.

This is used to store a hierarchy of ingredients that together form a product. Take a bike for example: it consists of many parts. Some parts are themselves consisting of parts. The part that has subparts is an assembly, while the leaves parts (without any children/sub parts) are called components in the table. Bike1 consists of say a body1 and wheels1, the wheels consist of tube1, tyre1 and rays1. The 1 here to indicate the type/id.

The same wheels1 can be used with bike2, which say consists of body1 and wheels1. 

The table mentioned stores the wheels1 tree (tube1, tyre1 and rays1) twice. Once under the bike1 and another under bike2 (duplication of bom records). This approach has got pros and cons: it duplicates data and tree maintenance and updating. Another approach is to store wheels1 tree and then refer to its root once from the tree of bike1 and another time from the bike2 tree.

Android 12 exclamation mark on mobile data internet

 pixel 4a here: after upgrading the mobile data does not work. Resetting did not work neither restarting. Here is the solution: take the same out of the device and put it again if it is a physical one (nano). This will force the carrier and phone to match their settings again.

How to fix Your DNS server might be unavailable Error in windows

This happened on my machine when two devices got the same lan ip. The windows message in my case was not precise. if you go to cmd and run: ipconfig /all

you will see that there is a '(duplicate)' string beside the lan ip. In my case the lan ip was manual. Setting it to automatic resolves the issue or you can choose another ip or you can switch off the device that has the same ip (you get this information from the router itself) then switch it on and it gets a different ip. Glad I caught the issue in half an hour and solved it, it was very disappointing.
