How to Remove Proxmox “No Valid Subscription” Errors

Every time you log in to Proxmox or update it, there’s an error that pops up telling you that you haven’t purchased an enterprise license key. If you are using Proxmox in an enterprise environment, I would recommend buying a license (even though it’s not required). You’ll get access to an enterprise repository that contains stable security and software updates. But if you run Proxmox non-commercially and want to remove the no subscription error messages, follow the instructions below.

How to Add A Windows Partition to GRUB

A while ago, I installed Linux on my laptop along with Windows. I used GRUB instead of the Windows Boot Manager to switch between both installs. However, when Linux updates GRUB, it won’t detect the Windows partition and as a result, won’t add it to the GRUB boot menu list. So to fix this, we’ll need to install OS Prober.

Dual Boot Windows & Linux with Encrypted Hard Drive

I recently started moving away from closed source software like Windows and Google products. One of my latest projects is to move away from Windows OS as much as possible. However, since I have a Surface device, Ubuntu doesn’t come with all of the drivers. The main issues I encountered were that the touch screen doesn’t work and the WiFi doesn’t come back after the system is suspended.

How to Access a Active Directory Network Share on a Non-Domain Joined PC

Sometimes you need to access a network share that requires an active directory authentication, but, you’re on a PC that’s not part of the domain. Saving the script below as a .bat file and replacing the parts that say “Server” with the actual name or IP of your server will allow your PC to access any network share with active directory credentials. Mostly, this is useful when you only need temporary access to a share, but don’t want to go through the whole network share mounting process.
