When installing Powershell modules from the gallery, you may run into the following error, particularly on older versions of Windows (even Windows 10):

PS C:\WINDOWS\system32> Install-Module -Scope AllUsers -Name module-nameWARNING: Unable to resolve package source ''.PackageManagement\Install-Package : No match was found for the specified search criteria and module name 'module-name'. Try Get-PSRepository to see all available registered module repositories.

The most common reason for this (aside of having some other issue with internet access) is that Powershell may still be using TLS 1.0, which is no longer supported by Powershell Gallery.

On a Windows Server with GUI, you can use the traditional method of setting the display resolution but as there's no Control Panel nor Settings app on Windows Server Core, the only way is through Powershell with the Set-DisplayResolution cmdlet.

Set-DisplayResolution -Width 1024 -Height 768

The cmdlet above sets the resolution to 1024x768. It will prompt you to accept the change, if you don't want that, append -Force parameter.

To get the current display resolution, you can use the Get-DisplayResolution cmdlet.

A slow and unresponsive Steam app on Mac is a rather common issue. Symptoms are intermittent display freezing of the app, sluggish and delayed reaction to user input (i.e. clicking on items) and slow animations in the various screens. The issues may not appear straight away after starting Steam but may build up over time, causing Steam to run increasingly slower. However, the problems are only related to the Steam app, as games themselves run normally.

This is a known (but undocumented) issue with GPU acceleration, which luckily can be turned off rather easily:

With the Steam app active, in the main menu, click Steam → Preferences.

On the left, click Interface.

Look for Enable GPU a  ...

Remote Desktop Manager Mac sometimes has issues with stale cache, especially after an update. Below is a simple one-liner/script I like to use for deleting all the cache files in a Remote Desktop Manager Mac installation.

find "$HOME/Library/Application Support/com.devolutions.remotedesktopmanager" -iname "*.mcdf2" -type f -delete

Here's the direct streaming link for Aardvark Blues FM. You can use this link in your favourite streaming app (VLC, Apple Music, etc.):

A while back, most of the references on streaming sites such as Icecast were removed, leaving only the webplayer available. As I found this not to be very handy, I started looking to find the original streaming link used in the webplayer.

In order to install a fresh copy of Windows Server on a VM with the VMWare Paravirtual SCSI controller, as the driver for the PVSCSI adapter is not included in the default Windows Server ISO, you would use the built-in floppy images to make the PVSCSI driver available during the installation, avoiding the need to install using a different SCSI controller and then swap the controller after the installation of the guest OS and VMWare Tools.

To facilitate this, you would add a virtual floppy drive, connect the correct floppy image containing the PVSCSI driver, and then load the driver during the disk selection portion of the installation wizard. Unfortunately, since the deprecation of the Flas  ...

Completely hiding Quick Access from the navigation tree in File Explorer can be achieved via the registry:

  1. In the registry, navigate to HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer
  2. Create a DWORD 32-bit value named HubMode and set its value to 1.

You may need to re-logon for the changes to take effect. You can also use group policies to apply this setting in a domain.
