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

https://streaming.live365.com/b77280_128mp3

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.

Dell OS10 (used on PowerSwitch S-series) supports RDMA over Converged Ethernet (RoCE). The SmartFabric manual has some good examples on how to configure it but here's the summary.

A few remarks first: you can choose which queue to place traffic in. The manual states Q3 which is the required queue if you also use iSCSI (which is by default placed in Q4), but if you don't use iSCSI, you can opt to place the traffic in Q4 instead of Q3.

Also, when entering the commands, be sure to check whether you're in the proper context in CONFIG mode. I did not add the necessary "exit" commands so don't blindly copy/paste this.

First, enable DCB(X), which is required for RoCE (PFC and ETS):

It is possible to automatically bring up a network interface without any IP address configuration in Debian. This can be useful for e.g. traffic flow monitoring where the interface is subsequently placed in promiscuous mode by software such as tcpdump.

Like always, all network interface configuration is stored in the file /etc/network/interfaces. For the interface you want to bring up without an IP address, add these lines:

iface eth0 inet manualpre-up ifconfig $IFACE uppost-down ifconfig $IFACE down

If the interface is a VLAN interface, the up/down commands must be executed after/before the VLAN hooks, so it should then read:

iface eth0.2 inet manualpost-up ifconfig $IFACE uppre-down if  ...

Here's a list of direct download links to the latest macOS installers. They are all links to Apple's servers, either direct links to the App Store, or, in case of older versions, links to Apple's CDN.

Direct links to App Store:

Older versions are only available as DMG files from Apple's CDN:

If you need to perform packet captures on virtualized appliances, it can be useful to get a statically linked binary of "tcpdump" on hand, especially because tools such as a compiler or package repositories are not on hand on those appliances.

You can download the latest statically linked binary of "tcpdump" via Github:

When attempting to join your vCenter appliance to AD, you may get the following error message when clicking the Join button:

Error
java.lang.reflect.InvocationTargetException

This is known behaviour when running vCenter with an external Platform Service Controller (in HA mode) but the issue may persist even after upgrading vCenter to a new version with the option to switch to an embedded PSC. You can work around the issue by performing the domain join from the CLI (through SSH):

Connect to the vCenter appliance through SSH (if it's still an external PSC, connect to that instead).

Unless shell access is already activated, use the shell command to enter the regular shell.

Run the followin  ...
