If I know Andy, the sight of it has sent him into a fugue state and he’ll be distracted until he gets the whole mess sorted out. Meanwhile, I’ve snuck into the control room, wedged the door shut with a curly brace, and seized control of The Index mainframe.

  That’s right — I’m running this show now, and you know what that means: I’m runnin’ a little long, baby. Strap in!

• James G ☛ Adding multiple h-feeds to the same web page

  Every h-feed has a HTML ID that uniquely identifies it. For example, /hwc-notes#hwc-pacific identifies the HWC Pacific notes h-feed on the /hwc-notes web page. Granary, the tool I use to convert h-feed into RSS, can recognise the ID fragment and limit its conversion logic to the chosen fragment.

• Redmond Magazine ☛ How to Remotely Manage Linux VMs With RDP

  Historically, my network has always consisted solely of Windows machines. Sure, I might occasionally bring a Linux or MacOS virtual machine online in my lab, but my production environment has always been based on Windows. Recently however, I have begun experimenting with running Linux in production. Of course, one of the challenges associated with doing so is that of managing Linux VMs alongside Windows Server VMs. Fortunately, there are several options for doing so.
