Well... its kinda bittersweet when after 10 minutes composing a compelling post on a technical problem, you figure out the problem right before you hit submit. The tide turns on the bitter side when you spent most of your time formatting the post than composing the text. So... to precent wastage of "knowledge", I post my question, as well as the answer, in the hope that it will help somebody. I was tinkering with the CD-burning API in the Windows Vista SDK, and one of the basic classes needed for that is MsftDiscMaster2 . The MSDN example is in VBScript and does this to create an object of type MsftDiscMaster2 : WScript .CreateObject( "IMAPI2.MsftDiscRecorder2" ) Now, to port this to C-Sharp, the first thing that I tried was this: MsftDiscMaster2 g_DiscMaster = ( MsftDiscMaster2 ) Activator .CreateInstance( typeof ( MsftDiscMaster2 )); It showed me a runtime excption: Cannot create an instance of an interface. However, when I try this round-about way, it works!
So Google has recently publicized the "+1" button for websites, which "competes"  with the Facebook [Like] button and the Twitter tweet button. This is a much more worrisome phenomenon than we give it credit for. Notice how the Facebook like button is instantly able to tell you which of your friends have liked that page? That is because Facebook is able to correlate your Facebook login with every page you visit. In order to see if any of your friends have liked that page, Facebook has to correlate the URL to your friend list. So even if you haven't clicked [Like], even if none of your friends have clicked [Like], just to be sure of that fact, Facebook will send the URL and your Facebook login to its servers, building up your entire browsing history. And now Google has done it. Twitter did it even before Facebook. I implore you, do not let these corporations track you everywhere you go. This will only end badly. Fortunately there is an easy fix.

I recently bought a Lenovo Yoga Slim 7i (Model 14ITL05). I really like it. I am trying to write down everything that surprised me about the laptop in here. These are mostly things that did not understand about the machine from the product page on Lenovo when ordering. I'll start off with the pleasant surprises: There is some sort of radar sensor on the top on the screen, in the webcam area. When I come and sit on my chair in front of the laptop, it wakes the screen and then Windows Hello logs me in with face ID. This is great! There is a feature called Battery Conservation Mode . What it does is: it pauses charging the battery when it reaches somewhere between 55 and 60%. So you can get the full performance out the CPU without adding a lot of wear on the battery. It allows the CPU to go to full performance with all the wattage coming from the AC adapter without worrying about battery wear. However, I would like to know more about this, and exactly why the battery percent
