why do we assume unity feedback system when designing a controller for a system?
Why is unity feedback used?
When I search for my address on Google Maps it cannot be found which means I can't order takeaway etc.  Is there a way of adding my address to Google Maps or even add a street address?  I want the address to be publicly available so others can search it. What is "it" in the following sentence: It is clear that Bob likes doughnuts I am very confused. Unless I am mistaken, I know "it" has to be a noun of some sort, but I am unable to figure out what noun "it" is referring to.   What is "it" in the following sentence:      It is clear that Bob likes doughnuts.   Heres another couple of examples:     It is impossible to fly. Normal text is invisible when using beamer with notes and XeLaTeX C# equivalent to wildcard imports in Java Is there a way in C# to import everything inside a namespace like there is in Java with the wildcard character?  import java.awt.*; Windows 7 File Explorer search not working Windows 10 Icon Gone Missing TL;DR: The Windows 10 upgrade icon went missing. How do I get it back in order to update my system? I am running Windows 7 SP1.   I woke up this morning... er, noon all excited about Windows 10. I had reserved my copy using the clever little icon in the taskbar a few weeks back, so I thought I would be set to go. I booted my computer and checked the icon to see if it would download the update. It still behaved the same as if Windows 10 wasn't launched yet. I supposed this was normal behaviour. After all, Microsoft can't roll out the update to everyone at once.   Windows Update did want me to install several updates though. I installed KB2952664, KB3064209 and KB3048761. Everything went fine, and I was prompted to restart my system.   After restarting, the icon wasn't there anymore. I tried a lot of solutions including the answers provided by our awesome community on , and the answer provided to  posted on the Microsoft Windows support forums.   How do I get the icon back in order to update my system?  UPDATES:   Installing from the Media Creation Tool does not working with an error "Something Happened" with as description "Something Happened". Both are translated from Dutch.  I tried to install it from the Media Creation Tool using PowerISO to mount the created ISO. It will not accept my product key, even though I am able to verify my Windows installation is already registered and the product key is correct. I looked into the Event Log, and GWX-Ins has a bunch of error messages saying: Error message: GWX Main: App failed to start hresult. After that it says what is roughly translated to English as "Cannot find the element". I built a simple bridge rectifier.         &ndash; Schematic created using   I connected the output of the function generator with CH1 of my oscilloscope and  with the input of the rectifier (using a T-Piece). The output goes into CH2.   The original wave looks like this:    After connecting CH2 the picture looks like this:   While CH2 looks good,  CH1 now shows the wave I would expect without capacitator but not the expected original wave.   Could somebody explain why? I'm using a Gwinstek GDS-1072A-U Oscilloscope and a Gwinstek SFG-1003 function generator. I have a bibliography in which a particular author wrote two papers in the same year. Bibtex is sorting them alphabetically by title, but I want them listed chronologically. (So in the example below 'universal grammar' should precede 'English as a formal language'.) What's the appropriate way to flip the order?  MWE:  \documentclass{article} \usepackage{natbib} \begin{document}  ... formal semantics in the  Montagovian tradition \citep{montague1970aug,montague1970befl,montague1973ptq}.   \bibliographystyle{harvard} \bibliography{test} \end{document}   This generates the text 'formal semantics in the Montagovian tradition (Montague, 1970b,a, 1973)' whereas I actually want '1970a,b,1973'.  test.bib file for MWE:  @incollection{montague1973ptq,   title={The proper treatment of quantification in ordinary {English}},   author={Montague, Richard},   booktitle={Approaches to natural language},   editor={Hintikka, K.

I have now almost completed my family tree, having each branch going back to approximately the French revolution, discovering dozens of previously unknown ancestors.  I would like to share the family tree with my family, the problem is that I cannot have a tree in a nice format that could be printed on a standard A4 sheet (maybe using both sides or whathever).  I have a SVG tree that use graphics, but it is unconventionally large and if scaled down to a A4 sheet, the text would be so small that it would not be legible. The maximum width is of about 50 ancestors of a generation, then it goes sparse again.  I'd like to know if a format exist where the family tree (with direct ancestors only) would be printable, with names but also other complementary information, and the format should be printable as not all my family users are particularly skilled with computers. Change default XML comment snippet in Visual Studio When I hit /// in Visual Studio, is it possible to change the resulting snippet from this:  /// &lt;summary&gt; ///  /// &lt;/summary&gt;   to this?:  /// &lt;summary&gt;&lt;/summary&gt; Were these other people Chronicoms? We know that Enoch is a Chronicom, which is to say a sort of alien temporal observer.   When Enoch and his agents came and kidnapped       Coulson’s team,   for the purpose of sending them where they wanted; were these other agents also Chronicoms? I’m inclined to think they must have been (would Enoch have shared their advanced technology and goals, etc. with mere mortals), but on the other hand only one pod was mentioned. Is there is a way to exclude nested subdirectory specified by a path to that dir from grep recursive search? Or I have to use ack or find for this?  Here's what I want. Say I have this dir structure:  dir/nesteddir/match.txt otherdir/nesteddir/match.txt   How do I exclude first nesteddir only? Is it even possible using grep?  Most obvious answer $ grep -r --exclude-dir="dir/nesteddir" "stringToFind" . doesn't seem to work, nor do any of my experiments with various --exclude-dir paths using globbing, leading ./, etc.   Reading man page and googling didn't help, the only mention of this usecase I found is this question:   It was concluded that this is bug introduced in grep 2.12, but I'm using latest version (2.16) and grep's bugtracker () doesn't mention anything related to --exclude-dir, so I guess either it was fixed or it's an intended behaviour.   Would be really nice to get some clarification. I am including pages using Ajax but I also need to include their respective javascript files, which requires removing the previous javascript files from memory at the same time.  How can I unload the currently-loaded javascript files (as well as their code in memory) so that I can load the new page's files? They will more than likely conflict, so having multiple independent files' javascript files loaded. How to install Internet Explorer (multiple versions)? I am developing one site which has chat feature in Rails. I am using Ubuntu 12.04 LTS. I need to check that the site is IE9 because the chat feature using socket io of HTML5. I want to know that how to install IE9 in Ubuntu. I have looked at Chrome and Firefox extensions but if any standalone is available then please give me suggestion. My question comes from what I learned in the movies, considering I have not yet been able to read the books. I would just like to know why Severus Snape called himself the Half-Blood Prince? Did many people call him that or did he just think that it was a cool nickname? This question might be answered in the books so feel free to quote from it. What does Pirsig mean by "Quality"? How can I achieve more clarity in my photos of the moon? I took this photo of the blood moon this morning and I am finding many of my photos, especially landscape photos, have a significant lack of clarity. I'm not looking for a photo critique because I know this particular photo is crap. I'm looking to identify my source of failure to nail a significantly clear photo.     Setup  Canon EOS 70D with a 100-300 telephoto lens (I'm sorry I don't know the exact model. It's from Canon but not one of their professional quality lenses.)   Aperture: f/5.6 Shutter: 1 sec. ISO: 1000 Focal Length: 300mm Metering mode: Spot White Balance: I manually set the WB to 5500 kelvin, it looked fine in live view. Focus Mode: Manual Drive: 2 sec timer delay   Mounted on a decently stable tripod  Process  I turn on live view, and square up the target in the display. I then set my focal length, focus in using live view, adjust the focus as sharp as possible and take the pic. I've noticed that in this case, the picture was incredibly grainy, which doesn't translate to the final photo, but wonder if it has anything to do with it.  This particular shoot I found it difficult to balance out the variables with a dark sky and a moving moon that starts blurring after 1-2 seconds of exposure, which is why I had the aperture wide open and the ISO cranked up.  I can't tell where I'm failing:  Equipment:  The 70d takes great photos but the telephoto is not great when it's totally zoomed in. My wallet doesn't hold enough cash for a motorized mount to track objects in the sky.  Circumstance: I've seen great photos of the moon with the use of a camera and a tripod, so I know this is possible. Although, I keep seeing pictures of this big gorgeous moon over the landscape, and when I use my wide-angle, the moon shows up as a dot. What the hell are people doing to get the moon so big?  Beginner skill level: I know this is the biggest culprit, but being the beginner, I'm unable to know where to adjust. Searching for a string on multiple zip files Short story collection about Transporter "Doors" I'm looking for a short story collection about different uses/inventions of transporter doors. I think it was just a single author collection, that I read in the early 2000s.  In each story these Transporter Doors exist, I seem to remember them being described as blank grey sheets. You step through them and come out somewhere else. The forward to the book talked about early Rocket stories where the launch of a spaceship would be the end of the tale.  Plots of the individual stories:  Two men one of whom's home is inside an asteroid are discussing the use of Base12 in their society and if it is because they have 12 fingers, one says that "people" used to use base10. The implication is that a different species arrived through the doors and replaced humans.  A man puts the code for his home into a door and is instead transported to prison where he's accused of murdering his wife, which he strongly denies.   Two scientists and a pilot take a probe ship deep into Jupiter's atmosphere, the will return to base via a door that they need to construct while they are down there. The scientists dislike each other and don't work well together. When they finish the door, the hamsters seem woosy out the other side, but the scientists insist it is ready. The pilot says he will go first as he can't fix it if it's wrong. When he arrives on the far side he's mentally damaged and the scientists have to get along without him acting as a buffer while the try to save themselves.
