Testing server indexed in Google Assume our website domain to be www.example.com.   And we have created a separate testing environment within our main domain: Say : www.project.example.com.  So we have two versions within our main domain server. One is for testing and building new updates and the other one is live server.    I see www.projects.example.com indexed in Google which is our testing server.  Is there any option to restrict this testing environment from being indexed in Google?   thanks
How do you prevent web pages from appearing in the Google search index? I have some web pages that Google has indexed. I have now added a robots.txt file to exclude them, but should I also add a noindex tag? If so, then how do I do so?
Angle between 2 points Given the following image:   $\hskip{1.5 in}$   Supposing $A(100, 300)$ and $B(300, 100)$, how can I find the angle $\alpha$ between A and B?  On a side note, what's the main difference between a point and a vector? translating a point to a vector is as simple as Point = Vector? Sometimes I find articles where the terms are interchangable Evaluating $\int_{-\infty}^{\infty}\frac{1}{(x^2+b^2)^2}dx$ Is there an official Marvel Cinematic Universe viewing order? I'm planning on re-watching the currently-released 5 Marvel films prior to seeing The Avengers.  Have Marvel released any sort of official viewing order?  Captain America: The First Avenger seems like the hardest one for me to place in order with the rest.  It takes place prior to the other films, but has the greatest number of references to the other films.  So should it be watched first, or last?  The rest of them are relatively clear, as they're chronological in the order they're released, with the possible exception of The Incredible Hulk and Iron Man 2 happening at the same time. What settings should I be using to shoot "Supermoon"? How to make a WMS GetFeatureInfo request in Leaflet? I am trying to make a WMS GetFeatureInfo request using Leaflet. I can not find something in the documentation to describe this process. Can you please provide with an example demostraing how to do something like this? Extracting embedded images from a PDF Before I started using Ubuntu I used Nitro PDF reader to automatically extract images from PDF files. Is there a PDF reader for Linux that does this?  I would like to be able to extract images faster/easier than when taking a snapshot. Is there a term for someone who "can see multiple perspectives"? A colleague of mine is trying to describe herself as "capable of seeing a situation from multiple perspectives" or "able to look at the big picture from various viewpoints". I feel like there must be a better way to get this point across.  Is there a more concise way to describe this characteristic? $f,\overline f$ are both analytic in a domain $\Omega$ then $f$ is constant? is it true if $f,\overline f$ are both analytic in a domain $\Omega$ then $f$ is constant? I am not able to  find out what property of holomorphic map I need to apply. please help.Thank you.  $f(z)=u(x,y)+iv(x,y)$, $\bar{f}(z)=u(x,y)-iv(x,y)$ Unexpected voltage with switch turned off I'm programming a presentation in LaTeX using the beamer class.  However, it defaults to 4:3 aspect ratio slides, while everything I use is 16:9. Is there an easy way to change this using a command or two? Is there any gold standard for modeling irregularly spaced time series? There are $25$ horses. You can take $5$ horses at a time and race them. Each horse always finishes the race in the same amount of time, and there are no ties. The only information you get from each race is the order that the $5$ horses finished in. What is the smallest number of races you need to find the $3$ fastest horses, in order?   I found this problem on  and cannot figure out the best answer. Please help.

Is it possible to play against and with Xbox 360 players through my Xbox One? What kind of rhetoric is (this particular) "No one ever [...]" The President also knows that we have to stop blaming victims for these crimes.  No one ever asks the person who got robbed at gunpoint in the street -- why were you there, what were you doing, what were you wearing?  What did you say?  Did you offend someone?  We encourage people to come forward.  We don't have to explain why someone took our money.     I think the "No one ever [...]" claim is literally false, and actually obviously so. So, I understand it to mean:          The President also knows that we have to stop blaming victims for these crimes.  No one in their right mind ever asks the person who got robbed at gunpoint in the street -- why were you there, what were you doing, what were you wearing?  What did you say?  Did you offend someone?  We encourage people to come forward.  We don't have to explain why someone took our money.      Supposing that I am right, what is this kind of rhetoric called? "Nobody want to go there," or "nobody wants to go there"? In English, the number 0 is treated as plural. It is then:   0 seconds 1 second    1.2 seconds   2 seconds     Shouldn't it be "nobody want to go there," instead of "nobody wants to go there"?  I also saw in TOEFL that "any __" should be used with a singular.  But I see it very common that it is a plural also.  Why is that?  (updated: example, "we don't have any apples any more" vs "If you get any apple, please let me know.") Body Diode of a MOSFET So for some MOSFETs, specially with Power MOSFETs, the body diode is a flyback diode that (as far as aI can tell) can be conveniently added to the MOSFET's bulk as there already PN junctions (correct me if I'm wrong).  I've looked at the datasheet of a Power P-MOSFET and it has parameters like "Internal Source Inductance" and "Internal Drain Inductance". So, is the build up of reverse voltage on the source and drain sides, when said MOSFET is suddenly turned off, a behavior intrinsic to (at least some) MOSFETs? Or are these from the rest of the circuit, say inductive loads? What is the name of an 80s TV movie where a man acquires endurance powers and quick self-healing ability after a crash with a vehicle containing radioactive material? I'm arriving to the US by air, but departing via land. How do I end form I-94 now that it is only electronic?
