I want to dynamically create a sequence of strings by manipulate an array of elements and create some arithmetic procedure.  for name in FIRST SECOND THIRD FOURTH FIFTH; do     $name = $(( $6 + 1 ))     $name = "${$name}q;d"     echo "${$name}"; printf "\n" done   The desire outcome would be the below for $6 equals 0.  1q;d 2q;d 3q;d 4q;d 5q;d   But I get this error  reel_first_part.sh: line 18: FIRST: command not found reel_first_part.sh: line 19: ${$name}q;d: bad substitution reel_first_part.sh: line 18: FIRST: command not found reel_first_part.sh: line 19: ${$name}q;d: bad substitution reel_first_part.sh: line 18: FIRST: command not found reel_first_part.sh: line 19: ${$name}q;d: bad substitution   I guess it's something simple. It used to work when I did something like   FIRST=$(( $6 + 1 )) FIRST="${FIRST}q;d"
Is it possible to tell a Valyrian steel sword from a very well crafted steel sword, by sight alone I'm sure in Westeros there are some incredibly well crafted steel swords, but could someone instantly spot a Valyrian steel sword over one of these?  Does Valyrian steel have any visual indications that it is Valyrian steel and not just a very well crafted steel sword?  I'm wondering, in canon, has anyone seen a sword and instantly recognised it as Valyrian steel.  For the purpose of this question, no one is allowed pick up or use the sword, so they cant feel it's weight, balance, sharpness, etc... Finding a clear difference between truth and fact I have been starting back in school after a long hiatus.  In one of my classes, a discussion of Truth began.  The problem I have had is that no one seems to have a solid definition between the two.   My earlier training and schooling left me with this definition, and I would like some feedback.  Fact - A point of data that can be directly qualified/quantified through confirmed, standardized measurement.  Truth - A point of data not directly qualified/quantified through confirmed, standardized measurement.  So fact would be that ice cream is cold, as we can place a measurement of the temperature.  Ice cream being tasty would be truth, as it is impossible to accurately measure "tasty".  Please let me know your thoughts. Let $y$ be a differentiable function on $\mathbb{R}$. If  $$\lim_{x\rightarrow \infty}(y(x)+y'(x))=0$$ Then how does one show that $$\lim_{x\rightarrow \infty}y(x)=0$$ I'd appreciate some help on this problem. Thanks a lot. Take the function  $$ \begin{cases}f(x,y)=(x^2+y^2)/\sin(\sqrt{x^2+y^2}) &amp; \text{when } 0&lt;\lvert (x,y)\rvert&lt;\pi\\   0 &amp; \text{when } (x,y)=(0,0) \end{cases}$$  I got that this function is differentiable at $(0,0)$. I calculated the partial derivatives at $(0,0)$ of which both were $0$ and trying to show the definition of differentiability is not satisfied but I keep getting that it is. Plz help. Is the force which throws a body on a rotating disk outwards centrifugal force? If some object is kept in a radial groove made on a disk and the disk is rotated with say constant angular velocity.   Now as we know that the object moves outwards ie away from the centre of the disk. I want to know which force is it which throws the object outwards.   As centrifugal force is a pseudo force and hence when the observer is in ground frame it shouldn't be present so which force exactly pulls it out. Applying Insufficient Explanation Post Notice to One-line Questions? Moderators currently have a tool to add a Post Notice that says:     insufficient explanation       We're looking for long answers that provide some explanation and   context. Don't just give a one-line answer; explain why your answer is   right, ideally with citations. Answers that don't include explanations   may be removed.   However, there seems to be no equivalent wording for one-line questions.

I have the problem, that PHP replaces all spaces with underscores in POST and GET variables. For example if I have the URL: http://localhost/proxy.php?user name=Max the browser will convert it to http://localhost/proxy.php?user%20name=Max. But if I give the $_GET parameters out, the key is not user name but user_name (note the underscore)! Is there any possibility to change this behaviour? This is my follow up question. My previous question is here:   Problem:  If I add the image in my table, I get the following output as shown in the image below. Why is the Co-Supervisor going below?

The final product: that I desire is: Adding values to a C# array Comparing and contrasting, p-values, significance levels and type I error I was wondering if anybody could give a concise rundown as to the definitions and uses of p-values, significance level and type I error.  I understand that p-values are defined as "the probability of obtaining a test statistic at least as extreme as the one we actually observed", while a significance level is just an arbitrary cutoff value to gauge if the p-value is significant or not. Type I error is the error of rejected a null hypothesis that was true. However, I am unsure regarding the difference between significance level and the type I error, are they not the same concept?  For example, assume a very simple experiment where I flip a coin 1000 times and count the number of times it lands on 'heads'. My null hypothesis, H0, is that heads = 500 (unbiased coin). I then set my significance level at alpha = 0.05.  I flip the coin 1000 times and then I calculate the p-value, if the p-value is > 0.05 then I fail to reject the null hypothesis and if the p-value is &lt; 0.05 then I reject the null hypothesis.  Now if I did this experiment repeatedly, each time calculating the p-value and either rejecting or failing to reject the null hypothesis and keeping a count of how many I rejected/failed to reject, then I would end up rejecting 5% of null hypotheses which were in actuality true, is that correct? This is the definition of type I error. Therefore, the significance level in Fisher significance testing is essentially the type I error from Neyman-Pearson hypothesis testing if you performed repeated experiments.  Now as for p-values, if I had gotten a p-value of 0.06 from my last experiment and I did multiple experiments and counted all the ones that I got a p-value from 0 to 0.06, then would I also not have a 6% chance of rejecting a true null hypothesis? Prove that $\text{rank}(X^TX)=\text{rank}(X)$ Prove, for real $X$, that $\text{rank}(X^TX)=\text{rank}(X)$.  Could anyone please help me with this problem? I've tried to use full-rank factorization and rank-related theorems mentioned in my book but still failed to solve this. I am learning linear algebra by myself and my book has no solutions manual so I find it really hard to get used to solve linear algebra problems.    Many thanks in advance for your help! In the book "Jurassic Park" does the Lysine Contingency actually get explained? I was watching the movie recently and noticed that one of the characters (very) briefly mentions a safety they built into the system should any of the dinosaurs escape. They called it the Lysine Contingency saying that all the dinos have been genetically modified to depend heavily on lysine in their diet, so if any of them escape they wouldn't be able to survive without the food supplements that the park gives them.   Why doesn't the story end right there? Does the Michael Crichton book actually explain this in depth? I am looking for the name of a sci-fi cartoon. Key plot points  There were Space ships flown by some American voiced crew. They were some kind of rescue squad or maybe space police. In one episode they went to an orange tree farm in a canyon which used mirrors on the canyon walls to direct sunlight to the oranges. They had a force field that protected the canyon but some bad guys came and shot the mirrors. The heroes came back and saved the day. Another episode was set in an underground ancient tomb of some kind that was covered by a sandstorm once they escaped.  Chronology and other relevant information It had kind of 80s or 90s animation. I don't think I ever saw it on TV. I only ever watched the same 3 episodes on VHS. Moving users folder on Windows Vista/7 to another partition When I format the computer and reinstall Windows, my first step is move the My Documents folder to another partition. In Windows XP it wasn't enough because the desktop folder and another user folders was in the primary partition.  Now in Windows Vista and 7 we can use junctions/symlinks to "move" the folder to another partition and Windows and another programs will think that the data is in the primary partition.  What the fastest and secure steps to move the Users folder to another partition and to create the hardlinks correctly? Is it possible to paint only inside a stroke on illustrator? what i actually want to do is paint the same stroke with different colors in diferent segments of it but i can't do it...   Also... I've seen some tutorials that include editing a gradient but that would be very complicated and so would be to make a new stroke over this one, I just hope theres an easyer way XD  Edit per comment:  thats cool but not really what im looking for, what i want is lets say my stroke has the shape of a burger i want part of i to be bread color and part of it to be meat color... not one stroke over the other... i want something like this, imagine the jelly worm is my stroke: I can't see anything - Teams banner and cookie toaster obscure my whole screen There have been  for a while, but this is ridiculous. It reminds me of , but this time it's network-wide.   The banner must be scrolled past (or dismissed) on every page unless both first-party JavaScript and first-party cookies are enabled. If first-party JavaScript is enabled, and the banner is visible, the rest of the page jumps up and down every so often.  Under certain circumstances (not quite sure what they are, yet – a direct link to an answer, maybe? I'm seeing it ) the entire page jumps up and down a line every few seconds even when the banner is off-screen.   The cookie banner keeps coming back unless both third-party JavaScript  are enabled (and  is solved). The cookie box occludes the “Learn more about Teams” link in the banner (with default Firefox window sizes) and the Job / Teams link in the sidebar.  As it stands,  – a site for hobbyists and researchers, whose audience is not very likely to purchase Teams – is much, much harder to use, for no benefit that I can see.
