Is developerquestion.com a Stack Exchange ripoff, or is there some valid connection to SE? I.e. does it use the Stack Exchange framework (it really looks very similar)?  Interestingly, it mirrors all the questions of the Stack Exchange sites. Unfortunately, the site does not contain any "about" info at all.
of Stack Overflow, all content posted on Stack Exchange sites by their users (i.e. you wonderful people) has been provided to the whole universe under . For my fellow non-lawyers, that license basically means:   Anyone can use any Stack Exchange posts at any time without having to ask for permission Making money off of the copied content is permitted You don't even have to copy stuff from here verbatim; you can just use it as a starting point and make whatever edits you want There are just two rules you have to follow:   You have to provide . Simple links to the original post and author info are just fine. You have to  and allow other people to use your content, as long as they follow these very same rules. How meta!    (If you ever forget any of that, and want to refresh your memory, the license info is linked to in the footer of every page.)  There are, in fact, a lot of people who republish varying amounts of our content for assorted reasons. Unfortunately, there are some Stack Content Republishers Attributing Poorly and/or Excelling at Ranking (SCRAPERs, for short).  In this context, "attributing poorly" means any use that doesn't follow our attribution rules or make any other reasonable attempt at give credit. This can get pretty egregious; I've seen SCRAPERs that not only don't link back to SE originals, but also use fake author info and post dates to make it harder to find originals. By "excelling at ranking," I'm referring to copycat sites that end up higher in Google results than the original SE sites do for the same content. That's not necessarily wrong, but in some cases, it indicates inappropriate SEO hackery.  So, the question is: what can you do if you spot a SCRAPER?
I'm having problems using the UV mapping in blender 2.67. Specifically, I am trying to unwrap a really simple mesh, but the UV map is still giving me a net where some of the boxes are completely out of proportion to the others, which causes the texture to stretch horribly. Here is a picture to illustrate:    The mesh only has those three faces you can see in the picture, and the single seam on the front corner. It's a trivially simple mesh, so I really don't understand why the two side faces are being stretched in the UV map to be the same size as the top face. I've tried clicking the average islands scale button as suggested by some of the answers to other questions but that has no effect. It's frustrating because it seems so simple.  Hopefully someone can show me the presumably simple mistake I am making!  Edit: Just to make this clearer, I have already added a seam as the first answer suggests i do. Hopefully this picture will make that clearer, the yellow arrow is pointing to the edge i seamed. The mesh is only three faces so should only need this single seam. The image shows the mesh from infront and behind/underneath so it should make more sense.    Double Edit: One more picture for clarity on the seam issue. The mesh is unfolding correctly, it is just the scale of the unfolded map that is incorrect (in relation to one another) What exactly are genes, DNA and chromosomes. How do they relate to each other and what is their function? So I am new to biology and I have been reading, and searching the web, but I couldn't understand the whole framework of a cell. So as I understood:    A DNA, is a double chain of Nucleotides (A,T,G,C and a sugar) and a phosphate residue. Some parts of a DNA code a gene and some do not, exons and introns accordingly. As I understand it these the sequences of exons hold genes and the whole sequence is called genome. Now I read in the book Introduction to Computational Molecular Biology by J. C. Setubal and J. Meidanis. that I cite Each cell of an organism has a few very long DNA molecules. Each such molecule is called a chromosome. So each X shaped thing called a chromosome holds one DNA molecule?   Or is each "hand" of the chromosome one complete double helix of DNA so we have 23 pairs of such chromosomes? or is it that each we 23 pairs Xs?   Shouldn't we have just one uniquely identifiable DNA sequence? I am asking this, because I have also read that each chromosome encodes a different part of one's genome. Does this mean we have several DNA sequences?   This is really bothering me, since I can't figure out the correct structure of a cell.   EDIT: Now if each chromosome contains a pair of DNA helices. We have 46 chromosomes so overall within the cell there are 92 DNA sequences? All of which are the same? Or are they different? If they are different how do they code for different aspects of one's genome? Why do I get "Permission denied (publickey)" when trying to SSH from local Ubuntu to a Amazon EC2 server? I have an instance of an application running in the cloud on Amazon EC2 instance, and I need to connect it from my local Ubuntu. It works fine on one of local ubuntu and also laptop. I got message "Permission denied (publickey)" when trying to access SSH to EC2 on another local Ubuntu. It's so strange to me.  I'm thinking some sort of problems with security settings on the Amazon EC2 which has limited IPs access to one instance or certificate may need to regenerate.  Does anyone know a solution? Shutdown and User button missing in panel I've recently run into many questions where to author asks several related questions in one post, many of them asked before.   I'm wondering what out policy is on such questions:   Should I vote-close them as being not constructive? Should I vote-close them as duplicates? Should I leave them be? Or even suggest an answer?    - Each of the questions: Waiting for an AJAX request with selenium, and headless browsing in selenium have been asked here before, but he asked both in one.  I've done my best to search for similar questions here in meta but I was unable to find any, reading appreciated. jQuery get specific option tag text All right, say I have this:  &lt;select id='list'&gt;     &lt;option value='1'&gt;Option A&lt;/option&gt;     &lt;option value='2'&gt;Option B&lt;/option&gt;     &lt;option value='3'&gt;Option C&lt;/option&gt; &lt;/select&gt;   What would the selector look like if I wanted to get "Option B" when I have the value '2'?  Please note that this is not asking how to get the selected text value, but just any one of them, whether selected or not, depending on the value attribute. I tried:  $("#list[value='2']").text();   But it is not working. What does one second after big bang mean? Consider the following statement:     Hadron Epoch, from $10^{-6}$ seconds to $1$ second: The temperature of the   universe cools to about a trillion degrees, cool enough to allow   quarks to combine to form hadrons (like protons and neutrons).   What does it mean to say "from $10^{-6}$ seconds to $1$ second"?   How is time being measured?  One particle might feel just $10^{-20}\ \mathrm s$ having passed and another could feel $10^{-10}\ \mathrm s$ having passed.   Is saying "1 second after the big bang" a meaningful statement? If $a,b$ are positive integers such that $\gcd(a,b)=1$, then show that $\gcd(a+b, a-b)=1$ or $2$. and $\gcd(a^2+b^2, a^2-b^2)=1$ or $2 $ I have been looking at a few scripts other people wrote (specifically Red Hat), and a lot of their variables are assigned using the following notation VARIABLE1="${VARIABLE1:-some_val}" or some expand other variables VARIABLE2="${VARIABLE2:-`echo $VARIABLE1`}"  What is the point of using this notation instead of just declaring the values directly (e.g., VARIABLE1=some_val)?  Are there benefits to this notation or possible errors that would be prevented?  Does the :- have specific meaning in this context? Probability of winning the game "1-2-3" Sci Fi action movie where an elite group of people control business through a game they play online A situation when two or more people speak at the same time The word or phrase I am looking for is quite opposite to that of the situation when people, such as students or sports players, sing their national anthem with the same tone and words.  I want a single word or even phrase that can describe the situation when two or more people speak at the same time with different tone and words . . . and at the end, the listener cannot get what they are saying. This situation can be found while debating, telling a news about any incident or even while complaining.     Due to _____ , the teacher could not get what they are saying.   If it's not feasible to find a noun or phrase for such situation, then here I request to have an adverb standing alone to describe how they are speaking, for instance, what is the adverb for "at the same time"?.  Here is how, I want to convert sentence 1 into sentence 2.        They spoke at the same time, and the teacher could not get what they are saying.   They spoke _____ , and the teacher could not get what they are saying. Importing only certain rows between spreadsheet documents Document 1 has many rows of data.

Jordan normal form for a characteristic polynomial $(x-a)^5$ Write down all the possible Jordan normal forms for matrices with characteristic polynomial $(x-a)^5$. In each case, calculate the minimal polynomial and the geometric multiplicity of the eigenvalue $a$. Verify that this information determines the Jordan normal form.  I found this question in a textbook that I'm using for a test I have tomorrow. I think that I need to use the method for finding the Jordan normal form of a matrix but I can't see how to apply it and I don't have much intuition about the answer...  I'm guessing that there are 5 possibilities since the minimal polynomial can be any factor of the characteristic, but I don't know how to prove this.  Some help would be great for my test tomorrow! Thanks Access parent's parent from javascript object Curve Bevel function, scale? Is there a way to scale up the bevel object on one end of a curve, a little bit over each point?  I notice the vertex "weight" slider will tweak how much influence each vertex has on the others, is there something like this that can scale the bevel object up a little bit?  Preferably with the option to constrain X,Y,Z independently Why can mathematical equations describe this world? Since I want to understand the world, I learn physics from textbooks. But I feel there is a gap between the textbook and the world. I do not know     why the equations in the textbook can control the whole world? How can I bridge the gap? In research, how can one distinguish whether what we do is meaningful in reality or not?   Any help or suggestions or comments will be appreciated. Show reference label when it is undefined When a reference is undefined, LaTeX shows simply [??] which doesn't give much information. I would like it to show the label instead. This is useful when more collaborators work on the same preprint and the references are yet to be done.  I'm using neither biblatex nor natbib. I do use bibtex but it is irrelevant for this question.  MWE:  \documentclass{article}  \begin{document}  This: \cite{undef} should look like: [{\bfseries ?? undef}]  \end{document}
