Same environment with different names
Duplicating Environments
I got  question in review. First sentence is:     I know there is a  question, but no answers.   And indeed the two questions are virtually identical. I started to flag as duplicate - but the original question had no answer at the time, so it wouldn't be correct and apparently . (I didn't go so far as to try to submit the flag).  What is the proper action here? How do we want such a question to be handled? Should both (or more) questions stay open indefinitely until either is answered and somebody gets the good idea to do the duplicate linking?   As the new question is essentially a bump to the front page (perhaps with re-tagging), especially in the case where the OP knows that a previous question exist, perhaps something should be done to enable bumping re-emphasizing without writing the new question.  As I wrote this,  actually got an answer. So the old one should now be closed as a duplicate of the new - but my question remains for the case where all known/found duplicate questions have no answer?  Ironically, just before asking this, the "Questions that may already have your answer" gave me ... (Although the suggestion has no answer). So it has been asked before - the comment there even suggest the ability to re-emphasize.

I have a motherboard with just few SATA slots but have to put quite few hard disks in the box, so naturally I easily ran out of free slots.  I wonder if there are forked cables (I have no idea what would be the name for these cables) so I can connect multiple hard disks to a single SATA slot on the motherboard?  PS. Speed is not essential here as all disks contain archived data.

THE CITY OF CARTHAGE WAS THE CENTRE OF THE ANCIENT CARTHAGINIAN CIVILIZATION \OT1/cmr/m/n/12 2   The following is the offending code:  \documentclass[12pt,letterpaper,oneside]{book}  \pagestyle{headings}   \begin{document}  \pagenumbering{arabic}  \chapter{The city of Carthage was the centre of the ancient Carthaginian civilization} The city of Carthage was the centre of the ancient Carthaginian civilization. The city developed from a Phoenician colony of the 1st millennium BC into the capital of an ancient empire.[2] The area of Carthage was before inhabited by Berber people who also became the bulk of Carthage's population and constituted a significant part of its army, economy and administration. Native Berbers and settling Phoenicians in Carthage mixed in different ways including religion and language, creating the Punic language and culture.  The name of Carthage, Latin: Carthago or Karthago,  meaning "New City"   The first civilization that developed within the city's sphere of influence is referred to as Punic (a form of the word "Phoenician") or Carthaginian. The city of Carthage is located on the eastern side of Lake Tunis across from the centre of Tunis. According to Greek historians, Carthage was founded by Canaanite-speaking Phoenician colonists from Tyre (in modern Lebanon) under the leadership of Queen Elissa or Dido. It became a large and rich city and thus a major power in the Mediterranean. The resulting rivalry with Syracuse, Numidia, and Rome was accompanied by several wars with respective invasions of each other's homeland.  Hannibal's invasion of Italy in the Second Punic War culminated in the Carthaginian victory at Cannae and led to a serious threat to the continuation of Roman rule over Italy; however, the Romans gained the upper hand by invading Africa and defeating Carthage at the Battle of Zama in 202 BC. Following the Third Punic War, the city was destroyed by the Romans in 146 BC. However, the Romans refounded Carthage, which became the empire's fourth most important city and the second most important city in the Latin West. It later became the capital of the short-lived Vandal kingdom. It remained one of the most important Roman cities until the Muslim conquest, when it was destroyed a second time in 698.  The ancient Greek philosopher Aristotle wrote extensively on Carthaginian politics, and he considered the city to have one of the best governing institutions in the world, along with those of the Greek states of Sparta and Crete.[5][6]  \section{Topography} Carthage was built on a promontory with sea inlets to the north and the south. The city's location made it master of the Mediterranean's maritime trade. All ships crossing the sea had to pass between Sicily and the coast of Tunisia, where Carthage was built, affording it great power and influence.  \end{document}    The \hbox refers to:      How can I solve this issue using \pagestyle{myheadings}?

I've read stories about border officials searching laptops when crossing the border in one direction or the other. Does this really happen, typically speaking?  As a US citizen, can I be forced to give them my laptop's password for any/no reason? I don't believe they are allowed to deny entry to the US to a US citizen? ....but who knows these days?  Canada can deny me entry for any reason, so that's fine. But in practice, does this even happen in either crossing direction?  EDIT - I've now made the trip. They didn't so much as glance in the direction of my laptop. My biggest issue turned out to be lack of international wireless data service!

So in Civil War, the Black Panther suit seems to give the suit holder some extra speed, because the guy was running as fast as Bucky and Captain America.  So does it give extra speed?

I wanted to run a query to update units_in_stock in the products table based on quantity in order_details, where the associated orders row has been marked as shipped, and has a shipping date.  Here's what I tried:  UPDATE Products SET (Products.Unit_In_Stock = Products.Unit_In_Stock - Order_Details.Quantity) INNER JOIN (     Orders INNER JOIN Order_Details ON Orders.Order_ID = Order_Details.Order_ID     ) ON Products.Product_ID = Order_Details.Product_ID WHERE (         ((Orders.Shipped_Date) IS NOT NULL)         AND ((Orders.This_Order_Was_Shipped) = "YES")         );   When I run this, I get:  Error at Command Line : 1 Column : 45   Line 1, Column 45 is the equal sign in the very first statement that said  Products.Unit_In_Stock = Products.Unit_In_Stock - Order_Details.Quantity   Can you help me get this working? Failed to fetch jessie backports repository I'm using a docker image as a base for my own development that adds the jessie backports repository in its Dockerfile and uses that to install a dependency. This image uses the following command to add the repository:  echo "deb http://ftp.debian.org/debian jessie-backports main" &gt;&gt; /etc/apt/sources.list   The problem is that fetching packages from the backports repository now  fails with the following error (this used to work previously):  W: Failed to fetch http://ftp.debian.org/debian/dists/jessie-backports/main/binary-amd64/Packages 404  Not Found  W: Failed to fetch http://deb.debian.org/debian/dists/jessie-updates/main/binary-amd64/Packages  404  Not Found   I looked on that server, and those paths are indeed not present there.  I tried to figure out on the Debian backports site whether this particular repository should still be available, and I didn't find any indication that this was deprecated or something like that.  Is this a temporary issue with the repository, or is the jessie-backports repository not available anymore? And if this is not a temporary issue, what options do I have to use this or an equivalent repository without upgrading to the newer Debian stable version? Root of unity for $n+1$ Let $n \ge 1$ and $u_{1},u_{2},...,u_{n}$ are all root of unity for $n+1$ and there are different from $1$.(a) Find polynomial $f \in \mathbb R[x]$ of degree $n$ for which: $f(u_{k})=0$ for $k=1,2,...,n$.(b) Calculate real coefficient and imaginary part for $(2-u_{1})(2-u_{2})\cdot...\cdot(2-u_{n}).$    I have a knowledge about root of unity but I completely don't know how to do it because I think that I need some extra trick to do it but my ideas finished. I know that $\varepsilon_n^{(k)} = \cos\left(\tfrac{2k\pi}{n}\right) + i\sin\left(\tfrac{2k\pi}{n}\right) = e^\frac{2\pi i k}{n}$ and for $n&gt;1$ $\sum _{{k=0}}^{{n-1}}e^{{\frac  {2\pi ik}{n}}}=0$ but I think it is too little knowledge to solve this task.Can you help me?
