Which is correct:   The 80s is returning The 80s are returning.   If you say "are returning", then why do we say, "The 80s was a time of....." ?
"the 90s were the best decade ever" or "the 90s was the best decade ever"  "the 90s" and "decade" are both referring to the same singular period of 10 years, so "was" seems to make more sense. "90s were" rolls off the tongue better though.
Plotting graphs using bash I am flying from Los Angeles to Bangalore. I have a flight option from LAX to Minneapolis and from there to Paris. I have only 45 minutes at Minneapolis before my next flight. Is this too risky a schedule? I am not an American, so I guess I would need to cross emigration too? How to set a font for math mode?

Can I run two 4k (3840x2160) displays, both at 60hz on a Macbook Pro 13' 2015? I understand they might need to be SST and each connected to a Thunderbolt 2 port. But I cannot get a confirmation whether that setup would work.    says:     Simultaneously supports full native resolution on the built-in display and up to 3840 by 2160 pixels on up to two external displays, both at millions of colors.   …   Support for up to 5120-by-2880 resolution at 60Hz on a single external display (model with AMD Radeon R9 M370X only)   Unfortunately, it does not state at what frequency the two displays can be run.    says:     With OS X Yosemite v10.10.3 and later, most single-stream 4K (3840x2160) > displays are supported at 60Hz operation on the following Mac computers: … MacBook Pro (Retina, 13-inch, Early 2015) and later.

This seems like an invalid use of an inline code span because, well, it isn't code, and it is distracting. There are a    of these edits being made. Often enough they get approved, which reinforces the behavior.  Is this a valid use of inline code spans? If not, should it be edited and corrected? Should edits suggesting these changes be rejected? Unparsed HTML shows on search result page What can I expect from a Skype interview for PhD admissions? I want to print two files in two columns -- first file on the left side and second on the right side. paste doesn't do the job, because it can only insert a character as delimiter, so if first file lines have different length output will be twisted: $ cat file1 looooooooong line line $ cat file2 hello world $ paste file1 file2 looooooooong line   hello line    world  If it was a command to add trailing spaces like fmt --add-spaces --width 50 the problem would be solved: $ paste &lt;(fmt --add-spaces --width 50 file1) file2 looooooooong line                                 hello line                                              world  But I don't know a simple way to do this. So how to merge and print several files horizontally without twisting? Actually, I just want to look at them simultaneously.  UPD: command to add trailing spaces does exist (for example, xargs -d '\n' printf '%-50s\n') But solution like $ paste &lt;(add-trailing-spaces file1) file2  does not work as expected when file1 has fewer lines than file2. How to Execute ShortCut From Command line in Windows 7 We came with a scenario where we have to use Shortcut file (.lnk), which is on the desktop, to execute an application for a headless device (i.e, without manual intervention).  Is there any way to execute it from Command prompt? What is the solution to the following recurrence relation with square root: $T(n)=T (\sqrt{n}) + 1$? How can I automatically name files being exported based on input parameters How do I execute a program X times in the terminal?  I read that I have to do a bin/bash txt, but I don't know how to execute this X times. In setting up dual Boot with Windows and Ubuntu, which OS do I install first? I'd like to install both Ubuntu 12.04 and Windows XP on a Dell laptop, and I was thinking about using a dual boot structure, and using the bulk of my hard drive as empty hard drive space to share files between the two operating systems (so choice of file system type is very important in this set-up).     The kind of partitioning structure I would like to use is  Partition 1 - Ubuntu 12.04 (root) (20GB)  Partition 2 - Ubuntu /home        (20GB)  Partition 3 : Free Space          (560GB)  Partition 4 : Windows XP          (35GB)  Partition 5 : SWAP                (3GB)  (Total Hardrive Capacity is ~640GB)    My question is; what is the best way to go about setting up this kind this system?   Should I install Windows XP first and setup the partitions, and then install Ubuntu which I believe will install the GRUB bootloader for OS booting choice   or   Do I install Ubuntu first, setting up the available partitions and then perform a WIndows install?  Please let me know if there is anything in this setup that I have left out and should know about, including things related to setting particular partitions as logical or primary, and whether the boot partition and the filesystem partition should actually be two separate partitions. $A^A$ in category of graphs (reference is Lawvere/Schanuel, Session 31, Ex. 1)  I'm trying to calculate the exponential object $A^A$ and its evalution map $e \colon A \times A^A \to A$ in the category of graphs, where $A$ is the "arrow graph" (ie. one arrow and two dots).  In the following, $D$ is the graph with one dot and no arrows, $1$ is the terminal object in this category (graph with one dot and one arrow, the loop).  So far I have:   The points of $\mathbf{1}\to A^A$ correspond to the maps $A\to A$ (via two standard isomorphisms), and since $\mathbf{1}$ is the loop, and there is one map of graphs $A \to A$, there is one loop in $A^A$. The dots $D\to A^A$ correspond to the maps $A \times D \to A$, of which there are four, hence four dots in $A^A$. The arrows $A \to A^A$ correspond to the maps $A \times A \to A$, of which there are four, hence four arrows in $A^A$.   But I'm stuck on how to put these together to constitute $A^A$ and its evaluation map. Question mark or period to end a rhetorical sentence Which makes more sense as end punctuation for the following rhetorical sentence—a period or a question mark?     Maybe you could be a security guard there and enforce whatever the WalMart policy is at that location I changed my username and now I cannot play online Suppose 27 cubes are stacked together, suspended in the air, to form a larger cube.  The cube is then painted on all the exposed surfaces and dried.  The smaller cubes are then randomly permuted in both spatial position and spatial orientation to form another large cube.  What is the probability that new larger cube is identical to the original?  This is not homework, it was passed on by a friend who found it somewhere on the internet, and they do not remember where. Proof of Archimedes Principle Say I have an arbitrary body $\Omega$ and surface $\partial \Omega$ submerged in a hydrostatic fluid of density $\rho$ under the influence of gravity.

This seems like a job for either the / package or the  package.   The voting on the answers to this  suggest that longtable is the preferred package, yet xtab is much newer and has been revised since that question was asked.  What are the differences between xtab and longtable and when is one preferable to the other? Proving the snake lemma without a diagram chase
