Given these two choices:   I feel it     my duty to [do something]. I feel it is my duty to [do something].   Which is preferred, and why?    Background: I got confused when reading  where the first variant is used. I was expecting the second.
Over on another network site, a helpful user corrected the grammar of .  The answer now says     I believe it's valid.   where I originally wrote     I believe it valid.   Is the original sentence gramamatically (or at least idiomatically) correct or do I absolutely need a form of 'to be' here? (What's more, is 'to be' a copula or an auxiliary verb if used like this?)  I am quite certain that I have seen sentences like the original one in the past, but I am uncertain where. Given that I am frequently exposed to the somewhat made-up English of authors in the fields of sci-fi and fantasy, I might have fallen into a trap here.  Edit: I don't doubt that the correction is valid and enhances readability.
Why there is "the" before some names but not others Is there a rule beyond the common "no the with proper nouns and names" for the following problem?     I saw the Empire State Building.

In-universe explanation for single line of planetary entry/departure in Star Wars Bluetooth from the command line in 12.04? I've been trying to pair up my bluetooth keyboard with my computer after reinstalling from a standard ubuntu 12.04 to a minimal install.  In the minimal install I have no gui, so I've been trying to use the various command line tools available, but I can't figure out how the pairing is supposed to go. Pairing when I had a gui worked flawlessly.  I've asked for help here:   No one has replied but a lot of details of my situation is available there.

I use TeXworks in Windows7 x64. Stringification of a macro value Hardy's Inequality for Integrals A childish question (literally) -    My 8 year old asked me this morning: "Dad, what does 'physical' mean?" - and I found myself at loss for an ordinary language answer.   Every answer I could come up with ended up sounding like a definition of empiricism: "physical things are those things that can be observed", "physical means something that can be measured", "whatever can be verified and tested", etc....   Claiming that things that are physical are those things which are material or things that are described by physics seems circular.   Google:     phys·i·cal   ˈfizik(ə)l/   adjective   1.   relating to the body as opposed to the mind.   "a whole range of physical and mental challenges"   synonyms:   bodily, corporeal, corporal, somatic; More   2.   relating to things perceived through the senses as opposed to the mind; tangible or concrete.   "pleasant physical environments"   synonyms:   material, concrete, tangible, palpable, solid, substantial, real, actual, visible   "the physical universe"   And various dictionaries (here Merriam-Webster):      Definition of physical   1   a :  of or relating to natural science   b (1) :  of or relating to physics (2) :  characterized or produced by the forces and operations of physics   2   a :  having material existence :  perceptible especially through the senses and subject to the laws of nature   everything physical is measurable by weight, motion, and resistance — Thomas De Quincey   b :  of or relating to material things     lead to similar definitions.   How can one define "physical" in ordinary language terms? Is there a way of defining "physical" that doesn't presuppose empiricism? What is the rationalist definition of 'physical'?   Is there a definition that doesn't commit to either dualism or empiricism or to any epistemology? Help, I cannot get my test code coverage higher than 75%! Code below Create a table with LaTeX How to edit Parameters for an Object after it is created? How to kill applications I have been playing around with Ubuntu installing new themes and and docks. Sometimes during the installation, whole screen just hangs. What is the best way in Ubuntu to Kill a process/application? Anything similar to Ctrl + Alt + Del of windows? With jQuery, how do I find out which key was pressed when I bind to the keypress event?  $('#searchbox input').bind('keypress', function(e) {});   I want to trigger a submit when ENTER is pressed.  [Update]  Even though I found the (or better: one) answer myself, there seems to be some room for variation ;)  Is there a difference between keyCode and which - especially if I'm just looking for ENTER, which will never be a unicode key?  Do some browsers provide one property and others provide the other one? Why isn't  generic?    Seems like Collection&lt;E&gt; could have boolean remove(E o);   Then, when you accidentally try to remove (for example) Set&lt;String&gt; instead of each individual String from a Collection&lt;String&gt;, it would be a compile time error instead of a debugging problem later.

I want to set things up to let more people handle their own projects, with me also being able to go into the server using terminal if I still want to.  I have been following tutorials such as  and a few others.  I figured all of them just teach users how to sftp into their own home folder, also the steps keep saying addUser but some users already existed and removing them might cause some issue.  How can I give existing users the permission to use SFTP for Wordpress projects?  Let's say all my Wordpress projects are already under /var/www/ which has already been set up with www-data:www-data.  Really new with setting things like this.  Thanks in advance for any help. How to manage and restore a modern iPhone or iDevice on ubuntu with iTunes This question—how to install iTunes on ubuntu—has been asked many times before on this site, but the answers are all outdated and involve Wine or some other tool that no longer works for the most recent version of iTunes. Put simply, I need to regularly back up and occasionally restore the firmware on an iPhone 6.   I cannot:   dual boot Windows—for some reason installing one OS makes the other unbootable &amp; after days of headache &amp; dozens of reinstalls I’ve decided to just leave Ubuntu be &amp; not try to preserve Windows. Plus “just use Windows” is not really a solution on an Ubuntu forum. use libimobiledevice-dev. libimobiledevice-dev doesn’t let you manage iOS updates or sync music anymore. Buy another phone. This one should be obvious but for some reason some asshat always comments “too bad lmao shouldntve bought an iphone ;P”. Multiplication principle and permutation Definition of Multiplication principle in Principles and Techniques in combinatorics by Chuan-Chong, Khee-Meng is given as:      Let $$\prod_{i=1}^rA_i=A_1\times\dots\times A_r=\{(a_1,\dots,a_r) | a_i\in A_i, i=1,\dots,r\}$$ denote the cartesian product of the finite sets $A_1,\dots,A_r.$ Then $$\left\vert \prod_{i=1}^r A_i \right\vert=|A_1|\times\dots\times|A_r|.$$   I want to know how this principle is applies in defining $P_r^n=n(n-1)\cdots2\cdot1$, ie, what are sets $A_1,\dots,A_r$ here?

A very similar question is , but the solution of @DavidCarlisle does not solve the more general case. Consider the following MWE:  \documentclass{article} \begin{document} \begin{figure}[ht]   \centering   \rule{1cm}{1cm}   \caption{default}   \label{fig:a very very very long and detailed label} \end{figure} \end{document}   When adding the package showkeys the output is:    Similar problem occurs with the showlabels package (whether the hack of @DavidCarlisle is used or not):   So, is there a way to fix it?
