Are the following contractions okay to use:  The man's working on the roof for The man is working on the roof The dog's running behind the ball for The dog is running behind the ball
How compelled should I feel to use non-contracted forms (do not rather than don't and so on) when writing in a rather formal text, say an academic paper? In one case I am afraid to seem too stilted, in the other, too casual. Are there good guidelines?  And are there differences in this regard between British and American English?  (In this  there was not much more than "Contractions are more frequent in informal than formal contexts".)
country code TLD vs second level ccTLD I'm really worried about professionalism.  My site would be something like http://mywebsite.uy instead of http://mywebsite.com.uy.  What do you think about this practice? What should I have in mind at the moment of choosing one? As the topic is there exist a homeomorphism between either pair of $(0, 1),(0,1],[0,1]$ LaTeX figures side by side Why do bridge non-Captain officers commonly go on away missions? Ever since the days of Kirk, Spock, and McCoy, bridge officers in Starfleet have always had a prominent role in away team missions.  However, it would seem more logical to me that such hazardous (and, generally, specialized) duties should fall to lower-ranking and/or more dedicated teams.  Of course, it wouldn't have made for great TV if every away team was comprised of a bunch of red-shirts.  And it would definitely increase the show's budget to have an extra group of main characters whose sole purpose was to handle the away missions.  Still, I'm curious to know if there's ever been a real in-universe explanation for this practice?  I know it's been brought up a few times, in a few series/movies, that the Captain should not be taking part in hazardous away team missions.  But nothing is ever said (that I'm aware of) of the rest of the still valuable bridge crew or other senior officers. Using a Single system() Call to Execute Multiple Commands in C In an information security lab I'm working on, I've been tasked with executing multiple commands with a single call to "system()" (written in C, running on Fedora).  What is the syntax that will allow me to execute more than command through system()?  (The idea being you could execute arbitrary commands through a program running on a remote computer, if the program interacts with the OS through the system() call.)  I.e.:  char command[] = "????? \r\n";  system(command); How do you override page.tpl.php in Omega 4? I am using the  base theme, and am trying to override page.tpl.php.    This file is in the base theme in sites/all/themes/omega/templates/system.  When I copy it into my theme, edit it, clear caches, I don't see my changes?  Why can't I override this template? Is there a simple way to change the thickness of a curved tube without scaling its overall size? E.g. scaling the minor radius of an already created torus without affecting its major radius or change the bevel width of a curve that has already been converted to a mesh. I really can't understand what Leonard Susskind means when he says in the video  that information is indestructible.  Is that information that is lost, through the increase of entropy really recoverable?   He himself said that entropy is hidden information. Then, although the information hidden has measurable effects, I think information lost in an irreversible process cannot be retrieved. However, Susskind's claim is quite the opposite. How does one understand the loss of information by an entropy increasing process, and its connection to the statement “information is indestructible”.  Black hole physics can be used in answers, but, as he proposes a general law of physics, I would prefer an answer not involving black holes. how many permutations of {1,2,...,9} How many permutations of {1,2,…,9} are there such that 1 does not immediately precede 2, 2 does not immediately precede 3, and so forth up to 8 not immediately preceding 9? One obvious example of such a permutation might be 987654321, but there are many others, such as 132465879 or 351724698. I am running Ubuntu 12.04 on an IBM ThnkPad T42.  I just installed Gnome and Cinnamon but I am still using Unity.  The only problem is that in dash when I search for any application they don't appear.  I don't see recent applications either.  I fixed it by running unity --reset but the next time I turned on my computer it was broken again How to concatenate two MP4 files using FFmpeg? The Drupal 8 REST UI configuration page asks me to select Authentication providers for GET method; otherwise, it doesn't allow me to export the REST request.  How can I provide anonymous user to access my REST GET API without providing any auth information? How to escape '$' and '#' in Facelets/EL? Probably a basic issue, but still something that irks me and I can't find an answer online. I want to change the default folder for saving new shapes/processing outputs from &quot;last used folder&quot; to &quot;project folder&quot; or &quot;something in relation to project folder&quot; - is this possible? If so, how can I achieve this? Say if I have a dropdown in a form and I have another nested class inside of this class . Now what's the best way to access this dropdown from the nested class? $\mathbb{Q}[x,y]/\langle x^2+y^2-1 \rangle$ is an integral domain, and its field of fractions is isomorphic to $\mathbb Q(t)$ Using a function in two different ways Removing an Ubuntu installation I first had windwos 7, then I installed Ubuntu alongside and when my laptop starts I can choose between ubuntu and windows (the ubuntu boot screen) .  Now I have installed another ubuntu inside the windows 7 using virtual box. I want to remove that first ubuntu installation and free up its partiotion. Can I do it without making any problems for the windows and boot screen?

This force is given by $F=q[E+(v\times B)]$, where $F$ is the force perpendicular to the coil, $E$ is the electric field in the coil, $B$ is the magnetic field, and $v$ is the velocity of the charged particles in the coil. From mechanics, torque is $\tau=F\times r$.  \section{Brushless Motor Fundamentals 2} \subsection{Brushless Motor Operation} \subsubsection{DC Motor Operation 2} If the electrical force is ignored and the remaining magnetic force is used, with the assumption that $v$ is perpendicular to $B$, we find that $\tau=qvBrsin\theta$.  \end{document}   How to show subsubsections and paragraphs in TOC? Is there any way to recover unsaved notepad++ docs? I had to immediate shut down, and I lost about 20 unsaved tabs, is there any way to recover these?
