Very soon I realised that the task was new to OR  for me.   Which is the correct  preposition to use in this sentence:  to or for ?
In the sentence-     You must wear a suit to an interview   shouldn't the to be replaced by for? Or what's the difference between these two here?
Now that El Capitan is "rootless", is there any way to get dtrace working? I've found dtrace to be an invaluable tool for debugging and troubleshooting all sorts of issues, not to mention the two dozen dtrace toolkit scripts shipped by Apple as part of El Capitan.  On El Cap though, running dtrace usually results in an endless spew of errors making dtrace all but useless. How to find and compare flights carried out by a specific type of plane? $f_n$ converges uniformly on $[a,b]$ to some function $f$ My wife wants a 4th baby, but I don't Live in Florida & work remote for a New York company. Do I owe NY state income tax? I have been down in Florida for the past 3 1/2 years and continue to pay New York state taxes out of the money I earn for a company I work remote for that is in New York.  Should I be paying New York state taxes on this income?  Or do I not need to pay New York state tax because I live in Florida?  Our NY accountant says I need to continue to pay since company is out of NY, however others say I don't need to pay.  Pls advise which is correct. Thank you. Question is :  Suppose $Y\subset X$ and $X,Y$ are connected and $A,B$ form separation for $X-Y$ then, Prove that  $Y\cup A$ and $Y\cup B$ are connected.  What i have tried is :   Suppose $Y\cup A$ has  separation say $C\cup D$ then all i could see is that   Either $Y\subset C$ or $Y\subset D$ as $Y$ is connected and $ C\cup D$ is separation for a subset that contains $Y$.  Without loss of generality we could assume $Y\subset C$  As $Y\cup A=C\cup D$ and $Y\subset C$  i can say $D\subset A$ (I do not know how does this help)  I have $X-Y=A\cup B$ with $A\cap B=\emptyset$  I have not used connectedness of $X$ till now, So i thought of using that and end up with following :   $X-Y=A\cup B\Rightarrow X=Y\cup A\cup B=(Y\cup A)\cup (Y\cup B)$  I do not know what to conclude from this...   I would be thankful if some one can help me by giving some "hints"  Thank you About inter-city and inter-country bus services in Europe I am planning a month-long trip in mid-June to Europe; mainly Italy, Switzerland, France and Spain in that order. I'll like to know about a bus service that I can use while in a country, and to travel from one country to another.   I found this  provided by Eurolines, can this be used within a country for eg.Rome to Florence? I'll really appreciate if somebody can guide which bus service are available in each country and can help travel from one country to another or is it better to book point to point rail tickets. Intuition behind the Definition of Conditional Probability (for 2 Events) What is some intuitive insight regarding the conditional probability definition: $P(A\mid B) = \large \frac{P(A \cap B)}{P(B)}$ ? I am looking for an intuitive motivation. My textbook merely gives a definition, but no true development of that definition. Hopefully that's not too much to ask. What does [&] mean before function? SharePoint Migration 2007 to 2013 We're planning to upgrade an existing farm from 2007 to 2013. I learned that the best way and maybe the only way to achieve this is by migrating in two steps. 2007 to 2010 and 2010 to 2013. The actual farm is a sql-server(2008r2 64 bit) and a sperate sharepoint-server(web-frontend, etc....) I want to keep the sql-server as it is, if possible and we want to install a new 64bit host for sharepoint 2013. We will design a new branding for 2013 afterwards, so we need to keep the content, but not the layout. There's so much about migration available on the web, but Can I find something like best practises? Geometric intuition of improper integrals I am aware that the area under the curve of $\frac{1}{x}$ is infinite yet the area under the curve of $\frac{1}{x^2}$ is finite.   Calculus and series wise, I understand what is going on, but I can't seem to get a good geometric intuition of the problem. Both curves can be shown to converge to $0$ (the curves themselves, not the area), and on the interval from $1$ to infinity, the two curves have nothing intrinsically different. Can someone please provide me with an good geometric intuition of what's going on? I can't find anything on the web, people seem to not want to explain it geometrically. How do I detach a process from Terminal, entirely? I use Tilda (drop-down terminal) on Ubuntu as my "command central" - pretty much the way others might use GNOME Do, Quicksilver or Launchy.  However, I'm struggling with how to completely detach a process (e.g. Firefox) from the terminal it's been launched from - i.e. prevent that such a (non-)child process   is terminated when closing the originating terminal  "pollutes" the originating terminal via STDOUT/STDERR   For example, in order to start Vim in a "proper" terminal window, I have tried a simple script like the following:  exec gnome-terminal -e "vim $@" &amp;&gt; /dev/null &amp;   However, that still causes pollution (also, passing a file name doesn't seem to work). What did the public at large know about the assassination attempt on Palpatine and how he survived it? I mean, for the people of the galaxy, Palpatine was just a politician past his middle ages. How could this man have survived against four Jedi Council members in his office while “unarmed,” say that the attempt “left him scarred and deformed,” and people believe in this? Counterexample for the normalizer being a normal subgroup How do I find a command if I don't know its name? As a Unix beginner, I often find myself wanting to know the name of the command that achieves a particular function I'm after. How can I go about finding out the name of the command, given a description of what it does? Unable to cover get set in apex test class I am unable to cover the following class get set method.

I just got my shiny new Wileyfox Swift – and before putting it to use I want to oem unlock and root it (as I usually do with new devices ;) Trouble is, though  is enabled on the device, and a corresponding line in /etc/udev/rules.d/51-android.rules exists, the device is not seen by adb devices.  I know there are several answers scattered around this site, but they are either hard to find, just cover a specific device, or don't cover all steps I finally needed. So I take this as a chance for a canonical, device-independent question and give it a detailed answer below:  How can I get my Android device seen and used by adb on Linux? What is the status icon that looks like a house? There is a strange icon that shows up in my status bar only when I'm at a certain restaurant. It looks like a cross between a house and wifi.   I suspect it might be a free wifi hotspot or something related to a nearby phone store, but I can't find any information about it in manual for my phone.  See the following screenshot:
