I inserted this string into mysql database;     Montpellier president Louis Nicollin has revealed his relief at not   selling Remy Cabella to Newcastle for €8 million (£6.5m) after the   player was called up to France's World Cup squad.   But i found following string when i viewed the database:     Montpellier president Louis Nicollin has revealed his relief at not   selling Remy Cabella to Newcastle for ï¿½8 million (ï¿½6.5m) after the   player was called up to France's World Cup squad.   How can i save symbols with other text into my database?
I'm setting up a new server and want to support UTF-8 fully in my web application. I have tried this in the past on existing servers and always seem to end up having to fall back to ISO-8859-1.  Where exactly do I need to set the encoding/charsets? I'm aware that I need to configure Apache, MySQL, and PHP to do this — is there some standard checklist I can follow, or perhaps troubleshoot where the mismatches occur?  This is for a new Linux server, running MySQL 5, PHP, 5 and Apache 2.
Difference between Inheritance and Composition I have a regular C# code. I have no exceptions. I want to programmatically log the current stack trace for debugging purpose. Example:  public void executeMethod()  {     logStackTrace();     method(); } Why is there not a simpler way to calculate the standard deviation? Steps of getting standard deviation. :        Work out the average (mean value) of your set of numbers   Work out the difference between each number and the mean   Square the differences   Add up the square of all the differences   Divide this by one less than the number of numbers in your set -   this is called the variance   Take the square root of the variance and you've got the standard   deviation      Am I missing out something, or why do we need to square the differences in step 3?  Why not simply do a Abs (multiply all negative numbers by -1) in step 3?  Also, my second question is why do we need to divide by one less than the number of numbers in the set in step 5? why not simply divide by the number of numbers? In classical logic, why is $(p\Rightarrow q)$ True if both $p$ and $q$ are False? Prove if f(z) is entire function s.t $|f(z)|\leq M|z|$ then $f(z)$ Is polynomial of degree $1$ Let $f(z)$ be an entire function s.t $|f(z)|\leq M|z|$ ; $M&gt;0$ is a constant then $f(z)$ Is polynomial of degree 1   My try $f(z)$ is entire so it can be written as a $\sum a_n z^n$  $$|\sum a_n z^n|\leq \sum |a_n||z|^n\leq M|z|$$  So $n=1$  Seems that the move $\sum |a_n||z|^n\leq M|z|$ is problematic Is it possible to send an email from my Java application using a GMail account?  I have configured my company mail server with Java app to send email, but that's not going to cut it when I distribute the application. Answers with any of using Hotmail, Yahoo or GMail are acceptable. If $f^3=\rm id$ then it is identity function Let $f:\mathbb{R}\to \mathbb{R}$ be a continuous function such that $f^3(x)=f\circ f\circ f(x)=x$ for all $x$.  How can I prove $f$ is the identity function? Adding a citation after paper is accepted I am a junior researcher in mathematics. I worked simultaneously on proving Theorem A and Theorem B. They both generalize Theorem X in two different directions. Theorem X was proved several years ago (not by me). The proofs of Theorem A and Theorem B use very different techniques, and so I decided ahead of time to write one paper for each.  I finished proving Theorem A before I finished proving Theorem B. Then, I submitted Paper A to a journal (and the arXiv) proving Theorem A. Paper A includes a survey of related problems in the introduction. After a short while, I managed to prove Theorem B, and two months after the submission of Paper A, I submitted Paper B (to a different journal, and also to the arXiv). Now, six months after the submission of Paper A, it is accepted with requests for minor corrections. There is no response yet regarding Paper B.     In this situation, is it a reasonable/common to add one/two sentences to the survey in introduction of Paper A, explaining and citing the arXiv prepreint of Paper B, in addition to the minor corrections the referees asked for? (and letting the editor and referees know that I did that in my answer to their reports which comes along with the corrected manuscript).   Note that I am not asking if it is ok to cite a preprint. This is something I do, and so do other people, at least in math. My question is about making a change, after acceptance, which was not asked by the referees and the editor. What does a confidence interval with a negative endpoint mean? What are the differences between Desktop, Server, and Alternate Installs? Is there a way to add an error on a dynamically referenced field? Let's take this simple example:  opp.get('Name').addError('Invalid name');   This is not working, I'm looking for a similar minded way.  Thanks Commas for multiple adjectives Diagonalisation and characteristic polynomial Let $A\in M_3(\Bbb R)$ which is not a diagonal matrix. Let $P$ be a polynomial (in one variable), with real coefficients and of degree 3 such that $P(A) = 0$. Pick out the true statements:  a. $P = cP_A$ where $c \in\Bbb R$ and $P_A$ is the characteristic polynomial of $A$;  b. if $P$ has a complex root (i.e. a root with non-zero imaginary part), then $P = cP_A$, with $c$ and $P_A$ as above;  c. if $P$ has a complex root, then $A$ is diagonalizable over $\Bbb C$.  I guess b and c are true although I am unable to disprove a. Because A could satisfy $(X-A)$ but this is not a polynomial. Now if $P$ has a complex root, then its conjugate too is its root as the polynomial has  real coefficients. As we all know An odd degree polynomial has always a real root, what we have is three distinct roots. Since $A$ satisfies the polynomial the only difference between the characteristic polynomial and $P$ has to be a constant. Outlook autocleaning my line breaks and screwing up my email format I'm sending an email using the dotnet framework. Here is the template that I'm using to create the message:  Date of Hire: %HireDate% Annual Salary: %AnnualIncome% Reason for Request: %ReasonForRequest%  Name of Voluntary Employee: %FirstName% %LastName% Total Coverage Applied For:  %EECoverageAmount% Guaranteed Coverage Portion: %GICoveragePortion% Amount Subject to Medical Evident: %GIOverage%   When the messages is received in outlook, outlook tells me "Extra line breaks in this message were removed". And the message displays like this:  Date of Hire: 9/28/2001 Annual Salary: $100,000 Reason for Request: New Hire  Name of Voluntary Employee: Ronald Weasley Total Coverage Applied For:  $500,000 Guaranteed Coverage Portion: $300,000.00 Amount Subject to Medical Evident: $200,000   Note how Outlook incorrectly removes needed line breaks after the name, EECoverageAmount, etc...  It's important for the email recepients to get a correctly formatted email, and I have to assume that some of them use outlook 2003. I also can't assume they will know enough to shutoff the autoclean feature to get the message to format properly.   I have viewed these messages in other mail clients and they display correctly  some more information:   I am using UTF-8 BodyEncoding (msg.BodyEncoding = System.Text.Encoding.UTF8) The msg.Body is being read from a UTF-8 encoded text file, and each line is terminated with a crlf.   Question: How do I change the format of the message to avoid this problem? Is $\frac{\textrm{d}y}{\textrm{d}x}$ not a ratio? In the book Thomas's Calculus (11th edition) it is mentioned (Section 3.8 pg 225) that the derivative $dy/dx$ is not a ratio. Couldn't it be interpreted as a ratio, because according to the formula $dy = f'(x)dx$ we are able to plug in values for $dx$ and calculate a $dy$ (differential). Then if we rearrange we get $dy/dx$ which could be seen as a ratio.   I wonder if the author says this because $dx$ is an independent variable, and $dy$ is a dependent variable, for $dy/dx$ to be a ratio both variables need to be independent.. maybe? Is there a word with phobia suffix for fear of waking others up? I usually come home after basketball at like 12:30 a.m. and at this time my mom and sister usually sleep (my Dad though is usually up). When I come home, I don't go to sleep right away and will sometimes eat or do something else. When I do so, I do it in stealth, so that I don't wake up anyone. I do out of two things, to be polite as I do not want to wake anybody up and also the fact that if I make a loud noise and wake my mom up, my mom will get mad and lecture me. Does this count as a phobia? In addition, if it does what would the name of it be. Random plot based on a specific random seed Assume you have some objects which have several fields they can be compared by:  public class Person {      private String firstName;     private String lastName;     private String age;      /* Constructors */      /* Methods */  }   So in this example, when you ask if:  a.compareTo(b) &gt; 0   you might be asking if a's last name comes before b's, or if a is older than b, etc...  What is the cleanest way to enable multiple comparison between these kinds of objects without adding unnecessary clutter or overhead?   java.lang.Comparable interface allows comparison by one field only Adding numerous compare methods (i.e. compareByFirstName(), compareByAge(), etc...) is cluttered in my opinion.   So what is the best way to go about this? How can I speed up combat with a large number of enemies? I'm DMing for a campaign where the player characters will sometimes face small squads of creatures, most recently six ground troops and two archers helping out. In this setting, these creatures dominate the land the PCs are in and have an organised military, hence squads of enemies.  Combat tends to go quite slowly, however. Eight enemies and three players means the players spend a lot of time waiting between their turns!  Without reducing the number of enemies in the encounter, how can I speed up combat when the players are fighting many enemies? "The train will leave" vs. "is going to leave" vs. "leaves" vs. "is leaving" From the grammatical point of view all are correct, just the meaning are different, please bring your clarification, thank you.        The Train will leave at 10:00 tomorrow morning.   The Train is going to leave at 10:00 tomorrow morning.   The Train leaves at 10:00 tomorrow morning.   The Train is leaving at 10:00 tomorrow morning.
