I wrote "She suggested me to go shopping." Why is it wrong?  Can we say one of the following sentences?   She suggested going shopping. She suggested that we to go shopping.   How would you correct my original sentence?
I took an English assessment test online and this was my answer:     Someone suggested to go for a walk.   My answer was wrong and this was the correct sentence:     Someone suggested going for a walk.   Can someone please explain why my answer was wrong?
Comma after introductory words, phrases, clauses: unacceptable, obligatory or optional? I am no native speaker and always confused about the comma in introductory phrases, in particular in prepositional phrases. Is there any hard rule when a comma must be set? If I make a google search for certain phrases, I often find both variants. Typical examples where I am not sure whether a comma must be set are:        First[ly][,] I must phone mother   In this case[,] we must...   For simple problems[,] the algorithm...   From Lemma 1.2[,] we obtain...   For a typical user[,] the algorithm...   In our theory[,] we...   A dark line on the horizon[,] the mountain range we were headed for seemed somehow not as threatening as when we had started out on the trip.   Avidly reading her novel[,] Jane did not notice that her stop was approaching.   To be sure[,] it is not easy to see a solution.   When you get to Rome[,] give me a ring. Understanding the -exec option of `find` I find myself constantly looking up the syntax of  find . -name "FILENAME"  -exec rm {} \;   mainly because I don't see how exactly the -exec part works. What is the meaning of the braces, the backslash and the semicolon? Are there other use cases for that syntax? fp - How to keep running sum in variable? I have this code in my LaTeX:   \FPset{totalHours}{0}  \newcommand{\entry}[5]{     \FPeval{totalHours}{(totalHours)+#5}     #1 &amp; #2 &amp; #3 &amp; #4 &amp; #5 \\ }   Where \entry is meant to be an entry in a time log. The 5th argument is a number representing the number of hours in that entry. I want to keep a running total of the hours in a variable I can print later on, totalHours.   This seems to do the \FPeval but then totalHours gets reset to 0 by the next time I write \entry. What is the correct way to keep a running total? Thanks. While browsing Stack Overflow, I noticed that I lost a lot of reputation:        Is this serial downvoting? Will it be corrected by a rep-recalculation? How often are those done?    Here's a second instance: Why are text format commands used inside braces? Most commands in Latex are written with the arguments inside braces following the command: \command{arguments}. But text formatting options, like \em, or \scriptsize are usually written inside the braces, like {\em some italicised text}. Why is this? What makes these commands different? I'm particularly asking because it seems to make standardisation - of which LaTeX really appears badly in need - more difficult. Tracking down an old sci-fi book I'm trying to track down an old sci-fi book I read when I was a teenager.  The book was at the Cottage Grove, OR Public Library around 1982-1985.  The plot followed a brother and sister who were scientists or spies, or both.  The brother once used a series of pills to change his weight, height and appearance.  Towards the end of the book, the brother takes a space ship that his sister invented, removes a governor so that he can travel faster than the speed of light and goes back in time several hours.  This is really vague, but thanks for any leads you can share. Warning  If you're looking for advice how to make your document look like it's been written in Word, this is most likely not the question you're looking for. This question is mostly of theoretical nature, as it results in tiny differences, which will most likely not be noticed by someone who doesn't allow the use of LaTeX.  Questions that might be more helpful for this matter are:           Question  I learned that MS Word uses a slightly different version of the unit "point" (pt) than TeX does:     The 12 point of Word will be PostScript point, which in TeX would be called 12bp. A TeX pt is slightly smaller: it's 1/72.27 inch, while a bp/PostScript point is 1/72 inch. See also    ( in )  I'm writing a paper that would usually be expected to be "typeset" in MS Word, thus I want to use the same font size as Word would.  How do I set a document e.g. in the "12pt" font size that MS Word would use?  In case it matters, I'm using the article document class, Latin Modern (lmodern) as a font with the T1 font encoding and compile with pdfLaTeX, but input on different set-ups is more than welcome. Usage of: 'since', 'for' and 'in' Should methods in a Java interface be declared with or without a public access modifier? Should methods in a Java interface be declared with or without the public access modifier?  Technically it doesn't matter, of course. A class method that implements an interface is always public. But what is a better convention?  Java itself is not consistent in this. See for instance Collection vs. Comparable, or Future vs. ScriptEngine. Why does jQuery or a DOM method such as getElementById not find the element? Where were the capital ships and bombers? I have a SNP table looks like this  A N N N N N N N N N N N N C N N N C N N N N N N N N N N N N N N N N N N N C N N N C N N N N N N N N N N N N N N N N N N C C N N N N N N N N N N C C N N N C C N N N N N N N N N N N N N N N N N   I want to count total number of N in each row? any idea how to do that I would like to get a USB token to secure my keys. My use case is protection of 3 GnuPG keys that I will be using 10 times per day at least. I plan to create a new key ring from scratch. Because ECC seems more future-oriented than RSA, this is what I chose to use. I'm wondering which USB token to choose as well as which curve.  On  it is said that many people think curves recommended by the NIST or defined by Brainpool have a doubtful origin; therefore, they recommend the non-standardized Bernstein’s Curve 25519. On  one poster says that    He is not aware of any profound criticism of Brainpool curves, and Bernstein’s Curve 25519 is hard to protect against side-channel attacks when implemented in embedded devices.   As a result, I'm a bit lost as to which key/curve to choose. How can I hibernate or sleep my Ubuntu 10.10 desktop and have it "wake up" the next day?  I have seen software that can do this on windows, so it can't be hard on Ubuntu! Strikeout in math mode How can I strikeout words in math mode (similar to \sout with \usepackage{ulem} in text mode)? I've tried \usepackage{cancel} and \(\cancel{1+1=2}\) but that draws a diagonal line. Proving $\mathbb{F}_p/\langle f(x)\rangle$ with $f(x)$ irreducible of degree $n$ is a field with $p^n$ elements I am attempting to prove what the title says, that $\mathbb{F}_p/\langle f(x)\rangle$ with $f(x)$ irreducible of degree $n$ is a field with $p^n$ elements.  I have already proven that for any field $K$ and polynomial $f(x)$ in $K[x]$, $K[x]/\langle f(x)\rangle$ is a field if and only if $f(x)$ is irreducible in $K[x]$. So I know that $\mathbb{F}_p/\langle f(x)\rangle$ is a field for sure. Where I'm lost is figuring out how to know for sure that there are $p^n$ elements. It's fairly clear if $n\in\{ 0 ,1\}$, but I don't think induction is going to help.  I know from a proposition in class that since $F_p = \mathbb{Z}/\langle p\rangle$ and $F_p = \mathbb{Z}/\langle p\rangle$ is an integral domain, $F_p[x] = (\mathbb{Z}/\langle p\rangle)[x] = (\mathbb{Z}[x])/(\langle p\rangle[x])$, but I'm not sure whether or not that's helpful information. I'm having trouble with this functional equation, to find all functions $f:\mathbb R \to \mathbb R$ for which the following is valid for all $x,y\in \mathbb R$: $f(x) + f(x+f(y)) = y + f(f(x) + f(f(y)))$ I haven't been able to pinpoint any solution, nor to prove surjectivity or injectivity. So 0 progress. Tried with $x=y=0, x=0, y=0, x=-f(y), y=f(x)$, and even with some assumptions on bijectivity, but nothing helped. I don't know the source but seems like a pretty difficult problem, maybe even impossible to solve. myOpenID shuts down February 1, 2014; add an alternative login method to your account So I have been tasked to make an array without duplicated values from another existing array. So I did it, but I want to know is there some other better way to do that. Example input/output: Input: 10, 15, 10, 5, 1, 3 Output: 10, 15, 5, 1, 3 So here is my code. #include &lt;stdio.h&gt;  int main(void) {   const int MAX_ARRAY_SIZE = 5;    int m[MAX_ARRAY_SIZE], p[MAX_ARRAY_SIZE];     for(int i = 0; i &lt; MAX_ARRAY_SIZE; i++) {     printf(&quot;Enter number: &quot;);     scanf(&quot;%d&quot;,&amp;m[i]);   }   int k = 0;   int dup = 0;   for(int i =0; i &lt; MAX_ARRAY_SIZE; i++) {     for(int j = i +1; j &lt;MAX_ARRAY_SIZE; j++) {         if(m[i] == m[j]) {             dup = 1;         }     }     if(dup != 1) {       p[k++] = m[i];     }     dup = 0;   }    printf(&quot;The new array without repeated values\n&quot;);   for(int i = 0; i &lt; k; i++) {     printf(&quot;%d\n&quot;,p[i]);   }    return 0; }  I'm not sure if this is the right and simple way I do that. I want some suggestions. Thanks in advance. :) How to access Winter 13's Push Major functionality We are ISV Partners and all of our packaging orgs have been upgraded to Winter 13. One of the features of Winter 13 was supposed to allow us to push major release versions to subscriber orgs. I would have expected it to be in the previously existing "Push Upgrade" section of our packaging orgs, but that still only allows pushing patch versions.  If it didn't make the final Winter 13 release, I would have expected Salesforce to take it off the release page. Is this something we have to ask to be enabled?
