How to resolve merge conflicts in Git repository? I want to resolve merge conflicts in my Git repository. How to do that ? How can I double the newlines in an output stream Oven Temperature: How to be sure the selected temperature is correct. I suspect that my - fairly new - oven gets too hot, so I bought an oven thermometer, which confirmed this.  So I called the supplier.  They say that in order to obtain the correct actual  oven temperature, for any setting, you take the highest reading on the thermometer, and the lowest, and then divide both readings.   Is this correct? LOAD DATA INFILE easily convert YYYYMMDD to YYYY-MM-DD? Revision history suggests that I edited the post body, whereas I didn't I was doing some re-tagging and I noticed that the automatically generated revision comment says that I edited the post body where I only edited the tags. In my D&amp;D 5e campaign one of the PCs who's a wood elf started dating a dark elf, and as a result she got pregnant and she is about to give birth. One of the other players had their PC die and he is considering playing as the child of the couple.  My question is, which race is the child going to be? How to compile bibtex with TeXstudio? I am trying to use bibtex for the first time. I am on windows 7, using TeXstudio. I am trying to follow the steps of .  I have created a .bib file, put it in the right directory and written the code in my .tex file. However, I do not know how to compile bibtex with TeXstudio (I looked around in the menus but didn't find it).   Most tutorials I found don't explain how to do it, or say to run a command, which I'm not sure how to do.  Any help much appreciated! For some reason all of a sudden when I update cells in Excel, my equations are not being updated.  For example, I have a simple equation =SUM(C4:C16).  If I change any of the cells in C4-C16, the answer doesn't get updated...  I don't know what happened I've never seen this fail before.  Any ideas? I am interested in displaying some things (e.g.: title page) in full color on screen, while having the same object/page display in a black and white friendly form when printed.  According to , there is built-in functionality in the PDF specification for Screen-Only objects and Screen-And-Print objects.  There may also be a way to add a layer on top of the B&amp;W page that only displays the full color page on screen via the PDF 1.5 Optional Content Groups feature.  Similarly,  demonstrates the selective printing of text via ocg-p.  But it is not clear how I can use this package in the way that I need to.  My scenario is compounded by the fact that my color page text is white on a dark background.  MWE:  This code presents the way I am currently switching back and forth between color and b&amp;w.  I change the printincolor bool variable to make the change.  \documentclass[11pt]{article}  \usepackage[demo]{graphicx} \usepackage{etoolbox}  \providebool{printincolor} % Will set color title page and section headings \setbool{printincolor}{false}  % Setup color if needed \ifbool{printincolor}{% \usepackage[pagecolor=none]{pagecolor}% \definecolor{MyBlue}{HTML}{1b3667}% \usepackage{afterpage}}{}  \begin{document}  % Begin Title Page {  \thispagestyle{empty}   \ifbool{printincolor}{%   \pagecolor{MyBlue}%   \afterpage{\nopagecolor}}{}   \begin{center}   {\ifbool{printincolor}{\color{white}\sffamily}{\sffamily}%  Set text color white or leave [default] black   \ifbool{printincolor}{\includegraphics[width=1.5in]{logo-gold}}{\includegraphics{logo-blue}}% put logo gold or blue   \\ \vskip 1in   \begin{huge}         \textbf{Title}         \vskip 0.1ex\rule{0.5\textwidth}{0.8pt}\vskip 1ex         Subtitle         \\         \end{huge}   \vfill\vfill   \begin{large}    Authors:\\   John Doe and Jane Doe\\   \end{large}   }   \end{center} }  \end{document}   How can I layer (or otherwise display) two versions of the title page in a way that color displays on screen, but black and white is printed? How to tail multiple files using tail -0f in Linux/AIX Does it have or has? Why is the [I'm Done] button unavailable after only flagging comments in the First Posts review queue? I just flagged two comments during a review of a question in the First Posts queue (on another SE site). Then I wanted to select the button I'm Done, but it's unavailable (I can only select No action needed). Even if I refresh my page (while still on that review page), it remains the same.  If however I also downvote the question (only temporary, as a test, since I don't want to downvote the question being reviewed), then it seems to work as I'd expect it to: the button I'm Done becomes available, and No action needed becomes unavailable.  Why is the I'm Done button unavailable after only flagging comments in the First Posts review queue?  Notes:   I'm not convinced that you're supposed to review the actual post, and not (only) the comments underneath it (as mentioned in 's comment). Because "if" I would post a new comment, or just upvote an existing comment, I can actually select I'm Done. While in this case I flagged existing comments which IMO had become obsolete. Flagging comments is "acting on comments". And if my flag gets accepted (in this case: "no longer needed"), and the comment is actually deleted (by the mod), then it makes the question a bit more readable (= don't waste your time digesting a comment which is obsolete). Therefor "IMO", in the end I also "acted on the post". Think about all those posts with a zillion of comments, of which many are obsolete (e.g because the post got updated already). I am not sure (yet) if a similar issue exist in any other review queue (i.e. the Late Answers queue). How to study/prepare for the Salesforce Developer Certification I am fairly new to Force.com development (less than a year). I did not learn it from the ground up. So I think it will be good to study for the developer exam to strengthen my basics and improve my overall knowledge of Force.com + it will be great to have this certification.  Now it's surprising that there is not a lot of great information on the web about how to go about obtaining this certification. Most other major certifications have dedicated study guide books available but there are few for Force.com and I don't think any of them are official.   The official page has little information. The Study guide gives a broad description of the topics in the test.   I see a lot of the esteemed members are here certified developers. I think if you guys could give us a little information, hints/tips and some advice on how to prepare for this exam, it will really be of great help. Also is DEV401 required/helpful?  Also if we could get recommendations for great resources(books, online training etc) and practice tests it will be awesome. Test of whole distribution for two samples The "I Get It" Reputation Problem I wrote a question about blocking certain characters in passwords. It became tremendously unpopular, and it seemed like everyone wanted to rain on my parade every day.  Eventually, I "got it," agreed completely with what people were saying to me, and just wanted to withdraw my question so that my reputation didn't slide even further downhill.  Unfortunately, the system is designed such that I can't withdraw my question or redeem myself. Instead, I just get daily reputation attacks. That's a terrible system, and it needs to be changed. Existence of irreducible polynomials over finite field Let $F$ be a finite field. How do we prove that for each $n \in \mathbb{N}$ there is an irreducible polynomial of degree $n$?  One can assume that $F = \mathbb{F}_{p^m}$ where $p$ is prime. If $n \ge |F|$ then I can construct an irreducible polynomial, namely  $ p(x) = 1 + \prod_{j=1}^{|F|} ( x - a_j )$  where $a_j$ are all the field elements. It is clear that $p(x)$ has no roots in $F$.  This trick doesn't work for $n &lt; |F|$. A counter-example: Let $F = \mathbb{F}_3$ and $p(x) = 1 + (x-1)(x-2)$, then $p(1) = 1$, $p(2) = 1$, $p(0) = 1 + (-1)(-2) = 1 + 2 = 3 = 0 \pmod 3$.  I know there is a way to count them using the Möbius function $\mu(n)$ but I want a proof without it that just shows existence. Why I can't escape spaces on a bash script? I'm trying to escape the space char for a path in Bash, but neither using a  or  works.  .sh script:  ROOT="/home/hogar/Documents/files/" FILE=${ROOT}"bdd.encrypted" DESTINATION="/home/hogar/Ubuntu\ One/folder"  mv ${FILE} ${DESTINATION}   After execute the script (./file) this is the result:  mv: target 'One/folder' is not a directory   Why does the mv command split the string, and how do I stop this from happening? In Windows, if you right-click a .bat file, there's an "Edit" option, which opens the .bat file with notepad. How do I make Windows use Notepad++ instead?  Note that this is different from the question . In that question, user asks for a way to make Notepad++ the default opener for specific file types. This is not what I want here, since I expect that double-clicking on .bat files executes them. Assigning point IDs to respective start and end attributes of polyline? So in the image below there are two circles, how can I remove the internal vertices between them without messing up the outside shape. I'm working on a gun and this is just a simple way to illustrate the issue I'm dealing with. If I where to go in and delete the internal faces it would leave holes on the outside of the object, is there a fast way to get around this?
