"Guess What am I cooking" vs "Guess What I am cooking"
How is "Can anyone tell me how can I solve this" wrong?
Is tipping mandatory at Restaurants and Bars in Germany? In Bavaria, I paid for my drink, I asked her for "Ruckgeld", but only got the integer part of the money back, the rest of it, she kept it for tip! I looked her in the eye and she understood that I wasn't happy with that "initiative", but wouldn't blink an eye!  My company advised me to let it go, mentioning that if I was going to ask for the change, she would swear.  Notice how she didn't return me the correct amount back and then stare at me, demanding for tip, but she would decide for me!  Since, I will be around for a week or so, I was thinking of paying the exact amount of money next time. Will I get in an uncomfortable situation of having the waiter stare at me, demanding a tip? In other words, is tipping mandatory in Germany?    PS: Having experienced the tipping-cruelty in USA, and having tipped generously waiters across the Mediterranean for their supreme behavior, this Saturday night came as a shock, since I had the impression that this awful habit was only a USA-thing (you know, just like the fake audience laughing they have in USA TV series :) ). If $R_{1}$ and $R_{2}$ are relations on a set S with $R_{1};R_{2}=R_{2};R_{1}$. Then $R_{1}$ and $R_{2}$ are bijective maps For the surjectivity part, I showed that if $(a,b)\in I$ then $(a,c)\in R_{1}$ and $(c,b)\in R_{1}$ and $(a,c)\in R_{2}$ and $(c,b)\in R_{2}$ for some $c\in S$. Now for arbituary $(x,y)\in R_{1}$ we have $(x,z)\in I$ which implies that $(y,z)\in R_{2}$. But also $(y,z)\in R_{1}$, so $R_{1}$ is surjective. Similar argument for $R_{2}$  And for Injectivity, I've tried to show that if $aR_{1};R_{2}c$ and $bR_{2};R_{1}c$, then $a=b$ but I am not entirely sure what $a=b$ means in this context. Do I have to show that there is an equivalence relation containing (a,b)?  edit: $R_{1};R_{2}$ is a composition of two relations and $I=R_{1};R_{2}$ Using \ttfamily with \bfseries (or how to enable bold in fixed-width font) I'm using listings package, and I've added basicstyle=\ttfamily\footnotesize. However, when I do that, the keywords from the embedded source-code are not bold anymore.  I figured that \ttfamily together with \bfseries does not work.  And then I found a , and I tried adding \usepackage[bold-extras], and it didn't work either. What does that package do? Should I just ignore it and move on?  And then I finally found , which may be a duplicate to this one, but was a lot harder to find. I also found , which got me more confused.  So, what should I do in order to get a bold fixed-width font for use within listings?  Using pdflatex from texlive-2010. Which past tense of "to light" should I use here? I know that there are two ways to form the past tense of to light (i.e. lit/lighted). Which one is appropriate for the sentence below?     His thoughts lighted our way.   or     His thoughts lit our way. Are the tags shown in a particular order? I noticed that, sometimes, the tags I add to a question are not shown in the same order I wrote them, when the question is saved. Are they shown in a particular order? If they are, in which order they are shown? CSS alignment issues on close reasons with pending votes "Should" word in italics is shifted down in the vote-to-close popup when there is at least one pending close vote.  Just have a look at this:        Now without close votes:        So the issue occurs when there is a close vote on it. It doesn't look good.    Tested on Chrome 27.0.1453.116 m, Windows XP. And it looks fine on Firefox 21.0 and Opera 12.02 (Windows XP)  Here is an example of a slightly different but obviously related problem in Windows 7 SP1 and Firefox 21.0:    This seems to have something to do with how line-height and/or margin attributes are being interpreted.  Can this be fixed? Gnome Panel becomes fully transparent when window is not maximised! What does the plus sign do in '+new Date' How can I get the current working directory? I want to have a script that takes the current working directory to a variable. The section that needs the directory is like this dir = pwd. It just prints pwd how do I get the current working directory into a variable? Lorentz Invariant Integration Measure Why is the multiplicative group of a finite field cyclic? Align multiple numbered aligned blocks There are many discussions over how to align multiple align environments with interspersed texts. However, I want to label multiple aligned blocks such that each number will center vertically for each aligned blocks and at the same time align across blocks.  Here is a MWE that achieves either at one time. The first part simply uses one giant align environment with some \nonumber directive. The second one use equation to wrap aligned but lose alignment info. How should I achieve the best of both worlds?  \documentclass{article} \usepackage{amsmath} \begin{document}   % Part I   \begin{align}           x^2 + y^2 &amp;= 1 \\                 z^2 &amp;= 0 \nonumber \\     x^2 + y^2 + z^2 &amp;= 1   \end{align}    % Part II   \begin{equation}     \begin{aligned}       x^2 + y^2 &amp;= 1 \\             z^2 &amp;= 0 \\     \end{aligned}   \end{equation}   \begin{equation}     \begin{aligned}       x^2 + y^2 + z^2 &amp;= 1     \end{aligned}   \end{equation} \end{document} Shocking? - MacBook stubby earthed charger UK I have no idea why. But apple have not earthed the stubbly plug for the macbook pro transformer. So on the short lead the only way the charger is earthed is when I touch it or the macs unibody which gives you a sort of vibrating feeling on your palms.  When I went to the genius bar to complain about it they said that it was completely 'normal'. Where their definition of normal is that every MacBook does it. I have had 4 MacBooks and all have done it.    The genius did say that he though he has seen a few earthed 3pin plugs. So my question is where can I pick one up? or how could we force apple to earth the stubby plugs and recall them? Currentsection TOC in scrartcl? I like to get a toc at beginning of some of my sections, like in beamer where I can use \tableofcontents[currentsection] is there a possibility in scrartcl?

What is the difference between linear regression and logistic regression? How can I see the "implementation" of protected commands such as \LaTeX? After reading another question relating to how to see definitions of commands, I tried:  \documentclass{article} \begin{document} \show\LaTeX \end{document}   But this shows me in my logfile:  \LaTeX=macro: \protect \LaTeX   I just want to see where the \LaTeX command deep down somewhere finally says "OK, make the 'L' big, then make a little raised 'a,' then ..." Can I install Windows OS (Windows 7) on a removable USB hard drive? I wanted to take a sneak peek at Windows 7 so I thought of installing it. I have Windows Vista on my laptop which came pre-installed with it. I didn't want to mess with it.  So I created a partition (20 GB) in my USB external hard disk and tried to install Windows 7 on that partition. But when I booted from a Windows 7 DVD and selected the target partition on USB hard disk, it said it cannot be installed.  Is there any way to install Windows on an external USB hard disk? Cannot locate Ubuntu Software Center via Firefox to open APT links I'm trying to locate where the Ubuntu Software Center is to choose as default for handling APT links in Firefox.  I can click on the links, and I get the pop-up, but Ubuntu Software Center is not there.  I tried to choose an application through Firefox's settings and through the pop-up, but I don't know the path.  As you can see by my screen shot for the pop-up I chose the wrong one as that doesn't work.  What is the correct path I need to select the correct file?  EDIT - I added a fourth screen shot.  I don't have it in that location.  This is what I have.  My view is in ABC order, and it's showing hidden files. Entire function problem: translation
