How to write "<" in LaTeX?
Why do the less than symbol () appear wrong as upside down exclamation (¡) or question mark (¿)?
How do I create a Windows 7 USB installer with preinstalled software? I was wondering if it was possible to make a bootlable image of a Windows 7 Pro OEM Installation CD that I have and put it on an USB stick for faster/easier installation. I am asking because we have a couple of PC´s where I´d have to install the OS using the same key (MAK).  Also is it possible to kind of populate that image with software that would have to be installed anyways on all machines (like Chrome, Outlook, etc)?  It would be really helpful to just install a Windows 7 image with customized software already installed. I would just make an image of an OS and use that, but the hardware of the machines differ. In X-Men Origins: Wolverine,      Wolverine is shot through the head with what appears to be a vibranium bullet by William Stryker. He remarks that the brain will grow back but the memories won't.   So the projectile penetrated the adamantium skull and damaged the brain. Adamantium is an inorganic substance. It will survive anything that would otherwise destroy the rest of Wolverine's body. But if anything (such as vibranium) manages to damage the adamantium, it is not covered by Wolverine's healing abilities.  Does this mean that Wolverine has an Achilles' heel on his forehead? If so, how did he take a bullet to the exact same spot in X-Men: United (at Ice Man's home)? iPhone 6s with iOS 12.4 not connecting to MacBook Pro mid2015 with macOS 10.14.6 A loss and gain problem This is a very simple but confusing puzzle.  A customer buys goods worth $200$ rupees from a shop. The shopkeeper selling these goods makes zero profit from this purchase.  The lady gives him a $1000$ rupee note.  The shopkeeper has no change, so he goes next door to another shopkeeper to get change for the $1000$ rupee note. He keeps $200$ for himself and returns $800$ to the customer.  Later, the second shopkeeper from next door comes back with the $1000$ rupee note with a stamp on it saying "counterfeit" and takes his money back.  How much loss does the first shopkeeper face? "Do the needful" -- Why is it used instead of asking a question? Validation Error less than training error? Why can other users see the files in my home folder? I just added a new, underprivileged "desktop user," and I was surprised to discover that it can see the files in my home folder.  What is the rational for setting up such lax permissions? How does the summoning ability affect the encounter difficulty? The Drow Mage (CR 7) has the Action Summon Demon (1/day), which allows him to summon a shadow demon (CR 4). Is the shadow demon already included in the CR of the Drow Mage, or do I have to count the shadow demon as an extra creature to determine the difficulty of the encounter? How do I unlock all the other ships in the hangar? I'm examining a part of my dataset containing 46840 double values ranging from 1 to 1690 grouped in two groups. In order to analyze the differences between these groups I started by examining the distribution of the values in order to pick the right test.  Following a guide on testing for normality, I did a qqplot, histogram &amp; boxplot.       This doesn't seem to be a normal distribution. Since the guide states somewhat correctly that a purely graphical examination isn't sufficient I also want to test the distribution for normality.   Considering the size of the dataset and the limitation of the shapiro-wilks test in R , how should the given distribution be tested for normality and considering the size of the dataset, is this even reliable? ()  Edit:  The limitation of the Shapiro-Wilk test I'm referring to is that the dataset to be tested is limited to 5000 points.  To cite  concerning this topic:     An additional issue with the Shapiro-Wilk's test is that when you feed   it more data, the chances of the null hypothesis being rejected   becomes larger. So what happens is that for large amounts of data even   very small deviations from normality can be detected, leading to   rejection of the null hypothesis event hough for practical purposes   the data is more than normal enough.      [...] Luckily shapiro.test protects the user from the above described   effect by limiting the data size to 5000.   As to why I am testing for normal distribution in the first place:  Some hypothesis tests assume normal distribution of the data. I want to know whether or not I can use these tests. The problem is stated as follows:  "Let $R$ be a Noetherian ring and $\theta$ be a ring homomorphism from $R$ to $R$. Show that if $\theta$ is surjective then it is also injective."  Regardless of the right solution, I don't understand why is the following wrong:     We have $\theta: R\to R$. By the isomorphism theorem $R/\ker\theta\cong\operatorname{Im}\theta$. Since $\operatorname{Im}\theta = R$, it follows $\ker\theta =0$, so it's injective.   Harsh criticism will be appreciated. Thanks. When sending or forwarding emails using a personal or company domain using a  website or email client, how do I prevent the email from being incorrectly marked as spam? wrong positioning of figure with tabular in xelatex I recently updated MikTex and it seems Xelatex is not able to place figures correctly anymore. Before updating all figures were shown correctly. I work with Texworks and Miktex 2.9  Here it is the code that I run:  \documentclass[10pt,a4paper]{report} \usepackage{graphicx} \graphicspath{{method1/}{method2/}{dpfig/}}  \begin{document}  \begin{figure}[!htbp] \centering \begin{tabular}{cc} \includegraphics[trim=6cm 2.5cm 6cm 2.5cm,clip=true,width=0.33\textwidth]{figure1.eps}&amp; \includegraphics[trim=6cm 2.5cm 6cm 2.5cm,clip=true,width=0.33\textwidth]{figure2.eps}\\ \end{tabular} \caption{Two figures} \end{figure} \end{document} \end{figure}   With this code, figures are correctly trimmed and the relative position between figure 1 and figure 2 is maintained. However, the position in the document is wrong: figure are placed upper and more right than expected (as the bottom-left corner of the table was placed in the middle of the page). The unusual thing is that this does not happen in draft mode and picture are shown centered as it would be.  I usually compile with Xelatex, Makeindex and Bibtex.  I hope to have been clear.. bye!  EDIT: Sorry, I forgot to add the images I prepared from the file that run that script: I need to compile between two and four times before I see changes I make in the editor (TeXstudio) and each time I compile, a new .tex file is created with random letters and numbers at the end.   For example, If I create the file hello.tex and compile two to four times I'll get the file,   hello.tex.QU6664      then I make some small changes in the editor and compile two to four times I'll get the additional file,   hello.tex.Ak6664   After continuing to do this (each time compiling between two to four times before I see the changes I made), I now have many files that look like  hello.tex.QU6664, hello.tex.Ak6664, hello.tex.YX6664, hello.tex.sN6664, hello.tex.Ss6664, ...   A little bit of additional information (in case it's relevant): Everything was working fine up until a few days ago, i.e. only needed to compile once and only the file hello.tex was created. I still only get one .aux,  .synctex and .pdf files. I use TeXstudio to write and compile. I don't think it has anything to do with the bibliography (I tried removing bibliography altogether and still having the same problem).  How do I prevent these additional files from appearing and only compiling once like I used to? Has anyone had a similar problem? I just notice it now as I am new to Illustrator.  When I am in RGB mode, blending transparency seems to be easier as mode such as Screen, Multiply or Overlay looks good naturally.  If I switch the document mode to CMYK then the image is getting messed up.  I'd like to know, if CMYK is not ideal for blending options? The following is an Exercise of Conway's Functional Analysis.   Prove that $X$ is a $\,Banach$ space iff whenever $\{x_n\}$ is a sequence in $X$, such that $\sum \| x_n \| &lt; \infty$, then $\sum x_n$ converges.   I easily can show that if $X$ is a Banach space then $\sum x_n$ converges. My problem is showing that $X$ is a Banach space. For this I suppose that $\{s_n\}$ is a Cauchy sequence in $X$, then I want to make a series. For this I do not have any idea. Please help me. How we can show every permutation is either even or odd,but not both......I can't arrive at a proof for this ..... Can anybody give me the proof...  Thanks in advance... Does it just vanish into space leaving nothing behind or does it expel some material?    Also, talking more about black holes, as far as I understand the term "temperature", it is defined by the amount of kinetic energy of the particles of a body and from what I have read, there are no particles inside a black hole, I know that you can find the temperature of a black hole by analyzing its Hawking radiation but I cant really understand how the term "temperature" can be applied to a black hole. Does it mean that whatever is that it is inside a black hole has kinetic energy? Have physicist already experienced the death of any regular black hole (by regular I mean space-sized black holes not micro ones created in labs)? Also, where is the Hawking radiation form? Because if it is released by the black hole I bet it must have formed outside the event horizon, but how exactly? Forgotten PostgreSQL Windows password I have a .bash_profile in my home directory, but it isn't getting run on login. If I do the following, then things seem to be as I expect:  ssh myhost bash source ~/.bash_profile   But normally that all happens on login. Thoughts?
