I'm not sure what the word I need to search for is, to find help if this question has already been answered.    In magazines it's common to pick out words from the middle of a body of text and repeat them in larger font, with the rest of the text flowing around the "\mbox{}".    How do I make such floating "standout" text—not necessarily in red circles? What is the proper phrase to search for that identifies this way of emphasising short bits of text?
How does one write on the outside of a circle?  I am looking for sample files/packages which imitate a magazine lay-out. Specifically a page with two columns having a circular picture between the two columns.    Example of the desired layout, created using Word:

I guess I have been out a bit too long as this message appears:      Your follower tires of waiting and leaves.    There have been other situations where my follower has mysteriously disappeared as well.  How can I find my follower when they get up and leave or disappear into thin air? $\mathbb Z[i]/ \langle 1+2i \rangle \cong \mathbb Z_5$ I am trying to prove that $\mathbb Z[i]/ \langle 1+2i \rangle$ is isomorphic to  $\mathbb  Z_5$.   The only thing that came to my mind was trying to apply the first isomorphism theorem using an appropiate function. If I consider the euclidean function $N: Z[i] \setminus \{0 \}  \to  \mathbb N$ defined as $N(a+bi)=a^2+b^2$, then I can express any element $z$ in $\mathbb Z[i]$ as $z=(1+2i)q+r$ with $N(r)=1,2,3,4$ or $r=0$.   If I define $f:\mathbb Z[i] \to \mathbb  Z_5$ as $f(x=(1+2i)q_x+r_x)=\overline{r_x}$, then it is clear that $f(x)=0$ if and only if $x \in  \langle 1+2i \rangle$. The problem with this function is that it doesn't satisfy $f(x+y)=f(x)+f(y)$ and it is not surjective for if $r_x=f(x)=3 (5)$, then if $r_x=a+bi$, we have $a^2+b^2=3$, which is absurd.  I don't know what else to do, any suggestions would be appreciated. According to the official sources, is the radioactive green crystal that serves as Superman's Achilles' heel actually composed of the noble gas krypton, or is it supposed to be made out of some other substance?

What's going on here? How to boot WUBI installed Ubuntu within Windows 8? I have Windows 8 Release Customer Preview on my laptop. I tried to install Ubuntu on it with Ubuntu Windows installer (I have always used this to install, although that was on Windows 7), it installs and asks to reboot, then immediately Windows 8 boots up.  I do not have the option to choose what OS to boot. How can I boot to Ubuntu? VM is not exactly what I would like to use, but it is an option, however a last resort. Any help? I am seeking suggestions on what may be going in with an iMac I am currently troubleshooting, as it’s displaying behaviour I do not recall seeing before.  Short story  This iMac refuses to boot up. It gets the Apple logo, gets past the progress bar, and then gets stuck on the grey screen for about two minutes before rebooting itself. However, what makes this odd is that I can:   Start the iMac in Target Disk Mode and use it to successfully boot up other Macs. In doing so everything seems to work perfectly fine. Successfully boot the iMac from an external drive and everything seems to work perfectly fine.   Long story  I was presented this iMac about 2 weeks ago as it refused to bootup. That is, it would commence booting up and cycle through the Apple logo and progress bar, but after the progress bar completed it would remain on the grey screen for a couple of minutes before rebooting itself and doing the same thing all over again.   To address this I undertook the following troubleshooting steps:   Resetting SMC - failed Resetting NVRAM - failed Starting up in Safe Mode - failed Starting up in OS X Recovery Mode – failed Starting up in OS X Recovery Mode via the internet – failed Undertook an extensive hardware test using Apple Hardware Test (AHT 3A213) - passed Started iMac in Target Disk Mode and retested hard drive using Scannerz on another iMac - passed Started iMac in Target Disk Mode and reformatted the hard drive and did a clean install of Mac OS X El Capitan 10.11.6 - successful Migrated data from a Time Machine backup - successful   After these steps I tested the iMac for four days with no issues in terms of booting up and using the computer. On the fifth day I needed to manually import seven Apple Mail mailboxes. I did these one by one and six of them imported within minutes.  The last mailbox was showing as being 270 GB in size. I knew this was inaccurate, but I decided to import the mailbox so I could do a mailbox rebuild to correct whatever corruption had taken place. This import took over 12hrs to do but seemed to work fine and Mail was displaying the emails.  I then tested the iMac on and off for another day to ensure it had no problems booting up. This was successful.  I then decided to initiate the mailbox rebuild, but as soon as I did the screen went black and stayed that way regardless of any keyboard shortcuts I tried using. I waited an hour, forced a reboot, and ever since the iMac has returned to its original behaviour of not booting up – it would get past the progress bar and stay on the grey screen for a while before rebooting itself and starting the whole vicious cycle again.  I have again retested the hard drive, processor, RAM and Video Ram by starting the iMac from an external hard drive and using a combination of the following packages:   Apple Hardware Test (AHT 3A213) Scannerz TechTool Pro Memtester (under the Homebrew subsystem)   And now I have a situation where I can boot the iMac from external hard drives, and also use it in target disk mode to boot up other Macs, but cannot use it to boot from its own internal drive.  At present I have isolated the internal hard drive and am running a scan to check for any malware.   In the meantime, I am wondering:   Has anyone come across a similar scenario and, if so, what was the cause? Assuming I find no malware, do I go through the reformat/clean install/migration process again, but this time not import the last mailbox and see whether the iMac works fine? Any other suggestions?   iMac specs are as follows:   iMac (27”, mid 2011) 3.1 GHz Intel Core i5 8 GB RAM AMD Radeon HD 6970M 1024 MB 1 TB 3.5” SATA HD Mac OS X El Capitan 10.11.6 How do I bind a WPF DataGrid to a variable number of columns? My WPF application generates sets of data which may have a different number of columns each time.  Included in the output is a description of each column that will be used to apply formatting.  A simplified version of the output might be something like:  class Data {     IList&lt;ColumnDescription&gt; ColumnDescriptions { get; set; }     string[][] Rows { get; set; } }   This class is set as the DataContext on a WPF DataGrid but I actually create the columns programmatically:  for (int i = 0; i &lt; data.ColumnDescriptions.Count; i++) {     dataGrid.Columns.Add(new DataGridTextColumn     {         Header = data.ColumnDescriptions[i].Name,         Binding = new Binding(string.Format("[{0}]", i))     }); }   Is there any way to replace this code with data bindings in the XAML file instead? How did the Swooping Evil Venom infused rain affect the magical community? I didn't see any wizards drenched in the rain at the end of Fantastic Beasts and Where to Find Them (don't recall, actually). But would the rain equally affect the wizards as it did no-maj's?   This event is something that doesn't necessarily need to be forgotten by the Wizarding community. How would they avoid being obliviated by the rain?  (They could avoid the rain by Apparating, but what about the showers and drinking water?)  This question is picking at my brain. Sometimes when adding an object to the scene I see that all options (on toolbar or in window after pressing F6) are disabled. Can anyone tell me when can this happen? What is causing it and how to revert it - make it enabled again. It worked for me when I restarted Blender and reloaded the scene. However I would really like to know what can cause it? How can I get a list of all the implementations of an interface programmatically in Java? Can I do it with reflection or something like that? Auto-expand TAB character in code formatting Related:       Note that this question, while related, is not the same as the ones linked.  In many cases, when people put code into questions or answers, they copy/paste the code from their editor.  If their editor is using tab characters, the formatting will be broken after the post is submitted.  For example, if a code is indented using TAB characters, then one TAB character in the beginning of a line will be treated as one level of indent and align with the left edge of the code, effectively indenting equally to 4 spaces.  However in the post editor it looks indented twice - the same as 8 spaces.  I often edit other people's posts to improve code formatting and I find this TAB issue being the biggest annoyance.  Most of the times (I think) on SO, we use 4 spaces to format/indent the code.  I think it would be an easy thing to auto-expand TAB characters inside &lt;code&gt; blocks by replacing them with 4 spaces when the post is submitted. How can the Xenomorph see? If you just look at a picture of one there are no eyes readily apparent but they clearly know where they are going. Could their screeching be some form of echo-location?

Configuring ADB for Nexus 4 on Ubuntu 11.10 None of the physics sensors in my game work, I'm trying to create an AI man that chases after a player, but for whatever reason, he just won't sense the player, I've tried copying and pasting the property name just to be sure, but that's not it. I am developing a game with a Minecraft-like terrain made out of blocks. Since basic rendering and chunk loading is done now, I want to implement block selecting.  Therefore I need to find out what block the first person camera is facing. I already heard of unprojecting the whole scene but I decided against that because it sounds hacky and isn't accurate. Maybe I could somehow cast a ray in view direction but I do not know how to check the collision with a block in my voxel data. Of course this calculations must be done on the CPU since I need the results to perform game logic operations.  So how could I find out which block is in front of the camera? If it is preferable, how could I cast a ray and check collisions?
