At the end of The Force Awakens, Kylo Ren falls into the snow and gets slashed at by Rey several times. A slash mark on his face is clearly visible.  Rey also slashes at one of Kylo's hands as he falls into the snow. Was his hand cut off at that point in time?
Inspired by  which states limb loss as a recurring theme, I started thinking about the final lightsaber battle. After watching The Force Awakens the second time, I was not sure if      Kylo Ren   lost a limb or just lost his lightsaber. We definitely see      Rey slash at Ren’s right hand.   So knowing that context:      Did Kylo Ren actually lose his arm/hand?
Sometimes chicken breast can be thick and I never know how to tell when it's cooked! How can I be certain it is cooked all the way through? Show that if $\sqrt{a}+\sqrt{b}\neq 0$, then $\mathbb{Q}(\sqrt{a}+\sqrt{b}) = \mathbb{Q}(\sqrt{a},\sqrt{b}), \forall a,b\in\mathbb{Q}$ variable access outside of if statement addtocontents not working with certain other packages This is a follow up question on   How do I change the toc dept mid document while using packages (in this case only mathtools).  An example:  \documentclass[a4paper,10pt,oneside]{book}  \usepackage{mathtools}  \begin{document}   \frontmatter             \chapter{hello}  \section{hello}  \subsection{hello}  \subsubsection{hello}   \setcounter{tocdepth}{3}  \tableofcontents   \mainmatter   \chapter{hello}  \section{hello}  \subsection{hello}  \subsubsection{hello}   \chapter{hello}  \section{hello}  \subsection{hello}  \subsubsection{hello}   \appendix   \addtocontents{toc}{\setcounter{tocdepth}{0}}   \chapter{hello}  \section{hello}  \subsection{hello}  \subsubsection{hello}   \chapter{hello}  \section{hello}  \subsection{hello}  \subsubsection{hello}  \end{document}   This example generates an error and very strangely puts an exclamation mark in the ToC as you can see here   however when I comment out the \usepackage{mathtools} it suddenly works again or replacing it with a different package such as \usepackage[T1]{fontenc} also generates no errors.  But this is not limited to just this specific package, certain other packages also introduce the same behavior (I just took this package to keep the example small). Looking for solo (one person) RPGs - do they exist? I am looking to find out if solo RPGs exist, and which you'd recommend.  I do not mean "one-on-one" 1 player + 1 GM games. I really mean "1 person."  Update: After receiving two (fine, up-voted) answers that indicate Choose Your Own Adventure solutions (which rocks with nostalgia), I should add that I'm not looking for simple linear decision tree gaming. A counterexample: I've got my own little creative-writing mini-game where I write out a story, but once every 5 sentences a series of dice-rolls forces my written sentence into something else, and I have to adapt as writer. Not really an RPG, but also non-linear. Should it be /about_us or /about-us?  From usability point of view, I personally think /about-us is much better for end-user yet Google and most other websites (and javascript frameworks) use underscore naming pattern. Is it just matter of style? Are there any compatibility issues with dashes?

How can I get Google to stop thinking I'm a Bot? So, I'm getting the occasional CAPTCHA message, which is irritating but fine, but occasionally Google just blocks my network wholesale. I've submitted automated requests to unblock it, but I have no idea who I can email directly to clarify the issue.  I've run all manner of anti-virus, parsed my router's logs, combed through Fiddler to see if any errant packets were slipping by. Nothing. The only Google searches that happen are made by me through the web-browser.  Who or what do I have to do to get Google to stop falsely flagging my network as a spam-bot? I have 2 storage devices; classical slow HDD (750GB, /dev/sda) and faster SSD (128GB, /dev/sdb). Currently I have installed Ubuntu &amp; Mint on same btrfs partition on SSD (/dev/sdb5). My btrfs pool consists of /dev/sdb5.  What I want to achieve is data replication on HDD while keeping SSD performance: Something like this:  For read case it would be ideal for procedure to go like this:   read from SSD check checksum if it verifies.. awesome, give me the data if not, fetch data from HDD and perform error correction through duplicate data   I'd manually run (some tool I'm not sure which one... btrfs check --repair perhaps?) every month or so to check HDD checksums and correct them via SSD data against bitrot.  For write case:   write to SSD sync to HDD when write requirements are low, thus not slowing down the system.   Is this possible and how would I do it?  Bottom line is, I like btrfs and would like it to duplicate data across HDD &amp; SSD drive automatically while keeping SSD excellent performance.   Using SSD as write cache is not an option since it's missing data duplication and security. I have two large external drives with about 2.5 TB of data. About half the storage is images and videos that I want to put on a new NAS drive/device. I don’t want to carry over junk, duplicates and non photo/video files.   I am hoping Lightroom can help scour the mounds of folder structures on these drives and copy images/videos the new drive that I want to catalogue and keep clean as a working platform for all images and video. Once completed I plan to format the original drives and copy the cleaned-up content back to them as part of a backup strategy.  Can Lightroom help? If so, how? If not, is there some other application for Mac OS X that I can use for help with this? One problem I had with my original attempt is I wasn't sure how to move images and rename folders to get the new drive contents to make sense, so I formatted it and am looking to try again.  (steps for this operation would be helpful) Implementing a PIVOT query How do i prove invertibility of this linear transformation Choosing Geographical Coordinate System and Projected Coordinate System for India? I want to create spatial data for entire India.  Usually I use WGS84 as GCS and UTM zones for PCS in the places in India, but when I have to create the spatial data for entire India, I get confused which geographical coordinate systems and projected coordinate system will be suitable.  What are suitable ones? I need to extrude a circular shape from a surface that's basically just a grid of quads. What's the best practice to do this without screwing up the topology too much?  I basically want to have a circular face I can extrude, in order to have a cylinder like protuberance on the object, something like this: "Where somebody/something at" ? I'm not a native English speaker, so I would like to have an explanation of that expression: "Where something/somebody at?"  Examples :      Where Brooklyn at ? (interlude in a Lonely Island album)      Where you at ? (seen on a game server, instead of Where are you, I suppose)   Are not they supposed to say "Where is/are ..."? I am trying to update Xcode to 8.0. My OS is 10.11.6 El Capitan. However I am getting:     We could not complete your update   There is not enough disk space available to install the product.   I have got 14.22 GB free space. How much do I need?  UPDATE: I do not know the exact figure, though I did manage to update with 17.21 GB free space later on. What color would you see if you place 2 mirrors in opposit when one is a one way mirror Does a Magic Staff count as a magic weapon? Many creatures have resistance to weapons that aren't "magic weapons".  A Magic Staff can be used as a quarterstaff, but (usually) doesn't have a bonus to hit (a "plus").  Is it considered a Magic Weapon for the purpose of damage resistance? Find $\lim_{n\to\infty}2^n\underbrace{\sqrt{2-\sqrt{2+\sqrt{2+\dots+\sqrt2}}}}_{n \textrm{ square roots}}$. Find $\displaystyle \lim_{n\to\infty}2^n\underbrace{\sqrt{2-\sqrt{2+\sqrt{2+\dots+\sqrt2}}}}_{n \textrm{ square roots}}$.   By geometry method, I know that this is $\pi$. But is there algebraic method to find this ?   Thank you. The new hot questions algorithm sometimes recurses The hot questions algorithm . I like the effects, since I see lots of new interesting stuff every day rather than waiting 6-8 weeks varying amounts of time for the list to update.  However, the new algorithm also has the interesting side effect of recursing the same question:    Of course, this is a world-shattering workflow-breaking unicorn-hating waffle-despising ERROR tremendously minor matter. But, if the SE devs have opportunity during their amazingly large amounts of free time, it might be nice to add a check for the current page before populating the hot questions list.
