I have a polygon with a North_America_Lambert_Conformal_Conic coordinate system and a point shapefile which had a WGS 1984(DD) coordinate system.   I defined projection and projected both of them to North_America_Lambert_Conformal_Conic coordinate system. The two shapefiles do not overlay. If checked in the screen shot of ArcGIS 10.2, only one of the layer appears (whichever I have zoomed to).  Can someone please guide me on how I can get this to shapes to line up or overlay?   My intention is to do a spatial join on them so that I can count some point features within the polygons.
I put 4 different layers into my ArcMap document, but only one of them will show up on the map! I should be seeing the other 3 layers as well. When I do a Zoom to layer, I can see one layer, but I cannot figure out how to make the other 3 show up at once on top of each other.  Before I opened ArcMap, I used ArcCatalog where I right-clicked 3/4 of the shapefiles and  clicked Properties &rarr; Coordinate system &rarr; Import and then clicked on my Trees layer, which has the coordinate system I want the other 3 to have. But when I opened ArcMap the 4 layers did not overlap, nor could I move them above or below each other.
Is there a way to switch the mesh selection mode by a shortcut? I find myself frequently needing to rename different files with mv that are in deep directories:  mv /a/long/path/to/a/file.txt /a/long/path/to/a/file.txt.bak   But I don't want to retype the full path name. Is there a quick shorthand or alias that I could use? I.e.:  $ mv /a/long/path/to/a/file.txt file.txt.bak $ ls /a/long/path/to/a/file.txt.bak a/long/path/to/a/file.txt.bak   (note: this is for straightforward, single file renames in different directories at different times, not for ) Wrong math symbols with XeLaTeX and LuaTeX after TexLive update I just updated my TeX live installation (tlmgr update --all) and now I get some wrong symbols in math mode if I use XeLaTeX or LuaTeX. This MWE for example  \documentclass{standalone} \begin{document} $. + , - / $ \end{document}   produces the following output:    I suppose it is a bug in the new Latex2e version from 2016/02/01. Any ideas how to fix this?    EDIT:  Adding \usepackage{fontspec} produces a different output. But it is still not perfect. I installed vsFTPd for running an FTP server on  (Wheezy). I checked the vsFTPd version was 2.3.5, and I configured it like so:  listen=YES local_enable=YES write_enable=YES chroot_local_user=YES pasv_min_port=15000 pasv_max_port=15200 allow_writeable_chroot=YES   I followed these articles for solving this problem:       And many others on Google and forums, but my problem was not solved.  NOTE: I have solved this problem on  (Precise Pangolin), but that solution does not work on Debian 7.3.  I really mixed up on it?! Should we sign-then-encrypt, or encrypt-then-sign? Frequently, we want to send messages that are (a) encrypted, so passive attackers can't discover the plaintext of the message, and (b) signed with a private-key digital signature, so active attackers can't make Alice think that a message came from Bob when it didn't. Is it better to (a) generate the digital signature from the (hashed) plaintext, and then encrypt a file containing both the plaintext message and the digital signature? Or is it better to (b) encrypt the message first, and then generate a digital signature from the (hashed) encrypted file? Or (c) combine encryption and public-key digital signatures in some other way? A closely related earlier question (  ) seems to focus on symmetric-key MAC authentication. As , Do the same issues with (symmetric-key) MAC-then-encrypt apply to (public-key) sign-then-encrypt? How do I restore .bat files association with the system (make them run when double-clicked)? Is there a way to arrange windows within the same application in the taskbar of Windows 7?

Is there exist a function defined on the real or complex numbers that, restricted to the integers, is equal to the factorial? Double dual mappings $\newcommand{\Hom}{\operatorname{Hom}}$Let $U,V$ be vector spaces. Denote the dual space of $U$ with $U^\intercal$ and the dual mapping of a linear map $\Phi$ be $\Phi^\intercal$. Define the double dual embedding on $U$ to be $\iota_U:U \to U^{\intercal\intercal}$. ($u \in U, f \in U^\intercal$) $$ \iota_U(u)(f) = f(u) $$     If $\Phi \in \Hom(V,U)$, then $\Phi^{\intercal\intercal} \circ \iota_V = \iota_U \circ \Phi:V \to U^{\intercal\intercal}$   Proof: Let $v \in V, f \in U^\intercal$. Then $$ \iota_U \circ \Phi(v)(f) = f(\Phi(v)) $$ but how do I show that $$ \Phi^{\intercal\intercal} \circ \iota_V(v)(f) = f(\Phi(v)) $$ ? Death in SAO before Kayaba announcement I was wondering if in the novel we knew about some deaths occurring before Kayaba announcement. I remember that in the anime, Kirito plays a bit with Cline before realizing that the log off option has disappeared. Then all the people are summoned to the city and learn about the fact that if they die in the game, they also die in real life.  I don't remember any players dying before the announcement in the anime, except for those who are not waking up and their relative pulling off their NerveGear thus causing death, but maybe in the light novel, some guys died without even knowing it just while being defeated by a mob (which seems awful for me).  Do we know about some players dying before that while thinking they are still in a normal game? I recently put a bounty on a question regarding the . I did this as the only two answers on that page are not satisfactory and I wish to encourage a tractable answer.  I am concerned that when the bounty period expires, if I do not select an answer for the bounty that it may be awarded automatically to one of these speculative and unsatisfactory answers. How might I prevent that? I could put an answer of my own stating "no satisfactory sources are available" and award the bounty to that, however I feel that there should be a better way.  I stress that I put the bounty on the question specifically because the current answers are not satisfactory and I do not want to award them. How to include a document into another document?

My friend is a native Chinese speaker and this is the sort of plural thing that trips her up. How is this explained? I tried to find this question somewhere else on here, and found a couple that were similar to it -- but all the answers seemed pretty convoluted, and I think it was surprising to me because I just imagined that SQL would have a way easier way to do this.  Essentially, I'm using a GROUP BY to group two values on top of each other.

Solving a Diophantine equation with a large solution Test for convergence of the series $\sum_{n=2}^\infty\frac{1}{(\ln n)^{\ln n}}$ Could I have a hint for testing the convergence of the following series please?  $$\sum_{n=2}^\infty\frac{1}{(\ln n)^{\ln n}}$$  Edit  The integral test does not work because $\int_1^n\frac{1}{(\ln x)^{\ln x}}dx$ has not an elementary primitive.
