Why does Windows only show about 3.5 GB of my 4 GB of RAM?
Creating Users on secondary server in log shipping I have a production Server say ServerA I have setup log shipping to ServerB which is left in read-only mode. The purpose of this log shipping is to lower the load on production server for some expensive queries (painful reports).   Now if I have to create some logins using our domain accounts. I cannot do this because the secondary database is in standby mode.   I thought if I create these logins on Primary server it will be copied over to secondary server then the logs are restored there but this isnt the case.   I have done a lot of research online finding a way around to this. I found the following resources for this. I tried every method suggested in this articles but none of them seems to work.   1)   2)   3)   Has someone experienced the same issue? what did you do? Is there any way around for this issue? Any suggestions any pointer please. I want to create a simple figure where images are connected with arrows. Here is what I did:  \begin{tikzpicture} \node[](A) {\includegraphics[width=0.2\textwidth]{a}}; \node[right=1mm of A](B) {\includegraphics[width=0.2\textwidth]{b}}; \draw[-&gt;] (A) to (B); \end{tikzpicture}     But I want the arrow to start and end right at the images with no space between. How can I do that?

How to download packages from a command-line given repository? relation between $R^2$ of simple regression and multiple regression A very basic question concerning the $R^2$ of OLS regressions   run OLS regression y ~ x1, we have an $R^2$, say 0.3 run OLS regression y ~ x2, we have another $R^2$, say 0.4 now we run a regression y ~ x1 + x2, what value can this regression's R squared be?   I think it's clear the $R^2$ for the multiple regression should be no less than 0.4, but is it possible for it to be more than 0.7? Why was a moved question deleted? Moderator to whom deletion is attributed claims they didn't do it A  appears to have been deleted, and deletion is attributed to a moderator,  deleted by Sathyajith Bhat♦ 12 hours ago , however,  (however, they did previously (unsuccessfully) tried migrating it to another site in the network where they're also a moderator, but migration was rejected by another moderator, it was then on hold on webapps, and then the hold was removed, which was supposed to have been the end of it).  Can someone explain what's going on here?  And restore the question that clearly wasn't meant to have been deleted, was a HNQ, and has 75 votes on the question, plus 74 votes on the top answer, and 56 on second answer; and 19 on third?  There's a lot of links to this question, too, and now they're all broken, making SE look like a community hostile to a popular question ontopic for the site it was on. 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)? A word to describe "work that is ready to be done" Print numbered paragraph after title with Biblatex My question is related with Biber and Biblatex (latest versions). I need to quote the number of a paragraph of an old Christian text which is published within a book printed nowadays.   More clearly, I'm working with this Biblatex item (it's in Italian):  @INBOOK{Clemente1984Lettera,   author = {Clemente di Roma},   title = {Lettera di Clemente Romano ai Corinti},   year = {1984},   booktitle = {I Padri apostolici},   editor = {Quaquarelli, Antonio},   location = {Roma},   pages = {41-92},   publisher = {Città Nuova} }   I quote it in a common LaTex file with the BibTex key:  \cite[42]{Clemente1985Lettera}   With a humanistic Biblatex style, the final citation is:  Clemente di Roma, Lettera di Clemente Romano ai Corinti, in "I Padri apostolici", edited by A. Quaquarelli, Roma 1985, p. 42.  Anyway, I need to quote specifically the n. 2 of the letter of Clement, so I have to print this number just after the title "Lettera di Clemente Romano ai Corinti". So, I'd like to have this citation:  Clemente di Roma, Lettera di Clemente Romano ai Corinti, n. 2, in "I Padri apostolici", edited by A. Quaquarelli, Roma 1985, p. 42.  Now, I can find no Biblatex field to store the "n. 2" text, and no way to print it after the title. Of course, I could create a specific item in the bibliographic file in which the title field, or another one which is supposed to follow it, contains the "n. 2" indication. Anyway, this solution is very bad to me, because I should fill my archive with items of specific citations, and not of single titles.  What I'm looking for is what I've already implemented in the Bibfilex citations system (), which is moreover far less powerful that Biber: the possibility to add a pipe in the postnote of a BibTex key to separate a possible indication of a number of a paragraph, to be printed just after the title, from the pages of the volume. So a key like that  \cite[2|42]{Clemente1985Lettera}   should print   Clemente di Roma, Lettera di Clemente Romano ai Corinti, n. 2, in "I Padri apostolici", edited by A. Quaquarelli, Roma 1985, p. 42.  Anybody knows how to do that with Biber and Biblatex?  Thanks. Need a matrix to seventh power which is the identity but the original is not or the negative identity The question on the homework wants a $2\times2$ matrix $R$, but $R$ not equal to positive or negative identity, that when you raise to seventh power you get the identity.  $R^7=\operatorname{Id}$.  I thought it would have to be some ones and negative ones,  it no luck, then tried some ones and some $.5$.  Just using an online matrix calculator to do brute force.  We just started talking about eigenvalues with visual example, so assuming wouldn't need that since we have not talked about how to find them yet.  Any hints or ideas to get me back on track? Variations in the pronunciation of "the" Although there are rather simple rules determining the pronunciation of "the", native speakers quite often deviate from these rules (including, e.g., TV shows). According to the Longman Pronunciation Dictionary,     The EFL learner is advised to use [ðə] before a consonant sound (the   boy, the house), [ði] before a vowel sound (the egg, the hour). Native   speakers, however, sometimes ignore this distribution, in particular   by using [ðə] before a vowel (which is in turn usually reinforced by a   preceding ʔ), or by using [ði:] in any   environment, though especially before a hesitation pause. Furthermore,   some speakers use stressed [ðə] as a strong form, rather than the   usual [ði:].   My question is: when native speakers use [ðə] instead of [ði] before a vowel sound, do they do it on purpose or accidentally? If it is on purpose, how do they (typically) decide which pronunciation to use? What is a valid reason to use [ðə] before a vowel sound? SQL Server: Examples of PIVOTing String data Trying to find some simple SQL Server PIVOT examples.  Most of the examples that I have found involve counting or summing up numbers.  I just want to pivot some string data.  For example, I have a query returning the following.  Action1 VIEW   Action1 EDIT   Action2 VIEW   Action3 VIEW   Action3 EDIT     I would like to use PIVOT (if even possible) to make the results like so:  Action1 VIEW EDIT   Action2 VIEW NULL   Action3 VIEW EDIT     Is this even possible with the PIVOT functionality? How do I get the value of a textbox using jQuery? Given a file like this:  1,768,12,46576457,7898 1,123,435,134,146 2,345,6756856,12312,1311 5,234,567465,12341,1341 1,3245,4356345,2442,13 9,423,2342,121,463 9,989,342,121,1212   I would like to list all rows (in bash terminal) such that the value in column 1 appears at least twice (in column 1).

I downloaded it and unrared it with no problems, but it was full of .exe's instead of the intended contents (fonts) so I advised him to delete it immediately and not use.  I then proceeded to do the same, but the folder simply will not delete. Oddly the files went fine, and I never ran anything, but this is what I'm seeing:   Could not find this item  This is no longer located in C:\Users\This_User\Desktop. verify the item's location and try again.   I've tried the following things with no help:   Using "Unlocker" to Unlock and delete Using move on reboot and rebooting Using PendMoves (from sysinternals) and rebooting Elevating a cmd line, doing a dir /x to get the short name of the folder, and then del 'shortna~1' Moving the folder to a new folder and then trying to delete the parent folder   I'm on Windows 7 RTM, very fresh install. Any thoughts?  Update: Just to confirm, I've run Hijack this and half a dozen other malware detectors, and everything came back clean (no extra processes, no other obvious badness). Rebooting in safe mode didn't help either. Accidentally created directory named "~" (tilde) I managed to make a directory literally named ~.  (Apparently, Python's os.mkdir('~/something') does this.)  How do I remove it without nuking my home?  Also, if it helps, I have my real /home on a separate partition. And the duplicate ~ is located in (the real ) ~. 529 plan withdrawal penalties My son is a freshman this year.  We live in and he attends school in California.  We pulled out the first $ from our Utah 529 plan.  I had the money deposited in my account since I paid the registration and dorm &amp; meal plan.  Our friend has a son a year ahead and he has the exact same 529 plan.  He warned me that he got hit with a small tax penalty when he withdrew the money to his account and not to an account in his son's name.  I called the 529 administrator and they said it shouldn't matter either way.  Other online blogs agree.  They say the only difference is that my son would get the tax forms and have to file if it went to his account. Nevertheless, my friend did get a penalty.  Any clarity would be appreciated! SSH access to office host behind NAT router I would like to access the ssh port of my office linux host from home. Unfortunately the host is located behind a NAT router. So, the IP address is not publicly available. There is however access to another internet host (Server) which is unfortunately only non-root access. After a while of searching I do not find a suitable solution.  Following setup:   Office PC (linux, root access) behind NAT (IP not public) but full Internet access. Server PC (linux, no root access) static and public IP and full Internet access. Home PC (linux, root access) behind NAT (IP not public) but full Internet access.   Possible connections: Office PC --> Server &lt;-- Home PC  Not possible: Office PC &lt;-X- Server -X-> Home PC  Neither the Home PC, nor the Server can initiate access to the Office PC. But both the Office PC and the Home PC can initiate connections to the Server.  Reverse SSH tunnel not possible: I tried a method called reverse ssh-tunnel. Unfortunately this requires GatewayPorts on Server set to "yes" in /etc/ssh/sshd_config, where I have no root access.  In principle it should be possible:   0) On the Server I start a userspace program which listens on 2 ports (1 incoming, 1 outgoing)  1) On my office PC I run a another program which keeps a TCP connection open to the outgoing port on the server.  2) From home I connect to Server's incoming port.  There should be a standard solution for this out there.  What is the quickest and cleanest solution to solve this?  Frank I'm using listings and I want to extend a language with additional keywords for highlightning. I know there is an option morekeywords available, but that only works for a particular lstset declaration and I don't want to have to copy-paste all keywords into all listings. I've tried declaring the keywords as part of a command but that doesn't work (probably because the command is not expanded and I don't know how to fix that).  So is there any way of declaring a new language by copying an existing one and just adding more keywords?
