I'm seeing in GWT a bunch of request of removal of pages, which weren't submitted from someone in my organization. I'm referring to the tab under Google Index->Remove URLs. Does it include any user-requested removals? How does someone submit such a request? It allows me to cancel a request (which I didn't submit in the first place) how does that make any sense?
Take a look at the following screenshot I took from Google Webmaster Tools "Remove URLs" page:   None of these were performed by me or others who have access to GWT.  How do these removal requests happen without us doing any requests?  Why is that happening?  How to stop that or is there any point in stopping that?

Possible Duplicate:          I've been seeing that expression for over 10 years now. I've been trying to think what it's good for. Since I see it mostly in #defines, I assume it's good for inner scope variable declaration and for using breaks (instead of gotos.)  Is it good for anything else? Do you use it? On Travel-SE, there are currently  awarded. However, when one uses the search interface with views:2500, . The two numbers should be equal, and it's difficult to explain the difference with caching issues.   As the number of views is ever-increasing (as we all know, it's impossible to un-see things, unfortunately), this seems like a bug. Or perhaps I'm doing something wrong?  Also, some questions which should qualify don't appear on the search page. See , for example.  None of these questions are closed or deleted: views:2500 closed:yes and views:2500 deleted:yes return 0 results.  Eeeek? How to find and return a duplicate value in array Determining if trees within forest gaps are clustered using R? The attached dataset shows approximately 6000 saplings in approximately 50 variable sized forest gaps.  I am interested in learning how these saplings are growing within their respective gaps (i.e. clustered, random, dispersed).  As you know, a traditional approach would be to run Global Moran's I.  However, aggregations of trees within aggregations of gaps seems to be an inappropriate use of Moran's I.  I ran some test statistics with Moran's I using a threshold distance of 50 meters, which produced nonsensical results (i.e. p-value = 0.0000000...).  The interaction among the gap aggregations are likely producing these results.  I have considered creating a script to loop through individual canopy gaps and determine the clustering within each gap, although displaying these results to the public would be problematic.    What is the best approach to quantify clustering within clusters? Install windows 7 through virtual box I have a firewall with these simple rules:  iptables -A INPUT -p tcp -s 127.0.0.1/32 --dport 6000 -j ACCEPT iptables -A INPUT -p tcp -s 192.168.16.20/32 --dport 6000 -j ACCEPT iptables -A INPUT -p tcp --dport 6000 -j REJECT   Now, suppose I am using TCPDUMP like this:  tcpdump port 6000   And I have host 192.168.16.21 trying to connect to port 6000.  Will/should tcpdump output some packets coming from 192.168.16.21? Card example:   There are a lot of cards that use counter as a noun. I did some Googling but I'm just not clear on what I need to use for counters.  Are they physical things I can buy and if so, what is a good online resource?  Can I just make do with coins or something? How to get rid of blank pages in PDF exported from SSRS I have a two-page SSRS report. When I exported it to PDF it was taking 4 pages due to its width, where the 2nd and 4th pages were displaying one of my fields from the table. I tried to set the layout size in report properties as width=18in and height =8.5in.  It gave me the whole table in a single page of PDF, but I am still getting the 2nd and 4th pages blank.   Is the way I am doing it incorrect?  How else can I get rid of those blank pages? This is a canonical question and answer developed by the community to help address common questions.

Make sure only a single instance of a program is running Is there a Pythonic way to have only one instance of a program running?   The only reasonable solution I've come up with is trying to run it as a server on some port, then second program trying to bind to same port - fails. But it's not really a great idea, maybe there's something more lightweight than this?    (Take into consideration that program is expected to fail sometimes, i.e. segfault - so things like "lock file" won't work) IOS 5.1.1 Safemode problem I jailbroke my old iPod Touch 3rd Generation, with IOS 5.1.1, using the latest version of absynthe. It worked for several months, but then it randomly stopped. It went into safe mode, but the touch screen wouldn't work. It showed the lockscreen, but nothing worked at all, except for the physical buttons. The only way to reboot is to follow the same steps as DFU mode (Hold power button 3 sec, then home button AND power for 10, then just home for 8)... However, it always boots right back into Safe mode.  I had to restore, and once rejailbroken, it worked fine, until I installed SBsettings. Then it did the EXACT same thing, and I had to restore and re-jailbreak AGAIN! The other day, I finished installing ALL of my extensive list of tweaks, and got it to about where I wanted it, when lo and behold, it booted to safe mode again. I have spent so much time on this, and I do not want to do it again. Does anybody here have any knowledge on the topic? Is there a program I can run from my computer to manually control the device or kick it out of safe mode? Is there some other method of doing this? I am looking for any solution OTHER than restoring. I have done that several times.  Also, I know the problem isn't with my jailbreak. It worked for several months before, then one day stopped. Now, it has the problem within a day of rejailbreaking, OR instantly if I install SBsettings. I re-installed the jailbreak, and applied the new one as well, and that didn't work. I have given up, and don't want to go through the painful process of restoring, rejailbreaking, and re-installing all of those tweaks again.  Also, because I can't get into my iPod, I can't provide a list of tweaks. I would if I could, but it just can't happen unless I can get in there. Open Attachment on Create of Child Record Tilde (~) File in Macintosh Directory Last night I discovered what looks like an unusual file named "~" (tilde) in the root of my "Macintosh HD" directory on my MacBook.    Finder reports the file is 2.2MB in size, of kind "TextEdit.app Document", and was created on 22nd January 2014 (so about a month ago).  I haven't noticed any operational issues with OS X or it's applications.   I haven't yet touched the file but would obviously like to remove it.  I am very conscious that '~' is a special alias to the user home directory and thus I would appreciate any recommendations in removing the file in a safe manner that isn't likely to nuke my home directory or screw up the operation of applications or OS X. I don't know whether to delete or rename and whether to use Finder or the command line.   It's entirely possible that I created the file by accident since I've recently been drafting and running various shell scripts that use the ~, user home alias.

Reputation and inbox notification shows up again after refresh I have set up my site with sample pages and data (lorem ipsum, etc..) and Google has crawled these pages. I deleted all these pages and actually added real content but in webmaster tools, i still get a lot of 404 errors Google trying to crawl these pages. I have set them to "mark as resolved" but some pages still come back as 404.   Furthermore, I have a lot of these sample pages still listed when i do a search of my site on Google. How to remove them. I think these irrelevant pages are hurting my rating.   I actually wanted to erase all these pages and start getting my site being being indexed as a new one but I read it's not possible? (I have submitted a sitemap and used "Fetch as Google.") How to pass javascript value to controller..? I want to pass the java-script value to controller.I am using repeat on VF page.

Hidden2.value is same as hidden1.value + some addition subtraction.i dont know how to pass that value. Can someone me sort out this.  Thanks Prove that if W is a subspace of a finite dimensional vector space V, then dim(W) ≤ dim(V). My attempt at a solution:  Proof  Given a vector space $V$, let $S={v_1,...,v_n}$ be a basis for $V$. Consequently $\dim(V)=n$. Now given $W$, a subspace of $V$, it will be shown that $\dim(W)\le \dim V$   First, consider the case where $W=${0}. Then $dim(W)=0 \le\ n$,   Subsequently, consider the case for $W=V$. Then it follows that $dim(W)=dim(V)=n$.  Finally, consider the case where $W \subset V$ and without loss of generality assume $v_n \notin W$. Let $T={v_1,...,v_k}$ where $k\lt n$ be a basis for the subspace W. Now, since S is a basis for V, for every $v_i \in S$,  $c_1v_1+...+c_nv_n=0$ has only the trivial solution, thus none of the vectors in S can be expressed as linear combinations of the other vectors in S. It follows that the set T is not a basis for V as $v_n$ cannot be generated from T. The $dim(W)$ is given by the number of vectors in the basis. Therefore, $dim(W)=k \lt n$  Therefore, it has been shown that if $W \subseteq V$ then $dim(W) \le dim(V)$
