I'm egyptian holder shengen visa single type valid from 13 August till 7th sep  I would like to travel to greece from 13 August to 18 after that wants to apply for turkish e-Visa can I apply and enter Turkey as my shengen is used and single entry but will be valid but someone told me single entry means that once u went out of shengen area means expired even if its valid for one month I need yr help  Please confirm
I got a UK visa for one month (restricted validity). It expires on November 4. Pakistani citizens are eligible to apply for a Turkish e visa if they have a valid UK visa. I want to visit Istanbul for a couple of days - from October 31 to November 2. Would I be eligible to still apply for an e visa?   My visa is for single entry. It's valid from October 4 to November 4.
Why this JSFiddle does not work There is no such thing as magnetism? Here's an interesting "proof" that there is no such thing as magnetism. I know the answer but I love this so much I had to ask it here. It's a great way to confuse people!  As we all know, $$\nabla \cdot\vec{B} =0$$ Using the divergence theorem, we find $$ \iint_S \vec{B} \cdot \hat{n} \, dS = \iiint_V \nabla \cdot \vec{B} \, dV = 0$$ Since $\vec{B}$ has zero divergence, there exist a vector function $\vec{A}$ such that $$\vec{B} = \nabla \times \vec{A}$$ Combining the last two equations, we get $$\iint_S \hat{n} \cdot \nabla \times \vec{A} \, dS = 0$$ Applying Stokes' theorem, we find $$\oint_C \vec{A} \cdot \hat{t} \, ds = \iint_S \hat{n} \cdot \nabla \times \vec{A} \, dS = 0$$ Therefore, $\vec{A}$ is path independent and we can write $\vec{A} = \nabla \psi$ for some scalar function $\psi$. Since the curl of the gradient of a function is zero, we arrive at: $$\vec{B} = \nabla \times \nabla \psi = 0,$$ which means that all magnetic fields are zero, but that can't be!  Can you see where we went wrong? I am running an application through gdb and I want to set a breakpoint for any time a specific variable is accessed / changed. Is there a good method for doing this? I would also be interested in other ways to monitor a variable in C/C++ to see if/when it changes. How can I stop Nautilus from dereferencing symlinks? I use symbolic links to tidy my home folder. This works well in the terminal, since the links create the illusion of normal folders:    In Nautilus, however, the links behave more like , immediately teleporting me to their target:    This is particularly troubling when¹ I later want to navigate "up" to the parent folder, as it strands me somewhere outside of the tree I've carefully tidied.  How can I make Nautilus show symbolic links as normal folders, like the terminal does?  Details   Nautilus did not dereference symlinks in Ubuntu 12.10:   Maybe this new behavior is just a bug? I'm not sure how to tell. Here's what I know:   It's not on the . I've skimmed the  and didn't see anything related. The Nautilus mailing list archive . I received no response from about 120 idlers when posing the question on the GNOME IRC channel. A change was made in Nautilus 3.6 to .  ¹ This is an example. A workaround for this particular scenario does not constitute an answer to my question. Since people seem to be interested in discussing it, though:   Using the Back button is not a suitable workaround; it does not always take me to the parent folder. You can navigate up by pressing Alt+Up. The desired behavior in this example is for "up" to navigate to the parent folder of the symbolic link. The current behavior is to navigate to the parent folder of the target of the symbolic link. POSIX compliant way to redirect stdout and stderr to a file I am trying to write a script which is POSIX compliant, so it can run on any *nix system (Debian, Fedora, CentOS, AIX, Arch... ALL of them). When it comes to redirection, I am rather confused on what is supported by POSIX and what is not.  If I redirect ls -l file missingfile &amp;&gt; out.txt this works perfectly in bash. The line from stderr complaining that missingfile doesn't exist, and the permissions output from file, are both in out.txt. However, I believe this is only working because these shells support more than just POSIX standard operators. Upon researching this question I've come across conflicting answers.  , for example, seems to imply that &amp;&gt;, &gt;&amp;, &gt;&gt;&amp; and &amp;&gt;&gt; are non-standard operations. However,  explicitly states that some-program &gt; some_file 2&gt;&amp;1 is POSIX compliant. Does this mean that the &gt;&amp; operator (using digits for stderr &amp; stdout) is POSIX compliant whereas using &amp;&gt; to auto redirect both stderr and stdout to a file is not POSIX compliant? Or are both &amp;&gt; and &gt;&amp; not POSIX compliant / POSIX compliant (one of these two people are wrong)?  I considered just avoiding the &amp; sign completely and using ls -l file missingfile &gt;out.txt 2&gt;out.txt however this comes with its own issue. Running the ls command this way causes the shell to open two file handles for out.txt, both pointing to offset 0 in the file. So when ls looks for these two files, one of the messages gets clobbered.  What one would expect ls -l file missingfile &gt;out.txt 2&gt;out.txt to output:  -rw-r--r-- 1 blah blah 0 Jun  3 13:18 file ls: cannot access 'missingfile': No such file or directory   What is actually output:  -rw-r--r-- 1 blah blah 0 Jun  3 13:18 file le or directory   What is the best way to redirect both stdout and stderr to a file in a POSIX compliant fashion? How to show that a Banach space $X$ is reflexive if and only if its dual $X'$ is reflexive? Is there a secular, non vulgar alternative to "for heaven's sake"? I know for heaven's sake, for Pete's sake, for God's sake and for Christ's sake. All of those, however are religious references. The only non-religious equivalent phrases I know are for fuck's sake and its variations. Are there any non-vulgar, non-religious alternatives? I am very used to the general construct of for X's sake and am looking for something along the same lines that I could use in cases like  C'mon, it's just a scratch for X's sake! That's not even true for X's sake!  It does not need to also be applicable as a general exclamation of frustration (Oh, for chrissake!) but that would be nice. Basically, I'm looking for a synonym for the &quot;Oh come on!&quot; sense of for fuck's sake rather than the Oh shit! one.  EDIT: Since this has gotten quite a bit of attention, I would like to urge those who answer to read the entire question, not just the title. I am not just looking for polite swearwords but for something that can be used in the example phrases above. I'm trouble with exercise 1.8 of Carroll's Space-Time and Geometry:     If $\partial_\nu T^{\mu \nu} = Q^\mu$, what physically does the spatial vector $Q^i$ represent? Use the dust energy momentum tensor to make your case.    First of all, since the momentum energy tensor of dust $T^{\mu \nu}=\rho U^\mu U^\nu$ is symmetric, one has the energy-momentum conservation law $$ \partial_\nu T^{\mu \nu} = \partial_\nu T^{\nu \mu}  =0.$$ A vector $Q$ is constant in any frame related by a Lorentz transformation, while this isn't the case for the components $Q^\mu$. But here $Q=0$ and hence $Q^\mu=0$ also for every component $\mu =0,\cdots,4$?   Even if a straightforwardly apply the equation: $$ Q^i = \partial_\nu T^{i \nu} = (\partial_\nu \rho) U^i U^\nu + \rho(\partial_\nu U^i)  U^\nu + \rho U^i(\partial_\nu  U^\nu ),$$ doesn't seems to yield something...   Is my first reasoning right ? Otherwise: can someone give me a hint ?  Thanks Finding an expression for $\tan (a+ b + y)$ which involves only $\tan a, \tan b,$ and $\tan y$. How to find this ?   I'm stuck at $1$ and how to $1$ to change the tangent associated with a,b or c.  I meant this ,everybody.  $\frac{tan(a)+tan(b)+tan(y)−tan(a)tan(b)tan(y)}{1−tan(a)tan(b)−tan(a)tan(y)−tan(b)tan(y)}$ Exponent and abelian groups What exponent $e$ can guarantee the group to be abelian?

Also I'm changing the URLs to user friendly URLs /product.aspx?id=100 to /product-name/100.  All my pages are indexed by search engines and the site has already been online for 6 years.

What is $\int_0^1\frac{x^7-1}{\log(x)}\mathrm dx$? Is there a convenient way to import a schema into Oracle 11gR2 using a single new or different tablespace than where the data originated?  As an example, I have exported BLOG_DATA from OLDDB, where all user data is stored in the USERS tablespace.   On NEWDB, I would like to import the BLOG_DATA schema, but store the user objects in the BLOG_DATA tablespace, created specifically for this user.   I have created the BLOG_DATA user, created the BLOG_DATA tablespace and set it as the default tablespace for that user and added an appropriate unlimited quota.  CREATE TABLESPACE blog_data DATAFILE SIZE 1G;  CREATE USER blog_data IDENTIFIED BY secretpassword DEFAULT TABLESPACE blog_data QUOTA UNLIMITED ON blog_data;  GRANT connect,resource TO blog_data   The schema was exported from OLDDB with something like  exp blog_data/secretpassword@OLDDB file=blog_data.dmp    After reading Phil's excellent answer below, I found myself wondering:   Since data has no other place to go than the default tablespace - the only tablespace the user has a quota on - will this effectively force imp to put all user objects in that default tablespace?  imp blog_data/secretpassword@NEWDB file=blog_data.dmp   Would this then place the entire blog_data schema in the blog_data tablespace on NEWDB? Is there any reason why this wouldn't work or that I would run into problems with certain objects etc?  update:  I did a quick test and found this to be the case. Imp places objects in the default tablespace for that user, provided it can't place it in the original tablespace (eg. the tablespace does not exist). Full explanation:   Still, I suppose that using Data Pump like Phil suggests might be the preferred option.

Imported from this uservoice item: "May I have a glass of water" vs. "Can I have a glass of water": which is better, "may I" or "can I", when asking for something? What is the correct sentence when asking for something like while flying asking for a glass of water :     May I have a glass of water     or      Can I have a glass of water How can I explain to a non-native why the plural of a noun isn't used adjectivally? How can I explain to a non-native speaker that while this is correct:     The felling of trees.    And this is also correct:     tree felling   This is not:     *trees felling   To a non-native it seems very reasonable that since many trees are being felled and given that the felling of trees uses the plural, the inverse form would also use the plural and become trees felling.  To a native speaker such as myself, the latter is very obviously wrong, but I couldn't figure out how to formalize this into a rule that a non-native can understand.
