IDE: Microsoft SQL Server Management Studio  Mistakenly I have cleaned a table data using  delete from table tblBookData   and now it has cleaned that table, please tell me is there any way to get back that data?   If yes than please tell me the process, as I have studied there is a way to get back data if we have not closed the session.
I mistakenly deleted around 2,000,000 records from a remote SQL Server 2008 table.  The server is not granting me access to the backup files on the server side.   Is there any way to get back these records?
I am running Ubuntu 12.04 on an IBM ThnkPad T42.  I just installed Gnome and Cinnamon but I am still using Unity.  The only problem is that in dash when I search for any application they don't appear.  I don't see recent applications either.  I fixed it by running unity --reset but the next time I turned on my computer it was broken again How can I enable Hardmode? What items do I need to make my world Hard Mode? How to make shortcuts on Ubuntu 17.10? I am starting to learn using blender, and at some point I managed to do something to the 3D view camera.  Usually the camera orbits around an object, but now the rotation seems to happen (atleast very close to) around the "camera's origin". Neither the input setting in "User Preferences", the pivot point selection nor Ctrl-Alt-Shift-C (as suggested on some forum) do anything to the issue. Computing $\lim_{n\rightarrow \infty} \frac{1+\sqrt{2}+\sqrt[3]{3}+\cdots+\sqrt[n]{n}}{n}$. I have a problem with the calculation of the following limit. \begin{equation} \lim_{n\rightarrow \infty} \frac{1+\sqrt{2}+\sqrt[3]{3}+\cdots+\sqrt[n]{n}}{n} \end{equation} I do not know where to start! Thank you very much Is there a statement whose undecidability is undecidable? We know there are statements that are undecidable/independent of ZFC. Can there be a statement S, such that (ZFC $\not\vdash$ S and ZFC $\not\vdash$ ~S) is undecidable? Does causation imply correlation? Correlation does not imply causation, as there could be many explanations for the correlation. But does causation imply correlation? Intuitively, I would think that the presence of causation means there is necessarily some correlation. But my intuition has not always served me well in statistics. Does causation imply correlation? How do I change the mode of perspective? I'm working on a scene that, currently, is much more convenient when the view is.. not the correct perspective. There's a word for this, but I have no idea how to phrase it and my tries to look it up has all come up with weird results. (usually directions on how to make your view point from a certain direction) This has probably already been answered here, so please bear with me; I just cannot find anything that has to do with the problem I'm having. I drew a photo to make it easy: (excuse my crappy mouse-drawing skills)  Thanks! How can I fix "unbalanced brackets" in my data tag? A friend of mine, native EN speaker, told me that the following is correct written like this:      We met on the 1st of June.   Is that really true? I cannot see any reference that these are used in written text. I made my first sculpt model and I used a mirror modifier. But then I applied the mirror modifier, because I got a strange edge on the mirror line in sculpt mode. Now I modeled it, but it still mirrors the model, what in the beginning was good, but sometime I want to do asymmetrical things.  What did I wrong? Many thanks for your help!! Happy modeling :D What is the meaning of the term "thread-safe"? Does it mean that two threads can't change the underlying data simultaneously? Or does it mean that the given code segment will run with predictable results when multiple threads are executing that code segment? S tabular with alignment No CUDA and GPU option I have Blender 2.73a with AMD Radeon 3100 Graphics. I saw  on how to make cycles render faster. It says when I go to User Preferences> System> Compute Device, It has no CUDA option, which means there is no GPU option. How can I fix this? Possible to have 2 unity launchers? Empty signature file after i.gensig in GRASS I'm trying to make a supervised classification in Grass 6.4.3 under Linuxmint 16.  After digitizing the training areas, I transformed them from vector to raster. Then I've done the following: just in case: g.region rast=train_area_2013_03_05_raster@PERMANENT,2013_03_05_toar4@PERMANENT  then  i.group group=group subgroup=sub_group input=2013_03_05_toar4@PERMANENT,2013_03_05_toar5@PERMANENT,2013_03_05_toar3@PERMANENT  and   i.gensig trainingmap=train_area_2013_03_05_raster@PERMANENT group=group@PERMANENT subgroup=sub_group signaturefile=superv_class  but the resulting signature file, only contains one character: "#".  The output of i.gensig in the console is the following:  Finding training classes... 3 classes found Calculating class means... Calculating class covariance matrices... Signature 1 not invertible Signature 2 not invertible Signature 3 not invertible i.gensig complete.   Obviously if I try: i.maxlik group=group@PERMANENT subgroup=sub_group sigfile=superv_class class=results_class  I obtain the following error message:  ERROR: Unable to read signature file &lt;superv_class&gt;   I've been searching, but I couldn't find the solution.   I've tried: this   My problem is similar to this: . But here, there's no solution suggested. As in this case, I also used i.cluster to generate an unsupervised signature file and i.maxlik reads this perfectly well.   there's another similar question, but again, with no solution...  What does Signature X not invertible means?  Any idea? Thanks for your help! Apply a string replacement on the citation as returned by \cite If this is a duplicate question, please point to the right way, but the similar questions I've found here haven't been sufficiently similar. Suppose I estimate the model $$Y=\alpha + \beta X + u$$  and find that $\beta&gt;0$. However, it turns out that $X=X_1+X_2$, and I suspect $\partial Y/\partial X_1 \ne \partial Y / \partial X_2$, and in particular, that $\partial Y/\partial X_1 &gt; \partial Y / \partial X_2$. So I estimate the model $$Y=\alpha + \beta_1 X_1 + \beta_2 X_2 +u$$and find significant evidence for $\beta_1,\beta_2&gt;0$. How can I then test whether $\beta_1&gt; \beta_2$? I considered running another regression $$Y=\alpha +\gamma(X_1 - X_2) + u$$ And testing whether $\gamma&gt;0$. Is this the best way?  Also, I need to generalize the answer to many variables, i.e. suppose we have $$Y=\alpha + \beta^1 X^1 + \beta ^2 X^2 + \dots + \beta^nX^n + u$$ where for each $j=1,\dots,n$, $X^j=X_1^j+X_2^j$, and I would like to test for each $j$ whether $\partial Y/\partial X_1^j \ne \partial Y / \partial X_2^j$.  By the way, I am primarily working in R. So when I got Steam working offline I had 26 games listed in my library but only 2 installed. Recently I brought a bunch more so I want to update my library on my Offline PC with the full list that's on my Online Laptop.  I thought that all I would need just copy the data from userdata/[ID]/config/localconfig.vdf however when I do the number goes down to 2 (the number of games I do have installed) and also the OST I got with Monster Monpiece doesn't appear. When I restore just that file the list and the music listing returns.  So what do I need to copy over from my Online Laptop to the Offline PC to update the list of games in the library? Trying to get my head around the commutator subgroup. This is an excercise from Artin's Algebra:  Let $C$ be the commutator subgroup of $G$. Prove that $G/C$ is abelian.  Here is what I've done:  Let $xC,yC \in G/C$ then $xyx^{-1}y^{-1}C = C$ since $xyx^{-1}y^{-1}$ is a commutator hence belongs to $C$. But then $xyC = yxC$ so $xC$ and $yC$ commute in $G/C$. This can be done for any elements, so $G/C$ is abelian.  This seems somewhat surprisingly short. Is that all there is to it?   Regards
