I formatted my MacBook main drive some months ago and, in order to not lose data, I created a .dmg image of the hard drive before the formatting procedure and saved it to an external device.   Then, some days ago, I started a kind of data restoring, coping most of the backup files back to the main drive.   Now, I would like to check if all these mentioned files have really been copied back to my Macbook. Due to this, I am looking for an application theoretically able to analyze the files (in particular, their name, hash, etc.) contained in my external drive and find corresponding files on my Macintosh hard drive; if a  corresponding file is not found, the file should be highlighted. If a similar application actually exists, can you suggest it to me?  If there is not an application with the features above explained, can you suggest me a brief Bash script or AppleScript able to do that? I'm not familiar with both these languages, but I have a little Batch scripting background and I was thinking about some statements - e.g. the for loop, md5, etc. - which generate a filename plus MD5 checksum list for both drives, and which find correspondances. What about this? Can you suggest me some examples?     Note: This is not the same as . The new data structure on the main drive is a bit different compared to the previous one, which is stored in the external drive. Due to this, a standard folder/volume comparison with a dry rsync run is not exactly what I am looking for.
I'd like to copy files from one external drive to a network connected drive. I want to make sure that there are no errors.  I know of MD5 hash files that I see for large single files that are download from the internet. I also know that I can use the terminal to 'diff' the two sets of files.  However, I'm looking for a piece of software that could confirm that all the files in the file structure have been copied by the finder completely, or a piece of software that would do the copying for me and confirm that all the bits are exactly the same.  The files are video related - and are often over a TB in size (not in one file - complex multi-folder nested files)  I'm fine if there is a terminal command that can do the copy and compare for me as well. (although being able to see the amount of time left on a copy is a very nice feature... additionally, I want to make sure I get ALL of the file - resource forks and all)
"Whether" Vs. "If" How to enable iptables (instead of firewalld) services on RHEL 7 and Fedora 18? The newest fedora has firewalld as new firewall aplication. I liked old iptables services. I want them back but have no idea how to do that. I have tried :  systemctl disable firewalld.service systemctl stop firewalld.service systemctl enable iptables.service systemctl enable ip6tables.service systemctl start iptables.service systemctl start ip6tables.service   But it does not work! Didn't find any help on wiki or google.  Disabling firewalld work ok, but when I'm trying to enable iptables.service I get:  systemctl enable iptables.service Failed to issue method call: No such file or directory How to connect to a MS Access file (mdb) using C#? $\sqrt{c+\sqrt{c+\sqrt{c+\cdots}}}$, or the limit of the sequence $x_{n+1} = \sqrt{c+x_n}$ Getting Windows 7 admin account password?

In bibliography, how to print the page in my text where I cited certain paper? How to get, for instance,  [19] S. Roth and M. J. Black. Fields of experts: A framework for learning image priors. In IEEE Conf. on Computer Vision and Pattern Recognition, 2005. 1, 2, 7, 8  where the last numbers (1, 2, 7, 8) are the pages where I cited the paper in MY TEXT?  This would be like a reversed reference, or a index for bibliography. How can I fix an out-of-focus blurred photo in Photoshop? How can I fix this picture?  Somebody else took this picture and well he wasn't able to do it very well, and it's blurred.    I have photoshop Prove that $1+\frac{1}{3}+\frac{1\cdot 3}{3\cdot 6}+\frac{1\cdot 3\cdot 5}{3\cdot 6 \cdot 9}+.........=\sqrt{3}$ Prove that $$1+\frac{1}{3}+\frac{1\cdot 3}{3\cdot 6}+\frac{1\cdot 3\cdot 5}{3\cdot 6 \cdot 9}+.........=\sqrt{3}$$   $\bf{My\; Try::}$ Using Binomial expansion of  $$(1-x)^{-n} = 1+nx+\frac{n(n+1)}{2}x^2+\frac{n(n+1)(n+2)}{6}x^3+.......$$  So we get $$nx=\frac{1}{3}$$ and $$\frac{nx(nx+x)}{2}=\frac{1}{3}\cdot \frac{3}{6}$$  We get $$\frac{1}{3}\left(\frac{1}{3}+x\right)=\frac{1}{3}\Rightarrow x=\frac{2}{3}$$  So we get $$n=\frac{1}{2}$$  So our series sum is $$(1-x)^{-n} = \left(1-\frac{2}{3}\right)^{-\frac{1}{2}} = \sqrt{3}$$  Although I know that this is the simplest proof, can we solve it any other way someting like defining $a_{n}$ and then use Telescopic sum.  Thanks. Start Mathematica without the menu bar? What is the meaning of p values and t values in statistical tests? After taking a statistics course and then trying to help fellow students, I noticed one subject that inspires much head-desk banging is interpreting the results of statistical hypothesis tests.  It seems that students easily learn how to perform the calculations required by a given test but get hung up on interpreting the results.  Many computerized tools report test results in terms of "p values" or "t values".  How would you explain the following points to college students taking their first course in statistics:   What does a "p-value" mean in relation to the hypothesis being tested?  Are there cases when one should be looking for a high p-value or a low p-value? What is the relationship between a p-value and a t-value? Consider an irreducible but possibly periodic Markov chain on a finite state space with transition matrix $P$. We know there exists a unique stationary distribution $\pi$. If the Markov chain were aperiodic, we would have $P^n_{ij} \to \pi(j)$ as $n \to \infty$. This fails if the chain is periodic, but we have convergence of the Cesaro averages: $$\frac{1}{n}\sum_{k=1}^n P^k_{ij} \to \pi(j) \text{ as } n \to \infty.$$ Can anyone point me to a reference that states this fact? Every reference I've seen only considers convergence for aperiodic chains, or "fixes" periodicity by considering a lazy version of the chain. Alternatively, is there a simple way to obtain this result using the result for aperiodic chains?

I've been trying to install 12.04 for a while now, I'm running on Windows 7 and I already made the partition (it's dynamic). I've tried booting from a disc and also the Windows installer. I haven't tried used any repair-boot programs or anything. Every time I tried to load from either, I get an error:  command=C:\windows\sysnative\bcdedit.exe /set {03f9077f-661f-11e1-845a-d08b36406c3d} device partition=U;  retval=1  stderr=An error has occured setting the element data.

If it is simply due to the fact of it being a dynamic partition, someone please help. If it is more extensive, anyone with details on possible solutions or definite ones please express them. Where is the "Manipulate Centers Only" button in Blender 2.8? I have looked just about everywhere on the Internet and I can't find the answer to this question. Where the hell is the "Manipulate Centers Only" button in Blender 2.8???? It's the the double arrow icon here:    I seem to have enabled it somehow and I can't scale or rotate my object. Why is "No new release found" when upgrading from a LTS to the next?
