I'm trying to find if my database has a column named sort_method. I have had a look around the forums but don't seem to be able to find the right answer. My database has over 300 tables so manually looking for it is not an option.  I'm using phpMyAdmin - SQL query
I have 2-3 different column names that I want to look up in the entire DB and list out all tables which have those columns. Any easy script?
Minimum eigenvalue and singular value of a square matrix How to show that the relationship $\left | \lambda_{min} \right | \geq \sigma_{min}$ holds between the minimum eigenvalue and singular value of a square matrix $A \in \mathbb{C}^{n \times n}$? I'm having trouble editing this file on Windows 7:  C:\Program Files (x86)\CMake 2.8.7\share\cmake-2.8\Modules\FindJNI.cmake   If I edit it in Cygwin (vi) or TextPad, those two programs see the changes, so it's getting written to disk somewhere.  But if I "type" the file in a DOS cmd shell, it looks like the file hasn't been changed at all.  One thing I noticed is that in the cmd shell, the owner is Administrators, but in Cygwin's bash shell, the owner is Dan:  C:\Program Files (x86)\CMake 2.8.7\share\cmake-2.8\Modules&gt;dir /Q FindJ*  Volume in drive C is Windows7_OS  Volume Serial Number is 92CA-8707   Directory of C:\Program Files (x86)\CMake 2.8.7\share\cmake-2.8\Modules  12/30/2011  09:45 AM             1,480 BUILTIN\Administrators FindJasper.cmake 12/30/2011  09:45 AM             7,951 BUILTIN\Administrators FindJava.cmake 12/30/2011  09:45 AM            10,632 BUILTIN\Administrators FindJNI.cmake 12/30/2011  09:45 AM             1,669 BUILTIN\Administrators FindJPEG.cmake                4 File(s)         21,732 bytes                0 Dir(s)  132,524,654,592 bytes free   Dan@home /c/Program Files (x86)/CMake 2.8.7/share/cmake-2.8/Modules $ ls -al FindJ* -rwx------+ 1 Dan            None 10636 Jan 30 13:57 FindJNI.cmake -rwx------+ 1 Administrators None  1669 Dec 30 09:45 FindJPEG.cmake -rwx------+ 1 Administrators None  1480 Dec 30 09:45 FindJasper.cmake -rwx------+ 1 Administrators None  7951 Dec 30 09:45 FindJava.cmake   How can this be?  It's like there are two different files with the same name in the same directory. Is a business card necessary for a graduate student? I know some PhD students have their own business cards, but I don't know if it is a standard practice for PhD students to have their own business cards. I think a business card can be useful for networking in conference or collaborating with some industrial partners. So, is are business cards necessary for a PhD student or other graduate students attending conferences?

Proving a Composition of Functions is Bijective If I have $f:\mathbb{R}\rightarrow\mathbb{R}$ such that $f$ is onto and $f\circ f\circ f = f$, how can I prove that $f$ is bijective? I know that I only have to prove that it is 1-to-1 because I'm given the fact that it's onto, but how can I use the fact that $f\circ f\circ f=f$ to prove that it is 1-to-1?  Thanks! Is it possible to explicitly tell Stack Overflow the language of the code block you are including? Possible Duplicates:             Stack Overflow awesomely detects what language a code block is and syntax highlights it accordingly. But sometimes it fails.

Prove $3(x^2y+y^2z+z^2x)(xy^2+yz^2+zx^2)\ge xyz(x+y+z)^3$ if $x,y,z$ are positive real numbers,Prove:$$3(x^2y+y^2z+z^2x)(xy^2+yz^2+zx^2)\ge xyz(x+y+z)^3$$ Additional info:$\sum_{cyc}$ denotes sums over cyclic permutations of the symbols $x,y,z$.

Things I have done: Writing Left hand side in expanded form:$$LHS=3(\sum_{cyc}x^3y^3+\sum_{cyc}xy^4z+3x^2y^2z^2)$$ Right now I don't have good idea were to start(Is expanding and looking for AM-GM is good?).So any hint is appreciated.

Are all stormtroopers as poor soldiers as the ones in the movies? In the Star Wars films we consistently witness just how poor soldiers stormtroopers are. They show very sub-par marksmanship, crappy house searching tactics, and are easily fooled and defeated by Ewoks and Rebels.   That being said, I remember reading a character guide that defined stormtroopers as the very best of the best (best marksman, above average intelligence, etc.). So, in the realm of the Expanded Universe, does the mold that the movies set continue to hold true or are they just the exceptions to the rule? When abstract logic circuits get translated to the electrical equivilant, how are conversions from 0 to 1 handled? I've searched around and there's lots of good information out there, but I'm a bit of a n00b when it comes to the precise meanings of words like current, voltage, amplify, resistor, diode etc. So what at first presents itself as a simple explanation quickly turns into a wikipedia tabfest of ever increasing complexity. With that in mind please forgive my probably inaccurate use of these terms in this post.  The basic problem for me is that gates on a logic circuit appear to be creating power from nothing, which is impossible. For example imagine two NOT gates connected in sequence: To my uninitiated mind what seems to be happening is that the first NOT gate cuts the power to the second NOT gate, which responds by magically conjuring new power out of thin air and sending it on it's way. The only explanation I can come up with feels a bit redundant and absurd (That every single gate on the diagram is implied to be directly connected to a power source)  The closest I've come to an answer is something to do with changing the "signal" from "high" to "low" but again, I'm not familiar enough with the language. It still suffers from the same problem, if you've got a low signal how is it that a NOT gate can turn it into a high one without directly drawing on a power source?  To wrap up and present the question in all it's rookie glory: How do logic gates physically convert 0 to 1 without violating the law of conservation of energy?

How to close (kill) ssh ControlMaster connections manually A nasty integral of a rational function I'm having a hard time proving the following $$\int_0^{\infty} \frac{x^8 - 4x^6 + 9x^4 - 5x^2 + 1}{x^{12} - 10 x^{10} + 37x^8 - 42x^6 + 26x^4 - 8x^2 + 1} \, dx = \frac{\pi}{2}.$$  Mathematica has no problem evaluating it while I haven't the slightest idea how to approach it. Of course, I would like to prove it without the use of a computer. Is this an explicit form of a special function I fail to recognize?
