While reviewing suggested edits, I can across one for  which, as the tag wiki currently states, is clearly the result of a typo.  There are no questions tagged with this, and the tag edit was approved nullifying my attempt to disapprove it.  Neither is there any way to flag the edit for moderator attention.  Is there a way for this to be removed, and if so, could somebody with sufficient power do so?
If a tag wiki becomes inaccessible due to a tag being eliminated, is the data destroyed? Or would it be able to be recovered by just recreating the tag?  On Gaming we had one tag for a particularly difficult case that a wiki entry was written for. There has been some debate as to what we should keep the tag as, which has led to the only instance of the tag being renamed a few times and eventually left on a new tag. The nightly script eventually cleaned out the original tag, and the wiki is inaccessible. So would I be able to retrieve this by reverting to the original tag, or is a rewrite of the wiki necessary?
Is it possible to generate electric energy from the radiation of radioactive materials I wonder if it is possible to generate electric energy from the radiation of radioactive materials like nuclear waste? If it is then wouldn't that also mean that it could be used as an energy source for a very long time since the radiation takes a long time to decay? in -> inner  out -> outer / (outter?)  What is the history or set of rules behind why 'inner' doubles the 'n' but 'outer' doesn't double the 't'? I need to get a nice picture about how electron moves around nucleus? I find concept of probability and orbitals quite difficult to understand? What is the highest obtainable resolution of FREE elevation data in the UK? Logging individual application network usage in Windows 7 There are many answers here detailing programs that will monitor and log internet usage for a pc, but I need that usage to be logged and broken down, detailing which applications consumed that data.  I've noted there are several that give a real-time feed of each application's data usage (NetLimiter, Win7 Resource Monitor), but I can't find one that will log such data.  Anyone know of one?  Need to track down which program is using up a friend's bandwidth! Flag post that is already in low quality review queue - any effect? Let's say I see an answer that should not have been one and I flag it as Not An Answer (NAA). On this site I have plenty of reputation and am able to use the Low Quality (LQ) review queue and cast delete recommendation votes.  Of course raising such a flag on a still virgin post brings it to the LQ review queue, but what happens if I flag a post on the main site that is already in the respective review queue?  Is my flag simply useless in that case? I doubt it would be the same as casting a delete (recommendation) vote from the queue. And when I somehow manage to find that specific post in the review queue later, it's locked down for me, because I have already cast a flag. So was that flag without any effect?  Based on how I currently guess the system works, I proposed two alternative solutions to improve the system in my feature request . They were first part of this question, but I decided to split the question from the feature requests. I kust realized that some other PC is also getting assigned a IP address (DHCP Lease) from my modem. I am sure this is not one of the PCs in my home.  My modem was using WEP security. I know WEP is far less secure and WPA is better, but this actually is a borrowed modem, and I did not know that WEP was used.  I immediately did the following : On My Modem    Changed the encryption mode from WEP to WPA   Changed the password   After this I do not see the intruder PC on the DHCP list.  On my Mac:     Changed the permissions on the public folder to "everyone - no access"   Turned off "File Sharing" in System Preferences (But I would want to turn it back on sometime)   My mac is the one that is always on, Both the admin user and the user I normally use are password protected.  Is the above sufficient? Should I do something more?  Also, is WPA security sufficient? Should I take other steps? See these sentences:     See there, it seems that someone is inside the house. OVER   See there, it seems that someone is in the house.   Another example:     The doctors found two bullets in his body. OVER   The doctors found two bullets inside his body.   Certainly, both are interchangeable, aren't they? But in the bullet's example, the second one looks natural. I'm not sure why. Is it something that bullets were first out and then they went inside? But if that's the case, someone is in the house is also okay. That person too was out first! I am running the latest version of X3 Terran Conflict (3.1) and after about 30 min - 1 hour it's memory usage goes well above 2 GB.  I only have 4 GB of ram, running Windows 7 64 bit.  As a result of X3 using more ram than is available, my hard drive starts paging and makes the game and other applications become unusable.  I have to restart the game.  Is anyone aware of this issue or how to fix it and is there any way in Windows or through some tool, to limit how much memory is given to the game?  Is this a bug in the game? Can this even be fixed?  I'm using some mods but I doubt any of them are causing this as they are simple mods like adding a tractor beam etc. Find all values of a for which $\{v_1,v_2,v_3\}$ form a basis for ${\bf R}^3$ I was setting up up android-studio referring to .

I did a fresh installation of Ubuntu 16.04. Probability of lim sup, lim inf for sequence of random variables. Maybe this is extremely simple, but i havent found a specific answer for this online.  For a sequence of independent continuous random variables $X_n$ ,$n=1,2,3,...$ , all with the same probability density function $f(x)&gt;0$ for all real $x$, and a specific real number $b$, what do the following events mean in simple terms and what is the probability of each?  a)$\lim_n\sup\{X_n \gt b\}$ b)$\lim_n\inf\{X_n \gt b\}$ c)$\lim_n\sup\{X_n \le b\}$ d)$\lim_n\inf\{X_n \le b\}$ Electrons have spin 1/2, and as they are charged, they also have an associated magnetic moment, which can be measured by an electron beam splitting up in an inhomogeneous magnetic field or through the interaction of the electrons's magnetic moment with an external magnetic field in spectroscopic measurements.   On the other hand, a photon is neutral - how can one measure its spin if there's no magnetic moment? How do we know it has spin 1? If two ends were a certain "length" apart were they therefore at rest (or at least rigid) to each other? How to format a USB flash drive? In Windows there is a straightforward "Format" option in a flash drive's right-click pop-up menu. Where's that in Ubuntu? Why does this formulation of Choice not follow from the Comprehension Schema? One of my Fellows asked me whether total induction is applicable to real numbers, too ( or at least all real numbers ≥ 0) . We only used that for natural numbers so far.  Of course you have to change some things in the inductive step, when you want to use it on real numbers.  I guess that using induction on real numbers isn't really possible, since $[r,r+\epsilon]$ with $\epsilon > 0$, $r \in \mathbb R$ is never empty.  Can you either give a good reason, why it isn't possible or provide an example where it is used? How to make a file (e.g. a .sh script) executable, so it can be run from a terminal What is the joint distribution of $Z=\min(X,Y)$ and $I_{Z=X}$? Assume that $X$ and $Y$ are independent random variables with $X \sim \exp(\lambda)$ and $Y \sim \exp(\mu)$. It is impossible to obtain direct observations of $X$ and $Y$. Instead, we observe the random variables $Z$ and $W$, where $Z = \min\{X,Y\}$ and $W =1$ if $Z=X$ and $W=0$ if $Z=Y$.  How to find the joint distribution of $Z$ and $W$? Let $G$ be a finite abelian group, then $G$ has a subgroup of order $n$ if and only if $n\mid G$.  Proof: by Lagrange if $H\leq G$ then $|H|$ divides $|G|$ so this proves one of the implications.  We prove the other implication by strong induction on the order of $G$, for primes this is just Cauchy, so we can take these like base cases. Now let $n$ be a proper divisor of $|G|$, take $p$ a prime in the factorization of $|G|$ (instead of $|G|$ is should be $n$, I had made a mistake when typing the first time), then by cauchy there is an element $x$ of $G$ of order $p$, since $G$ is abelian $\langle x\rangle$ is normal in $G$ so we can look at the quotient group $G/\langle x\rangle$, this group has order $\frac{|G|}{p}$, now take a prime $p_1$ in the factorization of $\frac{|G|}{n}$. By induction the quotient group has a subgroup $E$ of order $G/pp_1$ now look at the preimage of $E$ under the natural homomorphism from $G$ to $G/\langle x\rangle$, it is easy to see this is a subgroup of $G$, we call it $I$, consider the restriction of the natural projection to $I$, this is a surjective homomorphism from $I$ to $E$ with kernel $\langle x\rangle$ so by the first isomorphism theorem $I/x\cong E$ so $\frac{|I|}{|\langle  x\rangle|}=|E|\implies  |I|=\frac{|G|}{pp_1}{p}=\frac{|G|}{p_1}$ Notice $\frac{|G|}{p_1}$ is a multiple of $n$ since $p_1$ was in the fatorization of $\frac{|G|}{n}$. So by induction $I$ has a subgroup of order $n$ which is also a subgroup of $G$.
