Preventing domain controller from adding A/AAAA for domain root
Active Directory: Is it required that the "A" record for a domain point to a Domain Controller?
I was doing a very simple search:  grep -R Milledgeville ~/Documents   And after some time this error appeared:  grep: memory exhausted   How can I avoid this?  I have 10GB of RAM on my system and few applications running, so I am really surprised a simple grep runs out of memory. ~/Documents is about 100GB and contains all kinds of files.  grep -RI might not have this problem, but I want to search in binary files too. Old Sci-Fi book with skin crystalizing disease and characters with psi powers Is there an idiom for people who boast too much? SSL certificate for a public IP address? I just tried buying a Comodo Positive SSL but it was rejected due to not supporting a public IP address, but instead they only support a domain name.  Does anyone know any SSL certificate provider that supports public IP address instead of a domain name?  My company has a dedicated server hosted with a web hosting company, which is used for running a bugtracker for multiple projects (for multiple clients). Since it's only used for a bugtracker, we don't need a domain name (our clients access it by typing the public IP in their browser). I am trying to find a story where a children's nursery turns into a jungle I read this short story(I believe it was under novella length, but I could be mistaken) a while back, and I am trying to identify the title for a friend.   Plot:      Parents(male and female) get a computer aided/holographic nursery for their children. The mother becomes increasingly agitated as the children withdraw more. The children are barely even featured in the story, and the ending concludes with lions possibly eating the parents.   Publishing date: Years ago.   Tech level: Seemingly functional AI, not much more. We have a group of three characters: The lawful good paladin (acolyte), the lawful good fighter (soldier) and the chaotic good druid (criminal). All try to help NPCs in need, won't fight between themselves, but of course have different alignments and personalities. The druid is greedy, but otherwise a good guy. This brought up the question for our group whether greed can be considered a contradiction to having a chaotic good alignment? I understand it as "acting upon what is good, but having your own understanding of 'good'". But I am not sure if the PC being is played 'wrong'.   How do you determine if a given action is in line with a PC's alignment? And should the GM intervene if a PC is played differently that his/her alignment indicates?  Example: There is a Chaotic Good druid with a criminal background. The druid attacked caravans who destroyed his homeland, which he was protecting as his druidic duty, to make way for faster trade routes. Thus he made a name of himself and soon had quite a pile of goods in his territory. The thieves guild caught wind of that and made a deal with him to smuggle wares through his territory as long as they won't hurt the wildlife. So far, seems like a reasonable match between criminal and CG.  Upon opening a chest in a dungeon the druid found a magic chainmail and a bag filled with 420gp. As he was the only one next to the chest, he turned around and told his two comrades there were 360gp in the chest, keeping an extra 60gp to himself without them knowing. Later after finishing a task for the mayor the druid and the paladin persuaded him to give them 550 instead of 500gp, while the fighter was drunk outside. The druid told the paladin to keep his share of those 10% extra, as a gift for always being successful on those charismatic tasks. This was done to check out the personality of the paladin. He accepted without a second of doubt and didn't even contradict when the druid told him not to tell the fighter anything about the extra.   I am now confused about whether this is just unlawful or also not good, and if so what should I as DM do about it?

I took the example at the url  to get a black board style presentation.  This template includes a short script which uses a random-generator to randomly scatter dust-trails on the black background to mimic chalk traces (see MWE below).  The thing is that parallel to that, I am also using overlays to uncover my slide layout by layout. The script is executed each time I am using a layout command which slows down the compilation quite substantially. I am not so familiar with control statements in latex, so here is my question:  How can-I modify this script for the background to be refreshed only when the slide is over, and not after each layout command?  Remarks:  1) I am using the Augie font, but I didn't included it in the MWE so that it can be compiled more easily  2) In case, it should make a difference I am also using the \begin{textblock*} \end{textblock*} environment from the textpos package to position text on the slide.

Thanks in advance,  Yannick Let $\mathbb R$ denote the set of all real numbers. Find all function $f: R\to \ R$ such that   $$f\left(x^2+f(y)\right)=y+(f(x))^2$$   It is the problem. I tried to it by putting many at the place of $x$ and $y$ but I can't proceed. Please somebody help me. I asked a question  but, rather stupidly, added extra information after it had been answered.  My additional question is this: I have a table with varying lengths of words. I want to encircle different groups of cells, including diagonals.

Then the quotient space $X/\sim$ is homeomorphic to the unit circle $S^1$ via the homeomorphism which sends the equivalence class of $x$ to $\exp(2πix)$.   I understand relations, equivalence relation and equivalence class but quotient space is still too abstract for me. This seems like a simple enough example to begin with.  I understand (sort of) the definition but I can't visualize. And by this example and others, there is a lot of visualizing going on here! torus, circles etc. I gave a quick answer to part of  which had not been covered by previous answers, trying to clarify the reason you would say time of decoding but not decoding’s time. I said it was ’s usually indicates possession, but of course there were several counterexamples that would have occurred to me after a moment’s consideration, and these where helpfully supplied:   Britain’s climate two days’ time  a day’s work  the sun’s rays   I am still of a mind to say that possession of some sort is what allows the ’s. Even though the sun does not have title to its rays, they do belong to the sun. Now, at the risk of duplicating the original question and/or being pigheaded, I am curious as to why time of decoding but not decoding’s time is correct, if not for the reason I gave. Crash course on algebraic geometry with view to applications in physics Could you please recommend any good texts on algebraic geometry (just over the complex numbers rather than arbitrary fields) and on complex geometry including Kahler manifolds that could serve as an informal introduction to the subject for a theoretical physicist (having in mind the applications in physics, e.g. in the string theory)?   What I want for a moment is to get some informal picture of the subject rather than being dug up into the gory details of the proofs and lost in higher and higher layers of abstraction of commutative algebra and category theory. The texts I have found so far are all rather dry and almost completely lack this informal streak, and all of them are geared towards pure mathematicians, so if there exists something like "Algebraic geometry for physicists" and "Kahler manifolds for physicists" (of course, they would probably have different titles :)), I would greatly appreciate the relevant references. What changes after peer review but prior to final submission are acceptable for a conference paper? Show that function $f$ has a continuous extension to $[a,b]$ iff $f$ is uniformly continuous on $(a,b)$ Let $E \subset F \subset X$ and $f:E\rightarrow Y$. We say that the function $g:F\rightarrow Y$ is an extension of $f$ if $g(x) = f(x)$ for all $x \in E$.   Let $f: (a, b) \rightarrow \mathbb{R}$. Show that $f$ has a continuous extension to $[a, b]$ if and only if $f$ is uniformly continuous on $(a, b)$.   $(X,d)$ is a metric space.  Hint: To prove $\Leftarrow$ start by showing that $f$ maps Cauchy sequences to Cauchy sequences. Then how should you define $g(a)$ and $g(b)$?  The $\Rightarrow$ part of the proof was quite simple, but even with the hint, the other way seems a bit difficult. Doesn't the first part of the "hint" follow from the way we defined $f$? If so, how do I prove this? Help/Hints appreciated! Lost USB BlueTooth Dongle for Keyboard and Mouse I lost my USB bluetooth dongle (from HP) which I used for a wireless keyboard and mouse. They came together in a set when I bought my last HP computer.  Are the keyboard and mouse useless now? or will any bluetooth dongle allow them to work? If I can just buy a new one - any recommendations on a replacement (good price, and perhaps works with Windows and Ubuntu out-of-the-box?   Forgive me if this is an easy question. I'm just not that familiar with wireless mice/keyboards. Find the value of : $\cos x \cos 2x...\cos 999x$ given that $x=\frac {2\pi}{1999}$ Given $x=\frac {2\pi}{1999}$  Find the value of $$\cos x \cos 2x \cos 3x ...\cos 999x$$  So I tried expanding $\sin {2000x}=2\sin 1000x \cos 1000x$  Then rewriting  $\cos 1000x= \cos {(999x+x)}$   No luck so far. Trying to prove that $H=\langle a,b:a^{3}=b^{3}=(ab)^{3}=1\rangle$ is a group of infinite order. I'm trying to prove that the following group has infinite order: $$H=\langle a,b\mid a^{3}=b^{3}=(ab)^{3}=1\rangle.$$  Currently I'm checking on some cases using the relations, but my problem is the reducibility for large products.  Naively I started to check that $ab$ is different than $1,a,b$ and then $ba$ than $1,a,b,ab$, just to understand $H$ in some extent.   Now I'm wondering about some more effective method to prove that $|H|=\infty$, I'm tempted to look for an injection from some group of infinite order into $H$, but I'm still stuck.  More than asking for a solution I'd rather appreciate some hints or thoughts about it. Thanks a lot. How to keep VLC player in minimized mode? I'm using VLC media player which can play almost all kinds of audio and video formats. While listening to audio, I keep VLC in minimized mode and can work on other windows. But when I select to listen video songs mixing with audio songs, VLC is maximizing itself to play every video song in the playing list, which is really annoying in the middle of work.  So how can I keep always VLC player in minimized mode while playing a list of songs mixed with audio and video songs? VirtualBox Toolbar is hidden! How to show it?
