What kind of moderation tools are available in Stackexchange to delete questions automatically that contain specified keywords or download links? It's been few weeks that I see someone making new accounts and posting a question with a similar content and one download link. I always flag it as spam, maybe few others do the same and question gets removed after few hours. Is there a better way to manage such spam posts? Example:
When flagging, there are two special case options: spam and rude or abusive.   What is spam, and when should I flag content as such? What is considered offensive, rude or abusive content? How does the spam flag differ from the rude or abusive flag? What is the effect of these special flags? When are these flags removed?
Extremizing sum and difference of lengths using triangle inequality We have three points $P=(2,3)$, $Q=(4,-2)$ and $R=(\alpha,0)$. We need to find the value of $\alpha$ such that:    Part 1: $|PR+QR|$ is maximized.  Part 2: $|PR-QR|$ is minimized.  I have  the solution for both. I have understood the solution for case 1 but not for case 2.  Case 1's solution :    Case 2's Solution:   I have understood case 1 completely but in case 2 why was there a need to take the image of point Q? I fail to understand this. Excel automatic hyperlinks SEO Removal Time? I was searching about removing the a domain/site being listed in Web Search Results (like, Google Search) and i found solution, .  I believe it will be the solution but what i still need to know is:   How long will it take to bring down my Website being listed from Search Engine Results? My case here is that I was writing something for school, and my teacher explained an error which I really can't see. She referred to articles about &quot;dangling participles&quot;, which was previously unknown to me. I find it hard to relate the examples I've found about it to my situation. So this is a text I've written and the bold part is where the problem arises: (You could read only the bold part if you please)  Wandering, and lost in his thoughts, there is a deep despair occupying the mind of this man. He is barely aware of his surroundings, except for those few moments when the loud blissful voices break through the protective barriers, developed by his immense sadness and grave frustration, into his mind. ”How can they all possibly be so happy?” he thinks to himself. Staring blindly, with his head low, as he walks in a slow pace, whispering ”Mary, Mary, my Mary,” over and over again. Yesterday was her funeral. She had passed away from a severe type of cancer, at a relatively young age. It was his wife. They had been together since high school and were greatly attached to each other. Having spent nearly half his life by her side, we cannot but imagine his grief. Indeed, he could hardly picture a life without her. So, alone he roams in the midst of all the seemingly incessant cheering and noises, drowned by his sorrow.  Her comments on that part was:  we is slightly out of place here – see my comment below These few sentences are about him and his emotions, so ‘we’ seems out of place. If the sentence starts: ‘Having spent nearly half his life by her side’, the reader expects it to continue: ‘he’. After all we have not spent half our lives by her side.  Is she right? If so, could anyone try to explain why? In a topological space, why the intersection only has to be finite? I was wondering if there is a reason why in the definition of a topologic space, the reunion of any collection of open sets is also an open set but the intersection has to be finite to be a set.  Is there because of the definition of an open set itself ? I have always seen it as a definition, but now I want to know why.  Thanks for your help. Smooth structure of embedded submanifolds /etc/shadow date of last password change—UTC or local time? man 5 shadow gives the following description of the third field in each line:  The date of the last password change, expressed as the number of days since Jan 1, 1970. The value 0 has a special meaning, which is that the user should change her pasword the next time she will log in the system. An empty field means that password aging features are disabled.  Does this refer to times in UTC or the local timezone? In particular, if I want to calculate comparable numbers using something like $(( $(date +%s) / 86400 )), do I need to pass date the -u option? I recently bought myself a pack of four YN560 IV's and a YN560-TX for my Canon camera, and apparently I got ahead of myself and didn't realise I should make sure the flashes support HSS.  I tried them out yesterday at home, and even on 1/128 and 1/250s on the camera, they were overexposing here and there. Unfortunately, I don't really have the space to move the flashes much further from my subject, so I was wondering if there is any way to trick them into HSS? I should mention that I also own a Canon 580ex II, which does support HSS. I was thinking I could perhaps use that mounted on the camera to trigger the Yongnuo's, but as far as I can tell that would render the 560-TX useless as the flashes can't be controlled wirelessly when in S1 or S2.  I guess I could buy an ND filter, but as I have lenses with differing sizes, this feels like more of a pain in the ass.  Is there any hack I can pull off here that you guys know of?  Thanks! Can someone help me figure out what this TiKZ code does? How is memory allocated for an implicitly defined multidimensional array in C99? How do I find out which dlls an executable will load? If I have a Windows executable, how can I find out which dlls it will load?  I'm just talking about which ones that will be loaded statically, not ones it might load dynamically with something like LoadLibrary. What is the difference between String.Empty and "" (empty string)? In what order should you do linear regression diagnostics? In linear regression analysis, we analyze outliers, investigate multicollinearity, test heteroscedasticty.   The question is:  Is there any order to apply these? I mean, do we have to analyze outliers very firstly, and then examine multicollinearity? Or reverse?    Is there any rule of thumb about this? How to choose which FaceTime number to call I have a friend with two iPhones, two different numbers.  When I call her with FaceTime audio, only phone A rings.  How can I call phone B?  The phones have two separate Apple ID addresses, but they are both set to receive Facetime calls on their 10 digit phone numbers.  I have both numbers listed in my contacts as 'Home' and 'Work' for the same person. Solving a six-degree polynomial of the form $ax^6+bx^3+g$. I read that it is not always possible to solve but from Wikipedia:      Some sixth degree equations, such as $ax^6 + dx^3 + g = 0$, can be solved   by factorizing into radicals, but other sextics cannot.   So how do you solve this? I've stumbled upon this equation where; $a = n^2$, $d=m^2n-2p^2$, and $g=m^4$. Where the $a,d,g$ corresponds to the above mentioned sextic-equation and $m,n,p$ are input variables. I apologize for that ton of variables in use, might cause some confusion. Is this possible using Galois Theory or by any other means? What makes a good entry level road bike? I've been riding a mountain bike for years, but I prefer to go longer distances on paved ground, so I think a road bike would be better. When I ask what is a good bike, I don't need brands or models - more like what components of the bike should I look for, and what should I avoid? Additionally, is it necessary to "go big or don't go at all" as far as spending - getting a real good quality road bike for $500 to a few thousand, or should I cheap out on a $100-200 road bike, as it is my first, then get a better one when I'm more experienced? Test to see when table is candidate for compression (row or page) Does anyone know a tool like this page  where one can determine if a table is a good candidate for row or page compression. Also I am trying to understand the benefits of compression. I have been reading about it, but still have these questions.  Will compression make more 8KB fit in the buffer cache? When does data become uncompressed i.e. in a select? will backups become faster? Is the reason that compression ads cpu overhead because e.g. inserts need to be compressed before the insert? Is there any good reason to compress tables without investigating how the tables is being used (i.e. static vs. volatile).  A colleague has started to compress many tables (page). I don't know the analysis behind this decision. I know we sometimes have resource semaphore waits during some peak hours. I actually don't think he knows what he is doing. I can see that our sos scheduler yield waits have gone slightly up. I think the compression is causing more harm and it seems that maintenance tasks overshoot more now (e.g. backups, checkdb...). I have seen some users show a picture of their network profile on the profile tab. How can I add this for my own account? Expanding a parent  to the height of its children I have a page structure similar to this:  &lt;body&gt;   &lt;div id="parent"&gt;     &lt;div id="childRightCol"&gt;       /*Content*/     &lt;/div&gt;     &lt;div id="childLeftCol"&gt;       /*Content*/     &lt;/div&gt;   &lt;/div&gt; &lt;/body&gt;   I would like for the parent div to expand in height when the inner div's height increases.  Edit: One problem is that if the width of the child content expands past the width of the browser window, my current CSS puts a horizontal scrollbar on the parent div.  I would like the scrollbar to be at the page level. Currently my parent div is set to overflow: auto;  Can you please help me with the CSS for this? Do AWS Reserved Instances need to be assigned to the instance? I have an RDS instance running of type db.t2.small.  I bought a reserved instance for 1 year of the same type, I paid the partial upfront rate.  Do I need to assign this subscription in some way to my existing instance to say 'This is the instance that is using the subscription' or does AWS just charge for the instance usage depending which instances you have running and whether an available subscription was active for it at the time which determines the running rate?  The reason that I ask is that I can't see any mention of the reduced rate on my AWS Billing area and it shows that I've used 17 hours of my reservation, but there isn't a row on my bill so far this month that indicates the new partial upfront rate that I should be charged for my instance.
