I have a blog which can be accessed at  http://mysite.com/blog/   I would like to access it like this because I think it looks cleaner  http://blog.mysite.com   I did some reading on domains, subdomains, and redirects and have created a subdomain with the desired URL and re-directed it to the blog path.  Is this a common set up? Is there a better way to accomplish what I want to do?
We have more than one content management system (eCommerce) running on our site and we want to know would it be wise to separate these systems and run on their own server for better performance, easier to manage and better for security, but our concern is the SEO impact.  Is it better to run site.com/this-is-our-other-platform/ or this-is-our-other-platform.site.com?
The trigonometric ratios of an angle greater than $90^\circ$ are equal to the supplementary angle's ratios.  I'm just clarifying this, but the ratios don't actually exist for angles greater than $90^\circ$ right? (since by definition these ratios are of a right angle triangle). Is it just mathematical custom to assume the ratios of an angle greater than $90^\circ$ to be equivalent to its supplementary angle's ratios? For convenience? Can we switch terminals at Heathrow (LHR) for shopping only? I have a very large folder that I am trying to create a tar archive of. The issue is I don't have enough extra free space to store the entire archive so I want to create say 100-200GB chunks of the archive at a time and transfer those individually to cloud storage. I need to be able to control when new chunks are created so my HDD doesn't fill up but all of the commands i've found to create split tarballs always create it all at once, in the same directory. The closest solution I found was from  but all the responses base the archives on number of files, not size which is important for my use case as my file sizes are unevenly distributed. What is the difference between metonymy and synecdoche? Increasing the maximum number of enumerate environments? I have to admit, I didn't even know spoilers were supported until today, but really bugs me that spoilers just look like empty block quotes before you mouse over them.   Is this a spoiler or just a long empty block quote? I can't tell right away, so it would be really nice if there was some indication of which one it was so I didn't have to push my mouse all the way over to it. What can I say, I'm incredibly lazy.  vs.         I suppose the author should include something that says 'Spoilers below:', but it would be nice if there was some other indication of what it was. Is there a way to determine the respective canonical status of Tolkien's Middle-earth related works? It is almost always difficult to determine the canonicity (if that's a word) of different works within a fictional universe, but the problems are even more complicated in regards to Tolkien's Middle-earth/Arda related material.  It is safe to say that LotR, the second edition of The Hobbit, and probably the published Silmarillion are canon.  But even the published Silmarillion is, in large part, the work of Christopher Tolkien, although to a lesser degree than it is the work of his more famous father.    When we look at the rest of the corpus, things become even more opaque.  Unfinished Tales contains different versions of the same stories.  The same is true, in even greater degree, of The History of Middle-earth.  These volumes might be considered an almost equal endeavor on the parts of Christopher and J.R.R Tolkien.    Is there a tentative canon of Tolkien's Middle-earth related works, and if not, is it possible to create one?    With such a large body of work, of varying degrees of canonicity, it would be very helpful to have something like the now-outdated levels of canon associated with the Star Wars universe, ranked by a series of letters.  Has anyone put together such a system for Tolkien's Middle-earth related works? Could a website force the browser to go into fullscreen mode? I want to run a psychological study for which participants have to look at large images.  The experiment is done on the web and therefore in a browser window. Is it possible to tell the browser to go into fullscreen, for example on button press?  I know there is the possibility to open a fixed-size popup window. Do you think this would be a feasable alternative? And if, what would be the best way to do it? Are there elegant ways of detecting a popup-blocker, to fallback and run the study in the original browser window.  The main concern is that the participants of this study are not familiar with technical details and should not be bothered by them.

How can I forward message from a specific log file like /www/myapp/log/test.log with rsyslog client to remote rsyslog server? This log file is outside of the directory /var/log. How to prove the property of the Lemoine point of a triangle? From Wolfram , I know there is a Lemoine point of triangle, also called symmedian point, the sum of squared distances of this point to all the three sides is algebraically minimum.    How to prove such a property? Relation between real roots of a polynomial and real roots of its derivative I have this question which popped in my mind while solving questions of maxima and minima. First Case:Let $f(x)$ be an $n$ degree polynomial which has $r$ real roots. Using this can we say anything about the number of real roots of $f'(x)$?  Second Case:Suppose, $f(x)$ has all  $n$ real roots. Then will all of its derivatives also have all real roots?  Also, if any of its derivatives do not have all real roots, then will $f(x)$ also have not all real roots? If the above is true then what about its converse?  Comment Case:For the third case:Suppose f'(x) is a 5 degree polynomial with 3 real roots.Then f(x) will be a 6 degree polynomial.(correct me if I am wrong).What are the possible no. of roots that f(x) can have(3,4,5 etc.?).Basically I am asking for an example.Also it would be great if you follow all cases with an example like in the 4th case. Prove $\sum\limits_{i=2}^{n}\frac{1}{(i-1)i}$ = $\frac{(n-1)}{n}$ using induction. I need to prove $\sum\limits_{i=2}^{n}\frac{1}{(i-1)i}$ = $\frac{(n-1)}{n}$ using induction. I am getting stuck midway through the inductive step.   Here is what I have:  $\forall n\geq 2$, where $n\in\mathbb{N}, P(n)$ is the statement "$\sum\limits_{i=2}^{n}\frac{1}{(i-1)i}$ = $\frac{(n-1)}{n}$".  Base case:  $\sum\limits_{i=2}^{2}\frac{1}{(i-1)i}$ = $\frac{1}{2}$ = $\frac{(2-1)}{2}$ so $P(2)$ is true.  Inductive assumption: Assume $P(n)$ is true. Need to show $\sum\limits_{i=2}^{n+1}\frac{1}{(i-1)i}$ = $\frac{((n+1)-1)}{(n+1)}$.  $\sum\limits_{i=2}^{n}\frac{1}{(i-1)i}$ + $\frac{1}{n^{2}}$ = $\frac{(n-1)}{n}$ + $\frac{1}{n^{2}}$  = $\frac{n(n-1) + 1}{n^{2}}$ = $\frac{n^{2}-n+1}{n^{2}}$  I got stuck here and tried working backward from $\frac{((n+1)-1)}{(n+1)}$, which gives me:  $\frac{((n+1)-1)}{(n+1)}$ = $\frac{n}{(n+1)}$   Any suggestions on what to do next or where I may be going wrong? I want to propose for a Persian version of Super User (I will explain why later) so I want to create a proposal in Area 51, but this means non-English question and answers, Is this OK? P.S: This may be a question for other non-English proposals too. Update: The main question is: How can non-English site proposals pass the Commitment phase? How can the English community support non-English proposals? You can find some information in  about the Stack Exchange 2.0 Site Creation Process (specially Commitment phase):  How does this thermometer work? Intuitively, if Jon Skeet says that he’ll participate in the Sock Puppet Stack Exchange, that commitment is a better sign that the site will succeed than if we get a commitment from a random Internet user who has never participated in Stack Overflow. Sure, they’re both wonderful people, I’m sure, but Jon Skeet has proven that he likes to participate in Stack Overflow so it’s a good bet that he’ll participate in SockExchange, too. .... we’re going to require a selection of existing users with certain badges and reputation that proves that they’ll participate. For instance (and I’m making these numbers up), we might require that a site get at least 100 commitments from people with the Teacher badge, at least 20 from people with the Enthusiast badge, and at least 50 from people with a reputation of 1000 or more on some of our sites. How do I remove 'Places' entries from the Nautilus sidebar? I want to remove Videos and Music from the left side panel. But, I can't seem to find the option to do so. How do you do that? TeX editor with line-spacing preferences Number of onto functions I get that some spells are "especially swift" to cast and thus have a casting time of "Bonus Action". But is there any reason I couldn't cast such a spell as my Action?   Does it make a difference if the idea is for the one spell to be cast all by itself on a turn or if the desire is to use another Bonus Action (possibly a spell) on the same turn? Do different "Picture styles" affect RAW output? I was  the manual of my camera (Canon 50D, but I am sure that each DSLR offer the same kind of functionality, albeit I don't know the exact names adopted) and noticed the issue of Picture styles which I had overlooked in my first reading.   In short I think that they are a collection of various calibration settings (more or less enhanced colours, things like that...). Those that are available on my camera are:   Standard Portrait Landscape Neutral Faithful  Monochrome 3 user definable modes.   These styles are so important to deserve a direct button just under the LCD screen of the camera (I guess this is useful for simplifying the use of the camera in the basic modes as opposed to manual / less automated ones).  And now for the question:   These settings obviously affect the appearance of the picture "as it comes out of the camera". But given the raw file I assume that they are all equivalent, a style is not applying a destructive transformation to the raw data, isn't it?  Shooting raw, is there a reason to favor one of these styles (Neutral?) over the other? Up to now I have been using Standard.   As a bonus (don't know if it deserves a separate question, in which case I will ask it again), what is the difference between Neutral and Faithful? What apps are people using to record voice meetings on the iPad? I'm looking to do some light recording of voice conversations and field recordings on my iPad using the built in microphone.    seems to be the obvious Apple solution, but is too heavy for my needs. By the time I set up a new project, turn off the metronome, etc..., I find myself wishing I just had  running on my iPad.   I don't mind paying for the app, but wondered what people are using for both light voice recording as well as longer and more numerous recording / light editing where some tagging and filing might be possible.
