Trouble figuring out some attack/defense formulas. What should I change?
How to develop RPG Damage Formulas?
I believe there's a way to find the kth largest element in an unsorted array of length n in O(n).  Or perhaps it's "expected" O(n) or something.  How can we do this? Is it possible to dual boot two OS's at the same time? Is it possible to dual boot two OS's at the same time?  For example: I'm currently dual booting Ubuntu 11.04 and Windows 7. Ubuntu is running on a single 500gb HDD, Windows 7 is running on 1TB RAID 1 mirror. To switch between the two OS's, a reboot is required. Is it possible to switch between the two OS's without a reboot?  NOTE: I'm fully aware of the capabilities of VirtualBox and VMWare Player - I use both. Please don't answer "Use Virtualization!"  EDIT: If this is not possible can you share why it's not possible? To me, it doesn't seem like it would be that difficult. Keep in mind that my vision is unencumbered by knowledge! The anime Elfen Lied is notorious for its one of a kind OP, featuring the mesmerizing theme song Lilium composed by MOKA and performed by Kumiko Noma, as well as sequences of art porn, a homage to Austrian symbolist painter Gustav Klimt. The idea to pose the characters as in Klimt's artworks came, as far as I know, from director Mamoru Kanbe, who continued this idea in the OP of Sora no Woto. (In my humble opinion, the OP of Sora no Woto is rather bland, and seriously, Klimt with Kalafina?)  This is a self-answered question and a modest attempt at unraveling the sources of and the symbolism represented in Elfen Lied's OP scenes. Other answers and/or suggestions are welcome. Text spirals with TikZ I just ran across this, and I'm curious about whether it can be replicated in TeX...    Ideally one would have the spiral getting tighter and tighter as one got to the centre, as in    I know TikZ has the ability to fit text along a path, but I'm not sure how one might make text get smaller and smaller.  The closest I can find is , but that uses manually inserted font commands.  Edit: I got what I wanted using mwibrow's answer: I'm looking for specific, real cases in which a causal relationship was inappropriately inferred from evidence of a correlation.   Specifically, I'm interested in examples that meet the following criteria:   Existence of the causal relationship was accepted as fact widely enough to have notable effects (on public policy, discourse, individual decisions, etc.). The link was inferred solely on the basis of correlative evidence (perhaps along with the existence of a coherent but unproven causal mechanism).  Causality has been objectively falsified or at least called into serious doubt.   The two examples that came to mind for me aren't quite ideal:   Sodium intake and blood pressure: As I understand it, it has since been determined that salt intake only increases blood pressure in sodium-sensitive individuals. The existence of a valid causal relationship (although not quite the one that was originally accepted) make this example less compelling. Vaccines and autism: I may have the background wrong, but I believe this link was surmised on the basis of both correlations and (fraudulent) experimental evidence. This example is weakened by the fact that (fake) direct evidence existed.   Note: I've seen this similar question:    My question differs primarily in that it focuses on notable, real-world examples and not on examples in which a causal link is clearly absent (e.g., weight and musical skill). Execute vs Read bit. How do directory permissions in Linux work? In my CMS, I noticed that directories need the executable bit (+x) set for the user to open them. Why is the execute permission required to read a directory, and how do directory permissions in Linux work? New navigation doesn't appear to alert of question changes when watching a tag I am watching the  tag on Stack Overflow. My filter looks like this:    I do not receive notification of new questions. Previously I'd get notifications like this:    This notification does work when watching the  page of Meta.   Are notifications only active for a certain set of filter options? If so, what are they? If not, can we get them back when watching pages other than the main page? Prevent text selection after double click Extending the User model with custom fields in Django What's the best way to extend the User model (bundled with Django's authentication app) with custom fields? I would also possibly like to use the email as the username (for authentication purposes).  I've already seen a   to do it, but can't decide on which one is the best. Future Simple and Future Perfect I've read  about Future Simple and Future Perfect, but I still can't understand the exact usage of these two tenses. Is there any diffrence between the following?     I will do my homework by 6 p.m.   I will have done my homework by 6 p.m.       I will do my homework after school   I will have done my homework after school   Also, I've checked the word 'by' in  and there're some confusing examples:       By the time (that) this letter reaches you I will have left the country.   Can I use 'By the time (that) this letter reaches you I will leave the country' instead? I have a mathematical problem with the following formula. The goal is to transform this equation to have a seperated real and imaginary part. I have already done this with several other equasions, but for this particualar one I don't know where to start.  I dont expect you to do the complete work of transforming for me, it would already be very nice if you could give me a hind on how you would start.  Thank you in advance!  C||RLC      This is my current progress:    My question is:  How can I get rid of the imaginary part jωC2*R?  When the denominator is completely real I can just split up the formula and have an imaginary and a real part. Is there any method to close connection similar to  for  in WordPress?  Is it not necessary to close connection for global $wpdb? Why gpedit and the corresponding registry entries are not synchronized? Meaning of convolution? I have a Lenovo Ideapad with pre-installed Windows 8.1 In order to install Ubuntu I disabled secure boot and changed boot mode from UEFI to Legacy. This allowed me to install Ubuntu and the grub loader is also showing an option to either boot into Windows or Ubuntu, but whenever I try booting to Windows it says Cannot load.  This happens because the boot order is set to Legacy mode and Windows 8 will boot only with UEFI. I am unable to access my BIOS from where I can change the boot order. I press F1/F2 on booting but it doesn't load the BIOS, and directly goes to the grub loader screen.  How can I make my Windows 8 run along with Ubuntu?

I want to find this command, and then call it up in vi.  Thanks.  find . -name 'id.properties' How is an empty set truly "empty"? In a  question, an answerer says:  an empty bag is a bag with nothing inside it.  Makes sense, but I'm reading a textbook right now that says:  The empty set has only one subset (namely, itself).  Which seems odd to me. If a set is empty, why would it contain a subset? Regardless of whether or not the subset is also an empty set, the &quot;empty set&quot; still contains a subset, so how is it really &quot;empty&quot;? To go back to the empty bag analogy, it just sounds like my text book is saying:  an empty bag is a bag with nothing but an empty bag inside it.  Which doesn't make sense because then the bag isn't empty. I can't wrap my head around this concept. I made a map with annotations in QGIS 3.0.  This is how it looks like in the layout view:    If I print the map as PDF, one would expect to get the PDF to be WYSIWYG, right? However, it looks like this (it's about half the size):    Is there a way to influence the the scaling of the Annoations? I already tried to play with the Scale and Magnifier in the map view. I also tried to change the Scale in the map item.   The strange thing is, I believe it worked a few days ago. But today I installed QGIS 3.0 on a new PC and it showed the same behaviour...
