Why use definition lists (DL,DD,DT) tags for HTML forms instead of tables?
Stack Overflow in ES, PT, RU, JP have mixed-language descriptions I hope I'm right in thinking this is the site where you post general computer-related problems...  A problem I have when playing games (since you won't be pressing multiple keys simultaneously anytime else), is that when I press up/left and then another key, it fails to 'register' as if that last key is never pressed. This doesn't happen when I'm pressing any other two arrow keys, e.g. down/left or up/right. The weird thing is that when I'm playing with WASD instead of the arrow keys, i still have this problem! Meaning W+A+another button doesn't work.  If anyone knows what I should, I'd appreciate the help. (My reflexes are fast and I can always circumvent this problem, but it's quite annoying and shouldn't exist to begin with!) Take for example  both at SO and SU. Now that there's , (new) users asking a LaTeX question should at least be informed that there is a new Stack Exchange site dedicated to TeX and thus increases their chance of an answer. This should happen before the question is actually posted and ideally offer the option to post the question directly there instead (without the need to copy-paste).  LaTeX is just an example, there's also , ,  etc., and it is obvious that this can only be decided on a case-by-case basis which is why I certainly do not suggest migrating questions automatically when these tags are used. But informing users of that possibility would probably help the SE network in general. What is the meaning of this senctence:Excellent answer. Delusions of grandeur. Folks have been institutionalised for less Can an atheist at least agree that existence is a mystery that is bigger than all of us?                                                       You’ve got it backwards. It’s religious people who try to fill the mysteries of the universe with beliefs based on nothing emprical. Where atheists say “I don’t know” religious people say “It’s God.” Atheists are comfortable with not knowing everything. They know humans are infinitesimal specks in the universe. Religious people think the entire universe was created for and about them. Talk about grandiosity. Comment:Delusions of grandeur. Folks have been institutionalised for less lol Want to fill line with repeating string Similar to the \dotfill command, but with your own text, rather than dots.  If the string was: kitty!  The entire line would look like the following: kitty!kitty!kitty!kitty!kitty!kitty!kitty!kitty!kitty!  Is there any way to do this? How to create an OD road distance matrix in QGIS? I'm looking for the steps required to produce an origin-destination (OD) cost matrix.  What I'm looking for is a matrix of road distances. The distance matrix tool only produces euclidian distances. The QGIS Roadgraph plugin produces the shortest road distance from one origin to N destinations. What I need is a file containing distances from all origins to the N closest destinations. I have a lot of origins so repeating the analyses with Roadgraph is not an option. Thanks again.  I'm looking for a step-by-step description, starting from scratch (ie, with my 3 shapefiles: origins, destinations, road network). What are the consequences of "copying" a data set for OLS? Is it possible to experimentally show that observable universe is much larger than ~93B ly? Bypass GeneratedValue in Hibernate (merge data not in db?) raw data stationary but still can see trend and seaonality is stl Is there a characterization of groups with the property $\forall N\unlhd G,\:\exists H\leq G\text{ s.t. }H\cong G/N$? A common mistake for beginning group theory students is the belief that a quotient of a group $G$ is necessarily isomorphic to a subgroup of $G$.  Is there a characterization of the groups in which this property holds?  If this question is too broad, I might ask if such a characterization exists for $p$-groups.    History: I originally posed the opposite question, regarding groups for which $\exists N\unlhd G\,:\, \not\exists H \unlhd G\, \text{  s.t. } H \cong G/N$, and crossposted this to .  I received an answer there to the (now omitted) peripheral question about probability, which shows that most finite groups probably have this property.  After this, I changed the question to its current state, as this smaller collection of groups is more likely to be characterizable. Every principal ideal domain satisfies ACCP. Foreword  This question was inspired by initial mistakes in . I wanted to explore the strange circle with $A&gt;\pi r^2$ and got lost into geometrical jungle.  A  is usually described by it's height $h$, radius of the base $a$ and radius of the sphere $r$. Besides we have a relation $a^2+(r-h)^2=r^2$ so the cap actually only has two degrees of freedom.  When considering a case of circle on a sphere (like the Earth), it's the surface of a spherical cap, but we can't see the height or other classic parameters of this spherical cap. Instead we encounter parameters like area $A$, perimeter $C$ and diameter $d$. I will try to write formulae for these: $$A=2\pi rh$$ $$C=2\pi a$$ $$d=2r\theta$$  Where $\theta$ is introduced with $\sin\theta=\frac{a}{r}$ or $\cos\theta=(1-\frac{h}{r})$.  As the cap only has two degrees of freedom, it should be a good problem with unique solution if only two values are known.  A-C Problem  The simple example: $A$ and $C$ are given. I show this only as example before the other tasks.  We can easily find $a=\frac{C}{2\pi}$ and then solve:  $$A=2\pi rh = 2\pi r (r-\sqrt{r^2-a^2})$$  to obtain  $$r=\frac{A}{2\sqrt{\pi(A-\pi a^2)}}$$  Parameters $a$ and $r$ are now known and it is straightforward to find $h$, $d$, $\theta$ and anything else.  C-d Problem  $C$ and $d$ are given.  First step once again is easy: $a=\frac{C}{2\pi}$. The knowing of $a$ suggests that we might prefer the $\theta$ definition with the sine. We obtain: $$d=2r\theta=2r\arcsin\frac{a}{r}$$  That's where I got stuck. Is there an easy way to solve this? Is there a hard way to solve this?  I tried solving numerically with Wolfram Mathematica and it went into complex numbers. When solving the geometrically equivalent $\sin\frac{d}{2r}=\frac{a}{r}$ I got some roots, but the search seemed very unstable and not finding the root closest to initial value. Besides it was finding a lot of different roots while I am pretty sure that there should only be one $r$ for each pair of $d$ and $a$. What would be the right formulation to solve this problem numerically?  A-d problem  $A$ and $d$ are given. This seems the hardest one. We obtain a system of equations:  $$A=2\pi r h$$ $$d=2r\arccos\left(1-\frac{h}{r}\right)$$  (The first equation suggested solving the problem in $h$ and $r$).  Is this system solvable analytically? Or numerically? My experiments with Wolfram Mathematica never converged.   Of course, I could express $h$ or $r$ from the first equation and leave only the second in one of these forms: $$d = 2r\arccos\left(1-\frac{A}{2\pi r^2}\right)$$ $$d = \frac{A}{\pi h}\arccos\left(1-\frac{2\pi h^2}{A}\right)$$  But I have no idea how to solve these either. Does using an extender actually change the aperture of the lens? I just bought a Canon 2X extender and I always believed that it would only result in 2 stops' loss of light and not change the aperture.    However, when I tested this extender on a Canon 135mm f/2 lens, the maximum aperture I could set went down to F/4.  So it kind of confused me, because if I step down the aperture to f/5.6, is it actually setting the aperture to f/5.6 or f/2.8 (i.e., 1 stop below f/2)? Bitlocker won't initialize on a 4TB drive with 4K sectors How can I disable the Document Library drag and drop function? Before I start - I'm new to this SharePoint development lark and am slowly familiarising myself with it.  We're using SharePoint online and I have amended the SharePoint out-of-the-box document library to include some extra fields that are required when the user adds a new document.  If the user creates or uploads a new document then they are prompted to enter the required information. However if they use the drag and drop functionality the entry of the necessary fields is bypassed.  During my search I came across  which asks how to enforce metadata entry (which would be another good option for me). It also mentions disabling the drag and drop functionality by editing dragdrop.js and removing content from various methods.  I've had a look at the site collection I'm working on (to which I have full control) and I can't seem to find dragdrop.js (or the layouts folder for that matter).   Is this something that's held at site collection level or is it held at a higher level? I don't have admin rights above my site collection, do I need them? Do I need to use Visual Studio to make the necessary changes? (Currently I'm doing things through the web and having a bit of a play with Napa I don't have Visual Studio installed)  When I get there is it obvious what methods need to be removed? How can I tell SharePoint to use the new version of dragdrop.js? Is it just a case of saving a copy of the existing one to a different name and then editing the existing file?      I suppose the best place for me to have asked this question would probably have been on the existing post, but I am unable to post a comment on there, sorry... Is it appropriate to remove excessive commenting from code? I am referring to this question on SO , where there is a massive amount of commenting within the code (the question has since been edited to correct this).  Is it allowed to remove these for the sake for readability (the comments just specify some lesson details, method comments etc)? preventDefault when clicking bounty "cancel" link When you click "start a bounty" then "cancel," href="#" exiles you to the top of the page and you lose your spot near the end of the question's comments. Clicking anywhere else on the page simply closes the bounty popup; clicking "cancel" ought to do the same.  In case that wasn't clear:    Dramatization aside, it's a nuisance. Can the click event on that anchor be preventDefaulted? Compiz Problems (Plugin Missing, Performance Issues, Development) How do I get the Glare node to output transparent instead of Black background This is what I have so far:  The rendered image has a transparent background, but the glare filter creates an output with a black background, so after merging the two togheter, the background turns black but I need it to be transparent, what can I do?
