In chat, I can read events by sending a POST request to this URL:  http://chat.meta.stackexchange.com/chats/roomID/events   However, there seems to be a Same Origin Policy, preventing CORS. Could it be changed to allow it from everywhere?  Access-Control-Allow-Origin: *   This would make many things easier for us.
I was working on a userscript today, which had a goal of displaying chat pings immediately at the main site. This would allow me to respond more quicker-like to chat pings.  However, I was met by this fearsome warrior:     Can we please set some decent header things? I want to be able to do this really bad.
What do viruses do? There are those big green spiked things that my friends call viruses. I don't know what they do and I want to know. Do the viruses do something to the device you are playing on? Are they good or bad? Column and row padding in tables Show hidden files on Mac OS X Mojave using Terminal To see my /etc folder I've tried this command in Terminal:  sudo chflags nohidden /etc   followed by:  sudo defaults write com.apple.Finder AppleShowAllFiles true; killall Finder   also tried:  sudo defaults write com.apple.Finder AppleShowAllFiles YES; killall Finder   Neither of them seemed to work. Where did object dimensions go in 2.8? Is there a single word that describes both Witches and Wizards? In the Harry Potter world, there's the term "muggle" for people with no magical abilities, "muggle-born" for those with magical abilities who's parents are muggles and "squib" for those with no magical abilities who's parents are magical.  But is there any collective term for all magical people (as opposed to wizards for males and witches for females)?  I don't recall seeing any word that refers to all men and women and children with magical abilities, and it's the only group left without noun or collective noun to describe them. How do I get the number of days between two dates in JavaScript? For example, given two dates in input boxes:  &lt;input id="first" value="1/1/2000"/&gt; &lt;input id="second" value="1/1/2001"/&gt;  &lt;script&gt;   alert(datediff("day", first, second)); // what goes here? &lt;/script&gt; Which is the right way to do something like 'description' list but with customizable and fixed-width labels? I.e. something like this:  Label:         Text text text text text text                text text text text. Longer label:  Text text text text text text                Text text text text.   The way I see it to use two-column table (first columt for labels and second column for descriptions), but this solution seems ugly. Is there any other way? reveals x2 code snippets. The first result is to  which has a lot of documentation and explanation, along with some useful discussion underneath.   However, , whilst not containing so much documentation, includes sample code for passing commands such as start, stop and restart. It also creates a PID file which can be handy for checking if the daemon is already running etc.  These samples both explain how to create the daemon. Are there any additional things that need to be considered? Is one sample better than the other, and why? Are Playstation 4 games locked to a certain region? This question has been asked before, but it was for PS3 and Xbox 360 and was asked August 2010. This time around my question goes specifically to PS4, since I'm moving from Mexico to Europe and I was wondering if the European games will run in my console or if I'll have to buy a new one. I never thought of this before (which is why I never paid attention if it was mentioned in reports or specs of the console) and the research I did wasn't too helpful. Attending graduate school at my undergraduate university I've been told by numerous people that (1) my undergraduate university will be disinclined to bring me on as a graduate student, and that (2) it's a bad idea to attend grad school where you completed your undergraduate degree, anyway.  Is that true? If so, why? How can I add a new user as sudoer using the command line? Quick way to remove solidify thickness I have made the mesh and added solidify modifier and applied. But later i thought to increase the thickness. So now i want to remove thickness so that i can added the solidify modifier again. I want to know is there any quick remove thicknes. When i select the edge then ctrl+ the selection goes downward not to single face. So i want to know a quick way to decrease thickness. Any suggestion or help. How to create a bootable USB with multiple ISO images in it Bounding lines around tax nodes I am trying to draw lines around a number of nodes. I very much like the definition of \convexpath definition given , but it is not working well on my setup (MacTex 2014 with all available updates).   I tried to compile , but what I get is the following, which is clearly not what I should be getting. Any ideas would be much appreciated. I have quite a bad habit of copy-and-pasting my packages from one LaTeX document to another. Is there any way we can detect unused packages (i.e. \usepackage commands) so that they can be removed from the LaTeX document? What's the difference between STDIN and arguments passed to command? How are Star Wars blasters properly reloaded/charged/etc.? I've been looking into the inner workings of blaster weapons primarily using Wookieepedia. While most of it I understand, I still can't figure out how many rounds a gun would fire before needing the ammunition component replaced/reloaded. Is there any solid answer?  I'm someone who likes to design and draw his own weapons and such, but likes to keep to how the technology of an era is in mind. While Star Wars weapons don't really have magazines (and you don't really see them reloading during battle), other people's work still has magazines and treat ammunition consumption as though it's pretty much the same as our modern era.  I guess that I just find it hard to believe, with the technology of the Star Wars Universe, that characters would need to carry lots of ammunition (hence why clones/storm troopers/battle droids don't visually seem to carry very much).  Example: DC-15A     "The weapon's tibanna gas cartridge carried enough gas for up to 500 shots, depending on the power settings of the weapon, while the charge pack lasted about 50 shots"   Source:   I've read in several places that this can be seen in two different ways.  1. Which ever ran out first, had to be replaced before the weapon could fire again. 2. The weapon contained two different sources of ammunition (so I guess you could switch between the two) why is my screen black after rdp connection? After connecting from my home via remote desktop, both my screens are black when I arrive at work. The only thing I can see is a mouse pointer on one of the screens. I then seem to have only two choices: rebooting or working from a remote desktop connection, which works fine.  It did happen every time I tried last week.  However, I did the same from my laptop in a meeting room today, and I didn't have any problem. An equivalent condition with $\{0\}$ being the only nilpotent ideal This is trigonometry from double angles and compound angles. Thus far I've simplified it up to this point. $$2 \sin^2θ – 3\sinθ +1 = 0$$  I'm trying to factorize this to solve for General Solution. I tried taking out a common but that +1 is giving me a problem. I used the quadratic equation to get 1 and 0.5 as an answer, but i don't know how to write it in terms of 2sin(squared)θ and -3sinθ.  Any help will be appreciated.
