Is there anyone that knows what this font could be?
How do I find out what fonts are used in a document/picture?
I am able to successfully use wp.hooks.applyFilters() and wp.hooks.addFilter(), but I'm not able to render a React Component using wp.hooks.addAction(). However, the console.log() runs just fine within the callback for an action. This is my code:  import { createHooks } from '@wordpress/hooks';  let globalHooks = createHooks();  const Header = () =&gt; {     return (         &lt;h1&gt;Header Component&lt;/h1&gt;     ); }  const RevisedHeader = () =&gt; {     return (         &lt;h1&gt;Revised Header Component&lt;/h1&gt;     ) }  export default class App extends Component {      constructor( props ) {         super();          globalHooks.addFilter( 'replace_header', 'revisedHeaderCallback', this.revisedHeaderCallback );         globalHooks.addAction( 'after_replace_header', 'afterRevisedHeaderCallback', this.afterRevisedHeaderCallback );     };      revisedHeaderCallback( header ) {         return &lt;RevisedHeader /&gt;;     }      afterRevisedHeaderCallback() {         return &lt;RevisedHeader /&gt;;     }      render() {          return(             &lt;div className="App"&gt;                 { globalHooks.applyFilters( 'replace_header', &lt;Header /&gt; ) }                 { globalHooks.doAction( 'after_replace_header' ) }             &lt;/div&gt;         );     } } How to get my hover-menu back? Transformation issue with SVG to GeoJSON conversion I have a vector image in SVG format. (without georeferences)    I am trying to display it using OpenLayers to display properties of different polygons in it.  I tried converting it to GeoJSON but the resulting render appears to be stretched (ratios are not preserved).  Is there a transformation or a map projection that I am missing or recreating a GeoJSON from scratch the only relevant choice? Delay in approval leads to missing out on being awarded an "Explainer" badge RSA encryption with private key and decryption with a public key When using the RSA cryptosystem, does it still work if you instead encrypt with the private key and decrypt with the public key? What about in the case of using RSA for sender authentication? Question:     A man like you should not do this, _______?   Which question tag should I use in the blank space?   should he? should you?   Which would be grammatically correct? I think 1 is true. How can I heal undead creatures? Fifth edition seems to have removed any means of healing undead.  The positive/negative energy duality of 3rd edition seems to be gone. Negative energy spells now do necrotic damage; some undead are resistant or immune to necrotic damage, but it isn't listed as healing them. Classic negative energy spells like inflict wounds and harm don't list undead healing as a possible effect.  For zombies and skeletons it might not matter, but liches and vampires would never risk their necks if they didn't have some way to recover hit points. What is it? When $f(x+1)-f(x)=f'(x)$, what are the solutions for $f(x)$? The question is:     When $f(x+1)-f(x)=f'(x)$, what are the solutions for $f(x)$?   The most obvious solution is a linear function of the form $f(x)=ax+b$. Is this the only solution?  Edit  I should add that $f:\mathbb R\to\mathbb R$ to the question. 30" monitor has black border around desktop I have been using a 24" monitor with my macbook pro early 2011 connected via a mini display port to DVI adaptor.  I recently received an HP Z30i 30" monitor.  When I connect to it with an mini display port to display port adaptor, although it displays at the monitors native 2560x1600 resolution, the mac is scaling the desktop display down so as to leave a 1cm or so black border around the desktop.  The mac reports using a resolution of 2560x1600 and the display reports this also.   This makes the display blurry as single pixels become sub pixels.   The display looks like the same effect as having "under scan" turned on when using an HDMI cable at 1080p.  I thought that maybe there was a hardware or display problem, but when I boot off a previous system partition from a different hard-drive using the same OS (10.8.5) release, the monitor set up works perfectly.  This proves the OS release, display and the hardware, so I'm thinking that there must be a preferences problem with my current setup.  Perhaps the under scan setting is somehow being applied to this display when it's not using HDMI?  I've tried deleting /Library/Preferences/com.apple.windowserver.plist, ~/Library/Preferences/ByHost/com.apple.windowserver.HostNumber.plist and rebooting but no results.   The scaling is applied before the login screen and logging in as a different user has the same problem.  Any ideas?  It's driving me nuts, I've got this nice 30" screen and I can't use it! Android – Listen For Incoming SMS Messages Here $p$ and $q$ are co-prime integers. Is it necessarily an algebraic number? Why is $\frac{\operatorname dy'}{\operatorname dy}$ zero, since $y'$ depends on $y$? I know that $\frac{dy'(x)}{dy}=0$ (where $y'=\frac{dy(x)}{dx}$). The reason explained is that $y'$  does not depend explicitly on $y$. But intuitively, $y'$ depends on $y$, since if you vary $y$ you will modify $y'$. Why is my reasoning wrong (my reasoning sounds like it's related to functional calculus, instead of standard calculus)?  I tried to write  $\frac{dy'(x)}{dy}=\frac{d}{dy}\frac{dy}{dx}=\frac{d}{dx}\frac{dy}{dy}=\frac{d}{dx}1=0$, but this proof doesn't convince me.  I think that other way to see this is saying that if a function is of the form $f(y)$, it will not dependend on the variable $y'$.  But the same way you write $f(y)=y^2$, you could write $f(y)=\frac{d}{dx}y$, which clearly depends on $y'$. So I don't know if there are some types of operations which are restricted (for example, taking limits):  Note: The problem raises in the context of Classical Mechanics, where: $\frac{\partial L(\dot{x},t)}{\partial x}=0$. Let $R$ be an integral domain and let $S$ be a ring with $R \le S \le \text{Frac}(R)$ (fraction field).   Question: Is there a multiplicatively closed subset $U \subseteq R\setminus \{0\}$ such that $S=R[U^{-1}]$ ? I have an Optimus Elite, and it has a minimum brightness setting. In certain apps, I can reduce the brightness below the safe minimum, but when I leave the app, the brightness is increased to the system-wide minimum.  Using , I can permanently set the brightness below the safe amount, and it will stay even after going to other apps. Or using , I can accomplish almost the same thing even without needing root (it displays a translucent 'filter' over the whole screen, reducing brightness/contrast but not actually changing the backlighting power amount).  What I want to know is where the minimum screen brightness is stored. I have a rooted phone with CyanogenMod 9, so I have permissions to edit anything and could change a config or sqlite entry, but I don't know where this value is stored. What I would like to do is use the status bar brightness slider to be able to slide to the actual minimum of the screen, rather than the OS-controlled minimum. Having an app is useful, but having the functionality without the app seems to be within reach, if only I knew where the OS is getting it's safe minimum setting.  Where is this "safe minimum brightness" setting stored? If I can change it, I can remove my apps and use native controls. How do I remove duplicate "Open With" context menu items in Finder.app? For whatever reason, the "Open With" context menu in Finder is always listing every app four times (exactly).     I've read about (and tried) rebuilding the Launch Services database to restore the context menu to its initial state, but nothing seems to work. I've also used Onyx.app to clear user and system caches, but I'm still left with four repetitions of each app under the "Open With" service. I have restarted the system a few times just to be sure it was not some temporary corruption of the list.  I'm running OS X 10.6.6 on a 2011 17" MacBook Pro with a fresh install of OS X (i.e. I didn't use Migration Assistant.app or a Time Machine backup). I did, however, sync all my preferences and other files using MobileMe like I always do, so I imagine it's feasible that a preference file somewhere is causing problems? I didn't notice whether this was happening before or after my MobileMe sync.  How can I fix this so one app shows? Even though I got banned suspended, I'm able to mark a question as a favorite. Is this functionally correct? Windows 7 / 8 stop modal dialogue flash on parent focus Is there some setting in Windows where I can change the default behavior that causes the border and title of a modal dialogue box to flash like 6 or 7 times when I click on the parent window?  Simply focusing it would be plenty to let me know what I did was wrong.   I don't feel the need for all the sirens and bull horns and strobe lights to let me know I clicked in the wrong place. How do I unit test (using xUnit) a class that has internal private methods, fields or nested classes? Or a function that is made private by having  (static in C/C++) or is in a private () namespace?  It seems bad to change the access modifier for a method or function just to be able to run a test. How can I monitor my Samba traffic?

So if you have a foreach in your code followed by a new WP_Query then that is not what I am looking for (I am planning to put this onto my website's homepage).
