How to define constant before plugin I have the plugin which have constant defined, i will call this plugin PLUGIN A:  if ( ! defined('BLA')){     define('BLA', 'http://google.com);  }   I want to make another plugin PLUGIN B which will define constant BLA before PLUGIN A. Is that possible? I guess Wordpress needs to read PLUGIN B before PLUGIN A, but in which order Wordpress is reading plugins?
In what order does WordPress load plugin files? In what order are plugins loaded in WordPress?   And within a particular plugin's folder, what order is followed for loading?
Is it possible to use the enumerate/itemize environment within the proof/remark environment in a nice way? I'm wondering what the preferred method is for dealing with AJAX calls. Should one use the same plugin php file to process the POST or a separate one? Which is cleaner or safer? How do I add Headers in List of Tables page? I have a notebook with no Scroll Lock key (or any shortcut using the 'Fn' key).  Somehow Excel 2010 got the Scroll Lock on. I see it left down in the status bar and now I can't navigate through cells using the arrow keys, which is pretty annoying. It wasn't turned on some hours ago, so I think I must have hit some Scroll Lock toggle shortcut in Excel 2010 by mistake.  Anyone knows what hot to turn off Scroll Lock in Excel (shortcut or menu option)? Sqrt disappeared when exporting plot to PDF in version 10 Why is my Wi-Fi connection speed much slower than a wired connection? When I plug my laptop via LAN cable and check speed on speedtest.net I have over 32 Mb/sec. When I unplug the cable and connect to the same router I have less than 15 Mb/sec. I tried to change channels already but this didn't help. I'm sitting just near the router.   What can it be? The router is a Dlink 400. $a,b,c$ are real numbers $>0$. If $a+b+c=1$, show that $(a+\frac{1}{a})^2+(b+\frac{1}{b})^2+(c+\frac{1}{c})^2\ge\frac{100}{3}$ Search field with or without a button? I can see two broad patterns as far as the design of the search field is concerned. One like we see on Google has a button that the user can hit to initiate Search. (They could also hit enter to do so)  The other pattern much like what is on this site (stackexchange) do not have a button. So the only way the user can initiate search is by hitting enter.   Has anyone done any research or analysis of this pattern ? What I have noticed is that search fields without the explicit search button (that normally is a magnifying glass) have "Search" as placeholder text, left aligned, whereas when there is no button the placeholder is usually a "Magnifying glass icon" with "Search" all left aligned. "Friendly" terminal color names in shell scripts? I'm aware of libraries in languages such as Ruby and Javascript to make colorizing your terminal scripts easier by using color names like "red".  But is there something like this for shell scripts in Bash, or Ksh, or whatever? Converting points to raster in ArcGIS?

I am trying to calculate the sum of this infinite series after having read the series chapter of my textbook: $$\sum_{n=1}^{\infty}\frac{1}{4n^2-1}$$  my steps:   $$\sum_{n=1}^{\infty}\frac{1}{4n^2-1}=\sum_{n=1}^{\infty}\frac{2}{4n^2-1}-\sum_{n=1}^{\infty}\frac{1}{4n^2-1}=..help..=sum$$  I am lacking some important properties, I feel I am coming to the right step and cannot spit that out.. How can I show only unnamed faces in Mac photos I was trying to show photos with unnamed faces so that I can annotate them. There is  but it requires you to mark all the pictures with no faces at all. Any suggestions? How do I put /home in a different partition? Yeah, so I have 2 hard drives, on with 2 partitions(backups and windows), and I have another that also has 2 partitions with only one used. I have Ubuntu on hard drive 2:partition one, but I have come to a point when the /home folder can't hold any more files, but the partition is only about 15% filled up. So I did some researching and figured out that you can put it on a separate partition, but most of the guides were vague on what I needed to do. Could someone give me step-by-step instructions on what I need to do, or even tell me a, easier or different way to fix this /home folder capacity problem? How can I identify an anonymous inner class in a NotSerializableException Explanation behind Second Derivative of a Parametric Equation Formula I am looking to find out how the second derivative formula works.  I can blindly apply it but I don't have a grasp of what is going on or why. The first derivitive has the formula $\frac{dy}{dx} = \frac{\frac{dy}{dt}}{\frac{dx}{dt}}$. I told this was because if you divide them you cancel out the dts and get dy/dx. The second derivative has the formula $\frac{d^2y}{dx^2} = \frac{d}{dx} \left(\frac{dy}{dx}\right) = \frac{ \frac{d}{dt}\left(\frac{dy}{dx}\right) }{\frac{dx}{dt}}$. Is this something that can be explained with only a knowledge of calculus or is this something I would have to take on faith until I learn more. Any help would be greatly appreciated.
