I hope this is not a repeat question. I tried searching but couldn't come up with the right search words for this question.  I see the following in the sidebar of my flagging history tab:    I notice that I have raised 28 helpful flags from my user page, but I see "27 deemed helpful" and "1 deemed helpful". What is the difference between the top half and the bottom half of the entries in the flagging history sidebar? How should I interpret the results displayed in the sidebar?
The  (click on your number of helpful flags in your profile) is cool, however some posts have a gray background, some don't. What does it mean?  example:
Android: fragments overlapping issue I've been reading up on STL containers in my book on C++, specifically the section on the STL and its containers. Now I do understand each and every one of them have their own specific properties, and I'm close to memorizing all of them... But what I do not yet grasp is in which scenario each of them is used.  What is the explanation? Example code is much prefered. What is Peter Quill's status after Guardians of the Galaxy Vol. 2? Who are the clients of my shared iTunes library? Is it possible to see who is currently connected and listening to a shared iTunes library? Is it possible to see which songs they listen to and how many/often?  It's not really important; I'm just curious about it. Would be nice to know which colleagues love my music… MacOS partition showing as "FFFFFFFF-FFFF-FFFF-FFFF-FFFFFFFF" This is a  about setting up .     I have an office with many computers that share a single external ip (I'm unsure if the address is static or dynamic). Each computer connects to our mail server via IMAP using outlook. Email is sent and received by those computers, and some users send and receive email on their mobile phones as well.  I am using  to generate an SPF record and I'm unsure about some of the fields in the wizard, specifically:   Enter any other domains who may send or relay mail for this domain Enter any IP addresses in CIDR format for netblocks that originate or relay mail for this domain Enter any other hosts which can send or relay mail for this domain How stringent should SPF-aware MTA's treat this?   the first few questions i'm fairly certain about... hope i have given enough info. Getting raw SQL query string from PDO prepared statements Is there a way to get the raw SQL string executed when calling PDOStatement::execute() on a prepared statement? For debugging purposes this would be extremely useful. By accident, I recently removed some videos from my phone. I tried to restoring them with Recuva and TuneUp Utilities and the results were "undf" files.  I tried to open with VLC, Media Player Classic and other video players to no avail. Where/how do I find out the codec for these files?   I would really love to be able to watch these videos again. 2018 Macbook Pro & Dual Monitors I'm trying to hook up dual monitors (Samsung CF390) to my MacBook Pro, but when I do, I only have the desktop image projecting on both screens. When I go into Settings > Display, the "Arrangement" option isn't available.  I have both monitors' HDMI cables running through 1 USB-C to HDMI adapter. (The adapter has two ports.)  Is the solution to this problem having two adapters? My thinking is even though the adapter has 2 ports, the MacBook hardware or software can't Fully make use of both displays.   What can I change to get three total displays working on macOS High Sierra (10.13.x)? Qt: Best practice for a single instance app protection 18.04.01 Not available for server For $a, b \geq 0$, $0 < x < 1$, show $(a+b)^x \leq a^x + b^x$ Let $a, b$ be positive real numbers. Let $0 &lt; x &lt; 1$. Show that  $(a+b)^x &lt; a^x + b^x$.  The function $f(x) = (a+b)^x -a^x - b^x$ has $f(0) = -1$, $f(1) = 0$ and it seems to be an increasing function. But I am unable to show that it is increasing function. Finding files by only knowing extension? I'm somewhat disorganized in my file saving habits, so I wind up using the Search function in Windows Explorer more often than one should. I was wondering, is it possible to have Windows find all files of a certain extension ( like, say for example all .rar files) if it is, how? In which scenario do I use a particular STL container? I've been reading up on STL containers in my book on C++, specifically the section on the STL and its containers. Now I do understand each and every one of them have their own specific properties, and I'm close to memorizing all of them... But what I do not yet grasp is in which scenario each of them is used.
