What is a domestic tap called commonly in the US ?  -a spigot?   a device that controls the flow of liquid from a large container (MW)   Dictionary meaning aside, I had this understanding that a domestic tap is known as a faucet.
I always thought water sources were called taps in kitchens, bathrooms etc, but a Google search only returned outdoor taps.  So my question is, what are indoor taps really called? Like this one:
Can moving tables to another MySQL database help performance? I want to know if I using different databases can help performance.  I have one big table support_chat with more than 5 million rows. I need to scan this all the time (3s with ajax) to check new messages on support.  If I move this table to another database in the same computer, can it help anything? (let users, sells, comments table faster)  For example:  db1  users table sells table comments table support_chat table // move this table to db2   db2  support_chat table   They want to keep old things due legal reasons, to have a user support history. How to apply for a Schengen visa when the travel dates are uncertain My husband has a Chinese passport and I am a U.S. citizen; I don't need a visa to travel to Schengen countries. I am helping him to apply for a visa.  Our plans are to go to Paris, Italy and Spain, but we haven't nailed down definite dates; the approximate dates are August 18 to September 11. We made an appointment with Spain consulate to apply for the visa. We need to show air flight reservations, I could book it online without any problems.    Since we don't have definite dates, what dates should he put down on the application?  I know that, once they approve you, they give you 90 days, so does it matter what dates I put down on the visa application?   Our appointment at the Spanish Consulate is in a few days. Application is "Ready to Sale" but not reflected on iTunes Store arXiv is smart enough to detect whether your PDF is generated by LaTeX. If it is, arXiv asks for the sources of the PDF instead of the PDF file itself. This is really annoying and inconvenient.  I ask a way to fool the arXiv and avoid PDFs being detected as generated by LaTeX (even if they were indeed).  I have tried this: : "create a pdf from word and then simply insert pages from your article, and delete the word's page".  And it did not work. How would one write object-oriented code in C? What are some ways to write object-oriented code in C? Especially with regard to polymorphism.    See also this Stack Overflow question . I'm using Fedora and wonder if there is some way I can exclude kernel updates when I run yum update, until I specifically want to update the kernel.    The reason why I am concerned about this is because sometimes it requires a lot of extra research finding patches for some programs and extra time spent recompiling them to work on the new kernel.  I am thinking VMWare specifically as one example.   I wonder if there is some way for yum update to NOT update the kernel and only notify me that a new one is available when it goes through its routine so that I can decide to put it off until a more convenient time.  Or is this thinking likely to cause other issues? Let $x$ and $y$ be positive integers such that $xy \mid  x^2+y^2+1$. Show that $$ \frac{x^2+y^2+1}{xy}= 3 \;.$$ I have been solving this for a week and I do not know how to prove the statement. I saw this in a book and I am greatly challenged. Can anyone give me a hint on how to attack the problem? thanks Will some parents be offended when being asked, "Is it male or female?" If I ask the parent about a baby's gender, will it be impolite or not appropriate to say, "Is it male or female?"  Is there any subtle difference, in terms of politeness, among   "Is it a boy or girl?" "Is it he or she?" "is it male or female?" How can I remove the Trash icon from the Unity launcher? I would like to not show the trash icon at the bottom of the Unity launcher.  Is this possible without having to recompile anything? :P Detecting outliers using standard deviations Following my question , I am wondering if there are strong views for or against the use of standard deviation to detect outliers (e.g. any datapoint that is more than 2 standard deviation is an outlier).  I know this is dependent on the context of the study, for instance a data point, 48kg, will certainly be an outlier in a study of babies' weight but not in a study of adults' weight.  Outliers are the result of a number of factors such as data entry mistakes. In my case, these processes are robust.   I guess the question I am asking is: Is using standard deviation a sound method for detecting outliers? Yes, I know the topic has been discussed before. I know that Meta already has threads that complain about how flagging doesn't work. I wanted to give a practical example.  Today, a  came in to the  chat and asked the :  Hey guys, as soon as I embed javascript, all my html elements are gone. Even if the script is empty!? ...Can anyone help out? The example is really minimalistic &lt;script type='text/javascript' src=&quot;http://ajax.googleapis.com/ajax/libs/jquery/2.0.3/jquery.min.js&quot;/&gt; &lt;script type='text/javascript' src=&quot;script.js&quot;/&gt; These lines make everything vanish. script.js is empty! I use google chrome and the file is on localhost  Some context:  The JS room encourages people to come and ask questions that are too small/badly put for main. The room encourages people to just ask questions rather than ask to ask. In fact we even have a bot that prompts users to just ask if they have a question whenever they join. The above user has a good Q to A ratio having 1K rep in the main site and over 80 answers. The user has no negative context in the chat. No previous offenses or anything like that.  That message got 7 flags  Had a mod (ThiefMaster) not been present and invalidated those flags in time that user would have probably been suspended from the chat. This is bad, it sends the wrong message and it is very rude. Now, some other rooms don't allow people to just come and ask questions right away so maybe users from other rooms validated the flag. Maybe users thought he was being rude? I don't know. I do know that we don't want this sort of negative atmosphere in the JS room (and I'm sure other useful rooms such as PHP don't want it either), we have enough on our hands trying to maintain a community while helping people joining and handing with vamps/trolls. Possible solutions:  Drop spam/offensive flags altogether. Make spam/offensive flags room specific for big enough (tm) rooms. Give room owners just the ability to invalidate spam/offensive flags. Increase the highlighted button bezel thickness (GNOME) Integration by partial fractions; how and why does it work? Dual edge detector I am designing a hobby project that will run on a battery so I am trying to reduce power consumption. The SoC I am using has the ability to go into a deep sleep mode where it consumes very little power, and then can be interrupted by a falling edge on a pin.  I want to generate a high-low-high pulse when the state of a reed switch changes in either direction. I have been reading a lot and it seems that a one-shot monostable circuit can be built from a couple of transistors and an RC circuit to generate an output pulse when an edge is detected. I understand how that works. However, I can't figure out the best way to also pulse on the opposite edge.  One thought, was to just combine two one-shots that are configured to trigger on rising and falling edges respectively, and use the transistors at the output to pull the common pull-up low (kind of like a NOR gate).  Since I am a hobbyist, I am mostly using passive components. What is the "real" way of doing this in a low-power configuration using logic devices?  Edit: I figure I should mention something about the timing requirements. Normally the reed switch will be either open or closed for many seconds at minimum before changing states.  Edit: Here is an example of the circuit I was using for detecting only the falling edge:    And here is the ~20ms pulse it was producing for ~200ms button press simulating the reed switch (Channel 1 is Vbe for T1 and Channel 2 is measured at RST): How do I report a bug? What do the different colours in Ubuntu's ls command mean? For example, when I type the ls command in one of my folders, I get one of the files in light green, the other (which is a folder) in blue with green highlighting.   What do those colours mean, and there is any manual about all the colours? What happens to Zhang ziyi (Jen) in  when she jumps off the cliff .. she dies? becomes immortal?

In some cases, this can differ from $$.   Above explanation , explained $BASHPID variable.  Question: which cases? What is the bit size of long on 64-bit Windows? Not to long ago, someone told me that long are not 64 bits on 64 bit machines and I should always use int. This did not make sense to me. I have seen docs (such as the one on Apple's official site) say that long are indeed 64 bits when compiling for a 64-bit CPU. I looked up what it was on 64-bit Windows and found         Windows: long and int remain 32-bit in length, and special new data types   are defined for 64-bit integers.      (from )  What should I use? Should I define something like uw, sw ((un)signed width) as a long if not on Windows, and otherwise do a check on the target CPU bitsize? Origins of the nose-bleed in anime/manga In a similar spirit to my , I wonder who was the first artist to feature a nose-bleed when thinking, shall we say, "provocative thoughts"?  Did it become popularized in anime/manga because of the popularity of the artist's work or because it is a common belief in japanese folklore?
