I wasn't sure, so I looked it up, and it would seem it's specific to single words.           1.) the derivation of a word.   Synonyms: word origin, word source, derivation, origin.      2.) a chronological account of the birth and development of a particular word or element of a word, often delineating its spread from one language to another and its evolving changes in form and meaning.   Synonyms: word history, word lore, historical development.      3.) the study of historical linguistic change, especially as manifested in individual words.   Obviously the following sentence would be easily understood, but is it technically correct?  Or is there a better way to ask the following question?  “What is the etymology of the Baseball term 'meat hand'?”  As in a first-use, or how the phrase came to be, or what made it popular – etc.  What I think of as “etymology”, but perhaps that word is more technical, and specific to the linguistic breakdown and origins of individual words.
I have always heard the term used in referring to a single word. When browsing questions on this site, I've seen it used applied to entire phrases, and have suppressed the compulsion to edit them and replace the term with origin.
What are some good ways to showcase someone's portfolio work online? How many authors should attend a conference? I wrote a paper with  3 other students regarding my final year project in mechanical engineering. It was recently selected for a conference in NIT Delhi. Minimum one author is required to present and the price is pretty steep for the participation certificate.Should all of us attend the conference or just one of us? Does the certificate hold any value? Have a seat, guys   I think "have a seat" is a fixed phrase that does not change whether you address someone or a group of people.  Is that correct?  If you have more to add to the post, please do so as I would love to know more. What options do I have to replace a failed service panel? What are my options to replace an old service panel?   We had a terminal get burned up in our old 1960s GE (TRX2012S if it matters, it's a split-bus/rule-of-six panel).   The tech who looked at it said the part is no longer available, but that if I could find another old service panel just like it, he could swap in the part. Otherwise, it's going to be $2,000+ to replace it with a modern service panel, which also requires getting up to modern code, which involves a lot of other stuff.   EBay and Google isn't showing any direct replacements (or the flush-mount TRX2012F).    What other options would there be to replace the panel internals?  Are the screw mounting holes compatible with modern GE panel internals? Is the main breaker separable and could that be changed alone?    Enclosure dimensions are about 20.5" x 12". Front panel dimensions are about 22.25" x 14".  UPDATE:    I'm looking at information on replacing the breaker box myself. As the homeowner I wouldn't be required to update anything else to get up to code. Does this sound like a good idea? I've done minor electrical DYI work but nothing this involved.  PICTURES:            More pictures: How to effectively close a page? Before asking my question, I'll use an example to clarify the idea.  Say that a company used to sell horses and then they turn into a sheeps business. While some of the old pages can be mapped to the new pages using a 301 redirect, because they're really related in the content and the company don't want to lose users and link juice, there are a lot of pages strictly related to horses that they want to shutdown.  What's the best practice? Is there a way to say to users and Search Engines the content you were looking for won't be available any more?  Basically a 301 redirect of the closed pages to new ones seems not so good, because you'll show a content totally unrelated to the searched one.  P.S: I'm aware that probably the best fallback is to simply map those pages to the homepage but I hope in a smarter solution. I was doing some practice problems that my professor had sent us and I have not been able to figure out one of them. The given equation is:  $-y^2dx +x^2dy = 0$  He then asks us to verify that:  $ u(x, y) = \frac{1}{(x-y)^2}$  is an integrating factor.   I multiplied through to get:  $\frac{-y^2}{(x-y)^2}dx + \frac{x^2}{(x-y)^2}dy = 0$   However, the partial derivatives of these do not equal each other so I am a bit confused... Why can't I chown a VirtualBox shared folder? Does anyone know if there is an API to get the current monitor state (on or off) in Windows (XP/Vista/2000/2003)?  All of my searches seem to indicate there is no real way of doing this.    tries to use  which according to Microsoft's docs does not work for display devices.   In Vista I can listen to  but I do not seem to get events when the monitor is turned off manually.   In XP I can hook into WM_SYSCOMMAND SC_MONITORPOWER, looking for status 2. This only works for situations where the system triggers the power off.   The WMI Win32_DesktopMonitor class does not seem to help out as well.   Edit: Here is  on comp.os.ms-windows.programmer.win32 indicating there is no reliable way of doing this.   Anyone else have any other ideas? How to combine bold and "code sample" in Markdown? Viber notification is not in the right position What's the 'correct' way of registering/installing an Assembly to the GAC? There seems to be lots of different ways to register assemblies with the GAC, as in, they 'work'.  However, what's the "proper" way of doing it?  In response to Lou Franco (and gacutil):  I'm using Gacutil for development, but it seems to me to be not the proper way to install it, since gacutil isn't included in the basic .NET utilities past .NET 1.1 - it's only a developer tool.  Additional: Gacutil (as seen in responses below) is not redistributable, and therefore should not be used in any app that you intend to give to people who are not developers.  AKA, customers.  See .  In response to using WIX:  WIX might be great and all, but how does it work under the hood?  What details makes the way WIX installs the assembly the right way to install it?  How does it look it up?  Is it a system/.NET call?  Is there some call in a dll buried somewhere in System32 that needs to be made?    (Edit: it looks like WIX uses MSI under the hood.  See my comments in the accepted answer.)  Final edit: It looks like the correct way to install an assembly to the GAC is using windows installer, and nothing else.  I'm going to give Wix a try.  Thanks all! where do I use Database. Methods? I m trying to understand where we use following Database.Methods. I know if we want to insert a record to an object we use DML Statement. What i want to know is why/where we use Database. methods. It might be silly question. Database.saveResults Database.insert Database.query Database.Query Database.error   really appreciate the inputs. Thanks a ton in advance. Travelling through the Schengen area with a Refugee Travel Document issued by the USA I just want to double check to make sure I won't run into any issues at the border of entry.

I'm not allowed to execute the ls command and parse the results from within my program. Bearing in mind I am a layman - with no background in physics - please could someone explain what the "big deal" is with quantum entanglement?  I used to think I understood it - that 2 particles, say a light-year apart spatially, could affect each other physically, instantly.  Here I would understand the "big deal".  On further reading I've come to understand (maybe incorrectly) that the spatially separated particles may not affect each other, but in knowing one's properties you can infer the other's.  If that it the case, I don't see what the big deal is... 2 things have some properties set in correlation to each other at the point of entanglement, they are separated, measured, and found to have these properties...?  What am I missing? Is it that the particles properties are in an "un-set" state, and only when measured do they get set?  (i.e. the wave-function collapses).  If this is true - why do we think this instead of the more intuitive thought that the properties were set at an earlier time?

Upon its expiration, I would like to get my 90/180 days validity as a tourist to stay, or return here as soon as possible.  I understand that the tourist short-stay scheme is based on the 90/180 days "counter". But what happens if my previous stay was not tourism but residence (as searching year). Wouldn't that mean that I can quickly exit and re-enter the Schengen area to activate my tourist stay?   Also, is there a way to change this purpose of stay without exiting the Schengen area? How do I show that all continuous periodic functions are bounded and uniform continuous?
