I haven't been able to infer whether latin characters are different from English alphabet or English alphabet are a subset of latin characters, as I came across several versions of latin.  Trying to find an answer as one of the driving rules of a foreign country says details on license should be in latin characters, so I am wondering whether my information printed in English qualifies for being in Latin?
I understand that the alphabet for the English language is not strictly English as languages such as French, Dutch and many more use the same alphabet, with few additions in other languages. Is Roman alphabet the common term to refer to this set of symbols for writing texts?
Strange noise when moving files When I move files, a small 'noise' noise comes through my headphones or speakers.  It only happens when moving files.  Is there a reason why moving files causes this slight static?  It only lasts for as long as the files are moving.  I'm not as much as annoyed as I am curious.  It is a Gigabyte board with a integrated sound card.  I'm running Windows 7.  I don't think it used to do this but I'm not quite sure. How to solve $x^3=-1$? How to solve $x^3=-1$? I got following:  $x^3=-1$   $x=(-1)^{\frac{1}{3}}$  $x=\frac{(-1)^{\frac{1}{2}}}{(-1)^{\frac{1}{6}}}=\frac{i}{(-1)^{\frac{1}{6}}}$... Using single quote by curly braces in String.format in Dynamic SOQL I'm struggling to use String.format to replace a token with a value when the token is within single quotes:  Example:  String query = String.format('SELECT Id FROM Availability WHERE Person__c = \'{0}\'', personId);   String query is equal to:  SELECT Id FROM Availability WHERE Person__c = {0}   Rather than:  SELECT Id FROM Availability WHERE Person__c = '234567890' Why is saltatory conduction in myelinated axons faster than continuous conduction in unmyelinated axons? Is there any way to automatically unwrap UV map proportionally to object or "world" size?  For example:  I've made two cubes, one is two times bigger than other (scale is applied). Then I unwrapped texture with Smart UV project which will try to span all faces on whole texture space(0 to 1) so bricks on left cube will be bigger than bricks on right cube.   But what I want to achieve is this:     In broader context:  When I import model from Archicad (in form of OBJ) all objects have UV's in some scale (so all bricks have the same size on every imported object). And when I want to create custom object in scene I have to manually scale UV's to adjust bricks size for every new object (instead of scaling to one constant parameter). php - Should I encrypt email addresses? Confused at + and ++ in TikZ I can't seem to figure out the difference between + and ++ relative coordinates in TikZ.   I understand ++. ++ specifies delta coordinates that are added to the last current point, the current point is then set to the new absolute current point (correct?):  \draw (0,0) -- ++(1,0) -- ++(0,1) means:  set Current Point to (0,0) add (1,0) to Current Point = (1,0) set Current Point to (1,0) add Current Point (1,0) to (0,1) = (1,1) set Current Point to (1,1)   I can't seem to figure out that + does, when I try it out it looks like the coordinates in the +(x,y) are absolute coordinates rather than delta coordinates, but the manual says otherwise Why Negative refractive index is negative I'm using Jabref to manage my Bibliography.  Sometimes, I put directly:     First Author et al.   when adding the article author's name in Jabref.  When compiling my .tex file, LaTeX doesn't recognize the et. al as more names. It takes it as a name/surname.  This is an example of a Bibliography entry in Jabref.  @ARTICLE{Wolf2003,     author = {Wolf, K.et al.},     title = {Compensation mechanism in tumor cell migration: mesenchymal–amoeboid     transition after blocking of pericellular proteolysis},     journal = {J.

SyntaxError: Non-ASCII character '\xa3' in file when function returns '£' How to stop apt from doing anything I am reading Boyd &amp; Vandenberghe's Convex Optimization.

Similes and Metaphors - are similes a subset of metaphors? I was wondering if there was a method to alter object settings at a set point in an animation in blender.  For example, I want to make the color of an object blue for the first 20 frames, but after 20 frames I want its color to change to green. Is there any known method of doing this? I could not find anything when I searched. What’s (not) spam? Somebody asked the following :    Clearly this is just a troll post so I (and other users) flagged it as spam. The spam flag was subsequently disputed (which I think simply means that a moderator rejected it):    Huh? Puzzled, I took another look at the list of possible flagging reasons:     I am flagging this question because         it is spam   This question is effectively an advertisement with no disclosure. It is not useful or relevant, but promotional.   it is offensive, abusive, or hate speech   This question contains content that a reasonable person would deem inappropriate for   respectful discourse.   it is a duplicate...   This question has been asked before and already has an answer.   it should be closed for another reason...   This question does not meet this site's standards and should be closed.   it is very low quality   This question has severe formatting or content problems. This question is unlikely to be salvageable through editing, and might need to be removed.   other (needs ♦ moderator attention)   This question needs a moderator's attention. Please describe exactly what's wrong.      Of these, only a few are applicable at all: “spam”, “should be closed for another reason”, “low quality” and “requires moderator attention”.  But:   it shouldn’t be closed (it has no value – it should be deleted), it’s not “low quality” (the description seems to fit actual, albeit bad, questions), and it doesn’t require moderator attention (I certainly didn’t want to bother a mod with this worthless post).   So I still think “spam” is the most fitting reason. Maybe it would help to have a more apt reason “troll post”, or maybe we could explicitly subsume this under one of the other points? How do I unlock all the other ships in the hangar? Though tangentially related to another post on MathOverflow (), the questions below are mainly out of curiosity. They may be very-well known ones with very well-known answers, but...    Suppose $\Sigma$ is a sigma-algebra over a set, $X$. For any given topology, $\tau$, on $X$ denote by $\mathfrak{B}_X(\tau)$ the Borel algebra over $X$ generated by $\tau$.     Question 1. Does there exist a topology, $\tau$, on $X$ such that $\Sigma = \mathfrak{B}_X(\tau)$?   If the answer to the previous question is affirmative, it makes sense to ask for the following too:     Question 2. Denote by ${\frak{T}}_X(\Sigma)$ the family of all topologies $\tau$ on $X$ such that $\Sigma = \mathfrak{B}_X(\tau)$ and let $\tau_X(\Sigma) := \bigcap_{\tau \in {\frak{T}}_X(\Sigma)} \tau$. Is $\Sigma = \mathfrak{B}_X({\frak{T}}_X(\Sigma))$?   Updates. Q2 was answered in the negative by Mike (). Automatically resize uploaded images Possible Duplicate:             Could large images of more then 640 pixels wide automatically be resized to reduce loading time and band width use? Not that I have a prehistoric internet connection here, but sometimes pages seem to need unnecessary time to load fully.  I just resized the image  from 179 kb down to 32 kb using a 15% compression rate. I think that is already worth it, although there have been much bigger downsizes in the past.  This feature then propably should/could be combined with , and uploading an image then would result in the following post addition:  [![enter image description here][2]][1]  [1]: http://i.stack.imgur.com/ZSBxw.gif "View &lt;image title&gt; full sized" [2]: http://i.stack.imgur.com/VXmBA.jpg "&lt;Image title&gt;"   Update:  I now understand from  that images áre resized already, but that post authors have to do some changes themselves.
