Should I get into the schengen territory, normally with visas type c which is generally 3 months.  How do I go about renewals? Do I have to return home or do I go to another schengen territory to renew the visas
My daughter applied at the Italian Consulate in Philadelphia, and they gave her two entries for 20 days (we thought it was for 20 days each entry). She was in Italy 12 days, then went to England for 1 week and flew to Venice to take a 10-day cruise. She couldn't make it because they said she has only 8 remaining days, but she still has a land tour already paid this week.  What can she do? Can she extend the Schengen visa for 12 more days? Right now, she is in Madrid, but next week she has to fly from Barcelona to Paris to start with the tour. What would happen if she decides to take the tour with the expired visa? She is a US permanent resident.
What is the smallest positive integer $n$, such that there exist positive integers $a$ and $b$, with $b$ obtained from $a$ by a rearrangement of its digits, so that   $a – b = 11\dots 1$ (The number of '$1$'s equal to $n$)?   Is there any example that can satisfy the equation? "Unable to locate package" while trying to install packages with APT When I try to install any package through the command line, I get an error.   $ sudo apt-get install &lt;package&gt; Reading package lists...

Any ideas? Who fired the shot and what is the symbolism in firing shot right next to Lucas at the end of the movie? At the end of , during the deer hunt, there’s a shot fired right next to Lucas (deliberately missing the shot).   Who fired the shot? Is it Theo's son? What is the meaning of that scene? Is someone warning Lucas that he made a mistake and definitely, Lucas will be punished in the future? Windows update doesn't progress beyond 0 KB 0% I want to use a very long USB cable to place a webcam in a different room. The maximum length that I found was five meters.

Bob can no longer user secp256k1 but he only uses ed25519 instead.  Is there a secure algorithm that Bob can use to derive an ed25519 pubkey from original Alice's secp256k1 pub key and also Alice can derive the matching ed25519 private key from her original secp256k1 private key such that they can communicate securely via ed25519 encrypted messages?  Thanks! Non-finite clause complementation of complex transitive verbs This question has been bothering me for a while. It came up when I was reading Chapter 16 of "A Comprehensive Grammar of the English Language."   How to explain the grammatical structure of the following four sentences?    "We knew him to be a spy." "I saw her leave the room." "I heard someone shouting." "I got the watch repaired."    What category do the four non-finite clauses in boldface fall into? They do not seem to fall into any of relative, nominal, comparative and adverbial clauses. Adding Layer using esriRequest Response in ArcGIS API for JavaScript? For various reasons I need to add layers to a map object using a response returned by an esriRequest to an ArcGIS Server. One reason being the data will change constantly and hard coding FeatureLayer URLs would prove inefficient.  I have successfully been able to return a JSON object containing attribution that appears to be the same data one would see on the layers REST node.     maps = [];  require([     "esri/map", "esri/layers/FeatureLayer",      "esri/dijit/Print", "esri/tasks/PrintTemplate", "esri/request",      "esri/config","esri/dijit/BasemapToggle",      "dojo/_base/array", "dojo/dom", "dojo/parser",  "dojo/domReady!"  ], function (Map, FeatureLayer,Print, PrintTemplate, esriRequest,      esriConfig,BasemapToggle,arrayUtils, dom, parser){  parser.parse();  console.log("Map Start");  esriConfig.defaults.io.proxyUrl = "http://........./proxy.ashx";  maps.addRespLyrs = function addRespLyrs (layer) {     if (layer.type == "Feature layer") {         console.log(layer.name);         maps.map.addLayer(layer);     } };   maps.handleMapInfo = function handleMapInfo (resp) {     console.log("handleMapInfo called");     maps.layers = resp.layers;     console.log(maps.layers);     for (i in maps.layers) {         var layer = maps.layers[i];         maps.addRespLyrs(layer);     } };  maps.layerRequest = function layerRequest () {     var mapInfo = esriRequest({         "url": "https://........./Application Name/MapServer/layers",         "content" : {"f":"json"},         "handleAs" : "json",         "callbackParamName" : "callback"     });     mapInfo.then(maps.handleMapInfo); };  maps.map = new Map("cpCentCent", {     basemap:"topo",     center: [-98.5795, 39.8282],     zoom: 5 });   console.log("Map End");   When attempting to add the data using the addLayer() method I recieve an error thrown from deep with in esri's API.      init.js:199 TypeError: a.id.match is not a function(…) "TypeError: a.id.match is not a function   Any thoughts as to what could be going wrong here or how to create a layer from my JSON? Should I remove non-significant variables from my regression model I have run a multiple linear regression using stepwise regression to select the best model, however the best model returned has a non-significant variable. When I remove this the AIC value goes up indicating the model without the significant variable is a worse fit. Should I remove the non-significant predictor or should I leave it in as it is a better model? Counting points in polygons using QGIS What exactly is "pressure", and what's its relation to force? Single quote within double quotes and the Bash reference manual In section 3.1.2.3  titled Double Quotes, the Bash manual says:      Enclosing characters in double quotes (‘"’) preserves the literal   value of all characters within the quotes, with the exception of ‘$’,   ‘`’, ‘\’, and, when history expansion is enabled, ‘!’.   At the moment I am concerned with the single quote(').  It's special meaning, described in the preceding section, section 3.1.2.2 is:     Enclosing characters in single quotes (') preserves the literal   value of each character within the quotes. A single quote may not   occur between single quotes, even when preceded by a backslash.   Combining the two expositions,    echo "'$a'"   where variable a is not defined (hence $a = null string), should print $a on the screen, as '', having it's special meaning inside, would shield $ from the special interpretation. Instead, it prints ''. Why so? Custom URL Hack - anybody know how can i find the fields IDs from "User" object? I'm new in custom URL hacking.  I am trying to write a custom URL in a custom button. It is suppose to clone the User record, and while doing so, I want some user fields to be cleared. However, I need help identifying those fields IDs (e.g. Email, Name, etc).  How can i refer these fields when writing the custom URL code? BeanFactory vs ApplicationContext I'm pretty new to the Spring Framework, I've been playing around with it and putting a few samples apps together for the purposes of evaluating Spring MVC for use in an upcoming company project. So far I really like what I see in Spring MVC, seems very easy to use and encourages you to write classes that are very unit test-friendly.  Just as an exercise, I'm writing a main method for one of my sample/test projects. One thing I'm unclear about is the exact differences between BeanFactory and ApplicationContext - which is appropriate to use in which conditions?  I understand that ApplicationContext extends BeanFactory, but if I'm just writing a simple main method, do I need the extra functionality that ApplicationContext provides? And just exactly what kind of extra functionality does ApplicationContext provide?  In addition to answering "which should I use in a main() method", are there any standards or guidelines as far as which implementation I should use in such a scenario? Should my main() method be written to depend on the bean/application configuration to be in XML format - is that a safe assumption, or am I locking the user into something specific?  And does this answer change in a web environment - if any of my classes needed to be aware of Spring, are they more likely to need ApplicationContext?  Thanks for any help. I know a lot of these questions are probably answered in the reference manual, but I'm having a hard time finding a clear breakdown of these two interfaces and the pros/cons of each without reading thru the manual with a fine-tooth comb. What are the technical differences between using a DSLR viewfinder and live view? The earlier question  asks for practical advantages of optical viewfinders. But what's the technical difference, and why does a camera behave differently in each mode?  For example, on my Nikon D5100:   Slower auto-focus — I saw this explained in the related issue, but just partially: "The other major drawback of live view is that because it requires the mirror to be locked up, it means that the auto focusing mechanism is unavailable."  option not available. No . The manual says that it's dangerous to shoot direct light, when it's on live-view. There's no range finder available.   Why are all these things different?  Live view also has some advantages, like:   automatic scene selection grid lines on the screen other smaller things, like possibly easier operation on a tripod where the viewfinder might be inconvenient to look through   Some of these things, like the tripod operation, are natural. But are there technical reasons the others can't be done with an optical finder? Are there other advantages enabled by live view for technical reasons? Dropping z dimension programmatically I'd like to find a Windows batch counterpart to Bash's $@ that holds a list of all arguments passed into a script.   Or I have to bother with shift? Whenever I play a PC game with the directional keys, I can only press two buttons at a time.  For instance if I am playing a shooter like R-Type, I cannot hold down the fire button while moving diagonally at the same time.  The computer simply ignores the extra button press.  How do I remove this limit so I can shoot while moving diagonally?  This limitation seems to apply for every game.  I am running Windows 7 if it makes any difference.  I noticed the same problem back when I used Windows XP.
