  • Tomcat does not pick up the class file - the JSP file is not displayed

    - by blueSky
    I have a Java code which is a controller for a jsp page, called: HomeController.java. Code is as follows: @Controller public class HomeController { protected final transient Log log = LogFactory.getLog(getClass()); @RequestMapping(value = "/mypage") public String home() { System.out.println("HomeController: Passing through..."); return "home"; } } There is nothing especial in the jsp page: home.jsp. If I go to this url: http://localhost:8080/adcopyqueue/mypage I can view mypage and everything works fine. Also in the tomcat Dos page I can see the comment: HomeController: Passing through... As expected. Now under the same directory that I have HomeController.java, I've created another file called: LoginController.java. Following is the code: @Controller public class LoginController { protected final transient Log log = LogFactory.getLog(getClass()); @RequestMapping(value = "/loginpage") public String login() { System.out.println("LoginController: Passing through..."); return "login"; } } And under the same place which I have home.jsp, I've created login.jsp. Also under tomcat folders, LoginController.class exists under the same folder that HomeController.class exists and login.jsp exists under the same folder which home.jsp exists. But when I go to this url: http://localhost:8080/adcopyqueue/loginpage Nothing is displayed! I think tomcat does not pick up LoginController.class b/c on the tomcat Dos window, I do NOT see this comment: LoginController: Passing through... Instead I see following which I do not know what do they mean? [ INFO] [http-8080-1 01:43:45] (AppInfo.java:populateAppInfo:34) got manifest [ INFO] [http-8080-1 01:43:45] (AppInfo.java:populateAppInfo:36) manifest entrie s 8 The structure and the code for HomeController.java and LoginController.java plus the jsp files match. I have no idea why tomcat sees one of the files and not the other? Clean build did not help. Does anybody have any idea? Any help is greatly appraciated.

  • How to check if a number is a power of 2

    - by configurator
    Today I needed a simple algorithm for checking if a number is a power of 2. The algorithm needs to be: Simple Correct for any ulong value. I came up with this simple algorithm: private bool IsPowerOfTwo(ulong number) { if (number == 0) return false; for (ulong power = 1; power > 0; power = power << 1) { // this for loop used shifting for powers of 2, meaning // that the value will become 0 after the last shift // (from binary 1000...0000 to 0000...0000) then, the for // loop will break out if (power == number) return true; if (power > number) return false; } return false; } But then I thought, how about checking if log2x is an exactly round number? But when I checked for 2^63+1, Math.Log returned exactly 63 because of rounding. So I checked if 2 to the power 63 is equal to the original number - and it is, because the calculation is done in doubles and not in exact numbers: private bool IsPowerOfTwo_2(ulong number) { double log = Math.Log(number, 2); double pow = Math.Pow(2, Math.Round(log)); return pow == number; } This returned true for the given wrong value: 9223372036854775809. Does anyone have any suggestion for a better algorithm?

  • Sending a file to uCLinux

    - by Mike
    I have a board running uClinux, and I need to send a file to it, but I'm not sure how... I have a RS232 port, and Ethernet port with an IP address at my disposal, I can telnet to the board, but uCLinux doesn't have a built in FTP client. What sort of options do I have here for transferring files from my Windows 7 (or OpenSUSE) machine(s) to this board? EDIT I just found I have a TFTP server on it: # tftp BusyBox v0.60.5 (2012.07.09-14:05+0000) multi-call binary Usage: tftp [OPTION]... HOST [PORT] But I can't find any good information on how to use TFTP. And looking around google I'm seeing it's good for loading binary images, so I'm assume anything could be sent, but I'm not sure.

  • Why can't all zeros in the host portion of IP address be used for a host?

    - by Grezzo
    I know that if I have a network 83.23.159.0/24 then I have 254 usable host IP addresses because: 83.23.159.0 (in binary: host portion all zeros) is the subnet address 83.23.159.1-254 are host addresses 83.23.159.255 (in binary: host portion all ones) is the broadcast address I understand the use for a broadcast address, but I don't understand what the subnet address is ever used for. I can't see any reason that an IP packet's destination address would be set to the subnet address, so why does the subnet itself need an address if it is never going to be the endpoint for AN IP flow? To me it seems like a waste to not allow this address to be used as a host address. To summarise, my questions are: Is an IP packet's destination ever set to the subnet IP address? If yes, in what cases and why? If no, then why not free up that address for any host to use?

  • Streaming audio not working in Android

    - by user320293
    Hi, I'm sure that this question has been asked before but I've been unable to find a solid answer. I'm trying to load a streaming audio from a server. Its a audio/aac file http://3363.live.streamtheworld.com:80/CHUMFMAACCMP3 The code that I'm using is private void playAudio(String str) { try { final String path = str; if (path == null || path.length() == 0) { Toast.makeText(RadioPlayer.this, "File URL/path is empty", Toast.LENGTH_LONG).show(); } else { // If the path has not changed, just start the media player MediaPlayer mp = new MediaPlayer(); mp.setAudioStreamType(AudioManager.STREAM_MUSIC); try{ mp.setDataSource(getDataSource(path)); mp.prepareAsync(); mp.start(); }catch(IOException e){ Log.i("ONCREATE IOEXCEPTION", e.getMessage()); }catch(Exception e){ Log.i("ONCREATE EXCEPTION", e.getMessage()); } } } catch (Exception e) { Log.e("RPLAYER EXCEPTION", "error: " + e.getMessage(), e); } } private String getDataSource(String path) throws IOException { if (!URLUtil.isNetworkUrl(path)) { return path; } else { URL url = new URL(path); URLConnection cn = url.openConnection(); cn.connect(); InputStream stream = cn.getInputStream(); if (stream == null) throw new RuntimeException("stream is null"); File temp = File.createTempFile("mediaplayertmp", ".dat"); temp.deleteOnExit(); String tempPath = temp.getAbsolutePath(); FileOutputStream out = new FileOutputStream(temp); byte buf[] = new byte[128]; do { int numread = stream.read(buf); if (numread <= 0) break; out.write(buf, 0, numread); } while (true); try { stream.close(); } catch (IOException ex) { Log.e("RPLAYER IOEXCEPTION", "error: " + ex.getMessage(), ex); } return tempPath; } } Is this the correct implementation? I'm not sure where I'm going wrong. Can someone please please help me on this.

  • How do I debug JavaScript .onlick event?

    - by user3700824
    I'm learning JavaScript but seem to be having a problem. I have a piece of code that is executed when the page is fully loaded. The function then gathers all the button elements on my HTML page. From here I loop through getting each button's title attribute and then assign an onclick event to the button that is equal to a function that writes to the console.log with the title. I have tried various ways of doing this but it is not working. Here is the JavaScript code that I'm working with. Currently all it does is loop through calling the function and logging the tile to the console.log, but this is not supposed to happen. Each time I click the button it should call the function with its title and log that. window.onload = myPageIsReady; function myPageIsReady(){ var myList = document.getElementsByTagName("button"); var myTitle = []; for(var i = 0; i < myList.length; i++){ myTitle[i] = myList[i].getAttribute("title"); myList[i].onclick = getMyTitle(myTitle[i]); }; function getMyTitle(myTitle){ console.log(myTitle); }; };

  • nginx bad gateway 502 with mono fastcgi

    - by Bradley Lederholz Leatherwood
    Hello so I have been trying to get my website to run on mono (on ubuntu server) and I have followed these tutorials almost to the letter: However when my directory is not blank fastcgi logs reveal this: Notice Beginning to receive records on connection. Error Failed to process connection. Reason: Exception has been thrown by the target of an invocation. I am not really sure what this means, and depending on what I do I can get another error that tells me the resource cannot be found: The resource cannot be found. Description: HTTP 404.

  • Can GNU sed (for Windows) handle Unicode? If so, is it a code-page/locale issue, or a switch?

    - by Peter.O
    I've been using GNU SED on and off for a couple of years now. It spins me out a bit sometimes, but it does a good job... for single-byte char sets! I now and then notice references to GNU SED being Unicode-aware, but the closest I've seen of this is its "binary" mode.. and binary is not Unicode. Can GSED process a Unicode text file at CodePoint resolution, including and especially \r\n (Windows)... and if it can, does it expect UTF-8, UTF-16, or what? and how does SED detect the encoding?

  • Can expire_logs_days be less than 1 day in MySQL?

    - by Scott
    So... yesterday I received an "after the fact email" about a campaign that has started for one of the services that I run. Now the DB server is getting hammered, hard, to the tune of about 300mb/min in binary logging for the replicate. As you could imagine, this is chewing up space at a fairly tremendous rate. My normal 7 day expiry of binary logs just isn't cutting it. I've resorted to truncating logs to just the last for 4 hours with(I'm verifying that replication is up to date with mk-heartbeat): PURGE MASTER LOGS BEFORE DATE_SUB( NOW(), INTERVAL 4 HOUR); I'm just running that from cron every few hours to weather the storm, but it made me question the minimum value for expire_logs_days. I haven't come across a value that is less than 1, but that doesn't mean that it isn't possible. http://dev.mysql.com/doc/refman/5.0/en/server-system-variables.html#sysvar_expire_logs_days gives the type as being numeric, but doesn't indicate if it's expecting integers.

  • Durandal Google Maps not showing properly

    - by user1891037
    Trying to show Google Maps using the Durandal. I'm now simply working with Durandal HTML Starter Kit so the other modules and all engine works properly. The thing is when I added the Google Map it doesn't fit the div size (the big part of div is just grey). As I understand, the problem is causing because Google Maps added before page is completely loaded. But I can't figure out how can I hook on page load event. Here is the module code: define(['knockout', 'gmaps'], function (ko, gmaps) { return { displayName: 'Google Maps', myMap: ko.observable({ lat: ko.observable(32), lng: ko.observable(10)}), activate: function () { console.log('activate'); ko.bindingHandlers.map = { init: function (element, valueAccessor, allBindingsAccessor, viewModel) { console.log('init'); var mapObj = ko.utils.unwrapObservable(valueAccessor()); var latLng = new gmaps.LatLng( ko.utils.unwrapObservable(mapObj.lat), ko.utils.unwrapObservable(mapObj.lng)); var mapOptions = { center: latLng, zoom: 5, mapTypeId: gmaps.MapTypeId.ROADMAP}; mapObj.googleMap = new gmaps.Map(element, mapOptions); } } }, attached: function() { console.log('attached'); }, compositionComplete: function() { console.log('compositionComplete'); } }; }); And a very simple HTML code: <section> <div id="gmap-canvas" data-bind="map:myMap"></div> </section> I'm loading Google Maps with async plug-in in my shell.js. It works fine. Screenshot with trouble here - http://clip2net.com/s/ibswAa P.S. div size is defined in .CSS file. P.S. I tried to use getElementById approach provided here and it's work great if placed in compositionComplete block. But when I tried to move my bindings to this block nothing happens at all. Thanks!

  • Greasemonkey failing to GM_setValue()

    - by HonoredMule
    I have a Greasemonkey script that uses a Javascript object to maintain some stored objects. It covers quite a large volume of information, but substantially less than it successfully stored and retrieved prior to encountering my problem. One value refuses to save, and I can not for the life of me determine why. The following problem code: Works for other larger objects being maintained. Is presently handling a smaller total amount of data than previously worked. Is not colliding with any function or other object definitions. Can (optionally) successfully save the problem storage key as "{}" during code startup. this.save = function(table) { var tables = this.tables; if(table) tables = [table]; for(i in tables) { logger.log(this[tables[i]]); logger.log(JSON.stringify(this[tables[i]])); GM_setValue(tables[i] + "_" + this.user, JSON.stringify(this[tables[i]])); logger.log(tables[i] + "_" + this.user + " updated"); logger.log(GM_getValue(tables[i] + "_" + this.user)); } } The problem is consistently reproducible and the logging statments produce the following output in Firebug: Object { 54,10 = Object } // Expansion shows complete contents as expected, but there is one oddity--Firebug highlights the array keys in purple instead of the usual black for anonymous objects. {"54,10":{"x":54,"y":10,"name":"Lucky Pheasant"}} // The correctly parsed string. bookmarks_HonoredMule saved undefined I have tried altering the format of the object keys, to no effect. Further narrowing down the issue is that this particular value is successfully saved as an empty object ("{}") during code initialization, but skipping that also does not help. Reloading the page confirms that saving of the nonempty object truly failed. Any idea what could cause this behavior? I've thoroughly explored the possibility of hitting size constraints, but it doesn't appear that can be the problem--as previously mentioned, I've already reduced storage usage. Other larger objects save still, and the total number of objects, which was not high already, has further been reduced by an amount greater than the quantity of data I'm attempting to store here.

  • Why is my code stopping and not returning an exception?

    - by BeckyLou
    I have some code that starts a couple of threads to let them execute, then uses a while loop to check for the current time passing a set timeout period, or for the correct number of results to have been processed (by checking an int on the class object) (with a Thread.Sleep() to wait between loops) Once the while loop is set to exit, it calls Abort() on the threads and should return data to the function that calls the method. When debugging and stepping through the code, I find there can be exceptions in the code running on the separate threads, and in some cases I handle these appropriately, and at other times I don't want to do anything specific. What I have been seeing is that my code goes into the while loop and the thread sleeps, then nothing is returned from my function, either data or an exception. Code execution just stops completely. Any ideas what could be happening? Code sample: System.Threading.Thread sendThread = new System.Threading.Thread(new System.Threading.ThreadStart(Send)); sendThread.Start(); System.Threading.Thread receiveThread = new System.Threading.Thread(new System.Threading.ThreadStart(Receive)); receiveThread.Start(); // timeout Int32 maxSecondsToProcess = this.searchTotalCount * timeout; DateTime timeoutTime = DateTime.Now.AddSeconds(maxSecondsToProcess); Log("Submit() Timeout time: " + timeoutTime.ToString("yyyyMMdd HHmmss")); // while we're still waiting to receive results & haven't hit the timeout, // keep the threads going while (resultInfos.Count < this.searchTotalCount && DateTime.Now < timeoutTime) { Log("Submit() Waiting..."); System.Threading.Thread.Sleep(10 * 1000); // 1 minute } Log("Submit() Aborting threads"); // <== this log doesn't show up sendThread.Abort(); receiveThread.Abort(); return new List<ResultInfo>(this.resultInfos.Values);

  • How should I deal with floating numbers that numbers that can get so small that the become zero

    - by Tristan Havelick
    So I just fixed an interesting bug in the following code, but I'm not sure the approach I took it the best: p = 1 probabilities = [ ... ] # a (possibly) long list of numbers between 0 and 1 for wp in probabilities: if (wp > 0): p *= wp # Take the natural log, this crashes when 'probabilites' is long enough that p ends up # being zero try: result = math.log(p) Because the result doesn't need to be exact, I solved this by simply keeping the smallest non-zero value, and using that if p ever becomes 0. p = 1 probabilities = [ ... ] # a long list of numbers between 0 and 1 for wp in probabilities: if (wp > 0): old_p = p p *= wp if p == 0: # we've gotten so small, its just 0, so go back to the smallest # non-zero we had p = old_p break # Take the natural log, this crashes when 'probabilites' is long enough that p ends up # being zero try: result = math.log(p) This works, but it seems a bit kludgy to me. I don't do a ton of this kind of numerical programming, and I'm not sure if this is the kind of fix people use, or if there is something better I can go for.

  • Has subversion lost some of my revisions in a branch?

    - by BombDefused
    I've been working on my project using a subversion branch. I've used the branching feature few times before without issue, until today. I've come to merge back into the trunk, and noticed that not everything from my branch was there. I go back to my project folder which I've been committing to the branch and look at the log messages using TortoiseSVN (the command line basic log command shows the same). See the attached image. The revision numbers go up incrementally, until revision 303 (the last trunk revision was 299). Then there are numbers missing. The latest commit, about half an hour ago was 316, but it doesn't show up in the log for the branch. Trying to commit the files again doesn't do anything. I am the only person committing to this repository at present. The missing revisions do not show up in the log for the trunk project. What's going on here. Is this a bug or am I doing something wrong? Update - the revisions do show in the repo browser (Thanks Antonio Perez), but I don't understand why they are not being included with the merge?

  • HeadJS ready for both document and script

    - by Yashua
    Current code: head.ready(function() { console.log($('.thing a').val()); }); It will sometimes fail with error that $ is not ready. I have loaded jquuery earlier with the label 'jquery'. Neither of these work: head.ready(document, function() { console.log($('.thing a').val()); }); head.ready('jquery', function() { console.log($('.thing a').val()); }); I would like to not do this if possible: head.ready(document, function() { head.ready('jquery', function() { console.log($('.thing a').val()); }); }); And also avoid refactoring current code to place that snippet at bottom of body though that I think may be the solution. Is it possible with HeadJS to define a ready call() using head.ready(), that is not placed at the bottom, that will wait for both a labeled script and the DOM to be loaded? UPDATE: the nested script doesn't actually work. I think the inner one erases/superseds the other :(

  • Magic Method __set() on a Instantiated Object

    - by streetparade
    Ok i have a problem, sorry if i cant explaint it clear but the code speaks for its self. i have a class which generates objects from a given class name; Say we say the class is Modules: public function name($name) { $this->includeModule($name); try { $module = new ReflectionClass($name); $instance = $module->isInstantiable() ? $module->newInstance() : "Err"; $this->addDelegate($instance); } catch(Exception $e) { Modules::Name("Logger")->log($e->getMessage()); } return $this; } The AddDelegate Method: protected function addDelegate($delegate) { $this->aDelegates[] = $delegate; } The __call Method public function __call($methodName, $parameters) { $delegated = false; foreach ($this->aDelegates as $delegate) { if(class_exists(get_class($delegate))) { if(method_exists($delegate,$methodName)) { $method = new ReflectionMethod(get_class($delegate), $methodName); $function = array($delegate, $methodName); return call_user_func_array($function, $parameters); } } } The __get Method public function __get($property) { foreach($this->aDelegates as $delegate) { if ($delegate->$property !== false) { return $delegate->$property; } } } All this works fine expect the function __set public function __set($property,$value) { //print_r($this->aDelegates); foreach($this->aDelegates as $k=>$delegate) { //print_r($k); //print_r($delegate); if (property_exists($delegate, $property)) { $delegate->$property = $value; } } //$this->addDelegate($delegate); print_r($this->aDelegates); } class tester { public function __set($name,$value) { self::$module->name(self::$name)->__set($name,$value); } } Module::test("logger")->log("test"); // this logs, it works echo Module::test("logger")->path; //prints /home/bla/test/ this is also correct But i cant set any value to class log like this Module::tester("logger")->path ="/home/bla/test/log/"; The path property of class logger is public so its not a problem of protected or private property access. How can i solve this issue? I hope i could explain my problem clear.

My problem is to find if the selection is in a link for to get the value of the href attribute if is set. With click the node of the link is found, with double click always the body. It is in designMode. My event-handler for click and dblclick. The vars current_selection, current_node, iframe and container are global. selection_handler:function() { current_selection = iframe.getSelection(); current_node = current_selection.anchorNode; if(current_node.nodeName == "#text") { current_node = current_node.parentNode; } $('#log').text(current_node.nodeName); }, The log shows mit for example 'body', when I click in unformated text. When I add a link with execCommand('createLink',...) the log shows 'A'. That works. When I mark the linked word with 2 click from start to end, the log shows 'A'. But with double click I always get 'body'. So I can't get the href attribute. The handler is defined in the init: init:function(options) { ... iframe = $('#wysiwyg-'+container.attr('id'))[0].contentWindow; iframe.addEventListener('dblclick',methods.selection_handler,false); iframe.addEventListener('click',methods.selection_handler,false); ... } Has somebody an idea what is wrong?

  • Adding property:value pairs from GooglemapsAPI to an existing json/javascript object

    - by Rockinelle
    I am trying to create a script that finds the closest store/location to a customer using googlemapsAPI. So I've got a json object which is a collection of store objects. Using Jquery's .each to iterate through that object, I am grabbing the driving time from the customer to each store. If it finds the directions, It copies the duration of the drive which is an object with the time in seconds and a human readable value. That appears to work, however when I try to sort through all of those store objects with the drivetime added, I cannot read the object copied from google. If I console.log the whole object, 'closest_store', It shows the values I'm looking for. When I try to read the values directly via closest_store.driveTime, Firebug is outputting undefined in the console. What am I missing here? $.getJSON('<?php echo Url::base() ?>oldservices/get_locations', {}, function(data){ $.each(data, function(index, value) { var end = data[index].address; var request = { origin: start, destination: end, travelMode: google.maps.DirectionsTravelMode.DRIVING }; directionsService.route(request, function(response, status) { //console.log(response); if (status == google.maps.DirectionsStatus.OK) { value.driveTime = response.trips[0].routes[0].duration.value; //console.log(response.trips[0].routes[0].duration.value); }; }); }); var closest_store; $.each(data, function(index, current_store) { if (index == 0) { closest_store = current_store; } else if (current_store.driveTime.value < closest_store.driveTime.value) { closest_store = value }; console.log(current_store.driveTime); } ) });

  • Logging in to website with saved username and password

    - by DGund
    One of the functions of an app I am making involves logging the user into our Campus Portal website. For ease of use, the user may enter a username and password into the app once, and it will be saved for all future log-ins. When the user clicks a button, the information will automatically be sent to log in, and the website will be displayed in a UIWebView. Let us say that the username and password are each stored in an NSString. How can I use this data to log in to this website programmatically and display the page it in a UIWebView? I know little about posting and forms, so any help is appreciated. Would something like this Stackoverflow answer help? Here's the shell of my code for this - (IBAction)btnGo:(id)sender { username = usernameField.text; password = passwordField.text; if (saveSwitch.isOn) { //Save data if the user wants AppDelegate *appDelegate = (AppDelegate *)[[UIApplication sharedApplication] delegate]; usernameSaved = username; passwordSaved = password; [appDelegate.listOfPortalCredentials replaceObjectAtIndex:0 withObject:usernameSaved]; [appDelegate.listOfPortalCredentials replaceObjectAtIndex:1 withObject:passwordSaved]; } //Insert username and password to web form, log in to portal //This is where I need help }

  • Viewing zip archive contents using 'less' on OS X.

    - by multihead
    I couldn't help but notice that the 'less' program on all of the recent distributions of Linux that I've used (Ubuntu and Gentoo in this case) allow me to view the contents of ZIP and TAR archives, while the install of 'less' that I have on OS X (and Solaris) instead produce a "foo.zip may be a binary file. See it anyway?", which proceeds to spit out the raw binary data instead of a nice file structure listing. Google has not produced much in the way of helpful results -- it's tricky to search for 'less' in this context. I downloaded and built the latest version from greenwoodsoftware.com, but even it refuses to show the contents of these archives. I didn't come across any related configure/build options either. Any ideas? Thanks!

  • Which pattern to use for logging? Dependency Injection or Service Locator?

    - by andlju
    Consider this scenario. I have some business logic that now and then will be required to write to a log. interface ILogger { void Log(string stuff); } interface IDependency { string GetInfo(); } class MyBusinessObject { private IDependency _dependency; public MyBusinessObject(IDependency dependency) { _dependency = dependency; } public string DoSomething(string input) { // Process input var info = _dependency.GetInfo(); var intermediateResult = PerformInterestingStuff(input, info); if (intermediateResult== "SomethingWeNeedToLog") { // How do I get to the ILogger-interface? } var result = PerformSomethingElse(intermediateResult); return result; } } How would you get the ILogger interface? I see two main possibilities; Pass it using Dependency Injection on the constructor. Get it via a singleton Service Locator. Which method would you prefer, and why? Or is there an even better pattern? Update: Note that I don't need to log ALL method calls. I only want to log a few (rare) events that may or may not occur within my method.

  • Shortest Distance From An Array

    - by notyou61
    I have an ajax function which returns the latitudes and longitudes of locations stored in a database. These are returned and placed in an array. A calculation is performed to return their distance from the users current location based on the latitude/longitude. I would like to return only the record with the shortest calculated distance. My code is as follows: Ajax Success // Success success: function (data) { // Obtain Log/Lat navigator.geolocation.getCurrentPosition(function(position) { // Obtain Current Position Lat/Lon glbVar.latitude = position.coords.latitude; glbVar.longitude = position.coords.longitude; // Console Log //console.log('Lat: ' + glbVar.latitude + ' Lon: ' + glbVar.longitude); // Obtain Location Distances for ( var i = 0; i < data.length; i++ ) { // Location Instances var varLocation = data[i]; // Location Distance varLocation.distance = calculateDistance(glbVar.longitude, glbVar.latitude, varLocation.locationLongitude, varLocation.locationLatitude); } // Sort Locations By Distance var sortedData = data.sort(function(a, b) { // Return Locations return a.distance - b.distance; }); // Output Results $.map(sortedData, function(item) { // Obtain Location Distance varLocationsDistance = calculateDistance(glbVar.longitude, glbVar.latitude, item.locationLongitude, item.locationLatitude); // Obtain Location Radius Assignment if (varLocationsDistance <= varLocationRadius) { // Function Return functionReturn = $({locationID : item.locationID + ', Distance : ' + varLocationsDistance + ' m'}); // Return // Function to get the Min value in Array Array.min = function( sortedData ){ functionReturn = Math.min.apply( Math, sortedData ); // console.log(functionReturn); }; } }); }); } The calculateDistance function returns the distance from the users current location and those from the database. The varLocationsDistance <= varLocationRadius "If" statement returns records within a certain distance radius (100 meters), within that statement I would like to return the shortest distance. I am a self taught amateur web developer and as a result may not have provide enough information for an answer, please let me know. Thanks,

  • Is it possible to change User's Home Directorys permission in OSX?

    - by Sosiska
    Most of your staff uses OSX as main operation system. The problem is that recently we were attacked with some odd malware: users are getting zip-file via mail, and when they open this zip file, they execute a binary keylogger malware, that is inside this zipped file. (One click is enough). We have some non-technical limitations and due this limitation we can't configure user's mail servers. But actually we have physical access to their laptops. As far as I know, there is possible to mount user's home directory without "x" (execution) permission in Linux and *BSD. So users can't run some binary file inside home directory. Is it possible to configure OS X so that user can't execute files inside /Users/?
