• How to disable/destroy forever Chrome's "print preview" option?

  - by VeryVito

  This question seems to come up a lot (pretty much every time a new version of Chrome is released). Previous answers such as these no longer apply (or don't work for Mac), however: How do I get the "old style" system print dialog for Chrome on Windows? Disable Chromes Ctrl+P handling of printing Sadly, Google seems intent on shoving this broken preview screen down our throats (The thought of someone not want to use their nonstandard, feature-poor alternative to a systemwide service is inconceivable to them, apparently), and the "disable" flag no longer seems to exist in recent versions. Anyone know how to disable it in modern versions of the browser, which no longer include this option under "chrome://flags?" (OS-X specifically?)

• How to build google breakpad

  - by Steve

  Hi, I'm totally lost on how to build Google's breakpad. There is a sln file, but it depends on a library that doesn't seem to have an associated sln. It seems to use something called gyp that I haven't figured out how to get working. I tried python gyp ..\breakpad\src\client\windows\breakpad_client.gyp and that just gives the following errors Traceback (most recent call last): File "gyp", line 18, in <module> sys.exit(gyp.main(sys.argv[1:])) File "pylib\gyp\__init__.py", line 445, in main options.circular_check) File "pylib\gyp\__init__.py", line 84, in Load depth, generator_input_info, check, circular_check) File "pylib\gyp\input.py", line 2165, in Load VerifyNoGYPFileCircularDependencies(targets) File "pylib\gyp\input.py", line 1429, in VerifyNoGYPFileCircularDependencies ' '.join(bad_files) gyp.input.CircularException: Some files not reachable, cycle in .gyp file dependency graph detected involving some or all of: ..\breakpad\src\client\windows\sender\crash_report_sender.gyp ..\breakpad\src\client\windows\h andler\exception_handler.gyp ..\breakpad\src\client\windows\breakpad_client.gyp ..\breakpad\src\client\windows\unittests\client_tests.gyp ..\breakpad\src\client\windows\crash_generation\crash_generation.gyp Which I can't make any sense out of. I also can't seem to find any documentation. Any help would be appreciated.

• zend gdata google base getting link url and parsing xml with object oriented php

  - by thrice801

  Hi, So I am using Zend frameworks Gdata extension to parse xml data from google base. http://framework.zend.com/manual/en/zend.gdata.gbase.html Working fine minus one damn important thing I cant seem to parse, the link to the actual page, because there are two elements and its returned as an array. Anyways Ive tried vardumping the array but what comes out didnt help me figure out what was going on any better. So heres the specifics of the issue. echo $entry->title->text."<br />".$entry->id->text."<br />".$entry->content->text."<br />".$entry->author[0]->name."<br />"; (the above code works fine). Now according to the documentation I thought I could get the link href by going $entry-link-text or $entry-link-url (tried both, neither worked). Anyways, Im not sure whether this is zend specific or just a gap in my OOP understanding, but any help would be much appreciated!

• Google's 'go' and scope/functions

  - by danwoods

  In one of the example servers given at golang.org: package main import ( "flag" "http" "io" "log" "template" ) var addr = flag.String("addr", ":1718", "http service address") // Q=17, R=18 var fmap = template.FormatterMap{ "html": template.HTMLFormatter, "url+html": UrlHtmlFormatter, } var templ = template.MustParse(templateStr, fmap) func main() { flag.Parse() http.Handle("/", http.HandlerFunc(QR)) err := http.ListenAndServe(*addr, nil) if err != nil { log.Exit("ListenAndServe:", err) } } func QR(c *http.Conn, req *http.Request) { templ.Execute(req.FormValue("s"), c) } func UrlHtmlFormatter(w io.Writer, v interface{}, fmt string) { template.HTMLEscape(w, []byte(http.URLEscape(v.(string)))) } const templateStr = ` <html> <head> <title>QR Link Generator</title> </head> <body> {.section @} <img src="http://chart.apis.google.com/chart?chs=300x300&cht=qr&choe=UTF- 8&chl={@|url+html}" /> <br> {@|html} <br> <br> {.end} <form action="/" name=f method="GET"><input maxLength=1024 size=70 name=s value="" title="Text to QR Encode"><input type=submit value="Show QR" name=qr> </form> </body> </html> ` Why is template.HTMLEscape(w, []byte(http.URLEscape(v.(string)))) contained within UrlHtmlFormatter? Why can't it be directly linked to "url+html"?

• jQuery UI Datepicker and Google Chrome not working

  - by zA

  Hi, I'm having some problems with jQueryUI Datepicker and Google Chrome. My datepicker is working as expected with IE8, Firefox and Safari. The problem is when clicking the datepicker connected textbox in Chrome. It gives me a crash page, "Oops, an error occurred...". On my page there's textbox with a datepicker. The datepicker is language dependent and it loads the correct language settings dynamically. The datepicker should also display the month and year dropdowns. The code is as follows $(function() {$.datepicker.setDefaults($.extend({ changeMonth: true, changeYear: true }, $.datepicker.regional['']));$('#<%= TextBoxBirthDate.ClientID %').datepicker($.datepicker.regional[$('#LabelRegionalSettings').val()]);}); If I only extend the datepicker with one option, i.e. changeYear, it works in Chrome. But if I add another option, i.e. changeMonth, the 'crash' in Chrome occurs. Is my code incorrect? If so, how do I fix it? Any help is greatly appreciated!

• AJAX Callback and Javascript class variables assignments

  - by Gianluca

  I am trying to build a little javascript class for geocoding addresses trough Google Maps API. I am learning Javascript and AJAX and I still can't figure out how can I initialize class variables trough a callback: // Here is the Location class, it takes an address and // initialize a GClientGeocoder. this.coord[] is where we'll store lat/lng function Location(address) { this.geo = new GClientGeocoder(); this.address = address; this.coord = []; } // This is the geoCode function, it geocodes object.address and // need a callback to handle the response from Google Location.prototype.geoCode = function(geoCallback) { this.geo.getLocations(this.address, geoCallback); } // Here we go: the callback. // I made it a member of the class so it would be able // to handle class variable like coord[]. Obviously it don't work. Location.prototype.geoCallback = function(result) { this.coord[0] = result.Placemark[0].Point.coordinates[1]; this.coord[1] = result.Placemark[0].Point.coordinates[0]; window.alert("Callback lat: " + this.coord[0] + "; lon: " + this.coord[1]); } // Main function initialize() { var Place = new Location("Tokyo, Japan"); Place.geoCode(Place.geoCallback); window.alert("Main lat: " + Place.coord[0] + " lon: " + Place.coord[1]); } google.setOnLoadCallback(initialize); Thank you for helping me out!

• JQueryUI with Google's CDN help

  - by TenaciousImpy

  Hi, I'm having trouble loading JQueryUI from Google's CDN. I've got an ASP.NET application that and am using this to call the scripts: <script src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.2/jquery.min.js" type="text/javascript"></script> <script src="http://ajax.googleapis.com/ajax/libs/jqueryui/1.7.2/jquery-ui.js" type="text/javascript"></script> <link href="http://ajax.googleapis.com/ajax/libs/jqueryui/1.8/themes/ui-darkness/jquery-ui.css" rel="stylesheet" type="text/css" /> <script type="text/javascript"> $(function() { $("#accordion").accordion(); }); </script> </asp:Content> I then have a test accordion: <div id="accordion"> <h3><a href="#">First header</a></h3> <div>First content</div> <h3><a href="#">Second header</a></h3> <div>Second content</div> </div> However, this doesn't work. I used Chrome's Dev tool and I get this error: Uncaught Error: The 'accordion' plugin requires Sys.scripts.ExtendedAccordion to be loaded with a call to Sys.require() first I'm also using MS' Ajax CDN in my masterpage, so could that be causing a problem?

• Serialization Performance and Google Android

  - by Jomanscool2

  I'm looking for advice to speed up serialization performance, specifically when using the Google Android. For a project I am working on, I am trying to relay a couple hundred objects from a server to the Android app, and am going through various stages to get the performance I need. First I tried a terrible XML parser that I hacked together using Scanner specifically for this project, and that caused unbelievably slow performance when loading the objects (~5 minutes for a 300KB file). I then moved away from that and made my classes implement Serializable and wrote the ArrayList of objects I had to a file. Reading that file into the objects the Android, with the file already downloaded mind you, was taking ~15-30 seconds for the ~100KB serialized file. I still find this completely unacceptable for an Android app, as my app requires loading the data when starting the application. I have read briefly about Externalizable and how it can increase performance, but I am not sure as to how one implements it with nested classes. Right now, I am trying to store an ArrayList of the following class, with the nested classes below it. public class MealMenu implements Serializable{ private String commonsName; private long startMillis, endMillis, modMillis; private ArrayList<Venue> venues; private String mealName; } And the Venue class: public class Venue implements Serializable{ private String name; private ArrayList<FoodItem> foodItems; } And the FoodItem class: public class FoodItem implements Serializable{ private String name; private boolean vegan; private boolean vegetarian; } IF Externalizable is the way to go to increase performance, is there any information as to how java calls the methods in the objects when you try to write it out? I am not sure if I need to implement it in the parent class, nor how I would go about serializing the nested objects within each object.

• What is the correct way to create dynamic javascript in ASP.net MVC2?

  - by sabbour

  I'm creating a Google Maps partial view/user control in my project that is passed a strongly typed list of objects containing latitude and longitude values. Currently, this is the code I have for the partial: <%@ Control Language="C#" Inherits="System.Web.Mvc.ViewUserControl<IEnumerable<Project.Models.Entities.Location>>" %> <!-- Place for google to put the map --> <div id="report_map_canvas" style="width: 100%; height: 728px; margin-bottom: 2px;"> </div> <script type='text/javascript'> google.load("maps", "2"); $(document).ready(initializeMap); function initializeMap() { if (GBrowserIsCompatible()) { var map = new GMap2(document.getElementById('report_map_canvas')); map.setCenter(new GLatLng(51.5, -0.1167), 2); <% foreach (var item in Model) { %> map.addOverlay(new GMarker(new GLatLng('<%= Html.Encode(item.latitude)%>','<%= Html.Encode(item.longitude)%>'),{ title: '<%= Html.Encode(String.Format("{0:F}",item.speed)) %> km/h '})); <% } %> map.setUIToDefault(); } } </script> Is it right to dynamically create the javascript file this way by looping over the list and emitting javascript? Is there a better way to do it?

• Use Excel VBA to fill out and submit Google Docs form

  - by guitarthrower

  I'm trying to do something like this post but with Excel VBA. I would like to submit a response on a google docs form each time a button is pressed on an Excel add-in. The addin will be an XLA file and written in VBA. I want to be able to collect what features the users are using. If someone has a better solution, I'm open. ---Edit--- This is the form I am trying to write to (excerpt of the code for one of the fields.) <div class="errorbox-good"> <div class="ss-item ss-item-required ss-text"> <div class="ss-form-entry"> <label for="entry_0" class="ss-q-title"> UserName <span class="ss-required-asterisk">*</span> </label> <label for="entry_0" class="ss-q-help"></label> <input type="text" id="entry_0" class="ss-q-short" value="" name="entry.0.single"> </div> </div> </div>

• Google Web Toolkit Asynchronous Call from a Service Implementation

  - by Thor Thurn

  I'm writing a simple Google Web Toolkit service which acts as a proxy, which will basically exist to allow the client to make a POST to a different server. The client essentially uses this service to request an HTTP call. The service has only one asynchronous method call, called ajax(), which should just forward the server response. My code for implementing the call looks like this: class ProxyServiceImpl extends RemoteServiceServlet implements ProxyService { @Override public Response ajax(String data) { RequestBuilder rb = /*make a request builder*/ RequestCallback rc = new RequestCallback() { @Override public void onResponseReceived(Response response) { /* Forward this response back to the client as the return value of the ajax method... somehow... */ } }; rb.sendRequest(data, requestCallback); return /* The response above... except I can't */; } } You can see the basic form of my problem, of course. The ajax() method is used asynchronously, but GWT decides to be smart and hide that from the dumb old developer, so they can just write normal Java code without callbacks. GWT services basically just do magic instead of accepting a callback parameter. The trouble arises, then, because GWT is hiding the callback object from me. I'm trying to make my own asynchronous call from the service implementation, but I can't, because GWT services assume that you behave synchronously in service implementations. How can I work around this and make an asynchronous call from my service method implementation?

• Lazy non-modifiable list

  - by mindas

  I was looking for a decent implementation of a generic lazy non-modifiable list implementation to wrap my search result entries. The unmodifiable part of the task is easy as it can be achieved by Collections.unmodifiableList() so I only need to sort out the the lazy part. Surprisingly, google-collections doesn't have anything to offer; while LazyList from Apache Commons Collections does not support generics. I have found an attempt to build something on top of google-collections but it seems to be incomplete (e.g. does not support size()), outdated (does not compile with 1.0 final) and requiring some external classes, but could be used as a good starting point to build my own class. Is anybody aware of any good implementation of a LazyList? If not, which option do you think is better: write my own implementation, based on google-collections ForwardingList, similar to what Peter Maas did; write my own wrapper around Commons Collections LazyList (the wrapper would only add generics so I don't have to cast everywhere but only in the wrapper itself); just write something on top of java.util.AbstractList; Any other suggestions are welcome.

• Essence of BiMap in Google collections

  - by littleEinstein

  I am still quite puzzled at the BiMap in Google collections/Guava. It was claimed that The two bimaps are backed by the same data; any changes to one will appear in the other. I browsed through the source code, and I found the use of delegate in ForwardingMap. But in any actually subclass of StandardBiMap, I do see the data are put into both the forward and reverse map. So what is the essence, and why it claims to have saved space by keeping only one copy of the data? Is it just the actual objects are one set, but two distinct sets of references to these objects are still needed, one set maintained in forward map, and the other in reverse map? private V putInBothMaps(K key, V value, boolean force) { boolean containedKey = containsKey(key); if (containedKey && Objects.equal(value, get(key))) { return value; } if (force) { inverse().remove(value); } else if (containsValue(value)) { throw new IllegalArgumentException( "value already present: " + value); } V oldValue = super.put(key, value); updateInverseMap(key, containedKey, oldValue, value); return oldValue; }

• Can't send an email using a google apps account with PHPMailer

  - by Chris

  I'm trying to simply send an email using my google apps account with php. I am able to send an email in a .net application using the port 587 host smtp.googlemail.com and SSL enabled. The username is my full email address. require_once('PHPMailer_v5.1\class.phpmailer.php'); try { $mail = new PHPMailer(); $mail->Mailer = 'smtp'; $mail->SMTPSecure = 'tls'; $mail->Host = $host; $mail->Port = 587; $mail->SMTPAuth = true; $mail->Username = $from; $mail->Password = $password; $mail->AddAddress($to, $to_name); $mail->From = $from; $mail->FromName = $from_name; $mail->Subject = $subject; $mail->MsgHTML($body); $mail->IsHTML(true); $mail->Send(); } catch (phpmailerException $e) { echo $e->errorMessage(); } catch (Exception $e) { echo $e->getMessage(); } Haven't been able to get this to work, but I've tried several different variations of this. $mail->SMTPSecure = 'ssl'; // Error: Could not connect to SMTP host. $mail->SMTPSecure = 'tls'; // Takes forever, then I get "this stream does not support SSL/crypto PHPMailer_v5.1\class.smtp.php" I don't care how, but I need to send an email using gmail here. It can be with this library or a different one.

• Google Web Toolkit or Microsoft Technology (Silverlight, ASP.NET)

  - by NativeByte

  We have a large code base in MFC and VB. A few applications are in .NET. All these applications interoperate with each other on the user's machine and also connect with Unix servers via sockets. Recently we have started discussing a re-write of our applications and possibility of moving a lot of these desktop applications to web (they would run in intranet). A straight forward way is rewritting them in one of the .NET technologies. But a suggestion about using Google Web tookit has popped up and the argument is that it would help creating applications that would run in a browser on both desktop and mobile devices. One of the key problem that I see is that GWT is a large abstraction over Javascript. This will require the team to learn GWT, Javascript, IDEs etc as their experience has been primarily Microsoft technologies and not Java. It would be easier for them to learn .NET technologies instead of GWT. I do not have a depth of GWT and its drawback pittfalls and do not know about a parallel Microsoft Technology that I should investigate. So I would appreciate if people here can share their views or experiences using GWT or equivalent Microsoft technology.

• DNS problems on CentOS fresh install

  - by Rick Koshi

  I'm having some DNS issues on a new box I'm installing with CentOS 6.2. I am able to look up names using nslookup, dig, or host. I am able to ping machines by name or by IP address. However, when I try other tools, such as ssh, wget, or yum, they are unable to resolve names. For example: # wget http://www.google.com --2012-03-08 14:48:06-- http://www.google.com/ Resolving www.google.com... failed: Name or service not known. wget: unable to resolve host address `www.google.com' # ssh www.google.com ssh: Could not resolve hostname www.google.com: Name or service not known # ping -c 1 www.google.com PING www.l.google.com (74.125.113.106) 56(84) bytes of data. 64 bytes from vw-in-f106.1e100.net (74.125.113.106): icmp_seq=1 ttl=46 time=43.6 ms --- www.l.google.com ping statistics --- 1 packets transmitted, 1 received, 0% packet loss, time 59ms rtt min/avg/max/mdev = 43.665/43.665/43.665/0.000 ms # host www.google.com www.google.com is an alias for www.l.google.com. www.l.google.com has address 74.125.113.99 www.l.google.com has address 74.125.113.103 www.l.google.com has address 74.125.113.104 www.l.google.com has address 74.125.113.105 www.l.google.com has address 74.125.113.106 www.l.google.com has address 74.125.113.147 My /etc/nsswitch.conf file is the default, including this (standard) line: hosts: files dns /etc/resolv.conf is as set up by DHCP: ; generated by /sbin/dhclient-script nameserver 192.168.1.254 192.168.1.254 is a working DNS server (my DSL modem, working for years with other machines) Anyone know why ping would work, but ssh/wget would fail? Per NcA's suggestion, I tried changing /etc/resolv.conf to point to 8.8.8.8. Oddly enough, this does make it work. Obviously, my DSL modem is responding to DNS requests in some way that some parts of Linux's resolution system don't like. Looking at the tcpdump, I am unable to see what the difference is. Certainly, both servers are sending the same addresses. Here's the output from tcpdump -nn -X with the server set to the DNS server on the DSL modem. It's clearly replying with the correct addresses, but ssh/wget don't seem happy with it for some reason: 15:53:52.133580 IP 192.168.1.254.53 > 192.168.1.2.54836: 33157 7/0/0 CNAME www.l.google.com., A 74.125.115.105, A 74.125.115.106, A 74.125.115.147, A 74.125.115.99, A 74.125.115.103, A 74.125.115.104 (148) 0x0000: 4500 00b0 e33a 0000 ff11 53b1 c0a8 01fe E....:....S..... 0x0010: c0a8 0102 0035 d634 009c 7528 8185 8180 .....5.4..u(.... 0x0020: 0001 0007 0000 0000 0377 7777 0667 6f6f .........www.goo 0x0030: 676c 6503 636f 6d00 0001 0001 c00c 0005 gle.com......... 0x0040: 0001 0007 acd0 0008 0377 7777 016c c010 .........www.l.. 0x0050: c02c 0001 0001 0000 0001 0004 4a7d 7369 .,..........J}si 0x0060: c02c 0001 0001 0000 0001 0004 4a7d 736a .,..........J}sj 0x0070: c02c 0001 0001 0000 0001 0004 4a7d 7393 .,..........J}s. 0x0080: c02c 0001 0001 0000 0001 0004 4a7d 7363 .,..........J}sc 0x0090: c02c 0001 0001 0000 0001 0004 4a7d 7367 .,..........J}sg 0x00a0: c02c 0001 0001 0000 0001 0004 4a7d 7368 .,..........J}sh 15:53:52.135669 IP 192.168.1.254.53 > 192.168.1.2.54836: 65062- 0/0/0 (32) 0x0000: 4500 003c e33b 0000 ff11 5424 c0a8 01fe E..<.;....T$.... 0x0010: c0a8 0102 0035 d634 0028 98f9 fe26 8000 .....5.4.(...&.. 0x0020: 0001 0000 0000 0000 0377 7777 0667 6f6f .........www.goo 0x0030: 676c 6503 636f 6d00 001c 0001 gle.com.....

• In this example, would Customer or AccountInfo properly be the entity group parent?

  - by Badhu Seral

  In this example, the Google App Engine documentation makes the Customer the entity group parent of the AccountInfo entity. Wouldn't AccountInfo encapsulate Customer rather than the other way around? Normally I would think of an AccountInfo class as including all of the information about the Customer. import javax.jdo.annotations.IdGeneratorStrategy; import javax.jdo.annotations.PersistenceCapable; import javax.jdo.annotations.Persistent; import javax.jdo.annotations.PrimaryKey; import com.google.appengine.api.datastore.Key; import com.google.appengine.api.datastore.KeyFactory; @PersistenceCapable public class AccountInfo { @PrimaryKey @Persistent(valueStrategy = IdGeneratorStrategy.IDENTITY) private Key key; public void setKey(Key key) { this.key = key; } } // ... KeyFactory.Builder keyBuilder = new KeyFactory.Builder(Customer.class.getSimpleName(), "custid985135"); keyBuilder.addChild(AccountInfo.class.getSimpleName(), "acctidX142516"); Key key = keyBuilder.getKey(); AccountInfo acct = new AccountInfo(); acct.setKey(key); pm.makePersistent(acct);

• Android Maps: Installation error: INSTALL_FAILED_MISSING_SHARED_LIBRARY

  - by AP257

  I'm trying to use Android Maps, following the instructions in Hello MapView. I've added <uses-library android:name="com.google.android.maps" /> in the Manifest, and I'm building against the 'Google APIs' target, which claims to be API version 7. So I don't think I'm doing anything obviously wrong, but the project refuses to build with this error: [2010-12-22 13:34:32 - FMS]Installing FMS.apk...

Can anyone help?

• GSM Cell Towers Location & Triangulation Algorithm (Similar to OpenCellID / Skyhook / Google's MyLocation)

  - by ranabra

  Hi all, assuming I have a Fingerprint DB of Cell towers. The data (including Long. & Lat. CellID, signal strength, etc) is achieved by 'wardriving', similar to OpenCellID.org. I would like to be able to get the location of the client mobile phone without GPS (similar to OpenCellID / Skyhook Wireless/ Google's 'MyLocation'), which sends me info on the Cell towers it "sees" at the moment: the Cell tower connected to, and another 6 neighboring cell towers (assuming GSM). I have read and Googled it for a long time and came across several effective theories, such as using SQL 2008 Spatial capabilities, or using an euclidean algorithm, or Markov Model. However, I am lacking a practical solution, preferably in C# or using SQL 2008 :) The location calculation will be done on the server and not on the client mobile phone. the phone's single job is to send via HTTP/GPRS, the tower it's connected to and other neighboring cell towers. Any input is appreciated, I have read so much and so far haven't really advanced much. Thanx

• SEO google keyword position tools?

  - by Peterl86

  Hi guys, I want to check our google postions for several keywords every day and make a note in a spreadseet. At the moment, we have a student doing it but it's a rubbish job and it doesn't seem fair on them! Are there any tools available to automate this process? I have tried rankchecker by seobook.com, but although that should be exactly what im looking for when i set scheduled tasks in that, it doesnt work. Any tips would be appreciated, thanks! peter EDIT: Liam has suggested a Python script to do this, which unfortunately isnt something I'm very familiar with! If anyone knows of a good tutorial or something to help us with this, that would be brilliant. Update: Found a php script at seoscript.net which looks like a step in the right direction. But I cant get it to work! I get this error. Anyone more knowledgabe than me know how to fix that? I have PEAR installed. thanks again, Peter

• Reverse geocode street name and city as text

  - by Taylor Satula

  Hello, I have been having some trouble finding a good way to output just the street name and city as text (Infinite Loop, Cupertino shown here) that can be displayed in my iPhone app. This needs to be able to dynamically change as you change streets and city. I don't have the slightest idea of how to do this, I hope someone can help. I have attached a very rough image of what I am trying to acheave. I have found this (http://code.google.com/apis/maps/documentation/javascript/services.html#Geocoding) for google maps about how to reverse geocode using javascript, but what I do not understand is how this would be done in a iPhone development setting. I work in web design and I see how it would be done in HTML but I am very new to iPhone development and don't have the slightest clue of how it would be done here. If someone could spell out how to do this I would be extremely grateful. I cannot seem to find what I am looking for by searching Google.

• google maps call within a For Loop not returning distance

  - by Richard Reddy

  Hi, I am calling google maps within a for loop in my javascript as I have mulitple routes that need to be costed separately based on distances. Everything works great except that the distance is only returned for one of the routes. I have a feeling that it is something to do with the way I have the items declared within the ajax call for the maps. Any ideas what could be the issue from the code below? for (var i = 1; i <= numJourneys; i++) { var mapContainer = 'directionsMap' + i; var directionContainer = $('#getDistance' + i); $.ajax({ async: false, type: "POST", url: "Journey/LoadWayPoints", data: "{'args': '" + i + "'}", contentType: "application/json; charset=utf-8", dataType: "json", success: function (msg) { if (msg.d != '[]') { var map = new GMap2(document.getElementById(mapContainer)); var distance = directionContainer; var wp = new Array(); //routes var counter = 0; $.each(content, function () { wp[counter] = new GLatLng(this['Lat'], this['Long']); counter = counter + 1; }); map.clearOverlays(); map.setCenter(wp[0], 14); // load directions directions = new GDirections(map); GEvent.addListener(directions, "load", function () { alert(directions.getDistance()); //directionContainer.html(directions.getDistance().html); }); directions.loadFromWaypoints(wp, { getSteps: true }); } } }); }

• Problem with poor font rendering with CSS3 transitions, jQuery, & Google Fonts

  - by Justin

  In Firefox, there is no problem. Here's an image: http://cl.ly/3R0L1q3P1r11040e3T1i In Safari, the text is rendering poorly: http://cl.ly/0a1101341r2E1D2d1W46 In IE7 & IE8, it's much worse, but I don't have a picture. Sorry :( I'm using Isotope jQuery plugin, and the CSS3 transitions seem to cause the poor font-rendering. I'm also using Google Font API. Here's what the CSS transitions for Isotope are written as: /**** Isotope CSS3 transitions ****/ .isotope, .isotope .isotope-item { -webkit-transition-duration: 0.8s; -moz-transition-duration: 0.8s; transition-duration: 0.8s; } .isotope { -webkit-transition-property: height, width; -moz-transition-property: height, width; transition-property: height, width; } .isotope .isotope-item { -webkit-transition-property: -webkit-transform, opacity; -moz-transition-property: -moz-transform, opacity; transition-property: transform, opacity; } I appreciate any help with this. Looks great in Firefox! Thanks!

• How do I create a hyperlink in java?

  - by Justin984

  I'm going through the google app engine tutorials at https://developers.google.com/appengine/docs/java/gettingstarted/usingusers I'm very new to google app engine, java and web programming in general. So my question is, at the bottom of the page it says to add a link to allow the user to log out. So far I've got this: public void doGet(HttpServletRequest req, HttpServletResponse resp) throws IOException { UserService userService = UserServiceFactory.getUserService(); User user = userService.getCurrentUser(); if(user != null){ resp.setContentType("text/plain"); resp.getWriter().println("Hello, " + user.getNickname()); String logoutLink = String.format("<a href=\"%s\">Click here to log out.</a>", userService.createLogoutURL(req.getRequestURI())); resp.getWriter().println(logoutLink); }else { resp.sendRedirect(userService.createLoginURL(req.getRequestURI())); } } However instead of a link, the full string is printed to the screen including the tags. When I look at the page source, I have no tags or any of the other stuff that goes with a webpage. I guess that makes sense considering I've done nothing to output any of that. Do I just do a bunch of resp.GetWriter().println() statements to output the rest of the webpage, or is there something else I don't know about? Thanks!
