  • So now Google has said no to old browsers when can the rest of us follow suit?

    - by Richard
    Google recently announced that they will no longer support older browsers on Aug 1st: http://www.bbc.co.uk/news/technology-13639875 http://gmailblog.blogspot.com/2011/06/our-plans-to-support-modern-browsers.html For this reason, soon Google Apps will only support modern browsers. Beginning August 1st, we’ll support the current and prior major release of Chrome, Firefox, Internet Explorer and Safari on a rolling basis. Each time a new version is released, we’ll begin supporting the update and stop supporting the third-oldest version. There is nothing worse than looking at the patching of code that takes place to support older browsers. If we could all move towards a standards only web (I'm looking at you IE9) then surely we could spend more time programming good web apps and less trying to make them run equally on terrible non standards compliant older browsers. So when can the rest of us expect to be able to tell our clients that we no longer support older browsers? Because it seems that large corporates will continue to run older browsers and even if google chrome frame can be installed without admin privileges (it's coming soon, currently in beta) we can't expect all users to be motivated to do this. I appreciate any thoughts.

  • If I want to dual-boot Ubuntu with another OS, what partitioning method should I use?

    - by Jay
    I have Ubuntu running as a vm in VirtualBox at the moment, but in the future, if I want to dual-boot it with Windows or another OS installed on my hard-drive, what partitioning method should I use to make room for it? 1)Manually partition my hard drive via disk management in Windows (or the equivalent in another OS), making appropriate room for the main partition upon which Ubuntu will be installed and swap space; 2)Partition via the Ubuntu installer options; 3)Use gparted or another free tool like it. I am uncertain as to why I would want to use one over the other. Lastly, am I correct to think that it would be the acme of foolishness to try to partition drives within a virtual machine (since that partitioning would be inherently limited to the limitations set upon it by the virtualization software, e.g., VirtualBox)? Thanks! P.S. Oh, and I am also planning on not modifying the MBR of Windows if I ever do dual-boot with Ubuntu, using instead a piece of free software (like easyBCD or something) to avoid the headaches of Grub being overwritten by a Windows update.

  • Should I be concerned that I can't program very fast without Google? [closed]

    - by seth
    Possible Duplicate: Google is good or bad for programmer? I'm currently in college to be a software engineer, and one of the main principles taught to us is how to learn for ourselves, and how to search the web when we have a doubt. This leads to a proactive attitude - when I need something, I go get it. Recently, I started wondering how much development would I be able to do without internet access and the answer bugged me quite a bit. I know the concept of the languages and how to use them, but I was amazed by how "slow" things were without having the Google to help in the development. Most of the problems I have are related to specific syntax. For example, reading and writing to a file in Java. I have done this about a dozen times in my life, yet every time I need to do it, I end up googling "read file java" and refreshing my memory. I completely understand the code and fully understand what it does, but I am sure that without Google it would take me a few tries to get the code correct. Is this normal? Should I be worried and try to change something in my programming behaviour?

  • Where do I read more about building an architecture like Google has? [on hold]

    - by user107148
    I want to develop a program that watches and traverses a rather big network for data. This data should then be available to search through with my program, maybe through a web interface or something. My intuitive thought at the moment is to build an architecture kind of like the one Google has. One "front-end" (the Google Search page) which is essentially a regular web application and one "back-end" (which in Google's case traverses the web). Now for the hard part: If I decide to make such a system, how should communication be done between these parts? One idea I had is to use some kind of database that both the back-end and front-end can access, but then comes the issues of concurrent writes and reads. Another issue with just using a database to communicate is that it makes it hard to "notify" the other part when something changes. Let's say that I want the "front-end" part to push changes to the UI when a change is noticed in the back-end. Then the back-end would have to have some way of notifying the front-end of this.

  • While in CMD shell, copying files from host OS to guest VM locks files (VMware Player/Workstation)

    - by Malcolm
    We're running the latest versions of VMWare Player and Workstation for Windows. The following behavior is identical across both products. Problem: We open a CMD prompt in our guest OS (XP, Vista, Windows 7) and copy files from our host OS using the standard CMD shell copy command: copy z:\C$\testfiles The copy completes successfully, but from that point forward, all the files that were copied to our guest OS are now LOCKED on our host OS. This does not happen if we use Windows Explorer to copy files - it only happens when files are copied via the CMD shell. As mentioned at the start of this question, this behavior is reproducible in both VMWare Player and VMWare Workstation across multiple machines and multiple guest OS's. I've googled for a workaround, but without success. Any ideas appreciated. Malcolm

  • Should I use `import os.path` or `import os`?

    - by Denilson Sá
    According to the official documentation, os.path is a module. Thus, what is the preferred way of importing it? # Should I always import it explicitly? import os.path Or... # Is importing os enough? import os Please DON'T answer "importing os works for me". I know, it works for me too right now. What I want to know is any official recommendation about this issue. So, if you answer this question, please post your references.

  • Managing highly repetitive code and documentation in Java

    - by polygenelubricants
    Highly repetitive code is generally a bad thing, and there are design patterns that can help minimize this. However, sometimes it's simply inevitable due to the constraints of the language itself. Take the following example from java.util.Arrays: /** * Assigns the specified long value to each element of the specified * range of the specified array of longs. The range to be filled * extends from index <tt>fromIndex</tt>, inclusive, to index * <tt>toIndex</tt>, exclusive. (If <tt>fromIndex==toIndex</tt>, the * range to be filled is empty.) * * @param a the array to be filled * @param fromIndex the index of the first element (inclusive) to be * filled with the specified value * @param toIndex the index of the last element (exclusive) to be * filled with the specified value * @param val the value to be stored in all elements of the array * @throws IllegalArgumentException if <tt>fromIndex &gt; toIndex</tt> * @throws ArrayIndexOutOfBoundsException if <tt>fromIndex &lt; 0</tt> or * <tt>toIndex &gt; a.length</tt> */ public static void fill(long[] a, int fromIndex, int toIndex, long val) { rangeCheck(a.length, fromIndex, toIndex); for (int i=fromIndex; i<toIndex; i++) a[i] = val; } The above snippet appears in the source code 8 times, with very little variation in the documentation/method signature but exactly the same method body, one for each of the root array types int[], short[], char[], byte[], boolean[], double[], float[], and Object[]. I believe that unless one resorts to reflection (which is an entirely different subject in itself), this repetition is inevitable. I understand that as a utility class, such high concentration of repetitive Java code is highly atypical, but even with the best practice, repetition does happen! Refactoring doesn't always work because it's not always possible (the obvious case is when the repetition is in the documentation). Obviously maintaining this source code is a nightmare. A slight typo in the documentation, or a minor bug in the implementation, is multiplied by however many repetitions was made. In fact, the best example happens to involve this exact class: Google Research Blog - Extra, Extra - Read All About It: Nearly All Binary Searches and Mergesorts are Broken (by Joshua Bloch, Software Engineer) The bug is a surprisingly subtle one, occurring in what many thought to be just a simple and straightforward algorithm. // int mid =(low + high) / 2; // the bug int mid = (low + high) >>> 1; // the fix The above line appears 11 times in the source code! So my questions are: How are these kinds of repetitive Java code/documentation handled in practice? How are they developed, maintained, and tested? Do you start with "the original", and make it as mature as possible, and then copy and paste as necessary and hope you didn't make a mistake? And if you did make a mistake in the original, then just fix it everywhere, unless you're comfortable with deleting the copies and repeating the whole replication process? And you apply this same process for the testing code as well? Would Java benefit from some sort of limited-use source code preprocessing for this kind of thing? Perhaps Sun has their own preprocessor to help write, maintain, document and test these kind of repetitive library code? A comment requested another example, so I pulled this one from Google Collections: com.google.common.base.Predicates lines 276-310 (AndPredicate) vs lines 312-346 (OrPredicate). The source for these two classes are identical, except for: AndPredicate vs OrPredicate (each appears 5 times in its class) "And(" vs Or(" (in the respective toString() methods) #and vs #or (in the @see Javadoc comments) true vs false (in apply; ! can be rewritten out of the expression) -1 /* all bits on */ vs 0 /* all bits off */ in hashCode() &= vs |= in hashCode()

  • dynamically drawing polylines on googlemaps using php/mysql

    - by arc
    Hi. I am new to the googlemaps API. I have written a small app for my mobile phone that periodically updates its location to an SQL databse. I would like to display this information on a googlemap in my browser. Ideally i'd like to then poll the database periodically and if any new co-ords have arrived, add them to the line. Best way of describing it is this; http://tiny.cc/HEIa0 In a quest to get to there, i've started on the documents on google and been modifying them to try and acheive what I want. It doesn't work - and i don't know enough to know why. I would love some advice as to why, and any pointers towards my ultimate goal would be very much welcomed. Google Maps AJAX + MySQL/PHP Example <script type="text/javascript"> //<![CDATA[ function load() { if (GBrowserIsCompatible()) { var map = new GMap2(document.getElementById("map")); map.addControl(new GSmallMapControl()); map.addControl(new GMapTypeControl()); map.setCenter(new GLatLng(47.614495, -122.341861), 13); GDownloadUrl("phpsqlajax_genxml.php", function(data) { var xml = GXml.parse(data); var line = []; var markers = xml.documentElement.getElementsByTagName("points"); for (var i = 0; i < points.length; i++) { var point = points.item(i); var lat = point.getAttribute("lat"); var lng = point.getAttribute("lng"); var latlng = new GLatLng(lat, lng); line.push(latlng); if (point.firstChild) { var station = point.firstChild.nodeValue; var marker = createMarker(latlng, station); map.addOverlay(marker); } } var polyline = new GPolyline(line, "#ff0000", 3, 1); map.addOverlay(polyline); }); } //]]> My php file is generating the following XML; <?xml version="1.0" encoding="UTF-8" ?> <points> <point lng="-122.340141" lat="47.608940"/> <point lng="-122.344391" lat="47.613590"/> <point lng="-122.356445" lat="47.624561"/> <point lng="-122.337654" lat="47.606365"/> <point lng="-122.345673" lat="47.612823"/> <point lng="-122.340363" lat="47.605961"/> <point lng="-122.345467" lat="47.613976"/> <point lng="-122.326584" lat="47.617214"/> <point lng="-122.342834" lat="47.610126"/> </points> I have successfully worked through this; http://code.google.com/apis/maps/articles/phpsqlajax.html before attempting to customise the code.

  • wave.getState() returns null

    - by RMorrisey
    When trying to call wave.getState() in my Google Wave gadget, I get back null (no state object). How can I initialize the Wave state object? I am working in the Wave Sandbox. My ModulePrefs contains the following: <Require feature="wave" /> <Require feature="rpc"/> I got the "rpc" feature from some google groups post when searching for a fix, but it doesn't seem to be any help. The gadget contains a jQuery plugin, which defines the classes I use (not shown), attaches an event handler to the link that shows up in edit mode, and sets up the callback methods with the google wave gadget initializer: $.fn.extend({ $.gork.InitPass.newButtonClick = function newButtonClick() { var jer = new $.gork.InitPass.Player('Jeremias', 12, 2); var delta = {}; delta[jer.name] = jer.serialize(); wave.getState().submitDelta(delta); }; $.gork.InitPass.modeCallback = function modeCallback() { var state = wave.getState(); var mode = wave.getMode(); $.gork.InitPass.getContainer().ipCombatState(state, (mode == wave.Mode.EDIT)); }; $.gork.InitPass.stateCallback = function stateCallback() { $.gork.InitPass.getContainer().ipCombatState( wave.getState(), (wave.getMode() == wave.Mode.EDIT)); alert('state'); }; $.gork.InitPass.init = function init() { if (wave && wave.isInWaveContainer()) { var mode = wave.getMode(); $('.gork-ip-container').ipCombatState(null, (mode == wave.Mode.EDIT)); wave.setModeCallback($.gork.InitPass.modeCallback); wave.setStateCallback($.gork.InitPass.stateCallback); } }; })(jQuery); gadgets.util.registerOnLoadHandler($.gork.InitPass.init); $(function ready() { $.gork.InitPass.getContainer().find('.gork-ip-edit .addSection a.newButton').click( $.gork.InitPass.newButtonClick); }); So there are two main pieces of functionality here: When the mode changes, ipCombatState(...) is called. This changes the visual appearance of the gadget when the user puts the gadget in Edit mode (CTRL+E), by hiding the view DIV and displaying the edit DIV. The newButtonClick callback (which is attached to the link "a.newButton" in the edit container) is supposed to add Jeremias (Nate's Shadowrun character) to the gadget state, so that he'll be appear as a table row in edit mode. I have verified that the initializer method is called, and the view/edit mode switch works just fine (except the state is null). When I click on the new button link (the link at the bottom in edit mode), and trigger the newButtonClick handler, I get an error because wave.getState() also returns null. How can I initialize the wave state so that I can work with it? The purpose of my gadget will be to keep track of combat initiative order in a Shadowrun tabletop game (4th Ed). You can test it out in Wave and see what I have so far: http://gorkwobble.herobo.com/wave/init-pass.xml The actual javascript code is externalized to: http://gorkwobble.herobo.com/wave/init-pass.js P.S. If any Shadowrun players read this, and want to hear about it when I get the gadget working, leave a comment and I'll wave you.

  • JSR-299 CDI / Weld vs. Google Guice

    - by deamon
    Weld, the JSR-299 Contexts and Dependency Injection reference implementation, considers itself as a kind of successor of Spring and Guice. CDI was influenced by a number of existing Java frameworks, including Seam, Guice and Spring. However, CDI has its own, very distinct, character: more typesafe than Seam, more stateful and less XML-centric than Spring, more web and enterprise-application capable than Guice. But it couldn't have been any of these without inspiration from the frameworks mentioned and lots of collaboration and hard work by the JSR-299 Expert Group (EG). http://docs.jboss.org/weld/reference/latest/en-US/html/1.html What makes Weld more capable for enterprise application compared to Guice? Are there any advantages or disadvantages compared to Guice? What do you think about Guice AOP compared to Weld interceptors? What about performance?

  • How do I store more information in a marker?

    - by Sebastian
    Hello, I'm using Google Maps v3 and I build in the server side a json collection of location data. So when I receive that, I iterate through that collection and create a marker object for each and every one of them. For each of these markers, I bind them with the click event, so when the user clicks on a marker in the map, it displays an infoWindow with data related to the associated location. I have an array to store all the location got from the server that holds the retrieved json objects and their corresponding marker. The problem is that, even when I have an array that I can reference or iterate through, I need to not only get the marker object when the user clicks on them, but also the location object, that stores more information. I tried to mantain this array of objects and reference it from the calling object without success, because the function is called by the marker and not the location object. So I thought if it's possible to store more information in the google maps marker object like using a general purpose field. Please let me know if more information is needed. Thanks!

  • How do I get google protocol buffer messages over a socket connection without disconnecting the clie

    - by Dan
    Hi there, I'm attempting to send a .proto message from an iPhone application to a Java server via a socket connection. However so far I'm running into an issue when it comes to the server receiving the data; it only seems to process it after the client connection has been terminated. This points to me that the data is getting sent, but the server is keeping its inputstream open and waiting for more data. Would anyone know how I might go about solving this? The current code (or at least the relevant parts) is as follows: iPhone: Person *person = [[[[Person builder] setId:1] setName:@"Bob"] build]; RequestWrapper *request = [[[RequestWrapper builder] setPerson:person] build]; NSData *data = [request data]; AsyncSocket *socket = [[AsyncSocket alloc] initWithDelegate:self]; if (![socket connectToHost:@"192.168.0.6" onPort:6666 error:nil]){ [self updateLabel:@"Problem connecting to socket!"]; } else { [self updateLabel:@"Sending data to server..."]; [socket writeData:data withTimeout:-1 tag:0]; [self updateLabel:@"Data sent, disconnecting"]; //[socket disconnect]; } Java: try { RequestWrapper wrapper = RequestWrapper.parseFrom(socket.getInputStream()); Person person = wrapper.getPerson(); if (person != null) { System.out.println("Persons name is " + person.getName()); socket.close(); } On running this, it seems to hang on the line where the RequestWrapper is processing the inputStream. I did try replacing the socket writedata method with [request writeToOutputStream:[socket getCFWriteStream]]; Which I thought might work, however I get an error claiming that the "Protocol message contained an invalid tag (zero)". I'm fairly certain that it doesn't contain an invalid tag as the message works when sending it via the writedata method. Any help on the matter would be greatly appreciated! Cheers! Dan (EDIT: I should mention, I am using the metasyntactic gpb code; and the cocoaasyncsocket implementation)

  • Map tiling - What kind of projection?

    - by ikky
    Hi. I've taken a large image and divided it in to square tiles (256x256). It is made for google maps also, so the whole image is divided into z_x_y.png (Depending on zoom level). z=0 = 1x1 tile z=1 = 2x2 tilesthe z=2 = 4x4 tiles My imageMap is "flat" and is not based on a sphere like the worldmap. I'm gonna use this map on a windows mobile app (which has no google API), and all the "points of interests" is inserted into a database by longitude and latitude. And since i have to make this for the windows mobile, i just have XY coordinate system. Is it enough to just use this: MAP_WIDTH = 256*TILES_W; MAP_HEIGHT = 256*TILES_H; function convert(int lat, int lon) { int y = (int)((-1 * lat) + 90) * (MAP_HEIGHT / 180); int x = (int)(lon + 180) * (MAP_WIDTH / 360); ImagePoint p = new ImagePoint(x,y); // An object which holds the coordinates return p; } Or do i need a projection technique? Thanks in advance. Please ask, if something is unclear.

But I am getting an access control exception when my code is tyring to access that xsd. java.security.AccessControlException: access denied (java.io.FilePermission \WEB-INF\ApplicationResponse.xsd read) at java.security.AccessControlContext.checkPermission(AccessControlContext.java:264) at java.security.AccessController.checkPermission(AccessController.java:427) at java.lang.SecurityManager.checkPermission(SecurityManager.java:532) at com.google.appengine.tools.development.DevAppServerFactory$CustomSecurityManager.checkPermission(DevAppServerFactory.java:166) at java.lang.SecurityManager.checkRead(SecurityManager.java:871) at java.io.FileInputStream.(FileInputStream.java:100) at com.sun.org.apache.xerces.internal.impl.xs.XMLSchemaLoader.xsdToXMLInputSource(XMLSchemaLoader.java:830) at com.sun.org.apache.xerces.internal.impl.xs.XMLSchemaLoader.processJAXPSchemaSource(XMLSchemaLoader.java:708) at com.sun.org.apache.xerces.internal.impl.xs.XMLSchemaLoader.loadSchema(XMLSchemaLoader.java:554) at com.sun.org.apache.xerces.internal.impl.xs.XMLSchemaValidator.findSchemaGrammar(XMLSchemaValidator.java:2459) at com.sun.org.apache.xerces.internal.impl.xs.XMLSchemaValidator.handleStartElement(XMLSchemaValidator.java:1807) at com.sun.org.apache.xerces.internal.impl.xs.XMLSchemaValidator.startElement(XMLSchemaValidator.java:705) at com.sun.org.apache.xerces.internal.impl.XMLNSDocumentScannerImpl.scanStartElement(XMLNSDocumentScannerImpl.java:330) at com.sun.org.apache.xerces.internal.impl.XMLNSDocumentScannerImpl$NSContentDispatcher.scanRootElementHook(XMLNSDocumentScannerImpl.java:779) at com.sun.org.apache.xerces.internal.impl.XMLDocumentFragmentScannerImpl$FragmentContentDispatcher.dispatch(XMLDocumentFragmentScannerImpl.java:1794) at com.sun.org.apache.xerces.internal.impl.XMLDocumentFragmentScannerImpl.scanDocument(XMLDocumentFragmentScannerImpl.java:368) at com.sun.org.apache.xerces.internal.parsers.XML11Configuration.parse(XML11Configuration.java:834) at com.sun.org.apache.xerces.internal.parsers.XML11Configuration.parse(XML11Configuration.java:764) at com.sun.org.apache.xerces.internal.parsers.XMLParser.parse(XMLParser.java:148) at com.sun.org.apache.xerces.internal.parsers.AbstractSAXParser.parse(AbstractSAXParser.java:1242) at sax.SAXLocalNameCount.parse(SAXLocalNameCount.java:220) at com.sms2mint.InterfaceServlet.doGet(InterfaceServlet.java:54) Please let me know how to debug this? I have tried to place the xsd in classes, webcontent, /WEB-INF but didn't help. Also declared this as a resource file in appengine-web.xml also but no avail.

  • z-index has no effect in IE7 with Google Map and Navigation Sub-Menus

    - by bhamrick
    I feel like the problem is extremely apparent. I'm working on an issue with a client's site, which actually happens on several of my clients' sites but this one is the most apparent. IE7 Is refusing to obey z-index rules. I've played around with differing values, particularly on the divs #mapWrapper and #map. Take a look here: http://thepaysongroup.com/wp-content/plugins/hq_idx/searchlistings.php I've done dozens of web searches and I can't find anything that resolves this issue. I also ready through Aleksandar Vacic's article on IE6/7 z-index discrepancies, but still nothing. Any assistance would be much appreciated, I'm tearing my hair out on this one.

  • Creating a dynamic (video) Overlay on Google Maps on Android 2.1

    - by Soumya
    I'm trying to create a map overlay for displaying a video stream (MJPEG) on top of a Mapview. Currently I've a standalone activity that creates a data thread for fetching MJPEG video frames. I'm using a handler to send a frame (as a Bitmap) from the data thread to the main activity which then updates the UI. I'm not sure how I can implement "refresh" for updating my "overlayed" video stream. EDIT: What I mean by "refresh" is - how can I update the video portion (not the mapview) of my UI whenever I get a new video frame. I plan to paint the video frame (bitmap) in the "draw method" of my implementation of the Overlay subclass. But the "draw" method is not invoked by me directly. Thanks.

  • Unity3D, Torque3D, Google O3D, WebGl....which to choose?

    - by gpwjg
    for development of interactive 3d web applications, which engine is recommended? I am aware that WebGL has been anounced to become standarized for all browsers in the near future (1~2 years). I am afraid that by investing time into a proprietary game engine such as Unity, torque would be not great once plugin-less open source 3d engines appear (webgl & 3D javascript). Is this a stupid thing to worry about ? Should I begin with Unity3D (it's demo's and tools were mind blowing).

  • Java Google App Engine inconsistent data lose after restarting dev server

    - by user259349
    Hello everyone, I am using Java GAE. So far, i'm just scafolding my data objects and i'm seeing an interesting issue. The records that i am playing around with are getting updated properly as long as my dev server is running up. The second that the my dev server gets restarted, i lose all of my changes. That would be not alarming if i lost all of my records, but, there was a point of time where my data persisted through the server restart. I'm worried that i would lose production data if i launched without fixing this potential bugs? ANy idea on wher ei should look?
