• Does Google crawl AJAX content?

  - by Doug

  On the home page of my site I use JQuery's ajax function to pull down a list of recent activity of users. The recent activity is displayed on the page, and each line of the recent activity includes a link to the user profile of the user who did the activity. Will Google actually make the ajax call to pull down this info and use it in calculating page relevancy / link juice flow? I'm hoping that it does not because the user profile pages are not very Google index worthy, and I don't want all those links to the User profile pages diluting my home page's link juice flow away from other more important links.

• Creating folders using PHP in google docs

  - by Isaac

  Hi, Currently I am working on a project integrating google docs to my application using php. However, there is only version1 for the php and I am not well-versed with REST web service. And I am required to create folder using the api. I wonder any people manage/know how to do it? Below is the protocol for the creation of the folder. If anyone know how to do it, I would be glad if you can assist me. Thank you in advance. POST /feeds/default/private/full HTTP/1.1 Host: docs.google.com GData-Version: 3.0 Authorization: Content-Length: 245 Content-Type: application/atom+xml Example Folder

• Randomly Losing Session Variables Only In Google Chrome & URL Rewriting

  - by Toby

  Using Google Chrome, I'm seemingly losing/corrupting session data when navigating between pages (PHP 5.0.4, Apache 2.0.54). The website works perfectly fine in IE7/8, Firefox, Safari & Opera. The issue is only with Google Chrome. I narrowed down the problem. I'm using search friendly URL's, and hiding my front controller (index.php) via a .htaccess file. So the URL looks like: www.domain.com/blah/blah/ Here's the .htaccess file contents: Options +FollowSymlinks RewriteEngine on #allow cool urls RewriteCond %{REQUEST_FILENAME} !-f RewriteCond %{REQUEST_FILENAME} !-d RewriteRule ^(.*) index.php [L] #allow to have Url without index.php If I remove the .htaccess file, and expose the front controller in the URL: www.domain.com/index.php/blah/blah/, Chrome works perfectly fine. Any thoughts ideas? I'm thinking it's some kind of problem with how Chrome identifies what cookie to use and send to the server? This happens in Chrome 4 & 5. Thanks!

• How to build a private "Google Apps Marketplace" apps for gmail intergration like Rapportive does

  - by Hans Klock

  Google Apps Marketplace (http://www.google.com/enterprise/marketplace/) has enabled contextual gadgets so I could integrate my functionality in gmail. I would like to do so but I don't want to publish the app. Is this possible? (http://developer.googleapps.com/marketplace/getting-started tells me I have to become a vendor.) If I can do so I can't find any example code how to integrate in gmail, e.x. access a message, add a button, ... BTW: Greasemonkey is NOT an option.

• Android Google Play Services Error whilst Connecting

  - by TastyLemons

  I am attempting to implement the Google Play Services into my Game to add a Leaderboard. However, whenever I try to connect, I get the following error message: I have correctly imported google-play-services_lib into my project, and AdMob is working perfectly. This error message comes up after it tries to login. The account with which I am logging in, is authorized as a Test account so that shouldn't be the issue. There are no error messages in the LogCat window either. All I got was that Error Message from the image. Project hierarchy : I am assuming that simply Extending the Activity from BaseGameActivity should handle everything for me right?

• Regex help with Google Page Monitor extension

  - by bibliwho

  I'm trying to monitor a small section of a web page for changes using the the Google Page Monitor extension -- https://chrome.google.com/extensions/detail/pemhgklkefakciniebenbfclihhmmfcd Under advanced settings I can use either Regex or Selectors to accomplish this, but need help with this. In the following html, I'd like to monitor the following for changes in either the URL in line 4 or the text in line 5.

• Chrome's new window disappear from desktop

  - by faulty

  I'm having this problem with Chrome on a Windows 7 x86 machine. I'm using Chrome for a locally hosted intranet web app. In the web app, there's frequent use of new window which popup, which works like a dialog box for the app. The problem started since yesterday. All the new windows doesn't appear on top and no where to be found on the desktop. But it does appear on the taskbar. Clicking the button on the taskbar doesn't bring up the window as well. I've also tried Alt+Space, then Move, it doesn't work. I only found 2 way to bring it up, Maximize or Show as tab. What could have caused this and how should I fix it? Thanks EDIT: I've configure to not group taskbar buttons. EDIT: I've just gone through the javascript of the button, it call window.open to display the popup. I can see the popup flicker and disappear. If I step through the code, the popup will display properly, sometime. Also, if I click the button twice, it will also display the popup, but at a much smaller size, less than 100x100

• I added some options to stop spam with Postfix, but now won't send email to remote domains

  - by willdanceforfun

  I had a working Postfix server, but added a few lines to my main.cf in a hope to block some common spam. Those lines I added were: smtpd_helo_required = yes smtpd_recipient_restrictions = reject_invalid_hostname, reject_unknown_recipient_domain, reject_unauth_pipelining, permit_mynetworks, permit_sasl_authenticated, reject_unauth_destination, reject_rbl_client multi.uribl.com, reject_rbl_client dsn.rfc-ignorant.org, reject_rbl_client dul.dnsbl.sorbs.net, reject_rbl_client list.dsbl.org, reject_rbl_client sbl-xbl.spamhaus.org, reject_rbl_client bl.spamcop.net, reject_rbl_client dnsbl.sorbs.net, reject_rbl_client cbl.abuseat.org, reject_rbl_client ix.dnsbl.manitu.net, reject_rbl_client combined.rbl.msrbl.net, reject_rbl_client rabl.nuclearelephant.com, permit It appears my postfix is now receiving normal emails fine, and blocking spam emails. But when I now try to use this server myself to send to a remote domain (an email not on my server) I get bounced, with maillog saying something like this: Nov 12 06:19:36 srv postfix/smtpd[11756]: NOQUEUE: reject: RCPT from unknown[xx.xx.x.xxx]: 450 4.1.2 <[email protected]>: Recipient address rejected: Domain not found; from=<[email protected]> to=<[email protected]> proto=ESMTP helo=<[192.168.1.100]> Is that saying 'domain not found' for gmail.com?

How did the hacker even manage to send a GET request to my server such that "http://www.google.com" shows up in the log while my server is simply an API that works on relative URLs such as "/api/login". And, while I looked up the OPTIONS, TRACE and PROPFIND HTTP requests that my server has logged it would be great if someone could explain what exactly was the hacker trying to achieve by using these verbs? Also what in the world does "[90m [32m [90m1ms - 240b[0m" mean? The "ms" makes sense, probably milliseconds for the request, rest I am unable to understand. Thank you!

• Contact-app like scrollinglist on android

  I'm writing my first android app (I'm a noob at android, but decent at java). The first screen of the app consists of a huge list (about 1.5K items) of Manga-objects. The code I use is as following: main.xml: <?xml version="1.0" encoding="utf-8"?> <LinearLayout android:id="@+id/LinearLayout01" android:layout_width="fill_parent" android:layout_height="fill_parent" xmlns:android="http://schemas.android.com/apk/res/android"> <ListView android:layout_height="fill_parent" android:layout_width="fill_parent" android:id="@+id/android:list"></ListView> <TextView android:layout_height="fill_parent" android:layout_width="fill_parent" android:text="@string/list_no_items" android:id="@+id/android:empty"></TextView> </LinearLayout> row.xml: <LinearLayout android:id="@+id/LinearLayout01" android:layout_width="fill_parent" android:layout_height="?android:attr/listPreferredItemHeight" android:padding="6dip" xmlns:android="http://schemas.android.com/apk/res/android"> <ImageView android:id="@+id/icon" android:layout_width="wrap_content" android:layout_height="fill_parent" android:layout_marginRight="6dip" android:src="@drawable/icon" /> <LinearLayout android:orientation="vertical" android:layout_width="0dip" android:layout_weight="1" android:layout_height="fill_parent"> <TextView android:id="@+id/toptext" android:layout_width="fill_parent" android:layout_height="0dip" android:layout_weight="1" android:gravity="center_vertical" /> <TextView android:layout_width="fill_parent" android:layout_height="0dip" android:layout_weight="1" android:id="@+id/bottomtext" android:singleLine="true" android:ellipsize="marquee" /> </LinearLayout> </LinearLayout> Then I have a adapter which basically takes a Manga-object and puts it's name in the rows toptext, and it's latest updated date in the bottomtext. However, (this might be caused by the virtualization of the unit though), the result is really slow. Scrolling the list takes forever and you can only scroll small peaces of the time. How can I make the list work like the one in the contacts-app? So that when you start scrolling a handle pops out at the right side of the screen, and when you drag it letters shows up as of how far you've scrolled (the list is sorted alphabetically), and also, is there a way I could improve the performance of the list?

• Differing paths for lua script and app

  - by Person

  My problem is that I'm having trouble specifying paths for Lua to look in. For example, in my script I have a require("someScript") line that works perfectly (it is able to use functions from someScript when the script is run standalone. However, when I run my app, the script fails. I believe this is because Lua is looking in a location relative to the application rather than relative to the script. Hardcoding the entire path down to the drive isn't an option since people can download the game wherever they like so the highest I can go is the root folder for the game. We have XML files to load in information on objects. In them, when we specify the script the object uses, we only have to do something like Content\Core\Scripts\someScript.lua where Content is in the same directory as Debug and the app is located inside Debug. If I try putting that (the Content\Core...) in Lua's package.path I get errors when I try to run the script standalone. I'm really stuck, and am not sure how to solve this. Any help is appreciated. Thanks. P.S. When I print out the default package.path in the app I see syntax like ;.\?.lua in a sequence like... ;.\?.lua;c:...(long file path)\Debug\?.lua; I assume the ; means the end of the path, but I have no idea what the .\?.lua means. Any Lua file in the directory?

• Rails App hangs after few requests

  - by Paddy

  I have Bitnami Rails stack installed on my Mac. To better explain my problem i created a simple scaffold based rails app with mysql as the backend. I can get to perform simple POST and GET requests for a while and after a few requests the app just hangs indefinitely. No exception caught or anything worthwhile in the development log to report this strange behavior. This is the last bit from the development log before the app froze: Processing WritedatasController#index (for 127.0.0.1 at 2010-03-30 20:38:51) [GET] [4;36;1mWritedata Load (0.7ms) [0m [0;1mSELECT * FROM `writedatas` [0m Rendering template within layouts/application Rendering writedatas/index [4;35;1mWritedata Columns (2.9ms) [0m [0mSHOW FIELDS FROM `writedatas` [0m Completed in 99ms (View: 88, DB: 4) | 200 OK [http://localhost/writedatas] [4;36;1mSQL (0.2ms) [0m [0;1mSET NAMES 'utf8' [0m [4;35;1mSQL (0.1ms) [0m [0mSET SQL_AUTO_IS_NULL=0 [0m Processing WritedatasController#new (for 127.0.0.1 at 2010-03-30 20:38:52) [GET] [4;36;1mWritedata Columns (2.0ms) [0m [0;1mSHOW FIELDS FROM `writedatas` [0m Rendering template within layouts/application Rendering writedatas/new Rendered writedatas/_form (5.9ms) Completed in 34ms (View: 25, DB: 2) | 200 OK [http://localhost/writedatas/new] [4;36;1mSQL (0.4ms) [0m [0;1mSET NAMES 'utf8' [0m [4;35;1mSQL (0.1ms) [0m [0mSET SQL_AUTO_IS_NULL=0 [0m Processing WritedatasController#index (for 127.0.0.1 at 2010-03-30 20:39:17) [GET] [4;36;1mWritedata Load (0.7ms) [0m [0;1mSELECT * FROM `writedatas` [0m Rendering template within layouts/application Rendering writedatas/index [4;35;1mWritedata Columns (2.6ms) [0m [0mSHOW FIELDS FROM `writedatas` [0m Completed in 101ms (View: 90, DB: 4) | 200 OK [http://localhost/writedatas] It just hung at this point. And after this happens i have to restart the server, for it to hang again after few requests. This is the weirdest problem i have faced and i am truly stumped.

• App crashes only after second execution only in Release configuration

  - by denbec

  Hey all, i know this is probably not an easy question to answer, as it's hard to describe on my hand. I have an app that runs without problems on the device in Debug Configuration (also multiple times). Once I put it into Release Configuration (which I need before publishing?), the app starts without problems and I can proceed to the next page, where I show an core-plot graph. BUT only if I run it from xcode. As soon as I end the App and start it again, it opens without problems, but on the next page, it crashes. Now I don't have anything to debug other than the crash report: Exception Type: EXC_BAD_ACCESS (SIGSEGV) Exception Codes: KERN_INVALID_ADDRESS at 0xcf10000a Crashed Thread: 0 Thread 0 Crashed: 0 libobjc.A.dylib 0x000026f2 objc_msgSend + 14 1 StandbyCheck 0x0001fbea -[CPXYTheme newGraph] (CPXYTheme.m:36) 2 StandbyCheck 0x00007c06 -[SCGraphCell initWithStyle:reuseIdentifier:] (SCGraphCell.m:28) 3 StandbyCheck 0x00076b4a -[TTTableViewDataSource tableView:cellForRowAtIndexPath:] (TTTableViewDataSource.m:128) 4 UIKit 0x0007797a -[UITableView(UITableViewInternal) _createPreparedCellForGlobalRow:withIndexPath:] + 514 5 UIKit 0x000776b0 -[UITableView(UITableViewInternal) _createPreparedCellForGlobalRow:] + 28 6 UIKit 0x00037e78 -[UITableView(_UITableViewPrivate) _updateVisibleCellsNow] + 940 7 UIKit 0x000367d4 -[UITableView layoutSubviews] + 176 8 StandbyCheck 0x000734b8 -[TTTableView layoutSubviews] (TTTableView.m:226) [...] Now, can someone point in any direction? What are the differences in Debug/Release Modes? How could I possibly debug this failure? I've been searching for hours now, please help me :( Thanks, Dennis

• NSFILEMANAGER CRASHING IN APP DELEGATE

  - by theiphoneguy

  I have this code in a method called from applicationDidFinishLaunching. It works in the simulator, but crashes on the iPhone. There are about 1,600 2KB mp3 files being copied in this operation. If I try to instantiate the app multiple times, it will eventually copy more each time until the app eventually will start without crashing. I am releasing everything I allocate. I have about 20GB disk space free on the iPhone. If I progressively comment out code and run it on the iPhone, the copyItemAtPath seems to be the suspect. (void)createCopyOfAudioFiles:(BOOL)force { @try { NSError *error; NSString *component; NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES); NSString *documentsDirectory = [paths objectAtIndex:0]; NSFileManager *fileManager = [[NSFileManager alloc] init]; NSEnumerator *enumerator = [[[NSBundle mainBundle]pathsForResourcesOfType:@"mp3" inDirectory:nil] objectEnumerator]; while ((component = [enumerator nextObject]) != nil) { NSArray *temp = [component componentsSeparatedByString:@".app/"]; NSString *file = [NSString stringWithFormat:@"%@", [temp objectAtIndex:1]]; NSString *writableAudioPath = [documentsDirectory stringByAppendingPathComponent:file]; BOOL success = [fileManager fileExistsAtPath:writableAudioPath]; if (success &amp;&amp; !force) { continue; } else if (success &amp;&amp; force) { success = [fileManager removeItemAtPath:writableAudioPath error:&amp;error]; } success = [fileManager copyItemAtPath:component toPath:writableAudioPath error:&amp;error]; if (!success) { @throw [NSException exceptionWithName:[error localizedDescription] reason:[error localizedFailureReason] userInfo:nil]; } } [fileManager release]; } @catch (NSException *exception) { NSLog(@"%@", exception); @throw [NSException exceptionWithName:exception.name reason:exception.reason userInfo:nil]; } @finally { } }

• iPhone SDK 3.2 Universal App issue with .xib files

  - by Wesley

  Hello! So I am finding this process of universalizing my iPhone app to be a big headache! Am I alone in this? I sure hope not. Anyway, my question is regarding the .xib files for my universal application. I had my iPhone OS 3.1 running app all ready to make the universal switch. I went up to Project/Upgrade Current Target for iPad/Universal Application and it supposedly made my app have all the necessary iPad settings... So when I went to test it in 3.2 SDk, the screen was big, meaning the toolbar was sized correctly for the iPad, but the image that was being displayed was for the OS 3.1, meaning it was way small. So I then went to the iPad Source folder, changed the name of my MainViewController.xib file to MainViewController-iPad.xib, and inserted the bigger image I had prepared for the iPad, and it still didn't work correctly. Then, I went into my MainViewController.m file and changed the nib reference from MainViewController to MainViewController-iPad, and it worked! My only concern is that being that I had to "hard-code" it in, or force it to read from my -iPad file, is that going to present issues for the OS3.1 version? I can't go back and test the 3.1 version now for some reason, the option was removed from the Active SDK menu... If there is anyone out there that has experienced this, or has insight into what I am doing wrong, your help would be greatly appreciated. Thank you!

• Keyboard hook return different symbols from card reader depends whther my app in focus or not

  - by user363868

  I code WinForm application where one of the input is magnetic stripe card reader (CR). I am using code George Mamaladze's article Processing Global Mouse and Keyboard Hooks in C# on codeproject.com to listen keyboard (USB card reader acts same way as keyboard) and I have weird situation. One card reader CR1 (Unitech MS240-2UG) produces keystroke which I intercept on KeyPress event analyze that I intercept certain patter like %ABCD-6EFJHI? and trigger some logic. Analysis required because user can type something else into application or in another application meanwhile my app is open When I use another card reader CR2 (IdTech IDBM-334133) keystroke intercepted by hook started from number 5 instead of % (It is actually same key on keyboard). Since it is starting sentinel it is very important for me to have ability recognize input from card reader. Moreover if my app running in background and I have focus on Notepad when I swipe card string %ABCD-6EFJHI? appears in Notepad and same way, with proper starting character) intercepted by keyboard hook. If swiped when focus on Form it is 5ABCD-6EFJHI? User who tried app with another card reader has same result as me with CR2. Only CR1 works for me as expected I was looking into Device manager of Windows and both devices use same HID driver supplied by MS. I checked devices though respective software from CR makers and starting and ending sentinels set to % and ? respective on both. I would appreciate and ideas and thoughts as I hit the wall myself Thank you

• Prerequisites for Account management via an IPhone App?

  - by Icky

  Hello. I have been reading a couple of threads for this topic on this site. I want to create an App, which communicates with a server and has the following features: the User can create/manage an account on the server the App communicates with the server via a secure connection the User is updated about important news through messages From what I understood so far, I need to take care of the following: establish a secure connection with the server send account information(user data, password) to the server and authenticate the client side management and encryption of account data/information is handled by the server, so the App only sends data, the server stores/encrypts (no need for me to take care of anything) So far, I think, I have covered the most important features. I have read, that NSURLConnection can be used, to send the authentication data. But how is further communication ensured? And how is the encryption managed? Are there any useful tutorials on this, because this is the first time I delve into this topic, and any guidance is greatly appreciated! Also, if I have missed anything important (e.g. with managing accounts) please tell me.

• 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.

• Trouble creating a Java policy server for a simple Flash app

  - by simonwulf

  I'm trying to create a simple Flash chat application for educational purposes, but I'm stuck trying to send a policy file from my Java server to the Flash app (after several hours of googling with little luck). The policy file request reaches the server that sends a harcoded policy xml back to the app, but the Flash app doesn't seem to react to it at all until it gives me a security sandbox error. I'm loading the policy file using the following code in the client: Security.loadPolicyFile("xmlsocket://myhostname:" + PORT); The server recognizes the request as "<policy-file-request/" and responds by sending the following xml string to the client: public static final String POLICY_XML = "<?xml version=\"1.0\"?>" + "<cross-domain-policy>" + "<allow-access-from domain=\"*\" to-ports=\"*\" />" + "</cross-domain-policy>"; The code used to send it looks like this: try { _dataOut.write(PolicyServer.POLICY_XML + (char)0x00); _dataOut.flush(); System.out.println("Policy sent to client: " + PolicyServer.POLICY_XML); } catch (Exception e) { trace(e); } Did I mess something up with the xml or is there something else I might have overlooked?

• Using GDataXMLDocument in iPad app

  - by INs

  I'm trying to use GDataXML library in my ipad application. I followed by instructions: Download the gdata-objective-c client library. Unzip the file, navigate to Source\XMLSupport, and drag the two files GDataXMLNode.h and GDataXMLNode.m into your project In XCode, click Project\Edit Project Settings and make sure “All Configurations” are checked. Find the Search Paths\Header Search Paths setting and add /usr/include/libxml2 to the list. Finally, find the Linking\Other Linker Flags section and add -lxml2 to the list. If in code i add #import "GDataXMLNode.h", all is fine. But when i try to use GDataXMLDocument class in my app GDataXMLDocument *doc = [[GDataXMLDocument alloc] initWithData:xmlData options:0 error:nil]; I received the following message: Ld build/Debug-iphonesimulator/DemoApp.app/DemoApp normal i386 cd /Users/svp/Projects/DemoApp setenv MACOSX_DEPLOYMENT_TARGET 10.6 setenv PATH "/Developer/Platforms/iPhoneSimulator.platform/Developer/usr/bin:/Developer/usr/bin:/usr/bin:/bin:/usr/sbin:/sbin" /Developer/Platforms/iPhoneSimulator.platform/Developer/usr/bin/gcc-4.2 -arch i386 -isysroot /Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator4.2.sdk -L/Users/svp/Projects/DemoApp/build/Debug-iphonesimulator -F/Users/svp/Projects/DemoApp/build/Debug-iphonesimulator -filelist /Users/svp/Projects/DemoApp/build/DemoApp.build/Debug-iphonesimulator/DemoApp.build/Objects-normal/i386/DemoApp.LinkFileList -mmacosx-version-min=10.6 -Xlinker -objc_abi_version -Xlinker 2 -framework Foundation -framework UIKit -framework CoreGraphics -framework MapKit -framework QuartzCore -lxml2.2 -o /Users/svp/Projects/DemoApp/build/Debug-iphonesimulator/DemoApp.app/DemoApp Undefined symbols: "_OBJC_CLASS_$_GDataXMLDocument", referenced from: objc-class-ref-to-GDataXMLDocument in TwitterService.o ld: symbol(s) not found collect2: ld returned 1 exit status Any thoughts?

• OpenPeak Flash app XMLSocket Security Problem

  - by Kira

  We're trying to create an app for OpenPeak. The Flash app will act as a client to a Java server on another computer on another domain. The Flash app client connects via XMLSocket. The Java Server uses ServerSocket to receive a request and send back a message. In order to trust the server, the Flash client needs a socket master policy file to tell it that the server comes from a trustworthy domain. According to an article on Adobe, when a connection has succeeded, the Flash client automatically requests the cross-domain policy or socket master policy file on port 843. Still, even when we implement it according to the tutorials and recommendations we have read, the Flash client continues to throw the following security error: SecurityErrorEvent type="securityError" bubbles=false cancelable=false eventPhase=2 text="Error #2048" We've tried logging the policy file request during testing to see if there was any call made to port 843. There was not. Interestingly, even without a policy file, the Flash client still manages to send the first data message to the server successfully. It's just when the server tries to send back a reply that the entire thing hangs for about 10 seconds before the security error above is displayed. Any ideas / suggestions?
