• onServiceConnected never called after bindService method

  - by Tobia Loschiavo

  Hi, I have a particular situation: a service started by a broadcast receiver starts an activity. I want to make it possible for this activity to communicate back to the service. I have chosen to use AIDL to make it possible. Everything seems works good except for bindService() method called in onCreate() of the activity. bindService(), in fact, throws a null pointer exception because onServiceConnected() is never called while onBind() method of the service is. Anyway bindService() returns true. The service is obviously active because it starts the activity. I know that calling an activity from a service could sound strange, but unfortunately this is the only way to have speech recognition in a service. Thanks in advance

• Is this a good implementation of DefaultHttpClient and ThreadSafeClientConnManager in Android?

  - by johnrock

  In my Android app I am sharing one httpclient for all activities/threads. All requests are made by callling getHttpClient().execute(httpget) or getHttpClient().execute(httppost). Is this implementation complete/correct and safe for multiple threads? Is there anything else missing i.e. Do I have to worry about releasing connections at all? private static HttpClient httpclient ; public static HttpClient getHttpClient() { if(httpclient == null){ return getHttpClientNew(); } else{ return httpclient; } } public static synchronized HttpClient getHttpClientNew() { HttpParams params = new BasicHttpParams(); ConnManagerParams.setMaxTotalConnections(params, 100); HttpProtocolParams.setVersion(params, HttpVersion.HTTP_1_1); HttpProtocolParams.setContentCharset(params, "UTF_8"); HttpProtocolParams.setUseExpectContinue(params, false); HttpConnectionParams.setConnectionTimeout(params, 10000); HttpConnectionParams.setSoTimeout(params, 10000); SchemeRegistry schemeRegistry = new SchemeRegistry(); schemeRegistry.register(new Scheme("http", PlainSocketFactory.getSocketFactory(), 80)); ClientConnectionManager cm = new ThreadSafeClientConnManager(params, schemeRegistry); httpclient = new DefaultHttpClient(cm, params); return httpclient; } This is an example of how the httpclient is used: private void update() { HttpGet httpget = new HttpGet(URL); httpget.setHeader(USER_AGENT, userAgent); httpget.setHeader(CONTENT_TYPE, MGUtils.APP_XML); HttpResponse response; try { response = getHttpClient().execute(httpget); HttpEntity entity = response.getEntity(); if (entity != null) { // parse stuff } } catch (Exception e) { } }

• App cannot start at all in Android 2.2 (Froyo)

• How should I distribute a pre-built perl module, and what version of perl do I build for?

  - by Mike Ellery

  This is probably a multi-part question. Background: we have a native (c++) library that is part of our application and we have managed to use SWIG to generate a perl wrapper for this library. We'd now like to distribute this perl module as part of our application. My first question - how should I distribute this module? Is there a standard way to package pre-built perl modules? I know there is ppm for the ActiveState distro, but I also need to distribute this for linux systems. I'm not even sure what files are required to distribute, but I'm guessing it's the pm and so files, at a minimum. My next question - it looks like I might need to build my module project for each version of perl that I want to support. How do I know which perl versions I should build for? Are there any standard guidelines... or better yet, a way to build a package that will work with multiple versions of perl? Sorry if my questions make no sense - I'm fairly new to the compiled module aspects of perl. CLARIFICATION: the underlying compiled source is proprietary (closed source), so I can't just ship source code and the appropriate make artifacts for the package. Wish I could, but it's not going to happen in this case. Thus, I need a sane scheme for packaging prebuilt binary files for my module.

• How to stream a shoutcast radio broadcast in Flash (Shoutcast Flash Player)

  - by Jourdan

  I've been looking for a solution to this for years, but nothing is conclusively documented. There are many Shoutcast Flash players out there (e.g. radio.de) so I know it's possible. However, most of my research leads to this: s = new Sound(); s.loadSound ("url.of.shoutcaststream:8003",true); Which works for me in FireFox but not in IE. I don't want to buy a component, I want to know how those components do it so that I can build my own custom player.

• Gzip http compression problem on iis7

  - by wpfwannabe

  My web hosting provider is running IIS7 and I am having loads of trouble to get gzip compression to work properly. Host admins say compression is installed. I can confirm compression using some online checking services but not with others. PageSpeed Firefox add-on also says the site is uncompressed. I am personally sitting behind a Squid proxy but web.config settings should take care of proxy issue. Below is the relevant web.config snippet. Most of it is borrowed from various sites. Any thoughts? <urlCompression doDynamicCompression="true" dynamicCompressionBeforeCache="true" doStaticCompression="true" /> <httpCompression cacheControlHeader="max-age=86400" noCompressionForHttp10="False" noCompressionForProxies="False" sendCacheHeaders="True" dynamicCompressionEnableCpuUsage="89" dynamicCompressionDisableCpuUsage="90" minFileSizeForComp="1" noCompressionForRange="False"> <scheme name="gzip" dll="%Windir%\system32\inetsrv\gzip.dll" /> <dynamicTypes> <add mimeType="text/*" enabled="true" /> <add mimeType="message/*" enabled="true" /> <add mimeType="application/javascript" enabled="true" /> <add mimeType="*/*" enabled="false" /> </dynamicTypes> <staticTypes> <add mimeType="text/*" enabled="true" /> <add mimeType="message/*" enabled="true" /> <add mimeType="application/javascript" enabled="true" /> <add mimeType="*/*" enabled="false" /> </staticTypes> </httpCompression>

• UISearchBar and UINavigationItem

  - by tbehunin

  I can't seem to get a UISearchBar to position itself from the far left to the far right in the navigation bar. In the -(void)viewDidLoad method, I have the following code: `UISearchBar *sb = [[UISearchBar alloc] initWithFrame:self.tableView.tableHeaderView.frame]; sb.delegate = self; self.navigationItem.titleView = sb; [sb sizeToFit]; [sb release];` When you build and run, it looks just fine at first glance. However, looking more closely, you can tell there is a margin/space on the left. This wouldn't be a big deal in the grand scheme of things, but when I tap the search bar to start a search, I animate the cancel button into view. Because the search bar is positioned slightly to the right, the animation is jerky and the cancel button falls off the end like so: link text It seems as if the UINavigationItem is like a table with three cells, where there is a padding on the first and last which I can't remove - nor does there seem to be a way to 'merge' it all together and then place the search bar there. I know this look is possible, because the AppStore search has a search bar in the navigation bar and it goes all the way to the edges. Anyone know how to get the search bar to go all the way to the edges so my slide-in cancel button animation will work properly?

• How can I change the images on an ImageButton in Android when using a OnTouchListener?

  - by Cody

  I have the following code which creates an ImageButton and plays a sound when clicked: ImageButton SoundButton1 = (ImageButton)findViewById(R.id.sound1); SoundButton1.setImageResource(R.drawable.my_button); SoundButton1.setOnTouchListener(new OnTouchListener() { public boolean onTouch(View v, MotionEvent event) { if (event.getAction() == MotionEvent.ACTION_DOWN ) { mSoundManager.playSound(1); return true; } return false; } }); The problem is that I want the image on the ImageButton to change when you press it. The OnTouchListener appears to be overriding the touch and not allowing the images to change. As soon as I remove the OnTouchListener, the ImageButton swaps to a different image when pressed. Any ideas on how I can have the images change on the ImageButton while still using the OnTouchListener? Thank you very much!

• Plastic SCM vs. SVN

  - by jon37

  I'm currently researching new source control options for a team of 10 developers. We do .net development in Visual Studio 2008. We currently use VSS for source control. We are looking for a centralized source control solution(non-distributed), with a nice Visual Studio plugin. My manager has recommended Plastic SCM and I've always heard good things about Subversion. I'm trying to decide if we should adopt Subversion or Plastic SCM. There isn't much information out there about Plastic SCM (except what they've written) and I was wondering if it would be a good solution. They make it sound as if branching is much simpler. Subversion on the other hand has a robust, mature community, and it has been thoroughly field tested. What are the pros and cons to these tools? Also are there any other tools that you could suggest? Thanks

• WinDbg .for loop

• How to change VS2010 Add Reference box filter ?

  - by rook

  I'm getting used to the new IDE (it's vc# express), but the first contact is somewhat confusing. When I open the Add Reference dialog and switch to the .NET tab, a label above the assembly list states: "Filtered to:.NET Framework 4". And it's true - I can reference .NET 4.0 assemblies only plus things like XNA 3.1. However I can't see older assemblies i.e. Managed DirectX libs, which are obviously installed on my computer as there was no trouble with adding a ref to them in vc#08. What is this? How to change the filter? The label is read-only. These sound like dull guy's questions, but I'm out of lack of finding an answer and there is no intuitive solution. Thanks in advance.

• WCF, Metadata and BIGIP - Can I force the correct url for the WSDL items?

  - by Yossi Dahan

  We have a WCF service hosted on ServerA which is a server with no-direct Internet access and has a non-Internet routable IP address. The service is fronted by BIGIP which handles SSL encryption and decryption and forwards the unencrypted request to ServerA (at the moment it does NOT actually do any load balancing, but that is likely to be added in the future) on a specific port. What that means is that our clients would be calling the service through https://www.OurDomain.com/ServiceUrl and would get to our service on http://SeverA:85/ServiceUrl through the BIGIP device; When we browse to the WSDL published on https://www.OurDomain.com/ServiceUrl all the addresses contained in the WSDL are based on the http://SeverA:85/ServiceUrl base address We figured out that we could use the host headers setting to set the domain, but our problem is that while this would sort out the domain, we would still be using the wrong scheme – it would use http://www.OurDomain.com/ServiceUrl while we need it to be Https. Also – as we have other services (asmx based) hosted on that server we had some issues setting the host headers, and so we thought we could get away with creating another site on the server (using, say, port 82) and set the host header on that; now, on top of the http/https problem we have an issue as the WSDL contains the port number in all the urls, where BigIP works on port 443 (for the SSL) Is there a more flexible solution than implementing Host Headers? Ideally we need to retain flexibility and ease of supportability. Thanks for any help…

• Bug with audio reCaptcha in safari

  - by George Crawford

  Hi all, Can other Safari users please test http://recaptcha.net/learnmore.html for me, to see if the audio reCaptcha plays properly? On my machine, I can only hear the audio if I click the Download sound as MP3 link. I also don't get the spoken introduction at all. It works OK in Firefox and Chrome. I was alerted to this bug on my own development site, using the Zend Service for ReCaptcha. However, if it's broken on the official site, then I guess it's not a Zend bug. There don't seem to be any JavaScript errors. Any ideas?

• Using .NET's HttpWebRequest to download a multitude of files in a row

  - by Cornelius

  I have an application that needs to download several files in a row in succession (sometimes a few thousand). However, what ends up happening when several files need to be downloaded is I get an exception with an inner exception of type SocketException and the error code 10048 (WSAEADDRINUSE). I did some digging and basically it's because the server has run out of sockets (and they are all waiting for 240s or so before they become available again) - not coincidentally it starts happening around the 1024 file range. I would expect that the HttpWebRequest/ServicePointManager would be reusing my connection, but apparently it is not (and the files are https, so that may be part of it). I never saw this problem in the C++ code that this was ported from (but that doesn't mean it didn't ever happen - I'd be surprised if it was, though). I am properly closing the WebRequest object and the HttpWebRequest object has KeepAlive set to true by default. Next my intent is to fiddle around with ServicePointManager.SetTcpKeepAlive(). However, I can't see how more people haven't run into this problem. Has anyone else run into the problem, and if so, what did you do to get around it? Currently I have a retry scheme that detects this error and waits it out, but that doesn't seem like the right thing to do. Here's some basic code to verify what I'm doing (just in case I'm missing closing something): WebRequest webRequest = WebRequest.Create(uri); webRequest.Method = "GET"; webRequest.Credentials = new NetworkCredential(username, password); WebResponse webResponse = webRequest.GetResponse(); try { using(Stream stream = webResponse.GetResponseStream()) { // read the stream } } finally { webResponse.Close() }

• Is is possible to enable persistent cookies and disable session cookies?

  - by Sem Dendoncker

  Hello, We have an application that uses a persistent cookie to store the language of the user and a session cookie for authentication. Now our site starts with a number of tests such as: javascript, cookies, flash plugin, sound and popup and only if all tests succeed you can go to the logon page. After logging in you can see the application. Now one of our clients has a serieus problem, she passes all the tests but upon logging in she goes to the default page and get's redirected tot the logon page again. (form authentication). Now I was wondering how this is possible. It's allmost like a persistent cookie is enabled (otherweise she's not able to skip the language page) and a session cookie isn't. I hope this explains it a bit. Cheers, M.

• why do game engines prefer static libraries over dynamic link libraries

  - by numerical25

  I've been reading a few gaming books. And they always prefer to create the engine as a static library over dynamic link. I am new to c++ so I am not highly knowledge when it comes to static libraries and dynamic link libraries. All I know is static libraries increase the size of your program, where DLL link libraries are loaded as you need them within your program. [edit] I've played games where it almost seemed they used DLL's to load in sound, lighting, and what not all individually. as the level was loading up. cause you don't necessarily need that when your at the game menu.

• posting nutch data into a BASIC auth secured Solr instance

  - by mlathe

  Hi. I've secured a solr instance using BASIC auth, kind of how it is shown here: http://blog.comtaste.com/2009/02/securing_your_solr_server_on_t.html Now i'm trying to update my batch processes to push data into the authenticated instance.

Here are my question(s) Is this possible to do? ie push from nutch into a BASIC auth secured Solr instance? Is it possible to tell commons-httpclient about a credential without explicitly doing an _httpclient.getState().setCredentials(...)? Anyother ideas? One idea i had was to use an IPfiltering Valve for just the "update" Solr webservices. That would mean you could only make an update call from certain nodes. Thanks

• Is this so bad when using MySQL queries in PHP?

  - by alex

  I need to update a lot of rows, per a user request. It is a site with products. I could... Delete all old rows for that product, then loop through string building a new INSERT query. This however will lose all data if the INSERT fails. Perform an UPDATE through each loop. This loop currently iterates over 8 items, but in the future it may get up to 15. This many UPDATEs doesn't sound like too good an idea. Change DB Schema, and add an auto_increment Id to the rows. Then first do a SELECT, get all old rows ids in a variable, perform one INSERT, and then a DELETE WHERE IN SET. What is the usual practice here? Thanks

• Conflit between AVAudioRecorder and AVAudioPlayer

  - by John

  Hi, here is my problem : The code (FooController) : NSString *path = [[NSBundle mainBundle] pathForResource:@"mySound" ofType:@"m4v"]; soundEffect = [[AVAudioPlayer alloc] initWithContentsOfURL:[NSURL fileURLWithPath:path] error:NULL]; [soundEffect play]; // MicBlow micBlow = [[MicBlowController alloc]init]; And MicBlowController contains : NSURL *url = [NSURL fileURLWithPath:@"/dev/null"]; NSDictionary *settings = [NSDictionary dictionaryWithObjectsAndKeys: [NSNumber numberWithFloat: 44100.0], AVSampleRateKey, [NSNumber numberWithInt: kAudioFormatAppleLossless], AVFormatIDKey, [NSNumber numberWithInt: 1], AVNumberOfChannelsKey, [NSNumber numberWithInt: AVAudioQualityMax], AVEncoderAudioQualityKey, nil]; and [recorder updateMeters]; const double ALPHA = 0.05; double peakPowerForChannel = pow(10,(0.05*[recorder peakPowerForChannel:0])); lowPassResults = ALPHA * peakPowerForChannel + (1.0 - ALPHA) * lowPassResults; NSLog(@"Average input: %f Peak input %f Low pass results: %f",[recorder averagePowerForChannel:0],[recorder peakPowerForChannel:0],lowPassResults); If I play the background sound and try to get the peak from the mic I get this log : Average input: 0.000000 Peak input -120.000000 Low pass results: 0.000001 But if I comment all parts about AVAudioPlayer it works. I think there is a problem of channel. Thanks

• android: which view should I use for showing text and image?

  - by Yang

  My app shows a list of items, where each line is an item title with its image asides, the line reserves 70% of space for text and 30% for image. Imagine what iphone app store looks like. Which view/layout combo is recommended for this purpose? I googled and find this article: http://www.curious-creature.org/2009/02/22/android-layout-tricks-1/ Does this view sound good? <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="fill_parent" android:layout_height="?android:attr/listPreferredItemHeight" android:padding="6dip"> <ImageView android:id="@+id/icon" android:layout_width="wrap_content" android:layout_height="fill_parent" android:layout_alignParentTop="true" android:layout_alignParentBottom="true" android:layout_marginRight="6dip" android:src="@drawable/icon" /> <TextView android:id="@+id/secondLine" android:layout_width="fill_parent" android:layout_height="26dip" android:layout_toRightOf="@id/icon" android:layout_alignParentBottom="true" android:layout_alignParentRight="true" android:singleLine="true" android:ellipsize="marquee" android:text="Simple application that shows how to use RelativeLayout" /> <TextView android:layout_width="fill_parent" android:layout_height="wrap_content" android:layout_toRightOf="@id/icon" android:layout_alignParentRight="true" android:layout_alignParentTop="true" android:layout_above="@id/secondLine" android:layout_alignWithParentIfMissing="true" android:gravity="center_vertical" android:text="My Application" />

• Moving from WCF RIA Beta to RC: best practices?

  - by Duncan Bayne

  I have an existing WCF RIA project built on the Release Candidate; I'm now moving to the Release version & have discovered many changes. David Scruggs made the following comment on his (MSDN) blog: "If you’ve written anything in SIlverlight 4 RIA Services, you’ll need to rewrite it. There has been a lot of refactoring and namespace moves." Having made a brief attempt to compile the old solution with the new RIA framework I'm inclined to agree. My current plan is to: remove the Silverlight Business Application projects from the Solution rebuild the EF4 items from the database create a new Silverlight Business Application project re-add the files (XAML, CS) from the old Silverlight Business Application project Does this sound like a reasonable approach? I think it's cleaner than trying to manually alter the existing project.

• Why would Basic Auth not work with my WCF client to Java SOAP Web Service?

  - by orj

  I have a Java based web service that requires basic authentication to communicate with it. If I type the WSDL url into my browser I'm prompted for Basic Auth. Which I can get by entering the correct credentials. However using my WCF client doesn't work. I construct my WCF client like this: var binding = new BasicHttpBinding { MaxReceivedMessageSize = 2048 * 10240, Security = { Mode = BasicHttpSecurityMode.TransportCredentialOnly, Transport = { ClientCredentialType = HttpClientCredentialType.Basic, Realm = "MYREALM", ProxyCredentialType = HttpProxyCredentialType.None }, Message = { ClientCredentialType = BasicHttpMessageCredentialType.UserName, AlgorithmSuite = SecurityAlgorithmSuite.Default } } }; var client = new WebServiceClient(binding, endpoint); client.ClientCredentials.UserName.UserName = username; client.ClientCredentials.UserName.Password = password; client.DoWebServiceMethod(); I get the following exception. System.Net.WebException: The remote server returned an error: (401) Unauthorized. at System.Net.HttpWebRequest.GetResponse() at System.ServiceModel.Channels.HttpChannelFactory.HttpRequestChannel.HttpChannelRequest.WaitForReply(TimeSpan timeout) System.ServiceModel.Security.MessageSecurityException: The HTTP request is unauthorized with client authentication scheme 'Basic'. The authentication header received from the server was 'Basic realm="MYREALM"'. From what I can tell I'm doing things right. Where am I going wrong?

• tablesorter pager initial pagination

  - by vikitor

  Hi, This might sound like a very stupid question to some of you, but I assure you I've been checking through the internet and I haven't had any luck about this. My question is: is it possible to set an initial pagination number in the tablesorter pager plugin? By default it takes the 10 option, but I've tried to put a 5 as the selected option and it loads 10 anyway. If I change it and come back to the 5 it will load as said, 5, but not at the beggining. Is there any option when loading the tablesorter? My code for the tablesorter is this: $("#TST").tablesorter({ headers: { 0: { sorter: false }, 4: { sorter: false }, 5: { sorter: false }, 6: { sorter: false} }, sortList: [[1, 0], [2, 0], [3, 0]], widgets: ['zebra'] }) .tablesorterPager({ container: $("#TSTPager"), positionFixed: false //, //pagesize: 5 }); the pagesize attribute I wrote in the tablesorterPager was a test, but it doesn't do what I want it to.
