  • Process: Unable to start service com.google.android.gms.checkin.CheckinService with Intent

    - by AndyRoid
    I'm trying to build a Google map application but keep receiving this in my LogCat. I have all the permissions and meta-data set in my manifest, but am still dumbfounded by this error. Have looked everywhere on SO for this specific error but found nothing relating to com.google.android.gms.checkin A little bit about my structural hierarchy. MainActivity extends ActionBarActivity with three tabs underneath actionbar. Each tab has it's own fragment. On the gMapFragment I create a GPSTrack object from my GPSTrack class which extends Service and implements LocationListener. The problem is that when I start the application I get this message: I have all my libraries imported properly and I even added the google-play-services.jar into my libs folder. I also installed Google Play Services APKs through CMD onto my emulator. Furthermore the LocationManager lm = = (LocationManager) mContext.getSystemService(LOCATION_SERVICE); in my GPSTrack class always returns null. Why is this and how can I fix these issues? Would appreciate an explanation along with solution too, I want to understand what's going on here. ============== Code: gMapFragment.java public class gMapFragment extends SupportMapFragment { private final String TAG = "gMapFragment"; private GoogleMap mMap; protected SupportMapFragment mapFrag; private Context mContext = getActivity(); private static View view; @Override public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) { if (view != null) { ViewGroup parent = (ViewGroup) view.getParent(); if (parent != null) { parent.removeView(view); } } try { super.onCreateView(inflater, container, savedInstanceState); view = inflater.inflate(R.layout.fragment_map, container, false); setupGoogleMap();

  • WCF selfhosted service, installer class and netsh

    - by jeho
    I have a selfhosted WCF service application which I want to deploy by a msi installer package. The endpoint uses http port 8888. In order to startup the project under windows 2008 after installation I have to either run the program as administrator or have to edit the http settings with netsh: "netsh http add urlacl url=http://+:8888/ user=\Everyone" I want to edit the http settings from my installer class. Therefore I call the following method from the Install() method: public void ModifyHttpSettings() { string parameter = @"http add urlacl url=http://+:8888/ user=\Everyone"; System.Diagnostics.ProcessStartInfo psi = new System.Diagnostics.ProcessStartInfo("netsh", parameter); psi.Verb = "runas"; psi.RedirectStandardOutput = false; psi.CreateNoWindow = true; psi.WindowStyle = System.Diagnostics.ProcessWindowStyle.Hidden; psi.UseShellExecute = false; System.Diagnostics.Process.Start(psi); } This method will work for english versions of windows, but not for localized versions (The group Everyone has different names in localized versions). I have also tried to use Environment.UserName to allow access at least for the current logged on user. But this does also not work, because the installer class is run by the msi service which runs under the user SYSTEM. Hence Enviroment.UserName returns SYSTEM and that is not what I want. Is there a way to grant access to all (or at least for the current logged on) user to my selfhosted WCF service from a msi installer class?

  • ASP.NET Setting Culture with InitializeCulture

    - by Helen
    I have a website with three domains .com, .de and .it Each domain needs to default to the local language/culture of the country. I have created a base page and added an InitializeCulture Protected Overrides Sub InitializeCulture() Dim url As System.Uri = Request.Url Dim hostname As String = url.Host.ToString() Dim SelectedLanguage As String If HttpContext.Current.Profile("PreferredCulture").ToString Is Nothing Then Select Case hostname Case "www.domain.de" SelectedLanguage = "de" Thread.CurrentThread.CurrentUICulture = New CultureInfo(SelectedLanguage) Thread.CurrentThread.CurrentCulture = CultureInfo.CreateSpecificCulture(SelectedLanguage) Case "www.domain.it" SelectedLanguage = "it" Thread.CurrentThread.CurrentUICulture = New CultureInfo(SelectedLanguage) Thread.CurrentThread.CurrentCulture = CultureInfo.CreateSpecificCulture(SelectedLanguage) Case Else SelectedLanguage = "en" Thread.CurrentThread.CurrentUICulture = New CultureInfo(SelectedLanguage) Thread.CurrentThread.CurrentCulture = CultureInfo.CreateSpecificCulture(SelectedLanguage) End Select End If End Sub This is fine. The problem now occurs because we also want three language selection buttons on the home page so that the user can override the domain language. So on my Default.asp.vb we have three button events like this... Protected Sub langEnglish_Click(ByVal sender As Object, ByVal e As System.Web.UI.ImageClickEventArgs) Handles langEnglish.Click Dim SelectedLanguage As String = "en" 'Save selected user language in profile HttpContext.Current.Profile.SetPropertyValue("PreferredCulture", SelectedLanguage) 'Force re-initialization of the page to fire InitializeCulture() Context.Server.Transfer(Context.Request.Path) End Sub But of course the InititalizeCulture then overrides whatever button selection has been made. Is there any way that the InitialCulture can check whether a button click has occurred and if so skip the routine? Any advice would be greatly appreciated, thanks.

  • jquery stop image rotation on mouseover, start on mouseout / hover

    - by Matt Nathanson
    I have built a jQuery rotator to rotate through 3 divs and loop them. I would like to add the functionality on mouse over to "freeze" the current div and then start again on mouse out. I've thought about setting a variable to false at the start of the function and setting it true when it's on it's current frame but I've got my self a bit confused. I've also tried to use the hover function but when using the in and out handlers, I'm confused as to how to stop, restart the animation. function ImageRotate() { var CurrentFeature = "#container" + featureNumber; $(CurrentFeature).stop(false, true).delay(4500).animate({'top' : '330px'}, 3000); var featureNumber2 = featureNumber+1; if ( featureNumber == numberOfFeatures) {featureNumber2 = 1} var NewFeature = "#container" + featureNumber2; $(NewFeature).stop(false, true).delay(4500).animate({'top' : '0px'}, 3000); var featureNumber3 = featureNumber-1; if ( featureNumber == 1) {featureNumber3 = numberOfFeatures}; var OldFeature = "#container" + featureNumber3; $(OldFeature).stop(false, true).delay(4500).css('top' , '-330px'); setTimeout('if (featureNumber == numberOfFeatures){featureNumber = 1} else {featureNumber++}; ImageRotate2()', 7500)}; Any help would be greatly appreciated!! Thanks, Matt

  • Switch to tab by typing a substring of its name in Visual Studio 2005

    - by Vineus
    Is there a way to navigate between tabs in VS similar to the emacs iswtichb-mode or Firefox ubiquity switch tab mode (https://wiki.mozilla.org/Labs/Ubiquity/Ubiquity_0.1_Author_Tutorial#Switching_Tabs) ? In these apps, you just type a substring of the title of the tab (or buffer for emacs) to switch to this tab. For instance, to switch to a tab named "App_Code/Data/MyProgram.cs", you just invoke the tab switching command and then type "Progr" for instance to list all the tab whose name matches this string, including "MyProgram.cs". It's much easier to switch between tabs this way when you have a lot of documents open and when you now where to go (which is the case in most situation) Thank you !

  • monitoring iphone 3g/wifi bandswitch

    - by user262325
    Hello everyone I hope add the function to monitor iphone used 3g/wifi band switch. I know I can do these in my app, but I wonder if there is way to monitor all band switch usage of iPhone? I noticed that there is an app http://itunes.apple.com/ca/app/download-meter-for-wi-fi-gprs/id327227530?mt=8 It claims: Works with any carrier (iPods are supported too!). Requires no login/password to your carrier's site. Does not require Internet connection to get traffic usage statistics (works even in Airplane mode) because it gets information on traffic from the device, not a carrier; this means it won't cost you anything to view current traffic consumed, even while roaming in a location where traffic is very expensive. Allows the user to adjust consumed traffic for today or the current month to match traffic amounts reported by your carrier. Stats on the screen are updated every second. Measures traffic in real time with up to byte precision. Separates traffic into incoming and outgoing, Wi-Fi traffic and mobile Internet traffic. It looks like it gets the band switch info from carrier site, but they also said it gets info from device. I am really confused. Welcome any comment. Thanks interdev

  • OpenGL ES Simple Undo Last Drawing

    - by Erika
    Hi Everyone, I am trying to figure out how to implement a simple "undo" of last drawing action on the iPhone screen. I draw by first preparing the frame buffer: [EAGLContext setCurrentContext:context]; glBindFramebufferOES(GL_FRAMEBUFFER_OES, viewFramebuffer); I then prepare the vertex array and draw this way: glVertexPointer(2, GL_FLOAT, 0, vertexBuffer); glDrawArrays(GL_POINTS, 0, vertexCount); glBindRenderbufferOES(GL_RENDERBUFFER_OES, viewRenderbuffer); [context presentRenderbuffer:GL_RENDERBUFFER_OES]; How do I simple undo this last action? There has to be a way to save previous state or an built-in OpenGL ES function, I would think. Thanks

  • Create your own custom browser

    - by ShoX
    Hi, I want to shape my own browser or at least modify a existing one so far that it meets my needs. I want a fast browser (starting and running, not necessarily faster rendering) without any stuff I don't use and simple productive navigation (like Firefox + Vimperator + Tree Style Tab), only much more integrated into each other and a different GUI. I was thinking about just looking into the current two top browsers chrome and firefox (open-source wise) and branch my own smaller version out of it. By just using WebKit or Gecko I will have to implement all the Connection-stuff, too, but I really am not interested in doing that. So my questions are: Does it make sense to start off with a current browser and strip off certain features and the frontend and replace it with my own code? Chrome or Firefox? Which one is less complex? I don't care much about Plugins and Extensions, so they aren't they pretty much even in features otherwise? Thanks for your answers p.s.: It's a just-for-fun at-home project, so please no "just use the browsers..."-stuff...

  • iphone - making the CGAffineTransform permanent

    - by Mike
    I am banging my head on the wall here due to this problem: When I create a UIImageView this view has a certain orientation and size. Lets call this state "A". This view responds to taps. It can be dragged around the screen. At some point in the code I apply a CGAffineTransform to the view. Does not matter if the affine is a scale, a rotation, a translation or a combination of all. Does not matter also if the transform is absolute or relative. Not to mention the device can change its orientation and the view is autorotated to the correct orientation (that we can cay is a kind of rotation or transformation applied to the view). The problem is: the moment I touch that object or try to animate its transparency or any other parameter, it "remembers" the state "A" and does all animations from that state, not from current state. If I simply touch the view, it returns instantly to state "A". The code is not doing it by itself. It is an annoying "gift" from Apple. How to I make a view assume its current state of transformations as the reset or initial state? In other words, how do I make a view forget its past transformations or states? The only way I know is recreating the view, but this is a ridiculous way of doing this. Is there any way to make this work as I described? thanks

  • Mercurial Tagging/Branching Strategy

    - by Tony Trozzo
    My current project is broken down into 3 parts: Website, Desktop Client, and a Plug-in for a third party program. We had started out originally with Subversion for our source control but decided to try Mercurial after reading Joel Spolsky's final post. Considering we haven't really used the majority of svn's potential before, we figured starting fresh with some basic ideas of how source control worked would make this transition easy. However, after setting up our initial repository, we're lost as to how tagging and branching should work on a project like this. Essentially, we're working on all 3 of these parts at the same time. We want a release to be a combination of the 3 parts. Currently we're working in one repository. For the Plug-in part, we have the first iteration finished which we've been referring to as Plug-In v0.1. For the first official build of the other two parts, we'd also like to refer to them as Website v0.1 and Desktop Client v0.1. When all three parts are at v0.1, we'd like to have a Full Project v0.1. Our problem is we're not sure how to manage all of this in the Hg repository. Would the best way to handle this be to create 3 separate repositories for the 3 stable versions and then 3 more repositories for the current developments? Currently we have this all in one repository. Should we do this in branches (are branches any different from cloning repositories?) and tags? Any help is greatly appreciated.

  • How to use drag and drop within a UIScrollView

    - by user249488
    I am trying to drag and drop UIViews within a UIScrollView. I'd like the UIScrollView to scroll if I drag a UIView so that it intersects the top or bottom of the ScrollView. If it touches the top, it should scroll up. If it touches the bottom, it should scroll down. Once the UIView is moved such that it is no longer intersecting the top or bottom, the scrolling should stop. The first approach I tried was to start an NSTimer whenever I detected that the UIView intersected with the top or bottom of the scrollview. The timer would scroll the UIScrollView bit by bit until it was invalidated. This resulted in very jerky scrolling, since there is no way to predict when the timers will fire. My current approach is to simply scroll all the way to the top or bottom of the ScrollView, like this: [UIView beginAnimations:nil context:NULL]; [UIView setAnimationCurve:UIViewAnimationCurveEaseInOut]; [UIView setAnimationDuration:1.0]; [self.parentScrollview setContentOffset:newOffset animated:NO]; [UIView commitAnimations]; In order to stop scrolling, I try to determine the position of the touch in the touchesMoved: delegate, and use that to calculate the contentOffset to use for the scrollView. The problem is, when I try to get the location in the view via [[touches anyObject] locationInView:self], I get the final end location, rather than the current location. I'm guessing that's because the contentOffset on the scrollView is set immediately. Is there a way to get the actual location of a touch in a situation like this? Or any other way to set the contentOffset when I interrupt the scrolling animation?

  • C#: How to set AsyncWaitHandle in Compact Framework?

    - by Thorsten Dittmar
    Hi, I'm using a TcpClient in one of my Compact Framework 2.0 applications. I want to receive some information from a TCP server. As the Compact Framework does not support the timeout mechanisms of the "large" framework, I'm trying to implement my own timeout-thing. Basically, I want to do the following: IAsyncResult result = client.BeginRead(buffer, 0, size, ..., stream); if (!result.AsyncWaitHandle.WaitOne(5000, false)) // Handle timeout private void ReceiveFinished(IAsyncResult ar) { NetworkStream stream = (NetworkStream)ar.AsyncState; int numBytes = stream.EndRead(ar); // SIGNAL IASYNCRESULT.ASYNCWAITHANDLE HERE ... HOW?? } I'd like to call Set for the IAsyncResult.AsyncWaitHandle, but it doesn't have such a method and I don't know which implementation to cast it to. How do I set the wait handle? Or is it automatically set by calling EndRead? The documentation suggests that I'd have to call Set myself... Thanks for any help!

  • Lisp Style question label local functions or not?

    - by Andrew Myers
    I was wondering if there is a standard practice regarding the use of labels in Lisp. I've been messing around with a Lisp implementation of the algorithm described in the first answer here http://stackoverflow.com/questions/352203/generating-permutations-lazily My current version uses labels to break out portions of functionality. (defun next-permutation (pmute) (declare (vector pmute)) (let ((len (length pmute))) (if (> len 2) (labels ((get-pivot () (do ((pivot (1- len) (1- pivot))) ((or (= pivot 0) (< (aref pmute (1- pivot)) (aref pmute pivot))) pivot))) (get-swap (pivot) (let ((swp (1- len))) (loop for i from (1- len) downto pivot do (if (or (and (> (aref pmute i) (aref pmute (1- pivot))) (< (aref pmute i) (aref pmute swp))) (< (aref pmute swp) (aref pmute (1- pivot)))) (setf swp i))) swp)) (next (swp pivot) (rotatef (aref pmute (1- pivot)) (aref pmute swp)) (reverse-vector pmute pivot (1- len)))) (let ((piv (get-pivot))) (if (> piv 0) (next (get-swap piv) piv) nil)))))) Since each label is only called once I was wondering if this is considered bad practice since the only reason to do it in this case is for aesthetic reasons. I would argue that the current version with labels is clearer but that may go against common wisdom that I'm not aware of, being new to Lisp.

  • Passing parameters between interrupt handlers on a Cortex-M3 ...

    - by Captain NedD
    I'm building a light kernel for a Cortex-M3. From a high priority interrupt I'd like to invoke some code to run in a lower priority interrupt and pass some parameters along. I don't want to use a queue to post work to the lower priority interrupt. I just have a buffer and size to pass to it. In the proramming manual it says that the SVC interrupt handler is synchronous which presumably means that if you invoke it from an interrupt that's a lower priority than SVC's handler it gets called immediately (the upshot of this being that you can pass parameters to it as though it were a function call (a little like the BIOS calls in MS-DOS)). I'd like to do it the other way: passing parameters from a high priority interrupt to a lower priority one (at the moment I'm doing it by leaving the parameters in a fixed location in memory). What's the best way to do this (if at all possible)? Thanks,

  • Invalid Cast Exception ASP.NET C#

    - by Shadow Scorpion
    I have a problem in this code: public static T[] GetExtras <T>(Type[] Types) { List<T> Res = new List<T>(); foreach (object Current in GetExtras(typeof(T), Types)) { Res.Add((T)Current);//this is the error } return Res.ToArray(); } public static object[] GetExtras(Type ExtraType, Type[] Types) { lock (ExtraType) { if (!ExtraType.IsInterface) return new object[] { }; List<object> Res = new List<object>(); bool found = false; found = (ExtraType == typeof(IExtra)); foreach (Type CurInterFace in ExtraType.GetInterfaces()) { if (found = (CurInterFace == typeof(IExtra))) break; } if (!found) return new object[] { }; foreach (Type CurType in Types) { found = false; if (!CurType.IsClass) continue; foreach (Type CurInterface in CurType.GetInterfaces()) { try { if (found = (CurInterface.FullName == ExtraType.FullName)) break; } catch { } } try { if (found) Res.Add(Activator.CreateInstance(CurType)); } catch { } } return Res.ToArray(); } } When I'm using this code in windows application it works! But I cant use it on ASP page. Why?

  • Understanding the Silverlight Dispatcher

    - by Matt
    I had a Invalid Cross Thread access issue, but a little research and I managed to fix it by using the Dispatcher. Now in my app I have objects with lazy loading. I'd make an Async call using WCF and as usual I use the Dispatcher to update my objects DataContext, however it didn't work for this scenario. I did however find a solution here. Here's what I don't understand. In my UserControl I have code to call an Toggle method on my object. The call to this method is within a Dispatcher like so. Dispatcher.BeginInvoke( () => _CurrentPin.ToggleInfoPanel() ); As I mentioned before this was not enough to satisfy Silverlight. I had to make another Dispatcher call within my object. My object is NOT a UIElement, but a simple class that handles all its own loading/saving. So the problem was fixed by calling Deployment.Current.Dispatcher.BeginInvoke( () => dataContext.Detail = detail ); within my class. Why did I have to call the Dispatcher twice to achieve this? Shouldn't a high-level call be enough? Is there a difference between the Deployment.Current.Dispatcher and the Dispatcher in a UIElement?

  • Can you access registers from python functions in vim

    - by Michael Anderson
    It seems vims python sripting is designed to edit buffer and files rather than work nicely with vims registers. You can use some of the vim packages commands to get access to the registers but its not pretty. My solution for creating a vim function using python that uses a register is something like this. function printUnnamedRegister() python >> EOF print vim.eval('@@') EOF Setting registers may also be possible using something like function setUnnamedRegsiter() python >> EOF s = "Some \"crazy\" string\nwith interesting characters" vim.command('let @@="%s"' % myescapefn(s) ) EOF However this feels a bit cumbersome and I'm not sure exactly what myescapefn should be. So I've never been able to get the setting version to work properly. So if there's a way to do something more like function printUnnamedRegister() python >> EOF print vim.getRegister('@') EOF function setUnnamedRegsiter() python >> EOF s = "Some \"crazy\" string\nwith interesting characters" vim.setRegister('@',s) EOF Or even a nice version of myescapefn I could use then that would be very handy.

  • Map/Reduce on an array of hashes in CouchDB

    - by sebastiangeiger
    Hello everyone, I am looking for a map/reduce function to calculate the status in a Design Document. Below you can see an example document from my current database. { "_id": "0238f1414f2f95a47266ca43709a6591", "_rev": "22-24a741981b4de71f33cc70c7e5744442", "status": "retrieved image urls", "term": "Lucas Winter", "urls": [ { "status": "retrieved", "url": "http://...." }, { "status": "retrieved", "url": "http://..." } ], "search_depth": 1, "possible_labels": { "gender": "male" }, "couchrest-type": "SearchTerm" } I'd like to get rid of the status key and rather calculate it from the statuses of the urls. My current by_status view looks like the following: function(doc) { if (doc['status']) { emit(doc['status'], null); } } I tried some things but nothing actually works. Right now my Map Function looks like this: function(doc) { if(doc.urls){ emit(doc._id, doc.urls) } } And my Reduce Function function(key, value, rereduce){ var reduced_status = "retrieved" for(var url in value){ if(url.status=="new"){ reduced_status = "new"; } } return reduced_status; } The result is that I get retrieved everywhere which is definitely not right. I tried to narrow down the problem and it seems to be that value is no array, when I use the following Reduce Function I get length 1 everywhere, which is impossible because I have 12 documents in my database, each containing between 20 to 200 urls function(key, value, rereduce){ return value.length; } What am I doing wrong? (I know I want you to write code for me and I'm feeling guilty, but right now I do the calculation of the statuses in ruby after getting the data from the database. It would be nice to already get the right data from the database)

  • Rendering formatted text in a direct3d application

    - by Fire Lancer
    I need to render some formatted text (colours, different font sizes, underlines, bold, etc) however I'm not sure how to go about doing it. D3DXFont only allows text of a single font/size/weight/colour/etc to be rendered at once, and I cant see a practical way to "combine" multiple calls to ID3DXFont::DrawText to do such things... I looked around and there doesn't seem to be any existing libraries that do these things, but I have no idea how to implement such a text renderer, and I couldn't even find any documentation on how such a text render would work, only rendering simple fixed width, ASCII bitmap fonts which looking at it is probably an entirely different approach that is only suitable for rendering simple blocks of text where Unicode is not important. If there's no direct3d font renders capable of doing this, is there any other renderers (eg for use in rendering rich text in a normal window), and would rendering those to a texture in RAM, then uploading that to the video card to render onto the back buffer yield reasonable performance?

  • OCUnit & NSBundle

    - by kpower
    I created OCUnit test in concordance with "iPhone Development Guide". Here is the class I want to test: // myClass.h #import <Foundation/Foundation.h> #import <UIKit/UIKit.h> @interface myClass : NSObject { UIImage *image; } @property (readonly) UIImage *image; - (id)initWithIndex:(NSUInteger)aIndex; @end // myClass.m #import "myClass.m" @implementation myClass @synthesize image; - (id)init { return [self initWithIndex:0]; } - (id)initWithIndex:(NSUInteger)aIndex { if ((self = [super init])) { NSString *name = [[NSString alloc] initWithFormat:@"image_%i", aIndex]; NSString *path = [[NSBundle mainBundle] pathForResource:name ofType:@"png"]; image = [[UIImage alloc] initWithContentsOfFile:path]; if (nil == image) { @throw [NSException exceptionWithName:@"imageNotFound" reason:[NSString stringWithFormat:@"Image (%@) with path \"%@\" for current index (%i) wasn't found.", [name autorelease], path, aIndex] userInfo:nil]; } [path release]; } return self; } - (void)dealloc { [image release]; [super dealloc]; } @end And my unit-test (LogicTests target): // myLogic.m #import <SenTestingKit/SenTestingKit.h> #import <UIKit/UIKit.h> #import "myClass.h" @interface myLogic : SenTestCase { } - (void)testTemp; @end @implementation myLogic - (void)testTemp { STAssertNoThrow([[myClass alloc] initWithIndex:0], "myClass initialization error"); } @end All necessary frameworks, "myClass.m" and images added to target.

I've also checked my project folder (build/Debug-iphonesimulator/LogicTests.octest/) - there are LogicTests, Info.plist and necessary image files (image_0.png is one of them). What's wrong?

  • Looking for input on GWT / MVP action w/o browser history change

    - by user198313
    Hello there, I am trying to develop a GWT app with the MVP pattern. So far so good except for one specific case of actions: actions that do not change the url (no browser history change). In the GWT MVP pattern, events are sent from presenters, the an app controller catches them and update the browser history. If the history has changed then the view updates. ** MVP with history change (Works well)** Current URL is /list User clicks on contactdelete button. Fire DeleteContactAction event. App controller catches, change history to 'delete' onValueChange is called if (token.equals("delete")) delete contact screen, then delete contact Fire ContactDeletedEvent app controller catches and change the history to list onValueChange is called: contact list refreshes GWT MVP pattern for dialog box w/o history changes ** Issue ** - I use a dialog box and I don't want to change the browser history, so here is the problem: Current URL is /list User clicks on contactdelete button. Contact is deleted Fire ContactDeletedEvent. App controller catches, change history to 'list' **onValueChange is NOT called** because url is already /list and there is no change # problem: contact list does not refresh Question: does anyone know a pattern to implement this in the context of MVP? Any help / idea appreciated.

  • How to remove old indexed URLs from Google?

    - by Gok Demir
    I used Cs-cart for a site. Default installation SEO is not suitable for Turkish accented characters such as "ö" which maps to automatically "ae". Then I modified the php code and now it substitutes "ö" with "o" and "s"-"s" etc. Also I changed a category name to a better one. My problem is, google indexed both previous versions and new versions. Previous wrong urls gives 404 error. I used sitemap addon and send it to google and sitemap does not include wrong urls. However these old urls are still indexed on google. What can I do to remove them. For example http://www.google.com.tr/search?q=%C3%A7ak%C4%B1l+ta%C5%9Flar%C4%B1ndan+babil+site:eeski.com&hl=tr&client=firefox-a&hs=Z31&rls=com.ubuntu:en-US:official&filter=0 gives two top results old wrong url leads to 404: http://www.eeski.com/kitap-dergi/bilim-ve-teknik/cakl-talarndan-babil-kulesine-rakamlarn-evrensel-tarihi-ii.html right current url: http://www.eeski.com/kitap/bilim-ve-teknik/cakil-taslarindan-babil-kulesine-rakamlarin-evrensel-tarihi-ii.html What could I make google only index current urls stated on sitemap?

  • emacs indentation problem

    - by Gauthier
    I'm really trying to switch to emacs, but learning to setup the environment is a real pain. Everybody says it's worth it, so I just continue. I want my c code to be implemented that way: if(asdf) { asdr = 1; } Depending on the current standard (I know, don't get me started), could be: if(asdf) { asdr = 1; } I can't seem to change the indentation size from 2, it always looks like the GNU standard: if(asdf) { asdr = 1; } , which I dislike. Here is what I have put in my .emacs: ; Warn in C for while();, if(x=0), ... (global-cwarn-mode 1) ; no electric mode in c (c-toggle-electric-state -1) ; indent the current line only if the cursor is at the beginning of the line (setq-default c-tab-always-indent nil) (setq-default c-indent-level 4) (setq-default tab-width 4) (setq-default indent-tabs-mode nil) (setq-default c-basic-offset 4) (setq-default c-basic-indent 4) ; These commands I read about on the web, but they don't work? ;(highlight-tabs) ;(highlight-trailing_whitespace) This did not help, I have still the GNU indent. Anyone?
