  • Looping through a method without for/foreach/while

    - by RichK
    Is there a way of calling a method/lines of code multiple times not using a for/foreach/while loop? For example, if I were to use to for loop: int numberOfIterations = 6; for(int i = 0; i < numberOfIterations; i++) { DoSomething(); SomeProperty = true; } The lines of code I'm calling don't use 'i' and in my opinion the whole loop declaration hides what I'm trying to do. This is the same for a foreach. I was wondering if there's a looping statement I can use that looks something like: do(6) { DoSomething(); SomeProperty = true; } It's really clear that I just want to execute that code 6 times and there's no noise involving index instantiating and adding 1 to some arbitrary variable. As a learning exercise I have written a static class and method: Do.Multiple(int iterations, Action action) Which works but scores very highly on the pretentious scale and I'm sure my peers wouldn't approve. I'm probably just being picky and a for loop is certainly the most recognisable, but as a learning point I was just wondering if there (cleaner) alternatives. Thanks. (I've had a look at this thread, but it's not quite the same) http://stackoverflow.com/questions/2248985/using-ienumerable-without-foreach-loop

  • Ruby, Python, or PHP?

    - by Gabe
    And so we return to the age old question - but with a few twists. This morning, I searched and read up on which web development language to learn first. I'm thinking Ruby, Python, or perhaps PHP. But I have a few questions before deciding. Background: I'm a year into C++ (through school), but want to get into web development. I have all summer to commit to one language, learn it, do some projects, get up some websites, and so on. Now my questions (and these are assuming that I should choose between Ruby, Python, and PHP - if I should choose a different language, let me know.): I hope to use whichever language I learn for websites/web apps. Some of the threads on stackoverflow suggested Python was the best overall language, but others were unanimous that Ruby was best specifically for web development. For a first language suited towards web development, which language do you recommend, and why? This might tie into the first question, but which language looks most promising for future work, future personal projects, and basically the future in general? I'm just a freshman in college. Ideally, the language I choose would be on the rise, community-wise and opportunity-wise. (One reason I'm leaning towards Ruby is that it seems a lot of the newer tech startups/successes are using it.)

  • Why does the BackgroundWorker in WPF need Thread.Sleep to update UI controls?

  • 2-column table with two foreign keys. Performance/design question.

    - by Emanuel
    Hello everyone! I recently ran into a quite complex problem and after looking around a lot I couldn't find a solution to it. I've found answers to my questions many times before on stackoverflow.com, so I decided to post here. So I'm making a user/group managment system for a web-based project, and I'm storing all related data into a postgreSQL database. This system relies on three tables: USERS GROUPS GROUP_USERS The two first tables simply define all the users and all the groups on the site, and the last table, GROUP_USERS, stores the groups every user is part of. It only has two columns: USER_ID GROUP_ID Since every user can be a member of several groups, I decided to make a separate table for this purpose, rather than storing a comma separated column in the USERS-table. Now, both columns are foreign keys, and I want to make them both primary keys as well, this since each combination of USER_ID and GROUP_ID has to be unique, and if I give them the constraint UNIQUE pgAdmin tells me that each table should have at least one Primary key. But now I am stuck with what seems to be a lot of indexes and relations to a very small table only containing numbers. In the end, I want this table to be as fast as possible, even if containing tens of thousands of rows. Size on disk shouldn't be a problem since its just all numbers anyway, but it feels quite stupid to have a full-sized index refering to a smaller table. Should I stick with my current solution, store comma-separated values in a column in the USERS-table or is there any other solution I should be aware of. PS. I don't want to use an array-column, even if they are supported by postgreSQL. I want to be as generic as possible so I can switch database later on, if necessary. EDIT: I other words, will using a compound primary key and two foreign keys in one table with only two columns have a negative impact on performance rather than the opposite due to the size of the generated index? Thank you!

  • CSS H4 hover style

    - by user1750613
    I tried many css from other places and stackoverflow, but somehow I can not make it done. I'm very new to css, and using Joomla and a template. I'm using custom.css folder for certain customizations on style. Here is I want to do: I want to style h4 when it is a link. For example, I'm creating a custom html module, have a list in the content. And in the content I'm giving each, h5 style, and a link to it to a certain page in the site. What I want to achieve is to have this list with color blue. And when mouse over-hover to have underline and still the same color. And when clicked back to the original position with no underline and no color change. (the same color in every situation, just underline when you are over it.) I tried these h5, h5 a, h5 a: hover, h5 .contentheading a, and so on... In one instance, it was working with : h5 { font-family: arial, sans-serif; font-size: 1.3em; font-weight: bold; } h5 a { color: #0088CC; } h5 a: hover { color: #0088CC; text-decoration: underline; } As I read I should use 'a' when the heading is a link. But now something is overriding it, I'm completely lost now. I see a:hover style in the inspection. I want to use this h5 in several content (in custom modules) when I want to style a content as a list to links. And I thought it will be practical to have one heading with a certain style so that I can use it with flexibility. Thanks a lot, any help will be great : )

  • ASP.NET DropDownList control doesn't postback correctly inside of UserControl

    - by RichardAZ
    I have a situation where a DropDownList control is not posting back correctly. The AutoPost property is set to true, so the postback does happen, but the SelectedValue is not set to the correct value. In addition, the onSelectedIndexChanged event doesn't fire. The exact same code works perfect fine on an ASPX page, but does not work in a ASCX control. I have tried all the obvious things, I hope, trying to figure this one out, but no luck so far. I have even investigated what comes back in Request.Form["__EVENTTARGET"] and __EVENTARGUMENT. __EVENTTARGET does point to the drop down list, but the argument is empty. Can the folks of StackOverflow help lead me in the right direction to debug this issue. Of course, it is further complicated by master pages and the usual overcomplication of ASP.NET. Here is the code: <div> <asp:DropDownList ID="testDrop" runat="server" AutoPostBack="true" EnableViewState="true" onselectedindexchanged="testDrop_SelectedIndexChanged"> <asp:ListItem Value="1" Text="1">1</asp:ListItem> <asp:ListItem Value="2" Text="2">2</asp:ListItem> </asp:DropDownList> </div> And here is the generated html: <select id="ctl00_MainContent_rptAccordion_ctl00_statControl_testDrop" onchange="javascript:setTimeout('__doPostBack(\'ctl00$MainContent$rptAccordion$ctl00$statControl$testDrop\',\'\')', 0)" name="ctl00$MainContent$rptAccordion$ctl00$statControl$testDrop"> <option value="1" selected="selected">1</option> <option value="2">2</option> THANKS!

  • Undefined Variable? But I defined it...

    - by Rob
    Well before anyone claims that theres a duplicate question... (I've noticed that people who can't answer the question tend to run and look for a duplicate, and then report it.) Here is the duplicate you are looking for: http://stackoverflow.com/questions/2481382/php-claims-my-defined-variable-is-undefined However, this isn't quite a duplicate. It gives me a solution, but I'm not really looking for this particular solution. Here is my problem: Notice: Undefined variable: custom Now here is my code: $headers = apache_request_headers(); // Request the visitor's headers. $customheader = "Header: 7ddb6ffab28bb675215a7d6e31cfc759"; //This is what the header should be. foreach ($headers as $header => $value) { $custom .= "$header: $value"; } Clearly, $custom is defined. According to the other question, it's a global and should be marked as one. But how is it a global? And how can I make it a (non-global)? The script works fine, it still displays what its supposed to and acts correctly, but when I turn on error messages, it simply outputs that notice as well. I suppose its not currently necessary to fix it, but I'd like to anyway, as well as know why its doing this.

  • find and replace values in csv using PHP

    - by peirix
    I'd think there was a question on this already, but I can't find one. Maybe the solution is too easy... Anyway, I have a csv and want to let the user change the values based on a name. I've already sorted out creating new name+value-pairs using the fopen('a') mode, using jQuery to send the AJAX call with newValue and newName. But say the content looks like this: host|http:www.stackoverflow.com folder|/questions/ folder2|/users/ And now I want to change the folder value. So I'll send in folder as oldName and /tags/ as newValue. What's the best way to overwrite the value? The order in the list doesn't matter, and the name will always be on the left, followed by a |(pipe), the value and then a new-line. My first thought was to read the list, store it in an array, search all the [0]'s for oldName, then change the [1] that belongs to it, and then write it back to a file. But I feel there is a better way around this? Any ideas? Maybe regex?

  • License of popular dictionary word lists (e.g. SOWPODS, TWL)? Copyright? Trademarks?

    - by BobbyJim
    (I'm not sure if this off-topic. I found a lot of voted-up questions about software licenses and this is related. Plus, I'm sure many of us have had the situation that we need to use a dictionary in our code) I'm making a (maybe commercial) word game and need to use a good word dictionary for checking words. The most common dictionaries to use are the SOWPODS or TWL lists that are used Scrabble tournaments; see here: http://www.scrabblist.com/ (I have nothing to do with this site by the way). I've seen loads of websites offering these two dictionaries for download and loads of word games advertise that they use them. However, I cannot find any licensing terms attached to these dictionaries wherever I download them. For the players of my game, I'd want to say what dictionary I'm using (e.g. "this game uses SOWPODS"). However, I'm nervous about what I can do legally. Does anyone know about if you can copyright lists of words? Does anyone know the licenses of TWL and SOWPODS? TWL and SOWPODS don't seem to have trademarks on them but I'd like to know for sure. I cannot find any good sources for this information. EDIT: Great, now the top result for "SOWPODS license" is my stackoverflow question. :)

  • how to make it easy for users to register at my site?

    - by rob
    I want to make it dirt simple for users coming to my site to register so they can post comments, vote on things, etc. I would like for them to be able to use their facebook id, twitter id, yahoo mail id, gmail id, AIM id, msn id, or whatever else people are likely to have (not necessarily all of those, but the more the better). I want my mom to be able to do it in 30 seconds or less. (that is, no "enter your open id url here" type thing that would confuse her). I prefer they not have to pick a unique name, as that gets annoying as the site gets more users and it gets hard to find one that is unique. What is the best option here? I'm not quite sure about OpenId vs. OAuth, and whether there are other options. And I'd like it to be as simple for me, the developer, as possible (of course!). I don't want to spend forever learning some protocol, nor have to structure my whole app around this. It would be great if there was a site with sample code that is pretty easy to drop in. BTW, StackOverflow is a good example of a site that was easy for me to register for.

  • What is the best (Windows) program launcher?

    - by AR
    One of the biggest general productivity boosters I've used is a good program launcher. I was a long-time user of SlickRun, and I've tried a few others. My current favorite is Executor - by far the best I've used. Other options: Executor: My current favorite Vista Start Menu: Pretty good, actually, but Executor is similar (binds to Win+Z) and much more flexible. Quicksilver: For Macs only, but it seems to be the gold standard against which most other launchers are measured. Google Desktop: Press Ctrl+Ctrl and it's a quick launcher! AutoHotKey: Much,much more than just a launcher - more than I need, really. SlickRun: simple and unobtrusive Launchy: Seems to be the launcher of choice for many StackOverflow users :) Colibri: "Type Ahead - Information at the tip of your wings". Quite a cool concept. Many, many others. Scott Hanselman outlines some more here. I realize that everyone will have their own preferences, but the question is: is there anything that really stands out in terms of speed, features, and especially productivity increase?

  • How do you program a custom WordPress plug-in?

    - by James
    I have seen several WordPress plug-ins for adding a "quote of the day" feature (or something similar) to your blog. How do you create a customized one? I'm looking for something that will pull a daily entry from a list/database of my creation. I apologize if my question is not detailed enough. Still a newbie with WordPress. PART 2: Thanks for your prompt and on-point responses. With your responses and some additional research, I'm able to fine-tune my question. What I wish to accomplish is something similar to Amazon's Deal of the Day widget. Except, in my case, it will simply be a title and a corresponding link. My presumption is that I will set up a database and (using php or something similar) have the information drawn from the database and displayed in my WP sidebar. Additionally, I forgot to mention the time element. I want the displayed info to update once a day, at or around the same time each day. Any ideas? Thanks again. I'm so glad I found stackoverflow.

  • Difference between these two functions that find Palindromes....

    - by Moin
    I wrote a function to check whether a word is palindrome or not but "unexpectedly", that function failed quite badly, here it is: bool isPalindrome (const string& s){ string reverse = ""; string original = s; for (string_sz i = 0; i != original.size(); ++i){ reverse += original.back(); original.pop_back(); } if (reverse == original) return true; else return false; } It gives me "string iterator offset out of range error" when you pass in a string with only one character and returns true even if we pass in an empty string (although I know its because of the intialisation of the reverse variable) and also when you pass in an unassigned string for example: string input; isPalindrome(input); Later, I found a better function which works as you would expect: bool found(const string& s) { bool found = true; for (string::const_iterator i = s.begin(), j = s.end() - 1; i < j; ++i, --j) { if (*i != *j) found = false; } return found; } Unlike the first function, this function correctly fails when you give it an unassigned string variable or an empty string and works for single characters and such... So, good people of stackoverflow please point out to me why the first function is so bad... Thank You.

  • Objective-C Result from a Static Method saved to class instance variable giving "EXC_BAD_ACCESS" when used.

    - by KinGBin
    I am trying to store the md5 string as a class instance variable instead of the actual password. I have a static function that will return a md5 string which I'm trying to store in an instance variable instead of the actual password. I have the following setter for my class instance variable: -(void)setPassword:(NSString *)newpass{ if(newpass != password){ password = [utils md5HexDigest:newpass]; } } This will pass back the correct md5 string and save it to the password variable in my init function: [self setPassword:pword];. If I call another instance method and try to access self.password" I will get "EXC_BAD_ACCESS". I understand that the memory is getting released, but I have no clue to make sure it stays. I have tried alloc init with autorelease with no luck. This is the md5HexDigest function getting called during the init (graciously found in another stackoverflow question): + (NSString*)md5HexDigest:(NSString*)input { const char* str = [input UTF8String]; unsigned char result[CC_MD5_DIGEST_LENGTH]; CC_MD5(str, strlen(str), result); NSMutableString *ret = [NSMutableString stringWithCapacity:CC_MD5_DIGEST_LENGTH*2]; for(int i = 0; i<CC_MD5_DIGEST_LENGTH; i++) { [ret appendFormat:@"%02x",result[i]]; } return ret; } Any help/pointers would be greatly appreciated. I would rather have the md5 string saved in memory than the actual password calling the md5 every time I needed to use the password. Thanks in advance.

  • JavaScript: supposed to execute functions sequentially, not actually doing so?

    - by AP257
    I'm seeing a lot of answers on StackOverflow that say that JavaScript executes code sequentially, but I can actually see my own JavaScript not doing so. From the following code: function centre_map(lat, lng, zoom_level) { alert('centre_map'); map = new GMap2(document.getElementById('map_canvas')); var latlng = new GLatLng(lat, lng); map.setCenter(latlng, zoom_level); } function add_markers_within_bounds() { alert('add_markers_within_bounds'); // add numerous BLUE markers within map bounds using MarkerClusterer } function add_marker(lat, lng, place_name, grid, county) { alert('add_marker'); // add one ordinary RED Google Maps marker } centre_map('{{lat}}', '{{lng}}', 12); add_markers_within_bounds('{{grid}}', '{{place_name}}'); add_marker('{{lat}}', '{{lng}}', '{{place_name}}', '{{grid}}', '{{county}}'); I get the following sequence of events: 'centre_map' alert 'add_markers_within_bounds' alert 'add_marker' alert individual RED marker appears on map (i.e. add_marker renders) multiple BLUE markers appear on map (i.e. add_markers_within_bounds renders) Why doesn't add_markers_within_bounds complete before add_marker gets under way: and how can I make it do so? I know that one way might be to call add_marker from within add_markers_within_bounds, but for various reasons I'd rather keep it as a separate function.

  • C++ std::vector memory/allocation

    - by aaa
    from a previous question about vector capacity, http://stackoverflow.com/questions/2663170/stdvector-capacity-after-copying, Mr. Bailey said: In current C++ you are guaranteed that no reallocation occurs after a call to reserve until an insertion would take the size beyond the value of the previous call to reserve. Before a call to reserve, or after a call to reserve when the size is between the value of the previous call to reserve and the capacity the implementation is allowed to reallocate early if it so chooses. So, if I understand correctly, in order to assure that no relocation happens until capacity is exceeded, I must do reserve twice? can you please clarify it? I am using vector as a memory stack like this: std::vector<double> memory; memory.reserve(size); memory.insert(memory.end(), matrix.data().begin(), matrix.data().end()); // smaller than size size_t offset = memory.size(); memory.resize(memory.capacity(), 0); I need to guarantee that relocation does not happen in the above. thank you. ps: I would also like to know if there is a better way to manage memory stack in similar manner other than vector

  • Rails: update_attribute vs update_attributes

    - by Sam
    Object.update_attribute(:only_one_field, "Some Value") Object.update_attributes(:field1 => "value", :field2 => "value2", :field3 => "value3") Both of these will update an object without having to explicitly tell AR to update. Rails API says: for update_attribute Updates a single attribute and saves the record without going through the normal validation procedure. This is especially useful for boolean flags on existing records. The regular update_attribute method in Base is replaced with this when the validations module is mixed in, which it is by default. for update_attributes Updates all the attributes from the passed-in Hash and saves the record. If the object is invalid, the saving will fail and false will be returned. So if I don't want to have the object validated I should use update_attribute. What if I have this update on a before_save, will it stackoverflow? My question is does update_attribute also bypass the before save or just the validation. Also, what is the correct syntax to pass a hash to update_attributes... check out my example at the top.

  • Easy HTTPS to PHP script

    - by Tom
    Hi, here is my scenario: I have a website with php, mySQL. I have a software application that has a login screen and sends usernames and passwords over the web by http: public String GetWebPageSource(String pURL) { try { byte[] vReceivedBytes = null; using (System.Net.WebClient vWebClient = new System.Net.WebClient()) { vReceivedBytes = vWebClient.DownloadData(pURL); } int vBomLen = 3; byte[] vStrippedBytes = new byte[vReceivedBytes.Length - vBomLen]; Array.Copy(vReceivedBytes, vBomLen, vStrippedBytes, 0, vReceivedBytes.Length - vBomLen); return System.Text.Encoding.UTF8.GetString(vStrippedBytes); } catch (Exception e) { Console.WriteLine(e.Message); return null; } } So to send a username and password I would write: GetWebPageSource("http://mywebsite.com/Login.php?username=stackoverflow&password=iscool") and the php file would spit out some text saying whether the password is accepted or denied. However this is NOT secure. So I want to make it secure... https. How easy is it to integrate https? How much will the code change? How much do I have to handle? What is transparent to me. Do I have to check if a cookie already exists and if not write the methods for authentication or is there librarys already provided that will do it for me?

  • Dealloc'd Predicate crashing iPhone App!

    - by DVG
    To preface, this is a follow up to an inquiry made a few days ago: http://stackoverflow.com/questions/2981803/iphone-app-crashes-when-merging-managed-object-contexts Short Version: EXC_BAD_ACCESS is crashing my app, and zombie-mode revealed the culprit to be my predicate embedded within the fetch request embedded in my Fetched Results Controller. How does an object within an object get released without an explicit command to do so? Long Version: Application Structure Platforms View Controller - Games View Controller (Predicated upon platform selection) - Add Game View Controller When a row gets clicked on the Platforms view, it sets an instance variable in Games View for that platform, then the Games Fetched Results Controller builds a fetch request in the normal way: - (NSFetchedResultsController *)fetchedResultsController{ if (fetchedResultsController != nil) { return fetchedResultsController; } //build the fetch request for Games NSFetchRequest *request = [[NSFetchRequest alloc] init]; NSEntityDescription *entity = [NSEntityDescription entityForName:@"Game" inManagedObjectContext:context]; [request setEntity:entity]; //predicate NSPredicate *predicate = [NSPredicate predicateWithFormat:@"platform == %@", selectedPlatform]; [request setPredicate:predicate]; //sort based on name NSSortDescriptor *sortDescriptor = [[NSSortDescriptor alloc] initWithKey:@"name" ascending:YES]; NSArray *sortDescriptors = [[NSArray alloc] initWithObjects:sortDescriptor, nil]; [request setSortDescriptors:sortDescriptors]; //fetch and build fetched results controller NSFetchedResultsController *aFetchedResultsController = [[NSFetchedResultsController alloc] initWithFetchRequest:request managedObjectContext:context sectionNameKeyPath:nil cacheName:@"Root"]; aFetchedResultsController.delegate = self; self.fetchedResultsController = aFetchedResultsController; [sortDescriptor release]; [sortDescriptors release]; [predicate release]; [request release]; [aFetchedResultsController release]; return fetchedResultsController; } At the end of this method, the fetchedResultsController's _fetch_request - _predicate member is set to an NSComparisonPredicate object. All is well in the world. By the time - (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section gets called, the _predicate is now a Zombie, which will eventually crash the application when the table attempts to update itself. I'm more or less flummoxed. I'm not releasing the fetched results controller or any of it's parts, and the only part getting dealloc'd is the predicate. Any ideas?

  • Tips for using Subversion and XCode in a team project

    - by FelipeUY
    Hi to all. I've been working on an Xcode (iPhone) project with three different persons. We have the project on a Subversion repository, but we still don't completely understand some aspects of the Subversion + Xcode methodology: 1) Each time someone does a commit on a single file, it may appear or not in the project of the other developers. Even though the same person that creates the new files, it adds those files to the Repository and then it commits on those files. Why does that happens? Any suggestions? 2) Each person that is involved on the project can't do a "Commit entire project" without causing a considerable headache to the rest of the developers... any idea how this should be done?. The working methodology that we are trying to implement is that only one developer (generally the leader of the project) can Commit the entire project but he must inform the rest of the team, so everybody can be prepared to receive a message asking him to discard his changes and read the new files from the repository. I need suggestions or advice on how to handle a project with multiple developers using subversion. We have read the Subversion handbook, and many other messages on StackOverflow but I still can't find any useful advice. Thanks for any tip!

    i have posted similar problem here http://stackoverflow.com/questions/2920315/permutation-of-array but i want following we know that with length n there is n! possible permutation from which one such that all element are in order they are in sorted variant so i want break permutation when array is in order and print result but something is wrong i think that problem is repeated of permutation here is my code import java.util.*; public class permut{ public static Random r=new Random(); public static void display(int a[],int n){ for (int i=0;i<n;i++){ System.out.println(a[i]); } } public static void Permut(int a[],int n){ int j=0; int k=0; while (j<fact(n)){ int s=r.nextInt(n); for (int i=0;i<n;i++){ k=a[i]; a[i]=a[s]; a[s]=k; } j++; if (sorted(a,n)) display(a,n); break; } } public static void main(String[]args){ int a[]=new int[]{3,4,1,2}; int n=a.length; Permut(a,n); } public static int fact(int n){ if (n==0 || (n==1) ) return 1; return n*fact(n-1); } public static boolean sorted(int a[],int n ){ boolean flag=false; for (int i=0;i<n-1;i++){ if (a[i]<a[i+1]){ flag=true; } else{ flag=false; } } return flag; } } can anybody help me? result is nothing

  • Specifying a DLL reference

    - by Jesse
    I'm having trouble setting the path to a DLL that is not in the same directory as the executable. I have a reference to dllA.dll. At present, everything is just copied into the same directory and all is well; however, I need to move the executable to another directory while still referencing the DLL in the original directory. So, it's setup like: C:\Original\Dir program.exe dllA.dll dllB.dll dllC.dll But I need to have it setup like: C:\New\Dir program.exe dllB.dll dllC.dl Such that it is still able to reference dllA.dll in C:\Original\dir I tried the following, but to no avail: Set the "Copy Local" value to false for dllA.dll because I want it to be referenced in its original location. Under "Tools Options Projects and Solutions VC++ Directories" I have added the path to "C:\Original\Dir" Added "C:\Original\Dir" to both the PATH and LIB environment variables At runtime, it informs me that it cannot locate dllA.dll Maybe the above steps I took only matter at compile time? I was able to find this http://stackoverflow.com/questions/1382704/c-specifying-a-location-for-dll-reference But I was thinking that my above method should've worked. Any ideas?

  • Is OpenID too complicated?

    - by John Leidegren
    I'm beginning to seriously doubt the OpenID community despite that fact that it works. I'm in the process of currently evaluating OpenID as an authentication service for 'this' site and while the promises are great, I just can't get it to work. And I'm really lost. I ask of the SO community to help me out here. Give me answers and show me examples so I can leverage this in the way it was meant to be. My scenario is very typical. I want to authenticate users through a specific Google Apps domain. If you have access to this Google Apps domain, then you have access to my web application. Where I get lost, is all the prerequisites and dependencies involved. What is XRD? What is Yadis? Why do I need XRD and Yadis? What do I need to do to deploy OpenID authentication on my website? Also, this is really important to me. When I login to SO, I use my Google Account. When I click the login button I'm presented with this confirmation page. Where I'm granting SO the right to use my Google Account credentials. Somehow, Google knows that it's "Stackoverflow.com" that's asking me if it's okay to login. And I wish to know what manner of control I have over this little text. I intend to deploy OpenID on several different domains but I would prefer if they would all work without having to be individually configured with special parameters, such as secret API keys and what not. However, I don't know for sure if this is a prerequisite of OpenID, that or the Federated Login API that Google provides.
