• Why am I getting "(304) Not Modified" error on some links when using HttpWebRequest?

  - by Greg

  Hi, Any ideas why on some links that I try to access using HttpWebRequest I am getting "The remote server returned an error: (304) Not Modified." in the code? The code I'm using is from Jeff's post here. Note the concept of the code is a simple proxy server, so I'm pointing my browser at this locally running piece of code, which gets my browsers request, and then proxies it on by creating a new HttpWebRequest, as you'll see in the code. It works great for most sites/links, but for some this error comes up. You will see one key bit in the code is where it seems to copy the http header settings from the browser request to it's request out to the site, and it copies in the header attributes. Not sure if the issue is something to do with how it mimics this aspect of the request and then what happens as the result comes back? case "If-Modified-Since": request.IfModifiedSince = DateTime.Parse(listenerContext.Request.Headers[key]); break; I get the issue for example from http://en.wikipedia.org/wiki/Main_Page thanks

• Improving Performance on this Image Creation function

  - by Abs

  Hello all, I am making use of GD2 and the image functions to take in a string and then convert that into an image using different fonts at different sizes. The function I use is below. Currently, its pretty quick but not quick enough. The function gets called about 20 times per user and the images generated are always new ones (different) so caching isn't going to help! I was hoping to get some ideas on how to make this function faster. Maybe supply more RAM to the script running? Anything else that is specific to this PHP function? Anything else that I can do to tweak performance of this function? function generate_image($save_path, $text, $font_path, $font_size){ $font = $font_path; /* * I have simplifed the line below, its actually a function that works out the size of the box * that is need for each image as the image size is different based on font type, font size etc */ $measure = array('width' => 300, 'height'=> 120); if($measure['width'] > 900){ $measure['width'] = 900; } $im = imagecreatetruecolor($measure['width'], $measure['height']); $white = imagecolorallocate($im, 255, 255, 255); $black = imagecolorallocate($im, 0, 0, 0); imagefilledrectangle($im, 0, 0, $measure['width'], $measure['height'], $white); imagettftext($im, $font_size, 0, $measure['left'], $measure['top'], $black, $font, ' '.$text); if(imagepng($im, $save_path)){ $status = true; }else{ $status = false; } imagedestroy($im); return $status; } Thanks all for any help

• Apache module, is it possible to have asynchronous processing

  - by prashant2361

  Hi, I have a requirement where I need to send continous updates to my clients. Client is browser in this case. We have some data which updates every sec, so once client connects to our server, we maintain a persistent connection and keep pushing data to the client. I am looking for suggestions of this implementation at the server end. Basically what I need is this: 1. client connects to server. I maintain the socket and metadata about the socket. metadata contains what updates need to be send to this client 2. server process now waits for new client connections 3. One other process will have the list of all the sockets opened and will go through each of them and send the updates if required. Can we do something like this in apache module: 1. apache process gets the new connection. It maintains the state for the connection. It keeps the state in some global memory and returns back to root process to signify that it is done so that it can accept the new connection 2. the apache process though has returned the status to root process but it is also executing parallely where it going through its global store and sending updates to the client, if any. So can a apache process do these things: 1. Have more than one connection associated with it 2. Asynchronously waiting for new connection and at the same time processing the previous connections?

• New to Android: Dynamically changing views

  - by Josiah Kiehl

  I'm trying to learn how to build apps for Android. The first simple app, which will become a component of a bigger app I hope to build, is to have a button on the screen where, when tapped, it adds something new to the view. For instance: Imagine a layout that only has a button: [Create!] When that button, the view gets a new row added to it: [Create!] A Something! Upon subsequent presses, more rows are added [Create!] A Something! A Something! And so on. I've made a LinearLayout and placed the button in it, and have attached a click listener to it. That all works great. What I can't figure out is how to get a handle on the LinearLayout in the onClick function with which I'll addView() the new TextView that says "A Something!" Am I on the right track? What basic thing am I missing? Thanks!

• How do you make a static sprite be a child of another sprite in cocos2D while using SpaceManager

  - by JJBigThoughts

  I have two static (STATIC_MASS) SpaceManager sprites. One is a child of the other - by which I mean that one sort of builds up the other one, but although the child's images shows up in the right place, the child doesn't seem to exists in the chipmunk physics engine, like I would expect. In my case, I have a backboard (rectangular sprite) and a hoop (a circular sprite). Since I might want to move the backboard, I'd like to attach the hoop to backboard so that the hoop automatically moves right along with the backboard. Here, we see a rotating backboard with attached hoop. It looks OK on the screen, but other objects only bounce off the backboard but pass right through the hoop (in a bad sense of the term). What doesn't my child sprite seem to exist in the physics engine? // Add Backboard cpShape *shapeRect = [smgr addRectAt:cpvWinCenter mass:STATIC_MASS width:200 height:10 rotation:0.0f ];// We're upgrading this cpCCSprite * cccrsRect = [cpCCSprite spriteWithShape:shapeRect file:@"rect_200x10.png"]; [self addChild:cccrsRect]; // Spin the static backboard: http://stackoverflow.com/questions/2691589/how-do-you-make-a-sprite-rotate-in-cocos2d-while-using-spacemanager // Make static object update moves in chipmunk // Since Backboard is static, and since we're going to move it, it needs to know about spacemanager so its position gets updated inside chipmunk. // Setting this would make the smgr recalculate all static shapes positions every step // cccrsRect.integrationDt = smgr.constantDt; // cccrsRect.spaceManager = smgr; // Alternative method: smgr.rehashStaticEveryStep = YES; smgr.rehashStaticEveryStep = YES; // Spin the backboard [cccrsRect runAction:[CCRepeatForever actionWithAction: [CCSequence actions: [CCRotateTo actionWithDuration:2 angle:180], [CCRotateTo actionWithDuration:2 angle:360], nil] ]]; // Add the hoop cpShape *shapeHoop = [smgr addCircleAt:ccp(100,-45) mass:STATIC_MASS radius: 50 ]; cpCCSprite * cccrsHoop = [cpCCSprite spriteWithShape:shapeHoop file:@"hoop_100x100.png"]; [cccrsRect addChild:cccrsHoop]; This is only half working for me. Note: SpaceManager is a toolkit for working with cocos2D-iphone

• Transitioning from FlexBuilder 3 to FlashBuilder 4 ... there and back again.

  - by Robusto

  It's growing pains time again. Some of our stuff requires FlashBuilder 4 and some still requires FlexBuilder 3. Both are installed OK, and no projects use both IDEs. The trouble is, when I go back to work on a FlexBuilder 3 project it takes freakin' forever to build and I get weird errors like these: This doesn't seem to cause any identifiable problems except to throw up a modal dialog at various points in the build process, forcing user interaction. But I do notice that memory fills up fast in FB3 and generally FB3 starts behaving strangely and ultimately quits once it gets up over 700MB. This is only a temporary bridge situation until we get all projects into FB4, but "temporary" could mean weeks if not months. Does anyone have any advice for how to get through this bridge period? Is there anything I can do to make these two IDEs work and play well together? Failing that, does anyone know what "java.lang.String" is the "reason" for the problem? Does Eclipse have a resource bundle somewhere that is getting corrupted when i go back and forth between the two?

• Programmatically controlled virtual drive

  - by Robert Lin

  How would I go about creating a virtual drive with which I can programmatically and dynamically change the contents? For instance, program A starts running and creates a virtual drive. When program B looks in the drive, it sees an error log and starts reading/processing it. In the middle of all this program A gets a signal from somewhere and decides to add to the log. I want program B to be unaware of the change and just keep on going. Program B should continue reading as if nothing happened. Program A would just report a rediculously large file size for the log and then fill it in as appropriate. Program A would fill the log with tags if program B tries to read past the last entry. I know this is a weird request but there's really no other way to do this... I basically can't rewrite program B so I need to fool it. How do I do this in windows? How about OSX?

• C# StackOverflowException

  - by KSwift87

  Problem: I am trying to update a List. If a certain item's ID already exists in the List, I want to add onto that item's quantity. If not, then I want to add another item to the list. cart = (List<OrderItem>)Session["cart"]; for(int counter = cart.Count-1; counter >= 0; counter--) { if (cart[counter].productId == item.productId) { cart[counter].productQuantity += item.productQuantity; } else if (counter == 0) { cart.Add(item); } } "cart[counter]" and "item" represent an instance(s) of a custom object of mine. Currently when I finally find a matching ID, everything APPEARS as though it should work, but I get a StackOverflowException thrown in my custom object class. public int productQuantity { get { return _productQuantity; } set { productQuantity = value; } } It gets thrown right at the open-bracket of the "set". Could somebody please tell me what the heck is wrong because I've been going at this for the past 2+ hours to no avail. Thank you in advance.

• $.ajax not loading data data everytime from server

  - by Ted

  I have written a simple jQuery.ajax function which loads a user control from the server on click of a button. The first time I click the button, it goes to the server and gets me the user control. But each subsequent click of the same button does not goes to the server to fetch me the user control. Since my user control fetches data from db, I need to reload the user control everytime i hit the button. But if anyhow I get my user control to unload from the page, and re-click the button, it goes to the server and fetches me the user control. Here's the code: $("#btnLoad").click(function() { if ($(this).attr("value") == "Load Control") { $.ajax({ url: "AJAXHandler.ashx", data: { "lt": "loadcontrol" }, dataType: "html", success: function(data) { content.html(data); } }); $(this).attr("value", "Unload Control"); } else { $.ajax({ url: "AJAXHandler.ashx", data: { "lt": "unloadcontrol" }, dataType: "html", success: function(data) { content.html(data); } }); $(this).attr("value", "Load Control"); } }); Please let me know if there is any other way I can get my user control loaded from server everytime I click the button.

• Readonly SiteMapNodes in ASP.Net MVC?

  - by BenN

  I'm using MVCSiteMap as a SiteMapProvider for my MVC site. I have a node set up like so.... <mvcSiteMapNode key="1" title="Product" controller="Product" action="Display" isDynamic="true" dynamicParameters="id"> <mvcSiteMapNode key="11" title="More Details" controller="Product" action="MoreDetails" isDynamic="true" dynamicParameters="id" /> </mvcSiteMapNode> ...Which means I can go to ~/Product/Display/12 and get a correct sitemap node for product id 12 (in this case just Product. And I can go to ~/Product/MoreDetails/12 and get the sitemap path for the MoreDetails (Product - More Details). The problem is that the link back to Product in this sitemap doesn't work - it skips the id off the end, instead linking to ~/Product/Display/. Which sucks. I've discovered I can edit the Title of a node using SiteMap.CurrentNode.Title = "My New Title"; But... SiteMap.CurrentNode.ParentNode.Url = "http://www.google.com"; Doesn't set the Url for the parent node; it gets the default link described before. Any ideas how I can set the URL of a SiteMapNode?

• Facebook Open Graph - post to all approved users feeds.

  - by simnom

  Hi, I'm struggling to get to grips with posting a feed item to all the members of an approved application. Within the application settings for the user it is stating that the application has permission to post to the wall but I can only achieve this if that user is currently logged in to facebook. Obviously I would like this to function so that any items I uploaded are posted to all the members of the application at any one time. I am using the Facebook PHP SDK from http://github.com/facebook/php-sdk/ and currrently my code is as follows: require 'src/facebook.php'; //Generates access token for this transaction $accessToken = file_get_contents("https://graph.facebook.com/oauth/access_token?type=client_cred&client_id=MyAppId&client_secret=MySecret"); //Gets the full user details as an object $contents = json_decode(file_get_contents("https://graph.facebook.com/SomeUserId?scope=publish_stream&" . $accessToken)); print_r($contents); if ($facebook->api('/' . $contents->id . '/feed', 'POST', array( 'title' => 'New and Improved, etc - 12/03/2010', 'link' => 'http://www.ib3.co.uk/news/2010/03/12/new-and-improved--etc', 'picture' => 'http://www.ib3.co.uk/userfiles/image/etc-booking.jpg', 'scope' => 'publish_stream' ) )==TRUE) { echo "message posted"; } else { echo "message failed"; } The output from $contents shows the expected user details but nothing relating to the permissions for my application. Am I missing a trick here? Then using the $facebook-api() function I am receiving a #200 - Permissions error. The application does not have permission to perform this action. This is driving me a little potty as I suspect I'm missing something straightforward with the authorisation but what? Many thanks in advance for an assistance offered.

• Update "Properties" model when adding a new record in CakePHP

  - by Paul Willy

  Hi, I'm writing an application in CakePHP that, for now, is to be used to make quotes for customers. So Quote is a model. I want to have a separate model/table for something like "Property," which may be used by other models. Each time a user gets to the "Add Quote" action, I basically want to pull a Property called "nextQuoteNumber" or something along those lines, and then automatically increment that property, even if the new Quote isn't saved. So I don't think just using an autoincrement for Quote's id is appropriate here - also, the "quote number" could be different from the row's id. I know this is simple enough to do, but I'm trying to figure out the "proper" CakePHP way of doing it! I'm thinking that I should have a method inside the Property model, say "getProperty($property_name)", which would pull the value to return, and also increment the value... but I'm not sure what the best way of doing that is, or how to invoke this method from the Quotes controller. What should I do? Thanks in advance!

• Redirect uploaded files to another server, using nginx

  - by Serg ikS

  I am creating a web service of scheduled posts to some soc. network.Need help dealing with file uploads under high traffic. Process overview: User uploads files to SomeServer (not mine). SomeServer then responds with a JSON string. My web app should store that JSON response. Opt. 1 — Save, cURL POST, delete tmp The stupid way I made it work: User uploads files to MyWebApp; MyWebApp cURL's the file further to SomeServer, getting the response. Opt.2 — JS magic The smart way it could be perfect: User uploads the file directly to SomeServer, from within an iFrame; MyWebApp gets the response through JavaScript. But this is(?) impossible due to the 'Same Origin Policy', isn't it? Opt. 3 — nginx proxying? The better way for a production server: User uploads files to MyWebApp; nginx intercepts the file uploads and sends them directly to the SomeServer; JSON response is also intercepted by nginx and processed by MyWebApp. Does this make any sense, and what would be the nginx config for, say, /fileupload Location to proxy it to SomeServer ?

• How to use IsKeyboardFocusWithin and IsSelected together?

  - by jpsstavares

  I have a style defined for my ListBoxItems with a trigger to set a background color when IsSelected is True: <Style x:Key="StepItemStyle" TargetType="{x:Type ListBoxItem}"> <Setter Property="SnapsToDevicePixels" Value="true"/> <Setter Property="OverridesDefaultStyle" Value="true"/> <Setter Property="Template"> <Setter.Value> <ControlTemplate TargetType="ListBoxItem"> <Border Name="Border" Padding="0" SnapsToDevicePixels="true"> <ContentPresenter /> </Border> <ControlTemplate.Triggers> <Trigger Property="IsSelected" Value="True"> <Setter TargetName="Border" Property="Background" Value="#40a0f5ff"/> </Trigger> </ControlTemplate.Triggers> </ControlTemplate> </Setter.Value> </Setter> </Style> This style maintains the selected item even when the ListBox and ListBoxItem loses focus, which in my case is an absolute must. The problem is that I also want the ListBoxItem to be selected when one of its TextBox's child gets focused. To achieve this I add a trigger that sets IsSelected to true when IsKeyboardFocusWithin is true: <Trigger Property="IsKeyboardFocusWithin" Value="True"> <Setter Property="IsSelected" Value="True" /> </Trigger> When I add this trigger the Item is selected when the focus is on a child TextBox, but the first behaviour disappears. Now when I click outside the ListBox, the item is de-selected. How can I keep both behaviours?

• Building Paypal based membership website - total noob - would appreciate help

  - by Ali

  this is a follow up on my question on paypal integration. I'm working ona membership site for racing fans. My membership site has 3 membership levels - free, gold and premium. When a user signs up he/she can gets a free membership on the spot but has the option to upgrade to a gold membership for 4 Dollars a month or a premium membership for 10 Dollars a month. I've gone through the paypal integration guide a few times though and have a vague understanding of how to get this to work. I think the recurring payments option would be fine enough - however I don't know how do I implement this in my system. Like when a user decides to go for a paid account i.e. Gold or premium from basic - what should I do on both my code side and on the paypal account side - I'd really appreciate if anyone would outline what I'd have to do here. Plus when a user decides to upgrade from lets say a Gold to a premium account - there is the issue of computing how much should be charged to upgrade his/her account eg: a user has been billed for 4 dollars and the next day opts to go for a premium account so assuming that the surplus for the rest of the month is 5 dollars and further from that all payments would be recurring 10 dollars monthly - how do I implement this? And in case a user decides to downgrade from a premium account of 10 dollars a month to a gold account of 4 dollars a month - how do I handle the surplus which would have to be refunded for that month alone and changing the membership? And like wise if someone wishes to cancel membership and go to having a free account - how do I refund whatever is owed and cancel the subscription. I'm sorry if it sounds like I'm asking to be spoon fed :( I'm quite new to this and this is for a client and I would really appreciate all the help here and really have to get this working right. Thanks again everyone - waiting for all your replies.

• Zipping with padding in Haskell

  - by Travis Brown

  A couple of times I've found myself wanting a zip in Haskell that adds padding to the shorter list instead of truncating the longer one. This is easy enough to write. (Monoid works for me here, but you could also just pass in the elements that you want to use for padding.) zipPad :: (Monoid a, Monoid b) => [a] -> [b] -> [(a, b)] zipPad xs [] = zip xs (repeat mempty) zipPad [] ys = zip (repeat mempty) ys zipPad (x:xs) (y:ys) = (x, y) : zipPad xs ys This approach gets ugly when trying to define zipPad3. I typed up the following and then realized that of course it doesn't work: zipPad3 :: (Monoid a, Monoid b, Monoid c) => [a] -> [b] -> [c] -> [(a, b, c)] zipPad3 xs [] [] = zip3 xs (repeat mempty) (repeat mempty) zipPad3 [] ys [] = zip3 (repeat mempty) ys (repeat mempty) zipPad3 [] [] zs = zip3 (repeat mempty) (repeat mempty) zs zipPad3 xs ys [] = zip3 xs ys (repeat mempty) zipPad3 xs [] zs = zip3 xs (repeat mempty) zs zipPad3 [] ys zs = zip3 (repeat mempty) ys zs zipPad3 (x:xs) (y:ys) (z:zs) = (x, y, z) : zipPad3 xs ys zs At this point I cheated and just used length to pick the longest list and pad the others. Am I overlooking a more elegant way to do this, or is something like zipPad3 already defined somewhere?

• Unable to change URL for .NET reference to dynamic web service

  - by Malvineous

  Hi all, I have a web reference added to a C# .NET project. The URL for the web reference needs to change depending on whether I'm building for a development, staging or production environment. I've set the web service to be dynamic, which supposedly means it takes the URL from my app.config file. When I perform a build it overwrites the app.config with the required file which contains the correct URL (different file for each of dev/staging/production.) I then go into the solution properties and make sure the Settings.settings file is updated with the app.config changes. However when I view the properties for the web service, it is still showing the old URL, despite it being dynamic, and supposed to be reading from my settings file (even after closing and reopening the project/solution.) The app.config and the settings file all have the new URL, but the web reference doesn't notice it has changed. If I do a build it ignores the URL in the settings file and tries to connect to the last URL manually typed into the web reference's properties. Typing a URL into these properties correctly updates the app.config and .settings files, so the link is definitely there. I'm a bit new to .NET but it seems to me the purpose of setting the service to be dynamic is so that you can change the URL elsewhere, but when I do this it just gets ignored! Am I doing something wrong?

• NSTask executed only once

  - by Eimantas

  I'm having trouble executing different NSTask's. Same launchPath, different arguments. I have a class who's instances administer own NSTask objects and depending on arguments those instances were initialized with - dependent NSTask object is being created. I have two initializers: // Method for finished task - (void)taskFinished:(NSNotification *)aNotification { [myTask release]; myTask = nil; [self createTask]; } // Designated initializer - (id) init { self = [super init]; if (self != nil) { [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(taskFinished:) name:NSTaskDidTerminateNotification object:nil]; [self createTask]; } return self; } // Convenience initializer - (id)initWithCommand:(NSString *)subCommand { self = [self init]; if (self) { [self setCommand:subCommand]; } return self; } And here 's the createTask method: - (void)createTask { // myTask is a property defined as NSTask* myTask = [[NSTask alloc] init]; [myTask setLaunchPath:@"/usr/bin/executable"]; } Say I have 3 buttons. Each one creates different class instance with different NSTask objects. But problem is that only first one gets executed. The second ones does not even triger "click" event (via target-action). I think it could be cause of launchPath I'm trying to use, 'cause simple /bin/ls works fine. The same command in terminal has 0 return value (i.e. all is fine). Any guides or gotchas are much appreciated.

• How to make Web Storage persistent in Cordova using JS?

  - by ett

  I have a small quiz app, which is a cross-platform mobile app, that I plan for it to run on Android, iOS, and WP8. I want to store a local highscore, where it will keep track how many points the user had, and if he/she does better than the already stored highscore, update the current highscore. Though, I want the highscore to be persistent, what I mean is, every time the user opens the app I want the last highscore to be present and it to be compared with the new quiz score. Meaning, I don't want the highscore to be deleted after each time the app is closed. I also want for the first time when the app is ran, the highscore to be set to 0, so obviously the first time the user finishes the quiz gets a new highscore. I have those codes so far: scoredb.js // Wait for device API libraries to load document.addEventListener("deviceready", initScoreDB, false); // Device APIs are available function initScoreDB() { window.localStorage.setItem("score", 0); highscore = window.localStorage.getItem("score"); } main.js var correct = 0; var highscore; // In between I have some code that keeps incrementing // correct variable for each correct answer. if (correct > highscore) { window.localStorage.setItem("score", correct); highscore = correct; } It does seem to work okay once the app is started. I did the quiz three times, in the simulator, and it keeps the score as it should. Though, each time I open the app, highscore is reseted to 0. I guess it is due to the fact that I call initScoreDB when the device is ready, and I initialize the score to 0 there and give that value to highscore. Can someone help me to initialize the score to 0 only when the app is ran for the first time, and all the other times to keep the latest highscore as the current highscore and compare it each time with the score that is achieved when the quiz is finished. If someone can help me, I would be glad.

• Function parameters evaluation order: is undefined behaviour if we pass reference?

  - by bolov

  This is undefined behaviour: void feedMeValue(int x, int a) { cout << x << " " << a << endl; } int main() { int a = 2; int &ra = a; feedMeValue(ra = 3, a); return 0; } because depending on what parameter gets evaluated first we could call (3, 2) or (3, 3). However this: void feedMeReference(int x, int const &ref) { cout << x << " " << ref << endl; } int main() { int a = 2; int &ra = a; feedMeReference(ra = 3, a); return 0; } will always output 3 3 since the second parameter is a reference and all parameters have been evaluated before the function call, so even if the second parameter is evaluated before of after ra = 3, the function received a reference to a wich will have a value of 2 or 3 at the time of the evaluation, but will always have the value 3 at the time of the function call. Is the second example UB? It is important to know because the compiler is free to do anything if he detects undefined behaviour, even if I know it would always yield the same results. *Note: I think that feedMeReference(a = 3, a) is the exact same situation as feedMeReference(ra = 3, a). However it seems not everybody agrees, in the addition to having 2 completely different answers.

• UTF8 charset, diacritical elements, conversion problems - and Zend Framework form escaping

  - by imanc

  Hey, I am writing a webapp in ZF and am having serious issues with UTF8. It's using multi lingual content through Zend Form and it seems that ZF heavily escapes all of these characters and basically just won't show a field if there's diacritical elements 'é' and if I use the HTML entity equivalent e.g. é it gets escaped so that the user will see 'é'. Zend Form allows for having non escaped data, but trying to use this is confusing, and it seems it'd need to be used all over the place. So, I have been told that if the page and the text is in UTF8, no conversion to htmlentities is required. Is this true? And if the last question is true, then how do I convert the source text to UTF8? I am comfortable setting up apache so that it sends a default UTF8 charset heading, and also adding the charset meta tag to the html, but doing this I am still getting messed up encoding. I have also tried opening the translation csv file in TextWrangler on OSX as UTF8, but it has done nothing. Thanks! L

• How to determine Scale of Line Graph based on Pixels/Height?

  - by Dexter

  I have a problem due to my terrible math abilities, that I cannot figure out how to scale a graph based on the maximum and minimum values so that the whole graph will fit onto the graph-area (400x420) without parts of it being off the screen (based on a given equation by user). Let's say I have this code, and it automatically draws squares and then the line graph based on these values. What is the formula (what do I multiply) to scale it so that it fits into the small graphing area? vector<int> m_x; vector<int> m_y; // gets automatically filled by user equation or values int HeightInPixels = 420;// Graphing area size!! int WidthInPixels = 400; int best_max_y = GetMaxOfVector(m_y); int best_min_y = GetMinOfVector(m_y); m_row = 0; m_col = 0; y_magnitude = (HeightInPixels/(best_max_y+best_min_y)); // probably won't work magnitude = (WidthInPixels/(int)m_x.size()); m_col = m_row = best_max_y; // number of vertical/horizontal lines to draw ////x_magnitude = (WidthInPixels/(int)m_x.size())/2; Doesn't work well ////y_magnitude = (HeightInPixels/(int)m_y.size())/2; Doesn't work well ready = true; // we have values, graph it Invalidate(); // uses WM_PAINT

• Using git filter-branch to remove commits by their commit message

  - by machineghost

  In our repository we have a convention where every commit message starts with a certain pattern: Redmine #555: SOME_MESSAGE We also do a bit of rebasing to bring in the potential release branch's changes to a specific issue's branch. In other words, I might have branch "foo-555", but before I merge it in to branch "pre-release" I need to get any commits that pre-release has that foo-555 doesn't (so that foo-555 can fast-forward merge in to pre-release). However, because pre-release sometimes changes, we sometimes wind up with situations where you bring in a commit from pre-release, but then that commit later gets removed from pre-release. It's easy to identify commits that came from pre-release, because the number from their commit message won't match the branch number; for instance, if I see "Redmine #123: ..." in my foo-555 branch, I know that its not a commit from my branch. So now the question: I'd like to remove all of the commits that "don't belong" to a branch; in other words, any commit that: Is in my foo-555 branch, but not in the pre-release branch (pre-release..foo-555) Has a commit message that doesn't start with "Redmine #555" but of course "555" will vary from branch to branch. Is there any way to use filter-branch (or any other tool) to accomplish this? Currently the only way I can see to do it is to do go an interactive rebase ("git rebase -i") and manually remove all the "bad" commits.

• Fun with "The remote server returned an error: NotFound" - Silverlight4 Out of Browser

  - by Scott Silvi

  Hey all - I'm running SL4 on VS2010. I've got an app that authenticates via a web service to SPROC in my db. Unfortunately this is not WCF/WCF RIA, as I'm inheriting the DB/services from my client. This works perfectly inside of a browser. I'm attempting to move this OOB, and it's at this point that my authentication fails. Here's the steps I took... 1) SL App Properties Enable running app Out of Browser 2) SL App Properties Out of Browser Settings Require elevated trust when running OOB If i set a breakpoint on my logon button click, I see the service call is being made. However, if I step through it (or set a breakpoint on the actual logon web service), the code never gets that far. Here's the block it fails on: public LogonSVC.LogonResponse EndLogon(System.IAsyncResult result) { object[] _args = new object[0]; LogonSVC.LogonResponse _result = ((LogonSVC.LogonResponse)(base.EndInvoke("Logon", _args, result))); return _result; } I know using Elevated Trust means the crossdomain.xml isn't necessary. I dropped one in that allows everything, just to test, and that still fails. here's the code that calls the service: private void loginButton_Click(object sender, RoutedEventArgs e) { string Username = txtUserName.Text; string Password = txtPassword.Password; Uri iSilverlightServiceUriRelative = new Uri(App.Current.Host.Source, "../Services/Logon.asmx"); EndpointAddress iSilverlightServiceEndpoint = new EndpointAddress(iSilverlightServiceUriRelative); BasicHttpBinding iSilverlightServiceBinding = new BasicHttpBinding(BasicHttpSecurityMode.Transport);// Transport if it's HTTPS:// LogonService = new LogonSVC.LogonSoapClient(iSilverlightServiceBinding, iSilverlightServiceEndpoint); LogonService.LogonCompleted += new EventHandler<LogonSVC.LogonCompletedEventArgs>(LogonService_LogonCompleted); LogonService.LogonAsync(Username, Password); } My LogonService_LogonCompleted doesn't fire either (which makes sense, just a heads up). I don't know how to fiddler this, as this is running OOB with the site served via localhost/IIS. I know this works though in browser, so I'm curious what would break it OOB. Thank you, Scott

• How to create custom omniauth provider (how to return data)

  - by user2803917

  I searched all around the net, how to create a custom provider for omniauth.. and i succedded partly.. I created a gem, and it worked perfectly, except the part, that i cant understand how to return the gathered data to sessions controller, like other providers do.. here is the code in auth gem: require 'multi_json' require 'digest/md5' require 'rest-client' module OmniAuth module Strategies class Providername < OmniAuth::Strategies::OAuth attr_accessor :app_id, :api_key, :auth def initialize(app, app_id = nil, api_key = nil, options = {}) super(app, :providername) @app_id = app_id @api_key = api_key end protected def request_phase redirect "http://valid_url" end def callback_phase if request.params['code'] && request.params['status'] == 'ok' response = RestClient.get("http://valid_url2/?code=#{request.params['auth_code']}") auth = MultiJson.decode(response.to_s) unless auth['error'] @auth_data = auth if @auth_data @return_data = OmniAuth::Utils.deep_merge(super, { 'uid' => @auth_data['uid'], 'nickname' => @auth_data['nick'], 'user_info' => { 'first_name' => @auth_data['name'], 'last_name' => @auth_data['surname'], 'location' => @auth_data['place'], }, 'credentials' => { 'apikey' => @auth_data['apikey'] }, 'extra' => {'user_hash' => @auth_data} }) end end else fail!(:invalid_request) end rescue Exception => e fail!(:invalid_response, e) end end end end and here i call it in my initializers: Rails.application.config.middleware.use OmniAuth::Builder do provider "providername", Settings.providers.providername.app_id, Settings.providers.providername.app_secret end in this code, everything works fine so far, the provider gets called, i get the info from provider, i create a hash (@auth_data) with info, but how do i return it
