  • My Blog is marked as spam because of adBrite

    - by Thala
    I was blogging for over a month. I never thought of publishing ads in my blog until I was recommended to adBrite. I copied the widget code and just added it to my blog. Crap, suddenly I got a message that I was stopped from blogging because it is marked as spam. I never gave up my try, I just kept on sending request to retrieve my blog. How do I get my blogger blog unlocked and not considered spam?

  • Find angle for projectile to meet target in parabolic arc

    - by TheBroodian
    I'm making a thing that launches projectiles in 2D. Its projectiles are fired with a set initial velocity, and are only affected by gravity. Assuming that its target is within range, and that there aren't any obstacles, how would my thing find the appropriate angle at which to launch its projectile (in radians)? The equation for this is found here: Wikipedia: Angle Required to Hit Coordinate Sadly, I'm not a physicist (a.k.a. can't read smart people math) and am having a hard time reading its breakdown. If not only for the sake of anybody else that might read this other than myself, would anybody be kind enough to break the equation down into baby words please?

  • Deferred contexts and inheriting state from the immediate context

    - by dreijer
    I took my first stab at using deferred contexts in DirectX 11 today. Basically, I created my deferred context using CreateDeferredContext() and then drew a simple triangle strip with it. Early on in my test application, I call OMSetRenderTargets() on the immediate context in order to render to the swap chain's back buffer. Now, after having read the documentation on MSDN about deferred contexts, I assumed that calling ExecuteCommandList() on the immediate context would execute all of the deferred commands as "an extension" to the commands that had already been executed on the immediate context, i.e. the triangle strip I rendered in the deferred context would be rendered to the swap chain's back buffer. That didn't seem to be the case, however. Instead, I had to manually pull out the immediate context's render target (using OMGetRenderTargets()) and then set it on the deferred context with OMSetRenderTargets(). Am I doing something wrong or is that the way deferred contexts work?

  • Setting density for Android game

    - by Asghar
    I am developing an Android game, in which a ball (bitmap) translates( is in motion). So I have provided motion equations for the ball. I have checked my app on Samsung galaxy S2 whose actual density is roundly 252 dpi, and It works fine on that. So my question is that Does these motions of bitmaps in surfaceView, depends on actual density of phone( i.e 252 dpi for S2) or generalized density(i.e 240 dpi). I am confused whether if I run this app on 235 dpi smartphone, So will it have the same performance of motion as it is on Galaxy S2( with 252 dpi) or it would be little slow ? Any help will be appreciated.

  • Box2d too much for Circle/Circle collision detection?

    - by Joey Green
    I'm using cocos2d to program a game and am using box2d for collision detection. Everything in my game is a circle and for some reason I'm having a problem with some times things are not being detected as a collision when they should be. I'm thinking of rolling up my own collision detection since I don't think it would be too hard. Questions are: Would this approach work for collision detection between circles? a. get radius of circle A and circle B. b. get distance of the center of circle A and circle B c. if the distance is greater than or equal to the sum of circle A radius and circle B radius then we have a hit Should box2d be used for such simple collision detection? There are no physics in this game.

  • How can I set the rotation of a shape to the same as my image?

    - by BleedObsidian
    The way you set rotations of images is different from setting shape rotations. So how can I make the shape have the same rotation as my image? This is how my image rotates: if(input.isKeyDown(Input.KEY_RIGHT)) { rotate += rotateSpeed * delta; image.rotate(rotate - image.getRotation()); } How can I get the same effect but with a shape? For example: How can I get that rectangle to be at the same rotation as the car?

  • Getting this error in rails: `ActionView::Template::Error (code converter not found (UTF-8 to UTF-16))`

    - by Victor S
    I've started getting the following error in one of my views for some reason, I don't get it in development, but only in production. Here is a snippet of the backtrace, any ideas? ActionView::Template::Error (code converter not found (UTF-8 to UTF-16)): 19: [title, summary.gsub(/^/, " "), nil].join("\n\n") 20: end 21: end.join 22: sections = sections.force_encoding('UTF-8').encode('UTF-16', :invalid => :replace).encode('UTF-8') if sections.respond_to?(:force_encoding) 23: %> 24: 25: <%= raw sections %>

  • Rails dealing with blank params at controller level

    - by stephenmurdoch
    I have a User model: class User < ActiveRecord::Base has_secure_password # validation lets users update accounts without entering password validates :password, presence: { on: :create }, allow_blank: { on: :update } validates :password_confirmation, presence: { if: :password_digest_changed? } end I also have a password_reset_controller: def update # this is emailed to the user by the create action - not shown @user=User.find_by_password_reset_token!(params[:id]) if @user.update_attributes(params[:user]) # user is signed in if password and confirmation pass validations sign_in @user redirect_to root_url, :notice => "Password has been reset." else flash.now[:error] = "Something went wrong, please try again." render :edit end end Can you see the problem here? A user can submit a blank a password/confirmation and rails will sign them in, because the User model allows blank on update. It's not a security concern, since an attacker would still need access to a user's email account before they could get anywhere near this action, but my problem is that a user submitting 6 blank chars would be signed in, and their password would not be changed for them, which could lead to confusion later on. So, I've come up with the following solution, and I'd like to check if there's a better way of doing it, before I push to production: def update @user=User.find_by_password_reset_token!(params[:id]) # if user submits blank password, add an error, and render edit action if params[:user][:password].blank? @user.errors.add(:password_digest, "can't be blank.") render :edit elsif @user.update_attributes(params[:user]) sign_in @user redirect_to root_url, :notice => "Password has been reset." else flash.now[:error] = "Something went wrong, please try again." render :edit end end Should I be checking for nil as well as blank? Are there any rails patterns or idiomatic ruby techniques for solving this? [Fwiw, I've got required: true on the html inputs, but want this handled server side too.]

  • Raphaeljs animation kills my browser

    - by user1688606
    I have this code where I have a made a character using 20 paths and put it into a set. Now when I animate the set, the first transformation runs smoothly, the second animation stutters, the third animation doesn't happen as it should and the 4th animation kills my pc, the browser hangs and in the task manager I can see that it consumes up to 70% of CPU. How can I avoid this and free the resources so all the animations run smoothly. *I have to execute 10 simple y-axis transformation animations on that character. JS Fiddle window.onload = function(){ var paper = Raphael(0,0,400,400); var character = paper.set(); paper.setStart(); var attr = {fill:'red',stroke:'none'}; var shape = paper.rect(100,100,10,20).attr(attr); var shape = paper.rect(100,100,10,20).attr(attr); var shape = paper.rect(100,100,10,20).attr(attr); var shape = paper.rect(100,100,10,20).attr(attr); var shape = paper.rect(100,100,10,20).attr(attr); var shape = paper.rect(100,100,10,20).attr(attr); var shape = paper.rect(100,100,10,20).attr(attr); var shape = paper.rect(100,100,10,20).attr(attr); var shape = paper.rect(100,100,10,20).attr(attr); var shape = paper.rect(100,100,10,20).attr(attr); var shape = paper.rect(100,100,10,20).attr(attr); var shape = paper.rect(100,100,10,20).attr(attr); var shape = paper.rect(100,100,10,20).attr(attr); var shape = paper.rect(100,100,10,20).attr(attr); var shape = paper.rect(100,100,10,20).attr(attr); var shape = paper.rect(100,100,10,20).attr(attr); var shape = paper.rect(100,100,10,20).attr(attr); var shape = paper.rect(100,100,10,20).attr(attr); var shape = paper.rect(100,100,10,20).attr(attr); var shape = paper.rect(100,100,10,20).attr(attr); var character = paper.setFinish(); character.transform("t0,200") //1st animation.. var chartrnsfrm = Raphael.animation({ transform:'...t0,-48' },1000,"easeout",function(){ character.animate(chartrnsfrm1.delay(2000)) }); character.animate(chartrnsfrm.delay(2000)); //2nd animation.. var chartrnsfrm1 = Raphael.animation({ transform:'...t0,-48' },1000,"easeout",function(){ character.animate(chartrnsfrm2.delay(2000)) }); //3rd animation.. var chartrnsfrm2 = Raphael.animation({ transform:'...t0,-48' },1000,"easeout",function(){ character.animate(chartrnsfrm3.delay(2000)) }); //4th animation.. var chartrnsfrm3 = Raphael.animation({ transform:'...t0,-48' },1000,"easeout"); }

  • Why can't I view a directory in Linux?

    - by Thread7
    I am setting up a Linux web server running apache. I uploaded and untared my web sites files. The files in the main directory are all visible when I am SSH'd into the system. However, I am blocked from all subdirectories. If I write: # cd images Then I get the error: -bash: cd: images: Permission denied I am signed in as ec2-user. I untarred the stuff as ec2-user and I doubt there was any permissions in the tar file since I created the archive on a Windows system. The weird thing is that I am the owner of this directory. Here is a snippet of the command: ls -l drw-rw-r-- 19 ec2-user ec2-user 4096 May 4 04:09 images When I do "sudo su" and then type the command cd images everything is fine. Why do I get "Permission denied" as ec2-user if I am the owner and have rw permission?

  • modifying constants in objective c during run time

    - by moshikafya
    I am trying to solve the following problem. I have the following constants in my header file: #define PREFS_MY_CONSTANT_1 @"bla1" #define PREFS_MY_CONSTANT_2 @"bla2" #define PREFS_MY_CONSTANT_3 @"bla3" ... In one of my functions, I'd like to print to the UIbutton one of those strings based on user input, so say the user inputs '1', i would show bla1. Instead of creating a huge switch (i have 100 of those), I am looking for a way to combine the constant with the variable holding the user input, so something like that ideally: NSInteger input; [button setTitle:PREFS_MY_CONSTANT_{$input} forState: UIControlStateNormal]; Is something like that possible? what would be the best way to solve this?

  • Responsive width for iPhone

    - by Alex Marchant
    This is my first time building a responsive site, and as I tailor the CSS for the iPhone I'm running into a problem. The styles all apply correctly, the text changes size and the wrapper changes widths. The problem is the iPhone browser still opens up at a huge width, see the screenshot: I'm using @media all and (max-device-width: 480px) {} to set the specific iPhone css. body {width:;} doesn't work. Thanks for the help :)

  • R: Cut and labels/breaks length conflict

    - by AkselO
    I am working with the cut function to prep data for a barplot histogram but keep running into a seeming inconsistency between my labels and breaks: Error in cut.default(sample(1:1e+05, 500, T), breaks = sq, labels = sprintf("$%.0f", : labels/breaks length conflict Here is an example. I pretend that it is income data, using a sequence of 0 to $100,000 in bins of $10,000. I use the same variable to generate both breaks and labels, with minor formating on the label side. I thought they might for some reason have different lengths when comparing to a character vector, but they appear to have the same length, still. > sq<-seq(0,100000,10000) > cut(sample(1:100000, 500, T),breaks=sq,labels=sprintf("$%.0f",sq)) > length(sprintf("$%.0f",sq)) [1] [11] > length(sq) [1] [11]

  • Multi-user job/task tracking/queue software

    - by Bmsgaffer86
    Background: I test and repair electronic products with a team. There are many 'jobs' going through my lab at any point in time. It is getting difficult to track whats coming in and going out because I don't do every test or repair myself. Target: User can enter a job when they drop it off in my lab, and it will appear on the master list or queue. Needs to have priorities and due dates that can be adjusted by users. Ideally this would be web based and open-source, but I am flexible. Dream: A large monitor displaying a list of jobs in the master queue with details. This is very optional though, and would be in the best case scenario. I have done MANY hours of Google-ing and I am not sure if I have been using the right terminology, but I have not found anything that is simple enough to stand alone yet complex enough to be multi-user based. I am mildly proficient in VB, and have the drive to piece anything together that I have to. I am open to ANY help or suggestions.

    In C++: class Rectangle { int x, y; public: void set_values (int,int); int area () {return (x*y);} }; int main () { Rectangle rect; rect.set_values (3,4); } In Java: class Rectangle { int x, y; void set_values (int x,int y); int area () {return (x*y);} } public static void main(String[] args) { Rectangle rect=new Rectangle(3,4); } In C++ compiler will create rect object & reserve memory 4 bytes. I want to know How Java is creating object?

  • Swiping Images with Page Control in Iphone

    - by lakesh
    I am trying to make practice app where i can scroll images with page control. I am able to scroll images and able to include the page control. But the problem i face is i am not able to interlink the two. Meaning to say when I scroll the images, the page control is not affected and when i change the page control, the scrolling of the images is unaffected. I have referred to this: http://www.iosdevnotes.com/2011/03/uiscrollview-paging/ for the scrolling with page control. Viewcontroller.h #import <UIKit/UIKit.h> @interface ViewController : UIViewController <UIScrollViewDelegate>{ UIScrollView *scrollView; UIPageControl *pageControl; BOOL pageControlBeingUsed; } @property (nonatomic, retain) IBOutlet UIScrollView *scrollView; @property (nonatomic, retain) IBOutlet UIPageControl *pageControl; - (IBAction)changePage; @end Viewcontroller.m #import "ViewController.h" @interface ViewController () @end @implementation ViewController @synthesize scrollView,pageControl; - (void)viewDidLoad { [super viewDidLoad]; NSArray *images = [[NSArray alloc] initWithObjects:[UIImage imageNamed:@"1.jpeg"],[UIImage imageNamed:@"2.jpeg"],[UIImage imageNamed:@"3.jpeg" ], nil]; self.scrollView.contentSize = CGSizeMake(self.scrollView.frame.size.width * images.count, self.scrollView.frame.size.height); for (int i = 0; i < images.count; i++) { CGRect frame; frame.origin.x = self.scrollView.frame.size.width * i; frame.origin.y = 0; frame.size = self.scrollView.frame.size; UIImageView* imgView = [[UIImageView alloc] init]; imgView.image = [images objectAtIndex:i]; imgView.frame = frame; [scrollView addSubview:imgView]; } } - (void)didReceiveMemoryWarning { [super didReceiveMemoryWarning]; // Dispose of any resources that can be recreated. } - (void)viewDidUnload { // Release any retained subviews of the main view. // e.g. self.myOutlet = nil; self.scrollView = nil; } - (void)scrollViewDidScroll:(UIScrollView *)sender { // Update the page when more than 50% of the previous/next page is visible CGFloat pageWidth = self.scrollView.frame.size.width; int page = floor((self.scrollView.contentOffset.x - pageWidth / 2) / pageWidth) + 1; self.pageControl.currentPage = page; } - (IBAction)changePage{ // update the scroll view to the appropriate page CGRect frame; frame.origin.x = self.scrollView.frame.size.width * self.pageControl.currentPage; frame.origin.y = 0; frame.size = self.scrollView.frame.size; [self.scrollView scrollRectToVisible:frame animated:YES]; pageControlBeingUsed = YES; } - (void)scrollViewWillBeginDragging:(UIScrollView *)scrollView { pageControlBeingUsed = NO; } - (void)scrollViewDidEndDecelerating:(UIScrollView *)scrollView { pageControlBeingUsed = NO; } @end Need some guidance on this...

  • Dynamic function arguments in C++, possible?

    - by Jeshwanth Kumar N K
    I am little new to C++, I have one doubt in variable argument passing. As I mentioned in a sample code below ( This code won't work at all, just for others understanding of my question I framed it like this), I have two functions func with 1 parameter and 2 parameters(parameter overloading). I am calling the func from main, before that I am checking whether I needs to call 2 parameter or 1 parameter. Here is the problem, as I know I can call two fuctions in respective if elseif statements, but I am curious to know whether I can manage with only one function. (In below code I am passing string not int, as I mentioned before this is just for others understanding purpose. #include<iostream.h> #include <string> void func(int, int); void func(int); void main() { int a, b,in; cout << "Enter the 2 for 2 arg, 1 for 1 arg\n"; cin << in; if ( in == 2) { string pass = "a,b"; } elseif ( in == 1) { string pass = "a"; } else { return 0; } func(pass); cout<<"In main\n"<<endl; } void func(int iNum1) { cout<<"In func1 "<<iNum1<<endl; } void func(int iNum1, int iNum2) { cout<<"In func2 "<<iNum1<<" "<<iNum2<<endl; }

  • How to copy bytes from buffer into the managed struct?

    - by Chupo_cro
    I have a problem with getting the code to work in a managed environment (VS2008 C++/CLI Win Forms App). The problem is I cannot declare the unmanaged struct (is that even possible?) inside the managed code, so I've declared a managed struct but now I have a problem how to copy bytes from buffer into that struct. Here is the pure C++ code that obviously works as expected: typedef struct GPS_point { float point_unknown_1; float latitude; float longitude; float altitude; // x10000 float time; int point_unknown_2; int speed; // x100 int manually_logged_point; // flag (1 --> point logged manually) } track_point; int offset = 0; int filesize = 256; // simulates filesize int point_num = 10; // simulates number of records int main () { char *buffer_dyn = new char[filesize]; // allocate RAM // here, the file would have been read into the buffer buffer_dyn[0xa8] = 0x1e; // simulates the speed data (1e 00 00 00) buffer_dyn[0xa9] = 0x00; buffer_dyn[0xaa] = 0x00; buffer_dyn[0xab] = 0x00; offset = 0x90; // if the data with this offset is transfered trom buffer // to struct, int speed is alligned with the buffer at the // offset of 0xa8 track_point *points = new track_point[point_num]; points[0].speed = 0xff; // (debug) it should change into 0x1e memcpy(&points[0],buffer_dyn+offset,32); cout << "offset: " << offset << "\r\n"; //cout << "speed: " << points[0].speed << "\r\n"; printf ("speed : 0x%x\r\n",points[0].speed); printf("byte at offset 0xa8: 0x%x\r\n",(unsigned char)buffer_dyn[0xa8]); // should be 0x1e delete[] buffer_dyn; // release RAM delete[] points; /* What I need is to rewrite the lines 29 and 31 to work in the managed code (VS2008 Win Forms C++/CLI) What should I have after: array<track_point^>^ points = gcnew array<track_point^>(point_num); so I can copy 32 bytes from buffer_dyn to the managed struct declared as typedef ref struct GPS_point { float point_unknown_1; float latitude; float longitude; float altitude; // x10000 float time; int point_unknown_2; int speed; // x100 int manually_logged_point; // flag (1 --> point logged manually) } track_point; */ return 0; } Here is the paste to codepad.org so it can be seen the code is OK. What I need is to rewrite these two lines: track_point *points = new track_point[point_num]; memcpy(&points[0],buffer_dyn+offset,32); to something that will work in a managed application. I wrote: array<track_point^>^ points = gcnew array<track_point^>(point_num); and now trying to reproduce the described copying of the data from buffer over the struct, but haven't any idea how it should be done. Alternatively, if there is a way to use an unmanaged struct in the same way shown in my code, then I would like to avoid working with managed struct.

  • A view interface for large object/array dumps

    - by user685107
    I want to embed in a page a detailed structure report of my model objects, like print_r() or var_export() produce (now I’m doing this with running var_export() on get_object_vars()). But what I actually want to see is only some properties (in most cases), but at this moment I have to use Ctrl+F and seek the variable I want, instead of just staring at it right after the page completes loading. So I’m embedding buttons to show/hide large arrays etc. but thought: ‘What if there already is the thing I do right now?’ So is there? Update: What would your ideal interface look like? First of all, dumped models fit in the first screen. All the properties can be seen at the first look at the screen (there are not many of them, around 10 per each, three models total, so it is possible). Small arrays can be shown unrolled too. Let the size of the array to count it as ‘small’ be definable. Ideally, the user can see values of the properties without doing any click, scrolling the screen or typing something. There must be some improvements to representing the values, say, if an array is empty, show array ‘My_big_array’ is empty and if a boolean variable starting with is_, has_, had_ has a false as the value, make the variable (let us take is_available for example) shown as is_NOT_available in red, and if it has true as the value, show is_available in green. Without any value shown. The same goes for defined constants. That would be ideal. I want to make focus on this kind of switches. Krumo seems useful, but since it always closes up the variable without making difference of how large it is, I cannot use it as is, but there might appear something similar on github soon :) Second update starts here: Any programmer who sees is_available = false will know what it means, no need to do more Bringing in color indication I forgot about one thing: the ‘switches’ let’s call them so, may me important or not. So I have right now some of them that will show in green or red, this is for something global, like caching, which is shown as Caching is… ON with ‘ON’ written in green, (and ‘OFF’ in red when disabled) while the words about what it is, i.e. ‘Caching is… ’ are written in black. And some which are not so important, for example I haven’t defined REVEAL_TIES is… not set with ‘not set’ written in gray, while the words describing what it is stay in black. And if it would be set the whole phrase would be in black since there is nothing important: if this small utility for showing some undercover things is working, I will see some messages after it, if it isn’t — site will be working independently of its state. Dividing switches into important ones and not with corresponding color match should improve readability, especially for those users who are not programmers and just enabled debug mode because some guy from bugzilla said do that — for them it would help to understand what is important and what is not.

  • Lookback API: How long is a defect in a particular state?

    - by user1195996
    We have a state in our defects called "Need More Information". I would like to create a graph over time of how many defects are in that state at any particular period of time. I think I can get the info to do that with the Lookback API with the following query: my $find = { State => 'Need More Information', '_PreviousValues.State' => {'$ne' => 'Need More Information'}, _TypeHierarchy => -51006, # defect _ValidFrom => { '$gte' => '2012-09-01TZ', '$lt' => '2012-10-23TZ', } I thought that would give me back a list of all defect snapshots where the defect was transitioning into "Need More Information" state, but it does not (seems to list everything that was ever in "Need More Information" state. Technically what I need is a query that lists snapshots of any defects transitioning either TO OR FROM the "Need More Information" state, but since this simpler one did not seem to work as I expected, I thought I would ask first why the query above did not work the way I expected.

  • How to load src in html5 Video tag from JavaScript?

    - by luis_laurent
    Here is the thing, I'm working with ASP.NET and I'm using this particular SignalR library to broadcast a video to my clients, but as far as I know I can not stream video because signalR is a messaging system and it is not intended to stream video, files or things like that. Now what I am trying to do is to split the video into buffers that is Base64-encoded into a string, then on the client I am decoding this string and I am trying to load it into the source of a Video tag. Here I show you what I am doing on the client: HTML Code: <video id="myVideo"> <source id="video_source"> </video> Javascript Code: //here somehow I am getting the string with the base64-encoded video function playVideo(message) { var myVideo = document.getElementById("myVideo"); var mySource = document.getElementById("video_source"); mySource.setAttribute("src", getEncodedVideoString("avi", message)); myVideo.load(); myVideo.play(); }; // here I am formatting and concatenating the string for my source attribute function getEncodedVideoString(type, file) { return 'data:video/' + type + ';base64,' + $.base64.decode(file); } Well as you can see, at the moment I'm facing a scenario a little weird, but I already have the video encoded on the client, now I just need to find out the way to reproduce that video. And here is when my question comes up, does any one has done something like this before, or you have any idea or suggestion to do that? P.S I am using this jquery-base64 library to decode my string
