  • .htaccess / 301 redirection question

    - by John K
    All my WordPress post URLs generate subdirectories with duplicate content and I do not know what regular expression to use to consistently 301 redirect domain.com/category/post/random-number/ to domain.com/category/post/ and domain.com/category/post/random-number/another-random-number/ also to domain.com/category/post/. Here is an example of my problem: http://www.example.com/features/harb-constitution-not-to-allow-kr-provinces-to-receive-foreign-officials/ http://www.example.com/features/harb-constitution-not-to-allow-kr-provinces-to-receive-foreign-officials/1345257927000/

  • Can't detect collision properly using Rectangle.Intersects()

    - by Daniel Ribeiro
    I'm using a single sprite sheet image as the main texture for my breakout game. The image is this: My code is a little confusing, since I'm creating two elements from the same Texture using a Point, to represent the element size and its position on the sheet, a Vector, to represent its position on the viewport and a Rectangle that represents the element itself. Texture2D sheet; Point paddleSize = new Point(112, 24); Point paddleSheetPosition = new Point(0, 240); Vector2 paddleViewportPosition; Rectangle paddleRectangle; Point ballSize = new Point(24, 24); Point ballSheetPosition = new Point(160, 240); Vector2 ballViewportPosition; Rectangle ballRectangle; Vector2 ballVelocity; My initialization is a little confusing as well, but it works as expected: paddleViewportPosition = new Vector2((GraphicsDevice.Viewport.Bounds.Width - paddleSize.X) / 2, GraphicsDevice.Viewport.Bounds.Height - (paddleSize.Y * 2)); paddleRectangle = new Rectangle(paddleSheetPosition.X, paddleSheetPosition.Y, paddleSize.X, paddleSize.Y); Random random = new Random(); ballViewportPosition = new Vector2(random.Next(GraphicsDevice.Viewport.Bounds.Width), random.Next(GraphicsDevice.Viewport.Bounds.Top, GraphicsDevice.Viewport.Bounds.Height / 2)); ballRectangle = new Rectangle(ballSheetPosition.X, ballSheetPosition.Y, ballSize.X, ballSize.Y); ballVelocity = new Vector2(3f, 3f); The problem is I can't detect the collision properly, using this code: if(ballRectangle.Intersects(paddleRectangle)) { ballVelocity.Y = -ballVelocity.Y; } What am I doing wrong?

  • Getting random objects from an array, and if the objects are the same, get a new object.

    - by XcodeDev
    Hi, I have made a jokes application, where the user generates a joke and the joke will display in a UILabel. However I am trying to randomise the jokes show, but I do not want to show the same joke twice. Please could you tell me how I could do this. I am using the code below to try and do that, but it seems that it is not working. - (IBAction)generateNewJoke { if (i < [jokeArray count]) { i++; [userDefaults setInteger:[userDefaults integerForKey:kNewIndex] forKey:kOldIndex]; int oldnumber = [userDefaults integerForKey:kOldIndex]; int newnumber = [userDefaults integerForKey:kNewIndex]; [answerLabel setText:@""]; [userDefaults setInteger:i forKey:kNewIndex]; if (oldnumber == newnumber) { NSLog(@"they are the same"); [userDefaults setInteger:arc4random()%[jokeArray count] forKey:kNewIndex]; } [jokeLabel setText:[jokeArray objectAtIndex:[userDefaults integerForKey:kNewIndex]]]; } }

  • Most valued skill set in web development industry/what should I be doing now? (Kinda random "career"

    - by Andrew
    I want to be a web programmer [when I grow up?] because it's what I like doing, and I really do thoroughly enjoy it (web development in general, actually). I have about 2 years experience with PHP, CSS, and HTML and a few months experiance with JS and jQuery. I've been wondering this for a while -- what languages should I be most familiar with if I want to try and make a career out of web development? I'm only 17, so I've got plenty of time, and I think I've got a decent headstart on things, but it doesn't hurt to ask. If I'm thinking in terms of being able to get hired as a web programmer, what is (or what are...?) the most useful thing I can do now to be able to have an upper hand when it comes to looking for a job. What languages, as a young programmer, should I really focus on? If you were looking to hire a developer, what would you be looking for?

  • What's the best way to unit test code that generates random output?

    - by Flynn1179
    Specifically, I've got a method picks n items from a list in such a way that a% of them meet one criterion, and b% meet a second, and so on. A simplified example would be to pick 5 items where 50% have a given property with the value 'true', and 50% 'false'; 50% of the time the method would return 2 true/3 false, and the other 50%, 3 true/2 false. Statistically speaking, this means that over 100 runs, I should get about 250 true/250 false, but because of the randomness, 240/260 is entirely possible. What's the best way to unit test this? I'm assuming that even though technically 300/200 is possible, it should probably fail the test if this happens. Is there a generally accepted tolerance for cases like this, and if so, how do you determine what that is?

  • Random <hr/> that I don't know how to get rid of!

  • I hyperlinked a cell in excel 2003, formula issues?

    - by joseinsomniac
    I have a budget spreadsheet using excel 2003. I have My deposit, then all of my bills, the total, then a cell that has the difference(between the amount of deposit and the total of the bills). The difference cell numbers turn red when I dont have enough money (deposit vs bill total). I hyperlinked the difference cell to a checkbook register spreadsheet so I can track where all my extra money went(reconsile receipts daily). When hyperlinked the numbers are blue. I need the numbers to stay black(when above 0.00) and stay red (when the numbers are below 0.00) and not change after the link has been clicked on. Also if the link has not been clicked on, and the numbers are red, the font is smaller, even though the toolbar shows the font size hasnt changed. After I click on it and go back to the budget sheet, its the size it should be. Any Ideas? Thanks!

  • Is this an effective monetization method for an Android game? [on hold]

    - by Matthew Page
    The short version: I plan to make an Android puzzle game where the user tries to get 3-6 numbers to their predetermined goal numbers. The free version of the app will have three predetermined levels (easy, medium, hard). The full version ($0.99, probably) will have a level generator where there will be unlimited easy, medium, or hard levels, as well as a custom difficulty option where users can set specific vales to the number of numbers to equate to their goal, the number of buttons to use, etc. Users will also have the option to get a one-time "hint" for a fee of $0.49, or unlimited hints for a one-time fee of $2.99. The long version: Mechanics of Game and Victory The application is a number puzzle. When the user begins a new game, depending on the input by the user, between 3 and 6 numbers show up on the top of the screen, and between 3 and 6 buttons show up on the bottom of the screen. The buttons all have two options: to increase every number the same way, or decrease every number the same way. The buttons either use addition / subtraction, multiplication / division, or exponents / roots, all depending on the number displayed on the button. Addition buttons are green, multiplication buttons are blue, and exponential buttons are red. The user wins when all of the numbers displayed on the screen equate to their goal number, displayed below each number. Monetization If the user is playing the full (priced) version of the app, upon the start of the game, the user will be confronted with a dialogue asking for the number of buttons and the number of numbers to equate in the game. Then, based on the user input, a random puzzle will be generated. If the user is playing the free version of the app, the user will be asked to either play an “easy”, “hard”, or “expert” puzzle. A pre-determined puzzle from each category will be used in the game. If the user has played that puzzle before, a dialogue will show saying this to the user and advertising the full version of the app. The full version of the app will also be advertised upon the successful or in successful completion of a puzzle. Upon exiting this advertisement, another full screen advertisement will appear from a third party. Also, the solution to the puzzle should be stored by the program, and if the user pays a small fee, he/she can see a hint to the solution to the program. In the free version of the app, the user may use their first hint for free. Also, the user can use unlimited hints for a slightly larger fee. Is this an effective monetization method?

  • LINQ – Skip() and Take() methods

    - by nmarun
    I had this issue recently where I have an array of integers and I’m doing some Skip(n) and then a Take(m) on the collection. Here’s an abstraction of the code: 1: int[] numbers = { 5, 4, 1, 3, 9, 8, 6, 7, 2, 0 }; 2: var taken = numbers.Skip(3).Take(3); 3: foreach (var i in taken) 4: { 5: Console.WriteLine(i); 6: } The output is as expected: 3, 9, 8 – skip the first three and then take the next three items. But, what happens if I do something like: 1: var taken = numbers.Skip(7).Take(5); In English – skip the first seven and the take the next 5 items from an array that contains only 10 elements. Think it’ll throw the IndexOutOfRangeException exception? Nope. These extension methods are a little smarter than that. Even though the user has requested more elements than what exists in the collection, the Take method only returns the first three thereby making the output of the program as: 7, 2, 0. The scenario is handled similarly when you do: 1: var taken = numbers.Take(5).Skip(7); This one takes the first 5 elements from the numbers array and then skips 7 of them. This is what is looks like in the debug mode: Just wanted to share this behavior.

  • MySQL ORDER BY returns things in (apparently) random order !?

    - by Luke H
    The following query: SELECT DISTINCT ClassName FROM SiteTree ORDER BY ClassName is returning things in no apparent order! I get the same result whether I quote column/table names, or use DISTINCT or not, or add ASC or DESC. I assumed the indexes might be broken, or something like this, so tried dropping and recreating. Also tried REPAIR TABLE and CHECK TABLE. The table collation is set to latin1_swedish_ci. All the textual columns are set to use UTF-8 and collation is set to utf8_general_ci What could be causing this?

  • What causes extra space and random alignment in my divs using the 960 grid system?

    - by tomdot
    I have an issue where elements in divs seemingly align randomly, not responding to any align tag, and where divs create extra space above or below its element. I'm using the 960 grid system and I have not altered the stock CSS file lest my fingers blow it up. I've put up a test page here, and please excuse some of the dodgy code :-D It's still in it's very early stages (as am I), but I don't feel I can move on until I can comfortably understand what is causing the issue. The best example on that page is the bottom horizontal bar and elements underneath. The bar adds a few pixels of dead space, and the elements below that align to different parts of their respective divs. Why is it that elements seemingly do not standardise their alignment given no instruction, and what causes extra space again where no instruction was given? My own thought was to relatively position everything individually, but I'm worried this will cause issues and 'break' the grid. Other than that, I unno. Thanks

  • Recognizing text fields according to their label value

    - by Pierpaolo Bagnasco
    I have an application who has text fields (not select, not checkbox or other types) where an user can enter some value, like this: ISBN and E-Mail are the label of each input. Now I have to automatically test these inputs according to their label. The question is: how to recognize that, for example, the first input requires an ISBN code? I programmed something like this: turn the label value to lowercase check if the label value contains isbn if so set the field value to a random ISBN code (i.e.: 1234567890), else set it to a random value (default) For the email field: turn the label value to lowercase check if the label value contains e-mail or email or mail if so set the field value to a random email (i.e.: [email protected]), else set it to a random value (default) And so on for each text field I encounter. Is that reliable? How can I improve the "recognizing part"? I know only the label value and the field value (what is already written in the field by default) for each text input.

    I have this code i have been using....but i need a conditional where it will read all the sub directories of /bg to select an image as opposed to a specific folder if they were on a subpage.

  • How to get a random node from a tree?

    - by ooboo
    It looks easy, but I found the implementation tricky. I need that for a simple genetic programming problem I'm trying to implement. The function should, given a node, return the node itself or any of its children such that the probability of choosing a node is normally distributed relative to its depth (so the function should return mostly middle nodes, but sometimes the root itself or the lowest ones - but that's not really necessary if that makes it significantly more complex, if all any node is chosen with equal probability, that's good enough). Thanks

I think I can do that if I call operator++ several times, but isn't that a little bit dirty?
