  • Variable number of GUI Buttons

    - by Wakaka
    I have a generic HTML5 Canvas GUI Button class and a Scene class. The Scene class has a method called createButton(), which will create a new Button with onclick parameter and store it in a list of buttons. I call createButton() for all UI buttons when initializing the Scene. Because buttons can appear and disappear very often during rendering, Scene would first deactivate all buttons (temporarily remove their onclick, onmouseover etc property) before each render frame. During rendering, the renderer would then activate the required buttons for that frame. The problem is that part of the UI requires a variable number of buttons, and their onclick, onmouseover etc properties change frequently. An example is a buffs system. The UI will list all buffs as square sprites for the current unit selected, and mousing over each square will bring up a tooltip with some information on the buff. But the number of buffs is variable thus I won't know how many buttons to create at the start. What's the best way to solve this problem? P.S. My game is in Javascript, and I know I can use HTML buttons, but would like to make my game purely Canvas-based. Create buttons on-the-fly during rendering. Thus I will only have buttons when I require them. After the render frame these buttons would be useless and removed. Create a fixed set of buttons that I'm going to assume the number of buffs per unit won't exceed. During each render frame activate the buttons accordingly and set their onmouseover property. Assign a button to each Buff instance. This sounds wrong as the buff button is a part of the GUI which can only have one unit selected. Assigning a button to every single Buff in the game seems to be overkill. Also, I would need to change the button's position every render frame since its order in the unit's list of buffs matter. Any other solutions? I'm actually quite for idea (1) but am worried about the memory/time issues of creating a new Button() object every render frame. But this is in Javascript where object creation is oh-so-common ({} mainly) due to automatic garbage collection. What is your take on this? Thanks!

  • Multi-threaded JOGL Problem

    - by moeabdol
    I'm writing a simple OpenGL application in Java that implements the Monte Carlo method for estimating the value of PI. The method is pretty easy. Simply, you draw a circle inside a unit square and then plot random points over the scene. Now, for each point that is inside the circle you increment the counter for in points. After determining for all the random points wither they are inside the circle or not you divide the number of in points over the total number of points you have plotted all multiplied by 4 to get an estimation of PI. It goes something like this PI = (inPoints / totalPoints) * 4. This is because mathematically the ratio of a circle's area to a square's area is PI/4, so when we multiply it by 4 we get PI. My problem doesn't lie in the algorithm itself; however, I'm having problems trying to plot the points as they are being generated instead of just plotting everything at once when the program finishes executing. I want to give the application a sense of real-time display where the user would see the points as they are being plotted. I'm a beginner at OpenGL and I'm pretty sure there is a multi-threading feature built into it. Non the less, I tried to manually create my own thread. Each worker thread plots one point at a time. Following is the psudo-code: /* this part of the code exists in display() method in MyCanvas.java which extends GLCanvas and implements GLEventListener */ // main loop for(int i = 0; i < number_of_points; i++){ RandomGenerator random = new RandomGenerator(); float x = random.nextFloat(); float y = random.nextFloat(); Thread pointThread = new Thread(new PointThread(x, y)); } gl.glFlush(); /* this part of the code exists in run() method in PointThread.java which implements Runnable */ void run(){ try{ gl.glPushMatrix(); gl.glBegin(GL2.GL_POINTS); if(pointIsIn) gl.glColor3f(1.0f, 0.0f, 0.0f); // red point else gl.glColor3f(0.0f, 0.0f, 1.0f); // blue point gl.glVertex3f(x, y, 0.0f); // coordinates gl.glEnd(); gl.glPopMatrix(); }catch(Exception e){ } } I'm not sure if my approach to solving this issue is correct. I hope you guys can help me out. Thanks.

  • Is there a fix to display 0 when arithmetic underflow occurs on the Windows 7 calculator?

    - by Pascal Qyy
    I have a problem that exasperates me: When I take the Windows 7 calculator in standard mode, if I do 4, then v (square root), the result is 2 Fine. But, at this point, if I do - (minus), then 2, the result is -1,068281969439142e-19 instead of 0! OK, I know about ? (machine epsilon), and yes, -1,068281969439142e-19 is less than the 64 bits ? (1.11e-16), so, we have an arithmetic underflow, in other words in this case: 0. Great, my computer is able to represent subnormal numbers instead of just flush to zero when this happens, and it seems that it is an improvement! Subnormal values fill the underflow gap with values where the absolute distance between them are the same as for adjacent values just outside of the underflow gap. This is an improvement over the older practice to just have zero in the underflow gap, and where underflowing results were replaced by zero (flush to zero). BUT: this result is false! when you try to explain the concept of the square root to a child and you end up with this kind of result, it only complicates your task... what is the point to represent subnormal numbers in a standard, non scientific calculator? So, is there a way to fix this?

  • How to add URL's to wiki (MediaWiki) powered documentation?

    - by Ian Boyd
    We have an internal company wiki. The wiki engine being used is MediaWiki, the wiki engine that runs Wikipedia. Some of it contains IT stuff. One of the things i want want to have are hyperlinks to the various virtual machines. An example of a command, as it needs to run, is: vmrc://solo.avatopia.com:5901/Windows 2000 Server My first thought was to convert the URL into a link: [vmrc://solo.avatopia.com:5901/Windows 2000 Server] But the content renders literally as above: with the square brackets and all. Testing with other URL protocols: [http://solo.avatopia.com] [ftp://solo.avatopia.com] [ldap://solo.avatopia.com] [vmrc://solo.avatopia.com] Only the first two work, and are converted to hyperlinks. The other two remain as liternal text. How can i add URLs to MediaWiki powered documentation? Original Question We have an internal company wiki. The wiki engine being used is MediaWiki, the wiki engine that runs Wikipedia. Some of it contains IT stuff. One of the things i want want to have are hyperlinks to the various virtual machines. An example of a command, as it needs to run, is: \\solo\VMRC Client\vmrc.exe solo.avatopia.com:5901/Windows 2000 Server If launching from a command prompt, you have to quote the spaces: C:\>"\\solo\VMRC Client\vmrc.exe" solo.avatopia.com:5901/"Windows 2000 Server" My first thought in converting the above for use on our wiki-site, is to simply HTML-ify it: file://\\solo\VMRC Client\vmrc.exe solo.avatopia.com:5901/&quot;Windows 2000 Server&quot; but MediaWiki only converts file://\solo\VMRC to a hyperlink, the remainder is text. i've tried other random things, including enclosing the URL in square brackets. What is the correct answer? i don't want to happen to randomly stumble on some format that happens to work today, and breaks in the future.

  • Certain Japanese characters aren't displayed properly

    - by Nisto
    On the following site: http://www.nciku.com/search/radical the first 2 characters on the second row of the "Step 2" table aren't displayed properly. All other characters look fine. I tried re-installing the Asian fonts via the checkboxes regarding Asian fonts in the "Regional and Language Options" control panel applet. I have tried removing every single Font from the Fonts folder (some were ofcourse not possible to remove), and re-installing them all again. I did this by... Running cmd Closing down the explorer process In cmd; using the command DEL /F /S /Q * in the Fonts folder Putting in my XP SP3 Retail disc In cmd; using expand -r *.tt_ in the I386 folder on the XP disc (and any other font file, in the I386\LANG folder) I also tried installing this pack from Microsoft, but this solved nothing either. I even tried running my browser (Firefox) through AppLocale. And changing character encoding -- again, does not help. I've also tried viewing the page in Internet Explorer. What could be wrong? I have checked my Fonts folder, to make sure that every single font available on the XP disc is available in WINDOWS\Fonts. What shows in the first square on the second row - I can't really tell what it's supposed to look like (but it's not the proper character)... but the second square shows a rectangular symbol containing HEX code. I've been in this situation before -- and it has been when I've been missing fonts. But how could I possibly be missing a necessary font? Shouldn't it be provided in the Asian "font packages"? I've talked to some other users that has viewed the page, and they had no problems displaying those characters on second row - even though they're only using the fonts provided on the Windows installation disc. Windows XP Professional Service Pack 3 (x86 - with latest updates) Firefox 3.6.15

  • Redirect all access requests to a domain and subdomain(s) except from specific IP address? [closed]

    - by Christopher
    This is a self-answered question... After much wrangling I found the magic combination of mod_rewrite rules so I'm posting here. My scenario is that I have two domains - domain1.com and domain2.com - both of which are currently serving identical content (by way of a global 301 redirect from domain1 to domain2). Domain1 was then chosen to be repurposed to be a 'portal' domain - with a corporate CMS-based site leading off from the front page, and the existing 'retail' domain (domain2) left to serve the main web site. In addition, a staging subdomain was created on domain1 in order to prepare the new corporate site without impinging on the root domain's existing operation. I contemplated just rewriting all requests to domain2 and setting up the new corporate site 'behind the scenes' without using a staging domain, but I usually use subdomains when setting up new sites. Finally, I required access to the 'actual' contents of the domains and subdomains - i.e., to not be redirected like all other visitors - in order that I can develop the new site and test it in the staging environment on the live server, as I'm not using a separate development webserver in this case. I also have another test subdomain on domain1 which needed to be preserved. The way I eventually set it up was as follows: (10.2.2.1 would be my home WAN IP) .htaccess in root of domain1 RewriteEngine On RewriteCond %{REMOTE_ADDR} !^10\.2\.2\.1 RewriteCond %{HTTP_HOST} !^staging.domain1.com$ [NC] RewriteCond %{HTTP_HOST} !^staging2.domain1.com$ [NC] RewriteRule ^(.*)$ http://domain2.com/$1 [R=301] .htaccess in staging subdomain on domain1: RewriteEngine On RewriteCond %{REMOTE_ADDR} !^10\.2\.2\.1 RewriteCond %{HTTP_HOST} ^staging.revolver.coop$ [NC] RewriteRule ^(.*)$ http://domain2.com/$1 [R=301,L] The multiple .htaccess files and multiple rulesets require more processing overhead and longer iteration as the visitor is potentially redirected twice, however I find it to be a more granular method of control as I can selectively allow more than one IP address access to individual staging subdomain(s) without automatically granting them access to everything else. It also keeps the rulesets fairly simple and easy to read. (or re-interpret, because I'm always forgetting how I put rules together!) If anybody can suggest a more efficient way of merging all these rules and conditions into just one main ruleset in the root of domain1, please post! I'm always keen to learn, this post is more my attempt to preserve this information for those who are looking to redirect entire domains for all visitors except themselves (for design/testing purposes) and not just denying specific file access for maintenance mode (there are many good examples of simple mod_rewrite rules for 'maintenance mode' style operation easily findable via Google). You can also extend the IP address detection - firstly by using wildcards ^10\.2\.2\..*: the last octet's \..* denotes the usual "." and then "zero or more arbitrary characters", signified by the .* - so you can specify specific ranges of IPs in a subnet or entire subnets if you wish. You can also use square brackets: ^10\.2\.[1-255]\.[120-140]; ^10\.2\.[1-9]?[0-9]\.; ^10\.2\.1[0-1][0-9]\. etc. The third way, if you wish to specify multiple discrete IP addresses, is to bracket them in the style of ^(1.1.1.1|2.2.2.2|3.3.3.3)$, and you can of course use square brackets to substitute octets or single digits again. NB: if you're using individual RewriteCond lines to specify multiple IPs / ranges, make sure to put [OR] at the end of each one otherwise mod_rewrite will interpret as "if IP address matches 1.1.1.1 AND if IP address matches 2.2.2.2... which is of course impossible! However as far as I'm aware this isn't necessary if you're using the ! negator to specify "and is not...". Kudos also to SE: this older question also came in useful when I was verifying my own knowledge prior to my futzing around with code. This page was helpful, as were the various other links posted below (can't hyperlink them all due to spam protection... other regex checkers are available). The AddedBytes cheat sheet's useful to pin up on your wall.

  • SQL SERVER – Puzzle #1 – Querying Pattern Ranges and Wild Cards

    - by Pinal Dave
    Note: Read at the end of the blog post how you can get five Joes 2 Pros Book #1 and a surprise gift. I have been blogging for almost 7 years and every other day I receive questions about Querying Pattern Ranges. The most common way to solve the problem is to use Wild Cards. However, not everyone knows how to use wild card properly. SQL Queries 2012 Joes 2 Pros Volume 1 – The SQL Queries 2012 Hands-On Tutorial for Beginners Book On Amazon | Book On Flipkart Learn SQL Server get all the five parts combo kit Kit on Amazon | Kit on Flipkart Many people know wildcards are great for finding patterns in character data. There are also some special sequences with wildcards that can give you even more power. This series from SQL Queries 2012 Joes 2 Pros® Volume 1 will show you some of these cool tricks. All supporting files are available with a free download from the www.Joes2Pros.com web site. This example is from the SQL 2012 series Volume 1 in the file SQLQueries2012Vol1Chapter2.2Setup.sql. If you need help setting up then look in the “Free Videos” section on Joes2Pros under “Getting Started” called “How to install your labs” Querying Pattern Ranges The % wildcard character represents any number of characters of any length. Let’s find all first names that end in the letter ‘A’. By using the percentage ‘%’ sign with the letter ‘A’, we achieve this goal using the code sample below: SELECT * FROM Employee WHERE FirstName LIKE '%A' To find all FirstName values beginning with the letters ‘A’ or ‘B’ we can use two predicates in our WHERE clause, by separating them with the OR statement. Finding names beginning with an ‘A’ or ‘B’ is easy and this works fine until we want a larger range of letters as in the example below for ‘A’ thru ‘K’: SELECT * FROM Employee WHERE FirstName LIKE 'A%' OR FirstName LIKE 'B%' OR FirstName LIKE 'C%' OR FirstName LIKE 'D%' OR FirstName LIKE 'E%' OR FirstName LIKE 'F%' OR FirstName LIKE 'G%' OR FirstName LIKE 'H%' OR FirstName LIKE 'I%' OR FirstName LIKE 'J%' OR FirstName LIKE 'K%' The previous query does find FirstName values beginning with the letters ‘A’ thru ‘K’. However, when a query requires a large range of letters, the LIKE operator has an even better option. Since the first letter of the FirstName field can be ‘A’, ‘B’, ‘C’, ‘D’, ‘E’, ‘F’, ‘G’, ‘H’, ‘I’, ‘J’ or ‘K’, simply list all these choices inside a set of square brackets followed by the ‘%’ wildcard, as in the example below: SELECT * FROM Employee WHERE FirstName LIKE '[ABCDEFGHIJK]%' A more elegant example of this technique recognizes that all these letters are in a continuous range, so we really only need to list the first and last letter of the range inside the square brackets, followed by the ‘%’ wildcard allowing for any number of characters after the first letter in the range. Note: A predicate that uses a range will not work with the ‘=’ operator (equals sign). It will neither raise an error, nor produce a result set. --Bad query (will not error or return any records) SELECT * FROM Employee WHERE FirstName = '[A-K]%' Question: You want to find all first names that start with the letters A-M in your Customer table and end with the letter Z. Which SQL code would you use? a. SELECT * FROM Customer WHERE FirstName LIKE 'm%z' b. SELECT * FROM Customer WHERE FirstName LIKE 'a-m%z' c. SELECT * FROM Customer WHERE FirstName LIKE 'a-m%z' d. SELECT * FROM Customer WHERE FirstName LIKE '[a-m]%z' e. SELECT * FROM Customer WHERE FirstName LIKE '[a-m]z%' f. SELECT * FROM Customer WHERE FirstName LIKE '[a-m]%z' g. SELECT * FROM Customer WHERE FirstName LIKE '[a-m]z%' Contest Leave a valid answer before June 18, 2013 in the comment section. 5 winners will be selected from all the valid answers and will receive Joes 2 Pros Book #1. 1 Lucky person will get a surprise gift from Joes 2 Pros. The contest is open for all the countries where Amazon ships the book (USA, UK, Canada, India and many others).

  • Screen Aspect Ratio

    - by Bill Evjen
    Jeffrey Dean, Pixar Aspect Ratio is very important to home video. What is aspect ratio – the ratio from the height to the width 2.35:1 The image is 2.35 times wide as it is high Pixar uses this for half of our movies This is called a widescreen image When modified to fit your television screen They cut this to fit the box of your screen When a comparison is made huge chunks of picture is missing It is harder to find what is going on when these pieces are missing The whole is greater than the pieces themselves. If you are missing pieces – you are missing the movie The soul and the mood is in the film shots. Cutting it to fit a screen, you are losing 30% of the movie Why different aspect ratios? Film before the 1950s 1.33:1 Academy Standard There were all aspects of images though. There was no standard. Thomas Edison developed projecting images onto a wall/screen He didn’t patent it as he saw no value in it. Then 1.37:1 came about to add a strip of sound This is the same size as a 35mm film Around 1952 – TV comes along NTSC Television followed the Academy Standard (4x3) Once TV came out, movie theater attendance plummets So Film brought forth color to combat this. Also early 3D Also Widescreen was brought forth. Cinema-Scope Studios at the time made movies bigger and bigger There was a Napoleon movie that was actually 4x1 … really wide. 1.85:1 Academy Flat 2.35:1 Anamorphic Scope (aka Panavision/Cinemascope) Almost all movies are made in these two aspect ratios Pixar has done half in one and half in the other Why choose one over the other? Artist choice It is part of the story the director wants to tell Can we preserve the story outside of the theaters? TVs before 1998 – they were very square Now TVs are very wide Historical options Toy Story released as it was and people cut it in a way that wasn’t liked by the studio Pan and Scan is another option Cut and then scan left or right depending on where the action is Frame Height Pixar can go back and animate more picture to account for the bottom/top bars. You end up with more sky and more ground The characters seem to get lost in the picture You lose what the director original intended Re-staging For animated movies, you can move characters around – restage the scene. It is a new completely different version of the film This is the best possible option that Pixar came up with They have stopped doing this really as the demand as pretty much dropped off Why not 1.33 today? There has been an evolution of taste and demands. VHS is a linear item The focus is about portability and not about quality Most was pan and scan and the quality was so bad – but people didn’t notice DVD was introduced in 1996 You could have more content – two versions of the film You could have the widescreen version and the 1.33 version People realized that they are seeing more of the movie with the widescreen High Def Televisions (16x9 monitors) This was introduced in 2005 Blu-ray Disc was introduced in 2006 This is all widescreen You cannot find a square TV anymore TVs are roughly 1.85:1 aspect ratio There is a change in demand Users are used to black bars and are used to widescreen Users are educated now What’s next for in-flight entertainment?

  • Collision 2D Quads

    I want to detect collision between two 2D squares, one square is static and the other one moves according to keyboard arrows. I have implemented some code, however nothing happens when they overlap each other and what I tried to achieve in the code was to detect an overlapping between them.

  • JavaScript variable to ColdFusion variable

    - by Alexander
    I have a tricky one. By means of a <cfoutput query="…"> I list some records in the page from a SQL Server database. By the end of each line viewing I try to add this in to a record in a MySQL database. As you see is simple, because I can use the exact variables from the output query in to my new INSERT INTO statement. BUT: the rsPick.name comes from a database with a different character set and the only way to get it right into my new database is to read it from the web page and not from the value came in the output query. So I read this value with that little JavaScript I made and put it in the myValue variable and then I want ColdFusion to read that variable in order to place it in my SQL statement. <cfoutput query="rsPick"> <tr> <td>#rsPick.ABBREVIATION#</td> <td id="square"> #rsPick.name# </td> <td>#rsPick.Composition#</td> <td> Transaction done... <script type="text/javascript"> var myvalue = document.getElementById("square").innerHTML </script> </td> <cfquery datasource="#Request.Order#"> INSERT INTO products (iniid, abbreviation, clsid, cllid, dfsid, dflid, szsid, szlid, gross, retail, netvaluebc, composition, name) VALUES ( #rsPick.ID#, '#rsPick.ABBREVIATION#', #rsPick.CLSID#, #rsPick.CLLID#, #rsPick.DFSID#, #rsPick.DFLID#, #rsPick.SZSID#, #rsPick.SZLID#, #rsPick.GROSSPRICE#, #rsPick.RETAILPRICE#, #rsPick.NETVALUEBC#, '#rsPick.COMPOSITION#','#MYVALUE#' ) </cfquery> </tr> </cfoutput>

  • Android layout with sqare buttons

    I want to make a layout similar to this one: Four square buttons on the screen - each of those using half of the screen with/screen height (whichever is smaler). I already tried to achieve this by using a LinearLayoutbut the buttons are ending up using the correct width, but still having the height of the background (not square any more). <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:orientation="vertical" android:layout_width="fill_parent" android:layout_height="fill_parent"> <LinearLayout android:layout_width="fill_parent" android:layout_height="wrap_content"> <Button android:layout_height="wrap_content" style="@style/CKMainButton" android:layout_width="fill_parent" android:text="@string/sights" android:id="@+id/ApplicationMainSight" android:layout_toLeftOf="@+id/ApplicationMainEvent"></Button> <Button android:layout_height="wrap_content" style="@style/CKMainButton" android:layout_width="fill_parent" android:text="@string/sights" android:id="@+id/ApplicationMainSight" android:layout_toLeftOf="@+id/ApplicationMainEvent"></Button> </LinearLayout> <LinearLayout android:layout_width="fill_parent" android:layout_height="wrap_content"> <Button android:layout_height="wrap_content" style="@style/CKMainButton" android:layout_weight="1" android:layout_width="fill_parent" android:text="@string/usergenerated" android:id="@+id/ApplicationMainUserGenerated"></Button> <Button android:layout_height="wrap_content" style="@style/CKMainButton" android:layout_weight="1" android:layout_width="fill_parent" android:text="@string/tours" android:id="@+id/ApplicationMainTour"></Button> </LinearLayout> </LinearLayout> It's looking like this: How can i acchieve the Layout to look like the image above?

  • drawing different quartz 2d

    - by Cosizzle
    Hello, I'm trying to make a small application or demo thats a tab bar application. Each bar item loads in a new view. I've created a quartzView class that is called on by the controller: - (void)viewDidLoad { quartzView *drawingView = [[quartzView alloc] initWithFrame:CGRectMake(0,0,320,480)]; [self.view addSubview:drawingView]; [super viewDidLoad]; } From my understanding, the drawRect method must be triggered in order to render the object and to draw it. This is my quartzView class: #import "quartzView.h" @implementation quartzView #pragma mark shapes // Blue Circle - (void)drawRect:(CGRect)rect { NSLog(@"Trying to draw..."); CGContextRef ctx = UIGraphicsGetCurrentContext(); //get the current context CGContextClearRect(ctx, rect); //clear off the screen //draw a red square CGContextSetRGBFillColor(ctx, 255, 0, 0, 1); CGContextFillRect(ctx, CGRectMake(10, 10, 50, 50)); } // ==================================================================================================== #pragma mark - - (id)initWithFrame:(CGRect)frame { if (self = [super initWithFrame:frame]) { // Initialization code } return self; } - (void)dealloc { [super dealloc]; } @end So how would I go about to say, if the view is view one, draw a square if it's view two draw a circle. And so on.

  • Background image in a JFrame.

    - by thepandaatemyface
    Hi, This question has been asked a lot but everywhere the answers fall short. I can get a JFrame to display a background image just fine by extending JPanel and overriding paintComponent, like so: class BackgroundPanel extends JPanel { private ImageIcon imageIcon; public BackgroundPanel() { this.imageIcon = Icons.getIcon("foo"); } @Override protected void paintComponent(Graphics g) { super.paintComponent(g); g.drawImage(imageIcon.getImage(), 0,0,imageIcon.getIconWidth(),imageIcon.getIconHeight(),this); } } But now, how do you add a component on top of that background? When I go JFrame w = new JFrame() ; Container cp = w.getContentPane(); cp.setLayout(null); BackgroundPanel bg = new BackgroundPanel(); cp.add(bg); JPanel b = new JPanel(); b.setSize(new Dimension(30, 40)); b.setBackground(Color.red); cp.add(b); w.pack() w.setVisible(true) It shows the little red square (or any other component) and not the background, but when I remove cp.setLayout(null);, the background shows up but not my other component. I'm guessing this has something to do with the paintComponent not being called by the null LayoutManager, but I'm not at all familiar with how LayoutManagers work (this is a project for college and the assignment specifically says not to use a LayoutManager) When i make the image the background has to display null (and so, transparant (??)) the red square shows up so it might be that the background is actually above my other components) Does anyone anyone have any ideas? Thanks

Hi all,now I'm already can convert text files to excell file by python using script that was given from user named Rami Helmy.A big thanks for him.But now,That script will produce more than one excell files depends on the number of '|' from the text files.Beside that,That script also can only convert one text files.I a going to convert all text files without state the name of text files.Therefore,I am looking such a way on how to this script going to: output only one excell file convert all .txt files from the directory that was given from user. output excell's file name are automaticly copied from the file name of text files. I am new in python,hopefully someone can help me to solve my problems.Thank You.. done all the task,but there was something that I'm confused.. that output excell files contains an "square" symbol like this: then, how can I ensure that there is no square symbol like that after I convert from text files to excell? thank you...

  • Collision detection of huge number of circles

    - by Tomek Tarczynski
    What is the best way to check collision of huge number of circles? It's very easy to detect collision between two circles, but if we check every combination then it is O(n^2) which definitely not an optimal solution. We can assume that circle object has following properties: -Coordinates -Radius -Velocity -Direction Velocity is constant, but direction can change. I've come up with two solutions, but maybe there are some better solutions. Solution 1 Divide whole space into overlapping squares and check for collision only with circles that are in the same square. Squares needs to overlap so there won't be a problem when circle moves from one square to another. Solution 2 At the beginning distances between every pair of circles need to be calculated. If the distance is small then these pair is stored in some list, and we need to check for collision in every update. If the distance is big then we store after which update there can be a collision (it can be calculated because we know the distance and velocitites). It needs to be stored in some kind of priority queue. After previously calculated number of updates distance needs to be checked again and then we do the same procedure - put it on the list or again in the priority queue.

  • page wide bread crumb bar as at apple.com/store

    - by punkish
    I want to build a (don't know what to call it other than) bread crumb bar at the top of the page, kinda like at http://store.apple.com/us/browse/home/shop_mac/software, y'know, at the top of the page, the horizontal, light grey bar that looks like so [home icon] | Shop Mac | Mac Software Help | Account | Cart Actually, I've got that bar working, with a curved, square left edge, the intermediate chevrons, and the curved, square right edge. So, my bar looks like so [ Home > Foo > Bar > Baz ] I have little graphics fragments that make up the [ and the and the ] and the middle parts. The only problem is, I want the right edge to be at the right edge of my page. So, the above bar should look like so [ Home > Foo > Bar > Baz ] I want to have a variable number of entries in my bread crumb bar... so, I could have "Home, Foo, Bar, Baz" or I could have "Home, Foo" or "Home, Foo, Bar, Baz, Qux" and so on. In other words, I want the right edge of my bar to be dynamically long enough to extend to the edge of my web page. Suggestions?

  • Javascript redeclared global variable overrides old value

    - by Yousuf Haider
    I ran into an interesting issue the other day and was wondering if someone could shed light on why this is happening. Here is what I am doing (for the purposes of this example I have dumbed down the example somewhat): I am creating a globally scoped variable using the square bracket notation and assigning it a value. Later I declare a var with the same name as the one I just created above. Note I am not assigning a value. Since this is a redeclaration of the same variable the old value should not be overriden as described here: http://www.w3schools.com/js/js_variables.asp //create global variable with square bracket notation window['y'] = 'old'; //redeclaration of the same variable var y; if (!y) y = 'new'; alert(y); //shows New instead of Old The problem is that the old value actually does get overriden and in the above eg. the alert shows 'new' instead of 'old'. Why ? I guess another way to state my question is how is the above code different in terms of semantics from the code below: //create global variable var y = 'old'; //redeclaration of the same variable var y; if (!y) y = 'new'; alert(y); //shows Old

  • Foreach is crashing script, but no errors reported.

    - by ILMV
    So I've created this smarty function to get images from my flickr photostream using SimplePie... simple really, or so it should be. The problem I'm having is the foreach will crash the script, this doesn't happen if I put an exit after the closing foreach, of course because of this the rest of my script doesn't execute. The problem also completely subsides if I remove the foreach, I've tested it and it's not the contents of the foreach, but the loop itself. Error reporting is turned on but I don't get any, I also tried messing with the memory_limit, with no luck. Anyone know why this foreach is killing my script? Thanks! function smarty_function_flickr ($params, &$smarty) { require_once('system/library/SimplePie/simplepie.inc'); require_once('system/library/SimplePie/idn/idna_convert.class.php'); $flickr=new flickr(); /** * Set up SimplePie with all default values using shorthand syntax. */ $feed = new SimplePie($params['feed'], 'system/library/SimplePie/cache', '600'); $feed->handle_content_type(); /** * What sizes should we use? * Choices: square, thumb, small, medium, large. */ $thumb = 'square'; $full = 'medium'; $output = array(); $counter=0; // If I comment this foreach out the problem subsides, I know it is not the code within the foreach foreach ($feed->get_items() as $item) { $url = $flickr->image_from_description($item->get_description()); $output[$counter]['title'] = $item->get_title(); $output[$counter]['image'] = $flickr->select_image($url, $full); $output[$counter]['thumb'] = $flickr->select_image($url, $thumb); $counter++; } // Set template variables and template $smarty->assign('flickr',$output); $smarty->display('forms/'.$params['template'].'.tpl'); }

  • Game of life in F# with accelerator

    - by jpalmer
    I'm trying to write life in F# using accelerator v2, but for some odd reason my output isn't square despite all my arrays being square - It appears that everything but a rectangular area in the top left of the matrix is being set to false. I've got no idea how this could be happening as all my operations should treat the entire array equally. Any ideas? open Microsoft.ParallelArrays open System.Windows.Forms open System.Drawing type IPA = IntParallelArray type BPA = BoolParallelArray type PAops = ParallelArrays let RNG = new System.Random() let size = 1024 let arrinit i = Array2D.init size size (fun x y -> i) let target = new DX9Target() let threearr = new IPA(arrinit 3) let twoarr = new IPA(arrinit 2) let onearr = new IPA(arrinit 1) let zeroarr = new IPA(arrinit 0) let shifts = [|-1;-1|]::[|-1;0|]::[|-1;1|]::[|0;-1|]::[|0;1|]::[|1;-1|]::[|1;0|]::[|1;1|]::[] let progress (arr:BPA) = let sums = shifts //adds up whether a neighbor is on or not |> List.fold (fun (state:IPA) t ->PAops.Add(PAops.Cond(PAops.Rotate(arr,t),onearr,zeroarr),state)) zeroarr PAops.Or(PAops.CompareEqual(sums,threearr),PAops.And(PAops.CompareEqual(sums,twoarr),arr)) //rule for life let initrandom () = Array2D.init size size (fun x y -> if RNG.NextDouble() > 0.5 then true else false) type meform () as self= inherit Form() let mutable array = new BoolParallelArray(initrandom()) let timer = new System.Timers.Timer(1.0) //redrawing timer do base.DoubleBuffered <- true do base.Size <- Size(size,size) do timer.Elapsed.Add(fun _ -> self.Invalidate()) do timer.Start() let draw (t:Graphics) = array <- array |> progress let bmap = new System.Drawing.Bitmap(size,size) target.ToArray2D array |> Array2D.iteri (fun x y t -> if not t then bmap.SetPixel(x,y,Color.Black)) t.DrawImageUnscaled(bmap,0,0) do self.Paint.Add(fun t -> draw t.Graphics) do Application.Run(new meform())

  • what is the point of heterogenous arrays?

    - by aharon
    I know that more-dynamic-than-Java languages, like Python and Ruby, often allow you to place objects of mixed types in arrays, like so: ["hello", 120, ["world"]] What I don't understand is why you would ever use a feature like this. If I want to store heterogenous data in Java, I'll usually create an object for it. For example, say a User has int ID and String name. While I see that in Python/Ruby/PHP you could do something like this: [["John Smith", 000], ["Smith John", 001], ...] this seems a bit less safe/OO than creating a class User with attributes ID and name and then having your array: [<User: name="John Smith", id=000>, <User: name="Smith John", id=001>, ...] where those <User ...> things represent User objects. Is there reason to use the former over the latter in languages that support it? Or is there some bigger reason to use heterogenous arrays? N.B. I am not talking about arrays that include different objects that all implement the same interface or inherit from the same parent, e.g.: class Square extends Shape class Triangle extends Shape [new Square(), new Triangle()] because that is, to the programmer at least, still a homogenous array as you'll be doing the same thing with each shape (e.g., calling the draw() method), only the methods commonly defined between the two.

  • Redeclared javascript global variable overrides old value in IE

    - by Yousuf Haider
    (creating a separate question after comments on this: http://stackoverflow.com/questions/2634410/javascript-redeclared-global-variable-overrides-old-value) I am creating a globally scoped variable using the square bracket notation and assigning it a value inside an external js file. In another js file I declare a var with the same name as the one I just created above. Note I am not assigning a value. Since this is a redeclaration of the same variable the old value should not be overriden as described here: http://www.w3schools.com/js/js_variables.asp Create 2 javascript files with the following content : Script1 //create global variable with square bracket notation window['y'] = 'old'; Script2 //redeclaration of the same variable var y; if (!y) y = 'new'; alert(y); //shows New instead of Old in IE Include these 2 files in your html file <html> <head></head> <body> <script type="text/javascript" src="my.js"></script> <script type="text/javascript" src="my2.js"></script> </body> </html> Opening this page in Firefox and Chrome alerts 'old' which is the expected behavior. However in IE 8 the page will actually alert 'new' Any ideas on why this happens on IE ?
