• SEO effects of intermix of WP blog, custom PHP site and FB app game

  - by melbournetechlover

  We're a melbourne tech company in the process of building a custom site in PHP. We plan to launch a "pre-launch" page which is also custom coded (CSS3 on twitter bootstrap framework + HTML5 front end and PHP back end). On that site will be a link to a blog - the idea behind this is to build up ranking for a variety of relevant keywords prior to the full site going live (given the majority of the site is a member only community anyway so the blog is really the main way we'll be able to execute on-site SEO. Ideally, we would like to install wordpress in a subdirectory on our servers and just customise the header to look the same as the landing page of the website. But some questions and concerns... Is there any detrimental effect on SEO efforts in having two separate systems (one custom PHP, the other an installation of wordpress) to manage the blog vs the rest of the site? Are there any benefits or detriments to installing on a sub domain such as blog.sitename.com vs. sitename.com/blog. My preference would be sitename.com/blog as it feels neater - but open to suggestions based on knowledge of Google preferences. Separately, we are building a Facebook app which is under another site name. Again because we are launching this app first, from an SEO perspective, would it actually be better to run it from a sub domain on the main site - e.g. gamename.mainsitename.com instead of on app.gamename.com? Currently we have it on app.gamename.com, but if there are SEO benefits to moving it to the other domain and server then we'll do it. Basically we don't want to have our SEO efforts divided - will Google algorithms prefer two sites heavily referring traffic, or is it better to focus our efforts on one. I guess that's the crux of the issue. But the other one is - does Google care about traffic accessing a page built for the Facebook app iFrame - does that count toward rankings? Sorry I hope these questions aren't too complex - but we're in the tech world every day and still can't seem to find a good answer to these ones...hence I'm taking to the forums!! Free beer for whoever can give me a solid answer!

• One Year Oracle SocialChat - The Movie

  - by mprove

  Tweet | Like | Watch on Vimeo You’ve just watched – hopefully – my first short movie. Thank you! Here is a bit of the back stage story. About 6 weeks ago colleagues from SNBC (Social Network and Business Collaboration) announced a Social Use Case Competition. It was expected to submit a video of 2 to 5 minutes duration on the Social Enterprise (our internal phrase for Enterprise 2.0). Hmm – I had a few vague ideas, but no script – no actors – no experience in film making. Really the best conditions to try something! I chose our weekly SocialChats as my main topic. But if you don’t do Danish Dogma cinema, you still need a script. Hence I played around with the SocialChat’s archive, and all of a sudden a script and even the actors appeared in front of me. The words that you have just seen are weekly topics. Slightly abridged and rearranged to form a story. Exciting, next phase. How to get it on digital celluloid? I have to confess I am still impressed by epic. (Keep in mind, epic was done in 2004.) And my actors – words – call for a typographic style already. The main part was done over a weekend with Apple Keynote. And I even found a wonderful matching soundtrack among my albums: Didge Goes World by Delago. I picked parts of Second Day and Seventh Day. Literally, the rhythm was set, and I "just" had to complete the movie. Tools used – apart from trial and error: Keynote, Pixelmator, GarageBand, iMovie. Finally I want to mention that I am extremely thankful to BSC Music for granting permissions to use the tracks for this short film! Without this sound it would have been just an ordinary slide show. – Internal note: The next SocialChat is on Death by PowerPoint vs. Presentation Zen. CU this Friday 3pm Greenwich / 7am Pacific.

• Smooth animation on a persistently refreshing canvas

  - by Neurofluxation

  Yo everyone! I have been working on an Isometric Tile Game Engine in HTML5/Canvas for a little while now and I have a complete working game. Earlier today I looked back over my code and thought: "hmm, let's try to get this animated smoothly..." And since then, that is all I have tried to do. The problem I would like the character to actually "slide" from tile to tile - but the canvas redrawing doesn't allow this - does anyone have any ideas....? Code and fiddle below...

• following a moving sprite

  - by iQue

  Im trying to get my enemies to follow my main-character of the game (2D), but for some reason the game starts lagging like crazy when I do it the way I want to do it, and the following-part dosnt work 100% either, its just 1/24 enemies that comes to my sprite, the other 23 move towards it but stay at a certain point. Might be a poor explenation but dont know how else to put it. Code for moving my enemies: private int enemyX(){ int x = 0; for (int i = 0; i < enemies.size(); i++){ if (controls.pointerPosition.x > enemies.get(i).getX()){//pointerPosition is the position of my main-sprite. x = 5; } else{ x=-5; } Log.d(TAG, "happyX HERE: " + controls.pointerPosition.x); Log.d(TAG, "enemyX HERE: " + enemies.get(i).getX()); } return x; } private int enemyY(){ int y = 0; for (int i = 0; i < enemies.size(); i++){ if (controls.pointerPosition.y > enemies.get(i).getY()){ y = 5; } else{ y=-5; } } return y; } I send it to the update-method in my Enemy-class: private void drawEnemy(Canvas canvas){ addEnemies(); // a method where I add enemies to my arrayList, no parameters except bitmap. for(int i = 0; i < enemies.size(); i++){ enemies.get(i).update(enemyX(), enemyY()); } for(int i = 0; i < enemies.size(); i++){ enemies.get(i).draw(canvas); } } and finally, the update-method itself, located in my Enemy-class: public void update(int velX, int velY) { x += velX; //sets x before I draw y += velY; //sets y before I draw currentFrame = ++currentFrame % BMP_COLUMNS; } So can any1 figure out why it starts lagging so much and how I can fix it? Thanks for your time!

• Can I get a C++ Compiler to instantiate objects at compile time

  - by gam3

  I am writing some code that has a very large number of reasonably simple objects and I would like them the be created at compile time. I would think that a compiler would be able to do this, but I have not been able to figure out how. In C I could do the the following: #include <stdio.h> typedef struct data_s { int a; int b; char *c; } info; info list[] = { 1, 2, "a", 3, 4, "b", }; main() { int i; for (i = 0; i < sizeof(list)/sizeof(*list); i++) { printf("%d %s\n", i, list[i].c); } } Using #C++* each object has it constructor called rather than just being layed out in memory. #include <iostream> using std::cout; using std::endl; class Info { const int a; const int b; const char *c; public: Info(const int, const int, const char *); const int get_a() { return a; }; const int get_b() { return b; }; const char *get_c() const { return c; }; }; Info::Info(const int a, const int b, const char *c) : a(a), b(b), c(c) {}; Info list[] = { Info(1, 2, "a"), Info(3, 4, "b"), }; main() { for (int i = 0; i < sizeof(list)/sizeof(*list); i++) { cout << i << " " << list[i].get_c() << endl; } } I just don't see what information is not available for the compiler to completely instantiate these objects at compile time, so I assume I am missing something.

• Fixing a NoClassDefFoundError

  - by Chris Okyen

  I have some code: package ftc; import java.util.Scanner; public class Fer_To_Cel { public static void main(String[] argv) { // Scanner object to get the temp in degrees Farenheit Scanner keyboard = new Scanner(System.in); boolean isInt = true; // temporarily put as true in case the user enters a valid int the first time int degreesF = 0; // initialy set to 0 do { try { // Input the temperature text. System.out.print("\nPlease enter a temperature (integer number, no fractional part) in degrees Farenheit: "); degreesF = Integer.parseInt(keyboard.next()); // Get user input and Assign the far. temperature variable, which is casted from String to int. } // Let the user know in a user friendly notice that the value entered wasnt an int ( give int value range ) , and then give error log catch(java.lang.Exception e) { System.out.println("Sorry but you entered a non-int value ( needs to be between ( including ) -2,147,483,648 and 2,147,483,647 ).. \n"); e.printStackTrace(); isInt = false; } } while(!isInt); System.out.println(""); // print a new line. final int degreesC = (5*(degreesF-32)/9); // convert the degrees from F to C and store the resulting expression in degreesC // Print out a newline, then print what X degrees F is in Celcius. System.out.println("\n" + degreesF + " degrees Farenheit is " + degreesC + " degrees Celcius"); } } And The following error: C:\Program Files\Java\jdk1.7.0_06\bin>java Fer_To_Cel Exception in thread "main" java.lang.NoClassDefFoundError: Fer_To_Cel (wrong name: ftc/Fer_To_Cel) at java.lang.ClassLoader.defineClass1(Native Method) at java.lang.ClassLoader.defineClass(ClassLoader.java:791) at java.security.SecureClassLoader.defineClass(SecureClassLoader.java:14 at java.net.URLClassLoader.defineClass(URLClassLoader.java:449) at java.net.URLClassLoader.access$100(URLClassLoader.java:71) at java.net.URLClassLoader$1.run(URLClassLoader.java:361) at java.net.URLClassLoader$1.run(URLClassLoader.java:355) at java.security.AccessController.doPrivileged(Native Method) at java.net.URLClassLoader.findClass(URLClassLoader.java:354) at java.lang.ClassLoader.loadClass(ClassLoader.java:423) at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:308) at java.lang.ClassLoader.loadClass(ClassLoader.java:356) at sun.launcher.LauncherHelper.checkAndLoadMain(LauncherHelper.java:480) The code compiled without compile errors, but presented errors during execution. Which leads me to two questions. I know Errors can be termed Compiler, Runtime and Logic Errors, but the NoClassDefFoundError inherits java.lang.LinkageError. Does that make it a Linker error, being niether of the three types of errors I listed, If I am right this is the answer. For someone else who obtains the singular .java file and compiles it, would this be the only way to solve this problem? Or can I (should I ) do/have done something to fix this problem? Basically, based on a basis of programming, is this a fault of me as the writer? Could this be done once on, my half and be distributed and not needed be done again?

• Handling bugs, quirks, or annoyances in vendor-supplied headers

  - by supercat

  If the header file supplied by a vendor of something with whom one's code must interact is deficient in some way, in what cases is it better to: Work around the header's deficiencies in the main code Copy the header file to the local project and fix it Fix the header file in the spot where it's stored as a vendor-supplied tool Fix the header file in the central spot, but also make a local copy and try to always have the two match Do something else As an example, the header file supplied by ST Micro for the STM320LF series contains the lines: typedef struct { __IO uint32_t MODER; __IO uint16_t OTYPER; uint16_t RESERVED0; .... __IO uint16_t BSRRL; /* BSRR register is split to 2 * 16-bit fields BSRRL */ __IO uint16_t BSRRH; /* BSRR register is split to 2 * 16-bit fields BSRRH */ .... } GPIO_TypeDef; In the hardware, and in the hardware documentation, BSRR is described as a single 32-bit register. About 98% of the time one wants to write to BSRR, one will only be interested in writing the upper half or the lower half; it is thus convenient to be able to use BSSRH and BSSRL as a means of writing half the register. On the other hand, there are occasions when it is necessary that the entire 32-bit register be written as a single atomic operation. The "optimal" way to write it (setting aside white-spacing issues) would be: typedef struct { __IO uint32_t MODER; __IO uint16_t OTYPER; uint16_t RESERVED0; .... union // Allow BSRR access as 32-bit register or two 16-bit registers { __IO uint32_t BSRR; // 32-bit BSSR register as a whole struct { __IO uint16_t BSRRL, BSRRH; };// Two 16-bit parts }; .... } GPIO_TypeDef; If the struct were defined that way, code could use BSRR when necessary to write all 32 bits, or BSRRH/BSRRL when writing 16 bits. Given that the header isn't that way, would better practice be to use the header as-is, but apply an icky typecast in the main code writing what would be idiomatically written as thePort->BSRR = 0x12345678; as *((uint32_t)&(thePort->BSSRH)) = 0x12345678;, or would be be better to use a patched header file? If the latter, where should the patched file me stored and how should it be managed?

• C Minishell Command Expansion Printing Gibberish

  - by Optimus_Pwn

  I'm writing a unix minishell in C, and am at the point where I'm adding command expansion. What I mean by this is that I can nest commands in other commands, for example: $> echo hello $(echo world! ... $(echo and stuff)) hello world! ... and stuff I think I have it working mostly, however it isn't marking the end of the expanded string correctly, for example if I do: $> echo a $(echo b $(echo c)) a b c $> echo d $(echo e) d e c See it prints the c, even though I didn't ask it to. Here is my code: msh.c - http://pastebin.com/sd6DZYwB expand.c - http://pastebin.com/uLqvFGPw I have a more code, but there's a lot of it, and these are the parts that I'm having trouble with at the moment. I'll try to tell you the basic way I'm doing this. Main is in msh.c, here it gets a line of input from either the commandline or a shellfile, and then calls processline (char *line, int outFD, int waitFlag), where line is the line we just got, outFD is the file descriptor of the output file, and waitFlag tells us whether or not we should wait if we fork. When we call this from main we do it like this: processline (buffer, 1, 1); In processline, we allocate a new line: char expanded_line[EXPANDEDLEN]; We then call expand, in expand.c: expand(line, expanded_line, EXPANDEDLEN); In expand, we copy the characters literally from line to expanded_line until we find a $(, which then calls: static int expCmdOutput(char *orig, char *new, int *oldl_ind, int *newl_ind) orig is line, and new is expanded line. oldl_ind and newl_ind are the current positions in the line and expanded line, respectively. Then we pipe, and recursively call processline, passing it the nested command(for example, if we had "echo a $(echo b)", we would pass processline "echo b"). This is where I get confused, each time expand is called, is it allocating a new chunk of memory EXPANDEDLEN long? If so, this is bad because I'll run out of stack room really quickly(in the case of a hugely nested commandline input). In expand I insert a null character at the end of the expanded string, so why is it printing past it? If you guys need any more code, or explanations, just ask. Secondly, I put the code in pastebin because there's a ton of it, and in my experience people don't like it when I fill up several pages with code. Thanks.

• Transferring ratings and playlists from Rhythmbox to Clementine

  After the latest update, Rhythmbox (which was my main mp3 player on my Ubuntu Latest distro) stopped functioning: it dies just after startup. So, I turned to Clementine which I like a lot. However in Rhythmbox I had my playlists and ratings. Song ratings are very important to me because many of my auto-playlists are depending on them. Is there anyway I can get my playlists and ratings from Rhythmbox and add them to Clementine? Thanks.

• Bump mapping Problem GLSL

  I am having a slight problem with my Bump Mapping project. Although everything works OK (at least from what I know) there is a slight mistake somewhere and I get incorrect shading on the brick wall when the light goes to the one side or the other as seen in the picture below: The light is on the right side so the shading on the wall should be the other way. I have provided the shaders to help find the issue (I do not have much experience with shaders). Shaders: varying vec3 viewVec; varying vec3 position; varying vec3 lightvec; attribute vec3 tangent; attribute vec3 binormal; uniform vec3 lightpos; uniform mat4 cameraMat; void main() { gl_TexCoord[0] = gl_MultiTexCoord0; gl_Position = ftransform(); position = vec3(gl_ModelViewMatrix * gl_Vertex); lightvec = vec3(cameraMat * vec4(lightpos,1.0)) - position ; vec3 eyeVec = vec3(gl_ModelViewMatrix * gl_Vertex); viewVec = normalize(-eyeVec); } uniform sampler2D colormap; uniform sampler2D normalmap; varying vec3 viewVec; varying vec3 position; varying vec3 lightvec; vec3 vv; uniform float diffuset; uniform float specularterm; uniform float ambientterm; void main() { vv=viewVec; vec3 normals = normalize(texture2D(normalmap,gl_TexCoord[0].st).rgb * 2.0 - 1.0); normals.y = -normals.y; //normals = (normals * gl_NormalMatrix).xyz ; vec3 distance = lightvec; float dist_number =length(distance); float final_dist_number = 2.0/pow(dist_number,diffuset); vec3 light_dir=normalize(lightvec); vec3 Halfvector = normalize(light_dir+vv); float angle=max(dot(Halfvector,normals),0.0); angle= pow(angle,specularterm); vec3 specular=vec3(angle,angle,angle); float diffuseterm=max(dot(light_dir,normals),0.0); vec3 diffuse = diffuseterm * texture2D(colormap,gl_TexCoord[0].st).rgb; vec3 ambient = ambientterm *texture2D(colormap,gl_TexCoord[0].st).rgb; vec3 diffusefinal = diffuse * final_dist_number; vec3 finalcolor=diffusefinal+specular+ambient; gl_FragColor = vec4(finalcolor, 1.0); }

• Aggregating customer service emails from multiple ecommerce sites for easy handling

  - by nitbuntu

  For one of my main customer help email addresses I use Mozilla Thunderbird with a combination of tags and saved searches. As the number of my e-commerce sites grows from 1 to more, customer service handling gets more tricky. Is there any simple and efficient way of handling emails from the different sites? Perhaps what I'm looking for is a way of aggregating customer service emails from different sites, into one place? Perhaps there's a way of already doing this within Thunderbird or Gmail?

• Is there any software to clip a website, make changes to the code and republish it?

  - by user1445919

  I am working in the front end of an application and we provide the interface between the customers and several backend services. We have been using Kapow software to clip the html/jsp code we receive from the backend, make the necessary changes and publish them on the main website. I wanted to know if there is any other alternative to this software which suffices our requirement. Also, are any of those open source?

• How should I structure my turn based engine to allow flexibility for players/AI and observation?

  - by Reefpirate

  I've just started making a Turn Based Strategy engine in GameMaker's GML language... And I was cruising along nicely until it came time to handle the turn cycle, and determining who is controlling what player, and also how to handle the camera and what is displayed on screen. Here's an outline of the main switch happening in my main game loop at the moment: switch (GameState) { case BEGIN_TURN: // Start of turn operations/routines break; case MID_TURN: switch (PControlledBy[Turn]) { case HUMAN: switch (MidTurnState) { case MT_SELECT: // No units selected, 'idle' UI state break; case MT_MOVE: // Unit selected and attempting to move break; case MT_ATTACK: break; } break; case COMPUTER: // AI ROUTINES GO HERE break; case OBSERVER: // OBSERVER ROUTINES GO HERE break; } break; case END_TURN: // End of turn routines/operations, and move Turn to next player break; } Now, I can see a couple of problems with this set-up already... But I don't have any idea how to go about making it 'right'. Turn is a global variable that stores which player's turn it is, and the BEGIN_TURN and END_TURN states make perfect sense to me... But the MID_TURN state is baffling me because of the things I want to happen here: If there are players controlled by humans, I want the AI to do it's thing on its turn here, but I want to be able to have the camera follow the AI as it makes moves in the human player's vision. If there are no human controlled player's, I'd like to be able to watch two or more AI's battle it out on the map with god-like 'observer' vision. So basically I'm wondering if there are any resources for how to structure a Turn Based Strategy engine? I've found lots of writing about pathfinding and AI, and those are all great... But when it comes to handling the turn structure and the game states I am having trouble finding any resources at all. How should the states be divided to allow flexibility between the players and the controllers (HUMAN, COMPUTER, OBSERVER)? Also, maybe if I'm on the right track I just need some reassurance before I lay down another few hundred lines of code...

• ubuntu lite volume control

  - by idio

  i've recently gave up on the main ubuntu, especially since new updates ruined Quantal and Raring is just a mess and went on to install a more friendly version: Ubuntu Lite. while i am quite happy with most functionalities of this lite version of 12.04, one of the modifications volume control is totally ridiculos, there is an applet that is completely counter-intutitive. So my question is: is there a way to install back the ubuntu classic volume control so i can let go of this applet alltogether? thanx

• How to edit gnome/unity menus without using Alacarte?

  - by Vagrant232

  Alacarte crashes every time I attempt to edit a submenu or move an item from one submenu to another and then I'd have to wipe the application.menu files or my gnomeshell desktop would be useless. Is there a way to organize my main menu and unity dash applications subcategories without using Alacarte? I've got so many items installed in the wrong category and I'd also like to remove a ton of zombie icons.
