  • how to uninstall sphinx server

    - by misterjinx
    I installed (from sources) yesterday sphinx server and didn't think of configuring it properly, so I left the default installation directory (/usr/local). Today I realized that it created all of it's directories inside that directory, instead of creating its own (as I wrongly thought). So today I started again the installation and specified explicitly the location where to install. After that I removed the previous directories from /usr/local that were created when the first installation was done (bin, etc, var). So I thought of giving it a test. I created the .conf file and wanted to run the indexer. But now, the indexer always tries to search the .conf file in the old location (obviously does not find anything) and when I specify where to find the .conf file it gives me errors for each of the configuration settings present. I know I did something wrong when I deleted manually those files and that's why I'm asking you if have any ideas how to correctly uninstall sphinx. Thank you.

  • Matching my skills with Java and Web Programming

    - by John R
    here is my main question: What is the most common way that Java is used in web development? The reason I ask: I am currently in the process of finding my first internship. Every employer has a separate set of languages, technologies and acronyms they want their candidates to know. In school I did well with Java. As a hobby and interest I have developed a handful of web pages widgets, scripts, etc. My university emphasized Java, C and theory. My hobbies emphasize HTML, PHP, JavaScript, CSS, and a little jQuery, etc. I can't learn a dozen different technologies to satisfy most prospective employers (in what is left of the summer). I think my best bet is combine my skills with Java and my interests in web development. That brings me back to my original question: What is the most common way that Java is used in web development?

  • window title bar and controls (minimize, maximize and close) don't work sometimes

    - by Ravindranath
    I am using Ubuntu 11.10. Sometimes the window controls don't work. If I click on any of the icons on top-right or top-left they just become colorless and fade away, as though that are not present. The window has not frozen, as I can click inside the window and continue to work with it. The moment I click inside the window the titlebar controls regain their color, but when I click them again, they fade and bcm colorless. As a result, I cannot close, minimize or maximize. This is not a continuous problem, but happens very frequently.

  • Avoiding coupling

    - by Seralize
    It is also true that a system may become so coupled, where each class is dependent on other classes that depend on other classes, that it is no longer possible to make a change in one place without having a ripple effect and having to make subsequent changes in many places.[1] This is why using an interface or an abstract class can be valuable in any object-oriented software project. Quote from Wikipedia Starting from scratch I'm starting from scratch with a project that I recently finished because I found the code to be too tightly coupled and hard to refactor, even when using MVC. I will be using MVC on my new project aswell but want to try and avoid the pitfalls this time, hopefully with your help. Project summary My issue is that I really wish to keep the Controller as clean as possible, but it seems like I can't do this. The basic idea of the program is that the user picks wordlists which is sent to the game engine. It will pick random words from the lists until there are none left. Problem at hand My main problem is that the game will have 'modes', and need to check the input in different ways through a method called checkWord(), but exactly where to put this and how to abstract it properly is a challenge to me. I'm new to design patterns, so not sure whether there exist any might fit my problem. My own attempt at abstraction Here is what I've gotten so far after hours of 'refactoring' the design plans, and I know it's long, but it's the best I could do to try and give you an overview (Note: As this is the sketch, anything is subject to change, all help and advice is very welcome. Also note the marked coupling points): Wordlist class Wordlist { // Basic CRUD etc. here! // Other sample methods: public function wordlistCount($user_id) {} // Returns count of how many wordlists a user has public function getAll($user_id) {} // Returns all wordlists of a user } Word class Word { // Basic CRUD etc. here! // Other sample methods: public function wordCount($wordlist_id) {} // Returns count of words in a wordlist public function getAll($wordlist_id) {} // Returns all words from a wordlist public function getWordInfo($word_id) {} // Returns information about a word } Wordpicker class Wordpicker { // The class needs to know which words and wordlists to exclude protected $_used_words = array(); protected $_used_wordlists = array(); // Wordlists to pick words from protected $_wordlists = array(); /* Public Methods */ public function setWordlists($wordlists = array()) {} public function setUsedWords($used_words = array()) {} public function setUsedWordlists($used_wordlists = array()) {} public function getRandomWord() {} // COUPLING POINT! Will most likely need to communicate with both the Wordlist and Word classes /* Protected Methods */ protected function _checkAvailableWordlists() {} // COUPLING POINT! Might need to check if wordlists are deleted etc. protected function _checkAvailableWords() {} // COUPLING POINT! Method needs to get all words in a wordlist from the Word class } Game class Game { protected $_session_id; // The ID of a game session which gets stored in the database along with game details protected $_game_info = array(); // Game instantiation public function __construct($user_id) { if (! $this->_session_id = $this->_gameExists($user_id)) { // New game } else { // Resume game } } // This is the method I tried to make flexible by using abstract classes etc. // Does it even belong in this class at all? public function checkWord($answer, $native_word, $translation) {} // This method checks the answer against the native word / translation word, depending on game mode public function getGameInfo() {} // Returns information about a game session, or creates it if it does not exist public function deleteSession($session_id) {} // Deletes a game session from the database // Methods dealing with game session information protected function _gameExists($user_id) {} protected function _getProgress($session_id) {} protected function _updateProgress($game_info = array()) {} } The Game /* CONTROLLER */ /* "Guess the word" page */ // User input $game_type = $_POST['game_type']; // Chosen with radio buttons etc. $wordlists = $_POST['wordlists']; // Chosen with checkboxes etc. // Starts a new game or resumes one from the database $game = new Game($_SESSION['user_id']); $game_info = $game->getGameInfo(); // Instantiates a new Wordpicker $wordpicker = new Wordpicker(); $wordpicker->setWordlists((isset($game_info['wordlists'])) ? $game_info['wordlists'] : $wordlists); $wordpicker->setUsedWordlists((isset($game_info['used_wordlists'])) ? $game_info['used_wordlists'] : NULL); $wordpicker->setUsedWords((isset($game_info['used_words'])) ? $game_info['used_words'] : NULL); // Fetches an available word if (! $word_id = $wordpicker->getRandomWord()) { // No more words left - game over! $game->deleteSession($game_info['id']); redirect(); } else { // Presents word details to the user $word = new Word(); $word_info = $word->getWordInfo($word_id); } The Bit to Finish /* CONTROLLER */ /* "Check the answer" page */ // ?????????????????? ( http://pastebin.com/cc6MtLTR ) Make sure you toggle the 'Layout Width' to the right for a better view. Thanks in advance. Questions To which extent should objects be loosely coupled? If object A needs info from object B, how is it supposed to get this without losing too much cohesion? As suggested in the comments, models should hold all business logic. However, as objects should be independent, where to glue them together? Should the model contain some sort of "index" or "client" area which connects the dots? Edit: So basically what I should do for a start is to make a new model which I can more easily call with oneliners such as $model->doAction(); // Lots of code in here which uses classes! How about the method for checking words? Should it be it's own object? I'm not sure where I should put it as it's pretty much part of the 'game'. But on another hand, I could just leave out the 'abstraction and OOPness' and make it a method of the 'client model' which will be encapsulated from the controller anyway. Very unsure about this.

  • the window of calender is out of the screen

    - by draw
    hi, I've been using a external 21.5' monitor for my laptop of 12.1' monitor, and moved my top panel to the right and add a new panel to the bottom edge of the screen. A screenshot of the right part of my desktop is here: http://i.imgur.com/kOHwT.png As you see, The window of the calender is out of the screen. The alt+left mouse button did not work. How do you move the calender window? update: I managed to come up with a solution to get the window or panel of cal in the screen. Just remove the panel of clock and re-add it. But unfortunately, the preferences are lost. You have to reset the preferences, such as locations... but after re-adding 2 locations, the window of cal panel was just shown as the same of the previous screenshot before.

  • Kill Android Apps without Task Manager

    - by Gopinath
    Android is for geeks. It best fits for the users who know how to get around sloppy areas and find their way out. If you are an heavy Android user you would have noticed Apps crashing often. A well written App should not crash, if crashes should exit the process gracefully. But unfortunately Google Play has many apps that not only just crash, they hang in a where they don’t respond and you can’t access the application. The only option left to you is to forcefully close them. If you encounter a situation to forcefully close an App you have two options. First one is to use Task Manager application to close them and the second option is use built in Android OS features. Here are the steps to forcefully close an Android App without using Task Manager Step 1: Go to Settings and select Apps Step 2: Switch to All apps tab and select the application you want to close Step 3: Touch on Force Stop button to forcefully close the app That’s the simplest way to forcefully kill Android Apps.

  • Stuck on Ubuntu Startup Screen

    - by Pietro
    Since yesterday, my system won't get past the startup screen (the Ubuntu logo with the blinking red dots). I left it for over an hour and didn't get the login screen. It was working normally before that and I don't recall any changes (no new software, etc). I can login through the terminal with ALT+F1 but I don't know what to do to get the graphic mode. The command startx fails. I'm running Ubuntu 12.10 64 bits on a Core I5 with Intel motherboard. No video card or sound card.

  • How to fix Fullscreen focus error in Unity?

    - by Vagrant232
    Recently, I've been experiencing an error with programs that have a fullscreen mode with low resolution (80xx600 and below) in Unity. The problem isn't valid in gnomeshell. Whenever I launch an application, unity would enlarge the screen more than it should be and would only show me the upper left corner of the screen (I only see a magnified quarter of the screen). At first I thought that it was an issue related to wine but I later found out that native applications (such as world of goo) are affected as well. Apps that taken on the full screen but have a larger resolution don't face such an issue. Is it possible to get this fixed manually? Or do I have to wait for updates?

  • "Time Control" in a 2d Platformer

    - by Woody Zantzinger
    I am making a 2d platformer where the player can press a button, and restart the level, only their previous character will also run the level at the same time, like they are traveling back in time. I know other games have done this before, and the way I have thought of doing it is to make the game character have a set of actions (Idle, Jumping, Walking Left etc.) and then detect changes in those actions and log them into a list along with the game time. So then when I need the character to run the level again on its own, I can just go through the list changing its actions at the right time. Is this the best way to do it? Does anyone have any experience in this? Thanks.

  • Detect Open Space in Farseer

    - by Tom G
    I'm working on a 2D platformer using XNA and Farseer. I would like the player's character to be able to grab and climb up ledges. Detecting a collision between the player and the side of a wall is simple enough with the OnCollision delegate, but I have to admit I'm a bit stumped on how to detect that there's enough clearance for the PC to mount the ledge. Essentially, I want to ensure there's an appropriately sized rectangle above and to the left or right of the PC (depending on their direction) and I'm not sure how I would check for such a space. Any suggestions on how to determine there is nothing in the simulated world within some bounding rectangle?

  • Window controls missing; Cannot maximise or minimize applications

    - by omg_scout
    Ubuntu 12.10 32 bits, fresh installation. How can I make Unity maximize or minimize a window? I see no button,option, anything, do I miss something big? Quick googling did not give me a piece of answer, too: On first screen, I have a terminal window. Only clue about maximizing it I found was pressing F11 which made it fullscreen, hiding left bar as well. I would prefer it to take whole free space instead of whole screen. How can I do that? On second screen, I have an opera browser which takes bigger part of the screen but I can't make it take whole screen. Restarting opera did not work. How do I minimize/maximize apps? Also, in case I would like to see the desktop, only solution I found was closing everything Help guys. I kind of like new GUI, but I can't have simplest tasks done there, I feel like I miss something big there.

  • 'Situations gone wrong' for web apps...

    - by AvgJoe007
    Hi all I know there's some decent material floating around relating to more specific areas, but wanted to get some opinions from people who have had bad experiences in the past. I have a project where I can have a say on the design of a B2C web app, which has some external API interfaces. UX is crucial as is speed. Not sure what technology will be used at this stage. In designing this application, I want to make sure obvious features are not left out (i.e. ones that make maintenance/development easier). So can you guys tell me about 'situations gone wrong' that could have been avoided had more consideration taken place? Am looking to gather feedback in general, so don't worry if your example is industry/technology specific - so long as it pertains to web. Thanks for reading, I look forward to your responses!

  • How can I always show the close, minimise and maximise buttons on their windows and keep global menus?

    - by sup
    First, this is not a duplicate of How can I always show the close, minimise & maximise buttons into their own windows? - I would like to preserve global menus. Is there a way to only always show the close, minimise and maximise buttons on every application? The use case is as follows: I have a maximized application in the background, over it is a not-maximized application that has got focus. I want to close the maximized application. I move the pointer to upper left corner. The buttons do not show, since the background application does not have focus. I have to go back, click on it and then go back to the corner to close it. I do that several times a day :-( .

  • How to avoid circular dependencies between Player and World?

    - by futlib
    I'm working on a 2D game where you can move up, down, left and right. I have essentially two game logic objects: Player: Has a position relative to the world World: Draws the map and the player So far, World depends on Player (i.e. has a reference to it), needing its position to figure out where to draw the player character, and which portion of the map to draw. Now I want to add collision detection to make it impossible for the player to move through walls. The simplest way I can think of is to have the Player ask the World if the intended movement is possible. But that would introduce a circular dependency between Player and World (i.e. each holds a reference to the other), which seems worth avoiding. The only way I came up with is to have the World move the Player, but I find that somewhat unintuitive. What is my best option? Or is avoiding a circular dependency not worth it?

  • return to middle click copy and paste ubuntu 13.10

    - by user206999
    Recent update to 13.10 left the middle mouse button turning sound on and off!! How do I get back to being able to copy and paste? Select the text then paste with the middle Wheel mouse button. This is a feature I used to use a lot and I find extremely quick and useful. I know I can use ctrl c, ctrl v, and right click select copy, select paste but this is clunky compared to just being able to click the middle wheel button. Is there a settings menu option to gain correct operation of the middle wheel button?

  • Waiting for Windows 8: A Long, Hot Summer

    - by andrewbrust
    Microsoft has revealed some things about Windows 8, and revealed a part of the developer story for new Windows 8 “tailored,” “immersive” applications.  In retrospect, very little was shared.  The bit that was revealed to us is that those applications can be developed using a combination of HTML 5 and JavaScript.  Not much else was said, except that additional details would be revealed at Microsoft’s //Build/ conference in Anaheim, California in September. This has left a lot of people in suspense, and it seems that suspended state is going to last all summer.  The problem, of course, is that in the absence of hard information, people fill the void with Speculation, Rumor and Gloom.  That’s a bit like Fear, Uncertainty and Doubt, except that it’s self-imposed by the Microsoft community and not planted by Microsoft’s competitors. This is a less-than-perfect situation.  Not only is it causing developers to worry about the value of their skill sets, but I am already hearing from consulting shops that customers are getting nervous too and, in extreme cases, opting for non-Microsoft tools for their projects as a result.  I’m also hearing from dev tool ISVs that sales have suffered as a result. It’s quite possible that the customers moving off .NET wanted to do so anyway and it’s also possible that dev tool ISVs are suffering slower sales this year due a slowed rate of economic recovery. Without hard information, tend to people interpret things negatively.  Actually, that’s the major point in all of this. While there is multitude of opinions about what the Windows 8 development platform will look like once fully revealed, there is an emerging consensus around one thing: it sure would help if Microsoft revealed more of its strategy…just enough to quash absurd rumors, stabilize the .NET ecosystem and get people to stay calm. We’ve had some reassurances thus far: there will be a Windows desktop mode; we’ll still have Windows Explorer, we’ll still run Office, we’ll still have a task bar, and all the skills and tools we use now will still work there.  But with reassurances like that…people still feel insecure.  Because telling us that Windows 8 will have what is essentially a “classic” mode sure makes it sound like today’s skill sets will soon be “classic” too…and then maybe they’ll just become obsolete. Humans find change scary; it’s natural.  And when left alone with their fears – because no one is saying anything to dispel them – people can go from frightened to paranoid, and can start to viewing things in a downright conspiratorial light.  It would be great if Microsoft stepped into the void now and told us what is coming – especially because whatever they tell us is bound to be at least a little better than what people think they are going to hear. I don’t know what the announcements will be, but I do have it on authority, from a number of sources, that Microsoft isn’t gong to talk until //Build/.  That means no news until September September 13th.  Nothing until after Labor Day.  You get zippo until after the Back-to-School sales are done. What to do?  Try not to let the dark voices of gloom and doom fill your head.  Even in the absence of answers, we still have some important facts: The .NET developer community is huge. Microsoft’s customers have major investments in .NET, and in .NET skills. Political infighting in Redmond might make for irrational decisions, but ultimately public companies can’t just alienate their advocates and piss off their customers.  Spite doesn’t trump fiduciary responsibility. The computing device markets are changing, software is changing, software business models are changing and developers are changing.  Microsoft has to keep up. The HTML + JavaScript community is huge too, and it includes many of the “changed” developers. Public companies can’t ignore new markets nor the popular standards that can help them enter those new markets.  Loyalty doesn’t trump fiduciary responsibility either. If Microsoft can appeal to new developers, then it should. If Microsoft can keep catering to its existing developers and customers -- not just through legacy support, but also through empowering futures -- then it probably will. You don’t have to shove your old friends out into the rain to make room for new ones; you can bring those new constituents in under a bigger tent.  I hope Microsoft will enlarge the tent, and I have trouble imagining why it would not.

  • Dell M6800 with Windos 8.1 on part-1, cannot run if Ubuntu and Fedora are 2nd and 3rd OSsen?

    - by user289334
    On a Dell M6800 machine that has Windows 8 pre-installed, I upgraded to 8.1, then I loaded Ubuntu 14.04 then Fedora 20 the only way I could, that is in "Legacy" BIOS Mode. BTW the Ubuntu install was unable to complete but Fedora did, and left all working, 2 bootable OSsen, with Grub2 from Fedora doing the boots, but Windows 8.1 is now "invisible". I have run Boot-Repair but info is not useful. It tells me to switch to UEFI which, on M6800, doesn't work with this (too long-winded to explain why here). I need to have the Grub2 configs "see" the original Windows 8.1 partition, with BIOS switched to "Legacy". BTW various posts have said make switch to UEFI to boot from, say, USB-stick or DVD; this is wrong, you can't - UEFI mode only allows boot from the Windows partition, which it says has a Windows 8.1 on it, which doesn't boot. Basically, if you have actually succeeded in loading Ubuntu 14.04 or Fedora 20 on an M6800, which comes with pre-loaded Windows 8, you will know how I fix this.

  • Do wordpress websites get indexed quicker by SE than a regular website?

    - by guisasso
    I registered a couple of domains with the names of categories of products we sell. I then installed wordpress in one of those domains and played around with it for a bit, and left it alone for about a month. There was a link on my regular website to that secondary website and that website was also registered in google's webmaster tools, but that's that. I then searched on google last week for that product category, and to my surprise, that secondary website showed up in the 2nd or 3rd page on google. Now my question is: Do search engines index wordpress websites quicker? I had given up on using wordpress for that website, since it's so simple, but should i use it, would it give me better results? Thanks in advance for the help, if the question is not deleted.

  • How do I multiply pixels on an SDL Surface?

    - by NoobScratcher
    Okay so I'm able to put blank pixels into a surface and also draw gradient pixels rectangles,etc But I don't know how to multiply the pixels on a surface so I was hoping someone could provide me information on this topic. I was thinking you could get the members pixel and then * it by 2 but that didn't provide results I wanted so I'm now thinking that you have to actually get to the position in bytes in one location to the left and one location to the right and then store it in memory and then * that by 2 am I correct or what? If so what is it that allows me to do that and how do I do that?

  • How do I convert matrices intended for OpenGL to be compatible for DirectX?

    - by gardian06
    I have finished working through the book "Game Physics Engine Development 2nd Ed" by Millington, and have got it working, but I want to adapt it to work with DirectX. I understand that D3D9+ has the option to use either left handed, or right handed convention, but I am unsure about how to return my matrices to be usable by D3D. The source code gives returning OpenGL column major matrices (the transpose of the working transform matrix shown below), but DirectX is row major. For those unfamiliar for the organization of the matrices used in the book: [r11 r12 r13 t1] [r21 r22 r23 t2] [r31 r32 r33 t3] [ 0 0 0 1] r## meaning the value of that element in the rotation matrix, and t# meaning the translation value. So the question in short is: How do I convert the matrix above to be easily usable by D3D? All of the documentation that I have found simply states that D3D is row major, but not where to put what elements so that it is usable by D3D in terms of rotation, and translation elements.

  • New Bing Maps

    - by MikeParks
    Normally I don't stray too far from Programming and TFS on my blog posts but I'm just really impressed with how much Silverlight has improved Bing maps. I use to be big on MapQuest, then hopped over to Google, but now the new Bing Maps have everything I need. The two coolest features are right on the main page. All you have to do is go to http://www.bing.com/maps/explore/, enter your city and hit enter in the search box, then look in the lower left corner under the EXPLORE section. Check out the "What's nearby" and "Restaurants" links. The best part is, if you're interested in doing any Silverlight programming, they have a Bing Maps Silverlight Control Interactive SDK. I was thinking about coding something....but they've pretty much got it down :) Pretty impressive stuff.
