• DRIconf in Ubuntu 64x plus ATI GPU or something more?

  - by Balask

  I've been trying to get Call of Duty 2 to work in Wine in Ubuntu. It gives me a black screen. So I tried the fix suggested by the wine apphq and downloaded DRIconf. Funny thing is that it can't find my direct rendering device. "Could not detect any configurable direct-rendering capable devices. DRIconf will be started in expert mode" When I enter into it in Expert Mode is just errors out anyway. fglrxinfo gives me: display: :0 screen: 0 OpenGL vendor string: Advanced Micro Devices, Inc. OpenGL renderer string: ATI Mobility Radeon HD 4200 Series OpenGL version string: 3.3.11627 Compatibility Profile Context That shows me my driver is installed correctl,y right? World of Goo which is Linux native and requires direct rendering works like a charm. So I'm wondering, is there some other workaround? Is there a bigger issue? Does me running 64-bit affect it at all?

• How do I remove Skype 4.3 from Ubuntu 14.04 LTS (32-bit)

  - by Lucas W

  I installed Skype on my nephew's new Ubuntu 14.04 LTS machine, and now we've decided to remove it. But I'm not able to locate it in my Installed programs section of Ubuntu Software Center. I'm able to call it up by opening the debian package, Software Center opens it up, but where I would normally see the "Remove" button, I have a "Reinstall" button. For the life of me, I can't figure out how to uninstall Skype. Any suggestions? In case you're wondering I used the version of Skype designed for 12.xx, as there was no option available for Ubuntu 14.xx.

• Stores Still Matter In The World Of E-Commerce

  - by Michael Hylton

  You may think that more and more consumers are moving their purchasing to the Web or mobile device.  However, according The NPD Group, Inc., a leading market research company, 15-20 percent of consumers in 2011 checked out products in stores before buying online, or called “showrooming”, for product categories like stand mixers, electric knives, sewing machines, and some floor cleaners. Other categories like power tools, hairsetters, and robotic vacuums are now beginning to show signs of the “showrooming” trend as well. It is doubly important to present a consistent, personalized, and relevant shopping experience for your customers, no matter whether they interact with you in-person in your store, with your sales agents or call center agents, over the Web, or using a mobile device.  Your goal is to make that experience across touchpoints as seamless as possible.

• Elastic Collision Formula in Java

  - by Shijima

  I'm trying to write a Java formula based on this tutorial: 2-D elastic collisions without Trigonometry. I am in the section "Elastic Collisions in 2 Dimensions". In step 1, it mentions "Next, find the unit vector of n, which we will call un. This is done by dividing by the magnitude of n". My below code represents the normal vector of 2 objects (I'm using a simple array to represent the normal vector), but I am not really sure what the tutorial means by dividing the magnitude of n to get the un. int[] normal = new int[2]; normal[0] = ball2.x - ball1.x; normal[1] = ball2.y - ball1.y; Can anyone please explain what un is, and how I can calculate it with my array in Java?

• Avoid Code Repetition in Condition Statements

  - by Ethosik

  I have been programming for over 15 years now. I consider myself a very good programmer, but I understand (like all of us) there are things that I need to work on. One of these things is code repetition when dealing with conditions. I will give a generic sample: if(condition1) { //perform some logic if(condition2) { //perform some logic if(condition3) { //Perform logic } else { //MethodA(param) } } else { //MethodA(param) } } else { //MethodA() } Now, I cannot make it easy by doing the following: if(condition1 && condition2) { } else { } I cannot do this since I need to perform some logic if condition1 is true and before I test condition2. Is there a way to structure if...else blocks to where if you need to call a method in each else blocks, you are not repeating yourself?

• Touch Event Not Work With PinchZoom

  - by Siddharth

  I was implemented pinch zoom functionality for my tower of defense game. I manage different entity to display all the towers. From that entity game player select the tower and drag to the actual position where he want to plot the tower. I set the entity in HUD also, so user scroll and zoom the region, the tower become visible all the time. Basically I have created the different entity to show and hide towers only so I can manage it easily. My problem is when I have not perform the scroll and zoom the tower touch and the dragging easily done but when I zoom and scroll the scene at that time the tower touch event does not call so the player can not able to drag and drop it to actual position. So anybody please help me to come out of it.

• OpenGL Beginner question

  - by nobby

  I'm new to OpenGL programming, but I can't find a good book to read or a tutorial, I've tried reading through the superbible or whatever its name is but it's kind of complicated to me. The tutorial at http://duriansoftware.com/joe/An-intro-to-modern-OpenGL.-Chapter-2.3:-Rendering.html is pretty ok but it doesn't cover what I need mostly, which is opengl math etc (such as projection matrix, view matrix, and so on). I'm fairly OK at C(++) (3+ years experience, I don't know if you would call that "good") What i basically want to do with OpenGL is, make a simple game (prefer 2D as a start and not 3D). Please suggest a good EBook to read and learn from.

• Open a popup window from Silverlight

  - by Emanuele Bartolesi

  Silverlight has a method called HtmlPage.PopupWindow() that opens new web browser window with a specific page. You can find this method in the namespace System.Windows.Browser. If you haven’t in your project, add a reference to System.Windows.Browser. The method HtmlPage.PopupWindow() has three parameters: Uri – location to browse String – the target window HtmlPopupWindowOptions – a class with the window options (full list of properties http://msdn.microsoft.com/en-us/library/system.windows.browser.htmlpopupwindowoptions(v=vs.95).aspx) For a security reason of Silverlight the call to HtmlPage.PopupWindow() is allowed through any user input like a button, hyperlink, etc. The code is very simple: var options = new HtmlPopupWindowOptions {Left = 0, Top = 0, Width = 800, Height = 600}; if (HtmlPage.IsPopupWindowAllowed) HtmlPage.PopupWindow(new Uri("http://geekswithblogs.net/"), "new", options); The property IsPopupWindowAllowed is used to check whether the window is enabled to open popup.

• Moving a LAMP set up from 32 bit to 64 bit

  - by user10157

  Hello everyone... I have setup an Ubuntu server 10.10 32bit on an old Dell D610 Laptop for testing. I have the latest PHP, MySQL and Apache with Wordpress installed. After the testing is over and once I finish adding material to my wordpress I will build a Ubuntu 10.10 64bit VM on Hyper-V. What I am wondering is , if it's best practice to build everything from scratch (which will take me more time and would like to avoid) or transfer the database and all other settings? If I choose to transfer how and what I need to do? Here's where I'd like some help as I am still an intermediate admin (If I can call it that!) I am looking forward for your help. Thanks!

• Rendering trillions of "atoms" instead of polygons?

  - by Baring

  I just saw a video about what the publishers call the "next major step after the invention of 3D". According to the person speaking in it, they use a huge amount of atoms grouped into clouds instead of polygons, to reach a level of unlimited detail. They tried their best to make the video understandable for persons with no knowledge of any rendering techniques, and therefore or for other purposes left out all details of how their engine works. The level of detail in their video does look quite impressive to me. How is it possible to render scenes using custom atoms instead of polygons on current hardware? (Speed, memory-wise) If this is real, why has nobody else even thought about it so far? I'm, as an OpenGL developer, really baffled by this and would really like to hear what experts have to say. Therefore I also don't want this to look like a cheap advert and will include the link to the video only if requested, in the comments section.

• Print all values in a value object

  - by SKDev

  I have to debug an issue which requires me to print all the values of a Value Object that is returned by a web service call. The Value object is a complex object in the sense, it has another object as its member which in turn has another object. Printing all the values by using get methods is cumbersome. So was wondering if there is a way to break down the value object by any way to get to a primitive level like String or int or Date and print them all using one API? I had a look at the below question but my prob is that i don't have access to the source code of the value object. The sources are in obfuscated jar. http://stackoverflow.com/questions/2413001/how-to-print-values-of-an-object-in-java

• How do I recover a site after WordPress' Automatic Update has failed?

  - by Metacom

  I manage several WordPress websites, and successfully recently used the Automatic Upgrade feature to bring them up to 3.1. However, on one of the sites, I received a 503 (I believe it was 503). After that I was presented with "The service is unavailable." whenever I tried to access any page, including the index page, wp-admin, etc. I had similar problems before when a WordPress site got stuck in maintenance mode, and all I needed to do was login via FTP and rename or delete the .maintenance file. I tried that in this case, but that didn't do the trick. I am now presented with "Fatal error: Call to undefined function require_wp_db() in **\wp-settings.php on line 71" I can't figure out how to fix this problem, and I was wondering if anyone else had any ideas. Any suggestions are appreciated! Thank you for reading.

• Programming error in 'aptdaemon' [closed]

  Using Ubuntu 11.10 While performing updates through the update manager I get the following message: An unhandlable error occured There seems to be a programming error in aptdaemon, the software that allows you to install/remove software and to perform other package management related tasks.

• If I have true i/o false or vice versa, is it an OBOE?

  - by Protector one

  I often make the mistake of inverting my truth values in my code (e.g. in my if clauses). It gives me the same feeling as when making an OBOE (Off By One Error), even though it's technically not. Would you call it an OBOE, or better yet, is there a specific term for "off by truth value"-errors? My reasoning is that all possible values of a boolean are true and false. In other words, the possible values are contained in the array: [true, false]. If you access this array by index, you'll always be off by one… when selecting the wrong one. This becomes especially obvious when you calculate your index as: index = someInt % 2. Now I understand that this usually not the case, but in my mind, it always feels like this. Almost got it, just off by one…

• Generating CMakeLists.txt

  - by vanna

  I got a bunch of C++ sources files and headers. They may use external libraries such as Boost e.g. I am interested in the process of building binaries for Windows and *nix. Makefiles (*nix) and .vcproj (Windows) call compilers with some specifications such as the order of compilation, compilation options and stuff. CMakeLists.txt can be used by CMake to build either makefiles or .vcproj and use very helpful commands such as recursive search of files, automatic linkage with known libraries, installers, variables that can be used in source files... Is there any existing tool that would generate a CMakeLists.txt from specified options ? Options could be like : scan this folder and make a library out of it, then scan this other folder and make an executable and automatically link both with Boost as well along with a user friendly installer with generated INSTALL.txt and README.txt. Something very powerful like that.

• What makes a language (or feature) "hackerish"?

  - by iCanLearn

  I was reading the comments and answers to this question, and among them I found this: "And Java never was cool, simply because it threw the hacking part out of programming" and this: "And javascript is very hackerish language so after developing your frontend you feel very constraint when you return to java." What's the "hacking part" in programming, and what makes a language "hackerish"? What are some good examples of languages and features in languages that you would call "hackerish"? (Someone might say that I shouldn't be confused by the word "hackerish", that's it's not really a "proper" English word or something like that, but that's besides the point)

• How to minimize the data loss when laying off a programmer?

  - by thursdaysgeek

  I was just laid off and it was the standard process that is used in the US: call the person to talk to personnel, and remove access to the network while that is going on, then have someone help pack, always have someone with the person until they are escorted from the property. That is supposed to keep an unhappy developer from deleting or damaging software or data: to mimimize data loss. However, it still results in a lot of data loss, as all of the work the programmer was working on is dropped: software not checked in is possibly lost, documents not finished are lost, releases in process are slowed down or stopped, and a huge amount of knowledge could be lost. It seems the potential data loss is more than offset by the actual data loss. How can all losses, both potential and actual, be mimimized?

• Parallel Threading in Multi-Language Software?

  - by Smarty Twiti

  I'm developing a software that contain many modules/Daemon running in parallel manner, what i'm looking for is how to implement that, i cannot use Thread because some of those modules/Daemon are perhaps implemented in other languages (C,java,C#...). For example I'm using C for Hooking Messages exchanged between Windows kernel and top level applications, Java/C# to use some free library to simply parse XML(for example) or to accept and execute commands over the network..this can be done by C Language but just to improve productivity... Finally for GUI I'm using Ultimate++ (c++) that is like the main process that call and monitor(activate/deactivate/get state) of all other modules/Daemon through an interface. I admit that the development of each module/Daemon in a separate language greatly facilitates maintenance, but especially I am obliged to do that.. What is the best practice way to do that ? All helps will be appreciated.

• Why do packages fail to install from command line

  - by calebB

  Every once in a while I can't install packages in Ubuntu 11.04. I'll try to run the software center and it and it will pop up then disappear. If I call it from the command line it says it seg-faults. And then trying to install anything from the command line I get this: sudo apt-get install pdftk Reading package lists... Done And thats all I get for anything I try. Usually restarting fixes the problem but its very annoying.

• After upgrade my webcam mic records fast, high pitched, and squeaky only in Skype (maybe Sound Recorder problem too)

  - by Dennis

  After an upgrade to 11.10 which probably also updated Skype to 2.2.35 (not sure because I never checked the version before) the sound that comes back from an echo test is very high pitched and squeaky. I'm not sure if when in a call if the other person can't hear or just doesn't know what they are hearing. I am using a USB Logitech C250 Audacity records fine, gmail video chat works fine, but if I start sound recorder I get a "Could not negotiate format", followed by "Could not get/set settings from/on resource". I don't know if this is a Skype problem or a wider Pulse problem. My only real needs are the gmail and Audacity, though I have a couple of contacts that I can only Skype with.
