• Examples of Android Joystick Controls? [on hold]

  - by KRB

  I can't seem to find any well executed code examples for Android joystick controls. Whatever it may be, algorithms, pseudo code, actual code examples, strategies, or anything to assist with the design and implementation of Android joystick controls; I can't seem to find anything decent on the net. What are some well executed examples? More specifically, Pseudo Code Current Examples Idea/Design Functionality Description Controller Hints Related Directly to Android Architecture What kind of classes will I have making this? Will there be only one? How would this be implemented to the game architecture? All things I am thinking about. Cheers! UPDATE I've found this on the subject Joystick Example1, though I am still looking for different examples/resources. Answered my own question with a link to the code of the above video. It's a fantastic start to Android Joystick Controls.

• what else except web development is a good choice for freelancing? [closed]

  - by Sali

  I'm looking for a technology that when I learn I can build useful things that brings money by selling what I have built. I tried web development but Ifound that there are many things that I have to learn: html, css, javascript,ajax,jquery ,etc. I need to focus on one thing and learning it from scratch and continue learning if there is any update in that technology rather than learning new things in css and javascript and the server side language. I want to focus! However, I'm not sure what is going on in the future of technology and I need to learn something for freelancing. could you tell what is the thing thatis popular and will bring me money as good as web development?

• Include in service layer all the application's functions or only the reusable ones?

  - by BornToCode

  Background: I need to build a main application with some operations (CRUD and more) (-in winforms), I need to make another application which will re-use some of the functions of the main application (-in webforms). I understood that using service layer is the best approach here. If I understood correctly the service should be calling the function on the BL layer (correct me if I'm wrong) The dilemma: In my main winform UI - should I call the functions from the BL, or from the service? (please explain why) Should I create a service for every single function on the BL even if I need some of the functions only in one UI? for example - should I create services for all the CRUD operations, even though I need to re-use only update operation in the webform? YOUR HELP IS MUCH APPRECIATED

• Ubuntu 12.04 wallpaper problem when using two monitors

  - by jiomsa

  I am using two monitors, the main resolution is 1920x1080 and the secondary is 1440x900. Everything seems to work fine (with default drivers, fglrx crashes bad), besides windows opening in the wrong monitor (even when the main is set correctly), but now what I am trying to fix is the wallpaper problem, here's an image to explain it easier: http://i.imgur.com/msLRR.jpg It also happens with gradients. The secondary monitor is physically aligned like in the image, lower than the other, the wallpaper on the main screen seems to keep the size of the lower resolution, and then it start at the correct resolution the last part at right. Any way to fix this? I am using Ubuntu 12.04 with Gnome-Shell 3.4.1, the vga is a Radeon HD 6950 UPDATE I went to gnome-tweak-tool and disabled "Have file manager handle the desktop", now it looks ok on both monitors, but I can't have icons on my desktop, so I am still interested in solving it. UPDATE2 Disabling "Have file manager handle the desktop", in gnome-tweak-tool and then re-enabling it seems to work, but has to be done every time you turn on the PC.

• How to prepare for an online job interview (maybe through Skype)?

  - by phunehehe

  I'm applying for a company far away and if I get an interview it will probably be done remotely. I have been searching for advices regarding this but all tips seem to be directed at face-to-face meetings (things like "shake hands firmly"). What are the differences? How can I make the best out of those differences? Update: This is a software developer position, so there's also something about technical questions (such as, I can Google anything that they ask ;) This question also applies to any freelancers who are dealing with customers, or recruiters who are interviewing remotely. I hope that makes it relevant to this site. It may also help if you keep answers programers-related.

• What options do I have for a Wedding Car website? [on hold]

  - by David

  I currently run a Wedding Car website that is ranking in the top 5 for my local area, its not doing so well outside of that. I have listed the company in Google Business so it shows in the SERP and I have a Facebook and Twitter account linked, that I update regularly. I know keeping content fresh is important but nothing much changes so I am unsure what options I have? Should I create a blog and talk about the cars, weddings etc? I am totally unsure where to go with this website, the site currently has a few images and a small amount of text. Things I am considering, but would like advice on: A Mobile version of the website A Blog on the website A gallery page with pictures and descriptions Asking local companies to link to my website Essentially I have a small business website but not much content, because really there isnt! I am looking for long term organic ways to get a good seo rank.

• How to keep specific old kernel on my next kernel upgrade?

  - by tvrtko

  I just updated my Ubuntu 14.04 and got a new kernel. This new kernel is not working properly for me so I booted the previous version. Let's call this good old working version "3.13.0-24.47". Now, I want to keep this "3.13.0-24.47" version until I decide to delete it manually. I want to be able to upgrade my kernel each time there is a new version in hope of getting the one which works again. Until then, I want to use the "3.13.0-24.47". I'm afraid that next update will delete my "3.13.0-24.47" version because there are only two kernel versions available at a given time on my system (/boot).

• How do I download a corrupted package again?

  - by user64720

  Ubuntu 12.04 can't install Firefox 13 update, because the package is corrupted. While attempting to install, returns this error (I translated it from my language to English). /var/cache/apt/archives/firefox_13.0+build1-0ubuntu0.12.04.1_i386.deb W: Waited for dpkg --assert-multi-arch but was not there - dpkgGo (10: There are no "child" processes). I can tell that the package at /var/cache/apt/archives/firefox_13.0+build1-0ubuntu0.12.04.1_i386.deb is corrupted, but even as admin, I can't delete it in order to be downloaded again. How should I proceed? EDIT: There was a single package causing this conflict, please report here to understand all the situation: Why can't I install from software center?

• Where can I find good (well organized) examples of game code?

  - by smasher

  Where can I find good (well organized) examples of game code? I'm hoping that I can pick up some organizational tips. Most examples in books are too short and leave out lots of detail for the sake of brevity. I'm particularly interested on how to group your variables and methods so that another programmer would know where to look in the code. For example initializers at the top, then methods that take input, then methods that update views. I don't care about a particular language, as long as its OOP. I looked at the Quake 2 and 3 sources, but they're straight C and not much help for getting tips on organizing your objects. So, have you seen some good source? Any pointers to code that makes you say "wow, that's well organized" would be great.

• Listening For and Raising Events in the BLL

  - by OneSource

  I'm working on a WinForms .Net Recording App and I have a RecordingMgr in my BLL to listen for new events captured by another class. I want to display the events in my UI and I'm stuck as to what's the best way to do this. I can think of a few scenarios to handle this but all of them seem sub-optimal: Listen for and handle Recorded Events in both the UI and in the RecordingMgr After receiving the event in the RecordingMgr, raise it again so that the UI can pick it up Create a variable in RecordingMgr (e.g., a BindingList) that the UI can bind to and update it when an Event is received Ditch the RecordingMgr and just put the event recording logic in the UI What's the best approach? Something above or something else?

• How to install programs downloaded from the internet?

  - by Rosamunda Rosamunda

  I've downloadad the latest XAMPP file, to install it into Ubuntu 13.04. After downloading the file, I just can run it. I've double click it (and I've tried right click and clicking "open", whith the same result). All the answer I get is this message: Could not display “xampp-linux-1.8.3-1-installer.run”. There is no application installed for “executable” files. Do you want to search for an application to open this file? I've tried searching for an application, with no result... Also, I haven't found any questions related to this issue with the 13.04 Unity version... I've tried this solution, with no result. Please note that this isn't a Xampp question, the same happened to me when I tried to install Skype. UPDATE: I've tried this solution: cd ~/Downloads chmod +x myfile.run sudo sh myfile.run And I've got this error: Syntax error: "(" unexpected What should I do? Thanks!

• Installing g++ on 8.04

  - by mathematician1975

  I am running Ubuntu 8.04 (currently I do not have the option to upgrade due to hardware problems). I need to get g++ onto my installation but as this is no longer supported I am unable to use the traditional apt-get approach. What are my options? Are ubuntu packages configured specifically for each version? For example could I manually download a later version of gcc and g++ that do not originally ship with 8.04 (say the 10.04 version for example) and build them from scratch? Do the compilers work in this way in the sense that they have a version PER ubuntu version or are they maintained as separate entities?? I do not know enough about ubuntu internals really and always use apt-get to obtain/update any packages I need. If it is possible to do it this way is there a way to be certain that I have everything I need with regards to utility packages needed by g++ for the installation??

• Should I understand SVN before I jump to GIT?

  - by John Isaacks

  I work in a department where no one has ever used source control before, including myself. I am trying to push the concept. I have spent a little while researching SVN. I some basics learned. I can Create/update/checkout/commit with command line and from Tortoise. I am starting to learn how to tag and branch but still confused a lot about conflicts between branches and trunk etc. I am still learning, but I do not have a physical person who can show me anything. Its all from books/tutorials and trial and error. From what I have read online it seems like git is the better thing to know, but its also more complicated. I don't want to overwhelm myself. Should I continue to master svn before moving to git or would I be wiser to just jump to git now? Are there pros and cons to both approaches?

• Trouble installing 12.04 from cd, blank screen with cursor

  - by Master Morality

  I should preface this with saying that this is not my first rodeo. I started playing with Linux in 1999 (Red Hat) and I'm currently typing this on a ThinkPad running 12.04... When I put in the live cd, I boots, and I can get to the option menu to decide whether to install/run etc, but at any point beyond that I get only a single caret. I can type stuff in, but it goes no where. I've tried the usual stuff like running with nomodeset (thinking it was the intel HD400 graphics, but it is integrated graphics...) here is the setup: ASUS p8z77 pro (with the Atheros AR9485 wifi supposedly, but I'm not that far yet) i7 3370k 8gig X 2 G.Skill Crucial M4 (256 gig) LG Super-multi DVD re-writer no video card UPDATE: I though may be it was a bad image on the CD, so I downloaded another iso, and used a USB disk. now it boots to a blank screen. I can see the "press any key to get options" screen, but after that, it just goes to a blank screen.

• Need to run `nvidia-xconfig` before booting

  - by RobinJ

  I formatted my whole hard drive, and installed Elementary OS (Ubuntu 10.10) on it in an attempt to get rid of all the problems. It failed. Every since I installed the nvidia-current drivers I first need to boot into recovery mode, and run sudo nvidia-xconfig before booting the system in the normal way. If I don't do this, it will just stop at a black screen after the boot screen, responding to nothing but CTRL+ALT+DELETE and the power button. When I boot the system after running the nvidia-xconfig command I can just start working as usual. Update I suspect it's got something to do with Plymouth. I shall have to try it again before I can confirm it, but removing the quiet and splash parameters from the kernel line in /boot/grub/grub.cfg seems to help. But still, I like my Plymouth screen. A black screen with text rolling over it (or without the text) doesn't attract me much.

• Battery icon constantly empty when discharging Vaio VGN-FZ210CE

  - by Alex

  I have a Sony Vaio VGN-210CE laptop, and its battery does not report the drain rate properly. In 11.10 and earlier, the battery icon would update with the percentage, not the estimated time. In 12.04 and 12.10, it estimates by time, which is always some very low value because the estimated drain rate is 700W. I currently have 89% in my battery but the icon is red and empty. If there is an application I should install, or a setting I should change, please let me know. Thanks!

• Repelling a rigidbody in the direction an object is rotating

  - by ndg

  Working in Unity, I have a game object which I rotate each frame, like so: void Update() { transform.Rotate(new Vector3(0, 1, 0) * speed * Time.deltaTime); } However, I'm running into problems when it comes to applying a force to rigidbodies that collide with this game objects sphere collider. The effect I'm hoping to achieve is that objects which touch the collider are thrown in roughly the same direction as the object is rotating. To do this, I've tried the following: Vector3 force = ((transform.localRotation * Vector3.forward) * 2000) * Time.deltaTime; collision.gameObject.rigidbody.AddForce(force, ForceMode.Impulse); Unfortunately this doesn't always match the rotation of the object. To debug the issue, I wrote a simple OnDrawGizmos script, which (strangely) appears to draw the line correctly oriented to the rotation. void OnDrawGizmos() { Vector3 pos = transform.position + ((transform.localRotation * Vector3.forward) * 2); Debug.DrawLine(transform.position, pos, Color.red); } You can see the result of the OnDrawGizmos function below: What am I doing wrong?

• Correct process for creating builds reliant on 3rd party packages

  - by Patrick

  I work on a Symfony 2 codebase. We use a number of third-party packages (most are in the Symfony Standard Edition). We use composer for dependencies. We current have all of our third-party code committed in our repository (after changing .gitignore files) to ensure stability. According to Proper Programming Practices™, we are not supposed to have any third-party packages in our repo. We are supposed to pull them down and include them at build time. How are we to do proper QA and debugging when at any given time our dependencies could push an update that breaks functionality?

• frequency out of range - please change display mode

  - by Dave

  I just downloaded the latest version of the Ubuntu live CD, and have installed it on a desktop computer (a Fujitsu Scaleo P). Once installed it seems to work perfectly, although there are some updates recommended in the Update Manager. My problem is that, after having installed these updates and restarted the computer, I get this message on my monitor, and no Ubuntu interface is visible: frequency out of range - please change display mode I do not know how to change this when I can't access an interface. Is there a command that will bypass trying to boot the GUI and let me change the display mode via a CLI? I am brand new to Ubuntu and any help on this would be much appreciated.

• Grub-Customizer made Windows 7 disappear from Gurb2

  - by user199055

  I am running dual-boot Ubuntu 12.04/Windows7. I wanted to change the boot order in Grub2 to have Windows on top of the list. I installed Grub-Customizer on Ubuntu 12.04 using the following terminal commands copied from another post: sudo add-apt-repository ppa:adabbas/1stppa sudo apt-get update sudo apt-get install grub-customizer After installing, I launched Grub-Customizer from Dash Home. Windows 7 does not appear in the list. I closed the program and was prompted to save the current settings. Upon rebooting, Windows did not appear in the Grub2 list. I went back into Grub-Customizer and clicked the "Revert" button but still no Windows 7. Does anyone know how I can fix this?
