• DockbarX Applet not loading

  - by Nik

  I used to have dockbarX applet installed on my gnome panel. However one day when I login in I got a error message which can be seen in the screenshot below. So I removed it, and then tried adding it again to the gnome panel but I still get the error message. I am running the latest version of dockbarX 0.43 with the helpers enabled and media buttons etc. I did not update it recently and have been using this version for a couple of weeks now and got this problem only now. How can I solve this problem?

• Google Analytics Funnel Step Regular Expression Not Working

  - by scoarescoare

  The first step in a funnel is going to have a dynamic ending fragment. Examples: http://mysite.com/invite/tickle-party http://mysite.com/invite/pajama-party http://mysite.com/invite/puppy-party To allow for such dynamism, I provided this url for step one: \invite(.*) My goals work but the funnel visualization report shows 0 for everything. I know this problem is due to the regex in the funnel step because I copied this entire goal except I replaced \invite(.*) with /invite/puppy-party When I hardcoded /invite/puppy-party the funnel worked as expected. Why is my funnel report not working with my original funnel step url parameter?

• suspend not working

  - by Eric

  I am running 13.10 on an ASUS 101-SE netbook. Under "power settings" I have selected suspend when inactive for 10 minutes and suspend when lid is closed. I get a warning when inactive that the computer will suspend due to inactivity, but it does not suspend either from that condition or when closing the lid. I seem to be getting multiple suspend messages as I need to click "cancel" or "OK" many times to get the error window to close when it has been inactive for some time. Anyone have any tips? Thank you.

• Google not recognizing microdata? [duplicate]

  - by user1795832

  This question already has an answer here: How long for data highlighter mark up to appear in structured data tool? 2 answers I put in microdata to one page of a site I help manage using schema.org. Using the Google webmaster tool test, the page checks out and displays what it sees as the microdata properly. But when I go to the Structured Data page in webmaster tools, it keeps saying the site does not have any. I put it in 2 weeks ago. Us it just something that take a while for it to recognize? Or does microdata have to be on every page for it to be recognized or something?

• Memory management in Qt?

  - by Martin

  I'm quite new to Qt and am wondering on some basic stuff with memory management and the life of objects. When do I need to delete / destroy my objects? Is any of this handled automatically? In the example below, which of the objects I create do I need to delete? What happens to the instance variable myOtherClass when myClass is destroyed? What happens if I don't delete / destroy my objects at all, will that be a problem to memory? in MyClass.h: class MyClass { public: MyClass(); ~MyClass(); MyOtherClass *myOtherClass; }; in MyClass.cpp: MyClass::MyClass() { myOtherClass = new MyOtherClass(); MyOtherClass myOtherClass2; QString myString = "Hello"; } As you can see this is quite newbie-easy stuff but where can I learn about this in an easy way? Thanks really much

• GameplayScreen does not contain a definition for GraphicsDevice

  - by Dave Voyles

  Long story short: I'm trying to intergrate my game with Microsoft's Game State Management. In doing so I've run into some errors, and the latest one is in the title. I'm not able to display my HUD for the reasons listed above. Previously, I had much of my code in my Game.cs class, but the GSM has a bit of it in Game1, and most of what you have drawn for the main screen in your GameplayScreen class, and that is what is causing confusion on my part. I've created an instance of the GameplayScreen class to be used in the HUD class (as you can see below). Before integrating with the GSM however, I created an instance of my Game class, and all worked fine. It seems that I need to define my graphics device somewhere, but I am not sure of where exactly. I've left some code below to help you understand. public class GameStateManagementGame : Microsoft.Xna.Framework.Game { #region Fields GraphicsDeviceManager graphics; ScreenManager screenManager; // Creates a new intance, which is used in the HUD class public static Game Instance; // By preloading any assets used by UI rendering, we avoid framerate glitches // when they suddenly need to be loaded in the middle of a menu transition. static readonly string[] preloadAssets = { "gradient", }; #endregion #region Initialization /// <summary> /// The main game constructor. /// </summary> public GameStateManagementGame() { Content.RootDirectory = "Content"; graphics = new GraphicsDeviceManager(this); graphics.PreferredBackBufferWidth = 1280; graphics.PreferredBackBufferHeight = 720; graphics.IsFullScreen = false; graphics.ApplyChanges(); // Create the screen manager component. screenManager = new ScreenManager(this); Components.Add(screenManager); // Activate the first screens. screenManager.AddScreen(new BackgroundScreen(), null); //screenManager.AddScreen(new MainMenuScreen(), null); screenManager.AddScreen(new PressStartScreen(), null); } namespace Pong { public class HUD { public void Update(GameTime gameTime) { // Used in the Draw method titleSafeRectangle = new Rectangle (GameplayScreen.Instance.GraphicsDevice.Viewport.TitleSafeArea.X, GameplayScreen.Instance.GraphicsDevice.Viewport.TitleSafeArea.Y, GameplayScreen.Instance.GraphicsDevice.Viewport.TitleSafeArea.Width, GameplayScreen.Instance.GraphicsDevice.Viewport.TitleSafeArea.Height); } } } class GameplayScreen : GameScreen { #region Fields ContentManager content; public static GameStates gamestate; private GraphicsDeviceManager graphics; public int screenWidth; public int screenHeight; private Texture2D backgroundTexture; private SpriteBatch spriteBatch; private Menu menu; private SpriteFont arial; private HUD hud; Animation player; // Creates a new intance, which is used in the HUD class public static GameplayScreen Instance; public GameplayScreen() { TransitionOnTime = TimeSpan.FromSeconds(1.5); TransitionOffTime = TimeSpan.FromSeconds(0.5); } protected void Initialize() { lastScored = false; menu = new Menu(); resetTimer = 0; resetTimerInUse = true; ball = new Ball(content, new Vector2(screenWidth, screenHeight)); SetUpMulti(); input = new Input(); hud = new HUD(); // Places the powerup animation inside of the surrounding box // Needs to be cleaned up, instead of using hard pixel values player = new Animation(content.Load<Texture2D>(@"gfx/powerupSpriteSheet"), new Vector2(103, 44), 64, 64, 4, 5); // Used by for the Powerups random = new Random(); vec = new Vector2(100, 50); vec2 = new Vector2(100, 100); promptVec = new Vector2(50, 25); timer = 10000.0f; // Starting value for the cooldown for the powerup timer timerVector = new Vector2(10, 10); //JEP - one time creation of powerup objects playerOnePowerup = new Powerup(); playerOnePowerup.Activated += PowerupActivated; playerOnePowerup.Deactivated += PowerupDeactivated; playerTwoPowerup = new Powerup(); playerTwoPowerup.Activated += PowerupActivated; playerTwoPowerup.Deactivated += PowerupDeactivated; //JEP - moved from events since these only need set once activatedVec = new Vector2(100, 125); deactivatedVec = new Vector2(100, 150); powerupReady = false; }

• Sharepoint Expiration Policy not working

  - by spano

  I have a Sharepoint 2010 list with a custom content type with an associated retention policy. The policy consists of a custom formula and then the Send to Recycle Bin action. However, I realized that the items were not being deleted. I verified the list settings and the retention policy was configured: I run the Expiration Policy job several times but no items were deleted and no errors found in the logs. I also added logging to the custom formula but no logging was found neither. Finally, I found...(read more)

• combo microphone does not work on Natty.

  - by Senthil Kumaran

  I have a Internal Audio Hardware card and my Laptop (Lenevo IdeaPad) presents a single slot as a combo Microphone and headphone jack. On Windows, I attach my ipod headphone to jack and speak directly to my computer. I assume there is a microphone which is listening to my voice and I can communicate two-way. On Ubuntu, the microphone always seem to be listening to random noise. So any input by speaking to the computer is not possible. What could be the reason and how do I troubleshoot this?

• To implement registration page with Vaadin or not?

  - by JVerstry

  This is a tactical implementation question about usage of Vaadin or in some part of my application. Vaadin is a great framework to login users and implement sophisticated web applications with many pages. However, I think it is not very well suited to desgin pages to register new users for my application. Am I right? Am I am wrong? It seems to me that a simple HTML/CSS/Javascript login + email registration + confirmation email with confirmation link cannot be implemented easily with Vaadin. It seems like Vaadin would be overkill. Do you agree? Or am I missing something? I am looking for feedback from experienced Vaadin users.

• 12.10 does not boot sometimes from the hard drive, but it does consistently from the CD

  - by Robert

  I have recently switched from Windows 7 to Ubuntu 12.10. I have installed Ubuntu 12.10 and I cleared everything from my computer, but it randomly stops at different screens. Only a purple screen comes up. I can choose Ubuntu from a list and a blinking white dot appears in the top left corner. The previous things happen and the Ubuntu login screen appears an I can log in. It is random. and I have not changed anything. I can always insert the bootable CD and it will work every time.

• Looking for Suggestion on Multi-Consumer Service Development

  - by DaveDev

  How would I model a system that needs to be able to provide content in a format that would be consumable by iphone, Android or web browser (or whatever). All a new consumer would have to do is build a UI with rules on how to handle the data. I'm thinking something RESTful returning JSON or something. I'm really looking for suggestions on the kinds of things I'd need to learn in order to be able to implement a system on this scale. As an ASP.NET MVC developer, would that be the best framework/archetectrue to go with? Thanks

• Where should Nhibernate IPostInsertEventListener go in the 3 tier architecture

  - by Quintin Par

  I have a IPostInsertEventListener implementation like public class NHibernateEventListener : IPostInsertEventListener, IPostUpdateEventListener which catches some entity inserts and does an additional insert to another table for ETL. Essentially it requires references to the Nhibernate, Domain entity and Repository<> Now where do I go about adding this class? If I add it to ApplicationServices I’ll end up referencing Nhibernate at that layer. If I add this to the Data layer, I’ll have to reference Domain (circular). How do I go implementing this class with S#arp principles? Any thoughts?

• How do I improve this design for dealing with intersecting date ranges and resolving date range conf

  - by derdo

  I am working on some code that deals with date ranges. I have pricing activities that have a starting-date and an end-date to set a certain price for that range. There are multiple pricing activities with intersecting date ranges. What I ultimately need is the ability to query valid prices for a date range. I pass in (jan1,jan31) and I get back a list that says jan1--jan10 $4 , jan11--jan19 $3 jan20--jan31 $4. There are priorities between pricing activities. Some type of pricing activities have high priority, so they override other pricing activities and for certain type of pricing activities lowest price wins etc. I currently have a class that holds these pricing activities and keeps a resolved pricing calendar. As I add new pricing activities I update the resolved calendar. As I write more tests/code, it started to get very complicated with all the different cases (pricing activities intersecting in different ways). I am ending up with very complicated code where I am resolving a newly added pricing activity. See AddPricingActivity() method below. Can anybody think of a simpler way to deal with this? Could there be similar code somewhere out there? Public class PricingActivity() { DateTime startDate; DateTime endDate; Double price; Public bool StartsBeforeEndsAfter (PricingActivity pAct) { // pAct covers this pricing activity } Public bool StartsMiddleEndsAfter (PricingActivity pAct){ // early part of pAct Itersects with later part of this pricing activity } //more similar methods to cover all the combinations of intersecting } Public Class PricingActivityList() { List<PricingActivity> activities; SortedDictionary<Date, PricingActivity> resolvedPricingCalendar; Public void AddPricingActivity(PricingActivity pAct) { //update the resolvedCalendar //go over each activity and find intersecting ones //update the resolved calendar correctly //depending on the type of the intersection //this part is getting out of hand….. } }

• Python: Recursively access dict via attributes as well as index access?

  - by Luke Stanley

  I'd like to be able to do something like this: from dotDict import dotdictify life = {'bigBang': {'stars': {'planets': [] } } } dotdictify(life) #this would be the regular way: life['bigBang']['stars']['planets'] = {'earth': {'singleCellLife': {} }} #But how can we make this work? life.bigBang.stars.planets.earth = {'singleCellLife': {} } #Also creating new child objects if none exist, using the following syntax life.bigBang.stars.planets.earth.multiCellLife = {'reptiles':{},'mammals':{}} My motivations are to improve the succinctness of the code, and if possible use similar syntax to Javascript for accessing JSON objects for efficient cross platform development.(I also use Py2JS and similar.)

• Is there a name for a language feature that allows assignment/creation?

  - by Alex Mcp

  This is a bit hard for me to articulate, but in PHP you can say something like: $myArray['someindex'] = "my string"; and if there is no index named that, it will create/assign the value, and if there IS an index, it will overwrite the existing value. Compare this to Javascript where today I had to do checks like so: if (!myObject[key]) myObject[key] = "value"; I know this may be a bit of a picky point, but is there a name for the ability of PHP (and many other languages) to do these checks on their own as opposed to the more verbose (read: PITA) method of Javascript?

• What are pointers to class members used for?

  - by srikfreak

  I have read about pointers to class members, but I have never seen them being used in any practical applications. Can someone explain what are the use cases of such pointers? Is it really necessary to have such pointers? Eg. class abc { public: int a; abc(int val) { a = val; } }; int main { int abc::*data; abc obj(5); data = &abc::a; cout << "Value of a is " << obj.*data << endl; return 0; } In the above eg. why is the value of 'a' accessed in this manner? What is the advantage of using pointers to class members?

• SOA design principles with regards to database relationships

  - by Eitan

  If I were to extricate my current membership provider from my solution, i.e. as a dll and expose it as a web service with it's own db, how would I model the relationships with regards to SOA design. For example I have a table: USER id, name, lastname, username, password, role. and table PRODUCT id, name, price, createdate, userid the foreign key being userid to table user. How would I model the relationship and/or query the db. If I wanted to get all products that were uploaded today for example, before I would query: SELECT u.name, u.lastname, u.username, p.* FROM PRODUCT p INNER JOIN USER u ON p.userid = u.id WHERE createdate = '05/05/2010' Now that I don't have the table within the database how would I perform this query? Thanks.

• Switch from encrypted partition to unencrypted (Error: cryptsetup: evms_activate is not available)

  - by Chris Lercher

  I initially installed Ubuntu 11.04 with an encrypted file system (from the alternate install CD: Guided Partitioning, LVM encrypted). Now I wanted to change this setup to have my root file system on an unencrypted partition. I had the following setup before: /dev/mapper/my-root on / type ext4 (rw,noatime,errors=remount-ro,commit=0,commit=0) /dev/sda1 on /boot type ext2 (rw,noatime) I backed up /, reformatted /dev/sda5 (which had contained the encrypted LVM device) to an ext3 partition, and restored / to that partition. I edited /etc/fstab, removed the line /dev/mapper/my-root / ..., and added the line: /dev/sda5 / ext3 noatime,rw,errors=remount-ro,commit=0 0 1 I edited /etc/crypttab, and commented out the single entry. On reboot, I get the grub screen as usual, but then I get the message cryptsetup:evms_activate is not available, waiting for encrypted source device. I tried reinstalling Grub2 using a LiveCD with the ChRoot method, but that didn't make any difference. Why is Ubuntu still searching for an encrypted device?

• Entity Framework - refresh objects from database

  - by Nebo

  I'm having trouble with refreshing objects in my database. I have an two PC's and two applications. On the first PC, there's an application which communicates with my database and adds some data to Measurements table. On my other PC, there's an application which retrives the latest Measurement under a timer, so it should retrive measurements added by the application on my first PC too. The problem is it doesn't. On my application start, it caches all the data from database and never get new data added. I use Refresh() method which works well when I change any of the cached data, but it doesn't refresh newly added data. Here is my method which should update the data: public static Entities myEntities = new Entities(); public static Measurement GetLastMeasurement(int conditionId) { myEntities.Refresh(RefreshMode.StoreWins, myEntities.Measurements); return (from measurement in myEntities.Measurements where measurement.ConditionId == conditionId select measurement).OrderByDescending(cd => cd.Timestamp).First(); } P.S. Applications have different connection strings in app.config (different accounts for the same DB).

• What happens to an ActiveX control (COleControl) after the call to OnDestroy() ?

  - by richj

  I have an ActiveX control written in C++ that runs in Internet Explorer 8. Most of the time (approx 90%) when the tab or browser containing the control is closed, there is an access violation like this: The thread 'Win32 Thread' (0x1bf0) has exited with code 0 (0x0). Unhandled exception at 0x77b3b9fd in iexplore.exe: 0xC0000005: Access violation reading location 0x65007408. The access violation occurs after the call to OnDestroy() but before the call to the control's destructor. The debug output says: No symbols are loaded for any call stack frame. The source code cannot be displayed. None of my code is present in the stacktrace, although perhaps the heap was corrupted at some earlier point during execution. What lifecycle events does an ActiveX control receive between the call to OnDestroy() and the control's destructor?

• Conditional relation

  - by Lowgain

  I've got a model like this: Stem -id -etc And then I have Stemrelation -stem_id -related_stem_id -active I can get the related stems with the following relations class Stem < ActiveRecord::Base has_many :stemrelations has_many :related_stems, :through => :stemrelations end class Stemrelation < ActiveRecord::Base belongs_to :stem belongs_to :related_stem, :class_name => "Stem", :foreign_key => "related_stem_id" end But now I'd only like to get the active relations. I tried adding this to the Stem model: has_many :active_related, :through => :stemrelations, :source => :related_stem, :conditions => {:active => true} but this gives me an error becasue it tries to check the active flag on the stem model instead of the stemrelation. What do I change here? Thanks!

• USB Logitech Rumble Pad 2 gamepad AND Thustmaster Universal Challenge Wheel not working in wine

  - by Rick Gionfriddo

  The controller is detected by the OS, and shows up in lsusb, and I can configure it with jstest-gtk, but Live For Speed in Wine doesn't recognize it as connected. Using Lubuntu 12.04, wine version 1.5.5. P.S. - It worked on a previous install of regular Ubuntu 12.04, using the same Wine version. Have tried installing/overriding/un-overriding various DLL's through winetricks to no avail, including xact and dinput8. Since it worked in a previous install of the same version, I figured it was a configuration error, and that I should ask here as opposed to put in a bug report on winehq. EDIT: I just used both controllers in TORCS... why do they work in native games, but not in wine?
