• Get Creative soundcard working correctly

  - by schwiz

  I am trying to get sound going on my fresh install of 10.10. I have a creative fatlity branded sound card. My ALSA information. Most things seems to be working out of the box, once I turned off my onboard sound in my BIOS the soundcard kicked in. However, the system sounds aren't working (I love those drums and the road runner sound when you press backspace). Also, with a 7.1 setup my center channel and subwoofer don't work at all. All other channels are working like a champ. So I am trying to accomplish two things, get system sounds working and get center/sub channels working. How should I try to fix this?

• What Extends JComponent?

  - by Geertjan

  Let NetBeans IDE tell you what extends JComponent: Thanks to Damian from Gdansk in Poland who left a comment in this blog yesterday that explains how to achieve the above: "Let's say you would like to find all implementations of TreeModel interface. I found today an answer: r-click on class/interface -> chose Navigate->Inspect Hierarchy->select second filter at the bottom of opened window or press Alt+Shift+F12 and then Alt+B." In the list above, double-click an item to open it in the NetBeans Java editor. Handy tip, dziekuje bardzo, Damian.

• Windows 7 can't boot with Ubuntu on different hard drive

  - by dellphi

  I use a dual boot with two hard disks and two OS is Ubuntu 10.04 and Windows 7. Windows 7 installed on the first disk, first partition. Grub is installed on a second hard disk MBR, and Ubuntu installed on an extended partition on a second hard drive. When I select Windows 7 on the Grub menu, the HDD lamp lights up briefly and then black screen on the monitor, with the status of the keyboard is still functioning. Until now (with the default boot from first HDD), I have to press F12 to get into the Grub to run Linux on a second HDD. output of fdisk -l grub.cfg. I want to retain Grub to remain on the second HDD, and Windows 7 could choose from the menu provided by Grub. But I do not get how, I hope anyone can help.

• How can I factor momentum into my space sim?

  - by Josh Petite

  I am trying my hand at creating a simple 2d physics engine right now, and I'm running into some problems figuring out how to incorporate momentum into movement of a spaceship. If I am moving in a given direction at a certain velocity, I am able to currently update the position of my ship easily (Position += Direction * Velocity). However, if the ship rotates at all, and I recalculate the direction (based on the new angle the ship is facing), and accelerate in that direction, how can I take momentum into account to alter the "line" that the ship travels? Currently the ship changes direction instantaneously and continues at its current velocity in that new direction when I press the thrust button. I want it to be a more gradual turning motion so as to give the impression that the ship itself has some mass. If there is already a nice post on this topic I apologize, but nothing came up in my searches. Let me know if any more information is needed, but I'm hoping someone can easily tell me how I can throw mass * velocity into my game loop update.

• Parse and display MIME multipart email on website

  - by aidan

  I have a raw email, (MIME multipart), and I want to display this on a website (e.g. in an iframe, with tabs for the HTML part and the plain text part, etc.). Are there any CPAN modules or Template::Toolkit plugins that I can use to help me achieve this? At the moment, it's looking like I'll have to parse the message with Email::MIME, then iterate over all the parts, and write a handler for all the different mime types. It's a long shot, but I'm wondering if anyone has done all this already? It's going to be a long and error prone process writing handlers if I attempt it myself. Thanks for any help.

• Change color of text within a RichTextBox in C#

  - by Addie

  I have a RichTextBox that I write a string to every time I click a Form button. The string ends with a newline so each time I add a string, it appends to the bottom of the RichTextBox. Each string begins with the string "Long" or "Short" and ends with Environment.NewLine. I'd like to color each line red if it beings with "Long" and blue if it begins with "Short". How can I do this? If you need further clarification of the question comment below.

• handle user logoff or machine shutdown requests on WindowsME

  - by skylap

  I have to write a C# application that runs on WindowsME. Yes, I mean that Microsoft operating system that has been forgotten a long long time ago. My program needs no user interaction and as WindowsME doesn't support services, it will be a console application. Furthermore it will be used on more modern operating systems, where the user can choose whether to start it as console application or install it as a windows service. Now suppose the software is running on WinME and the user decides to logoff or shutdown the machine without a prior quit of my software. WinME complains about my program still running and asks if it should kill the process. Apart from the bad user experiance, this means that the application is not shut down properly. So I look for a way to be informed if the user logs off or wants to shutdown the machine to be able to perform a proper shutdown of my software first.

• Grub does not autoboot the default option after upgrade to 12.10

  - by Petr Kozelka

  I recently upgraded Ubuntu from 12.04 to 12.10 and since that time, the system does not automatically boot. It always opens the boot menu, and I have to press Enter to make it boot Ubuntu. It seems to be ignoring the timeout value, and using a 'neverending' timeout. There are no other systems (no dual boot), only the options originally installed by default Ubuntu 12.04 installation. My /etc/default/grub has only these effective options: GRUB_DEFAULT='Ubuntu' GRUB_HIDDEN_TIMEOUT=1 GRUB_HIDDEN_TIMEOUT_QUIET=true GRUB_TIMEOUT=1 GRUB_DISTRIBUTOR=`lsb_release -i -s 2> /dev/null || echo Debian` GRUB_CMDLINE_LINUX_DEFAULT="quiet splash" GRUB_CMDLINE_LINUX="" GRUB_TERMINAL=console I experimented with GRUB_DEFAULT, giving it values '0', '1', 'Ubuntu' but nothing helps. Yes I always run update-grub afterwards. How can I make the system booting again ?

• Wifi function key not working on HP laptop

  - by lopsided98

  I have an HP Pavilion g7-1260 with Ubuntu 13.10 on it. I would like to be able to use the wifi toggle key on the keyboard to enable and disable wifi. My wifi works fine and the light on the key turns on when I enable wifi through the Ubuntu networking menu. The problem is that pressing the key does not do anything. It should be activated when I press fn + f12. I tried using xev to see if an event was generated but there wasn't one. I also tried the same thing with apci_listen but it didn't output anything. Does anyone know how to get the key to work?

• How do I EFI boot Zenbook Prime UX31A from built-in card reader?

  - by Richard Ayotte

  How do I EFI boot Zenbook Prime UX31A from built-in card reader? Ubuntu 12.10 64bit has been copied onto an a SD card which I'm trying to boot from. When I power on my Zenbook and press ESC, the SD card isn't an option. There is an "Add boot option" in the BIOS but it requires a few a things that I'm not quite sure of. Add boot option - I guess any identifier works here. I've been entering ubuntu. Select Filesystem - The only option available is PCI(1F|2)\DevicePath(Type 3, SubType 12)HD(Part1,Sig787e6287-xxxx-xxxx-xxxx-xxxxxxxxxxxx) Path for boot option - I've been entering ubuntu:\EFI\BOOT\BOOTx64.EFI Then I select Create and the new boot option appears in the boot menu but it doesn't work.

• How can I send parameters to a sub-index page?

  - by sirius

  Hello. I have a homepage, for example: www.example.com. There is a url like this: www.example.com/subdirectory/page.php?var1=A&var2=B It's a long url, so I changed it like this: www.example.com/subdirectory/page/A/B as well as I config the .htaccess file: <Files page> ForceType application/x-httpd-php </Files> However, I assume it's also quite long. If the "page.php" change to "index.php", the "page" seems to disappear, just like this: www.example.com/subdirectory/A/B But I don't know how to achieve. Is omitted 'page' possible? How can I just do it? Thanks for your help.

• Detecting extremely fast joystick button presses?

  - by DBRalir

  Is it usually possible for the player to press and release a button within a single frame, so that the game engine doesn't have time to detect it? How do programmers usually handle this situation? Is it even necessary to handle it? Specifically, I am asking about GLFW's joystick input capabilities. I am currently using GLFW to make a game, and I've noticed that keyboard and mouse have callback functions, while joysticks do not. Also, it does not appear to be possible to enable "sticky keys" for a joystick. (I have only recently started using GLFW, so please correct me if I am wrong, as having either of those would solve the problem.)

• Can't boot after power failure - 14.04 - GRUB even doesn't showup

  - by Nateowami

  Packages were updating when somehow the power failed (battery fully charged and power got disconnected). Now it won't boot. It doesn't even get as far as GRUB. The bios says it can't boot and press any key to retry. Fortunately all data is backed up and I can boot a live SD. Now what do I do? Model: Dell Latitude D630 Dual-boots with Windows 7, but since GRUB doesn't show up that's not bootable either. Thanks in advance for any help!

• Not able to suspend or hibernate

  - by Tim

  My Ubuntu 10.10 on my laptop Lenovo T400 is not able to suspend or hibernate. Whenever I click Suspend or Hibernate, the moon LED on the bottom of the lid flashes a few seconds, the screen quickly shows something like "some devices fail to suspend, error 5", and then the moon LED goes off and the display still has ambient light illumination. I suppose in suspend or hibernation state, the display should have no illumination, just like when the laptop is turned off, right? If I press any key, the unlock screen dialogue will pop out. I searched a little on the internet, and installed 'acpi-support' according to some advice but it does not help. Any suggestions to solve this problem? Thanks and regards!

• How do I make Home and End work in PuTTY SSH with fish shell?

  - by endolith

  Years ago, an Ubuntu update broke this and I've never found a solution. I have fish as my default shell. Ubuntu 12.10 Locally (Gnome Terminal), Home and End keys work fine in both fish and bash. When I log in by SSH using PuTTY, then run bash, Home and End work fine inside of bash. However, when I log in by SSH using PuTTY, in the default fish shell, pressing Home key produces [1~ (sometimes erasing the line, sometimes not). When I press End, it produces [4~. How do I get Home and End to work correctly?

• Every 3rd Insert Is Slow On Ms Sql 2008

  - by Chris

  I have a function that writes 3 lines into a empty table like so: INSERT [dbo].[yaf_ForumAccess] ([GroupID], [ForumID], [AccessMaskID]) VALUES (1, 8, 1) INSERT [dbo].[yaf_ForumAccess] ([GroupID], [ForumID], [AccessMaskID]) VALUES (2, 8, 4) INSERT [dbo].[yaf_ForumAccess] ([GroupID], [ForumID], [AccessMaskID]) VALUES (3, 8, 3) For some reason only the third query takes a long time to execute - and with each insert it grows longer. Profiler Image I have tried disabling all constraints on the table - same result. I just can't figure out why the first two would run so fast - and the last one would take so long. Any help would be greatly appreciated. Here is the statistics for a query ran MSSMS: Query: ALTER TABLE [dbo].[yaf_ForumAccess] NOCHECK CONSTRAINT ALL INSERT [dbo].[yaf_ForumAccess] ([GroupID], [ForumID], [AccessMaskID]) VALUES (1, 9, 1) INSERT [dbo].[yaf_ForumAccess] ([GroupID], [ForumID], [AccessMaskID]) VALUES (2, 9, 4) INSERT [dbo].[yaf_ForumAccess] ([GroupID], [ForumID], [AccessMaskID]) VALUES (3, 9, 3) ALTER TABLE [dbo].[yaf_ForumAccess] CHECK CONSTRAINT ALL Stats: Stats

• Add SQL Azure database to Azure Web Role and persist data with entity framework code first.

  - by MagnusKarlsson

  In my last post I went for a warts n all approach to set up a web role on Azure. In this post I’ll describe how to add an SQL Azure database to the project. This will be described with an as minimal as possible amount of code and screen dumps. All questions are welcome in the comments area. Please don’t email since questions answered in the comments field is made available to other visitors. As an example we will add a comments section to the site we used in the previous post (Länk här). Steps: 1. Create a Comments entity and then use Scaffolding to set up controller and view, and add ConnectionString to web.config. 2. Create SQL Azure database in Management Portal and link the new database 3. Test it online!   1. Right click Models folder, choose add, choose “class…” . Name the Class Comment. 1.1 Replace the Code in the class with the following: using System.Data.Entity; namespace MvcWebRole1.Models { public class Comment {    public int CommentId { get; set; }    public string Name { get; set; }      public string Content { get; set; } } public class CommentsDb : DbContext { public DbSet<Comment> CommentEntries { get; set; } } } Now Entity Framework can create a database and a table named Comment. Build your project to assert there are no build errors.   1.2 Right click Controllers folder, choose add, choose “class…” . Name the Class CommentController and fill out the values as in the example below.     1.3 Click Add. Visual Studio now creates default View for CRUD operations and a Controller adhering to these and opens them. 1.3 Open Web.config and add the following connectionstring in <connectionStrings> node. <add name="CommentsDb” connectionString="data source=(LocalDB)\v11.0;Integrated Security=SSPI;AttachDbFileName=|DataDirectory|\CommentsDb.mdf;Initial Catalog=CommentsDb;MultipleActiveResultSets=True" providerName="System.Data.SqlClient" />   1.4 Save All and press F5 to start the application. 1.5 Go to http://127.0.0.1:81/Comments which will redirect you through CommentsController to the Index View which looks like this:     Click Create new. In the Create-view, add name and content and press Create.   1: // 2: // POST: /Comments/Create 3:  4: [HttpPost] 5: public ActionResult Create(Comment comment) 6: { 7: if (ModelState.IsValid) 8: { 9: db.CommentEntries.Add(comment); 10: db.SaveChanges(); 11: return RedirectToAction("Index"); 12: } 13:  14: return View(comment); 15: } 16:    The default View() is Index so that is the View you will come to. Looking like this: 1: // 2: // GET: /Comments/ 3: 4: public ActionResult Index() 5: { 6: return View(db.CommentEntries.ToList()); 7: } Resulting in the following screen dump(success!):   2. Now, go to the Management portal and Create a new db.   2.1 With the new database created. Click the DB icon in the left most menu. Then click the newly created database. Click DASHBOARD in the top menu. Finally click Connections strings in the right menu to get the connection string we need to add in our web.debug.config file.   2.2 Now, take a copy of the connection String earlier added to the web.config and paste in web.debug.conifg in the connectionstrings node. Replace everything within “ “ in the copied connectionstring with that you got from SQL Azure. You will have something like this:   2.3 Rebuild the application, right click the cloud project and choose “Package…” (if you haven’t set up publishing profile which we will do in our next blog post). Remember to choose the right config file, use debug for staging and release for production so your databases won’t collide. You should see something like this:   2.4 Go to Management Portal and click the Web Services menu, choose your service and click update in the bottom menu.   2.5 Link the newly created database to your application. Click the LINKED RESOURCES in the top menu and then click “Link” in the bottom menu. You should get something like this. 3. Alright then. Under the Dashboard you can find the link to your application. Click it to open it in a browser and then go to ~/Comments to try it out just the way we did locally. Success and end of this story!

• Problem with the keyboard layout in Emacs (ubuntu 12.04)

  - by user61648

  I've got some problems with the keyboard layout. I have a french AZERTY keyboard. When I switch to another layout (I tested both programmer DVORAK and Greek) everything seems fine. However, in emacs, I have a more unexpected (at least for me) behavior. For example, in DVORAK, I thought to obtain: On my french Keyboard - DVORAK X - Q Alt-X - Alt-Q But I have: X - Q Alt-X - Alt-X When I press the Alt key, the layout change seems to be inactivated. I precise I didn't activated any shortcut containing the Alt key for the layout switching. Moreover, I'm not sure this behavior is restricted to Emacs, but I don't use shortcuts like Alt-... in another application. Is a such behavior normal ? And in this case, how can I use a shortcut like Alt-Q when I switch to DVORAK ?
