  • How to re-enable tray icons for applications in ubuntu 13.10?

    - by andraaska
    Unfortunately in new Ubuntu 13.10 there is no Tray Icon and Whiteliting is removed. The older solutions are not works for me, e.g.: No such schema 'com.canonical.Unity.Panel' message answered when I try to use the gsettings set com.canonical.Unity.Panel systray-whitelist "['all']" comand. How can I get tray icons back (for applications that put icon in tray like Truecrypt, Pidgin, Aqualung, gnome-system-monitor, gyache, and so many more...) in Unity ? The most annoying is that the user loses control over applications can not detect itself that it has no tray icon... (e.g.: gnome-system-monitor, truecrypt...) At least Aqalung send a message about unable to put icon on systray! Thanks

  • Looking for bug tracking software

    - by Shelton
    I'm looking for a bug/issue tracking system that can: Integrate with lots of other services. Basecamp, Beanstalk, etc. Integrate popular CMSs, such as WordPress, so the client can enter a ticket from the system that is familiar to them and not have one more login to worry about. Generate reports for my own purposes. Bonus if there's an iPhone app. Doesn't require additional development on my end (I have plenty of money and no time). I've already looked into Lighthouse and ZenDesk -- both are solid offerings -- but don't see what I need out of the box. I'd have to build CMS plug-ins. And I've looked through WP plug-ins for bug tracking software, but nothing I've found integrates with these products. Anyone know of something that meets these requirements without additional development, or am I stuck putting my business on hold to get this piece in place myself?

  • Operating on rows and then on columns of a matrix produces code duplication

    - by Chetan
    I have the following (Python) code to check if there are any rows or columns that contain the same value: # Test rows -> # Check each row for a win for i in range(self.height): # For each row ... firstValue = None # Initialize first value placeholder for j in range(self.width): # For each value in the row if (j == 0): # If it's the first value ... firstValue = b[i][j] # Remember it else: # Otherwise ... if b[i][j] != firstValue: # If this is not the same as the first value ... firstValue = None # Reset first value break # Stop checking this row, there's no win here if (firstValue != None): # If first value has been set # First value placeholder now holds the winning player's code return firstValue # Return it # Test columns -> # Check each column for a win for i in range(self.width): # For each column ... firstValue = None # Initialize first value placeholder for j in range(self.height): # For each value in the column if (j == 0): # If it's the first value ... firstValue = b[j][i] # Remember it else: # Otherwise ... if b[j][i] != firstValue: # If this is not the same as the first value ... firstValue = None # Reset first value break # Stop checking this column, there's no win here if (firstValue != None): # If first value has been set # First value placeholder now holds the winning player's code return firstValue # Return it Clearly, there is a lot of code duplication here. How do I refactor this code? Thanks!

  • Very frequent system problems since 12.10 upgrade

    - by Jazz
    Since I recently upgrade my 12.04 install to 12.10, there is loads more instability generally. I have captured just the latest example - often occurring just after startup and login. Other random times, similar things happen - not always the same executable is reported - might be many different problems. Is everyone finding 12.10 a bit unstable (in which case I can hope for fixes to filter through over the coming months)?

  • Writing a dynamic achievement system without hardcoding rules into the application

    - by imaginative
    I really enjoyed the solution provided here for groundwork on writing an achievement framework. The problem I have is I have game designers that would like to be able to insert achievements into a CMS at runtime. In a way, it sounds insane and complex to do this, but is it really? I think the concept of having to do a hard push of the application for every new achievement is cumbersome. I would love to be able to give our designers the capability to put together new achievements by entering them into a database. It shouldn't matter what tool I'm using, but for those interested, my backend is being written in JRuby (Ruby on top of the JVM). What are some possible ways of going about abstracting the logic in the aforementioned link even further so that rules can be interpreted at runtime?

  • Unable to use certain Fonts programatically in ASP.Net

    - by TooFat
    I am trying to programatically create a bitmap with a specified font in ASP.Net. The idea is that the text, font name, size color etc. will be passed in from variables and a bitmap of the text using the font etc will be returned. However, I have been finding that I am only able to do so using the following code with certain fonts. <div> <% string fontName = "Segoe Script"; //Change Font here System.Drawing.Bitmap bmp = new System.Drawing.Bitmap(100, 100); System.Drawing.Graphics graph = System.Drawing.Graphics.FromImage(bmp); System.Drawing.Font fnt = new System.Drawing.Font(fontName, 20); System.Drawing.SolidBrush brush = new System.Drawing.SolidBrush(System.Drawing.Color.Red); graph.DrawString("Help", fnt, brush, new System.Drawing.Point(10, 10)); bmp.Save(@"C:\Development\Path\image1.bmp"); this.Image1.ImageUrl = "http://mysite/Images/image1.bmp"; %> <asp:Label ID="Label1" runat="server" Text="Label" Font-Names="Segoe Script"> <%Response.Write("Help"); %></asp:Label> //Change font here <asp:Image ID="Image1" runat="server" /> </div> If I change the font name in the areas indicated by the comments to Arial or Verdana both the image and the label appear with the correct font. If however, I change the font name in both locations to something "Segoe Script" the Label will show up in Segoe Script but the image is in what looks like Arial.

  • How to use Eclipse and versioning for a matrix of projects

    - by Nulldevice
    Our company develop several software products, which reuse each others packages (we use Java). Every product represented as separate Eclipse Java project and has it's own versioning repository (we use Mercurial). When we find a bug in some shared package, we need to transfer changes to all consuming projects, and this is a hell. The key problem is that Eclipse project can be associated only with one versioning repository. Could someone recommend some way to associate Eclipse Java project whith several versioning repositories which in ideal may be geterogeious (svn, git, mercurial) ?

  • The ETL from Hell - Diagnosing Batch System Performance Issues

    Too often, the batch systems that underlie a lot of database processing just grow without conscious design. When runs start to extend beyond their allotted time, and tuning no longer solves the problem, it is often discovered that batches are run in series, with draconian error handling. It is time to impose some rational design, and Nigel is a seasoned healer of batch processes.

  • System hangs at glReadPixel call with GL_TEXTURE_2D_ARRAY for texturing

    - by Roshan
    I am calling glReadPixel after glDrawArray call. I am rendering a geometry with 3D texture on it as a target GL_TEXTURE_2D_ARRAY. My systems hangs at glreadpixel call. When i use target as GL_TEXTURE_3D the issue does not occurs and it correctly reads the framebuffer contents. glReadPixels(0, 0, GetViewportWidth(), GetViewportHeight(), GL_RGBA, GL_UNSIGNED_BYTE, (GLvoid *)rendered_pixels); I am using SNORM textures with GL_byte data in glTeximage3D call and I am not calling glPixelStorei, is it because of this? What should be the parameter for pixelstore call?

  • Five years old Ubuntu system - dist-upgrades always went fine, however some tasks remain

    - by knb
    I have a PC with a current Ubuntu distribution installed. I've upgraded many times since 5.10. It always went well, however some tools or features were kind of left behind in a unsatisfactory state: grub to grub2 - is it an really necessary to switch the boot loader some time to grub2. Upgrading this scares me abit. I still have ext3 devices - is it worth upgrading to ext4? should I wait for btrfs? hibernation and suspend- it only worked in 5.10, since 6.04 it was messed up. Should I really care? Any chance to repair this myself? Simply by cleanup or hacking config files. It is a desktop PC after all. So energy saving functionality is not really needed. I am using vmware workstation 6.5 and the latest kernel that supports it is 2.6.32. This is my default kernel now, ignoring 2.6.35. Am I missing anything important in the new kernel now?

  • Models from 3ds max lose their transformations when input into XNA

    - by jacobian
    I am making models in 3ds max. However when I export them to .fbx format and then input them into XNA, they lose their scaling. -It is most likely something to do with not using the transforms from the model correctly, is the following code correct -using xna 3.0 Matrix[] transforms=new Matrix[playerModel.Meshes.Count]; playerModel.CopyAbsoluteBoneTransformsTo(transforms); // Draw the model. int count = 0; foreach (ModelMesh mesh in playerModel.Meshes) { foreach (BasicEffect effect in mesh.Effects) { effect.World = transforms[count]* Matrix.CreateScale(scale) * Matrix.CreateRotationX((float)MathHelper.ToRadians(rx)) * Matrix.CreateRotationY((float)MathHelper.ToRadians(ry)) * Matrix.CreateRotationZ((float)MathHelper.ToRadians(rz))* Matrix.CreateTranslation(position); effect.View = view; effect.Projection = projection; effect.EnableDefaultLighting(); } count++; mesh.Draw(); }

  • How to test reliability of my own (small) embedded operating system ?

    - by TridenT
    I've written a small operating system for embedded project running on small to medium target. I added some automated unit test with a high test code coverage (95%), but the scope is only the static part. I got some code metrics as complexity and readability. I'm testing my code with a rule checker with MiSRA support, and of course fixed all warnings. I'm testing the code with a static analyzer and again fixed all warnings. What can I do now to test - and improve - the reliability of my OS ? How about the dynamic part ?

  • System checks for disk drive error every time it boots

    - by Starx
    When my disk space for the ubuntu installation partition was getting low, from a live cd, I used gparted to increase its volume capacity, but deleting another partition and merging it to the ubuntu partition. Since then onwards, I am receiving disk checking for errors at boot screen for my partitions, always. What seem to be causing this and how to fix it? Update Here is my boot.log if it provides few insight fsck from util-linux 2.19.1 fsck from util-linux 2.19.1 /dev/sda1 was not cleanly unmounted, check forced. ubuntu: clean, 501325/1310720 files, 2958455/5242880 blocks /dev/sda1: 241/51272 files (3.3% non-contiguous), 73541/102400 blocks mountall: fsck /boot [358] terminated with status 1 Skipping profile in /etc/apparmor.d/disable: usr.bin.firefox ... /dev/sda1 is a separate grub partition for my dual OS's

  • What do gurus say about Requirements Traceability Matrix?

    - by Jaywalker
    Our organization is at CMMI Level 2, and as part of the requirements of the level, we have to maintain an RTM which more or less contains the following entries for each requirement: Requirement Description Reference Section Functional Specification Document Reference Section Design Document Reference Section Test Cases Document Now, this might be an overkill for a small project. But more importantly, this could be a nightmare to maintain when the requirements/ features keep changing, and documents have to be constantly updated. What do the gurus say about this? Should one avoid such level of documentation or are there any tools to manage when a "change" out dates so many artifacts? And by using the term 'gurus', I am not talking of coding champs; rather people like Steve McConnel or others who have worked on commercial projects of medium to large scale. Quotes/ book references/ articles will suit me. EDIT: It's not just requirements that change. Design Document can change; well, even test cases may change.

  • Aide On a Low Memory System

    - by Jason Mock
    I have a Linux server running on a Linode.com VPS, where I'm trying to utilize aide to detect any issues. However, the nightly aide run uses up all of my available memory and swap (512MB RAM / 384MB SWAP). I've tried adding a script to /etc/cron.daily that would stop/start services using a lot of memory (apache2, mysql) during the aide run. Unfortunately, it seems like aide continued to use every available byte (including the space freed up from apache2 and mysql). Here's a graph from munin showing what happens when aide runs: Note the spike of memory usage, well into swap, when aide runs Any suggestions on tuning aide to not use so much memory, or is there an alternative to aide that doesn't behave this way?

  • Fusion-Icon does not show up in system tray

    - by Schubibuntu
    I can't find a solution for my problem online: I'm running Unity 2D in Ubuntu 11.10 and want to enable compiz effects. I installed compiz config settings manager, and Fusion-Icon, but when I start Fusion-Icon nothing happens. When I execute it from terminal it stucks at lines like "setting update 'command'" or "setting update 'next_key'" I already set the whitelist for the panel to 'all'. Anyone knows what I'm missing? Thanks in advance!

  • ILNumerics multiply complex with matrix<double>

    - by nik
    I m looking at ILNumerics to translate some matlab code into c#. How would I multiply a complex and a double? Simplified description: In Matlab: A=[1 2 3] i*A*A' Returns a complex number. How would I do the same in ILNumerics: ILArray<double> A = ILMath.array(1.0, 2.0, 3.0); complex B = complex.i * ILMath.multiply(A,A.T); Throws the error: Operator '*' cannot be applied to operands of type 'ILNumerics.complex' and 'ILNumerics.ILRetArray<double>' Update This works: double C = 14.0; complex D = complex.i * C; But shouldnt: ILMath.multiply(A,A.T) also return 14.0?

  • System beeps on shutdown

    - by Nicholas Smith
    Very recently a couple of our systems have started making beeps on shutdown, we've not been able to isolate the exact time that they've been updated and it's occuring, but I've narrowed it down to being not pcspkr or snd_pcsp as both are blacklisted under modprobe, and rmmod'ed just to be sure. Now I'm a bit puzzled as I was under the impression those were the only two modules that could make the beep, is there a third lurking that I need to blacklist? Edit: I've copied the results of lsmod over on Pastebin.
