• custom libindicator icon is not displayed

  - by Christoph Sterz

  Hi there, I want to change the statusicon of my own little reminder program. Currently I am using GTK.StatusIcon but I want to use a ApplicationIndicator. Therefore I created an own Icon and moved it to: /usr/share/icons/ubuntu-mono-dark/status/22 It is named indicator-notify.svg Heres the code for the icon. ind = appindicator.Indicator ("notify", "indicator-notify", appindicator.CATEGORY_APPLICATION_STATUS) ind.set_status (appindicator.STATUS_ACTIVE) This Icon is not displayed. Although every other icon from this folder is. What did I miss? Is there maybe the need to "register" the icon in GTK ?

• ODI 11g - Faster Files

  - by David Allan

  Deep in the trenches of ODI development I raised my head above the parapet to read a few odds and ends and then think why don’t they know this? Such as this article here – in the past customers (see forum) were told to use a staging route which has a big overhead for large files. This KM is an example of the great extensibility capabilities of ODI, its quite simple, just a new KM that; improves the out of the box experience – just build the mapping and the appropriate KM is used improves out of the box performance for file to file data movement. This improvement for out of the box handling for File to File data integration cases (from the 11.1.1.5.2 companion CD and on) dramatically speeds up the file integration handling. In the past I had seem some consultants write perl versions of the file to file integration case, now Oracle ships this KM to fill the gap. You can find the documentation for the IKM here. The KM uses pure java to perform the integration, using java.io classes to read and write the file in a pipe – it uses java threading in order to super-charge the file processing, and can process several source files at once when the datastore's resource name contains a wildcard. This is a big step for regular file processing on the way to super-charging big data files using Hadoop – the KM works with the lightweight agent and regular filesystems. So in my design below transforming a bunch of files, by default the IKM File to File (Java) knowledge module was assigned. I pointed the KM at my JDK (since the KM generates and compiles java), and I also increased the thread count to 2, to take advantage of my 2 processors. For my illustration I transformed (can also filter if desired) and moved about 1.3Gb with 2 threads in 140 seconds (with a single thread it took 220 seconds) - by no means was this on any super computer by the way. The great thing here is that it worked well out of the box from the design to the execution without any funky configuration, plus, and a big plus it was much faster than before, So if you are doing any file to file transformations, check it out!

• 0.00006103515625 GB of RAM. Is .NET MicroFramework part of Windows CE?

  - by Rocket Surgeon

  The .NET MicroFramework claims to work on 64K RAM and has list of compatible targets vendors. At the same time, same vendors who ship hardware and create Board Support Packages (vendors like Adeneo) keep releasing something named Windows 7 CE BSP for the same hardware targets. Obviously the OS as heavy as WinCE needs more than 64K RAM. So, somehow .NET MicroFramework is relevant to WinCE, but how ? Is it part of bigger OS or is it base of it, or are both mutually exclusive ? Background: 0.00006103515625 GByte of RAM is same as 64Kbyte of RAM. I am looking for possiblity to use Microsoft development tools for small target like BeagleBone. http://www.adeneo-embedded.com/About-Us/News/Release-of-TI-BeagleBone Nice. Now .. where is a MicroFramework for the same beaglebone ? Is it inside the released pile ?

• Importing 3d model with multiple skeletons

  - by Sweta Dwivedi

  I have created an animated butterfly in 3ds Max and try to export it in ".fbx" format to use in XNA, however as soon as I compile, i get the following Errors: Warning 1 Multiple skeletons were found in the file. The first skeleton, named "Left.Wing" has been moved to be a child of the scene root. The other, "Right.Wing", will be ignored. Fragment identifier "Right.Wing". Error 2 Vertex is bound to bone "Right.Wing", but this bone is not present in the skeleton. Which is confusing since I have the bone Right.Wing . . and I use it to animate the butterfly I have seen a few possible solution for Blender but none for 3Ds max it would be really helpful if someone could help me out with this

• Folder Permissions for new partition - can't move files

  - by user292743

  I'm using Ubuntu 14.04. I used the install CD to repartition my HD by resizing /dev/sda1 and creating /dev/sda3 as a Primary Partition. I named it "Media". When I reboot from HD, when I try to move files from the home directory to the new partition, I get an error message "Error while copying. The folder “TV” cannot be copied because you do not have permissions to create it in the destination." The new partition shows up in Gparted as locked, with mount point /media/ian/Media and Label Media. I want to move my media files from the boot partition to a separate partition. Any advice?

• JavaFX Makeover for JFugue Music NotePad

  - by Geertjan

  Bengt-Erik Fröberg from Sweden, one of the developers working on ProSang, the leading Scandinavian blood bank system (and based on the NetBeans Platform), is reworking the user interface of the JFugue Music NotePad. In particular, the Score window (named ScoreFX window below) contains components that are now quite clearly JavaFX, instead of Swing. Looks a lot better and also performs better. The sliders in the Keyboard window are candidates for being similarly redone to use JavaFX instead of Swing. Want to do something similar? Here's all the info you need: http://platform.netbeans.org/tutorials/nbm-javafx.html

• Stopping duplicate H1 and title from dynamic content

  - by codemonkey

  I have a web site where there are lots of dynamically (database driven) created pages. These pages are basically used to show uploaded images The pages look a bit like this URL: http://www.mywebsite.com/page-id/page-title/ H1: View from the sea This is a big issue because I might have 10 other pages with the title: 'View from the sea'. I know the simple solution would be to make sure the pages are named differently but I have lots of users on the web site so it's not that simple. What do you guys think to putting the page-id with the page-title in the H1 tag? So it might read 437 - View from the sea. I need to differentiate the h1 titles. I think using the page-id would help but if anyone has a better solution that would be great! Thanks in advance

• Boot-up hangs unless I manually select the kernel in the bootloader

  - by The Photon

  In my stock Ubuntu install (forgot which critter its named for, about one year old), I am able to boot up normally only if I manually select the kernel in the bootloader (Grub). If I step away and it boots from the default, the system will hang with the word "Ubuntu" on a graphics screen and a few white/red blinking dots beneath it. umb@digdug:~$ uname -a Linux digdug 2.6.32-42-generic #95-Ubuntu SMP Wed Jul 25 15:57:54 UTC 2012 i686 GNU/Linux Synaptics says I have 'grub-pc' version 1.98-1ubuntu-13 installed. My grub.cfg does have default="0" which I would expect to make the default be the first kernel shown in the selection screen. The system is a laptop with an i7 processor, and I have had trouble with some kernels not being able to boot at all in the past, and power management is not working perfectly, but I have not had problems booting the latest kernel (2.6.32-42) if I select it manually in Grub. Any idea what is going on here and how can I fix it so that I can re-boot unattended?

• Per-vertex animation with VBOs: Stream each frame or use index offset per frame?

  - by charstar

  Scenario Meshes are animated using either skeletons (skinned animation) or some form of morph targets (i.e. per-vertex key frames). However, in either case, the animations are known in full at load-time, that is, there is no physics, IK solving, or any other form of in-game pose solving. The number of character actions (animations) will be limited but rich (hand-animated). There may be multiple characters using a each mesh and its animations simultaneously in-game (they will be at different poses/keyframes at the same time). Assume color and texture coordinate buffers are static. Goal To leverage the richness of well vetted animation tools such as Blender to do the heavy lifting for a small but rich set of animations. I am aware of additive pose blending like that from Naughty Dog and similar techniques but I would prefer to expend a little RAM/VRAM to avoid implementing a thesis-ready pose solver. I would also like to avoid implementing a key-frame + interpolation curve solver (reinventing Blender vertex groups and IPOs). Current Considerations Much like a non-shader-powered pose solver, create a VBO for each character and copy vertex and normal data to each VBO on each frame (VBO in STREAMING). Create one VBO for each animation where each frame (interleaved vertex and normal data) is concatenated onto the VBO. Then each character simply has a buffer pointer offset based on its current animation frame (e.g. pointer offset = (numVertices+numNormals)*frameNumber). (VBO in STATIC) Known Trade-Offs In 1 above: Each VBO would be small but there would be many VBOs and therefore lots of buffer binding and vertex copying each frame. Both client and pipeline intensive. In 2 above: There would be few VBOs therefore insignificant buffer binding and no vertex data getting jammed down the pipe each frame, but each VBO would be quite large. Are there any pitfalls to number 2 (aside from finite memory)? Are there other methods that I am missing?

• Can't (re)install lazarus

  - by twice

  I had Lazarus installed (from website, not USC), while upgrading to 13.10 and after that, it posted some error message (which I can't remember) at every start. I decided it shouldn't suffer, so I started reinstalling it, but it didn't work. then I thought I'll start all over, and deleted and purged everything. But it still would not install. I found a similar, very similar question to mine here: Cant correctly install Lazarus I tried everything said there: sudo dpkg -l | grep "^rc" returned some packages: since sudo apt-get -f brought up the apt-get help message, and sudo apt-get -f install did nothing, I went ahead and manually purged every broken package, which seemed to bring me forward, since it removed the entries in sudo dpkg -l | grep "^rc". When I was done I tried it again, since it didn't work I rebooted, no change. this is the error message I get on the attempt to install the first package (fpc-2.6.2): root@Someone-PC:~# dpkg -i /home/someone/Desktop/fpc_2.6.2-0_amd64\ \(3\).deb (Reading database ... 242209 files and directories currently installed.) Unpacking fpc (from .../fpc_2.6.2-0_amd64 (3).deb) ... dpkg: error processing /home/someone/Desktop/fpc_2.6.2-0_amd64 (3).deb (--install): trying to overwrite '/usr/lib/fpc/2.6.2/msg/errores.msg', which is also in package fp-compiler-2.6.2 2.6.2-5 dpkg-deb: error: subprocess paste was killed by signal (Broken pipe) Errors were encountered while processing: /home/someone/Desktop/fpc_2.6.2-0_amd64 (3).deb So, how can I fix this?

• Asking about deleted partition at boot

  - by Shawn Mitchell

  I have Ubuntu installed through Wubi. I also had another partition on my computer to try out the dev preview of Windows 8 aptly named Windows_8. After I was done playing, I deleted the Windows 8 partition and added the extra space back to my Win7/Wubi partition. Now every time I boot into Ubuntu, it tells me that it can't mount the partition and asks me if I want to recover or skip it. Is there a way to get Ubuntu to forget about this partition so I can skip this extra step in my boot? Thanks

• xorg-edgers PPA with llvmpipe breaks AMD APU system

  - by linux_RRT

  I've read before where this had happened to another user with the same system... I was running Ubuntu 12.04 LTS with Kernel 3.2.0.29 and decided to give xorg-edgers a try. I purged fglrx* and xorg* before beginning. I upgraded with sudo apt-get upgrade -d The system downloaded and installed 109MB worth of data to the system, including llvmpipe which I am very unfamiliar with, and Kernel 3.5.0.11. The system was then rebooted to finalize the upgrade. The system boots to a black screen and then tells me "The system is running in low-graphics mode". Did I miss a step in the install? Or do the newest open-source drivers just not work with my hardware? I realize this hardware (APU) is some of the newer development. I dropped to command via the fallback menu and attempted to boot lightdm as root, but the system hangs in 'Configuring kernel parameters' at Starting initializes zram swaping. ...and then it just sits there. The other thing that concerns me is the output at the top of the screen that says: could not write bytes: Broken pipe Does llvmpipe work for this type of system? To be clear the system is: MSI x370-206us Laptop Radeon HD 6320 AMD e450 APU 1.67ghz dual-core Any help would be much appreciated. Like I said, I'm pretty sure I followed the right order of operations for the install procedure, but I was curious if anyone with similar hardware had experienced anything similar.

• How can I exclude content in my notifications bar from being indexed?

  - by Liam E-p

  Of course I want my content to be indexed pretty fast by search engines, however not my notifications bar. My notifications bar contains the last 30 changes to content on the site, and I don't want this to show in my SEO meta. As all the notifications are generic, it often doesn't provide any relevant information. As I said the notifications are generic. If an article named "123" was created, it would create a notification that says "Article "123" was created by xxx at 12:00AM". I'm now wondering if this is a content design problem. As only 1/3 of this information is actually relevant to users (the title, what happened). By SEO meta, and irrelevant notification data being shown, I mean this - Basically what I was wondering, is how I could optimise this, so search engines wouldn't show this generic nonsense.

• 6 Great Alternative Browsers for Your Android Device

  - by Chris Hoffman

  Android’s default browser, named “Internet,” is a very simple browser that’s tied to your Android OS version. Other, third-party browsers offer more powerful interfaces, greater configurability, and more frequent updates. Unlike on Apple’s iOS, Android browsers can implement their own rendering engines, although not all do. That Firefox app isn’t just a shell over the stock browser, like it is on iOS – it brings Mozilla’s Gecko to Android.

• WebLogic Application Server: free for developers!

  - by Bruno.Borges

  Great news! Oracle WebLogic Server is now free for developers! What does this mean for you? That you as a developer are permited to: "[...] deploy the programs only on your single developer desktop computer (of any type, including physical, virtual or remote virtual), to be used and accessed by only (1) named developer." But the most interesting part of the license change is this one: "You may continue to develop, test, prototype and demonstrate your application with the programs under this license after you have deployed the application for any internal data processing, commercial or production purposes" (Read the full license agreement here) If you want to take advantage of this licensing change and start developing Java EE applications with the #1 Application Server in the world, read now the previous post, How To Install WebLogic Zip on Linux!

• Should you put personal beliefs in your program?

  - by TheLQ

  Recently I've found two examples of programmer's personal beliefs in programs that have removed or crippled useful functionality uTorrent using KB (rarely used) vs Kb (what most ISPs and other programs use as their metric) in their current connection speed. Various attempts by others and me to give options to at least give an option to show in Kb have ended with "ISPs should use KB" Kleopatra (gpg4Win key manager) not having PGP Key Pictures since they "give a false sense of security" and "increase the size of certificates". While the latter is true, the former is debatable. Both of these hurt the program and its usefulness to me. uTorrent's forums used to be filled with people saying they have 10 Mb download pipe but uTorrent only goes up to 2 MB (not knowing that Mb != MB), and with feature requests to show in Mb. Kleopatra has lost usefulness to me since I don't have the functionality to add pictures to PGP keys. These all are political statements; developers attempting to make change in, in their minds important, issues. But should this come at a cost to end user functionality? If a programmer heavily believes X but everyone else believes Y, should the programmer refuse to add support for Y because in their mind X is horrible? In short, should a programmer make political statements in their program?

• What do you do when your naming convention clashes with your language?

  - by Jon Purdy

  Okay, this is one of those little things that always bugged me. I typically don't abbreviate identifiers, and the only time I use a short identifier (e.g., i) is for a tight loop. So it irritates me when I'm working in C++ and I have a variable that needs to be named operator or class and I have to work around it or use an abbreviation, because it ends up sticking out. Caveat: this may happen to me disproportionately often because I work a lot in programming language design, where domain objects may mirror concepts in the host language and inadvertently cause clashes. How would you deal with this? Abbreviate? (op) Misspell? (klass) Something else? (operator_)

• problems with studying algorithms

  - by rookie

  hello everyone, I'm currently studying computer science at the Institute, and I have some problems with course which is named Algorithms, I've just begun to study it, but I'm already feeling, that I'm going to fail it, my problem is that while understanding different algorithms on graphs I need to keep in my mind a lot of info, and usually I can't do it, I forget some points of the exercise or can't proceed to final result, I'm very desperate about it cause I like programming very much. Did somebody feel the same while studying in the University? thanks in advance for any help P.S. I began to program only two years ago, may it be the problem?

• VirtualBox and Ubuntu Mount Error

  - by skaz

  I have Ubuntu 10 as the guest OS on a Windows 7 machine. I have been trying to setup shares through VirtualBox, but nothing is working. First, I create the share in VirtualBox and point it to a Windows folder. Then I try to mount the drive in Linux, but I keep getting /sbin/mount.vboxsf: mounting failed with the error: Protocol error I have read so many solutions to this, but none seem to work. I have tried: Using the mount.vboxsf syntax Reinstalling VBox additions Rebooting Enabling and trying as root account Any other ideas? In case I am doing something dumb, here are more details: I made a share called "Test" in VBox Shared folders. Then I made a directory in ubuntu named "test2". Then I tried to execute this command: sudo mount -t vboxsf Test /mnt/test2 Thank you!

• Picture lens doesn't find anything

  - by Han Cnx

  I get Facebook results, but nothing from my computer. If I open a terminal and use 'locate' then I can find stuff, but the picture lens is empty. Note that my picture files are on an NTFS partition. I have made a link named 'Pictures' in my home folder that points to the location where the picture files are. Again, this works with the 'locate' command and it also works for the Music lens, which is also a link in my home folder. It also (kinda) works for the Video lens, though it only wants to find videos I have opened, which seems not consistent with the other lenses. (and also not very useful this way)

• forbidden foldername?

  - by j0h

  I have a little webserver i run to help me at work. in an effort to neaten up the internal bits, I made a forlder named "doc" for documents. When i try to navigate to that folder i get "You don't have permission to access /doc/ on this server." so then, i looked at the permissions. drwxrwxr-x 2 J0h J0h 4096 Nov 7 22:46 doc/ drwxrwxr-x 5 J0h J0h 4096 Nov 6 12:35 ece/ drwxrwxr-x 2 J0h J0h 4096 Nov 6 12:35 exe/ permissions of "doc" looks legit. ece/ and exe both work, and have the same permissions. So then I changed the name of the folder "doc" to "docs" and it works. So evidently the folder-name doc is a black listed folder name? is that right? what is going one here?

• HP 6735s Brightness hotkey problem; where is brightness panel?

  - by Paul

  I have installed ubuntu 11.10 on my laptop hp 6735s. The screen is often too dark and i want to make it brighter, although the hotkeys Fn+F7/F8 are not working. I have tried some things: Firstly it appears that sometimes they are in fact working, after reboot they either work and continue to do so or they don't. I've read about a brightness applet; but where can i find or install it? I have tried some grub options; acpi_osi=Linux and acpi_backlight=vendor but nothing changes. I don't want to add another question but since it might be related: my laptop also gets quite hot, i'm having doubts whether ubuntu connects to the available sensors and cooling plans (or how does it work???); sensors (or psensor) only shows 2 sensors both named temp1. Any help is greatly appreciated! Paul
