• Syncing my iPod Touch (And Others)

  - by Benjamin Hannah

  libimobiledevice doesn't work for me. I've got Ubuntu 11.10 and I'm trying to put music on to my iPod Touch 4Gen running iOS 5.0.1. I have tried every program available in the Ubuntu software center for sycing iPods and I get basically the same response from each one: "[cannot apply changes etc, ect, etc]" I've tried rigorously with Banshee and Rythmbox with no success. I've even tried running iTunes on Windows XP in VirtualBox with no success. I've tried running iTunes through Wine and it results in an error message saying something along the lines of "[Please install Apple Application Support and then reinstall iTunes]". I am considering Jailbreaking my iPod but I cannot find Absinthe that works with my iPod and with Ubuntu. In addition I'm not sure how ** works with Ubuntu. I'm really in a pickle here. It would be ever so helpful if I could indeed have some help with this issue.

• How to prevent WLAN connection from dropping permanently on a Fritz USB WLAN N stick?

  - by Chris

  I have a desktop with a Fritz USB WLAN N stick and tried Ubuntu 12.04. Installation went fine and WLAN is working. However, connection drops permanent. Reconnecting manually fixes it but after a few minutes it drops again. It's connected to a Vodafone 802 box with WLAN N fix set. It seems that it works when I switch off N mode. But I need to test. Can someone confirm this issue or is there another solution? I have another machine with 12.04 (HP 625 laptop) running where connection is stable.

• Unity3D: default parameters in C# script

  - by Heisenbug

  Accordingly to this thread, it seems that default parameters aren't supported by C# script in Unity3D environment. Declaring an optional parameter in a C# scirpt makes Mono Ide complaint about it: void Foo(int first, int second = 10) // this line is marked as wrong inside Mono IDE Anyway if I ignore the error message of Mono and run the script in Unity, it works without notify any error inside Unity Console. Could anyone clarify a little bit this issue? Particularly: Are default parameters allowed inside C# scripts? If yes, are they supported by all platforms? Why Mono complains about them if the actually works?

• How can I refactor client side functionality to create a product line-like generic design?

  - by Nupul

  Assume the following situation similar to that of Stack Overflow: I have a system with a front-end that can perform various manipulations on the data (by sending messages to REST back-end): Posting Editing and deleting Adding labels and tags Now in the first version we created it well modularized but the need as of now for 'evolving' the system similar to Stack Overflow. My question is how best to separate the commonality and how to incorporate the variability with respect to the following: Commonality: The above 'functionalities' and sending/receiving the data from the server Look and feel (also a variability as explained below) HTTP verbs associated with the above actions Variability: The RESTful URLs where the requests are sent The text/style of the UI (the commonality is analogous to Stack Overflow - the functionality of upvotes, posting a question remains the same, but the words, the icons, the look and feel is still different across sites) I think this is entirely a client-side code organization/refactoring issue. I'm heavily using jQuery, javascript and backbone for front-end development. My question is how best should I isolate the same to be able to create multiple such aspects to the tool we are currently working on?

• Maximized Office 2007 gets cut off on multi-monitor setup with different resolutions

  - by Adam M-W

  I've got an external monitor plugged into my laptop that I like to use for typing up documents, but I've noticed that when Word is maximized it gets cut off at where the primary monitor's bounds are. Is this a bug in Wine (i'm using version 1.3.32), or with my Window Manager (metacity with compositing enabled, version 2.34.1), with my graphics drivers (nouveau) or something else? I know that I can fix it by unmaximizing (it doesn't get cut off and I can resize to the entirety of the second monitor), but it keeps on maximizing itself as it (rightly so) knows that it should be taking up the entire screen. I don't really want to use the "Emulate a virtual desktop feature", I would prefer to find the source of this issue.

• What is the Policy for Updating grub-pc in LTS?

  - by nutznboltz

  After having attempted an SRU request for a small patch to grub-pc for 10.04 LTS that fixes an issue that has left many people with unbootable servers nothing has been done for some time. The patch went through d-i into Maverick and only modifies a small amount of a single *.c file over a year ago. I updated the ticket with a debdiff of the patch and rebuilt the current grub-pc package plus the patch in a PPA and changed the ticket description to be the SRU request format subscribed the "sru" and "sponsors" teams but then nothing happened. Is there some policy against updating grub-pc in LTS that I don't know about? Thanks.

• WordPress bot issues

  - by Paul

  I need to implement a blog into a clients site as he is unhappy with his current basic CMS driven solution. It needs to suit both seo and the current style and as I'm a front end dev/designer and they don't have budget to redevelop - the only solution I can think of is to setup a Wordpress blog and restyle to suit. My only worry about this is the current press reports on WordPress being affected by webbots. I understand the main worry Is if you use an id of admin, but I'm concerned that regardless of this the site could be bombarded with bot requests and cause timeouts! Is this valid? If so is there any way to avoid this issue!? If not can anyone recommend another good SEO friendly blog solution!?

• Uploading a file automatically for speed test?

  - by Abhi

  I am building a Web UI for a device for internet connection and one of the requirements in it is a speed test. I know the basic concept of how speed test works. A file is downloaded for a limited time then the same file is uploaded again and the speed is tracked at regular intervals. Downloading the file is not an issue, but how am I supposed to upload the file without the client knowing that the file is getting uploaded? I've read through a lot of documentation, but I'm still not able to get the answer to how I will upload the file from clients machine without asking him to select the file.

• Grub-Efi wrong resolution

  - by Nikki Kononov

  My question, as it comes from the title, related to grub, but it's a different thing. I re-installed Windows 7 and Ubuntu 12.10 in UEFI mode (before that I was using normal BIOS) and everything went perfectly fine. Both systems load as they should but there is one thing that keeps bothering me. The problem is before I installed both systems in UEFI I used to boot in both system using common grub (non-uefi) and resolution in this grub was correct (which is 1366x768). Right now with grub-efi I have wrong resolution (which is seems to be 640x480). So my question is can can I safely set grub-resolution using grub config files or issue is related to something else? (for instance graphics card). I am using Ubuntu 12.10 Intel HD 3000 + Nvidia GT 540M Optimus (I am using bumblebee) Kernel 3.5.0-19-generic all updates installed! I also added ubuntu x-swat ppa for drivers. Thank you for your help!

• Why is implementing copy-paste in a touch screen based smartphone such a big deal?

  - by EpsilonVector

  I'm not entirely sure this is on-topic, but it definitely needs a programmer's understanding to be answered, and deals with general development (for a specific scenario) as opposed to a specific piece of code. In a way it also translates into "what are the challenges in doing X in a touch screen app", and similar questions have been asked here in the past. So here it is: When Apple didn't implement copy-pasting on the iPhone since version 1 I just assumed it was a UI issue- they were waiting until they figured out a good UI for it. But now the idea is out there, and Microsoft still released Windows Phone 7 without copy-pasting, promising it'll be ready in a few months. My question is: why does this takes a few months to implement? Are there some technological challenges that are unique to programming for a touch screen that I'm not familiar with?

• Power management issues on an Asus N55

  - by Andrea Borga

  I noticed that with respect to Win7 on my Asus N55 Ubuntu 12.04 tend to overheat the system. After startup the fan controller takes control of the fan, I could here it slowing down, after a few second following a login the fan increases its speed again. Though there are no processor hungry process: top shows only Xorg consuming 4%. Even with the system monitor the CPUs load look ok. Is it a power management related problem? This can cause battery life troubles in general, and electronics is never happy to be overheated. Is there a better tool to root the cause of the issue?

• Having trouble compiling UnrealScript with defaultproperties

  - by Enchanter

  Have just started scripting in Unreal Script and am following the instructions of the opening chapter of a book on the subject. I have set the development tools up as described in the book such that it is now possible to compile the scripts for UDK before adding them to a level. My issue is: the very first script the book asks you to compile is the following: class AwesomeActor extends Actor placeable; defaultproperties { Begin Object Class=SpriteComponent Name = Sprite Sprite = Texture2D'EditorResources.S_NavP' End Object Components.Add(Sprite) } And when I hit F9 in the compiler I get the following error message: Error, BEGIN OBJECT: Must specify valid name for suboject/copmponent: Begin Object class=SpriteComponent name = Sprite My question: As far as I'm aware I've copied the code from the book veribatim including capital and smaller case letters but I'm getting this error and I was wondering if anyone knew why and if so how I would fix it?

• Netbeans 7.01 in 12.04 repository, no javascript support

  - by Danielinux

  Hi I've installed Netbeans 7.0.1 from ubuntu 12.04 repository, i'm having many issues, The most important is that I cannot have help in writing javascript. Each .js file appear as a usual text file and even javascript sintax in jsp pages appear as normal text. I've already checked in tools -- options -- misc-- files and i cannot find there the .js association and the text/javascript mime-type. Another issue, really awfull, is that I cannot access CVS server if i do not run Netbeans as a root user. Someone had the same troubles i listed above? Have you some tips for solving them avoiding to install a newer version from Netbeans website? thanks in advance

• How will Qt 5.0 be packaged for Raring?

  - by George Edison

  Note: as per the FAQ, "Issues with the next version of Ubuntu" may not be asked as questions here but in my opinion, this is not an issue but merely a question asking about policy. If you feel this question is off-topic, please leave a comment explaining why or open a question on Meta.AU. How will Qt 5.0 be packaged for Ubuntu when it is released? Currently, the name of the package for installing the Qt 4.8 core libraries is: libqt4-core Will the equivalent package for the next version of Qt (5.0) be named libqt5-core? If not, what will the package be named? Will the existing Qt 4.8 libraries coexist with the Qt 5.0 equivalents for the foreseeable future or will they be removed? The Qt 5.0 beta 2 PPA contains a lot of packages - few of which seem to correspond with existing package names. If someone can provide me with a link to a policy outlining the Qt 5.0 migration plan, that would be awesome.

• High Usage of RAM by wxPython's GUI and need some advice to reduce it

  - by user67024

  I've recently developed a GUI in wxPython for windows platform. It contains a five tabs, 4 of them are just richTextCtrl boxes and the other one has controls for uploading files, buttons, textctrls, a slider etc.. As I was new to GUI development in Python, I used wxFormBuilder to generate some of the code using a good amount of sizers. So, now the problem is that the GUI starts off with a initial memory of around 40MB which is too much for such a simple application (Or so I think) . Also, when the functions handling the functions use huge lists as the program is for debugging large data logs and identifying the problems in'em implying that I can't afford memory for GUI. So, how can I reduce that start working memory size? Is it a general issue in wxPython? And currently trying use profilers but not sure if it's going to help.

• Broadcom BCM4313 wireless slow and high-latency

  - by Florin Andrei

  Ubuntu 12.10 64 bit on a Dell Latitude E6330 laptop. Wireless is pretty slow. It gets connected quick enough, but then it acts like a dialup connection. My ssh sessions over WiFi are slow and laggy. Even browsing is slow, the pages are loading like it's 1998. This does not depend on the access point, it's the same both at home and at work. Other systems work fine on these access points. I had an older Dell laptop before, different WiFi hardware, and it was much faster over the same wireless access points. Is this a known issue with this hardware? If so, any solutions?

  Hi, webmaster tools for my site displays that robots.txt unreachable and for all links in sitemap it says network unreachable. sitemap.xml unreachable. These appear in crawl stats page. I discussed with the support team of my hosting and they said... Hi, I have verified apache logs, i cannot see any issues on your website/webserver/ Possible issues. There may the routing issue from the googles server to our server. When a google bots hits goes high the IP will be automatically blacklisted by our firewall to avoid server loads & downtimes. As we donot have access to their services, We cannot able to give details of their details/logs etc. The sitemaps link shows an exclamation mark which means the file was not reachable. What could be the problem and how to solve it?

• How to workaround or diagnose a kernel panic when "safely removing" external hdd?

  - by Shawn

  I'm experiencing an issue when using the "Safely Remove" option to remove my 1TB external HDD from the Unity Launcher. Not every time, but occasionally my screen will go black and display LARGE amounts of text information (which I obviously cannot screen cap). The jist of the info displayed is that unmounting or 'safely removing' the drive causes a kernel panic. Is there a Command Line command to remove mounted drives, or at least one that would show me some sort of error output when the drive is removed? I'm trying to narrow down the cause. I could be imagining this, but it seems to happen most often when I have other programs running when I remove the drive (i.e. Firefox, Transmission). Please note that my external drive is not in use when I attempt to remove it and it is not being used either by Firefox or Transmission at these times. Any help would be appreciated.

• How can I test different TV display types for my XBLIG game?

  - by Steve Dunn

  The XBLIG submission check-list says to ensure that all important stuff critical to game-play be visible in the 'TitleSafeArea'. I've received a bug report during play-test of my game (Crazy Balloon Lite) that says parts of my scrolling 2D map are only half visible (i.e. chopped at the left of the screen). I've tested my game myself on a 47" TV and also a 19" VGA monitor, both of which look fine. The bug report says the issue occurs on a standard 20" TV. My question is: without buying different sizes of TVs, is there a way to test what my game will look like on different sized displays?

• Video capture Performance

  - by volting

  I have noticed high CPU utilization in a number of applications (except mplayer) which read from the embedded webcam on my laptop. Bizarrely CPU utilization varies proportionately to the level of illumination present. I know that that high CPU usage has nothing to do with rendering the video, as I have written a simple app using the OpenCV library to simply grab frames from the webcam, and cpu usage is still high. I think that mplayer might be using my GPU (and the other apps aren't), but since its not an issue with rendering, I dont think this explains anything. Cheese Low light --- ~12% CPU Bright Light ---- ~63% CPU Camorama Low light --- ~7% CPU Bright Light ---- ~30% CPU Opencv C++ library, (display in a single highgui window) Low light --- ~13% CPU Bright Light ---- ~40% CPU (same test on windows 7, 4-9%) Mplayer No problem, 1-2% regardless of light levels Note: If all I want't to do is capture a feed from my webcam I would use mplayer and forget about it, but I'm developing an application which uses the OpenCV to capture a video feed among other things, performance is important.

• Execute code at specific intervals, only once?

  - by Mathias Lykkegaard Lorenzen

  I am having an issue with XNA, where I want to execute some code in my Update method, but only at a given interval, and only once. I would like to avoid booleans to check if I've already called it once, if possible. My code is here: if ((gameTime.TotalGameTime.TotalMilliseconds % 500) == 0) { Caret.Visible = !Caret.Visible; } As you may have guessed, it's for a TextBox control, to animate the caret between invisible and visible states. I just have reason to believe that it is called twice or maybe even 3 times in a single update-call, which is bad, and makes it look unstable and jumpy.

• Sound plays from laptop speakers only even when headphones are connected

  - by Ankush N Nayak

  I'm using a Dell Vostro 1014 laptop with Ubuntu 11.10. From the time I had Ubuntu 9.04, sound comes from the laptop speakers only even when I plug in earphones or external speakers. Also, if an external microphone plugged in, it does not work. Dell even replaced my motherboard to check for hardware issues but the problem persists. So it is definitely not a hardware issue. The sound plays perfectly through the headphones in the pre-boot diagnostics. So I figure, this must be a problem with Ubuntu not recognizing my sound card. Please try to give a solution for this problem.

  Hi, I've just got an Dell Precision M6500 that comes with an nVidia card. Together with Kubunutu 10.10 and the proprietary nvidia driver suspend to disk or RAM does not work. It's allways ending with a running system and a locked screen (i.e. I can just enter my password and everything is as before - it's never sleeping) Can someone please help me to debug this issue? Where should I look for information? None of the log files seem to show an obvious error... Thanks, Chris
