  • Can't login to Ubuntu One

    - by Gabriel
    I uninstalled Ubuntu One about two months ago and now I re-installed it. I can still login with my account through the site (Ubuntu One) but the client keeps telling me "The authentication failed". If I try to use the Recover password option it also fails with telling me that my email address is not recognized (while I can use it with zero issues through the site) If I attempt to create a new account from the client, it also fails to load the captcha every time. Something is clearly broken here but I can't figure out what it is. Any ideas?

  • Is avoiding the private access specifier in PHP justified?

    - by Tifa
    I come from a Java background and I have been working with PHP for almost a year now. I have worked with WordPress, Zend and currently I'm using CakePHP. I was going through Cake's lib and I couldn't help notice that Cake goes a long way avoiding the "private" access specifier. Cake says Try to avoid private methods or variables, though, in favor of protected ones. The latter can be accessed or modified by subclasses, whereas private ones prevent extension or re-use. in this tutorial. Why does Cake overly shun the "private" access specifier while good OO design encourages its use i.e to apply the most restrictive visibility for a class member that is not intended to be part of its exported API? I'm willing to believe that "private" functions are difficult test, but is rest of the convention justified outside Cake? or perhaps it's just a Cake convention of OO design geared towards extensibility at the expense of being a stickler for stringent (or traditional?) OO design?

  • memory and time intensive php task

    - by Goddard
    Sorry if this question has been asked before, but I couldn't find anything usable. I'm working on a project for a client and currently I have to loop through the users table which is about 3000 records and still growing. I have to do some calculations on a nightly basis which I am going to be using cron/php. The calculations script uses about 3.5mb of memory and takes about 1 second to run. When loading individual users my current php setup handles this fine, but if I try and loop through the user list my php script execution time runs out. I've read after doing some searching that I can make the page reload itself after each user calculation and just keep my previous place in the loop and this sounds like a good idea, but I wanted to hear some opinions from others that have handled similar situations and how you handled these types of tasks. Thanks.

  • How do I get to the maintenace shell?

    - by Narida
    I'm asking this because initially, my problem was this (power failure during installation, so I typed the following instructions in the maintenance shell: sudo mount -o remount,rw / sudo dpkg --configure a sudo mount -o remount,ro / sudo sync sudo reboot The first three lines worked, afterwards, my computer (a Dell Inspiron 530) got stalled for several hours, so I unplugged it. When I turned it on, the log in screen appeared, and after I try to write my password, it leads me back to the log screen. I must note that when I typed the first three lines during the maintenance shell mode, it said that the errors which were encountered during processing were: initscripts bluez gnome-bluetooth So, what do I have to do in order to get back to the maintenance shell so I can type code again? And, what code do I have to write in order to restore my computer? Thank you for your attention.

  • Android Loading Screen: How do I go about using a stack to load elements, and the option of incrementing the size counter?

    - by tom_mai78101
    I have some problems with figuring out what value I should put in the function: int value_needed_to_figure_out = X; ProgressBar.incrementProgressBy(value_needed_to_figure_out); I've been researching about loading screens and how to use them. Some examples I've seen have implemented Thread.sleep() in a Handler.post(new Runnable()) function. To me, I got most of that concept of using the Handler to update the ProgressBar, while pretending to do some heavy crunching work. So, I kept looking. I have read this thread here: How do I load chunks of data from an assest manager during a loading screen? It said that I can try using a stack it needs to load, and adding a size counter as I add elements to the stack. What does it mean? This is the part where I'm totally stumped. If anyone would provide some hints, I'll gladly appreciate it. Thanks in advance.

  • Upload Recordings Of The Problem To Your SR

    - by Irina
    Do you find yourself trying several times to explain a problem in a Service Request? Does the support engineer ask more than once for clarification? If so, you might be interested in DITO -- Demo It To Oracle. DITO uses CamStudio (free download!) to record the exact nature of the problem, and upload the output to your SR. The following articles provide more details: Working with Support - MOSSOS (Doc ID 1265130.1) "Demo It To Oracle" (DITO) - CamStudio Help ( Doc ID 11.1) Why take up valuable time first explaining the problem, then trying to get a web conference setup to show exactly what is going on? The next time you file an SR, try including a recording showing exactly which application is failing, where it is failing, and what it looks like when it fails.

  • Steps to rebuild gspca_kinect driver module?

    - by Bobby Ray
    I recently purchased a Kinect for Windows and quickly discovered that the camera drivers included in linux kernel 3.0+ aren't compatible with the Kinect for Windows hardware revision. After looking at the source code it seems like a tiny modification is all that is required for compatibility, so I've been trying to recompile the driver - to no avail. I've been referring to this article and this one as well, though they are a bit outdated. When I try to compile the module, I get an error because the header file "gspca.h" can't be found in the include path. I located the missing header in my filesystem, but the file itself is empty. I've also tried downloading the kernel source (3.2.0-24-generic), which allowed me to compile the module, but when I load the module I get an error. -1 Unknown symbol in module Is there a standard way to go about this without first building the kernel? Will building the kernel ensure that I can build the module? Thanks

  • Is there any way to prevent Googlebar from breaking Friendly 404s

    - by TecBrat
    This might be considered a continuation of this question. If I output HTML after my 404 header, It displays properly in IE and FF unless the user has Google bar instaled. If I try header('HTTP/1.x 404 Not Found'); header("Location: http://www.example.com/?content=404_error"); die(); then I'm getting 302 from the redirect. It seems to overrule the 404 Supposedly if your output is larger than 512 bytes, the toolbar isn't supposed to override the page, but It seems to do it anyway. I found a setting in Google's Toolbar that said "Provide suggestions on navigation errors". Turning that off provides me with the behaviour I want my visitors to experience. Does anyone know if Google provides a way for a developer to over-ride that setting for all visitors?

  • Why do recruiters contact you instead of the companies themselves? [closed]

    - by Chloe
    When posting my resume, I get hounded by recruiters who try to sell me on a job. Why don't the actual company HR employees contact me directly? My information is available for them to find. Wouldn't they save money by bypassing the recruiter fees? Out of the hundreds of recruiter phone calls, only 2 actual companies contacted me directly (and 2-3 other non-company individuals). Should the HR employees be let go if they are so irrelevant? (The careers exchange doesn't allow posting questions.)

  • Android - Force Close - Null Pointer on Canvas?

    - by user22241
    Please bear with me. I have a very odd problem. Basically, my app so far, has 3 activities (a main splash screen, an 'options/menu' screen and the main app). If I follow the very specific steps oulined below, I get a 'null pointer exception' in the 2nd activity) and the app force closes...... Here are the steps: Start the app (a game based on Surfaceview), tap through to the third activity so the game is running, then hit the home key so the game is paused and put to the background, the activity/app is ended through DDMS in the SDK then restarted on the device (all OK so far), now if I hit the back key on the device twice in quick succession, it happens. All other sequence of events is fine, even to the point of pressing the back key, waiting for the previous activity to show, then hitting back again - all OK. Only when the back key is pressed twice in quick succession following all the above steps does the problem occur. I'm assuming that the canvas isn't ready as it's showing as 'null' when this happens, but I'm not sure why this is happening as surely it's happening when I'm trying to go back to activity 1, but the logcat shows the error in activity 2. if I stop the activity running my 'doDraw' method (which referenced the canvas), then all is OK - so I can safely assume it is the canvas causing the problem. Also, if I skip my first activity (which is a very basic full-screen button which just displays a splashscreen and waits for the user to tap the screen), and make my 2nd activity the launch activity, again, it is OK. this is the part of the code that I think is probably relevant: @Override public void surfaceChanged(SurfaceHolder arg0, int arg1, int arg2, int arg3) { vheight = this.getHeight(); vwidth = this.getWidth(); } @Override public void surfaceCreated(SurfaceHolder holder) { vheight = this.getHeight(); vwidth = this.getWidth(); this.viewWidth = vwidth; this.viewHeight = vheight; if (runthread==false){ if (preThread.getState()==Thread.State.TERMINATED){ preThread = new OptionsThread(thisholder, thiscontext, thishandler); } preThread.setRunning(true); preThread.start();} } @Override public void surfaceDestroyed(SurfaceHolder holder) { preThread.setRunning(false); //Stop the loop boolean retry = true; //Stop the thread while (retry) { try { preThread.join(); retry = false; } catch (InterruptedException e) { } } Thank you all for any help you can offer

  • Intercepting the Unity logout

    - by qbi
    I want to copy some data from another machine to a local computer on a regular basis. At the moment I'm researching different solutions and try to find the one which fits best. Basically I want to open a network connection (or use an existing one), make a VPN connection and start a rsync process. This should be done on every logout of my desktop session or on shutdown. One possible solution might be to somehow intercept the Unity shutdown and execute a script. So is there a possibility to execute a script on GNOME/Unity shutdown? I'm aware that you can do it on system shutdown. How can I do this?

  • GRUB install error

    - by Rohit
    Whenever I try to install Ubuntu, I get a fatal error that reads: 'Executing'grub-install /dev/sda' failed. This is a fatal error.' Its the same as this, but my graphics appear to be running fine. Also, I'm a complete novice at this and really need simple instructions to understand what I'm doing. I've tried booting from a LiveCD and a USB stick. I don't want to dual boot it because its an old computer that I erased XP and plan on only using Linux on it. When I used a USB stick and set the persistent file storage high, I was able to run it, but only as long as the flash drive was plugged in.

  • My Brother printer doesn't accept quality settings anymore - what can I do?

    - by rearlight
    I have a Brother MFC-465CN network printer. It uses the brother-cups-wrapper-bh7 and brother-lpr-drivers-bh7drivers. Now, when I print (which works perfectly fine) I try to print in "fast normal" settings to save some ink. I use LibreOffice and Ubuntus default PDF-viewer to print and set the settings in the print dialog manually. "Fast normal" is the default printing setting (in the Ubuntu GUI printing config). But the printer always prints in "normal" or even "fine" quality settings which takes forever and uses much more ink. So, what can I do about that? Thanks for your help in advance!

  • File manager (Nautilus) hangs or is ultra slow when listing contents of ssh/sftp server

    - by NahsiN
    I used to use File -- Connect to server to connect to my remote ssh a lot before 12.04/11.10. But now in a fresh install of 12.04, whenever I try to access the remote files, nautilus either always hangs or is ultra slow (5 mins) in listing the directory contents. Most of the time I have to force quit or xkill. Mounting using SSHFS works fine. The ssh server is fast and it works fine via putty, mc (using fish) and normal terminal. I also installed nautilus in Lubuntu 12.04 (virtualbox) and to my surprise, browsing is fast and smooth. Both versions of nautilus are at 3.4.2 thus I am led to believe the problem might be lying somewhere in Ubuntu 12.04. But I am clueless. All suggestions welcome. I really need to solve this problem.

  • Moms on Mobile: Are They Way Ahead of You?

    - by Mike Stiles
    You may have no idea how much and how fast moms are embracing mobile. Of all the demographics that can be targeted by marketers, moms have always been at or near the top of the list. And why not? They’re running households, they’re all over town, they’re making buying decisions, and they’re influencing family and friends. They, out of necessity, become masters of efficiency and time management. So when a technology tool, like mobile, comes along that assists with that efficiency and time management, we would obviously expect them to take advantage of it. So if it’s obvious, why are so many big, sophisticated brands left choking on the dust of moms who have zoomed past them in the adoption of mobile, and social on mobile? Let’s break down some hard truths as presented by a Mojiava report: -Moms spend 6.1 hours per day on average on their smartphones – more than magazines, TV or radio. -46% took action after seeing a mobile ad. -51% self-identify as “addicted” to their smartphone. -Households with an income of $25K-$50K have about the same mobile penetration among moms as those with incomes of $50K-$75K. So mobile is regarded as a necessity for middle-class moms. -Even moms without smartphones spend 2.5 hours on average per day on some connected mobile device. -Of moms with such devices, 9.8% have an iPad, 9.5% a Kindle and 5.7% an iPod Touch. -Of tablet-owning moms, 97% bought something using their tablet in the last month. -31% spend over 10 hours per week on their tablet, but less than 2 hours per week on their PCs. -62% of connected moms use shopping apps. -46% want to get info on their mobile while in a store. -Half of connected moms use social on their mobile. And they’re engaged. 81% are brand fans, 86% post updates, and 84% comment. If women and moms are one of your primary targets and you find yourself with no strong social channels where content is driving engagement and relationship-building, with sites not optimized for mobile, or with no tablet or smartphone apps, you have been solidly left behind by your customers and prospects. And their adoption of mobile and social on mobile is only exponentially speeding up, not slowing down. How much sense does it make when your customer is ready to act on your mobile ad, wants to user your iPad app to buy something from you, wants to be your fan on Facebook, wants to get messages and deals from you while they’re in your store…but you’re completely absent? I’ll help you cheat on the test by giving you the answer…no sense at all. Catch up to momma.

  • Unable to mount location, Can't mount file

    - by user116008
    I'm a new user to Ubuntu and I have a problem: I had Windows XP in my computer and I had two partitions: C (for system data) and D(for my personal stuff), then, during the Ubuntu installation I chose the Advanced Settings and formated C partition and left D partition intact, went back and chose Install Ubuntu and replace Windows and it installed fine. The problem is that now I open Nautilus and go to Computer, in there it shows my D partition, 640 Hard Disk, but when I try to mount it displays me a message: "Unable to mount location. Can't mount file". I ask you to explain me step-by-step what I need to do because I'm not an advanced user.

  • Windows 8 and "Formerly known as Metro" apps, an experience with PDF app

    - by Kevin Shyr
    I'm slowing and surely getting used to Windows 8.  It is no doubt a slow process since I still run daily on an XP machine, a Vista machine, and 3 windows 7 box. A new quirk I found regarding Windows 8.  I never thought it was important to learn how to close a "formerly known as Metro" app (what do we call those these days?).  Then I attached a portable drive to my laptop and opened up a PDF file, and I couldn't safely remove the hard drive afterwards because I did not know how to close the PDF reader app. I have since learned that if you want to close an app, you can try Alt + F4 mouse over the top left corner and swipe down, right-click to close you app Windows Key + TAB, right-click to close the app All these make me wonder, how do you do this in a phone or tablet?

  • No sound, even though devices appear OK

    - by Felix
    I have a weird problem. Sound used to work until a couple of days ago, but now the builtin speakers in my ThinkPad W520 have stopped working. This happened after either: An update Using the headphone jack in my laptop dock (I had used the jack in the actual laptop before without issues) As I was saying, the speakers do not work at all. Sometimes I get a clicking sound from the laptop, which I assume is the system beep. This does not happen consistently. If I plug headphones in the laptop, I do get sound in them. I have tried playing with all the possible settings both in gnome and using alsamixer. Some screens: What could I try next?

  • How do I install Ubuntu to a USB key?

    - by badp
    If you are hurrying to reply, System ? Administration ? StartUp Disk Creator -- no, that's not what I'm talking about. I want to try Ubuntu 11.04's Unity without touching my existing Ubuntu install. To do this, I need to install the nVidia drivers first (sigh). To do this, I need changes to persist a reboot. To do this, I need to really install Ubuntu on a USB key. How do you do that? What I tried I tried to make a USB key from Testdrive, then boot from it, then choose "Install Ubuntu." The installer refused to install to the installation media itself. I tried, from my installed copy of Ubuntu: sudo kvm /dev/sdb --cdrom .cache/testdrive/iso/ubuntu_natty-desktop-i386.iso ...but the installer didn't detect the disk properly.

  • Problems with the colors on my screen. How can I check if it's a hardware problem?

    - by Ingo Gerth
    On my EEE PC netbook some colors are not displayed properly. Specifically, dark gradients such as in the window title do not look very smooth, but rather look like a sequence of a couple of different colors. This is especially visible when opening a menu, for example the "File" menu in Firefox. As you know this one is black, and it looks terrible on my screen. It is not just black, but the colors look really graded and far from a smooth gradient or anything. Now I am wondering: Is this a hardware or software issue? And how can I check this? If it should be a fixable problem I think it would be worth another question. Note that I am using Natty. If my problem description is not good enough I can try to take a photo.

  • Rhythmbox iPod Issues?

    - by Jonathan Jones
    basically, when I try and drag a song from my library to any one of my iPods (Classic (2.0.4 Mac), Touch (3.1.2. (7D11)) and Shuffle), nothing happens. It would appear that everything went ok, but... when I go to the iPod's library, the song is not there. When trying to transfer the file, there is no error etc. to suggest something that went wrong, and so I can't file a bug report on Launchpad etc. Does anyone know what could be wrong? Cheers guys! EDIT: I forgot to add that I'm running a 64-bit install of Ubuntu 12.04LTS and that Amarok and gtkpod don't even recognise that any devices are plugged in. Thanks.
