• 12.10 update-manager is behaving strange?

  - by dschinn1001

  First I tried to update Kernel ( with 3.5.0-18 of your choice ) with update-manager. But update-manager crashed each time after 3 attempts when I typed my password ? Then I tried to update with terminal and apt-get as usual way. There then seems to be no update-files with a sudden after a pause --- Yes update-manager behaved strange, but it seems, that update-manager made a QUIET update ? There was nothing to see . . . I restarted my machine and new kernel is installed then.

• OKI-B2540 printer doesn't print?

  - by NCLI

  There is a driver for the OKI-B2520, and it is automatically selected when the printer is connected. From looking at various websites, it seems like the B2500, B2520, and B2540 all work perfectly fine with the OKI-B2520 driver, so I let it install that. Everything went smoothly, the printer shows up as available, and I can queue jobs without any problems, and they disappear after a few seconds. However, nothing actually comes out. There is no error message on the printer display, or from Ubuntu. This is the output from the CUPS error log: http://pastebin.com/S6ifZAup So my question is: What is wrong??

• Reliability Monitor is the Best Windows Troubleshooting Tool You Aren’t Using

  - by The Geek

  When it comes to hidden gems in Windows, nothing beats the Reliability monitor tool, hidden behind a link inside of another tool that you don’t use either. Why Microsoft doesn’t shine more light on this really useful troubleshooting tool, we’ll never know. Reliability Monitor tracks the history of your computer — any time an application crashes, hangs, or Windows gives you a blue screen of death. It also tracks other important events, like when software is installed, or Windows Updates loads a new patch. It’s an extremely useful tool. And yes, it’s in Windows 7 and 8… and even 8.1. It might be in Vista, but who uses that anymore?

• Should I continue to learn and program using ansi c or non standard? [closed]

  - by Erik

  I am a Cs Student, enthusiastic about programming. C is my first programming language that I learned. (Never been exposed to programming, data structures, algorithms before) I failed the exam because I studied on my own and didn't know how to use windows non standard libraries like conio.h. (I had to draw circles, etc using get x and get y). I told them but they just don't care. What do I do because for a beginner this is very confusing? Do I continue to study ansi c on my own, or should I study non standard c? Should I do them in parallel? *I did use the search bar but found nothing useful that could help me.

• Does the Instant Preview in Google webmaster tools takes Robot.txt in account?

  - by rockyraw

  Is that the way to go If I want to visually see what the googlebot see? I'm trying to check a folder which I have just blocked in my robots.txt. If I fetch the folder as google bot, It fetches ok, so that doesn't tell me nothing about whether the block is working I know there's a tool to check for blocking, but it is dependent on the input of the robots.txt Therefore I've tried the Instant preview, and I don't get a preview for what the bot sees ("pre-render), so I think that means that it's because the robots.txt blocks it; however - I don't see the bot tried beforehand to access my updated robots.txt, so I'm not sure how does it know that this folder is blocked? (it does preview another new folder, that is not blocked)

• Ubuntu 12.10 installation. Hit or miss Booting

  - by Robert

  I just recently downloaded and installed Ubuntu 12.10. I also completely wiped the laptop. The Ubuntu OS will only boot part of the time but never on the first time. Always, the first start up will automatically go to a purple screen and stay there. At first I waited for 45 minutes and nothing changed. Once I held down the power button to turn it off, I turned it back on to see the Asus screen followed by the grub menu. I can select "Ubuntu" and then there is a white box blinking in the top left corner. Then, it will either keep blinking or transfer to the Ubuntu loading screen(everything works fine if it gets to the loading screen). This has never happened before with prior versions of Ubuntu. Any ideas are helpful. Thanks!

• How do I get Ubuntu One on Win7 to authenticate my login?

  - by Fred jones

  I just got a new computer running Windows 7 home premium, I used to have Ubuntu One working great on my Ubuntu desktop, but now, running win7, I know my login email address and password is correct, but it still says 'Authentication failed'. Googling the problem, looks like it may be because a device was removed from my list of devices, but the only device listed is my previous Ubuntu workstation, and nothing has been removed. I also checked the windows firewall and Ubuntu One is allowed on all interfaces on incoming and outgoing, and still authentication fails. Web login to my Ubuntu One account works fine.

I see all the options but I could not click on option 2 and 3. (grey text instead of black) I already made it possible to put in to sleep mode. But I can't pause (suspend) the laptop. Anyone an idea?

• How are USB ports related to the computer power, and why would they cause my computer to freeze?

  - by BDuelz

  I have an issue with my new Toshiba laptop. Whenever I plug in an external USB device, if the laptop is not plugged in to the wall, the laptop freezes. However, nothing happens if the laptop is plugged in to the wall. When I say the laptop freezes, I mean it really freezes. The only way to recover is to hard reboot. My question is, what could be causing this? Could it be the extra power drain from the sub devices that causes this (even the simplest flash drives cause a freeze)? Please help me out, it's very annoying. Thanks

• VirtualBox: Start Firefox in Ubuntu via a Windows script?

  - by SpaceRook

  I am using VirtualBox to run Ubuntu 12.04 as a guest in a Windows 7 host. I would like execute a command in Windows that will launch Ubuntu's Firefox. I tried VirtualBox's VBoxManage guestcontrol function. The command seems to do something, but nothing seems to happen in Ubuntu: C:\VirtualBox>VBoxManage.exe guestcontrol MyVirtualMachineUbuntu exec --image "/usr/bin/firefox" --username bob --password password --wait-stdout --verbose Waiting for guest to start process ... Waiting for process to exit ... Exit code=1 (Status=500 [successfully terminated]) The /usr/bin/firefox command works when I run it in Ubuntu. Also, with guestcontrol, I can successfully call /bin/ls. But I can't actually get a major program like Firefox to run. Any ideas? Thanks.

• Problems after installing Ubuntu LiveUSB on my 2nd HD

  - by user113106

  I decided to create a Ubuntu USB installer using the Universal USB Installer, selecting a Ubuntu 12.10 ISO. I selected my D: drive, my NON-windows7 carrying drive as install. After this I Re-booted my system and my PC began to Run the Ubuntu Boot-startscreen every time I power up the machine, giving errors like this: Root=Unknown I used my girlfriend's laptop to create, on the exact same way, a real! USB Ubuntu installer. Booting from that USB, picking the option Run Ubuntu from this USB I get the following error: http://postimage.org/image/63qkv98c1/ Let's try installing it from that USB to a Hard-Disk: http://postimage.org/image/usqbwymfx/ As I said: I do not have the Option to pick my Boot-section, at this very moment I can only access to the Ubuntu installation and nothing else. I've read about 90% of other Questions that could've been related, but I could not find a solution. BTW I'm running a Acer Aspire 2Quadcore 4gb DDR 2 Ati Radeon HD, 64bit and I've set my Bios OS-usage from Windows to "Others"

• How to write loosely coupled classes in node.js

  - by lortabac

  I am trying to understand how to design node.js applications, but it seems there is something I can't grasp about asynchronous programming. Let's say my application needs to access a database. In a synchronous environment I would implement a data access class with a read() method, returning an associative array. In node.js, because code is executed asynchronously, this method can't return a value, so, after execution, it will have to "do" something as a side effect. It will then contain at least 1 line of extraneous code which has nothing to do with data access. Multiply this for all methods and all classes and you will very soon have an unmanageable "code soup". What is the proper way to handle this problem? Am I approaching it the wrong way?

• StreamInsight will not push feature releases through Microsoft Update going forward

  - by Roman Schindlauer

  Until now, we've released StreamInsight through the Microsoft Download Center, and also released it out through Microsoft Update. Going forward, we will only release new StreamInsight versions through the Microsoft Download Center and only use MU to release service packs and security fixes (should any be needed). As a result of this decision, we are pulling off the recent StreamInsight 2.1 release from MU; this release is still available in Download Center. Don’t worry: there’s nothing wrong with the versions we’ve shipped in MU, we’ve just adjusted how we use MU. There is no action necessary from our customers as a result of this change, and we are not rolling back any changes to your current installation, so if you have installed StreamInsight 2.1 recently through the Microsoft Update, they will still work fine. Regards, The StreamInsight Team

• What is the correct way to implement hit detection with non-rectangular sprites?

  - by hogni89

  What is the correct way to implement hit or touch detection for non-rectangular sprites in Cocos2d? I am working on a jigsaw puzzle, so our sprites have some strange forms (jigsaw puzzle bricks). As of now, we have implemented the "detection" this way: - (void)selectSpriteForTouch:(CGPoint)touchLocation { CCSprite * newSprite = nil; // Loop array of sprites for (CCSprite *sprite in movableSprites) { // Check if sprite is hit. // TODO: Swap if with something better. if (CGRectContainsPoint(sprite.boundingBox, touchLocation)) { newSprite = sprite; break; } } if (newSprite != selSprite) { // Move along, nothing to see here // Not the problem } } - (BOOL)ccTouchBegan:(UITouch *)touch withEvent:(UIEvent *)event { CGPoint touchLocation = [self convertTouchToNodeSpace:touch]; [self selectSpriteForTouch:touchLocation]; return TRUE; } I know that the problem is in the keyword "sprite.boundingBox". Is there a better way of implementing this, or is it a limitation when using sprites based on .png's? If so, how should I proceed?

• How to enable a symlink in this case

  - by Bragboy

  I cannot categorize this question under ubuntu since it has nothing to do with it. But I know people here can definitely answer this. I login to one of my deployment boxes using SSH (no ubuntu here). I am working in a tool called TeamCity which uses a folder called ".BuildServer" under home directory of the user. This folder may grow in size as the application runs but the current user is only given a limited amount of space. But the good thing this I got a folder access outside /home/deploy (deploy being the user here) folder. I now want to link this .BuildServer inside the /home/deploy directory to the other folder where I got permission for (meaning all the files should be re-routed to that directory) Hope my question was clear, please help.

• How to deal with readers requesting free advice / support on my blog? [closed]

  - by russau

  I have a handful of popular articles on my blog (nothing huge), and they attract the occasional developer who wants help implementing some code grabbed from my blog. Now I'm getting people who haven't made any attempt to learn the code, email me their code, and expect me to trace it through for them. I'm sure anyone with a half-popular blog gets similar requests. What's the best way to deal with this scenario? I want to put together a boilerplate response including these points: How far have you gone with this on your own? (is it any benefit for anyone if I say they are being imposing) I'm happy to help with any problems you find in my code Point them to other forms of help such as stackoverflow, diagnostic tools relevant to the topic.

• access to site owner not working

  - by Daveo

  I made a website it works for everyone except for the site owner, who cannot access the site. He gets a server could not be found error. I went to his house and the issue occurs for all of his devices (PC, laptop, iPhone using WiFi) when I turn WiFi off the iPhone it works. So I thought it was a problem on his router so I reset is router to default factory settings but it still does not work, I have flushed his DNS cache and his browser cache. But nothing seems to help. He cannot even PING the server using the domain name. However when he uses the IP address he can see the site fine. I looked in cpanel for an blocked IP addresses but cannot see anything. What could be stopping just him from accessing the site via domainname and not the IP address? Site details are: PHP, osCommerce it is hosted by site5 on my reseller account.

• Not detecting HDD after installing Ubuntu 12.04!

  - by Arthur

  After installing Ubuntu 12.04, which I'm using right now and it works great, my extra hard drive was detected the first time I turned on my computer but then it does not show anymore on my Home Folder, when I run the Disk Utility says that has a few errors but when I try to fix it, says that hard drive is busy and cannot do anything else. I've unmounted it and mounted again but nothing happens. Do you know what can be going on? Cause the first time that I was able to see my hard drive it had all the files I have, but I don't know if deleting the partition will format the whole hard drive or just the ubuntu files. THANKS in advance! BY THE WAY, I'm new to Ubuntu... :S

• What IRC client(s) would allow me to filter out log messages?

  - by Aras

  I have been using Empathy and more recently Pidgin as my IRC client. But there is one feature missing from both of these clients that keeps bothering me. I want to be able to see only what people are actually talking about in each channel. I often like to leave IRC channels open and go back to them and read the messages for the last few hours or days. I saw that IRC clients have been discussed in this post and a few others, but I have not found what I am looking for yet. Here is what I want to see in my IRC client: what actual people say Here is what I do not want to see message about people entering the room people leaving room people changing their status messages or what they are known as people sneezing people's cats sneezing Anyway, you get the picture. What IRC clients are available for Ubuntu that would allow me to configure what I see so that I can see what people are talking about -- and nothing else?
