• choppy streaming audio

  - by user88503

  I could use some help troubleshooting choppy streaming audio. The problem is jerky playback regardless of audio or video with audio. Both Chromium and Firefox have the problem, however files played directly on the machine with Rhythmbox sound just fine. I'm running 12.04 LTS on a C2D T9300. Most of the audio problems others ask about seem to be hardware related, so the following information might be relevant. sudo lshw -c multimedia *-multimedia description: Audio device product: 82801H (ICH8 Family) HD Audio Controller vendor: Intel Corporation physical id: 1b bus info: pci@0000:00:1b.0 version: 03 width: 64 bits clock: 33MHz capabilities: pm msi pciexpress bus_master cap_list configuration: driver=snd_hda_intel latency=0 resources: irq:48 memory:f8400000-f8403fff

• ManagementObjectSearcher error [migrated]

  - by Piotrek

  Some of our customers inform us that in some cases following error appears: System.Management.ManagementException: Blad dostawcy. at System.Management.ManagementException.ThrowWithExtendedInfo(ManagementStatus errorCode) at System.Management.ManagementObjectCollection.ManagementObjectEnumerator.MoveNext() The error is generated while trying to loop through a colection returned by Get() method of the System.Mamangment.ManagementObjectSearcher object. This is the code of my method: private bool PrinterExists(string printerName) { bool retVal = false; SelectQuery q = new SelectQuery("select caption from win32_printer"); using (ManagementObjectSearcher searcher = new ManagementObjectSearcher(q)) { foreach (ManagementObject printer in searcher.Get()) { if(printer["Caption"].ToString() == printerName) { retVal = true; break; } } } return retVal; } It seems that the problem appears only on Windows XP. The only workaround I know is reconstruction of WMI database. It sometimes helps, but unfortunatelly not always. Can anyone tell me what is the reason of this error and how can I fix it?

• Amazon Kindle - Whispersync implementation?

  - by Bala

  For those who are not aware of Kindle's whispersync, here is how it works (from amazon.com): "...Whispersync synchronizes the bookmarks and furthest page read among devices registered to the same account. Whispersync is on by default to ensure a seamless reading experience for a book read across multiple Kindles." Can anyone give some details on how the Whispersync feature is implemented in Kindle and in the Backend of Amazon? I am guessing this implementation involves a very simple hashmap for each user account. Each hashmap maps Books with satellite information about the book. Satellite information contains bookmarks, furthest page read, device on which it was read, etc.. Thanks!

• How do global cancel/exit commands work in bash?

  - by SecurityGate

  As I have done multiple times before, I've written bash scripts, and just general commands that go nowhere. They just blink the little command line cursor at me for infinity until I control+C the command. When I do cancel the command, what exactly is going on when I do this? Am I somehow stopping and killing the current PID I'm working on? Does it jump to a different run-level and execute something to terminate the command? On a slightly different note, I've never been able to figure out how to set up something like this in a script or program I've worked on. Since I mostly program in Ruby, can I setup something like a certain key press stops the program? Every time I've looked into doing something similar, I always end up getting hung up when it comes to user input, whether that is a loop waiting for a condition, or something like this: def Break() user_break = gets.strip end def Main() Function1() Break() Function2() Break() [...] end It seems and is incredibly bulky, and definitely isn't easily scaled up or down.

It freezes completely repeating a small sound loop from tv. cant go to terminal etc. I have a phenom II 3,40 ghz dualcore cpu , but i unlocked the other two cores so now its quadcore. On Windows i don't have any problems and i use the performance mode all the time and never breaks. I'm really dissapointed....

• Best strategy to discover a web service in a local network?

  - by Ucodia

  I am currently doing some research for a project. The setup is simple, I have a computer running a service in my home network and any device connected to that same network should be able to discover the service automatically and use it. I have no specific technology requirement whether it is on the server or client side. The client knows about the service definition. Other than that I have no idea what strategy to use, what technology to look at or whether I should go for a SOAP or a HTTP based service. I think going HTTP with REST API is the best for targeting all devices but I am opened to any suggestions. Thanks.

• Trying to re-install ubuntu 11.10on an HP Pavillion G6, screen goes black after the ubuntu logo shows.How do I get it to install normally?

  - by Josh Towers

  Installed Ubuntu 11.1 successfully without my wireless device being recognized. Used sudo apt-get update + upgrade commands to attempt to fix this. Computer crashes after upgrade and now it won't finish re-installing Ubuntu, after it shows the first purple screen with the Ubuntu logo, the screen goes black. Used the Derik's Boot Nuke CD and then attempted re-installment again, and the black screen problem remains consistent, seemingly no matter what I do. It sounds like it's installing but won't let me see anything or go anywhere. heelllppp

• ISO Live Session from an External Hard Drive?

  - by amemus

  Is it possible to use an external hard drive to start a live Ubuntu session? Is having an ISO file as the whole content of the first partition of the device enough? Thank you for reading...! EDIT upon reading the first comment to my original question: If I remember correctly, I COULD run a live session of Oneiric Ocelot somehow. It was not from a CD because I failed to burn one, so it must have been from an ISO file. Still very very confused....

• Wireless doesn't connect in Ubuntu 10.04 Lxde

  - by David

  Problem I have a Dell mini 9, and the wireless has worked without trouble in Ubuntu and Xubuntu versions 8.04 and 10.04. However, after installing lxde, the wireless doesnt connect. Network manager recognizes the local networks, and will say that it is connected, but ifconfig does not confirm the connection or the existance of a wlan0. I have another Ubuntu 10.04 notebook that works fine. My wireless device is Broadcom BCM4312 802.11b/g What I have tried I have tried to remove and install network-mananager and inxi but neither work, and sudo modprobe wl returns WARNING: All config files need .conf: /etc/modprobe.d/blacklist, it will be ignored in a future release.

• Macbook Pro late 2011 screen brightness issue

  - by buchzumlesen

  The keys to set the screen brightness work properly but everytime I reboot, the screen brightness is reverted to 100%, which is very annoying. I've already tried to add the following lines to /etc/rc.local but with no success (only the keyboard backlight stays off): #!/bin/sh -e # # rc.local # # This script is executed at the end of each multiuser runlevel. # Make sure that the script will "exit 0" on success or any other # value on error. # # In order to enable or disable this script just change the execution # bits. # # By default this script does nothing. echo '1' > /sys/devices/platform/applesmc.768/leds/smc::kbd_backlight/brightness echo '6' > /sys/class/backlight/acpi_video0/brightness rfkill block bluetooth exit 0` This worked for me when I was using Ubuntu 12.04 and also did after the upgrade to 12.10 but then after rebooting the screen brightness always reverted to 100%. Would be nice if anyone knows how to fix this. My device: Macbook Pro 13" Late 2011 Thanks in advance!

• Mouse wheel on Dell Vostro V13

  - by Scaine

  I have a Dell Vostro V13, which Canonical claim is "Certified" for Ubuntu (http://www.ubuntu.com/certification/make/Dell/laptops). So it surprises me that the synaptics trackpad isn't recognised as such and defaults to psmouse emulation. This means no multitouch, no gestures, and more importantly, no mousewheel scrolling. Because it's not loading the synaptic driver, running gpointing-device-settings doesn't help. I've found this bug : https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-input-synaptics/+bug/380126 which suggests a fix has been committed, but I can't see a way of getting this loaded on my Maverick build. I've tried backports and proposed repos in synaptic, but no joy. Any ideas?

• Synchronise graphics and logic code

  - by Skeith

  I have a procedural approach to the game loop that runs various classes. it looks like this: continue any in progress animations check for used input apply AI move things resolve events such as collisions draw it all to screen I have seen a lot of posts about how drawing should be running separately as fast as it can, possibly in another thread. My problem is that if the drawing runs as fast as it, can what happens if it tried to draw while I'm still applying the AI or resolving a collision? It could draw the wrong thing on screen. This seems to be a well established idea so there must be an explanation to this problem as I just cant get my head around it. The only solution I have is to update the screen so fast that any errors like that get refreshed before we see them but that sounds hacky. So how does this work / how would you implement it so that they are in sync but running at different speeds?

• How are hybrid VB6/.Net applications functioning in the Real World?

  - by Dabblernl

  I am maintaining a VB6 application and we are studying how to migrate to .Net We are considering doing this gradually by implementing new features in COM visible .Net classes and migrating existing functionality slowly. I found some instructive 'Hello World' examples about how to do this and it works fine with our App. But how is the real world behaviour of these hybrid applications? Are they stable, maintainable? Particular of our program is that more users on the same computer will use it by switching user accounts. EDIT: The VB6 app reads data from a USB connection and stores it in an Access database. The user can call up various views on the data. The data is cached in a hardware device, so interuptions in the reading of it are not fatal.

• Logitech Microphone (AK5370) inaudible volume

  - by Iain Lane

  I bought this microphone from Amazon last week. It's detected just fine in 12.10. I can see it in the sound preferences. The problem is that the volume is so low as to be inaudible, even when turned up to maximum in this dialog. It is working, as I can see that the meter responds to noise, but it's just too low. alsamixer's control is the same, so that doesn't help. I tried messing around in pulseaudio too, but to no avail. In lsusb it's Bus 002 Device 004: ID 0556:0001 Asahi Kasei Microsystems Co., Ltd AK5370 I/F A/D Converter.

• Assign programs permanently to different sound-outputs in Pulseaudio?

  - by Mood

  I want to assign Skype input and output to my USB-headset while the rest of my laptop uses the internal sound-card. This is an easy task with PulseAudio Volume control (pavucontrol). The only problem I have is every time a call is made I manually have to set the output and input for Skype to my USB-device . When I hang up, Skype disappears from Volume Control. It reappears again with the next call only this time the default sound-card is selected again. It shouldn’t be hard to let PulseAudio look or the USB-headset is connected when Skype audio comes is before selecting the default. The way to do it is obvious not through Volume Control.

• Can't Boot Ubuntu, video drivers or x-server problem?

  - by ZacharyH

  I was uninstalling some programs that I installed to try and get my iPod touch working with Ubuntu (I gave up on that) when ubuntu just crashed. Now after I choose ubuntu in GRUB, it gives me a screen that says "Ubuntu is running in low-graphics mode: your screen, graphics card, and input device settings could not be detected correctly. You will need to configure these yourself" It was working just fine before I started to uninstall those programs. I think that I might have uninstalled something necessary to the system. If I click OK on the screen, it gives me options to reconfigure, troubleshoot, exit to console, or restart X. But no matter what I choose I still can't boot into ubuntu - I get stuck looking at the splash screen which stalls forever. I was receiving support from one of my mate's and he was doing something with the LiveCD, and now the message doesn't pop up any more, I just get stuck at a never ending splash screen. Any help would be appreciated, thanks!

• fingerprint-gui can not recognize my upek reader (147e:1002)

  - by ymfoi

  I've got a new laptop which is Lenove's E420s. And I have encountered a big problem that I can't make the fingerprint reader work properly. I've also tried fingerprint-gui. But unfortunately, it's told that "No Device Found". Here is my screenshot: http://ge.tt/98Xg2WD/v/0 It's said that 147e:1002 is supported by fingerprint-gui on the official website. So, I'm curious about the situation. Anybody knows? P.S: I'm using gentoo, but I think this problem may not have anything to do with distribution since I compiled the source from official site.

• 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?
