  • How to create a controllable flip effect (flip as far (and fast) as you drag) of an UIView

    - by allisone
    I have a card (a flashcard you could say) What I can do: On fingersweeping over the flashcard the card gets turned. It's happening by detecting touchesBegan and touchesMoved and then I do stuff like [UIView beginAnimations:@"View Flip" context:nil]; [UIView setAnimationDuration:0.5]; [UIView setAnimationCurve:UIViewAnimationCurveEaseInOut]; if (left) { [UIView setAnimationTransition: UIViewAnimationTransitionFlipFromLeft forView:self.flashCardView cache:YES]; }else{ [UIView setAnimationTransition: UIViewAnimationTransitionFlipFromRight forView:self.flashCardView cache:YES]; } What I can't do (but want to): I want to somehow drag the flip. Imagine this, you have a flashcard and you think you know the answer, you start flipping the card around because you want to see if you are correct, but then... no stop... you hesitate, turn back the card to the way it was, rethink, get the real answer and then finally flip to see that you were right to hesitate. Now I only have: once you start flipping, you can't stop it.

  • Why isn't the "this." command needed in this constructor? (java)

    - by David
    I'm reading a book about java. It just got to explaining how you create a class called "deck" which contains an array of cards as its instance variable(s). Here is the code snippit: class Deck { Card[] cards; public Deck (int n) { cards = new Card[n]; } } why isn't the this. command used? for example why isn't the code this: class Deck { Card[[] cards; public Deck (int n) { this.cards = new Card[n]; } }

  • Why are my USB 2.0 devices hanging Windows XP?

    - by BenAlabaster
    Background on the machine I'm having a problem with: The machine was inherited and appears to be circa 2003 (there's a date stamp on the power supply which leads me to this conclusion). I've got it set up as a Skype terminal for my 2 year old to keep in touch with her grandparents and other members of the family - which everyone loves. It has a generic ATX motherboard with no identifying markings other than one stamp that says "Rev.B". CPU-Z identifies the motherboard model as VT8601 but doesn't provide me with any manufacturer name. On board it has 1 x 10/100 LAN, 2 x USB 1.0, VGA, PS/2 for KB and mouse, parallel port, 2 x serial ports, 2 x IDE, 1 x floppy, 2 x SDRAM slots, 1 x CPU housing that is seating a 1.3GHz Intel Celeron CPU, 3 x PCI, 1 x AGP - although you can only use 2 of the PCI slots if you use the AGP slot due to the physical layout of the board. It's got 768Mb PC133 SDRAM - 1 x 512Mb & 1 x 256Mb installed as well as a D-LINK WDA-2320 54G Wi-Fi network card and a generic USB 2.0 expansion board containing 3 x external + 1 x internal USB connectors - it has a NEC uPD720102 chipset. It has a DVD+/-RW running as master on IDE1 and a 1.44Mb 3.5" floppy drive connected to the floppy connector. It has an 80Gb Western Digital hard drive running as master on IDE0. All this is sitting in a slimline case. I don't know the wattage of the PSU, but can post this later if this proves to be helpful. The motherboard is running a version of Award BIOS for which I don't have the version number to hand but can again post this later if it would be helpful. The hard disk is freshly formatted and built with Windows XP Professional/Service Pack 3 and is up to date with all current patches. In addition to Windows XP, the only other software it's running is Skype 4.1 (4.2 hangs the whole machine as soon as it starts up, requiring a hard boot to recover). It's got a Daytek MV150 15" touch screen hooked up to the on board VGA and COM1 sockets with the most current drivers from the Daytek website and the most current version of ELO-Touchsystems drivers for the touch component. The webcam is a Logitech Webcam C200 with the latest drivers from the Logitech website. The problem: If I hook any devices to the USB 2.0 sockets, it hangs the whole machine and I have to hard boot it to get it back up. If I have any devices attached to the USB 2.0 sockets when I boot up, it hangs before Windows gets to the login prompt and I have to hard boot it to recover. Workarounds found: I can plug the same devices into the on board USB 1.0 sockets and everything works fine, albeit at reduced performance. I've tried 3 different kinds of USB thumb drives, 3 different makes/models of webcams and my iPhone all with the same effect. They're recognized and don't hang the machine when I hook them to the USB 1.0 but if I hook them to the USB 2.0 ports, the machine hangs within a couple of seconds of recognizing the devices were connected. Attempted solutions: I've seen suggestions that this could be a power problem - that the PSU just doesn't have the wattage to drive these ports. While I'm doubtful this is the problem [after all the motherboard has the same standard connector regardless of the PSU wattage], I tried disabling all the on board devices that I'm not using - on board LAN, the second COM port, the AGP connector etc. through the BIOS in what I'm sure is a futile attempt to reduce the power consumption... I also modified the ACPI and power management settings. It didn't have any noticeable affect, although it didn't do any harm either. Could the wattage of the PSU really cause this problem? If it can, is there anything I need to be aware of when replacing it or do I just need to make sure it's got a higher wattage than the current one? My interpretation was that the wattage only affected the number of drives you could hook up to the power connectors, is that right? I've installed the USB card in another machine and it works without issue, so it's not a problem with the USB card itself, and Windows says the card is installed and working correctly... right up until I connect a device to it. The only thing I haven't done which I only just thought of while writing this essay is trying the USB 2.0 card in a different PCI slot, or re-ordering the wi-fi and USB cards in the slots... although I'm not sure if this will make any difference - does anyone have any experience that would suggest this might work? Other thoughts/questions: Perhaps this is an incompatibility between the USB 2.0 card and the BIOS, would re-flashing the BIOS with a newer version help? Do I need to be able to identify the manufacturer of the motherboard in order to be able to find a BIOS edition specific for this motherboard or will any version of Award BIOS function in its place? Question: Does anyone have any ideas that could help me get my USB 2.0 devices hooked up to this machine? Edit: Updated the USB 2.0 info with reference to actual card - http://www.xpcgear.com/lpnec4u.html

  • Passing Data thru NSTimer UserInfo

    - by zorro2b
    I a trying to pass data thru userInfo for an NSTimer call. What is the best way to do this? I am trying to use an NSDictionary, this is simple enough when I have objective c objects, but what about other data? I want to do something like this, which doesn't work as is: - (void) play:(SystemSoundID)sound target:(id)target callbackSelector:(SEL)selector { NSLog(@"pause ipod"); [iPodController pause]; theSound = sound; NSMutableDictionary *cb = [[NSMutableDictionary alloc] init]; [cb setObject:(id)&sound forKey:@"sound"]; [cb setObject:target forKey:@"target"]; [cb setObject:(id)&selector forKey:@"selector"]; [NSTimer scheduledTimerWithTimeInterval:0 target:self selector: @selector(notifyPause1:) userInfo:(id)cb repeats:NO]; }

  • How do I return an array from a method?

    - by dwwilson66
    I'm trying to create a deck of cards for my homework. Code is posted below. I need to create four sets of cards (the four suits) and am create a multidimensional array. When I print the results instead of trying to pass the array, I can see that the data in the array is as expected. However, when I try to pass the array card, I get an error cannot find symbol. I've got this modeled after texbook and Java tutorial examples, and I need some help figuring out what I'm missing. I've over-documented to give an idea of how I'm thinking this SHOULD work...please let me know where I've gone horribly wrong in my understanding. import java.util.*; import java.lang.*; // public class CardGame { public static int[][] main(String[] args) { int[][] startDeck = deckOfCards(); /* cast new deck as int[][], calling method deckOfCards System.out.println(" /// from array: " + Arrays.deepToString(startDeck)); } public static int[][] deckOfCards() /* method to return a multi-dimensional array */ { int rank; int suit; for(rank=1;rank<14;rank++) /* cards 1 - 13 .... */ { for(suit=1;suit<5;suit++) /* suits 1 - 4 .... */ { int[][] card = new int[][] /* define a new card... */ { {rank,suit} /* with rank/suit from for... loops */ }; System.out.println(" /// from array: " + Arrays.deepToString(card)); } } return card; /* Error: cannot find symbol } }

  • Componentizing complex functionality in an MVC web app

    - by NXT
    Hi Everyone, This is question about MVC web-app architecture, and how it can be extended to handle componentizing moderately complex units of functionality. I have an MVC style web-app with a customer facing credit card charge page. I've been asked to allow the admins to enter credit card payments as well, for times when credit cards are taken over the phone. The customer facing credit card charge section of the website is currently it's own controller, with approximately 3 pages and a login. That controller is responsible for: Customer login credential authentication Credit card data collection Calling a library to do the actual charge. reporting the results to the user. I would like to extract the card data collection pages into a component of some kind so that I can easily reuse the code on the admin side of the app. Right now my components are limited to single "view" pages with PHP style embedded Perl code. This is a simple, custom MVC framework written in Perl. Right now, controllers are called directly from the framework to service web requests. My idea is to allow controllers to be called from other controllers, so that I can componentize more complex functionality. For simplicity I think I prefer composition over inheritance, even though it will require writing a bunch of pass-through methods (actions). Being Perl, I could in theory do multiple inheritance. I'm wondering if anyone with experience in other MVC web frameworks can comment on how this sort of thing is usually done. Thank you.

  • Using finch first time. How to play mp3,ogg or other formats (wav files to big) ?

    - by Allisone
    My *.wav's work as expected. But wav files are to big, so I want to play *.mp3 or *.ogg but it doesn't work. I use this lines of code found in the finch Demo project engine = [[Finch alloc] init]; sitar = [[Sound alloc] initWithFile:RSRC(@"sitar.wav")]; [sitar play]; So I only change sitar.wav into my .mp3 filename. Note 1: It mustn't be mp3 or ogg, any file format not as huge as wav should be ok, but which ? Note 2: I didn't know how to use sound, so I searched and found finch here at stackoverflow. It looks easy, so I would like to use that, but if you know some other easy way to play that sound files (ambient + effects sound with compressed codec) I would also switch to that other technique.

  • UI design for screen which has number of data entry textFields.

    - by shilpa
    Hi all, my app is an e-commerce application. During the checkout process, I have "recipient" and "credit card" screens. In the recipient screen, there are number of fields for address entry, which makes it very clumsy. Same in the case of the credit card screen, where the user is asked to enter their credit card info and billing address. Can anyone suggest how to design these two pages?

  • jquery delay a link from being followed

    - by Dan Sinker
    I have a short css-based animation that I want to play out before a link is followed (a card that swooped in on page load swoops out after click). Currently, however, the page called loads too quickly. I want to be able to briefly delay the href from being followed. Here's what I've got: $(document).ready(function() { $("#card").css("top","0px"); $(".clickit").click(function() { $("#card").css("top","-500"); }); }); The first line swoops the card in on page load. After that is the click call that modifies the CSS, but like I said there needs to be some kind of delay in there because the page loads immediately, instead of after the animation. The CSS that is modified looks like this: #card { width: 400px; height: 500px; position: relative; top: -500px; -webkit-transition:all .5s; } (yes, I know this is webkit-only right now) This is a problem very similar to this question from 2008, but I know jQuery has been updated significantly since then, so I wanted to see if there was a more modern solution. Thank you!

  • audio error in vmware running mac os x

    - by PenguinSource
    simple synchronous loading of an audio file (.mp3) in a cocos2d app makes my vmware disconnect the sound. the error is display bottom right, saying 'error in creating sound stream; sound is disconnected' i read that it might be cause of my vmware's version (mine is 8) but I'm looking for a fix, not to downgrade to another version. before i get that error, the sound on the system works just fine (youtube, etc) the exact code im calling is.. [CDSoundEngine setMixerSampleRate: CD_SAMPLE_RATE_MID]; [[CDAudioManager sharedManager] setResignBehavior: kAMRBStopPlay autoHandle:Yes]; soundEngine = [SimpleAudioEngine sharedEngine]; [soundEngine preloadBackgroundMusic:@"somemp3.mp3"]; [soundEngine playBackgroundMusic:@"somemp3.mp3"]; maybe the bit rate is too high .. ? thanks

  • How can I use TDD to solve a puzzle with an unknown answer?

    - by matthewsteele
    Recently I wrote a Ruby program to determine solutions to a "Scramble Squares" tile puzzle: I used TDD to implement most of it, leading to tests that looked like this: it "has top, bottom, left, right" do c = Cards.new card = c.cards[0] card.top.should == :CT card.bottom.should == :WB card.left.should == :MT card.right.should == :BT end This worked well for the lower-level "helper" methods: identifying the "sides" of a tile, determining if a tile can be validly placed in the grid, etc. But I ran into a problem when coding the actual algorithm to solve the puzzle. Since I didn't know valid possible solutions to the problem, I didn't know how to write a test first. I ended up writing a pretty ugly, untested, algorithm to solve it: def play_game working_states = [] after_1 = step_1 i = 0 after_1.each do |state_1| step_2(state_1).each do |state_2| step_3(state_2).each do |state_3| step_4(state_3).each do |state_4| step_5(state_4).each do |state_5| step_6(state_5).each do |state_6| step_7(state_6).each do |state_7| step_8(state_7).each do |state_8| step_9(state_8).each do |state_9| working_states << state_9[0] end end end end end end end end end So my question is: how do you use TDD to write a method when you don't already know the valid outputs? If you're interested, the code's on GitHub: Tests: https://github.com/mattdsteele/scramblesquares-solver/blob/master/golf-creator-spec.rb Production code: https://github.com/mattdsteele/scramblesquares-solver/blob/master/game.rb

  • Array of Structs Initialization....

    - by user69514
    Hi I am working on a program where I have to initialize a deck of cards. I am using a struct to represent a card. However I'm not filling it correctly as I get a bunch of zero's when I display the deck of cards. I believe my mistake is in this line but I'm not sure: struct card temp = {"Clubs", value, false}; The code: void initCards(){ int count = 0; int location = 0; const int hand = 12; //add hearts int value=2; while( count < hand ){ struct card temp = {"Hearts", value, false}; cards[location] = temp; value++; count++; } count = 0; //add diamonts value = 2; while( count < hand ){ struct card temp = {"Diamonds", value, false}; cards[count] = temp; value++; count++; } //add spades count = 0; value = 2; while( count < hand ){ struct card temp = {"Spades", value, false}; cards[count] = temp; value++; count++; } //add clubs count = 0; value = 2; while( count < hand ){ struct card temp = {"Clubs", value, false}; cards[count] = temp; value++; count++; } //print the deck for(int i=0; i<52; i++){ cout << cards[i].type << " " << cards[i].rank << endl; } }

  • JavaScript audio not playing outside of jQuery function

    - by user1814016
    I know the question title doesn't make much sense, but I can't think of a better way to put it. I am a newbie to jQuery and I'm using this code to fade in a <div> and play a sound: $(document).ready(function(){ $('#speech').fadeIn('medium', function() { play('msg_appear'); var sptx = $('<p class="stext">').text('There is nothing here.'); $('#speech').append(sptx); $('.stext').typeOut({marker: '', delay: 22}); }); }); This code runs fine however the sound plays after the fade-in is complete. I wanted it to play while it was fading in, so I tried placing the play() call outside of the fade-in function like this: $(document).ready(function(){ play('msg_appear'); $('#speech').fadeIn('medium', function() { However, now it's not playing at all. There's no errors on the JavaScript console so I'm unsure if it's a syntax error, and probably something obvious, but I don't know what. play() is a function I found to play audio, here it is if it matters at all. I placed it in the same file the above code is; right above the $(document).ready(). function play(sound) { if (window.HTMLAudioElement) { var snd = new Audio(''); if(snd.canPlayType('audio/ogg')) { snd = new Audio(sound + '.ogg'); } else if(snd.canPlayType('audio/mp3')) { snd = new Audio(sound + '.mp3'); } snd.play(); } else { alert('HTML5 Audio is not supported by your browser!'); } }

  • Sentence recognition and ability to answer with another sentence

    - by terabytest
    Hi. I'm looking into sentence recognition to make a program that should play voice clips from the game Team Fortress 2. I have .wav files and text files containing the transcription for every sound. What I'd like to make is a system that makes two characters of the game talk to each other (trough playing sound clips), and each one recognises the sense of what the other is saying and tries to answer with another of the available sound clips (trying its best to fit the sense of what it's trying to say) Is that possible in any way?

  • Stopping a SoundPlayer loop at the local level

    - by EvanRyan
    I'm working on setting up an alarm that pops up as a dialog with multiple sound file options the user can choose from. The problem I'm having is creating a sound player at the local level that I can close with a button. The problem I'm having is that the sound keeps looping when I close the form because the SoundPlayer doesn't exist within the button click event. here's what I have: void callsound() { if (SoundToggle == 0) // if sound enabled { if ((SoundFile == 0) && (File.Exists(@"attention.wav"))) { System.Media.SoundPlayer alarm = new System.Media.SoundPlayer(@"attention.wav"); alarm.PlayLooping(); } if ((SoundFile == 1) && (File.Exists(@"aahh.wav"))) { System.Media.SoundPlayer alarm = new System.Media.SoundPlayer(@"aahh.wav"); alarm.PlayLooping(); } } private void button1_Click(object sender, EventArgs e) { //alarm.Stop(); Only works if SoundPlayer declared at class level this.Close(); } Is there a way I can do what I want to do by declaring the SoundPlayer instances where I am? Or is there a way to declare it at the class level, and still be able to change the sound file based on user settings?

  • Do programmable Ethernet devices (think onboard CPU) really exist?

    - by PeterM
    I've heard from various people that programmable Ethernet cards exist and are easily available. However I have yet to be able to track down one of these mythical devices so I'm wondering if they're just that - a myth. Such a programmable card has a gigabit Ethernet interface, has a programmable CPU and connects to the host system via PCI Express. The problem area these cards address are low latency network applications where the card itself does the work and "reports back" to the operating system. Basically the card acts as a co-processor and handles all the low latency requirements on the card, thus avoiding the issues of writing low latency code in user-land - think 0.4ms - 0.5ms response times. So my question is, do these cards really exist and if so, where can I get my hands on one?

  • PC runs very slowly for no apparent reason

    - by GalacticCowboy
    I have a Dell Latitude D820 that I've owned for about 2.5 years. It is a Core 2 Duo T7200 2.0GHz, with 2 GB of RAM, an 80 GB hard drive and an NVidia Quadro 120M video card. The computer was purchased in late November of 2006 with XP Pro, and included a free upgrade to Vista Business. (Vista was available on MSDN but not yet via retail, so the Vista Business upgrades weren't shipped until March of '07.) Since we had an MSDN subscription at the time, I installed Vista Ultimate on it pretty much as soon as I got it. It ran happily until sometime in the spring of 2007 when Media Center (which I had never used except to watch DVDs) started throwing some kind of bizarre SQL (CE?) error. This error would pop up at random times just while using the computer. Furthermore, Media Center would no longer start. I never identified the cause of this error. I had the Vista Business upgrade by this time, so I nuked the machine, installed XP and all the drivers, and then the Vista Business upgrade. Again, it ran happily for a few months and then started behaving badly once again. Vista Business doesn't have Media Center, so this exhibited completely unrelated symptoms. For no apparent reason and at fairly random times, the machine would suddenly appear to freeze up or run very slowly. For example, launching a new application window (any app) might take 30-45 seconds to paint fully. However, Task Manager showed very low CPU load, memory, etc. I tried all the normal stuff (chkdsk, defrag, etc.) and ran several diagnostic programs to try to identify any problems, but none found anything. It eventually reached the point that the computer was all but unusable, so I nuked it again and installed XP. This time I decided to stick with XP instead of going to Vista. However, within the past couple of months it has started to exhibit the same symptoms in XP that I used to see in Vista. The computer is still under Dell warranty until December, but so far they aren't any help unless I can identify a specific problem. A friend (partner in a now-dead business) has an identical machine that was purchased at the same time. His machine exhibits none of these symptoms, which leads me to believe it is a hardware issue, but I can't figure out how to identify it. Any ideas? Utilities? Seen something similar? At this point I can't even identify any pattern to the behavior, but would be willing to run a "stress test"-style app for as long as a couple days if I had any hope that it would find something. EDIT July 17 I'm testing jerryjvl's answer regarding the video card, though I'm not sure it fully explains the symptoms yet. This morning I ran a video stress test. The test itself ran fine, but immediately afterward the PC started acting up again. I left ProcExp open and various system processes were consuming 50-60% of the CPU but with no apparent reason. For example, "services.exe" was eating about 40%, but the sum of its child processes wasn't higher than about 5%. I left it alone for several minutes to settle down, and then it was fine again. I used the "video card stability test" from firestone-group.com. Its output isn't very detailed, but it at least exercises the hardware pretty hard. EDIT July 22 Thanks for your excellent suggestions. Here is an update on what I have tried so far. Ran memtest86, SeaTools (Seagate), Hitachi drive fitness test, video card stability test (mentioned above). The video card test was the only one that seemed to produce any results, though it didn't occur during the actual test. I defragged the drive (again...) with JkDefrag I dropped the video card

  • How can I troubleshoot a "Hardware Malfunction" blue screen?

    - by AaronSieb
    My computer has suddenly started crashing to a blue screen with the following text: hardware malfunction call your hardware vendor for support *the system has halted* The crash occurs randomly during normal use. I have thus far always been able to reproduce it by transferring the contents of a large folder... But I'm not sure if this is caused by the file transfer, or simply because the transfer takes long enough for something else to trigger it. A bit about my hardware I have an dual core Intel CPU, and Asus motherboard. Video card is by nVidia, and connects via PCIe. My hard drives are in pairs, and connect via SATA to a RAID controller on the motherboard. They are configured to use a RAID0 configuration. What I've tried so far There is nothing in the Windows Event Log. WhoCrashed was unable to find any crash records. ScanDisk runs to completion (it launches prior to Windows load) and reports no errors. MemTest reports no errors (to 200% coverage). System temperatures are in the range of 40 to 50 degrees Celsius, with video card temperatures in the range of 60 to eighty degrees Celsius. I have stripped the system down to a minimal configuration (hard drive, video card, one memory module, motherboard, CPU, power supply). The problem still occurrs. However, this has allowed me to rule out a few components: It is not the video card because the problem still occurred after replacing the video card another one I had on hand. It is not the hard drive or anything software related because the problem occurred after a fresh installation of Windows on a replacement hard drive. It is not the hard drive cables because I replaced those with new ones and still had the problem. It is not the power supply because the problem still occurred after replacing the power supply with another one I had on hand. It is probably not the memory because I've tried three different memory modules in three different memory slots and was still able to replicate the issue. Is there anything I can do to confirm what's causing the issue? At the moment it seems as though it must be either the motherboard or CPU, but those are both difficult components to replace... In addition, both components are relatively new (two to three years old). I will gladly edit in any additional information I can get my hands on, and/or focus the question as I can find more details...

  • Windows 7 boot problem (with colorful blinking smilies)

    - by Ishmael Smyrnow
    I put my computer (Windows 7) to sleep, and a couple hours later, tried to wake it back up, but the monitor wouldn't come back on. I did a hard reset (held power button), but I still couldn't get the monitor to show anything. I plugged it into my laptop, and the monitor works fine. I then swapped out the video card with an older one I have. The monitor came on and started showing the boot process. However, shortly after the Windows 7 animated logo came up, the screen went blank, it made this weird beeping noise, and I seen the strangest thing ever. Small, colorful blocks started to fill my screen, and flash, as if something was loading. Inside of those blocks, were smilies (like the ASCII character kind). This continued for about a minute, then the computer rebooted. It scared the sh!t out of me. I've never had a virus before, and I'm savvy enough to keep myself from one, but I'm wondering if that's what it was. I've been using computers for ages, and never seen anything quite like this. Has anyone ever seen something like this? I'm doing hardware diagnostics before trying to boot into Windows again. Hopefully I can figure this out, but I thought I would consult the SU community while I wait on these results. -- UPDATE -- I did a Memory Diagnostic, which turned up nothing. I also booted into Safe Mode no problem, and scheduled a disk check on both of my drives (I dual boot XP & 7). I was feeling good, and tried putting my regular video card back in, and the monitor won't display anything with it. Also, even though the monitor displays nothing, the system sounds like it's booting up. However, I hear a clicking in one of my hard drives that isn't there with the older video card. Could this be a problem with my hard drive, video card, or PSU? PSU makes sense, except for the fact I've been using the same setup for over a year, and the video card doesn't require it's own power plug thing.

  • Why do some games randomly turn my screen a random solid color?

    - by Emlena.PhD
    When playing some games my computer will randomly have an error that I cannot fix without turning it off and back on again. The screen changes to one solid color, which varies (off the top of my head I can remember seeing solid green, magenta, etc..) and the sound blares a single tone. The sound sometimes briefly restores and I can still hear the game sounds and even hear and still be heard by people in my Mumble channel, but the screen doesn't right itself so I'm still blind. What's more is this happens in some games but not in others. While the game is actually running, not while I'm still in the menu. However, it does happen if I'm afk or idle but the game world is still rendering. Games where the error occurs: League of Legends World of Warcraft Trine The Sims 2 Dungeon Defenders Safe games: games where it has never occurred: Tribes: Ascend Star Wars: the Old Republic Battlefield 3 So relatively older games cause the problem while newer games do not? I cannot predict when it will happen, it just seems random. However, if it happens and I try playing the same game further after restart it does appear to occur more frequently after the first time. But if I switch to a safe game it doesn't continue happening. Both of my RAM sticks appear fine, flipped position or either one on their own and games still run, computer still boots. I would think over-heating, but then why not all games? ALso, sometimes it happens immediately after I start playing, within seconds of the 3D world booting up. I'm looking to upgrade very soon so I want to figure out what component or software is fubar and replace/repair it. Any suggestions or recommendations of tools would be helpful. Below is some system information. Dxdiag does not detect any problems. Operating System: Windows 7 Home Premium 64-bit (6.1, Build 7601) Service Pack 1 (7601.win7sp1_gdr.120305-1505) System Manufacturer: Gigabyte Technology Co., Ltd.

  • Thinkpad speaker turns mute - Linux Codec issue?

    - by Curlew
    At some point a few days ago the speakers on my Lenovo Thinkpad T410 (Model number: 2537A11) suddenly stopped working randomly. This error happens every time I watch a video or listen to a music file. The sound just abruptly stops. At the moment, I can't produce a single sound no matter what I do. I am using Debian GNU/Linux on this laptop and there doesn't appear to be anything else wrong (the fan is working, no abnormal heat (staying around ~40°C), no other obvious errors or problems). Here is the output of a nice program someone pointed me to: martin@martin:~/Downloads$ sudo python run.py --monitor Using temporary directory: /dev/shm/hda-analyzer You may remove this directory when finished or if you like to download the most recent copy of hda-analyzer tool. Downloading file hda_analyzer.py Downloading file hda_guilib.py Downloading file hda_codec.py Downloading file hda_proc.py Downloading file hda_graph.py Downloading file hda_mixer.py Downloaded all files, executing hda_analyzer.py Watching 1 cards ====================================== Sound is working normally and then it stops and the following lines appear: Diff for codec 0/0 (0x14f15069): --- +++ @@ -164,17 +164,17 @@ Power: setting=D0, actual=D0 Node 0x1f [Pin Complex] wcaps 0x400501: Stereo Pincap 0x00000010: OUT Pin Default 0x901701f0: [Fixed] Speaker at Int N/A Conn = Analog, Color = Unknown DefAssociation = 0xf, Sequence = 0x0 Misc = NO_PRESENCE Pin-ctls: 0x40: OUT - Power: setting=D0, actual=D0 + Power: setting=D3, actual=D3 Connection: 2 0x10* 0x11 Node 0x20 [Pin Complex] wcaps 0x400781: Stereo Digital Pincap 0x00000010: OUT Pin Default 0x40f001f0: [N/A] Other at Ext N/A Conn = Unknown, Color = Unknown DefAssociation = 0xf, Sequence = 0x0 Misc = NO_PRESENCE And now there is also an error in the dmesg output hda-intel: IRQ timing workaround is activated for card #0. Suggest a bigger bdl_pos_adj. I changed the bdl_pos_adj to various numbers (-1, 0, 64, 1024) and either there is no change at all or dmesg reports that the adjustment is too big. I wonder if this bdl_pos_adj is the real reason for the error. Here is my hardware information provided by alsa-info.sh website. Okay, i did some serious testing and even installed Windows and now i officially conclude that this is a hard-ware related issue with my Laptop speakers. Reason: The error occurs in my installed Debian Linux, an Ubuntu Live distribution and Windows XP No error-message appears in all of the OS. The sound just keeps running and i can't hear a thing. I tested different setups, including OSS, ALSA and the pulseaudio server on top If i use my new usb-headphones i can hear sound all the time without any sudden silences. So obviously, although hard to believe, my laptop speakers are not okay (never heard of similar cases). I'll award the bounty to anyone who can point me to good tutorials or the procedure how to exchange my T410 speakers (i still have warranty. The laptop was bought in Germany, but now i am in Denmark). Or to someone who can explain me the output from hda-analyzer (big log above).
