• Ubuntu Studio 10.4 boots to terminal mode only

  - by Don

  I did clean install from ISO DVD. It boots only to command line asking for login. After I login I enter STARTX and desktop appears and some of the studd actually works, but there are a lot of problems: there is no way to reboot or shut down except to stopx/logoff and enter shutdown sound system doesn't respond pulse audio volume control gives "connection failed, connection refused" DVD drives not available GDebi Package installer is grayed out and so I can't use it (but synaptic package manager works OK) Software Center won't start when clicked -- it just stops trying DBus cant run because it says /usr/local/var/run/dbus/system_bus_socket file not found (also /var/run/dbus/system_bus_socket file not found) There's just a lot of things wrong and I can't help but think something is missing or was mis-coded in the distro so that there are typos in some script somewhere. If anyone can tell me where to begin to untangle this mess I'd appreciate it, but I think it all begins when it can't start the GUI automatically and I need to enter STARTX.

• Windows7: Which app has a notification sound with 3 descending notes?

  - by Eric

  Brand new Win7 box loaded with the usual dev tools -- VS2008, Firefox, Chatzilla, Thunderbird, emacs, Pidgin, Putty, iTunes, SharpReader. Every couple of minutes, I get an audio notification consisting of three rising notes, maybe a middle-C-G-F on a piano (I don't have a piano handy, and don't have time to use GarageBand to try to figure it out). Nothing in the notification bar is flashing when this happens. The sound isn't in any of the Windows Sound control panel applets. And it's not in C:\Windows\Media, so it's most likely coming from a non-Microsoft app. Is this familiar to anyone?

• Installing maven on Ubuntu by manual download

  - by WebDevHobo

  To install Maven, I downloaded the latest version from the website and then followed these steps: http://maven.apache.org/download.html#Installation The last step, the version control, does not work. It says that 'mvn' is currently not installed and that I should type sudo apt-get install maven2 If I go directly to the mvn file itself, it does work: root@ubuntu:~# /usr/local/apache-maven/apache-maven-2.2.1/bin/mvn --version Apache Maven 2.2.1 (r801777; 2009-08-06 12:16:01-0700) Java version: 1.6.0_21 Java home: /usr/java/jdk1.6.0_21/jre Default locale: en_US, platform encoding: UTF-8 OS name: "linux" version: "2.6.32-25-generic" arch: "i386" Family: "unix" So, what am I doing wrong here? Or what would and apt-get install do extra that I might have forgotten?

• Windows Media Player functionality for Ubuntu

  - by Xeoncross

  I have way to many music files to bother with setting up playlists. Especially since my files locations keeps changing as I move stuff around and swap between different computers, different mount points, and even different Operating Systems! So managing my media with any application is doomed to failure. However, since I still want to listen to the music I usually just select all the files I want to play at a time and then right-click to open them in a media player. Works great in windows media player and places all the tracks in a temp playlist on the sidebar. Fails in ubuntu using Rhythmbox since it doesn't understand "temp" playlists and just keeps adding files to your FULL listing of all sings on your whole computer. I have over three copies of some tracks now in my audio collection - and all of them are now invalid because the location of the files has changed. So what media player (for Ubuntu) works well with just temporary playlists and will allow me to open up my files without adding them to a collection?

• What do I need to use an XBOX 360 with my PC monitor and speakers?

  - by heishe

  I've been thinking about getting an XBOX 360, mostly for games on XBLA or some exlusive titles, since they're relatively cheap now to get used. But I'm a student and live in a small apartment that has no TV, and no place to put a new TV (money to buy one wouldn't be a problem), so I've been thinking to use the console with my PC monitor and my speakers. My monitor only has HDMI and VGA input (no direct DVI), so I'm guessing I somehow need to split the audio and video signals coming from the XBox (or does the XBox have a direct 720p VGA output + external connectors for my speakers?). What do I need to make this happen?

• Is it possible to remove buzzing from headphones which occurs only when scrolling / window redrawing?

  - by Billy ONeal

  Whenever a lot of drawing is happening on my laptop a buzzing noise is emitted by the sound hardware, which is clearly audible with headphones (similar to this question or this one). I've tried both the headphone jack on the laptop itself, and also on the dock. I've used other laptops and they all seem to have similar problems here, which leads me to believe this is more a function of relatively low quality laptop sound hardware than any fault with the headphones or this laptop in particular. I'm curious if there's some piece of hardware I might use to eliminate the buzzing. For instance, would an external USB sound device fix the problem or is it likely subject to the same kinds of issues? Would a simple filter/choke on the headphone cord itself possibly help? Or is one simply stuck with poor quality audio from laptops period?

• HTTP Live Streaming Broadcast

  - by user761389

  I'm designing an app for streaming video from a device (e.g. iPhone) via a server to one or more devices and have been researching Apples HTTP Live Streaming protocol. One thing that isn't clear is whether it is possible to stream live video (with audio) to the server and then have it streamed simultaneously in real time to the client devices. From reading the documentation and technical notes from Apple it seems like the index file needs to be created before the segmented video files can be served to a client. Is this right? If so maybe HTTP Live Streaming isn't suitable in this case, what other technologies or software should I consider? Thanks

• Does Windows 8 Need New, Specialized Drivers?

  - by Synetech

  It seems like an obvious question, but I’m having a difficult time finding out if Windows 8, with all its changes, will require new, specialized drivers. I see that a lot of manufacturers have started releasing Windows 8-specific drivers for their hardware, but what about those that are not, will Windows XP or 7 drivers work or have they changed the driver/system/security architecture again, thus requiring new drivers? The closest thing I could find to an answer was a thread in which it was mentioned that the display driver model was again updated, thus requiring new display drivers, but not much else (e.g., audio cards, printers, chipsets, etc.)

• games and movies become too slow after some time

  - by ishaq

  On my gaming desktop, I was fixing my desktop's power supply when something seemed to burn (I got that stinging burning smell). However when I turned ON the computer (it was OFF before), everything seemed to be fine. However, I have noticed that now it becomes too slow if I play a game or movie on it. I am talking about the computer becoming painfully slow after about 5 minutes into the movie/game (it works fine otherwise e.g. browsing), it becomes so slow I can see individual frames from movies/games. What could be the problem? A fried video card? friend memory (RAM), something else? My system's configuration is: Intel Core i7 CPU 3.40GHz 8GB DDR3 RAM 2TB WDC HDD NVIDIA GeForece GT 220 (1GB) Thermal Take Commander MS1 Chassis ( http://www.thermaltakeusa.com/Product.aspx?S=1394&ID=2051 ) mainboard: Intel DH67CL AAG10212-208 Realtek High Definition Audio

• How to know when the Client is disconnected from Server in C#?

  - by menacheb

  Hi, I have a Client-Server program in C#. Here is the Server's code: ... String dataFromClient = ""; NetworkStream networkStream; TcpClient clientSocket; bool transfer = true; ... while (transfer) { networkStream = clientSocket.GetStream(); networkStream.Read(bytesFrom, 0, (int)clientSocket.ReceiveBufferSize); dataFromClient = System.Text.Encoding.ASCII.GetString(bytesFrom); dataFromClient = dataFromClient.Substring(0, dataFromClient.IndexOf("$")); .... } I want to make a condition that stop the loop when the Client is disconnected. How can I do that? Many thanks,

• itunes equalizer per track settings

  - by DA

  I'm a little confused about iTune's ability to set eq presets on a per-song basis. I have a song that I open, set to a given EQ preset, then close. When I play this song, however, the audio isn't being adjusted. If I open the EQ and turn it 'on', though, it then obeys the song's eq setting. Of course, if I leave the EQ on, then songs that do not have their own EQ setting default to whatever the EQ was originally set at. Not a HUGE deal, but it means that I would then normally have to have EQ always turned on, set to flat, so that any song that I HAVE given a EQ setting to will use it. Am I understanding how that works correctly? Is there a way to have individual songs use their EQ setting without having to turn on the EQ for everything?

• DELL U2410 Monitor(Display Port) & Graphic card

  - by Anj

  I was looking for a 24" monitor and bought the Dell 24" inch ultra sharp monitor which has DisplayPort( new keyword for me) seems it is equivalent to HDMI. Now I would like to enhance the display capabilities for my laptop and desktop(both have VGA output as of now). Couple of questions in mind: Is there a single HD graphic card which i could use for both desktop and laptop? I understand it has to be external but if its costly then I would stick on internal graphic card for my desktop. Please recommend external if its cost effective else I would go for internal one(Budget is around $70 or Rs 4000. Is there a HD card which I could use for both HD video and 5.1 channel audio output? I generally use the computer for office work/ listening music and watching movies, not gaming.

• Reducing lag when downloading large amount of data from webpage

  - by Mahir

  I am getting data via RSS feeds and displaying each article in a table view cell. Each cell has an image view, set to a default image. If the page has an image, the image is to be replaced with the image from the article. As of now, each cell downloads the source code from the web page, causing the app to lag when I push the view controller and when I try scrolling. Here is what I have in the cellForRowAtIndexPath: method. NSString * storyLink = [[stories objectAtIndex: storyIndex] objectForKey: @"link"]; storyLink = [storyLink stringByTrimmingCharactersInSet:[NSCharacterSet whitespaceAndNewlineCharacterSet]]; NSString *sourceCode = [NSString stringWithContentsOfURL:[NSURL URLWithString:storyLink] encoding:NSUTF8StringEncoding error:&error]; NSString *startPt = @"instant-gallery"; NSString *startPt2 = @"<img src=\""; if ([sourceCode rangeOfString:startPt].length != 0) { //webpage has images // find the first "<img src=...>" tag starting from "instant-gallery" NSString *trimmedSource = [sourceCode substringFromIndex:NSMaxRange([sourceCode rangeOfString:startPt])]; trimmedSource = [trimmedSource substringFromIndex:NSMaxRange([trimmedSource rangeOfString:startPt2])]; trimmedSource = [trimmedSource substringToIndex:[trimmedSource rangeOfString:@"\""].location]; NSURL *url = [NSURL URLWithString:trimmedSource]; NSData *data = [NSData dataWithContentsOfURL:url]; UIImage *image = [UIImage imageWithData:data]; cell.picture.image = image; Someone suggested using NSOperationQueue. Would this way be a good solution? EDIT: - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { static NSString *MyIdentifier = @"FeedCell"; LMU_LAL_FeedCell *cell = [tableView dequeueReusableCellWithIdentifier:MyIdentifier]; if (cell == nil) { NSArray *nib = [[NSBundle mainBundle] loadNibNamed:@"LMU_LAL_FeedCell" owner:self options:nil]; cell = (LMU_LAL_FeedCell*) [nib objectAtIndex:0]; } int storyIndex = [indexPath indexAtPosition: [indexPath length] - 1]; NSString *untrimmedTitle = [[stories objectAtIndex: storyIndex] objectForKey: @"title"]; cell.title.text = [untrimmedTitle stringByTrimmingCharactersInSet:[NSCharacterSet whitespaceCharacterSet]]; CGSize maximumLabelSize = CGSizeMake(205,9999); CGSize expectedLabelSize = [cell.title.text sizeWithFont:cell.title.font constrainedToSize:maximumLabelSize]; //adjust the label to the the new height.

• How to play multiple videos side-by-side synchronized?

  I've got 3 videos, all 3 have the same time, same amount of frames, and they only differ in terms of encoding quality. Now I need them to run side-by-side in synchronized fashion for evaluation purposes. Meaning when I press "play" BOTH! videos should start. Analogically for stop, forward, backward. Anyone know any player capable of doing that? By that I mean playing more than 1 video side-by-side... Platform: Win7

• Can I use my old Sony Handycam TRV815 as a web cam?

  - by Optimal Solutions

  Has anyone ever used their old Sony Handycam (or maybe any older hand-held camcorder) as a web cam? As in streaming the live video from the cam to a web server (local or remote/Internet). My TRV815 has a pretty darn good picture quality for its time.. Via USB or Ethernet. It has S-Video but I think that is input. It has RCA out (white/red for audio and yellow for video) and I have used that to display to my TV. I have web cams already but was wondering if I could put this one to use also just for kicks..

• bluray playback stuttering/choppy on mac

  - by smashtastic

  I have had a few issues with bluray playback on mac with the following details: 2.4 GHz Core 2 duo NVidia 8600 m GT 256 mb ram 4 GB ram OSX Lion 10.7.5 Using VLC 2.03 for playback Files either mounted as a disc or stored on hardisk. I have tried various sources and playback is always choppy and stutters. Where the video and audio pause for a few seconds before resuming ok. If I transcode the same bluray files into mkv files play back is seemless. I am not applying any compression and the resolution is the same as is the nominal file size. For a recent example 11.2 GB m2ts and 10.5 GB mkv file. This stuttering and choppy playback of bluray files through VLC has occured for a number of different sources. For each of these sources transcoding to mkv solves the stuttering/choppiness. Any ideas on how to resolve this?

• Share files and catelog them across a server

  Hi all, here is what I am looking for, I use a number of software packages when creating online learning courses. I have a huge number of courses and they use text, audio files, images and video files. I am looking for somthing that I can install on our server and upload the content, index, tag and categorise and enter a description so that when a screen print has to be changed for example I can find all the places that I used the image so that I can go in and change the image without having to check every file that I have created over the last year. An open source solution would be great or something that isn't to expensive. Thank you for any suggestions you can make.
