  • Can I use only a HDMI monitor?

    - by Felix
    I recently found out there are such things as PC monitors with TV capabilities (or TVs that can be PC monitors), and the idea kind of tickles my fancy. I'm thinking of getting one of these gadgets, and if I do, I will connect it to my PC via HDMI (my graphics card has builtin HDMI), so that I also get sound to the TV. The reason for this is because I have a 2.1 sound system which I want to use both on the PC and the TV. Basically, I want the configuration to look like this: Cable --------> TV --> 2.1 Sound System PC --HDMI--> TV --> 2.1 Sound System My question is: can I use a setup like this? Can I not have a classic VGA monitor? Will I be able to see non-graphical interfaces (such as the BIOS, GRUB, a Linux terminal, ...) through HDMI on the TV? I use Windows 7 and Ubuntu.

  • hdmi AC-3 audio broke after upgrading from 11.10 to 12.04.3

    - by Jim LastName
    I just updated my MythBuntu 11.10 to 12.04.3. Now, when I try to play 5.1 content (ripped DVD), my TV (and receiver) plays a "chattering" sound. I check my receiver and the digital dolby light isn't on--it's in PCM mode. So, either the audio is getting sent as AC-3, but the TV and receiver think it's PCM or the AC-3 audio got converted to multichannel PCM and they can't handle it. My setup: hdmi cable from htpc to TV. TV has an s/pdif output to my receiver. I know TV sends AC-3 audio out correctly because I see digital dolby light come on when I view a digital TV channel and PCM come on when I view an old analog channel. I can connect s/pdif from my htpc to my receiver and the digital dolby light comes on and it can decode the audio just fine. It's just not sending it right over hdmi. Now for some hints to the issue: I noticed in MythTV audio setup when I select alsa:hdmi.... the description only lists 2 channel PCM audio capability. speaker-test -Dhdmi:PCH -c6 errors about a bad channel count (only -c2 works). Finally, I tried vlc and it does the same chattering sound. These all make me think this isn't a MythTV issue, it's something lower than that. I think the best way to troubleshoot this is to start at the drivers and check each layer, one at a time all the way to alsa. I just don't know what the layers are and how to do it. So, I need to find some audio troubleshooting guide to assist me. Or, if one doesn't exist, I'd appreciate some steps. Thanks much, Jim

  • Why is it assumed that send may return with less than requested data transmitted on a blocking socke

    - by Ernelli
    The standard method to send data on a stream socket has always been to call send with a chunk of data to write, check the return value to see if all data was sent and then keep calling send again until the whole message has been accepted. For example this is a simple example of a common scheme: int send_all(int sock, unsigned char *buffer, int len) { int nsent; while(len 0) { nsent = send(sock, buffer, len, 0); if(nsent == -1) // error return -1; buffer += nsent; len -= nsent; } return 0; // ok, all data sent } Even the BSD manpage mentions that ...If no messages space is available at the socket to hold the message to be transmitted, then send() normally blocks... Which indicates that we should assume that send may return without sending all data. Now I find this rather broken but even W. Richard Stevens assumes this in his standard reference book about network programming, not in the beginning chapters, but the more advanced examples uses his own writen (write all data) function instead of calling write. Now I consider this still to be more or less broken, since if send is not able to transmit all data or accept the data in the underlying buffer and the socket is blocking, then send should block and return when the whole send request has been accepted. I mean, in the code example above, what will happen if send returns with less data sent is that it will be called right again with a new request. What has changed since last call? At max a few hundred CPU cycles have passed so the buffer is still full. If send now accepts the data why could'nt it accept it before? Otherwise we will end upp with an inefficient loop where we are trying to send data on a socket that cannot accept data and keep trying, or else? So it seems like the workaround, if needed, results in heavily inefficient code and in those circumstances blocking sockets should be avoided at all an non blocking sockets together with select should be used instead.

  • how to generate unique numbers less than 8 characters long.

    - by loudiyimo
    hi I want to generate unique id's everytime i call methode generateCustumerId(). The generated id must be 8 characters long or less than 8 characters. This requirement is necessary because I need to store it in a data file and schema is determined to be 8 characters long for this id. Option 1 works fine. Instead of option 1, I want to use UUID. The problem is that UUID generates an id which has to many characters. Does someone know how to generate a unique id which is less then 99999999? option 1 import java.util.HashSet; import java.util.Random; import java.util.Set; public class CustomerIdGenerator { private static Set<String> customerIds = new HashSet<String>(); private static Random random = new Random(); // XXX: replace with java.util.UUID public static String generateCustumerId() { String customerId = null; while (customerId == null || customerIds.contains(customerId)) { customerId = String.valueOf(random.nextInt(89999999) + 10000000); } customerIds.add(customerId); return customerId; } } option2 generates an unique id which is too long public static String generateCustumerId() { String ownerId = UUID.randomUUID().toString(); System.out.println("ownerId " + ownerId); return ownerId }

  • How to resize div element less than its content?

    - by andDaviD
    I have a table and there is a TreeView in a cell. Here is my code: <style> #leftPanel { width:60px; height:'100%'; border:1px solid red; background:yellow; } <style> <table> <tr> <td> <div id="leftPanel"> <asp:PlaceHolder runat="server" ID="TreeView" /> <%-- Here is a TreeView --%> </div> </td> </tr> <%-- other code --%> <table> $(function () { $('#leftPanel').resizable( { handles: 'e, w' }); }); I can't reduce the size of my div less then the size of my TreeView. What code need I write to allow leftPanel to be less than the size of TreeView ? It is necessary if TreeView node's text too long.

  • QTableWidget: How can I get tighter lines with less vertical spacing padding?

    - by Dirk Eddelbuettel
    The QTableWdiget is fabulous for simple grid displays. Changing colors, fonts, etc is straightforward. However, I did not manage to give the grid a 'tighter' look with less vertical whitespace. I see that the Qt documentation talks (eg here) about margin border padding around widgets, but when I set these I only get changes around the entire grid widget rather than inside. How can I set this (with a style sheet, or hard-coded options) directly to make the QTableWidget display tighter?

    How can I make xmlpp::DomParser be less verbose on errors? Right now, if parsing fails, I get a bunch of text printed to my console and I'd just as soon have that not be visible. Entity: line 1: parser error : Opening and ending tag mismatch: feed line 1 and fed <feed><entry id='5' /></fed> I don't see a lot of options for xmlpp::DomParser but I have to believe this is something that can be disabled/tweaked.

  • How do you check to see if a variable has changed every second or less in objective c?

    - by James
    I am using an if statement to check the value of a BOOLEAN when i click on a button. When the button is clicked if the value is false i want to display a UIActivityIndicator and if the value is true i want to push the new view. I can do this fine but i want the view to change automatically when the BOOLEAN Becomes true if the user has already clicked the button. So my question is how do you check to see if a value has changed everysecond or less?
