  • How can you convert audio (3.5mm) to S/PDIF?

    - by SSumner
    I have a monitor that I want to use as my 'TV' for my gaming system. I connect it via HDMI, so sound and video go through the monitor, but I want sound to my headphones, which travels via optical (S/PDIF) cable. The monitor (Dell U2713HM) has a 3.5mm audio jack on it for line out, but I couldn't find anything that simply plugs in an converts the analog audio signal to a digital one so I can plug in a S/PDIF cable. What sort of device do I need to do this? (I am not asking for shopping recommendations, merely what options allow this conversion. I would prefer the smallest option, as space is limited).

  • Anyone experiencing audio issues with VirtualBox on Linux and has a solution?

    - by DoxaLogos
    I've been using Virtualbox (now at 3.0.2) on Kubuntu (now at 9.04) for a while now, and I seem to have a problem when running Windows. Sometime after a while the audio will cut out in Kubuntu. The only way I can get it to recover is to make sure VirtualBox is completely shutdown and either going into multimedia under "system settings" and test the audio or restart. I'm wondering if anyone else here has experienced similar issues and has come up with a more elegant solution. I can't seem to find a reasonable one at virtualbox.org.

  • How to convert WinXP + Apps on RAID0 to use just one of the two RAID disks?

    - by chris5gd
    I have two 150GB SATA drives in hardware RAID 0, on which I have my C: (Win XP) and D: (installed apps). I'm migrating to Windows 7, but I want to keep my XP system until I've got it all running smoothly. So I want to: break the RAID move C: and D: to one of the drives (there's enough room) use the other drive for Win 7 boot into one or the other Clearly I can't move C: and D: after breaking the RAID, so I'm assuming I need to image the two partitions first, then break the RAID and restore the images to one of the drives. So my questions are: Is this possible? If so, what would be a good (free) imaging/restore tool? How do I ensure that the drive will boot after restoring the images? What sort of gotchas should I look out for? If there's a better solution than this, I'd be grateful for suggestions. Thanks!

  • copy a text file in C#

    - by melt
    I am trying to copy a text file in an other text file line by line. It seems that there is a buffer of 1024 character. If there is less than 1024 character in my file, my function will not copie in the other file. Also if there is more than 1024 character but less a factor of 1024, these exceeding characters will not be copied. Ex: 2048 character in initial file - 2048 copied 988 character in initial file - 0 copied 1256 character in initial file - 1024 copied Thks! private void button3_Click(object sender, EventArgs e) { // écrire code pour reprendre le nom du fichier sélectionné et //ajouter un suffix "_poly.txt" string ma_ligne; const int RMV_CARCT = 9; //délcaration des fichier FileStream apt_file = new FileStream(textBox1.Text, FileMode.Open, FileAccess.Read); textBox1.Text = textBox1.Text.Replace(".txt", "_mod.txt"); FileStream mdi_file = new FileStream(textBox1.Text, FileMode.OpenOrCreate,FileAccess.ReadWrite); //lecture/ecriture des fichiers en question StreamReader apt = new StreamReader(apt_file); StreamWriter mdi_line = new StreamWriter(mdi_file, System.Text.Encoding.UTF8, 16); while (apt.Peek() >= 0) { ma_ligne = apt.ReadLine(); //if (ma_ligne.StartsWith("GOTO")) //{ // ma_ligne = ma_ligne.Remove(0, RMV_CARCT); // ma_ligne = ma_ligne.Replace(" ",""); // ma_ligne = ma_ligne.Replace(",", " "); mdi_line.WriteLine(ma_ligne); //} } apt_file.Close(); mdi_file.Close(); }

  • Latex: Text cannot be placed below image

    - by Frederik Wordenskjold
    I love latex! But sometimes, it does not love me... I'm having a problem with an image and some text. I have this code: Some text...\\ \begin{figure}[ht] \centering \includegraphics[scale=0.75]{picture.jpg} \caption{The caption} \label{fig:picture} \end{figure} Some more text... Basically, I want this: Some text. (Above image in the code) [end of page / new page] image Some more text. (Below the image in the code) [start of new section] But, what the above code gives me is this: Some text. (Above image in the code) Some more text. (Below the image in the code) [end of page / new page] image [start of new section] Latex insists on putting everything but a new section above the image even though its below the image in the code. Its probably because the image floats on top - but whats my alternative? There's not enough space on the first page to display the image there, to I cannot use [h] as the float-alignment. I can "hack it", by creating an empty new section, like \section*{}, but this creates some white-space, which looks weird. Any suggestions?

  • Clearing input text feilds when clicked on in Flash (AS 2.0)

    - by rickstyphilis
    I have a problem where I want a text field that by default has the word NAME in it, to become empty when a user clicks on it. The text field has the instance name 'nam' and is inside a movie with the instance name 'input_text'. I've searched around and found samples of code where everyone keeps suggesting this: textboxinstancename.onSetFocus = function() { textboxinstancename.text = ""; }; should work. It seems to work for everyone else but me. I've tried using the following on the first frame of the 'input_text' movie with no luck: this.input_text.nam.onSetFocus = function() { this.input_text.nam.text = "" } I've tried putting this on the first frame of the scene, again with no result: _root.input_text.nam.onSetFocus = function() { _root.input_text.nam.text = "" } I've tried this in the same manner as the last respectively with both 'this' on the instance and '_root' on the scene (denoted by x): x.input_text.nam.onSetFocus = function() { if (x.input_text.nam.text == "NAME") { x.input_text.nam.text = ""; } }; Still no luck. Can anyone tell me what I might be doing wrong?

  • jQuery display text nested in paragraphs inside a div

    - by user961627
    I have HTML that looks something like this: <div class='textbox' data-title='Sometitle'> <div class='textareaedit'> <p><strong>Test sample text</strong></p> </div> </div> I'm sometimes going to have a few different <p> tags inside the textareaedit divs, and sometimes strong tags around the text inside the <p> (as in this example), and sometimes a span tag, and sometimes it's going to be without further tags inside the <p>. I want to iterate through each textbox on my page, grab its title and also the text nested inside <p> tags in textareaedit. I'm giving the output via console for testing. This is my jQuery code, but I get no output for the second console.log() line: $('.textbox').each(function() { $this = $(this); console.log($this.attr('data-title')+ ":\n"); $this.children('textareadit').children('p').each(function(){ console.log($(this).html()); // not giving any output, it's blank }); }); I tried $(this).text() as well, but no difference. You may think this example has the sample text inside <strong> tags within the <p>, but I've also tried the same example without the strong, where the text was the direct child of <p>, but it didn't make a difference. How can I capture the text?

  • [PHP/MySQL] How to create text diff web app

    - by Adam Kiss
    Hello, idea I would like to create a little app for myself to store ideas (the thing is - I want it to do MY WAY) database I'm thinking going simple: id - unique id of revision in database text_id - identification number of text rev_id - number of revision flags - various purposes - expl. later title - self expl. desc - description text - self expl . flags - if I (i.e.) add flag rb;65, instead of storing whole text, I just said, that whenever I ask for latest revision, I go again in DB and check revision 65 Question: Is this setup the best? Is it better to store the diff, or whole text (i know, place is cheap...)? Does that revision flag make sense (wouldn't it be better to just copy text - more disk space, but less db and php processing. php I'm thinking, that I'll go with PEAR here. Although main point is to open-edit-save, possiblity to view revisions can't be that hard to program and can be life-saver in certain situations (good ideas got deleted, saving wrong version, etc...). However, I've never used PEAR in a long-time or full-project relationship, however, brief encounters in my previous experience left rather bad feeling - as I remember, it was too difficult to implement, slow and humongous to play with, so I don't know, if there's anything better. why? Although there are bazillions of various time/project/idea management tools, everything lacks something for me, whether it's sharing with users, syncing on more PCs, time-tracking, project management... And I believe, that this text diff webapp will be for internal use with various different tools later. So if you know any good and nice-UI-having project management app with support for text-heavy usage, just let me know, so I'll save my time for something better than redesigning the weel.

  • Read huge free text docs in one file for lucene indexing

    - by Jun
    I have heaps of free text news docs in one big file. The structure of each news doc is like: (Header line) Category, Doc1, Date (day, month, year) (body text) ... ... ... (Header line) Category, Doc2, Date (day, month, year) (body text) ... ... ... If I extract each doc from the big file, it costs too much time and not efficient. Therefore, I decide to read the file line by line and feed information to lucene the same time. I write c# code to index each doc to lucene like: Streamreader sr = new Streamreader(file); string line = ""; while((line = sr.ReadLine()) != null) { How can I tell this line is a doc header line from text line and get the metadata and all the text lines of a doc for lucene to index. Also, the text is read by OCR which can not give correct line-separating. Captions are mixed with content text iterate the process till the end of the file } with thanks

  • How can I "bulk paste" a clipboard string of multi-line text into a readable ordered list?

    - by gunshor
    How can I "bulk paste" a clipboard string of multi-line text into a readable ordered list? I'm trying to demonstrate how to turn any string of multi-line text into an ordered list. The script (preferably JS) needs to respect: - carriage returns at the end of a line, to mean "that line ends here" - indentations at the beginning of a line, to mean "this is part of the item above it" - dashes at the beginning of a line, to mean "this is a task, and the line above it is its project"

  • I just don't get AudioFileReadPackets

    - by Eric Christensen
    I've tried to write the smallest chunk of code to narrow down a problem. It's now just a few lines and it doesn't work, which makes it pretty clear that I have a fundamental misunderstanding of how to use AudioFileReadPackets. I've read the docs and other examples online, and apparently I'm just not getting. Could you explain it to me? Here's what this block should do: I've previously opened a file. I want to read just one packet - the first one of the file - and then print it. But it crashes on the AudioFileReadPackets line: AudioFileID mAudioFile2; AudioFileOpenURL (audioFileURL, 0x01, 0, &mAudioFile2); UInt32 *audioData2 = (UInt32 *)malloc(sizeof(UInt32) * 1); AudioFileReadPackets(mAudioFile2, false, NULL, NULL, 0, (UInt32*)1, audioData2); NSLog(@"first packet:%i",audioData2[0]); (For clarity, I've stripped out all error handling.) It's the AFRP line that crashes out. (I understand that the third and fourth argument are useful, and in my "real" code, I use them, but they're not required, right? So NULL in this case should work, right?) So then what's going on? Any guidance would be much appreciated. Thanks.

  • record output sound in python

    - by aaronstacy
    i want to programatically record sound coming out of my laptop in python. i found PyAudio and came up with the following program that accomplishes the task: import pyaudio, wave, sys chunk = 1024 FORMAT = pyaudio.paInt16 CHANNELS = 1 RATE = 44100 RECORD_SECONDS = 5 WAVE_OUTPUT_FILENAME = sys.argv[1] p = pyaudio.PyAudio() channel_map = (0, 1) stream_info = pyaudio.PaMacCoreStreamInfo( flags = pyaudio.PaMacCoreStreamInfo.paMacCorePlayNice, channel_map = channel_map) stream = p.open(format = FORMAT, rate = RATE, input = True, input_host_api_specific_stream_info = stream_info, channels = CHANNELS) all = [] for i in range(0, RATE / chunk * RECORD_SECONDS): data = stream.read(chunk) all.append(data) stream.close() p.terminate() data = ''.join(all) wf = wave.open(WAVE_OUTPUT_FILENAME, 'wb') wf.setnchannels(CHANNELS) wf.setsampwidth(p.get_sample_size(FORMAT)) wf.setframerate(RATE) wf.writeframes(data) wf.close() the problem is i have to connect the headphone jack to the microphone jack. i tried replacing these lines: input = True, input_host_api_specific_stream_info = stream_info, with these: output = True, output_host_api_specific_stream_info = stream_info, but then i get this error: Traceback (most recent call last): File "./test.py", line 25, in data = stream.read(chunk) File "/Library/Python/2.5/site-packages/pyaudio.py", line 562, in read paCanNotReadFromAnOutputOnlyStream) IOError: [Errno Not input stream] -9975 is there a way to instantiate the PyAudio stream so that it inputs from the computer's output and i don't have to connect the headphone jack to the microphone? is there a better way to go about this? i'd prefer to stick w/ a python app and avoid cocoa.

  • jQuery textbox required validation based on another text box having text

    - by doug
    Pretty basic question, however, I am very new to jQuery and javascript in general. I have a jQuery validation that is requiring a text box to have text in it, if a checkbox is checked. <script type="text/javascript"> $(document).ready(function () { $("form").validate( { rules: { Comments: { required: "#IsAbnormal:checked" } }, messages: { Comments: { required: "Comments are required" } }, onkeyup: false, wrapper: "", errorLabelContainer: "#ErrorMessageBox" }); }); Pretty straight forward, if you check the IsAbnormal checkbox, it will throw a validation if there are no comments. What I am trying to do is require a textbox based on if another text box has any text in it, for instance require the old password if a user enters a new password into a textbox. Is there an easy way to get the required: "#NewPassword:NotBlank" to work?

  • How do I prevent ImageMagick convert from scaling images *up*?

    - by Kyle
    I'm using ImageMagick's convert tool to generate image thumbnails for a web application. I'm using notation like so: 600x600> The images are indeed scaled to 600px wide/tall (depending on the longer side) and proportions are properly maintained, however images less than 600px in either direction are scaled up — this behavior is not desired. Is there a way to prevent convert from scaling images up if the destination dimensions both exceed the original image size?

  • How do you convert a string to a node in XQuery?

    - by Sixty4Bit
    I would like to convert a string into a node. I have a method that is defined to take a node, but the value I have is a string (it is hard coded). How do I turn that string into a node? So, given an XQuery method: define function foo($bar as node()*) as node() { (: unimportant details :) } I have a string that I want to pass to the foo method. How do I convert the string to a node so that the method will accept the string.

  • Best practices: displaying text that was input via multi-line text box

    - by chris
    I have a multi-line text box. When users simply type away, the text box wraps the text, and it's saved as a single line. It's also possible that users may enter line breaks, for example when entering a "bulleted" lists like: Here are some suggestions: - fix this - remove that - and another thing Now, the problem occurs when I try to display the value of this field. In order to preserve the formatting, I currently wrap the presentation in <pre> - this works to preserve user-supplied breaks, but when there's a lot of text saved as a single line, it displays the whole text block as single line, resulting in horizontal scrolling being needed to see everything. Is there a graceful way to handle both of these cases?
