  • How to check Linux version with Autoconf?

    - by Goofy
    My program requires at least Linux 2.6.26 (I use timerfd and some other Linux-specific features). I have an general idea how to write this macro but I don't have enough knowledge about writing test macros for Autoconf. Algorithm: Run "uname --release" and store output Parse output and subtract Linux version number (MAJOR.MINOR.MICRO) Compare version I don't know how to run command, store output and parse it. Maybe such macro already exists and it's available (I haven't found any)?

  • MIgrating to Oracle

    We are using a JEE application and we are right now using Informix DB.Our code hits the DB with queries like "select first 10 * from test" Now as far as I know Oracle does not support 'first 10 *' kind of statements.We have more than 1000 queries like this.Should we manually change this or can have some manual customization?

  • How do you implement position-sensitive zooming inside a JScrollPane?

    - by tucuxi
    I am trying to implement position-sensitive zooming inside a JScrollPane. The JScrollPane contains a component with a customized 'paint' that will draw itself inside whatever space it is allocated - so zooming is as easy as using a MouseWheelListener that resizes the inner component as required. But I also want zooming into (or out of) a point to keep that point as central as possible within the resulting zoomed-in (or -out) view (this is what I refer to as 'position-sensitive' zooming), similar to how zooming works in google maps. I am sure this has been done many times before - does anybody know the "right" way to do it under Java Swing?. Would it be better to play with Graphic2D's transformations instead of using JScrollPanes? Sample code follows: package test; import java.awt.*; import java.awt.event.*; import java.awt.geom.*; import javax.swing.*; public class FPanel extends javax.swing.JPanel { private Dimension preferredSize = new Dimension(400, 400); private Rectangle2D[] rects = new Rectangle2D[50]; public static void main(String[] args) { JFrame jf = new JFrame("test"); jf.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); jf.setSize(400, 400); jf.add(new JScrollPane(new FPanel())); jf.setVisible(true); } public FPanel() { // generate rectangles with pseudo-random coords for (int i=0; i<rects.length; i++) { rects[i] = new Rectangle2D.Double( Math.random()*.8, Math.random()*.8, Math.random()*.2, Math.random()*.2); } // mouse listener to detect scrollwheel events addMouseWheelListener(new MouseWheelListener() { public void mouseWheelMoved(MouseWheelEvent e) { updatePreferredSize(e.getWheelRotation(), e.getPoint()); } }); } private void updatePreferredSize(int n, Point p) { double d = (double) n * 1.08; d = (n > 0) ? 1 / d : -d; int w = (int) (getWidth() * d); int h = (int) (getHeight() * d); preferredSize.setSize(w, h); getParent().doLayout(); // Question: how do I keep 'p' centered in the resulting view? } public Dimension getPreferredSize() { return preferredSize; } private Rectangle2D r = new Rectangle2D.Float(); public void paint(Graphics g) { super.paint(g); g.setColor(Color.red); int w = getWidth(); int h = getHeight(); for (Rectangle2D rect : rects) { r.setRect(rect.getX() * w, rect.getY() * h, rect.getWidth() * w, rect.getHeight() * h); ((Graphics2D)g).draw(r); } } }

  • How do you get Lighttpd to compress CodeIgniter's "clean urls"?

    - by ocdcoder
    I was looking at PageSpeed on my test website and noticed that Lighttpd wasn't compressing my HTML (but was compressing my javascript and css files). I'm assuming this is because I'm using CodeIgniter and it's clean url system and since the requests don't have file extensions, Lighttpd doesn't have the rule to compress it. That being the case, how do I get Lighttpd to compress my HTML? Is this something I shouldn't be doing? Or something I need to specially configure Lighttpd for?

    To describe this issue, the best would that you would test my application with following usecase: Application: http://ubuntuone.com/p/nF/ Open application; Click on the ""captioned button; Click on same button again; Click on the same button again. As you can see - URL is correctly detected in first expanding, but in any further is not. Hope to have fix for this issue with your help :)

  • How do I programmatically convert mp3 to an itunes-playable aac/m4a file?

    - by kwork
    I've been looking for a way to convert an mp3 to aac programmatically or via the command line with no luck. Ideally, I'd have a snippet of code that I could call from my rails app that converts an mp3 to an aac. I installed ffmpeg and libfaac and was able to create an aac file with the following command: ffmpeg -i test.mp3 -acodec libfaac -ab 163840 dest.aac When i change the output file's name to dest.m4a, it doesn't play in iTunes. Thanks!

  • Any good tutorials on using OAuth with Piston?

    - by Hank Gay
    I've looked at the relevant section of the Piston documentation, but it only seems to focus on how to turn it on, not what it would look like for clients or how to test it to verify it's working. The example only seems to use HTTP Basic and curl. Finally, Ned Batchelder's question makes it look like a tutorial is in order. Thanks.

  • XSLT Stylesheet works with a vbs script, but not Perl

    - by user2472274
    I have a program that is essentially a search application, and it exists in both VBScript and Perl form (I'm trying to make an executable with a GUI). Currently the search application outputs an HTML file, and if a section of text in the HTML is longer than twelve lines then it hides anything after that and includes a clickable More... tag. This is done in XSLT and works with VBScript. I literally copied and pasted the stylesheet into the Perl program that I'm using and it does everything right except for the More... tag. Is there any reason why it would be working with the VBScript but not Perl? I'm using XML::LibXSLT in the Perl script, and here is the template that is supposed to be creating the More... tag <xsl:template name="more"> <xsl:param name="text"/> <xsl:param name="row-id"/> <xsl:param name="cycle" select="1"/> <xsl:choose> <xsl:when test="($cycle &gt; 12) and contains($text,'&#13;')"> <span class="show" onclick="showID('SHOW{$row-id}');style.display = 'none';">More...</span> <span class="hidden" id="SHOW{$row-id}"> <xsl:call-template name="highlight"> <xsl:with-param name="text" select="$text"/> </xsl:call-template> </span> </xsl:when> <xsl:when test="contains($text,'&#13;')"> <xsl:call-template name="highlight"> <xsl:with-param name="text" select="substring-before($text,'&#13;')"/> </xsl:call-template> <xsl:text>&#13;</xsl:text> <xsl:call-template name="more"> <xsl:with-param name="text" select="substring-after($text,'&#13;')"/> <xsl:with-param name="row-id" select="$row-id"/> <xsl:with-param name="cycle" select="$cycle + 1"/> </xsl:call-template> </xsl:when> <xsl:otherwise> <xsl:call-template name="highlight"> <xsl:with-param name="text" select="$text"/> </xsl:call-template> </xsl:otherwise> </xsl:choose> </xsl:template>

  • fileToSTring keeps on returning " "

    - by karikari
    I managed to get this code to compile with out error. But somehow it did not return the strings that I wrote inside file1.txt and file.txt that I pass its path through str1 and str2. My objective is to use this open source library to measure the similarity between strings contains inside 2 text files. Inside the its Javadoc, its states that ... public static java.lang.StringBuffer fileToString(java.io.File f) private call to load a file and return its content as a string. Parameters: f - a file for which to load its content Returns: a string containing the files contents or "" if empty or not present Here's is my modified code trying to use the FileLoader function, but fails to return the strings inside the file. The end result keeps on returning me the "" . I do not know where is my fault: package uk.ac.shef.wit.simmetrics; import java.io.File; import uk.ac.shef.wit.simmetrics.similaritymetrics.*; import uk.ac.shef.wit.simmetrics.utils.*; public class SimpleExample { public static void main(final String[] args) { if(args.length != 2) { usage(); } else { String str1 = "arg[0]"; String str2 = "arg[1]"; File objFile1 = new File(str1); File objFile2 = new File(str2); FileLoader obj1 = new FileLoader(); FileLoader obj2 = new FileLoader(); str1 = obj1.fileToString(objFile1).toString(); str2 = obj2.fileToString(objFile2).toString(); System.out.println(str1); System.out.println(str2); AbstractStringMetric metric = new MongeElkan(); //this single line performs the similarity test float result = metric.getSimilarity(str1, str2); //outputs the results outputResult(result, metric, str1, str2); } } private static void outputResult(final float result, final AbstractStringMetric metric, final String str1, final String str2) { System.out.println("Using Metric " + metric.getShortDescriptionString() + " on strings \"" + str1 + "\" & \"" + str2 + "\" gives a similarity score of " + result); } private static void usage() { System.out.println("Performs a rudimentary string metric comparison from the arguments given.\n\tArgs:\n\t\t1) String1 to compare\n\t\t2)String2 to compare\n\n\tReturns:\n\t\tA standard output (command line of the similarity metric with the given test strings, for more details of this simple class please see the SimpleExample.java source file)"); } }

  • UITableView performance difference between Iphone 3G and 3GS ?

    - by gotye
    Hey guys, I managed to put my new app on an adhoc distribution but I just noticed that I only have 3GS's ... It is working quite good on the 3GS (could be a bit faster but that's fine) ... but do you think I should test it on the 3G ? I know there has been a lot of improvements between 3G and 3GS but would that infer on my uitableview performance ? Thanks, Gotye.

  • Any difference in performance/compatibility of different languages in PostgreSQL?

    - by Igor
    In nowadays the PostgreSQL offers plenty of procedural languages: pl/pgsql, pl/perl, etc Are there any difference in the speed/memory consumption in procedures written in different languages? Does anybody have done any test? Is it true that to use the native pl/pgsql is the most correct choice? How the procedure written in C++ and compiled into loadable module differs in all parameter w.r.t. the user function written with pl/* languages?
