  • Python Daemon Subprocess not working at boot

    - by Adam Richardson
    I am attempting to write a python daemon that will launch at boot. The goal of the script is to receive a job from our gearman load balancing server and complete the job. I am using the python-daemon module from pypi (http://pypi.python.org/pypi/python-daemon/). The nature of the job that it is completing is converting images in the orf (olympus raw image format) to jpeg. In order to accomplish this an outside program is used, ufraw in this case. The problem comes in when I start the daemon at boot, if I launch from the shell it runs perfectly and completes the work. When it starts at boot it is unable to launch the subprocess command. commandString = '/usr/bin/ufraw-batch --interpolation=four-color --wb=camera --compression=100 --output="' + outfile + '" --out-type=jpg --overwrite "' + infile + '"' args = shlex.split(commandString) process = subprocess.Popen(args).wait() I am not sure what I am doing wrong. Thanks for any help.

  • Fluxbox compiling problems after making a change.

    - by Jack
    I'm trying to make the change here: http://fluxbox-wiki.org/index.php?title=Howto_Make_dblclick_titlebar_maximize I am using the current git version of the fluxbox source. I assume that those instructions are perhaps no longer valid for the current git version. In the void FluxboxWindow::setupWindow() function I can see no references to CommandRef or frame. I would like to know if it is possible that I could work out where they should go in that function, with only having a limited knowledge? I am still trying to learn programming and don't know enough just yet to work out where they should go. I assume I can't just paste in the suggested lines anywhere in that function, but why not? I can paste the source if needed, but I am unsure where to paste to.

  • Node.js Creating and Deleting a File Recursively

    - by Matt
    I thought it would be a cool experiment to have a for loop and create a file hello.txt and then delete it with unlink. I figured that if fs.unlink is the delete file procedure in Node, then fs.link must be the create file. However, my code will only delete, and it will not create, not even once. Even if I separate the fs.link code into a separate file, it still will not create my file hello.txt. Below is my code: var fs = require('fs'), for(var i=1;i<=10;i++){ fs.unlink('./hello.txt', function (err) { if (err){ throw err; } else { console.log('successfully deleted file'); } fs.link('./hello.txt', function (err) { if (err){ throw err; } else { console.log('successfully created file'); } }); }); } http://nodejs.org/api/fs.html#fs_fs_link_srcpath_dstpath_callback Thank you!

  • Flowplayer RTMP streaming, mp4, Amazon Cloudfront and iPad/iPhone

    - by circey
    I've been working on a site where 2 video clips are streamed using Amazon Cloudfront and Flowplayer. You can see one video/page here: http://graemeclarkoration.org.au/gcorationp1.htm (works as a Highslide popup/modal window, hence the lack of adornment). While it works in all browsers and Android devices, I can't get it to work on an iPad or an iPhone; the page opens fine and the video box appears but the video never loads. Does anyone have any ideas how to fix or even why the video won't load? MTIA

  • Are there any reasons to make all fields and variables final?

    - by Roman
    In my current project I noticed that all class fields and variable inside methods are declared with final modifier whenever it's possible. Just like here: private final XMLStreamWriter _xmlStreamWriter; private final Marshaller _marshaller; private final OutputStream _documentStream; private final OutputStream _stylesStream; private final XMLStreamWriter _stylesStreamWriter; private final StyleMerger _styleMerger; public DocumentWriter(PhysicalPackage physicalPackage) throws IOException { final Package pkg = new Package(physicalPackage); final Part wordDocumentPart = pkg.createPart( "/word/document.xml", "application/vnd.openxmlformats-officedocument.wordprocessingml.document.main+xml", "http://schemas.openxmlformats.org/officeDocument/2006/relationships/officeDocument"); // styles.xml final Pair<Part, String> wordStylesPart = wordDocumentPart.createRelatedPart(...); ... } Are there any reasons to do so? p.s. As I know project is not supposed to be multithreaded (at least I've heard nothing about it).

  • jquery, moving the current item to the top

    - by azz0r
    Hello, The problem I'm having is that if the fourth item has a long description, it cuts off as it goes below #features. What I was hoping is someone would have a suggestion on how to make the current item selected to move to the top? Code below: <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <script type="text/javascript" src="/library/jquery/1.4.js"></script> <script> Model.FeatureBar = { current:0, items:{}, init: function init(options){ var me = this; me.triggers = [] me.slides = [] this.container = jQuery('#features'); jQuery('.feature').each(function(i){ me.triggers[i] = {url: jQuery(this).children('.feature-title a').href, title: jQuery(this).children('.feature-title'),description:jQuery(this).children('.feature-description')} me.slides[i] = {image: jQuery(this).children('.feature-image')} }); for(var i in this.slides){ this.slides[i].image.hide(); this.triggers[i].description.hide(); } Model.FeatureBar.goToItem(0); setInterval(function(){Model.FeatureBar.next()},5000); }, next: function next(){ var i = (this.current+1 < this.triggers.length) ? this.current+1 : 0; this.goToItem(i); }, previous: function previous(){ var i = (this.current-1 > 1) ? this.current-1 : this.triggers.length; this.goToItem(i); }, goToItem: function goToItem(i) { if (!this.slides[i]) { throw 'Slide out of range'; } this.triggers[this.current].description.slideUp(); this.triggers[i].description.slideDown(); this.slides[this.current].image.hide(); this.slides[i].image.show(); this.current = i; }, } </script> </head> <body> <div id="features"> <div class="feature current"> <div style="display: none;" class="feature-image"> <a href="google.com"><img src="/design/images/four-oh-four.png"></a> </div> <h2 class="feature-title"><a href="google.com">Item 3</a></h2> <p style="display: none;" class="feature-description"><a href="google.com">Item 3 description</a></p> </div> <div class="feature"> <div class="movie-cover"> <a href="/movie/movie"><img src="/image1" alt="" title=""></a> </div> <div style="display: block;" class="feature-image"> <a href="/rudeboiz-14-arse-splitters/movie"><img src="/images/Featured/rude.png"></a> </div> <h2 class="feature-title"><a href="/rude/movie">Item 2</a></h2> <p style="display: block;" class="feature-description"><a href="/rude/movie">Item 2 description</a></p> </div> <div class="feature"> <div style="display: none;" class="feature-image"> <a href="/pissed-up-brits/movie"><img src="/design/images/four-oh-four.png"></a> </div> <h2 class="feature-title"><a href="/pis/movie">Item 1</a></h2> <p style="display: none;" class="feature-description"><a href="/pis/movie">Item one description</a></p> </div> <div class="feature"> <div style="display: none;" class="feature-image"> <a href="what.com"><img src="/images/Featured/indie.png"></a> </div> <h2 class="feature-title"><a href="what.com">Item 4</a></h2> <p style="display: none;" class="feature-description"><a href="what.com">Item 4 description</a></p> </div> </div> </body> </html>

  • How do I set sys.excepthook to invoke pdb globally in python?

    - by saffsd
    From Python docs: sys.excepthook(type, value, traceback)¶ This function prints out a given traceback and exception to sys.stderr. When an exception is raised and uncaught, the interpreter calls sys.excepthook with three arguments, the exception class, exception instance, and a traceback object. In an interactive session this happens just before control is returned to the prompt; in a Python program this happens just before the program exits. The handling of such top-level exceptions can be customized by assigning another three-argument function to sys.excepthook. http://docs.python.org/library/sys.html How do I modify this globally so the default action is to always invoke pdb? Is there a configuration file I can change? I don't want to wrap my code to do this.

  • Construct a LPCWSTR on WinCE in C++ (Zune/ZDK)

    - by James Cadd
    What's a good way to construct an LPCWSTR on WinCE 6? I'd like to find something similar to String.Format() in C#. My attempt is: OSVERSIONINFO vi; memset (&vi, 0, sizeof vi); vi.dwOSVersionInfoSize = sizeof vi; GetVersionEx (&vi); char buffer[50]; int n = sprintf(buffer, "The OS version is: %d.%d", vi.dwMajorVersion, vi.dwMinorVersion); ZDKSystem_ShowMessageBox(buffer, MESSAGEBOX_TYPE_OK); That ZDKSystem_ShowMessageBox refers to the ZDK for hacked Zunes available at: http://zunedevwiki.org This line of code works well with the message box call: ZDKSystem_ShowMessageBox(L"Hello Zune", MESSAGEBOX_TYPE_OK); My basic goal is to look at the exact version of WinCE running on a Zune HD to see which features are available (i.e. is it R2 or earlier?). Also I haven't seen any tags for the ZDK so please edit if something is more fitting!

  • How does one programmatically create a topic w/ hornet q ?

    - by mP
    I have been looking at the org.hornetq.core.server package which seems to have the most interesting low level APIS relating to managing the server. The server session has a few methods labelled something Queue but none include Topic ... ServerSession void createQueue(SimpleString address, SimpleString name, SimpleString filterString, boolean temporary, boolean durable) throws Exception; void deleteQueue(SimpleString name) throws Exception interface QueueFactory Queue createQueue(long persistenceID, final SimpleString address, SimpleString name, Filter filter, boolean durable, boolean temporary); However i could not figure out how to create a topic. Am i missing something is a JMS topic implemented as a queue ?

  • How do negated patterns work in .gitignore?

    - by chrisperkins
    I am attempting to use a .gitignore file with negated patterns (lines starting with !), but it's not working the way I expect. As a minimal example, I have the folllowing directory structure: C:/gittest -- .gitignore -- aaa/ -- bbb/ -- file.txt -- ccc/ -- otherfile.txt and in my gitignore file, I have this: aaa/ !aaa/ccc/ My understanding (based on this: http://ftp.sunet.se/pub//Linux/kernel.org/software/scm/git/docs/gitignore.html) is that the file aaa/ccc/otherfile.txt should not be ignored, but in fact git is ignoring everything under aaa. Am I misunderstanding this sentence: "An optional prefix ! which negates the pattern; any matching file excluded by a previous pattern will become included again."? BTW, this is on Windows with msysgit 1.7.0.2.

  • Concatenating databases with Squeryl

    - by Pengin
    I'm trying to use Squeryl to take the contents of a table from one database, and append it to the equivalent table in another database. The primary key will have to be reassigned in the process, but I'm getting the error NULL not allowed for column "SIMID". Why is this? object Concatenator { def main(args: Array[String]) { Class.forName("org.h2.Driver"); val seshA = Session.create( java.sql.DriverManager.getConnection("jdbc:h2:file:data/resultsA", "sa", "password"), new H2Adapter ) val seshB = Session.create( java.sql.DriverManager.getConnection("jdbc:h2:file:data/resultsB", "sa", "password"), new H2Adapter ) using(seshA){ import Library._ from(sims){s => select(s)}.foreach{item => using(seshB){ sims.insert(item); } } } } case class Simulation( @Column("SIMID") var id: Long, val date: Date ) extends KeyedEntity[Long] object Library extends Schema { val sims = table[Simulation] on(sims)(s => declare( s.id is(unique, indexed, autoIncremented) )) } }

  • Can 3D OpenGL game written in Python look good and run fast?

    - by praavDa
    I am planning to write an simple 3d(isometric view) game in Java using jMonkeyEngine - nothing to fancy, I just want to learn something about OpenGL and writing efficient algorithms (random map generating ones). When I was planning what to do, I started wondering about switching to Python. I know that Python didn't come into existence to be a tool to write 3d games, but is it possible to write good looking games with this language? I have in mind 3d graphics, nice effects and free CPU time to power to rest of game engine? I had seen good looking java games - and too be honest, I was rather shocked when I saw level of detail achieved in Runescape HD. On the other hand, pygame.org has only 2d games, with some starting 3d projects. Are there any efficient 3d game engines for python? Is pyopengl the only alternative? Good looking games in python aren't popular or possible to achieve? I would be grateful for any information / feedback.

  • Navigating multiples files vi editor

    - by learner135
    According to http://www.lagmonster.org/docs/vi2.html the command :p would make vi go to the previous file. Unfortunately, this isn't working for me. However :n works and goes to the next page. What should I use to go to the previous file? For :p I get the message, Hit Return to continue and it stays in the same page. Thanks. Edit: I am sshing to an AIX box and using the vi in Ksh if that helps.

  • FileInputStream for a generic file System

    - by Akhil
    I have a file that contains java serialized objects like "Vector". I have stored this file over Hadoop Distributed File System(HDFS). Now I intend to read this file (using method readObject) in one of the map task. I suppose FileInputStream in = new FileInputStream("hdfs/path/to/file"); wont' work as the file is stored over HDFS. So I thought of using org.apache.hadoop.fs.FileSystem class. But Unfortunately it does not have any method that returns FileInputStream. All it has is a method that returns FSDataInputStream but I want a inputstream that can read serialized java objects like vector from a file rather than just primitive data types that FSDataInputStream would do. Please help!

  • Onclick starts gif animation and .mp3, how to sync across browsers

    - by user2958163
    So I am using a text-based jplayer (http://jplayer.org/latest/demo-04/) that I want to sync with a gif animation. Onclick the text link does two things -1. feed the jplayer an mp3 and 2. trigger an animation (via SwapImage). It is important for these two to start at the same time. Right now, this works perfectly in chrome/firefox but in IE and mobile browsers the audio lags considerably. I have tried with the audio preloaded (it is a small 40K mp3) and it makes no difference. I dont think its a bandwidth problem because the problem is the same on repeat clicks. Any pointers on how I can resolve this...

  • SimpleXML adding html into Hash tree

    - by Miriam Raphael Roberts
    Question: I have an xml file that I am pulling from the web and parsing. One of the items in the xml is a 'content' value that has HTML. I am using SimpleXML/XMLin to parse the file like so: $xml= eval { $data-XMLin($xmldata, forcearray = 1, suppressempty= +'') }; When I use Dumper to dump the hash, I dsicovered that SimpleXML is parsing the HTML into the hash tree. 'content' => { 'div' => [ { 'xmlns' => 'http://www.w3.org/1999/xhtml', 'p' => [ { 'a' => [ { 'href' => 'http://miamiherald.typepad.com/.a/6a00d83451b26169e20133ec6f4491970b-pi', 'style' => 'FLOAT: left', 'img' => [ etc..... This is not what I want. I want to just grab content inside of this entry. How do I do this?

  • MVC Entity Model not showing my table

    - by Jessica
    I have a database with multiple tables, and some basic relationships. Here is an example of the problem I am having: My Database: **Org** ID Name etc **Detail1** ID D1name **Org_Detail1** Org_ID Detail1_ID **Detail2** ID D2Name **Org_Detail2** Org_ID Detial1_ID BooleanField My problem is, the Org_detail1 table is not showing up in the entity model, but the Org_Details2 table does. I thought it may have been because the Org_Detail1 table only contains two ID fields that are both primary keys, while the Org_Details2 table contains 2 primary key ID fields as well as a boolean field. If I add a dummy field to Org_detail1 and update it, it still won't show up and wont allow me to add a new entity relating to the Org_Detail1 table. The table won't even show up in the list, but it is listed under the tables. Is there any solution to get this table to appear in my model?

  • Installing Refinery CMS on Windows

    - by PEBKAC
    Hi all, I cannot get Refinery cms to install on my crappy Vista machine. I have followed all instructions on http://github.com/resolve/refinerycms but the bundler doesn't work because there is not gemfile (I have copied the gemfile from github but it fails at rmagick gem) and have also tried the command line instructions but it fails at rake db:setup. I have tried installing all required gems myself but this makes no difference. Can anyone give me a quick step by step on how to get it running? I have now completely removed ruby so can start afresh. I have the installers from rubyinstaller.org and have tried with both 1.8.7 and 1.9. I have mysql 5.1 installed. Much appreciated!

  • Create a Sin wave line with Processing

    - by Nintari
    Hey everybody, first post here, and probably an easy one. I've got the code from Processing's reference site: float a = 0.0; float inc = TWO_PI/25.0; for(int i=0; i<100; i=i+4) { line(i, 50, i, 50+sin(a)*40.0); a = a + inc; } http://processing.org/reference/sin_.html However, what I need is a line that follows the curve of a Sin wave, not lines representing points along the curve and ending at the 0 axis. So basically I need to draw an "S" shape with a sin wave equation. Can someone run me through how to do this? Thank you in advance, -Askee

  • How to ensure that no non-ascii unicode characters are entered ?

    - by Jacques René Mesrine
    Given a java.lang.String instance, I want to verify that it doesn't contain any unicode characters that are not ASCII alphanumerics. e.g. The string should be limited to [A-Za-z0-9.]. What I'm doing now is something very inefficient: import org.apache.commons.lang.CharUtils; String s = ...; char[] ch = s.toCharArray(); for( int i=0; i<ch.length; i++) { if( ! CharUtils.isAsciiAlphanumeric( ch[ i ] ) throw new InvalidInput( ch[i] + " is invalid" ); } Is there a better way to solve this ?

  • Pig: Count number of keys in a map

    - by Donald Miner
    I'd like to count the number of keys in a map in Pig. I could write a UDF to do this, but I was hoping there would be an easier way. data = LOAD 'hbase://MARS1' USING org.apache.pig.backend.hadoop.hbase.HBaseStorage( 'A:*', '-loadKey true -caching=100000') AS (id:bytearray, A_map:map[]); In the code above, I want to basically build a histogram of id and how many items in column family A that key has. In hoping, I tried c = FOREACH data GENERATE id, COUNT(A_map); but that unsurprisingly didn't work. Or, perhaps someone can suggest a better way to do this entirely. If I can't figure this out soon I'll just write a Java MapReduce job or a Pig UDF.

  • NETBEANS JAVADB - How do I integrate a JavaDB DataBase into my main Java Package

    - by Stefanos Kargas
    JAVA I am working on a desktop application which uses JavaDB. I am using NetBeans 6.8 and JDK 6 Update 20 I created the database I need and connected to it through my application using ClientDriver: String driver = "org.apache.derby.jdbc.ClientDriver"; String connectionURL = "jdbc:derby://localhost:1527/myDB;create=true;user=user;password=pass"; try { Class.forName(driver); } catch (java.lang.ClassNotFoundException e) { e.printStackTrace(); } try { schedoDBConnection = DriverManager.getConnection(connectionURL); } catch (Exception e) { e.printStackTrace(); } This works fine. But in that case the service of the database comes from NetBeans. If I move my application to another PC I won't be able to access my database. How can I integrate my JavaDB into my application?

  • Is it possible to parse a stylesheet with Nokogiri?

    - by wbharding
    I've spent my requisite two hours Googling this, and I can not find any good answers, so let's see if humans can beat Google computers. I want to parse a stylesheet in Ruby so that I can apply those styles to elements in my document (to make the styles inlined). So, I want to take something like <style> .mystyle { color:white; } </style> And be able to extract it into a Nokogiri object of some sort. The Nokogiri class "CSS::Parser" (http://nokogiri.rubyforge.org/nokogiri/Nokogiri/CSS/Parser.html) certainly has a promising name, but I can't find any documentation on what it is or how it works, so I have no idea if it can do what I'm after here. My end goal is to be able to write code something like: a_web_page = Nokogiri::HTML(html_page_as_string) parsed_styles = Nokogiri::CSS.parse(html_page_as_string) parsed_styles.each do |style| existing_inlined_style = a_web_page.css(style.declaration) || '' a_web_page.css(style.declaration)['css'] = existing_inlined_style + style.definition end Which would extract styles from a stylesheet and add them all as inlined styles to my document.
