  • Run Linux command as predefined user

    - by vijay.shad
    Hi all, I have created a shell script to start a server program. startup.sh start When above command will executes, it will try starts the server as adminuser. To achieve this my script has written like this. SUBIT="su - adminuser -c " SERVER_BOX_COMMAND_A="Server" ############## # Function to start cluster function start(){ $SUBIT "$SERVER_BOX_COMMAND_A" } When i execute the command it asks for password. Is there any other way to do this so, it will not ask for password. I have seen this behavior in Jboss startup script provided on jboss. That script changes the user to jboss and then starts the jboss server. I wanted my script to behave same way.

  • Any good tools or tips for fuzz testing Windows forms applications?

    - by Ogre Psalm33
    I'm maintaining a ~300K LOC C# legacy thick-client application with a Windows.Forms interface. The app is full of little bugs and quirks. For example, I recently discovered a bug where if a users edits and tabs (not clicks) through cells on a DataViewGrid, and leaves the a certain cell selected, the app gets an "Object reference not set to an instance of an object" exception. I discover (or get a bug report of) something new like this about every week or two. I've had enough, and was thinking of trying some sort of fuzz testing on the application to try to ferret out undiscovered issues. If I roll-my-own fuzz testing, I'd assume I at least need to be able to generate test harnesses that run pieces of my app (main window, FormX, FormY, FormZ, ...) independently and try to inject events into them. I was trying to look for tools suited for this, but so far have come up with nothing for Win Forms. (There seems to be no shortage of fuzz testing tools for web apps, however). Any helpful ideas?

  • Problems with maven output directory

    - by Gandalf StormCrow
    I'm using almost same POM for both my projects, they are on the same workspace but they are not related at all, they are related however because in both I use spring and jboss. Here is the pom : <project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd"> <modelVersion>4.0.0</modelVersion> <groupId>com.springinaction.hello</groupId> <artifactId>spring-in-action</artifactId> <packaging>jar</packaging> <version>0.0.1-SNAPSHOT</version> <name>spring-in-action</name> <url>http://maven.apache.org</url> <properties> <jboss.ome>C:\jboss-5.1.0.GA\server\default\deploy</jboss.ome> <springversion>2.5.3</springversion> </properties> <dependencies> <dependency> <groupId>org.springframework</groupId> <artifactId>spring</artifactId> <version>${springversion}</version> </dependency> <dependency> <groupId>log4j</groupId> <artifactId>log4j</artifactId> <version>1.2.14</version> <scope>provided</scope> </dependency> </dependencies> <build> <plugins> <plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-war-plugin</artifactId> <version>2.0</version> <configuration> <warName>spring-book</warName> <outputDirectory>${jboss.ome}</outputDirectory> </configuration> </plugin> </plugins> </build> </project> What I want to achieve with this POM is that I want to name my war when built spring-book.war and copy it to Jboss location I specified. Now in my first project this works it does exactly what I requested but in other it does not. I changed springversion and jboss home properties variable but everything remains the same, what can I do ? The project builds and all, everything is working perfectly just I don't want to copy everytime in my jboss dir and previously remove the old war, it takes about 20sec on each source code change its a lot

  • What .NET reporting tools are best for dynamic report generation?

    - by bvanderw
    Perhaps I need to define "dynamic generation". By this I mean using graphics primitives to draw on the page (such as DrawText or DrawLine, etc) This is what System.Drawing.Printing provides. I often need to create forms and reports for Windows applications that either require dynamic generation or where I need control over the formatting that stretches or goes beyond the capabilities of most report designers. Essentially, I need to ability to create my own pages using graphics primitives like you can do with System.Drawing.Printing that are part of package that also provides a report designer, exporting to PDF, etc. In my Delphi days, I used Rave Reports (along with the exporting add-ons from Gnostice) because it was the only Delphi reporting tool that gave you that kind of fine control. I've been struggling with the reporting tools provided by Developer Express and I have given up trying to make them do what I need to do. I downloaded a trial of ActiveReports and was able to completely create one of my dynamic reports (using their Page class) in a few hours one afternoon. It's likely I will buy their product, but it's a bit frustrating to have to do so after investing in the Developer Express tools. Before I do so, are there any other products that offer this functionality that I should investigate? As far as I can tell, Crystal Reports does not - is this correct? Thanks.... --Bruce

  • Fast sketching tools for drawing C/C++ structs, pointers, etc...

    - by tomasorti
    Hi. I would like to know what do you use to sketch relations between different entities in C/C++. This can be a very broad issue, so I'll try to clarify a bit more my question and give an example. I'm looking for something that is simple enough as a user, and let me sketch easily containers, pointers, etc... in an informal way. The aim is to document some structs relations to pass them to junior developers. A look at the drawings is supposed to accelerate the understanding of the code. My solutions at this moment are to use: 1) Paper & pencil. 2) Microsoft PowerPoint/Word Autoshapes. 3) Freeware Dia. Other ones could be: 4) Microsoft Visio, but my company does not own licenses. 5) UML tools. I don't want to go this way. This is what I mean a more formal solution. I know tools like Rational Rose are great, and I tried boUML and violet and they are fine in some parts, but I prefer the flexibility of options 2) or 3). Finally, let me write down a more concrete example: Let's say I what to sketch a map that contains another map as the mapped value, and that one contains a struct as the mapped value, that holds a vector of pointers of a type and a pointer to other type. Also, there exist other structs that hold pointers to the objects pointed by the previous map, so there are objects pointed from different places. This is just one example I have, but you can easily come with one from you experience. What would you use to sketch this example or another similar you have dealt with? Best regards, Tomas.

  • What tools do you have at your disposal as a manager to promote a way of thinking

    - by John Leidegren
    This question goes beoynd just programming, but I'd like to get some input on this, if that's okay with the community. Preferably from people that do a lot of coding themselves but also manage other people coding. My problem is this. We have all these ideas that we know is good for the overall strategy of the company and the problem is not figuring out what to do, it's to come about this change. Just telling someone to do things differently isn't enough and it's hard to promote a mind set that is shared within all of the company, (this will take time). If I could jump forward I'd like it if we could create a very nurturing company culture that promotes these ideals cross all areas but I'm not sure what tools to use. And by tools I mean anything I'm legally permitted to do. e.g. we could talk about, we could arrange traning sessions, we could spend more time in meeting (talk about it more), we could spend more time designing, we could spend more time pair-programming, we could add/remove incentive or we could encurage more play. Ultimately if we did all of these things what will be the recurring theme that ties this together. I'd like to be able to answer the question -- why should we do things like this? -- and come up with an answer that explains how important it is to think about our ideals from begining to end. I've puposly avoided to talk about or specifics of the situtation becuase I believe that it narrows things down too much. But I guess, by know you either know how to answer this question or you're as confused as I am ;) I'd love to hear from people who had to bring about a change in order to go from chaos to order, or fix something in the organization which wasn't working. And I'd like to hear it from the perspective of the developer and designer. -- or -- You could simply weigh in on what are the most important qualities in an organization encurage or stimulate rigid fun development cycle from start to finish?

  • CherryPy sessions for same domain, different port

    - by detly
    Consider the script below. It will launch two subprocesses, each one a CherryPy app (hit Ctrl+C or whatever the KeyboardInterrupt combo is on your system to end them both). If you run it with CP 3.0 (taking care to change the 3.0/3.1 specific lines in "StartServer"), then visit: http://localhost:15002/ ...you see an empty dict. Then visit: http://localhost:15002/set?val=10 http://localhost:15002/ ...and you see the newly populated dict. Then visit: http://localhost:15012/ ...and go back to http://localhost:15002/ ...and nothing has changed. If you try the same thing with CP 3.1 (remember the lines in "StartServer"!), when you get to the last step, the dict is now empty. This happens in Windows and Debian, Python 2.5 and 2.6. You can try all sorts of things: changing to file storage, separating the storage paths... the only difference it makes is that the sessions might get merged instead of erased. I've read another post about this as well, and there's a suggestion there to put the session tools config keys in the app config rather than the global config, but I don't think that's relevant to this usage where the apps run independently. What do I do to get independent CherryPy applications to NOT interfere with each other? Note: I originally asked this on the CherryPy mailing list but haven't had a response yet so I'm trying here. I hope that's okay. import os, os.path, socket, sys import subprocess import cgi import cherrypy HTTP_PORT = 15002 HTTP_HOST = "127.0.0.1" site1conf = { 'global' : { 'server.socket_host' : HTTP_HOST, 'server.socket_port' : HTTP_PORT, 'tools.sessions.on' : True, # 'tools.sessions.storage_type': 'file', # 'tools.sessions.storage_path': '1', # 'tools.sessions.storage_path': '.', 'tools.sessions.timeout' : 1440}} site2conf = { 'global' : { 'server.socket_host' : HTTP_HOST, 'server.socket_port' : HTTP_PORT + 10, 'tools.sessions.on' : True, # 'tools.sessions.storage_type': 'file', # 'tools.sessions.storage_path': '2', # 'tools.sessions.storage_path': '.', 'tools.sessions.timeout' : 1440}} class Home(object) : def __init__(self, key): self.key = key @cherrypy.expose def index(self): return """\ <html> <body>Session: <br>%s </body> </html> """ % cgi.escape(str(dict(cherrypy.session))) @cherrypy.expose def set(self, val): cherrypy.session[self.key.upper()] = val return """\ <html> <body>Set %s to %s</body> </html>""" % (cgi.escape(self.key), cgi.escape(val)) def StartServer(conf, key): cherrypy.config.update(conf) print 'Starting server (%s)' % key cherrypy.tree.mount(Home(key), '/', {}) # Start the web server. #### 3.0 # cherrypy.server.quickstart() # cherrypy.engine.start() #### #### 3.1 cherrypy.engine.start() cherrypy.engine.block() #### def Main(): # Start first webserver proc1 = subprocess.Popen( [sys.executable, os.path.abspath(__file__), "1"]) proc2 = subprocess.Popen( [sys.executable, os.path.abspath(__file__), "2"]) proc1.wait() proc2.wait() if __name__ == "__main__": print sys.argv if len(sys.argv) == 1: # Master process Main() elif(int(sys.argv[1]) == 1): StartServer(site1conf, 'magic') elif(int(sys.argv[1]) == 2): StartServer(site2conf, 'science') else: sys.exit(1)

  • Can I tweak a page's appearance using Google Chrome's developer tools?

    - by Nathan Long
    When I'm working on a web page layout, I often use Firefox and Firebug to tweak the CSS until it looks right, then modify my style sheet to match. Right now, I'm trying to fix something that looks fine in other browsers but wrong in Google Chrome. I have pulled up Chrome's Developer Tools, and can inspect the computed style, but don't see a way to edit values and see the results on my page. Is there a way to do this?

  • Can MKS Integrity integrate with other source control tools? (SVN, Git...)

    - by bnsmith
    My boss is interested in using MKS Integrity for bug tracking, feature requests, Wiki documentation and so on. However, we currently use Subversion, and he doesn't want to force us devs to use a version control system that we don't like. Is is possible to integrate a different version control program into MKS Integrity? I'm particularly interested in SVN, Git, Mercurial and Bazaar. If you've tried mixing tools like this before, I'd love to hear about your experiences.

  • What call from the Android Development Tools API should I use to poll project target loading?

    - by Ricardo Gladwell
    I'm writing my own eclipse plug-in that integrates with the Eclipse Android Development Tools (ADT). However, I'm getting a CoreException ("Project target not loaded yet.") thrown when I attempt to call IProject.build on an Android project as part of a unit test: IProject project = importProject(...); project.build(IncrementalProjectBuilder.FULL_BUILD, monitor); Should I be waiting for the project target to load before calling the above? If so, what call should I use to poll the project target loading status?

  • Are there any tools for performing static analysis of Scala code?

    - by Roman Kagan
    Are there any tools for performing static analysis of Scala code, similar to FindBugs and PMD for Java or Splint for C/C++? I know that FindBugs works on the bytecode produced by compiling Java, so I'm curious as to how it would work on Scala. Google searches (as of 27 October 2009) reveal very little. Google searches (as of 01 February 2010) reveal this question.

  • If I write an algorithm to encrypt a file, are their tools available to break the encryption?

    - by Andrew
    I have an idea for encryption that I could program fairly easily to encrypt some local text file. Given that my approach is novel, and does not use any of the industry standard encryption techniques, would I be able to test the strength of my encryption using 'cracker' apps or suchlike? Or do all those tools rely on advanced knowledge of the encryption process (or intercepted 'keys'), meaning I'd have to build my own cracker for testing?

  • What other libraries or tools would you add to a Spring/Hibernate stack for improved rapid applicati

    - by CaptainAwesomePants
    My team at work maintains a fairly large webapp written on top of Spring and Hibernate. We're about to start making some fairly large scale changes to the site, and we're enamored with the rapid application development speeds allowed by some other frameworks, like Rails. We haven't really changed our stack much in the last year or two, and I'm wondering what new tools, approaches, and libraries might be out there to help speed up webapp development.

  • What free tools or strategies can help debug a multi-threading corruption bug?

    - by WilliamKF
    I have a client server application with multi-threading. The server side is failing with a std::list getting corrupted resulting in a SEGV. I suspect that there is some kind of cross thread timing issue going on where the two threads are updating the std::list at the same time and causing it to be corrupted. Please suggest free tools to track this down or strategies that might be helpful.

  • How easy is it to write a Flash app and what tools are needed?

    - by J Lynch
    I have been wanting to learn to write a Flash app so that it can be embedded inside a webpage. But is it hard to write one, say, just to show a circle bouncing around the walls of the 4 sides of the Flash window (no gravity, but just like the dot in the game "Pong"), and what tools are needed (and are they free?). Thanks very much.

  • What tools to use to build large java commercial projects ?

    - by openCage
    There are several tools to build java projects: ant mvn ivy buildr ... From my experience Ant is great for small projects and projects with special build requirements. Mvn is great for large but typical projects without too much special requirements. It also seams better for open source than for commercial projects. What would you recommend in case of large, enterprise, commercial projects ? What do you currently use and what would you rather use and why ?
