  • Java execution details in System.out

    - by John
    As I remember there is a magic command line option in Java that turn on writing of operations that are currently executed to console. The output was looked like byte code. I do not mean -verbose, because it prints only class loading, while this option outputs information like memory allocation etc.

  • Operations on 64bit words in 32bit system

    - by Vilo
    I'm new here same as I'm new with assembly. I hope that you can help me to start. I'm using 32bit (i686) Ubuntu to make programs in assembly, using gcc compiler. I know that general-purpose-registers are 32bit (4 bytes) max, but what when I have to operate on 64 bit numbers? Intel's instruction says that higher bits are stored in %edx and lower in %eax Great... So how can I do something with this 2-registers number? I have to convert 64bit dec to bin, then save it to memory and show on the screen. How to make the 64bit quadword at start of the program in .data section?

  • Deploy Java application on MacOSX (from a Windows system)

    - by Matías
    Hello, Here's the deal. I'm just starting with Java programming, I've made a simple application that uses SWT graphic library and I want to deploy it on a Mac (running the latest version of MacOS X). I did all the programming in my Windows 7 machine, so here are my questions: Q1) Can I make an executable file for MacOS X from my Windows machine? How? (I saw that it's possible to create .exe files on Windows, instead of using .jar; I want to do the same for the Mac, of course it won't be an .exe) Q2) If I export my project in Eclipse and I choose Runnable JAR File and then on Library Handling I pick Extract required libraries into generated JAR or Package required libraries into generated JAR I end up with a huge .JAR (about 15MB of size, my application consist in just a button on a Window and a tiny method that doesn't do much). Is that considered normal? Here's the list of libraries that my project appears to be using: Thanks in advance.

  • Login system and sessions (php)

    - by Jonathan
    I've created a login page and registration page and now I want to use that to password protect pages and have pages which show information specific to that user. Would storing the user ID of the user logged in in a Session variable be a safe and correct way of doing this? How easy would it be for a user to change the session variable to a different ID and access another user's information, and not having to type the users login details in?

  • Establish SSH Connection Between Two Isolated Machines Using a 3rd System

    - by FurryHead
    I'd like to do the following with Python: Computer 1 starts SSH server (probably using twisted or paramiko) Computer 1 connects to Server 1 (idle connection) Computer 2 connects to Server 1 Server 1 forwards Computer 2's connection to Computer 1 (connection no longer idle) Computer 1 forwards Server 1's connection to listening SSH port (on computer 1) Result being Computer 2 now has a SSH session with Computer 1, almost as if Computer 2 had started a normal SSH session (but with Server 1's IP instead of Computer 1's) I need this because I can't port forward on Computer 1's network (the router doesn't support it).

  • Prompt message box Linux or any system from removable device

    - by Zloy Smiertniy
    Hi all, I have some files that in windows enable me to prompt messages when a device is plugged. In case it is lost it pops up a message that says the user to please return it to he owner. Does anybody know how can I do this in Linux? I doesnt need to be a complex thing, it can be an option in a right clic menu, or a splashcreen, or anything, just to make sure that the owner of the device may be looking for it.

  • Why can't my c++ program find the necessary .dll file?

    - by RemiX
    I am trying to use OpenCV (a computer vision library), which appearently uses a few .dll files, located in C:\OpenCV\bin (which has been added to the system PATH variable). However, if I try to run a simple test program, it gives a system error: "The program can't start because highgui.dll is missing from your computer. Try reinstalling the program to fix this problem." If I copy the highgui.dll file into the system32 folder, it works, but I don't want to have to put all the necessary .dll files in the system32 folder. Does anyone know why the .dll file can't be found or what I should do to fix it? (I already checked all paths in the PATH variable for validity.)

  • Using php to create a password system with chinese characters

    - by WillDonohoe
    Hi guys, I'm having an issue with validating chinese characters against other chinese characters, for example I'm creating a simple password script which gets data from a database, and gets the user input through get. The issue I'm having is for some reason, even though the characters look exactly the same when you echo them out, my if statement still thinks they are different. I have tried using the htmlentities() function to encode the characters, the password from the database encodes nicely, giving me a working '& #35441;' (I've put a space in it to stop it from converting to a chinese character!). The other user input value gives me a load of funny characters. The only thing which I believe must be breaking it, is it encodes in a different way and therefore the php thinks it's 2 completely different strings. Does anybody have any ideas? Thanks in advance, Will

  • Kill process started with System.Diagnostic.Process.Start("FileName")

    - by PedroC88
    Hello; I am trying to create an app that will perform actions on specific times (much like the Windows Task Scheduler). I am currently using Process.Start() to lunch the file (or exe) required by the task. I am initiating a process by calling a file (an .mp3) and the process starts WMP (since it is the default application), so far so good. Now I wan't to kill that process. I know that it is normal behavior for the Process.Start(string, string) to return nothing (null in C#) in this case. So I am asking how can i close WMP when I called it through Process.Start(string, string)?? Edit: Please note that I am not opening WMP directly with Process.Start() and this is the line with which I run the process: VB: Me._procs.Add(Process.Start(Me._procInfo)) C#: this._procs.Add(Process.Start(this._procInfo)) _procInfo is a ProcessStartInfo instance. _procInfo.FileName is "C:\route\myFile.mp3". That is why WMP opens. In any case, all of the Start() methods, except for the instance-one which returns a boolean, return nothing (null in C#), because WMP is not the process that was directly created (please note that WMP is run and the song does play).

  • ZF2 namespace and file system

    - by user1918648
    I have standard Application module in ZF2. It's configured by default, I didn't change anything. I just added some stuff: module/ Application/ src/ Application/ Entity/ Product/ **Product.php** Controller/ **IndexController.php** Product.php namespace Application\Entity; class Product { } IndexController.php namespace Application\Controller; use Zend\Mvc\Controller\AbstractActionController; use Zend\View\Model\ViewModel; use Application\Entity\Product; class IndexController extends AbstractActionController { public function indexAction() { $product = new Product(); } } and I get following error: Fatal error: Class 'Application\Entity\Product' not found in \module\Application\src\Application\Controller\IndexController.php on line 20 I use the same namespace, but it doesn't see it. Why? P.S: If I will change Product.php to be the following: namespace Application\Entity\Product; class Product { } then in the IndexController.php the following code will be working: namespace Application\Controller; use Zend\Mvc\Controller\AbstractActionController; use Zend\View\Model\ViewModel; use Application\Entity\Product\Product; class IndexController extends AbstractActionController { public function indexAction() { $product = new Product(); } }

  • How to convert from one co-ordinate system to another (graphics)

    - by Dororo
    I've been having issues with this for a little while now. I feel like I should know this but I can't for the life of me remember. How can I map the screen pixels to their respective 'graphical' x,y positions? The co-ordinate systems have been configured to start at the bottom left (0,0) and increase to the top-right. I want to be able to zoom, so I know that I need to configure the zoom distance into the answer. Screen |\ Some Quad | \--------|\Qx | \ Z | \ | \ \|Qy \ | Sx\ |Sy \| I want to know which pixels on my screen will have the quad on it. Obviously as Z decreases, the quad will occupy more of the screen, and as Z increases it will occupy less, but how exactly are these calculated? Thanks for any help.

  • Infrastructure for high transactional system (language & hosting suggestion help)

    - by RPS
    Some of our friends (University students) are trying to develop a twitter type application, I want to plan for at least 1000 transactions per second (I know it's wishful thinking) for initial launch. This involves several people connecting and getting updates and posting (text + images) to site. In the back end db will server the data and also calculates rankings of what to push to user based on complex algorithm on the fly real-time. Our group is familiar with Java and Tomcat/MySQL. We can also easily learn/code in PHP/MySQL. What is the best suited platform for our purpose ? Though Java seem to be easy to implement for us I am afraid that hosting will be a bit difficult. I could find cloud based php hosting services (like rackspace cloudsites) at reasonable cost. Amazon EC2 is a bit over our heads to manage on day-to-day. Also any recommendation on hosting ? (PHP or Java) We don't have millions in seed money but about $20K to start with. Any advice on above or any thing in general approach is much appreciated.

  • writing terminal output to file

    - by user1551817
    On my machine, I have some software which takes commands in the terminal and returns a list of values. To run it, I have to type something like: pdv -t filename I am trying to run it as part of a python programme. When I run the following: os.system('pdv -t %s' % (epoch_name)) then I get the values that I desire returned to my terminal (where epoch_name is the variable name for the filename). But when I try to write the result to a file: os.system('pdv -t %s % "(epoch_name)" > 123.txt') the file 123.txt is produced but it is empty. I know that I am misplacing the " and/or ' characters, but I can't figure out where they should go. Any help would be gratefully received!

  • Save GMail attachments directly to Google Drive

    - by Gopinath
    What makes Google Drive attractive is it ability to play nice with other Google offerings like Google Docs, GMail, Android mobiles & tablets. Google Drive is well integrated with Google Docs and every document you create is automatically saved on Google Drive. Google Drive’s integration with other services like GMail may be in progress at Google, but enthusiastic community developers has released a plugin to integrate with GMail. The Google Chrome plugin “Gmail Attachments To Drive” lets you automatically save GMail attachments to Google Drive with a single click. Once the plugin is installed it adds a link “Save To Drive” next to each attachment displayed on GMail and on clicking, it automatically saves the files to Google Drive. I tested the plugin by saving attachments like PDFs, MS Word documents and Images to Google Drive and it worked very well.  I don’t have any complaints on the plugin except couple of feature requests. If the plugin can provide option “Save All Files To Drive” it will be very much helpful to save all attachment of an email at one shot. Also it would be great if the developer can extend it to Firefox too. Anyways it’s a great plugin for Google Drive users and worth checking it out.

  • Differentiating between Hard and Soft Dependencies - Fedora Yum [closed]

    - by Sujit
    I will ask this with an example - I have installed gnash-plugin on fedora 64 bit with Yum. It pulled in following packages - Installing : agg-2.5-9.fc13.x86_64 1/6 Installing : gtkglext-libs-1.2.0-10.fc12.x86_64 2/6 Installing : boost-thread-1.44.0-7.fc14.x86_64 3/6 Installing : boost-date-time-1.44.0-7.fc14.x86_64 4/6 Installing : 1:gnash-0.8.8-4.fc14.x86_64 5/6 Installing : 1:gnash-plugin-0.8.8-4.fc14.x86_64 6/6 Now, I tested the plugin and I didn't like it. I want to remove all these above packages which got installed with the plugin as I don't longer going to need them. How can I do this? I checked remove-with-plugin for yum but it pulls in all the packages which are currently depending on the packages. I understand the thought process behind showing what packages are getting affected - but I am wondering if there is any way of looking at the history with what package got installed when I installed a certain package. When gnash-plugin wasn't there firefox was running fine with but after I installation firefox is now depends on this new plugin. Has any one worked on differentiating hard-dependencies(hard means the program will break if that package is not there) and soft-dependencies ( soft means the program may not get affected fatally) ?
