  • Elf: Dump symbol value in BSS, DATA or RODATA?

    - by noloader
    I have a ELF shared object with a symbol initialized to a value. I want to know what the value of a symbol is. I know objdump -T will give me the symbol's address and length but I need the value: $ arm-linux-androideabi-objdump -T libcrypto.so.1.0.0 | grep -i FIPS_signature 001a9668 g DO .bss 00000014 FIPS_signature However, hexdump knows nothing about ELF sections, offsets and virtual addresses, so I can't use the information: $ hexdump -v -x -n 0x14 -s 0x001a9668 libcrypto.so.1.0.0 $ How do I dump the value of the symbol?

  • Array split by range?

    - by acidzombie24
    I have an array, i don't know the length but i do know it will be =48bytes. The first 48bytes are the header and i need to split the header into two. Whats the easiest way? I am hoping something as simple as header.split(32); would work ([0] is 32 bytes [1] being 16 assuming header is an array of 48bytes) using .NET

  • How is "Make Object ID" implemented in the .NET debugger?

    - by Omer Raviv
    Hi, I would like know how this feature is implemented in VS - I understand it holds some sort of weak-reference to the object in the debugged-application's memory, but how exactly is it accomplished? I know simply tracking the address (as in native code) wouldn't work, because the GC might move the object about, invalidating the address. Thanks.

  • Detecting position with drag-and-drop and jQuery?

    - by Matthew Westrik
    Hi, I need to know how to detect the position of a dragged item as opposed to other divs. I need to detect whether an item is dropped outside of two different divs. (I am building a mac dock type start page and I need to know how to do this so I can delete icons by dragging them off the bar.) Any help would be greatly appreciated.

  • Deploying a Django application in a virtual Ubuntu Server

    - by mfsaint
    I have a virtualbox machine running Ubuntu Server 10.04LTS. My intention is to this machine to work like a VPS, this way I can learn and prepare for when I get a VPS service. Apache+mod_wsgi for deploying the Django app seems the right choice to me. I have the domain (marianofalcon.com.ar) but nothing else, no DNS. The problem is that I'm pretty lost with all the deployment stuff. I know how to configure mod_wsgi(with the django.wsgi file) and apache(creating a VirtualHost). Something is missing and I don't know what it is. I think that I lack networking skills ant that's the big problem. Trying to host the app on a virtualbox adds some difficulty because I don't know well what IP to use. This is what I've got: file placed at: /etc/apache2/sites-available: NameVirtualHost *:80 <VirtualHost *:80> ServerAdmin [email protected] ServerName www.my-domain.com ServerAlias my-domain.com Alias /media /path/to/my/project/media DocumentRoot /path/to/my/project WSGIScriptAlias / /path/to/your/project/apache/django.wsgi ErrorLog /var/log/apache2/error.log LogLevel warn CustomLog /var/log/apache2/access.log combined </VirtualHost> django.wsgi file: import os, sys wsgi_dir = os.path.abspath(os.path.dirname(__file__)) project_dir = os.path.dirname(wsgi_dir) sys.path.append(project_dir) project_settings = os.path.join(project_dir,'settings') os.environ['DJANGO_SETTINGS_MODULE'] = 'myproject.settings' import django.core.handlers.wsgi application = django.core.handlers.wsgi.WSGIHandler()

  • Does my Oracle DBA need root access?

    - by Dr I
    I'm currently discussing with my Oracle DBA Collegue that request a root access on our production servers. I'm not so hot to let him use the root access on our production servers. He is arguing that he need it to perform some operations like restarting the server and some other obscure arguments. The point is that I'm not agree with him because I've set him a Oracle user/group and a dba group where Oracle user belong. Everything is running smoothy and without any root permissions for now. I also think that all administrative tasks like scheduled server restart and so one need to be operated by the proper administrator (The Systems administrator on our case) to avoid any kind of issues related to a misunderstanding of the infrastructure interactions. So, I need the help of both, sysadmins and Oracle DBAs to lead me on the correct direction. If my collegue really need this rights I'll give him, but I'm just basically quite affraid of that because of security and integrity concerns. I know that my collegue is really good as a Oracle DBA and he know is work very well, but I also know that I've very few cases where a software and its admin really need root access. Once again, I'm not looking for pros/cons but rather an advice on the way that I should take to deal with this situation.

  • Is there something like clock() that works better for parallel code?

    - by Jared P
    So I know that clock() measures clock cycles, and thus isn't very good for measuring time, and I know there are functions like omp_get_wtime() for getting the wall time, but it is frustrating for me that the wall time varies so much, and was wondering if there was some way to measure distinct clock cycles (only one cycle even if more than one thread executed in it). It has to be something relatively simple/native. Thanks

  • Why is dwm.exe using so much memory?

    - by Leonard Challis
    I've scoured the web, but I'm sick of reading "scan your computer for viruses" and "upgrade your RAM" on answers to similar questions to this. I understand that dwm.exe is for (simply put) caching bitmaps for things like Aero-peek and similar, but as far as I have read it shouldn't be using vast amounts of memory. My colleague and I both have 4GB of RAM, Core 2 Duo, blah, blah -- essentially they're pretty capable. His dwm.exe is running at around 30mb, mind is currently running at about half a gig, though it does fluctuate quite a lot. This is the same while running the exact same applications (currently Zend studio, FireFox (with firemin - low memory usage), Outlook). Every so often I will get a notification asking me if I want to switch to Aero Basic because it's using too much memory, and sometimes it will just switch itself to basic and let me know why. I know it's possible to stop it switching, but I want to know why it is using too much memory otherwise it's just papering over the cracks. One thing to add is this seems to have started after a robbery on Monday, where two of my monitors were stolen, and I had to temporarily use a couple of alternative monitors. I am now using brand new monitors but the problem is the same. All drivers installed and working seemingly fine. Any ideas why the usage is so high? We are using windows 7 64-bit Professional.

  • Advice: USB Monitoring Programming

    - by Kashif
    I need an advice about USB programming in linux. i have to design a USB monitoring program that 'll keep checking usb ports of a linux cent os. as soon as a usb or external hard disk is connected, this program will shoot an email to some specific person about detail of usb (as size, mount on, time). when usb is disconnected, it will again shoot an email to some person with same kind of information. mean while this program will also write logs in syslog/messages with name of programing for easy tracking. Now I want ask that what is best way to develop this program. as I'm new to this field so i know nothing about it? either i should use perl, bash scripting or some other language? I have no idea what is right way to adopt coz this program will keep running all the time to keep a check on usb ports. I know few commands in like lsusb, fdisk (to check attached usb) and df -h (to get detail of usb) but dont know how i can achieve using these commands that i am thinking. also one more thing that in future i also need to modify this program for ubuntu and Citrix XenServer and it should be same everywhere.

  • Instructions to setup primary and only domain controller

    - by Robert Koritnik
    Where could I get best step by step instructions (with some simple explanations) how to setup domain controller on Windows Server 2008 R2 Server Core? I don't know what do I need? Do I need DNS as well and AD and so on and so forth. I don't know enough about these things, but I need to set them up to prepare development environment. I would also like to know how to configure firewall on DC machine, to make it visible on other machines because I've setup DC somehow but I can't connect to it... This is my HW config: Linksys internet router with DHCP my dev machine is Windows 7 my DC machine is a VM in my dev machine my dev machine has a hw network adapter to linksys and a virtual network adapter to DC DC machine has two network adapters: one to linksys (to be internet connected so it can be updated etc.) and one to host (my dev Win7 machine) Edit My development machine should access domain controller and logon using domain credentials. Development machine would access internet directly via Linksys router. My domain controller machine would only serve authentication (and if I'm able to configure it right) should also have Active Directory Federation Services in a workable condition. I hope this is a bit more clear now. At least a small bit.

  • Can GPL interface with MIT library

    - by dmontain
    I inherited a GPL project which I'm trying to improve. I know of an MIT library that could really help me improve this project. I know its developer personally and I read his blog, and he's made it clear on several occasions that he likes MIT and Apache licenses. My questions: Do I have to tell him that I'm using his library in a GPL project? Is it ok for my GPL project to interface with his MIT library?

  • What is the state of C99 support in major compilers / toolchains?

    - by pkh
    A response to a comment I made here made me stop and think: "I don't really know what the state of C99 support is." Wikipedia gives details for a few compilers, but I'm not familiar enough with C99 to know all the bits and pieces of the standard, so I'm looking for a gestalt overview answer to the question: What is the state of C99 support in major compilers / toolchains?
