• problem in allocating kernal memory by kmalloc() from user space ?

  - by sagar

  Is there any protection provided by kernel? Because when we tried to allocate memory using an kmalloc() from user space, the kernel allowed to allocated around 124 MB of memory, and when we try to write into it, the kernel crashed. If there was protection of kernel memory area, this wouldn't have happened, i guess

• continously add picture to video

  - by m.sr

  Every x minutes I grab an image from a network-cam. Now i want to add this picture to an existing video file - on the fly. I don't want to keep numerous image files and then encode them once in a while with e.g. mencoder mf://@${LIST} -mf type=jpg:fps=${FPS} ... The video format/codec doesn't really matter, as long as standard tools (mplayer, ffmpeg, vlc, ...) can handle it. Any ides or suggestions? Thanks in advance!

• Reading a variable messes it up?!?!

  - by EpsilonVector

  We have the following line of code: printf("%d\n", toc->runlist.next); printf("%d\n", toc->runlist.next); These are the definitions: typedef struct thread_overview_control{ int id[NR_UTHREADS]; list_t runlist; int active_counter; int main_thread; int need_resched; } thread_overview_control; thread_overview_control* toc; What I'm trying to do is implement user threads. For some reason the output of the above code at the point where our test run crushes is: 12345678 //some address 0 //NOW IT'S NULL?!?!?! How can this happen?? All we do is read a variable. And the strange thing is, without printf's there are no crashes. What's going on?

• find: missing argument to -exec

  - by Abs

  Hello all, I was helped out today with a command, but it doesn't seem to be working. This is the command: find /home/me/download/ -type f -name "*.rm" -exec ffmpeg -i {} -sameq {}.mp3 && rm {}\; The shell returns find: missing argument to `-exec' What I am basically trying to do is go through a directory recursively (if it has other directories) and run the ffmpeg command on the .rm file types and convert them to .mp3 file types. Once this is done, remove the .rm file that has just been converted. I appreciate any help on this.

• How to list library dependencies of a non-native binary?

  - by lvella

  When developing for native platform, I can use ldd to list all the shared libraries (.so files) a binary executable I build will try to load upon start-up. But when cross-compiling, I don't know how to get the same information. The ldd is not a normal binutils utility, like strip or ar, that can be built alongside gcc for cross compiling, but instead, it is a cryptic shell script that apparently can only run on native platform. So, using the cross-target binutils tools, is there any way to get a list of the dynamically linked dependency for of a foreign binary?

• htaccess rewrite; Should I change all relative links or not?

  - by Camran

  I have a rewrite in htaccess which makes this: domain.com/ad.php?ad_id=bmw_m3_328942948 into this: domain.com/ads/bmw_m3_328942948 Problem is the links which are relative to the file wont work... for instance if a link is pointing at '/bin/edit.php' like this originally: domain.com/bin/edit.php // WORKS but after the rewrite the link wants to point here instead: domain.com/ads/bin/edit.php // NOT WORK - NOTE THE /ads/ DOESN'T EXIST IN REALITY Do you understand my issue? What is done about this? Do I have to make ALL links using the newer rewritten format? .htaccess: Options +FollowSymLinks Options +Indexes RewriteEngine On RewriteCond %{REQUEST_URI} !^/ad\.php RewriteRule ^annons/(.*)$ ad.php?ad_id=$1 [NC,L] Thanks

• Why doesn't the Ubuntu Installer see all of my hard drives

  - by atodd

  I'm trying to setup a dual boot system with Windows Vista 64 (already installed) and Ubuntu 10.10. I added a new drive which is identical to the one Vista is installed on. When I boot into the LiveCD I can see and mount the second drive and edit it in Gparted. However, when I use the installer it will only bring up the drive that already has Vista installed. I've tried everything I know. I'm not sure if its a BIOS setting or something else I've missed.

• PyQt4.QtCore doesn't contain many of its classes and attributes

  - by toc777

  Hi everyone, I have built PyQt4 from source and everything went smoothly until I tried to use some of the classes and attributes located in QtCore. For some reason QtCore is missing a lot of functionality and data that should be there. For example from PyQt4.QtCore import QT_VERSION_STR is an import error. There were no errors or warnings given when building the packages and I have also tried with the PyQt packages from yum but I have the same problem. Has anyone else encountered this problem before? Thanks.

• gcc compiled binaries w/different sizes?

  - by BillTorpey

  If the same code is built at different times w/gcc, the resulting binary will have different contents. OK, I'm not wild about that, but that's what it is. However, I've recently run into a situation where the same code, built with the same version of gcc, is generating a binary with a different size than a prior build (by about 1900 bytes). Does anyone have any idea what may be causing either of these situations? Is this some kind of ELF issue? Are there any tools out there (other than ldd) that can be used to dump contents of binaries to see what exactly is different? Thanks in advance.

• How to set up Node server for production on own machine?

  - by Matt Hintzke

  This must be a pretty basic thing to do, but I cannot find any good guide on how to do it on the internet. I only find how to set up a development environment for Node. I want to be able to forward my R-Pi's port 80 to my Node server, which I want to obviously listen on port 80. How can I close the native port 80 so that I can let me Node server listen on that port. Ultimately, I want to be able to access my pi from any remote location. I know how to set up a static IP and forward the port on my router, but now how do I allow Node into port 80?

  There is a requirement I got.

• How can I get cmake to find my boost installation

  - by BD at Rivenhill

  I have installed the most recent version of boost in /usr/local (with includes in /usr/local/boost and libraries in /usr/local/lib/boost) and I am now attempting to install Wt from source, but cmake (version 2.6) can't seem to find the boost installation. It tries to give helpful suggestions about setting BOOST_DIR and Boost_LIBRARYDIR, but I haven't been able to get it to work by tweaking these variables. The most recent error message that I get is that it can't find the libraries, but it seems to indicate that it is using "/usr/local/include" for the include path, which isn't correct (and I can't seem to fix it). Does anybody have a solution for this off the top of their head, or do I need to go mucking around inside cmake to figure it out?
