I'm running a java program and to debug the program instead of using a debugger I would like to look to the heap and to the bytes in the memory of the process. I was hoping that the pointers would give me a snapshot of a moment of the application. It exists a program that allow us to look to the details of a process and to the memory ram?
View 2 RepliesA friend of mine asked me to try and recover some photos she deleted by accident on her SD memory card. Normally, I would flip over to my Windows box and do this, but I'm wondering if there is a Linux equivalent to a Windows data recovery program. I'm running Fedora 10.
View 2 Replies View RelatedDoes there exist a program for Linux that can display raw binary data?
Each byte in my binary files represent a pixel, so it would be very useful if something like this exists where I could say
program_name --input=dat001.bin --width=200 --height=100
and it would display the pixels.
Are there any tools to view/edit user space memory of running processes on Linux?
It would be a great learning tool.
For Linux command sort, how do I force sort to load all input into memory and sort assuming I have enough memory? Or is it best to use a RAMDISK to store the input before feeding it to sort?

The problem is that in the old one i had linux (Slackware) and so it doesn't allow me to view the content of the folder /home/myself. If there was something possible to do to recover all the data or if it will be forever lost.

View 6 Replies View RelatedI wrote a program that multiplies 2 matrices using multi-threads and another one using multiple processes and shared memory. Both in C.I need to find the total memory usage of these programs. I know of the top command, but when my matrices are relatively small they don't even show up on top because they complete so fast, how can I find the memory usage for these instances?Also, how can I find the total turnaround time of my programs?

I Just got the ADS VideoXpress video capture USB thing (Plug composite video and audio into it, and plug it into a computers USB port). Anyway, I've tried to install what came on the CD, with Wine, but still cant view any video. I don't need it to record from it, I just want to view the video live as it passes through. I don't even need audio, just the basic low quality video.

I am a total noob when it comes to opensuse. I just read the reviews and comments from forums taht's why I wanna try this alternative. I have 1 physical drive that has two partitions. 1 is dedicated for my windows OS (20 GB) and the other for my data (approx. 100GB).
How can I install opensuse 11.3 to just 1 partition (20GB) and leave my data partition (approx. 100GB) as it is? Can I still view/access/read the files from my data partition after I have successfully install opensuse 11.3 to my Os partition?
I have it installed on a HP mini 1010NR It worked great once I got help to figure out how to make my wifi work.

So I tried Kopete and like it but cant get the webcam to work every thing works just fine I cant send invites and cant receive images. At first I was getting an error message telling me to go to a nonexistent site for help. Now it just tells me No "webcam image received" and just strait up does not send invites. I am trying to get this to work or be directed to a better program that meets my needs and how to set it up.
View 2 Replies View RelatedI have a simple C program that reads a 1 GB file from disk into memory.The first time I run this program, the process takes several seconds. But if I run this program again immediately after it finishes, the read happens almost instantly. What is going on here?My suspicion is that the operating system is realizing that the data I'm trying to read is still uncorrupted in memory (its been freed but not overwritten), so instead of reading it again, it just gives me the same block. I would really like to know what this process is called, or any Googleable keywords that would allow me to research it.
The reason I ask is because the size of my input data has increased. Now I need to read in a 6 GB file (my system has 12 GB of RAM), but I'm not observing the same behavior with the larger file. Each time I run the program the read takes an equally long time.
I am using ARM9(S3C2440) board in which linux kernel 2.6.30.4 is ported and i need to write some 8-bit data(say 0xAA) into the memory location 0x08000000 and i need to trace the data written into the location is correct or not how to do this in linux.
View 3 Replies View RelatedI have a mxn matric (which is my simplified way of saying it is RAM with bytes on it) Some of the locations on this metric is filled with some data and some places are empty. The mxn are very big numbers in size. I am trying to make a program so that if a system call wants to write some thing on empty locations on this mxn metric it should be able to do so without any problem. The thing which I want to understand or logic of a data structure is what data structure do you people feel should I be maintaining so that I can allocate the requested space immediately from the above mxn matric when some system call requests for some (k) number of locations from above metrics.
The logic initially I thought was to maintain a hashtable
1bytes requested----------> location 1,location 2,location 3.........location n
2bytes requested----------> location 1,location 2,location 3.........location n
3bytes requested----------> location 1,location 2,location 3.........location n
[code]....
but the problem with above logic is size of the pointers where I will be writing this problem is unsigned 64 byte.So to know location of one free byte if I am maintaining one pointer of type u64 this is not a feasible solution.

I went to an interview last week and there was this guy who asked a simple question that i have been trying to solve for a couple of days. I tried google but i just cant get the search keywords right. The result were just useless. Well, the question is : "How can we allocate a limited memory to a process before we start its execution" well, the question is related to an X11 system so may be some flags must be set to limit its memory.

View 3 Replies View RelatedA few years back when I was running Linux most of the time I used a program that gave me information on my machine.
It had different themes and such, and it would usually rest vertically along the side of the desktop. It would tell one information on drives, space, memory, I think you could even have it tell you the weather if you entered geographical information.
I know I'm being a bit vague but that's all I can remember, does anyone recall this program? It was pretty popular back then...so I wonder if it's still under development.
I am trying to run C++ program on linux.
My program consume a lot of memory so that the memory is used up fast and memory swap is very high.
