What is your position on Microsoft's contribution of 20klines of code to the Linux Kernel and 3 Linux drivers?
Q. As Microsoft begins its slow migration to the integration of open-source software into it's system, amazing things have happened. Most recently, Microsoft released 20,000 lines of code as a contribution to the linux Kernel which include 3 linux-based device drivers, all in the hopes of enabling Linux/Unix distros to be virtualized into programs such as Hyper-V for cross platform integration. What is your opinion on this? Do you like it or not, and why?

A. These are disturbing days for the open source community. Microsoft are admittedly playing by the open source code at present but how long will it last before the court cases begin. This only goes to prove that Microsoft do indeed see Linux as a threat particularly when it comes to Server installations The Perfect Server - Ubuntu Hardy Heron (Ubuntu 8.04 LTS Server) Also this may be the start of the evidence of the damage caused by the Novell deal with the devil from which I am still smarting.

Is there an efficient way to deconvolve a gaussian blur kernel to recover the underlying data?
Q. I have a regular 2D grid of points that have been blurred by a Gaussian kernel and then sampled using an irregular grid. Is there an efficient algorithm for deconvolving the kernel to recover an approximation to the underlying data?

A. One simple method is to take the fourier transform of the blurred image and the kernel. No divide transform of image by transform of kernel. In spatial domain this can be done by convolving the blurred image by the inverse of the kernel matrix. But from textbooks on image processing, it becomes evident, that even if one has the actual kernel that was used to blurr the original image, it is difficult to reverse the process exactly. Moving on to a bit more advanced level, one can apply Minimum Mean Square Error filtering also known as Wiener Filtering. Disadvantage with the simple method shown above is that it does not always compensate for the noise produced in the image. This is were Wiener filter provides better results. It is based on… [cont.]

How to get child pids from parent pid in linux kernel mode?
Q. hi , i need C code to get child pids from its parent pid in linux and in kernel mode, is there anything like getpid() or getppid() which works in kernel mode? can you suggest ant trick how to do this. thanks

A. fork() returns an int, the return value (from the parent process) is the pid of the child. From the child process the return value is 0. For example int pid = fork(); if(pid==0){ printf("I am the child process."); } else{ printf("I am the parent and my child is %d", pid); }
