After reading E-myth Revisited, I realize that I can do a better job at making my company less reliant upon me... I spend a tremendous amount of time answering silly questions (silly to me, but necessary for my developers to get the job done). I need to write a set of operating manuals for what to do in certain situations... For insta...

If you need more details don't hesitate to...
I do not work with Silverlight personally. However, I still keep an eye out on it. Silverlight 3 and the upcoming 4 has many features that seems would make it a nice web-based operating platform like out-of-browser capacities, printing support, speed, deep-zoom, multi-touch, many controls and many more. I am wondering if you think it can...

I want to develop a simple operating system. One that asks user to login by entering username and password. Once logged in the user sees their desktop and can create some text files. I don't have any prior experience of OS development. I know C and C++ and Java. I don't know where to start. I want to use the Linux kernel, but I don't k...
I don't understand why the ABI is important context of developing user-space applications. Is the set of system calls for an operating system considered an ABI? But if so then aren't all the complexities regarding system calls encapsulated within standard libraries? So then is ABI compatibility only relevant for running statically link...
Hi there, I just made some changes to the context switch routine of Linux. I am facing now the following dilemma: The context switching time is no longer deterministic, i.e. the execution time varies on the applications that are switched out. I am wondering now what could be the negative implactions of such a behaviour. One potential pi...
I am writing a program that simulates process synchronization. I am trying to implement the fork and semaphore techniques in C++, but am having trouble starting off. Do I just create a process and send it to fork from the very beginning? Is the program just going to be one infinite loop that goes back and forth between parent/child pr...

Hello, In a typical C program, the linux kernel provides 84K - ~100K of memory. How does the kernel allocate more memory for the stack when the process uses the given memory. IMO when the process takes up all the memory of the stack and now uses the next contiguous memory, ideally it should page fault and then the kernel handles the p...

Hey everyone, I attended this year's HostingCon in Austin, TX, and found a really interesting operating system being advertised there called CloudLinux (www.cloudlinux.com). It seems like a hosting company's dream come true for the reliability benefits it would bring to a shared hosting environment and I'm wondering if any of your ow...
