hello
I am working on a simple combinatorics part, and found that I need to recover position of two bits given position of other two bits in 4-bits srring.
for example, (0,1) maps to (2,3), (0,2) to (1,3), etc. for a total of six combinations.
My solution is to test bits using four nested ternary…

I'm stuck with what seems a bug in VmWare Player (build 203739). I'm using W7 Ultimate 64bits as host and have a CentOS 5.4 (64 bits) as a guest and a Windows XP Professional SP3 (32 bits) as another guest. From the 64 bits machines (the host and the linux guest) I cannot ping the windows XP.

I've recently installed Ubuntu 12.04 64-bit on a HP Envy 15 1104tx. Most stuff appears to be working fine with the exception of the two USB3 ports (USB2 port works fine). I've read a lot of articles but so far have not been able to find a solution.
I've tried adding 'pci=nomsi' to '/etc/default/grub'…

I have a buffer of bits with 8 bits of data followed by 1 parity bit. This pattern repeats itself. The buffer is currently stored as an array of octets.
Example (p are parity bits):
0001 0001 p000 0100 0p00 0001 00p01 1100 ...
should become
0001 0001 0000 1000 0000 0100 0111 00 ...
Basically…

I typically run across gurus at SO and other places (instructors, book authors etc.) that would say something along the lines "This will cause alignment issues" or other low level tidbits.
I want to learn about all these tidbits that are relevant to programming. Now usually when I see low level…

I'm always interested in learning the inner working of things. I started with C programming and then learnt Operating systems (from stallings) and then linkers & loaders and then assembly language after reading these now I want to go into little more depth.
Computer Architecture. I feel that…

When teaching recently about the Big vs. Little Endian battle, a student asked whether it had been settled, and I realized I didn't know. Looking at the Wikipedia article, it seems that the most popular current OS/architecture pairs use Little Endian but that Internet Protocol specifies Big Endian…
