General :: Upgrade 32 Bits Programs To 64 Bits On Opensuse 11.2
Jan 5, 2010I'm quite new to linux and I recently (and courageously) upgraded the computer of my work from opensuse 11.0 32bits to opensuse 11.2 64bits.
Well, everything would be quite fine except that I still have some softwares 32 bits that have the 64 bits version available. I know that because, using YaST, I can see by the Installed software section that there are 'choices' of versions for some programs; these versions are 'i586' and 'x86_64', and many of them have the i586 version installed.
So, I wonder if there is some type of auto upgrade all programs which are i586 and have the matching x86_64 avaliable...

Jul 20, 2010I have a big file full of records like this
1, 2, 4, 5, 6
1, 3, 5, 6, 3
1, 4, 5, 6, 6
2, 4, 5, 5, 5
2, 3, 4, 5, 2
anyway i need to take the average of all rows with the same 1st number(key). i.e.
1, 3, 4.66, 5.66, 5
2, 3.5, 4.5, 5, 3.5
I know this is something awk/sed would be great for, i just dont have enough experience with them to accomplish it, Also, what about averaging those columns together? so, after I output this to a file, id like to get another like:
1, 4.58
1, 4.125
The number of colums to add might not always be 4 either. EDIT: this might be easier to do in gnuplot, so I mainly just need an answer to the first part.

Programming :: Echo Hello Command Does Not Return
Jan 11, 2010I am testing the serial ports on a Single Board Computer(SBC) running Linux kernel 2.6.29. I usually do this by connecting the serial port to another PC serial port, then doing "cat /dev/ttyS0" on PC and "echo hello > /dev/ttyS0" on the SBC. However in the current system, "echo hello > /dev/ttyS0" command does not return at all! Also no characters appear on the destination port. I am running the echo command as root. The system boot messages show that the serial port in indeed /dev/ttyS0.

Does anyone have any ideas as to what the problem called be, or a better method of being able to read from two different endpoints?
