I'm running 9.1 and Firefox 3.5.7 with a few addons (better privacy, ghostery, cookieculler, adblock, personas) on a HP 8710p laptop with 4gb of ram.I use it to browse the internet at work, and I have it up for about 8-9 hours every day, during the course of the day I will open and close tons of tabs. At the end of the day when I'm getting ready to leave, I close out of firefox, and it takes one of my duo core processors all the way to 100% and sit at the top of my processes in my Conky for 5-10 minutes before it finally closes. I've been googling for a couple days and have yet to come up with anything,

View 6 Replies View RelatedI need show the number of process per user, and after the date of the oldest process per user also.
With "ps -eo user | sort -u" i get all users that are running any process. And with "ps U username | wc -l" i get the number of process that the user "username" is running.
But how can i merge both commands for do what i need? Like a FOR or something like that. There is any method of make a FOR using the list that i get with the first command?
And then for show the date of the oldest process.. with "ps U username | sort -k 4" (4 is TIME field) i can show the process of the user "username" sorting they by time. But how can i get the date of the process takes longer running?? I can get only the time, but no the date.
I want to calculate length of my array, say Unix here.
Code:
[linux1@HMLINUX1 abc]$ declare -a Unix=('Debian' 'Red Hat' 'Suse' 'Fedora');
[linux1@HMLINUX1 abc]$
[linux1@HMLINUX1 abc]$ echo ${#Unix[@]}
5
This should be ideally 4, but somehow it is showing as 5. However, when I am removing the space as RedHat instead of Red Hat, it is working perfectly.
Code:
[linux1@HMLINUX1 abc]$ declare -a Unix=('Debian' 'Redhat' 'Suse' 'Fedora');
[linux1@HMLINUX1 abc]$ echo ${#names[@]}

i've been using a awk script to calculate my data... i have 3 files:
file a1.txt:
2
3
4
[code]....
the results were (3.5, 6 and 3) which is pretty easy.. now i want to combine all this into 1 file and each have different columns and called it avg.txt which have something like this in the end:
3.5 6 3
i have a sorted file with many repeated lines like this:
1ujw
1ujw
1ul1
1us7

i need to calculated haw many times each line is repeated, for ex
1ujw 2
1ul1 1
1us7 5
etc.
I want to calculate log in bash script. I searched but could not find any bash command to directly do it. I am also thinking to send the variable in C program, calculate in C and get the answer back in bash script.But I think it is a long process. as I have to do this
i) gcc -o log log.c
ii) ./log > log_result.txt
iii) then read the result from log_result.txt

I'm using pyqt3 for my app and am lost on even how to attempt this task... On a vinyl cutter to have the blade pivot it must be offset from the center of the shaft it's on so say for example a .25mm offset would leave a .25mm unwanted vinyl attachment when the cutting is done. I somehow have to average or extrapolate that .25mm xy coordinate and add it to the hpgl plot file as a PUx,y; command? I have enclosed a simple sample file that has three images in it. In the corresponding hpgl file everything between the PU commands that are starting with PD are the code for that image (star for eg the pu to move to next image and then all PD for the next image and so on, so once the formula or procedure is figured out it can be applied to as many images there are in the file. Placing the new command at the head of each image PD group. Since there are absolute and relative cutters I enclosed the same exact plot for both types as the coordinates on relative can be negative numbers. Only PU and PD commands and a ";" as a command delimiter as sometimes many commands are on one line.The offset variable will come from a spinbox but .25 is good for an example.

Code:
// calculate BoardPos for index, where index is 0..80
void loadBoardPosFromIndex(BoardPos &pos, int index) {
pos.index = index;

This works on 9x9 boards, but I really dont get the math behind this, and how I can create a generic rule for both 6x6, 9x9 and 12x12 boards.

how to calculate (if possible) the end address of an image file in a flash memory. I'm trying to create a checksum and checkheader function and the info that I got is the file's offset, how many sector it consumes and its size.

I am trying to write a script to calculate the total amount of installed memory to use during an anaconda kickscript, so the swap file is created at 2 x the installed memory. I so far have the amount of installed RAM DIMMS but need a way to total them up and produce a varible I can use in the pre section of the install.
Code:
dmidecode -t 17 | grep Size | awk ' { print $2 }'
Output:
2048
2048
Note: on some servers there could be from 1 DIMM up to 16 DIMMS installed so the script needs to be able to handle this. I also can not use bc as it does not exist during the install stage. I am guessing I need a while loop to do this and use expr but do not know where to start for this logic.

Consider the following code:
Code:
int main()
{
int i=0;
pid_t pid;
for(i=0;i<2;i++)
[code]....
I get the following output:
Parent: chid_pid=4356 i=0 parent's pid=4355
This is child 4356 i=0
This is child 4357 i=1
[code]....
I can observe instead of two children(as I expect) processes there are three. This is because child process 4356 creates its own child. Why all the messages of the type "This is child X i=Y" are concentrated one under another? How exactly fork works? Is affected by the fact that I have a dual-core processor?
i want a process that can operate as both a TCP echo server and a UDP echo server. The process can provide service to many clients at the same time, but involves a single process that does not start up any other threads.
View 3 Replies View RelatedI am running Centos 5.3. I ran no updates, performed no installs, nor changed any configuration immediately prior to this issue. My problem is this: when I run the command startx (default runlevel 3), it is a long time (5-10 minutes) before Gnome startx, and once it does start applications will not run. Also, when I try to use sudo (from any environment, even ssh), it is a long time (5-10) before the command is executed.
I cannot say for sure, but it seems like this is an intermittent problem. Sometimes X takes a long time to start, but once it starts it will launch programs. Sometimes X takes a long time to launch, but once it starts it will only launch certain programs. Though presently X always takes a long time to start, and I cannot successfully launch any programs.
A while back a had a similar problem to this (x taking long time to start, sudo taking long time to execute) and it ended up being a DNS problem. Unfortunately, I cannot remember exactly what it was and I stupidly did not document it. Maybe this is also DNS related, I don't know.
I don't know what log files to look at for problems with X, Gnome, and sudo taking a long time to start.
