On the following link Following code is given
Code:
loopbit = loops_per_jiffy;
/* Gradually work on the lower-order bits */
while (lps_precision-- && (loopbit >>= 1)) {
loops_per_jiffy |= loopbit;
ticks = jiffies;
while (ticks == jiffies); /* Wait until the start

Here is my situation:I have a series of .plt files that are geared for a device that has it's xy origin at the lower left of the paper however some devices use the center of the paper as it's origin in a piped shell script how can I convert this file to a center origin plot file?Here are some knowns: the existing file always Lower Left 0.0 the existing file max xy is the page upper right x.x the desired output file must have it's 0.0 at the exact center of page (page size will vary). Ideas: Based on the sample files included maybe use PU and PD as the triggers for inputs to be calculated as any other commands have nothing to do with coordinates.

I've recently started coding in bash and I'm making a diagnostic check CD for rackmounted computers to print out to an LCD screen. So far it works but what i want it to do is, when it checks what ethernet ports are unplugged, it stays there for 30 minutes or so and proceeds through the script. I've looked up cron and that seems to be useful for making timers on permanent systems but I just want the cd to boot, do the check and then eject it and let the real OS take over and I've also tried using:
while [ `sleep 30m` ];
do
<script>
with no luck. Is there any command I can use to do this? I've noticed a few examples where people have captured the time and then used a while less than/greater than statement but I'm not sure how to do this. Is it possible to do a concept like:
while [ %current time -lt %current time+30 min ];
do
<script>
I'm trying to understand how interrupts work. Is there a way to generate timer interrupts in C. Also can we enter into the protected mode of the CPU. Does OS (specifically, linux) place any restrictions on user programs entering protected mode. If it does not, do we just have an assembly language program which changed the mode, followed by the C code... I'm just trying to understand how things work at the lowest level. So I'm trying to write few snippets to test my understanding.

I'm implementing a TCP protocol. TCP implementation requires to send packets continuously and if the receiver doesnt respond after a particular interval of time it should resend the packet again. I need some method to implement a timer expiry function. How can I implement it? Should i implement threads (If yes can you please give a sample)? or is there any better method? I'm implementing it in a Unix system.
View 3 Replies View RelatedAfter GRUB 2 comes up (I'm running Ubuntu 10.10) and I choose the OS to boot, there is about a 5 second delay where nothing appears to happen after I make the selection -- no disk activity. It happens consistently every time I boot. Again, this is after I choose the OS to boot, so it shouldn't have anything to do with the standard delay to allow me to choose the appropriate OS.Is there a good way to troubleshoot this and determine what is causing the delay?
View 4 Replies View RelatedI am having problems with the useradd command. When I call "useradd someuser" the program starts and never finish. When I give the UID option (useradd -u ) sometimes it works properly, but with some UID's that aren't in /etc/passwd it shows a message saying that the uid is not unique. I checked out /var/log/auth.log and nothing about the command is being logged. It seems that the command is not calculating the new UID prperly.It's running on a Debian Linux 2.6.26-2-686 i686 GNU/Linux

Where is .3Gb gone ? Again, it is a 64 bit machine..so should see all 8Gb. Is it mistake of top command calculating 1Gb=1024*1000Kb ?

I am basically from system side and often confused about the calculation of the IP addresses.Just i want to know that what how can i calculate the following of a IP Address:
(1) Available IP in a Network
(2) Broadcast IP
(3) Network Prefix or Net Mask
i am working on a model based on cpu load / cpu usages. where i need the instant cpu usage/cpu load, but i can able to find the cpu load average for last 1 , 5 or 15 minutes. Is there any command or any software by which i can able to find out that?
View 2 Replies View Relatedipcalc isn't the one I am thinking of. I remember another one that was a bit better, with more options -- easier to use.I remember that if you gave it a CIDR network /23 and an IP, it would list all of the address ranges, network, broadcast for that network..

I started seeing error log entries to this effect once we ported a Tomcat webapp, which connects to a remote database, from Tomcat 5 to Tomcat 6.0.26, but it seemed relatively harmless until now. The error we got at first was:

SEVERE: A web application appears to have started a TimerThread named [Timer-7] via the java.util.Timer API but has failed to stop it. To prevent a memory leak,the timer (and hence the associated thread) has been forcibly cancelled. A restart seemed to cure the server at that point. But now it has died silently: though the process itself was running, the service become unavailable. Entries like this were found in the logs:
