I am trying to understand a large amount of allocated memory that seems not to be accounted for on my system.I'll say up front that I am discussing memory usage without cache and buffers, 'cause I know that misunderstanding comes up a lot.I am in a KDE 4.3 desktop (Kubuntu 9.10), using a number of java apps like Eclipse that tend to eat up a lot of memory.after a few days, even if I quit most apps, 1 gb of ram remains allocated (out of 2 gb).this appeared excessive, and I took the time to add up all values of the RES column in htop (for all users).the result was about 1/2 gb.am I trying to match the wrong values?or could some memory be allocated and not show up in the process list?this is the output of free
Code:
total used free shared buffers cached
Mem: 2055456 1940264 115192 0 123864 702900

This has only been happening since I got back from a trip to Australia, where I naturally changed the computer's timezone to match the local one. I'm now back in Central European Time which is 10 hours behind Australia's. This is on opensuse 11.3.
I've used the YAST date and time tool to set the timezone correctly, and /etc/localtime is set correctly:

I ran a firmware test, after I discovered a bad memory stick on a 1 gb stick. Replaced my memory stick and just for grins ran a firmware test and I don't understand this:[Fail] Failed to locate HPET base [Fail] OS/2 memory hole test-The memory map has a memory hole between 15mb & 16mb.
Re-ran MEMTEST just to make sure my new memory was fine, no errors.My Linux OS appears to be running slower on boot-up than normal, What documentation there is on the internet on HPET is over my head.I ran SMART on the both drives. They were good. So I am a little stumpted.
For some reason, every time I shut down and reboot my machine, the system time advances four hours. The local time here is EDT (-4hrs UTC). I have it set correctly in Yast and have the 'hardware clock is set to UTC' checked. However, for some reason, the next time I boot, the system time will be ahead four hours.

View 2 Replies View RelatedI am running my Ubuntu 32 bit server on top of Windows 7 64 bit with VirualBox. It's a 2 core Atom. It's been working good for about half a year. But the last about 6 weeks the system time only in Ubuntu is going slow. About -8 per 24 hours! I can only guess because I have more things running in my Windows 7 and Ubuntu.
I can set it right by coping the hareware time to system time with this command:
Code:
hwclock --hctosys
I want to run a crontab to have that command run every minute. But it don't seem to run.

I'm just wondering what the limits for time are. I have a program that always takes exactly 20 ms, so I assume this is the lowest it can measure, but I want to see if there's some sort of documentation of this.

I read somewhere that you cannot have Gnome 2 and Gnome 3 installed on the same system at the same time.

Both applications create a system V shared memory segment by calling shmget.If the system boot at runlevel 5, both applications can obtain their shared memory segment id correctly, i.e. 98305 and 131074 individually. While there is a root owned segment id 32768 takes first seat on the list. This is the id list:

View 5 Replies View RelatedI don't know why but since I upgraded the KDE 4.4 desktop from openSUSE 11.3 to 4.5, the desktop just freezes some times.
If i was listening music, or watching a video I can still hear everything and even move the mouse, but nothing works.
So I switch to TTy1, perform a init 3, then init 5 to restart all the graphic system, and start again. This happens without message, without log, and without clue...
Should I downgrade to 4.4 or this has a Workaround?

View 1 Replies View RelatedIn the beginning there is MBR. MBR looks for the active partition and tranfers control to the VBR of the active partition. MBR is where grub may be installed. which allows the user to choose an OS(a VBR) I am not sure what the program in the VBR does,but it manages to loads the OS. What am I trying to do: Backup. I ma tired of losign my partitions my bootloaders. I want to backup them all! partitions/MBR /VBR everything short of creating an disk image.
My questions:
1. say the ubuntu partition is formatted, will grub still load? if not is there a bootloader that would?am I making sense? i hope so...
2. what exactly does the VBR contain ?
2. How do I go about backing up? The mbr and the partiton table are backed up with a simple dd command. Then what else needs to be backed ? VBR's of every partition?

Well I get my other 2 questions answered , I have one last question that has been buggy me.Anyone know why windows use so many files just to keep the OS going and so bloated? The under line of files of windows is messy and loads self every where and very bloated with windows and windows vista and windows 7 very much so.I'm not sure if Linux /Mac OS X is like this or not .
I know windows needs to support alot more software and hardwar but is that not where drivers come in for the hardware.And programmers need to write the software for windows or Linux / Mac OS X.
I write a little script by bash.
#!/bin/bash
a=`gawk '/Iterations /{print $0}' hoge.log | gawk 'BEGIN{FS=" "}{print ($4)}'`
a=`expr 3 '*' $a`

In my book, this is an example of a recursive algorithm:
var reverseArray = function(x,indx,str) {
return indx == 0 ? str : reverseArray(x,--indx,(str+= " " + x[indx])) ;; }
var arr = new Array('apple','orange','peach','lime');
var str = reverseArray(arr,arr.length,"");
alert(str) ;
I'm trying to understand it, I'm stuck at the (str+= " " + x[indx])) part - that part of the function definition expects an ARGUMENT, am I right? What's being passed to it is a bit of PROGRAM, the str+= stuff. So - how is it working?
