Gnome Calculator Percentage Sum
location: ubuntuforums.com - date: July 4, 2008
A slightly dimwitted question but for the life of me can't seem to subtract a percentage using Gnomes Calculator? (to use to windows)
8.95 - 25% = error (should be around 6.70)
Ive read the docs for it, theirs no real comment other than:
Percentage % Divides the current value by 100. 560 % = 5.60
Is there any way I can decrease my CPU temp in Ubuntu?
location: ubuntuforums.com - date: June 3, 2013
Hello everyone. I haven't used Ubuntu in a while, but now that it appears to be working better with the graphics card in my new laptop, I decided to come back.
I just installed 13.04 and I noticed that my fan is always on (it is only selectively on in Windows). I installed several programs, including lm-sensors (and ran sensors-detect) fancontrol, but I'm not entirely sure what to do with these. I then monitored the core temps using...
watch -n 1 -d sensors
...and found that the idle temp for my CPU is roughly 68C. Now, I have an HP Envy 14 with a quad-core i7 processor and a switchable HD Radeon card (I don't remember which one), so it is going to run a bit hot. AFAIK, Ubuntu only utilizes my lower-end Intel HD GPU. I am fine with this and don't really need the other one for Ubuntu, but I would think that it should run cooler than it does in Windows. Plus the fan sound is a tad irritating.
I know this is a dumb question, but is there any way I can make my laptop r
What is a good Scientific/Graphing Calculator Application for Linux/OSX/Windows?
location: linuxquestions.com - date: July 5, 2013
I'm currently in college and trying to cheap out on buying a standalone calculator, when I have this wonderful PC in front of me. I saw a few like, ExtCalc, or GNU Plot, but I'm having issues using ExtCalc on Windows under Cygwin, and GNU Plot seems to have a steep learning curve. I don't mind a bit of programming, as long as the way to use the programming is clear, and easy to follow.
I wanted to find something that could act as a scientific calculator, or graphing calculator for the different operating systems that I could use across all of them, or at least compile on all of them so then I wouldn't have to relearn a new system each time.
High nice percentage in top on busybox
location: linuxquestions.com - date: February 22, 2010
I cant understand the output of my top, specifically the nice percentage at 96.8%.
I know that the nice value of a process is basically it's priority and I think a high nice% means the CPU time is taken running task(s) with high nice value (low priority).
But which process is taking the cycles? my top output is:
Mem: 17284K used, 108368K free, 0K shrd, 5220K buff, 8980K cached

I/O wait CPU percentage definition
location: linuxquestions.com - date: July 23, 2007
We run RH AS3 and AS4 in the enterprise.
The DB machines are fiber connected to a SAN.
We run Oracle DB (v9 and 10g)
On one application in particular (AS3) we have consistently seen high i/o wait numbers. The percentage would go as high as 99%, but more often it would be between 40 and 80%.
From my checking the OS is doing fine, it is waiting for response from the SAN. But should that keep the CPU's (4 of them) all at 80 or 90% busy?
What is the CPU doing at that time ....i know it's waiting for data, but what is it doing to make the % go so high.
I equated it to the CPU going to the door, and opening it looking for data, but none is there so it goes back to it's easy chair. Then ..it's still waiting so it gets up again and goes to the door.
The problem with this is we have 4 CPU's all showing that high i/o wait busy and management does not like my answer. Now I'm begining to question it and I'm looking for any info that might help explain what is happening.
setting gcstaletime does not decrease ARP requests
location: linuxquestions.com - date: October 27, 2013
in trying to reduce the frequency of ARPs sent from my router to modem, I would think setting gc_stale_time on the interface to a higher number would do it - 600 in this case for 10 mins. But I still have ARPs sent a few times every minute:

Please does anyone know or have a link to an article that suggest that most of the worlds servers run on Linux instead of Windows?
I will really appreciate the link.
Thanks in advance
HOWTO: Set maximum CPU consumption in percentage by any process
location: ubuntuforums.com - date: November 25, 2008
EDIT: Tutorial was last updated on September 15, 2011. New features added to scripts and some bugs fixed.
Purpose of cpulimit daemon:
Daemon runs in background and checks if some process is consuming more then 20% of CPU and if it does then daemon lowers CPU consumption of particular process to maximum of 20%. The goal is to have no single process that consumes more then 20% of CPU power.
Note: If you would like to omit only one process then you don't need this "cpulimit daemon". In this case you only need cpulimit program to be executed from terminal.
Cpulimit daemon was tested on Ubuntu 8.04 LTS and Ubuntu 10.04 LTS. However it should be running fine on other Ubuntu versions and also on other Linux distributions, because it does not uses any Ubuntu specific code.
1. INSTALL PACKAGES
1. Install cpulimit package.
sudo apt-get install cpulimit
2. Install gawk package.
sudo apt-get install gawk
2. CREATE CPULIMI
bash cut command to get df percentage

I'm trying to get bash to return the percentage free disk space as an integer using df and cut, but it doesn't seem to work. I'm trying
df /home | cut -f5
but it just echos as if I had typed df /home
Anyone know what is going on? Also, how can I just extract the value from the second line so I don't end up with
