This is probably a simple question but I really don't know!How do you measure a case fan to know it's true deminsions whe one is talking about them or whatever?For an example lets use an 80 mm fan, is it measured from the "Frame" size witch is the total size of the fan or what?

mkisofs 2.01
I do 'mkisofs -iso-level 1 -o image John Smith.txt'. Only an example. When I mount image, ls outputs john_smi.txt. So it has shorten to 8.3 and translated ' ' into '_'. This is in accordance with the manual, although it doesn't say the conversion will be done.

-iso-level level
.........................
With all iso9660 levels from 1..3, all filenames are restricted to upper case letters, numbers and the underscore (_).

However, as it did not reject the file name, it should have converted it to all upper case, it seems to me. And -iso-level 2|3 does the same thing.
Code:
root@darkstar:~# mkisofs -iso-level 1 -o image John Smith.txt

I am a beginner to C and C++ and so far I have learned two ways to measure the time my program takes to run.
Method 1: Just compile your C file and if the executable is say a.out just type time ./a.out
Method 2: Here the general structure of the code is
Code:
#include<stdio.h>
#include<time.h>
int main(void)
[Code]....
Question 1 Do Method 1 and Method 2 return the same times?
Question 2 Method 1 gives three times real, usr and sys . Is it true that USR+SYS= TIME GIVEN BY METHOD 2
I have performed some experiments with small codes which return the squares of numbers uptill 36000 and I feel the answer to question 2 is yes
I was wondering if there is a way to see how much power my computer is using while using Ubuntu. I know there are hardware devices, plugs, I can use but I didn't know if there was a computer program that I could use that would do the same thing. I am currently using an IONITX F-E, 2Gb 800mhz RAM, 6 Green WD 2TB drives, and plan on getting a blu-ray drive installed in the last slot. I am also using a PCI-E x4 SATA card, and using software raid 5. I have a 350 watt psu installed and would like to remove it and install a pico-psu but the pico seems to max out at 200 watts.
View 2 Replies View RelatedI've found various programs and methods to measure FLOPS, but I don't seem to understand them. What is wrong with the following?
test-flops.py
Code:
#! /usr/bin/env python
float_increment = 1.03 # random
start = 57.24 # random
floating_point = start
for i in xrange(10 ** 6):floating_point += float_increment
Code:
PROMPT$ time ./test-flops.py
As far as I can see, this times a program that performs 1 million FLOPs (namely incrementation).
This outputs about 1.2 seconds on my (reasonably fast) machine, giving 840kFLOPS, which is much too low.This post may be in the wrong section; a C translation increments the result by three orders of magnitude (ie, py sucks), but this is still considerably less (~ 7-fold) than published values.
I am using a simple plain Debian Lenny base system (No X). I would like to measure how many seconds my system takes to boot - time between hitting enter key on GRUB screen to login console on tty1.One obvious way is to measure it manually by looking at your wrist watch or an external timer but I would to measure it more accurately - something that is built inside the Operating System.

They have 4 pin connectors, so I was just going to plug 2 of them into the 2 available fan headers, and then plug the last one into a molex connector considering that they all come with molex adaptors. However, according to this site, your not supposed to because its too much strain on the motherboard? I am not (never have never will) overclocking so is that just for overclockers?
