I don't think you have to worry about drive alignment if you're not partitioning drives. Though, mkfs.btrfs does give a method to offset where the filesystem starts, but I've never tried it.

The...

There really isn't any disadvantages to not partitioning your data drives. If you partition your drives, you'll run the risk of not having your filesystems properly aligned anyway.

Also, btrfs...

Not all linux filesystems.

BtrFS can be fragmented relatively easily. I have firsthand experience =p

Yeah. I figured that out when I started getting rid of some lines of code in my program. It started to look more like his. However, his is still faster by about 20 ms and I can't figure out why.

So I based my new algorithm on the Sieve of Eratosthenes. It seems wicked fast now, but it only works with small numbers. I can't scale it to 2 000 000, which is what the problem needs.

I get...

You're absolutely right.
I got my program to work, and it takes 874 ms to complete.

I browse the forum over on Euler (a hidden thread only accessible by those who've solved the problem), and...

I did this

#include<stdio.h>
main(void){
int primes[] = {4,5,6,7};
int i;

primes[4] = 11;
for(i = 0; i <=4; i++){
printf("%d\n", primes[i]);

I'm trying my hand at some of the Project Euler problems and one of them requires that I calculate every prime number below 2 million.

I already had a working implementation for generating prime...

I'm against it.

They require much higher maintenance
They're vulnerable to attacks
They're considered "clean energy" in terms of CO2 emission, but leaves radioactive waste that needs to be stored

I remember sudo being active for a period of time.. meaning if one does


sudo whoami
if one uses sudo again within a certain amount of time, it will not ask for a password again.. so..


sudo...

So what is it that sudo does that makes it more secure?

But doesn't su also give the power to run commands as a different user?


su username -c "command to run"

I don't know what everyone's configurations are but my desktop/laptops can suspend/resume and hibernate/resume pretty quickly.. Much faster than windows.

Besides, isn't hibernate dependent on...

It's probably the CPU monitor app that you're using. I suspect drawing the cpu usage graphs takes a toll on the CPU. Try with a commandline app, like top

exe (for me) is usually just a flash video.

You can try to find out what program started it by doing this:

ps -o ppid,comm | grep exe
The above command should give you the PID of its parent...

I used to eat chips in my dreams :P

The best part? Not having to wash my hands afterwards. (Which is also the worst part because I can't lick my fingers)

nothing says moviehacker like scrolling lines from a kernel compile.

32/64bit shouldn't really matter if you're not doing heavy things like video conversions. At least I didn't notice the difference between 32 and 64 bit on my Core 2 duo.. But maybe that's because I...

There was a question earlier in this thread about browsing the filesystem.. You can browse through folders on chrome using
