I was bored, Here is a little example of what VirtualBox can do in Ubuntu Running Windows And Linux Mint Side by side.
I only have a 3.0 ghz with 1 Gig of ram running XP/Mint on Ubuntu Gutsy and I can switch through Os's without any slow down at all, I dont have any reason to run XP or Linux Mint, to me Ubuntu is far better than both.

1-Click Install Innotek VirtualBox:
Add this apt repository to your Software Sources:

deb http://www.virtualbox.org/debian gutsy non-free
The innotek public key for apt-secure can be downloaded here. You can add this key with
apt-key add innotek.asc
Then update repo's:

Click Here to install

Have a CD or DVD lying around that you are sick of putting in the drive every time you need something on the disc?

How about just making an .iso file that you can mount as you need? Or maybe you just want a “master” copy of the media so you can create another copy at a future date.

At any rate it is rather easy to accomplish in Ubuntu:

sudo umount /dev/cdrom
dd if=/dev/cdrom of=file.iso bs=1024

You can also do the same with folders:

mkisofs -r -o file.iso /location_of_folder/

Don’t forget to make a checksum:

md5sum file.iso > file.iso.md5

Features:
*Set Session Settings, Change Splash Screen, Change Services
*Change Icons,Compiz Fusion Tweaks, Gnome Tweaks, Nautilus Tweaks
*Enable BurnProof Technology in Ubuntu Gutsy
*Enable Overburn and show advanced Permissions in Nautilus
*Configure Power Management and Hardware settings
*Security Settings, disable run, lockscreen, printing, print setup, save to disk, userswitching, display information message when no password needed..
*Configuration Options for commonly Used applications

Hey, a bugfix and user experience improvement version of Ubuntu Tweak is now released!

In this version, it still hasn’t been added more tweak options, just one tweak option: the opacity menu with Compiz Fusion. That you can set your menu with 90% opacity by just toggling the check button on!

Other details here.

Ubuntu Tweak 0.2.1 Release Notes:

1. Removed the useless OK button;
2. When you select a father item, it will automate expand the child items;
3. The items and the content is resizable now;
4. The main window is resizable too;
5. Added a tweak option that you can easily set your menu with 90% opacity;
6. Support Brazil language(Thanks to Williams)

OK! Recommend to download.

Debian Package:

ubuntu-tweak_0.2.1-1_i386.deb

This video clip shows you how to crop a selected region from a digital photo using the Ubuntu image editor. The selected region is then used to create a new image.
Quick Tips

* The default image editor for Ubuntu is the GIMP, or GNU Image Manipulation Program.
* When using GIMP, you can always right-click on an image to bring up a full menu of options.

rtfm!

Nice lil video for newbs out there...
This video clip shows you how to use the man (manual page) command to view the manual pages for terminal commands. A manual page includes a brief description of the command as well as outlines the various options that may be used with the command.

Here is a quick & easy video tutorial on copying images from your digital camera with ubuntu, without extra software!

Gnome users only…

* Run gconf-editor (by hitting Alt+F2 or from terminal).
* Browse to apps->nautilus->desktop in the left-hand folders window
* Uncheck the “volumes_visible” option

Careful, as this will also hide portable storage volumes also…

So you want to create a VMware Server on Ubuntu Gutsy Gibbon 7.10? And you want to run it without the graphical user interface (GUI)?

Well today you are in luck. VMware Server (free), allows you to connect graphically to administer a VMware Server so there is no need to install a GUI on your VMware Server and waste precious RAM.

Let’s get started.

First off, I assume that you already have an install of Gutsy Gibbon server version installed and set to a static IP address. From here on out it is pretty easy.

All we have to do is run the following command to install a few prerequisites before we get started.

First jump to the root account:

sudo su

then:

apt-get install build-essential linux-headers-`uname -r` xinetd xorg-dev

After that is installed we grab the install tar file from VMware.com:

wget http://vmware.com/whatever-the-current-release-url-is

extract the tar:

tar xfz VMware-server-1.*

then move into the newly created directory:

cd vmware-server-distrib

Then run the install script:

./vmware-install.pl

Accept all the default options (unless you have reason not to) and you will return back to the command prompt after installation is complete.

At this point you can connect to the server via the VMware console by entering the IP address of your new VMware Server and the login credentials.

What is Xephyr ?

Xephyr is a X server that runs as a small window within your current X session.

What is it good for ?

There are multiple potential uses for Xephyr:

• Development. You can ssh into a chroot and forward X sessions.
• Forward X over ssh without VNC.

This is quite simple and very effective, I have used it a few times, its pretty convenient since it looks as if the internet is broke or something :)
Check it:

Simply:
sudo gedit /etc/network/interfaces
Then lets add the simple iptables rule to the interfaces file when the internet connection starts up...
Simply add this under auto wlan0 or auto eth0 in the interfaces file:
pre-up iptables -A OUTPUT -p tcp -m owner --uid-owner mykidsusername -j DROP
Ok now you can try it out:
type in the terminal:
sudo iptables -A OUTPUT -p tcp -m owner --uid-owner mykidsusername -j DROP
and switch users to the username you blocked and try to access the internet...
p00f there ya go
enjoy

Ok this is really really simple and a great feature of VirtualBOX Now you can simply run Windows XP/Ubuntu at the same time concurrently while switching in between windows applications and Linux applications! I can effectively run XP and Ubuntu at the same time on my Intel HT 3.0 ghz 768 meg ram flawelessly and my box isnt even top of the line. Check out some screenshots:

Hell yea, im excited to share this little howto! OSS Has enlightened my life and made my linux/unix experience more desirable, my volume is louder, my sound quality rocks, stereo is actually stereo, surround sound actually works now... I can enjoy more music more!
The OSS project was initially free software, but following the project's success, Savolainen started the company 4Front Technologies and made his support for newer sound devices and improvements proprietary. In response, the Linux community abandoned OSS and development effort switched to the replacement Advanced Linux Sound Architecture (ALSA). Many free software operating systems such as Linux and FreeBSD continued to distribute previous versions of OSS, and continued to maintain and improve these versions.

In July 2007, 4Front Technologies released sources for OSS under CDDL and GPL licenses, now OSS v4


Howto Install:
First lets download OSS 4:

wget http://www.4front-tech.com/release/oss-linux_v4.0-1008_i386.deb

sudo dpkg -i oss-linux_v4.0-1008_i386.deb

lsmod | grep snd

sudo -s

nano /etc/modprobe.d/blacklist

# blacklist alsa
blacklist snd_intel8x0
blacklist snd_ac97_codec
blacklist snd_pcm
blacklist snd_timer
blacklist snd

sudo reboot

I just did this on Gutsy, and I thought that it might be worth sharing as a simple way to set up a persistent VNC server. If you dont know what VNC is, its similiar to Remote Desktop for wind0ze. This is accessible using regular vnc viewers, and through java-enabled browsers. That's right, you work on your computer through a browser.

1) Install packages | click here for 1 click install
sudo aptitude install x11vnc vnc-java
2) Set up password to allow clients to view
x11vnc -storepasswd
3) Open up ports 5800 and 5900 on your firewall

4) Run this command:
x11vnc -forever -usepw -httpdir /usr/share/vnc-java/ -httpport 5800

That's it!

And an optional step 5:

5) Add the command from 4) to your sessions, so that it starts at each login

If you want to test it out on a browser, type this in the URL field:

25.542.161.414:5800

Of course, replace the 25.etc. w/ your external IP address.

Addendums to this are welcome, such as how to make it more secure. I just thought it'd be nice to have a quick and dirty tutorial for getting this set up easily.

Ok I have almost always had a seperate home partition, excluding the 3-10 times I have completely crashed my system and had to redo it all.

Reasons you should use a seperate home partition:
1. Easy backup/restore.
2. You can simply rm -rf / and pop in a livecd and be able to mount your home partition as /home without deleting users home directories and files.
3. You can use multiple linux Distro's with the /home partition
4. You dont have to worrie about the hassle of re-installing or upgrading ubuntu because everything you need is in your /home directory, you can simply backup all your apt packages via aptoncd.

Howto:
1. Reboot/Boot up your ubuntu live cd.
2. sudo aptitude update && sudo aptitude install gparted ntfsprogs
3. Then, press Alt-F2 and type:
gksudo gparted
4. In GParted, find the partition you want to resize in order to make room for your upcoming /home partition. In this case, I'm resizing /dev/hda5, but your partition may be different. Be sure to keep track of the names of your partitions--these names are very important (/dev/hda1, /dev/hdb1, /dev/sda2, etc.).
5. Right-click on the partition and choose the Resize/Move option.
6. Choose the new size you want.
7. Then, in the new empty space, right-click and select New.
8. Choose to create the partition as Filesystem ext3.
9. When you're satisfied with your new partition layout, click Apply
Once the changes have been applied, make note of the partition name of your new partition and then quit GParted.

Now, my original partition that I shrunk was /dev/hda5, and it created a new partition called /dev/hda7, and my /home folder lives on /dev/hda1. It's very important that you substitute in your own appropriate partition names for the ones I'm using--you most likely will have only two partitions you're dealing with--the one you shrunk and the newly created one.
Ok sweet now that is done, all we gotta do now is setup the new partition to be used...
Now, back in the terminal, I'm going to mount /dev/hda1 and /dev/hda7:

sudo mkdir /old
sudo mount -t ext3 /dev/hda1 /old
sudo mkdir /new
sudo mount -t ext3 /dev/hda7 /new

cd /old/home
find . -depth -print0 | sudo cpio --null --sparse -pvd /new/
sudo mv /old/home /old/home_backup
sudo mkdir /old/home

sudo cp /old/etc/fstab /old/etc/fstab_backup

sudo nano /old/etc/fstab

# /dev/hda7
UUID=8b89a5c4-20ff-477c-a49e-c1ccb435bf11 /home ext3

sudo rm -rf /home_backup

sudo mkdir /recovery
sudo mount -t ext3 /dev/hda1 /recovery
sudo cp -R /recovery/home_backup /recovery/home
sudo cp /recovery/etc/fstab_backup /recovery/etc/fstab

Hey just ran across an easy way to make symbolic links in ubuntu, I was missing out the the right click create shortcut feature in windows but in Ubuntu its easier...
Howto:
All ya do is simply hold in ctrl and shift and drag then drop a folder/file and it creates a virtual symbolic link ;)
By default, the file manager adds an emblem to symbolic links.
Note:
The permissions of a symbolic link are determined by the file or folder to which a symbolic link points.

This is a simply yet effective way I personally add/remove packages in ubuntu when I change distro's and need to reinstall everything other than aptoncd which I have an article for, my site search will bring it up searching for "aptoncd". Basically the idea is to add all your favorite packages to a text file and install them all with a simple command as well as removing them:

simply make a text file with packages you like after you add the right repositories, I simply:

echo "deb repository.com repo/">>/etc/apt/sources.list

I just found a new tool called regexxer, im sure it has been around for a while but I just discovered it.
regexxer is a nifty GUI search/replace tool featuring Perl-style regular expressions. If you need project-wide substitution and you’re tired of hacking sed command lines together, then you should definitely give it a try.
simply apt-get install regexxer

Remastersys will 'remaster' your existing Ubuntu based distro into a live cd/DVD. Tools like PCLinuxOS's mklivecd have been around a while and proved to be very popular but are tricky to get working with the newer releases of debian/ubuntu, so some guy (apologies, forgot your name) over at Linux Mint (an ubuntu-based distribution) made this really cool tool. And although it has only really been in popular use since about March this year, it has already been compared to the maturity of mklivecd.
Install:
Add the Linux Mint repo to your /etc/apt/sources.list
echo "deb http://www.linuxmint.com/repository romeo/" >>/etc/apt/sources.list
do a "sudo apt-get update"
then:
"sudo apt-get install remastersys" and it should install fine.

Then simply type "sudo remastersys" to get the list of options, which include:
backup - backs up your system including your /home folder with your users on it.

dist - omits the /home folder thus making it a distributable cd that you can give to your friends.

clean - removes the temporary folder that was created, including the new iso so burn it and copy it elsewhere before you run "sudo remastersys clean"

Well, prefetching isnt a new topic but there is possibility that it can be optimized into the next generation of computing...

I found an interesting Google SoC Project page that shows some promise, ive been searching around for prefetching and ReadyBoost solutions for Ubuntu and ran accross this...

From here:
In todays computer systems the main bottleneck is not CPU but disk access which is several orders of magnitude slower than CPU and memory. In such circumstances the way to improve application performance is to prefetch data it needs from disk before it even requests it and it is the point of prefetching techniques.
The example of prefetching solution is Windows prefetcher.


Here is a little bit from their thesis:

"In this thesis we develop preload, a daemon that prefetches binaries and shared libraries
from the hard disk to main memory on desktop computer systems, to achieve faster
application start-up times. Preload is adaptive: it monitors applications that the user
runs, and by analyzing this data, predicts what applications she might run in the near
future, and fetches those binaries and their dependencies into memory.
We build a Markov-based probabilistic model capturing the correlation between every
two applications on the system. The model is then used to infer the probability that each
application may be started in the near future. These probabilities are used to choose
files to prefetch into the main memory. Special care is taken to not degrade system
performance and only prefetch when enough resources are available.
Preload is implemented as a user-space application running on Linux 2.6 systems."

Howto test optimizations:
*Warning* This is experimental and I have not tested this yet, I am about to once im done posting this, This may or may not be correct, let me know of any issues!

The following is an edited version of there wiki located here

Testing Boot Prefetching and Applications Prefetching

Introduction

First testing version of kernel with automatic boot prefetching and tracing is available. This version is precompiled for Debian-based systems (tested on Ubuntu Gutsy, other distributions might not work). The kernel is standard Ubuntu kernel with these prefetch patches.
Standard disclaimer applies: this is experimental version, it might damage your system use at your own risk and only on systems where you have backups.
*This Requires Ubuntu Gutsy*
Installation
In order to use kernel with prefetching:
Download kernel linux-image deb
Download linux-headers.deb
Install linux-image deb package
Install linux-headers deb package
Remove readahead package using: sudo apt-get remove --purge readahead -
please note that this will cause removing (x/k/edu)ubuntu-desktop package.
Download userspace prefetch support deb and install it using:
dpkg -i prefetch*.deb
Now reboot and select "kernel 2.6.22.6pf.3" during boot.
Uninstallation
In order to remove kernel with prefetching:
Reboot into standard (non-prefetching) kernel.
Remove prefetch userspace support files using apt-get remove --purge prefetch
Install readahead and (x/k/edu)ubuntu-desktop package.
Remove linux-image package with prefetching support (with "pf" in name).

With these simple directions you'll be able to use a USB pen prive as an additional swap. As a result, the pen drive will be used in the same way Windows Vista does through the ReadyBoost functionality.

1) Plug the pen drive in your usb slot, usually in front of your tower or side/back of your laptop.
2) Ubuntu should auto-mount the device (usually in /media/usbdisk*), umount the device (ie., sudo umount /media/usbdisk);
3) Find your usb device in your terminal by typing sudo df -h; in this example we will use /dev/sda1
4) sudo mkswap /dev/sda1 (assuming /dev/sda1 is the correct device for the connected usb device)
5) sudo swapon -p 32767 /dev/sda1

Ok now you are using the usb device for swap; when your ram is exhausted it will start using your usb device for ram

To verify that everything is working correctly do a;
cat /proc/swaps
This is the output I recieve on my Desktop;
/dev/sda5 partition 1646620 33952 -1

Just a note:
You will not recieve the same performance as ram, it all depends on the speed of your usb disk, you will notice a big difference in running games, development studio's, audio/video editing and memory hogs like firefox/openoffice.

To turn ReadyBoost for Ubuntu off in a terminal type:
sudo swapoff /dev/sda1

The OpenXML Translator provides support for opening and saving Microsoft* OpenXML-formatted word processing documents (.docx) in OpenOffice.org. So now we all can use the docx extention *yay* although im not very happy about this, id rather have hundreds of companies use *.odf and do away with this addon all together but... This is hot for those that like to use Microsh!t document formats...

Install:
1. echo "deb http://ubuntu.org.ua/ getdeb/" >>/etc/apt/sources.list
2. apt-get update
3. apt-get install odf-converter

or simply download here

Note:You must restart OpenOffice Writer to get the option available on the Load/Save document dialogs.

If you need support for windows or SUSE® Linux Enterprise, SUSE Linux, and openSUSE check out the developer's download site here

My friend Luca Cappelletti is kicking ass rolling out yet another fine release for mobile or non-root users or people that just want to download a program and start running it without wasting time installing a thing.

ioMozilla Sunbird® is a cross-platform calendar application, built upon Mozilla Toolkit. Our goal is to bring Mozilla-style ease-of-use to your calendar, without tying you to a particular storage solution.

pic by markcarson.com

Luca has told me he has modified Sunbird to have the ease of use and look of Apple iCal, stay tuned for screenshots from me! Or beat me to it and post em :)

Easy install:
Simply grab ioSunbird here
chmod +x ioCalendarSunbird0.5-feisty_InfodomesticObjects0.8.6
or simply right click on the file to change properties to executable.
mv oCalendarSunbird0.5-feisty_InfodomesticObjects0.8.6 ioCalendarSunbird
or right click rename :)
Then double click or ./ioCalendarSunbird

Check this out, same great Gftp client but without the headache of installing, this is another InfomesticObjects Linux Release.

Benefits:
Easily access ftp sites on the go or run gftp without installing at a computer with no root privileges.

Here is Gftp's Main Features:

If you forgot you password for your ubuntu system you can recover using the following steps

Turn your computer on.

Press ESC at the grub prompt.

Press e for edit.

Highlight the line that begins kernel ………, press e

Go to the very end of the line, add rw init=/bin/bash

press enter, then press b to boot your system.

Your system will boot up to a passwordless root shell.

Type in passwd username

Set your password.

Type in reboot

If this doesnt work you can alternatively try this:

Turn on your computer, and as soon as you the Press Esc to enter grub message, press the escape key.

Select the option that says (recovery mode).

Your PC will boot into a shell. Once you get a command prompt, type "passwd username" where the username is your username.

Enter a new password when prompted, and again when prompted again

Type reboot to reboot your system

Another way is to boot into the system via a live cd open up Applications->Accessories->Terminal
then mount your ubuntu drive if its on /dev/sda1 do this:
mount /dev/sda1/ /media/sda1
Then we chroot into the system:
chroot /media/sda1
passwd user
Now change the password, and reboot your box!

If you download your movies and tv series only as scene releases, then you'll have to extract the release's video file from its multiple rar files. That can take some time... Not a horrible long time. You can live with it... But I learned a cool thing and thought I could share it just because I have nothing better to do...

You'll need the packages "unrar" and "vlc" (or "mplayer" or any other video player you may prefer).
Write this in a terminal if you haven't got the required packages:

This guide intends to show how to successfully compile a fully featured svn mplayer with all the codecs and with the GUI player gmplayer. It is a bit of a difficult one so make a cup of tea and get your keyboard ready!!

Firstly install subversion, compiling tools and checkinstall and secondly download the svn mplayer plus the full codec pack:

Do you want to browse your iPhones’ filesystem on your Ubuntu machine? Follow these instructions and you’ll have it working in no time flat.

lsof

lsof is the Linux/Unix über-tool. I use it most for getting network connection related information from a system, but that's just the beginning for this amazing and little-known application. The tool is aptly called lsof because it "lists open files". And remember, in Unix just about everything (including a network socket) is a file.



** lsof is also the Linux/Unix command with the most switches. It has so many it has to use both pluses and minuses.

usage: [-?abhlnNoOPRstUvV] [+|-c c] [+|-d s] [+D D] [+|-f[cgG]]
[-F [f]] [-g [s]] [-i [i]] [+|-L [l]] [+|-M] [-o [o]]
[-p s] [+|-r [t]] [-S [t]] [-T [t]] [-u s] [+|-w] [-x [fl]] [--] [names]

As you can see, lsof has a truly staggering number of options. You can use it to get information about devices on your system, what a given user is touching at any given point, or even what files or network connectivity a process is using. lsof replaces my need for both netstat and ps entirely. It has everthing I get from those tools and much, much more.

The -t option returns just a PID
lsof -t -c Mail

350

ps aux | grep Mail

daniel 350 0.0 1.5 405980 31452 ?? S Mon07PM 2:50.28 /Applications/Mail.app



Advanced Usage

Using-a allows you to combine search terms, so the query below says, "show me everything running as daniel connected to 1.1.1.1"
lsof -a -u daniel -i @1.1.1.1

bkdr 1893 daniel 3u IPv6 3456 TCP 10.10.1.10:1234->1.1.1.1:31337 (ESTABLISHED)


Using the -t and -c options together you can HUP processes
kill -HUP `lsof -t -c sshd`

You can also use the -t with -u to kill everything a user has open
kill -9 `lsof -t -u daniel`

lsof +L1 shows you all open files that have a link count less than 1, often indicative of a cracker trying to hide something
lsof +L1

(hopefully nothing)



Conclusion

This primer just scratches the surface of lsof's functionality. For a full reference, run man lsof or check out the online version. I hope this has been useful to you, and as always, comments and corrections are welcomed.

Hey I dont do my own hosting but I found out a great hosting solution for ubuntu, check it out and let me know what you think..

Easy Hosting Control Panel is designed for hosting of multiple domains on single machine.
It uses LAMP(LinuxApacheMysqlPhp).
Its aim:easily installable,easy usage, non-complex,functional.

Why use a control panel? Because hosting a domain in an ubuntu/linux system requires many settings to be done. hosting control panel makes these tasks easy, with webbased interface.
hosting means putting web pages on the internet for general use, as you do now..

ehcp is the first control panel in this field with its unique features such as: complete php based, object oriented, opensource and free. even install is using php, so it is extremely easy to learn and extensible..

There are many free hosting control panels, but none of them have these features. some have non-opensource code, some other then php, some is not object oriented..

ehcp is in beta stage. there are many things to do. but the main skeleton is built in a straight forward way.

version 0.18.1 released !

feature overview:

* php and apt-get based simple install,
* automatically installs and works: dns, apache, mysql, ftp, email, domains,
* most easy install: copy & paste in console and watch
* ready to use after install - at ubuntu
* adodb and phpmyadmin included
* object oriented programming using php,
* easily extendable/modifiable...


future plans:
* reseller implementation (soon),
* subdomain implementation(soon),
* server/services status,
* different language support.. (currently english/turkish mixed)
* plugin system using php
* auto detection of apt-get and install if not present...

Installation:
simply copy and paste followin in your root console,

wget http://www.ehcp.net/ehcp_0.18.1.tgz
tar -zxvf ehcp_0.18.1.tgz
cd ehcp
./install.sh

ehcp hosting control panel primarily supports ubuntu, tested on ubuntu 7.04lts
but virtually work on any other linux distributions with apt-get installed as well.

currently it supports linux'es only with apt-get.

in future, i will also add a feature so that it will detect and install apt-get automatically if not present. this is not the case now.

but. the control panel will always be focused and tested on ubuntu.
Ubuntu will be the primary platform for it.
in fact this is natural because Ubuntu is so easy to maintain...

you can find demo at: http://www.ehcp.net/demo
since it is demo, daemon is not running, if it runs, demo becomes real...
demo username: admin
pass: 1234

You may or may not be aware that lithium ion batteries (like those present in the newer Thinkpad models) survive best when kept charged between 30%-85%. They should not be kept fully charged, and should be left off for long periods of time charged to ~%40. See here for more tips on Thinkpad battery treatment.

One way to extend the life of your Thinkpad's battery is to control the way it charges -- that is, to make sure that you keep it in the 30%-85% charged range whenever possible. This is possible easily and quickly through the tp_smapi kernel module.

(1) Download the tp_smapi code here. For the examples presented here, let's assume that you download the tarball to your home directory (~/):

This tutorial provides step-by-step instructions on how to install Xen on an Ubuntu Feisty Fawn (Ubuntu 7.04) server system (i386). You can find all the software used here in the Ubuntu repositories, so no external files or compilation are needed.

Xen lets you create guest operating systems (*nix operating systems like Linux and FreeBSD), so called "virtual machines" or domUs, under a host operating system (dom0). Using Xen you can separate your applications into different virtual machines that are totally independent from each other (e.g. a virtual machine for a mail server, a virtual machine for a high-traffic web site, another virtual machine that serves your customers' web sites, a virtual machine for DNS, etc.), but still use the same hardware. This saves money, and what is even more important, it's more secure. If the virtual machine of your DNS server gets hacked, it has no effect on your other virtual machines. Plus, you can move virtual machines from one Xen server to the next one.
