personalisation ubuntu
 

hi for everyone
how to personalise ubuntu ?
& thank's in advanced

I'm guessing you mean the appearance of the window manager, which is done with gnome-appearance-properties, if you're using gnome. You can choose a theme as well as background, and set up your system fonts.

You might find this guide helpful (first google result for "personalize ubuntu" by the way):

thanks
but i want to build new distro based on ubuntu

Do it! The world needs more distros. :)

You should've been more clear what you meant by personalize. You can go through the Ubuntu pages to see how to rebuild the kernel for their distro, but what you're saying is that not only do you wish to alter the kernel, but also alter the RFS and the form and fit; in short make your own custom distribution. Well that's fine, but not just something included in a Wiki. I recommend you start small and create "a" distribution first and then see how much you can make it like you want, which is a mimic of Ubuntu, but presumably better. Plus, I think you can contribute to Ubuntu, I thought it is a community distribution for starters. From there you can learn how they create what they have now and gain some expertise in how to make a distribution in the first place.

How so you want us to give you tips and info, if you didn't even post what is your hardware,you only can do so much in a distro depending on you resources!.

I want personal ubuntu also:
 

but mine would have NO Password. Admin requests on a single use computer is not needed or wanted. I am the only user. I want my first amendment back, second amendment freedom to shoot the (da-n) gate keeper. my brain memory doesn't remember well any more! Anyone with news of this freedom? NO PASSWORD

Freedom of speech has nothing to with computer security. That's sort of like comparing apples and fish.

You may be convinced that no malicious person will ever sit at your computer's keyboard and you may be right. Nevertheless, if someone breaks into your computer remotely over the network, the Linux security model of not doing day-to-day usage with administrator rights provides a level of security. It's not absolute--no security is or can be--but it is an additional layer of protection.

If you want vulnerable computing, find a distro that allows you to log in and use the GUI as root. Such distros exist.

You might be the only human, but you are certainly not the only user.

I'm not sure whether you have noticed but even iOS (often touted as the "easiest system to use") asks for a password before installing applications.
If you want to behave in a silly manner then do so but I wouldn't expect anyone with any knowledge of or experience in computing to help you.

Cyber Criminals Hack Refrigerator to Send Malicious Emails

Sure it can sound far fetched. I work in mostly embedded systems, stuff exactly like the computer for a fridge, or a coke machine. Over the years, the machines have increasingly become network aware so that they can report things like fault statistics or sales to the manufacturer. In the past, much of the communications has been proprietary, a cell phone calling specific numbers, because things like P.O.S. (Point Of Sale) machines are "anywhere" and hence the owners/manufacturers have had to develop and support their own communications network to obtain these statistics. Their bottom line is "an empty, jammed, or not operating machine costs them sales", or "an unused machine, costs them money and is better relocated elsewhere". Business driven is their bottom line.

Now consumers are getting smart home appliances, and even though they tie those appliances into a secure home network, this doesn't mean the "system" is secure. Many of those systems are based on Linux or a simple RTOS which supports network stacks. These hackers have found ways to exploit protocols which are mainly supported as part of a default Linux install. Therefore if you have an un-secure system, your CPU time can be used for purposes not under your control and probably not meeting with your approval.
