Ubuntu Blog in english

Most of us probably only use one user on Ubuntu, and probably its a little anoying to enter username and password every time you iniciate a session on Ubuntu...
But fortunately we can change this configuration, and make Ubuntu save our user details, so we don't have to type our username and password every time we start Ubuntu.
We only need to access the "Access Window" configuration in "System" menu and then "Administration". Once we've opened the Access Window configuration, in "Security" tab, we'll find something similiar to the following image:

We only need to type our username in the field, at top of the window, in this examlpe "ubuntu-blog.com", and next time we start Ubuntu we'll not be asked to type our username nor our password.

Some time ago, it was really complicated to get installed Ubuntu on a USB Stick or Pendrive, but now Ubuntu has a tool to realize the installation for us...

How? Easy! We only need to have a  Ubuntu CD Image, which we can download from the download section of the oficial Ubuntu site, then we enter the "System" menu, and enter the submenu "administration" and look for the  "USB boot disc creator" entrie.
Once we started the creater, we need to specify the path of our CD Image, we've downloaded before, and insert the pendrive, finally we need to determine how much space we want to assign to Ubuntu and how much space it'll can use to save our files on the pendrive. Also we can choose between saving our session information on the pendrive, or discard them every time we close the session (like a liveCD), enabling the field "Session information will be lost, less you save manually".

Once we finished, we start the installation by clicking on   "Create boot disc" button. This process will take some time, so here are some ideas what you can do while installation is in progress:

• Suscribe to the ubuntu-blog.com feed
• Prepare yourself a coffee.
• Leave a comment on ubuntu-blog.com

Someone said stealing?

As you know, one of our best friends Wikipedia helps us frequently with definitions. This time he told us that ext4 or fourth extended filesystem is a journaling file system developed as the successor to ext3. It was born as a series of backward compatible extensions to add to ext3 64-bit storage limits and other performance improvements. However, other Linux kernel developers opposed accepting extensions to ext3 for stability reasons, and proposed to fork the source code of ext3, rename it as ext4, and do all the development there, without affecting the current ext3 users.
