Mark Shuttleworth, the founder of Ubuntu, and Canonical Ltd., recently did an interview with Linux-Magazine Italia and he was kind enough to translate the Italian version to English and post it on his blog.
Here is a great question and answer from the interview:
3) Ok, let’s talk about the latest Ubuntu 8.04. In an interview you said that “Hardy Heron is your most significant release ever”. Well, can you talk about the main improvements of this release?
First, this is an LTS (“Long Term Support”) release that was delivered on a very precise schedule. Six months ago we committed to shipping 8.04 LTS on April 24th, and we did exactly that. As far as I know, nobody has ever shipped an “enterprise class” OS release on a schedule that precise. And not only did we do that, but we have now committed to ship the next LTS in April 2010, it will be 10.04 LTS, and we’ll set the exact date six months in advance like we did with this one. It is thanks to Debian and the free software community that it is possible for us to do this. So 8.04 LTS has proven our ability to deliver not just 18-month-supported releases on time, but also LTS releases on time. We very much hope that other distributions will follow our lead on the LTS cycle with their enterprise releases, because that will make it easier for us all to collaborate, and make all the major Linux distributions better.
Second, there are very significant new developments for Ubuntu itself. On the server, we worked with HP on their Proliant range, and with Dell on their PowerEdge range, to ensure that 8.04 LTS will be compatible with their popular x86 servers. We’re not yet certified, but we are sure that it will “Just Work”. Sun Microsystems has gone further, and has actually certified 8.04 LTS on a range of their x86 servers. This is a major step forward for Ubuntu on the server. We see an amazing amount of usage now for Ubuntu on the server – it’s the most popular server platform for several ISV’s. So it’s important that we work with server vendors, and server solution vendors. We’ve also put a lot of work into the use of KVM and VMWare virtualisation, because we see people building hundreds of virtual appliances on Ubuntu.
On the desktop, we have focused on making it easier to install Ubuntu, especially on a machine which already has Windows, where you can now install Ubuntu into a file on the Windows partition instead of having to resize your Windows partition to make a new partition for Ubuntu. That makes it much easier for people to test out Ubuntu, and hence to get a taste of free software. We have also worked on many of the common things that people want to do with their PC, such as work with photos and music, and started to improve the user experience there.

If you’re just starting out with using Linux then chances are you’ve probably seen or heard a few Linux terms that you don’t recognize. It’s typical that when you ask, or search, for help on the Internet for Linux, you’ll see some of the following terms. I’ve put them in one place for you so that the next time you see a Linux vocabulary word you don’t know, you can check back here.
APT – Advanced Packaging Tool. APT simplifies the process of managing packages on Linux by automating the retrieval, configuration and installation. Generally, you’ll find APT on a Debian or Ubuntu distro.
Bash – Bourne Again Shell is generally the default shell in most Linux distributions. When someone refers to a shell or the command line the Bash shell is usually what they are referring to.
CLI – The CLI is known as the Command Line Interface. When you open a terminal, or if you do not use a Window Manager, or X11, you are operating on the CLI.
Dependency – A application, library, or development set that a package depends upon to work.
Distro – Short for Distribution, a distro is a set of programs combined with the Linux kernel to create an Operating System.
GNOME - Can be called a “complete” desktop environment for Linux. Gnome is the default desktop on the popular Ubuntu distribution.
GRUB – Another boot loader for Linux. Allows users to have several different Operating Systems on their system at once, and choose which one to run when the computer starts.
KDE- KDE or the K Desktop Environment, is desktop environment for Linux workstations.
Kernel – The core, or “brain” of Linux. The kernel is what controls the hardware and is what every Linux distro is built upon.
LILO – Linux LOader. Similar to Grub, LILO is a boot loader for Linux. LILO usually writes to the Master Boot Record (MBR) on your device.
Linus Torvalds – The man who wrote the Linux kernel in 1991.
Man – Short for manual. If someone says “read the man page” or “rtfm” when you ask a question about a command, they want you to type “man command”.
Root – The superuser account on all Linux systems.
RPM – A package manager, which can be used to build, install, query, verify, update, and erase individual software packages. RPM is used by default on the Red Hat and Fedora distributions.
Sudo – Stands for Super User DO, allows a user to have root access without logging in as root.
Tux – The Linux Penguin
YAST – Stands for Yet Another Setup Tool. Typically used on the SuSE distro. Yast is a setup and configuration tool.
YUM - An automated update program which can be used for maintaining systems using rpm. Yum is also used on Red Hat and Fedora by default.
X / X11- Also known as the X Window System, X is a windowing system that provides the standard toolkit and protocol with which to build graphical user interfaces (GUIs). KDE and GNOME are built upon X11.
Can you think of any other vocabulary words for Linux newbies that should be on this list? Please, share your ideas in the comments below.

Here is a quick Linux tip to log your boot messages in Ubuntu. This is great for checking for any errors or failed startups that may be happening during boot.
# vi /etc/default/bootlogd
You’ll see the following lines:
# Run bootlogd at startup ?
Change No to Yes:
# Run bootlogd at startup ?
Now every time your computer restarts, a /var/log/boot file will be created.

Here is a quick tip on how to find out what host IPs are on your subnet using nmap. This is useful to find out what IPs are being used or just to know how many devices are connected to the subnet.
How to find out what IPs are being used on your subnet
# nmap -v -sP 192.168.1.0/24
You can replace the 192.168.1.0/24 address with whatever your IP and subnet is.
Also, for a cleaner output that removes the lines that tell you an IP is not used, try the following:
# nmap -v -sP 192.168.1.0/24 | grep -v "appears to be down"

It’s being reported that Acer is going to start pushing Linux on it’s Laptops and netbooks. The choice for Acer is obviously a smart financial move. Linux is open source and much cheaper then the alternative Microsoft operating systems. Gianpiero Morbello, the vice president of marketing and brand at Acer, even stated “We have shifted towards Linux because of Microsoft,” he said. “Microsoft has a lot of power and it is going to be difficult, but we will be working hard to develop the Linux market.”
This is definitely a great push for Linux. Acer has a lot of influence in the hardware market, and taking a stand against Microsoft for Linux could make other major companies think twice about what operating system they develop hardware for. However, I’m reluctant to see how Acer will go about marketing the OS on their brand of laptops. I hope they don’t plan on just having a lower cost laptop sitting on the store shelf and waiting until the customer gets home to discover that the operating system looks “different”. If done correctly, Acer could help the Linux desktop spread to more homes.

About Google Gadgets for Linux
Google Gadgets for Linux provides a platform for running desktop gadgets under Linux, catering to the unique needs of Linux users. We are compatible with the gadgets written for Google Desktop for Windows as well as the Universal Gadgets on iGoogle. Following Linux norms, this project will be open-sourced, under the Apache License.
The Windows and Mac versions of Google Desktop has provided gadget hosting functionality on Windows and Mac for a while now and the Linux version of Google Gadgets will extend this platform to Linux users. By enabling cross-platform gadgets, a large library of existing gadgets are immediately available to Linux users. In addition, gadget developers will benefit from a much larger potential user base without having to learn a new API.
There’s two main components to the application: one is a common gadget library responsible for running and presenting a gadget, and the other is a host program that allows the user to choose gadgets and run them on the desktop. Currently we have hosts written for GTK+ and QT, with the GTK+ host offering a sidebar similiar to that of Google Desktop for Windows.
