Media Access Control address, a hardware address that uniquely identifies each node of a network. In IEEE 802 networks, the Data Link Control (DLC) layer of the OSI Reference Model is divided into two sublayers: the Logical Link Control (LLC) layer and the Media Access Control (MAC) layer. The MAC layer interfaces directly with the network medium.Consequently, each different type of network medium requires a different MAC layer. On networks that do not conform to the IEEE 802 standards but do conform to the OSI Reference Model, the node address is called the Data Link Control (DLC) address.

If you want to change your network card mac address you need to use simple utility called mac changer.MAC changer is a utility for manipulating the MAC address of network interfaces

You can easily develop Qt4 projects in your KDE3 environment using KDevelop. You need to get Qt4 either from trunk/qt-copy or from Trolltech. Just follow the usual README in order to configure it correctly. No need to install it (that safely ensures you won't install over your existing Qt3).

How do you "use" Qt3 or Qt4? Just change a few variables. Qt4 basically only needs to have qmake first in the PATH variable. Open a new terminal session and set PATH to:

I bought a new laptop and setup Ubuntu 6.10 on it. Needed some customization to make it really usable.

1. Fix installer issue.
2. Install Beryl.
3. Fix resolution.

The following tutorials have been cut and pasted from other peoples sites. The links to the original pages have been provide. I just wanted to make sure they were all in the same place for future reference.

Postfix is free and powerful MTA. You can easily configure Postfix to block spam. You need to add following directives to /etc/postfix/main.cf file:

=> disable_vrfy_command = yes : Disable the SMTP VRFY command. This stops some techniques used to harvest email addresses.

=> smtpd_delay_reject = yes : It allows Postfix to log recipient address information when rejecting a client name/address or sender address, so that it is possible to find out whose mail is being rejected.

If you’ve never looked in your /tmp directory, you may want to take a gander. Sometimes it can become quite full and take up precious disk space.

If you’d like to remove all this stuff every time you shut down your box, you’ll have to do a little editing.

First, open up a CLI (Applications -> Accessories -> Terminal) and let’s edit a file called sysklogd (after backing it up of course).

This tutorial shows how you can back up and restore hard drives and partitions with Ghost4Linux. Ghost4Linux is a Linux Live-CD that you insert into your computer; it contains hard disk and partition imaging and cloning tools similar to Norton Ghost. The created images are compressed and transferred to an FTP server instead of cloning locally.

I’ve been meaning to upgrade one of my non-production machines to Feisty this last week and finally found some time to do it over the weekend. It’s actually upgrading now as I write this. I wanted to share one tip that I found in trying to upgrade, which could be simply due to my own hardware but it may affect others.

The Herd 1 or daily build CD would not boot on two of my less-than-production machines. Hopefully that’ll be fixed by final release (which I’m sure it will be). In the meantime I thought I would just manually update my repositories to upgrade to Feisty and see how that route worked for me. What I wanted to avoid though was having to download the entire mess of files again considering I already had the nightly build CD!

There are two ways you can do this:

KDE: Plasma Mobile in Randa, Calligra Suite Rant, Kubuntu Updates

  • Calligra Suite does not suit me
    It pains me to say so, but the split from KOffice to Calligra has given this program only a temporary infusion of hope, and looking back at my 2013 trial, it's not made any progress since. On the contrary. Calligra Suite is slow, difficult to use, and it comes with less than ideal file format support. My conclusion here is much the same regarding different Linux software, be it distros or desktop environments. 90% of it just shouldn't exist, and the effort must be focused on just one or two select programs with the highest quality and chance of making it big. The infinite forking doesn't do anyone any good. Calligra Suite has the potential, but it's far, far from realizing it, and the world of Plasma has left it behind. The interface split is bad, too much equity is taken by a confusing maze of options, the performance is dreadful, the stability flaky, and the rest does not scale or compare against LibreOffice, let alone Microsoft Office. I wish my findings were different, but it cannot be. Ah well. Like so many other flowers of the open-source world, this one must wilt. I'll keep an eye, but I doubt there is ever going to be enough focus or love to make Calligra into a serious competitor. Dedoimedo's sad prose out.

Red Hat and Fedora: AnsibleFest SF 2017, So-called 'Open Organisation', and Pipewire

  • AnsibleFest SF 2017
    AnsibleFest was amazing, it always is. This has been my Third one and it's always one that I look forward to attending. The Ansible Events Team does an absolutely stellar job of putting things together and I'm extremely happy I was not only able to attend but that I was accepted as a speaker.
  • The eye-opening power of cultural difference
    Inclusivity is the quality of an open organization that allows and encourages people to join the organization and feel a connection to it. Practices aimed at enhancing inclusivity are typically those that welcome new participants to the organization and create an environment that makes them want to stay. When we talk about inclusivity, we should clarify something: Being "inclusive" is not the same as being "diverse." Diversity is a product of inclusivity; you need to create an inclusive community in order to become a diverse one, not the other way around. The degree to which your open organization is inclusive determines how it adapts to, responds to, and embraces diversity in order to improve itself. Interestingly enough, the best way to know which organizational changes will make your group more inclusive is to interact with the people you want to join your community.

Ubuntu: Applications Survey, Mir support for Wayland, Canonical OpenStack Pike and Bright Computing

  • Results of the Ubuntu Desktop Applications Survey
    I had the distinct honor to deliver the closing keynote of the UbuCon Europe conference in Paris a few weeks ago. First off -- what a beautiful conference and venue! Kudos to the organizers who really put together a truly remarkable event. And many thanks to the gentleman (Elias?) who brought me a bottle of his family's favorite champagne, as a gift on Day 2 :-) I should give more talks in France!
  • Mir support for Wayland
    I’ve seen some confusion about how Mir is supporting Wayland clients on the Phoronix forums . What we are doing is teaching the Mir server library to talk Wayland in addition to its original client-server protocol. That’s analogous to me learning to speak another language (such as Dutch). This is not anything like XMir or XWayland. Those are both implementations of an X11 server as a client of a Mir or Wayland. (Xmir is a client of a Mir server or and XWayland is a client of a Wayland server.) They both introduce a third process that acts as a “translator” between the client and server.
  • Mir 1.0 Still Planned For Ubuntu 17.10, Wayland Support Focus
    Following our reporting of Mir picking up initial support for Wayland clients, Mir developer Alan Griffiths at Canonical has further clarified the Wayland client support. It also appears they are still planning to get Mir 1.0 released in time for Ubuntu 17.10.
