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.

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:

    The planned obsolescence is even worse with tablets and smartphones, whose components are all soldered down. The last tablet with a removable battery was the Dell Venue 11 Pro (Haswell version) announced in October 2013, but it was an expensive Windows device that cost as much as a mid-range laptop. The last Android tablet with a removable battery was the Samsung Galaxy Note 10.1 (GT-N8000 series), released in August 2012. It is still possible to find mid-range smartphones with removable batteries. Last year the only high end phones with removable batteries were the LG G5 and V20, but even LG has given up on the idea of making phones that will last longer than 2 years once the battery starts to degrade after roughly 500 full charge and discharge cycles. Every flagship phone introduced in 2017 now has its battery sealed in the case. According to the gmsarena.com database, the number of new smartphone models with non-replaceable batteries grew from 1.9% in 2011 to 26.7% in 2014, and now to 90.3% in 2017. It is highly likely that not a single model of smartphone introduced next year will have a replaceable battery.
