Many people will disagree with me when I say the cloud is just a server. Clouds can be classified as public, private or hybrid, but that is what it really boils down to it is a machine or set of machines providing services over the web. Certainly you can argue that cloud can provide infrastructure, platform, and the traditional application services. Talked about some of these services in earlier articles. However the internet is a network of systems that can be clearly defined. In the systems on the network can be described sort of like a road map or a set of telephone lines connected like below. It may not be important exactly how they are put together, except that we know they are there. To know who is where either by what is known as a web address or an ipaddress (sort of phone number) allows you to access part of the cloud that you wish to connect to. It is impossible to know every phone number or ipaddress by heart, so the internet has a built in phonebook known as a Domain name s...

Not mine, but interesting!!

Partial installation instructions for the NSLU2 At Your own risk. This page describes the installation of a minimal ubuntu system on a Linksys NSLU2 NAS device. We bear no responsibility if you do this as you do this at your own risk to self or the equipment. Requirements USB Key (or USB disk) to attach to the NSLU2 to carry the root filesystem (connect this before starting the installation procedure) A second machine to run an ssh client on in which you execute the installation Getting the software Get the latest installer image from: http://ports.ubuntu.com/ubuntu-ports/dists/jaunty/main/installer-armel/current/images/ixp4xx/netboot/di-nslu2.bin Corrected: old-releases.ubuntu.com/ubuntu/dists/jaunty/main/installer-armel/current/images/ixp4xx/netboot/ To install the image you need the upslug2 tool installed sudo apt-get install upslug2 Put your NSLU2 into upgrade mode Poweroff the device Hold down the reset button in powered down state...

If you set up your serial port for communications and have a serial terminal (some systems may require a usb adapter), you will never worry about not having a monitor for emergencies. (Connecting in this case to an nslu2 running linux.)   Notes from an earlier article to set up serial communication, Your system may vary. Now to get the Pda working with the unit. The Palm pda will not work as is as a dumb terminal, so I had to install a program on to it from another computer called ptelnet.prc using a usb to serial interface. The Palm has an interface cable that will plug directly into the 9 pin serial port on the back of the computer. HP Journa has a standard rs232 port. $  pilot-xfer -p /dev/ttyUSB0 -i ptelnet.prc That should be easy. First to test the port. Strange the serial port on what is commonly known as com2:. (com1: =ttyS0) $ sudo /sbin/getty -h -L /dev/ttyS1 9600 vt100 & $ sudo chmod 666 /dev/ttyS1 A prompt did not show up on the Palm pda. ...

Web servers are awesome as you can do so much from home automation to what ever your imagination can dream up. If you have an extra computer this is a great way to put it to use instead of sending it to a landfill! One way we use our web server is with a Chumby. We like to use our Chumby (touchpad) in connection with our home server. The Chumby is not exactly portable. I love our Infocast Insignia (aka Chumby) 8″. Using it I made sort of an ipad clone and it runs Linux!! I control all the home automation from it and it is great for accessing our intranet based w eb server from the kitchen to access recipes and many other applications). Becoming addicted to php and mysql as well as html. May get a second one for a low powered server like I used to do with the Cisco Linksys Nslu2. Can not wait to see how well it works with mythwebtv. Need to build a new server first. 64bit here we come. Yep, we are bit behind using only 32 bit single core cpu based computers. Picture of a...
