Restore the factory-set default settings

Follow these steps to restore the product's factory default settings. These steps do not reset page counts, service IDs, or other static product values.

CAUTION:These steps will reset the product's current wireless settings to factory-set default settings. Any custom settings will be lost, and you will need to reconfigure the product's wireless settings.

1. Press the Power button to turn off the product.


2. Press the Power button to turn on the product.


3. The product begins to initialize.
   While the product initializes, press and hold the Cancel button and the Wireless button (in this order) for 10 to 15 seconds (until it print a "Self Test / Device Configuration" page), and then release both buttons.

NOTE: LED lights blink until both buttons are released.

The factory default settings are restored.

Config Wireless Printer

1. Connect to the Ad Hoc Printer Network
   You should eddit the printer connection: "IPv4 Settings" -> "Method: Link-Local Only"
   
   Maybe you have to "Disconect and Connect" until you can ping the printer.
   
   To get the printer IP you have to print a "Self Test / Device Configuration" page (after connecting to the Ad Hoc Printer Network) and check it in: "Network Information" -> "IP Default Gateway" -> PRINTER_IP
   
   Take in mind that the IP could change during the configuration.
   


2. Once you are in the Printer Web-Interface, go to "Networking" and configure your wireless network.
   
   Once it's configure and working, you should be able to ping the printer in your network.
   


3. Install the last version of hplib (http://hplipopensource.com/)
   
   In the installation process, when detecting the printer, selet de second option "Network/Ethernet/Wireless network (direct connection or JetDirect)" and the printer will be automatically detected.

Why you should contribute to Open Source

An interesting opinion of why you should contribute to the Open Source.

"...Open Source projects offer you a chance to work on something that you want rather than something that others want you to work on. It is a great opportunity to work on something that is both cool and useful as well as to associate with a well known brand and all the publicity and goodwill it brings. You are free to pick and choose between the thousands of open source projects out there. Moreover, you are free to decide on how much you want to contribute. You won’t have a boss and you won’t have the pressure of deadlines and schedules..."

In Ubuntu 10.04 Server with the frame buffer enabled, seems that cause lag in the screen when is used as a guest in VirtualBox. Here is how to disable the frame buffer:

Edit the file "/etc/modprobe.d/blacklist-framebuffer.conf" and add "blacklist vga16fb" (without the quotes). Un-comment "GRUB_TERMINAL=console" in "/etc/default/grub" to prevent GRUB from starting a frame buffer.

A successful Git branching model

In this post I present the development model that I’ve introduced for all of my projects (both at work and private) about a year ago, and which has turned out to be very successful. I’ve been meaning to write about it for a while now, but I’ve never really found the time to do so thoroughly, until now. I won’t talk about any of the projects’ details, merely about the branching strategy and release management...

udev: update map between MAC addresses and interface names

...Traditionally, Linux kernels look for ethernet cards and assign interface names based upon the order the cards are detected. Thus if you were to shift the network cards around, or replace them, you may end up with a different interface name for any given card. In recent Debian (and thus Ubuntu) releases, the Udev subsystem creates a map between MAC addresses and interface names, and when it finds a new MAC address it assigns a new ethernet interface name. Thus the first time you create an Ubuntu VM, the VM server assigns a MAC address, and your VM will map it to eth0. If you clone the VM, or move it, the VM server assigns a new MAC address, and your VM maps the new address to eth1. At this point, your network configuration (/etc/network/interfaces) no longer matches the hardware, and your VM no longer sees the network. Oops.

If this is the problem, you will see messages like this in your /var/log/kern.log file:

udev: renamed network interface eth0 to eth1

You can fix this in one of several ways:

1. Change your interface configuration (/etc/network/interfaces) to match the new ethernet interface.
2. Delete the Udev MAC address map (/etc/udev/rules.d/70-persistent-net.rules), reboot, and let Udev rebuild the map.
3. Edit the Udev MAC address map (/etc/udev/rules.d/70-persistent-net.rules) and map the current MAC address back to eth0. This is the preferred solution if you have multiple interfaces defined.

You'll probably need to reboot the VM after any of these changes...

Why use Spring Python and not just plain python?

I have bumped into articles and forum postings, blog entries, other blog entries, and yet more blog entries. In fact, while writing this blog entry, someone posed the question “what is the aim of Spring Python?” (Click and see my answer.) There are a diverse range of view points, and many in disagreement about the viability of DI in python...

What Every Developer Should Know About URLs

I have recently written about the value of fundamentals in software development. I am still firmly of the opinion that you need to have your fundamentals down solid, if you want to be a decent developer. However, several people made a valid point in response to that post, in that it is often difficult to know what the fundamentals actually are (be they macro or micro level). So, I thought it would be a good idea to do an ongoing series of posts on some of the things that I consider to be fundamental – this post is the first instalment...
