Making Standalone Web Apps with the Firefox Prism Extension
How to make web content into its own standalone application with Prism.
Realizing the promise of Apache® Hadoop® requires the effective deployment of compute, memory, storage and networking to achieve optimal results. With its flexibility and multitude of options, it is easy to over or under provision the server infrastructure, resulting in poor performance and high TCO. Join us for an in depth, technical discussion with industry experts from leading Hadoop and server companies who will provide insights into the key considerations for designing and deploying an optimal Hadoop cluster.

Built-in forensics, incident response, and security with Red Hat Enterprise Linux 6
Every security policy provides guidance and requirements for ensuring adequate protection of information and data, as well as high-level technical and administrative security requirements for a system in a given environment. Traditionally, providing security for a system focuses on the confidentiality of the information on it. However, protecting the data integrity and system and data availability is just as important. For example, when processing United States intelligence information, there are three attributes that require protection: confidentiality, integrity, and availability.

How to Build an Optimal Hadoop Cluster to Store and Maintain Unlimited Amounts of Data Using Microservers
Realizing the promise of Apache® Hadoop® requires the effective deployment of compute, memory, storage and networking to achieve optimal results. With its flexibility and multitude of options, it is easy to over or under provision the server infrastructure, resulting in poor performance and high TCO. Join us for an in depth, technical discussion with industry experts from leading Hadoop and server companies who will provide insights into the key considerations for designing and deploying an optimal Hadoop cluster.
Some of key questions to be discussed are:
- What is the “typical” Hadoop cluster and what should be installed on the different machine types?
- Why should you consider the typical workload patterns when making your hardware decisions?
- Are all microservers created equal for Hadoop deployments?
- How do I plan for expansion if I require more compute, memory, storage or networking?

Font preferences
Where can I find the "stylesheets" for editing font preferences of Prism applications in Linux? (Am using Ubuntu 9.10)

Hi There:
Thank you for this excellent tip. I used this to allow launching from WBAR in a KDE environment. This is to emulate the glaunch app in GOS, this puts the final touch on my home brewed distro based on PClinux0s 2009.
Thanks Again...

Can i download your videos? if there is any possibility then plzzzz reply me back.
It's Coming
We're working on the best way to roll them out. Every video also exists as an OGG file, we just don't have them linked yet.
Stay tuned!

Prism Rocks My Socks
When I first read about Prism, I thought it was kind of silly. Then I "refracted" a couple of Google apps through it and realized how useful the concept of standalone / single session web apps was.
Before using Prism, I would load six or seven Google pages in separate tabs ... not ideal. Now I have Prism shortcuts for Gmail, Google Reader, Google Calendar, Safari Books (awesome), and Trimet -- for tracking whether or not the bus is on time. :) Prism is especially useful when I need to log into multiple Google accounts throughout the day.
The downside? You can run into issues with plug-ins, which are kinda difficult to get running. And depending on the version of Prism you use, adjusting the font size can involve manually editing some stylesheets.
It what sense is the
It what sense is the resulting application 'standalone'? If I understand correctly, it still has the same dependencies as before, namely the remote web server and the Firefox web browser. Unless I'm missing something, all it's doing is launching Firefox and hiding some of the chrome.
Thought of another. :)
I also have a prism app for mibbit, loading the #linuxjournal channel on Freenode. :)

I use...
I use it to run Gmail as a separate application instead of a tab or window. With the addition of google gears, it makes for a fairly nice alternative to a standalone application.
Also, you can use to log into the same web application as different users. For example, if you use twitter for personal use, but also use it for business -- you can have 2 separate accounts with their own "application."
It's not Earth shattering, but in some instances it's really nice.
Oh, Pandora is another one I use Prism for. I think right now that's about it though.
