This demonstration proposes a method to improve performance and tolerance of network virtual block device "HTTP-FUSE CLOOP". HTTP-FUSE CLOOP is virtual network block device. It reconstructs loopback device from split block files on HTTP Servers. It has some benefits by comparison of other network block device. It doesn't require special server software. It can be implemented on normal Web hosti...

This tutorial will cover: An introduction to GStreamer terms, usage and the GStreamer pipeline model. Construction of simple pipelines using available GStreamer elements, building a video decoding pipeline Look at the requirements for various types of processing elements: Data sources, sinks, filters, converters. Development of a simple custom plugin for processing raw video frames Extending th...

This tutorial would be presented by Michael Still and Stewart Smith. MythTV is a powerful open source personal video recorder. It records television off the air, plays downloaded media files, DVDs, and audio files. It also includes a web browser, RSS reader, weather applet, and much more. In order to spend more time on interesting bits, there is some amount of MythTutorial homework to complete ...

Virtualization is not just a way to extract money from venture capitalists, it's also about cool low-level technical details. This talk will cover the fundamentals of virtualizing Linux on x86, using the in-tree virtualization hooks (paravirt_ops), with real examples from Xen, VMI and the in-tree toy hypervisor lhype.

Wouldn't it be great if you could make money by working with the software you love? Wouldn't it be fantastic to be your own boss, working with open source tools on open source projects, and doing it all on a schedule that you decide?Starting a small business of any description is a big leap, and most small businesses fail. Starting your own business to specialise in open source technologies is ...

Unlike PDAs, handheld gaming devices are extremely economic in their hardware, and hence notably cheaper and less powerful. We have finally reached the point where they are powerful enough to run a full GNU/Linux environment despite this. In this talk I will discuss the relative merits of running Linux on two handheld gaming devices, and developing for those devices from Linux on the desktop. T...

This talk will look at the different disk encryption mechanisms available today, and how they can be integrated in your personal, and work environment. Namely: disk encryption options available worrying about security, and encryption robustness weakest point of entry encrypting a separate partition making encryption as seemless to the user as possible (single password with pam) encrypting an en...

IO performance is one of the most critical aspects of a wide variety of systems. On the server side, IO bound workloads are plentiful, and on the desktop, IO latencies are often one of the most important characteristics of a responsive system. The problem with IO scheduling (like most other scheduling), is that there are no correct answers; or, at least, none that we can find in a bounded time....

"Screencasting" is a great new way to demonstrate your software to people online. Instead of just posting a screenshot, you can make a movie of your application in action so they can see the flow of your interactive elements, all the cool animations, or just how rocking your desktop really is. It's even better with narration!Software on the free desktop is making it ever easier to produce scree...

Telepathy is a communications framework based around D-Bus. The project defines a series of interfaces which can expose all of the functionality of any IM/VOIP protocol, implemented in background processes which maintain connections to the services on your behalf. Front-end processes (be they GUIs, console applications, bots, gateways...) can interact with these background processes to carry ou...
