whitepaper Cleartext Passwords in Linux Memory2008-07-26 Massachusetts Institute of Technology
  Upon examination, the memory of a popular Linux distribution contained many cleartext passwords, including login, SSH, Truecrypt, email, IM and root passwords. These passwords are retained by running applications and stored as plain text in memory for extended periods of time. The paper investigated the source of these passwords and presents a proof-of-concept method for recovering passwords from memory. The cold boot researchers demonstrated that memory is not as volatile as commonly expected, and that data from memory can be recovered with physical access to systems in a very short period of time. This has opened up a new class of attacks in physical IT security, and significantly raised the risk associated with cleartext passwords in memory.

whitepaper Using SELinux on an ICE-Linux CMS2008-05-01 Hewlett-Packard
  This white paper is intended for IT professionals interested in using ICE-Linux with Security-Enhanced Linux (SELinux) extensions enabled on Central Management Server (CMS) running Red Hat Enterprise Linux 5 (RHEL 5). This white paper includes SELinux access violations, policy Boolean variables, policy modules, and audit log analysis. With a combined understanding of these topics, people should be well prepared to write and install their own SELinux policy modules. They can then use these modules to enable ICE-Linux to monitor their environment as intended with the added security of SELinux.

whitepaper Business Integration Technology Case Study: Novus International2008-04-25 Business Integration Technology
  Based on decades of research and development at Monsanto, Novus International, Inc. was formed in 1991 and employs over 350 people in more than 20 countries. New business initiatives resulted in dramatic increases in the volume of sales orders and shipments in Novus' European operations. Although most of the 13 warehouses and 16 transporters wanted to communicate with Novus electronically, many did not have the required infrastructure. A change like this would require effort on their part to implement an integration solution. Novus hired Business Integration Technology to assist in the design, development and implementation of an integration solution for their Novus Europe team. Business Integration Technology implemented the Novus solution using an open source, standards-based architecture.

whitepaper GISP: A Transparent Superpage Support Framework for Linux2008-03-31 Institute of Electrical and Electronics Engineers
  Though all of the current main-stream OSs have supported superpage to some extent, most of them need runtime information provided by applications, simulator or other tools. Transparent superpage support is a further step, while so far there are only very few primitive attempts for Linux. This paper proposes the design of GISP (Global Information based SuperPage support), a transparent superpage support framework in Linux kernel. GISP adopts the basic idea of the reservation-based policy, and uses LMO (Lightweight Memory Object) and POPMAP (POPulation MAP) to manage the page allocation for applications. GISP could provide the core functions of superpage support while keeping the memory continuity by dynamic pages recycling.   
whitepaper Running Linux on the PlayStation 3: More Than a Toy2008-03-18 IBM
  The Sony PlayStation 3 (PS3) runs Linux, but getting it to run well requires some tweaking. In this paper, first in a series, Peter Seebach introduces the features and benefits of PS3 Linux, and explains some of the issues that might benefit from a bit of tweaking. When Sony first announced that the PlayStation 3 would be able to run Linux natively, a great deal of excitement ensued. Early on, it was a bit of a challenge to get Linux natively installed. The supported installer ran a custom script that hand-mangled a Fedora Core 5 or 6 install DVD into a runnable system with a special PS3 kernel. People put in hours and hours of effort to get other systems, such as Ubuntu, working.   
whitepaper Hosting Data Center Networking With Vyatta2008-03-10 Vyatta
  This paper will show how Vyatta open-source software combined with off-the-shelf x86 hardware can be leveraged to perform most routing and firewall requirements in the hosting data center at a fraction of the cost of closed proprietary systems. While proprietary networking equipment vendors have created discrete hardware product categories and price points based on arbitrary performance segmentation, open networking systems are proving that a single system can be continually upgraded to perform the same tasks. Vyatta solutions can be deployed at multiple points in the hosting data center from the backbone to the customer cage resulting in better performance and significantly faster Return On Investment (ROI).

whitepaper Extended Assortitivity and the Structure in the Open Source Development Community2008-02-08 Indiana University
  Open source software development represents the work of hundreds of thousands (perhaps millions) of developers around the world and is a critical component of many widely-used software products. Much of this development is self-organizing, taking place outside the structures of specific organizations. This paper introduces 'Developmetrics,' the application of Bibliometrics techniques to similarly characterize the artifacts produced by open source development (software). Similar cross-over analysis has been done before in the study of other self-organizing networks, such as the Internet. They use a standard Bibliometrics visualization technique to guide the discussion and they introduce extensions to concepts of network assortativity, node afference and node efference to accommodate network meta-data.

whitepaper Nswap: A Network Swapping Module for Linux Clusters2008-01-01 Swarthmore College
  Cluster applications that process large amounts of data, such as parallel scientific or multimedia applications, are likely to cause swapping on individual cluster nodes. These applications will perform better on clusters with network swapping support. Network swapping allows any cluster node with over-committed memory to use idle memory of a remote node as its backing store and to "Swap" its pages over the network. As the disparity between network speeds and disk speeds continues to grow, network swapping will be faster than traditional swapping to local disk. This paper presents Nswap, a network swapping system for heterogeneous Linux clusters and networks of Linux machines. Nswap is implemented as a loadable kernel module for version 2.4 of the Linux kernel.   
whitepaper Evaluating Open Source Software for Your Business2008-01-01 Pathfinder Development
  This paper looks at the strange world of open source IT decision making that can get in the way of good decisions. The exuberant IT manager sees open source like found money or a snow day; if it's free and good, why bother with the evaluation? Let's just use it. The cynical IT manager sees open source as a toy or a joke; people get what they pay for, so why bother looking at open source? Both of these attitudes miss the mark. When it comes to open source, people should evaluate it like any other software they are considering for their company.   
whitepaper Red Hat Enterprise MRG: Realtime Whitepaper2007-11-16 Red Hat
  Many enterprise workloads have extremely demanding requirements for determinism - to ensure predictable response times at the 20 microsecond latency level. The difficulty has been that until now, all realtime operating systems have been niche offerings - absent of any COTS (Commercial Off The Shelf) products. Red Hat is uniquely positioned to provide these capabilities due to its proven trackrecord of development and mainstream accepted Linux kernel realtime enhancements. In response to strong customer demand, Red Hat is productizing its realtime kernel in an offering called Red Hat Enterprise MRG, comprised of high speed messaging, realtime kernel, and grid cluster scheduler.
