Some older Linux kernels have a conflicting cache attribute bug that is exposed by advanced speculative caching in newer AMD Athlon(TM) and AMD Duron(TM) family processors including AMD Athlon XP, AMD Athlon 4, AMD Athlon MP processors, and AMD Duron processors model 6 and above.
This kernel bug usually shows up under heavy use of accelerated 3D graphics with an AGP Graphics card.

Embedded Linux is changing the face of embedded development and calling into question decades-old assumptions about how to build systems with real-time requirements.
The remaining majority of embedded applications benefits from responsiveness, but relies on throughput to achieve design goals -- "real-fast" or "just fast enough" suffices.
Linux, in its present incarnation (2.2/2.4 kernel derivatives), is not a real-time operating system by traditional definition or functionality.
Linux Journal recognized the importance of MontaVista's contribution to open source and embedded/real-time by awarding the 2001 Editor's Choice for Best Real-Time Tool to the MontaVista preemptible kernel patch, in particular for how it enhanced performance of multimedia clients on heavily loaded systems.

At last, Linux users have office software - word processor, spreadsheet, graphics, and presentation - which not only works at least as well as the Microsoft Office equivalent, but can also use Microsoft Office file formats, and is genuinely open source.
The starting point for the examples illustrating this document was a clean laptop install of RedHat Linux 7.3, so the examples show software installation from RPMs.

Describe a configuration allowing Linux hosts to establish a VPN tunnel to Check Point VPN-1 using IKE and IPSec.
If you have not done so already, you will need to install a copy of FreeS/WAN on your Linux host.
This product will allow Linux to support IKE and IPSec, and can be easily configured to interoperate with Check Point VPN-1.
This document will only address the necessary configuration to allow interoperability between S/WAN and VPN-1.
The default config file is /etc/ipsec.conf, so our commands were typed as follows: ipsec auto --add linux-fw1 and ipsec auto --add linux-encdom Below is a dialog of my session.

BOEBLINGEN, Germany, August 22, 2001 -- Hewlett-Packard Company (NYSE:HWP) today further strengthened its commitment to open source with several new offerings, including the first comprehensive security product for Linux-based systems.
HP has announced HP Secure OS Software for Linux and its HP Chai-LX embedded Linux software platform, expanding the company's comprehensive Linux offerings into two key strategic markets where customers are demanding reliable Linux solutions-security and intelligent devices.
HP also announced its intention to open source its ChaiServer product, unveiled a broad offering of manageability and high availability products for Linux environments, announced its Embedded Software Developers Network (devnet), and unveiled two new Linux-based workstations in Europe.

Second, I suggest reasons to think that peer production may outperform market-based production in some information production activities.
The first part of the paper expands the observation of the phenomenon of peer production to additional layers of the communications process.
The actual limitation on peer production is the capacity of a project to pool a sufficient number of contributors to make the incentives problem trivial.
This leaves the organization problem---how to get all these potential contributors to work on a project together, how to integrate their contributions and control their quality---as the central limiting factor.

Oracle has established a strong relationship with Red Hat, working closely with them to drive key enhancements into the Linux kernel, with the goal of delivering an operating system that supports enterprise-class functionality and mission-critical applications.
The thread-based model has limitations on 32-bit Intel Pentium-based systems because all the threads share the same 3GB address space for SGA, PGA, and other memory.
The Advanced Server 2.1 kernel allows Oracle to allocate and use more than 4GB of memory for the database buffer cache on a 32-bit Intel platform.
With Oracle9iR2 on Red Hat Linux Advanced Server 2.1, the SGA can be increased to a theoretical limit of about 62GB depending on the available RAM memory on the system.

The missing hardware is replaced by software -- Windows software, which presents a problem for Linux users.
In this case, you would re-format C: then run DOS' (not Linux's) fdisk program to make two partitions on C:, then reload all your Windows software onto the first partition.

Many people still believe that learning Linux is difficult, or that only experts can understand how a Linux system works.
Though there is a lot of free documentation available, the documentation is widely scattered on the Web, and often confusing, since it is usually oriented toward experienced UNIX or Linux users.
Almost as soon as a new piece of hardware became available, someone bought it and submitted it to the Linux test, as the system was gradually being called, releasing more free code for an ever wider range of hardware.

Cryptographic le systems store les and associated metadata only in encrypted form on non-volatile media.
We ensure that it is always present if the steganographic le system driver has been installed on this system, no matter whether it is being actively used or not.
Hidden les are stored in a very similar way to normal Ext2fs les.
To access a hidden le, we rst have to access the root directory of a hidden security level, then traverse the directory path to the inode of the le and nally access the data blocks referenced by the inode.
mount /dev/blockdevice /mnt/mntpoint -t stegfs \ -o btab=/path/to/btab In order to open one of the StegFS security levels to access or deposit hidden les and directories, we use the command stegfsopen /mnt/mntpoint contextnum where contextnum is either the number of the security context that is to be opened, which by default gives access to security levels 1 to contextnum,or zero if all evidence of hidden les shall be removed.
