m0n0wall
m0n0wall is a project aimed at creating a complete, embedded firewall software package that, when used together with an embedded PC, provides all the important features of commercial firewall boxes (including ease of use) at a fraction of the price (free software).
m0n0wall is based on a bare-bones version of FreeBSD, along with a web server, PHP and a few other utilities. The entire system configuration is stored in one single XML text file to keep things transparent.
m0n0wall is probably the first UNIX system that has its boot-time configuration done with PHP, rather than the usual shell scripts, and that has the entire system configuration stored in XML format.

VideoLAN – The cross-platform streaming solution
VideoLAN – The cross-platform streaming solution.
Overview of the VideoLAN streaming solution
The VideoLAN streaming solution includes two programs:
- VLC media player which can be used as a server and as a client to stream and receive network streams. VLC is able to stream all that it can read.
- VLS (VideoLAN Server), which can stream MPEG-1, MPEG-2 and MPEG-4 files, DVDs, digital satellite channels, digital terrestial television channels and live videos on the network in unicast or multicast. Most of the VLS functionality can now be found VLC. Usage of VLC instead of VLS is advised.

This sounds too complicated. The stream needs to be defined inside the app by loading a config file. It might be useful for certain applications however.

DSDT – OSx86
The Differentiated System Description Table is the main table in the ACPI part of a computer’s BIOS.
The Advanced Configuration and Power Interface (ACPI) defines a large number of tables that provide the interface between an ACPI-compliant operating system and system firmware. These allow description of system hardware in a platform-independent manner in ACPI Machine Language (AML).

PCIe, power management, and problematic BIOSes
As a result of the high clock rates used, PCI-Express devices can take a lot of power even when they are idle. “Active state power management” (ASPM) was developed as a means for putting those peripherals into a lower power state when it seems that there may be little need for them. ASPM can save power, but the usual tradeoff applies: a device which is in a reduced power state will not be immediately available for use. So, on systems where ASPM is in use, access to devices can sometimes take noticeably longer if those devices have been powered down. In some situations (usually those involving batteries) this tradeoff may be acceptable; in others it is not. So, like most power management mechanisms, ASPM can be turned on or off.

This might have something to do with the PCI ethernet card being shutdown on medusa — a problem which has only been resolved by not using the PCI eth slot on medusa’s motherboard.
Cisco plans virtual switch for Hyper-V in Windows Server 8
Expanding the ability of Cisco networking tools to work with Hyper-V could help Microsoft make its case that its server virtualization software is a viable alternative to VMware. The analyst firm Gartner has praised the Hyper-V technology and said Microsoft has the advantage of providing management tools that are familiar to Windows administrations, but that it has struggled to convert large enterprise customers from VMware to Hyper-V.

Researchers create stealth virtual machine that can run alongside insecure VMs
A team of researchers have devised a way to create an isolated and trusted environment on virtualized servers. Called the “Strongly Isolated Computing Environment” (SICE), the approach makes it possible to run sensitive computing processes alongside less secure workloads on the same physical hardware.
