The FreeBSD Release Engineering Team has announced the availability of FreeBSD 8 stable release. The release comes with a bunch of features such as  network stack virtualization, Xen DomU support,  stack-smashing protection, improved ZFS v13, multicast updates including IGMPv3, a new virtualization container vimage, Fedora 10 Linux binary compatibility to run Linux software.
Thanks team.

The highlights in the 8.0-RELEASE are the following:
  • A new virtualization container named “vimage” has been implemented. This is a jail with a virtualized instance of the FreeBSD network stack and can be created by using jail(8) command.
  • The FreeBSD netisr framework has been reimplemented for parallel threading support. This is a kernel network dispatch interface which allows device drivers (and other packet sources) to direct packets to protocols for directly dispatched or deferred processing. The new implementation supports up to one netisr thread per CPU, and several benchmarks on SMP machines show substantial performance improvement over the previous version.
  • The FreeBSD TTY layer has been replaced with a new one which has better support for SMP and robust resource handling. A tty now has own mutex and it is expected to improve scalability when compared to the old implementation based on the Giant lock.
  • [amd64, i386] The FreeBSD Linux emulation layer has been updated to version 2.6.16 and the default Linux infrastructure port is now emulators/linux_base-f10 (Fedora 10).
  • The FreeBSD GENERIC kernel now includes Trusted BSD MAC (Mandatory Access Control) support. No MAC policy module is loaded by default.
  • The FreeBSD USB subsystem has been reimplemented to support modern devices and better SMP scalability. The new implementation includes Giant-lock-free device drivers, a Linux compatibility layer, usbconfig(8) utility, full support for split transaction and isochronous transaction, and so on.
  • The FreeBSD CAM SCSI subsystem ( cam(4)) now includes experimental support for ATA/SATA/AHCI-compliant devices.
  • The shared vnode locking for pathname lookups in the VFS(9) subsystem has been improved.
  • The ZFS file system has been updated to version 13. The changes include ZFS operations by a regular user, L2ARC, ZFS Intent Log on separated disks (slog), sparse volumes, and so on.
  • The FreeBSD NFS subsystem now supports RPCSEC_GSS authentication on both the client and server.
  • The FreeBSD NFS subsystem now includes a new, experimental implementation with support for NFSv2, NFSv3, and NFSv4.
  • The wireless network support layer (net80211) now supports multiple BSS instances on the supported network devices.
  • The FreeBSD L2 address translation table has been reimplemented to reduce lock contention on parallel processing and simplify the routing logic.
  • The IGMPv3 and SSM (Source-Specific Multicast) including IPv6 SSM and MLDv2 have been added.
  • The ipsec(4) subsystem now supports NAT-Traversal (RFC 3948).
  • The GCC stack protection (also known as ProPolice) has been enabled in the FreeBSD base system.
  • The supported version of the GNOME desktop environment (x11/gnome2) has been updated to 2.26.3.
  • The supported version of the KDE desktop environment (x11/kde4) has been updated to 4.3.1.


Physicists at the National Institute of Standards and Technology (NIST) have demonstrated the first “universal” programmable quantum information processor able to run any program allowed by quantum mechanics—the rules governing the submicroscopic world—using two quantum bits (qubits) of information. The processor could be a module in a future quantum computer, which theoretically could solve some important problems that are intractable today.
The NIST processor stores binary information (1s and 0s) in two beryllium ions (electrically charged atoms), which are held in an electromagnetic trap and manipulated with ultraviolet lasers. Two magnesium ions in the trap help cool the beryllium ions.
NIST scientists can manipulate the states of each beryllium qubit, including placing the ions in a “superposition” of both 1 and 0 values at the same time, a significant potential advantage of information processing in the quantum world. Scientists also can “entangle” the two qubits, a quantum phenomenon that links the pair’s properties even when the ions are physically separated.

“This is the first time anyone has demonstrated a programmable quantum processor for more than one qubit,” says NIST postdoctoral researcher David Hanneke, first author of the paper. “It’s a step toward the big goal of doing calculations with lots and lots of qubits. The idea is you’d have lots of these processors, and you’d link them together.

Release notes

MySQL founder is asking Oracle to give the MySQL to third party to avoid trouble with EU regarding it’s acquisition of SUN. According the press release on Michael Widenius’ blog below;

MYSQL FOUNDER OUTLINES SOLUTION:
INSTEAD OF LETTING SUN SUFFER,
ORACLE SHOULD SELL MYSQL
(ORCL, JAVA)

Michael ‘Monty’ Widenius says European Commission is “absolutely right to be concerned” about proposed merger between Oracle Corporation [ORCL] and Sun Microsystems [JAVA], nominates award-winning EU strategist to support the proceeding

Tuusula, Finland, 19 October 2009 — Michael ‘Monty’ Widenius, the creator of open source database MySQL and founder of the namesake company later acquired by Sun, today suggested Oracle should resolve antitrust concerns over its US$7.4 billion acquisition of Sun by committing to sell MySQL to a suitable third party. The proposed takeover has not yet been consummated because it is being investigated in depth by the European Commission as well as competition authorities in several other jurisdictions.

Widenius, who posted this press release to his blog, believes the EU’s antitrust regulator is “absolutely right to be concerned” and called on Oracle “to be constructive and commit to sell MySQL to a suitable third party, enabling an instant solution instead of letting Sun suffer much longer.”

The Finnish software developer and entrepreneur wishes Sun “all the best, but MySQL needs a different home than Oracle, a home where there will be no conflicts of interest concerning how, or if, MySQL should be developed further.”

MySQL was the only Sun business unit to be mentioned in the EC’s early September announcement of its in-depth investigation into the proposed takeover.

Acquirers commonly resolve regulatory concerns (before, during or after an investigation) by committing to divest problematic assets to a third party. By contrast, Oracle and Sun officials have thus far insisted they continue to seek approval of the entire transaction, irrespectively of Sun currently losing, according to Oracle, $100 million a month.

In order to support the regulators’ work on the case, Widenius’ new company, Monty Program Ab, works closely with Florian Mueller, a MySQL and EU affairs expert. Widenius said: “Florian gave MySQL strategic advice from 2001 on and was a shareholder until the sale to Sun in 2008, and with our support led an award-winning campaign against a proposed EU law on software patents. In August he helped us to demonstrate to the EC the need to investigate this merger and he is now on board again to meet the information needs of regulators, journalists and analysts.”

According to Mueller, “every day that passes without Oracle excluding MySQL from the deal is further evidence that Oracle just wants to get rid of its open source challenger and that the EU’s investigation is needed to safeguard innovation and customer choice. This is highly critical because the entire knowledge-based economy is built on databases.”

Mueller demands more respect for the EC: “It’s inappropriately arrogant for some interested parties to suggest that the EC has yet to understand the case. The EC is really doing a great job under huge time pressure.”

In what he calls “a solution-oriented information effort that is now necessary after other parties made public statements on the case in recent weeks”, Mueller announced that he will be available to journalists and analysts in Brussels (Wednesday, 21 October), London (Thursday, 22 October) and Silicon Valley (Monday, 26 October) to discuss the case.

In August, Mueller authored a position paper that Monty Program provided to the EC along with several other submissions. The latest version of the document was published today on the Internet.

Steve Balmer’s plans went really wrong with recent Linux patent auction. Instead of patents ending up with patent trolls, as Microsoft wished, AST acquired the patents, which was later sold to OIN, Open Invention Network. 
Up your Bolder :)
“Allied Security Trust is pleased that Open Invention Network had interest in acquiring the Open Source patent portfolio. OIN’s purchase ensures that these important patents will not be used by patent trolls or others seeking to disrupt Linux and the many companies and individuals advancing this important technology,” said Dan McCurdy, Chief Executive Officer of Allied Security Trust.
Following is the complete press release by OIN;

Durham, NC (September 8, 2009) – Open Invention Network (OIN), a collaborative enterprise that enables innovation in open source, today announced the acquisition of 22 Linux-focused patents that were marketed and sold by Microsoft. The patents were recently purchased by Allied Security Trust (AST) from Microsoft to ensure the patents did not fall into the hands of non-practicing entities (more information on non-practicing entities is available at http://en.wikipedia.org/wiki/Patent_troll, among other sites) that could seek to assert the patents against Linux products. OIN subsequently acquired the Microsoft patents from AST.

“Today’s announcement evidences OIN’s continued commitment to acquire patents that may be relevant to Linux,” said Keith Bergelt, Chief Executive Officer of Open Invention Network. “We are pleased to have purchased these patents and view this as a model of successful collaboration among defensive patent organizations that share a common goal of creating freedom of action for practicing entities across Linux and the broader technology sector. The prospect of these patents being placed in the hands of non-practicing entities was a threat that has been averted with these purchases, irrespective of patent quality and whether or not the patents truly read on Linux.
“Allied Security Trust is pleased that Open Invention Network had interest in acquiring the Open Source patent portfolio. OIN’s purchase ensures that these important patents will not be used by patent trolls or others seeking to disrupt Linux and the many companies and individuals advancing this important technology,” said Dan McCurdy, Chief Executive Officer of Allied Security Trust.
About Allied Security Trust
AST is a Delaware statutory trust currently with 15 member companies headquartered in North America, Europe and Asia. The Trust provides opportunities to enhance companies freedom to sell products by sharing the cost of patent licenses. To date, the Trust has invested $40 million in patent purchases over its 30 months of operations. Through such purchases, the Trust provides an excellent opportunity for patent holders of all sizes to generate a return on their rights by selling patents to the Trust.
AST is not an investment vehicle. Its purpose is freedom of operation and cost reduction. It generates no profits and does not engage in patent assertions against other companies. AST maintains a catch-and-releas; commitment that returns to the market in a timely manner patents acquired on behalf of Trust members after licenses are secured. The Trust also addresses the increasing need for innovative companies to defend against costly patent law suits. For more information, visit www.alliedsecuritytrust.com.
