SAP Gets Certified on Oracle Exadata Oracle :: Exadata Database Machines are now certified for SAP applications.


Despite the long-running rivalry between the two companies, SAP and Oracle announced a working relationship on Exadata certification a year ago.
SAP last year launched its own in-memory computing platform, HANA (high performance analytic appliance), and the company has also been pushing its Sybase ASE database as an alternative to Oracle for its ERP applications.
Oracle Exadata 2 is an in-memory computing platform for database and database-based applications. It provides high performance for both data warehousing and online transaction processing (OLTP) applications.

Fedora 13 nears end of life

Fedora Linux distros don't have a particularly long shelf-life. As a fast moving distro, the project doesn't have a long term support policy.

With Fedora 15 now out, the Fedora Project is closing the door Fedora 13.
"Fedora 13 will reach end of life on 2011-06-24, and no further updates will be pushed out after that time," Fedora developers, Kevin Fenzi wrote in a mailing list posting. "Additionally, with the recent release of Fedora 15, no new packages will be added to the Fedora 13 collection."

Fedora 13 was a notable release for several reasons.

The Fedora 13 release included a feature called System Rollback with Btrfs, which enables filesystem snapshots. Somewhat coincidentally, the next major release of Fedora, Fedora 16 is now scheduled to include Btrfs as the default filesystem. That's right from tech preview to default in three releases (roughly 18 months)


The release also provided new virtualization capabilities including Stable PCI Addresses and Virt Shared Network Interface technologies.

Having stable PCI addresses enabled virtual guests to retain PCI addresses' space on a host machine. The shared network interface technology enabled virtual machines to use the same physical network interface cards (NICs) as the underlying operating system. All stuff that is now 'old hat' for Red Hat and Fedora users, but it all debuted in Fedora 13.

Fedora since its inception has been a fast-paced distro, that's why Red Hat Linux was discontinued after all. Users, on the server and the desktop must update versions at least once every year or so, and hey if you know that up front, it's not a problem at all.

Mozilla Accelerates HTTP in Firefox 5

Firefox 5 is nearing completion and likely will be out next week. As opposed to Firefox 4 which introduced a new UI, tab panorama, jetpack, sync and apptabs, Firefox 5 sure does feel a bit 'light' on the big features side.

It does however have at least on amazing under the hood feature that will make Firefox 5 the fastest Mozilla browser ever. Unfortunately Mozilla's product people haven't chosen to productize the feature name but that doesn't make it any less important.

Sort Idle HTTP Connections by CWND - is a new Firefox 5 feature that I personally see as Mozilla's open web response to Google's SPDY, though they are a bit different. SPDY is focused on TCP optimizations while Firefox 5 is a bit more specific to HTTP.
"What really distinguishes different connections to the same server is the size of the sending congestion window (CWND) on the server," Mozilla developer Patrick McManus wrote in a bugzilla entry.
By reusing the largest CWND, the round trip time of an HTTP transaction can be reduced.
"This can reduce the round-trip time (RTT) of HTTP transactions by avoiding the need to grow connections' windows in many cases," Mozilla noted in a developer posting.
No this is not a replacement for SPDY, it's something else. But it is a step in the same direction. Namely improving the optimization of the transport.
