CentOS now part of RedHat

The CentOS Project ( http://www.centos.org ) is joining
forces with Red Hat. Working as part of the Open Source and Standards
team ( http://community.redhat.com/ ) to foster rapid innovation
beyond the platform into the next generation of emerging technologies.
Working alongside the Fedora and RHEL ecosystems, we hope to further
expand on the community offerings by providing a platform that is
easily consumed, by other projects to promote their code while we
maintain the established base.

REDO : Backup & Restore make it easy!

Redo Backup is the most advanced recovery solution. It is small, fast, and very easy to use, even for everyday computer users.

	No Installation Needed You don't have to install Redo Backup. And you don't even need to have an operating system installed to recover. Just insert the CD or USB stick into your PC and reboot. Never reinstall Windows again!
	Boots in Seconds The system boots in about 30 seconds from USB, and all your hardware gets detected automatically. It uses minimal space and resources, the download is only 250MB, and you can copy it freely. No licenses or serial numbers!
	It's Pretty Redo Backup provides a point-and-click interface with network access and a complete operating system (via Ubuntu). Open other applications while your system backup is being transferred.
	Works with Windows or Linux Some backup solutions only work with Windows, and some only work with Linux. But with Redo Backup, any computer user can save and restore all machines with the same tool.
	Finds Network Shares Redo Backup will automatically search your local area network for drives to backup to or restore from. You don't need to know any details about a shared folder or network-attached storage device.
	Access Your Files Can't boot or log in, but need files from your PC? No problem: just pop the Redo Backup CD in, reboot, and you can copy your documents to another drive, a network-shared folder, or a USB stick.
	Recover Lost Data If you accidentally delete a file or empty your Recycle Bin, simply shut down the computer, insert the Redo Backup CD, and open the file recovery tool, which will undelete your files and save them to another drive.
	Easy Internet Access Is your computer broken, but you need Internet access to download drivers or read documentation? In about one minute, you can insert the Redo Backup CD, reboot, and be browsing the Internet.
	Factory Drive Reset Before selling or giving an old PC away, be sure all personal or business data has been removed by using the drive reset utility. This ensures that no private information is left on the disk.

OpenStack Havana

On October 17, OpenStack's Havana, the eighth release of this IaaS for public, private, and hybrid clouds, brings its enterprise customers several new improvements.

In the real world, OpenStack sees these features playing out in the following ways:

Application­ Driven Capabilities: OpenStack Orchestration is a template­ driven service for describing and automating the deployment of compute, storage and networking resources for an application. The new global clusters feature for Object Storage enables you to cut costs and improve performance by replicating and delivering data around the world, and the new QoS capability across Block Storage drivers allows you to guarantee performance requirements for an application. Docker support was also added to speed application deployment using virtualization containers.
Improved Operational Experience: The Dashboard user interface (UI) has also been improved. OpenStack Metering now provides managers with a single source of usage data across OpenStack services for activities like enterprise chargebacks and feeding systems monitoring tools.

More Enterprise Features: OpenStack continues to mature and support enterprise­ driven features such as end-­to-end encryption across all Block Storage drivers, Secure Socket Layer (SSL) support across all service application programming interfaces (APIs), new virtual private network (VPN) and Firewall-­as-­a-­Service (FaaS) capabilities. All users will be happy to see better support for rolling upgrades and boot from volume, which provides the foundation for live migration. Last, but not least, popular storage and networking providers continue to improve and write new plug-ins for OpenStack, making it easier for enterprises to work with their trusted vendors and take advantage of existing infrastructure.

How to create an encrypted zip file on Linux

The zip command line tool provides an encryption option. The encryption algorithm used by zip command is PKZIP stream cipher. The PKZIP algorithm is known to be insecure. Also, the fact that the password is typed and shown in plain text makes it even more vulnerable.

To create an encrypted zip file with zip:

$ zip --password MY_SECRET secure.zip doc.pdf doc2.pdf doc3.pdf

To uncompress a zip file that is encrypted with zip command:

$ unzip secure.zip
