A few years ago Novell conducted an online public survey to determine which MS-Windows apps need to be ported on Linux desktop. Adobe Photoshop and other graphics application that user want ported to Linux. However, Linux comes with the sheer numbers of open source software projects produced by the community. You may overwhelmed by the choices available under Linux and not know where to begin. [click to continue…]
They say – there’s no such thing as a free lunch. But, Linux and FOSS software can be used to start, run and grow your business for, you guessed it, free. February survey of IT managers by IDC indicated that hard times are accelerating the adoption of Linux. The open source operating system will emerge from the recession in a stronger data center position than before, concluded an IDC white paper. Reducing costs and stronger interoperability with Windows were listed as the two top issues in a new survey of IT managers.

If your network is heavily loaded you may see some problem with Common Internet File System (CIFS) and NFS under Linux. By default Linux CIFS mount command will try to cache files open by the client. You can use mount option forcedirectio when mounting the CIFS filesystem to disable caching on the CIFS client. This is tested with NETAPP and other storage devices and Novell, CentOS, UNIX and Red Hat Linux systems. This is the only way to avoid data mis-compare and problems.
The default is to attempt to cache ie try to request oplock on files opened by the client (forcedirectio is off). Foredirectio also can indirectly alter the network read and write size, since i/o will now match what was requested by the application, as readahead and writebehind is not being performed by the page cache when forcedirectio is enabled for a mount
mount -t cifs //mystorage/data2 -o username=vivek,password=myPassword,rw,bg,vers=3,proto=tcp,hard,intr,rsize=32768,wsize=32768,forcedirectio,llock /data2
Refer mount.cifs man page, docs stored at Documentation/filesystems/cifs.txt and fs/cifs/README in the linux kernel source tree for additional options and information.
Interesting read and claim has been independently verified by somebody from Microsoft.
Greg Kroah-Hartman is a longtime developer of the Linux kernel, known for his work maintaining USB drivers as well as for packaging the SUSE kernel at Novell. O’Reilly Media recently interviewed Greg about his claim that the Linux kernel now supports more devices than any other operating system ever has, as well as why binary-only drivers are illegal, and how the kernel development process works.
The public perception of open source software is changing fast. French police force was currently deploying 50,000 Ubuntu-powered machines, while Spanish education authorities were rolling out 500,000 desktops with the OS. Hardy Heron also has improved support for multimedia, including photo editing, music sharing and video playback. It’s a favorite version of Linux both for specialists and one that specialists would recommend to a cousin, aunt or uncle who want to have a stable desktop internet experience. There are other versions of Linux that are better for a particular purpose – but Ubuntu strives to be a general platform that is secure and self-maintained.
Finally, both Red Hat and Novell is in total agreement – both of them thinks making money with Linux desktop is hard. According to Ron Hovsepian, CEO, Novell India Engineering:
The market for the desktop for the next three to five years is mainly enterprise-related.
As usual, I recommend Ubuntu Linux for both consumer Desktop and Laptop user:
- Ubuntu will always be free of charge, including enterprise releases and security updates.
- Ubuntu comes with full commercial support from Canonical and hundreds of companies around the world.
- Ubuntu includes the very best translations and accessibility infrastructure that the free software community has to offer.
- Ubuntu CDs contain only free software applications; we encourage you to use free and open source software, improve it and pass it on.
SAP and Intel , the world’s biggest makers of business software and microchips, will jointly offer servers pre-packaged with SAP software aimed at medium-sized firms, the two companies said.
SAP aims to provide customers with a 45% savings on implementation and a 25% savings on total cost of ownership over what they’d typically spend for a comparable hardware/software combo, said Jans Peter Klaey, president of global SME at SAP, in an interview.
The server is available in five Northern European countries and should reach 20 countries this year.
