Strawberry Perl doesn't come with SSH modules pre-installed. Here is how to insall C:\>perl -MCPAN -e shell cpan shell -- CPAN exploration and modules installation (v1.9304) ReadLine support enabled cpan> install Net::SSH Fetching with LWP: http://cpan.strawberryperl.com/authors/01mailrc.txt.gz LWP failed with code[500] message[Can't connect to cpan.strawberryperl.com:80 (connect: timeout)] As a last ressort we now switch to the external ftp command 'C:\WINDOWS\system32\ftp.EXE' to get 'C:\strawberry\cpan\sources\authors\01mailrc.txt.gz.tmp3104'. Doing so often leads to problems that are hard to diagnose. If you're victim of such problems, please consider unsetting the ftp config variable with o conf ftp "" o conf commit I would like to connect to one of the following sites to get 'authors/01mailrc.txt.gz': http://www.perl.org/CPAN/ ftp://ftp.perl.org/pub/CPAN/ Is it OK to try to connect to the Internet?

“A Big Ball of Mud is a haphazardly structured, sprawling, sloppy, duct-tape-and-baling-wire, spaghetti-code jungle. These systems show unmistakable signs of unregulated growth, and repeated, expedient repair. Information is shared promiscuously among distant elements of the system, often to the point where nearly all the important information becomes global or duplicated. The overall structure of the system may never have been well defined. If it was, it may have eroded beyond recognition. Programmers with a shred of architectural sensibility shun these quagmires. Only those who are unconcerned about architecture, and, perhaps, are comfortable with the inertia of the day-to-day chore of patching the holes in these failing dikes, are content to work on such systems.” —Brian Foote and Joseph Yoder, Big Ball of Mud. Fourth Conference on Patterns Languages of Programs (PLoP '97/EuroPLoP '97) Monticello, Illinois, September 1997   In a development team, people are focused da...

COTS, FOSS or FOSS+Support. Which one should you choose. The answer: it depends. (Surprise) Just because various software vendors don't invest in cross-platform software development doesn't mean you can't migrate to a new platform. COTS doesn't necessary mean vendor-locking, FOSS doesn't necessarily mean vendor independence and open standards. This is the nature of competition between Free Open Source Software (FOSS) initiatives and established Commercial Off-The Shelf (COTS) Software manufacturers. Executives are faced with immeasurable intangibles and difficult decisions for IT investment. There are many ways to crack the puzzle.  Here are 5 important things to ask yourself: Ease of Integration: Open Standards - do you need the solution to be flexible and have ease of integration? Flexibility and extension: Do you predict a need to extend internal components or extend the core product? Supportability - do you have internal IT operations that need to sup...

If you have a large new strategic initiative, how do you get buy-in, commitment, alignment, motivation and change management communicated. According to research led by Jim Collins in his book “Good to Great”. You don’t. In a large company like Kroger, the Level 5 CEO did not spend too much time to align 50,000 employees to the new strategy. Level 5 leaders simply don’t worry about that upfront, rather they depend on turning, what Collins calls the “Flywheel”: let the flywheel do the ‘talking’. Executing and then repeating success of a strategy and communicating that allows people to extrapolate – people want to be part of a winning team. Alignment, motivation, change and commitment takes care of itself. In my professional life, I have seen that happen – your strategy becomes everyone’s strategy! Everyone takes ownership and enjoy a shared success. It is possible, I have been part of it and recognize the ‘chemistry’.

Introduction Open source software, out-sourcing software development and contract programmers pose intellectual property theft exposure for companies today. More brick-and-mortar corporations are investing heavily in I.T. In-house software development teams come with additional responsibility and risk for the leaders. As more and more software products use component-based technologies there is an increased chance of using open-source products without understanding their licenses. Consultants and contract workers are hired for software development projects in addition to permanent employees to reduce time to market. Software development work is outsourced to other countries to cut I.T. spending. All these strategies have once common negative aspect – violation of intellectual property rights and subsequent legal action. In this paper, I explore these three strategies in brief detail and determine the risk and exposure relative to intellectual property violations. Intellectual Prope...

YouTube: 60 hours of video uploaded every 60 seconds. Google Search Index Size: 100,000,000 GB (and growing) GMail Active Users: 350,000,000 (and growing) Search Response Time: 0.25 seconds These numbers are astonishing. Reliability, Available, Scalable & Performance are Google’s primary quality attributes. Data – core business asset and few low hanging fruit, growth is faster than the ability to understand it, data capture is slower than the data getting generated, traditional BI tools can’t scale to capture it. Google has innovated Map Reduce, HDFS, HBase are used by Google to solve for these requirements.
