Running WRF Model on Windows

Windows fun.jpg

WRF Model runs on UNIX platforms only. While this generally is not a problem for dedicated research or forecasting entities, for the casual user having access to only a Windows computer is faced with difficulties in trying out the modeling system. It is quite possible to install a UNIX-like operating system (e.g. Linux, BSD) alongside Windows, the technical details involved is enough to keep casual user from doing that.

With the introduction of a number of a number of Virtualization solutions by various entities another path has become open to try Linux tools on Windows. That is to use a Virtual_machine envornment that runs a Linux operating system within a virtual computer that is installed within windows. The beauty of the approach is the fact that the user does not have to be tech-savvy to use such a solution. Once a good setup is designed and implemented, it will run practically on any windows computer that is reasonably powerful. Read on for details ...

If you have ever tried to give away a reasonably complicated program that was written and compiled on windows to another user you should be very familiar with complaints of missing DLLs, and other dependencies and module mismatches etc., etc. These erros can manifest themselves in many forms (The procedure entry point could not be located in the dynamic link library; The application or DLL is not a valid Windows image or even Program too big to fit in memory.) This is particularly so if you happen to be developing with a complex build environment that is tightly integrated with windows system, like visual studio (I often use Visual C++ 2005/2008 express (free) editions and they create a lot of trouble in deployment!) read more...

Remote Editing in UNIX

Unlike Windows, UNIX computers were always meant to be accessed both locally (in front of the computer) and remotely (from somewhere remote). Even with today's high speed network communications, editing with a graphical editor like gedit over the network can be a tedious experience. You hit a button and wait ages for the user interface to be updated!. Of course if you are comfortable with vim or emacs editors which don't need any graphical interface, they you are fine. But for those who don't know these, there is WinSCP. Read more ...

Samba over SSH -- Opening Windows to UNIX safely and reliably

If you have Cygwin on your Windows machine, how to connect to a Samba share by SSH tunneling.

Your samba server may be behind a firewall that does not allow NetBIOS connections to pass. Or may be that your UNIX server is in Argentina while you live in Armenia -- it gives you creeps thinking how many people would be able to listen to your (unencrypted) data while its being transferred across!. A neat solution is to pass the communication hidden in Secure Socket Layer (SSH) communication. What's more you can automate the whole process rather painlessly, thanks to Cygwin! Read more
