A Productive Desktop Environment for Scientists and Engineers - Chapter IV is readyChapter IV is on how to create a simple and effective desktop database in order to keep track of everything! Read More Note: GFS, CPC and TRMM (GFAS) mapsAll of the maps in these pages should open a window with a larger image of the map, when clicked. However, it has been noted by some that this is not the behavior with Internet Explorer Browser. Please use Mozilla Firefox to avoid this error, until it is corrected. The free download of Firefox is available. (Read this.) GFS Weather ForecastsThe GFS model of NOAA, previously known as AVN/MRF, covers the globe at T254 (roughly equivalent to 0.5x0.5 degrees) with 64 vertical levels. The model is run every 6 hours, forecasting 16 days in to the future. More... New Section: Hydrology & Meteorology The real-time data is online again. Thanks for all who reminded me to get this done!!

What is newAsset management tools developed at UNESCO-IHEDuring the year 2008, a number of modeling tools related to Asset Management of Networked Water Utilities were developed by a number of students who completed MSc Degrees at IHE. In order to make the use of these tools as painless as possible, we have adopted (with permission) the Orange data mining tool developed by the Artificial Intelligence Laboratory of Faculty of computer and information science, Ljubljana University to provide an integrated graphical user interface to the set of tools.read more... Dependency Walker -- A remedy for distribution headachesIf 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 UNIXUnlike 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 reliablyIf 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 Real-time Weather Forecast for South-Western Sri LankaI have started running a daily real-time forecast for Sri Lanka with Weather Research and Forecasting Model. Using GFS global forecast (NOAA) as lateral boundary conditions it forecasts 48h into the future at 15min time resolution. Spatial Resolution is 3kmx3km. Read more ... |
