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 [[wikipedia:gedit|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.

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.) Cricket Worldcup Finals 2007How to listen to live Audio? Read More 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!!
Check here., UNIX file system permissions tutorialAccess permissions of every file and folder in a UNIX system is controlled by a system based on two identification numbers: user-identification number (UID) and group identification number (UID). Every file or folder should belong to a UID and GID. In practice is it hard to remember these numbers, so the accepted way is to map a user-name and a group-name to each number. In a typical stand-alone, UNIX computer, all UIDs along with these mappings are listed in the UNIX file /etc/passwd. Read more ... |
What is newRemote 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 wikipedia: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 ... Adding new editor buttons to Mediawiki[20:34, 9 September 2006 (JST)]
Depending on what type of article one is dealing with, there is always a number of specific directives that they end up using over and over again. Having these frequent tasks done at a click of a button saves time and increases the editing efficiency. Add Button Extension provides a simple framework to add custom buttons to Mediawiki editor.

Lately, there were some performance issues related to pathirana.net. Pages took increasingly more time to load and sometimes (when traffic is heavy) they even refused to load! I have decided its time to move internet service providers and just did that over the weekend. I was surprised to see how easy the entire process is. (Still it is not completely over, but things are working.) This experience may be useful for some others who, like me, are hosting small web sites as a hobby. Read more ... |
