Assam-Calcu  is an all purpose windows based programmable calculator developed using Visual FoxPro 6 platform. It is capable of performing simple to complex scientific and mathematical calculations within seconds and can also be programmed to to solve complex mathematical expressions like the The Morse potential energy function given below:

and other similar complex expressions.

It may also be easily programmed to run hundreds of calculation-steps in one go by using the innovative Re-run command. Assam-Calcu easily stands out as one of the most powerful calculator for windows out there, but the long learning curve and dull User Interface is its biggest let down compared to other alternatives such as HiDigit. Nevertheless I think Assam-Calcu is the best choice for dealing with complex and advanced technological computations but using it for for day to day simple mathematical calculations is too tedious or sometimes feels unnecessary. Operation in Assam-Calcu is done by the execution of a simple command-line (like, ‘Answer = 673*249655′), or  (”Answer=d*(1-exp(a*(re-r)))*(1-exp(a*(re-r)))” ) in later the variables in right hand side ie the variables d,a, re and r are predefined before execution of the command line. Assam-Calcu may not be as easy to work with as your typical calculator software but it is still capable and accurate enough like any other software of its kind. Another great feature worth mentioning here will be that you don’t need to retype the same command-line again and again for the next set of calculations because once you use a command-line the program stores it permanently and all you need to do is change the variables and re execute the command-line from history (ie by clicking on the get_old_comm button and selecting the desired command from the command list. Some of the best features of Assam calu are:

• 12-digit maximum precision
• Scientific functions (trig, stat, fin…)
• Re-run command ( to run multiple calculation-steps at once)
• Complex numbers support
• Custom constants and variables
• Undo/Redo and History of calculations.

These awesome features makes Assam-Calcu stand out as one of the most reliable scientific calculator for windows. But apart from these there are clearly some areas which it could be improved, some of the areas in which I feel it needs to improve are:

• A more user friendly and simple interface
• Multiple interface languages would be nice
• The help file is very confusing at times especially if you are not from a mathematical or scientific background ( help and tutorial should be explained with some appropriate screen-shots)
• A video tutorial would be welcomed
• Assam-Calcu for mobile phones would be hugely helpful.

F.E.A.R. Combat is a free multiplayer component from the original PC first-person shooter F.E.A.R which is undoubtably one of the best horror shooters ever. It is basically the multiplayer component of the actual game FEAR, generously offered for Sierra. It’s a run ‘n’ gun kind of game where fast reflexes and shooting while running and ducking are the name of the game. This game blends great graphics, awesome gameplay and great maps all together in a small but great package. Another great thing about it is that it will let you play against the owners of the retail version of F.E.A.R. as well as the other F.E.A.R. Combat users. Internet is already flooded with tons of free to play FPS and other shooters but be assured FEAR Combat is undoutablbly one of the the best looking free to play FPS out there from the acclaimed developers Monolith. The graphics, special effects, and physics are although dated for 2009 but are in-fact pretty awesome, unmatched by most of the free to play FPS’s out there. Please visit www.joinfear.com to register for a required F.E.A.R. Combat authentication key. The download is around 1.8 gigs and the minimum specs for the game are pretty much same as the original shooter FEAR.
