This folder, attic, contains code fragments. Like most attics, this attic needs a good cleaning. Some fragments are from the usual places on the web, cplusplus.com, stackoverflow, etc. Some fragments are DIY code written in class. Some fragments are as-is as found on the web while others are heavily modified to make work or add functionality. Some fragments are useful, some are not. Most fragments work, some don't. Notable Useful Fragments ======================== fastforward.cpp - a summary of OOP345. funcptr.cpp - examples of the many ways of passing function names to other functions: direct call, c-style function pointer, c++-style function pointer, function object (functor), lambda, bind examples of intersting functions to pass function to: thread, async, packaged_task sp?.cpp - smart pointer resources mi-*.cpp - multiple inheritance resources, clone+diamond problem theading?01?.cpp - threading101?.cpp - basic threading, mutexes - threading201?.cpp - futires and promises - threading301?.cpp - async, packaged_task - threading401?.cpp - how things were done before async + packaged task thread-*.cpp - cool thread code, such as thread pools ll*.cpp - linked list code moveSimple.cpp - move semantics stl-calc-*.cpp - postfix calculator using stl stack, list, vector, deque containers vectorchar*.cpp - how to make a string class mased on std::vector<char> dp-composite*.cpp - composite (tree) design pattern code alarmsetjmp.cpp + setjmp*.cpp - use alarm and setjmp to do interesting things swap.cpp - swapping data in place (without using a temporary) using xor and add operators. asmlist.cpp - how to generate an in-line assembler listing of the code generated by the compiler popen.cpp - how to start up a pipe to a program and read the output from the program folder threading-concurrency_in_action - pdf and sample code from Concurancy in Action book

Due to our interest in water conservation, we installed a rainwater harvesting system that collects water from the rooftop and stores it in a cistern. Rainwater stored is pumped to upper tanks in attic and it is mainly used to irrigate the crops specially when there is shortage of water. One problem that we face in long dry spells is the fact that cistern runs out of water. Thus we have to switch to a manual system to source upper tanks with well water. Every time this occurs, someone has to go to the attic, switch the water system and deactivate cistern water pump. When it rains again and there is enough water in cistern, the reverse manual process has to be taken, so it´s not practical. So we decided to make a system to monitor and automatically switch the upper tank source water between cistern and well water. Outcome- Here we have designed a prototype for monitoring the water level in the upper tank of household and also switching between the main supply and backup supply for constant water availability. This project is beneficiary as it not only helps to harvest rainwater but at the same time keeps a track of the water level in the house. The water stored in tanks can be used to irrigate crops, for gardening, washing of vehicles and flushing toilets. It is an efficient and economical project for fiscal use of water resource. Project Objective- To create automatic water source switching and monitoring system for rural areas. Project Conclusion- The earlier rainwater harvesting systems were feasible but they required much human effort and attention. Through this project we have aimed to simplify the human efforts by teaming up the traditional idea of water harvesting with the latest technology of Internet of Things. This innovative and modified idea keeps a track of the water that is stored during the rain showers in cisterns and also switches the supply during supply cut-off at adverse times.
