Steps:

1. Install IDE of your choice which makes you most comfortable (KDevelop or [Qt Creator](https://cta-service-cms2.hubspot.com/ctas/v2/public/cs/c/?cta_guid=6cb0de4f-9bb5-4778-ab02-bfb62735f3e5&placement_guid=9f6a2170-a938-42df-a8e2-a9f0b1d6cdce&portal_id=149513&canon=https%3A%2F%2Fwww.qt.io%2Fdownload&redirect_url=APefjpG2ilihA6LOJhlZxcCQpuJJ0voE14hyT028lfa-mg4DrkV50fcczix5kW1PmfaKAyrdshdmUrHo967sJYEXUJVOl7D3f007rBFKS0iWw8rxZbhGNznxNta8WtAdpzE06Tat6DaTX05qTWaQkqE1DXprGlYLlw_ptZMNBBdebRDoZhfmGot4ULAx7O3BR6dhmJBuRnxwKZaK4GNdhlR_No7-1eyYwo8TQ3tGB_kW2iURyuSt

I worked with Boost C++ Libraries in GSoC 2018 to implement new Astronomy Library in C++ using various Boost Libraries and standard libraries. Development of this library started from scratch in GSoC 2018 so only a part of this library is developed under GSoC and remaining development will be continued after GSoC.

Aim of The Library

Development of this library started targeting not only professional C++ developers but also to the scientists and physicists who are not professional programmers and are new to C++ language. So with simple APIs, this library will help non-professional programmers to dedicate their time more to the real work other than programming.

Astronomy Library will provide basic functionalities which are required daily in the astronomy like the coordinate system and FITS file handling.

Features Developed During GSoC

Threading is the main concept which every programmer needs to know to write a good program so in this tutorial we will build a stopwatch using threading. Please remember that this tutorial is meant to teach you the concept of threading and not how to build the stopwatch. Actual watches are made in a more efficient way than this.

Overview of task: The stopwatch will display hour, minutes and seconds. It will have a start and a stop push button. Once the clock is stopped and started again it will count from the beginning.

Prerequisites: Basic knowledge of QT class QThread

Steps:

1. Create a new Qt GUI project with dialog.

I worked with Boost C++ Libraries in GSoC 2019 to extend my implementation of new Astronomy Library in C++ using various Boost Libraries and standard libraries which originally started in GSoC 2018. The goal of the GSoC project was to bring this library closer to its first formal review for acceptance in Boost C++ library collection.

Aim of The Library

Development of this library started targeting not only professional C++ developers but also to the scientists and physicists. With simple APIs, this library will help users to speed-up their development process.

Astronomy Library will provide basic functionalities which are required daily in the astronomy like the coordinate system and FITS file handling.

Features Developed/Enhanced During GSoC 2019

What is squashing?

Squashing is a process in which we squeeze multiple commits into one pretending it is only a single commit.

Basically squashing commits means we are rewriting the history of commits to make them look like single commit.

Why squashing commits is necessary?
