Programming skill can be developed only by thinking and practicing. At the initial stage, students need to code large number of smaller programs preferably in C language without using IDEs in Linux platform. Advantage for students: i) students get familiar with linux platform, ii) proficiency in using keyboard and typing ii) no distraction and they focus only on their code

To enable students to code anytime and anywhere, a virtual Linux machine has been provided from BIT Cloud Resources. The details are IP Address: ssh port address: 3322 username: enrollment number for first year students eg. 2019UIT1065, staff id for staff members eg. IT1025. password: dob in the format dd-mm-yyyy. Login is available for all teaching, non teaching and first year students of IT,CSE,ISE,CT,CSBS departments. You may connect to the linux machine through chrome browser ssh addon or putty client (windows) or linux shell prompt or windows command prompt
