Yaadein: Semester 4 (JU)

The fourth semester was the first of the three busiest semesters in JU. It was a almost a paradigm shift from the slow and tranquil life of the previous three semesters. It started in february 2006, but ended in april, and there were exams in may. This left only 3 months for classes, 12 classtests and lab assignments all packed together. To add to this, was the project guide selection, which turned out to be a huge drama.

One of the earliest memories of this semester was that of one morning, when I, along with debarshi, anirban and haimasree went towards the Arts and Science section of the university. Debarshi needed to collect a form regarding some french class he was attending. He went to the Arts department building, while I sat near the building gate with anirban and haimasree. Whenever some girl walked past, haimasree would ask me whether i liked her or not. Earlier in the first semester, when dripto frequently asked me these questions, i got highly uncomfortable and tried to move away. But on this day, when haimasree did the same, i thoroughly enjoyed it, and became aware of the change which 1.5 years of college life had brought about in me.

Sayan, i have mentioned in earlier posts, was highly focussed about Ph.D. in USA. But in this semester, he also started preparing heavily for GATE, even though that was still two years away, and we had hardly studied much Computer-Science related subjects. But he selected Automata Theory and Discrete Maths, and started studying them and practising problems. Souri had got a collection of previous years' question papers of GATE, and Sayan started solving them. I particularly remember one day, when I found myself with the geeks of the class-namely sayan,swagato,arpan, souri and shibasis, engrossed over those questions. Sayan started singling out the questions related to graph theory, discrete maths and automata theory, and solved them before I could understand the questions. I  was shocked to see what was going on, since my own plan was to appear in GATE after two years. I panicked and started studying automata from that semester. Although i did not particularly like the subject, by the end of the semester had picked up a reasonable understanding of it.

Students are required to do a project in their final year, but many students start working in the third year itself. In this semester, we were taught digital logic by Prof PK Das, who taught particularly well. He ran the Center of Mobile Computing and Communication (CMCC) of JU, where some of our seniors worked. Some of us, including myself, had a fascination for working with PKD sir on this topic. Now PKD selected students on the basis of an interview and CGPA, and there was a heavy demand for him. 12-14 students approached him, including some of my close friends- arpan, souri, haimasree, debarshi and arijit. He asked us to organize ourselves in groups of 3-4 students each, so that he could interview in groups rather than individually. He asked us to study the fundamantals of Java and Linux for the interview. Some seniors had warned us to prepare well. I had no experience in either of the two, but picked up books and read the introductory chapters. My group members were arpan and arijit. On the D-Day, around 4:30 in the afternoon, all the 14 students huddled into the CMCC- a small but air-conditioned, brightly-lit, neat and tidy room on top of the administrative building. After a long and anxious wait, PKD started calling the groups one by one. Our group was second to go in. PKD asked some questions about java and linux, we answered whatever we had understood by our one-chapter reading. I don't remember any of his questions or our answers, but the latter ones must have been very weird. We were very tense after the interview, but after a couple of days he put out a notice stating that all 12 of us were selected except for Pramit and Ankit, who had interviewed with him but voluntarily opted out as they wanted database-related projects.

The above two incidents added to the tension of the anyway overloaded semester. To relieve myself of this tension, i often used to wander about the building during the free periods. It was a huge building consisting of two wings, connected at the second floors by a narrow hanging passage. The main building was 8-storeyed, and housed the Computer Science, Electronics, Civil and Architecture departments. The annexe building belonged almost entirely to the Computer Science dapartment. Both the buildings were dark, old, damp, dusty and even filthy at certain places. However, I thoroughly enjoyed my solo strolls to every nook and corner of the buildings, every passage and staircase, familiarizing myself with the names of the faculty, the different labs, reading the paper abstracts and posters displayed at different places on the walls. I am sure I knew the buildings better than anyone else in the class. It was fascinating, and for me, the best part of the semester.

It is in this semester that most of us, including myself, opened our Orkut accounts. Very soon, Orkut was the main talking point in the whole class, along with the book Five Point Someone. Everyone took great care to fill up his own profile, and often read others' profiles in great details. Very soon, orkut had become an important mode of communication among us-as important as the telephone. In fact, in later semesters it became still more important, and it could be claimed that for many (or most) of us, the Orkut existence had become as important as the real-life existence!

Though the semester was hectic, the summer holidays in june were particularly refreshing. It was the best vacation I ever had in my entire student life. The days were magical at home- the hot, sunny afternoons, the beautiful "Chand Sifaarish" or "Tu hi meri" playing on Red FM or my favourite Radio Mirchi, and the world cup football! After reading Five Point Someone I had become inspired to think beyond books and exercise problems and try something innovative- and I started to design various digital electronic circuits and implement them on a simulator. I had developed a deep passion for this, and also for networking, which was related to both PKD's project and our project in IIMC. Sometimes i would go to JU during the holidays, and met friends. Unlike students of other departments who hung out in canteens, the playground and the "lakeside" (a venue for lovebirds and smokers/weeders), the favourite hangout of some of my classmates was the Computer Architecture Lab where they surfed the web, and particularly Orkut. I went to this lab sometimes for some coding related to the IIM project, and had a great time mixing work with fun as many friends were around. I dare say, this was the best time for me in JU.

Yaadein: Semester 3 (JU)

This semester started in late august 2005, due to the delay in the previous semester caused by the Semester Boycott. The earliest memory of this semester that I can recall was that of the first day, a particularly cloudy day, with me, Dripto and Souri sitting outside the department below the Jupiter Building and discussing an Ashes Test match. Soon the classes started. In this semester, unlike the previous two semesters, we had interesting subjects. There was Data Structures, which was taught by Prof Chandan Majumdar (CM). He taught better than the previously seen JU teachers, and gave programming assignments which had to be done in groups of two. My partner was Arpan, a particularly "aggressive" (a term which i am in no mood to explain here ;-)) guy when it came to assignments and projects. His "aggressive" behaviour caused him to be disliked by many classmates, but i managed fine with him, at least in this particular semester. We implemented linked lists, stacks, queues, heaps and even b-trees and 2-3 trees - structures i have never used after that :-P. Besides there were the sorting algorithms. It was hectic, but enjoyable.

The other subjects included digital logic which was taught by DKB (never knew the full name). His teaching was quite horrendous, but i liked the subject. In fact I loved it. And I also loved the electronic circuits, 555 timers, schmidt triggers and all which were taught by Manojit Mitra- a part-time faculty in JU (actually based in BE College, Sibpur). Although I did not use them subsequently in any project, and gradually forgot them, these two subjects instilled in me a love for what I was studying- Computer Science and Engineering- for the first time.

A particularly interesting experience of my college life was the project at IIM Calcutta. It started in this particular semester, and continued for two years. It all started when Sayan mentioned to me, Arpan and Arijit about Debasis Saha, an ex-faculty of JU, currently a faculty in IIMC, was looking for 3-4 students for a project. At that time i had absolutely no idea of what exactly a project was- "a food or a hair oil". But Sayan and Arpan, the two guys who were always 1 year ahead of the others in class particularly in matters related to going to US for phd, convinced me and Arijit that this was very important for our careers. Shortly before the first visit to IIM, I fell severely sick, and the other three went there. I joined them in our second visit. We boarded a S-31 bus from the 8B stand, and went through unknown roads to an unknown place called Joka- at the southern extremety of kolkata-where IIMC is located. We entered the campus and went to a building called "CAM center"- to the first floor. After waiting for some time in a air-conditioned, tidy but empty lounge, the prof called us in. He gave us a paper - "A survey on sensor networks" to read and prepare a presentation on it for the next meeting. He also asked us to write a C program to display some circles randomly moving around and occassionally overlapping- each of which represented the range of a moving sensor node. For the next few weeks we were busy trying to make sense of the paper- most of it made almost no sense to us at that stage. However after going through Tanenbaum's textbook on Computer Networks, it started to make some sense, and I started liking it. However, soon after this meeting Sayan dropped out, and was replaced by Souri.

In november 2005, there were again prolonged strikes in JU- on an issue which I have forgotten now. It was at this time that I started making close friendships with other groups in the class. Beyond my established circle of friends consisting of Sayan, Arpan, Souri, Swagato, Dripto etc, I got closely acquainted with the group of Debarshi, Chiradeep, Pinaki, Haimasree, Sourav and Anirban. Debarshi, Chiradeep and Sourav were computer-addicted, technology-obsessed guys, but all of them were nice and jovial. Pinaki was a peculiar character -a bit rustic in taste but with a weird sense of humour that made him loveable. Haimasree was a nice and sweet girl, always keen to talk about romance and relationships. Their company induced a joviality in my own behaviour, which had probably been missing till then.

In a nutshell, the third semester was important to me because 1) it was the first time i learned to love Computer Science 2) i got a new circle of friends and a new dimension -joviality- was added to my character 3) the IIM project started and 4) It was a semester full of peace and tranquility despite the rather hectic workload - a peace that i never felt again in the subsequent semesters in JU. In fact the subsequent semesters were often marred by tensions, as will be described later.
