The futility of existence (and how consumerism solves it)

The world is way too random to plan anything long term. When insurance agents send me mails, exhorting me to think about long term plans, all I can do is smirk (and then delete the mails). If anything the year gone by has taught me, is that life is a chaotic process. I am well read on the topic of chaos, but to take a step back and see how it has played havoc with all of our lives, is enlightening at best and depressing at worst.

Jan 2020: Reports of a new virus making people ill start maing its way into western media

early Feb 2020: The virus has started making its way into other countries. Remember how media reported on the first few cases in every country? I can recollect the discussion around an infected woman who travelled to Dublin and then took a train to Belfast (or vice-versa). I remember the discussion around the son of a bureacrat who attended a party in London, got infected, travelled to Kolkata but failed to declare it to the West Bengal health authorities. Both the mother and son were villfied to no end in the media.

Late Feb 2020: We were asked to work from home and Ireland declared a lockdown. Remember the pitch fork battle fought over toilet paper in the aisles of Aldi?

March 2020: Every discussion was around Coronavirus. HR trying to uplift the spirit of all employees stuck at home through different virtual events. Piece of advice: Those events are fun when you do it among team members and not company wide. I don’t know who Elisa from Accounting is and I can’t be arsed to team up with her in a quiz with Amazon vouchers at stake.

April 2020: Reddit was filled with rants about how people were not following social distancing norms and how close to reaching the peak we were. If I recollect correctly, Ireland did not reach the peak until May. But more importantly, the radar project I was working, the project for which I moved countries, was cancelled and we were left in a limbo.

May 2020: More work from home, but now fatigue has started to creep in. I got allocated to a project in which I had no interest.

June 2020: Signs of unlocking

July 2020: Unlocking of Ireland started in phases. Finally I could get a haircut.

August 2020: Work from home continues.

September 2020: I needed a new job and started looking for one.

October 2020: Was busy with an internal conference at Analog Devices. Took my mind off the distressing state of affairs.

November 2020: Cases rising –> lets lock up people in their homes. Fuck civil liberties. We, the elite Government, completely mistrust the people and we have this inherent need to protect people from themselves.

December 2020: Accepted the job offer in England. Started going out with Ciara, probably the best thing to have happened to me in sometime.

Jan 2021: Started packing to leave Ireland. Meanwhile cases exploded exponentially.

Feb 2021: Left Ireland and came to England.

March 2021: Same work from home but in a different country.

April 2021: Unlocking of the new country, but what could I do with the new found freedom, besides getting a haircut? I am a loner deep down and changing countries frequently does not help.

May 2021: Got my first dose of vaccine. Ciara comes over.

June 2021: Back to being alone. Got my second dose of vaccine yesterday.

Could I have predicted any of it, or any of the insurance agents predicted it? I doubt.

But what has kept my sanity all these while? Amazon (not Amazon Video). I have bought so much of stuff over the last few months and it felt like the boxes from Amazon were the only thing I could really look forward to.

“Oh but your job is so interesting!”

“Boohoo. I have been working long enough to know it does not matter really.” I mean, sure, I love my job and cannot fathom doing anything else. But to be fair, my biggest motivation to keep getting better at my job is the moolah the experienced folks in my industry make. And the job security that comes with it. As easy it is to replace an experienced software engineer with a younger grad, it is hard to do that for an experienced circuit design engineer. Do you know why? Because industry does not share its knowledge with the academia (not that the academia is very interested either) and you cannot fire up an IDE to learn stuff on your own.

Its physically hard for me to type this out, but I am now a card bearing member of the great consumerism culture. Capitalism claims yet another victim.

Having money means I can overcome most of the problems life throws at me. But it also means I am forever beholden to a 9-5 job (Well its more like 8-6 for me with a half an hour lunchbreak). Sure I can risk starting my own business, and in the remotest possibility that I am successful, I can cash out and live the rest of my life out of that money. But then if you know me personally, I cannot live without a hustle, I thrive in high stress environments.

All that for Amazon delivery boxes to keep you company in your loneliest times.

“What about family? Family gives purpose to one’s life?”

Being an alone immigrant

People often envy the life I have lead; they have been fascinated by my story starting from my time in Bangalore to Belgium to Ireland and now to England. I like to think I am well liked, and as I have often mentioned countless times, things may not have always gone my way but I always have had the best people around me to help me out.

But the toll of such a life is tremendous and it is often lost on people who haven’t lead this life. And when the realisation dawns on me, it hits like a massive wave, and brings me to a borderline panic attack. Just to give you an insight, if I were to die right now, I don’t know if the news will reach my parents within 24 hours. If Jack, my housemate, is away on vacation, I doubt if someone will find me in a week. There is right now a restriction on passengers from India, so my parents cannot come. Even if the ban was not in place, they don’t have a visa. And the similar situation holds for my sister. The only hope for the repatriation of my dead body is probably Ciara.

Why such macabre thoughts, you may ask? I dunno; maybe it has its roots in the death of a few people close to my family in the ongoing COVID crisis in India. Recently I picked up a book on the IRA written by Kevin Toolis. The book was first published in 1995 and it is amazing how many top IRA members he managed to interview. The rebels were always aware that they could die the very next time they are on the streets, but they did not let that deter them. I am no revolutionary, but I think being surrounded by people who believe the same helped them get over the fear. I doubt how many of them would like to be lonely in their final moments.

Death can always be a moment’s notice away and once you are dead, do you really care what happens? Maybe not. But I don’t want to be alone in my final moments. Of course, I can be hit by a car and die on the road. Should I be just scared and not leave home?

The answer is no, you keep going. You sleep alone in your bed, staring into the ceiling. You ask Google to play soothing sounds but they don’t really fill the emptiness in your room, does it? It is particularly hard for people like me who are very picky of who we let into our lives. I live in a time zone that is (almost) midway between US and India. It’s early morning there and my friends are catching up on their last bit of REM sleep. It’s late evening in the states and my family is just returning from work or just about to prepare their dinners. Where do I fit in?

The COVID crisis has definitely not helped. Every major news outlet just pays lip service to the impact the lockdowns and restrictions have had on the mental health of the general population. But the effects of that are not immediate, it will take years for it surface. Somebody dying, well, it’s more immediate and does not bode well for a government seeking re-election. But then people refuse to take precautions on their own! It does not hurt to wear a mask, or to maintain safe distance. They need the government to impose strict lockdowns. I appreciate the model followed by Sweden, as controversial as that may sound. People have been empowered to make their own choices.

It’s not being easy away from family, acclimating to a new culture, to a new place. Every time I want to buy something huge, I would be like, “How long will I be in this place for? If I had to leave tomorrow, can I even afford to move all of this stuff back to India? Maybe it’s a problem unique to me who has changed three countries in as many years.

But then, as the night draws on, you decide that you have rambled enough. You try to get sleep in the few hours left before you need to start the drudgery to survive the capitalistic world. Nobody needs to know the story behind that smiling face.

The need for a new India

This is my take on the entire CAA/NRC protests ongoing in India and what it means to a non-resident Indian in Ireland.

Its funny how people fail to realize that countries are imaginary institutions with borders which are blurred at best. The entire concept (and by that I refer to its boundaries) of today’s India is very different from the British Indian Empire. But lets focus on the current definition of India. What does it mean?

I have been called an anti-national by many Indians. But for me the definition of Indians is the quite simple: follow the spirit of the Indian constitution. But isn’t that arbitrary as well? Probably, but being in a pluralistic country, speaking a particular language and following certain cultural practices can hardly be the definition of being Indian. And one of the spirits of the constitution is secularism. The preamble to the Indian constitution says just as much:

WE, THE PEOPLE OF INDIA, having solemnly resolved to constitute India into a SOVEREIGN SOCIALIST SECULAR DEMOCRATIC REPUBLIC and to secure to all its citizens
JUSTICE, social, economic and political;
LIBERTY of thought, expression, belief, faith and worship;
EQUALITY of status and of opportunity; and to promote among them all
FRATERNITY assuring the dignity of the individual and the unity and integrity of the Nation;

And secularism is a very important principle. It is what differentiates us from Pakistan which was formed on religious lines. We don’t discriminate on the basis of religion.

Sometimes people have asked me, “If your constitution is secular, why are some religions given the minority status?” It again comes back to the concept of “Justice”. We thrive on pluralism. If a particular way of life is threatened, and it does not impact the Liberty, Equality and Fraternity principles, we will try to protect it. In the 2006 Sachar committee, it was mentioned that the Muslims are worse off in socio-economic conditions than the Dalits. Of course, some people would then say, “Well its their fault that they have so many kids and that they don’t focus on education.” Just like it is the fault of the black people that they are still marginalized in the US and have a far lower socio-economic status than the other races.

What irks me the most about the Citizenship Amendment Bill of 2019 is that it violates the secularism principle of the Indian constitution. Secularism is a strong word which has formed the basis of this country. And the bill is an indirect attack on the Muslims in India. I strongly protest against this.

“But it does not impact the Muslims in India”. But it does. This is testing of waters by the BJP government to see how far they can get away with by attacking the Muslim community in India.

“But this bill is trying to protect the minorities in the neighboring countries!” First of all it is not. The amendment to the Citizenship Act will help approximately 30k people who entered India before December 2014 (as per the Intelligence Bureau). Second of all, if we are so concerned with protecting the rights of minorities in neighboring countries, why have the Act excluded the Rohingyas of Myanmar and Ahmedis of Pakistan.

“But you see the protests have become so violent.” Unfortunately, not every Indian is Gandhi. The Government rolled the dice first and a backlash was expected. If the Government did not see this coming, it was a big failure on part of the Government. Or maybe they did see this coming and wanted an excuse to paint all Muslims as evil. Amit Shah and Narendra Modi can be many things, but I don’t think they are so incompetent to not foresee the backlash from the Muslim community.

And then there is downright Islamophobia. Some friends have told me, “How can you not see the cancer of Islam spreading across Europe having studied in Belgium itself?”. Refugees fleeing war (which, by the way, could have been prevented had the liberals not stopped some of the Western European countries from intervening in the crisis in Syria and Yemen when it was in its nascent stages) does not really strike me as “cancer”. I have worked with people from many countries and nobody was as full of shit as people who make comments like these.

We need a new India or atleast an organization willing to work to build a new India. Without a new India, polarizing political parties will keep coming to power either at the state level or at federal level. And each time, they will wreak havoc. The new organization needs to focus on three things:

  • Social change based on data and statistics: This is taking a leaf out of Bill Gates’ work on eradication of polio. Data can give insights on how a particular section of the population is doing. We need to reach out to those communities that are marginalized and need to yank them forward. I am always scared that data can be manipulated to fit any narrative but we need to be honest about it.
  • Education: Modern education. Starting from bureaucrats to bank clerks to farmers, they need to be introduced to the latest in technology. This can be done through a PPP model. Focus on environment needs to be a key aspect as well.
  • Health infrastructure and health education: A healthy population equals huge savings in healthcare costs in the future. People in all sections of the society needs to be sensitized to the impact of food that they are eating on their health.

Story of daily passengers

So after a long break from studies and a lot of immigration woes later, I reached Limerick. Well, my immigration woes are still not over as they made a mistake with my GNIB card and I waiting for a new one.

One of the first things that hit me when I reached Ireland was how empty it seemed. Granted I did not fly into Dublin and my hotel was outside the city (in Raheen). But I think its way less densely populated than Leuven was.

The next culture shock was shops and supermarkets open on Sundays!! And the fact that supermarkets don’t close before 10pm on weekdays! I was absolutely delighted.

But this is not a travel blog. I don’t like travelling and hate it when people say their horizons are broadened when they travel. Fuck no. Its expensive (I am still middle class). And you see only the parts which the tourism department of the country wants you to see.

One of the things of setting into a routine is the regularity in the faces you see almost everyday. I take the 304 bus from Sexton Street just before 8am. On the second floor of the bus you see the same bunch of school-going teenagers jumping about. If you are lucky, you can also see a bit of parkour performance from one of them. Its funny until you realize they will hurt themselves one of these days. Then there is another teenager who carries what seems like a violin case everyday. She ignores the bunch of kids and their antics.

Then there is the green haired lady with a cat ear shaped headphones with the outer texture of a leopard skin. Then there are these two girls who get onto the bus everyday from William Street with a cup of Starbucks coffee and saying to one another, “Oh how I love coffee!”.

Every now and then I see a differently abled kid who gets into the bus from a stop on the O’Connell avenue. He seems like a good kid. I often feel for the parents of kids who are differently-abled. Its hard enough to manage a career with a normal kid and it is so much harder with a kid who has special needs. The constant worrying they have to go through every time their kids leave the home. A big shout out to them. The TV series called ‘Atypical’ captures brilliantly the struggle of a kid with autism and everyone around them as they go on about their daily life.

My return times vary quite a bit and unfortunately I have not captured a regularity in it. Also, I am typically on the phone with my parents or my girlfriend on my way back.

One of the frosty mornings in Limerick

The frost covered mornings are often a beautiful sight. The weather varies quite a bit here. One day it can be freezing, the next day it can be rainy and 10 degrees Celsius. I always get down at a stop called Avonmore Road and walk to my office from there. The bus takes a diversion of 3kms just before my office. I find its better to just get down at Avonmore road and walk the rest of the path to my office.

And everyday, the same set of technicians who work nearby get down with me. And we have started to recognize each other and the usual nod or “How are you doing?” greeting.
(The Irish use “How are you doing” as a greeting. They don’t really expect an answer. Imagine that in Belgium! It will be paramount to a scandal to ask someone you don’t know in Belgium how they are doing.)

Hike in the fees of IIT and preposterous reasons for supporting it

So Mr. Ramgopal Rao put up a long post in Facebook mentioning his reasons for supporting it. It can be found at: https://www.facebook.com/rao.ramgopal/posts/10218188716681820?hc_location=ufi
Lets go through it one by one.

1. Many top universities in the world have strong Bachelors programmes and strong Ph.D. programmes. The universities which are running large masters programmes abroad are looking at these as revenue earners and charge a huge fee. The streams have also been modified and made contemporary like Cyber security, AI etc. In all top universities abroad, while doing Ph.D., many students get a masters degree along the way. This is how masters programmes have changed all over the world in the last decade.

Yes they do. Some universities in California do it. TU Delft and UTwente in Netherlands do it. But it does not mean its a nice thing. However there is a difference. Netherlands does not charge the high tuition fees from its own citizens or citizens of other countries in EEA (it makes sense as well; the people of those countries pay tax into their own system and its fair that they get a share of it). As for American universities, most do not treat its students as cash cows.

2. Students who come to the M.Tech programmes in IITs are not coming to become academicians. Those who wish to become one, can directly register for a Ph.D. All IITs allow a direct admission into Ph.D (with a high stipend and almost zero tuition fee) without M.Tech as a requirement, including the PMRF. Eventually, Ph.D. students registered in IITs will be able to receive a masters degree once they complete certain credits. Even if it is not so today in some institutes, I am sure, it will indeed become a norm eventually to make the Ph.D. admissions attractive.

Being interested in a PhD does not work like that. I was interested in PhD before I went for MS and then I realized that I am not. I liked working in groups but in PhD, you are expected to do things solely on your own. Also PhDs does not always mean a career in academics. A lot of highly qualified PhDs are required in the industry as well. Look up two new startups in Belgium: Pharrowtech and TuskIC. Both of them are founded by people with PhD degrees.
The way it works is you start doing your Masters, and then during your thesis, you will know if you want to continue in research or go to the industry. By increasing the tuition fees and forcing students who cannot afford to go the PhD way, PhD programs will see more drop out.

3. Students who join the M. Tech programmes in IITs are joining these programmes to find a job, which is fine. IITs therefore need to align their M.Tech programmes to the market requirements. Because of government freely giving fellowships, many institutions are running outdated masters programmes in streams which are not even seen as current by the Industry. In the current scenario, there is no strong motivation for any one to change. Many students take admission into the M.Tech programmes and over 50% of them quit as soon as they find a job. Among the remaining, many prepare for other competitive examinations and have no interest in what they are pursuing. Country’s precious Resources (IIT seats and government funds) are wasted in such a scenario with no benefit to any one. Today, we have uninterested students studying in outdated programmes which are completely disconnected with the market demands. Over 50% dropouts in masters programmes today in IITs only means that, students value the jobs they get after their B.Tech more than the career they can build with their M.Techs. How can we spend tax payers money to offer free education to them, when they themselves see no value in such an education? This is an alarming situation we have gotten ourselves into and obviously, a bit of a reset was needed. I am happy that Ministry and Council took such a bold decision.

If outdated coursework is the problem, then how does increasing fees help? If students don’t understand the value of doing a Masters program, its a different problem altogether. It means that the country does not give a higher preference to people with a Masters degree. And that is symbolic of a lack of highly technical R&D jobs that require an advanced technical degree.

4. If students are willing to pay 20 lakhs for an MBA degree in an IIM, they can surely pay 4 lakhs for a masters degree in IITs. Nobody drops out of IIMs since they see a value in IIM-MBA programmes. On the other hand, we see over 50% dropouts in IIT- M.Tech programmes. After the Council decision, since IITs now need to attract high fee paying students, I am sure, institutions will also align themselves to market requirements and will have a serious relook at the masters streams they are offering. This will bring in accountability at all levels. In the long run, the masters programmes will become contemporary and will train students for the jobs which exist in the Industry.

Business courses are so expensive because they require not just highly educated faculty members but also people who have a good clout in the industry. And to draw the latter talent, you need to pay them high salaries. Are they willing to pay the professors in IITs those high salaries?

And what is this constant talk about market requirements? The main focus of a Masters program is to teach students the basics and how to use them in a real life use-cases and some exposure to industry grade tools. The latter part keeps changing.

Masters program are not meant to teach students how to use the Eclipse IDE but how to take advantage of multi-threading.

5. IITs will focus on B.Tech programmes and Ph.D. programmes like what all research intensive universities worldwide do. Masters programmes in IITs will train students for jobs and those who are interested in academics, will switch over to a Ph.D. The top GATE scorers will still be offered admissions into M.Tech programmes directly as Teaching Assistants and will be offered fee waivers and stipend. However, the fee waivers and stipend will be linked to their role as Teaching Assistants. Others will get into these programmes paying a fee by taking loans, if needed. Since the programmes will get aligned with market requirements, they will be guaranteed a job and can repay loans.

Good researcher ! = Good teaching assistant.
And I studied in KU Leuven. It has been consistently ranked in the top 50 universities. It has been ranked most innovative university in Europe for three years in a row. Its also 600 years old.
And the attitude there is never that Masters program is for jobs. I am pretty sure its not the case anywhere else in the world.

6. The Council resolution also says that all needy students will be given fee concessions and scholarships similar to the B.Tech students. No eligible student in the B.Tech programmes has ever been denied admission in IITs because of her/his poor financial background. There is no reason to believe that this will be any different for top GATE scorers seeking admission into the M.Tech programmes. This is our moral and social responsibility

No, it just makes life difficult for students. It also puts them at the mercy of the administration. Education should be a right and not a charity.

7. The freebies that we have been doling out with tax payers money, to students who are uninterested and into systems which have become unaccountable, needed to stop at some point. Let’s not look at this from an individual’s perspective but rather see it in the larger nation building perspective. IITs are now taking loans from HEFA for their infrastructure. IIT Delhi needs to repay some thing like Rs. 580 Crores to Canara Bank over the next 10 years. Same is the case with IIT Bombay and others. There is a great need to increase our internal revenues.

Which means that these universities are not able to draw funded projects from the industry, which means that the ecosystem of doing state of the art does not exist in India or the quality is not good enough to command the top dollars that foreign varsities charge, which means that the faculty is not good enough. But of course, lets put the burden on the students.

8. IITs need to produce a large number of high quality Ph.Ds who can go out and build top class institutions, get into entrepreneurship and build research culture in our industries. We need to attract top GATE scores into our Ph.D. programmes through full fellowships and scholarships. The limited funds we have need to be diverted into these Ph.D. programmes. M.Tech programmes for a large number of GATE qualifiers need to be self funded (with a guaranteed job at the end of the programme) or sponsored programmes by industries. IIT Delhi has been successfully running for some time one such M. Tech sponsored programme in VLSI. This VDTT programme is entirely funded by semiconductor industries. This M.Tech programme still attracts top GATE scores but with the fellowship paid by the industries.

Yes we need more of such programs but it does not mean that we make life difficult for all Masters students.

9. Industries need to take ownership of M.Tech programmes in IITs and not leave it to the government. It is in their direct interest. M.Techs have indeed played a significant role in building the nation by serving our public sector units and private industries such as TI, Samsung, IBM, Intel, GE, Micron and many many others. Time they start investing their funds in building these M.Tech programmes in IITs and also work with these institutions closely to make the M.Tech programmes relevant. The modified CSR rules also allow this now. We are more than eager to work with them. We can then use our limited resources for doing other things.

Educating people is in the interest of the country. A highly educated population means crime rates are lower, people tend to take better care of themselves etc.

And the reason these companies don’t invest in India is because they don’t yet see the value. Companies always do things that suits them. If investing in India means they will get the best, they would do it. If not, then they won’t.

Using thermal cameras for detecting water leaks

I came across a nice article where they talked about using thermal cameras for detecting water leaks. It instantly reminded me of the project I did as part of a course called Multimedia Technology and Coding. I was given to write an paper on thermal camera and how to use it to detect faults in thermal insulation. There was another part as well where we had to decide on what standards to choose to store the images.

Anyway, this article published in Electronics for you talks about using thermal cameras to detect faults in a swimming pool plumbing system. Typically, they would have needed to dig the entire pavement around to find which pipe was leaking. But instead they used a thermal camera find faults in the water plumbing. The sun heated up the pavements but water having a higher specific heat capacity caused some parts of it to remain slightly cooler. Using the contrast they could find the faults.

Nice use of thermal cameras.

One of the many signs of a slowing economy

So I came across this article in Times of India today. https://m.timesofindia.com/business/india-business/edu-loans-in-india-shrink-25-in-4-yrs/articleshow/69490291.cms

The article is basically a summary of the non-performing assets in the education loan sector of India.

As per the article, the highest portion of NPA is in the sub-4 lakh loan. These are the loans that can be given without any collateral. There can be two reasons why the default rate is the highest in this sector

  1. Because there is no collateral it can mean that the punishment for not repaying is not there and students don’t take it seriously enough.
  2. There are not enough jobs.

I think the last one is more likely. I have both ancedotal evidence and some statistics.

The ancedotal evidence comes from my friends who are trying to set up factories in India. Whenever they start the construction, they get a lot of requests from local people for jobs (one of the condition for being allowed to set up a factory is that they employ the local people). But it’s not always possible. They then demand that they get all their raw materials from the local “syndicate” which is just another name for a shop supplying raw materials for construction. These are typically run by local youths who are not employed.

And the statistics comes from the rumors of a report that unemployment is at a 45 year high. Of course, the government never let the report come out to the public (but will they publish the report now?).

The students who take the small loans are typically for courses like B.Ed, nursing or the many courses in technical training institutes. There is a lot of automation happening at the factory level.. Some people can argue that AI is going to take over these jobs, but honestly that wave still hasn’t come and the data is from the last 4 years.

The default rate in the higher loan amount sector is much lower. These are the ones for things like MBA and engineering courses in one of the better institutes. MBA and engineering graduates can still find jobs although the quality of the jobs and the life satisfaction from it is dropping fast.

Not everyone gets into Google or Amazon or Goldman Sachs or Morgan Stanley OR Oracle or Samsung.. There is a sea of smaller IT companies which are trying to compete with the big fishes. The big fishes are going to become bigger because they have the capital resources to invest into things like AI, which helps them grow much more rapidly than the smaller companies. It’s a deadly positive feedback.

In short, the data presented by this article paints a bleak picture of the condition of the youth of our country. And it’s the beginning of a long list of problems that the new government will have to address. Else, our country will be submerged into chaos.

Another week started, and about my internship at Nokia Bell Labs

And classes resumed, without much of fanfare. Nothing new there, except for the thesis. I have never been so lost in my thesis. Also I had to finish my report about my internship at Nokia Bell Labs. It kind of sucks because we are graded on our internship which means we have to write a report and make a presentation of the work that we did.

A typical internship is 6-7 weeks. 8 hours per day. So anything between 240-280 hours spent. Writing the report is another 10-15 hours. Lets take 10 hours. So roughly 290 hours. Another 5 hours for the presentation. So in all, we have to spend 300 hours on the internship and all associated activities. One credit roughly equals 25-30 hours of work. So 300 hours should be anything between 10 and 12 credits. But we are only given 6 credits. [Source: https://ec.europa.eu/education/sites/education/files/ects-users-guide_en.pdf ]

For me this is really annoying.

But lets talk about the internship. The people in Bell Labs are nice people. But the work I did there was more like research as opposed to actual analog design. Honestly, that is fine by me. I worked for three years in a major analog design firm and I have had enough of the “experience” in a huge multi-national company. But what I did not like too much about the internship was that the specifications were not well defined as the beginning. Which makes it really difficult to work on something. And I was sick as well, but I had to push through. It is something I did not let the people there see.

But I think the star of this blog was Brecht Francois. A brilliant guy, with a PhD in power amplifiers from KU Leuven (his guide was Patrick Reynaert who is the top authority on power amplifiers, especially in the mmWave domain). He understood the limitations, had good discussions and it was really nice working with him.

So will I ever go back to Bell Labs? Well yes, if I can get to work with Brecht.

Unfortunately, I cannot talk about my work there (for confidentiality reasons). A big shout out to Jie Yang who was also interning at Bell Labs and was from KUL. The only friend I had there really.

One year at Leuven

Note: I started this article way before 15th of September and took several days to write it.

Although I officially complete an year in Leuven on 15th September, I thought I might pen down a few lines on how my year has been now. I have been told that there are two ways to write a review: compare your experience with the expectation that you had set out with; or write your review completely disregarding the idea that you had before you embarked on the experience. I, however, believe that a bit of both is necessary. This stems from the fact that I am too young and too less traveled to form an accurate idea of living in a foreign country or study in a top ranked university.

Now to give some background about myself, and why I left a very high paying job at Cadence Design Systems or a job offer at Samsung Semiconductors to pursue a Masters. Back in 2013, when I got my job at Cadence Design Systems, I did not study much for GATE and rather started working on various university events. But, thanks partially due to luck and partially due to my excellent concepts in the subjects, I secured an all India rank of 46 in GATE 2014. Those of you who are familiar with it, would know that even a rank of 46 is not enough to guarantee a seat in the MTech programs (Microelectronics) either in IIT Bombay of IISc Bangalore. I had no interest to pursue a MS program in India. Plus, the team in which I got into at Cadence had some of the best analog design engineers in India.

Anyway, during my job, my colleague and a good friend of mine, Gunjan Mondal asked me to get a MS. I also talked to other colleague including Vishnu who told me, “If not anything, you will enjoy the two years. These jobs will always be there for you.” Sunil Rajan, another brilliant mentor of mine recommended the same, “See in a Masters you can work on one thing exclusively for one year; you don’t have to do half the crap that you do in the industry. You will learn a lot.” And finally my boss, SKG told me, “You are young. You should always chose a path where you learn the most.”

At the time I was confused between KUL (offered me a full tuition fee waiver), TU Delft (offered a partial tuition fee waiver and a part of the excellence scholarship) and UTwente (full excellence scholarship). They all told me, if money is not the constraint, go to KUL. And here I was.

I did look at the subjects that I will have to study at KUL. It had a lot of circuits (which was fine by me) but also antennas and EM propagation. I never took a formal course on electromagnetics in my Bachelors and it was kind of scary. (But I still read some senior UG level textbook while I was working so I knew it won’t be mighty difficult).

I remember the first class. It was by Patrick Reynaert. Design of Electronic Circuits. The course covered operational amplifier design. There was a project (to design and layout an OTA; I was kind of lucky that I was allocated specifications that was not possible to meet. When you have to prove that something does not work, you will have to put in twice the effort to convince someone and you learn twice as much). Prof. Patrick is an exceptional professor who really taught the students a systematic way to design most of the common single stage OTAs.

And then we had Design of Digital Platforms. The project was really time consuming and kind of difficult. I was lucky to have a partner like Luis Diego. He worked several years in the industry, and was good with Verilog and we managed to finish the project and get a decently high score. We had a completely useless partner in <<name deleted>> who never worked, lied and tried to manipulate. I believe that none of my batchmates who teamed up with him in different projects had a good experience. (Lesson:Always select good project partners!)

The most difficult course was Digital Signal Processing. The course material was hard, and the project was not hard but time consuming. But then when you saw the finished project, you cannot help but remark that it is indeed a good learning. We had to transmit an image (of the professor; but I also did the same with my girlfriend’s picture) using audio. The modulation used was OFDM.

There were other courses like Analog Building Blocks for Signals and Systems. It was a great course for two reasons:

  • One, you learned of the top level specifications of analog blocks, what it means and some of the skeleton architectures of the most common analog blocks.
  • The exercise sessions were really good.

There was also a course on transmission lines and design of microwave amplifiers. In the final exam, we had to design the matching network for a potentially unstable amplifier. Its taught by Prof. Bart Nauewelers who is really nice professor.

Exams in KUL are held in January (first semester), June (second semester) and August (re-takes of courses that you may have failed in the first or the second semester). The exam periods are typically hectic. Other than the usual exam time late night stories, the only memorable part of it was my bed broke. There is this supporting frame on which the mattresses sit, and one of the ribs snapped. I knew I could fix it through some duct tape and wooden beams. So I went to my landlord.

“Yes Vivek, how can I help you?”

“Umm, my bed broke.  I was wondering if you had some duct tape and a wooden beam to spare.”

“Atleast tell me the girl was blonde.”

Despite what a lot of people thought, it did not break due to any girl. But anyway it was fixed and the rest of exam period went without any misfortune.

The second semester was rather dull as I had to take courses which were not that interesting . This was partly because I had to take Dutch classes, which was held twice a week from 7pm-9pm. It meant that two evenings in a week were completely wiped off.  I liked computer architecture.(The TAs were really great). I liked Design of Analog Integrated Circuits. I sort of liked antennas. I hated EM propagation. Technology fr Microelectronics is a course that gets special mention.

I also became homesick during my second semester.

Although I thought the most interesting part would be the project where I had to design a DCF77 receiver, it turned out to be rather boring. I was responsible for the digital part and it was okayish experience. Towards the end, I looked forward to the sessions because there was one TA I really liked in particular and we got friendly.

A better experience was with the project on Design of Analog Integrated ICs. We had to design a variable gain switched capacitor amplifier. The TAs were nice and because they were all international PhD students with whom we could connect more, share our frustration of the lives in Belgium. See the thing about KUL is that the classes are really small (in number) and you need to kind of bond with the TAs to have a good experience. Having empathetic TAs help. International people don’t have a home they can go back to on weekends. They need these little anchors to help them survive KUL’s MSEE program. It is nowhere close to being easy. I became good friends with one of them (Dileep).

Anyway after my second semester exams, I had an internship at Bell Labs. Unfortunately, I cannot talk of the work I did there but it was really nice working with Brecht Francois. Brilliant guy. Overall, Bell Labs was a nice place to work.

I returned to Belgium last week, and I joined IMEC for my thesis. As of now I am enjoying it and I hope to do good work on thesis. Lets see how my second year goes.

Random Musings

Blok period, and all the contemplation that comes with it

One of the most interesting phases of student life at KU Leuven is the blok period. It is the two weeks before the final exam (we only have one exam in a semester anyway) where you try and go through the subjects that you did not go read the entire semester because you just hated them!

But anyway, blok period for an electrical engineering student is really crucial. Most of our time during the semester is spent on projects. (Electrical engineering projects are extremely demanding, but you go away with so much of knowledge!). And this really the only time we are left to study properly for the exams.

I ran into Sujoy, a post-doc scholar in the COSIC group of ESAT yesterday at the Carrefour market. He was the TA to a very interesting course last semester, ‘Design of digital platforms’. We were just normally talking when he advised me to diversify my courses (read: take more fundamental maths and physics courses) rather than take more and more circuit design courses. Any new research field or any new novel idea is really an implementation of the basics.

And today I was reading Antenna. A dreaded course. Dreaded because my basics in electromagnetics are not that strong because I never had a good teacher in my bachelors university. Then a thought came to me: I understand (for most part) the material that is covered in the slides. But, today if you ask me to design a point to point antenna, will I be able to do it? Honestly, no. Given a current distribution, I can use Green’s function to calculate the magnetic vector potential, and then use it to derive the magnetic and electric fields. And then derive the impedance. But that’s all in theory. I don’t think I am confident enough to be able to build an antenna. But then, I have been taught the basics of the mathematical tools to do antenna design.

And it hit me. If today, I am extremely good in electromagnetics, I can pick up antennas much more easily than the other way round. If I look at analogue circuit design, if understand the basics of electrical circuits and feedback really well, I can go ahead and design a circuit. I don’t need to know a hell lot about MOS or a BJT to begin with a synthesis problem. If I am good in mathematics, I can be good in algorithms. Case in point: I studied a lot of mathematics while I (used to) solve problems from project Euler. I came up with algorithms and the formal proofs of them from the first principles.

In Belgium, they focus a lot on the basics in the first years of their engineering degree. Those exams are hard. Only after the basics, they introduce them to ‘engineering topics’. This was never the case in India. The basic courses were too easy, and the teachers who taught those basic courses were from the Faculty of Science, and they could not give a shit about the engineering students even if they wanted. That really stunts the ability of future engineers to be able to solve synthesis problems. If you are smart, then analysis problems can always be solved. But to solve a synthesis problem, the basic mathematical and physics tools need to be sharp. This is clearly lacking in the Indian education system.

Ok enough rants! Let me get back to my books! *Fuck!*
