Life in These Times

I have made so many records during this lockdown and I’m breaking them as I write this post. For example, I haven’t stepped out of my house from the 21st of March, 2020. It is the 65th day of the record today and tomorrow, I will break it by making it 66. Even after a C-sec delivery, I tried breaking down the hold of orthodox thoughts (prevalent in my families) and went out to watch a movie before Sakura had turned a month old. Sometimes all this staying indoors for so long seems like one long dream and no one seems capable of waking me up. I have broken records of sleeping only for 5 hours, and sleeping for 5 hours on consecutive days, and so on. I have more respect for people who permanently work from home and manage kids and home all too well. Have realized that’s not my cup of tea and it definitely inhibits my thinking, productivity, creativity, etc.

People seem to have had a big realization during this lockdown: they have figured out the right/perfect/new ways to live. I did try to introspect many a times but didn’t reach anywhere. Just like my swimming classes which went too poorly, the only thing that I have been able to do is to kick and float through this lockdown. Some people have worked enormously during these times – the delivery people, the medical/paramedical staff, all the support departments operating on the ground and also those that have supported us online.

On the 9th of April, we had placed an order on Swiggy and on the 10th of April, we were surprised to read the following snippet of an article about “lockdown heroes” in ‘The Telegraph’:

The Telegraph: Lockdown Heroes

It brought smiles to our faces because (as you may have guessed) he was the one who had delivered those sweets to us the previous day and was featured in a newspaper but we were also saddened by the fact that we were his only customers that day. This reminded me of my Mother’s words who used to say (to impart some financial understanding to us) – “Most of the people work too hard for too little in this country”.

Here’s a fun little video and as Sandi Toksvig says ‘Be Kind’.

Sketchbook Ends.

After going through all the nine stages of disbelief, I have finally accepted that Sketchbook had ended. Seriously and utterly accepted that fact. So this is the final mention of Sketchbook v14 on this blog. The previous one is here. But this is the final one. Totally last one where I share some pages from the second half of the volume and my guesses at what they’re all about.

Sketchbook v14 p92-93

Juju, Nagisa and Sora are discussing the crawling curve of a caterpillar and comparing it with the Greek letter Ω. Also it seems that’s how a futon should look when used properly!

Sketchbook v14 p98-99

Sora and Ao in the kitchen with their food related antics. At least, Sora seems to be enjoying them.

Sketchbook v14 p110-111

Asaka is trying to showcase usage of a gourd that she made… As a container for a genie?

Sketchbook v14 p122-123

Just for the Hazuki’s serene pose and obviously, also for how a lint roller should not be used!

Sketchbook v14 p132-133

What little scenes of everyday life. Sheer brilliance! I’ll miss these in my everyday life. Also, this is from the last comic-strip-style chapter of Sketchbook. It is followed by 3 normal-manga-style chapters. The “first” page of the first such chapter.

Sketchbook v14 p140-141

Finally, Kei and Takane seem to have decided to join the Art Club, officially. This chapter then goes on to welcome them with a party where everyone tries to cook something or the other in the club room… I guess.

Sketchbook v14 p154-155

This chapter ends with Sora sketching “everyone” as the party ends with the usual approval from Ooba-senpai. The second regular-comic-style chapter is of course about the Cats. And I will leave the third chapter a mystery.

Well, that’s all. No mention of Sketchbook from now on here. Yes, not at all.

Work from Home…

In these depressing times, as we all work from home, humanity and sanity slowly slips away through our soapy hands.

In these tough times, as we don’t know what to prioritize, developers loose their valuable users/customers. I don’t know how true that last sentence is but I have definitely lost the one and only user (my superpartner) of my MATLAB program ‘AcBook’. But that doesn’t stop me from releasing its next update (officially at the end of this month but the installer has been already available for quite some time now).

In this release, I have mostly focussed on replacing the old exchange rates provider by a new one. Because the older one got a bit greedy and reduced the number of data requests one could make from 1000/month to 200/month in the basic free plan! Not that I was using the full quota. Even on a busy month, I don’t think I made more than 100 requests so 200 was more than enough given that nobody else is using the program now. But what really bugged me was that the rates were now updated daily instead of hourly! So if another provider could still support 1000 requests per month for free and the data was updated hourly, then why would I not transition to it. That’s exactly what I thought and did. In the transition process, I also learned that MATLAB can handle JSON formatted web replies quite well. That has made the startup time of the program a bit shorter and less error-prone as fewer file read/write operations are needed now. Also, made the ExChanger future-proof in case some currencies are added or removed by the new provider. Overall, I’m quite proud of the achievement and to give credit where credit is due, here’s a screenshot of the program’s login screen:

Life – T&C Apply…

What happens when one doesn’t write a post for a year or so? Out of the many things one forgets is the name of the app they have been using to compose posts. It took me 30 secs to remember what is ‘Windows live writer’ called today (It’s called ‘Open live writer’) as I went on to write a bunch of posts in the end of December to fill up the year’s quota of posts on the blog. I had taken my annual break of 2 weeks, gladly in the month of December and you would ask why? ‘Because I have my leaves accumulated’ is one of the answers but the obvious reason that everyone might guess is to spend time with the family. In my case, it was more specific than that – to spend time with myself. Out of the many things people say, one of the things they say right is that you never get that straight 8 hours of sleep once you become a parent. Over the course of the year, I have bought books which I have felt so keen about to read but either have not been able to start them or have left them incomplete. I had wished to spend the break time primarily doing that and have been able to read 5 books, not as many as I thought I would but happy to have a number greater than 0. I wanted to do more – like drive a car or join a Zumba class but where is the time.

Every person in this country who has a bank account knows about SBI and this year, SBI promoted its new online website named Yono. It was advertised using emails, newspaper ads, hoardings, etc. making sure everyone who used Internet banking went on to try Yono at least once. The first time I tried testing, I found something like the following while trying to fill in occupation:

Part of Card Application Form

We haven’t got to ‘E’ in this screenshot and that was the end of Yono for me. If anyone has created a longer drop-down list than this one ever in their life, please let me know in the comment section below.

I have lost a good number of senior family members in 2019. With each death, I have realized that life is not just short, it is too short, and it doesn’t matter if I live to the age of 94 (like my Grandmama who died this year) or to a mere 46 (like my Mother who died in 2010). Whatever that number be, life is very short indeed and it would be a total waste of my time if I do redundant things that don’t matter in the end, that don’t contribute to my prime goal at the end. My mother lived for a few years but wrote 27 journals to her credit. She wrote very fast because she had the capability of writing down things as people spoke. Sometimes I wonder if she knew what was coming along. Being with my mother taught me love, her leaving has taught me life. In general, the deaths have taught me to focus on important things, be mindful of the days that are not going to come back and do things that make me truly happy without bothering or causing trouble to anyone else and if there is a paradise, I wish I can be granted a place there and I so wish to meet some of the loved ones there, whom I have lost here, one time again, this one which would be forever.

On that note, I wish you & your family/friends a Great (replace ‘Great’ with any/all adjectives you like) 2020 – the start to another decade and hopefully one with a better climate, a bit more peaceful & safe and one which can make the world a better place to live for future generations to come.

Trip to the UK

This year, I travelled to UK in September for about a month and before the year ends, I would like to share my memories from the trip. I would like to start with the best part first. I travelled with my father and daughter. My father has been to China before this. When asked to describe the China trip in a few words, he said ‘Though the country like us has a lot of people, it doesn’t feel so in the public places. People are cleaning there all the time. They have a simple technique to pick up cigarette butts. The metro is just wonderful, but I so wish if the people there could speak some English’. About UK he said ‘the GPS is extremely useful, and I could read the directions very well for the first time on phone. There are pigeons and ducks everywhere. Everything though is of higher quality but very expensive. People are jogging/running all the time which explains the fewer Pharmacies. Our Railways follow the same system as theirs, it’s just that theirs looks cleaner’. It was the first trip outside India for my daughter. I have no idea how she would describe it. Maybe she can say something in future when she looks at the pictures. From what I could observe, she loved the green grass in parks with fewer children to share it with. She ran, slept and rolled over the grass, while she keeps on the lookout for insects here.

Green grass

We did some touristy things like visiting the London eye, Madame Tussauds, Buckingham Palace, Westminster Abbey, a lot of Parks like the James’s Park/Regents Park/Kensington Gardens/Greenwich Park and even visited farms for my daughter like Mudchute, and museums like the National Maritime Museum. It was quite a feeling to stand on the Meridian line and observe the home of Greenwich Mean Time at the National Maritime Museum. Sakura had the experience of traveling on a Buggy for a month. The first time she saw us preparing the Buggy for travel she cried but once she realized how comfortable it was to ride on, she used to just go and sit on the Buggy asking me to take her out on a walk. The weather was chilly, but the air was clean and none of us had to take any anti-allergens or medicines for cold.

I used to visit the nearby Supermarkets, Tesco mostly, to buy everyday stuff. On most of the days, Sakura sat on the Buggy while I picked up items and paid at the counter but one day she wanted to come out and check the aisles herself. Without me forecasting what she could do, I pulled her out of the buggy and there she was, wandering around me. While I moved to different aisles, she stuck to the one with chocolates and I didn’t mind her doing that till she was just being observant. It must have been a few minutes when I heard one of the shopkeepers asking me to check what my baby was up to. She had thrown a lot of chocolates on the floor and the moment she saw me, she started shouting, anticipating a not so pleasant conversation between her and me. Well… that was one embarrassing situation. I disliked myself for having taken her out of the Buggy in a Supermarket.

At a local park in London

We got 4 complete weekends, one of which we spent by traveling to a town named York. My father found a driver from Kerala, South India to speak to. In a 20 min Uber ride, the driver narrated his life in brief. That’s how simple I wish to keep my life too, one which can be explained in a few sentences, its goals and objectives clearly stated. He told my father that he loved his life in York as a driver. His wife who was a nurse had brought him to York. He has 2 lovely children and York has some of the finest schools in UK, something that he is very happy of. My father asked how life of a medical practitioner in UK was, to which he said “It’s tiring. The work hours are long, and doctors/nurses often work overtime because there is just so much to be done and written down.” My father was glad that the doctors are at least not beaten up like in our country. There are nearly 150 Indian families in a small town like York in UK and nearly 40 from just one South Indian state. One of the serious questions my father asked him was if he missed his home country to which he said ‘Not at all. The country and town have given him so much that he considers coming to York one of the best decisions of his life’.

We walked almost the whole town of York, covering the York city wall, York Minster, York’s chocolate story, York Shambles including the Wizardry shops, bakeries, open market, etc. We also met an elderly man who came forward on his own to take pictures for us as a family. Maybe he saw how I sulked at taking selfies/groupfies. People were extremely friendly; it seemed they had time to talk to strangers. It was quite nice to see a lot of elderly couple coming out and having breakfast together, chatting/talking to each other instead of using mobile phones. Street life seemed like a part of their life because by the time it was lunch hour, the streets were full of locals.

The highlight of my whole trip was catching a glimpse of Mr. Tom Branson (Real name: Allen Leech) from Downton Abbey. I saw him at the York Railway station on our return trip back to London and I think my eyes were wide open, but he happened to smile. I was so shocked to see him that I forgot to notice who was walking next to him, but I did notice that he smiled at his neighbor too as he walked along, almost saying something non-verbally in his smile.

In swing motion

The month flew by and all I’m left with now are memories, mostly beautiful and some funny ones. Now, if you wish to catch a few glimpses of my trip through my lens, please look at an album here.

Sketchbook Once More…

…Probably for the last time because of this post. As promised there, here are some pages from the last volume (14) of Sketchbook and my guesses at what is going on there.

Sketchbook v14 Pg6-7

Sora has fallen sick and expects to take medicines for a month!? So counts the pills in the bottle and makes sure there are 90 of them so that she can take 3 at a time? Maybe I’m as confused as Ao here.

Sketchbook v14 Pg16-17

The Art Students have gone fishing and they catch a fish that they don’t want… neither does the cat!

Sketchbook v14 Pg20-21

Ahh… the simplicity of Sketchbook that made me fall in love with this manga! Self-explanatory panels here.

Sketchbook v14 Pg42-43

Ahh… the complexity of Sketchbook that made me fall in love with this manga! Self-Bug-explanatory panels here.

Sketchbook v14 Pg58-59

Kate is again struck with some of the “idiosyncracies” of the Japanese script… Found some connection to Tetris?

Sketchbook v14 Pg68-69

Ahh… the simplicity complexity of Origami… Asaka & Sora have made aeroplanes that don’t quite fly but others have successfully made a lobster and a frog!

Sketchbook v14 Pg82-83

Finally, the long-awaited panels with Kuga and Tsukiyo. Tsukiyo seems to be fond of cats or is it the other way around? Also, is Kuga scared of black Cats?

CATS

Toddler Psychology

I wonder what goes in their teeny-weeny brains. When my daughter was in the womb, my friends and family requested me to listen to good music. They asked me to continue listening after she was born. I’m not sure what impact the music has had on her because I listen to random music – anything that I feel like. I somehow feel she is very kind and humble. Not sure again if that’s how all the toddlers are. The other day Sakura and I were in a close by market when she saw a man using crutches. A person like me is scared to watch a man holding crutches because it reminds me of pain. But Sakura, as her usual self, shouted ‘dada’ and then said a ‘hiii’. He smiled and waved a ‘hiii’ back when she told me ‘daaada’ by pointing fingers at him. Then she looked at him again when he had barely walked a few meters and said ‘tata dada’ (tata means bye and she uses these 2 words interchangeably).

A month or so back I bought her 5 pim-poms (candies) and she started to have one while we were returning from the market. When we reached our place, as soon as she saw the caretaker’s granddaughter in the parking area, she asked me to share one with her which I dutifully did. A few weeks later I was playing with her in the parking area as part of my everyday routine and Sakura saw that the granddaughter was holding a candy as well as a packet of chips in her hand. The girl first held the 2 items close to herself indicating her intention not to share and quickly found her way to hide the eatables under the sheet of the bed she was sitting on. Sakura looked at me trying to say something but did not. Instead she asked the girl to come play with her in a few words. I knew Sakura had connected the dots but she made me realize that it doesn’t matter. What people give back to you doesn’t matter. One needs to do things without expectations of something in return.

Things are not that rosy or enlightening all the time, though. She is quite passionate about teddies, to the extent that she is not willing to share the ones that are not even hers to begin with. We found that out recently while visiting a family gathering and she tried to monopolize a huge teddy at that house in the presence of (at least) two other kids. And witnessing such incidents – some sweet, some heart-warming, and some not so much – I have come to the end of 2019. So far, it has been a wonderful, wonderful experience watching Sakura grow. God bless her!

Inextensible and Infallible…

As mentioned here, I wrote a paper “rubbishing” another paper. We had sent its authors a couple of detailed emails about what we thought were problematic statements in their paper regarding the way they refer to our earlier (and related) papers. They seemed to agree with most of our objections and told us that they would fix them in version 2 of their paper. So far so good. We wait for nearly half a year and see no new version! Now, as Bill Bailey says: Contentment is knowing you are right but Happiness is knowing someone else is wrong!😊 So I decided to be both content and happy. I had already figured out something new about $\widehat{E}$ quivers which in itself wasn’t worth posting to arXiv. But with the “new” quivers in that paper whose twisted index hadn’t been calculated, I had something non-trivial to add to the literature. I did just that and evaluated twisted indices explicitly for some of those quivers because why not? After all, our claim was that the algorithm we use is exact & complete along with being simpler, faster, and easier to implement than theirs! Also, these new results confirmed the thing I had figured out about $\widehat{E}$ quivers too, so included the $\widehat{E}$ quivers in the appendix and called it a day after posting this paper on arXiv. After a few weeks of this submission, they updated their paper without correcting any of the problematic statements. What a bunch of %^&*! They even ignored this new paper of mine (which must have jolted them to action) because then they wouldn’t be able to write statements like “interesting possibility consists in ⋯ computing their topologically twisted index”, for their future directions.😁

Anyway, the title of this post is not regarding this paper but its predecessor. In it, we generalize the “well-known” toric relation (misleadingly called index theorem here) to a non-toric relation and give explicit examples in the form of $\widehat{D}$ quivers. The explicit computation requires additional new steps in the algorithm that had not appeared before in the literature because nobody had cared to look at the non-toric examples. Even after we had done so in a related context ages ago! People don’t even look at $\widehat{A}$ quivers (toric example) in general, they just keep repeating one ABJM calculation in different guises. And when something more than ABJM is done, these people go through all the emotional stages of being rejected. Basically, people are averse to the idea that their (or their colleagues’) ideas can be extended or improved. I have known this for quite some time but I witnessed this again in the referee reports and the few papers that didn’t cite this(these) paper(s) despite being aware of it(them)! This is like Yang & Mills generalizing Maxwell theory (non-abelian generalization of abelian gauge theory) but people deciding not to give any credit to YM because hey, $F_{μν}$ still looks like $F_{μν}$.

$\widehat{ADE}$ Quivers
