It had been snowing without break from Monday evening till today morning, with an estimated 10 inches of snow or so. It's white everywhere - winter wonderland! And, to top this, there was an earthquake starting in Chicago at 4 am today. (source)




This is the frozen Chicago river, taken last Sunday when I went downtown with a friend (the UIC campus is really close to downtown)!

I was at a Google Android hackathon, organized by the Chicago Google Technology User Group, last saturday. I got a brand new Moto Droid for free, with a free 1 month Verizon connection. I later realized one of the teammates had registered but dropped out, and got the additional Droid for Prabhu. He will be here for a few weeks and is arriving this weekend, and we're looking forward to some erm, "pair programming". I'm uber-excited about my new toy, as can be imagined :)




I was part of the SIGDROID team from the ACM group at UIC, and had a good time there. I mean, getting 2 Droids in a day is pretty neat news :)

Grad school rocks! It's mighty hectic, and a lot of hardwork, but is really interesting, and a fun way to learn. I'm doing my MS (Thesis) in Computer Science at UIC.

I am taking the following courses this semester:
(i) CS 401 - Algorithms I
(ii) CS 502 - Design and Analysis of Efficient Algorithms in Computational Biology
(iii) CS 594 - Field Computational Biology

The last two are project-based, grad courses. For CS 502, I am working with a student in the Bioengineering department here, and as of now am reading some really old papers (by Pevzner, Karp, Shamir and a few others) on the physical mapping of chromosomes. The initial lectures were on Molecular Biology, and stuff from high-school came floating back to mind - gene sequencing, splicing, mRNA, ... :)

My favorite is CS 594. It is a joint course being offered by the "Ecology and Conservation Biology" department at Princeton and the CS department here. The best part of the course (for computer scientists who do NOT have to do data collection on a daily basis:) was the field component, where all the students went to the Mpala Nature Conservancy in Kenya. I joined late and missed going to Kenya. Oh well! I'm working with two biologists from Princeton on a project involving optimization, machine learning and visualization techniques applied to problems involving weaver-bird nests. I spent the last weekend reading up on weaver-birds, and this is really fascinating! We have lectures in fields ranging from ecology and agent-based modeling, to optimization and network analysis.

My RA on the other hand is a return to theory. I am working on approximate privacy, and more particularly to the use of privacy approximation ratios (PARs) to game theoretic problems such as auctions and the Millionaire's problem. Approximate privacy is essentially a trade-off between perfect privacy and communication complexity. We are now focusing on "second price auctions" and "Millionaire's problem", and use tiling and stuff for this. More on this later.

So yeah, while it's really hectic, I'm also learning a lot, and am really excited about this semester.

I'm living on-campus in a two-bedroom efficiency apartment, and a small but cosy, comfortable and convenient one at that. I have a Malaysian-American house-mate and she's cool. I make it a habit to cook at least once a day, and we have a good time sampling interesting stuff. The other day, she gave me some steamed sweet buns filled with a sesame paste, that she got from Chinatown, and they were reminiscent of kozhukattais! This week was particularly amusing - I got some tortillas to go with some ready-to-eat gravies that I got from India, rather than make rotis or get them from some store, while she whipped out a packet of frozen "Pratas" (they were actually a cross between parottas and parathas) that she'd got from Chinatown! Talk about "fusion" cuisine!



That's a pulav Prabhu made when he was here ...



This is my handiwork!

I haven't been to a single Indian store, and am none the worse for it. I should maybe just check W.Devon out, sometime next month. I did check out some off-campus accommodation, tagging along with a few girls, and was shocked at the living condition of some students! I'm rather happy where I am, for now!

Since this is an urban campus, walking distance from downtown, there's so much happening! It's actually kinda awesome - I can use my U-Pass to get anywhere in the city, and everything else is close by!

While I was a little miffed about the dearth for FOSS stuff, I'm a lot more excited right now after joining the ACM and LUG, here. Had a great time with Android 101 at the sig-droid meeting this past Friday. I still am missing all the fun I used to have at FOSSEE, but with so much happening on-campus, am super-excited right now.

The weeks are getting better, now that a significant chunk of all the paperwork I had to do is out of the way. Some of the things pending are getting my SSN, and some tax forms. Coursework is going rather well, but things are still kind of rocky wrt my RA/Thesis. Those should, hopefully, be sorted out this week. I am really looking forward to one course in particular - while I can audit it, I'm not sure yet if I can get credit for it. Will see ...

So far, so good ... :)

New Jersey, and our first snow!

















With the dogs ...




Fondue party!










So, what else were we upto whilst there?

* Watch Avatar on 3D
* Watch District 9
* Went visiting on New Year's eve, and got together playing "Pictionary"
* Did a LOT of shopping (gearing up for winter in Chicago, etc.)
* Go play in the snow! Walking during a snowfall is so ... ethereal.
* Went to NYC again (this time to meet friends, visit the Museum of Natural History and Strand Books:)
* Hog on everything from chaat to pizza, and basically have a good time :)

When we decided that I should take up on one of my admits, and join grad school, Prabhu also decided to accompany me, help me settle in, etc. before returning to IITB. That was one of the best decisions ever - we've had such fun, together. So much so, we started planning his next trip here almost immediately. He's coming here next month, but that's another story.

I have joined the CS department at the University of Illinois at Chicago (UIC). We reached New Jersey on Dec 26th, spent more than a week (and a wonderful one at that) there, came to Chicago on Jan 4th, and Prabhu's now back in India.

A wonderful wedding-New Year gift to us (courtesy our friends S and A) was a trip to NYC - in particular checking out the Christmas windows at Macy's, Saks 5th Avenue etc., the Christmas tree at Rockefeller center, Times Square, dinner, the musical "The West Side Story" at Broadway, and returning home in a stretch limo! Some photos from that:




The gang in Manhattan, sans Prabhu (who took photos for me despite having his hands frozen stiff every so often - thank you! :)




Madison Square Garden!




The Empire State Building.




A Christmas window, at Macy's.




The Christmas tree at Rockefeller Center.




NBC




Times Square.




and ... lastly, Prabhu and I :)

Prabhu and I got married on November 22nd, 2009, and have had a lot of fun in the process, and before and after. It was rather eventful, exciting and whirlwind, and everyone including us had a gala time :)
And, surprisingly for someone who found the institution of marriage erm, strange (to say the least), and who didn't want to get married EVER, I'm rather happy and find it very enjoyable :)



The two of us, at the pre-wedding party.



A collage from the wedding party.

I realized on Oct 13th, 2009 that one's life can change in a matter of minutes, possibly seconds. It did for me. Two weeks later, I'm still surprised, but there has been an upward spiral of the time dimension with minutes of change, hours of change, days of change... collapsing into a lifetime of change.

I completed 3 months at IITB on Oct 16th, 2009. Three months of working with Prof.Prabhu Ramachandran. He is a dream mentor - I don't think I'll ever get a mentor like him. Ever. His students love him, those who work with him respect him and everybody who knows him adores him. I loved working with him, working with his handpicked team ... It was a dream run for me. We worked, played, laughed, discussed, argued, learnt, taught... He has his hands full with teaching, his PhD students, research, administrative work, MayaVi work, coding/development, the FOSSEE project, (almost every weekend's taken up) conducting workshops, delivering talks and a whole bunch of random stuff, despite which he would sneak a few minutes to play BZ Flag with the team, take us out for icecream and what not. He was never too busy for me.

I had told him even before I joined that I'll probably be around for a year at the most and I might be taking up my admit at UIC. The only thing he said was that the project needs me and even though he'll respect whatever decision I make, he'll tempt me into staying on. So here I was, almost 3 months later at odds with myself. The last few years of my life have revolved around me getting to gradschool, doing research. I had it chalked to the T. I had my admits. Then IITB happened and due to this and a few other issues I deferred one of the admits to Spring. I had/have funding in the form of an RA, so that was not a cause for concern. And now, my I20 is ready, documents are in place, and I need to schedule a Visa interview, almost set to leave in December. The question was, will I ever get another mentor like PR? I really didn't think I would. I would be throwing away quite literally the happiest times of life in pursuit of my dream. I suppose that's the way it is - no pain, no gain. He had scheduled a meeting with me to channelize my thoughts, to put various issues in perspective for me and to actually help me focus on research. That went rather well and at the end of I considered him not just a mentor, but a confidante and a friend, someone who truly cared for me and went all out to ensure that I follow my dream and do so efficiently.

So I told him. About my confusion and second thoughts on going to gradschool now. He got in touch with a few of his friends, and after much reasoning convinced me that I could go for Fall 2010. I told him only one thing - "I joined for the project, but if I'm staying on, it's because of you." He is one helluva mentor and teacher and I'd be foolish to discard "this" right now. As everyone seemed to be pointing out, the three months here have been the happiest in my life.

Then things changed. He started pacing. I assumed he was mulling over some problem and just sat down to work, fresh from a discussion with him, brimming with optimism and truly inspired. After long dragging minutes of restless pacing, he came into the cabin I was sitting in. He said he hasn't been sleeping well. I knew it - he was looking haggard, with dark circles, unlike his cheery, playful, carefree self. He said he hasn't been eating well. That was obvious too; he had lost a lot of weight over the past few weeks. He said, he can't stop thinking of me, that he has strong feelings for me. This from a staunch bachelor for whom romance, relationships and weddings were never on the cards. My mind was reeling. We sat down to reason it out. I raised an array of questions, still feeling rather dazed but sounding like the Spanish Inquisition none-the-less. He patiently answered all of them. By the time we parted that night, I had just said that I'd rather have him as my mentor and friend and nothing more. But I hadn't given him a blatant no or yes to his proposal.

That was just for context. Things started moving even faster after that. After a lot more talking, I agreed. He swept me off my feet, rushed me home during the Diwali holidays, met my parents, introduced me to his family, charmed everyone's socks off (especially all the grandmoms:) and basically led to a whirlwind romance and a fast but blissful courtship. Marriage was never on the cards for me. I am 22 years old - an atheist, who abhors rituals, symbolism, religion, marriages as an institution and a whole bunch of other things. But here is someone I want to live my life with. Ideologically we are extremes, poles apart, at some level - he's spiritual and religious. I am neither and actually used to hold anyone who was these things with contempt. Even before all this happened, him and my mom were the two people who I admired and had respect for despite their fixations to religiousness. That week was a daze - I actually had no sleep for three days in a row and maybe a coupla hours a day for a few days after that, and there were days when not one morsel could be swallowed. It was the best of times, it was the worst of times. Things are settling down now. We are really comfortable with and around each other. We have a lot of common interests but have inherently different personalities. I think that makes for a heady mix :)

So, I am in love. It's a heady feeling. Confusing, and frustrating at times but fun and happy at others. I still will be leaving for gradschool in the end of Dec or first week of Jan. Chicago it is. It will probably be a horrible few months, away so soon but every cloud has a silver lining - he will be traveling to the US a lot and we can grab a few weeks together every few months.

Thanks to kai_dranzer and nivedita_n for being so amazing over the past weeks. I am also grateful to Asokan Pichai, both families and everyone else for standing by us and lending counsel.

This is him:








This is us:




PS - Excuse the cheesy userpic :D

A few weeks ago I joined a bunch of friends and drove down to Aurangabad. With that as base, we visited the Ajanta, Ellora and Aurangabad caves, Bibi-ka-Maqbara, the Daulatabad Fort and a few other neat places around Aurangabad. It was a wonderful visit and I got to use my (then) new digital camera (I now have an SLR, courtesy a friend, to play with :), but was too swamped after that to put the pictures up.

I'll break the trip up and make posts based on the places visited. This one will have photos from/of the Ajanta caves.
---




First glimpse of the caves. The entry to the region of the caves is so erm, unassuming (for want of a better adjective) that it's almost like stumbling on them!





This is the river Waghur, a mountain stream weaving its way through the ravine. It was supposedly the water source for the Buddhist monks based there.





Yours truly.




One of the most famous identifiers of the caves - the painting of Padmapani





Wall mural in Cave 1.





Multi-storey caves.





The Buddha meditating, multi-storey cave






Decorative arches.





A Buddhist monk, praying.





He graciously agreed to pose, serene smile in place :)





View from midway





Bunks, for the monks





View from the other side.





Little piece of glass embedded in cement along the cracks in the caves. It is an indication that the crack is widening when the glass breaks.





A wall mural narrating a story. The white elephant is supposedly the Buddha, who taught the queen (who had sent huntsmen for ivory from the elephant) a lesson.





I love the way the translucence of the cloth around the Buddha is depicted.

I have a whole bunch of labels and filters in Gmail, and I frequently use multiple labels for individual email, tagged as is necessary and also to act as easy reference for me. For instance, suppose I have an email from (?:))/ on "The Simpsons", I would have used my "Groening", "Cartoons" and "Humor" labels for this. This leads to a problem when am referencing or searching for this particular mail. I am able to search under one label, say "Cartoon" which will list all 500-odd (say) emails with the same label but it would make finding the exact mail a big pain. Also, it would be far more efficient if there were some way I could select (say) a combination of labels and find the mails under them. I am pretty sure this would be a far smaller list - especially if the number of labels involved were more than two. As far as I am concerned, list size is inversely proportional to number of labels, for the latter being greater than 1.

I could type the following in the search box:
label:Cartoons label:Humor
... but there ought to be a more direct way of doing it rather than this; doing this on an email client like mutt might be understandable, but having to do this on Gmail is rather irritating!

I might be missing some feature of Gmail that helps do this and I am ignoring any results Google might throw up with respect to this. I could email Google about this as well. But I would like to know if any of you have encountered this, have torn your hair (I'd really like to know, if this happened:) or have any solution...

I also have a few gripes on "contacts" in Gmail but that will be another post.

I am on vacation now. A short one, but a vacation that is keeping me mighty amused. kai_dranzer was highly amused by all the hand-waving I was doing off late and sent me this surprisingly accurate summary of erm, my life :



On the plus side, everyone is supremely conscious of the fact that I'm out-of-town, and am still being pinged ever-so-often. :)

Another friend of mine has the following as his status message :
"Google wave accounts are on sale on ebay. Current running rate is 157.5 USD! #wtf (http://identi.ca/tag/wtf)"

Ooh, I am potentially rich by $150. But then I'd hardly consider auctioning myself - even though I've done zilch as a Google Wave developer! More amusement. Reminds one of the Big Bang Theory episode where Sheldon Cooper auctions his Sword of Azaroth on ebay (the video).

Kind of under-the-weather for a coupla days now - but then, laughter seems to be living upto its name :)

I will be in Bangalore from the evening of September 25th till the evening of September 28th, for PyCon India 2009. If anyone is interested in a meetup, or if we can organize an lj meet during that time, it would be great... Do let me know by leaving a comment/emailing me.

We left Bombay at 12 midnight by bus and reached the base of the fort around 0600 hrs. After a quick breakfast of poha and chai, we started climbing. Raigarh is said to be one of the capitals of Chatrapati Shivaji's empire and is considered one of his important forts, among the many forts he built strewn across Maharashtra. There are about 1500 steps, but a lot more walking/hiking is also involved. There are no steps for checking out the various areas of the fort though and there is plenty of treacherous trekking in slippery areas that is done, especially during the monsoon.

The climb up:































Inside the fort:


(The Temple of Shirkai Devi)



(The royal flag)



(Statue of Chatrapati Shivaji, one of the most revered kings of/in Maharashtra)






(Gateway to the royal Durbar, with the throne of Shivaji. What is said near the throne can be heard in the courtyard outside the gateway and vice-versa! The gateway is called the Nagarkhana Darwaza)



(The living quarters)















(All of Shivaji's forts are built on the principle of "accessibility for friends, inaccessible to foes". This one was no exception and it was claimed to be impossible to climb up in anyway except the prescribed one. As rumor has it, all this changed one night. Everyday the main gates to the fort closed at 1800 hrs to be opened only at 0600 hrs the next morning. A milk-delivery woman named Heera (this point is named after her) was locked inside the fort. She had a suckling baby in a village downhill and pleaded with guards to let her out much in futility. Finally she navigated her way around, reached this point and climbed all the way down, back to her baby. As the story goes, when the king found out that a woman managed to get out of the fort that was claimed inescapable, he honored her and named the route/point after her and went on to mount canons here and setup a watch tower.)



(I think this is the Ganga Sagar lake. Not very sure. But as legend has it, Shivaji's pattabhishekam was done using waters from here, which in turn contained waters from the rivers Ganga, Sindhu, and Narmada, among others.)



(This is the Bazaar Peeth or the market area. There are stalls on either side, and shopping can be done both on foot or on horse-back, with the construction done accordingly.)



(This is how an individual stall looks (now in ruins though). There are 3 partitioned areas - the first is the shop front, then is the storage area and lastly the living quarters of the shopkeeper.)



(This is how an advertisement of yore looks. As story has it, the name of a shopkeeper was Nagappa. In order to have an identity for the store and to advertise his goods, he engraved the symbol of the nag here, among other things.)



(Moi, standing in what is called Takmak Tok. This is where punishments were carried out - prisoners and offenders were rolled off this point. As legend goes, this was unused as far as punishments were concerned during Shivaji's rule!)






(The Jagdishwar Temple)



(The Samadhi (tomb) of Chatrapati Shivaji)



(The samadhi of Shivaji's faithful dog. If I remember right, it's name was Maghya. It is rumored that the dog died immedidiately after the death of Shivaji)



(A Shiv Sena flag. One thing I find irritating is the religious extremism of a majority of Maharashtrians! It's unbelievable, to say the least.)









(Tanks from the Barah Taki or 12 tanks area)



(A small temple near the barracks)



(The "Dhongri" group I went with)



(The Shirkai temple, again)



(The Maharashtra Tourism Development Corporation (MTDC) has cable cars ferrying people to the fort and back, and also have a resort of sorts on the fort)



(Some of us on the way up - my maternal uncle (mom's cousin) who cheerfully took me along is on the left, the one with the blue backpack)


---

Couldn't take a single pic when coming downhill. It was pouring and we had a tough but amazing time trekking down in the rain. Streams and waterfalls erupted seemingly everywhere from the rains - I slipped and fell and nearly got washed down with a waterfall once! :)

Some cobwebs :











Some slimeys :








A shoal of fish :





Some creatures great and small :

Just back after a two-days and two-nights trek in Raigarh, and more specifically, the Raigad Fort. I went with a Mumbai-based hiking outfit called "Dhongri" (meaning "hill", "hilly" etc.), accompanying a maternal uncle of mine who has been hiking/trekking with this group for almost a decade now.

Also, I got myself a digital (point-and-shoot - wish it were a DSLR :( maybe a year from now... ) camera. Finally. Panasonic Lumix DMC-LZ7. I had initially planned on LZ10 but the store was out of stock, and this was offered at more than 2k less, and offered me 6x zoom (higher than the LZ10 and moreover, one really cannot hope for anything more than 4x costing under 10k). I got the entire works with a 2GB SD, batteries and a pretty good charger for Rs.6300 which IMO is a steal! I got to play around with it over the trek, although the batteries were a pain - I got the camera about 3 hours before leaving on the trip, and had no time for charging. Thankfully, I was able to charge them after the hiking upto the fort.

Now for some pics. Posting in themed installments.

(Not putting them under a cut. Also, excuse the erm, horizontal tree - realized this only after uploading, and am too lazy to correct this.)

The flora of Raigad Fort:

A month ago, I felt like Lord Voldemort. The resemblance is uncanny especially if your luggage is in 7 different places.

Now I feel like Victor Frankenstein - having unleashed a (blogging) monster to the universe at large. My mom has made 3 posts under 1 hour. Pretty good for a beginner. But I'm guessing this is to be her weekly quota - but made over weekends alone.

And, like a few characters out of Robin Cook novels, House M.D. and Scrubs - was down with a viral infection AND a bacterial infection, whole of last week. Now enroute recovery (and happy about that, since the doc had threatened me with surgery unless am almost fine by tomorrow - now this play with tenses in the same sentence is darn interesting:) But what is worrisome is that my sister was also unwell for the past few days and today the doc apparently said that it would be better to have her tested for Swine Flu, since she's showing symptoms (including purplish fingernails!) She'll be tested tomorrow. We're more than a 1000 km apart, and she's also away from home... Poor her.

This has stimulated my already hyper-OCD about washing hands and feet, not quite unlike Sheldon Cooper from The Big Bang Theory, and oh yes, Monica Geller from F.R.I.E.N.D.S..

Bombay's humidity is a killer. I've been perspiring like Dudley Dursley in the Tropics, and George Costanza climbing stairs!

Now only thing left is to grow a head, have the largest ego in the universe, and become Zaphod Beeblebrox. Now that would rank high on the Infinite Improbability Drive. The best medicine for this would be to ask...Jeeves?

View from my erstwhile room at IITB's Main Guesthouse (Jal Vihar) - it's the Powai Lake beyond the fence. And this was actually taken from the window using my LAPTOP! :)

This is an excerpt from a mail I got from my mother today:

"I am using the net after a long time and I got to see a lot of missed mails. Anyhow, the internet and me don't gel together. I am using it now for putting up recipes for you and your friends, and all those going abroad hoping to cook with the help of the internet, and to satisfy demands for recipes from a whole bunch of people! Try them and if in doubt please call. As for the Kozhukattai, if it does not turnout the way you want you can always use the dough for amminikozhukattai. It is a bit complicated for a beginner. Good luck with the kozhukattais. Will put them up as and when possible in that blog which you created for me for posterity. Most of the time I cook with eye levels and reducing it to grams and cups is causing some confusion. Any how I will perfect it before you start your cooking..."

So here's another RBFM (Recipe Blog from Mom:) - Prabha's Kitchen. Welcome to it. My mom's a wonderful cook and there are numerous yummy memories of being with her in the kitchen. Anyways, as of now, she has put up erm, algorithms for instant Rasam powder, Onion Thokku, and a whole range of kozhukattais. Will be trying out the kizhukattais this weekend. There probably won't be any pictures to help, atleast for a while, due to various reasons. If any of you require any recipe in particular, let me know and I'll pass it on.

I was searching for something regarding the instrumental fusion band Oxygen and stumbled on this musicindiaonline page. And was surprised to find this phrase - "Karnataka, an Indian music NGO". nivedita_n - if you can and would like to, do try asking them to correct it to the obvious "Carnatica". Unless I'm missing something here...
