Me falling..

Category: By AG
I'm listening to Roobaroo and Kase Sartil songs, the ones which I always listened for quite a lot of time now...lots of sentiments attached with these songs...the smell of AC air of summer in US, snowfall of December, Houston trip, movie night-outs, ... lot of things...its coming to me like a flashback. I'm just a day away from the day I awaited since the past couple milleniums... I know where I should be. I've missed my place like hell, and I now can't wait to see my dream coming true...I want to go home! I hope I hold up myself for these last remnant hours....like one of my friend puts it - its inexplicable and unbelievable I spent such a long time away from my home - and its not been any easy!

The Climax

By AG
Everytime I fly out of KCI, I think, "OK, now its the last time before I fly out for the des." But its just not happening, I think I'm being teased! But now just 6 days to go, I'm now sure, the next time I'II fly it would be for a land far far in the east...where I've been (senti-)mentally all the time. The climax is not far, but the times decided to run slow.

27 days to go :)

India Nite

By AG
I was as awful as I could..it wasn't the stage fear, it was the lack of practice. Can't complain actually, just had couple of days. And was difficult for a newbie like me who never performed in front of more than 4 people and had started self-learning just couple months ago. Played casio on around 4-5 songs in the annual program gathering of around 300 people that Indian Students Association arranged here at k-state on Sunday. I think I should often go to garage sales, from where I picked up this casio :)

SEA to KCI

Category: By AG
OSDI was fun..was a nice short break. Seattle is a nice little place. The return journey took my entire day, this happens when you plan a trip a month before :| After many people insisting, I couldn't afford missing visit to the Space Needle (wikipedia entry is better than the official site ;)) and the EMP (thats Paul Allen's another toy house, Experience the Music Project). Although I had planned to visit both, they are just side-by-side, I could only visit Space Needle and with around 45 minutes left to spare, the ticket vendor at the EMP generously advised me not to rush through it, as it won't be worth it. The architecture of the EMP is as crazy as it could be! Letting the EMP visit go, I wandered around more, collecting sovenirs and stuff.

I thought I was on track and on time. I didn't anticipated the time it'II take me by bus to get to the airport. I had to hop around to get to the airport, and boy, I now just have 30 minutes to take-off, and I haven't even checked-in! The guy making the boarding pass gave me a pale look and said, "Let me see if you're not too late." He checked me in saying, "This is the closest you could ever get! Run, and get checks done." I had to. The line for the check was tooo big (SEA is a small airport, smaller than KCI!) finally I got the checks done and it was 10 minutes to the take-off and I was still outside searching for the right gate. On finding it, the boarding pass checking lady saw me and stopped another guy entering the plane gate saying, "Another customer showed up." So close! Finally I got in the plane just couple minutes to spare, with the officer's words echoing in my ears, "this is the closest you could EVER get!"

Rest of the journey was fun, and now continental is on my "preferred" list of airlines. They screened Little Man!

OSDI 2006 - Day 3 and HotDep 2006

Category: By AG
Day 3 of OSDI was mostly "all distributed." Ended at around noon, and then continued as HotDep. It had some interesting papers and did put forth many interesting ideas. Chunkfs paper was presented by Val, and was well received. The intention of HotDep was to get the ideas out for discussion and was achieved pretty satisfactorily.

During long lunch, lasting ore than 90 minutes, I managed to wander around the Seattle downtown. The downtown full of steep roads, is nothing but ridiculously expensive. But even though for one shop I had to go beyond window shopping to realize that its sometimes good to skip lunch. It was a grand piano shop.
One (master) piece that I was looking at was made early in the century and was brought from New York. The shop attendant, with the coat and bow attire just like the pianist ready to play in an concert, explained the history of that piano in brief. He, himself, was a great pianist. His fingures just danced on the keys creating pleasant sound echoing throughout the grand shop. I didn't tried to play it myself, respecting the age-old piano and the attendant's piano skills (and his ears too ;)). It was for some $ 84K odd.

OSDI was fun! Operating systems researh is hot as always, and Linux rocks! Its baby of every OS researcher now, its everyone's tools, everyone's testbed. Plenty to takeaway from OSDI and HotDep! Thanks to USENIX.

OSDI 2006 - Day 1 & Day 2

Category: By AG
Seattle is not so different than Boston, both are a typical American metros, both have some waterbody and both are big. Execpt that it rains a lot in Seattle and there are noticeably many homeless in Seattle. Public transport has good connectivity, but its necessary to make sure you have change before boarding a bus. Starbucks is at every nook and corner of the city, unsurpringly enough, since it was founded here.

Here for a conference and Workshop, OSDI and HotDep, by the courtesy of USENIX Travel Grant. The conference is amazing so far. The attendee list is almost who's who of the OS research including Andrew Tannenbaum and many professors and industry people whose homepage I've visited at some point. Its good to have all such people under one roof brainstorming. Undoutably, its motivating to talk and meet with such people and get inputs on the current hot topics in OS and about the filesystems topics that I'm exploring. It feels good when people already knows about your thesis research even before you tell them about it :) But at the same time it makes you feel all the more responsible for putting extra efforts in your work.

Being a premier OS conference, talks at OSDI are always interesting, and this year was no exception. Most noticeable was "Rethink the Sync," which talked about achieving performance closer to asynchronous I/O but with synchronous guarantees. Among others was one describing virtual memory model for garbage collected applications called CRAMM and OS profiling and state monitoring tool called "Flight Data Recorder."

On day 2, most influential talk was about how Google manages its data storage by a storage system called Bigtable. It gave a birds eye view of the work, but was good enough to let the audience know what it is. There were huge questions everyone had about this...and unsurprisingly the first one to question was a guy from Yahoo :)

With a quick lunch I managed to take some time off to wander around the Seattle downtown. Of course after taking care of the homework that I had to turn in today ;) Conference hotel being at the heart of downtown, every area of the downtown was reachable and I could lay my hands on some stuff for the home coming 2006. Its called the "Public Market Center" and is no different than the camp's fashion street of Pune minus the chaos. Most shops also were speciality stores, like having antiques or some having arabic goods, all wooden decoratives or some even having just black magic stuff!

Evening was spent at the Museum of Flight, which is a Paul Allen's own toy room, so the evening was sponsored by Microsoft and turned out that the USENIX luncheon was better than the dinner :| Along being a museum of flight, it also hosts Leonardo da Vinci's museum. It had nice little models that leonardo had thought about during his 67 years of life, making him greatest of inventor ever! His 13,000 pages of written work is incomparable to the all OSDI-like conference proceedings combined ;)

Sleep calling..

Surya Nagri (a.k.a. Sunnyvale, CA)

The bay area climate is unbeatable..is just too good. Was there for a quick 3 day visit. Actually the city isn't different than any other Indian metro, except that it had many non-Indians too ;) Every taxi I took was driven by an Indian. Surprisingly enough, the driving license test in that area is also available in Punjabi! Being like any other Indian metro, plently of Indian restaurants..the one at which we stopped was relatively vacous, but we had to appreciate the hospitality of the restaurant owner...he got us chicken biryani without us even ordering it (lol!!)...and it tasted good too, so we appreciated it even more.

Last week made me took an exam which was nothing far from awful. Also I got to hear Vinton Cerf, one of the fathers of the Internet, who was here as a guest speaker at the Provost Lecture Series. He empahasized topics such as role of QoS and internet enabled devices in the future of our connected chaos. He also talked about the Inter-Planetary Networks that he is working on currently with NASA. But to my surprise, he didn't touch upon the role of Social Networks in the coming years. This was followed by my own talk in one of the undergraduate Operating Systems class. Was on file systems and things that I am working on recently.

Chunkfs, a recovery-driven file system design approach

Category: By AG
Its blossoming and slowly starting to take shape as a form of numerous hacks in the actual ext2 driver code, but still a looong way to go.

Chunkfs is an application of file system design approach for easy and fast recovery of file system after system crash and is going to be my thesis topic. A preliminary paper, entitled "Chunkfs: Using Divide-and-Conquer to Improve File System Reliability and Repair", accepted at Usenix HotDep 2006 can be found here (once its ready to go public).

Git repository for the prototype implementation in FUSE (File System in Userspace) is at: git://cislinux.cis.ksu.edu/fuse-chunkfs. It requires libext2 and libfuse.

The tools for the same (fsck and mkfs - both unstable) can be found at: git://cislinux.cis.ksu.edu/chunkfs-tools

Gandhigiri..and chords

By AG
After a strong recommendations from near and dear ones both far and near, I had to watch this movie..Lage Raho Munna Bhai. Especially when its going for Oscar Nomination.

Its crisp and has a terrific plot. Not that the ideology is new, but its application is contemporary. A good watch :) And its even better after a belly full of Malai Kofta, Aalo Vada, Kadhi and Veg-Pulav :D prepared for the potluck in the apartment after which the movie followed.

My goal is to learn piano chords and its amusing me ever since I bought this casio from a garage sale...much time spend on it as well over the weekend.
