Sometimes at very critical times. But can you make it the 'default' excuse even in cases where the process is supposed to be under a lot of human supervision? <br /><br />I experienced a small incident where people seem to depend on software too much that when something goes wrong, they blame it on the the software entirely. Although, clearly it was their mistake in the first place and they were supposed to verify the outcome of the software anyways.<br /><br />So here's the story... I am planning to attend a conference in Spain in April, and since Sri Lankans need visas to enter almost any country in the world, I had to apply for a Schengen Visa at the Spanish Consulate in Boston. They took 2 weeks to process the visa application, and when I got my passport back, I noticed that they have issued the visa from 18-04-00 to 10-05-09. This is absurd because I only asked the visa for 7 days and they had given it for more than 9 years! Had they given the visa for 9 years forward from now, I would've been extremely happy as I could have avoided any future paperwork messes and the ridiculous amounts of money they require to process the applications. But clearly, this was a mistake. So I reported it to avoid any confusion (and with the recent luck I have been having with travel visas, it was definitely better to be safe than sorry!).<br /><br />Their explanation was very simple: it was a mistake in their software. Now, tell me, do they have some very complicated OCR software to automatically figure out the date I want to go to Spain by processing all the paperwork I submitted? Even if that was the case, shouldn't they at least check the dates of the visa manually before issuing it? If a software was doing all the processing, why did it take them 2 weeks to process the application? My guess is that, it was a small typo and they failed to spot it. One thing that surprises me most is the lack of a software based control to ensure the 'visa issued date' to be less than the 'visa valid from date'. Anyway, after my complaint, I got the visa for the correct time period. But it made me wonder about the correctness of the software that are used by Government agencies. If they can't do a simple date check like this, I fear what other pieces of controls these software might be missing! Even more worryingly, it is sad to imagine they might be using the data collected through such buggy systems for making decisions that might affect somebody's entire future!Unknownnoreply@blogger.com3tag:blogger.com,1999:blog-1193765205352943652.post-40183180430726675202009-01-27T12:35:00.000-08:002009-01-27T13:42:14.818-08:00Buddha LoungeThis is the name of a bar/night club I see on a day-to-day basis these days (because it's very close to where I am staying right now). Every time I see it, I keep on thinking why the club owners thought having the name 'Buddha' would be a nice fit for the club. Does it sound trendy to have a religious icon from the east?

The workshop was really interesting, and it made me wonder whether people really need to adopt digital identities to protect themselves online. <br /><br />The work at the <a href="http://dig.csail.mit.edu/">research group I am affiliated with</a> at MIT, revolves around having transparent and accountable data on the web. This "data", I believe, includes the "online identities" of people as well. So, I am trained to think that you should be held accountable for whatever you say on the web! However, if the things you say are highly controversial, even unlawful in certain jurisdictions, and can have an adverse effect on your career, it seems reasonable to go under a pseudonym and write whatever you have to say, abdicating all the responsibilities and even the subsequent credit to yourself as a person in the real world. <br /><br />Another point that was brought up in the discussion was that whether going under a pseudonym is at all better than writing something anonymously. To me, it doesn't appear to have much of a difference though. However, unlike an anonymous author, an author operating under a pseudonym will have a social circle who would promote the writings to a greater community under their own guises. There were so many interesting stories that came up in the discussion out of their own experiences!<br />If you are interested in these case stories and the "patterns" that emerged, have a look <a href="http://patternlanguagenetwork.myxwiki.org/xwiki/bin/view/Groups.DigitalIdentities/outputs">here</a>.<br /><br />Anyways, I still think that if you want to write about something you should fully disclose who you are. Coming from an open culture, where full disclosure means more visibility and hence more recognition to you and your work, it seemed a bit bizarre that you'd want to hide away under some name if you really want to say something on the web. <br /><br />I wonder if someone would ever come up with a technical or a legal solution to this problem? If you have any thoughts on this issue, please do comment!Unknownnoreply@blogger.com3tag:blogger.com,1999:blog-1193765205352943652.post-43375594184970834592009-01-05T09:52:00.000-08:002009-01-05T10:09:41.111-08:00I am back!I have been away from blogging for way too long! For some time, I was using this blog only to experiment my summer '08 project at the University of Southampton, UK on "Detecting Creative Commons License Violations on Flickr Images on the web". In fact, if you visited this blog between now and last summer you might have seen weird images embedded in the blog, and might have wondered what the heck I was doing :)<br /><br />Anyways, I made a new year resolution to blog more often. I've always experienced that thinking aloud is extremely beneficial in several ways. Imparting knowledge (or maybe sometimes nonsense) to others is really good, and in my case it really helps to structure my ideas much clearly. Since I really need to be in the writing mood soon (SM thesis due by the end of the Spring semester :( ), I believe this would give me good practice!<br /><br />So stay tuned :)Unknownnoreply@blogger.com4tag:blogger.com,1999:blog-1193765205352943652.post-42213633097805962672008-08-07T14:03:00.000-07:002008-08-07T15:48:37.500-07:00Summer Doctoral ProgramThis post is long overdue. But it is better late than never, right? :)<div><br /></div><div>So the Summer Doctoral Program or the "SDP" as we called it, is finally over. It was two weeks of intense seminars and discussions all in an attempt to shape and define what Web Science is. Key themes were how to ensure privacy, information accountability and transparency, how to research and predict web based social behavior on a large scale, several intros to the Semantic Web and very interesting student presentations on our own Ph.D topics ranging from porn to e-governments! </div><div><br /></div><div>If you are interested in finding out what kind of things were discussed, have a look at the <a href="http://students.oii.ox.ac.uk/sdp:sdp2008">wiki</a>. I have also summed up my thoughts on Web Science in this <a href="http://students.oii.ox.ac.uk/sdp:sdp2008:workspace:oshani_seneviratne:web_science">essay</a> in case you are interested.</div><div><br /></div><div>The SDP participants were from very diverse fields, and it was really interesting to interact and learn from each other. I think we all made some very good friends at the SDP. </div><div>There was also an IRC back channel, and I simply loved the discussions happening there. It was the place to ask stupid questions and even throw witty remarks at others!</div><div><br /></div><div>We also managed to design a T-shirt for the SDP. Many kudos to <a href="http://www.commphd.com/Site/Welcome.html">Matthew Weber</a> for the design. <a href="http://www.ibiblio.org/hhalpin/">Harry Halpin</a> and I made sure that the RDF syntax in N3 is well-formed. After all, I don't think I would be able to wear a T-shirt with invalid syntax, especially when TimBL is around, now would I? :)</div><div>There is a <a href="http://www.cafepress.com/OIISDP2008"> Café Press shop </a>where you can purchase a t-shirt, a long-sleeve t-shirt or a mug if you like!<br /></div><div><br /></div><div>The front design looks like this:</div><div><br /><a onblur="try {parent.deselectBloggerImageGracefully();} catch(e) {}" href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjA4w1zzXbCcOgxIOD6ThS59Z6zQWZl1LWtsdV7NYSREDC_dSjFxA0SXlU7yN_CdBrpTE8LpYrkyzzFUYWhxBj85QNUFNAI1KGLL6XCZPYpn1jz_kelxgcTZUyHvxmW6J6qLiWDt-fp3AA/s1600-h/TShirtFront2-3.jpg"><img style="display:block; margin:0px auto 10px; text-align:center;cursor:pointer; cursor:hand;" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjA4w1zzXbCcOgxIOD6ThS59Z6zQWZl1LWtsdV7NYSREDC_dSjFxA0SXlU7yN_CdBrpTE8LpYrkyzzFUYWhxBj85QNUFNAI1KGLL6XCZPYpn1jz_kelxgcTZUyHvxmW6J6qLiWDt-fp3AA/s200/TShirtFront2-3.jpg" border="0" alt="" id="BLOGGER_PHOTO_ID_5231901287778904034" /></a>What's the deal with the dingo you ask?

First there was a host of vampire invitations that really irritated me, then there were zombies, hugs, roses, angels, you name it.<br /><br />Very recently one of my closest friends sent me an invitation to this "When will you get married" application. Here is a screenshot of that:<br /><br /><a onblur="try {parent.deselectBloggerImageGracefully();} catch(e) {}" href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjHDYbiKzCv1oj9NShP7YMiUzLNtoEryWX5PZL6WE3eZ8WYKEGHHHfdlR_jPSDrpkZE7G1ALDHsaH2CsAnariw4Wuegrtb9u33blcvEAcG95OonNYT64aU2s2sFtHpLABbCX4raum2LcwI/s1600-h/marry.png"><img style="margin: 0px auto 10px; display: block; text-align: center; cursor: pointer;" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjHDYbiKzCv1oj9NShP7YMiUzLNtoEryWX5PZL6WE3eZ8WYKEGHHHfdlR_jPSDrpkZE7G1ALDHsaH2CsAnariw4Wuegrtb9u33blcvEAcG95OonNYT64aU2s2sFtHpLABbCX4raum2LcwI/s200/marry.png" alt="" id="BLOGGER_PHOTO_ID_5185454676928168498" border="0" /></a><br />Notice that it says "Patented Wedding Algorithm A.I" :).<br />Anybody with even a teeny bit of common sense should be able to see that this is an attempt to get your personal information, and popularize this application by asking you to send this out to at least X number of your friends . But still, people try this out<br />!

Actually to let you know a little secret I am even very clumsy with the chopsticks! However, last Friday I was part of a team which made sushi for 80 people (this was for CSAIL GSL). Isn't that cool or what?? :)<br /></div><div style="text-align: justify;"><br /></div><div style="text-align: justify;">The team was <a href="http://people.csail.mit.edu/bohsu/">Paul</a>, Jen, <a href="http://yeoyeo02.googlepages.com/">Thomas</a> and <a href="http://people.csail.mit.edu/yklee/">Yoong-Keok</a>. Paul was the master chef, and out of all 5, I guess I was the one who was most alien to the sushi preparation :). However, I now know how to do it, and I'd soon try it on my own. And I think I'd even become a huge sushi fan!!<br /></div><div style="text-align: justify;"><br /></div><div style="text-align: justify;">Sushi preparation is not that hard. However, it is bit time consuming and requires a bit of patience. We spent about 8 hours on Thursday evening cooking rice and wrapping up the sushi.

I went on this trip with two Sri Lankan friends I met here - Varuni and Radheeka, studying at Boston University and University of Southern California respectively. We went to New York, New Jersey, Washington DC and Virginia. We visited so many famous places, museums and even got to see two Broadway shows including <a href="http://www.newyorkcitytheatre.com/theaters/minskofftheater/theater.html">Lion King</a> and the <a href="http://www.blueman.com/">Blue Man Group</a>.<br /><br />The trip was lot of fun and I had loads of experience (both good and bad). The good stuff were the amazing sights and sounds we got to experience (including the 100th anniversary of the crystal ball dropping at Times Square, getting <span style="font-weight: bold;">FRONT ROW</span> seats at the Blue Man Show, etc), having got to stay in 'real' houses which I so dearly missed, and getting to taste Sri Lankan food. Bad experiences were delayed flights and lost baggages ruining some outing plans, getting sick, and sometimes feeling that luck was never on our side when it comes to the weather and timing :(.<br /><br />However, we had an awesome time, and we are determined to go on similar kind of trips in the future covering all 50 states of the United States!<br /><br />Here are some of the pictures we took on this trip:<br /><br /><a href="http://www.flickr.com/photos/oshanis/sets/72157603681600152/show/">http://www.flickr.com/photos/oshanis/sets/72157603681600152/show/<br /></a><br />And here are some of the sights and sounds we got to experience.<br />(Fair warning though.. these are amateur videos, so you might get giddy after watching those for few seconds :)<br /><br />Lights near the Rockefeller Center:<br /><br /><object height="355" width="425"><param name="movie" value="http://www.youtube.com/v/6QlVbwAtomw&rel=1"><param name="wmode" value="transparent"><embed src="http://www.youtube.com/v/6QlVbwAtomw&rel=1" type="application/x-shockwave-flash" wmode="transparent" height="355" width="425"></embed></object><br /><br />Ice Skating:<br />(tried and failed twice, and now scared to death to try again :)<br /><br /><object height="355" width="425"><param name="movie" value="http://www.youtube.com/v/Y6e_y3UXHeM&rel=1"><param name="wmode" value="transparent"><embed src="http://www.youtube.com/v/Y6e_y3UXHeM&rel=1" type="application/x-shockwave-flash" wmode="transparent" height="355" width="425"></embed></object><br /><br />New Year's eve at Times Square:<br /><br /><object height="355" width="425"><param name="movie" value="http://www.youtube.com/v/w9X4uYSb8vs&rel=1"><param name="wmode" value="transparent"><embed src="http://www.youtube.com/v/w9X4uYSb8vs&rel=1" type="application/x-shockwave-flash" wmode="transparent" height="355" width="425"></embed></object></div>Unknownnoreply@blogger.com0tag:blogger.com,1999:blog-1193765205352943652.post-91049016191408378532007-12-13T17:36:00.000-08:002007-12-13T18:19:19.527-08:00R-Store<div style="text-align: justify;"><a href="http://code.google.com/p/r-store/">R-Store</a> is a Java library which converts RDF data into a relational database schema.

Well, I have the DB finals on Tuesday, the final project to demo next week, and the research supervision form to hand over. So, in the midst of all this chaos, I thought I should take a small break and do something different (at least to make sure I would not go insane :). I wish I had some photos to upload from the visit, but the museum folks said that I cannot take any photos inside... too bad. The cooooold weather outside made me lazy to take the camera out and shoot.<br /><br />So, being the classical music nut I am, I really enjoyed this outing. Oh BTW, this was organized by the Sid-Pac outing committee, and I got to meet some really cool people as well.<br /><br />Hoping to participate in more outings like this in the future!!<br /></div>Unknownnoreply@blogger.com0tag:blogger.com,1999:blog-1193765205352943652.post-16694939061938985612007-11-30T05:54:00.000-08:002007-11-30T06:12:23.962-08:00New Addition to TabulatorFor those of you don't know <a href="http://www.w3.org/2005/ajar/tab">Tabulator</a> is a RDF data browser originally hacked up by TimBL, and developed over the years by summer interns at DIG.<br /><div style="text-align: justify;"><br />For the past few weeks, I've been trying to understand and write code for the Tabulator. My task was to provide a justification trace for the annotated transaction log given out by the AIR reasoner. Here's a screen shot of how it looks like now:<a onblur="try {parent.deselectBloggerImageGracefully();} catch(e) {}" href="http://people.csail.mit.edu/oshani/tami_justification_trace.png"><img style="margin: 0px auto 10px; display: block; text-align: center; cursor: pointer; width: 321px; height: 200px;" src="http://people.csail.mit.edu/oshani/tami_justification_trace.png" alt="" border="0" /></a><br />If you want to try this out, install the <a href="http://people.csail.mit.edu/oshani/tab.xpi">Firefox Extenstion with this latest change</a>, restart Firefox, and navigate to <a href="http://swiss.csail.mit.edu/projects/tami/output1.n3">this file</a>.<br /><br />Overall, my experience with the Tabulator code amazes me as to what javascript is capable of. But however, I've had my share of nightmares debugging the code! Sometimes it was pretty painful, but nevertheless I learnt so many lessons :)<br /><br />By the way, the Tabulator project is open source, so if you'd like to contribute you are more than welcome to do so.<br /></div>Unknownnoreply@blogger.com0tag:blogger.com,1999:blog-1193765205352943652.post-4186047088446586272007-11-17T15:00:00.000-08:002007-11-17T15:15:02.903-08:00SavantsI've always wanted to do number manipulations in my head. I am no savant, so the best I was able to get to was powering up any 2-digit numbers within my head in less than 20 seconds. It's a very simple trick where you multiply the nearest whole number with the equi-distant number from the number you are actually squaring and adding the power of the distance. For example, if you want 99^2, you do (99+1)*(99-1) + 1^2.<br /><br />I came across this on Google Video and I find this man to be simply amazing...<br /><br /><embed style="width:400px; height:326px;" id="VideoPlayback" type="application/x-shockwave-flash" src="http://video.google.com/googleplayer.swf?docId=4913196365903075662&hl=en" flashvars=""> </embed>Unknownnoreply@blogger.com0tag:blogger.com,1999:blog-1193765205352943652.post-61419327412536674862007-11-17T13:15:00.000-08:002007-11-17T13:17:27.153-08:00Home PageI finally created my <a href="http://people.csail.mit.edu/oshani/">home page</a>!<br /><br />I've been putting this off for weeks, and I am glad that it is over.

Since I would get awfully bored with 3 days on a row at my apartment alone, I called up Varuni and we planned a day out exploring Cambridge (mostly around MIT).<br /><br />We first went to the <a href="http://web.mit.edu/museum/">MIT Museum</a> which is very close to where I live (shame on me for not visiting it before!). I was very eager to see the hologram gallery. I was really fascinated to see what laser and few pieces of glass could do! For example, you can see the following "portrait" in 3D!<br /><br /><a onblur="try {parent.deselectBloggerImageGracefully();} catch(e) {}" href="http://people.csail.mit.edu/oshani/photos/nov_2007/MITMuseum/hologram.JPG"><img style="margin: 0px auto 10px; display: block; text-align: center; cursor: pointer; width: 126px; height: 166px;" src="http://people.csail.mit.edu/oshani/photos/nov_2007/MITMuseum/hologram.JPG" alt="" border="0" /></a><br />For some odd reason Varuni was very much intrigued with this "oil bathing machine". I found it quite gross actually :) Anyway, it was very nice to see very cool mechanical things which were just built for fun.<br /><br /><a onblur="try {parent.deselectBloggerImageGracefully();} catch(e) {}" href="http://people.csail.mit.edu/oshani/photos/nov_2007/MITMuseum/oil_machine.jpg"><img style="margin: 0px auto 10px; display: block; text-align: center; cursor: pointer; width: 136px; height: 183px;" src="http://people.csail.mit.edu/oshani/photos/nov_2007/MITMuseum/oil_machine.jpg" alt="" border="0" /></a><br />My favorite section was of course the robots! Sometime back I watched a program on Discovery about <a href="http://web.mit.edu/newsoffice/2001/kismet.html">Kismet</a> - a sociable robot developed at the MIT AI lab. And yesterday, I was looking face to face with this Kismet!<br /><br /><a onblur="try {parent.deselectBloggerImageGracefully();} catch(e) {}" href="http://people.csail.mit.edu/oshani/photos/nov_2007/MITMuseum/akismet.jpg"><img style="margin: 0px auto 10px; display: block; text-align: center; cursor: pointer; width: 145px; height: 195px;" src="http://people.csail.mit.edu/oshani/photos/nov_2007/MITMuseum/akismet.jpg" alt="" border="0" /></a><br />We then explored some parts of MIT. I was of course playing the role of the tour guide - showing what little parts of MIT I knew to Varuni. Here's both of us standing on the lawn in front of the Oval auditorium right next to the Student Center.<br /><br /><a onblur="try {parent.deselectBloggerImageGracefully();} catch(e) {}" href="http://people.csail.mit.edu/oshani/photos/nov_2007/MIT/infront_of_oval.jpg"><img style="margin: 0px auto 10px; display: block; text-align: center; cursor: pointer; width: 200px;" src="http://people.csail.mit.edu/oshani/photos/nov_2007/MIT/infront_of_oval.jpg" alt="" border="0" /></a><br />Then it was the Charles River... the view was so breath taking. May be it was the lighting condition and the time of the day or even the weather. I don't know what, but somehow, it was so nice. <br /><br />This is a picture of both of us in front of the river.<br /><br /><a onblur="try {parent.deselectBloggerImageGracefully();} catch(e) {}" href="http://people.csail.mit.edu/oshani/photos/nov_2007/CharlesRiver/charles_river_3.jpg"><img style="margin: 0px auto 10px; display: block; text-align: center; cursor: pointer; width: 200px;" src="http://people.csail.mit.edu/oshani/photos/nov_2007/CharlesRiver/charles_river_3.jpg" alt="" border="0" /></a><br />Of course you can see the Boston skyline behind. Here's the other part of the skyline .<br /><br /><a onblur="try {parent.deselectBloggerImageGracefully();} catch(e) {}" href="http://people.csail.mit.edu/oshani/photos/nov_2007/CharlesRiver/Boston_skyline_1.jpg"><img style="margin: 0px auto 10px; display: block; text-align: center; cursor: pointer; width: 200px;" src="http://people.csail.mit.edu/oshani/photos/nov_2007/CharlesRiver/Boston_skyline_1.jpg" alt="" border="0" /></a><br />We also went down to the MIT boat dock yard, and said hello to these cute friends!<br /><br /><a onblur="try {parent.deselectBloggerImageGracefully();} catch(e) {}" href="http://people.csail.mit.edu/oshani/photos/nov_2007/CharlesRiver/ducks.jpg"><img style="margin: 0px auto 10px; display: block; text-align: center; cursor: pointer; width: 169px; height: 127px;" src="http://people.csail.mit.edu/oshani/photos/nov_2007/CharlesRiver/ducks.jpg" alt="" border="0" /></a><br /><br />All in all, it was a very nice day indeed!Unknownnoreply@blogger.com1tag:blogger.com,1999:blog-1193765205352943652.post-45189727504427161232007-11-05T07:22:00.000-08:002007-11-05T07:41:47.018-08:00Daylight saving timeThis is not any major news.<br /><br />But the interesting thing is now I am 16 hours behind my brother who lives in Melbourne, Australia!<br /><br />It used to be 14 hours, but on last Sunday my time here was pushed back by one hour to mark the END of daylight saving, and his time was pushed forward by one hour to mark the START of daylight saving time!<br /><br />We had to coordinate different calling times, cos either one of us would be either at work/uni or too sleepy to talk :)Unknownnoreply@blogger.com0tag:blogger.com,1999:blog-1193765205352943652.post-26477733491440867212007-10-31T17:24:00.000-07:002007-10-31T17:39:08.194-07:00Halloween!Today was one of these days I really wish I had my camera with me :) It is Halloween here and students here at MIT celebrate it in a grand style.<br /><br />I was waiting outside one of the classes to end (because my class was right after it), and I could not help but laugh seeing all the students who came out of the class dressed up in very weird costumes - the first guy was dressed up as a banana, and another girl was dressed up as a sumo wrestler (she was wearing a balloon like thing which took up the entire corridor width), there were few witches, and one guy was even wearing a bathrobe!<br /><br />It is not only students who seemed to be enjoying Halloween. I even came across few professors who were in costumes - most of them seemed to have take up characters from Harry Potter.<br /><br />It seemed really fun to be dressed up like that. I was wondering what would happen if we start a similar tradition in Sri Lanka ;)Unknownnoreply@blogger.com0tag:blogger.com,1999:blog-1193765205352943652.post-55279015653861494012007-10-27T16:00:00.000-07:002007-10-27T17:18:48.721-07:00Kathina<div style="text-align: justify;"><a href="http://www.cag.csail.mit.edu/%7Esaman/">Prof. Saman Amarasinghe</a> and his wife Praneeta Amarasinghe was very kind enough to take me to the <a href="http://www.nebvmc.org/">New England Buddhisht Vihara and Meditation Center</a> in Framingham, MA for the annual Kathina (Robe Offering) ceremony today. And it was a really good experience for me!<br /><br />Kathina is a traditional buddhist ceremony which marks the ending of the three-month rainy season (Vassana) retreat that usually begins on the Esala full moon (Poya) day. This is supposed to be an important event in Theravada Buddhist tradition and is considered as a period of reflection, meditation and concentration on Buddhist teachings.<br /><br />The ceremony started with "dana" (serving food to the monks). This was exactly like how we do in Sri Lanka! Here is a picture I took of the monks just before they were offered the ''dana".<br /><br /><a onblur="try {parent.deselectBloggerImageGracefully();} catch(e) {}" href="http://people.csail.mit.edu/oshani/photos/oct_2007/DSC09616.JPG"><img style="margin: 0px auto 10px; display: block; text-align: center; cursor: pointer; width: 200px;" src="http://people.csail.mit.edu/oshani/photos/oct_2007/DSC09616.JPG" alt="" border="0" /></a><br />Since coming to the US this was the first time I met so many Sri Lankans!

Although I did not know her beforehand, she and I share many things: our <a href="http://www.visakhav.org/">alma mater</a>, the fact that we both *just* finished our undergrad before coming here, and even our birthdays! We also have quite a large number of mutual friends. So whaddoyaknow... we almost instantly become very good friends - gee... I wish I knew she was here earlier.<br /><br />Overall, it was a really good day for me!

If you have no idea what gsl is - well, it is a social event for MIT CSAIL grad students where they have to sign up to cook lunch once for the year, and get free lunch which is cooked by other students once a week on every Fridays.<br /><br />The most interesting thing about gsl is the diversity of food. Every week, there is some new food to try out. Today it was falafel and hummus, last week it was fajitas, salsa, and guacamole, the week before it was vegetable radiatore and potato gnocchi, etc and etc. When I see the email announcing the food, I always have no ideas how it will look like or what it will taste like. But so far it has been great! I mean the food is not the best culinary efforts I've seen (after all, these food are prepared by MIT students :), but still it is great to taste all these different kinds of food from all around the world!Unknownnoreply@blogger.com0
