In some sense, we were office mates. I was sharing a big office in the fifth floor of the math and computer building, and Sheng's office was slightly tucked inside that office. We both were among the few who used to work late in the night. We used to go for coffee/tea in the night to the campus center, and that's when we started playing table tennis there. It was usually less crowded at those times. I had never touched a table tennis racket before I met him, but recently I have won some small local tournaments here, and all the credit go to Sheng for his coaching -- by just playing with me patiently for several days and months.<br /><br />He used to be passionate about music and photography. He had a sophisticated Nikon camera at that time, and I have pictures of us surrounded by snow during the Waterloo winter days. <br /><br />I helped him move his stuff to Kent, and I had kept in touch even after I moved back to India. During my several visits to Waterloo afterwords, I have never missed to meet him. Either he would come down to Waterloo to meet me or I would visit him in London. We have discussed quite a bit about cultural revolution in China and Indian democracy.<br /><br />His generosity and gentleness have been mentioned here, and I echo the sentiments. I will miss him during my visits to Waterloo.<br />-- Venkatesh RamanAnonymousnoreply@blogger.comtag:blogger.com,1999:blog-20067416.post-83255767409917731232012-02-06T16:44:26.296-05:002012-02-06T16:44:26.296-05:00I will miss Sheng.

Over that time, he was my professor for two courses.<br /><br />I have fond memories of sitting in Sheng's office, admiring his books and his piles of papers, and talking about his past students and what they were up to.<br /><br />Sheng was very generous with me. I remember popping into his office at the end of my second or third year of university and nervously asking him if he wanted an undergraduate research assistant. I had no idea what to expect. By that time, it was too late to apply for any grants, but Sheng decided that he would employ me on a part time basis out of pocket! That was a fun summer, an interesting project, and where our friendship began.<br /><br />The next summer, we got a small NSERC award and worked on maintaining Grail+. Again, Sheng was very generous and always supportive.<br /><br />In my final year, Sheng supervised my thesis project and together we re-implemented Grail+.<br /><br />I will always remember him.

I enjoyed debating with him and picking his brain. It was very interesting and enlightening to see someone who spent most of his academic career dealing with automata and theoretical comp sci. transfer these skills to the social sciences world. We even had a long term plan about writing a paper together surveying authoritarian regimes and examining their successes in certain aspects where we thought democratic regimes had failed. He wasn't an advocate of authoritarianism of course but that's how someone who's versed in logic thinks. He's interested in mining the good things out of the bad no matter how. We also played ping pong together and he taught me how to return the insane topspin that he used to throw at me. It's very sad. I used to look forward to visiting him in his book-filled brightly-lit office. He will certainly be missed. My thoughts and condolences go out to his family and friends.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-20067416.post-46310991502887018072012-01-26T00:17:54.365-05:002012-01-26T00:17:54.365-05:00I was so shocked on the news that Dr. Yu passed on...I was so shocked on the news that Dr. Yu passed on the Chinese New Year's eve.<br /><br />I was a PhD student at UWO and took one course on Object Oriented Languages offered by him.

I work in late night like him, so we meet in the corridor many times at night time when the UWO looks silent and have chat about many things, even last week or two I have chat with him regarding our future plan etc. I think I last hear his footsteps in our corridor just several nights back it was around midnight and thought to open the door and a have chat but was little bit lazy and thought maybe next time, who guess that would be the last chance.RIP for Sheng.Mahdihttps://www.blogger.com/profile/11728985703673251906noreply@blogger.comtag:blogger.com,1999:blog-20067416.post-57607646752689035202012-01-25T15:09:45.958-05:002012-01-25T15:09:45.958-05:00Thanks Jeff for the nice comments about Sheng.
