i guess this is the first time something happened in this class actually made me happy. more on the copying incident from last entry.

email from professor:
Hi,
The TA acknowledged that she did indeed use your solution for those to be posted. This should not have happened without your permission, and you should receive (perhaps already have) a personal apology from her. Also, you deserve credit for the work, and I would be glad to credit your name on the solution sheet -- is this OK with you? Or if you prefer, you can remain anonymous, or we can post alternative solutions -- your choice.

I'm sorry this happened this way, but at least I hope you feel proud that your solutions were judged to be a model to show the rest of the class -- that's very good work.

email from TA

Hi,
This is Xin Lu, TA for the 22c:054 class.
I'm sorry I didn't ask for your permission before putting your solution to the web. If you feel uncomfortable with that, I could take it off. Otherwise, would you like your name be put after that on the web?
