Here are two interesting pieces: both are from Mendelssohn’s A Midsummer Night’s Dream—overture or the incidental music suit, arranged for solo/duet piano. 1. Martha Argerich and Cristina Marton play Ouverture and Scherzo Summernight Dream: 2. the famous Scherzo, paraphrased by Rachmaninov ester egg: the flute solo of the Scherzo is a very difficult solo
This is from the Game Changer podcast:Behind the Stars: Uncovering the Biases in Online Reviews | with Tommaso Bondi. Link to the podcast website. The podcast features Tommaso Bondi (link to his webpage) and his paper Alone, Together: A Model of Social (Mis)Learning from Consumer Reviews. The problem roots in cultural markets, like movies, music, books where consumers discover and experience the product without knowing their exact utilities ex-ante. To decide which product to consume, we might utilitze reviews to gauge the unknown utility....
Three miscellaneous for the weekend: the procrastinator Did you know Felix Mendelssohn composed music for Shakespeare’s comedy, A Midsummer Night’s Dream, not once, but twice? At the tender age of 17, he crafted the overture (Op. 21, 1826). Later in his career, in 1842—just five years before his demise—he completed a full suite of incidental music (Op. 61) for the play’s production. Btw, the beloved Wedding March we all know is from this very suite!...

ChatGPT makes it much easier to modify configurations for my website. I changed the font to Montserrat—an open source font provided by Google font (fonts.google.com) that is highly similar to Google’s proprietary logo font Product Sans. Well cause: Google Sans [and Product Sans] is not available for use outside of Google. It is our brand font and is exclusively used in Google products. Fine. Fonts provided and maintained by Google font has a delivery service—everytime the website loads, it fetches font files from Google....
Something interesting happened in today’s seminar course. One of my classmates presented his final paper, and as expected in a seminar setting, our instructor, Hu Fu, wants everyone to stay engaged and understand what’s being discussed. Today’s presenter had clearly prepared and read the paper but had no clue how to structure an academic talk. He skipped all the basics—no background, no context of the model provided—and jumped straight into the technical details....
Motivation Preview from problem set 2, question 4: (link to original file) This gives a reduction: [submodular welfare maximization] <= [maximize a monotone submodular function s.t. matroid constarint]. Remarks: hardness & approximation of the problem [submodular welfare maximization] >= [maximize a monotone submodular function s.t. matroid constarint] (Is it true though?). maximize monotone submodular function is hard. Because, for instance, one can reduce Partition problem to it. That’s why we started looking at submodular maximization s....
Following the news of Amazon’s lawsuits and after skimming through the complaints, here are my thoughts. price do go up | 羊毛出在羊身上 There’s no free lunch. While prices may seem lower on Amazon, the market is interconnected. Amazon’s attempt of achieving lower price would backfire. Amazon’s power forces sellers to comply with its Buy Box rules, meaning they must keep prices equal or higher across all channels to access Amazon’s vast demand....
Following yesterday’s coverage on Amazon’s series of trouble with antitrust regulators, I digged into the filing complaint of CA v Amazon and the orginal complaint and amended complaint of FTC v Amazon. We can obtain quite a bit of interesting information about Amazon’s Buy Box: (at least, from the perspective of regulators…) first, Amazon chose to make purchasing outside the Buy Box hard: Nearly 98% of Amazon sales are made through the Buy Box....
Here are recent news about Amazon Buy Box’s into antitrust trouble: California sues Amazon | September, 2022 Timeline: Sept. 2022: Attorney General Bonta sued Amazon in the Superior Court of California. The lawsuit basically focused on accusing Amazon penalizing sellers for listing products at the lower price on other selling channels—that if Amazon spots a product listed elsewhere cheaper, it will often remove the seller from the Buy Box on Amazon....
