Accepted to The Web Conference 2025, Sydney Australia💖💖💖 Ophir Friedler, Hu Fu, Anna Karlin, Ariana Tang abstract Platforms design the form of presentation by which sellers are shown to the buyers. This design not only shapes the buyers’ experience but also leads to different market equilibria or dynamics. One component in this design is through the platform’s mediation of the search frictions experienced by the buyers for different sellers. We take a model of monopolistic competition and show that, on one hand, when all sellers have the same inspection costs, the market sees no stable price since the sellers always have incentives to undercut each other, and, on the other hand, the platform may stabilize the price by giving prominence to one seller chosen by a carefully designed mechanism....

I spent two days going nuts over a Python script not recognizing directories properly when passing them from a bash script. I was doing something like: (passing in a list of directories from command line to python) python main.py --result_dir "folder/dir_1, folder/dir_2" And in the python script main.py, parse the list of strings and on… result_dir_list = [f for f in result_dir.split(',')] # some operations following For now the code doesn’t work....

When I have to show a series of experiment results plottings, I used to use Meitu (a phone photoshop app) to first airdrop all images to my iphone, concatenate all the images, and them airdrop back to my mac. Not anymore now I got my hands on Imagemagick (https://imagemagick.org/). ImageMagick® is a free, open-source software suite, used for editing and manipulating digital images. It can be used to create, edit, compose, or convert bitmap images, and supports a wide range of file formats, including JPEG, PNG, GIF, TIFF, and Ultra HDR....

It all began when I stumbled upon a surprising revelation—some people, including legendary pianist Glenn Gould, weren’t fans of Mozart. I was skeptical and maybe a little defensive at first—like come on, how dare him? Ready to sabotage his argument and him, I decided to first watch his infamous television lecture, How Mozart Became a Bad Composer. But instead of finding material for a rebuttal, I discovered Gould’s opinion was a nuanced, masterful analysis—a critical gem in musical discourse....

It was not only Mozart that Glenn Gould clashed with: Leonard Bernstein with Glenn Gould. Photo by Don Hunstein, 1957; Courtesy of Sony Classical [Glenn Gould’s] April 1962 performance of Brahms’ first piano concerto, with the New York Philharmonic and Leonard Bernstein conducting, gave rise to an extraordinary situation in which Mr. Bernstein disagreed with Gould’s interpretation so vehemently that he felt it necessary to warn the audience beforehand. (Cait Miller)...

In Glenn Gould’s critical commentary on Mozart’s especially late piano concerti, he nevertheless adores Mozart’s early works: In his early works Mozart came very close to realizing the possibilities for experiment that would exist within even the most stylized form. His early sonatas concertos and Symphonies were extraordinarily flexible and inventive to a degree that he never quite equaled later on. My Mozart preference is for the work of his teenage years and as far as the piano sonatas are concerned those which he wrote during and shortly after his visit to Paris, which took place during his 22 year....

So, what is the concerto that Glenn Gould criticized so harshly? It’s Mozart’s Piano Concerto No. 24 in C minor (K.491). Mozart composed K.491 during the winter of 1785–86 (FYI, Mozart was 30 then and he died five years later), a period when he was also devoting to the creation of his late operatic masterpieces, such as Le Nozze di Figaro, Don Giovanni, and later Die Zauberflöte (in other words, concerti appointments are the composition chores he was possibly trying to get over with)....
