On March 15, 2026, China’s annual Consumer Rights Gala — our most-watched consumer protection broadcast — investigated a business called GEO (Generative Engine Optimization). GEO providers charge clients to plant promotional content across the internet so that AI chatbots pick it up and recommend their products as if giving objective advice. So how do you ‘poison’ a LLM? CCTV reporters contacted multiple GEO firms. One, led by a manager surnamed Wang, claimed 200+ clients across industries within its first year. Wang explained the method: they produce advertorial articles on behalf of clients and publish them across platforms where AI models crawl and index content. Because AI algorithms update weekly, Wang said, they must continuously publish fresh content — “feed it, massively feed it” — to maintain rankings. ...

St Louis Symphony Orchestra’s March 14 concert: Anna Sułkowska-Migoń, conductor Leila Josefowicz, violin soloist Grażyna Bacewicz (1909–69) | Overture Alban Berg (1885–1935) | Violin Concerto Nikolai Rimsky-Korsakov (1844–1908) | Scheherazade The first half of the program leaned toward twentieth-century repertoire—classical bundling, in a sense, and a familiar programming strategy. From a purely practical perspective, orchestras could probably maximize revenue by programming Beethoven every night. Yet the willingness to rotate contemporary and lesser-known works into the repertoire reflects something more meaningful than an artistic director’s intellectual display. It signals a genuine commitment to exploration within the classical tradition. Programming like this keeps the repertoire alive and expanding; the music is treated not as a museum artifact but as a living practice. Art comes first, and the economics follow. ...

I took an Amtrak to St Louis to hear their orchestra perform Scheherazade. It was a peculiar kind of freedom, with a sense of desolation and solitude.

My friend invited me to a Friday evening concert at the Logan Center for the Arts at the University of Chicago. The program, at least on paper, looked fashionable: contemporary works, a celebrated jazz pianist–composer, and the ever-adventurous Third Coast Percussion. I read the program carefully—and still wasn’t quite sure what to expect… The first half of the concert belonged entirely to the percussionists. Happy. Third Coast Percussion opened with an arrangement of Etude No. 1 by Tigran Hamasyan (the composer-pianist), followed by Jessie Montgomery’s Lady Justice / Black Justice, The Song, and the world premiere of Sérgio Assad’s Orion, a five-movement work inspired by the stars of the Orion constellation. ...

One of the most insightful essays I’ve read for years: City and Ambition May 2008 | https://paulgraham.com/cities.html#f5n The essay is so condensed and well organized that I dare not quote it partly — and it’s definitely worthwhile to read it in full glory. Notably though, a comment about art is particularly interesting Paris was once a great intellectual center. If you went there in 1300, it might have sent the message Cambridge does now. But I tried living there for a bit last year, and the ambitions of the inhabitants are not intellectual ones. The message Paris sends now is: do things with style. I liked that, actually. Paris is the only city I’ve lived in where people genuinely cared about art. In America only a few rich people buy original art, and even the more sophisticated ones rarely get past judging it by the brand name of the artist. But looking through windows at dusk in Paris you can see that people there actually care what paintings look like. Visually, Paris has the best eavesdropping I know. [5] ...

The benefit of becoming a CSO donor: Bachtrak ranked CSO as the world busiest orchestra of 2025 — they presented the most concerts within a calendar year. The CSO has shows almost every week Thu-Sat. According to a college night interview, they rehearse every Wednesday and Thursday mornings before the first performance kick off Thursday night, weekly. Being a professional orchestra musician is actually tough job. Winds who are counting bars are not necessarily 100% happy, I guarantee you. And when the first violin mess up during rehearsal, though not all conductors yell, but even hearing the Jakub Hrůša pointing out the mistake is quite stressful. ...

A Bite of China is a remarkable documentary about Chinese food. In a sense, good food and good grades are the two pillars of success in our society. As we take food seriously, the soundtrack to A Bite of China draws effectively on classical idioms to convey the philosophical depth and cultural richness of Chinese cuisine. Eg. Season 1 Episode 3: the first few seconds of the opening flute melody has almost become a music motif that means fooooood in China ...

A loosely organized catalogue of macroeconomics lecture notes of Spring 2026 — neoclassical growth, structural transformation, misallocation, heterogeneous agents, and business cycles.

Benjamin Grosvenor hit the CSO Sunday 3pm stage with a program that speaks different musical languages: Beethoven’s Moonlight Sonata, Schumann’s Fantasy in C Major (Op. 17), Scriabin’s Sonata No 2 (Op. 19) and Ravel’s Gaspard de la nuit. Benjamin Grosvenor plays Ravel really well. I hear the poetic vibe and surreal magic. Though you don’t need a PhD in music to appreciate the beauty of Moonlight Sonata, and despite the program are all popular composer’s signature work — with a bit of learning, one can you hear the difference of how composers speak through music, especially with the contrasting program. ...

The amazing Pinchas Zukerman, Amanda Forsyth and Michael Stephen Brown brings a night of exquisite classic trios to the well-educated-but-enthusiastically-clapping-between-mvts Chicago audience on a cozy Saturday night. Mendelssohn Piano Trio No. 1 Higdon Pale Yellow from Piano Trio Dvořák Dumky for Piano, Violin and Cello, Op. 90 The music moved me. And the program is nice — just pure beauty, elegance and joy, no need for an avant garde piece to prove anything this time. ...
