Our reading group covered this paper today: Local hedging approximately solves Pandora’s box problems with nonobligatory inspection Ziv Scully and Laura Doval (2025) | Link: https://arxiv.org/pdf/2410.19011 Abstract: We consider search problems with nonobligatory inspection and single-item or combinatorial selection. A decision maker is presented with a number of items, each of which contains an unknown price, and can pay an inspection cost to observe the item’s price before selecting it. Under single-item selection, the decision maker must select one item; under combinatorial selection, the decision maker must select a set of items that satisfies certain constraints....

I’m practicing the adapted flute solo piece for Lensky’s Aria from Tchaivkosky’s Opera Eugene Onegin. Here’s the background check for this piece: The opera has three acts and Lensky’s aria takes place near the end of Act II: Act I: Tatyana, a bookish and romantic young woman, falls in love with the dashing but aloof Eugene Onegin, a friend of the poet Vladimir Lensky. She writes Onegin a heartfelt letter confessing her feelings....

I first encountered matrix completion duing undergrad in Advance Operations course. So I thought it was history well-solved problem. Turns out well, amazing papers still emerge over the past years: Matrix Estimation by Universal Singular Value Thresholding (USVT) Sourav Chatterjee The Annals of Statistics (2015) Consider the problem of estimating the entries of a large matrix, when the observed entries are noisy versions of a small random fraction of the original entries....

This piece comes from Chuai Lam’s casual writings, likely penned between 2020 and 2022. Reading his reflections from that turbulent period evokes a strong sense of déjà vu — a vivid reminder of the time when I often looked skyward, longing for travel and the wonders of the world beyond. Chuai Lam reminisces about journeys, people, and — naturally — unforgettable meals. There were countless places he hoped to revisit: Barcelona and Gaudí among them....

Flute shines brightest in chamber music — not that the ethereal flute solo in Carmen Intermezzo isn’t already fantastic — but orchestral solos are still somewhat constrained, where the flute serves as one beautiful component within a larger structure. Chamber music, on the other hand, gives the instrument the full freedom to express, flex, dance. And Pahud elevates the entire performance with his charisma, precision, and deep musical understanding. If you ever get the chance, don’t miss him live....

The concert hall hosted a public workshop featuring the Berlin Philharmonic Quartet. I hadn’t realized they were inviting students and young musicians from local conservatories to perform live. What a rare and generous and scary opportunity to play for world-class artists. And who would pass up a free masterclass? Especially one led by musicians who live and breathe chamber music. The joy of deep musical conversation was more than enough to offset the… shall we say, colorful distractions of the event’s host — whose long-winded, self-important commentary made many of us long for the mute button....

Emmanuel Pahud, in my eyes, is the greatest flutist in the world. He’s the principal flute of the Berlin Philharmonic — a position that speaks volumes — and this summer, he’s on tour in China. Two concerts and one workshop. I’m attending all three. As a flutist, I can’t help but reflect a little on his influence on me. I started listening to Pahud’s recordings back in high school, during the pandemic....

My Shostakovich-fan friend got really excited recently cause, the composer is about to enter public domain — 50 years after he passed away (August 9 1975). He was like “all his scores are going public, and I can’t wait to see the original manuscript of his Waltz No. 2”. Huh? Well not exactly. Cause first, in most countries, copyright protection lasts for 70 years after the death of the author. Second, most jurisdictions apply public domain changes on January 1st of the year following the 70th anniversary of the death....

Recently I noticed a weirdly popular TikTok trend: It’s gone viral internationally The original choreography is by 不齐舞团: Watch on YouTube, based on a Chinese-Cantonese rap song: Its rise to fame isn’t just algorithmic luck. The song taps into the mindset of a generation of young people in China today — caught in between. They’re not fully grounded in traditional culture, yet feel unable to move upward either. There’s a great article that explores this cultural moment:...
