Mr. Husted has cast the argument over data centers as one in which progress is at stake. “I mean, you can go back to the bunny-ear antenna on your TV,” he said on a recent podcast. “You don’t need a data center. But if you’re connected to a wire, you’re using the data center.” Idiot.

Today would’ve been my father’s 95th birthday. In search of a better life, he came to America with only $2.43 and a Korean-English dictionary. He had no friends or family here. Like many immigrants, he dreamt of the promise of what this country could offer. Each day I work to honor his memory.

Temple roof details. Japan.
A vertical landscape photograph captures a striking seasonal juxtaposition of traditional Japanese architecture and nature at a historic temple complex. The tightly cropped, layered composition highlights the brilliant contrast between the enduring geometry of monumental wooden structures and the fleeting, fiery intensity of autumn foliage. By isolating the roofline against deep shadows, the image takes on a graphic, woodblock print-like quality, transforming a structural detail into a poetic meditation on kōyō (autumn leaf viewing).

The core of the image is anchored by a beautifully preserved section of a temple roof, showcasing classic East Asian ceramic tilework (kawara). Rhythmic rows of concave, grey-glaed pantiles create a corrugated texture across the slope, terminating at the eave line with a neat row of circular end tiles (tokoname-gawara). These round tile faces are stamped with traditional relief crests—likely a mon or temple insignia—which serve both a decorative and practical function by deflecting rainwater away from the underlying timber brackets. Directly beneath the eaves, the dark, weathered wooden support system of interlocking brackets and rafters emerges from dense shadow, underscoring the massive, hand-carved scale of Japan's sacred architecture.

Framing this architectural center are two magnificent branches of a Japanese maple tree (momiji), which bookend the composition from the top left and bottom left corners. The leaves are at the absolute peak of their autumnal transformation, rendered in a dense, fiery crimson red that appears almost incandescent against the dark, neutral tones of the building. The delicate, multi-lobed shapes of the maple leaves create a soft, intricate texture that softens the rigid, linear lines of the clay tiles.

Today marks 250 years since a small group of newspaper editors, farmers, and soldiers signed a document declaring our nation's independence — a truth that feels self-evident now but was revolutionary then.
What a privilege us Americans have, to live in a nation that every one of its inhabitants can shape. What an honor us New Yorkers have, to look out over our city's waters from the shores where so many Americans bravely entered their country for the first time.
Today and all days, let us remember that patriotism is not pretending our nation is without flaws. Patriotism is every act of righteous dissent — because loving our country means fighting for the best version of it.
Happy Fourth of July, New York City.
