This paper tests #GPT-5, Gemini 2.5 Pro, Claude Sonnet 4.5 & Grok 4 on every SCOTUS argued case from OT 2025. Accuracy looked good until you realise most of it just reflected the Court's usual ideological alignment, not actual legal analysis. spkl.io/633247zQpk #AI #LegalTech

Years ago I had a boss who explained, "no one reads emails." I thought this was harsh at the time. I have, however, come to accept it as a good 1st-order approximation. See also, this disclaimer has been linked in my email signature for ~10yrs, & only 1 person has ever commented.

Last month @thefordon.bsky.social, @jenwon.bsky.social, and I got to present at CALI Con on vibe coding for Legal Ed., and the video just went live. Enjoy. Note: this is partially a behind the scenes look at how I made some of the simulations for my algos & bias lesson (quoted thread).

1/ There has never been a more concentrated distillation of my teaching than this lesson: Algos, Bias, Due Process, & You. It is the apotheosis of what I do. I very much hope you enjoy it, share it, and make bits of it your own.

Goodnight, and good luck from the mountains.

It used to be that I'd skip over long threads or worse yet save them to come back to. Now I just unroll them with this simple tool. Case in point: colarusso.github.io/bluesky-thre... Also, useful if I want to capture the content of a long thread I wrote.

More thoughts on the AI / law school discourse. I'm trying to pinpoint the problem(s) we are trying to solve. Is the problem AI or is it that AI is revealing to us deeply rooted issues with law school education? I suspect the latter.🧵

A while back I was talking Emily Dickinson with my Mom, and she started reciting this poem from memory, having memorized it more than 50 years earlier. Seeing it today reminded me of that. I ❤️ this bot.

I've had a "productive" vacation. Not only did I get to do some painting, but I was able to overhaul my personal website www.davidcolarusso.com. Mostly, it's a collection of watercolors & photos, with a dash of videos and video games.

Upon exiting the shower, where I play my music on a Bluetooth speaker, perhaps a bit too loudly, the 12yo asked, “Have you been listening to Hamilton on repeat for like five days?”

Spotted on this evening’s walk, a double rainbow! 🌈

A vivid double rainbow arches across a gray storm sky above a forest of tall pine and leafy deciduous trees. The brighter primary rainbow rises behind the treetops, while a fainter secondary rainbow is visible above it. Sunlight illuminates the lush green foliage in the foreground, creating a striking contrast with the dark, rain-filled clouds overhead.

One benefit of perpetual reboots: Thanks to #StrangeNewWorlds, the youths still know who Spock is, even if they’re unfamiliar with the work of Ethan Gregory Peck’s grandfather.

Close-up of an Ethan Gregory Peck as Spock in a blue uniform with pointed ears and straight-cut black hair, standing on the bridge. Red and orange control panels glow in the background, while dramatic blue and red lighting illuminates his face as he looks off to the side with a focused, analytical expression.

Black-and-white portrait of a Gregory Peck in a pinstripe suit, white shirt, and dark tie seated among an audience. He faces slightly upward with a composed, attentive expression, while other people in the background are softly out of focus.

17 summers ago, we hiked out to this point to watch the sunset, and I asked her to marry me. 🥰 This was the view last night.

Sunset over sweeping white gypsum sand dunes, with soft footprints crossing the foreground. The sun sits just below a long band of dark clouds, sending golden rays upward and outward across the sky. Layered blue-gray mountain silhouettes stretch along the horizon, while scattered clouds glow with warm light along their edges. The gently rolling dunes, shaded in cool blue tones, create a peaceful, expansive desert landscape with dramatic light and shadow.

I saw "The Movie," and I really enjoyed it. Nolan found a way to be both true to the text and to say something new that speaks directly to the moment we live in. If you're on the fence, see it in the theater.

Tonight we played the 7yo’s new board game: Narwhal Dance Party. Each player gets a narwhal sticker as a piece and draws a card to move. The majority of cards are variations on “[move] n spaces,” but sometimes there are special cards like “dance party” where everyone moves forward 2 spaces.

A child’s hand wearing a colorful beaded bracelet reaches toward a stack of homemade game cards placed on a hand-drawn board game. The board, drawn on white paper with thick black outlines, features looping paths colored purple, green, pink, and yellow, with spaces marked by circles and decorated with small character stickers. One visible card reads “7 Spaces.” The game rests on a wooden table, suggesting a creative homemade board game in progress or being played.

Two handmade board game cards lie on a wooden table above four colorful narwhal character tokens cut from stickers. The left card, decorated with a small disco ball drawing, reads, “Dance Party – 2 Spaces Forward.” The right card, also topped with a disco ball, reads, “Dance Party – 2 Spaces,” but is clearly written by a child with “Spaces” misspelled. Below them are four cheerful narwhal cutouts in party-themed costumes: a narwhal dressed as a wizard, a narwhal wearing sunglasses beside a disco ball, a narwhal with a hula hoop, and a narwhal with flowers and a pink scarf.

I’ve spent several hours this week at the local weaving school watching while the 7yo learned how to make her first weaving project—a handbag. Only one more session before she finishes. I’ve really enjoyed hanging out and chatting with the other weavers, great community.

A child works at a tabletop wooden weaving loom, guiding pale blue yarn through the warp while holding a wooden shuttle. A partially completed fabric with a blue herringbone pattern and dark blue, tan, and white stripes stretches across the loom. The child wears a light blue T-shirt with a bear graphic and a colorful beaded bracelet. Wooden chairs and tables in the softly blurred background.

Earlier this week I learned the 12yo didn’t know what a pinball machine was. Don’t worry. We have rectified the situation. Tonight he and his sister learned firsthand.

A child stands playing a brightly lit Pulp Fiction pinball machine in a dark arcade. The glowing backglass artwork features characters from the film, while neighboring pinball machines themed to Rush and The Phantom of the Opera add colorful lights on either side. Above the machines, a large skeleton decoration with glowing red eyes looms over the arcade, enhancing the playful, spooky atmosphere.

From last night’s evening stroll. Another sunset in the mountains.

Twilight view over a small mountain town with warmly lit storefronts and lodges lining a quiet main street. Above the rooftops, a dramatic thunderstorm spreads across the horizon, with towering dark clouds and a rain shaft illuminated by the last glow of sunset. High in the deepening blue sky, a thin crescent moon hangs alongside a bright planet.

Vacation achievement unlocked. It got cool enough we were able to rationalize s’mores.

An open-faced s’more sits on a bright orange plate atop a wooden table. One graham cracker is topped with a large toasted marshmallow, browned and slightly charred on one side, while the other holds a three-segment Hershey’s chocolate bar. The ingredients are arranged separately, ready to be pressed together into a melted s’more.

Screenshot of a weather app showing current conditions for Cloudcroft. Large white text reads “Cloudcroft” with the current temperature of 64°. The forecast says “Thunderstorm”, with a high of 66° and a low of 53°. The background features dark gray storm clouds with animated-style falling rain.

Close-up of a large marshmallow on a roasting stick, lightly toasted to a golden brown, held in front of an open wood-burning stove with glowing embers. In the background, two people extend roasting sticks into the fire, with additional marshmallows warming over the coals. The stone hearth and cast-iron stove create a cozy cabin atmosphere.

We’re only a day away from launch, here’s hoping the 7 & 12yo’s new builds will be ready by then and that the skies stay clear. 🤞

Partially assembled model rockets rests on a cluttered worktable surrounded by hobby supplies, including wood fins, glue, a craft knife, ruler, instruction sheets, and small construction parts. A white rocket body features attached balsa wood fins and a nose cone placed alongside, showing the project mid-build in a home workspace.

I fully endorse the alt text for this comic, & I don't think sharing it is a spoiler, "All discussions of daylight saving time policy are doomed by a mix of contradictory, inconsistent, and impossible preferences, which is why I think the only thing we can really hope to do is to make it worse."

When the kids saw these hummingbird feeders you could wear as rings, I really didn’t think they were going to work.

A child in an orange shirt holds a small red flower-shaped hummingbird feeder on an outstretched hand while a hummingbird hovers inches away, extending its long bill to feed. The scene takes place on a wooden porch surrounded by pine trees, with cabins softly blurred in the background.

Apollo 11 launched 57 years ago today on July 16, 1969. Many years later, my kids and I made this stop motion film. We hope you enjoy it and remember always to look up and that anything is possible when we work together.
