Feel like your tabs have tabs? (Sponsor)

Developer tool sprawl is real. You've got one tab for logs, another for metrics, half a dozen for cloud services, and somewhere in there is the code you're actually trying to ship.

🫣 Stop playing hide-and-seek with your tools. Microsoft Azure brings together everything you need to build and run software in a single workspace.

Goodbye, hunting for the right dashboard. Hello, one unified view—and a faster path to innovation.

Elon Musk Megatrial Kicks Off Second Week With Scrutiny of OpenAI Exec's Finances (8 minute read)

OpenAI president Greg Brockman took the stand on Monday. Two days before the trial, Elon Musk had messaged Brockman to gauge his interest in settling the case. Brockman suggested that both sides drop their claims, but Musk responded by saying that Brockman and Sam Altman would be the most hated men in America by the end of the week. Musk's lawyers are attempting to paint Brockman as motivated by money at the expense of OpenAI's nonprofit mission.

Amazon Built a Massive Supply Chain for Itself. Now It's for Hire (7 minute read)

Amazon has launched Amazon Supply Chain Services, a centralized place for companies to hire Amazon for services such as fulfillment, ocean and air shipping, and truck transportation. The offering puts Amazon in competition with transportation and warehousing giants such as DSV and DHL. The global market for third-party logistics is estimated to be more than $1.3 trillion. The move is a bet that Amazon can do for logistics what Amazon Web Services did for cloud computing.

SpaceX Breaks Ground on Solar Fab to Power Orbital Data Centers (3 minute read)

SpaceX is constructing one of the world's most advanced solar cell factories in Bastrop, Texas. The company is vertically integrating the entire fabrication process to produce highly specialized aerospace-grade solar cells. Vertical integration allows SpaceX to insulate itself from global supply chain vulnerabilities while also giving it total control over the physical limits of solar cell efficiency and mass. SpaceX needs a continuous, high-volume supply of bespoke solar arrays to successfully pull off its plans of deploying an orbital cloud network capable of handling AI workloads.

The Roomba Guy's Second Act: A Robot You'll Want to Snuggle (8 minute read)

Familiar Machines & Magic, a startup headed by Colin Angle, the former CEO of the company that invented the Roomba, has unveiled a robot designed by former Disney Imagineers to be cute and appealing. The Familiar is an emotionally intelligent robot trained to respond appropriately to tone of voice, body language, and overall vibe. The company will market the robot to people who want to monitor their loved ones, and it is also keen to sell Familiars to people who would like to support their own well-being. The robot is still in an early prototype phase, so there is no information on pricing or availability.

📊 How many dashboards is too many? (Sponsor)

Every new monitoring tool, service, or "quick integration" adds another dashboard to the pile—and before you know it, you're spending more time switching between tools than actually building. With Microsoft Azure, your entire stack lives in one workspace: infrastructure, data, AI, and more. See how Azure brings it all together →

Formatting an entire 25 million line codebase overnight: the rubyfmt story (15 minute read)

Stripe runs the world's largest Ruby codebase. The pain of not having an auto-formatter was visible in how its engineers worked. In 2022, the company set two engineers from its infrastructure team to work full-time on rubyfmt, a tool that is currently being used to format 100% of Stripe's 42 million lines of Ruby. This post tells the story of how rubyfmt came to be.

Redis array type: short story of a long development (5 minute read)

The PR for a new Array data type for Redis took four months to create using AI assistance. AI tools allowed the developer working on the code to venture into a level of complexity they would have otherwise skipped. They helped make tasks easier and less tedious while also providing a virtual workforce that could reveal bugs in complicated algorithms.

GameStop Offers to Buy eBay for $56 Billion (7 minute read)

GameStop has made an unsolicited offer to buy eBay for $56 billion, a roughly 20% premium to the company's stock closing price on Friday. GameStop is a much smaller company than eBay and is currently valued at around $12 billion. The company has around $9 billion in cash and a commitment letter from TD Bank to provide up to $20 billion in debt financing to help make the deal possible, but it is unknown how the company will come up with the rest of the money.

AI for Bio has a Fuzzy API problem (20 minute read)

Biology is a uniquely hard application domain for machine learning. Drug discovery doesn't have the kind of clean feedback loops and clean interfaces that make modern ML so powerful elsewhere. Software has clean APIs, and when things break, you can usually trace the failure to a bug and fix the code. Biology's outputs are a lot fuzzier as there are many caveats at every step of the process.
