SuperDuper Rebuilt for the Modern Era
SuperDuper has been an incredible tool for backing up your Mac for a long time, but like most apps that last 22 years, things change. Developer David Nanian has launched a new version that is ready for the next 22 years. He writes: Back in 2007, I designed what was intended to be SuperDuper v3.0. It was a rewrite that greatly expanded its capabilities while retaining its essence. But, in those days, it just wasn’t possible for us to implement those grand plans. The new UI was much more complex, the logic more elaborate, and the systems we had then didn’t support the things needed to make it a reality without a lot of complex coding we didn’t have time for.

SpaceXAI to Remove ‘Temporary’ Gas Turbines From North Mississippi Site, Replacing Them With Permanent Models https://512pixels.net/2026/07/spacexai-to-replace-gas-turbines-southaven/
SpaceXAI to Remove ‘Temporary’ Gas Turbines From North Mississippi Site, Replacing Them With Permanent Models
Right across the state line from the ever-expanding Colossus II site is 2875 Stanton Road, home to a fleet of gas-burning turbines that generate electricity to keep SpaceXAI (and its customers) online. The pushback in Southaven, Mississippi over the Stanton Road site has been growing. Just this weekend, there was a public event addressing the issue, hosted by the NAACP and State Rep. Justin J. Pearson. Tonight, the company announced (in a statement that was also emailed to members of the press, including yours truly) that it will be removing its temporary turbines over the next year:

Impeccable Timing
OpenAI, in an unsigned announcement: Health in ChatGPT is launching to U.S. users. You can choose to securely connect Apple Health and supported medical records so ChatGPT can help you understand your information in context, keep track of what has changed, and have more informed, personalized conversations. The experience builds on feedback from early testers and gives you control over what you connect and when ChatGPT can use it. Every week, more than 300 million people turn to ChatGPT with health-related questions—from understanding a lab result and preparing for an appointment to making sense of what a doctor said and building a healthier routine. But the context behind those questions is often scattered across patient portals, medical records, apps, and wearables, making it difficult to see and act on the complete picture.

Google Announces Support for Nation’s Largest Solar Farm, Located in Arkansas
Google is building an AI data center in West Memphis, Arkansas, across the Mississippi River from Memphis. (I know, it’s a very original city name.) Google joins SpaceXAI and others in the Mid-South for cheap land and abundant water, but it faces the same core challenges — mainly, how to feed its huge collection of power-hungry hardware. When the project was announced, details about power generation were sparse. Today, we know a bit more. Will Conkling and Christopher Scott at Google:

OpenAI Rumored to be Making a Smart Speaker https://512pixels.net/2026/07/openai-speaker-gurman/
OpenAI Rumored to be Making a Smart Speaker
Mark Gurman, writing at Bloomberg: OpenAI’s much-anticipated push into consumer devices is slated to begin with a mobile, screen-free smart speaker designed to be a new type of home computer for the AI era, according to people familiar with the matter. The product — still under development — is meant to serve as a humanlike AI companion that lives in the home, said the people, who asked not to be identified because the project hasn’t been announced. It will help control smart-home appliances, play media, answer questions, respond to messages and tap into the range of capabilities offered by OpenAI’s ChatGPT, they said.

ArtfulType, a Markdown Editor for 68k Macs
Sean Malseed over at Action Retro has shipped something pretty cool: a Markdown editor for 68k Macs named ArtfulType: A distraction-free Markdown writing app for classic 68k Macintosh computers (System 6/7), built to run from a BlueSCSI device on a Mac Plus or similar compact Mac. He has a video walking through it, including how it was built (with the help of Claude Code) and how you can move data on and off older machines:

EveryMac Turns 30
Anyone who dabbles in Apple history probably has EveryMac.com bookmarked, and today it celebrates a milestone: On July 2, 1996, EveryMac.com launched. Thirty years is a long time – and a great deal has changed since then – but what has not changed is that EveryMac.com has been there to provide you with detailed info on every Mac from the original 128k to the current line. Thank you very much for your support through the years.

Om Malik’s family: Om Malik passed away on June 24, 2026, at Stanford Hospital after a long health journey with his heart. He was surrounded by family and friends. I’ve read Om’s writing since before starting this site over 17 years ago. It is hard to believe he won’t be lighting up my RSS reader anymore.

On Apple’s Pending Price Increases
John Gruber, writing about Apple’s pending price increases: I won a steak dinner from my Dithering cohost Ben Thompson, betting that Apple would not raise the prices on RAM when they introduced the M5 Pro and M5 Max MacBook Pros in March, largely on the basis that Apple considers the pricing part of the product’s brand. For the same reason, I also do not think they’re going to raise the prices of existing products mid-cycle. I think Cook’s warning is about the fall, starting with the iPhones 18 Pro and the folding “Ultra” in September, and he issued the warning months early just to make the bad news “old news” by the time September gets here.

SpaceX Recommits to Memphis Water Treatment Plant https://512pixels.net/2026/06/spacex-recommits-to-memphis-water-treatment-plant/
SpaceX Recommits to Memphis Water Treatment Plant
Memphis Mayor Paul Young: Had a productive meeting with SpaceXAI President Michael Nicolls on Monday. In the meeting they committed to resuming construction on the recycled wastewater treatment facility no later than Q1 2027. This facility will offset water usage from both SpaceXAI and TVA. Our engagement that led to this commitment will continue until the facility is complete. Samuel Hardiman, for The Daily Memphian: The facility was expected to treat wastewater from the City of Memphis’ nearby TE Maxson Wastewater Treatment Plant and turn it into a suitable industrial coolant, replacing the hundreds of thousands of gallons of freshwater the company uses each day. In February, it used 840,000 gallons of water a day, according to bills obtained by Protect Our Aquifer and provided to The Daily Memphian.
