"Rendering Doom in a database is obviously a bad idea," Lukas Vogel writes in a lengthy blog post explaining how exactly he managed to render Doom using an SQL database.

OK, that's not entirely accurate. The SQLDoom project uses a small Python client to handle input and output, drive the game's timing, and display each frame to the screen. Behind that, a series of CedarDB tables tracks the game geometry and state, while about 1,300 lines of SQL queries spread across 89 common table expressions implement the game logic and generate 35 bitmap framebuffers per second.

In this, SQLDoom is a major improvement over Vogel's previous DoomQL project, which last year set out to build "a multiplayer Doom-like shooter entirely in SQL." Unfortunately, that effort ended up with raycasting-based, grayscale ASCII graphics that were more akin to the simplistic 90-degree-angled maps of Wolfenstein 3D. The newer SQLDoom, on the other hand, generates full-color 640x480 frames that look like they could have come from the original Doom executable.

My family has spent four summers participating in demand response programs whereby utility companies pay customers to reduce energy use on the hottest summer days. Most summers have involved carefully precooling our New York City apartment before switching off the air conditioners and sweating it out during the designated demand response periods.

But this year, we kept our window air conditioners running throughout a heat dome event that drove daytime temperatures into the triple digits and made the nights oppressively hot. The difference was that we powered the air conditioners through two household batteries tucked away unobtrusively in the corners of our living room and bedroom.

We were among about 1,000 New York City households that took part in a free and growing program offered by the local startup Every Electric. The company’s proposition is simple: Get one or more batteries delivered to your home, plug the batteries into a standard wall electrical outlet, and then plug your window air conditioners into the batteries. Households can keep running air conditioners as usual during peak demand periods while also earning money through the local demand response program with the utility company Con Edison.

Guided Vision is launching in Gemini Live on compatible Android devices today to use AI to give real-time audio descriptions of anything you point your phone's camera at. By sharing your camera in Gemini Live, you can have Google's AI help with things like reading small text, describing your surroundings, finding or identifying objects around you, and describing details on specific objects.

Like the VoiceOver Live Recognition feature Apple has added to the iPhone and Vision Pro, it's designed for people who are blind, have low vision, or want assistance in specific situations. In addition to the Gemini app, Guided Vision is also available …

Both Lee, the site's managing editor, and Sutrich confirmed that all remaining staff were laid off.

The former staffers weren't told whether the site would shut down. Today, …

Normally, we try to update you quarterly on what's going on with the US electric grid since it provides a nice view of developing trends and smooths out some month-to-month randomness. Unfortunately, I was out of the office when last month's data was released, so this will be a seven-month update on 2026 trends.

The top line item is that energy use is continuing to rise, albeit not as quickly as headlines about data centers might lead people to believe. Beyond data centers, there's a growing electrification—things like EVs and heat pumps—that is shifting energy demands onto the grid. Despite all of this, electricity use has risen by only 2 percent compared to the same period last year. At this time the previous year, demand had risen by 3 percent compared to the year prior.

Some of this may be due to continued improvements in efficiency, which had largely kept electricity demand stable throughout the early 2000s. And some of it may be because more data centers are generating their own power so that demand doesn't show up on the grid. So far, the growth in demand hasn't reached apocalyptic levels.

Virtually every Android device comes with the Play Store preloaded, but there are other ways to get apps. F-Droid bills itself as a community-driven source for free and open source Android apps, but its official app store has gone 10 years without a major update. That's finally changing: After a multiyear effort, the team has just announced F-Droid 2.0 is rolling out.

The new F-Droid client was redesigned from scratch in Kotlin Compose, which is the standard for modern Android apps. This makes the store much more responsive, and there's optional support for Android's Material theming. The interface has also been cleaned up considerably, making the most important functions easier to access and hiding some others in overflow menus.

While the new F-Droid looks nicer, the update was largely about making it easier to find and install apps. When F-Droid first appeared, there wasn't much to see, but now it has thousands of open source apps. Unlike the Play Store, F-Droid doesn't track your taps and installs to push ads and suggestions—it helps you find things and gets out of the way.

In late 2010, an up-and-coming Google executive named Sundar Pichai took the stage in front of a bunch of reporters and explained that Google had a big new idea about laptops. In the future, he said, the only thing you'd need on your computer was a web browser - that was where all your apps, data, and connections would live going forward. Your computer didn't need much storage, Pichai explained, or any fancy hardware, because the cloud would do the work. The software designed for these new laptops, Chrome OS, was an enormous bet that the web would eventually overtake everything.

Chrome OS (which eventually became ChromeOS) has been, in many …

There are a few things about using a Googlebook that immediately feel just right. The hardware is polished (since it's based on current laptops). The OS is familiar (if you've ever used a Chromebook). But most impressive, it integrates your Android phone with your PC so they feel more like one device. It's the culmination of a series of new ideas that blur the two devices together. After my first look, I went from doubtful to excited by the prospect of Google pulling it all off.

After an initial barebones announcement in May, Google is finally launching Googlebooks - its new line of Android-based laptops. The initial five Googlebook models …
