I’ve been working on Squawk for a while, it’s a linter for PostgreSQL, and it now uses a handmade parser. So let’s explore some interesting bits from the Postgres grammar. Custom Operators Very few operators are defined in the grammar itself and lots of Postgres features rely on custom operators. For example, Postgres uses <-> for comparing geometric types, along with a whole host of others: ## , @-@ , # , @> , <@> , &< , &> , |>> , |<< , <^ , >^ , ?- , ?| , ?|| , ~= . Note: custom operator

Minimal Boolean Formulas Posted on Wednesday, May 18, 2011. 28. That's the minimum number of AND or OR operators you need in order to write any Boolean function of five variables. Alex Healy and I computed that in April 2010. Until then, I believe no one had ever known that little fact. This post describes how we computed it and how we almost got scooped by Knuth's Volume 4A which considers the problem for AND, OR, and XOR. A Naive Brute Force Approach Any Boolean function of two variables ca

Alamo Drafthouse is working on a multi-year alliance with Toho that will bring with it new merch and special Godzilla programming—and it’s kicking off today with the opening of a new Drafthouse theater in California that will become the world’s first fully Godzilla-themed cinema. io9 can exclusively reveal the first details about Drafthouse and Toho’s new partnership, which formally kicks off with today’s opening of the Alamo Drafthouse Valley Fair, at Westfield Valley Fair in Santa Clara, Cali
Low WiFi in a large house can be quite frustrating, particularly when your ISP router is not powerful enough to cover all parts of it. Instead of relying on an average box that has a tendency of creating dead spots and lagging connections, it is worth investing in a more powerful system from a trusted brand like TP-Link. One of their best-selling devices, the 3-pack TP-Link Deco AX3000 WiFi 6 mesh system (deco x55) is currently selling at an all-time low price of $149, down from $199 previously
Over the weekend, OpenAI removed all promo materials related to its $6.5 billion buddy-buddy partnership with Apple design legend Jony Ive and their still unannounced AI-centric device. This wasn’t a falling out between the two titans in tech, but rather the result of something altogether stranger. The nixed webpages and videos are due to a trademark lawsuit filed by a separate startup, iyO, which is seemingly miffed about the companies names being a single letter apart. On July 20, California
So far the marketing for Weapons is looking like 2025’s slightly more accessible answer to last year’s Longlegs: freaky and distressing, and promising exponentially more of the same from the feature itself. A first trailer gave a little more insight into the movie’s plot, and a retro-styled website plays up its true-crime angle. Now Weapons is back with a second clip to set the dread-filled mood even more. We see a bewildered teacher (Julia Garner) being blamed for a class of missing kids, with
Weak vacuum suction is a nightmare in real, especially when you want a spotless home without a hefty cost. Dyson cordless vacuums have a wide range of options, and currently three best-sellers are available at Amazon’s all-time lowest prices.

Got your sights set on the next iPhone? The latest colorful rumor that came out last weekend is that the iPhone 17 base model could come in purple or green. In a post on X, well-known leaker Majin Bu teased the potential new colors for the iPhone, saying that Apple may just choose purple. And earlier this month, there were rumors of sky blue being added to the color lineup, too. We'll get to all of that in a minute. While the rumored iPhone 17 may get a new camera design and faster charging ca
For the second time in two months, United Launch Alliance sent a batch of 27 broadband Internet satellites into orbit for Amazon on Monday morning. Just like the last flight on April 28, an Atlas V rocket lifted off from Cape Canaveral, Florida, and delivered Amazon's satellites into an on-target orbit roughly 280 miles (450 kilometers) above Earth. This was the second launch of a full load of operational satellites for Amazon's Project Kuiper, a network envisioned to become a competitor to Spa
Last month, Microsoft released a modern remake of its classic MS-DOS Editor, bringing back a piece of computing history that first appeared in MS-DOS 5.0 back in 1991. The new open source tool, built with Rust and simply called "Edit," works on Windows, macOS, and—in a twist that would have seemed unlikely three decades ago—Linux. The cross-platform availability has delighted longtime users who never expected to see Microsoft's text editor running on their preferred operating system. "30 years
Elon Musk’s lawyers claimed that he “does not use a computer” in a Sunday court filing related to his lawsuit against Sam Altman and OpenAI. However, Musk has posted pictures or referred to his laptop on X several times in recent months, and public evidence suggests that he owns and appears to use at least one computer. Musk and his artificial intelligence startup xAI sued OpenAI in February 2024, alleging the company committed breach of contract by abandoning its founding agreement to develop

The House of Representatives has banned staff members from using WhatsApp on government devices, according to a report from Axios.

Microsoft is rolling out a new update to its Xbox Home UI that allows Xbox owners to pin apps and games on the homescreen. It’s part of a number of customization changes to the Xbox Home UI, including the ability to hide system apps and reduce the number of apps and games listed in the most recently used section.

In September, Apple launched its latest smartwatch, introducing the Apple Watch Series 10 alongside a black rendition of the Apple Watch Ultra 2. Each wearable has its own pros and cons, as does the second-gen Apple Watch SE, but the introduction of Apple’s newest wearables also means there are now more Apple Watch models on the market than ever before — and a lot more deals to be had. But with all of those options, which one should you pick? Generally speaking, you want to buy the newest watch
More invites to Amazon’s upgraded digital assistant, Alexa+, powered by generative AI, have been steadily rolling out. The service, first announced in February, now reaches over a million users, Amazon confirmed to TechCrunch on Monday. However, Alexa+ is not yet publicly available. Instead, Amazon has been working through its waitlist, sending out invites to those customers who originally signed up to test the service when it became available. Over the past several weeks, many people have shar
The big picture: According to the American Society of Civil Engineers, more than half of the 623,218 bridges in the US are in a state of significant deterioration. Getting them back in good standing would cost north of $191 billion – no small chunk of change. For researchers at MIT, finding a more cost-effective solution using modern technology is a worthy cause. Using a laser-based additive manufacturing technique called cold spray, the team successfully repaired a corroded section of a bridge
Development of the benchmark at HongShan began in 2022, following ChatGPT’s breakout success, as an internal tool for assessing which models are worth investing in. Since then, led by partner Gong Yuan, the team has steadily expanded the system, bringing in outside researchers and professionals to help refine it. As the project grew more sophisticated, they decided to release it to the public. Xbench approached the problem with two different systems. One is similar to traditional benchmarking:
Ryan Haines / Android Authority TL;DR Gemini is taking some inspiration from ChatGPT. There are now suggestion chips on Gemini’s homescreen. Google also appears to have made a tweak to the greeting text. Save for a brief, friendly greeting and text box at the bottom, Gemini’s homescreen is fairly empty. However, Google could fill up some of that unused space by taking an idea from one of its rivals. Authority Insights story on Android Authority. Discover You're reading anstory on Android Au
US congressional staffers have reportedly been told that they're no longer allowed to use WhatsApp on government devices. The House of Representatives' chief administrative officer (CAO) is said to have informed workers on Monday that the app — including the mobile, desktop and web-based versions — is not permitted on House-managed devices. "The Office of Cybersecurity has deemed WhatsApp a high risk to users due to the lack of transparency in how it protects user data, absence of stored data e
The U.S. Department of Homeland Security (DHS) warned over the weekend of escalating cyberattack risks by Iran-backed hacking groups and pro-Iranian hacktivists. This warning was issued as a National Terrorism Advisory System bulletin on Sunday and cautions that the Iranian conflict is causing a "heightened threat environment" in the United States, with "low-level" cyberattacks targeting networks in the U.S. likely. "The likelihood of violent extremists in the Homeland independently mobilizing

Jack Wallen / Elyse Betters Picaro / ZDNET I depend on virtual machines. With them, I can easily use and review any Linux distribution on the market. I can also deploy various services on my network. For example, I have an instance of InvoicePlane that runs as a virtual machine (and I use daily to bill clients). I've used virtual machines for all sorts of things, and they have made my life considerably better. One of the tools I use to run virtual machines is VirtualBox. This application makes
Jack Wallen / Elyse Betters Picaro / ZDNET Nearly everything you do on your desktop, laptop, phone, and tablet begins with a Domain Name System (DNS) query. Essentially, DNS turns domain names (such as ZDNET.com) into an IP address so web browsers and apps know where to get the information you want.
