Embedding User-Defined Indexes in Apache Parquet Files Posted on: Mon 14 July 2025 by Qi Zhu, Jigao Luo, and Andrew Lamb It’s a common misconception that Apache Parquet files are limited to basic Min/Max/Null Count statistics and Bloom filters, and that adding more advanced indexes requires changing the specification or creating a new file format. In fact, footer metadata and offset-based addressing already provide everything needed to embed user-defined index structures within Parquet files w
Elon Musk’s SpaceX is set to invest billions in his artificial intelligence company, and now he is hoping Tesla will do the same. Investors familiar with the matter told The Wall Street Journal that the rocket company SpaceX has agreed to invest a whopping $2 billion in xAI, the Musk-led firm behind the controversial large language model Grok. This investment makes up almost half of the $5 billion of equity that the AI company raised last month. Unsurprisingly, the richest man in the world isn

Tesla is on trial in Miami today in a case that accuses Elon Musk’s company of liability in a fatal crash involving Autopilot. The driver-assist system has come under scrutiny in the past for a number of fatal incidents, but Tesla has only rarely faced a jury trial over the question of whether Autopilot was at fault for som
Two years in, Threads is starting to look more and more like the most viable challenger to X. It passed 350 million monthly users earlier this year and Mark Zuckerberg has predicted it could be Meta's next billion-user app. But Threads still isn't sending much traffic to other websites, which could make the platform less appealing for creators, publishers and others whose businesses depend on non-Meta owned websites. According to Similarweb, a marketing intelligence firm, outbound referral traf

In the grim dark future of the 41st millennium, there is only war—and that kind of attitude invites a lot of yelling. Angry human yells, angry alien yells, angry daemonic yells, someone, somewhere is always yelling in the world of Warhammer 40,000. But in our own universe, there’s also been a lot of yelling about yelling as of late. Recently, Relic Entertainment announced that it would be reviving the classic original entry in the Warhammer 40K game series Dawn of War with a new remaster, clean

Published in the Nature Partnering Journal Aging, a new paper by researchers at Emory and Baylor's medical schools suggests that psilocybin, the active compound in psychedelic mushrooms — there are a range of species that produce it, but the best known is probably Pisolocybe cubensis — might extend the lifespans of both mi
Dozens of Gigabyte motherboard models run on UEFI firmware vulnerable to security issues that allow planting bootkit malware that is invisible to the operating system and can survive reinstalls. The vulnerabilities could allow attackers with local or remote admin permissions to execute arbitrary code in System Management Mode (SMM), an environment isolated from the operating system (OS) and with more privileges on the machine. Mechanisms running code below the OS have low-level hardware access

Campbell's Law (a variant of Goodhart's Law) states that the more a metric is used for social decision-making, the more it will be subject to corruption which distorts and corrupts not only the metric itself, but the very social processes it was meant to measure. Selection criteria for a position of authority are one example of such a metric. When selection criteria are opaque, it is difficult for them to become a target, preserving their utility as measures. For governance positions however, it
CNET's key takeaways The Windmill AC normally costs $349 for 6,000 BTUs, but you can often find it on sale on Windmill's website Amazon Home Depot Not only is the Windmill AC the easiest unit I've ever installed, it's the only AC unit I've tried that effectively kept my older and not well-insulated home cool during a heat wave. Bonus: It's actually stylish. Although, I still would have paid for an ugly one that works. Its normal price is higher than some other window AC units, but I've paid
An AI model launched last week appears to have shipped with an unexpected occasional behavior: checking what its owner thinks first. On Friday, independent AI researcher Simon Willison documented that xAI's new Grok 4 model searches for Elon Musk's opinions on X (formerly Twitter) when asked about controversial topics. The discovery comes just days after xAI launched Grok 4 amid controversy over an earlier version of the chatbot generating antisemitic outputs, including labeling itself as "Mech
The platform’s technical foundation centers on modeling infrastructure relationships in detail. The NetBox model encodes realistic relationships, such as an IP address’s provision on an interface, where the interface is on the switch, and where the switch sits in a rack. In addition, NetBox Labs has expanded the core platform with complementary products that address operational pain points while leveraging the central data repository. NetBox Discovery provides automated network device and serv
I’ve been building Rails applications for the last 10 years on a daily base and almost all of them use active storage now. Users are uploading files and then the questions start rolling in from the team and they are always the same: “How much storage are we actually using?” “Can we see which files aren’t attached to anything anymore?” “What types of files are users uploading the most?” “Is there a way to browse through all our stored files?” I usually open the Rails console, write a few querie
Last year marked the 70th anniversary of the first Godzilla, and Toho has spent much of that 70th year going all-in to celebrate the King of the Monsters.

Edgar Cervantes / Android Authority TL;DR T-Mobile has added two new privacy toggles: one for sharing certain financial information and another for fraud/identity theft protection. The first toggle allows T-Mobile to share your financial data with affiliates and marketers, while the second is meant to help detect fraud. You can disable both toggles in the T-Life app, and for most people, turning off the first is strongly recommended. T-Mobile and the other big carriers have a certain reputat

Bill Gates will not give up. The Microsoft co-founder turned philanthropist is continuing his public campaign against the Trump administration’s drastic cuts to U.S. foreign aid, warning of disastrous and preventable consequences for global health programs. His strategy is twofold: sound the alarm on the immediate human cost while highlighting the long-term benefits of American generosity. He just did both. Gates amplified a harrowing, firsthand account from a doctor in Africa whose clinic, fu

Reactive pots and pans made of aluminum, cast iron, hammered steel, brass, or copper can react with some chemicals in foods, especially the acids and salts in sauces, brines, and marinades, and they can undergo a chemical reaction and create off flavors, and in rare cases, are toxic.

Lonely children and teens are replacing real-life friendship with AI, and experts are worried. A new report from the nonprofit Internet Matters, which supports efforts to keep children safe online, found that children and teens are using programs like ChatGPT, Character.AI, and Snapchat's MyAI to simulate friendship more than ever before. Of the 1,000 children aged nine to 17 that Internet Matters surveyed for its "Me, Myself, and AI" report, some 67 percent said they use AI chatbots regularly

Of that, $122 million came from North America, making it the first superhero movie in the territory since 2024’s Deadpool & Wolverine to cross $100 million. Compared to other DC films, it’s the brand’s first movie to cross that milestone in North America since 2022’s The Batman ($134 million), and it

After analyzing dozens of teen films, communications researchers at the University of Ohio found, per a new study published in the Journal of Children and Media, that the experiences depicted in them was so different from the lives and experiences of actual teens that they may as well have been speculative fiction. Looking at 53 teen films
