Boy Genius Quits SpaceX for Greener Pastures

After making waves for getting a job at SpaceX's Starlink at the precocious age of 14, Bay Area boy wonder Kairan Quazi is preparing to leave the nest, move to New York, and get a new job. Quazi, now 16, explained to Business Insider why he's leaving Starlink to work for Citadel Securities, one of the world's biggest stock trading firms that specializes in the rapid-fire algorithmic transactions of quantitative finance. "After two years at SpaceX," the precocious teen told BI, "I felt ready to

Starlink wants billions in grants, but state governments aren’t cooperating

Starlink operator SpaceX isn't getting the broadband money it demanded from state governments despite the Trump administration rewriting the rules of a $42 billion grant program. Instead of directing the lion's share of money to Elon Musk's space and satellite company, early results indicate that states still plan to deploy fiber broadband networks to most of their unserved households. When the Trump administration announced its overhaul of the Broadband Equity, Access, and Deployment (BEAD) pr

Watch Stephen King and Takashi Miike Celebrate the Glorious Gore of ‘Texas Chain Saw Massacre’

“Every frame has something unnerving in it,” Patton Oswalt says in the trailer for Chain Reactions—a new documentary about the enduring influence and impact of 1974’s The Texas Chain Saw Massacre. Tobe Hooper’s grisly classic has often been imitated and has spawned some regrettable sequels and remakes, but the original remains a uniquely terrifying product of a very specific time and place, not just in pop culture, but also in the realms of independent cinema. A new trailer for Chain Reactions

Eye Exams: Tests Performed, Machines Used and What to Expect

Whether you deal with conditions like dry, itchy eyes, blurred vision or cataracts -- or enjoy perfect 20/20 vision -- regular eye exams are essential for protecting your sight and maintaining eye health. This is especially the case nowadays, when screen time and other lifestyle factors can significantly impact your eyes. To help you better understand exactly what happens during an eye exam, we contacted an optometrist to discuss the different tests and machines used and what an eye doctor eval

SpaceX has built the machine to build the machine. But what about the machine?

STARBASE, Texas—I first visited SpaceX's launch site in South Texas a decade ago. Driving down the pocked and barren two-lane road to its sandy terminus, I found only rolling dunes, a large mound of dirt, and a few satellite dishes that talked to Dragon spacecraft as they flew overhead. A few years later, in mid-2019, the company had moved some of that dirt and built a small launch pad. A handful of SpaceX engineers working there at the time shared some office space nearby in a tech hub buildin

Spirit Halloween Has Made the Most Affordable ‘Jurassic Park’ Goggles Replica We’ve Seen

The iconic T. rex escape scene is seared into the collective core memory of Jurassic Park fans. Steven Spielberg’s blockbuster franchise is full of memorable moments, from the jiggling water to the lawyer running to the bathroom. But if you, like me, had the film as one of your earliest and most life-changing cinema-going experiences, there’s not a detail forgotten—especially not the goggles. You know the ones that Tim grabs and the lawyer tells him to put back, because if they’re heavy, “they’r

Do Large Language Models Dream of AI Agents?

During sleep, the human brain sorts through different memories, consolidating important ones while discarding those that don’t matter. What if AI could do the same? Bilt, a company that offers local shopping and restaurant deals to renters, recently deployed several million agents with the hopes of doing just that. Bilt uses technology from a startup called Letta that allows agents to learn from previous conversations and share memories with one another. Using a process called “sleeptime compu

Improvements to OCaml code editing: the basics of a refactor engine

Refactoring features have contributed to the popularity of editors like IntelliJ, as well as certain programming languages whose editor support offers interactive mechanisms to manage code — Gleam being an excellent example. Even though OCaml has some features related to refactoring (such as renaming occurrences, substituting typed holes with expressions, and case analysis for pattern matching), the goal of my internship was to kickstart work on a robust set of features to enable the smooth inte

Dex is an AI-powered camera device that helps children learn new languages

Three parents—Reni Cao, Xiao Zhang, and Susan Rosenthal—were worried about their children’s screen time, so they left their tech jobs to create a product that encourages children to engage with the real world while also helping them learn a new language. Their move has paid off, as the company recently raised $4.8 million in funding. The newly launched gadget is called Dex and resembles a high-tech magnifying glass with a camera lens on one side and a touchscreen on the other. When kids use the

Intel Foundry Demonstrates First Arm-Based Chip on 18A Node

Images in this post: Intel, via TechPowerUp! Intel Foundry needs external customers, as the company claims that if it doesn't find more, it may have to "pause or discontinue our pursuit of Intel 14A and successor nodes." That could explain why the company posted a video today on its YouTube channel showing off "Deer Creek Falls", a new "reference SoC" fabricated on its 18A process.The video has since been removed, which is why we're crediting TechPowerUp on the screenshots, but it clearly sho

Ask HN: Why does the US Visa application website do a port-scan of my network?

I have recently installed this extension on FF: https://addons.mozilla.org/en-US/firefox/addon/port-authorit... and yesterday I visited this website: https://ceac.state.gov/genniv/ and I got a notification that the website tried to do a port-scan of my private network. Is this a common thing? I have just recently installed the extension, so I am not sure if there are a lot of other websites who do it. Since looking into it, I noticed that uBlock Origin already has the default list "Block Outsi

How to Think About GPUs

We love TPUs at Google, but GPUs are great too. This chapter takes a deep dive into the world of NVIDIA GPUs – how each chip works, how they’re networked together, and what that means for LLMs, especially compared to TPUs. This section builds on Chapter 2 and Chapter 5 , so you are encouraged to read them first. What Is a GPU? A modern ML GPU (e.g. H100, B200) is basically a bunch of compute cores that specialize in matrix multiplication (called Streaming Multiprocessors or SMs) connected to a

Tiny, removable "mini SSD" could eventually be a big deal for gaming handhelds

Earlier this year, Nintendo helped popularize the microSD Express standard by requiring it for the new Switch 2 console. Created in 2019, the specification had languished in relative obscurity for years because the cheap, plentiful non-Express microSD cards were generally fast enough for the things that people were using them for, and because most hardware didn't support microSD Express cards in the first place. However, Nintendo's console needed performance closer to that of an internal SSD to

CarPlay just arrived as a free OTA update for one of the fastest-growing EVs

CarPlay has just expanded to one of the fastest-growing EVs on the market, arriving this week through a free over-the-air update. Geely may not be a household name in the United States, but it’s a major global player with ownership ties to Volvo, Polestar, Lotus, and Smart. The company’s latest electric SUV, sold in China as the Galaxy E5 and internationally as the EX5, has surged in sales and ranks high among the most popular EVs. The EX5 launched in mid-2024 and reached its 100,000th unit i

Plex urges users to update Media Server after fixing a ‘potential security issue’

Plex, the popular app for organizing and streaming personal media collections, is warning users running certain Plex Media Server versions to update immediately due to a “potential security issue” that was recently patched. Here are the details. Urgent fix, no details As reported by BleepingComputer (via Tecnoblog), Plex is reaching out to users running server versions 1.41.7.x through 1.42.0.x, and urging them to update to Plex Media Server 1.42.1.10060 as soon as possible.

Unsealed Apple Pay ruling explains Fintiv’s Texas retreat and weakens new Georgia case

A newly unsealed opinion shows why Apple had little patience for Fintiv’s long-running claims in Texas. As it turns out, after seven years of litigation, Fintiv still could not point to any evidence that Apple Pay or Apple Wallet ever used the kind of “widget” described in its patent. That finding explains the company’s abrupt retreat in Texas and bodes poorly for its latest attempt to profit off Apple Pay in Georgia. Why Fintiv’s Texas claims collapsed Judge Alan Albright, who oversees one of

CRDT: Text Buffer

← Back to the algorithm list Published on May 19th, 2024 Collaboratively editing strings of text is a common desire in peer-to-peer applications. For example, a note-taking app might represent each document as a single collaboratively-edited string of text. The algorithm presented here is one way to do this. It comes from a family of algorithms called CRDTs, which I will not describe here. It's similar to the approaches taken by popular collaborative text editing libraries such as Yjs and Auto

Without the futex, it's futile

Phil Eaton’s book club is starting The Art of Multiprocessor Programming, 2nd Edition , which is a very well regarded textbook, and pretty recently updated (2021). I’ve even heard of a couple of authors. I’ve done a lot of concurrent programming, and have always felt like I’ve still got plenty to learn, so I was excited for the topic. So far, what I’ve learned is that I would never recommend this book, despite any merits. Academia certainly struggles to find the right balance between teaching

Appeals court says NLRB structure unconstitutional, in a win for SpaceX

A federal appeals court handed SpaceX a win on Tuesday, in a ruling that prevents the National Labor Relations Board from prosecuting unfair labor practices against the company. The ruling by the Fifth District Court of Appeals, which suggests the structure of the NLRB is likely unconstitutional, could have far-reaching effects. The ruling keeps unfair labor practice cases against SpaceX and two other companies, Energy Transfer and Findhelp, on hold while the companies pursue their claim that t

D2 (text to diagram tool) now supports ASCII renders

In the latest release of D2 (0.7.1), we introduce ASCII outputs. Any output file with extension txt will use the ASCII renderer to write to it. Here is an example of their rendering from the D2 Vim extension. The user opens a .d2 file and opens a preview window, which updates upon every save. Perhaps the most useful place for ASCII diagrams is in the source code comments. Small simple diagrams next to functions or classes can serve to be much clearer than describing a flow. Here again the Vi
