Astronomers Just Found a Record-Breaking Space Explosion That Makes No Sense

If you’ve been following Gizmodo’s astrophysics coverage, you’ve probably noticed a pattern: Scientists study a cosmic phenomenon and start to get a handle on it—then something shows up that completely upends their understanding. The latest example? It’s explosive. Literally. Gamma-ray bursts (GRBs) are the most powerful explosions in the universe. Generally, GRBs last from milliseconds to several minutes. Scientists believe they emerge when massive stars explode in supernovas or get ripped apa

I never imagined a watch like the Garmin Forerunner 970 when I started running

Garmin Forerunner 970 The Garmin Forerunner 970 is everything you want in a running watch, and almost everything you'd need from a smartwatch. Yes, you'll pay like you're buying one of each, but it's a top-end wearable that you'll almost never have to take off your wrist, and it's light enough that you can go all day forgetting that you're even wearing it. My running journey started with a Garmin Forerunner. It wasn’t my watch — it was my high school cross country coach’s — but it brought a loa

Roborock Says a Robot Vacuum With an Arm Will Cost Just a Few Hundred Dollars

Roborock was the first company to market to offer a robot vacuum with a mechanical arm to help you sort items, with the Roborock Saros Z70 making a strong impression on us when we tested it. We liked its capabilities (despite some bugs) and it earned a spot on our list of best robot vacuums, with the caveat that the hefty $2,600 price tag put it out of reach for most people. In a recent interview with CNBC, Quan Gang, president of Roborock, suggested that robot vacuums with arms won’t stay this

D4d4

A co-worker of mine was looking at some disassembled ARM code the other day, and discovered something weird. Lots of d4d4 instructions, scattered about. LLVM’s objdump says this is a relative branch to -0x58 . The weird part is that they were always unreachable.

PNY’s Overclocked RTX 5070 Ti Is Finally Selling at Retail

If you've been hunting for a new GPU, you already know that getting one for its suggested retail price isn't guaranteed. High demand, low supply, and a constantly shifting economic space have caused the new 50 Series graphics cards to hit the market well above the expected price, at least at launch. Thankfully, the situation seems to be stabilizing a bit, as indicated by this deal on PNY's overclocked example of the GeForce RTX 5070 Ti, which is available on Amazon for its MSRP of $750. Even be

Google releases pint-size Gemma open AI model

Big tech has spent the last few years creating ever-larger AI models, leveraging rack after rack of expensive GPUs to provide generative AI as a cloud service. But tiny AI matters, too. Google has announced a tiny version of its Gemma open model designed to run on local devices. Google says the new Gemma 3 270M can be tuned in a snap and maintains robust performance despite its small footprint. Google released its first Gemma 3 open models earlier this year, featuring between 1 billion and 27 b

Ask HN: How can ChatGPT serve 700M users when I can't run one GPT-4 locally?

Sam said yesterday that chatgpt handles ~700M weekly users. Meanwhile, I can't even run a single GPT-4-class model locally without insane VRAM or painfully slow speeds. Sure, they have huge GPU clusters, but there must be more going on - model optimizations, sharding, custom hardware, clever load balancing, etc. What engineering tricks make this possible at such massive scale while keeping latency low? Curious to hear insights from people who've built large-scale ML systems.

Survival at High Altitudes: Wheel-Well Passengers (1996)

Abstract: Ten specific "wheel-well" passenger stowaway flights (the wheel-well area was entered just before takeoff) are documented in the N.Y. Times, covering the period 1947 to 1993. Five stowaways survived flights encompassing altitudes as high as 39,000 feet, with six dying in the process (one flight had two stowaways: one fatal, one surviving). Three Douglas DC-8 and four Boeing 707 aircraft, plus a Caravelle, an unknown jet, and a piston airliner were utilized. Several of the wheel well f

Battlefield 6 will cost $70 as EA avoids $80 game pricing &ndash; for now

A hot potato: It looks as if the consumer pushback against $80 becoming the new standard price for video games is having an effect. After Microsoft backtracked on plans to charge this amount for The Outer Worlds 2 and other new titles, EA has now said it won't be introducing the new baseline for AAA titles – at least "not at this stage." It means that the upcoming Battlefield 6 will be priced at the usual $70. Speaking during a Q1 earnings call (via IGN), EA CEO Andrew Wilson responded to an in

Netgear launches its most affordable Wi-Fi 7 mesh system

Netgear has launched its most affordable Wi‑Fi 7 mesh system yet, the Orbi 370. The headline price is $350 for a router and two satellites, which is extremely competitive. A quick look at the specs, however, reveals several trade‑offs that make the lower cost possible. The company says the Orbi 370 is “designed for customers with moderately demanding Wi‑Fi needs,” claiming the system’s total bandwidth is 5 Gbps. However, since it carries only a 2.5‑gigabit internet port, the maximum speed to a

What if AI made the world’s economic growth explode?

U NTIL 1700 the world economy did not really grow—it just stagnated. Over the previous 17 centuries global output had expanded by 0.1% a year on average, a rate at which it takes nearly a millennium for production to double. Then spinning jennies started whirring and steam engines began to puff. Global growth quintupled to 0.5% a year between 1700 and 1820. By the end of the 19th century it had reached 1.9%. In the 20th century it averaged 2.8%, a rate at which production doubles every 25 years.

Gig Speeds for Every American? Trump FCC Moves to Drop One of the Group’s Most Ambitious Goals

One of the federal government’s most ambitious broadband targets may soon be abandoned. On August 7, the FCC will vote on a proposal to drop its goal of gig speeds for every American. In March last year, the Democratic-led group voted to raise the definition of minimum broadband speeds from 25Mbps download and 3Mbps upload speed to 100/20Mbps. It also set a more ambitious long-term goal of increasing the benchmark to 1,000Mbps download and 500Mbps upload speed. Trump’s pick for FCC chair, Bren

Roborock Saros Z70 Review: OmniGrip Doesn’t Quite Work

I spent a few weeks lying in wait around my house, stalking it. My poor OmniGrip got into trouble all the time. I spent a morning wrestling the arm out of our freestanding toilet paper holder in the bathroom. It pulled all the kitchen towels off the rack. The emergency stop button (and the child lock) work, but you still have to pry the item out of its claw. Roborock has acknowledged in an email that there are many weird limitations to OmniGrip. For example, it does not recognize shoes that are
