Ptar: Replacing .tgz for petabyte-scale S3 archives

Hi, I’m Julien, co-founder of Plakar. Before we built this, I spent years as an engineer and later as a manager of infra teams. We handled backups, compliance, and recovery. In every place, startups, big companies, regulated sectors, I saw the same routine: tar -czf archive.tgz /some/folder We all love that command. But in 2025, it can cause trouble. What’s changed since .tgz was invented Back when tar came out in 1979 or even gzip came out in 1994, things were simple: Data was small, jus

RapidRAW: A non-destructive and GPU-accelerated RAW image editor

RapidRAW A beautiful, non-destructive, and GPU-accelerated RAW image editor built with performance in mind. RapidRAW is a modern, high-performance alternative to Adobe Lightroom. It delivers a feature-rich, beautiful editing experience in a lightweight package (under 30MB) for Windows, macOS, and Linux. I developed this project as a personal challenge at the age of 18. My goal was to create a high-performance tool for my own photography workflow while deepening my understanding of both React

SVGs that feel like GIFs

The moving image below is only 49Kb and has an incredibly high resolution. It's similar to a GIF but instead of showing moving images, it shows moving SVGs! The best part: Github supports these in their README.md files! Getting these to work involves asciinema and svg-term-cli. After uploading the asciinema you can use the tool to download a file that you can immediately click and drag into a README. It's something that I'm using extensively on bespoken. How it works?

Rivian spinoff Also raises another $200M to build e-bikes and more

In Brief Also Inc., the micromobility startup spun out of Rivian earlier this year, has raised $200 million from Greenoaks Capital, according to a new report from Bloomberg News. The funding round brings Also’s post-money valuation to $1 billion. The startup raised $105 million from Eclipse Ventures earlier this year when it was cleaved from Rivian. Also started as a skunkworks team inside Rivian in 2022 known as Project Inder, as TechCrunch previously reported. The team started working on an

Product of Additive Inverses

Product of Additive Inverses By Susam Pal on 29 May 2025 A negative number multiplied by another negative number results in a positive number. Most of us learnt this rule during our primary or secondary school years. 'Negative times negative equals positive' was a phrase drummed into us during mathematics lessons. In this article, we will prove this rule, not just for numbers but for any algebraic structure that, in a general sense, behaves somewhat like numbers. Contents Illustration Let u

The Phantom of the Opera Has a Lot of Demands for His Immersive Masquerade

Elon Musk lashes out at Tesla bull Dan Ives over board proposals: 'Shut up'

Elon Musk, chief executive officer of SpaceX and Tesla, attends the Viva Technology conference at the Porte de Versailles exhibition center in Paris, June 16, 2023. Tesla CEO Elon Musk told Wedbush Securities' Dan Ives to "Shut up" on Tuesday after the analyst offered three recommendations to the electric vehicle company's board in a post on X. Ives has been one of the most bullish Tesla observers on Wall Street. With a $500 price target on the stock, he has the highest projection of any analy

The tech behind Rivian’s 2026 Quad Motor truck and SUV — and that kick turn

As Rivian starts accepting orders for its 2026 Quad Motor pickup truck and SUV, customers may initially be enticed by the power and tricks the four motors in these rebooted EVs can unleash. After all, four motors delivering a combined 1,025 horsepower and 1,198 pound-feet of torque — and the ability to accelerate from a standstill to 60 miles per hour in less than 2.5 seconds — is hard to ignore. But they should also pay attention to the software. “The Quad is really the pinnacle of everythin

Rivian unveils a new quad-motor R1 variant

Rivian has a new high-performance EV that you almost certainly don't need. On Tuesday, the automaker unveiled a quad-motor variant of the second-generation R1. The EV can do remarkable things, but it's positioned as more of an off-road brand magnet than a sensible purchase. The Gen 2 Quad R1T (truck) starts at $115,990, and its R1S (SUV) counterpart starts at $121,990. The Gen 2 Quad lineup packs serious power. The four motors combine to give it 1,025 horsepower and 1,198 lb-ft of torque. It ca

Activision took down Call of Duty game after PC players hacked, says source

Games giant Activision took down “Call of Duty: WWII” due to hackers exploiting a flaw in a specific PC version of the game, which led to several players getting their computers hacked, TechCrunch has learned. Last week, Activision announced that it brought offline the Microsoft Store version of “Call of Duty: WWII,” a 2017 first-person shooter, as the company was investigating “reports of an issue,” without specifying what the issue was. The company had just launched that version of the game,

New Research Bolsters Freaky Theory That Earth Sits in a Giant Cosmic Void

Images of the cosmos, such as the James Webb Space Telescope’s deep space snapshot, make space look chock-full of stuff. In the grand scheme of things, it is, but all those stars, galaxies, planets, and other celestial objects may not be as uniformly distributed as photos make them look. The fact is, space is likely peppered with bubbles of relative emptiness, and some astronomers believe we’re sitting inside of one. A growing body of evidence suggests that our entire Milky Way galaxy is locate

Parvati Shallow Says RIP to the ‘Black Widow’ and All That

Parvati Shallow, the reality TV maven and one-time Survivor winner, can now also add published author to her list of achievements. The legendary schemer, who orchestrated scores of blindsides on the beaches of the Cook Islands, Micronesia, and Fiji, has published a new memoir from Penguin Random House titled Nice Girls Don’t Win: How I Burned It All Down to Claim My Power. The book, a deeply revealing, personal excavation of Shallow’s childhood, divorce, relationships, and experience with reali

Seagate Compact 1TB Portable SSD Hits an All-Time Low, 260K+ Reviewers Might Envy This Prime Day Price

Tiny portable thumb drives are a great way to move important files, but they usually have one or both of two unfortunate shortcomings — they’re either fragile, small in capacity, or both. Not surprisingly, a USB-C thumb drive that conquers both of those issues comes from Seagate — the remarkable Ultra Compact 1TB portable SSD, which is just $80 right now in Amazon Prime Day Deal list. The Seagate Ultra Compact packs a full terabyte of storage into a tiny 2.78-inch body, and it’s also IP54 dust

Cybersecurity’s Unsung Heroes: Elevating Neurodiverse Talent in the Digital Age

They aren’t your average hires. They don’t glide through job interviews or thrive in open-plan offices. But when it comes to pattern recognition, threat modeling, or zero-day hunting, neurodiverse individuals often outperform their peers. And yet, they remain largely untapped in the cybersecurity workforce. If we’re serious about fortifying digital defense systems, it’s time we stop overlooking the neurodiverse minds that already think in ways most cybersecurity frameworks are only beginning to

Wayve CEO Alex Kendall brings the future of autonomous AI to TechCrunch Disrupt 2025

TechCrunch Disrupt 2025 hits Moscone West in San Francisco from October 27–29, bringing together more than 10,000 startup and VC leaders for a deep dive into the future of technology. One of the most compelling conversations on one of the AI Stages will feature a panel of innovators redefining what intelligent systems can do — and among them is Alex Kendall, co-founder and CEO of Wayve. From research breakthrough to real-world autonomy Kendall founded Wayve in 2017 with a bold vision: to unloc

Rivian’s new Quad-Motor R1T and R1S beat the competition in any conditions

Rivian provided flights from Albany, New York, to Reno, Nevada, and accommodation so Ars could drive the quad-motor R1s. Ars does not accept paid editorial content. It's getting harder to find hyperboles to describe the performance of modern EVs. Horsepower figures measured in four digits and acceleration figures clocking in well under three seconds aren't exactly de rigueur, but they're well short of rare these days. Rivian's latest generation ticks those boxes, joining the automaker's range

macOS Tahoe 26 beta 3 makes tabs less confusing

One of the most common complaints in macOS Tahoe 26 betas 1 and 2 was the new tab UI in apps like Safari and Terminal, which added a black bar to the bottom of inactive tabs. In beta 3, Apple seems to have reversed course. Whether it was intentional or a bug on Apple’s part, many users had trouble quickly identifying the active tab. The low contrast between the selected tab and the rest of the UI, combined with that black underline on the non-active tabs, led to confusion, with some thinking th

20TB WD External Hard Drive Costs Only $0.01 per GB—Amazon Crushes the Price for Prime Day

Prime Day is not only the best time to scoop up deals on the new MacBook or Dyson vacuum. It’s also a good opportunity to get your hands on some essentials like an external hard drive. WD, or Western Digital, is an iconic and trusted brand in the world of storage, and right now, their 20TB external hard drive is available at a price that’s hard to believe: just $269. That’s barely more than $0.01 per gigabyte, which makes it one of the most cost-effective storage solutions you’ll find anywhere.

Seagate Portable 2TB External Hard Drive Pops Up in Prime Day Deal, Costs Peanuts Compared to Old Prices

Digital clutter is one of those things that sneaks up on you. One minute, your computer has plenty of space. The next, you’re frantically struggling to figure out what you need to delete so you can save your latest file or photo. And it doesn’t have to be that way. Here’s the good news. You can just get an external hard drive to hold everything if you prefer, and it doesn’t have to cost you an arm and a leg to do that. It’s actually not that expensive either, especially with Prime Day going on.

KEF Xio Review: So Good, So Expensive

There’s a level of confidence you have to admire in a brand entering a new market and out-pricing almost every single one of its competitors, straight from the off. That certainly appears to be KEF’s strategy with its very first soundbar, the KEF Xio—an all-in-one Atmos soundbar that will set you back a cool $2,500 (£2,000.) Of course, there’s the obvious: that’s enough to buy yourself a pretty decent surround sound package, with a performance that any soundbar will struggle to match. But if yo

macOS Tahoe: Reports of FireWire’s death not greatly exaggerated

How dead is FireWire support in macOS Tahoe 26? As dead as the iPod, as far as the Mac is concerned, which is at least a little sad. Stephen Hackett checked. In classic 512 Pixels fashion, he’s conjured together a real world demonstration using a battle-tested FireWire 800 cable-connected drive, two Thunderbolt adapters including a Thunderbolt 2 to 3 dongle, and a Mac. Woof. The result? A drive that correctly appeared as several volumes on macOS Sequoia just looks like an adapter to nowhere on

LookingGlass: Generative Anamorphoses via Laplacian Pyramid Warping

Anamorphosis refers to a category of images that are intentionally distorted, making them unrecognizable when viewed directly. Their true form only reveals itself when seen from a specific viewpoint, which can be through some catadioptric device like a mirror or a lens. While the construction of these mathematical devices can be traced back to as early as the 17th century, they are only interpretable when viewed from a specific vantage point and tend to lose meaning when seen normally. In this p

ASUS 14″ Laptop (8GB RAM, 128GB SSD) Nearly 50% Off for Best Buy’s Black Friday in July, Prime Day Isn’t Alone

The smartphone spent the last decade and a half slowly taking over the world to the point now where it is now the primary way most folks “go online,” whether that’s checking their email, staying up to date with their friends through social media, or accessing the internet for all sorts of various needs. I even know some folks who opt to not own a computer at all because they can get it all done with their phone. Though, there are still some tasks that are just way less of a hassle when using a l

Drive Capital’s second act — how the Columbus venture firm found success after a split

The venture capital world has always had a hot-and-cold relationship with the Midwest. Investors rush in during boom times, then retreat to the coasts when markets turn sour. For Columbus, Ohio-based Drive Capital, this cycle of attention and disinterest played out against the backdrop of its own internal upheaval several years ago — a co-founder split that could have ended the firm but may have ultimately strengthened it. At a minimum, Drive achieved something newsworthy in today’s venture lan
