Make Your Own Backup System – Part 1: Strategy Before Scripts

Backup: Beyond the Simple Copy For as long as I can remember, backup is something that has been underestimated by far too many people. Between flawed techniques, "Schrödinger's backups" (i.e., never tested, thus both valid and invalid at the same time), and conceptual errors about what they are and how they work (RAID is not a backup!), too much data has been lost due to deficiencies in this area. Nowadays, backup is often an afterthought. Many rely entirely on "the cloud" without ever asking

Permit for xAI’s data center blatantly violates Clean Air Act, NAACP says

xAI continues to face backlash over its Memphis data center, as the NAACP joined groups today appealing the issuance of a recently granted permit that the groups say will allow xAI to introduce major new sources of pollutants without warning at any time. The battle over the gas turbines powering xAI's data center began last April when thermal imaging seemed to show that the firm was lying about dozens of seemingly operational turbines that could be a major source of smog-causing pollution.

European VC breaks taboo by investing in pure defense tech from Ukraine’s war zones

Defense tech has gone from a no-go zone for VCs to a hot investment sector. However, dual use — meaning that the technology must also have civilian applications — is still a requirement for most of them, including the NATO Innovation Fund. Estonian VC firm Darkstar breaks from this trend by investing in purely military applications, with the goal of helping rearm Europe using combat-proven solutions emerging from Ukraine. “This is very critical, not only today but for the next 10 years,” said i

Tyr, a new Rust DRM driver targeting CSF-based ARM Mali GPUs

The last year has seen substantial progress on the DRM infrastructure required to write GPU drivers in Rust. While a great part of it was fueled by the development of Nova (the new driver for GSP-based NVIDIA GPUs), and by AGX (the driver for the GPUs on Apple's M-series chip that preceded Nova), a few components were being worked on to cater to a then undisclosed driver that was being prototyped behind the scenes. A driver that we now introduce to the community at large in a very early stage.

AI is forcing the data industry to consolidate — but that’s not the whole story

The data industry is on the verge of a drastic transformation. The market is consolidating. And if the deal flow in the past two months is any indicator — with Databricks buying Neon for $1 billion and Salesforce snapping up cloud management firm Informatica for $8 billion — momentum is building for more. The acquired companies may range in size, age, and focus area within the data stack, but they all have one thing in common. These companies are being bought in hopes the acquired technology w

Got a suspicious UPS text? Don't reply - it might be a scam. Here's how to tell

Elyse Betters Picaro / ZDNET I've been anxiously expecting a package from UPS. That's why a text I received the other day caught my eye. Claiming to be from UPS, the message said that the carrier attempted to deliver the package on June 27, but the delivery couldn't be completed. The date was one when my wife and I were away, so this seemed legitimate at first glance. Also: Got a suspicious E-ZPass text? Don't click the link (and what to do if you already did) However, I've written plenty of

Some thoughts on my first YC Demo Day

This year was my first time attending YC Demo Day. It’s a fascinating event and, really a fascinating product for investors. Growing up in the bay area, I remember over a decade ago admiring people in YC. I was always impressed and it is a real privilege to be able to attend from the other side (as an investor). I went not because I am a prolific investor, I went because I thought that it would be a unique experience. The Product: Startups This seems obvious, but the startups are the produc

AI Startup That Raised $81 Million to Detect Wildfires Bamboozled by Clouds, Still Relies on Humans

It's boom time for AI startups. Across the world, enterprising tech types are being rewarded with millions for forcing AI into all kinds of gadgets, like an autonomous lawnmower, an AI-powered robo-mattress, and even an AI-enabled toilet. While the vast majority of even the most well-funded AI startups tend to collapse like houses of cards, VC spending on outlandish techno slop — like the Lemonflow, a "voice-based AI agent for charging infrastructure" — isn't slowing down. In the first three mo

US recovers $225 million of crypto stolen in investment scams

The U.S. Department of Justice has seized more than $225 million in cryptocurrency linked to investment fraud and money laundering operations, the largest crypto seizure in the history of the U.S. Secret Service. The state's investigators used blockchain analysis to trace the funds stolen from over 400 victims, which were then laundered through a complex network of cryptocurrency addresses to obscure their origin. "The complaint alleges that the cryptocurrency addresses that held the over $225

Modder runs AMD FSR 4 on unsupported Radeon 7000 series GPUs, performance lags behind FSR 3.1

Serving tech enthusiasts for over 25 years.TechSpot means tech analysis and advice you can trust In brief: AMD's new FSR 4 upscaling solution improves tremendously upon FSR 3 but only supports the company's Radeon RX 9070 and 9060 graphics card families. However, the latest version of Mesa for Linux provides a loophole that allowed a modder to benchmark FSR 4 on an older GPU, with intriguing results. Redditor Virtual-Cobbler-9930 recently shared encouraging data after testing AMD's FSR 4 on a

Stripe’s former growth lead helps African diaspora invest in startups, real estate

When Joe Kinvi joined Touchtech Payments in 2017 as head of finance, the Irish startup couldn’t afford his full salary. So he negotiated for stock to make up the difference. Eighteen months later, Stripe acquired the company, and that equity converted into Stripe shares, enough to let Kinvi leave his job, bootstrap a side project, and eventually found a startup. That startup, Borderless, is now helping Africans in the diaspora collectively invest in startups and real estate back home. Since lau

College Dropout Entrepreneur Boasts That Peter Thiel's Book Is "Probably the Best Book I've Read, and I've Only Read a Few Pages"

Ever since college dropouts Steve Jobs and Steve Wozniak began pedaling the romantic tale of founding Apple in Jobs' parents' Los Altos garage, college-age tech bros have longed to follow in their footsteps. But there's just one tiny thorn: the "founder's story" of late-night struggles and coffee-fueled breadboarding is mostly a capitalist fairy tale. Still, it's a mythos tech billionaire overlord Peter Thiel is all too eager to stoke. His empire is built on image — even the stereotypical "evil

macOS dropping support for AirPort/Time Capsule disk Time Machine backups next year

Apple disbanded its router hardware team in 2016 and officially exited the business in 2018. Now in 2025, Apple is signaling that one of the last remaining benefits of its networking hardware will be disabled next year. Spotted by @StellaFudge on X, macOS Tahoe 26 includes a warning message when using Time Machine to back up a Mac to Apple router-connected storage. The next major version of macOS will no longer support AirPort Disk, or other Time Capsule disks, for Time Machine backups. When

After 20 years, math couple solves major group theory problem

After the conjecture was posed in the 1970s, dozens of mathematicians tried their hand at proving it. They made partial progress — and in the process they learned a great deal about groups, which are abstract objects that describe the various symmetries of a mathematical system. But a full proof seemed out of reach. Then Späth came along. Now, 20 years after she first learned about the problem and more than a decade after she met Cabanes, the two mathematicians have finally completed the proof.

This company is trying to make a biodegradable alternative to spandex

“True circularity has to start with raw materials,” says Peña. “We talk about circularity across many industries, but for textiles, we must address what we’re using at the source.” Engineered from recombinant DNA, SELPs are copycat proteins inspired by silk and elastin that can be customized for qualities like tensile strength, dye affinity, and elasticity. Silk’s amino acid sequences—like glycine-alanine and glycine-serine—give fibers strength, while elastin’s molecular structure adds stretchi

Tesla Cybertruck: all the news about Elon Musk’s futuristic pickup truck

Here’s everything you need to know about Tesla’s first pickup truck, which Elon Musk has called “heart-stopping” and his “personal favorite” of Tesla’s vehicles. Pickups have become more popular lately — their share of the US light vehicle market increased to 17.5 percent in 2019, from just under 13 percent in 2012. They’re also the fastest-growing auto segment in the US. That makes Tesla’s entry into pickups sensible, analysts say. Another pickup perk: pricing. Pickups tend to be expensive. E
