The TTY Demystified (2008)

The TTY subsystem is central to the design of Linux, and UNIX in general. Unfortunately, its importance is often overlooked, and it is difficult to find good introductory articles about it. I believe that a basic understanding of TTYs in Linux is essential for the developer and the advanced user. Beware, though: What you are about to see is not particularly elegant. In fact, the TTY subsystem — while quite functional from a user's point of view — is a twisty little mess of special cases. To und

DSLRoot, Proxies, and the Threat of 'Legal Botnets'

The cybersecurity community on Reddit responded in disbelief this month when a self-described Air National Guard member with top secret security clearance began questioning the arrangement they’d made with company called DSLRoot, which was paying $250 a month to plug a pair of laptops into the Redditor’s high-speed Internet connection in the United States. This post examines the history and provenance of DSLRoot, one of the oldest “residential proxy” networks with origins in Russia and Eastern E

One Universal Antiviral to Rule Them All?

For a few dozen people in the world, the downside of living with a rare immune condition comes with a surprising superpower—the ability to fight off all viruses. Columbia immunologist Dusan Bogunovic discovered the individuals’ antiviral powers about 15 years ago, soon after he identified the genetic mutation that causes the condition. At first, the condition only seemed to increase vulnerability to some bacterial infections. But as more patients were identified, its unexpected antiviral benef

Exclusive: I put a leaked iPhone 17 Pro Max case on an iPhone 16 Pro Max

TL;DR Android Authority obtained a leaked iPhone 17 Pro Max case from a company called Thinborne. obtained a leaked iPhone 17 Pro Max case from a company called Thinborne. The case fits very well on the iPhone 16 Pro Max, showing that the sizing is nearly identical. However, Apple appears to be moving the LiDAR sensor, microphone, and flash, so iPhone 16/17 cases will likely not be interchangeable. Now that the Google Pixel 10 launch is over, it’s time to look to the next huge smartphone laun

Hands-on: Kuxiu debuts tiny smart connector charger for iPad: meet the M30 [Updated]

Kuxiu continues to make some of the best iPad accessories in the game. They were the first to introduce “wireless” charging for the iPad by implementing the smart connector into their products, like the X33 Pro Max. It was the first magnetic iPad stand that also charged your iPad Pro with those smart connectors. They have doubled down on that and made it ultra compact. Today, they unveiled the M30 Magnetic Smart Connector Charger, and I’m so excited about it. Here is what you should know. Hands

Rumor: AirPods Pro 3 design will borrow two changes from AirPods 4

Earlier this week, Bloomberg offered great news for the AirPods Pro 3 launch timing, and now a new rumor indicates Apple has design changes coming that take inspiration from AirPods 4. AirPods Pro 3’s charging case is shrinking and removing pairing button, hinting at larger redesign We are likely just a couple weeks away from AirPods Pro 3 being unveiled. And despite an absence of leaks around product details for the last few months, rumors have started flowing again. Today’s new rumor involv

Google Pixel 10 Pro XL vs. Samsung Galaxy S25 Ultra: I tested both Androids, and it's pretty darn close

The Google Pixel 10 Pro XL (left) next to the Samsung Galaxy S25 Ultra (right). Kerry Wan/ZDNET Follow ZDNET: Add us as a preferred source on Google. The Google Pixel 10 Pro XL is one of the hottest new Android phones right now, but how does it stack up to the current champ? Ahead of last week's Made by Google event, I spent an intimate morning handling both the new Pixel model and the Samsung Galaxy S25 Ultra to determine which one deserves a spot in your pocket. The answer is... complicated.

'Ten Martini' Proof Uses Number Theory to Explain Quantum Fractals

But in some ways, the proof was a bit unsatisfying. Jitomirskaya and Avila had used a method that only applied to certain irrational values of alpha. By combining it with an intermediate proof that came before it, they could say the problem was solved. But this combined proof wasn’t elegant. It was a patchwork quilt, each square stitched out of distinct arguments. Moreover, the proofs only settled the conjecture as it was originally stated, which involved making simplifying assumptions about th

Tech’s Heavy Hitters Are Spending Big to Ensure a Pro-AI Congress

Much of the American public is dubious to neutral when it comes to artificial intelligence. A recent poll found that 71 percent of Americans were concerned about the technology “permanently” displacing human workers. Since we ostensibly live in a democracy, you’d think that would be bad news for the AI industry; unfortunately, many of the folks who are central to our economy are all-in. What do you do when you can’t win in the court of public opinion? The next best thing is to work the refs, a

The Pixel 10 Pro is the wrong Pixel to buy this year

The dust has settled from the latest Made by Google event, and the Pixel 10 family is as good as ever. It builds on the hardware upgrades that Google introduced on the Pixel 9 series and packs more new AI-powered features than I could have dreamt when I first put my SIM in a Pixel device. And I, for one, cannot wait to move my SIM into yet another brand-new phone by Google — but not the one you might expect. There are reasons to go Pro… but not quite as many C.

It’s time for Google to address this major Play Store issue

Karandeep Singh / Android Authority Google’s Play Store has a serious problem, and it’s something that’s a big source of frustration for me. While many apps on the Play Store offer subscriptions, I find it nearly impossible to figure out the exact price before I download them. Google makes it clear that an app offers “in-app purchases” right on the main page, but it never gives me the crucial pricing information I need. This might seem like a small issue, but for me, it matters a lot. Price is

Prepare your wallets: Here’s when Samsung’s Android XR headset could be launching

Lanh Nguyen / Android Authority TL;DR Samsung’s long-awaited Project Moohan XR headset is reportedly launching on September 29 at the next Galaxy Unpacked event. The headset, possibly rebranded as the “Galaxy XR,” is powered by a Snapdragon XR2 Gen 2 SoC and 16 GB of RAM. Its rumored price is between $1,800 and $2,000, making it cheaper than the Apple Vision Pro. Samsung teamed up with Google for its Project Moohan headset on the brand-new Android XR platform. At the beginning of this year,

The Jonas Brothers music video isn’t the camera flex Google hoped for

I don’t mind the Jonas Brothers. I grew up when they starred in movies like Camp Rock and watched them make a few appearances at Penn State over the four years I was there. Honestly, their music is decent — even if I don’t make the biggest effort to seek it out. So, I was happy to go into the debut of their “I Can’t Lose” music video with an open mind, mainly since it was shot on the Pixel 10 Pro that I’m so eager to review. But now that I’ve replayed it a few times, I’m not sure the partnershi

The phone is tipped to start at $649.99 for the 128GB model, while the 256GB variant is listed at $709.99 This would be in line with the Galaxy S24 FE’s US price.

Hi, My daily workhorse is a M1 Pro that I purchased on release date, It has been one of the best tech purchases I have made, even now it really deals with anything I throw at it.

Exploring the tragedy of the Counter-Strike 2 server browser

For those who enjoy Counter-Strike community servers, the situation in Counter-Strike 2 is rather dire. An avalanche of spam has rendered the server browser unusable. The transition from Global Offensive killed multiple small communities. And large server providers have taken advantage of these problems to monopolise the market. Trying to find a server either involves capitulating to these big vendors, or trawling through a trench of spam. Scraping the server browser allows us to have some in

Blacksky grew to millions of users without spending a dollar

If you haven’t been watching closely, you could be forgiven for assuming that Bluesky is a just liberal Twitter clone, or a newfangled imitator of Mastodon. But under the surface, something fascinating has been happening: this is the first time ever that a public benefit corporation with a small team has quickly scaled an open source social network, built on top of decentralized infrastructure, to tens of millions of users.

Overwatch 2 will overhaul its progression systems to show more visual flair in matches

The next season of Overwatch 2 will bring more than the usual new hero and battle pass to the team shooter. Blizzard announced that Season 18 will introduce a new take on the progression system.

Turning a Decommissioned iPhone into a UniFi Protect Camera

Turning a Decommissioned iPhone into a UniFi Protect Camera Friday, 15 August 2025 I’ve recently become a Ubiquiti UniFi disciple, including replacing our builder-basic doorbell from 1998 with Ubituiti G4 Doorbell Pro. This has brought me into the UniFi Protect ecosystem.

It occurred to me that I have a small collection of minicomput

Apple’s fall product lineup could have one glaring omission this year

Apple is on the cusp of its major launch season, with new hardware coming in nearly every product category. But rumors indicate there will be one glaring omission from these fall launches: the Mac.
