Show HN: Reviving a 20 year old OS X App

In my recent foray into learning Dutch for my relocation to the Netherlands – I'm sure there'll be much to blog about – I fell victim to the siren song of the Green Owl again. It's too tempting - you get showered with instant feedback, encouragement in-app rewards, social stuff etc. To be fair it is fun, and you really feel that you're doing something useful. …except. I last used it in earnest it to 'learn' German before a trip to Berlin. I racked up a 150+ day streak or something nuts like t

Designing for the Eye: Optical corrections in architecture and typography

Designing for the Eye Optical Corrections in Architecture and Typography By Niko Kitsakis, June 2025 This article highlights a special aspect of both visual design and architecture: Optical cor­rections (or optical ad­just­ments, if you prefer). If you found my piece about legible typefaces interesting, you’ll likely enjoy this one as well.

After a Decade of Chaos, Google Is Finally Getting Its Act Together

For over a decade, Google has ruled the mobile world in market share but not in power. Android is the most widely used operating system on the planet, yet Apple still controls the conversation, the culture, and the profits. Google’s vast empire, stretching from Chrome to Android, Gemini to Pixel, and foldables to tablets, has never quite clicked together. It’s powerful but disconnected, popular but often forgettable. That is about to change. Or at least, that is the plan. In a recent TechRadar

Trump Lets Polymarket Off the Hook, Ends Probe Into Crypto Betting Platform

If you bet “Donald Trump ends an investigation into a Peter Thiel-backed cryptocurrency platform,” you can claim your winnings. According to Bloomberg, two investigations into the prediction market Polymarket have been shut down by the Trump administration, just in time for Republican lawmakers’ planned “Crypto Week.” The probes, which were launched toward the end of the Biden administration, included an investigation by the Department of Justice into whether Polymarket was allowing U.S.-based

Billionaires Convince Themselves AI Chatbots Are Close to Making New Scientific Discoveries

Generative artificial intelligence tools like ChatGPT, Gemini, and Grok have exploded in popularity as AI becomes mainstream. These tools don’t have the ability to make new scientific discoveries on their own, but billionaires are convinced that AI is on the cusp of doing just that. And the latest episode of the All-In podcast helps explain why these guys think AI is extremely close to revolutionizing scientific knowledge. Travis Kalanick, the founder of Uber who no longer works at the company,

Grok's AI chatbot now includes companions for you to 'romance'

Grok, xAi's chatbot most famous for going on an antisemitic spree last week, has now added the ability to perform as a synthetic companion for your enjoyment. Elon Musk announced the new feature, available to paid subscribers, which will take the form of animated characters Ani and Rudy. Both are distinctly not safe for work, with the former operating as a digital waifu for you to, uh, romance. Rudy, on the other hand, is a red panda with a smart mouth who likes to get rude with the people he's

Sony's 61MP RX1R III fixed-lens compact camera is finally here after a ten-year wait

Sony just surprised the photography world by unveiling the RX1R III, a fixed-lens 35mm full-frame compact camera. Coming nearly ten years after the RX1R II, it has a 61MP Exmor R sensor along with Sony's latest image processing technology that promises low noise and high dynamic range. Apart from all the new tech, the RX1R III is smaller and more streamlined than before and considerably lighter at 17 ounces than its main competition, Leica's Q3 and the Fujifilm GFX100RF. With that, it's designe

Musk Calls on Trump to Release Epstein Files

President Donald Trump's loyal MAGA base is in shambles over his administration's handling of files related to the deceased sex criminal Jeffrey Epstein — and Trump's friend-turned-enemy Elon Musk is twisting the knife. Last week, White House officials walked back claims about the late billionaire sex criminal, arguing that there wasn't a "client list" full of celebrities, and that his cause of death in a New York City prison cell was the result of a suicide, not murder. The terse announcement

Oh Great, the TikTok People Want to Strap AR Goggles on Your Face

There’s reportedly a potential new player in AR glasses, and you’ll never guess who it is. I’ll give you a hint: they make the app you’re about to unconsciously check in about 15 seconds. No, not Tinder; get your mind out of the gutter. I’m talking about TikTok, or more specifically, ByteDance, which owns TikTok and also, according to The Information, which cites sources within the company, has aspirations of entering the burgeoning world of XR hardware. ByteDance’s entrant, according to the rep

Interview With Mark Zuckerberg Crashes and Burns as They Can't Get His Audio Working

Tech-focused business publication The Information drummed up plenty of excitement around a major guest gracing the first episode of its new YouTube show (which has the eyebrow-raising name TITV.) During today's kickoff installment, the show locked down none other than Meta CEO Mark Zuckerberg, who sat down with The Information founder and journalist Jessica Lessin for a live interview. But it didn't take long for the Amazon-sponsored chat to grind to a halt. The tech mogul and Lessin's audio w

Superheroes Are Spending 2025 in Their Reboot Eras

There have been a lot of superhero stories told over the decades from DC and Marvel, but it’s been a while since things lined up quite like this. Of 2025’s wave of cape movies and shows, several of them—from Thunderbolts* and Your Friendly Neighborhood Spider-Man to the just-released Superman and incoming Fantastic Four: First Steps—are reboots in some form or another. In the comics these characters originated from, reboots happen on a regular basis, and their movie counterparts are no strangers

Lightning Detector Circuits

Here's a version I built into a "fake" book I found at an art store. The copper PCB is connected to the circuit ground to act as a counterpoise for the antenna, increasing sensitivity. The lightning bolt was cut with a sharp knife then filled with blue-dyed epoxy. The antenna connects to the pin jack. I used a cheap flashlight head for the LED - I used too much blue dye in the epoxy so I need a bright flash! The image below is with an LED and no pot (but with the 150k resistor added). I made se

How AI can make us better decision-makers, with Cassie Kozyrkov

Hello, and welcome to Decoder! This is Jon Fortt, CNBC journalist, cohost of Closing Bell Overtime, and creator and host of the Fortt Knox podcast. As you just heard Nilay say, I’m stepping in to guest host a few episodes of Decoder this summer while he’s out on parental leave, and I’m very excited about what we’ve been working on. For my first episode of Decoder, a show about how people make decisions, I wanted to talk to an expert. So I sat down with Cassie Kozyrkov, the founder and CEO of AI

Rivian R1S review: second time’s the charm

Just four years after Rivian began selling its R1T truck, 2025 marks the beginning of the R1T and R1S’ second generation. Considering they look essentially the same on the outside, it might be hard to decipher what warrants a new generation. But underneath, it’s actually quite easy: all-new electric architecture, a new motor arrangement, retuned suspension, and more. Kicking off at $107,700, here’s how all these revisions make the 2025 Rivian R1S Premium Tri-Motor a true frontrunner in the moder

Repasting a MacBook

You should repaste your MacBook (but don't) My favorite memory of my M1 Pro MacBook Pro was the whole sensation of “holy crap, you never hear the fans in this thing”, which was very novel in 2021. Four years later, this MacBook Pro is still a delight. It’s the longest I’ve ever owned a laptop, and while I’d love to pick up the new M4 goodness, this dang thing still seems to just shrug at basically anything I throw at it. Video editing, code compiling, CAD models, the works. (My desire to updat

Measuring power network frequency using junk you have in your closet

Over the weekend starting on Saturday, the 8th of February 2025, the Baltic states’ electricity grid is switching from being synchronized with the Russian electric grid to being synchronized with the continental European electrical grid. This involves first disconnecting from the Russian grid, then operating a while as an island system, regulating the frequency alone and doing various tests, and finally, synchronizing frequency and phase with the EU grid and throwing the breaker. Which made me w

Some Verge-favorite gadgets are still on sale as Prime Day winds down

Samsung's New Phones Show How Far Ahead China Is on Innovation

Earlier this week, Samsung announced the latest generation of its high-end foldable phones at its Summer Galaxy Unpacked event. The Galaxy Z Fold7 and the Galaxy Z Flip7 are variously lighter, thinner, less crease-prone than before. They are more expensive too. Some call them the “foldables to beat.” It’s Samsung messaging and a commentator response that sounds an awful lot like what we heard last year. And the year before that, for that matter, in a hall of echoes typical of the iterative prog

Will That Massive ‘Superman’ Revelation Impact the Future of DC?

James Gunn’s Superman centers on a few key moments. One of the biggest is the message Kal-El, played by David Corenswet, was left with from his Kryptonian parents. If you’ve seen the movie, you know how it plays out. (And, if you haven’t, it’s a pretty big spoiler, so proceed with caution.) Either way, it’s a bombshell revelation that changes not just the character but the entire trajectory of the movie, and so we had to talk to the people most directly affected by it. Recently io9 sat down wit

Meta’s Obsession With AI Will Make Smart Glasses Finally Click

Meta made some pretty major moves in AI this week, and some of them were supremely expensive. According to Bloomberg, Meta spent a whopping $200 million trying to poach just one person from Apple (Ruoming Pang, the former lead in charge of developing the large language models behind Apple Intelligence), and that’s just one person it scooped up in its flurry of AI talent acquisitions—there are several others from OpenAI that also jumped ship just this week. It’s to be expected in one way. AI is
