Two and a Half Years in GameDev

About 3 years ago, I joined a GameDev company, without any prior experience making games or hands-on exposure to this industry. Statistically, this time is not even enough’s to release a single game. But during that window, I was lucky to meet many talented people deeply involved in modern GameDev, who shared with me their career journeys, war tales, and anecdotes, and helped me shape my vision. One unexpected outcome of this switch was that many friends and former colleagues reached out to me

GameStop Might've Sold Your Purchase Data to Facebook: How to Claim a Piece of the Settlement

There's still time to claim part of GameStop privacy settlement. Have you bought something from video game retailer GameStop in the past five years? Did you have a Facebook account when you did so? According to an email I received awhile back, that includes me. If it includes you as well, you can claim your own piece of a brewing settlement from the company, and you've still got a few weeks to do so. Last month, GameStop agreed to pay $4.5 million to settle a class action lawsuit accusing it o

12 Best Kids Headphones (2025), Hearing Protection and More

Protect Those Headphones Satechi 2-in-1 Headphone Stand Photograph: Julian Chokkattu Even durable headphones are easy to damage. We have lost pairs to folks standing on them, cats and robot vacuums attacking the cables, and chairs rolling over them. I have learned that a stand or holder is worth the investment if it keeps those cans off the floor. Even if your kids only sometimes remember to use it, that could extend the likely lifespan of their headphones. We use the Satechi 2-in-1 Headphone

Development of a transputer ISA board

Development of a transputer ISA board I developed software for transputers in the years 1993-1996. A few months ago, I wrote some articles about my experiences, and most recently I developed a transputer emulator in Javascript After my transputer emulator in Javascript was working, I got curious about running my software on a PC computer. I have several PC motherboards with ISA connectors, and I decided to build a card compatible with the Inmos B004 (a single board to test transputer processor

Nothing's untestable

Vidhi Katkoria Technical Writer Nothing's untestable As the co-founder of HashiCorp, Mitchell has been instrumental in the development of tools that many of us use daily, like Vagrant, Terraform, Vault, and more. He also helped shape the initial testing strategies for them, gaining hard-won insights into testing complex software along the way. At BugBash, where everyone is a testing nerd (or at least wants to be), most of us have come across that one piece of code that cannot be tested. What d

Take Two: Eshell

30 Jun 2025 Charles Choi This is a contribution to the Emacs Carnival 2025-06: Take Two collection of posts on Christian Tietze’s blog. My first take with Eshell many years back did not leave a good impression. My early expectations was that it should act like any other shell, only to be unpleasantly surprised by it. It took a long time for me to warm up to Eshell. Upon reflection, it was because I wasn’t ready for it. Now Eshell is an inseparable part of my Emacs experience. Paradoxically th

Overthinking GIS (2024)

Overthinking GIS A roundabout way to downsampling data Maps in the Modern Era GIS is probably one of the best things to happen to cartography in the last couple hundred years. I say that with absolutely no knowledge of the history of map making, but GIS is wildly useful and consistent in how it is presented on publicly-accessible sites. I can go to the USGS National Map Viewer and am presented with more data and information than I could possibly ever find useful. Even more surprising is that

How the Binding of Two Brain Molecules Creates Memories That Last a Lifetime

The original version of this story appeared in Quanta Magazine. When Todd Sacktor was about to turn 3, his 4-year-old sister died of leukemia. “An empty bedroom next to mine. A swing set with two seats instead of one,” he said, recalling the lingering traces of her presence in the house. “There was this missing person—never spoken of—for which I had only one memory.” That memory, faint but enduring, was set in the downstairs den of their home. A young Sacktor asked his sister to read him a book

Ask not for whom the Louvre of Bluesky tolls, it tolls for thee

It’s a sad weekend over at Bluesky, where one of the best accounts has disappeared — although we can still hope for its resurrection. Known as The Louvre of Bluesky, the account in question struck fear into the hearts of bad posters everywhere. While it posted commentary and jokes of its own, its most brutally funny and haunting work came in the form of screenshots capturing rogue Bluesky posts in all their unhinged glory. It’s hard to write a proper appreciation now that the Louvre has vanish

Chasing Hobbies over Achievement Boosts Happiness (2023)

Summary: Individuals emphasizing freedom and hobbies experienced a boost in well-being, whereas those prioritizing achievement felt less happy. The research showed that valuing ‘hedonism’ and ‘self-direction’ led to increased happiness across India, Turkey, and the UK. In contrast, ‘achievement’ and ‘conformity’ values showed no direct happiness benefits. The findings spotlight the importance of balancing life pursuits for mental health. Key Facts: Prioritizing freedom led to a 13% increase

OpenAI CEO Sam Altman says he's 'politically homeless' in July 4 post bashing Democrats

OpenAI CEO Sam Altman posted on X Friday, saying he finds himself "politically homeless" as the Democratic party is no longer aligned with encouraging a "culture of innovation and entrepreneurship." Altman, whose company is a leader in artificial intelligence, made the post in celebration of the Fourth of July, saying he is "extremely proud to be an American" and believes the U.S. "is the greatest country ever on Earth." He used the post to share some of his political ideology, saying he belie

Tesla Robotaxi Rider Gets Bizarre Call Saying She Has to Exit Vehicle Immediately

YouTuber and Elon Musk stan Ellie Sheriff had a bizarre experience during her first Tesla robotaxi ride in Austin, Texas. As seen in a video she shared on her channel, "Ellie in Space," over the weekend, Sheriff got a strange call from the EV maker mid-ride, asking her and her fellow passenger to literally leave the vehicle due to incoming weather. "So we had to get out of the robotaxi, because weather is coming in," Sheriff said in the video while standing in the middle of a windy field. The

As a Wear OS fan, I’m embarrassed to admit how excited I am for this watchOS 26 feature

Kaitlyn Cimino / Android Authority I rely on lists to keep my life running: grocery lists, packing lists, home improvement checklists, birthday gift ideas for my 19 nieces and nephews, and ongoing logs of thank-you notes for gifts for my own kid. My note-keeping apps aren’t just productivity tools; they’re the backbone of my sanity. So, when Apple announced that the Notes app is coming to Apple smartwatches via watchOS 26, my ears perked up. Do you use note-taking apps on your smartwatch? 171

A Tesla robotaxi inexplicably drove into a parked car

One of Tesla's fully autonomous robotaxis grazed a parked car after completing a ride recently in Austin, Texas. In a video recorded by YouTuber DirtyTesla, a self-driving Model Y is seen turning and accelerating into a Toyota, making light contact with its tire. As seen in the video, the Model Y already dropped off its passenger, but had trouble navigating out of the dark alleyway afterwards. Tesla's robotaxi service launched in Austin just two weeks ago with a small fleet. According to DirtyT

Parametric shape optimization with differentiable FEM simulation

All examples are expected to run from the examples/<example_name> directory of the Tesseract-JAX repository . In this example, you will learn how to: Compose both Tesseracts with Tesseract-JAX to create a pipeline that can be used for differentiable shape optimization. Build a Tesseract that uses finite differences under the hood to enable differentiability of a non-autodifferentiable geometry operation (computing a signed distance field from a 3D model). In this notebook, we explore the opt

Inside a Utah desert facility preparing humans for life on Mars

Hidden among the majestic canyons of the Utah desert, about 7 miles from the nearest town, is a small research facility meant to prepare humans for life on Mars. The Mars Society, a nonprofit organization that runs the Mars Desert Research Station, or MDRS, invited CNBC to shadow one of its analog crews on a recent mission. "MDRS is the best analog astronaut environment," said Urban Koi, who served as health and safety officer for Crew 315. "The terrain is extremely similar to the Mars terrain

Wildly Beautiful and Rare "Red Sprite" Flare Seen on Earth From Orbit

Red Sprite NASA astronaut Nichole Ayers, currently stationed on board the International Space Station, shared an incredible image of a sprite — a rare weather phenomenon that's triggered high above the clouds by "intense electrical activity in the thunderstorms below." The image shows the rare electrical discharge in the shape of a starkly red, upended umbrella, hovering high over a brewing storm, like some sort of occult tower from "Lord of the Rings." "Just. Wow," Ayers tweeted. "As we went

These are the 15 best open source Android games you need to download

Andy Walker / Android Authority I’ve previously detailed a list of open source Android apps I always install on my phones, old or new. While all those apps add utility to my handsets, few of them provide pure entertainment. That’s where open source Android games come into play. Open source games might seem counterintuitive, but their transparency and alterability are part of their allure. They allow users to view their source code up and down or enjoy it as they are. Some have even spawned mod

Why government red tape is draining your phone’s battery potential

Robert Triggs / Android Authority You’re not alone if you’re pining for longer battery life from your latest smartphone. Despite emerging technologies like silicon-carbon cells, we’ve seemingly hit a ceiling just above the 5,000 mAh mark — at least for phones sold in the US and Europe. Meanwhile, glance over at models in China or India, and you’ll spot far larger batteries in otherwise identical handsets. For example, the new Nothing Phone 3 packs a 5,150mAh battery globally, but bumps that up
