The Perils of 'Design Thinking'

On the first day of a required class for freshman design majors at Carnegie Mellon, my professor stood in front of a lecture hall of earnest, nervous undergraduates and asked, “Who here thinks that design can change the world?” Several hands shot up, including mine. After a few seconds of silence, he advanced to the next slide of his presentation: a poster by the designer Frank Chimero that read, Design won’t save the world. Go volunteer at a soup kitchen, you pretentious fuck. My professor was

Sequence and first differences together list all positive numbers exactly once

EXAMPLE Sequence reads 1 3 7 12 18 26 35 45..., differences are 2 4 5, 6, 8, 9, 10 ... and the point is that every number not in the sequence itself appears among the differences. This property (together with the fact that both the sequence and the sequence of first differences are increasing) defines the sequence!

Using the internet without IPv4 connectivity

Using the Internet without IPv4 connectivity A few days ago my ISP broke the IPv4 connectivity from my router after a power cut. Fortunately IPv6 connectivity still worked fine, but only a small fraction of websites were accessible. In this post I'll cover how Linux, WireGuard, and Hetzner came to the rescue - keeping the whole internet usable with only an IPv6 connection. Opinions expressed are solely my own and do not express the views or opinions of my employer. Background One morning I

I Let AI Agents Plan My Vacation—and It Wasn't Terrible

The worst part of travel is the planning: the faff of finding and booking transport, accommodation, restaurant reservations—the list can feel endless. To help, the latest wave of AI agents, such as OpenAI’s Operator and Anthropic’s Computer Use claim they can take these dreary, cumbersome tasks from befuddled travelers and do it all for you. But exactly how good are they are digging out the good stuff? What better way to find out than deciding on a last-minute weekend away. I tasked Operator, w

The Best Printers for Home and Office: Brother, HP, and More

Before anything else, you'll have to decide between ink and laser. I'll get into the details when it comes to each model, but the most important consideration is paper type, because it’s a limitation rather than a benefit. Laser printers use heat in the bonding process, which means if you regularly print on windowed envelopes or photo paper, you'll need to either use an ink printer or change to a thermally-safe alternative, which can be cost prohibitive if you print a lot. Inkjets are the most

iPhone 17 Pro may reposition the Apple logo once again, says leaker

According to Apple leaker Majin Bu, Apple will once again be repositioning the Apple logo on the next iPhone. Apple last repositioned the Apple logo with the iPhone 11 lineup, and it’s remained centered on the iPhone ever since. Six years later, that may be changing once again – if this rumor holds up. Majin Bu has a spotty track record with Apple rumors, though they have shared a number of accurate tidbits in the past, including the ‘Desert Titanium’ marketing name for the new iPhone 16 Pro co

Infrastructure at Roblox

Throttling is a very accepted concept in computer science. But this is the most misused and misunderstood lever of computer science. When new engineers join Roblox, their first solutions often include, “If we could just tell our creators to tweak this config or slow down their events…”. Veteran Roblox engineers then gently explain our value of respecting the community and that we don’t tell our creators what to do. For example, most gaming systems have a simple solution for matchmaking when mil

Against AI: An Open Letter from Writers to Publishers

To Penguin Random House, HarperCollins, Simon & Schuster, Hachette Book Group, Macmillan, and all other publishers of America: We are standing on a precipice. At its simplest level, our job as artists is to respond to the human experience. But the art we make is a commodity, and our world wants things quickly, cheaply, and on demand. We are rushing toward a future where our novels, our biographies, our poems and our memoirs—our records of the human experience—are “written” by artificial intell

We ran a Unix-like OS Xv6 on our home-built CPU with a home-built C compiler (2020)

How we ran a Unix-like OS (Xv6) on our home-built CPU with our home-built C compiler [Thanks for many comments and votes on Hacker News! ] It’s been two years since I started working as a software engineer. I sometimes tell my colleagues about a student project I did in my junior year of university, and it’s so well-received that I’m writing this post. Now, let me ask you a question. Have you ever designed your own ISA, built a processor of that ISA on FPGA, and built a compiler for it? Furth

Refurb weekend: Gremlin Blasto arcade board

My general vintage computing projects, mostly microcomputers, 6502, PalmOS, 68K/Power Mac and Unix workstations, but that's not all you'll see.

The Death of the Middle-Class Musician

Rollie Pemberton was barely a teenager when he started rapping. His hometown, Edmonton, didn’t have much of a hip-hop scene in the early aughts, so he honed his craft online. He plugged an old-school microphone into his mom’s desktop computer, recorded a few verses, later turned them into tracks, and sent them out into the burgeoning music blogosphere. Within a few years, he’d adopted the emcee name Cadence Weapon and earned a reputation as a shrewd critic and sharp lyricist. This work didn’t p

Solving `Passport Application` with Haskell

There's a trend at the moment of solving online games with programming, let's do one from the UK called Passport Application, which is developed by "His Majesty's Passport Office" or HMPO. It's a cultural phenomenon in the UK: despite being quite expensive (about £100 just to start) for the standard online version (a masterpiece of minimalist design, entirely text-based), most British play the game, and do so every 10 years or so. It's an adventure puzzle document collection game. The premise i

Brother printer hack puts thousands of users at risk of remote takeover

TL;DR: Hackers have cracked Brother's method of generating default admin passwords for hundreds of its printers, scanners, and label makers, putting users who haven't changed them at risk. Additionally, researchers found seven other serious vulnerabilities affecting Brother and other brands. Users should visit company websites for security advisories and update their firmware. Security researchers at Rapid7 recently reported eight vulnerabilities affecting over 689 printers, scanners, and label

Android 16 will alert users to possible Stingray surveillance, fake cell towers

Why it matters: As Android 16's new security features roll out with the next generation of smartphones, users will, for the first time, have a tool to detect invisible digital surveillance. Whether this prompts broader reforms in how such technology is used and regulated remains to be seen. Still, the feature reflects a growing awareness of the need to protect personal privacy in the mobile age. An upcoming Android update will introduce a warning system to help users detect one of the most elus

Tesla shows off its first fully autonomous delivery to convince us its self-driving cars work well

Tesla's robotaxi service may have had some early hitches, but the company said it just successfully delivered a car autonomously. Using the same robotaxi technology, Tesla showed the delivery process of a Model Y from its Gigafactory Texas in Austin to a customer with a roughly 30-minute journey as seen in a video posted on X. Unlike the robotaxi service launch last week, the automated delivery had no safety monitor, nor anyone behind the wheel. Tesla's CEO, Elon Musk, also posted on X that the

The Great Illusion: When We Believed BeOS Would Save the World

A nostalgic dive into the Hacker News thread that in 2015 reminded us how beautiful we were when we dreamed in multithreading Once upon a time, in a galaxy not so far away called “the ’90s,” we still believed that the future of computing would be decided based on pure technical merit. What naivety! It was an era when an operating system could make you fall in love at first boot, when opening four videos simultaneously without hiccups seemed more magical than pulling a rabbit from a hat. BeOS wa

Evaluating Long-Context Question and Answer Systems

While evaluating Q&A systems is straightforward with short paragraphs, complexity increases as documents grow larger. For example, technical documentation, novels and movies, as well as multi-document scenarios. Although some of these evaluation challenges also appear in shorter contexts, long-context evaluation amplifies issues such as: Information overload: Irrelevant details in large documents obscure relevant facts, making it harder for retrievers and models to locate the right evidence for

The Book Cover Trend of Text on Old Paintings

Like fashion trends, fads in book covers come and go. One year, the backs of women’s heads might be all the rage; the next, soft focus photography. And who can forget the exploding flower craze? Or the proliferation of flames on jackets, from thrillers to science fiction to self-help? But the look that’s commanding today’s runways — a.k.a. bookshelves — is not so incendiary. It tends to lay blaringly bright type in a sans-serif font atop a painting, usually a few centuries old but not always. F

‘Predator: Badlands’ Joins Disney’s San Diego Comic-Con Plans

The hunt will be on at San Diego Comic-Con, where Predator: Badlands will get the spotlight. Per the Hollywood Reporter, the sci-fi film will get a Hall H panel during the convention weekend. It’ll be the second big Disney movie of the fall season to make an appearance at the famed Hall, joining October’s Tron: Ares. Both films will fill in for a lack of Marvel at this year’s convention, and it’ll be the Predator franchise’s first theatrical movie to hit SDCC since Shane Black’s 2018 reboot. (P

Are TikTok Age Tests Legit? Orthopedists Explains How to Measure Biological Age

If you’ve scrolled through TikTok or Instagram, you’ve probably seen fitness challenges based on your biological age. In some cases, it’s funny to see people attempting feats that seem impossible for their age or impressive that they can do them. You’ve probably felt inspired to try out some of these challenges and even questioned their legitimacy. “Most of these challenges, like completing 11 consecutive push-ups (for women), doing pull-ups or performing a kneeling-to-squat jump, are quick scr

2025’s Best 3D Printers Are the Best I’ve Seen in a Decade

What I like: I rarely find a product that impresses me, but the A1 Combo from Bambu Lab left me genuinely amazed with its performance and value. This 3D printer is excellent, with fast, quality printing at a great price. Adding the AMS Lite elevates it to the best printer you can buy right now. Plus, its four-color printing capability for less than $700 is such a good deal; I'm still baffled by how the company pulls off that pricing. The CNET test print from the Bambu Lab A1 is nearly perfect.

The AI Backlash Keeps Growing Stronger

Before Duolingo wiped its videos from TikTok and Instagram in mid-May, social media engagement was one of the language-learning app’s most recognizable qualities. Its green owl mascot had gone viral multiple times and was well known to younger users—a success story other marketers envied. But, when news got out that Duolingo was making the switch to become an “AI-first” company, planning to replace contractors who work on tasks generative AI could automate, public perception of the brand soured

Facebook is asking to use Meta AI on photos in your camera roll you haven’t yet shared

Facebook is asking users for access to their phone’s camera roll to automatically suggest AI-edited versions of their photos — including ones that haven’t been uploaded to Facebook yet. The feature is being suggested to Facebook users when they’re creating a new Story on the social networking app. Here, a screen pops up and asks if the user will opt into “cloud processing” to allow creative suggestions. As the pop-up message explains, by clicking “Allow,” you’ll let Facebook generate new ideas

Authors call on publishers to limit their use of AI

In Brief An open letter from authors including Lauren Groff, Lev Grossman, R.F. Kuang, Dennis Lehane, and Geoffrey Maguire calls on book publishers to pledge to limit their use of AI tools, for example by committing to only hire human audiobook narrators. The letter argues that authors’ work has been “stolen” by AI companies: “Rather than paying writers a small percentage of the money our work makes for them, someone else will be paid for a technology built on our unpaid labor.” Among other c

Nvidia RTX 5060 Ti 8GB vs. 16GB Tested Across PCIe 3.0, 4.0 and 5.0

Recently we examined how PCI Express bandwidth influences the performance of the 8 GB Radeon RX 9060 XT when local video memory (VRAM) is exceeded. The entire purpose of that testing was to push past the VRAM limit, which, unfortunately for 8 GB graphics cards, is a relatively easy task in 2025. This can happen even when using settings that would otherwise be highly playable, as demonstrated by the 16 GB model. This is an interesting test for several reasons, the most notable being that PCIe ba
