The circular economy could make demolition a thing of the past

Most of us are already quite comfortable recycling our household waste. In Spain, for instance, millions of tonnes of packaging are processed every year, but did you know that buildings and their materials can also be recycled, or that an entire building could be completely dismantled and reassembled? Formula 1, often a laboratory for innovation, offers us a real-world example of this in the form of the Red Bull team’s “pit box”, known as the F1Holzhaus – literally, “the wooden house”. It made

When you're asking AI chatbots for answers, they're data-mining you

Opinion Recently, OpenAI ChatGPT users were shocked – shocked, I tell you! – to discover that their searches were appearing in Google search. You morons! What do you think AI chatbots are doing? Doing all your homework for free or a mere $20 a month? I think not! When you ask an AI chatbot for an answer, whether it's about the role of tariffs in decreasing prices (spoiler: tariffs increase them,); whether your girlfriend is really that into you; or, my particular favorite, "How to Use a Microwa

A short statistical reasoning test

The second – likelihoodist – is to create a profile likelihood and take the \(q\) quantile. I personally find this approach more intuitive in general because it is contextually picking model parameters, rather than to directly making claims about degrees of belief: we are just trying to pick \(p\) such that it captures the first 5% of the likelihood sum of our binomial model. There are at least two general – from first principles – approaches to calculate a lower bound fraction without knowing

These Are the Biggest Mistakes Home Cooks Make, According to Professional Chefs

Cooking can be intimidating. The process of shopping, prepping, cooking and, ultimately, tasting the fruits of your labor taps into a side of the brain that not many people can or want to explore. But not even the pros get it right all the time, as the kitchen provides a safe space to experiment, fail and -- best of all -- learn so that desired outcomes can be improved upon and new recipes can be added to the ever-growing arsenal. That said, it certainly helps to identify some of the most comm

Ars Technica System Guide: Four sample PC builds, from $500 to $5,000

Sometimes I go longer than I intend without writing an updated version of our PC building guide. And while I could just claim to be too busy to spend hours on Newegg or Amazon or other sites digging through dozens of near-identical parts, the lack of updates usually correlates with "times when building a desktop PC is actually a pain in the ass." Through most of 2025, fluctuating and inflated graphics card pricing and limited availability have once again conspired to make a normally fun hobby a

What Do Kids Actually Think About AI?

Ask an adult what they think about kids and AI, and expect to hear a strong opinion. Parents, politicians, experts—everyone has a take on whether young people should use AI, how to moderate their exposure, and how it’s changing the ways they think and communicate. Many of these opinions revolve around education. Adults fret that kids will turn ChatGPT into a research bot, paper writer, or math problem solver. Teachers, specifically, struggle to know how to deal with policing student use, and ho

Teachers Are Trying to Make AI Work for Them

One day last spring, in a high school classroom in Texas, students were arguing about who to kill off first. It was a thought experiment with a sci-fi premise: A global zombie outbreak has decimated major cities. One hundred frozen embryos meant to reboot humanity are safe in a bomb shelter, but the intended adult caretakers never made it. Instead, 12 random civilians stumbled in. There’s only enough food and oxygen for seven. The students had to decide who would die and who would live to raise

Tech in the Classroom: A History of Hype and Hysteria

If you’re a parent, an educator, or just someone who’s been to school, you’ve probably developed an opinion about generative AI in classrooms. You might fear the demise of the five-paragraph essay, the ever-increasing ease of cheating, or, worse, the end of critical thinking altogether. But don’t worry: The anxiety surrounding large language models in schools is anything but unprecedented. In 1975, teachers fretted that handheld calculators would undermine students’ capacity to “handle basic sk

How Microschools Became the Latest Tech Mogul Obsession

Elon Musk had a question: “Does anybody have any experience with first principles analysis?” He was speaking to a room full of kids, many of whom knew Musk as the CEO of companies that made rockets and cool-looking cars—and as the founder of Ad Astra, the microschool they attended in his Bel Air mansion, per a video posted by the YouTube channel Newsthink. To five of them, he was simply “Dad.” Generation iPad Young people entering classrooms this fall need a totally different tool set than the

I Prefer RST to Markdown (2024)

July 31, 2024 Why I prefer rST to markdown I will never stop dying on this hill I just published a new version of Logic for Programmers! v0.2 has epub support, content on constraint solving and formal specification, and more! Get it here. This is my second book written with Sphinx, after the new Learn TLA+. Sphinx uses a peculiar markup called reStructured Text (rST), which has a steeper learning curve than markdown. I only switched to it after writing a couple of books in markdown and decid

BBC Micro, ancestor to ARM

ARM-based chips are found in nearly 60 percent of the world’s mobile devices Introducing the “Beeb” – the inventors of the ARM architecture used these machines to simulate and develop chip designs. Those chips are now in every home and business. This particular machine is my BBC Master, plus 5 1/4″ floppy disk drive, and three-button mouse. Isn’t she a beauty? Like many microcomputers of the 1980s, the BBC Micro ran on a 6502 series microchip. Unlike most of the competition, however, the BBC

Fun with Finite State Transducers

ENOSUCHBLOG Programming, philosophy, pedaling. Aug 14, 2025 Tags: devblog, programming, rust, zizmor I recently solved an interesting problem inside zizmor with a type of state machine/automaton I hadn’t used before: a finite state transducer (FST). This is just a quick write-up of the problem and how I solved it. It doesn’t go particularly deep into the data structures themselves. For more information on FSTs themselves, I strongly recommend burntsushi’s article on transducers (which is wha

Modifying other people's software

Every once in a while, we all feel the need to modify something that someone else built. Sometimes those patches make sense to upstream, but not always. Sometimes they need a bit more time to bake, before they're ready to share with the world. Sometimes they're too specific to your environment. Sometimes it's just some personal preference, that the upstream wouldn't want to force upon everyone. And sometimes, just sometimes, you just want to run it yourself now, before it has had the time t

SystemD Service Hardening

Controversy aside, systemd provides us a very complete, robust method of controlling services (amongst a multitude of other Linux things). For a lot of things though, this is optimized for success out of the box and not necessarily security. Such is the way of many IT endeavors. This doc though is meant to provide a snapshot of a number of hardening options that you can apply to systemd service units and podman quadlets to increase the overall security posture and reduce both the likelihood of c

Google admits anti-competitive conduct involving Google Search in Australia

The ACCC has today commenced Federal Court proceedings against Google Asia Pacific over anti-competitive understandings that Google admits it reached in the past with Telstra and Optus regarding the pre-installation of Google Search on Android mobile phones. Google has co-operated with the ACCC, admitted liability and agreed to jointly submit to the Court that Google should pay a total penalty of $55 million. It is a matter for the Court to determine whether the penalty and other orders are app

Clojure Async Flow Guide

Flow Guide Getting started The flow library enables a strict separation application logic from the deployment concerns of topology, execution, communication, lifecycle, monitoring and error handling. Step fns and process launchers You provide logic to flow in the form of step-fns, which are wrapped into running processes, executing in a loop. Flow manages the life cycle of the process and handles incoming and outgoing messages by putting or taking them on channels. Step-fns do not access cha

PG Auto Upgrade – Docker (and K8s) container to auto upgrade your database

pgautoupgrade This is a PostgreSQL Docker image to automatically upgrade your database. Its whole purpose in life is to automatically detect the version of PostgreSQL used in the existing PostgreSQL data directory, then automatically upgrade it (if needed) to the required version of PostgreSQL using pg_upgrade with the --link option. After this, the PostgreSQL server starts and runs as per normal. The old cluster data will be removed. The reason this Docker image is needed, is because the of

ClickHouse matches PG for single-row UPDATEs and 4000 x faster for bulk UPDATEs

TL;DR · On identical hardware and data, ClickHouse matches PostgreSQL for single-row UPDATEs and is up to 4,000× faster in our tests for bulk UPDATEs. · Why it matters: Bulk updates are common in OLTP workloads, and ClickHouse’s columnar design + parallelism make them far faster. · Caveat: PostgreSQL is fully transactional by default; ClickHouse isn’t. Results compare each engine’s native execution model, not identical transaction guarantees. PostgreSQL is the most popular open-source

Why Nim?

You might have heard of the line, "one ring to rule them all" from the book the Lord of the Rings. Though, this ring is an evil object created by the evil Sauron, the idea of just one thing existing to manage or control a lot of things at the same time, is something we all long for. We all need that one app which can manage all our tasks. We need that one card that can hold or manage all our credit and debit card information. How we long for a single language for the whole world (by the way thi

A Visual Exploration of Gaussian Processes (2019)

Even if you have spent some time reading about machine learning, chances are that you have never heard of Gaussian processes. And if you have, rehearsing the basics is always a good way to refresh your memory. With this blog post we want to give an introduction to Gaussian processes and make the mathematical intuition behind them more approachable. Gaussian processes are a powerful tool in the machine learning toolbox . They allow us to make predictions about our data by incorporating prior kno

Show HN: NextDNS Adds "Bypass Age Verification"

We just shipped a new feature in NextDNS: Bypass Age Verification. More and more sites (especially adult ones) are now forcing users to upload IDs or selfies to continue. We think that’s a terrible idea: handing over government documents to random sites is a huge privacy risk. This new setting workarounds those verification flows via DNS tricks. It’s available today to all users, including free accounts. We’re curious how the HN community feels about this. Is it the right way to protect priva

The DC/Marvel Teamup Adds New Hero Duos To the Mix

So far, we’ve only known what’s coming from Marvel—now we know what DC’s bringing to the plate, and it’s a new batch of teamups featuring some of DC’s current big talents in charge of these stories. Per DC’s recent solicitations for November, DC/Marvel: Batman/Deadpool #1—written by Grant Morrison and drawn by Dan Mora

Material quality was a priority, and we kept an eye

‘Stranger Things’ creators may be leaving Netflix

Netflix could soon lose the creative team behind one of its biggest hits. Earlier this week, Variety and other Hollywood publications reported that Matt and Ross Duffer, the brothers who created “Stranger Things” (and wrote and directed many episodes), were in talks to sign an exclusive deal with Paramount (now under the ownership of David Ellison’s Skydance). Then on Friday evening, Puck’s Matthew Belloni posted that the Duffers had in fact “made their choice” and were going to Paramount. The
