Open source BOM management (for me)

Since graduating from university I’ve gotten more and more into embedded software development. This has even spilled over into designing PCBs (printed circuit boards) for my embedded devices to sit on. Initially I had assumed that the leap from software to hardware design would be insurmountable without any formal education but it turned out to be quite enjoyable. It turned out that the problem I’d be facing wasn’t a technical one, but of an organisational nature. Designing circuits Designing

New DNA Map of the Pistachio Could Create Better Varieties

California produces 99% of the nation’s pistachios, generating nearly $3 billion in economic value in the state. But pistachios have been slightly understudied in part because of the lack of a high-quality map of their DNA. University of California, Davis, researchers have now generated the most comprehensive genome sequence of the pistachio, allowing plant breeders to create better — perhaps more nutritious — varieties. They’ve also detailed how pistachio nuts develop, which will help farmers m

Friction and Not Being Touched

The journalist Karen Hao – who published an absolutely fantastic book about OpenAI called “Empire of AI” recently – coined (as far as I know) one of the best terms for describing modern “AI” systems: Everything Machines. “AI” systems are not framed as specific tools that solve specific problems in specific ways but just as solution in itself: There is nothing “AI” cannot do, if it fails we just failed it by not prompting it right or not building large enough data centers or not waiting for anot

I know when you're vibe coding

3 minute read I shouldn’t have to care about this. I don’t want to care about how someone’s code gets into the IDE. Whether you wrote it by hand, copied it from a forum, prompted an LLM, or ran a simulation where monkeys are given infinite time to produce the solution. I care about what gets merged into the codebase. When I click that “Approve” button, I’ve got only a few worries on my mind. Does it produce the correct outcome? Will people understand this next quarter? Will they be able to ch

150 years of Hans Christian Andersen

There once was an ugly duckling, so despised by the other birds that he fled the farm to explore the wider world. But because of his very great ugliness he was taunted there too, until one day he caught his image reflected in a pond and he had turned into a beautiful swan. The Ugly Duckling, first published in 1843, was one of Hans Christian Andersen’s many autobiographical fairy tales: “It matters nothing if one is born in a duck-yard,” he wrote, “if one has lain in a swan’s egg.” Andersen’s s

Tracking source locations in the Futhark compiler

Posted on July 29, 2025 Futhark is a programming language meant for writing fast programs, but as is the case for every programming language meant for writing fast programs, it inevitably happens that a programmer will use it to write a program that is not fast. When this happens, the programmer will likely want to know why their program is not fast, and how to make it faster. A useful tool for answering such questions is a profiler - a tool that tells you how long the different parts of your p

Attention is your scarcest resource

July 2020 Like many people, I have most of my best ideas in the shower. This is sometimes annoying: I could use more than one shower’s worth of good ideas a day, but I’d rather not end up as a shrivelled yet insightful prune. Mostly, though, shower ideas are the incentive that keeps me smelling okay, so I grudgingly accept the constraint. The time when it was most constraining was the first time I became a manager. I only had a few reports, so managing them wasn’t a full-time job. But I was v

Microsoft suddenly bans LibreOffice developer's email account, blocks appeal

Recap: The developers of LibreOffice, a free and open-source alternative to Microsoft Office, have repeatedly criticized Microsoft's proprietary software policies over the past few months. Although a recent incident involving Microsoft and a LibreOffice developer has no known connection to the rivalry, it could spark further criticism of the Windows provider. When LibreOffice developer Mike Kaganski attempted to send an email to the productivity suite's developer mailing list using a Hotmail ad

Meta profits surge helps drive Zuckerberg’s AI ambitions

Meta profits surge helps drive Zuckerberg’s AI ambitions Meta says the cost of building infrastructure, including servers and data centres, and workers' pay packages will be its biggest expenses. At the same time expenses are also rising - up 12% to $27bn - as the company ploughs money into fulfilling chief executive Mark Zuckerberg’s AI ambitions, and its spending is expected to keep rising. The firm - which owns Facebook, Instagram and WhatsApp - says revenue for the three months to the end

What screen time does to children's brains is more complicated than it seems

What screen time does to children's brains is more complicated than it seems 4 hours ago Share Save Zoe Kleinman • @zsk Technology editor Share Save BBC The other day, while I was doing some household chores, I handed my youngest child his dad's iPad to keep him entertained. But after a while I suddenly felt uneasy: I wasn't keeping a close eye on how long he had spent using it or what he was looking at. So I told him it was time to stop. A full-blown tantrum erupted. He kicked, he yelled, he

Meta's big AI spending blitz will continue into 2026

Meta CEO Mark Zuckerberg plans to continue his company's artificial intelligence spending blitz well into the next year as rival tech giants do the same.

The 10 apps I can't live or work without - on Windows, Mac, and mobile

berkozel/Getty Images Every five years or so, I make an inventory of the apps I use most frequently. It's always fascinating to see how the list has changed over time, and it usually says something about the computing landscape. When I did that exercise this year, I was astonished at the changes. Half of the apps I used five years ago are no longer on my list at all in 2025. They've been replaced, in most cases, by apps that are tightly linked with web-based services and cloud storage and can

Show HN: Open-source physical rack-mounted GUI for home lab

The enclosure mounts as a 2U unit. 1U form factor was a bit challenging to pull off but I can try again. I have realized that a lot of people nowadays self-host services and set up home labs with mini racks. A significant challenge I've personally encountered is quickly obtaining health status from self-hosted services and machines, along with having the capability to control my Raspberry Pi headlessly within a mini rack. So, it got me thinking about creating a built-in GUI that users

Fixing Ctrl+C in Rust terminal apps: Child process management

When a terminal application that spawns child processes doesn't exit cleanly after a Ctrl+C , the user is left with a corrupted terminal. Instead of a clean prompt, you get garbled output and a non-functional shell. This post covers how to solve these issues, with examples from the Moose CLI (for the PR that fixed many of these issues, see here). In this post, you’ll read learnings from solving these issues in the Moose CLI— terminal application that manages multiple child processes, including

Ferroelectric helps break transistor limits

Integrating an electronic material that exhibits a strange property called negative capacitance can help high-power gallium nitride transistors break through a performance barrier, say scientists in California. Research published in Science suggests that negative capacitance helps sidestep a physical limit that typically enforces trade-offs between how well a transistor performs in the “on” state versus how well it does in the “off” state. The researchers behind the project say this shows that n
