Poltergeist The ghost that keeps your builds fresh 👻 A universal file watcher with auto-rebuild for any language or build system Poltergeist is an AI-friendly universal file-watcher that auto-detects any project and rebuilds them as soon as a file has been changed. Think npm run dev for native apps, with automatic configuration, notifications and a smart build queue. It stands on the shoulders of giants and fills the glue layer that's been missing. Works on macOS, Linux, and Windows. Availabl
500 virtual Linux devices on ARM 64 Underjord is an artisanal consultancy doing consulting in Elixir, Nerves with an accidental speciality in marketing and outreach. If you like the writing you should really try the pro version. This is the first part of an experimental journey as I explore how many instances of my favorite IoT framework I can run on the 192 core Ampere One. Background I work on the Nerves project which is an IoT framework providing best-practice underpinnings and support so

During today’s Oval Office press conference, President Donald Trump announced that Apple will be exempt from an upcoming “very large tariff on chips and semiconductors”. Here are the details. Today, Apple announced the American Manufacturing Program (AMP), adding $100 billion to its previously pledged $500 billion investment aimed at expanding domestic facilities and creating jobs. During the press briefing in which, among other things, Apple CEO Tim Cook gifted President Trump a piece of US-m

Posts from this author will be added to your daily email digest and your homepage feed. In the very first week of his presidency, Donald Trump vowed to force silicon manufacturing back to the United States by making processors more expensive, a threat he’s repeated since. Is he finally going through with that plan? Trump just announced he’
Some patterns I have started to use when writing zig code with unit tests. Introduction Although I try to make good use of the debugger, I am quite used to print-based debugging, especially for unit tests. I wanted to explore some tricks to improve print-based debugging, and also incorporate the debugger more. print-based debugging improved One big problem with using print debugging is spammy output. If I am running something in a loop, and only one iteration of the loop has anything interes
An ill wind blows through the automotive industry. Yesterday, after the market closed, Rivian reported its results for the second quarter of 2025, and they weren't great. Unlike the last two quarters, Rivian did not make a gross profit, and it's estimating it will have a larger loss this year than first predicted. A day earlier, it was Lucid's turn: The Saudi-backed EV startup also missed analyst estimates for the quarter, and Lucid says it will build fewer cars this year than originally planned

Finding product-market fit isn’t a milestone — it’s a messy, make-or-break journey. And at TechCrunch Disrupt 2025, a founder who’s been through the fire and two investors who’ve helped startups hit escape velocity will break down how to do it right. On the Builders Stage, Rajat Bhageria (Founder & CEO, Chef Robotics), Ann Bordetsky (Partner, NEA), and Murali Joshi (Partner, ICONIQ) join forces to unpack the most critical — and elusive — phase in a startup’s life cycle. They’ll dive into smart

The sharpest criticisms of the book Abundance have sometimes come from the antitrust movement. This group, mostly on the left, insists that the biggest problems in America typically come from monopolies and the corruption of big business. In housing, for example, Ezra Klein and I write that a key bottleneck to homebuilding in the last few decades has been legal barriers to construction, including zoning laws and minimum lot sizes. This is a mainstream view supported by economists and scholars w

If you’re a developer rocking an Apple Silicon Mac and writing in Zig, congratulations - you’ve chosen the scenic route through the desert of profiling tools. It’s just you, your code, and a tumbleweed named Apple Instruments. But don’t worry - we’ll try to find some oases. Okay, it’s not that bad, but we’re far away from the rich ecosystem of profiling tools available on Linux. Note: I have limited experience using low-level languages, so this article doesn’t provide a deep dive into profili
Despite widespread confusion, Andrej Karpathy coined "vibe coding" as a kind of AI-assisted coding where you "forget that the code even exists." Legacy code We already have a phrase for code that nobody understands: legacy code. Legacy code is universally despised, and for good reason. But why? You have the code, right? Can't you figure it out from there? Wrong. Code that nobody understands is tech debt. It takes a lot of time to understand unfamiliar code enough to debug it, let alone intro
Epistemic status: Main part is well-supported but may have some minor errors. The parts about potential future lines are inherently speculative. Small Train is Good Train A while ago, I wrote about how elevated trains are the greatest urbanism cheat code, increasing the amount of track miles you can build per dollar (or per year) by a factor of 2-4. And while I don’t have anything else on that order of magnitude, I do have one more easy 20-50% gain: Run shorter trains. The basic idea is simpl
We don’t want to bury the lede: we have raised a $100M Series B, led by a new strategic partner in USIT with participation from all existing Oxide investors. To put that number in perspective: over the nearly six year lifetime of the company, we have raised $89M; our $100M Series B more than doubles our total capital raised to date — and positions us to make Oxide the generational company that we have always aspired it to be. If this aspiration seems heady now, it seemed absolutely outlandish w
“The fun of an Avengers movie is introducing people to each other and seeing how very different personalities get along,” says Kevin Feige, the president of Marvel Studios. “In the case of a movie that involves the threat of worlds literally colliding, it’s fun to see them visit each other’s homes.” Feige was speaking to the official Marvel website about The Fantastic Four: First Steps, which is now in theaters. It’s the final piece of the puzzle before Avengers: Doomsday comes out in December
Popular open source 3D modeling tool Blender's social media channels and subreddit have regularly seen people asking for a tablet version for years now. And according to a blog post by Dalai Felinto from the Blender team, the developers of the application have now committed to build just that. "The idea is to bring the full power of Blender to these devices," the blog post explains. "This requires adapting to platform-specific paradigms, but also to offer more task-oriented user interfaces with

Today we're excited to announce OSS Rebuild, a new project to strengthen trust in open source package ecosystems by reproducing upstream artifacts. As supply chain attacks continue to target widely-used dependencies, OSS Rebuild gives security teams powerful data to avoid compromise without burden on upstream maintainers. The project comprises: Automation to derive declarative build definitions for existing PyPI (Python), npm (JS/TS), and Crates.io (Rust) packages. SLSA Provenance for thousan

There’s a theory about housing that has taken hold with a kind of religious fervor: If you want to make housing more affordable, just build more of it. Supply and demand. Simple economics. This narrative is now dominating housing policy discussion across the political spectrum. Deregulate, upzone, speed up approvals, let the market work. And if you build enough homes, the theory goes, prices will come down. But here’s the question almost no one asks: What happens when prices actually start to
Debian packaging is notoriously hard. Far too many new contributors give up while trying, and many long-time contributors leave due to burnout from having to do too many thankless maintenance tasks. Some just skip testing their changes properly because it feels like too much toil. Debcraft is my attempt to solve this by automating all the boring stuff, and making it easier to learn the correct practices and helping new and old packagers better track changes in both source code and build artifac
Embrace the Grind: 15 Years of Building Jefit The Start of Something I Didn't Expect to Last 15 Years Fifteen years ago, Jefit wasn't a company. It wasn't even a business idea. It was just a project I started in my dad's living room in North Carolina, fresh out of college, working from my own laptop. I was broke and unsure about the future, frustrated by how hard it was to track workouts. There was no easy way to stay consistent or see real progress. I wasn't chasing a startup dream, jus
