After a partly successful test flight, European firm eyes space station mission

Last month, the parachutes on Hélène Huby's small spacecraft failed to deploy, and the vehicle and its cargo crashed into the ocean on Earth. It was both a success and a failure. The success was that after Huby founded The Exploration Company in Europe, she managed to move nimbly with the "Mission Possible" spacecraft such that it cost less than $25 million to build and reached space in less than three years. The vehicle ticked off a number of successes in spaceflight before making a controlle

USB-C hubs and my slow descent into madness (2021)

2021-04-25 2022-10-14 electronics, hardware Just to start this off on a fun note: this article is not a review. This fact will become clear later on, but I figured it’s worth highlighting that just in case somebody finds this text via their search engine of least distrust. I have one of those laptops lacking a lot of accessory ports. In fact, I’m writing this on an Apple MacBook Pro, and all I got was four lousy USB-C ports. If I want to connect pretty much anything, I need some sort of adapte

GitHub abused to distribute payloads on behalf of malware-as-a-service

Researchers from Cisco’s Talos security team have uncovered a malware-as-a-service operator that used public GitHub accounts as a channel for distributing an assortment of malicious software to targets. The use of GitHub gave the malware-as-a-service (MaaS) a reliable and easy-to-use platform that’s greenlit in many enterprise networks that rely on the code repository for the software they develop. GitHub removed the three accounts that hosted the malicious payloads shortly after being notified

I've used Aqara's first outdoor camera for over four months now - Here's my verdict

ZDNET's key takeaways The Aqara Camera Hub G5 Pro is typically available for $180 for the Wi-Fi version and $200 for the PoE version. This indoor/outdoor security camera doubles as a smart home hub, features 1520p resolution for crystal-clear images, RTSP support, and has a built-in NPU to process video with AI for visual recognition. The camera is wired, so placement is limited, and there is no expandable storage, so you need a subscription to access video history or bypass it through video s

These four charts show where AI companies could go next in the US

While the impact of AI on tech hubs like San Francisco and Boston is already being felt, AI proponents believe it will transform work everywhere, and in every industry. The report uses various proxies for what the researchers call “AI readiness” to document how unevenly this supposed transformation is taking place. Here are four charts to help understand where that could matter. 1. AI development is still highly focused in tech hubs. Brookings divides US cities into five categories based on h

James Webb, Hubble space telescopes face reduction in operations

The James Webb Space Telescope is pictured here before being folded up for launch. Credit: NASA Key Takeaways: NASA's Hubble and James Webb telescopes face operational cuts due to budget limitations. Reduced funding may lead to fewer available telescope modes and less user support. Hubble's budget has remained flat for a decade, decreasing its purchasing power. “It’s fewer people, really,” said Neill Reid. The teams operating the Hubble Space Telescope and James Webb Space Telescope (JWST)

Switching to Claude Code and VSCode Inside Docker

Last night I finished a transition from my old AI coding setup I've been using for a while to running Claude Code in Docker using VSCode's "Dev Container" feature. In this post I lay out a few of my thoughts on why I wanted to switch to something in the first place, and also a short guide for those who want to do the same. If you are here just for the guide + code (a tiny single file), here it is: https://github.com/tim-sha256/claude-in-docker 🥺 Important note! I'm not a professional vibe

8 Best USB Hubs (2025), Tested and Reviewed

There are various generations of USB, with different capabilities and speeds, plus ports that look similar but do other things. There are a few key terms you should know when shopping for a USB hub: USB 2.X/USB 3.X/USB 4: Every USB device is built to some version of the USB specification, mainly characterized by how much data they can transfer and how much power they can deliver (or at least, those are the main things you need to care about). While most of these devices are inter-operable as lo

Regarding Prollyferation: Followup to "People Keep Inventing Prolly Trees"

Last month I published a blog post about the parallel invention of Prolly Trees, where I observed the repeated independent invention of a certain type of data structure within a relatively short period of time. In short, I described the concept of a Merkle Tree created by applying a content-defined chunker to a file, hashing the chunks, and then recursively reapplying the chunker to the concatenated list of hashes until only a single chunk remained. Each iteration of this process defined a sepa

Life after two-stroke: Rotax electrifies its bike and kart powertrains

Rotax provided flights from San Francisco to Salz, Austria, and accommodation so Ars could visit its factory and ride some of its products. Ars does not accept paid editorial content. "There was always a passion about motorbikes. But it's not only passion, it also needs to be a sustainable business model," Mario Gebetshuber, BRP-Rotax vice president of global sourcing and operations powertrain, told Ars Technica during a tour of the company's museum of motors over the decades. Gebetshuber says

Proposal: GUI-first, text-based mechanical CAD inspired by software engineering

Most mechanical CAD tools (SolidWorks, Fusion, FreeCAD) still lock all modeling into opaque binary files. That makes it hard to track changes, collaborate with Git, or automate builds. I’ve written a proposal for an alternative paradigm: - GUI-first, like KiCad - visual modeling is the default - Text-based source files (YAML/JSON) — readable, diffable, Git-friendly - Separation of source and result - .step, .stl and previews are built artifacts - Parametric logic is explicit - slot width =

New Research Bolsters Freaky Theory That Earth Sits in a Giant Cosmic Void

Images of the cosmos, such as the James Webb Space Telescope’s deep space snapshot, make space look chock-full of stuff. In the grand scheme of things, it is, but all those stars, galaxies, planets, and other celestial objects may not be as uniformly distributed as photos make them look. The fact is, space is likely peppered with bubbles of relative emptiness, and some astronomers believe we’re sitting inside of one. A growing body of evidence suggests that our entire Milky Way galaxy is locate

The uncertain future of coding careers and why I'm still hopeful

The Uncertain Future of Coding Careers and Why I'm Still Hopeful A friend of mine, bright, driven, and relatively new to programming, asked me a heavy question the other day. “Did I make a mistake? Did I choose the right career?” The question hung in the air. It wasn’t born from a bad day or a frustrating bug. It came from a much deeper place of anxiety, one that I suspect many in our industry are feeling right now. They saw recent waves of layoffs, they read the headlines about Artificial Int

I scanned all of GitHub's "oops commits" for leaked secrets

TL;DR GitHub Archive logs every public commit, even the ones developers try to delete. Force pushes often cover up mistakes like leaked credentials by rewriting Git history. GitHub keeps these dangling commits, from what we can tell, forever. In the archive, they show up as “zero-commit” PushEvents . I scanned every force push event since 2020 and uncovered secrets worth $25k in bug bounties. Together with Truffle Security, we're open sourcing a new tool to scan your own GitHub organization for

Google’s spotty Find Hub network could get better thanks to a small setup tweak

Bluetooth trackers have existed for quite a while, but Apple made them worthwhile when it enlisted every iPhone to support AirTags. The tracking was so reliable that Apple had to add anti-stalking features, and there are just as many Android phones out there. However, Google's version of mobile device tracking, known as Find Hub, has been comparatively spotty. Now, Google is about to offer users a choice that could fix Bluetooth tracking on Android. According to a report from Android Authority,

Google’s Find Hub network is unreliable, but this simple change could fix it

Andy Walker / Android Authority TL;DR Google could improve its Find Hub network by convincing users during device setup to select a more reliable, but less private, tracking option. This new setup screen rebrands the existing network options to better explain that the default option may be less reliable, while the alternative can find items anywhere. By getting more people to choose the more effective setting, Google aims to make its network a more dependable alternative to Apple’s and Samsun
