Mysterious Signals From Deep Space Expose Aftermath of Failed Cosmic Eruptions

Whenever we study space, we’re usually talking about long-lasting objects, like our own solar system or faraway galaxies that occasionally catch our attention when something extraordinary happens. But sometimes, the universe sends us quick, random bursts of energy that are usually too far away and too ephemeral for scientists to make any sense of—like fast X-ray transients (FXTs), whose elusive origins have long evaded astronomers. Recently, however, astrophysicists had a lucky strike: spotting

Whole-genome ancestry of an Old Kingdom Egyptian

Provenance and ethics The human remains were excavated from the Nuwayrat necropolis near Beni Hasan, Egypt. They were donated between 1902 and 1904 by the Egyptian Antiquities Service to the members of the Beni Hasan excavation committee and subsequently donated to the Institute of Archaeology, University of Liverpool and exported under the John Garstang export permit. The human remains were then donated to the World Museum (previously the Liverpool City Museum) in 1950. Sampling permit was gra

BusyBeaver(6) Is Quite Large

For overdetermined reasons, I’ve lately found the world an increasingly terrifying and depressing place. It’s gotten harder and harder to concentrate on research, or even popular science writing. Every so often, though, something breaks through that wakes my inner child, reminds me of why I fell in love with research thirty years ago, and helps me forget about the triumphantly strutting factions working to destroy everything I value. Back in 2022, I reported an exciting advance in BusyBeaverolo

Military Launches Website to Find Big Tech’s ‘Army Strong’ Employees

If you’re working in Big Tech and looking to make an exit, the Army is waiting with open arms. Someone’s gotta build the tech to drop these bombs, after all. Task and Purpose reports that the Army’s Talent arm has launched Detachment 201, an initiative to pull technology professionals into the military’s ranks—the latest in a growing pipeline between Silicon Valley and the U.S. Armed Forces. The Detachment 201 effort has put out the call for “top-tier, uniquely skilled technology professionals”

Ask HN: Anyone Using Augmented Reality, VR, Glasses, Helmets etc. in Industry?

Since Google Glass made its debut in 2012, there's been a fair amount of hype around augmented reality and related tech coming into its own in industry, presumably enhancing worker productivity and capabilities. But I've heard and seen so little use in any industries. I would have thought at a minimum that having access to hands-free information retrieval (e.g. blueprints, instructions, notes, etc), video chat and calls for point-of-view sharing, etc would be quite useful for a number of indust

US Army Appoints Palantir, Meta, OpenAI Execs as Lt. Colonels

Four senior executives at Palantir, Meta, and OpenAI have been formally appointed lieutenant colonels in the US Army following the creation of a “special” unit created for rich Big Tech mavens seeking military leadership roles. On June 13, the Army announced the creation of Detachment 201, otherwise known as the “Executive Innovation Corps,” which it describes as “a new initiative designed to fuse cutting-edge tech expertise with military innovation.” Four ultra-wealthy executives from top tec

Over 46,000 Grafana instances exposed to account takeover bug

More than 46,000 internet-facing Grafana instances remain unpatched and exposed to a client-side open redirect vulnerability that allows executing a malicious plugin and account takeover.

The vulnerability was discovered by bug bounty hunter Alvaro Balada and was addressed in security updates that Grafana Labs released on May

Bits and bobs related to Wireless-Tag's WT32-ETH01 board

Unofficial guide to the WT32-ETH01 What is this thing and why would I use it? The WT32-ETH01 is effectively a small, cheap ESP32 development board with Ethernet, WiFi, and GPIO pins, made by a company called "Wireless-Tag" (WT). As of this writing, it's around $15 at JacobsParts and around $7 from AliExpress. There aren't a ton of ESP32 boards with Ethernet, and the WT32-ETH01 is by far the smallest, cheapest, and simplest. (The OLIMEX ESP32-POE and wESP32 are the other notable options.) So,

The $230 MacBook Air Is Real, It’s a Steal, and It’s Flying Off the Shelves

MacBooks are many things — beautifully designed, reliable, sturdy, fast, and powerful among them. Inexpensive, however, is not a word you hear applied to MacBooks often, if ever. Apple is very much a get-what-you-pay-for company, and you pay for quality. Thankfully, there are shortcuts to be found, like the deals StackSocial frequently runs on Grade-A refurbished MacBooks for a fraction of their usual cost.

ProtoArc XKM01 CaseUp Combo Review: A Reliable Portable Workstation

The mouse is perfectly adequate too. It's slim but provides enough palm support that my hand doesn't feel like it's cramping up. The scroll wheel and buttons are smooth and responsive. After a short time, I noticed a strange, squeaky noise coming from the left side whenever I'd click. It's not always there, but it's slightly annoying whenever it comes back. Like the keyboard, it charges via USB-C but has a slightly longer battery life of up to 200 days (standby time). The stand is super adjusta
