alternative_right shares a report from Phys.org: Optical fibers are already the backbone of global communication systems. Recently, however, physicists have started to explore how their functionality could be boosted further by conveying information via entangled quantum particles -- potentially enabling instantaneous exchanges of information across vast distances. Such a system could eventually be the basis of a future 'quantum internet,' offering a level of security and computing power beyond anything possible today. In new research published in Physical Review Letters, a team led by Xi-Yu Luo at the University of Science and Technology of China in Hefei has pushed that vision further than ever, entangling two quantum memories across 420 kilometers (261 miles) of optical fiber -- more than four times the previous record.

An anonymous reader quotes a report from The Guardian: The release of a new album by Taylor Swift might be a cause for celebration among her fans, but such events have also been linked to a more sombre phenomenon: an increase in fatal car crashes. The team behind a new study say it sheds light on the impact of distracted driving. Writing in the journal Jama Network Open, [Vishal Patel, first author of the study based at Harvard Medical School] and colleagues report how they focused on the release of 10 major albums, launched between 2017 and 2022, selected for having the highest number of Spotify streams over a single day. [...] The team found streaming volume for the top 200 songs in the US was 43% higher on the date of major album releases compared with the days surrounding the releases -- although such data does not reveal whether the music was being streamed in a car. [...] The researchers used data from a population-based registry of fatal US motor vehicle crashes to look at the number of traffic fatalities on the dates these albums were released, as well as for the 10 days either side. After taking into account the day of the week upon which the album was released, as well as federal holidays, and time of year, the researchers found the number of US traffic fatalities showed a relative increase of 15.1% on the date of major album releases, compared with similar days either side. "This is equivalent to approximately 182 fatalities in the US attributable to the release days of the 10 included albums," the team writes. Patel said the release of a new album could distract drivers because accessing music is a search task, not a single button press. "You unlock the phone, open the app, find the release, read down a tracklist, tap the right song. That's several seconds of looking at a screen," he said, adding unfamiliar music also demands more attention, while research has suggested listening to new, high-energy music measurably degrades driving performance. The researchers add the rise in traffic fatalities was greater among certain groups -- such as younger drivers, male drivers, people who were driving alone, and people driving cars with a built-in infotainment platform. The authors say the results suggest that "online music streaming through smartphones may significantly contribute to distracted driving and traffic fatalities."

Cursor has launched Origin, a GitHub-style code hosting platform built directly into its AI coding environment. The company is initially positioning Origin as a low-risk layer on top of GitHub, keeping GitHub as the "source of truth," but the launch landed just as a major GitHub outage highlighted growing concerns about reliability in the age of AI-generated code. VentureBeat reports: Cursor began rolling out Origin, its own code hosting platform, to paid users on Monday morning. Roughly three and a half hours later, GitHub's status page lit up with what became a six-hour-and-forty-two-minute global degradation -- error rates near 20% across pull requests, issues and the API, and near 50% on archive and raw file downloads, according to GitHub's incident log. Enterprise single sign-on went down with it: SAML, OIDC, SCIM provisioning and Team Sync all failed. So did Copilot. The developer internet did what the developer internet does. "You can now host your repos in Cursor Origin and deploy to Vercel via Cursor Origin which is itself hosted on Vercel," Vercel chief executive Guillermo Rauch posted on X. "And unlike GitHub, it's online [smile emoji]" Asked why he was smiling, Rauch replied: "trying to make light of the situation. We ourselves are stuck because of github rn!" Matt Palmer, who works at Cursor, quote-tweeted his own company's launch with the day's best line: "We were going to ship this earlier, but GitHub was down." A GitHub outage, in other words, delayed the launch of a GitHub competitor. Product launches get locked weeks in advance, and no evidence suggests Cursor timed this one. But the coincidence did the company an enormous favor, because it dramatized the argument Origin exists to make. For eighteen years, choosing where to host your team's source code has been the least interesting decision an engineering organization makes. Cursor is betting that AI agents have made it interesting again -- and for technical decision makers, that is the real news here. Not a new product, but a new procurement question with a governance problem attached.

A great and concise history of the run-up to MS-DOS 2.0. Yet, there was a nagging feeling that a single-tasking CP/M clone was inadequate for the new generation of personal computers. Digital Research released multi-user, multitasking MP/M-86 in September 1981 and announced the single‑user multitasking Concurrent CP/M in early 1982. In response, Microsoft came up with a plan for tiered approach to its operating systems: single-user/single-tasking MS-DOS at the bottom; multi-user/multitasking XENIX at the top; and in the middle, something called XEDOS: a single-user version of XENIX. This "pyramid of upward-compatible operating systems" was announced in a Byte Magazine editorial in January 1982. ↫ Nemanja Trifunovic I've always found this tiered approach fascinating, and the world surely would've looked quite different had Microsoft been able to make it work. I doubt Windows NT would ever have existed, and most of the world would probably be running a XENIX-based Windows today (all else being equal, which is of course unlikely and silly). Regardless, MS-DOS 2.0 contained a few UNIX-like utilities to deal with its brand new support for directory trees and other new features, and even had a /dev directory.

If you thought pervert glasses weren't bad enough, Apple is taking it up a notch by adding cameras to its AirPods. Apple is working on camera-equipped AirPods that appear to be nearly ready to launch, based on a video MacRumors found in the macOS Tahoe 26.7 release candidate. In a short demo, a man holds a book up so the camera in the AirPods can see the title. "With Visual Intelligence, your world becomes savable. See something you like? Just ask me to save it for later," says the voiceover text. ↫ Juli Clover at MacRumors AirPods are tiny. I've seen people use them at the gym. I've seen them on playgrounds. I've seen them around swimming pools. People use them at the beach. They're used at schools. In locker rooms. Tiny cameras in tiny AirPods that can photograph anything in front of the user are a pervert's wet dream. Abusers are going to love this. Why wear bulky glasses anyone can see and try to demand you take off, when you can wear tiny AirPods that have already been fully normalised in society? Was there not a single woman or parent on the team that made this? All over the United States, people are destroying Flock surveillance cameras. More and more communities are rising up and demanding these things removed from their streets and neighbourhoods. The awareness of just how pervasive mass government surveillance has become is growing, and Silicon Valley's complicity is not exactly a secret. And in this climate of rapidly growing concern and anger, Apple is going to add tiny cameras to its tiny AirPods. Was there not a single person of colour or protester on the team that made this? How detached from reality do you have to be to greenlight something like this? Does anyone - regardless of skin colour, gender, or political leaning - want even more cameras around them?

I was around when Quake was launched, but I was entirely unaware of this story. By June 1996, after three years of hard work, id Software had completed their next title, Quake. As for their previous title, they were going to release both a shareware version and a full version of their game. Since it used a mere 22 MiB of storage, people at id Software had the idea of leveraging the remaining capacity of a CD-ROM. Why not include encrypted versions of the full id catalogue of games? Not only this would cut out the middlemen, it would give instant access to gamers with a simple phone call and a credit card. The concept was implemented. The CD was announced on July 3, 1996 and released on August 30th. The hacker group GNOMON released Quakecrk.zip only 39 days later. The archive contained QCRACK.EXE, a tool allowing to decrypt every single game on the CD-ROM. ↫ Fabien Sanglard The system id employed turned out to be incredibly primitive and simple, and hackers found out quite easily that the system required no secret sauce from id at all - the code you'd get over the phone contained no secret, and all the validation program on the disk did was check to ensure the code received over the phone matched the code generated by the disk. No wonder it took them only 39 days to crack this.

Over the last few weeks, we have been doing research on the integration of our official distribution packages when installed on a target system. In this context we have been looking at the current uses of alpm-install-scriptlet(5) files and alpm-hooks(5) in around 120 package source repositories (alpm-source-repo(7)) to better understand the underlying functionality and use-cases these two integrations offer and target. In this article we are going to look at how these two systems work, how Arch Linux is currently using them and attempt to provide suggestions for when to use which. Learning about alpm-hooks(5) and alpm-install-scriptlet(5) files …

This is just a short note on my blog that I have resigned from Arch Linux a package maintainer, developer and security team. I've spent around 10 years as an AUR maintainer, security team, Package Maintainer and then Developer. I implemented support for debug packages, did the initial POC work that would become the git migration and even somehow managed to pull of an online conference during The Plague with the help of others.
