Startup Wants To Launch a Space Mirror

1 day ago
A startup called Reflect Orbital wants to launch thousands of mirror-bearing satellites to reflect sunlight onto Earth at night and "power solar farms after sunset, provide lighting for rescue workers and illuminate city streets, among other things," reports the New York Times. From the report: It is an idea seemingly out of a sci-fi movie, but the company, Reflect Orbital of Hawthorne, Calif., could soon receive permission to launch its first prototype satellite with a 60-foot-wide mirror. The company has applied to the Federal Communications Commission, which issues the licenses needed to deploy satellites. If the F.C.C. approves, the test satellite could get a ride into orbit as soon as this summer. The F.C.C.'s public comment period on the application closes on Monday. "We're trying to build something that could replace fossil fuels and really power everything," Ben Nowack, Reflect Orbital's chief executive, said in an interview. The company has raised more than $28 million from investors. [...] Reflect Orbital's first prototype, which will be roughly the size of a dorm fridge, is almost complete. Once in space, about 400 miles up, the test satellite would unfurl a square mirror nearly 60 feet wide. That would bounce sunlight to illuminate a circular patch about three miles wide on the Earth's surface. Someone looking up would see a dot in the sky about as bright as a full moon. Two more prototypes could follow within a year. By the end of 2028, Reflect Orbital hopes to launch 1,000 larger satellites, and 5,000 of them by 2030. The largest mirrors are planned to be nearly 180 feet wide, reflecting as much light as 100 full moons. The company said its goal was to deploy the full constellation of 50,000 satellites by 2035. How much does it cost to order sunlight at night? Mr. Nowack said the company would charge about $5,000 an hour for the light of one mirror if a customer signed an annual contract for 1,000 hours or more. Lighting for one-time events and emergencies, which might require numerous satellites and more effort to coordinate, would be more expensive. For solar farms, he envisions splitting revenue from the electricity generated by the additional hours of light.

CodeSOD: To Shutdown You Must First Shutdown

1 day 1 hour ago

Every once in awhile, we get a bit of terrible code, and our submitter also shares, "this isn't called anywhere," which is good, but also bad. Ernesto sends us a function which is called in only one place:

/// /// Shutdown server /// private void shutdownServer() { shutdownServer(); }

The "one place", obviously, is within itself. This is the Google Search definition of recursion, where each recursive call is just the original call, over and over again.

This is part of a C# service, and this method shuts down the server, presumably by triggering a stack overflow. Unless C# has added tail calls, anyway.

SETI admits its search for alien life may be too narrowly focussed

1 day 2 hours ago
Solar winds near aliens’ homes – and ours – might be blowing away signs of alien technosignatures by broadening signals

The SETI Institute, the nonprofit that conducts a search for extraterrestrial intelligence by examining radio waves for artefacts that are unlikely to be the result of natural processes, thinks it may have been going about it the wrong way.…

European Consortium Wants Open-Source Alternative To Google Play Integrity

1 day 4 hours ago
An anonymous reader quotes a report from Heise: Pay securely with an Android smartphone, completely without Google services: This is the plan being developed by the newly founded industry consortium led by the German Volla Systeme GmbH. It is an open-source alternative to Google Play Integrity. This proprietary interface decides on Android smartphones with Google Play services whether banking, government, or wallet apps are allowed to run on a smartphone. Obstacles and tips for paying with an Android smartphone without official Google services have been highlighted by c't in a comprehensive article. The European industry consortium now wants to address some problems mentioned. To this end, the group, which includes Murena, which develops the hardened custom ROM /e/OS, Iode from France, and Apostrophy (Dot) from Switzerland, in addition to Volla, is developing a so-called "UnifiedAttestation" for Google-free mobile operating systems, primarily based on the Android Open-Source Project (AOSP). According to Volla, a European manufacturer and a leading manufacturer from Asia, as well as European foundations such as the German UBports Foundation, have also expressed interest in supporting it. Furthermore, developers and publishers of government apps from Scandinavia are examining the use of the new procedure as "first movers." In its announcement, Volla explains that Google provides app developers with an interface called Play Integrity, which checks whether an app is running on a device with specific security requirements. This primarily affects applications from "sensitive areas such as identity verification, banking, or digital wallets -- including apps from governments and public administrations". The company criticizes that the certification is exclusively offered for Google's own proprietary "Stock Android" but not for Android versions without Google services, such as /e/OS or similar custom ROMs. "Since this is closely intertwined with Google services and Google data centers, a structural dependency arises -- and for alternative operating systems, a de facto exclusion criterion," the company states. From the consortium's perspective, this also leads to a "security paradox," because "the check of trustworthiness is carried out by precisely that entity whose ecosystem is to be avoided at the same time". The UnifiedAttestation system is built around three main components: an "operating system service" that apps can call to check whether the device's OS meets required security standards, a decentralized validation service that verifies the OS certificate on a device without relying on a single central authority, and an open test suite used to evaluate and certify that a particular operating system works securely on a specific device model. "We don't want to centralize trust, but organize it transparently and publicly verifiable. When companies check competitors' products, we can strengthen that trust," says Dr. Jorg Wurzer, CEO of Volla Systeme GmbH and initiator of the consortium. The goal is to increase digital sovereignty and break free from the control of any one, single U.S. company, he says.
