Scientists Detect Strange Signal in Gravitational Waves

futurism.com Unknown 2025-09-19 04:06:23

For the first time, astrophysicists have measured the recoil — or "kick," in the parlance — resulting from the birth of a new black hole that formed from the merger of two preexisting ones. The international team of researchers measured the ripples in the fabric of spacetime, known as gravitational waves, allowing them to get unprecedented insights into the turbulent dynamics of two black holes crashing into each other. The team analyzed data collected by the Advanced LIGO and Virgo gravitatio

I just want an 80×25 console, but that's no longer possible

news.ycombinator.com John Goerzen 2025-09-20 12:26:02

Somehow along the way, a feature that I’ve had across DOS, OS/2, FreeBSD, and Linux — and has been present on PCs for more than 40 years — is gone. That feature, of course, is the 80×25 text console. Linux has, for awhile now, rendered its text console using graphic modes. You can read all about it here. This has been necessary because only PCs really had the 80×25 text mode (Raspberry Pis, for instance, never did), and even they don’t have it when booted with UEFI. I’ve lately been annoyed t

Pulling an Inverse Conway Maneuver at Netflix (2023)

Pulling an Inverse Conway Maneuver at Netflix When I first joined the Netflix Platform team circa 2020, the Observability offering was composed of a series of tools serving different purposes. There was Atlas for metrics, Edgar for distributed tracing, Radar for Logs and Alerts, Lumen for dashboards, Telltale for app health, etc. It was a portfolio of about 20 different apps. Big and small, ranging from business-specific tools to analyze playback sessions to low-level tools for CPU profiling.

How eSIMs Work, and How to Switch to One From a Standard SIM

wired.com David Nield 2025-10-01 22:00:00

The physical SIM cards we've used for decades are slowly being phased out. With the Pixel 10 series, Google's phones have gone eSIM-only for the first time—at least if you buy them in the US. Apple made the same move with the iPhone 14 in 2022, and now its new iPhone 17 models will operate with eSIMs in a dozen countries, with the slim iPhone Air going eSIM-only everywhere in the world. But how is eSIM different, and what do you need to do to switch? The good news is that by most measures, eSI

Why you’ll want to have two tabs open to watch the iPhone 17 event

ChatGPT’s new branching feature is a good reminder that AI chatbots aren’t people

On Thursday, OpenAI announced that ChatGPT users can now branch conversations into multiple parallel threads, serving as a useful reminder that AI chatbots aren't people with fixed viewpoints but rather malleable tools you can rewind and redirect. The company released the feature for all logged-in web users following years of user requests for the capability.

Experts will give you an array of opinions, depending on their area of specialization or what thesis paper they’re writing. There is no single right answer. Political squabbling, weakened borders, a diluted army, disease, economic crises... some even say it was because of lead in the pipes.

Deeply divided Supreme Court lets NIH grant terminations continue

These terminations were challenged in court, and a consolidate case was heard in the District of Massachusetts, pitting the government against individual researchers, organizations that represent them, and states that host research institutions.

But what a new piece argues for is not to replace the existing Apple Watch design, but instead to offer us a greater range of options … It’s not coincidence that Apple chose a rectangular display for the Apple Watch.

Why MIT switched from Scheme to Python (2009)

Costanza asked Sussman why MIT had switched away from Scheme for their introductory programming course, 6.001. This was a gem. He said that the reason that happened was because engineering in 1980 was not what it was in the mid-90s or in 2000. In 1980, good programmers spent a lot of time thinking, and then produced spare code that they thought should work. Code ran close to the metal, even Scheme — it was understandable all the way down.
