When SpaceX deploy batches of Starlink satellites they drop them off in lower orbits and expect the satellites themselves to navigate towards their final operational orbits. This is quite a complex process and one that's worth discussing, the satellites need to be able to reach the target orbital…

The Gotthard Base Tunnel in Switzerland is 57km long: and I think its greatest piece of safety equipment is nowhere near the tunnel itself. ■ Thanks to Swiss Federal Railways https://www.sbb.ch/ - drone filming near the tracks was specially approved with railway staff. ■ For tours into the Gotthard…

After a long drive, the only thing that makes our stomachs churn faster than a windshield smeared with bug guts is a windshield bearing no evidence of insect life whatsoever. It feels like a fundament

Mike Conner sits in his truck atop a hill in Boring, Oregon, where he can feel the summer breeze through the window and see the sun at its meridian over the fields and the snowcapped tip of a distant Mount Hood poking into a cloud-dotted sky. He sits here and thinks about cutting off his feet. His…

Photo cred: my dad Two truths (no lies): 1. Once you are moderately happy, it’s very hard to get any happier. 2. Everybody secretly believes they can be the exception to this rule. Psychologists have known for fifty years that people tend to adjust to the good things that happen to them, ending up…

The best theory physicists have for the birth of the universe makes no sense. It goes like this: In the beginning—the very, if not quite veriest, beginning—there’s something called quantum foam. It’s barely there, and can’t even be said to occupy space, because there’s no such thing as space yet. Or…

Goose Maps 10 min read· Sep 25, 2022 -- TL;DR Recently we’ve launched an offline maps application for Apple Watch. This project has taken more than two years and the full attention of our small team of enthusiasts. We’ve faced so many product and technical issues along the way that we simply need to…

Elon Musk, in a tweet (of course): Buying Twitter is an accelerant to creating X, the everything app. Kara Swisher explains: He is essentially talking about a “super app,” which is common in China but not the U.S. and might include payments, subscriptions, entertainment etc. It’s the right idea but…

Als Manuel C. Widmer nach den Herbst­ferien 2019 ins Berner Schulhaus Tscharnergut zurückkehrte, lief überhaupt nichts mehr so, wie es sollte. «Man konnte nicht drucken, Daten gingen verloren, die neuen Tablets konnten nur teilweise benutzt werden, und schliesslich stotterte auch noch das Internet»,…

Stellen Sie sich vor, ein Mann zieht ein T-Shirt von Osama bin Laden an und provoziert damit an einer Trauer­feier für Opfer eines islamistischen Terror­anschlags. Oder mit einem T-Shirt des Islamischen Staats vor einer Kirche oder einer Synagoge. Und als der Mann irgendwann angegangen und…

Rachel Gerberding has a green thumb. So when her mother died this April, Gerberding decided to compost her. Gerberding, who lives in Washington state in a house surrounded by flowers, had heard about a newly legal method to turn human remains into soil. “I was like, ‘Mom, it would be such a…

Ever since the U.S. Senate failed to convict Donald Trump for his role in the January 6 insurrection and disqualify him from running for president again, a lot of people, myself included, have been warning that a second Trump term could bring about the extinction of American democracy. Essential…

Unfassbar, aber wahr: Auch in Deutschland kommt die Digitalisierung an. Mittlerweile sogar in Arztpraxen. Termine buchen, Akten durchsuchen, Krankschreibungen und Abrechnungen ausstellen – das alles kann mit einer Software erledigt werden. Die kennt dann Praxen und Patient*innen sehr gut – sehr,…

Aerodynamics are an important factor in gravel racing and riding. Gravel racing speeds are high—the fastest riders in the 200-mile Unbound average 20 mph (32 km/h) across the Flint Hills of Kansas. And many gravel races can be extremely windy. Optimizing the aerodynamics of a gravel bike is…

The blank screen was already intimidating enough. Then, out of nowhere, an incorporeal know-it-all popped up to make us feel even worse about the novel notion of word processing in the mid-’90s. “It looks like you’re writing a letter,” a googly-eyed, caterpillar-browed paperclip in Microsoft Word…

A love letter to tools that changed everything for me. Programming over the years Programming got vastly more varied compared to when I started dabbling in AmigaBASIC in the mid-1990s. Back then you could buy one very big book about the computer you’re programming and were 99% there. That book, full…

2022-09-15 part 1 | part 2 | you are here | part 4 I said up front that the NNSS remains in use for several different purposes, although the level of activity today is not nearly as high as it once was. To my best ability to remember the numbers, I think we were told that during the period of active…

2022-09-11 you are here | part 2 | part 3 | part 4 I promised a travelogue, and here we go. I'm not exactly a travel writer, but I was recently able to visit a place that's fairly difficult to get to, so I think it's worth sharing my observations. I started writing this because I thought there…

Back in 2020, my school used a few online learning platforms that allowed professors/teachers to assign homework to students. I, as a lazy developer, wanted to spend more time playing games and writing code, especially when everyone was spending their time at home because of lockdown. I started…

Unless you have skipped a lot of school, or work, or both – or you live in the USA – you have probably used an A4 sheet of paper before now. Have you ever wondered why it is the shape or size it is? Time to dust off some high-school level maths to investigate. Just in case you have never actually…

Share An array of supercomputers crunching the fiendishly complex windtunnel data of 121 terracotta cyclists has revealed that a rider in the sweet-spot of a peloton experiences up to ten times less air resistance than previously assumed. It’s long been known that an average person on a bicycle is a…
