Meta-analysis of three different notions of software complexity

A meta-analysis of three different notions of software complexity I want to discuss three different notions of software complexity: Rich Hickey’s notion of complexity, as explained in his talk Simple Made Easy. John Ousterhout’s notion of complexity, as explained in his book A Philosophy of Software Design. Zach Tellman’s notion of complexity, as explained in his newsletter Explaining Software Design. I’ve picked these three because I’ve found them to be at least somewhat coherent, and the

The Space Station Leak Is Rearing Its Ugly Head Again

Space Draft Space tourism company Axiom Space has had to postpone its fourth chartered SpaceX flight to the International Space Station after NASA announced it needs more time to investigate an air leak affecting the orbital lab. For five years, NASA and its Russian counterpart Roscosmos have been hunting down leaks in the station, which has been continuously occupied for 25 years. The issue has since been traced back to the Russian segment of the ISS, specifically the Zvezda service module, a

Whatever Happened to Sandboxfs?

Back in 2017–2020, while I was on the Blaze team at Google, I took on a 20% project that turned into a bit of an obsession: sandboxfs. Born out of my work supporting iOS development, it was my attempt to solve a persistent pain point that frustrated both internal teams and external users alike: Bazel’s poor sandboxing performance on macOS. sandboxfs was a user-space file system designed to efficiently create virtual file hierarchies backed by real files—a faster alternative to the “symlink fore

Paid proxy servers vs free proxies: Is paying for a proxy service worth it?

marian / Getty Images Proxy servers are the middlemen of cyberspace. Acting as gateways between our devices and the Internet, proxy servers are used by businesses and individuals worldwide for a variety of tasks. While proxy servers were once almost exclusively used by companies to redistribute traffic and load or for caching purposes, they now offer a degree of online anonymity for individuals. Requests you make are first sent to the proxy and then forwarded -- and this process assigns you a

100 years of Zermelo's axiom of choice: What was the problem with it? (2006)

100 years of Zermelo’s axiom of choice: What was the problem with it? Per Martin-Löf 2006 WORK IN PROGRESS Cantor conceived set theory in a sequence of six papers published in the Mathematische Annalen during the five year period 1879–1884. In the fifth of these papers, published in 1883, he stated as a law of thought (Denkgesetz) that every set can be well-ordered or, more precisely, that it is always possible to bring any well-defined set into the form of a well-ordered set. Now to call it

9 Best 2-in-1 Laptops (2025), Tested and Reviewed

A 2-in-1 is a laptop that can go from a standard clamshell laptop configuration to a tablet setup. Over the years, there are really two types of designs that fall into this category: the convertible 2-in-1 laptop and the detachable tablet. Laptops with rotating displays—also called convertibles—use a 360-degree hinge that can position the screen flat, in “tent” mode, or flush against the underside of the laptop. Think of this as a touchscreen clamshell laptop with a fancy hinge. The flexibility

Tesla's Robotaxi Launch Date Was Supposed to Be Today, But We're Shocked to Hear That It's Been Pushed Back

The launch of Tesla's robotaxi network will have to wait. On Tuesday, CEO Elon Musk made a tweet stating that, "tentatively," the first public rides on its autonomous vehicles — which will not be in its purpose-built Cybercabs, but in regular Teslas with updated software — will start on June 22. But the date could shift, Musk added, because "we are being super paranoid about safety." That comment could prove to be revealing. Tesla's robotaxi initiative is clouded with uncertainty, because th

Instagram May Soon Let You Rearrange Your Grid. What to Know

If you like to keep your Instagram profile as more of a personal photo album and less of a public bulletin board, Instagram's upcoming feature is for you. Instagram will let users quietly post to your profile without broadcasting it to your followers, the company said on Thursday. Instagram also said it would let you rearrange your profile grid. It's not clear how either feature will work yet. Static posts and Reels have historically appeared in chronological order on Instagram, so this could o

Public gains unprecedented access to Webb telescope's vast cosmic survey

The big picture: A new chapter in cosmic exploration has begun with the release of a vast, searchable database from the COSMOS-Web survey, granting the public unprecedented access to the deepest view of the universe ever captured by the James Webb Space Telescope. This milestone allows everyone from seasoned astronomers to curious enthusiasts to explore and analyze a treasure trove of celestial data that was once the exclusive domain of specialized researchers. The COSMOS-Web project – the larg

Tesla's long-awaited robotaxi service is coming to Austin this month

Something to look forward to: Robotaxi services are widely seen as the next major breakthrough in transportation, with Alphabet-owned Waymo already expanding its self-driving taxi operations across several US cities. Now, Elon Musk has announced that Tesla is finally ready to launch its long-awaited autonomous cab service in Austin, Texas, later this month. Replying to an X user asking about when public rides would begin, Musk said the launch date is "tentatively" set for June 22, but the actua

You Are Completely Unprepared for What Tesla's Robotaxi Actually Looks Like

We've finally gotten a glimpse at one of Tesla's Robotaxis in action. But don't expect your socks to be blown off. As seen in a bystander's footage taken in Austin, Texas, that Elon Musk has proudly reshared, it's literally just a black Model Y with the word "Robotaxi" scrawled on the side in a painfully outdated graffiti font. The future is truly upon us. "Beautifully simple design," Musk tweeted, presumably through a pained grimace. BREAKING: First ever Tesla Model Y robotaxi with no-one in

The impossible is happening: An Android phone will be compatible with Apple Watch

Dhruv Bhutani / Android Authority TL;DR Vivo has started teasing its next foldable, the X Fold 5. A product manager confirms that the Android phone will have Apple Watch compatibility. It’s also said to have direct support for iCloud and can be used as an extended screen with a Mac. At one point, Apple reportedly considered making an Apple Watch that’s compatible with Android to help it reach the platform’s billions of users. However, those plans eventually fell through and Apple has continu

Tesla will start offering public Robotaxi rides in Austin on June 22, says Elon Musk

Tesla CEO Elon Musk says that Robotaxi service is "tentatively" set to begin in Austin, Texas on June 22. This comes after the company said last month that it had already begun testing driverless Model Ys in Austin. Shortly after that, Bloomberg reported that Tesla had internally discussed a launch date of June 12, though the only publicly shared timeline has been sometime in June . The first Robotaxi Model Y operating without a person in the driver's seat was spotted on South Congress in Austi

Apple to add proximity pairing setup to the Mac with macOS 15.4

iPhone and iPad users are already very familiar with something called “proximity pairing.” First introduced with iOS 11, this feature lets users transfer backup and other data from one device to a new one just by placing them close together. Now it seems that Apple is finally working on adding proximity pairing setup to the Mac. Proximity pairing setup coming to the Mac Evidence seen by 9to5Mac in the iOS 18.4 code suggests that the Mac will soon gain proximity pairing, just like the iPhone an

Mexico issues legal threat to Google

John David Mercer-USA TODAY Sports On Jan. 20, United States President Donald Trump signed an executive order renaming the “Gulf of Mexico” to “Gulf of America.” Last week, Google Maps officially changed the name of the gulf on its maps, sparking a flurry of memes and conversation on social media, and Mexico is now threatening legal action if they don’t change it back. In a press conference on Monday, Mexican President Claudia Sheinbaum said that Mexico will sue Google if the company does not
