How to download your information from Facebook

Once upon a time Facebook was filled with posts about the minutiae of your day and album after album of photos of just about every experience you had. By now, a lot of this media is likely hidden with the "only me" setting. But, regardless of how much you use Facebook these days, it's probably home to a lot of memories you want to hold on to — or at least have the opportunity to laugh at later. The good news is that you can download your Facebook information. You can access things such as your

Solving LinkedIn Queens with APL

Solving LinkedIn Queens with APL 14 Jun 2025 on Peter Vernigorov’s blog A couple months ago I noticed that LinkedIn now has a few simple games. They’re not much to write home about, but I really enjoy playing Queens. This week I saw two posts about solving the Queens game programmatically. Both were quite interesting to me, so I thought this was a good opportunity to also solve the game in my favourite language - APL - and share my experience. Having been using APL for Advent of Code, I wante

Is Gravity Just Entropy Rising? Long-Shot Idea Gets Another Look

Isaac Newton was never entirely happy with his law of universal gravitation. For decades after publishing it in 1687, he sought to understand how, exactly, two objects were able to pull on each other from afar. He and others came up with several mechanical models, in which gravity was not a pull, but a push. For example, space might be filled with unseen particles that bombard the objects on all sides. The object on the left absorbs the particles coming from the left, the one on the right absorb

How to set up a WhatsApp account without Facebook or Instagram

There's no shortage of reasons to stay off the Meta ecosystem, which includes Facebook and Instagram, but there are some places where WhatsApp remains the main form of text-based communication. The app is a great alternative to SMS, since it offers end-to-end encryption and was one of the go-to methods to send uncompressed photos and videos between iPhone and Android users before Apple adopted RCS. Even though Facebook, which later rebranded to Meta, acquired WhatsApp in 2014, it doesn't require

Companies may soon pay a fee for their rockets to share the skies with airplanes

The Federal Aviation Administration may soon levy fees on companies seeking launch and reentry licenses, a new tack in the push to give the agency the resources it needs to keep up with the rapidly growing commercial space industry. The text of a budget reconciliation bill released by Sen. Ted Cruz (R-Texas) last week calls for the FAA's Office of Commercial Space Transportation, known as AST, to begin charging licensing fees to space companies next year. The fees would phase in over eight year

The Mysterious Inner Workings of Io, Jupiter’s Volcanic Moon

The original version of this story appeared in Quanta Magazine. Scott Bolton’s first encounter with Io took place in the summer of 1980, right after he graduated from college and started a job at NASA. The Voyager 1 spacecraft had flown past this moon of Jupiter, catching the first glimpse of active volcanism on a world other than Earth. Umbrella-shaped outbursts of magmatic matter rocketed into space from all over Io’s surface. “They looked amazingly beautiful,” said Bolton, who is now based a

CI/CD Observability with OpenTelemetry Step by Step Guide

In the fast-paced world of CI/CD, understanding the performance and behaviour of your pipelines is crucial. GitHub Actions has become a popular choice for automating builds and deployments, but anyone who's debugged a flaky workflow or long-running job knows how challenging it can be to get visibility into what's happening under the hood. We usually rely on build logs, timing data, or guesswork when something goes wrong. Wouldn't it be nice to trace a pipeline run step-by-step, or have metrics o

Peeling the Covers Off Germany's Exascale "Jupiter" Supercomputer

The newest of the exascale-class supercomputer to be profiled in the Top500 rankings in the June list is the long-awaited “Jupiter” system at Forschungszentrum Jülich facility in Germany. We finally have a sense of how this hybrid CPU-GPU machine will perform, although some of the details on its configuration are still not nailed down publicly. Jupiter is the first exascale system to be completed under the EuroHPC Joint Undertaking of the European Union, and the fact that it is not using a cust

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

Shaping Light – Volumetric Lighting

As I became more familiar with post-processing over the past few months, I was curious to push those newly learned techniques beyond pure stylization to achieve something more functional. I wanted to find new ways to enrich my 3D work which wouldn't be possible without leveraging effects and passes alongside custom shaders. As it turns out, post-processing is great entrypoint to enhance a 3D scene with atmospheric and lighting effects, allowing for more realistic and dramatic visuals. Because t

Mel Brooks returns from the retirement home to save a galaxy 'very, very, very, very, far away'

Editor's take: If you're around my age, chances are you grew up loving at least one Mel Brooks classic. Young Frankenstein was my personal favorite, and Spaceballs cracked me up with its irreverent jabs at Star Wars and other sci-fi hits of the era. Now, nearly four decades later, Brooks is back with a sequel. After nearly 40 years, Mel Brooks is finally making a follow-up to his classic Star Wars spoof, Spaceballs. The nonagenarian announced the project with a hilarious clip parodying the open

Embracer CEO Lars Wingefors will step down as CEO; deputy Phil Rogers will take his place

Embracer CEO Lars Wingefors is stepping down as CEO while his deputy CEO Phil Rogers will take over the top job in August. Wingefors spun his Swedish game holding company out of Nordic Games Group in 2016, and he renamed it Embracer Group in 2019. Wingefors was a controversial leader in the game industry, as he built up Embracer Group to more than 100 game studios, only to fall victim in the post-pandemic slowdown. As growth slowed, Wingefors had to lay off a lot of people, sell off studios or

Inside the firm turning eerie blank streaming ads into useful nonprofit messages

StreamTV Insider provided flights from New York City to Denver and two nights of accommodation so Ars could attend its StreamTV Show. Ars does not accept paid editorial content. DENVER—Ads shown while you're streaming shows or movies are disruptive enough. But there's something uniquely eerie about what you see when a connected TV (CTV) platform fails to sell ad inventory.

There’s another leak on the ISS, but NASA is not saying much about it

There's another leak on the International Space Station, and NASA has already delayed one crew launch to the orbiting laboratory as a result. Beyond that, the space agency is not offering much information about the unfolding situation in orbit. However, multiple sources have confirmed to Ars that the leak is a serious concern for the space agency as it deals with hardware that is approaching three decades in orbit. To understand the current situation, it is important to review past leaks on th

Rocket Report: New delay for Europe’s reusable rocket; SpaceX moves in at SLC-37

Welcome to Edition 7.48 of the Rocket Report! The shock of last week's public spat between President Donald Trump and SpaceX founder Elon Musk has worn off, and Musk expressed regret for some of his comments going after Trump on social media. Musk also backtracked from his threat to begin decommissioning the Dragon spacecraft, currently the only way for the US government to send people to the International Space Station. Nevertheless, there are many people who think Musk's attachment to Trump co

This post briefly describes jemalloc’s development phases, each with some success/failure highlights, followed by some retrospective commentary. Phase 0: Lyken In 2004 I began work on the Ly

NBA Finals 2025: When Is Game 4 and How to Watch Without Cable

It's a quick turnaround for game 4 of the NBA Finals. Instead of the regular cadence of two days between games, there's only one off-night before the Indiana Pacers and Oklahoma City Thunder are back on the court for game 4. After splitting the first two games in Oklahoma City, the Pacers defeated the Thunder last night in front of a raucous home crowd in game 3 to take a 2-1 series lead.

Google warns Wear OS users to install their favorite legacy watch faces before 2026

After Google introduced Watch Face Format (WFF) in 2023, WFF and non-WFF watch faces coexisted. This only lasted for a short time, however, as Google eventually made WFF mandatory. Since then, the company has been gradually phasing out support for non-WFF watch faces on Wear OS . Google has now announced the next step it will take to get to full adoption of WFF. If you’re a Wear OS user who cares about custom watch faces, then you may know that support for AndroidX and Wearable Support Library

There's a Giant Problem With SpaceX's Starlink Satellites

Astronomers' attempts to peer into the earliest reaches of the universe could be threatened by thousands of SpaceX Starlink satellites leaking radio emissions that ruin observations made with highly sensitive telescopes. As New Scientist reports, a team of researchers led by Curtin University radio astronomy professor Steven Tingay tracked the signals of almost 2,000 Starlink satellites, with the help of a prototype telescope from the Square Kilometre Array, which is currently under constructio

‘Andor’ Wanted Its Massacre to Do More Than Just Fill a ‘Star Wars’ Lore Gap

The most impactful thing about the Ghorman Massacre in Andor season two is how it paints a true picture of what rebellion stood for by putting the audience in the shoes of the people assembled to defend their planet. In a grim yet hopeful episode, the Empire’s control of the narrative begins to fall apart, showcasing the brutal violence meted out by Imperial forces against those who resist Palpatine’s rule. Series creator Tony Gilroy and star Diego Luna gave more context about expounding on a k

How to Protest Safely in the Age of Surveillance

If you insist on using biometric unlocking methods to have faster access to your devices, keep in mind that some phones have an emergency function to disable these types of locks. Hold the wake button and one of the volume buttons simultaneously on an iPhone, for instance, and it will lock itself and require a passcode to unlock rather than FaceID or TouchID, even if they’re enabled. Most devices also let you take photos or record video without unlocking them first, a good way to keep your phone
