How to Delete All of Your Social Media Accounts: Instagram, X, Facebook, TikTok, and More

Here’s an evergreen take: There has never been a better time to get off social media. Social services have evolved even further into becoming sticky traps for doomscrolling and AI-generated slop, and are hitherto unprecedented frontiers for rage bait. Bummed out about all the misinformation and being part of a profit machine that funds one increasingly unhinged billionaire or another? Well, there’s a way out. Unfortunately, social media companies don’t always make it very easy to rescind their

How to design an actually good flash flood alert system

Flash floods have wrought more havoc in the US this week, from the Northeast to the Midwest, just weeks after swollen rivers took more than 130 lives across central Texas earlier this month. Frustrations have grown in the aftermath of that catastrophe over why more wasn’t done to warn people in advance. Local officials face mounting questions over whether they sent too many or sent too few mobile phone alerts to people. Some Texans have accused the state of sending out too many alerts for injur

OpenAI, Anthropic, Google may disrupt education market with new AI tools

AI companies could soon disrupt the education market with their new AI-based learning tools for students. BleepingComputer recently reported that OpenAI is working on a Study Together feature for ChatGPT. This would allow ChatGPT to teach students a wide range of topics and then offer quizzes. The idea is to create an engaging and interactive "study together" experience where students ask questions and ChatGPT puts in effort to teach them. But it turns out that OpenAI isn't the only AI compa

Why your website should be under 14kB in size

Why your website should be under 14kB in size Why your website should be under 14kB in size Having a smaller website makes it load faster — that's not surprising. What is surprising is that a 14kB page can load much faster than a 15kB page — maybe 612ms faster — while the difference between a 15kB and a 16kB page is trivial. This is because of the TCP slow start algorithm. This article will cover what that is, how it works, and why you should care. But first we'll quickly go over some of the

Cats as Horror Movie Villains

Do people like watching cats because of neoteny? I doubt it, because adult cats don’t look at all like babies. But then why do we have this odd fascination with every ordinary action of a cat and treating them as instances of a Platonic Cat? I speculate that there may be an evolutionary psychology reason: cats in Africa prey on primates to a degree I suspect few people appreciate, and this seems to have been true for millions of years, making them our apex predator. So perhaps we are still sligh

WhatsApp streamlines in-app support process

If you’ve ever tried to get in-app support on WhatsApp, you know the process used to start with filling out a form, possibly attaching a few files, and waiting for a support rep to eventually get in touch. Now, that form is on its way out, and the screening process is, you guessed it, becoming AI-based. But that’s not necessarily a bad thing. Out with the form, in with AI Unless you’re Stephen Hackett, support knowledge bases are never fun to navigate, especially if you are in a hurry and alr

The Israeli "art student" mystery (2002)

In January 2001, the security branch of the U.S. Drug Enforcement Agency began to receive a number of peculiar reports from DEA field offices across the country. According to the reports, young Israelis claiming to be art students and offering artwork for sale had been attempting to penetrate DEA offices for over a year. The Israelis had also attempted to penetrate the offices of other law enforcement and Department of Defense agencies. Strangest of all, the “students” had visited the homes of n

Netflix’s first show with generative AI is a sign of what’s to come in TV, film

Netflix used generative AI in an original, scripted series that debuted this year, it revealed this week. Producers used the technology to create a scene in which a building collapses, hinting at the growing use of generative AI in entertainment. During a call with investors yesterday, Netflix co-CEO Ted Sarandos revealed that Netflix's Argentine show The Eternaut, which premiered in April, is "the very first GenAI final footage to appear on screen in a Netflix, Inc. original series or film.” S

Anthropic tightens usage limits for Claude Code — without telling users

Since Monday morning, Claude Code users have been hit with unexpectedly restrictive usage limits. The problems, many of which have been aired on Claude Code’s GitHub page, seem to be concentrated among heavy users of the service, many of whom are on the $200-a-month Max plan. Users are only told “Claude usage limit reached,” and given a time (typically within a matter of hours) when the limit will reset. But with no explicit announcement of a change in limits, many users have concluded that the

Scientists prove Android Earthquake Alerts system actually works pretty well

Google TL;DR Google’s Android Earthquake Alerts system crowdsources data from smartphone accelerometers to detect seismic activity. The system has detected over 18,000 earthquakes and alerted millions across nearly 100 countries. Users receive crucial seconds of warning, enabling them to take protective action before shaking begins. Google introduced Earthquake Alerts for Android devices back in 2020, and expanded the feature to cover all US states in September 2024. More recently, Google al

WhatsApp should prepare to stop operating in Russia, official says

A Russian lawmaker who regulates the IT industry said WhatsApp should prepare to stop offering its services in the country. Anton Gorelkin, the deputy head of the lower house of parliament's IT committee, said that it's very likely that WhatsApp will be placed on a list of restricted software, as Reuters reports. WhatsApp owner Meta is designated as an extremist organisation in Russia, which has banned Facebook and Instagram since 2022. This week, President Vladimir Putin issued a directive for

Psilocybin decreases depression and anxiety in cancer patients (2016)

Nintendo launches another Switch Online test program for 40,000 players

Nintendo has posted a call for participants for another Playtest Program, and this time, it's looking for 40,000 testers and not just 10,000 like in the first one. If you'll recall, Nintendo looked for 10,000 participants for the first Playtest event last year to test an unnamed, mysterious Switch Online feature. The new program still only welcomes active Nintendo Switch Online + Expansion Pack members, but as you'd expect, it now supports both the original Switch and the Switch 2. Interested p

The Download: three-person babies, and tracking “AI readiness” in the US

Eight babies have been born in the UK thanks to a technology that uses DNA from three people: the two biological parents plus a third person who supplies healthy mitochondrial DNA. The babies were born to mothers who carry genes for mitochondrial diseases and risked passing on severe disorders. In the team’s approach, patients’ eggs are fertilized with sperm, and the DNA-containing nuclei of those cells are transferred into donated fertilized eggs that have had their own nuclei removed. The new

Citrix Bleed 2 exploited weeks before PoCs as Citrix denied attacks

A critical Citrix NetScaler vulnerability, tracked as CVE-2025-5777 and dubbed "CitrixBleed 2," was actively exploited nearly two weeks before proof-of-concept (PoC) exploits were made public, despite Citrix stating that there was no evidence of attacks.

Mammals Evolved into Ant Eaters 12 Times Since Dinosaur Age, Study Finds

Written by: Jesse Jenkins Published: A first-of-its-kind study traces the rise of ant- and termite-eaters, revealing how mammals returned to the evolutionary table — at least a dozen times — to hone traits for feasting on the social insect bonanza that exploded after the extinction of the dinosaurs. Mammals have developed some unusual eating habits over the past 100 million years, but a new study has uncovered the surprising lengths some have gone to satisfy one of the more peculiar — a taste

The Big EV Tax Credit Mystery

If you’re thinking about buying an electric vehicle, brace yourself: the federal tax credits that offer up to $7,500 off new EVs and $4,000 off used ones could change as soon as September 30. But here’s the real issue: Nobody knows for sure what happens next. Carmakers, consumers, and even some dealerships have been operating under the belief that a signed contract before September 30 locks in the credit. But now, some automakers are quietly admitting that the IRS has not finalized that rule.

AI-Powered Smart Devices Help Older Adults Age at Home, Survey Finds

Older adults often find artificial intelligence smart home devices and voice assistants useful in helping them age in place, according to a new survey by the University of Michigan. More than half of people surveyed aged 50 and older have used generative AI tools they spoke or typed messages to, according to the National Poll on Healthy Aging, released by the U-M Institute for Healthcare Policy and Innovation. By comparison, a June Pew Research Center poll found that 25% of US adults 50 to 64
