X Will Start Selling ‘Inactive’ Usernames Soon

If you haven’t logged into X for a while but still want to keep your X username, you might want to log back in soon. According to a recent post on the website formerly known as Twitter, the company will soon start selling “handles that are no longer in use” to paying subscribers.

The feature, called the X Handle Marketplace, is currently only being teased, but a waitlist for it is live. Once active, it’ll allow X Premium+ subscribers (at the $40/month level) and Premium Business accounts to both request free (with their subscription, at least) handles, and directly purchase especially rare ones.

Rare usernames could cost $2,500 or more

According to an FAQ page, pricing for rare handles starts at $2,500 and could go “over seven figures, depending on demand and uniqueness.” You’ll also need an invitation to even be allowed to purchase a paid username, although receiving the complimentary handles also comes with complications.

For free handles, there are two types. The standard ones, called “priority handles,” are open for any eligible subscriber to request; X says it will usually review requests within three business days, although not all requests will be approved. But X also says it will occasionally drop select rare handles (the type it would usually charge for) as part of free giveaways, where multiple subscribers can apply for the handle and a winner will be selected “based on merit.”

As for what X considers “merit” to be, that would include past contributions to the site, intended usage for the handle, as well as engagement and reach on the platform.

Once you’ve got a new handle, your current username will be locked so others won’t be able to change it, and your page’s @ will change to the new one. X also says it may offer paid redirects from old usernames to new ones in the future.

Note, though, that if you got your new handle for free, you’ll need to stay subscribed to keep using it. Users who paid for their handles will be able to let their X subscriptions lapse without losing them.

What handles X will be giving out for free

As for what type of inactivate handles X will be giving out, the site has provided a few examples. Generally, paid handles will be pithy, one word, “culturally significant names,” like @Pizza or @Tom. Meanwhile, free ones are more likely to be full names or multi-word phrases, like @GabrielJones or @PizzaEater. 

As someone who doesn’t subscribe to X, it’s the full names that have me concerned—and the ones I’d suggest logging into your account to preserve. Part of the reason I haven’t deactivated my X account yet is because I don’t want someone else to be able to make an account with my username, which is a variation on my full given name. I don’t post on it very often, but I’d rather others not be able to easily masquerade as me.

With that in mind, I’ve reached out to X to ask how the website will decide when to make “inactive” usernames available to request, and will update this post when I hear back. X’s inactive account policy says that users should log in “at least every 30 days” to keep their accounts active, though, so if you’re concerned about your username being taken, it’s best to play it safe.

To be fair to X, redistributing usernames from inactive accounts is not an unheard of practice for social media sites, although charging for them is a bit novel. X says the reason it’s requiring a subscription to access the X Handle Marketplace is “to prevent bot spam or misuse,” so that the site can make way for “fair and secure distribution through a controlled process.”

However, as hinted at by another change coming to the site, a subscribed account does not necessarily mean a bot-free account. I’m curious to see how the X Handle Marketplace launch goes once the feature hits the (paying) public.

“FTP Check” Challenge Launched

Today, Zwift launched a new “FTP Check” mini-challenge, with the goal of encouraging Zwifters to test their FTP in a uniquely Zwifty way so training metrics are accurate as we head into indoor season.

Challenge Requirements

The Challenge has two parts, which are meant to be completed in the same session:

  1. Ride the Ultimate Warmup
  2. Complete the Oh Hill No route, going full gas on The Grade KOM as an FTP test.

About “The Grade”

While Zwift now looks at all activities and will alert you to an FTP increase if it detects on, The Grade KOM is particularly designed as an FTP test. When you finish the KOM segment, the game looks at your average power on the segment, as well as your segment time, then computes an FTP estimate, displaying it on the sign as you ride through the KOM arch:

Read my review of riding “The Grade” FTP test >

If you’ve never ridden The Grade before, it’s helpful to have an estimate of how long it will take so you can pace yourself accordingly. Here are segment times from our bot tests with a 75kg, 183cm rider on the Tron bike at various power levels:

  • 150W (2 W/kg): 27:46
  • 225W (3 W/kg): 18:47
  • 300W (4 W/kg): 14:22
  • 375W (5 W/kg): 11:44
  • 450W (6 W/kg): 10:04

Challenge Rewards

Your reward for completing both parts of the challenge is 500 bonus XP, so you can level up faster.

Experts Hail ‘Remarkable’ Success of Electronic Implant in Restoring Sight

An electronic eye implant has restored reading ability to patients blinded by geographic atrophy, a form of dry age-related macular degeneration. Results published Monday in the New England Journal of Medicine showed that 84% of trial participants regained the ability to read letters, numbers, and words after receiving the Prima device.

The microchip measures two millimetres by two millimetres and is implanted beneath the center of the retina. Patients wear augmented reality glasses containing a camera that projects images onto the chip. The device converts light into electrical pulses transmitted to the brain.

Frank Holz, the study’s lead author and chair of ophthalmology at the University Hospital of Bonn, called the implant “a paradigm shift in treating late-stage age-related macular degeneration.” Mahi Muqit, a consultant at Moorfields Eye Hospital in London, said the trial enabled “meaningful central vision restoration, which has never been done before.” The procedure takes less than two hours and requires intensive rehabilitation. Science Corporation, which manufactures the device, has applied for clinical authorization in the United States and Europe.

[$] Explicit lazy imports for Python

Importing modules in Python is ubiquitous; most Python programs start
with at least a few import statements. But the performance impact
of those imports can be large—and may be entirely wasted effort if the
symbols imported end up being unused. There are multiple ways to lazily
import modules, including one in the standard library, but none of them are
part of the Python language itself. That
may soon change, if the recently proposed
PEP 810 (“Explicit lazy
imports”) is approved.

Meta Glasses Drive More Than A Third Of EssilorLuxottica’s Growth

Smart glasses accounted for more than a third of EssilorLuxottica’s growth in Q3 2025.

The French-Italian giant EssilorLuxottica is the largest eyewear company in the world by far. It owns iconic brands like Ray-Ban, Oakley, Oliver Peoples, and Persol, and has exclusive licenses with major fashion companies like Prada, Armani, Burberry, and Chanel. It also owns Sunglass Hut, and has more than 18,000 retail stores in total worldwide.

Meta has so far partnered with EssilorLuxottica for six smart glasses products:

Last year Meta and EssilorLuxottica signed an agreement extending their partnership “into the next decade” to develop “multi-generational smart eyewear products”, And earlier this year, Meta invested €3 billion in EssilorLuxottica, taking a 3% stake.

In its Q3 call with investors, EssilorLuxottica said its overall revenue grew 11.7%, of which “in excess of 4 percentage points” was from its Wearables division, which currently handles the Meta smart glasses partnership and Nuance Audio.

Back in February, its Q4 2024 earnings call, EssilorLuxottica said that the Ray-Ban Meta glasses had sold 2 million units, and in its Q2 2025 call in July that sales had more than tripled since last year, performing “exceptionally well”.

During the February call, the company also announced that its annual production capacity for smart glasses would be increased to 10 million by the end of 2026.

When asked about this on the new call, CFO Stefano Grassi said that because of the “further acceleration” of the smart glasses business since then, the production schedule has now been brought forward, with the company expecting to hit the 10 million annual rate earlier than the end of next year.

Grassi also confirmed that EssilorLuxottica’s smart glasses business is profitable, “in absolute terms”, and that around 20% of buyers opt for official prescription lenses.

The Meta-EssilorLuxottica alliance is by far leading the smart glasses market. But it will face serious competition in coming years.

At I/O back in May, Google announced that it’s working with Warby Parker and Gentle Monster, two of EssilorLuxottica’s rising competitors, to develop Gemini smart glasses. It also plans to work with Kering Eyewear in the future. In June, South Korean media reported that Google was in the final stages of taking a 4% stake in Gentle Monster.

Apple too reportedly plans to launch similar smart glasses, with Bloomberg’s Mark Gurman and supply chain analyst Ming-Chi Kuo claiming that Apple plans to ship as soon as early 2027.

Peanut Allergies Have Plummeted in Children, Study Shows

Food allergies in children dropped sharply in the years after new guidelines encouraged parents to introduce infants to peanuts, a study has found. The New York Times: For decades, as food allergy rates climbed, experts recommended that parents avoid exposing their infants to common allergens. But a landmark trial in 2015 found that feeding peanuts to babies could cut their chances of developing an allergy by over 80%. [non-paywalled source.] In 2017, the National Institute of Allergy and Infectious Diseases formally recommended the early-introduction approach and issued national guidelines.

The new study, published Monday in the journal Pediatrics, found that food allergy rates in children under 3 fell after those guidelines were put into place — dropping to 0.93% between 2017 and 2020, from 1.46% between 2012 and 2015. That’s a 36% reduction in all food allergies, driven largely by a 43% drop in peanut allergies. The study also found that eggs overtook peanuts as the No. 1 food allergen in young children.

The study did not examine what infants ate, so it does not show that the guidelines caused the decline. Still, the data is promising. While all food allergies can be dangerous, 80% of people never outgrow one.

Microsoft’s Latest Windows Update Has a Bug That Makes It Harder to Fix Issues With Your PC

When your PC is acting up, one diagnostic tool at your disposal is the Windows Recovery Environment (or Windows RE). Windows RE offers a series of functions to help you root out whatever is ailing your machine. Using it, you can choose to reset your computer, run an automated diagnosis and repair tool, adjust settings to see if any are causing the issue, uninstall previous updates that might be tripping up Windows, and restore to a previous back Windows backup, among other potentially helpful options.

It’s a necessary feature of the operating system, meant for times when a simple shut down and restart doesn’t help your PC get back to normal operations. So it’s not ideal when Windows ships with a bug that not only breaks part of the OS, but also breaks the part of the OS designed to help fix your PC.

As spotted by Tom’s Hardware, a bug in Windows 11’s October update, KB5066835, hinders your ability to access Windows RE. The recovery environment can still load if you need it, but you’ll find you won’t be able to select any of the options it offers to try to fix your PC. That’s because this bug breaks USB device functionality specifically in Windows RE. Simply stated, your mouse and keyboard will not work in Windows RE, preventing any navigation within the recovery environment.

This is obviously bad news for anyone who wants to use Windows RE to fix a problem with their PC—including, ironically, this Windows RE-specific bug. But you might think that so long as your particular issue with Windows isn’t prohibiting you from actually using your computer, you could live without Windows RE for the time being. As Tom’s Hardware points out, however, it’s not so simple: When your PC has trouble starting up, it will automatically boot into the recovery environment. That’s normally a good thing, since you’ll have the tools to help diagnose and solve the issue. However, when Windows takes you to a screen where you can’t use your mouse and keyboard, or interact with any elements whatsoever, you’re kind of stuck.

The good news is Microsoft is aware of the issue. The company has called out the bug as a known issue in Windows 11, version 25H2, and says it is working on releasing a fix “in the coming days.”

Windows is experiencing other issues, too

Windows is going through it this month. This same October update also broke localhost functionality, which impacted any apps that connect to services running locally on your PC. (Luckily, Microsoft did issue a fix for that bug.) Then, last week, the company also officially ended support for Windows 10, and though it still offers Extended Security Updates for any user that wants to enroll their PC in the program, it puts the security of roughly half a billion PC users into question.

This Windows RE bug is just one more critical issue PC users have to deal with. Hopefully, Microsoft’s next Windows 11 build introduces only fixes, and no additional bugs.

What is Experience AI?

Experience AI is a free educational programme that helps teachers and students learn about artificial intelligence (AI). It was developed by the Raspberry Pi Foundation in partnership with Google DeepMind and includes lessons, classroom resources, and hands-on activities to help students develop a foundational understanding of AI technologies, their social and ethical implications, and the role that AI can play in their lives.

It is based on original research into AI literacy and highlights real-world applications of AI technologies, including through videos featuring research scientists that help to bring the lessons to life for students.

Since we launched the first Experience AI resources in April 2023, they have been used to teach over 2 million students, and that number is growing fast. 

This reach is possible thanks to a global network of Experience AI education partners who work with us to localise and translate the resources and deliver large-scale teacher training in their regions. 

UNESCO recognition

Experience AI was one of four laureates of the prestigious global Prize selected by the Director-General of UNESCO, based on recommendations from an independent, international jury. The jury commended the programme for its strong ethical foundation and wide international reach. 

This year, marking its 20th anniversary, the Prize focused on the theme ‘Preparing learners and teachers for the ethical and responsible use of artificial intelligence’.

The Prize was awarded at a ceremony at the University of Bahrain attended by the Director-General of UNESCO, Ministers of Education of the Gulf Cooperation Council, and members of the Raspberry Pi Foundation and Google DeepMind teams.

I want to say a heartfelt congratulations and thank you to everyone who has worked on Experience AI so far. It has been a fantastic, collaborative effort from colleagues across the Foundation, Google DeepMind, and all of our partner organisations. 

I also want to pay tribute to all of the teachers — all over the world — who have engaged so enthusiastically with Experience AI, for helping us develop the materials, including testing them in your classrooms and providing such thoughtful feedback, and for everything you do, every day, to inspire your students. This recognition is for all of your hard work, diligence, and care. Congratulations and thank you.

Experience AI is provided at no cost to schools, teachers, or students thanks to generous funding from Google.org. We are also very grateful to Broadcom Foundation, which has provided additional funding to support the programme. 

What next for Experience AI? 

We are exceptionally proud to have received this recognition for Experience AI, but we aren’t complacent. Equipping all young people, and their teachers, with a foundational understanding of AI technologies is one of the most urgent challenges facing all education systems.

We have made a great start, and we know there is much more to be done. That’s why we have lots of important updates and developments coming soon, including: 

  • Updating and improving the current lessons: We are finalising an update to the resources to respond to feedback from teachers and students, including significant improvements to make them more accessible. These will be published early in 2026. 
  • Expanding the range of lessons: Alongside the updates to the existing resources, we are developing new lessons. This will include lessons designed for both younger and older learners, as well as integrated lessons that enable teachers to bring AI concepts and skills into subjects such as science, language, and the arts. 
  • Updated and improved professional development: We are also updating and improving the training that we offer to teachers, including both online courses and webinars, and in-person training delivered through the global network of education partners. 
  • AI chatbot for educators: We recently integrated a chatbot into the Experience AI website. Powered by Gemini 2.5, this is intended as a tool to help teachers navigate and understand the concepts and lessons. This is an early experiment and we’d love to get your feedback, so please give it a try and let us know what you think. 
  • Expanding the global network of partners: We currently have partners supporting teacher professional development in 25 countries, from Malaysia to Mexico. Over the coming year we will be launching partnerships in at least 15 more countries. If your organisation is interested in becoming a partner, you can let us know by filling in this form.

Spotify now lets people follow venues to find out about concerts

Spotify just introduced a feature that lets users follow their favorite concert venues. This will provide people with updates and details about upcoming concerts.

Once a venue is selected as a favorite, it gets saved in a user’s library. Browsing each venue provides information on scheduled concerts, general announcements and other stuff. Folks can even filter upcoming shows by genre. Clicking on a specific spot will also pull up “tailored suggestions for other venues” in the vicinity.

Spotify’s new venue-tracking platform will offer links to each location’s “official ticketing partner” to make it easier to scoop up some tickets. The company says it currently tracks over 20,000 venues throughout the globe, from “iconic arenas to beloved independent clubs.”

Spotify also announced a change to its live event feed. This will now update daily instead of weekly. For the uninitiated, this tool tracks when artists are touring and lists nearby live events.

The platform recently added yet another tool for concert discovery in the form of custom playlists that highlight artists with upcoming shows in the area. These playlists update every week and include 30 songs.

These are welcome tools, as artists don’t get paid a whole lot from streaming platforms, instead relying on live ticket sales. The features could also help stem some of the bad press that’s been coming Spotify’s way lately, thanks to CEO Daniel Ek’s involvement with a weapons manufacturing company and the platform going running recruitment ads for controversial government entities like ICE.

India Draft Plan Reveals $21 Trillion Net-Zero Investment Need

India will need as much as $21 trillion to achieve its climate goals and lift its population out of poverty, according to a draft government plan seen by Bloomberg. From the report: The estimate offers a first glimpse of how the country intends to live up to its target of net zero emissions by 2070. The updated scenario implies hitting peak emissions in 2045, which is a decade earlier than the current trajectory.

India is already being severely battered by the fallout of climate change, as deadly floods and heat waves become more destructive each year. But the need to mitigate the emissions that feed climate change has historically been at odds with India’s priorities of economic growth and energy security, with the latter still mostly provided through coal. The new plan shows India will seek to achieve climate and economic development goals simultaneously, with low-carbon options envisaged for much of its yet-to-be-built residential and industrial infrastructure.
