An anonymous reader shares a report: Before the potential of the internet was appreciated around the world, nations that understood its importance managed to scoop outsized allocations of IPv4 addresses, actions that today mean many users in the rest of the world are more likely to find their connections throttled or blocked.
So says Cloudflare, which last week published research that recalls how once the world started to run out of IPv4 addresses, engineers devised network address translation (NAT) so that multiple devices can share a single IPv4 address. NAT can handle tens of thousands of devices, but carriers typically operate many more. Internetworking wonks therefore developed Carrier-Grade NAT (CGNAT), which can handle over 100 devices per IPv4 address and scale to serve millions of users.
That’s useful for carriers everywhere, but especially valuable for carriers in those countries that missed out on big allocations of IPv4 because their small pool of available number resources means they must employ CGNAT to handle more users and devices. Cloudflare’s research suggests carriers in Africa and Asia use CGNAT more than those on other continents.
Cloudflare worried that could be bad for individual netizens. “CGNATs also create significant operational fallout stemming from the fact that hundreds or even thousands of clients can appear to originate from a single IP address,” wrote Cloudflare researchers Vasilis Giotsas and Marwan Fayed. “This means an IP-based security system may inadvertently block or throttle large groups of users as a result of a single user behind the CGNAT engaging in malicious activity. Blocking the shared IP therefore penalizes many innocent users along with the abuser.”
If you’ve joined a private Facebook group—counting on your membership and posts to be visible only to those approved to join—and receive a notification that said group is about to go public, you don’t need to panic. While Meta is now allowing admins of previously private Facebook groups to change the status to public, it is also assuring users that past activity will remain private.
Private Facebook groups can be made public
According to Meta’s post announcing the update, the option to transition from private to public allows small groups to grow into larger communities that are more easily found, with content visible to anyone (even people who aren’t on Facebook). Any admin can set their group privacy settings to public, which will trigger a three-day review period in which all admins have the opportunity to decline the conversion. If no one cancels the request, the group will go public.
Groups can revert back to private at any time, at which point new members will again require admin approval. (These members will be able to see all content from before the conversion.)
Your private posts are still protected
When a private group goes public, all existing posts, comments, and reactions will remain visible only to members, admins, and moderators who were already in the group but be hidden to new members and the general public. Member lists will also be hidden to everyone except admins and moderators. Any content added after the conversion will be visible to anyone.
If a group you’re in is converted from private to public, you’ll get a notification about the change. You’ll also see a notification the first time you post or comment in the newly public group reminding you that your activity is now visible. When you go to post, look for the globe icon, which indicates that your content is public.
Going all the way back to early 2024, Intel Linux engineers have been working on supporting an Adaptive Sharpening Filter new to Lunar Lake. While Lunar Lake later launched in September 2024, the Linux patches for this feature remained under review and discussion. Besides the Intel driver implementation itself for Lunar Lake and newer, it also ushers in a new DRM sharpness property to help standardize such functionality for user-space that could be used by other kernel graphics drivers. Finally with the upcoming Linux 6.19 kernel, this Intel Content Adaptive Sharpness Filter “CASF” feature is being introduced to the mainline kernel…

We’re only a few days into November but it’s not too early to jam out to big savings on Black Friday tier discounts. Quite literally – the annual sales frenzy has already begun at Best Buy with deals on a wide assortment items, including a monster discount on a high-end wireless soundbar system with a subwoofer and Dolby Atmos support.

When you think of network tunneling, “lightweight” and “enterprise-grade” rarely appear in the same sentence. NodePass, an open-source project, wants to change that. It’s a compact but powerful TCP/UDP tunneling solution built for DevOps teams and system administrators who need to manage complex network environments without wading through configuration files or rigid infrastructure setups.
AWS today announced Fastnet, a subsea fiber-optic cable that will link Maryland’s Eastern Shore to County Cork, Ireland. The project marks Amazon’s first wholly-owned subsea cable system after previously participating in similar ventures through consortiums.
The cable will carry data at speeds exceeding 320 terabits per second. Amazon did not disclose construction costs but expects the system to begin operations in 2028. The company is burying the cable roughly one and a half meters deep across the ocean floor. Installers will bore a horizontal tunnel from shore to shore. Amazon has added protective steel wiring to guard against ship anchors and deliberate sabotage.
While there are lots of great Black Friday sales on cheaper devices, it’s the big ticket items that really make a world of difference. Take Apple’s 2024 Mac mini M4, which has dropped to $499 from $599 as part of early Black Friday deals. The 17 percent discount brings Apple’s mini desktop computer with 16GB of RAM and 256GB of SSD to only $30 more than its all-time low.
We gave the Mac mini M4 a 90 in our review, in part, because it packs an incredible amount of power into such a small design. It also has front facing USB-C and headphone ports, a first for the Mac mini lineup. Plus, it starts with 16GB of RAM, an upgrade from its predecessors.
However, if you want more memory or storage, the other Mac Mini M4 models are also on sale. You can get 16GB of RAM and 512GB of SSD for $690, down from $799. Then there’s the option for 24GB of RAM and 512GB of SSD at $890, down from $999. Plus, if you want to bundle in three years of AppleCare+, each model ends up being about $100 cheaper than normal.

Dangerholm’s latest project is these prototype aero rims with ludicrous proportions that may shape the future of gravel wheel design.
The new gravel wheels feature a massive 52mm width and 70mm depth, and are said to be optimised around 2.1 to 2.25in mountain bike tyres.
Dangerholm, whose real name is Gustav Gullholm, says the project is purely experimental, blending aerodynamics and new ride characteristics, with zero production plans.
The prototype was done in collaboration with the Canadian design and engineering firms Faction Bike Studio and Lx Lab.
While the wheels aren’t for sale, they may break the ice for more radical designs down the line.
Dangerholm says the best width combination in testing was 2.25in, with only a small trade-off to 2.1in in width, but more air volume to play with. Dangerholm
We have seen gravel tyres becoming wider and wider over the past couple of years, with brands and racers seeing the benefits of increased grip and a more cushioned ride feel.
The theory came from road tyres, where the traditional thought of thinner tyres being faster due to less drag was put to bed.
Dangerholm says tyre size has been something that’s left him scratching his head when it comes to regular gravel bikes.
“Sure, I get that a 40-45mm tyre can be really fast on fine hardpack, but otherwise I didn’t really see the appeal of trading away the wide yet relatively lightweight MTB tyres,” he says.
Mountain bike tyres tend to offer more grip than gravel tyres. Dangerholm
This new prototype has been designed around 2.1 to 2.25in mountain bike tyres, with Dangerholm saying: “I have nothing but positive things to say. So much so that I don’t want to move back to 30mm rims no matter the weight savings.”
“Going with a 45mm internal width is pushing it to the extreme end of the spectrum, but I’d rather test the max size option right away and learn from it.
“Oftentimes, when experimenting, you want to find the limit by pushing a tiny bit too far, then step back a little. My guess is that a 40-42mm internal width rim with thick sidewalls to maintain a 50-52mm external width would be the optimal numbers.”
A drop-bar Scott Spark was used to display the wheels. Dangerholm
This puncture resistance enables riders to run lower tyre pressures, meaning they can achieve a more cushioned feel on rough gravel surfaces.
Dangerholm says he has to give credit to Zipp’s XPLR wheels, which opened his eyes to using wider tyres.
“The aero aspect was a big deal, but I’m one of those riders who really dislikes a squirmy feel from my tires which has had me riding some pretty high tyre pressures,” he says.
“But now, with 32mm inner width rims paired to 40-45mm tyres, I could suddenly drop the pressure while having improved stability, along with better comfort, grip and rolling speed on the rough stuff.”
The staggered rim profile is designed to offer better aerodynamics. Dangerholm
In this project, Dangerholm has also focused on aerodynamics, saying: “The aerodynamics is quite self-explanatory, with the 52mm-wide and 70mm-deep rim profile hopefully improving the aerodynamics enough to provide some gains.
“Sure, you’re fighting an uphill battle from the start with a knobby wide MTB tyre, but that also means that you have a big reason to improve it.”
Explaining how Faction shaped the industrial design and overall look of the wheels, Dangerholm says: “I was expecting maybe 2-3 options, but early on I was presented with a whole bunch of different rim shapes to consider. And not only that, but various graphics too, which were surprisingly helpful as it accentuated the designs even further, making them easier to compare.”
Only four rims are being made and there are no plans to go into production.

Meta has unveiled an overhaul for the WhatsApp experience on Apple Watch. The first official such app for the wearable is rolling out today and it includes support for what the company calls “many requested features.” You’ll now be able to see everything your friends are saying via your Apple Watch as longer WhatsApp messages won’t be truncated. You’ll have the option to respond to messages with quick emoji reactions.
The Apple Watch app will enable you to record and send voice messages from your wrist. In addition, you’ll be able to see call notifications with details on who’s trying to get in touch with you without having to look at your iPhone. Other features include the ability to see “clear images and stickers” on the Apple Watch app, as well as more of your chat history. Of course, there’s still end-to-end encryption for your messages and calls.
The new app is a major upgrade over only being able to reply to WhatsApp messages via mirrored iPhone notifications on Apple Watch. To use it, you’ll need an Apple Watch Series 4 or newer that’s running at least watchOS 10.
It’s a little wild that it has taken Meta so long to create a proper Apple Watch app. Even BlackBerry made a BBM app for the wearable, and that was a decade ago. But perhaps it shouldn’t be too surprising given how long we had to wait for an Instagram iPad app.

Julia is a modern programming
language that is of particular interest to scientists due to its high
performance combined with language features such as Lisp-style macros, an
advanced type system, and multiple dispatch. We last looked at Julia in January on the occasion of
its 1.11 release. Early in October Julia 1.12
appeared, bringing a handful of quality-of-life improvements for Julia
programmers, most notably support, though still experimental and limited,
for the creation of binaries.
Dick Cheney, who served four Republican presidents and became one of the most powerful and controversial vice presidents in American history as an architect of the post-9/11 war on terror, died at 84. His family said he died from complications of pneumonia and cardiac and vascular disease.
Cheney served as vice president under George W. Bush for two terms beginning in 2001 and relentlessly advocated for the 2003 invasion of Iraq. Many Americans came to view the war as a strategic and humanitarian disaster. The conflict had far-reaching policy and political consequences that helped turn the public against intervention and upheaved Republican politics. Cheney continued to defend the invasion long after leaving office in 2009.
He had heart disease for most of his life and underwent a transplant in 2012. That allowed him to live to see his daughter Liz Cheney follow in his political footsteps to become a House GOP leader. Before serving as vice president, Cheney was defense secretary under George H.W. Bush and chief of staff to Gerald Ford at age 34.
The AI arms race is afoot and in a bid to stay in front of the 8-ball, OpenAI is forming a multi-year partnership with Amazon Web Services (AWS) to rapidly scale agentic workloads.

Amazon has launched its new and improved AI assistant in the Amazon Music app. From today, anyone signed up to Alexa+ Early Access with the latest version of the app downloaded to their iOS or Android device can start using Amazon’s reimagined virtual assistant for music discovery and organizing their libraries.
To access the chatbot, you tap the “A” button in the lower right corner of the screen when Amazon Music is open. You can then test its knowledge by asking it a range of questions, from something as basic as finding a recently released song by a particular artist, to more complex searches based on a single lyric or the name of the TV show the song you’re trying to find is featured in.
Alexa+ is designed for more conversational interactions, so you can use natural language prompts and then ask follow-up questions as you would if you were talking to a friend, to narrow down its search results. Amazon says you can search for specific eras, moods and instruments, as well as telling Alexa what you don’t want it to serve up.
Alexa+ can also be used for playlist creation, allowing you to request something as specific as a high-energy running playlist with songs from a particular decade that starts with a song from a certain artist. You can also be more vague, asking for something that fits your current mood or the time of day.
Alexa+ in Amazon Music is being marketed not only as an AI tastemaker and personal DJ, but also a music expert, so you can ask it things like the inspiration for a song’s lyrics, where an album charted and questions about upcoming live performances.
Alexa+ has been gradually rolling out in Amazon’s various smart devices since the beginning of the year, with mixed results. You’ll be using it in everything from new Ring devices, to the latest Kindles and Vega, Amazon’s new smart TV operating system. It’s also built into the new Echo Studio speaker, and Engadget’s Billy Steele was impressed by the AI assistant’s more human-like conversation skills, even if it’s still prone to basic errors right now, such as getting the day of the week wrong in a response.
Alexa+ is currently available in Early Access for all tiers of Amazon Music. Eventually it’ll be free to all Prime members, and available to non-Prime members for $20 per month (more than an Amazon Prime subscription on its own).

Whether you’re hosting a party or just cleaning the house, sometimes it’s nice to have audio in multiple rooms. You could do that by running wires through your house, or by purchasing a multi-room audio system, but if you have a Mac you don’t have to do any of that.
There’s a feature that makes it possible to send your Mac’s audio to multiple speakers, including Bluetooth ones. The feature is a little obscure, though—you won’t find it in System Settings, or anywhere obvious.
No, to send audio to multiple devices on your Mac you need to open an application called Audio MIDI Setup, which you can find using Spotlight or by browsing to Applications > Utilities in Finder.
Credit: Justin Pot
Open the application and click the + button in the bottom-left corner, then click Create Multi-Output Device. You will see a list of all audio devices, including the built-in speakers, any wired audio outputs that are connected, any Airplay-compatible devices on your network, and any Bluetooth devices that support audio.
Credit: Justin Pot
Check as many of these as you like. You can give a name to your combined audio device, if you like, by clicking and holding the current name in the left-hand sidebar. Then you can switch to your new combined audio device by clicking the audio icon in your menu bar and selecting it.
I recommend putting on some music and testing things out, adding or removing devices. I had the best results by checking one device connected to my Mac using a wired and another that is connected by Bluetooth. Multiple Bluetooth devices tended to get out of sync quickly, though you can alleviate the syncing issues by checking the Drift Correction box for your wireless devices.
This isn’t a perfect replacement for a proper multi-room audio system, but it works surprisingly well without the need to buy anything, run wires in your walls, or even purchase any software. Try it out the next time you feel like walking around your house listening to music.
EF Pro Cycling is currently selling its old team bikes – and with big discounts.
The team has two models of Cannondale SuperSix Evo 4 Hi-Mod for sale on its website, from the 2024 and 2025 seasons.
Available in sizes from 44cm to 58cm, the 2024 model has the biggest reduction. The bike comes with a Shimano Dura-Ace groupset, with an FSA Gossamer Pro crankset (and either a Dura-Ace or Ultegra cassette and chain), plus FSA wheels, a Prologo saddle and Vittoria tyres.
The bike is on sale for £3,848, which is over £8,000 less than the consumer replica version, which Ash Quinlan described as “one of the few all-round race bikes to feel truly at home wherever you ride it”.
The 2025 EF Pro Cycling Cannondale SuperSix is on sale for £4,509. This bike also has a Shimano Dura-Ace groupset, but with an FSA K-Force team-edition crankset and the option to upgrade the wheelset.

EF Pro Cycling says its pros raced and trained on these bikes, and they’ll only be on sale for a limited time.
Although the graphics on both bikes include Cannondale’s top-spec Lab71 branding, EF Pro Cycling says the bikes are Hi-Mod specification. This means they will have a very slight weight penalty over the Lab71 bikes.
Amazon’s data-center expansion turned Umatilla, Oregon into an unlikely nerve center for American infrastructure investment. The community of roughly 8,000 residents has seen home prices double and local government budgets surge from $7 million in 2011 to a hundred and $44 million in the past fiscal year. Yesenia Leon-Tejeda, a Realtor and daughter of Mexican-born farmhands who once worked 12-hour shifts at a distribution center, is now on pace to close 35 deals this year.
Federal data shows investment in software and information-processing equipment drove most of America’s GDP growth in the first half of 2025. Goldman Sachs estimated that roughly 72% of all server-farm capacity sat in just 1% of counties as of July. The region’s hydroelectric dams and cheap power attracted Amazon Web Services more than a decade ago. Growth has brought rising costs for housing and child care. Political tensions over spending erupted this year when Mayor Caden Sipe sued the city manager and council members.
