F1’s new engines are causing consternation over compression ratios

There’s still another couple of months before the 2026 crop of F1 cars takes to the track for the first preseason test. It’s a year of big change for the sport, which is adopting new power unit rules that place much more emphasis on the electric motor’s contribution. The switch to the new power units was meant to attract new manufacturers to the sport, and in that regard, it has succeeded. But controversy has erupted already as loopholes appear and teams exploit them.

Since 2014, F1 cars have used 1,000 hp (745 kW) power units that combine a turbocharged 1.6 L V6 gasoline engine with a pair of hybrid systems. One is the MGU-H, which recovers energy from (or deploys it to) the turbocharger’s turbine; the other is a 160 hp (120 kW) MGU-K that harvests and deploys energy at the rear wheels. Starting next year, the MGU-H is gone, and the less-powerful 1.6 L V6 should generate about 536 hp (400 kW). That will be complemented by a 483 hp (350 kW) MGU-K, plus a much larger battery to supply it.

And the new rules have already attracted new OEMs to the sport. After announcing its departure at the end of 2021—sort of— Honda changed its mind and signed on to the 2026 regs, supplying Aston Martin. Audi signed up and bought the Sauber team. Red Bull decided to build its own internal combustion engines, hiring heavily from the Mercedes program, but Ford is providing Red Bull with the MGU-K and the rest of the hybrid system. And Cadillac has started an engine program, albeit one that won’t take the grid until 2029.

Apple Fined $116 Million Over App Privacy Prompts

Apple has been fined $116 million by Italy’s antitrust regulator over the “excessively burdensome” privacy rules it imposes on third-party apps. From a report: The Italian Competition Authority (AGCM) says that Apple abused its dominant app store market position by burdening developers with “disproportionate” terms around data collection that exceed privacy law requirements, compared to rules for native iOS apps.

The fine specifically targets the App Tracking Transparency (ATT) policy Apple launched in 2021, which requires third-party developers to ask users for consent twice to track their data across other apps and websites. Apple’s own apps can obtain this permission in a single tap. AGCM says that the burden of consenting twice led to a reduction in user consent rates for advertising profiling, thus harming developers whose business models depend upon revenue generated by personalized ads.

Astronomers Stunned To Witness Black Hole Twisting Fabric Of Spacetime

Astronomers Stunned To Witness Black Hole Twisting Fabric Of Spacetime
Astronomers have finally captured a black hole twisting the very fabric of spacetime. This phenomenon, known as frame-dragging or Lense-Thirring precession, confirms a cornerstone of Einstein’s general theory of relativity by showing that massive, rotating objects don’t just spin in situ—they drag it along with them like a spoon stirring honey

The Out-Touch-Adults Guide to Kid Culture: The Top 10 Slang Terms of 2025

2025 is limping to a merciful end, so I’m taking a look back at the year in slang. Below are ten examples of youth patois, chosen for both their popularity and for what they reveal about generations A and Z. Like most slang, these words and phrases evolved over time, so while many didn’t first appear in 2025, but this is the year they gained popularity. (If you want a more complete list of youth slang, check out my guide to Gen Z and Alpha slang.)

6-7

By far the most popular slang word of 2025 was “6-7.” These two previously unremarkable numerals rose to unprecedented popularity with young people this year, to the consternation of legions of educators and parents. It’s perfect Gen A slang because it doesn’t have a literal meaning, like a lot of younger people culture, but it’s a sort of self-contained joke. Often, the idea is to use the phrase in conversation: if someone asks how tall you are, what you scored on a test, or what time it is, you might respond “six-seeeeeven.” Hilarious.

6-7 took off when Philadelphia artist Skrilla released “Doot Doot (6 7)” in February.

From there, it was repeated in schoolyards and TikTok posts for no reason except maybe that it’s fun to say. In a month or two, 6-7 reached full slang saturation, and everyone learned what it means (or doesn’t mean). Dictionary.com named 6-7 its word of the year. It spawned spin-off numbers like 41 and 93. Older people waited for it to end, but 6-7 didn’t end. We’re almost a year in, and kids are still saying it constantly. So it means something to them. But what? 6-7’s lack of literal meaning highlights the difficulty of defining a generation that seems uninterested in (or unable to) define itself.

Brainrot

Brainrot describes online content, usually videos and meme images, that are stupid and meaninglessness. They’re generally loud and assaultive, too: Brainrot is not subtle. It also described the supposed effect that consuming this kind of material has on kids. One of the earliest and most well known pieces of brainrot is “Skibiddi Toilet,” a series of YouTube videos that has billions of views. The genre has evolved from there, and now often consists of reframing and remixing obscure memes to create content that is almost entirely absent of meaning, like this Italian brainrot. Younger kids particularly spend a ton of time watching brainrot content, so it is likely shaping the collective worldview of Generation Alpha, but it’s hard to say what the result will be.

Slop

“Slop” describes the hundreds of millions of cheesy-looking, unsettling, AI-generated images, videos, and songs that have hit the internet since artificial intelligence gained popularity over the last couple years. Ease of production means that slop is rapidly taking over human-produced content, and younger people will live in a slop-dominated future. As a generation, they may have more intellectual and artistic connection to machines than they will with other humans.

Mason

A Mason (or Mason 67 Kid) is a white, suburban Gen Alpha boy who plays baseball, rocks a fluffy “ice cream” haircut, and says “6-7” a lot. His sunglasses are Pit Vipers. He wears Yeezy slides. His polyester-as-hell ice cream shorts can be purchased at Dick’s Sporting Goods. There’s no way to know whether the word “Mason” will resonate enough to be remembered later, but it is, as far as I know, the first popular slang term to describe a dominant subculture in Generation Alpha. If it sticks around, it could be the equivalent of describing Boomers as “hippies” or Gen X as “slackers.”

“Reheating your own nachos”

This slang phrase describes artists whose new works are seen as trying to recapture what was good about their previous artistic output. It’s not a widely used phrase outside of online fandom communities, but I’m including it to represent the kind of hyper-specific slang that comes from the relative rarity of shared cultural experiences among young people. They’re balkanized, and every fandom, hobby, and interest group has its own language that is often not understood outside of the specific group.

Sendy

An adjective that describes a person who does bold and/or exciting things, “sendy” is often used in the phrase “let’s get sendy,” which means something like “let’s do something big/crazy.” It also often means “Iet’s get drunk.” It’s an example of a slang word coming from a niche community and spreading into the larger culture.

It started in rock-climbing communities in the ’80s or ’90s, where “ascend it” was shortened to “send it” and used to encourage people to “go for it. “Send it” was then adopted by skaters, snowboarders, and other action-sports fans, and eventually slid into the mainstream culture when it was used in this video from influencers The Nelk Boys. Being able to so often pinpoint the exact source of a slang word is another unique feature of Gens Z and A.

80/20 rule

80/20 can refer to various scientific and organization principles, but that’s not how kids usually use it. An axiom popular in online incel spaces, the 80/20 rule is the idea that 80% of women only date the “top” 20% of men. The “male loneliness epidemic” and increased social isolation resulted in many younger men accepting controversial, unproven ideas like this as empirical truth, and they have spread from online communities of misfits to the general population of Generations A and Z.

Performative male

This insult is aimed at young men whose tastes, hobbies, and lifestyle are seen as a performance aimed at obtaining societal approval, especially the approval of young women. Like the 80/20 rule, “performative male” came from online spaces dominated by incels, and has since spread to the larger culture and expanded in meaning to the point that even reading in public is seen as performative. The problem with “performative male” is that it only refers to one kind of performance. The opposite performance of masculinity—the “Alpha male” envisioned by Andrew Tate and various lesser Tate-lets—is thus seen as genuine. It’s an illustration of younger people’s growing toxic masculinity as well as the strict policing of self-expression that comes from every public moment ending in potentially viral online ridicule.

Aura farming

The flip side of the “performative male,” aura farming is intentionally cultivating and projecting a cool, charismatic, or impressive image and getting away with it. It’s generally seen as a good thing: Someone who is succeeding at their public “performance” of the self and actually coming across as cool to others is aura farming. Although one of pitfalls of aura farming is trying too hard, an experience that isn’t native to younger generations—in the past, you might have called it “being a poser.”

“Beez in the trap”

“Beez” means something like “I am always” and “trap” comes from “trap house,” but has a more broader meaning like “place of business.” So “beez in the trap” means something like “I am at the place of business, hustling,” but I’m not including it here for the words, but for how they took off online in 2025 and what it says about young people.

The rest of the slang in this column paints a fairly bleak picture of youth, but we shouldn’t forget the creativity, passion, and heart that also defines Generations Z and A. “Beez in the trap” is an example of how younger people are re-mixing and re-shaping the culture we’ve left them into something of their own that is often amazing.

The meme works like this: Two people stand back to back. Person one passionately lip-syncs the chorus of 4 Non Blonde’s song, “What’s Going On.” The camera rotates to person two, who chimes in with Nicki Minaj’s less existentially angsty track. It’s one of those things that just sparks joy in a way that defies explanation and is quintessentially “young person in 2025.” Enjoy:

US To Impose Tariffs on Chips From China

An anonymous reader shares a report: The United States will take action against China’s semiconductor industry, setting new tariffs on chips from China from June 23, 2027, that have 0% duties currently, the US Trade Representative said.

The announcement comes following a year-long investigation into China’s chip imports into the United States, launched by the Biden administration and led by the U.S. Trade Representative. “China’s targeting of the semiconductor industry for dominance is unreasonable and burdens or restricts U.S. commerce and thus is actionable,” the agency said in its release.

Will Your Smart Vacuum Still Work After It Stops Being Supported?

My Neato D5 Connected was once a willing workhorse, but, today, things aren’t looking so good. I recently caught an email from the company alerting me that it shut down my vacuum’s cloud servers. Now, my once capable Neato is just a LiDAR-equipped vacuum with a soul that’s been deprecated. Without cloud servers, the “smart” is gone.

This could be the lobotomized future awaiting Roomba users. Earlier this month, the company behind the pioneering smart vacuum, iRobot, filed for bankruptcy. The remainder of the business will go to its primary manufacturing partner—the one it owes all that money to—Shenzhen Picea Robotics. It’s a stark reminder that the longevity of a connected smart device depends entirely on the financial health of the company that made it.

I’m not giving up, however. I’m now attempting to get the Neato D5 back into business. Whether you have a Neato, a Roomba, or another robot vacuum approaching the end of its connected, you can mirror my steps to keep your device cleaning.

Switch your robot vacuum to manual

Following the above email, I tried earnestly to get the Neato back online and back into a routine. I ended up reviving my original account by some miracle, though I have absolutely no access to the vacuum via the app as it currently is.

Luckily, there is already a community of folks working to restore the cloud service that once enabled Neato’s robot vacuums to schedule themselves. Neato-connected lets you use Home Assistant to manage the brand’s devices without the cloud. This is the best choice for experts if the goal is to revive the robot vacuum to its full capacities.

Neato has already said that the robots will continue to work manually. The D5 has LiDAR, so it can still physically “see” its way around a floor plan. And although you can’t schedule the device or remotely control it, you can still get up and push a button to start a cleaning session. If you want to be super extra, Switchbot makes an affordable button-pushing gadget you can install near the vacuum dock to trigger it from your phone, essentially “hacking” a remote start.

The other headache of trying to keep old hardware from going extinct is figuring out if its parts and mechanics still work. My Neato D5, for example, still hasn’t successfully managed a manual cleaning session. After some troubleshooting, which involved several factory resets, disconnecting and reconnecting the battery, and cleaning debris from all the sensors, it turns out that one of the LiDAR turrets—the hat on top—needs a fix. The vacuum won’t start until that’s addressed, since it literally can’t navigate without that system spinning at a precise speed.

The Neato D5 is going to require some surgery. I am either going to fix it by stabilizing a band, or buy a replacement part from eBay and have someone more tech-savvy help with the install. There’s always the option to donate it to a better cause, too. Rather than hold on to an eight pound paperweight rotting away in the utility closet, it can get a second life with a local robotics group, since Neato vacuums have a reputation for being highly scrappable due to their laser sensors.

Even cheaper robot vacuums, like an Ecovacs, can find a second life this way. While they aren’t as easily “hackable” as Neato (or a Roomba), there are plenty of high school robotics teams that can disassemble the devices to retrieve motors and wheels.

Never throw a robot vacuum into the trash. If the device is truly dead and unusable for parts, look into responsibly recycling the Lithium-ion battery as well as the plastic and metal shell with an e-waste recycler.  

Preparing for the end of Roomba

If you own a Roomba, you aren’t offline yet. iRobot is currently undergoing a restructuring, and the company has stated that app functionality and firmware updates will continue as usual. But inevitable change is coming if Neato’s trajectory is any indication. We don’t know exactly how Roomba’s business will go now that it has changed ownership. Existing Roombas rely on the cloud for much of their flagship functionality, like Smart Maps, which help with specific room targeting. Losing the ability would be a major blow to the hardware’s legacy.

You should prepare for what’s to come, even if it involves a little over-preparing. Stockpile replacement parts now, while they’re still available. Although Roomba’s manufacturer has taken over the business, older models will fall by the wayside as a new generation of robot vacuums is introduced. If you want to get a few more lives out of your Roomba, buy at least a two-year supply of authentic, first-party brushes, rollers, and HEPA filters. Skip the third-party stuff.

You’ll also want to invest in Roomba’s dual-mode virtual wall barriers. Buy them used on eBay. These will come in handy if Roomba’s servers ever go offline, since they act as infrared lighthouses to help direct the Roomba’s path. You’ll be able to use these with Roomba’s “Clean” button, its manual mode that doesn’t require the internet to start. You’ll also want to look into downloading your Smart Maps, in case you can integrate them later.

If that isn’t enough for you, there is a vibrant community of tinkerers who have long been dedicated to liberating Roombas from the clutches of the cloud. Projects like rest980 and dorita980 let tech-savvy users host their own local control servers, though this often involves a third-party device such as a Home Assistant hub.

Ending the e-waste cycle

History tends to repeat itself in the gadget world. You can at least future-proof your buying decision by recognizing that obsolescence is a possibility down the line. This applies to any connected gadget, from big-name brands to small ones.

Matter, the smart home specification that’s been quietly rolling out over the past few years, will be more helpful for aging smart gadgets like this, especially since its latest release. It now enables local smart-home control for robot vacuums, so you don’t need a cloud service to connect. The vacuum talks directly to your phone or smart hub instead. There are also brands like Roborock that advertise that their robot vacuums have local-only modes. You can even install another community-managed project, Valetudo, on those brands and go completely corporate-free.

Or, you could go offline. Most connected home gadgets have variants that use a physical remote control instead. Eufy still makes versions of its robot vacuums without wifi, with no cloud features to worry about going extinct.

I’m waiting before I buy eBay parts for the Neato D5 Connected. I need to see if I can fix what’s broken with some finagling. It’s a bummer I didn’t think of preparing for the end of the device’s life earlier—like when Neato’s parent company announced its eventual shutdown two years ago—to give it a second life and save it from abject hardware failure. If all else fails, I can find it a good home with a robotics team or educational program that can put its parts to good use. I will have considered that a well-lived life for a connected gadget.

[$] Verifier-state pruning in BPF

The BPF verifier works, on a theoretical level, by considering every possible
path that a BPF program could take. As a practical matter, however, it needs to
do that in a reasonable amount of time. At the

2025 Linux Plumbers Conference
, Mahé Tardy and Paul Chaignon
gave a detailed explanation
(slides;
video) of
the main mechanism that it uses to accomplish that: state pruning. They focused
on two optimizations that help reduce the number of paths the verifier needs to
check, and discussed some of the complications the optimizations introduced to the verifier’s
code.

China Bans E-commerce Platforms From Forcing Lowest Prices or Abusing Algorithms

China has unveiled new rules to rein in aggressive pricing tactics by online platforms, prohibiting e-commerce operators from forcing merchants to offer discounts or setting different prices based on user demographics without consent. The 29-article regulation — jointly issued over the weekend by the National Development and Reform Commission, State Administration for Market Regulation (SAMR), and Cyberspace Administration of China — lays out detailed compliance requirements that target several long-standing pain points as competition among internet giants has often eroded the rights of both consumers and merchants.

To restore merchant autonomy on pricing, the rules ban platform operators from leveraging their dominant scale to impose “lowest price” agreements. Platforms are prohibited from using traffic throttling, search ranking demotions, or algorithm penalties to pressure merchants into predatory price-cutting or exclusive pricing arrangements.

This Sony Wireless Portable Speaker Is Nearly 50% Off Right Now

We may earn a commission from links on this page. Deal pricing and availability subject to change after time of publication.

The Sony ULT Field 5 is currently $191.95 on Amazon, down from $349.99, and that price drop is what finally makes this speaker feel properly positioned.

At full price, it was competing with larger, louder options that offered more raw power for the money. With this discount, it makes more sense as a mid-size outdoor speaker that prioritizes bass, durability, and flexibility. PCMag gave it an “excellent” rating, largely because it delivers deeper low-end sound than most speakers in its size class without becoming unwieldy. This is neither a pocket speaker nor a party cannon. It is designed to strike a balance between portability and sound impact, where both are important.

Physically, the Field 5 feels built for abuse. The rectangular body is wrapped in a tough fabric mesh, with passive radiators on each end and subtle LED lighting around them. Those lights can be customized or turned off entirely. The speaker is rated IP67, so dust is a non-issue, and brief drops into water should not cause panic. On top, the controls are simple and tactile, including a large ULT button that changes how the bass behaves. ULT 1 leans into deeper rumble, while ULT 2 pulls things tighter for a more punchy sound. Bass is the clear strength here. It hits harder than you would expect from a speaker this size. The trade-off is in the highs, which can sound a little thin unless you tweak the EQ.

Connectivity is where the Field 5 shows its versatility. Bluetooth 5.3 supports multipoint connections, and Sony’s Party Connect lets you link multiple compatible speakers, though they all need to be from Sony, since this speaker does not support Auracast. There is also a 3.5mm AUX input, which is becoming rare on portable speakers and is useful for wired sources. Codec support includes SBC, AAC, and LDAC, which is a plus for Android users who care about audio quality. Battery life is rated at up to 25 hours, and fast charging delivers about two hours of playback from a 10-minute charge. The USB-C port can also charge your phone in a pinch.

This speaker is still pricey compared to simpler Bluetooth options, and it favors bass over balanced clarity. Still, if you want a rugged speaker with strong low-end and flexible inputs, this deal makes it far easier to justify.


Apple’s iOS 26.3 will introduce proximity pairing to third-party devices in the EU

Apple is making it a little easier to use third-party devices with iPhones in order to comply with Europe’s Digital Market Act (DMA), MacRumors reported. For iOS 26.3, Apple’s devices will support third-party proximity pairing and notifications in Europe only, according to the latest beta notes. That will make it a bit easier to connect devices like Sony headphones or receive notifications from an iPhone on Wear OS smartwatches — provided manufacturers support the new feature. 

“The DMA creates new opportunities for developers to bring to market innovative products and services in Europe,” an EU spokesperson told The Wall Street Journal. “This is another step towards a more inter-connected digital ecosystem to the benefit of all EU citizens.” The EU Commission added that the functionality will be “fully available” in the bloc in 2026.

The new capabilities are as follows:

  • Proximity pairing – Devices like earbuds will be able to pair with an iOS device in an AirPods-like way by bringing the accessory close to an iPhone or iPad to initiate a simple, one-tap pairing process. Pairing third-party devices will no longer require multiple steps.

  • Notifications – Third-party accessories like smart watches will be able to receive notifications from the ‌iPhone‌. Users will be able to view and react to incoming notifications, which is functionality normally limited to the Apple Watch. Notifications can only be forwarded to one connected device at a time, and turning on notifications for a third-party device disables notifications to an Apple Watch.

Proximity pairing is a relatively minor quality-of-life upgrade, allowing you to connect with a tap via NFC rather than diving into the Bluetooth settings. However, there’s no indication that it will allow seamless switching between devices as you can do with Apple’s iPods, for instance. Notifications, however, will finally make third-party watches feasible with iOS devices. 

Apple’s DMA compliance efforts are interesting to watch, as it appears to be doing the bare minimum required, often for what it calls privacy reasons. In some cases, the company is removing features in Europe that are available elsewhere, like iPhone mirroring on Mac — meaning it doesn’t have to implement the same feature on Android devices or PCs.
