Dev who gave HashiCorp its name returns with a faster terminal multiplexer

Published

DEVOPS

Persistent sessions could be just the beginning

HashiCorp cofounder Mitchell Hashimoto has launched a new startup to build a server-side terminal multiplexer that allows programmers to switch between multiple persistent work sessions.

Superlogical promises its terminal multiplexer will be faster and keep better track of user jobs. And it could be instrumental to building durable agentic layers into future systems.

The problem with traditional multiplexers – such as tmux, Zellij and GNU Screen – is that they are all too slow, explained Superlogical cofounder Mitchell Hashimoto in a video posted on X. They duplicate everything the user types and have to constantly reconcile local and remote states. Even slapping a modern terminal such as Kitty, Alacritty or Ghostty in front of a multiplexer won’t do much to speed ops.  

“A terminal multiplexer may sound like a narrow place to start a company,” the company admits on its website. But the lowly terminal is the common denominator across today’s developers, agents, tools, and infrastructure. 

For Hashimoto, today’s computer architecture is missing a fundamental primitive: a stateful session for the work itself. With work spanning machines and users, a task needs its own space for context, data, and history.  

Turning a terminal into a business

The technology builds on a project called Ghostty, a modern terminal emulator that Hashimoto began developing while he was still at HashiCorp, the company he co-founded.

One of the oldest tools in the computer stack, a terminal emulator is simply a text-based window on the screen where developers can enter commands for the computer, either locally or remotely. Taking its name from the physical terminals of a bygone era, the terminal is where one finds the “command line interface” or CLI. 

The terminal geeks quickly and widely adopted the GPU-driven Ghostty for both its lightning-fast performance and wealth of features – two qualities other emulators rarely possessed in tandem.

Hashimoto also extracted the core Ghostty engine into its own software library, libghostty, for others to build upon. Superlogical plans to eliminate that client/server duplication by building on libghostty.

In Superlogical’s approach, the client sends terminal input to the server, much like an SSH session, while the server maintains the persistent session state. This lets users disconnect and return later, while a smart client handles rendering and scrolling locally rather than waiting for a network round trip.

“It does require that every connecting client be a very smart, high-functioning, compliant client,” such as one built on libghostty, Hashimoto said. But this approach sounds better than dispatching streams of raw ASCII hither and yon.

Beyond describing the headaches of multiplexers in his introductory video, Hashimoto didn’t divulge much more about the newly founded company’s plans, but the mission will no doubt involve expanding on the concept of managing work sessions in a standardized and scalable way. 

Gergely Orosz, author of the popular Pragmatic Engineer Substack, speculated on X that the Superlogical team would “be building an AI-native ‘agentic operating system’ that sits a level above OSes.” ®

OpenAI reportedly finds evidence that more of its agents ran amok

Published

on

Much has been made of the incident in which one of OpenAI’s agents broke out of its sandboxed test environment and proceeded to hack the AI hosting platform Hugging Face. OpenAI has since launched an investigation into how the incident occurred, which is still ongoing.

Now, anonymous sources have told Reuters that more of OpenAI’s agents are believed to have escaped their sandboxes. However, one source downplayed the severity, saying that with those escapes, the agents didn’t appear to leave OpenAI’s network to hack into another company’s. TechCrunch reached out to OpenAI for more information.

AI programs acting in bizarre ways has apparently become a weird, almost bragging point for companies. The same week, Anthropic also announced that it had discovered not one, but three instances in which its agents had escaped test environments and hacked other organizations.

AI companies have also been accused of using such incidents for marketing purposes — as they generate considerable attention and may underscore how powerful the companies’ products are. The flip side of that is that these disclosures are also ramping up discussions of government regulations.

Snapchat’s Spotlight algorithm now favors human-made videos over AI-generated ones

Published

on

If you’ve been uploading fully AI-generated videos on Snapchat in hopes of earning rewards, it might be time to rethink your strategy. Snapchat has announced changes to Spotlight that prioritize authentic, original creativity over content created entirely by artificial intelligence. The company says its recommendation system will now favor videos made by real creators, while fully AI-generated submissions will no longer qualify for monetization.

So what’s changing on Spotlight?

Starting this month, fully AI-generated videos are no longer eligible for recommendation on Spotlight, Snapchat’s public feed for vertical content. That rule applies even if AI use is disclosed, since Snapchat’s updated guidelines state that human-made content gets prioritized over AI content regardless of transparency labels.

Snapchat isn’t cutting AI out completely, though. Videos edited or enhanced using Snapchat’s own AI creative tools remain eligible, and those will carry visible indicators showing AI played a role. Snap says unique Spotlight contributors are up more than 120% from last year, a number it points to as proof people are already choosing to create original content.

Snapchat joins the growing pushback against AI slop on social media

The rise of AI slop has become a growing challenge across social media platforms. They are quick to produce, easy to flood the recommendation feeds, and often crowd out original creators. Snapchat says its latest changes are meant to improve the viewing experience while ensuring creators who invest time and effort have a better chance of reaching an audience.

Snapchat joins a growing list of platforms tightening their AI policies recently. LinkedIn rolled out a button letting users flag posts as AI slop, and YouTube updated its monetization rules to block payouts on generic or template-based AI content. Meta pulled a controversial Instagram AI photo tool after backlash too, though its CEO has continued pushing for more AI driven personalized content elsewhere.

With the latest move, Snapchat is betting that authenticity, not automation, is what keeps pulling people back to the platform.

Joni Mitchell Court and Spark Rhino High Fidelity Vinyl Review: Kevin Gray’s AAA Remaster Delivers

Published

on

Joni Mitchell’s 1974 smash hit Court and Spark has occupied a prominent place in the audiophile universe almost since the day it was released. A fantastic album from start to finish, it features iconic tracks such as “Free Man in Paris” and the Top 10 single “Help Me.”

The album earned four Grammy nominations and won Best Arrangement Accompanying Vocalist(s) for “Down to You.” It reached No. 2 in the United States and No. 1 in Mitchell’s native Canada, eventually achieving double-platinum sales of more than two million copies. Frequently included on lists of the greatest albums of all time, Court and Spark was inducted into the Grammy Hall of Fame in 2004.

Back in the day, this spectacular recording was a go-to demo disc for audio enthusiasts and mass-market retailers showcasing the era’s popular high-end stereo components. The opening 30 seconds of “Help Me,” featuring John Guerin’s still-stunning, drumhead-bending tom-tom run, became a particularly popular test for new loudspeakers.

joni-mitchell-court-spark-rhino-high-fidelity-lp-label

While Court and Spark has been reissued countless times over the years, audiophile-oriented vinyl editions have been surprisingly scarce. A search of Discogs suggests that, after the 1980 Nautilus Half-Speed Mastered “SuperDisc” edition, another major audiophile pressing did not appear until Mobile Fidelity’s 2024 Original Master Recording UltraDisc One-Step 180-gram, 45 RPM 2LP box set ($104.86 on Amazon) which I have yet to hear.

joni-mitchell-court-spark-mofi

For those of us who love this album but would prefer a more affordable single-disc edition, the new Rhino High Fidelity pressing may be just the ticket. Available exclusively through Rhino’s website, it sells for $39.98.

Featuring all-analog mastering, with lacquers cut by the esteemed Kevin Gray at Cohearent Audio, the new edition was pressed at Germany’s Optimal Media, one of the world’s most respected vinyl manufacturing facilities.

joni-mitchell-court-spark-rhino-high-fidelity-numbering

So, how does it sound? In a word: fantastic. It is all in the details. Instrumental separation is more precise, while the wider soundstage feels natural rather than exaggerated.

On “Trouble Child,” the buzzing resonance of Joni’s acoustic guitar strings sounds bigger and rounder. Drummer John Guerin’s widely panned rimshots on Joni’s cover of Lambert, Hendricks & Ross’s “Twisted” are more distinct on this new Rhino edition, while her rich, double-tracked, open-tuned acoustic guitars on “People’s Parties” sound simply gorgeous.

This edition is far better than most stock original pressings, and for good reason. The mid-1970s oil crisis frequently resulted in noisier vinyl as manufacturers cut corners, with petroleum serving as a key raw material in vinyl production. Quality control on Warner, Elektra and Asylum releases could also be inconsistent, making annoyingly off-center pressings fairly common—as is the case with my current original copy.

The new Rhino edition also easily bests my Nautilus SuperDisc pressing, presenting the music with greater warmth and less compression. By comparison, the Nautilus sounds thin and overly bright.

joni-mitchell-court-spark-insert

My only quibble with the new edition is that Rhino did not recreate the soft matte finish, bas-relief-style raised lettering and textured presentation of Joni’s cover painting found on original copies. Instead, it opted for a glossy, laminated flat-art approach.

It is a minor detail, I realize, but one that will keep my original pressing in the collection alongside this new edition. The pristine Nautilus copy, however, can start packing.

Ireland set to see major solar eclipse covering 96pc of sun

Published

on

Several gatherings are scheduled across the country for viewers to enjoy the phenomenon.

Space enthusiasts are abuzz for August as they wait for a once-in-a-lifetime solar eclipse that will nearly swallow the entire sun.

The eclipse is set to start at around 6.15pm on 12 August, reach its maximum an hour later and end at around 8.08pm. It will be the largest eclipse visible from Ireland until 2090 and will offer viewers in Europe the opportunity to witness the eclipse as the sun sets.

The total solar eclipse will sweep across Greenland, Iceland, northern Russia, the Atlantic Ocean, Spain and a portion of Portugal. Across the world, parts of northern US, much of Canada, much of Europe and north-western Africa will also witness the phenomenon.

In Ireland, Cork is best-positioned to watch the eclipse, with 96pc of the sun expected to be covered at the eclipse’s peak. Around 94pc of the sun will be covered in Dublin and 93pc in Belfast.

Several gatherings are scheduled across the country for viewers to go enjoy the astronomical phenomenon, including Maynooth University, which is organising a watch party alongside a live planetarium show, arts and crafts activities for kids, and short talks.

Munster Technological University (MTU)’s Blackrock Castle Observatory is providing 6,500 free solar eclipse glasses through select locations across Cork.

Astronomy experts from the Observatory have advised that anyone looking directly at the sun should wear certified ISO 12312-2 eclipse glasses. Ordinary sunglasses do not promise adequate protection, they warned. Cameras, binoculars and telescopes require correctly fitted solar filters, while pinhole projectors offer a safe, indirect alternative.

“Cork’s position in the south-west means it is Ireland’s best-positioned major city for the solar eclipse, and Ireland’s natural ‘Eclipse Capital’,” said Dr Niall Smith, the head of research at MTU and head of MTU Blackrock Castle Observatory.

“It will be a spectacular moment and a rare opportunity for people across Cork to experience a major astronomical event together.

“Safety must be at the centre of everyone’s plans. There will be no point during the eclipse when it is safe to look directly at the sun without certified eclipse glasses or another approved viewing method.”

MTU Blackrock Castle Observatory is organising free public activities that will also take place at the observatory – as well as Tramore Valley Park and Bell’s Field in Cork – with members of the public getting the opportunity to meet astronomy experts, learn about safe eclipse viewing, and enjoy music and family activities. Visitors can also enjoy solar eclipse lino-printing and pinhole-projector activities planned for the gathering Tramore Valley Park and Bell’s Field.

Netflix pays a ridiculous amount to share The Walking Dead

Published

on

Netflix is reportedly spending $500 million to keep The Walking Dead on its platform. It does so despite no longer holding exclusive streaming rights to the franchise.

The new five-year licensing agreement will see the zombie saga shared between Netflix and AMC+ from 2027. This marks a rare move for the streaming giant.

According to AMC, the deal covers 371 episodes across the original The Walking Dead series and six spin-offs. These include Fear the Walking Dead, The Walking Dead: Daryl Dixon, Dead City, The Ones Who Live, World Beyond and Tales of The Walking Dead.

The agreement also significantly expands Netflix’s reach beyond the US. Alongside renewing its domestic rights, the streamer has secured international distribution in markets including the UK, Italy and Australia. This will give subscribers in those regions access to the full franchise from 2027.

Perhaps the more surprising part of the deal is that AMC+ will also stream the original series for the first time. Previously, Netflix has held exclusive streaming rights to The Walking Dead since 2011, despite AMC Studios producing the franchise. However, under the new arrangement, both services will carry the flagship show simultaneously.

For Netflix, paying half a billion dollars for a non-exclusive licence is an unusual strategy. The company has historically favoured exclusive rights to high-profile content, making this shared agreement stand out. However, the numbers suggest The Walking Dead continues to perform strongly on the platform. This is more than a decade after it first arrived.

“Audiences have discovered and loved The Walking Dead on Netflix for nearly 15 years and the show continues to attract new fans,” said Lori Conkling, Netflix’s Vice President of Licensing.

AMC also believes the expanded partnership will help introduce the franchise to new audiences. “This deal creates a global destination for this universe – all shows, all episodes – making the franchise more accessible than ever to fans around the world,” said AMC CEO Kristin Dolan.

The agreement highlights Netflix’s continued willingness to invest heavily in proven franchises. While the streamer has increasingly focused on original programming, it has also spent heavily on established hits such as Friends and The Office. In addition, with The Walking Dead continuing to attract viewers years after its debut, Netflix appears to have decided the franchise remains worth a sizeable investment. This is the case even if it now has to share it.

OpenAI’s rogue AI agent: Can the internet survive?

Published

on

The internet may no longer be solely the domain of humans. Last week, OpenAI disclosed an “unprecedented cyberincident”: An experimental AI agent successfully hacked its way into the open internet.

Specifically, the agent was assigned a task; in order to complete it, the agent broke out of an isolated research environment and hacked into a third-party platform called Hugging Face. It’s a move that many experts deemed inevitable, given the speed and scale of advances in AI technology — and it raises serious questions about AI safety.

But for Konstantinos Komaitis, a senior fellow with the Democracy and Tech Initiative at the Atlantic Council, it wasn’t the unexpected behavior of the AI that was significant. It was what that behavior could mean for the internet’s fundamental, decentralized infrastructure and whether it would spur calls to build new barriers against autonomous AI agents.

Komaitis argues that such barriers are not the solution, however. He spoke with Today, Explained co-host Sean Rameswaram about why an open internet is actually key to combating AI cybersecurity threats.

Advertisement

Below is an excerpt of the conversation, edited for length and clarity. There’s much more in the full podcast, so listen to Today, Explained wherever you get podcasts, including Apple Podcasts, Pandora, and Spotify.

So most people see that this happens and they think, “Oh no, AI went rogue. How long before it kills me?” You see that this happens and you start thinking about infrastructure. Tell us more about why you were thinking about infrastructure in light of this AI agent breaking containment.

The internet was never designed with full security in mind, right?

When you’re creating a decentralized system, you cannot possibly foresee every security or vulnerability that might come up. But because you have a system that is based on building blocks, you have the extraordinary capability of actually addressing security issues as they come up through those building blocks without breaking the whole system down.

Advertisement

And of course, the other thing that this does is that it pushes you towards collaboration, because when you have so many building blocks, you cannot possibly possess all the knowledge for each building block. So you’re bringing literally everyone to try to address these problems.

Take the internet, for instance: We have spent decades addressing those vulnerabilities and developing mechanisms to authenticate users and devices, encrypt communications, mitigate distributed attacks, coordinate incident response, and of course share threat intelligence.

Now, what is new with agentic AI is not that simply the malware is better or the phishing attacks are more sophisticated. It’s the emergence of systems that can actually discover vulnerabilities across thousands of systems. They can reason about alternative paths to an objective. They can adapt when they’re blocked. They can chain together legitimate internet services in unexpected ways. Then they do that while they’re operating continuously at machine speed. And this is really at a scale that the internet is not ready to necessarily cope with.

Effectively, the internet’s openness becomes both a strength and a vulnerability. So the internet was optimized for interoperability, and AI now is optimized for exploiting that interoperability.

Advertisement

And what scares you the most about that? What do you think is most vulnerable to threats?

The fact that we do not have the appropriate mechanisms and institutions to be able to deal with that. I come from the internet world. I’ve spent 20 years of my career defending the open internet and discussing it in international fora. And one of the things that a lot of people underestimate about the internet is how valuable trust is as a property within the system.

We are talking about networks that exchange data literally based on trust. So what really concerns me right now is that in many ways, we are asking 21st-century AI systems to operate on 20th-century assumptions about trust. And unless we figure that out and we realize it, we will continue having these problems. And of course, the knee-jerk reactions that are coming with this, which are, “Let’s fragment the internet, let’s restrict it, let’s restrict access, let’s take control over it.” That is never the solution.

What do you see as the solution?

Advertisement

Effectively, we need to build institutions that are trusted and are able to cope with those incidents as they happen. Because right now you have OpenAI and you have Hugging Face telling everyone, “Don’t worry, we’ve got this.” And we don’t know; they might have this. But at the same time, I cannot help but wonder. And many, many other people have wondered whether, actually, this is very good PR for these companies and especially for OpenAI.

OpenAI just went to the world saying, “We have developed one of the most powerful LLMs, and we realized that it behaved the way it behaved, but don’t worry, we are going to fix this.” And in this current climate and in this current timing, I am not sure that this is enough. You need institutions that are much more transparent, much more accountable, and much more collaborative across the board.

You want institutions to step up and essentially serve as a watchdog. Help us understand which institutions, because in the United States, famously, our government has done very little to regulate tech.

First of all, we need to stop thinking of institutions as necessarily government-affiliated, right? Or that they are the outcomes of government initiatives. There can be in collaboration with governments, but one of the things that the internet has taught us is that institutions that are built through a bottom-up coordinated process have the tendency of actually being more agile and able to deliver some of those things that we’re talking about.

Advertisement

So take, for instance, again, open standards. The internet’s open standards are not created by any agency, government or private. It’s created by institutions where engineers from all across the board and all over the world gather together and create those standards.

That’s reminding me of the original design of OpenAI to be this not-for-profit company that had everyone’s best intentions in mind, that could do something idealistic and moral and ethical because all of the profit-minded companies weren’t going to. And now look at OpenAI. Their not-for-profit arm is an afterthought, and they’re chasing profits.

Do you think it’s practical to leave this to institutions? Because what we’ve seen so far is that institutions bend toward capitalism.

It really depends on how you build the institution, right? It really depends on what sort of guardrails and checks and balances you have around it. In order to build an institution, you need to really know what you want to achieve. You need to have a north star.

Advertisement

One of the reasons the internet worked was because everybody disagreed, but they agreed on the common shared goal, which was to connect people across the world. For AI, we still do not have that northern star. And once we get it, that’s when you start the building of those institutions in order to facilitate this and bring everyone together.

For me, it is very important for everyone to understand that keeping an open internet is really more important than ever, especially as AI agents become increasingly capable. Because it is tempting to think that the answer to new AI risk is literally ‘build more barriers.’ But the internet’s greatest strength has always been its openness. So the challenge today is not that the internet is too open; it’s that its trust architecture was designed for a world in which humans or software directly controlled by humans were the primary actors.

Now, it’s being challenged by this agentic AI that introduces a new type of participant — systems that can reason and plan and act with limited human oversight. So we need to evolve our understanding of trust and what it means online. And that will require a lot of work because, as you know very well, Sean, it’s very difficult to build trust, but you can break it within seconds.

Sony’s Plan to Kill Physical PlayStation Discs Faces Gamer Backlash

Published

on

The age of the physical disc is ending on the Sony PlayStation. Despite backlash from gamers, the company intends to continue with its plans to end PlayStation disc sales as of January 2028.

“Following this date, new games will be available on PlayStation Store and at retailers in digital formats only. This transition has no impact on games that already released, or will be releasing, prior to January 2028 in disc format,” Sony said in a PlayStation blog post on July 1 . The post said the change is driven by consumer trends and a general preference for digital media.

Many PlayStation gamers clearly felt otherwise, with some players calling for a worldwide boycott of Sony platforms beginning in August. The PSBlackout urges gamers to keep their systems powered off for the entire week of Aug. 23. A petition on Change.org called “Don’t Kill the Disc” has also racked up over 350,000 verified signatures so far.

The backlash prompted Sony to respond to gamers in a Q&A session with shareholders, but the company isn’t changing its decision. Sony CFO Lin Tao said that the brand intends to continue moving forward with its plan to end physical disc sales and that the company doesn’t believe the backlash will negatively affect sales, though Tao noted the company will proceed “cautiously” with its plans.

Tao also said that the company is deciding how to address feedback from gamers unhappy with the decision. She said that Sony wants to consider the emotions of upset players, since the games are “connected to people’s fond memories.”

She also said the company might take measures in the future to lessen the blow, without specifying what those measures might be, and said that Sony wanted to engage with gamers in the future digital ecosystem.

A Sony representative did not immediately respond to a request for comment.

Currently, the PlayStation 5 Slim Disc is the only model that comes with a built-in disc drive for physical games. However, you can still buy a separate disc drive for the PS5 Digital Edition and PS5 Pro console.

Some players plan to boycott Sony platforms to protest the loss of physical games.SOPA Images/Getty Images

Unless the August boycott significantly affects Sony’s bottom line, the company is unlikely to back down on this decision. Discs, after all, can be resold, creating a secondary market from which the company doesn’t profit. All digital sales are controlled solely by the company, no matter how old the title is. This is also likely to affect resale platforms like GameStop and eBay, where gamers can usually get used titles at significant discounts.

As many commentators point out, digital titles grant a revocable license for the game, not ownership. So it’s technically possible for Sony to pull a game you’ve paid for and downloaded onto your system, though it’s rare that a company does this if there isn’t a copyright or licensing issue.

This is a transition that PC gamers made ages ago, with purely digital storefronts like Steam, Epic, GOG and others now being the most common ways PC gamers play games. These days, you really need to go out of your way to include an optical drive in your PC build since it’s not a default option. I’ve also found that many of my older disc games, like Age of Empires 3 and the first Rome: Total War, aren’t compatible with Windows 11, and you can’t even install or run them properly.

IGN reported that Project Helix, Xbox’s next console, will not have a disc drive and that Microsoft is exploring ways to digitize physical games. That may leave Nintendo as the sole company to continue supporting physical game media for the foreseeable future, in the form of cartridges for the Switch 2, which can also play games made for the original Switch.

Best Robot Vacuum of 2026: Shark, Eufy

Published

on

I’ve recently introduced a few friends to the power of a great robot vacuum. One of my friends calls hers a marriage saver, while the other was both thrilled and horrified by how many stains the vacuum’s AI found on her floors. Personally, my robot vacuums keep me from wanting to set the litter box on fire, since my cat is on a mission to create his own navigational trail of litter through my home.

The best robot vacuums these days aren’t just vacuuming your floors, nor are they blindly bumping around your house like they used to. These gadgets are mopping, scrubbing away stains, lifting themselves off obstacles, and even reminding you to clean the dirtier areas in your home more frequently. A good robot vacuum can cost a pretty penny, but it doesn’t have to, depending on what you’re looking for. Curious about what’s the best model for you? I’ve been testing every new robot vacuum I can in my three-story home filled with three adults, a preschooler, and a cat who’s on a mission to get litter all over the house.

Here are the best robot vacuum cleaners I’ve tried this year, and everything we really liked from recent years. Looking for more vacuum ideas? Don’t miss our guides to the Best Dyson Vacuums, Best Cordless Vacuums, Best Vacuums for Pet Hair, Best Carpet Cleaners, and Best Vacuums.

Updated July 2026: I’ve added details about the new FCC ban that will affect future robot vacuums.

What’s a Robot Vacuum?

A robot vacuum is an automated vacuum, usually shaped like a round disc, that moves around your house to vacuum (and mop, as many models these days include mopping) on your behalf. You might’ve heard some refer to these devices as “Roombas,” which is the brand that made the concept popular, but today just about every cleaning brand—from high-end Dyson to affordable Bissell—makes some kind of robot vacuum. They come with either a charging station or a larger docking station that can self-empty.

Can You Use Robot Vacuums on All Kinds of Floors?

You can, especially since there are so many mopping models now to better clean hard flooring. You can use these devices on anything from hardwood to LVP and tile, though I wouldn’t recommend leaving smaller rugs out for these autonomous gadgets to get stuck on. Large, set rugs are fine, but bathroom and kitchen mats or any thin, easily moved rugs should be cleared out of the way and put in the wash instead of vacuumed by your robot vac.

What Will Your Robot Vacuum Need?

There are a few things most robot vacuums will need to work properly:

  • Space around the base station. Many robot vacuum manuals recommend at least a foot of clearance on three of the four sides of the vacuum’s base station to ensure it has room to return home.
  • A good Wi-Fi signal. If your robot vacuum connects to Wi-Fi, as many do these days for app control and software updates, it’ll need a strong connection wherever it’s placed. Most of them can only connect to the 2.4 GHz wireless band, so make sure you have that (and choose only that band when you’re setting up if your Wi-Fi shows those bands separately). Confused? Check out our guide to setting up your smart home.
  • Regular maintenance. It might be a robot, but it can’t take care of itself. See below for my tips for basic robot vacuum maintenance, and make sure to read your vacuum’s manual to know what your specific model requires.

How Often to Maintain Your Robot Vacuum

Taking good care of your robot vacuum will help it last. Here’s the debris-removal process you should follow for each robot vacuum style.

Advertisement
  • If it has a charger-only base: This means the debris is stored inside the vacuum. You’ll likely want to empty it after each use. If your vacuum has a fill line you can watch, you can empty it when it reaches that line, but after each use is really best practice.
  • If it has a self-emptying docking station: Each manufacturer will have different advice about when a self-emptying station needs to be emptied, but it’s usually between 30 and 60 days, depending on design and use. If you run your vacuum daily and have a lot of debris, like pet hair, you might need to aim for 30 days or less.
  • If it has water tanks: Dirty-water tanks should be cleaned after each mopping run of your vacuum. Clean water can stay filled in the station.

Make sure to review your robot vacuum’s manual for any other steps the manufacturer recommends you take regularly to keep the vacuum running for as long as possible. Many brands also have replacement parts, so you can swap out individual pieces like brushes without needing an entirely new vacuum.

Did Robot Vacuums Just Get Banned?

The Federal Communications Commission, or FCC, announced in late July that foreign-produced advanced robotic devices will now be included on the FCC’s Covered List. That list includes communications equipment and services that are deemed to pose an unacceptable risk to the national security of the United States, and as of this week, that includes robot vacuums (and similar devices like robotic pool cleaners and lawn mowers). While it won’t ban any models already on the market that have FCC approval, we’ll likely see a huge decline in available new models after this year. Models made in the US will be fine, but future vacuums from popular brands like Dreame, Eufy, Roborock, and more will be affected.

This comes from an interagency body in the White House executive branch called the National Security Determination, which determined that automated robotic devices are a security risk due to the data they collect, which could be used for surveillance and be remotely commandeered by “malign actors.” While the initial documentation describes humanoid robots and a recent case of a humanoid robot’s cybersecurity vulnerability to be remotely taken over, the official description of these robot devices will include robot vacuums and any devices meeting the following criteria:

Why Do Semi-Trucks Need Three Different Types Of Tires?

Published

When a semi-truck barrels past you on the highway, it might be hard to tell that it’s doing so with three different types of tires on its wheels. It might seem strange, but try to take a look next time you’re up close and personal with one. Most long-haul tractor-trailers rely on a combination of steer tires, drive tires, and trailer tires. It’s because each axle performs a different job, and that necessitates a different tire for each. Semi-truck tires are nothing like regular tires, either, and each of the three designs features special construction and tread patterns tailored to its location on the semi.

Depending on where it’s mounted, a tire might need to control the truck’s direction, transfer engine power to the road, or support the thousands of pounds of cargo in back. Using the proper tire for its intended position also improves handling, mileage, fuel efficiency, and overall performance. The opposite is also true: Because each tire is designed for a specific purpose, mixing types across different axle positions can make a truck less efficient. Let’s break down the specific needs for the three tires used on the assortment of wheels that give eighteen-wheelers their name.

A look at the three types of tires semi-trucks use

Steer tires go on the front axle. They’re responsible for guiding the 80,000-pound vehicle through turns, lane changes, highway curves, and other steering tasks. Steer tires will often use a ribbed tread pattern that channels water away from the contact patch. That helps them maintain steering precision and resist hydroplaning in the wet. Industry guidance is to replace these after roughly 100,000 to 150,000 miles, depending on operating conditions and maintenance. 

If steer tires determine where a semi-truck goes, drive tires make sure it gets there. They’re mounted on the powered drive axles and help convert engine torque into forward movement. Their treads typically feature deeper, lug-style patterns that maximize grip across different road surfaces. That added traction isn’t just important during acceleration, but also comes into play when climbing grades, braking, or traveling through inclement weather. Depending on service conditions, fleets might go for approximately 350,000 to 500,000 miles before replacing these tires.

Then there are trailer tires. Unlike drive tires, they don’t receive any engine power. And unlike steer tires, they aren’t responsible for directing the truck, either. Instead, they need to withstand not just the weight of cargo but also the forces acting upon them when trailers pivot through turns. Some models also incorporate reinforced sidewalls for improved endurance and damage resistance. These are generally replaced after 200,000 to 325,000 miles, depending on usage.
