I Went Eyes-On With the Aurzen Zip Pro Foldable, Portable Projector. It’s Ready to Shine Your Entertainment Anywhere

A few months ago, I reviewed the Zip Cyber, a cyberpunk-themed pocket projector from Aurzen. It wasn’t very bright, but the trifold design made it extremely pocketable, and the overall appearance was great. 

At IFA, Aurzen debuted the Zip Pro, an updated and upgraded projector with 1080p resolution and twice the brightness. The exterior design is similar, keeping some aspects of the cyberpunk aesthetic (wise, in my opinion) and adding a small touchscreen on the top to aid setup.

While still sporting what Aurzen calls “trifold” (there are two hinges), the Zip Pro is actually slightly larger than the Zip and Zip Cyber at 4.5 by 3.8 by 1.7 inches versus 3.3 by 3.1 by 1 inches. So, it’s nearly three times the total volume and about twice the weight. This is still a remarkably small projector, just less pocketable than the original. It would get swallowed by any backpack. 

Inside, there’s the aforementioned bump up to 1080p, as well as a slightly larger battery. Aurzen says it has 2.5 hours of playtime compared to the Zip’s 1.5 hours. Since it recharges via USB-C, though, you can extend playtime with any decent portable battery pack. So, with the improved performance, the larger size seems a reasonable trade-off.

I got a quick look at the Zip Pro at IFA, and it did seem brighter, as evidenced by far larger image sizes to demo the projector compared to how I’ve seen it demo the Zip. The 200-lumen range makes the Pro far more usable in a wider variety of situations. It competes specs-wise,with the Anker Capsule 3, which was pricey but good. The Zip Pro is more expensive, but most tech is now compared to when the Capsule 3 was launched.

Connectivity

The biggest issue with the Zip Cyber was that it was a challenge to get anything onto it to watch. There’s still no HDMI, but it does have AirLink, Miracast, AirPlay P2P, DLNA and, especially notable since it was missing in the original Zip, Google Cast. You can also connect via USB-C to watch content from your phone.

You can preorder the Zip Pro now, and the MSRP is $630. I’ll be testing out the Zip Pro in my lab soon.

Is flexible work limiting learning opportunities for young employees?

Published

on

David J Finch and Christian Cook of Mount Royal University explore the pros and cons of flexible working and the unforeseen impact for less experienced professionals.

Six years after the Covid-19 pandemic accelerated the shift to remote work, hybrid and remote arrangements have become an established part of the labour market. About one in five Canadians now works remotely some or all of the time.

For many employees, this shift has brought greater autonomy and flexibility. Time previously spent commuting can instead be spent with family or friends. Research has also found that hybrid work can improve employee retention without sacrificing performance.

These benefits, however, may not be experienced equally. Remote and hybrid work may be particularly difficult for employees who are at the beginning of their careers, when much of their professional development still depends on learning from experienced colleagues. Our new report, ‘The End of the Water Cooler: The Hidden Cost of Remote and Hybrid Work on Entry-Level Employees, examines this problem.

Much of how we learn is informal

Think about your first professional job. Much of what you learned probably didn’t come from an employee handbook. You likely learned by observing those around you.

You heard how they approached a problem. Someone pointed out a mistake before it became a larger one. A mentor invited you to a meeting. You asked questions over coffee. You learned who fixed what, who to trust and how things really got done.

These are forms of tacit learning: knowledge that is difficult to codify and is often acquired through observation, experience and social interaction.

The workplace has traditionally provided an environment where this learning occurs alongside formal training. Over time, these interactions help employees develop judgement, confidence, professional networks and an understanding of how their organisations operate.

Advertisement

A study of software engineers illustrates the importance of proximity. Employees who sat near their teammates received 18.3pc more feedback on their code and produced higher-quality code. The gains were concentrated among younger and less tenured employees, who were still building human capital.

There is also evidence that remote work is affecting who gets hired. Employers are hiring fewer young workers for jobs that are easiest to do remotely. An emerging global study found that by 2025, early-career workers made up a substantially smaller share of new hires in highly remote-capable occupations. When researchers tested AI as an explanation, its effect largely disappeared. The remote-work effect remained.

Canadian hiring data shows similar trends, as entry-level professional jobs remain more likely to be on-site, while flexibility grows with seniority.

Those who need mentoring most

Younger workers also appear to place considerable value on opportunities for development and mentorship. Only 23pc of remote-capable Gen Z employees in the United States say they would prefer to work fully remotely, compared with 35pc of older generations.

A 2025 Deloitte survey found half of Gen Z respondents said they wanted a manager who would mentor them, while only 36pc said they were receiving that mentorship.

This creates a potential mismatch between where flexibility is available and where opportunities for learning may be most needed.

But experience must be acquired somewhere. If employers primarily hire workers who already have the skills they need, rather than developing those skills internally, fewer young workers get the opportunity to build experience in the first place.

A problem that is easy to miss

The effects of reduced informal learning can be difficult for organisations to detect.

Advertisement

Employers can readily track completed projects, meetings and other outputs, but they are less likely to measure whether a junior employee has developed professional judgement, built relationships across an organisation or learned how to navigate problems independently.

Research suggests that remote work can change those relationships. A study of more than 61,000 Microsoft employees found that company-wide collaboration became more siloed when employees worked remotely, with employees communicating more within existing networks and less across organisational boundaries.

This is particularly relevant to early-career workers, who have not yet built extensive professional networks. Professional development depends partly on access to people who can provide information, feedback and opportunities.

Design hybrid work around learning

A return to five days in the office is not necessarily the solution. Research suggests that well-designed hybrid work can preserve flexibility without sacrificing performance or advancement.

Advertisement

The question is not whether employees should work remotely, but how organisations should structure remote and in-person work so employees can still develop their skills.

Employers need to design hybrid work around skill development, not attendance. Some forms of learning that once occurred informally may now need to be supported more deliberately. That means identifying which activities benefit from in-person interaction and making sure early-career employees have access to them.

This also puts responsibility on more experienced workers and managers. Mentoring, feedback and exposure to how work is actually done are essential to developing professional judgement and learning organisational norms.

Post-secondary institutions face a similar challenge with work-integrated learning. The value of a placement depends not simply on whether students gain workplace experience, but on the quality of supervision and their access to experienced professionals.

Advertisement

Governments that fund work-integrated learning programmes should therefore place greater emphasis on developmental outcomes new graduates transition to the workforce.

Hybrid work has given many experienced workers more control over their time. But preserving this flexibility cannot come at the cost of compromising the development pathways of the next generation. Whatever our role or level of experience, we all have a part to play in making sure those opportunities continue.

You can now play PS3 games straight from the disc, without owning a PS3

Published

on

Discs Matter: The team behind RPCS3 has announced another significant milestone for the project. The PlayStation 3 emulator is now a step closer to its original goal: perfectly preserving the entire PS3 library for future scholars and gamers alike.

The RPCS3 team recently unveiled a major upgrade for the emulator: PS3 games can now run directly from their original Blu-ray discs, giving retro gaming enthusiasts a new way to use their physical collections. The developers are billing it as a “plug & play” solution, though users will still need to meet a few mandatory hardware requirements to get it working.

Support for direct disc play was made possible by “digant73” and “Megamouse,” the RPCS3 team said. The two developers recently contributed crucial changes to the emulator’s codebase, extending on-disc play support to Linux, FreeBSD, and macOS.

The feature was previously available on Windows alone but is now a “universal” option across all supported operating systems. Install times for on-disc packages have been optimized as well.

RPCS3’s developers say direct disc support should theoretically extend to physical games released as far back as 20 years ago, with no need to rely on external servers. Users will still need to provide a valid decryption key for their specific disc release and boot from a compatible Blu-ray drive; RPCS3 uses the provided key to decrypt the game’s content on the fly.

RPCS3’s quickstart guide includes a handy list of working BD drives, which should be capable of reading a PS3 disc’s file structure, dumping its contents, and booting the game from within the emulator’s UI. Last time I tried, I had no issues extracting and booting an original copy of Demon’s Souls through my “UHD Friendly” Asus Blu-ray burner (BW-16D1HT). Now, I should be able to boot the game straight from the disc as well.

RPCS3’s developers say a compatible BD drive is a “hard” limitation the emulator won’t be able to overcome anytime soon. PS3 games don’t use the standard Blu-ray format, so drives need specific MediaTek chipsets to read the discs properly. Many drives use these chipsets, but not all of them do – hence the “official” compatibility list.

The RPCS3 team is positioning direct disc play as a way to get the most out of personal physical game libraries. The timing sends a pointed message to Sony, which recently confirmed it will stop producing physical discs for new PlayStation games starting in 2028, shifting the platform toward an all-digital future.

Still, direct on-disc play is another major advancement for an emulator tasked with the once “impossible” goal of emulating the PlayStation 3’s Cell multi-core microarchitecture. RPCS3’s compatibility rate recently reached a “playable” state for 75% of the entire PS3 library.

Thousands Of Costco Items Go To B-Stock Auctions Every Week: Here’s How To Bid

Published

on





Who doesn’t love a good Costco deal? Of course, no matter how good the deal is, Costco shoppers know that returns are inevitable. Maybe the clothes you bought don’t fit, or that snack you wanted to try ended up tasting terrible. Whatever your reason, you take the product back, Costco takes your return and gives you a refund, and that’s the end of the story. Or is it?


As it turns out, thousands of those returned items then head to the retailer’s liquidation process. There, Costco sells them in bulk to approved businesses through Costco Wholesale Liquidation Auctions: the company’s official business-to-business liquidation marketplace. Operated through B-Stock, the marketplace sells everything from apparel to electronics, major appliances, furniture, toys, food, and sporting goods. That’s not to suggest it’s all open-box stuff, either. Costco’s B-Stock auctions get their inventory from several sources beyond customer returns, including overstocked merchandise.

Excited? Hold your horses. Costco doesn’t treat these auctions like it does its warehouses. The marketplace is meant for businesses that intend to resell the merchandise. Anyone hoping to bid must apply for approval, which means providing a valid state-specific resale certificate (or, for international buyers, proof of business). Only approved buyers can see and bid on Costco auction lots. Creating an account doesn’t guarantee that you can take part, nor is access one of the many perks of Costco membership.

More about Costco’s Wholesale Liquidation Auctions

Costco’s B-stock auctions can include merchandise that has been tried or used, all screened by Costco’s Returns Depot. Items aren’t tested to see if they work, but are graded visually. Grades are New, Like New, Grade A/B, Grade C/D, and Salvage. For example, new merchandise is in its original packaging; Grade A/B can include returns or unsold products; while Grade C/D can be damaged or have missing parts.

If Costco approves your application, you’ll see lots sold in several sizes, with pallets being a common format. Smaller LTL, or less-than-truckload, auctions typically contain one to 10 pallet spaces, while full truckloads typically contain 11 or more pallet spaces. Smaller quantities can also be sold as boxed small-pack shipments. Buyers should always check the grade before bidding to ensure they know what they’re in for when the pallets arrive. One final point: merchandise bought through one of these Costco Wholesale Liquidation Auctions cannot be resold within five miles of a Costco retail store.

The Helicopter With Radioactive Blades

Published

on

Sometimes you find gold in unexpected places. In this case, it’s from a video about the CH-53 helicopter. The CH-53 Sea Stallion first entered service in 1966. It’s a huge helicopter, capable of lifting immense amounts of weight. All that weight hangs from 6 (or 7 on some models) rotor blades.  The problem was detecting problems with the blades before they grew into a catastrophic failure.

Much like a fixed-wing aircraft wing, the CH-53 rotor blades are designed with a spar as the main structural member.  On early designs, the spar was extruded aluminum. The CH-53D and other variants moved to cold-formed titanium.

All of these blades shared the same problem – detecting tiny cracks in the metal before they grow into blade failure. Detecting cracks turned out to be rather easy. The blades are sealed and pressurized with nitrogen gas. Cracks allow the gas to leak out. A barber pole pressure indicator on the blades allows mechanics to tell at a glance if everything is ok.

That’s all fine and good on the ground, but if a blade begins cracking in the air, the pilots want to know about it immediately. What was needed was something akin to the tire pressure monitoring system on modern cars. A pressure sensor that would turn on a light in the cockpit.  Modern automotive TPMS systems use wireless sensors inside the tire. In the early 60’s though, electronic components were not reliable enough to survive rotating on a helicopter blade. Wiring the sensors through the spinning rotor head using slip rings would be incredibly complex. Expecting wireless electronic components to survive life in a rotorhead would be even more problematic.

Advertisement

The solution turned out to be simple: Throw a little ionizing radiation into the mix. Called IBIS, short for Inflight Blade Monitoring System keeps the CH-53 safe. The magic happens in the same pressure indicator we mentioned earlier. Rather than just a shift from a green to a barber pole indication, the IBIS module also exposes a tiny amount of radioactive Strontium-90.  The Strontium is a beta emitter, meaning its radiation can be detected by a Geiger counter inside the helicopter.  It’s also relatively safe for humans as long as they don’t eat or breathe it in. No batteries, no electronics on the rotor blade. It’s a simple mechanical solution to a difficult problem.

The solution is so elegant it’s still being used today. The newest versions of the CH-53 of fiber optics to detect faults in the newest all-composite blades. The older variants? They’re still going with the nuclear option.

Tech industry’s robotics talent crunch has UW’s new grad program nearly full before day one

Published

on

Robotics jobs in the Pacific Northwest are multiplying faster than universities can train people to fill them. The University of Washington thinks it has an answer — or at least a start.

This fall, UW’s College of Engineering will launch its first robotics graduate programs: a Master of Science in Robotics and a Graduate Certificate in Applied Robotics

The university capped enrollment at 35 students for the inaugural cohort. More than 30 people had already signed up for an information session before applications even opened. It’s an  early signal, engineering leaders say, of pent-up demand from regional powerhouses racing to hire engineers who can operate at the intersection of AI, software and hardware.

Program leaders say that skill set is rooted in a traditional, narrowly focused engineering degree that hasn’t kept pace with the rapid evolution of technology. UW is betting that the fix lies at the intersection of AI and hardware, echoing an industry buzzword called “physical AI.”

“Robotics is no longer confined to a single discipline,” said Xu Chen, a UW engineering professor and director of the Boeing Advanced Research Collaboration, who played a large role in the committee that designed the new programs. “The future will need a wide variety of robotics knowledge, and that’s what we built these programs to deliver.”

Applications opened Sept. 1 and will close Sept. 10, with UW aiming for a roughly one-week turnaround before notifying applicants. For its inaugural year, the university is intentionally keeping things small: 25 seats in the master’s program and 10 in the certificate track, which is designed for working professionals who want robotics training without leaving their jobs.

Chen said the small first cohort is by design, not a limitation. The goal, he emphasized, is to get the fundamentals right before scaling up. He expects the programs to roughly triple in size within three to five years.

“Companies are seeing newer potential in robotics as advanced computing and the wave of AI technology mature,” Chen said. “They see that their workforce will benefit from a modern robotics program, and that need is really what drove this.”

Getting there will take machines, and lots of them. UW is purchasing robots and computing hardware for its initial course offerings while also leaning on industry donations: robots, GPUs, and computing infrastructure among them, according to Chen.

Amazon and Microsoft anchored the effort early; the list of partners has since grown to include NVIDIA, Boeing, Dassault Systèmes — the French software company behind design tools like SolidWorks — and at least one smaller robotics manufacturer.

“The industry board was incredibly supportive from the start,” Chen said. “We’ve had almost a year of continuous meetings and collaboration with them and with representatives across our own engineering departments.”

The broader structure of the program is meant to make it easier for students from different corners of engineering, such as electrical, mechanical and computer science, to land in the same classroom and eventually choose their own path deeper into robotics through electives.

The program is also drawing on UW’s existing research muscle in the region. It taps directly into the Boeing Advanced Research Collaboration, which Chen directs, along with robotics labs inside the Paul G. Allen School of Computer Science & Engineering. That gives students a line into the same research infrastructure that already feeds Seattle’s aerospace and e-commerce giants.

The university’s ambitions extend well past this fall’s launch. Chen said UW has already mapped out longer-term plans for an undergraduate robotics degree and, eventually, a Ph.D. program, with the two new offerings serving as the foundation.

For now, the clearest sign of the program’s ambitions arrived this summer in an unlikely form: a pack of robot dogs let loose on UW’s campus.

“Seattle’s hills make it a uniquely difficult place for robots to move around, which is exactly why it’s a great place to study it,” Chen said.

Both students and faculty got a chance to operate the robots directly, Chen said. It was a hands-on moment that underscored how much more accessible robotics technology has become in just the last few years.

“It was exciting to see the students so happy to see the robots,” Chen said. “That’s the kind of energy we want to build this program around.”

Best Tech Labor Day Sales I’d Shop Myself (2026): Vacuums, Headphones, and More

Published

on

This clip-on speaker packs surprisingly chunky sound for its size. The built-in carabiner means you can easily tote it around while you’re on the go, and the onboard controls are easy to find and operate. This deal is solidly in the middle of what we tend to see; sometimes it falls a bit more in price, but this discount isn’t a bad one.

anker soundcore 2 speaker outside on top of a cooler

This speaker fluctuates in price very often, and it has remained a steadfast budget recommendation in our Bluetooth speaker buying guide. We don’t see it fall below $30 frequently. The sound will not blow you away. But for the price, it’s decent, with great battery life and a very portable water-resistant design.

They’re not the newest Sony headphones we love (the XM6), but at this price, it’s hard not to want to spring for it. This is the lowest price it tends to fall to, but it was selling for almost $50 more just a few days ago. Don’t get me wrong—the XM6 that came out earlier this year are a significant upgrade, but if you want a beautiful-sounding, comfortable, and stylish pair of noise-canceling headphones, the Sony XM5 will still make you very happy. Especially at this price.

Nothing earbuds consistently earn mentions in our buying guides, and the latest iteration is an honorable mention being sold at a very compelling price. The Nothing Ear (3a) are stylish and have solid sound, intuitive controls, and an optional app that’s actually useful. Noise cancellation could be better, but for less than $100 these are still a stellar budget pick.

JMGO’s New Projectors Go Big on Brightness and Refresh Rate. I Had a Look at IFA 2026

Published

on

At the IFA show in Berlin, projector manufacturer JMGO launched its new Iris line. While externally similar to the N3 Ultimate and other models of its gimbal projectors, inside is a new light engine with even greater brightness and the new headline-grabbing feature at the show: a 120Hz refresh rate while running at full 4K resolution.

A 120Hz refresh rate isn’t exactly new in projectors, and definitely not with TVs, but with projectors, that refresh has been historically limited to 1080p. Is this a big deal? Sort of. It’s an interesting technical feat for sure, and shows where projectors can grow. For most people, it’s not likely a huge deal. Yet, a new DLP chip and design like what’s in JMGO’s new projectors is definitely worth having a look at. So I did.

A closeup of the JMGO Iris Ultra Max at IFA 2026.Geoffrey Morrison/CNET

All the refreshes fit to refresh 

I got a brief look at the new Iris projectors at IFA, and there are two models. The Iris Ultra Max has a stated 6,500 lumens, a fully motorized gimbal and a higher native contrast ratio compared to its sibling. The less expensive Iris Ultra has “just” 4,500 lumens and only manual adjustments for the gimbal. Both models have a 0.9-1.7:1 optical zoom as well as horizontal and vertical image shift (separate from the gimbal). They also have a dual iris system to help dial in brightness and improve the dynamic contrast ratio.

I didn’t have any of my test gear with me, and no trade show is an ideal place to judge a product anyway, but the projectors certainly looked bright. JMGO had a side-by-side demo set up running fast-moving and fast-panning 60-frames-per-second content. One projector was running at a refresh rate of 60Hz, the other at 120Hz. The latter did have less blur on some aspects of the image. However, if you’re not watching 60fps content like sports or video games, I’d expect some severe motion-smoothing issues, aka the soap opera effect (this will be the case with any of these higher-refresh projectors). Then again, 120Hz is an even multiple of 24, so theoretically they could dejudder without interpolating frames. We’ll see.

DLP has never had a significant issue with motion blur, so a faster refresh isn’t as big an improvement as it would be with, say, LCD. Reducing LCD motion blur is actually why we have faster refresh rates in TVs to begin with. JMGO says the faster refresh rate can also further minimize DLP’s infamous rainbow effect, where some people notice rainbow trails to certain objects on screen (or when they move their eyes). That could be very helpful for those susceptible to that issue.

A closeup of the JMGO Iris Ultra Max at IFA 2026.Geoffrey Morrison/CNET

I really liked the N3 Ultimate when I reviewed it. It was, at that point anyway, the best gimbal projector. I’m not fully convinced of the need for a fully gimbaled projector for most people. But, with image shift and optical zoom, the N3 can fit in a lot of rooms regardless of how much or little you interact with the gimbal mechanism. And regardless of all that, its performance was excellent. If JMGO can keep the image quality just as high with these new projectors while increasing the already impressive brightness, that will be a very interesting projector. I’ll be getting one to test soon, especially to see if this whole 120Hz thing is worth the hype.

JMGO is expecting the MSRP of the Ultimate Max to be $3,699 and $2,299 for the Ultimate. Both start shipping in mid-October.

Another Rowhammer attack has been detected, and Nvidia workstation GPUs are firmly in the firing line

Published

on


  • GPUThor is the first Rowhammer attack to defeat ECC on Nvidia GPUs and reach a root shell on the host
  • It affects four Ampere workstation cards with GDDR6 memory, the RTX A4000, A4500, A5000 and A6000
  • Non-uniform hammering, enabled by defeating GPU memory coalescing and finding that Target Row Refresh (TRR) mitigations fire once every 72 refresh intervals, delivers effectively 6.6 times the hammering intensity of prior attacks

Four researchers at the University of Toronto have disclosed GPUThor, a Rowhammer technique that breaks the error correction Nvidia has spent the past year recommending as the defense against exactly this class of attack.

Chris S. Lin, Joyce Qu, Aditya Rajeev and Gururaj Saileshwar are expected to present the paper outlining their approach and subsequent findings at ACM CCS 2026.

What Does Candela Mean On A Flashlight (And Why Brightness Isn’t Everything)?

Published

on





While flashlights seem like simple tech, there are a number of fairly technical terms associated with them, like COB and candela. While many flashlights are primarily evaluated in terms of lumen output, candela is also an important metric. Candela is the measurement that tells you how intense a flashlight’s beam is in a specific direction, not how much total light the flashlight produces. It measures the brightness of a light at 100 feet from the source, and unlike lumens, incorporates factors like reflector size and whether the lens in front of a bulb dims the light. In simple terms, lumens tell you the overall amount of light, while candela tells you how tightly that light is focused and how far it can reach.

That distinction matters because buying a flashlight with a high lumen rating doesn’t automatically give you a better long-distance light. A wide flood beam can look very bright up close, but still have relatively low candela, while a tightly focused beam can reach much farther even with fewer lumens. Candela is especially useful when you’re comparing flashlights that look similar on paper, but behave very differently in the real world. Two lights can advertise the same lumen output and still produce very different beams based on the aforementioned reflectors and lenses, as well as LED placement and optic design.

Why it matters

Brightness is only the total amount of visible light a flashlight produces. It doesn’t give you a sense of where that light goes or how long it stays bright. It also doesn’t indicate how well you can see colors, detail, or whether the light is practical for the job.

Candela, meanwhile, helps you understand whether a flashlight, including the most powerful flashlights available on Amazon, is better for close-up tasks or for lighting up objects at a distance. A high-candela light is usually better for spotting trail markers, looking across a field, or cutting through fog and smoke, while a lower-candela light is better when you want a broad, even wash of light.

You’ll also see candela discussed alongside “throw,” which is basically beam distance. Flashlight testers often use candela to estimate how far the brightest part of the beam will reach, and the beam’s shape matters as much as raw output. 

Advertisement

In other words, candela is the number to watch when you care about reach, not just brightness. That’s why some flashlight buyers prefer a high-candela model for outdoor or tactical use, while others choose a lower-candela light for camping, household tasks, or general carry. Once you understand what candela is, flashlight specs stop being just a list of numbers and become key info that tells you what the light will actually do in practice.
