Best Tested Portable Air Conditioners for 2025

Having central air is nice, but not every living space comes with that luxury. Sure, you could install something like a window air unit, but that can be a hassle, and you need to make sure your windows are suited for the job. Thankfully, there are also portable air conditioner units. With one of these, you can get your desired temperature without having to install a permanent unit, and they can be much more affordable than central air. You can move them around the house if needed, too. Along wit

The CRPG Renaissance, Part 3: TSR Is Dead

“How do you make a small fortune in tabletop gaming?” runs an old joke. The punchline, of course, is that you come to that market with a large one. The tabletop truly is a brutally challenging place to try to earn money, one which you have to be either wildly deluded or unbelievably passionate to even contemplate entering. Nevertheless, people have been making a go of it there for quite some decades by now. We’ll give them the benefit of the doubt and assume that love rather than mental illnes

20 years working on the same software product

I released version 1 of my table seating planning software, PerfectTablePlan, in February 2005. 20 years ago this month. It was a different world. A world of Windows, shareware and CDs. A lot has changed since then, but PerfectTablePlan is now at version 7 and still going strong. PerfectTablePlan v1 PerfectTablePlan v7 I have released several other products since then, and done some training and consulting, but PerfectTablePlan remains my most successful product. It’s success is due to a lot

MLB is testing robotic umpires in Spring Training, eyes 2026 implementation

Forward-looking: Major League Baseball is testing a computerized system for calling balls and strikes during spring training exhibition games. This Automated Ball-Strike System (ABS), which has been in development for four years in the minor leagues, could aid MLB home plate umpires as early as 2026. The ABS uses a network of cameras installed in stadiums to track each pitch and determine whether it crosses home plate within the strike zone. The current iteration uses Hawk-Eye pose-tracking cam

New leak suggests the iPhone Fold could take inspiration from the Pixel Fold

Oliver Cragg / Android Authority TL;DR Apple’s upcoming book-style foldable phone will apparently have an outer screen that’s “shorter and fatter” than the OPPO Find N. It’s also believed that the inner screen “unfolds like an iPad.” There could be a big difference in size between the inner and outer screens compared to other foldables. Apple has been working on foldable phones for several years now, but we recently heard purported details about a book-style Apple foldable. Now, it looks lik

Oppo's new foldable phone is one of the thinnest I've seen - and I hope OnePlus and Samsung follow suit

Prakhar Khanna/ZDNET The world's thinnest book-style foldable, the Oppo Find N5, is finally here. I've had it for a week, and it has surprised me in more ways than one -- both positively and negatively. At 8.93mm thick when folded, it's closer to slab phones than any other foldable has ever been. But that slimness didn't come without compromises. Judging by the on-paper camera specifications, I expected it to be underwhelming, but it's better than other foldable phones in almost every regard.

Finally, a Windows 11 tablet I'd recommend to both business and professional users

ZDNET's key takeaways The DT Research tablet is built as rugged as it gets, with IP65, MIL-STD-810H, and MIL-STD-461G certifications.

Sweden Investigates New Cable Break Under Baltic Sea

The European Union vowed on Friday to increase security in the Baltic Sea as the Swedish authorities said they were investigating a new cable break, the latest example of damage to underwater infrastructure in the region. The European Commission, the bloc’s executive arm, said it would take new steps to prevent and detect threats to submarine cables, which carry internet traffic and transmit electricity. The severing of several undersea cables in the Baltic Sea in recent months has raised conc

Best Over-Ear Headphones for 2025

Shure Aonic 50 Gen 2: A lot of us liked Shure's original Aonic 50 headphones, but they had pretty middling noise cancellation. Well, the 2nd-gen version addresses that issue -- the noise canceling is much improved -- and Shure has more than doubled the the battery life to around 45 hours (they now have a quick-charge feature) and also shrunk the headphone's carry case a bit, although it's still not that compact. Those upgrades make the Aonic 50 Gen 2 a top noise-canceling headphone. The Aonic 50

Building semiconductor plants in the US takes twice as long, costs twice as much as in Taiwan

The big picture: The U.S. and many Western markets are simply not as efficient as Taiwan in building semiconductor fabrication (fab) operations. According to reports, 18 new fab construction projects are planned for 2025 alone, making it crucial to address these challenges. The West must streamline fab construction processes to catch up with the well-established semiconductor ecosystems of Taiwan and other Asian manufacturing hubs. TSMC encountered significant challenges when it began construct

Apple, Lenovo lead losers in laptop repairability analysis

Apple and Lenovo had the lowest laptop repairability scores in an analysis of recently released devices from consumer advocacy group US Public Interest Research Group (PIRG) Education Fund. While Apple's low marks are partially due the difficulty involved in disassembling MacBooks, Lenovo appears to be withholding information from shoppers deemed critical to right-to-repair legislation and accessibility. The report, US PIRG's fourth annual “Failing the Fix” [PDF], calculated repairability score

Survey shows Elon Musk remains popular among Republicans, but both sides dislike Mark Zuckerberg

In a nutshell: Two of the most influential CEOs in the tech world, Elon Musk and Mark Zuckerberg, have closely aligned themselves with President Donald Trump recently, but how has that affected the nation's view of these billionaires? According to a new survey, more people dislike the pair than like them. However, while Republicans understandably have a more favorable opinion of Musk, it seems almost everyone dislikes Zuckerberg. Between January 27, 2025 and February 2, 2025, The Pew Research C

OPPO’s Find N5 is ready to challenge your foldable expectations

TL;DR OPPO introduces the Find N5, the thinnest book-style foldable around measuring just 8.5mm thick closed. Fully expanded, the phone offers an expansive 8.12-inch internal screen, with OPPO’s least prominent crease to date. While the Find N5 is being made available internationally, those plans don’t include US sales.

The Oppo Find N5 is an impressive, very thin foldable with a giant battery

Oppo is back with a new foldable, and the Find N5 is a technically impressive balance of thinness and power. Skipping over the whole unlucky number four thing (this is technically the fourth iteration of the Find foldable), the company claims its latest book-style foldable is the world’s thinnest at 8.92mm. That's not a lot thicker than a typical flagship phone. Despite that, the Find N5 has a 6.62-inch outer display and an 8.12-inch inner screen which, Oppo says, features multiple durability im
