With Strings Attached

In March 2025, an anonymous buyer purchased the 1715 “Baron Knoop” Stradivarius for $23 million (U.S.), making it the most expensive violin ever sold. (The seller, the American stringed-instrument collector David L. Fulton, had purchased it for a more modest $2.75 million in 1992.) Previous record setters have included the 1721 “Lady Blunt,” which fetched $15.9 million in 2011, and the “Joachim‑Ma,” which went for $11.25 million in February 2025. All three of these models were made by Antonio S

Help us raise $200k to free JavaScript from Oracle

After more than 27,000 people signed our open letter to Oracle about the “JavaScript” trademark, we filed a formal Cancellation Petition with the US Patent and Trademark Office.

Missing your pre-order promo credit on T-Mobile’s Go5G Plus plan? Check your email for the fix

Edgar Cervantes / Android Authority TL;DR T-Mobile customers on the Go5G Plus plan reported missing part of their promotional credits during iPhone 17 pre-orders. Apple has informed affected customers that they will receive the remaining balance via billing once their device trade-in is complete. T-Mobile offers up to $1,100 off when trading in devices for the new iPhone 17 series. Apple launched the iPhone 17 series last week, and it’s got a few Android users tempted to make the switch. For

Seven indie games that will upgrade your downtime this fall

We all know there’s a lot of tech to potentially upgrade in your life, but for those who want to upgrade their downtime with inexpensive, relatively short video games, I have good news. 2025 has already featured a wealth of excellent titles to spend your time with, including ones from smaller and independent developers that you can complete in a few sessions. If you’re looking for a good new game to play (and aren’t already deep into Hollow Knight: Silksong), here are some great options from thi

macOS Tahoe Incompatible with Mac Studio M3 Ultra

If you have a Mac Studio M3 Ultra and want to upgrade it to run macOS 26.0 Tahoe, then I’m afraid you’re going to have wait for Apple to build a new release that will install on your Mac. I’m very grateful to Ken who has tried unsuccessfully to upgrade from 15.7 to 26.0. There are plenty of others reporting exactly the same: the upgrade goes well until towards the end, then aborts and the Mac is restarted back into 15.7. The problem seems to originate from an error in its neural engine driver.

Nothing’s generous Phone 3 loyalty deal puts trade-ins to shame

Ryan Haines / Android Authority TL;DR Nothing is offering $300 off the purchase of a Phone 3. To get the deal you need to submit the IMEI of your Phone 1 or Phone 2. No trade-in is required, but there are some important restrictions to be aware of. You want a brand-new phone, and you’d rather not pay the manufacturer’s full launch price, so what’s a savvy shopper to do? If you’re like a lot of us, you’re always looking around for the best phone trade-in deals, maximizing the value you can ge

Wind turbine blade transportation challenges

The world’s largest airplane, when it’s built, will stretch more than a football field from tip to tail. Sixty percent longer than the biggest existing aircraft, with 12 times as much cargo space as a 747, the behemoth will look like an oil tanker that’s sprouted wings—aeronautical engineering at a preposterous scale. Called WindRunner, and expected by 2030, it’ll haul just one thing: massive wind-turbine blades. In most parts of the world, onshore wind-turbine blades can be built to a length o

Chatbox app is back on the US app store

Hello everyone, I have great news to share: After three months of fighting, our Chatbox app is finally back on the U.S. App Store! 🎉 What happened? In April 2025, another company with an app of the same name filed a dispute with Apple, claiming they held a trademark for the word “Chatbox.” I believe this claim was baseless, because: "Chatbox" is a widely used, generic word across the internet, and their trademark application had already been initially rejected by the USPTO.

How to upgrade your 'incompatible' Windows 10 PC to Windows 11 - for free

After Ukrainian testing, drone-detection radar doubles range with simple software patch

As part of its unprovoked invasion, Russia has been firing massed waves of drones and missiles into Ukraine for years, though the tempo has been raised dramatically in recent months. Barrages of 700-plus drones now regularly attack Ukraine during overnight raids. Russia also appears to have upped the ante dramatically by sending at least 19 drones into Poland last night, some of which were shot down by NATO forces. Many of these drones are Shahed/Geran types built with technology imported from

These are the best AT&T deals you’ll find this September

Edgar Cervantes / Android Authority AT&T takes a different approach than Verizon and T-Mobile when it comes to promotions, upgrades, and special deals. While its rivals often advertise free phones with no trade-in required, AT&T rarely offers devices entirely free up front. That can make it less appealing to switchers, but the trade-off is that existing customers typically get the same deals as new ones. The main caveat is that upgrade offers usually require a higher-end plan, whereas new cust

Hashed sorting is typically faster than hash tables

Hashed sorting is typically faster than hash tables Problem statement: count the unique values in a large array of mostly-unique uint64s. Two standard approaches are: Insert into a hash table and return the number of entries. Sort the array, then count positions that differ from their predecessor. Hash tables win the interview ( O ( n ) O(n) O(n) vs O ( n log ⁡ n ) O(n \log n) O(nlogn)), but sorting is typically faster in a well-tuned implementation. This problem and its variants are the inn

Robinhood embraces copy trading after warning competitors about regulatory risks

What a difference a changing regulatory environment makes. Roughly nine months after suggesting that a young copy trading platform could only operate because it flew “under the radar” of regulators, Robinhood has announced its own entry into the space with “Robinhood Social,” a new feature that will allow users to follow and manually replicate the trades of prominent investors. The move represents a striking about-face for the online brokerage, which has historically been cautious about featur
