"An engineer got curious about how his iLife A11 smart vacuum worked and monitored the network traffic coming from the device," writes Tom's Hardware.

"That's when he noticed it was constantly sending logs and telemetry data to the manufacturer — something he hadn't consented to." The user, Harishankar, decided to block the telemetry servers' IP addresses on his network, while keeping the firmware and OTA servers open. While his smart gadget worked for a while, it just refused to turn on soon after... He sent it to the service center multiple times, wherein the technicians would turn it on and see nothing wrong with the vacuum. When they returned it to him, it would work for a few days and then fail to boot again... [H]e decided to disassemble the thing to determine what killed it and to see if he could get it working again...

[He discovered] a GD32F103 microcontroller to manage its plethora of sensors, including Lidar, gyroscopes, and encoders. He created PCB connectors and wrote Python scripts to control them with a computer, presumably to test each piece individually and identify what went wrong. From there, he built a Raspberry Pi joystick to manually drive the vacuum, proving that there was nothing wrong with the hardware. From this, he looked at its software and operating system, and that's where he discovered the dark truth: his smart vacuum was a security nightmare and a black hole for his personal data.

First of all, it's Android Debug Bridge, which gives him full root access to the vacuum, wasn't protected by any kind of password or encryption. The manufacturer added a makeshift security protocol by omitting a crucial file, which caused it to disconnect soon after booting, but Harishankar easily bypassed it. He then discovered that it used Google Cartographer to build a live 3D map of his home. This isn't unusual, by far. After all, it's a smart vacuum, and it needs that data to navigate around his home. However, the concerning thing is that it was sending off all this data to the manufacturer's server. It makes sense for the device to send this data to the manufacturer, as its onboard SoC is nowhere near powerful enough to process all that data. However, it seems that iLife did not clear this with its customers.

Furthermore, the engineer made one disturbing discovery — deep in the logs of his non-functioning smart vacuum, he found a command with a timestamp that matched exactly the time the gadget stopped working. This was clearly a kill command, and after he reversed it and rebooted the appliance, it roared back to life.

Off the southwest cost of Italy, a remotely operated submarine made "a significant and rare discovery," reports the Independent — a vast white coral reef that was 80 metres tall (262 feet) and 2 metres wide (6.56 feet) "containing important species and fossil traces." Often dubbed the "rainforests of the sea", coral reefs are of immense scientific interest due to their status as some of the planet's richest marine ecosystems, harbouring millions of species. They play a crucial role in sustaining marine life but are currently under considerable threat...

hese impressive formations are composed of deep-water hard corals, commonly referred to as "white corals" because of their lack of colour, specifically identified as Lophelia pertusa and Madrepora oculata species. The reef also contains black corals, solitary corals, sponges, and other ecologically important species, as well as fossil traces of oysters and ancient corals, the Italian Research Council said. It called them "true geological testimonies of a distant past."

Mission leader Giorgio Castellan said the finding was "exceptional for Italian seas: bioconstructions of this kind, and of such magnitude, had never been observed in the Dohrn Canyon, and are rarely seen elsewhere in our Mediterranean". The discovery will help scientists understand the ecological role of deep coral habitats and their distribution, especially in the context of conservation and restoration efforts, he added.
The undersea research was funded by the EU.

America's nonprofit College Board lets high school students take college-level classes — including a computer programming course that culminates with a 90-minute test. But students did better on questions about If-Then statements than they did on questions about arrays, according to the head of the program. Long-time Slashdot reader theodp explains: Students exhibited "strong performance on primitive types, Boolean expressions, and If statements; 44% of students earned 7-8 of these 8 points," says program head Trevor Packard. But students were challenged by "questions on Arrays, ArrayLists, and 2D Arrays; 17% of students earned 11-12 of these 12 points."

"The most challenging AP Computer Science A free-response question was #4, the 2D array number puzzle; 19% of students earned 8-9 of the 9 points possible."
You can see that question here. ("You will write the constructor and one method of the SumOrSameGame class... Array elements are initialized with random integers between 1 and 9, inclusive, each with an equal chance of being assigned to each element of puzzle...") Although to be fair, it was the last question on the test — appearing on page 16 — so maybe some students just didn't get to it.

theodp shares a sample Java solution and one in Excel VBA solution (which includes a visual presentation).

There's tests in 38 subjects — but CS and Statistics are the subjects where the highest number of students earned the test's lowest-possible score (1 out of 5). That end of the graph also includes notoriously difficult subjects like Latin, Japanese Language, and Physics.

There's also a table showing scores for the last 23 years, with fewer than 67% of students achieving a passing grade (3+) for the first 11 years. But in 2013 and 2017, more than 67% of students achieved that passsing grade, and the percentage has stayed above that line ever since (except for 2021), vascillating between 67% and 70.4%.

2018: 67.8%
2019: 69.6%
2020: 70.4%
2021: 65.1%
2022: 67.6%
2023: 68.0%
2024: 67.2%
2025: 67.0%

"A federal class action lawsuit filed this week in Texas accused Toyota and an affiliated telematics aggregator of unlawfully collecting drivers' information and then selling that data to Progressive," reports Insurance Journal: The lawsuit alleges that Toyota and Connected Analytic Services (CAS) collected vast amounts of vehicle data, including location, speed, direction, braking and swerving/cornering events, and then shared that information with Progressive's Snapshot data sharing program. The class action seeks an award of damages, including actual, nominal, consequential damages, and punitive, and an order prohibiting further collection of drivers' location and vehicle data.
Florida man Philip Siefke had bought a new Toyota RAV4 XLE in 2021 "equipped with a telematics device that can track and collect driving data," according to the article. But when he tried to sign up for insurance from Progressive, "a background pop-up window appeared, notifying Siefke that Progressive was already in possession of his driving data, the lawsuit says. A Progressive customer service representative explained to Siefke over the phone that the carrier had obtained his driving data from tracking technology installed in his RAV4." (Toyota told him later he'd unknowingly signed up for a "trial" of the data sharing, and had failed to opt out.) The lawsuit alleges Toyota never provided Siefke with any sort of notice that the car manufacture would share his driving data with third parties... The lawsuit says class members suffered actual injury from having their driving data collected and sold to third parties including, but not limited to, damage to and diminution in the value of their driving data, violation of their privacy rights, [and] the likelihood of future theft of their driving data.
The telemetry device "can reportedly gather information about location, fuel levels, the odometer, speed, tire pressure, window status, and seatbelt status," notes CarScoop.com. "In January, Texas Attorney General Ken Paxton started an investigation into Toyota, Ford, Hyundai, and FCA..." According to plaintiff Philip Siefke from Eagle Lake, Florida, Toyota, Progressive, and Connected Analytic Services collect data that can contribute to a "potential discount" on the auto insurance of owners. However, it can also cause insurance premiums to be jacked up.
The plaintiff's lawyer issued a press release: Despite Toyota claiming it does not share data without the express consent of customers, Toyota may have unknowingly signed up customers for "trials" of sharing customer driving data without providing any sort of notice to them. Moreover, according to the lawsuit, Toyota represented through its app that it was not collecting customer data even though it was, in fact, gathering and selling customer information. We are actively investigating whether Toyota, CAS, or related entities may have violated state and federal laws by selling this highly sensitive data without adequate disclosure or consent...

On his YouTube channel, consumer protection attorney Steve Lehto shared a related experience he had — before realizing he wasn't alone. "I've heard that story from so many people who said 'Yeah, I I bought a brand new car and the salesman was showing me how to set everything up, and during the setup process he clicked Yes on something.' Who knows what you just clicked on?!"
