Comment Re:Wow. (Score 1) 116

One of my ram sticks went bad in my computer after running for 7 years. Because of the way I bought them (1 kit of 4x8MB DDR4) I had to send all four back and decided to drive to Micro Center to upgrade to 4x16 DDR4 Sticks in the interim and use the RMA'd sticks for another build.

On November 10, that cost me $299.
A year ago I could have upgraded using the same sticks for $149.

On Black Friday, I went to the same Micro Center to see what deals they had and decided to check on the RAM prices since they were inflating.

On November 26. The same exact RAM sticks were $399.

They literally went up $100 in less than 30 days.
It's even crazier since those sticks are DDR4 and have less demand since most people are upgrading to DDR5 at this point and were probably there in stock when I bought some of them on the 10th. They just marked them up since it would cost that much to replenish the stock when (most likely if at this point) they get more DDR4 RAM.

I posted this over two years ago. it's still true today: K12 Does not teach kids to think. It teaches kids to react

Basically, kids today can't do math because they were taught to react to math from a game on an iPad while using a Ti-83 calculator to pass standardized tests.

So imagine giving a 7 year old Frog Fractions on an iPad that he plays between his Screaming Minecraft vtuber and AI Chinese generated Spiderman / Super Mario Bros. YouTube watching sessions and then wondering why he can't do fractional math and sounds like someone from Idiocracy.

Manufacturer Remotely Bricks Smart Vacuum After Its Owner Blocked It From Collecting Data (tomshardware.com) 123

"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.

New Large Coral Reef Discovered Off Naples Containing Rare Ancient Corals (independent.co.uk) 13

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.

No. They probably don't want to hear the Roosters crowing in the background when employees are working from home on a Teams call and figure that since livestock isn't allowed in the office they can avoid that type of interruption.

And no. This isn't a joke. I've had at least three calls like this from Xerox Support over the past 5 years when their support site would crash and I had to call them for toner and parts support. To be fair I always got the parts and support on time so Kudos on Xerox but its definitely not something you expect to hear on a business support line.

You seem to have forgotten to delete the word "derelict" when describing the land, try not relying on AI so much.

Derelict in this use case is correct. In this case, you have landowners who don't have any interest in farming the land. Think a landowner who inherited the property from their farmer grandpa and don't have any plans to farm it but don't want to sell it for some reason. In those cases they lease the use rights yearly to farmers that do. Otherwise the farm would sit there growing grass and trees and therefore become derelict.

I'm going to need some significant proof that "farmers offered more than what the solar company did" for the land.

It shouldn't take a genius to realize that if a landowner is just profiting from land use, an energy company offering Lease + energy profit sharing looks better than just a straight land lease, even if the land lease is significantly higher up front.

Comment Re:Professor Dingleberry (Score 0) 224

First off, he's right about farmer destroying solar. There are big energy groups buying any farmland they can get cheap and putting Solar farms on them.

Locally there's a solar group that bought out leases for land that farmers were planting on that would otherwise be derelict. Even when the farmers offered to buy or lease the land at significantly higher value than what it's worth (or in one case, higher than what the solar company was leasing it for) the leasing company refused because the solar group offered stock in their company that if the solar farm is profitable would result in a solid revenue stream that would be sustainable for at least a few decades until the panels wear out.

The problem with this is that food demand is not getting smaller, and once you dedicate farmland for solar, it basically makes the land useless for anything but solar since the solar shade blocks plant growth and once the solar panels are degraded and/or the company goes under, now you have rows and rows of useless solar panels that were cemented into the ground as well as their wires and conduits (and possibly chemicals if batteries are involved) that you will absolutely have to find and remove at a significant cost in order to even attempt to return that land back into farm capable condition.

Meanwhile, Malls, Stores and Plaza's have these huge parking lots that you can easily install solar canopies in that not only shade the cars of customers and can be used to charge parked electric cars, but you immediately have an electrical customer in that Mall, Store or Plaza and the stores aren't going to care since they see it not only as a green thing, but as a customer service thing due to the shade.

Now to be fair I don't know if Trump is banning all solar or just farm solar, but it makes sense to ban farm solar to encourage more parking lot canopy solar if that is what he's planning. As for wind, I'm not sure why he's banning them other than because he doesn't like the look of them or he read that study from 50 years ago that says wind turbines kill birds (because wind turbines in the 70's moved at significantly higher RPM's than modern turbines) even though 1 solar thermal plant reportedly killed more birds and insects per year than all of the bird strikes on all modern windmills combined.

The Toughest Programming Question for High School Students on This Year's CS Exam: Arrays 65

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%

This is the American Electrola DXC-100
https://ancillary-proxy.atarimworker.io?url=https%3A%2F%2Fwww.radiomuseum.org%2Fr%2F...

This was a radio made in 1993, cost around $250-$300 in 1993 money, was made in Pittsburgh PA and qualified for the Made in USA logo at the time. 2000 (2 batches of 1000) of them were sold by a primarily shortwave Rush Limbaugh clone named Chuck Harder that was previously selling Drake branded radios made in Japan before one of his listeners challenged him to sell a "Made in USA" Radio. It's so American, when you turn it off, the Display says "USA 1" on it.

And it's made out of 80% US parts. The other 20% is made from friendly foreign components (Think Europe, because in the 90s JAPAN BAD! EVIL! TRADE WAR!!)
And it sucked. The first batch could barely pick up local AM or SW stations and the 2nd Gen while better, didn't justify the cost when a GE Superadio III or a cheap Radio Shack rebadged Sangean would smoke it for 1/3 the cost. Within a few months Chuck was selling Drake receivers again.

So Even in 1993, when we still had a semiconductor and computer industry in the US, we couldn't even build a simple radio out of 100% American made parts.
So what snowball's chance in hell do you think we have to build a PC out of 100% American parts in 2025?

Class Action Accuses Toyota of Illegally Sharing Drivers' Data (insurancejournal.com) 51

"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.'
