Amazon’s Kindle devices run a custom Linux distribution that’s locked tightly to Amazon’s ecosystem. But jailbreaking a Kindle opens the door to installing third-party software that can change the behavior and add functionality. While Amazon doesn’t make it easy to do that, a new tool called WinterBreak takes advantage of a security vulnerability in Amazon’s […]

You have until the end of the day Thursday to enter and add to our charity haul.
If you've been too busy reading about giant old TVs to take part in this year's Ars Technica Charity Drive sweepstakes, don't worry. You still have a little bit of time to donate to a good cause and get a chance to win your share of over $4,000 worth of swag (no purchase necessary to win).
In the first weeks of the drive, hundreds of readers contributed tens of thousands of dollars to either the Electronic Frontier Foundation or Child's Play as part of the charity drive. But we're now in the final day of our attempt to best 2020's record haul of over $58,000.
Entries have to be received by the end of the day today (Thursday, January 2) to be considered for the sweepstakes, so if you've been putting off a donation/entry, now is the time to pull the trigger. Do yourself and the charities involved a favor and give now while you're thinking about it.
Supreme Court ruling could end Pornhub blackout across US South.
It's getting harder to access popular adult sites in the US South.
On Wednesday, Pornhub's owner, Aylo, kicked off the new year by blocking three more states that implemented age verification laws requiring ID to access porn. According to 404 Media, Florida, South Carolina, and Tennessee are now among 17 states where Aylo sites, including Pornhub, RedTube, and YouPorn, cannot be accessed.
The other blocked states are Alabama, Arkansas, Idaho, Indiana, Kansas, Kentucky, Mississippi, Montana, Nebraska, North Carolina, Oklahoma, Texas, Utah, and Virginia. Mapping it out, 404 Media noted that the Aylo blackout spans nearly the entire US South, with Georgia's age verification law set to take effect in July and likely to trigger another block that would almost complete the blackout.
2D materials are typically made at temperatures that wreck silicon chips.
Silicon chip manufacturers like Intel and TSMC are constantly outdoing themselves to make ever smaller features, but they are getting closer to the physical limits of silicon itself.
“We already have very, very high density in silicon-based architectures where silicon performance degrades sharply,” said Ki Seok Kim, a scientist working at the MIT’s Research Laboratory of Electronics.
One way around this problem is to replace silicon with graphene-like 2D materials that maintain their semiconducting properties even at a single-atom scale. Another way is building 3D chips, which squeeze more transistors into the same area without making transistors smaller. Kim’s team did both, building a 3D chip out of vertically stacked 2D semiconductors.
It sold more cars than it made in 2024 but slightly fewer than it sold in 2023.
Tesla sold almost 1.8 million cars in 2024, according to data released by the company this morning. Unfortunately for the electric automaker, it sold more than 1.8 million cars in 2023, beating this year's effort by 19,355 vehicles. But unlike last year, it managed to sell more cars than it built, with production falling by four percent in 2024.
In the final quarter of 2024, Tesla built 436,718 Models 3 and Y and delivered 471,930, clearing out a stash of inventory in the process. It built an additional 22,727 electric vehicles—the elderly Models S and X and the divisive Cybertruck—and sold 23,640 of them during the same three months. So in Q4 2024, Tesla actually achieved modest, year-over-year growth in total sales of about two percent.
But the picture of the year as a whole is less rosy. Model 3 and Y sales fell by two percent year-on-year, with production falling by slightly more. As noted, this appears to have allowed Tesla to reduce what was at one point a growing inventory of unsold vehicles.
The R-7 family of rockets originated from an ICBM developed to carry nuclear weapons.
The Russian space program reached a significant milestone over the holidays with the 2,000th launch of a rocket from the "R-7" family of boosters. The launch took place on Christmas Day when an R-7 rocket lifted off, carrying a remote-sensing satellite from the Baikonur Cosmodrome.
This family of rockets has an incredible heritage dating back nearly six decades. The first R-7 vehicle was designed by the legendary Soviet rocket scientist Sergei Korolev. It flew in 1957 and was the world's first intercontinental ballistic missile. Because the first Soviet nuclear warheads were massive, the R-7 vehicle was powerful enough to be converted into an orbital rocket.
A modified version of the R-7 rocket, therefore, launched the Sputnik satellite later in 1957. And the slightly more powerful "Vostok" version of the booster carried Yuri Gagarin into space in 1961, opening the era of human spaceflight. The first Soyuz variant, a rocket that has been upgraded multiple times but remains similar to its original form, flew in 1966. Humans still fly on the Soyuz rocket today to the International Space Station.

Hyper-personalized emails use “an immense amount” of scraped data.
Corporate executives are being hit with an influx of hyper-personalized phishing scams generated by artificial intelligence bots, as the fast-developing technology makes advanced cyber crime easier.
Leading companies such as British insurer Beazley and ecommerce group eBay have warned of the rise of fraudulent emails containing personal details probably obtained through AI analysis of online profiles.
“This is getting worse and it’s getting very personal, and this is why we suspect AI is behind a lot of it,” said Beazley’s chief information security officer Kirsty Kelly. “We’re starting to see very targeted attacks that have scraped an immense amount of information about a person.”
