Political polarization in the US has become a major issue, as Republicans and Democrats increasingly inhabit separate realities on topics as diverse as election results and infectious diseases. An actual separation seems to underly some of these differences, as members of the two parties tend to live in relatively homogeneous communities, cluster together on social media, and rely on completely different news sources.

That's not a recipe for a functional society, and lots of work has gone into exploring the impact of polarization, as well as possible means of reducing it. Now, a team of researchers has tested whether social media can potentially help the situation by getting people with opposite political leanings talking to each other about controversial topics. While this significantly reduced polarization, it appeared to be more effective for Republican participants.

Anonymity is key

The researchers zeroed in on two concepts to design their approach. The first is the idea that simply getting people to communicate across the political divide might reduce the sense that at least some of their opponents aren't as extreme as they're often made out to be. The second is that anonymity would allow people to focus on the content of their discussion, rather than worrying about whether what they were saying could be traced back to them.

A federal judge has agreed with US government officials that a piece of artificial intelligence-generated art isn't eligible for copyright protection in the country since there was no human authorship involved. "Copyright has never stretched so far [...] as to protect works generated by new forms of technology operating absent any guiding human hand, as plaintiff urges here," Judge Beryl Howell of the US District Court for the District of Columbia wrote in the ruling, which The Hollywood Reporter obtained. "Human authorship is a bedrock requirement of copyright."

Dr. Stephen Thaler sued the US Copyright Office after the agency rejected his second attempt to copyright an artwork titled A Recent Entrance to Paradise (pictured above) in 2022. The USCO agreed that the work was generated by an AI model that Thaler calls the Creativity Machine. The computer scientist applied to copyright the work himself, describing the piece "as a work-for-hire to the owner of the Creativity Machine." He claimed that the USCO's "human authorship" requirement was unconstitutional.

Howell cited rulings in other cases in which copyright protection was denied to artwork that lacked human involvement, such as the famous case of a monkey that managed to capture a few selfies. "Courts have uniformly declined to recognize copyright in works created absent any human involvement," the judge wrote.

The judge noted that the growing influence of generative AI will lead to “challenging questions” about the level of human input that's required to meet the bar for copyright protection, as well as how original artwork created by systems trained on copyrighted pieces can truly be (an issue that's the subject of several other legal battles). 

However, Howell indicated that Thaler's case wasn't an especially complex one, since he admitted that he wasn't involved in the creation of A Recent Entrance to Paradise. “In the absence of any human involvement in the creation of the work, the clear and straightforward answer is the one given by the [Federal] Register: No,” Howell ruled. Thaler plans to appeal the decision.

According to Bloomberg, this is the first ruling in the US on copyright protections for AI-generated art, though it's an issue that the USCO has been contending with for some time. In March, the agency issued guidance on copyrighting AI-generated images that are based on text prompts — generally, they're not eligible for copyright protection. The agency has offered some hope to generative AI enthusiasts, though. "The answer will depend on the circumstances, particularly how the AI tool operates and how it was used to create the final work," the USCO said. "This is necessarily a case-by-case inquiry."

The agency has also granted limited copyright protection to a graphic novel with AI-generated elements. It said in February that while the Midjourney-created images in Kris Kashtanova's Zarya of the Dawn were not eligible to be copyrighted, the text and layout of the work were.

We’re no stranger to homemade CPUs on these pages, but we think that [Jiri Stepanovsky]’s 16-bit serial CPU might be a little special. Why? It has an astonishingly low chip count, with only 8 ICs in total. How on earth does he do it?

While a traditional TTL CPU has a relatively high chip count due to a parallel data bus, registers, and discrete ALU, this one takes a few shortcuts by opting for a one-bit serial bus with serial memory chips and an EPROM serving as a look-up-table ALU. Perhaps the most interesting result of this architecture is that it also allows the CPU to dispense with registers, like the Texas Instruments 16-bit chips back in the day. They all live in memory. You can see it below the break in action, streaming a video to a Nokia-style LCD.

Such a CPU would indeed have been unlikely to have been made back in the day due to the prohibitive cost of buying and programming such a large EPROM. However, old computers like the EDSAC also used a serial data path and mercury delay line memory to manage complexity. But for a solid-state CPU in 2023, we think the design is innovative. We think it would be challenging to reduce the chip count further — and no, we’re not counting designs that use a microcontroller to replicate a block of circuitry; that’s cheating — but we’re sure that somewhere there’s a designer with ideas for slimming the design further.

When owners of Bambu’s extremely well-regarded 3D printers woke up on August 15th, some found their printer had gone rogue.

Some woke up to failed prints. Some found a second copy of a previous print. And at least a few found their Bambu X1C or P1P had started smacking itself apart — damaging components — while trying to print a second copy atop the object they’d actually asked for.

These printers started printing unattended,...

The US broadband industry is united in opposition to a requirement that Internet service providers list all of their monthly fees. Five lobby groups representing cable companies, fiber and DSL providers, and mobile operators have repeatedly urged the Federal Communications Commission to eliminate the requirement before new broadband labeling rules take effect.

The trade associations petitioned the FCC in January to change the rules and renewed their call last week in a filing and in a meeting with FCC officials. The requirement that ISPs list all their monthly fees "would add unnecessary complexity and burdens to the label for consumers and providers and could result in some providers having to create many labels for any given plan," the groups said in the filing on Friday.

The trade groups said the FCC should instead "require providers to include an explanatory statement that such fees may apply and that they vary by jurisdiction, similar to the Commission's treatment of government-imposed taxes," or require "the display of the maximum level of government-imposed fees that might be passed through, so that consumers would not experience bill shock with respect to such fees."
