No app, no entry: How the digital world is failing the non tech-savvy

Source: Hacker News

Article note: The accessibility issue for elderly/illiterate/unbanked/disabled folks is totally a problem. The fragility is also as least as big a problem, both in the "mobile devices and their connectivity aren't all that trustworthy" and "a small technical glitch can wipe out your only available workflow" sense. And the Intrusiveness issue is a problem for everyone. I'm not going to install your fucking app and let it try to suck every bit of personal information out of my phone to buy a sandwich.

Rocky Linux backer CIQ rejects lawsuit’s claims it was founded on stolen IP

Article note: It sure looks like a situation where Greg (&co.) were doing open-source work to benefit the community and making "enough" off of support and contract dev and such, some folks at Sylabs got greedy, and everyone who was there to do engineering not rentseeking mosied on out. It seems to happen pretty regularly with open source stuff used by enterprise customers, and it's not even the first time it's happened to him.

Brands allegations as 'meritless' after being sued by HPC software provider Sylabs

A recently unsealed lawsuit filed in the US by HPC software provider Sylabs accuses rival outfit Ctrl IQ (CIQ) and its founder Greg Kurtzer of violating Sylab's trade secrets in order to start its business, and of filing its own patents based on that technology.…

Political polarization toned down through anonymous online chats

Source: Ars Technica

Article note: Man, I feel grimly validated this stuff. Back when it was "We're going to _civilize_ the Internet with real name policies" I had a real strong "This will backfire, encouraging people to get their whole identity tied up in their bad behavior will only make it worse" expectation, and boy was I right (..and it was always really about selling personal information to third parties anyway). The descent into algorithmically curated filter bubbles, and communities not typically built around a demographic cross-cutting shared interest has not been good for society.

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.

Judge rules that AI-generated art isn’t copyrightable, since it lacks human authorship

Source: Engadget

Article note: Hey, this is a partial answer to one of my old thought experiments about "it'd be pretty easy to write a program (and/or physical art piece with one of those RGB LED grids) that generates all valid favicons, discuss the copyright implications."

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.

Only 8 Chips Make A CPU

Source: Hack a Day

Article note: Ooh, that's a clever use of the ol' EPROM-as-lookup-table trick, to construct a bit-serial processor more or less by bolting bit-serial RAMs and ROMs onto said lookup table.

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.

Thanks to [Ken Boak] for the tip.

3D printer nightmare fuel: Bambu X1C and P1P started printing while owners were asleep

Source: The Verge - All Posts

Article note: Yeah, that's a big fuckup about something the community is skeptical of them about. I've played with an X1Cs, they're _superb_ printers with well-thought-out kinematics, the most reliable filament changer on the market by a considerable margin, some amazing feedback-driven harmonic management, are super fast ... and contain an unfortunate amount of proprietary parts/software and unwanted connectivity. I think I'd do a Voron Trident (kit) if I decided I needed a higher performance printer right now, it has similar kinematics (I'm weakly convinced CoreXY over Z bed is better than CoreXY on flying gantry) but is open source all the way down.

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.

Ok so this is a bit concerning, I have zero clue how their system is setup (yay proprietary closed source) but it looks like a disruption in Bambulab`s cloud service cause a whole bunch of peoples printers to just.....start printing last night. pic.twitter.com/Sqbk9zmc60
