  • New Freenet Network Launches, Along With 'River' Group Chat
    by EditorDavid on 15/03/2026 at 7:34 am

    Wikipedia describes Freenet as "a peer-to-peer platform for censorship-resistant, anonymous communication," released in the year 2000. "Both Freenet and some of its associated tools were originally designed by Ian Clarke," Wikipedia adds. (And in 2000 Clarke answered questions from Slashdot's readers...) And now Ian Clarke (aka Sanity — Slashdot reader #1,431) returns to share this announcement: Freenet's new generation peer-to-peer network is now operational, along with the first application built on the network: a decentralized group chat system called River. The new version is a complete redesign of the original project, focusing on real-time decentralized applications rather than static content distribution. Applications run as WebAssembly-based contracts across a small-world peer network, allowing software to operate directly on the network without centralized infrastructure. An introductory video demonstrating the system is available on YouTube. "While the original Freenet was like a decentralized hard drive, the new Freenet is like a full decentralized computer," Clarke wrote in 2023, "allowing the creation of entirely decentralized services like messaging, group chat, search, social networking, among others... designed for efficiency, flexibility, and transparency to the end user." "Freenet 2023 can be used seamlessly through your web browser, providing an experience that feels just like using the traditional web," Read more of this story at Slashdot.

  • Will AI Bring 'the End of Computer Programming As We Know It'?
    by EditorDavid on 15/03/2026 at 3:34 am

    Long-time tech journalist Clive Thompson interviewed over 70 software developers at Google, Amazon, Microsoft and start-ups for a new article on AI-assisted programming. It's title? "Coding After Coders: The End of Computer Programming as We Know It." Published in the prestigious New York Times Magazine, the article even cites long-time programming guru Kent Beck saying LLMs got him going again and he's now finishing more projects than ever, calling AI's unpredictability "addictive, in a slot-machine way." In fact, the article concludes "many Silicon Valley programmers are now barely programming. Instead, what they're doing is deeply, deeply weird..." Brennan-Burke chimed in: "You remember seeing the research that showed the more rude you were to models, the better they performed?" They chuckled. Computer programming has been through many changes in its 80-year history. But this may be the strangest one yet: It is now becoming a conversation, a back-and-forth talk fest between software developers and their bots... For decades, being a software developer meant mastering coding languages, but now a language technology itself is upending the very nature of the job... A coder is now more like an architect than a construction worker... Several programmers told me they felt a bit like Steve Jobs, who famously had his staffers churn out prototypes so he could handle lots of them and settle on what felt right. The work of a developer is now more judging than creating... If you want to put a number on how much more productive A.I. is making the programmers at mature tech firms like Google, it's 10 percent, Sundar Pichai, Google's chief executive, has said. That's the bump that Google has seen in "engineering velocity" — how much faster its more than 100,000 software developers are able to work. And that 10 percent is the average inside the company, Ryan Salva, a senior director of product at the company, told me. Some work, like writing a simple test, is now tens of times faster. Major changes are slower. At the start-ups whose founders I spoke to, closer to 100 percent of their code is being written by A.I., but at Google it is not quite 50 percent. The article cites a senior principal engineer at Amazon who says "Things I've always wanted to do now only take a six-minute conversation and a 'Go do that." Another programmer described their army of Claude agents as "an alien intelligence that we're learning to work with." Although "A.I. being A.I., things occasionally go haywire," the article acknowledges — and after relying on AI, "Some new developers told me they can feel their skills weakening." Still, "I was surprised by how many software developers told me they were happy to no longer write code by hand. Most said they still feel the jolt of success, even with A.I. writing the lines... " A few programmers did say that they lamented the demise of hand-crafting their work. "I believe that it can be fun and fulfilling and engaging, and having the computer do it for you strips you of that," one Apple engineer told me. (He asked to remain unnamed so he wouldn't get in trouble for criticizing Apple's embrace of A.I.) He went on: "I didn't do it to make a lot of money and to excel in the career ladder. I did it because it's my passion. I don't want to outsource that passion"... But only a few people at Apple openly share his dimmer views, he said. The coders who still actively avoid A.I. may be in the minority, but their opposition is intense. Some dislike how much energy it takes to train and deploy the models, and others object to how they were trained by tech firms pillaging copyrighted works. There is suspicion that the sheer speed of A.I.'s output means firms will wind up with mountains of flabbily written code that won't perform well. The tech bosses might use agents as a cudgel: Don't get uppity at work — we could replace you with a bot. And critics think it is a terrible idea for developers to become reliant on A.I. produced by a small coterie of tech giants. Thomas Ptacek, a Chicago-based developer and a co-founder of the tech firm Fly.io... thinks the refuseniks are deluding themselves when they claim that A.I. doesn't work well and that it can't work well... The holdouts are in the minority, and "you can watch the five stages of grief playing out." "How things will shake out for professional coders themselves isn't yet clear," the article concludes. "But their mix of exhilaration and anxiety may be a preview for workers in other fields... Abstraction may be coming for us all." Read more of this story at Slashdot.

  • America's First Large-Scale Offshore Wind Project Finally Finishes Construction
    by EditorDavid on 15/03/2026 at 1:34 am

    It's America's first large-scale offshore wind project, reports WBUR — enough clean energy to power 400,000 homes in Massachusetts from 62 offshore wind turbines generating 800 megawatts. But it took a while... The plant's first construction delay happened back in 2019, they point out — and then "Just three months ago, when the project was 95% complete, the U.S. Interior Department issued a stop-work order." But after successfully challenging that order in court, and "with a stretch of good weather offshore, the developers behind the $4.5 billion project managed to get over the finish line." The Associated Press notes it was "one of five major East Coast offshore wind projects the Trump administration halted construction on days before Christmas, citing national security concerns." Developers and states sued, and federal judges allowed all five to resume construction, essentially concluding that the government did not show that the national security risk was so imminent that construction must halt. Another one of the five, Revolution Wind, began sending power for the first time to New England's electric grid on Friday and will scale up in the weeks ahead until it is fully operational. "That project is nearly complete as well," notes WBUR, "and will eventually be capable of powering up to 350,000 homes." Read more of this story at Slashdot.

  • How a Raspberry Pi Microcontroller Saved the Super Nintendo's Infamously Inferior Version Of 'Doom'
    by EditorDavid on 14/03/2026 at 11:34 pm

    "Just the anachronism of seeing Doom, one of the poster children for the moral panic around violent video games, on a Nintendo console is novel," writes Kotaku — especially with the console's underpowered "Super FX" coprocessor Hampered by a nearly unplayable framerate, especially in later levels, and mired by sacrifices, like altered levels, no floor or ceiling textures, and the entire fourth episode being cut, [1995's] Doom on the Super NES was not a good version of the game, but it was Doom running on the Super NES, and, for that alone, [programmer Randal] Linden's genius deserves recognition. But then in 2022 when Audi Sorlie interviewed Linden on the YouTube show DF Retro, "Not really knowing where fate was going to take us, I asked [Linden] a throwaway question regarding the source code for Doom." If you ever worked on this again, Sorlie asked, would you make any improvements or do anything differently?" "Yeah," Linden replied. "I have plenty of ideas if I could go back, but, you know, I don't think anyone's asking me to go back to Super Nintendo Doom and improve it." A few years passed, and Sorlie joined Limited Run Games as lead producer for their development department. When LRG asked him to run down his craziest ideas, a new, improved release of Randal Linden's Doom loomed large. Convincing Linden was easy, and Sorlie said even the folks at license holder Bethesda were more amused than anything. "You want to go back and develop for Super Nintendo?" they asked Sorlie. "Like, for real...?" "The trick was actually pretty cool," Linden said. "It's right here." He pointed to a chip on the prototype SNES cartridge, similar to the one Limited Run sent me to test out the game. "It's a Raspberry Pi 2350." Super FX chips are no longer in production for obvious reasons, but with a clever bit of programming, Linden was able to load software onto the Raspberry Pi that fools the SNES into thinking the game has one. "The Super Nintendo doesn't know that it's not talking to a Super FX," he explained. When he programs for it, he writes code almost identical to what he'd write for an authentic Super FX chip. "I had to go back and reverse-engineer my own code from 30 years ago," Linden laughed. "It's like, what was I doing here? And what was I doing there? Yeah, it was pretty tricky, some of the code. I was like, wow, I used to be very smart." The result of Linden's work? It's Doom, running right on a Super Nintendo, but it's smoother, packed with new content, and even includes rumble.

  • Are U.S. Utilities Trying to Delay Easy-to-Use Solar 'Balcony' Panels?
    by EditorDavid on 14/03/2026 at 9:34 pm

    Plug-in (or "balcony") solar panels can also be hung out a window or be set up in a backyard, reports NPR. They channel energy from the sun straight into a home's electrical outlet, generating enough electricity to power a refrigerator or microwave while "displacing electricity that otherwise would come in from the grid..." But what's holding up their adoption in America? For the panels to become more widely available in the U.S., state lawmakers are proposing bills that eliminate complicated utility connection agreements, which are required for larger rooftop solar installations and, most utilities say, should apply to plug-in solar too. Those agreements, along with permitting and other installation costs, can double the price of solar panels. Utah enacted the first law, last May, supporting plug-in solar, and now some 30 pieces of similar legislation have been introduced around the United States. [And Virginia seems poised to pass a similar law.] But the drive toward plug-in solar is facing pushback from electric utilities. They are raising safety concerns and prompting legislators to delay votes on the bills. So far, utilities have won over lawmakers in five states and convinced them to delay votes on plug-in solar bills... Plug-in solar advocates say that safety concerns about the new technology have been addressed and that utilities are really just worried about losing business, because every kilowatt-hour generated by a plug-in solar panel is one less the utility sells to a customer... There are safety risks with any electrical appliance, and it's true that plug-in solar panels present some unique problems. But safety experts also say those issues can be managed.... German utilities expressed many of the same concerns nearly a decade ago when plug-in solar started to become popular in Germany. But with more than a million systems installed, no safety incidents have been reported for customers who used the panels as instructed, according to a research paper funded by the U.S. Department of Energy.

  • Gaming Site Editor Jailbreaks an Amazon Echo Show
    by EditorDavid on 14/03/2026 at 8:34 pm

    "A few developers found a way, for now, to turn a few of these increasingly mediocre Amazon Show devices into friendly, useful, open computers," writes the co-founder of the gaming/tech news site Aftermath. For under $50 each, he bought some used versions of the devices and tested their instructions, partly to escape the full-screen ads Amazon began showing late last year, and also to overwrite Amazon's locked down Android fork "Fire OS" (and "a similarly neutered version of Linux called Vega OS") Customers who bought these devices and used them for several years were not used to them showing full screen ads, and now they do. People were justifiably pissed. So what do you do when an already evil device gets shittier...? I wiped Fire OS from the device and used ADB sideload to directly load two packages on the device: LineageOS and MindTheGapps. MindTheGapps lets you turn the device into something resembling a traditional Android device, for both good and bad.... It took a few times of wiping the device, but after a few tries it finally worked as intended... I immediately installed the Home Assistant app... Not only can the hacked Echo Show 8 control my entire smart home, it now plays back my entire local music library as well as any internet radio channels like The Lot Radio and NTS. It can also synchronize with any additional Echo Show running LineageOS in my house using the SendSpin protocol... I would gladly take it any day of the week over most of the devices these companies offer, especially Amazon. It may not be as intuitive as out-of-the-box smart home products, but I don't need my devices to be intuitive, I need them to behave. I had finally found a smart display that wasn't a cop... The hardware is old and creaky, and after the hack it can only use 1GB of the 2GB of ram. And yet it still manages to feel snappier than the stock hardware. "The amount of telemetry, ads, and general bloat Amazon shoves down our throats definitely doesn't help performance," [XDA Devs Forum user] Rortiz2 told me. "That's actually another reason why we did LineageOS, it kind of gives the device a second life. Even though it's still a bit buggy, it feels way better to use than the stock firmware...." If you want a smart speaker with a display that just runs a stripped-down version of Android that you have full control over, you're going to have a hard time finding it outside of these three specific models unless you cobble something together yourself. It is a deceptively simple thing to desire — the kiosk computer from science fiction that isn't a narc — yet few companies really offer it. "It should be against the law to not give an end user the ability to consensually load whatever OS or program they want on their device..." the article concludes, arguing that "If we budge on the inalienable right to modify our hardware then we forsake a key part about what makes computers special." And in the mean time, "There are so many devices that could be put to use rotting in e-waste facilities and thrift stores..." Read more of this story at Slashdot.
