  • Iran-linked Cyberattackers Shut Down a UK Power Plant for Four Days
    by EditorDavid on 23/08/2026 at 6:53 pm

    "Iran shut down a British power plant for four days in an unprecedented cyber attack," reports the Telegraph. More details from the BBC: The government said that at no point was there a risk to the UK's energy system, but the Department for Energy Security and Net Zero (DESNZ) has contacted power companies to advise them about the risk of cyber attacks... DESNZ said the incident had affected a small-scale generator and at no point had there been a risk to the wider energy system. The UK's power network has a number of smaller gas generators which provide short-term power when needed. Thanks to Alain Williams (Slashdot reader #2,972) for sharing the news.

  • Slovakia Finds Russian Backdoor In Traffic Speed Cameras
    by EditorDavid on 23/08/2026 at 5:38 pm

    Slovakia acquired speed cameras to modernize its traffic control-- but there was a surprise. Tom's Hardware cites this story from the Risky Bulletin Newsletter: Unfortunately, the country's national security service, the NBU, has discovered that the cameras have multiple security issues. Firstly, they have SMS-activated Russian backdoors. Secondly, live camera feeds can be accessed by anyone with the device IP, no password necessary... [The cameras] are thought to be rebranded Russian CORDON PRO.M traffic cameras, produced by a St. Petersburg-based firm called Semicon... reportedly bought via a Cyprus-based shell company with fake certifications. Reports also suggest that pressure from the opposition political party in Slovakia led to the NBU investigations... Probably most seriously, in terms of national security, these cameras contain a hardcoded list of Russian phone numbers, which can be used to open a backdoor. An SMS from one of these numbers can open shell and network access... [T]he SecureBoot feature is ineffective, and the web management portal can be accessed, exposing live streams, by anyone with the camera IP. Cameras that have been installed and set up have since been deactivated by the Slovak Ministry of the Interior. Meanwhile, for due diligence, an independent auditor will be called in to confirm the NBU's findings. It is thought that Croatia, and some other countries in Eastern Europe, may have undiscovered issues with traffic control cameras of similar origin. Read more of this story at Slashdot.

  • Stanford Economist Now Believes an AI Job Apocalypse Is Unlikely
    by EditorDavid on 23/08/2026 at 4:34 pm

    "There is still no sign of economy-wide job destruction," says economist Erik Brynjolfsson. Working with researchers at the Stanford Digital Economy Lab, Brynjolfsson has determined an AI "job apocalypse" is unlikely, reports the Washington Post, "even though it will likely impact entry-level jobs." And Brynjolfsson "predicts that demand for experienced workers such as senior coders will still be high even if AI takes on more routine knowledge and coding work in the future." Earlier this month, Brynjolfsson and his colleagues at the Stanford Digital Economy Lab updated their widely publicized report, "Canaries in the Coal Mine? Six Facts about the Recent Employment Effects of Artificial Intelligence," to reflect that they do not see widespread, economy-wide job displacement associated with AI... Brynjolfsson: What has moved on the upside is productivity. Nonfarm business productivity growth is running over 2 percent, the best sustained stretch since the late-1990s boom... The gains show up years after the investment, and they're starting to show up... By 2030, we will have enormously more capable AI, meaningfully faster productivity growth and an unemployment rate that looks unremarkable — somewhere in its historical range. That surprises people, but it's what the mechanism implies... [T]he technology is becoming much more powerful, and it's going to be even more powerful. Secondly, there are huge implications for business and the economy, including some increases in living standards, but also, potentially, job disruption. And then, thirdly, we must act now to address this gap. We can't just sit back and wait for the tsunami to hit us. And one of the things we can do is put in place institutions, policies and research to make the technology more complementary — using AI to complement people so it creates more jobs. A common misconception among business managers is AI, in order to be effective, has to reduce jobs. That's just not true. You can use AI to increase employment and productivity at the same time. It's kind of a win-win... Right now, tax policy is very skewed toward favoring capital versus labor — and, as a consequence, a lot of entrepreneurs and managers, they're basically being guided by the federal government to replace workers with machines. And I don't think that's necessarily what we'd like to have happen. From an economist's perspective, what you want to be doing is not mimicking and replacing things. You want to be extending and complementing — have humans do new things they never could have done before. He acknowledges "real, persistent and widening" effects on entry-level jobs, with a labor market "closing the on-ramp for people starting their careers... If companies don't hire people at the base of the pyramid, then they're not going to have those people later when they need them." One he points out that one company is instead using AI to speed up its training of young employees. Read more of this story at Slashdot.

  • 23 Years After SimCity 4's Release, 'Eternal Commuter' Bug Finally Fixed
    by EditorDavid on 23/08/2026 at 3:34 pm

    "It began life just a year after SimCity 4's 2003 launch," writes the blog PCGamesN. "Now, over 20 years later, it's still going strong with the arrival of Network Addon Mod update 50." The SimCity 4 Network Addon Mod, or simply 'NAM' among the community, has long been a de facto recommendation to anyone looking to pick up the classic city builder. It's a comprehensive overhaul to the game's transportation and infrastructure networks that combines key fixes with a vast set of additional build pieces such as overpasses, intersections, on-ramps, roundabouts, and so on.... [Y]ou'll be able to place down elements adjacent to one another that might previously have needed a one-tile gap between them. Streets can be dragged diagonally, slope tolerances have been improved, and you can build tunnels with the street network. The new version also includes a fix for the 'Eternal Commuter Loop' bug, which might sound fairly innocuous if you're not deep in the weeds. In actuality, it's a 23-year-long frustration that has plagued modders ever since launch. Essentially, it's a problem with the regional pathfinding across city boundaries in certain layouts, causing your Sims to bounce from location to location in search of work without actually taking up a job in any of them. Your zone demand is ruined, traffic builds to unsustainable levels, and the economy falls to pieces before your very eyes. Until now, the only real solution was to simply avoid building layouts that gave your commuters the chance to loop between locations. Now, by blocking specific neighbor-to-neighbor routes while allowing the rest to run as normal, the problem has been resolved... Equally impressively, the mandatory implementation of the DLL has reduced the size of the NAM codebase "by almost 90% and by more than ten million lines, making it easier to maintain and reducing the chance of bugs."

  • Canonical is Funding a PhD to Automate C to Rust Translation
    by EditorDavid on 23/08/2026 at 2:34 pm

    An anonymous reader shared this report from the blog It's FOSS: Canonical has committed funding to a three-year PhD project focused on building a system that can automatically translate large C codebases into Rust. And they are not alone; UK Research and Innovation is matching their funding for the project, which is set to run through the University of Bristol's Programming Languages Research Group. The PhD is aiming to build an all-encompassing platform that can take a C repository running into hundreds of thousands of lines and translate it into Rust that's "safe, behaviourally correct and maintainable Rust." The work will be carried out by a student, Alex Wood, who will be supported by Professor Meng Wang leading the work, with Dr. Cristina David and Canonical's Jon Seager serving as co-supervisors.

  • Supply Chain Issues Delaying US Grid Batteries' Installation
    by EditorDavid on 23/08/2026 at 11:34 am

    Falling prices have made grid-scale storage batteries more attractive, reports Bloomberg. But after decades of stagnant investment, America's grids "are racing to make the upgrades needed to plug them in," with supplies straining for the necessary equipment. Demand for batteries has skyrocketed as electricity use across the U.S. swells, driven by data centers' booming energy needs and increasing electrification. It's also getting harder to get them connected to power grids... As those upgrades get delayed, storage projects are piling up in interconnection queues from coast to coast. For example, Consolidated Edison Inc., a major utility in New York state, says over the last two years the volume of battery storage projects waiting to be connected has grown by 300%... "The whole process of interconnecting these new power plants got really log-jammed and bottlenecked," said Joseph Rand, an energy policy researcher at the Lawrence Berkeley National Laboratory... Nationwide, some 750 gigawatts of energy storage projects — roughly equivalent to the generating capacity of more than 700 nuclear reactors — are in line to get grid connections, according to the lab's research. Not all of these projects will get built. Many developers already abandoned the queue because of delays. Still, the waiting time is increasing; the median was five years in 2025, up from a year and a half in 2015. The flood of battery projects is expected to continue. Wood Mackenzie, an energy consultancy, projects the U.S. energy storage market will quadruple in the next six years... [Shortages in key equipment] have driven up construction costs and time lines for grid upgrades, leaving utilities struggling to build fast enough. A drought of skilled workers is further slowing them down... In California, PG&E Corp., the state's largest utility, told regulators in January that a key driver of delays was long lead times for specialized equipment. Procuring certain breakers could take nearly four years, according to the utility, which reported a 300% increase in its interconnection workload compared to prior years. In Northern California, for example, holdups to circuit breaker upgrades to a substation in Solano County led to projected delays for two battery projects worth a combined 450 megawatts. Transmission line work in the Bay Area has put another 800 megawatts of energy storage at risk of delay, according to PG&E. Last year New York's Con Ed started requiring developers to help pay for upgrades if their projects will push power demand and strain infrastructure. But that also drew criticism: According to a survey conducted by the trade group New York Battery and Energy Storage Technology Consortium (NY-BEST), the new methodology raised costs by an average of $21 million per project, a 14-fold increase. At least 25 projects have been canceled as a result, according to the group. Battery advocates have appealed to state regulators to get Con Ed to abandon the new policy.
