  • 'Inside the Dystopian World of Germany's Free Speech Crackdown'
    by EditorDavid on 27/07/2026 at 1:34 am

    Thousands of Germans have been threatened with fines or prison sentences for social media posts, reports The Telegraph, calling the country's political speech laws "unusually stringent for an EU member state." One German had his home raided for calling a minister a "Schwachkopf [dummy]" while another was fined €2,000 (£1,700) for calling Friedrich Merz a "lying Fritz" under a law that, critics claim, makes it effectively illegal to make fun of politicians. The number of investigations under Section 86a, the Nazi symbols ban... has more than doubled over the past decade according to official police statistics. Investigations into the "political insult" law also reached record levels in 2025. The surge in cases is so vast that the UN has launched an investigation into free speech violations in Germany, a step typically reserved for dictatorships and banana republics... In one recent case, a pensioner was investigated under Section 188 for posting "Pinocchio is coming" on Facebook, after he learnt Friedrich Merz, the chancellor, was visiting his hometown... The case was dropped after the story caused an outcry in Germany, and police have since clarified that calling the chancellor Pinocchio is not a crime... In November 2024, police in Bavaria raided the home of another pensioner because he called Robert Habeck, the then vice-chancellor of Germany, a "schwachkopf", or dummy. The raid was reportedly launched after Mr Habeck personally filed a criminal complaint against the pensioner. Prosecutors eventually dropped the investigation after deciding that the insult "dummy" was not of "sufficient weight" to merit criminal charges. While such cases might seem like bizarre outliers, there are plenty of others. In 2021, police raided a man's apartment in Hamburg after he told a senator "you're such a d---," and this year a resident was fined €2,000 for calling Mr Merz a "lying Fritz". Official figures show a record 4,792 Section 188 cases were filed in Germany in 2025, with the numbers rising by nearly 85 per cent between 2023 and 2025. The article notes both left- and right-leaning free speech activists in Germany are calling for some of the stricter laws to be scrapped. And it adds that the uproar "bears some similarities to the free speech debate in Britain, where citizens have had a knock on the door from police over opinions posted online."

  • NASA Replaces ULA's Vulcan Centaur With SpaceX Falcon Heavy For Solar Storm Research
    by EditorDavid on 26/07/2026 at 9:46 pm

    There's been a change to NASA's launch of six satellites for solar storms research. Space.com reports that those satellites "were originally slated to lift off on a United Launch Alliance Vulcan Centaur rocket but have now been assigned a SpaceX Falcon Heavy, according to a NASA mission update." [NASA's Sun Radio Interferometer Space Experiment mision — or SunRISE] will fly to space as part of a rideshare mission sponsored by the U.S. Space Force's Space Systems Command. Though it's not stated specifically in the NASA release, that may be a hint as to why the mission's rocket was changed. On its most recent launch [U.S. Space Force mission USSF-87], Vulcan experienced an anomaly in one of its solid rocket boosters — the second such incident to occur during the rocket's four launches to date. Vulcan succeeded in delivering the USSF-87 payload to its designated orbit on that launch, but the recurrence of the booster issue during ascent prompted the Space Force to pause national security launches on Vulcan until it could be addressed. Which mission SunRISE will be manifested on has not yet been released, but Space Force's Space Systems Command [SSC] has already shifted other launches between Vulcan and SpaceX's Falcon 9... Falcon Heavy is SpaceX's heavy-lift launch vehicle... that consists of three modified Falcon 9 first stages, and has launched 12 times since it debuted in 2018. Four of those have delivered national security payloads to orbit, with the most recent of those, USSF-52, launching in December 2023. Falcon Heavy's most recent flight overall occurred this past April, when it sent the Viasat-3 F3 telecom satellite to orbit. Falcon Heavy's next mission will lift off with NASA's Nancy Roman Space Telescope, currently set for no earlier than Aug. 30. SunRISE is scheduled to launch later this year... Sientists will use data collected by the satellites "to improve prediction models for impending space weather, which in turn could lead to mitigation plans to better thwart the effects of such solar events on orbital infrastructure."

  • Apple's Smart Glasses Delayed, As Engineers Consider Privacy Concerns
    by EditorDavid on 26/07/2026 at 8:41 pm

    Digital Trends reports: Apple could unveil its first smart glasses at WWDC in June 2027, followed by a consumer release toward the end of the year, according to Bloomberg... Part of the delay reportedly stems from Apple's engineering and marketing teams spending more time refining the product and deciding how to address the privacy concerns... Apple has reportedly considered glasses without cameras, as well as a version where the cameras can analyse the surroundings but cannot record photos or video. Such an approach could still support object recognition, navigation, Siri, calls, and music playback. The company is also expected to favor on-device processing, avoid facial recognition, keep recordings away from AI training, and use a more visible light around the camera.

  • Google's Anti-search-scraping Lawsuit Dismissed
    by EditorDavid on 26/07/2026 at 7:41 pm

    A U.S. district court "has dismissed Google's case against SerpApi over that company's scraping of search results to train AI models," reports Computerworld. Google had claimed that it was protecting copyright holders — and that SerpApi's actions breached America's Digital Millennium Copyright Act (DMCA): [Google] made two claims: first, that no person shall circumvent a technological measure that effectively controls access to a work protected under this title, and second that no person shall manufacture, import, offer to the public, provide, or otherwise traffic in any technology, product, service, device, or component protected by the Act. SerpApi claimed that the URLs and other links that were being served by Google did not in themselves entail copyright and the judge agreed. In her judgment, she said that there was no indication that the copyright holders had authorized Google to take action against SerpApi. The case is not completely over as the judge has given Google 21 days to amend its complaint to demonstrate that it was acting on behalf of the copyright owners. SerpApi's CEO reacted to the court's ruling as "a win not just for SerpApi, but for all who depend on an open internet. We're pleased that the court rejected Google's attempts to expand the DMCA to assert control over access to public pages. The internet's founding principle — open access to usable information — is essential to driving innovation and ensuring everyone benefits from the promise of data. SerpApi will continue supporting developers, AI companies, researchers, and businesses that rely on access to public search information." Some analysis from Daring Fireball blogger John Gruber: I've come around on SerpApi in the last few months. My initial take was that it surely must be illegal for a company to scrape Google's search results and offer access to that data as an API. But I've come around to the argument that what SerpApi is doing to obtain Google search results is, well, exactly how Google scrapes the rest of the entire web to build its search index. It's all just scraping publicly accessible web pages. This December piece by Mike Masnick at Techdirt is what began to change my mind. In fact, Masnick wrote, Google "built its entire business on scraping the web without asking permission first. And now it wants to use one of the most abused provisions in copyright law to stop others from doing something functionally similar to what made Google a tech giant in the first place." Now Google is even getting heckled about the decision on social media. "If Google wants to refile the suit within the allowed 21 days, it has to admit that site owners have copyright protection of their work and THAT would open the door to them suing Google for scraping their content for AI Overviews."

  • Wildfires, Evacuations, and Smoke Hit Europe and North America
    by EditorDavid on 26/07/2026 at 6:39 pm

    270,000 people have been displaced by wildfires in France and Spain, reports the Guardian. A wildfire even forced evacuations in Scotland. And wildfires "have now scorched four million acres of land in the U.S.," reports NPR, as tens of millions of people in North America "are continuing to endure hazardous smoke from out of control wildfires burning across Canada and the Western U.S." At America's National Interagency Fire Center, NPR's wildfire correspondent says all of America's firefighting resources have now been deployed across the country. "So if we get another big fire, we're in trouble... International aid could be harder to come by if the situation in Southern Europe gets worse and firefighters are going to be needed there." Meanwhile Toronto was blanketed this week "with eye-watering, cough-inducing soot," writes a climate-change reporter for the Toronto Star newspaper, "briefly giving us the worst air quality in the world." But looking to the future after a wildfire that's 50% larger than any in Ontario's history (315,000 hectares or 778,331 acres), he had this to say about the eye-watering smoke. "It will be back." The article's headline warned of "Our smoke-filled future" and how Canada "must prepare for bigger wildfires, every summer — forever." Even if global carbon emissions were cut dramatically, so long as any greenhouse gases are being put into the atmosphere, climate scientists say the world will continue to get hotter. And as the temperature rises, the forests dry out and the wildfires will get bigger, stronger and more frequent. "It's not going to get better. It's going to get worse," said Edward Struzik, a fellow with the Institute for Energy and Environmental Policy at Queen's University and the author of Dark Days at Noon: the Future of Fire . "These fires aren't going away. Toronto is going to get smoke every summer...." The best solution would have been to dramatically cut emissions years ago. The harsh scientific reality is there's nothing we can do to stop wildfire smoke from blanketing cities for a few days every summer — and it's going to continue for decades to come. We're all going to need to buy air purifiers and masks and get used to it.... "The idea that we can thin our way through the boreal forest boggles the mind," [says Zeke Hausfather, a climate scientist at Berkeley Earth, an independent non-profit research organization]. "There aren't enough people in Canada to do that." The boreal forest in Canada is an enormous and largely roadless expanse bigger than the entire European Union. In comparison, America's much smaller forests are criss-crossed by roads, making firefighter access much quicker and easier. And the nature of the forests is fundamentally different as well, said Hausfather, who wrote an article summarizing research on the subject. "Western U.S. forests have evolved for frequent low-level fires that burn out the undergrowth — usually every five to 30 years," he said. "Historically, before fire suppression, fires would burn through, and they wouldn't actually kill the trees. They'd just kill smaller trees and clear out the brush." "The boreal forest is a fundamentally different beast," he said. "It's an ecosystem designed to burn." With smaller, more densely packed trees, the boreal is wetter and colder and doesn't burn anywhere near as often — every 100 to 200 years on average, Hausfather said. But when fire does erupt, it's often much more intense, burning up into the canopy and levelling everything in its path... Clearing out the dead wood on the ground wouldn't prevent, or even slow, the canopy fires that sweep the boreal, said Hausfather. Read more of this story at Slashdot.

  • AI-Equipped Garbage Trucks Could Soon Start Spying On People in the US
    by EditorDavid on 26/07/2026 at 5:39 pm

    America's garbage trucks can do more than just collect trash, reports Newsweek. They may also help identify code violations using AI. Officials in Cape Coral, Florida, recently considered equipping sanitation trucks with AI-powered cameras that would photograph properties as crews complete their normal collection routes. The system would have been designed to identify potential issues such as overgrown lawns, peeling paint, and illegal dumping, and to flag violations so the city staff can review them later before taking enforcement action... However, in a statement on July 13, Cape Coral officials said it would not be moving forward with the camera technology, citing cost issues and insufficient benefits. "Claims suggesting that this technology would automatically identify, cite or fine residents are inaccurate," the statement also noted... Cape Coral officials say that a camera system in the future would assist — not replace — human code enforcement officers, and employees will review any AI-generated alerts before violations are issued. "Even if such a system were to be considered in the future, any potential code violations would require review and verification by a Code Compliance Officer before any enforcement action could be taken," the organization wrote. But Cape Coral, Florida "is not the first city to explore the technology," the article notes. AI imaging systems developed by City Detect have already been deployed in several municipalities. According to the company's published case studies, Stockton, California, used the platform to analyze nearly 40,000 parcels, capturing almost 200,000 images while identifying thousands of potential code issues. Cathedral City, California, has also used the technology to assist code enforcement, while Dallas approved funding for a similar program pending final implementation.
