  • New Google Ad Imagines America's 'Declaration of Independence' Written With AI Help
    by EditorDavid on 05/07/2026 at 4:34 am

    An anonymous reader shared this report from TechCrunch: Two hundred and fifty years after the signing of the Declaration of Independence, a new commercial from Google asks: What if the Founding Fathers had access to Google Workspace? With the tagline "Group project, but make it 1776," the ad depicts a largely unseen Thomas Jefferson mid-draft when he gets a nagging text from Ben Franklin, leading to a very Google-centric collaboration process. Edits are suggested in Google Docs, a meeting gets scheduled in Google Calendar and conducted remotely via Google Meet (with every single attendee apparently turning their camera off?), then the whole thing is finalized with e-signatures; cue the fireworks. Of course, since this is an ad from a tech company in the year 2026, AI has a role to play. The fictionalized founders use Google's "help me visualize" AI tool to try out different animals on the national seal, Gemini takes notes on the meeting, and the founders also ask the chatbot for advice before declining King George III's document access request. TechCrunch call it "very tongue-in-cheek," noting that at one point Samuel Adams even asks, "Can we settle this over beers?" And they argue that "the AI evangelism is relatively discreet when compared to many other recent ads." Read more of this story at Slashdot.

  • Are Wars Blurring Lines Between Corporate and National Security?
    by EditorDavid on 05/07/2026 at 1:34 am

    Subsea cables. Ukrainian power stations. Russian oil refineries. Even airports, water-desalination plants and Amazon data centers. They've all become targets in wartime, notes the Wall Street Journal, and around the world now arguments "are already brewing between companies and governments over new regulations and potential costs." In Germany, powerful associations representing private companies and municipal utilities have pushed back against new standards for physical protection, warning they could spell financial ruin. New Zealand's government has faced resistance from industry groups over a proposal to fine critical-infrastructure companies and their directors for cybersecurity breaches... A sign of how lines are blurring: The North Atlantic Treaty Organization's 32 countries last year agreed that as part of a pact to spend 5% of economic output on defense and security, 1.5% would go to military-adjacent needs including protecting critical infrastructure and networks. Spending targets range from cybersecurity and industrial capacity to railroads, bridges and ports needed for military logistics... "We need a wide concept of defense — defense is no longer just military," said Italian Adm. Giuseppe Cavo Dragone, NATO's top military adviser. Adding to the complexity, companies now need to protect the data networks that serve as gateways to critical infrastructure. Hackers increasingly target not just computer files to steal information but also systems managing vital functions like building access and factory control, remotely causing physical damage or enabling espionage. U.S. authorities in April warned that Iranian hackers were trying to disrupt American drinking-water systems by targeting computer equipment that connects hardware with software. A year earlier, suspected Russian hackers remotely manipulated valves on a Norwegian hydroelectric dam... Another challenge will be parsing jurisdictions and liability for assets that cross international waters or are damaged in combat — such as subsea data cables or energy pipelines. Turf battles between law enforcement and militaries are already complicating efforts... "The private owner can invest in redundancy, monitoring, and repair capacity, but only governments and militaries can really deter, patrol, attribute, or respond to hostile state activity," said Marc Glasser, who worked on cybersecurity and infrastructure security for three decades at the U.S. Department of Transportation and the Department of Homeland Security.... Companies say they need greater clarity from governments on what protections they will provide and subsidies to help them defend privately owned assets that provide a public good. Most governments don't provide incentives for companies to invest more than the minimum legal resilience requirements. The article notes that in May the chief executive of California's Port of Long Beach "launched a cyber-defense operations center to thwart tens of thousands of cyberattacks daily, which jeopardize computer systems and all equipment connected to them." The article also points out that the EU adopted new regulations requiring countries to reduce vulnerabilities, and new laws proposed in the U.K. now "seek to increase penalties for subsea sabotage, updating codes that date to when telegraph cables were first laid in the 19th century."

  • New DNA Tech Identifies Soldier Killed in America's Revolution in 1780
    by EditorDavid on 04/07/2026 at 9:34 pm

    South Carolina's pine forests "have spent centuries hiding a secret as old as America itself," reports CBS News: In August 1780, British and American soldiers clashed there, leading to a terrible defeat for the Continental army [fighting for the 13 colonies rebelling against England]. Battlefield archaeologists Jim Legg and Steve Smith have been studying the site for decades, but recently, they made a shocking discovery: The sandy soil was home to several sets of remains buried in shallow graves. Metal buttons suggested the men had been Continental soldiers, but there was no other identification... About 2,000 Continental soldiers were killed, wounded or captured, and some men never returned home. Their families could only guess at their fates. But Legg and Smith's discovery, paired with an explosion in DNA technology, is changing what's possible. A set of remains, previously known only as 9B, has been identified as John Pumphrey, a young man from Maryland who enlisted in the Continental Army's 7th Maryland Regiment as young as 13... Pumphrey likely marched more than a thousand miles with the regiment. The unit fought in battles with then-Gen. George Washington in New Jersey and Pennsylvania... The Pumphrey family still exists today. The DNA that helped identify Pumphrey's remains came from three women: Pam Donahue, Karen Pumphrey Etchison, and Nancy Pumphrey White... In late June, members of the extended Pumphrey family came together to hear his story and say his name for the first time in centuries. His remains are interred in South Carolina, where he and the other soldiers were discovered, but the tombstone, once marked "Unknown," will soon have his name carved on it.

  • 842,000 American Households Lost Power Today During a Heatwave
    by EditorDavid on 04/07/2026 at 8:34 pm

    As America began celebrating its 250th birthday Saturday, 842,000 homes reported power outages, notes ABC News. Figures from tracking site PowerOutage showed states in America's Northeast and Midwest were impacted by severe weather and extreme heat. That number, which will fluctuate throughout the day as crews work to restore power, is for households, meaning that the number of people impacted by these outages is likely to be much larger... Millions of Americans, however, will be contending with a heatwave that is blanketing much of the country, including in Philadelphia where the Salute to Independence Semiquincentennial Parade that had been set for Friday was canceled due to the dangerous heat wave, according to Philadelphia ABC station WPVI. Elsewhere, America's Independence Day Parade, which was scheduled for 10:30 a.m. on July 4 in downtown Washington, D.C. was canceled by organizers late Friday evening due to the extreme heat in the District of Columbia... Amtrak announced it will be canceling a number of trains due to heat-related conditions. The outages seemed to last throughout the day, with 790,103 household outages still in effect by 4:30 p.m. EST. Ironically, the power outages hit several American states that were among the country's original 13 freedom-declaring colonies, including New Jersey (143,072 outages), Pennsylvania (40,944 outages), and Virginia (27,392 outages). CNBC adds that America's largest power grid operator said Friday "it was under a federal alert to cut electricity consumption across its territory as it battled generator outages, massive overloading on its transmission lines and a surge in air conditioning use from prolonged sweltering heat." PJM said it told utilities to reduce electricity to customers who are under contract to reduce consumption during emergencies. PJM serves 67 million people in the Mid-Atlantic, South and Washington, D.C., area. Spot wholesale electricity prices in northern Virginia, home to the largest collection of data centers in the world, have surged beyond $2,000 per megawatt hour this week. That compares to about $40 per MWh when PJM is not in distress. Read more of this story at Slashdot.

  • Did Microsoft Shift Its Profits to Low-Tax Countries?
    by EditorDavid on 04/07/2026 at 7:34 pm

    Microsoft is apparently shifting its profits to countries with low taxes — and out of countries where they have many more employees and significant sales. Back in 2005 Former Microsoft CEO Steve Ballmer even said that a low corporate tax rate "is part of the overall advantage of doing business in Ireland," remembers long-time Slashdot reader theodp. (Ballmer added "It would be disingenuous to say otherwise.") But in 2026 the EU now requires a country-by-country compliance report, and the New York Times notes that Microsoft "was most likely the first major U.S. technology company to make a so-called country by country report of its finances to comply..." Like other big companies, Microsoft uses transactions between subsidiaries to shift profits around to reduce its tax bill. The report revealed a consistent pattern: high returns in low-tax jurisdictions and slim margins in higher-tax ones. The report showed the sometimes absurd results. Microsoft said it had generated almost 40 percent of its pretax income in tax-friendly Ireland, where it employed about 3 percent of its global work force. In higher-tax Germany, the largest economy in Europe, Microsoft earned barely half of 1 percent of its global profits, it said. Excluding Ireland, the company said, it generated less than 2 percent of its worldwide pretax earnings in Europe... [In Luxembourg Microsoft said it had $283 million in pretax income with only 34 employees.] [America's] Internal Revenue Service is challenging profit-shifting transactions used by Microsoft, and is seeking back taxes of nearly $29 billion4. The company has said it disagrees with the I.R.S. and said in a securities filing that it "will vigorously contest" the proposed tax bills. This week a Microsoft blog post offered their own "context," arguing that tax is "one important measure of contribution, but it is not the only one. "Our investments, partnerships, infrastructure, and long-term presence in countries around the world also reflect a commitment to helping strengthen the economies and communities where we operate, today and for the future."

  • FSF Shares Update on 'LibrePhone' and New Automated Site Monitoring Tool
    by EditorDavid on 04/07/2026 at 6:34 pm

    At the end of 2025, the FSF launched LibrePhone project, which is working to "better understand and reverse-engineer the nonfree blobs used by a great majority of (if not all) system on a chip designs available today." The FSF's summer newsletter shares this update: We started with researching the proprietary files in Android phones supported by the Lineage project, an Android-based volunteer-led mobile phone operating system with much free software already in it. Our current, primary focus is on the radio blobs that control WiFi, Bluetooth, NFC, and cellular communications. The software freedom issues with mobile computing have been around for a long time, with the most challenging issue being the baseband/modem firmware that relies heavily on proprietary software. This creates a technical and legal maze that is nearly impossible to break free from, but that doesn't mean we should ever stop working to create free systems. It certainly doesn't mean we shouldn't liberate the software that we know can be free software. Now, half a year into this project, lead developer Rob Savoye has extracted firmware from over 200 Lineage install packages, processed 85GB of files, and imported the results of these analyses into a PostgreSQL database for cross-device comparison... [M]uch of the software and blobs we need to work through are shared across multiple devices; this means even greater strides for mobile phone freedom... As insurmountable as it may seem at times, every blob we manage to free up will be progress. The FSF has proven time and time again that it can bring the free software philosophy to life, not just by advocating for it, but by making it so. The bulletin also describes how waves of botnets from "aggressive LLM scrapers, vulnerability scanners, poorly optimized CI/CD servers" inspired the FSF to create a new free-as-in-freedom automated monitoring tool: In our efforts to combat the botnets, we optimized several detection rules to ban abusive behavior. We found the upper limit of fail2ban and replaced it with reaction, an efficient alternative with our configuration that uses ipset. We also split several monolithic machines into many separate machines so that when a web service is overwhelmed the other functions of the service do not go down with it... We found quite a few ways to respond to and prevent botnet attacks, but still faced a significant related challenge: communicating when a website or service is down... Uptime Kuma is a human-readable, automated monitoring addition to our systems... You can check out our recently-launched self-hosted Uptime Kuma instance at https://status.fsf.org/. When you see the page, you will also likely say, "Wow! The FSF and GNU sure do run a ton of services!" and you would be right... If you maintain websites and services, and are looking for a simple way to communicate publicly with your users, consider using Uptime Kuma or another free software solution instead of choosing a proprietary monitoring solution." There's also an article on the state of free-as-in-freedom videogame console emulators. Read more of this story at Slashdot.
