  • Amazon's Bahrain Data Center Targeted By Iran For US Military Support
    by BeauHD on 05/03/2026 at 4:00 pm

    Iranian state media said on Wednesday that it targeted Amazon's data center in Bahrain due to the company's support of the U.S. military. The drone strike that occurred on Sunday disrupted core cloud services and caused "prolonged" outages. Two data centers in the UAE were also damaged by drone strikes. CNBC reports: All of the facilities remain offline, according to the Amazon Web Services health dashboard. The attack in Bahrain was launched "to identify the role of these centers in supporting the enemy's military and intelligence activities," Iran's Fars News Agency said on Telegram. In addition to structural damage, the data centers also experienced power disruptions and some water damage after firefighters worked to put out sparks and fire. Some popular AWS applications experienced "elevated error rates and degraded availability" due to the incident. AWS advised cloud customers to back up their data, consider migrating their workloads to other regions and direct traffic away from Bahrain and the UAE. Read more of this story at Slashdot.

  • US Tech Firms Pledge At White House To Bear Costs of Energy For Datacenters
    by BeauHD on 05/03/2026 at 3:00 pm

    Major tech companies including Google, Microsoft, Amazon, and Meta pledged at the White House to pay for new power generation and grid upgrades needed to support their rapidly expanding datacenters. The Guardian reports: The agreement is meant to help mitigate concerns that big tech's datacenters are driving up US electricity costs for homes and small businesses at a time the administration of Donald Trump is seeking to curb inflation. "This means that the tech companies and the datacenters will be able to get the electricity they need, all without driving up electricity costs for consumers," the president said at the pledge signing event. "This is a historic win for countless American families and we'll also make our electricity grid stronger and more resilient than ever before." The so-called "Ratepayer Protection Pledge" was first announced by Trump in his State of the Union address, and comes as communities and state legislators increase scrutiny of rapidly proliferating datacenters. Datacenters consume vast amounts of electricity to run server racks and cooling systems for the development of technologies such as artificial intelligence. "Some datacenters were rejected by communities for that, and now I think it's going to be just the opposite," Trump said, referencing cancelled or postponed projects in recent months across several states after local opposition. The pledge includes a commitment by technology companies to bring or buy electricity supplies for their datacenters, either from new power plants or existing plants with expanded output capacity. It also includes commitments from big tech to pay for upgrades to power delivery systems and to enter special electricity rate agreements with utilities. The effort is aimed at drawing support from towns and cities that otherwise oppose the projects, said the Trump official, who spoke on the condition of anonymity.

  • Jensen Huang Says Nvidia Is Pulling Back From OpenAI and Anthropic
    by BeauHD on 05/03/2026 at 2:00 pm

    An anonymous reader quotes a report from TechCrunch: At the Morgan Stanley Technology, Media and Telecom conference in downtown San Francisco Wednesday, Nvidia CEO Jensen Huang said his company's recent investments in OpenAI and Anthropic are likely to be its last in both, saying that once they go public as anticipated later this year, the opportunity to invest closes. It could be that simple. While firms sometimes pile into companies until practically the eve of their public debut in search of more upside, Nvidia is minting money selling the chips that power both companies -- it's not like it needs to goose its returns by pouring even more money into either one. Nvidia, for its part, isn't offering much more on the matter. Asked for comment earlier today following Huang's remarks, a spokesman pointed TechCrunch to a transcript from the company's fourth-quarter earnings call, where Huang said all of Nvidia's investments are "focused very squarely, strategically on expanding and deepening our ecosystem reach," a goal its earlier stakes in both companies have arguably met. Still, a few other dynamics might also explain the pullback, including the circular nature of these arrangements themselves. [...] Meanwhile, Nvidia's relationship with Anthropic has looked fraught in its own right. Just two months after Nvidia announced a $10 billion investment in November, Anthropic CEO Dario Amodei took the stage at Davos and, without naming Nvidia directly, compared the act of U.S. chip companies selling high-performance AI processors to approved Chinese customers to "selling nuclear weapons to North Korea." Ouch. [...] Where that leaves Nvidia is holding stakes in two companies that, at this particular moment, are pulling in very different directions, and potentially dragging customers and partners along for the ride. Whether Huang saw any of this coming, given Nvidia's web of partnerships, is impossible to know. But his stated reason on Wednesday for likely pulling the plug on future investments -- that the IPO window closes the door on this kind of deal -- is hard to square with how late-stage private investing actually works. What's looking more probable is that this is an exit from a situation that has gotten really complicated, really fast. Read more of this story at Slashdot.

  • Solar In Poor Countries Is Creating a Huge Lead Hazard
    by BeauHD on 05/03/2026 at 1:00 pm

    schwit1 shares a report from Slow Boring: A new report (PDF) from the Center for Global Development documents that most of [the decentralized solar/battery systems used in poor countries in sub-Saharan Africa] use lead-acid batteries, like Americans use in cars. Lead-acid batteries work for a while and then need to be recycled. If they're recycled safely, that's fine. But in poor countries, most lead-acid batteries are not recycled safely and they become a huge source of toxic lead poisoning. C.G.D. believes that decentralized solar systems are currently generating somewhere between 250,000 and 1.5 million tons of unsafe lead-acid battery waste per year, a number that could grow much higher. Americans have mostly heard about lead issues in recent years due to the tragic situation in Flint, Michigan. But on the whole, lead exposure via faulty water pipes is a relatively minor issue. Across American history, the biggest culprits for lead exposure have been lead paint and leaded gasoline. Both were phased out decades ago, but old paint chips and lingering lead in soil have remained problems for years, albeit at diminishing rates. The global situation is quite different and much worse, to the point that in low- and middle-income countries, half of children have blood lead levels above the threshold that would trigger emergency action in the United States. It sounds fantastical to cite numbers this high. But there is credible (albeit somewhat uncertain) research indicating that five million people per year die as a result of lead-induced cardiovascular impairments. And roughly 20 percent of the gap in academic achievement between poor and rich countries is due to lead's impact on kids' cognitive development. The report goes on to note that lead-acid batteries dominate solar storage in poorer countries because they're far cheaper than lithium-ion alternatives. When these lead batteries reach end-of-life, they are often recycled unsafely, creating significant lead pollution. It's difficult to determine the scale of the problem due to limited data and minimal attention from policymakers, but researchers say it could become massive as solar adoption accelerates. Since safer battery technologies and proper recycling methods already exist, the issue largely stems from cost and lack of regulation. In other words, the problem is solvable if addressed early.

  • Humble Games' Former Bosses Buy the Studio's Back Catalog
    by BeauHD on 05/03/2026 at 10:00 am

    Former Humble Games executives have reacquired the publisher's catalog of more than 50 indie titles from Ziff Davis and relaunched their company as Balor Games. "For the developers we have worked with over the years, this moment is a reunion," Balor Games CEO Alan Patmore wrote in a statement. "[It has] the same leadership and the same commitment to thoughtful publishing remain in place. What changes is our scale and our focus. Balor Games is built for inventors and backed by believers. To that end, it exists to be a seal of quality for independent games." Engadget reports: The Humble Games lineup includes (among others) Slay the Spire, A Hat in Time, SIGNALIS, Forager, Coral Island, Monaco and Wizard of Legend. Separate from the Humble transaction, Balor also bought the complete catalog of Firestoke Games (which shut down last August) and publishing rights to Fights in Tight Spaces. In total, the young studio now owns the publishing rights to over 60 indie titles. Humble Games is separate from the Humble Bundle storefront. The latter is still owned by Ziff Davis. The pair view the newly anointed Balor as a developer-friendly publishing house. As for its name, Balor is a supernatural being in Irish mythology. It's sometimes depicted as having three eyes. Triple-eye, triple-I... Clever devils! The triple-I moniker is a more recent addition to the gaming lexicon. It typically means something defined by indie creativity and passion -- with a budget far less than AAA but more than a tiny two-person passion project. (Balor says it's about "high-quality, impactful games.") You wouldn't be blamed for wondering how that's different from AA. But the slant here is to define the genre less by budget and more by "indie" intangibles. You can learn more about the company's vision in an interview with GamesIndustry.biz.

  • US Cybersecurity Adds Exploited VMware Aria Operations To KEV Catalog
    by BeauHD on 05/03/2026 at 7:00 am

    joshuark writes: The U.S. Cybersecurity and Infrastructure Security Agency (CISA) has added a VMware Aria Operations vulnerability tracked as CVE-2026-22719 to its Known Exploited Vulnerabilities catalog, flagging the flaw as exploited in attacks. VMware Aria Operations is an enterprise monitoring platform that helps organizations track the performance and health of servers, networks, and cloud infrastructure. The flaw has now been added to the CISA's Known Exploited Vulnerabilities (KEV) catalog, with the U.S. cyber agency requiring federal civilian agencies to address the issue by March 24, 2026. Broadcom said it is aware of reports indicating the vulnerability is exploited in attacks but cannot confirm the claims. "A malicious unauthenticated actor may exploit this issue to execute arbitrary commands which may lead to remote code execution in VMware Aria Operations while support-assisted product migration is in progress," the advisory explains. Broadcom released security patches on February 24 and also provided a temporary workaround for organizations unable to apply the patches immediately. The mitigation is a shell script named "aria-ops-rce-workaround.sh," which must be executed as root on each Aria Operations appliance node. There are currently no details on how the vulnerability is being exploited in the wild, who is behind it, and the scale of such efforts. Read more of this story at Slashdot.
