  • Instagram Discontinues End-To-End Encryption For DMs
    by BeauHD on 13/03/2026 at 11:00 pm

    Meta plans to remove end-to-end encryption (E2EE) from Instagram direct messages by May 8, 2026. "Very few people were opting in to end-to-end encrypted messaging in DMs, so we're removing this option from Instagram in the coming months," says Meta. "Anyone who wants to keep messaging with end-to-end encryption can easily do that on WhatsApp." The Hacker News reports: The American company first began testing E2EE for Instagram direct messages in 2021 as part of CEO Mark Zuckerberg's "privacy-focused vision for social networking." The feature is currently "only available in some areas" and is not enabled by default. Weeks into the Russo-Ukrainian war in February 2022, the company made encrypted direct messaging available to all adult users in both countries. Last week, TikTok said it would not introduce E2EE, arguing it makes users less safe by preventing police and safety teams from being able to read direct messages if needed.

  • Qatar Helium Shutdown Puts Chip Supply Chain On a Two-Week Clock
    by BeauHD on 13/03/2026 at 10:00 pm

    Iranian drone strikes shut down a major helium facility in Qatar, removing about 30% of global helium supply and raising concerns for the semiconductor industry, which relies on the gas for chip fabrication. "QatarEnergy declared force majeure on existing contracts on March 4, freeing it from supply obligations to customers," reports Tom's Hardware. The industry outlet Gasworld reports that no imminent restart is planned. From the report: Helium consultant Phil Kornbluth, speaking at a Gasworld webinar on March 4, said that if the outage extends beyond roughly two weeks, industrial gas distributors could be forced to relocate cryogenic equipment and revalidate supplier relationships, a process that could stretch over months regardless of when Qatari output resumes. South Korea is among the most exposed countries, which, according to the Korea International Trade Association, imported 64.7% of its helium from Qatar in 2025. The country relies heavily on helium imports to cool silicon wafers during fabrication and is understood to have no viable substitute. The country's Ministry of Trade, Industry and Resources has reportedly launched an investigation into supply and demand for 14 semiconductor materials and equipment types with high dependence on Middle Eastern sources, Nikkei reported on Wednesday. Bromine, which is used in circuit formation, is another big concern, with South Korea sourcing 90% of its imports from Israel, also party to the ongoing conflict in Iran.

  • Don't Get Used To Cheap AI
    by BeauHD on 13/03/2026 at 9:00 pm

    AI services may not stay cheap for long, as companies like OpenAI and Anthropic are currently subsidizing usage to rapidly grow market share. As these companies move toward profitability and potential IPOs, Axios reports that investors will likely push them to increase prices and improve margins. An anonymous reader shares an excerpt from the report: Flashback: Silicon Valley has seen this movie before. The so-called "millennial lifestyle subsidy" meant VC money helped underwrite cheap Uber rides and DoorDash deliveries. Before that, Amazon built its base with low prices, free shipping and, for years, no sales tax in most states. Eventually, all of these companies had to charge enough to cover costs -- and make a profit. Follow the money: The current iteration of AI subsidies won't last forever. Both OpenAI and Anthropic are widely expected to go public. Public investors will demand earnings growth and expanding margins. Even as chips get more efficient, total spending keeps rising. Labs need more capacity, more upgrades and more supply to meet demand. The bottom line: The costs of AI will keep going down. But total spend from customers will need to keep going up if AI companies are going to become profitable and investors are ever going to get returns on their massive investments.

  • Digg Relaunch Fails
    by BeauHD on 13/03/2026 at 8:00 pm

    sdinfoserv writes: After running a Reddit clone for a couple of months, the Digg beta shut down again. The website is a splash memo from CEO Justin Mezzell, blaming the latest "Hard Reset" on bots. "Building on the internet in 2026 is different," writes Mezzell. "We learned that the hard way. Today we're sharing difficult news: we've made the decision to significantly downsize the Digg team..." The decision was made after struggling to gain traction and an overwhelming influx of AI-driven bots and spam. "When the Digg beta launched, we immediately noticed posts from SEO spammers noting that Digg still carried meaningful Google link authority," says Mezzell. "Within hours, we got a taste of what we'd only heard rumors about. The internet is now populated, in meaningful part, by sophisticated AI agents and automated accounts. We knew bots were part of the landscape, but we didn't appreciate the scale, sophistication, or speed at which they'd find us." "We banned tens of thousands of accounts. We deployed internal tooling and industry-standard external vendors. None of it was enough. When you can't trust that the votes, the comments, and the engagement you're seeing are real, you've lost the foundation a community platform is built on." Despite the setback, Digg plans to rebuild with a smaller team, with founder Kevin Rose returning to work full-time on a new direction for the platform. "Starting the first week of April, Kevin will be putting his focus back on the company he built twenty+ years ago," writes Mezzell. "He'll continue as an advisor to True Ventures, but Digg will be his primary focus." Slashback: The Rise of Digg.com Read more of this story at Slashdot.

  • Backblaze Hosts 314 Trillion Digits of Pi Online
    by BeauHD on 13/03/2026 at 7:00 pm

    BrianFagioli shares a report from NERDS.xyz: Cloud storage company Backblaze has partnered with StorageReview to make a massive dataset containing 314 trillion digits of Pi publicly accessible. The digits were calculated by StorageReview in December 2025 after months of heavy computation designed to stress modern hardware. The dataset now hosted in the cloud weighs in at over 130TB, while the full working dataset used during the calculation reached about 2.1PB when intermediate checkpoints were included. The report notes that the Pi digits have been broken into roughly 200GB chunks to make it more practical for researchers or enthusiasts to download. Here's what StorageReview founder Brian Beeler said about the project: "Pushing [Pi] to 314 trillion digits was far more than a headline number. It was a sustained, months-long computational challenge that stressed every layer of modern infrastructure, from high core-count CPUs to massive high-speed storage, and it gave us valuable insight into how extreme, real-world workloads behave at scale. Making this dataset available in the Backblaze cloud takes the project a step further by opening access to one of the largest raw outputs ever generated in a single-system calculation. Hosting multi-petabyte files for the broader community is no small feat, and we appreciate Backblaze stepping up to ensure researchers, developers, and enthusiasts can explore and build on this record-setting achievement."

  • Meta Delays Rollout of New AI Model After Performance Concerns
    by BeauHD on 13/03/2026 at 6:00 pm

    Meta has delayed the release of its next major AI model after internal tests showed it lagging behind competing systems from Google, OpenAI, and Anthropic. The New York Times reports: The model, code-named Avocado, outperformed Meta's previous A.I. model and did better than Google's Gemini 2.5 model from March, two of the people said. But it has not performed as strongly as Gemini 3.0 from November, they said. As a result, Meta has delayed Avocado's release to at least May from this month, the people said. They added that the leaders of Meta's A.I. division had instead discussed temporarily licensing Gemini to power the company's A.I. products, though no decisions have been reached. [...] It takes time to improve A.I. models, and Meta can still catch up to rivals, A.I. experts said. But a longer timeline has set in at the company, with Mr. Zuckerberg tempering expectations for Avocado in the past few months. "I expect our first models will be good, but more importantly will show the rapid trajectory we're on," he said on a call with investors in January. A Meta spokesperson said in a statement: "As we've said publicly, our next model will be good but, more importantly, show the rapid trajectory we're on, and then we'll steadily push the frontier over the course of the year as we continue to release new models. We're excited for people to see what we've been cooking very soon." Read more of this story at Slashdot.
