  • Mark Zuckerberg Directed Meta To Create a Prediction Markets App
    by BeauHD on 23/06/2026 at 7:00 pm

    An anonymous reader quotes a report from the New York Times: Mr. Zuckerberg, the chief executive of Meta, recently dispatched a small team at his company to create a smartphone app similar to Polymarket and Kalshi, two employees with knowledge of the matter said. Users would not wager money, and the app would probably rely on a video game-like points system instead, one person said, though the company had not ruled out the eventual use of real money betting. The app is internally referred to as "Arena" and would function independently from Meta's social networking apps, which include Facebook, Instagram, WhatsApp and Messenger, said the employees, who spoke on the condition of anonymity to discuss confidential plans. Meta aims to grow the app by leveraging its large social networking audiences and directing them toward using it, they said. The effort, which insiders characterized as experimental but a top priority, is part of a broader push by Mr. Zuckerberg to create new types of apps based on emerging social behavior online. More than 3.56 billion people visit one or more of Meta's apps every day, an amount that has raised questions about whether those platforms have reached a saturation point. Arena is one of a handful of apps that Meta is trying out. Others include one called Meta Photos, another stand-alone app which would create new types of media using artificial intelligence, the employees said. [...] Meta insiders have cautioned that Arena remains in development and may not be released. But as executives search for ways to keep the world's largest social media sites thriving, Mr. Zuckerberg appears to be relying on his well-worn product development strategy: Follow the users.

  • Digital Euro Expected To Launch By 2029 After EU Backing
    by BeauHD on 23/06/2026 at 6:00 pm

    The European Parliament's economic committee has backed a digital euro designed to reduce Europe's dependence on US-controlled payment networks such as Visa and Mastercard. The ECB-backed currency is targeted for launch by 2029 after a full parliamentary vote and negotiations with EU member states. Euronews reports: Under the proposal, consumers would be able to hold digital euros in a dedicated wallet, subject to a holding limit that has yet to be determined. The system would support both online and offline payments and is intended to offer a high degree of privacy, with the ECB unable to directly identify users from their payment data. The ECB would provide the underlying infrastructure, while commercial banks and payment service providers would offer digital euro services to customers. Financial institutions are expected to be compensated for their participation in the scheme, while merchants will pay fees that are expected to be lower than those associated with current card transactions. How that compensation should be structured remains one of the most contentious issues ahead of negotiations with EU member states, according to three sources familiar with the discussions. [...] The European Parliament is expected to formalise the committee's position during a plenary vote in Strasbourg in early July. Negotiations with the EU's 27 member states would then begin, with lawmakers aiming to reach a final agreement before the end of the year. Read more of this story at Slashdot.

  • Meta Launches Cheaper Smart Glasses Without Ray-Ban
    by BeauHD on 23/06/2026 at 5:00 pm

    Meta has launched its first smart glasses without Ray-Ban branding. Starting at $299, they're cheaper than the Ray-Ban Meta Gen 2 while retaining EssilorLuxottica as a design and manufacturing partner. The Verge reports: As far as style and specs, the Meta Glasses aren't that different from Ray-Bans. The internal specs are the same as the recently released Ray-Ban Meta Optics Styles, with slightly longer battery life. The Adventurer models have thinner rims, while the Fury models hew a bit closer to the Meta Ray-Ban Display with a bolder, chunkier frame. You could describe the Adventurer as square, and the Fury as even more square. The Kylie glasses sport a more unique design with a distinct Y2K flavor that I'm told is meant to be worn lower on your nose. [...] While playing around with the Meta Glasses, it was hard not to notice that the camera appears smaller than in previous Ray-Ban glasses. Technically, Himel tells me, that's not new to these Meta Glasses. It was actually introduced back in March with the prescription-optimized Optics Styles. [...] Meta is quadrupling down on AI. The new Meta Glasses will all launch with Muse Spark, the first model out of Meta's Superintelligence Labs. (It'll also be arriving on older Ray-Ban and Oakley glasses in the US and Canada via a software update.) Supposedly, that means more helpful glasses. At my hands-on, I was told that Meta AI would now be less stiff. I'd be able to talk to it more naturally and get smarter responses. The AI now supports 14 more languages, including Arabic, Japanese, Mandarin, Hindi, and Korean. Pedestrian turn-by-turn navigation is also coming to Meta's displayless glasses. Later this month, there'll be a new "dynamic photo" feature that automatically takes multiple frames and then recommends the best one. Read more of this story at Slashdot.

  • Oracle Cuts 21,000 Jobs As It Embraces AI
    by BeauHD on 23/06/2026 at 4:00 pm

    Oracle cut roughly 21,000 jobs over the past year as it reorganized around AI and ramps up spending on data centers for customers such as OpenAI and Meta. The restructuring cost the company about $1.8 billion and, while Oracle says AI deployment may drive further reductions, it also warns the cuts could create skills shortages and hurt productivity. The BBC reports: The software and cloud computing firm says it had around 141,000 full-time employees as of May 31, 2026, down from about 162,000 workers at the same time last year. The "deployment of AI technologies across our operations have resulted, and may continue to result, in reductions to our workforce," the report says. The cuts, which amount to about 13% of Oracle's workforce, are part of a wider trend among tech firms as they spend hundreds of billions of dollars on building AI infrastructure like data centers.

  • UK Considers Forcing Social Media Firms To Prioritize Trusted News
    by BeauHD on 23/06/2026 at 3:00 pm

    An anonymous reader quotes a report from Reuters: Britain is considering forcing social media companies to prioritize what the government called trusted news sources as part of its broader push to tighten regulation of the sector. The culture department said on Monday it was considering requiring platforms such as Meta's Facebook, Alphabet-owned YouTube and TikTok to make content from public service media -- including the BBC, ITV and Channel 4 -- and other trusted news providers easier to find in users' feeds and searches. Boosting the visibility of regulated news providers could help tackle misinformation, particularly during crises, the government said. However, any move to influence how platforms rank content is likely to face scrutiny from the social media firms, which say such rules could override user choice and disadvantage other creators. The proposals form part of a broader overhaul of Britain's public service media system to help broadcasters compete with streaming platforms and shifting viewing habits. Ministers are also considering widening public service media status to include online-only providers, extending free-to-air protections for major sporting events to on-demand viewing, and consulting on a shift to internet-based TV from 2034 or 2044. "It is vital that we make sure that people have better access to trusted and accurate news and that our regulated public service media is seen and heard in the fierce battle against mis- and disinformation," culture minister Lisa Nandy said in a statement. The move follows the UK's recently-announced ban on social media use for those under 16. Read more of this story at Slashdot.

  • Canada Plans 'Nuclear Renaissance' With Up To 10 Reactors Built By 2040
    by BeauHD on 23/06/2026 at 11:00 am

    Canada has unveiled a national strategy to build up to 10 new nuclear reactors over the next 15 years as it seeks to double electricity-grid capacity by 2050. Energy Minister Tim Hodgson called it a plan for a "new civilian nuclear renaissance." "If our goal is to double our grid and build a low-carbon economy in less than 25 years, there is no credible plan to do that without nuclear energy and the clean, reliable baseload power it provides," Hodgson said. "There is no credible plan for Canada to become an energy superpower if we choose not to build upon one of the strongest energy advantages we have." CBC News reports: The strategy calls for construction to start on two new large-scale reactors by 2035, for five more to be planned or under development by 2040 and for at least one reactor to be under construction outside Ontario by 2035. It also calls for a Canadian-made microreactor to be finalized by 2035 and deployed to a remote community by the late 2030s. [...] Right now, Canada has four nuclear power plants -- three in Ontario and one in New Brunswick -- which generate about 15 per cent of Canada's electricity. A new proposed facility at the existing nuclear plant in Darlington, Ont., would see the first small modular reactor in the G7, capable of producing up to 300 megawatts per unit. Saskatchewan is also looking at the potential to bring small nuclear reactors online by the mid 2030s. The energy deal between Ottawa and Alberta also committed to collaborating on developing a strategy to build a nuclear power plant. Officials from Natural Resources Canada told reporters in a background briefing that construction of the reactors outlined in the new national strategy could cost more than $100 billion. The strategy does not say how Canada would pay for them, though an official pointed to the Canadian Infrastructure Bank and the Canada Growth Fund as possible funding sources. Hodgson said the strategy would double the 90,000 jobs in Canada's nuclear sector "over the coming decades." The plan also looks to expand sales of Candu reactors to new export markets. It says the government wants to break into at least four new international markets by 2040 and "engage six to 10 new nuclear entrant markets over a 15-year horizon, cementing Canada as their partner of choice." Thirty Candu reactors currently operate around the world, including in South Korea, China, India, Argentina, Pakistan and Romania, and there are plans to build two more. [...] "Reactor exports are not transactional. They establish multi-decade partnerships, creating durable geopolitical and commercial relationships that advance Canada's broader foreign policy interests," the strategy says. "As Canada works to diversify its trading relationships and strengthen ties with middle powers, Candu can be a central instrument of that strategy." Read more of this story at Slashdot.
