  • NASA Delays Artemis II To March
    by msmash on 03/02/2026 at 8:00 pm

    ClickOnThis writes: NASA has delayed the Artemis II launch to March of this year, after a wet dress-rehearsal uncovered a hydrogen leak. From the NASA article: During tanking, engineers spent several hours troubleshooting a liquid hydrogen leak in an interface used to route the cryogenic propellant into the rocket's core stage, putting them behind in the countdown. Attempts to resolve the issue involved stopping the flow of liquid hydrogen into the core stage, allowing the interface to warm up for the seals to reseat, and adjusting the flow of the propellant. Teams successfully filled all tanks in both the core stage and interim cryogenic propulsion stage before a team of five was sent to the launch pad to finish Orion closeout operations. Engineers conducted a first run at terminal countdown operations during the test, counting down to approximately 5 minutes left in the countdown, before the ground launch sequencer automatically stopped the countdown due to a spike in the liquid hydrogen leak rate.

  • Google Plots Big Expansion in India as US Restricts Visas
    by msmash on 03/02/2026 at 7:02 pm

    Alphabet is plotting to dramatically expand its presence in India [non-paywalled source], with the possibility of taking millions of square feet in new office space in Bangalore, India's tech hub. From a report: Google's parent company has leased one office tower and purchased options on two others in Alembic City, a development in the Whitefield tech corridor, totaling 2.4 million square feet, according to people familiar with the deal. The first tower is expected to open to employees in the coming months, while construction on the remaining two is set to conclude next year. Options in the real estate industry give would-be tenants the exclusive right to rent, or in some cases buy, a property at a predetermined price within a specific time frame. It's also possible Alphabet will not exercise the option to use the additional towers. If it does take all of the space, the complex could accommodate as many as 20,000 additional staff, which could more than double the company's footprint in India, said the people, asking not to be identified because the plans aren't public. Alphabet currently employs around 14,000 in the country, out of a global workforce of roughly 190,000. [...] US President Donald Trump's visa restrictions have made it harder to bring foreign talent to America, prompting some companies to recruit more staff overseas. India has become an increasingly important place for US companies to hire, particularly in the race to dominate artificial intelligence. Read more of this story at Slashdot.

  • 'Vibe Coding Kills Open Source'
    by msmash on 03/02/2026 at 6:01 pm

    Four economists across Central European University, Bielefeld University and the Kiel Institute have built a general equilibrium model of the open-source software ecosystem and concluded that vibe coding -- the increasingly common practice of letting AI agents select, assemble and modify packages on a developer's behalf -- erodes the very funding mechanism that keeps open-source projects alive. The core problem is a decoupling of usage from engagement. Tailwind CSS's npm downloads have climbed steadily, but its creator says documentation traffic is down about 40% since early 2023 and revenue has dropped close to 80%. Stack Overflow activity fell roughly 25% within six months of ChatGPT's launch. Open-source maintainers monetize through documentation visits, bug reports, and community interaction. AI agents skip all of that. The model finds that feedback loops once responsible for open source's explosive growth now run in reverse. Fewer maintainers can justify sharing code, variety shrinks, and average quality falls -- even as total usage rises. One proposed fix is a "Spotify for open source" model where AI platforms redistribute subscription revenue to maintainers based on package usage. Vibe-coded users need to contribute at least 84% of what direct users generate, or roughly 84% of all revenue must come from sources independent of how users access the software.

  • YouTube Kills Background Playback on Third-Party Mobile Browsers
    by msmash on 03/02/2026 at 5:00 pm

    YouTube has confirmed that it is blocking background playback -- the ability to keep a video's audio running after minimizing the browser or locking the screen -- for non-Premium users across third-party mobile browsers including Samsung Internet, Brave, Vivaldi and Microsoft Edge. Users began reporting the issue last week, noting that audio would cut out the moment they left the browser, sometimes after a brief "MediaOngoingActivity" notification flashed before media controls disappeared. A Google spokesperson told Android Authority that the platform "updated the experience to ensure consistency," calling background play a Premium-exclusive feature.

  • PayPal's CEO Change Blindsided HP's Board
    by msmash on 03/02/2026 at 4:00 pm

    An anonymous reader shares a report: PayPal said on Tuesday it was booting its CEO and replacing him with its board chair Enrique Lores, sparing no ambiguity as to why: "The pace of change and execution was not in line with the Board's expectations," it said in a statement. One group that was blindsided was HP, where Lores was until Tuesday serving as CEO, according to people familiar with the matter. Lores' switchup sent them rushing to launch a search process, those people said. HP's board does have internal candidates which it's considering for the top job, according to a person familiar with the board's thinking. As chair of PayPal's board, Lores played a role in a process evaluating internal and external candidates. It was unclear when or if he recused himself from the final decision to name him as CEO. But HP's board was only made aware that Lores was taking the CEO role at PayPal in recent weeks, the people said. Read more of this story at Slashdot.

  • Adobe Is Killing A Popular Animation And Game Development Program
    by msmash on 03/02/2026 at 3:00 pm

    Adobe has emailed users of Adobe Animate to let them know the popular animation and game development program will be discontinued on March 1, an abrupt decision that has angered animators and game developers who say the tool remains an industry standard in television and game production. Animate, the successor to the once-popular Flash, is widely used for graphic creation, animation and building games in HTML5. The company has not offered a reason for the shutdown. On BlueSky, artist and animator Julia Glassman wrote that many television productions, games, and animated media still rely on Animate and Flash pipelines and cannot simply pivot to entirely new software.
