  • RIP: Marcia Lucas, Oscar-Winning Star Wars Editor, Dies At 80
    by EditorDavid on 30/05/2026 at 3:30 am

    ```Long-time Slashdot reader schwit1 brings word that Marcia Lucas, part of the editing team for both Star Wars and Return of the Jedi, has died at age 80 after a battle with metastatic cancer. Married to George Lucas from 1969 to 1983, Marcia is remembered by The Wrap as "a powerful asset in the early days of the Star Wars series, helping shape its voice and identity long before it became the massive global franchise..." She won an Academy Award for Best Film Editing for her work on the original "Star Wars" movie, an award that came four years after she was nominated for editing George's previous film, "American Graffiti." She additionally edited his debut feature, "THX 1138." Beyond these collaborations with her then-husband, Marcia worked as an editor with other acclaimed filmmakers like Martin Scorsese and Francis Ford Coppola. She was credited as sole editor for Scorsese's "Alice Doesn't Live Here Anymore," and served as supervising editor for "Taxi Driver" and "New York, New York." Marcia served as part of a three-person crew editing both "Star Wars" and "Return of the Jedi." On the first film, she worked alongside Paul Hirsch and Richard Chew and was personally responsible for editing the Battle of Yavin — otherwise known as the iconic "trench run" sequence near the end of the film. For "Return of the Jedi," Marcia shared credit with Sean Barton and Duwayne Dunham. "If only Lucas had people like her on the prequels instead of sycophants who worshipped him as a God..." argues this 2015 blog post noting an article calling her "the secret weapon behind Star Wars — including this anecdote from The Secret History of Star Wars : The [Star Wars] Death Star trench run was originally scripted entirely different, with Luke having two runs at the exhaust port; Marcia had re-ordered the shots almost from the ground up, trying to build tension lacking in the original scripted sequence, which was why this one was the most complicated (Deleted Magic has a faithful reproduction of the original assembly, which is surprisingly unsatisfying). She warned George, "If the audience doesn't cheer when Han Solo comes in at the last second in the Millennium Falcon to help Luke when he's being chased by Darth Vader, the picture doesn't work."

  • Dell Stock Surges 32% in One Day. Big Revenue From AI Servers Stuns Analysts
    by EditorDavid on 29/05/2026 at 11:34 pm

    Dell's stock skyrocketed 32.76% on Friday, "its best day ever," reports CNBC, after Dell "reported its fastest pace for revenue growth for any period since returning to the public market in 2018..." "Shares are now up 234% in 2026." Dell, which reported first-quarter earnings after the bell on Thursday, saw a flood of artificial intelligence-related demand for its servers, which contain graphics processing units from companies like Nvidia. Quarterly revenue soared nearly 88% year over year, with AI server revenue alone increasing 757% from a year earlier to $16.1 billion... Ben Reitzes, head of technology research at [research/investment firm] Melius, said he'd "never seen anything like" Dell's latest quarter. "They beat every line in the model, so this wasn't just AI, it was great execution," Reitzes told CNBC's "Squawk on the Street." "They beat whatever we would've thought...." Morgan Stanley wrote that while they expected a clean beat and raise this quarter, they're "eating our humble pie" off the back of Dell's results. "We got this one wrong, and our model/PT are under review," the analysts wrote. "This was — across the board — one of the most impressive quarters we've seen in our time covering Hardware, especially in the context of what is happening across the component universe."

  • Wix Is the Latest To Cut 20% of Jobs While Citing AI
    by BeauHD on 29/05/2026 at 8:00 pm

    Wix is laying off roughly 20% of its workforce, about 1,000 employees, as CEO Avishai Abrahami cites both the rapid evolution of AI and currency pressure from a stronger Israeli shekel against the dollar. The web developer joins a growing list of tech companies making similar cuts, including Amazon, Block, Cisco, Cloudflare, Meta, Microsoft, Oracle and Intuit. Fast Company reports: "We have witnessed the most significant shift in how companies are built since the invention of modern programming languages in the 1970s," [wrote Abrahami]. "This is not just about adopting new tools -- it is about rewiring how companies are built, how they think, how they manage, and how they operate. Companies that embrace this change will not only build faster; they will build things the previous generation literally could not have imagined." Abrahami also cited the poor exchange rate between the Israeli shekel and the U.S. dollar. The Israeli currency has significantly strengthened in the past few quarters against a weakening dollar, and the shekel is up nearly 30% against the greenback over the last year. "As the majority of our teams are Israel-based, a very meaningful portion of our costs are shekel-denominated, while our revenue is largely dollar-denominated," Abrahami explained on X. "This creates a structural pressure on our ability to operate at our current scale. It is a reality that directly shapes what is sustainable for our company." Read more of this story at Slashdot.

  • Blue Origin Rocket Exploded Thursday Night During Hot-Fire Test
    by EditorDavid on 29/05/2026 at 6:28 pm

    Spaceflight Now shared their video of the explosion, which the Orlando Sentinel describes as showing Blue Origin's rocket "become engulfed in flames. The fireball expands out and covers the entire launch pad as the fuselage of the rocket can be seen crumbling into the flames." Blue Origin founder Jeff Bezos said on X.com "It's too early to know the root cause but we're already working to find it. Very rough day, but we'll rebuild whatever needs rebuilding and get back to flying. It's worth it." (SpaceX founder Elon Musk posted "Sorry to see this, I hope you recover quickly.") It's unclear how this will impact future launches. "The rocket was destroyed," reports CBS News, "and as the smoke cleared, there was no sign of the erector-gantry used to move the New Glenn from its hangar to the pad and to raise it from horizontal to vertical. Likewise, one of two tall lightning towers was no longer visible." It was the first such on-pad explosion at the Cape since a SpaceX Falcon 9 rocket blew up on nearby pad 40 on Sept. 1, 2016... Blue Origin only has one New Glenn pad, the one that was damaged in the Thursday test. The New Glenn, which has launched three times, is a heavy lift rocket designed to compete head-to-head with SpaceX Falcon 9 and Falcon Heavy rockets. During New Glenn's most recent flight in April, an upper stage malfunction prevented a commercial internet satellite from reaching its planned orbit... The New Glenn destroyed Thursday was to send 48 Leo internet satellites owned by Amazon into space [which were not on board for the hot-fire test] Blue Origin posted on X.com that "Debris from our recent hotfire anomaly may wash ashore in the coming days/weeks. If you encounter any debris, do not touch or approach it for your safety." "Spaceflight is unforgiving, and developing new heavy-lift launch capability is extraordinarily difficult..." NASA Administrator Jared Isaacman posted on X.com. "âWe will provide information on any impacts to the Artemis and Moon Base programs as it becomes available."

  • Supreme Court Lets Vermont's Meta Lawsuit Proceed, Opening Door To 50-State Legal Wave
    by BeauHD on 29/05/2026 at 3:00 pm

    An anonymous reader quotes a report from Fortune: The Supreme Court on Tuesday rejected a push to avoid a lawsuit alleging that Facebook and Instagram harmed young users, a decision that comes as social media companies increasingly face legal scrutiny. Parent company Meta appealed after Vermont's highest court allowed a suit filed by its attorney general in 2023 to move forward. The company is facing similar lawsuits from states across the country, accusing it of knowingly designing addictive features. Meta had argued that it can't be sued in Vermont court because neither the company nor the app design has specific ties to the state. Vermont countered that the sites' large number of teen users gives its courts jurisdiction. The Supreme Court declined to hear the appeal in a brief, unexplained order, as is typical. The procedural decision comes after court losses for Meta and YouTube in social media addiction lawsuits in California and New Mexico. [...] Meta, for its part, has said that it has already introduced dozens of tools to support teens and their families and suggested it would have worked with the states on standards for youth social media use. Vermont Attorney General Charity Clark applauded the decision, saying it affirms "that companies that choose to do business in Vermont, like Meta, can be held accountable when they harm kids."

  • FBI Arrests CIA Official With $40 Million In Gold Bars In His Home
    by BeauHD on 29/05/2026 at 11:00 am

    A senior CIA official, David Rush, was arrested after investigators found more than $40 million in gold bars and about $2 million in cash at his Virginia home. According to the New York Times, "The only charge lodged against David Rush is that he inflated his academic credentials and obtained military leave pay worth tens of thousands of dollars." From the report: The court papers describe Mr. Rush as a "former senior executive service-level employee at a United States government agency." People familiar with the investigation say he until very recently held a senior position at the C.I.A. In a joint statement, the C.I.A. and F.B.I. said the arrest occurred on May 19, after the agency alerted the bureau. "After a C.I.A. internal investigation identified potential violations of the law, C.I.A. Director John Ratcliffe referred the information to the F.B.I. for a law enforcement investigation," the statement said. From last November to March, the court papers say, Mr. Rush asked for, and received, "a significant quantity of foreign currency and tens of millions of dollars in gold bars for work-related expenses." When the C.I.A. conducted a review of where the gold and currency were stashed, the agency was "unable to locate the gold bars or significant amounts of the foreign currency," according to court papers. On May 18, F.B.I. agents searched Mr. Rush's home and found "approximately 303 gold bars, each of which weighed approximately one kilogram," according to an affidavit. Based on the price of gold, the affidavit said, the estimated value of the gold exceeded $40 million. Investigators also seized nearly three dozen luxury watches, many of them Rolexes. The court papers do not indicate why Mr. Rush appears to have kept so much gold, and $2 million in U.S. currency, in his home, or what work project would have required him to amass such wealth.
