10 Things to Learn If You Want to Become a Linux Admin  TechRepublic

A new study reveals that about 3.8 million years after the solar system's first solids formed, Jupiter was twice its current size with a magnetic field 50 times stronger, profoundly influencing the structure of the early solar system. Phys.Org reports: [Konstantin Batygin, professor of planetary science at Caltech] and [Fred C. Adams, professor of physics and astronomy at the University of Michigan] approached this question by studying Jupiter's tiny moons Amalthea and Thebe, which orbit even closer to Jupiter than Io, the smallest and nearest of the planet's four large Galilean moons. Because Amalthea and Thebe have slightly tilted orbits, Batygin and Adams analyzed these small orbital discrepancies to calculate Jupiter's original size: approximately twice its current radius, with a predicted volume that is the equivalent of over 2,000 Earths. The researchers also determined that Jupiter's magnetic field at that time was approximately 50 times stronger than it is today. Adams highlights the remarkable imprint the past has left on today's solar system: "It's astonishing that even after 4.5 billion years, enough clues remain to let us reconstruct Jupiter's physical state at the dawn of its existence." Importantly, these insights were achieved through independent constraints that bypass traditional uncertainties in planetary formation models -- which often rely on assumptions about gas opacity, accretion rate, or the mass of the heavy element core. Instead, the team focused on the orbital dynamics of Jupiter's moons and the conservation of the planet's angular momentum -- quantities that are directly measurable. Their analysis establishes a clear snapshot of Jupiter at the moment the surrounding solar nebula evaporated, a pivotal transition point when the building materials for planet formation disappeared and the primordial architecture of the solar system was locked in. The results add crucial details to existing planet formation theories, which suggest that Jupiter and other giant planets around other stars formed via core accretion, a process by which a rocky and icy core rapidly gathers gas. The findings have been published in the journal Nature Astronomy.

Brokerage app Webull is running a “7 Years of Webull” anniversary promo (full terms) that includes some decent bonuses that are stackable. This offer is targeted at selected existing customers who have a funded account as of 5/20/25. Check your app or desktop account if you didn’t get a notification.

Offer #1: 30 Days of Webull Premium. If you deposit $100+, you get 30 days of Webull Premium, their new upgrade tier that is similar to Robinhood Gold.

Offer #2: Deposit Bonus. Pays out automatically in 12 equal monthly installments. First payment will be within 45 days of 6/30/25, so your hold time will be up to 15 months or so. The ratios are pretty good at the lower end; for example $200 for $2,000 is a 10% ratio.

Offer #3: 12-month subscription to The Wall Street Journal. Must deposit $10,000+. You need Webull Premium to keep this going, which costs $40 for a year. This is still a steep discount to the usual pricing (intro ~$100 a year for the first year, ~$500 a year ongoing).

Stacking example: If you deposit $10,001 in new funds (and invest it there for 13-15 months) and pay $40 for a year of Webull Premium, you can get both a $400 deposit bonus and 12 months of WSJ. With Webull Premium, you also make available 4.1% APY on cash sweep, 3.5% bonus on IRA contributions, and 3% bonus on IRA transfers (5-year minimum hold period for both). I’m more here for the short-term promos though, as I’m not a big fan of Webull customer service in general.

GNU C(glibc) Vulnerability Let Attackers Execute Arbitrary Code on Millions of Linux Systems  GBHackers News

Fortnite has returned to Apple's App Store in the United States after a nearly five-year absence, marking a significant victory for Epic Games in its protracted legal battle against Apple's App Store policies. The return follows an April 30 ruling where a federal judge determined Apple violated a court order requiring the company to allow greater competition for app downloads and payment methods, referring Apple to federal prosecutors for a criminal contempt investigation. Epic CEO Tim Sweeney celebrated on X with a simple "We back fam" message. The game, which had 116 million users on Apple's platform before its 2020 removal, was banned after Epic challenged Apple's practice of charging up to 30% commission on in-app payments as anticompetitive.

An anonymous reader quotes a report from Reuters: Honda said on Tuesday that it was scaling back its investment in electric vehicles given slowing demand and would be focusing on hybrids, now far more in favor, with a slew of revamped models. Japan's second-biggest automaker after Toyota also dropped a target for EV sales to account for 30% of its sales by the 2030 financial year. "It's really hard to read the market, but at the moment we see EVs accounting for about a fifth by then," CEO Toshihiro Mibe told a press conference. Honda has slashed its planned investment in electrification and software by that year by 30% to 7 trillion yen ($48.4 billion). It's one of a number of global car brands dialing back EV investment due to the shift in demand in favor of hybrids and as governments around the world ease timelines to meet emission rules and EV sales targets. Honda plans to launch 13 next-generation hybrid models globally in the four years from 2027. At the moment it sells more than a dozen hybrid models worldwide, though just three in the U.S. -- the Civic, which comes in hatchback and sedan versions, the Accord and the CR-V. It will also develop a hybrid system for large-size models that it plans to launch in the second half of the decade. The automaker is aiming to sell 2.2 million to 2.3 million hybrid vehicles by 2030, a huge jump from 868,000 sold last year. That also compares with a total of 3.8 million vehicles sold overall last year. Earlier this month, Honda announced it had put on hold for about two years a $10.7 billion plan to build an EV production base in Ontario, Canada, due to slowing demand for electric cars. Honda said, however, that it still plans to have battery-powered and fuel-cell vehicles make up all of its new car sales by 2040.

A Massachusetts man has agreed to plead guilty to hacking into one of the top education tech companies in the United States and stealing tens of millions of schoolchildren's personal information for profit. From a report: Matthew Lane, 19, of Worcester County, Massachusetts, signed a plea agreement related to charges connected to a major hack on an educational technology company last year, as well as another company, according to court documents published Tuesday. While the documents refer to the education company only as "Victim-2" and the U.S. attorney's office declined to name the victim, a person familiar with the matter told NBC News that it is PowerSchool. The hack of PowerSchool last year is believed to be the largest breach of American children's sensitive data to date. According to his plea agreement, Lane admitted obtaining information from a protected computer and aggravated identity theft and agreed not to challenge a prison sentence shorter than nine years and four months. He got access simply by trying an employee's stolen username and password combination, the complaint says, echoing a private third-party assessment of the incident previously reported by NBC News.

A new virtual machine manager called Karton is being developed specifically for the KDE Plasma desktop, aiming to offer a seamless, Qt-native alternative to GNOME-centric tools like GNOME Boxes. Spearheaded by University of Waterloo student Derek Lin as part of Google Summer of Code 2025, Karton uses libvirt and Qt Quick to build a user-friendly, fully integrated VM experience, with features like a custom SPICE viewer, snapshot support, and a mobile-friendly UI expected by September 2025. Neowin reports: To feel right at home in KDE, Karton is being built with Qt Quick and Kirigami. It uses the libvirt API to handle virtual machines and could eventually work across different platforms. Right now, development is focused on getting the core parts in place. Lin is working on a new domain installer that ditches direct virt-install calls in favor of libosinfo, which helps detect OS images and generate the right libvirt XML for setting up virtual machines more precisely. He's still refining device configuration and working on broader hypervisor support. Another key part of the work is building a custom SPICE viewer using Qt Quick from scratch: If you're curious, here's the list of specific deliverables Lin included in his GSoC proposal, though he notes the proposal itself is a bit outdated [...]. For those interested in the timeline, Lin's GSoC proposal says the official GSoC coding starts June 2, 2025. The goal is to have a working app ready by the midterm evaluation around July 14, 2025, with the final submission due September 1, 2025. You can learn more via KDE.org.
