Oracle's Ron Pressler defends Java's memory usage as a performance strategy

In an Inside Java Podcast episode recorded at JavaOne 2026, Oracle Java Architect Ron Pressler discussed with host Nicolai Parlog why Java's often-criticized memory consumption is actually intentional. He argued that Java trades extra memory for reduced CPU cycles, a tradeoff enabled by its moving garbage collectors, which many leaner platforms cannot replicate.

XCENA and Samsung unveil MX1, a CXL memory-expansion chip with 3072 RISC-V cores

XCENA partnered with Samsung to build the MX1, a CXL 3.2 device that can expand host memory by up to 2TB of DDR5 while also connecting SSDs and performing on-board computation. The chip, made on Samsung's 4nm process, packs 3072 small RISC-V cores organized into 24 independently schedulable subsystems, alongside two Arm Cortex A53 cores for control, and draws about 40W on the chip and 90W for the full board with DIMMs.

BMW says younger drivers' phone habits drove shift away from physical buttons

BMW has attributed the reduction of physical buttons in its newer vehicles to changing driver preferences, particularly among younger customers who are more accustomed to touchscreen interfaces from smartphones. The automaker suggests this generational shift in expectations has influenced its interior design choices, moving controls into digital menus and touch panels.

GrapheneOS says Google removed MTE chip protection from Pixel 11, blocking custom ROM support

The GrapheneOS development team says it could not finish porting its security-focused Android build to Google's new Pixel 11 phones because the devices lack support for Arm's memory tagging extension (MTE), a hardware-level security feature. Developers say they built a partial port after a week of effort but had to halt the project, calling the omission an apparent cost-cutting move by Google. As a result, the team may abandon future support for Pixel devices and focus instead on Motorola hardware.

Las Vegas man Brent Kovar charged in $24 million crypto Ponzi scheme, faces 280 years

Federal prosecutors in Nevada allege Brent Kovar ran a Ponzi scheme that fraudulently raised $24 million from roughly 400 investors by claiming he used AI software on a supercomputer to mine and verify cryptocurrency. He promised annual returns of 15 to 30 percent with a full money-back guarantee, but investigators say he paid earlier investors with money from new ones and could not honor his guarantees. Kovar now faces 11 counts of wire fraud, two counts of mail fraud, and two counts of money laundering, carrying a maximum combined sentence of 280 years.

CSIRO team demonstrates working quantum battery prototype with femtosecond charging

Researchers led by CSIRO's James Quach built a quantum battery prototype that charges in femtoseconds using a phenomenon called superabsorption, where organic dye molecules packed between two mirrors respond collectively to laser light. Unlike conventional batteries, this device charges faster as more molecules are added, and the team successfully extracted a small electrical current from it, extending earlier 2022 research that only showed rapid energy absorption.

Opioid settlement funds diverted to buy Flock license-plate cameras, Mother Jones finds

A Mother Jones investigation found 19 police agencies in ten states spent nearly $1 million of opioid settlement money on automatic license plate readers from companies like Flock and Axon. The funds were originally allocated to help communities devastated by the opioid crisis, but state distribution agencies instead routed portions to police departments, which pitched surveillance tech as a crime-fighting tool.

Study finds most managers falter at employee coaching, offers four fixes

New workplace research indicates that many managers approach coaching as a rigid, scheduled event rather than an ongoing practice, often limiting it to annual reviews or occasional check-ins. This narrow view leads managers to either jump in and solve problems directly or treat coaching as an awkward, infrequent obligation. The findings point to four practical adjustments managers can make to turn coaching into a more natural, continuous part of daily work.

Google opens AI lifestyle app Dreambeans to free US accounts

Google has made Dreambeans, an AI-powered app that mines Gmail, Calendar, Photos, YouTube and search history for personalized suggestions, available to free Google Account holders in the US after previously charging for it. The app uses Google's Personal Intelligence feature to generate a limited daily set of 10 to 14 story-like recommendations, each illustrated with AI-generated artwork rather than stock photos, and includes a chat tool for follow-up questions and feedback controls to refine future suggestions.

PhD Mathematician Reflects on Leaving Academia After Arithmetic Geometry Doctorate

A newly minted PhD in Arithmetic Geometry from the University of Florida writes candidly about choosing not to pursue an academic mathematics career, describing years of quiet, unhurried study under an advisor who never pushed toward the professor track. The essay explores the gap between the intense passion typical of career mathematicians and the author's own more ambivalent relationship with the field.
