Wealth Concentration in the US: The Top 10% Control 87% of Stocks

New data reveals a staggering concentration of wealth in the US, with the top 10% owning 87% of stocks, 84% of private businesses, 44% of real estate, and two-thirds of total wealth. This concentration has been steadily increasing since 1989. Even more alarming, the top 10% now accounts for 50% of all consumer spending, up from 36% three decades ago, with their spending increasing by 12% between September 2023 and September 2024 while working- and middle-class spending declined. This extreme wealth concentration poses significant economic risks, making traditional economic indicators less reliable and highlighting the uncertainty of the future.

Firefox and the Silent Audio Killer: How Websites Waste Your CPU and Battery

2025-02-15

The author discovered annoying white noise in Firefox, stemming from websites inefficiently using the WebAudio API's AudioContext. Many sites create and leave AudioContexts active even without playing audio, leading to excessive CPU and battery drain. While Chrome automatically suspends unused AudioContexts, Firefox doesn't, prompting the author to create a browser extension to mitigate the issue. This extension automatically suspends AudioContexts and attempts to resume them when sound is needed, saving resources.

SATA SSD's DRM Functions and Accessibility Limitations

SATA SSD's DRM Functions and Accessibility Limitations

A Linux kernel log shows warnings about an Intel SSDSCKJF360A5L SSD: "supports DRM functions and may not be fully accessible." This relates to an ATA protocol extension allowing the storage device to respond differently based on whether a request is signed by the mainboard's trusted platform module. This enables features like preventing modification of video players. Linux might have an incomplete view of the SSD, hence the warning. Additionally, the log notes the SSD's read cache is enabled but doesn't support outdated DPO or FUA techniques, which are irrelevant for SSDs.

We Misjudge What the Opposite Sex Finds Attractive, Leading to Body Image Issues

We Misjudge What the Opposite Sex Finds Attractive, Leading to Body Image Issues

A new study reveals that both men and women overestimate the opposite sex's preference for exaggerated gender characteristics. Participants created faces they believed the opposite sex would find attractive, revealing men overestimated women's preference for masculinity, and women overestimated men's preference for femininity. This misperception contributes to body dissatisfaction. The stronger the discrepancy between perceived self and ideal self, the greater the dissatisfaction. This suggests misjudging others' preferences not only skews our view of potential partners but also distorts self-image, potentially leading to negative behaviors like steroid use or eating disorders. Future research should explore these consequences.

55-Year-Old Developer Faces 10 Years for Sabotaging Former Employer's Network

A 55-year-old software developer faces up to 10 years in prison for deploying malicious code that crippled his former employer's network, resulting in hundreds of thousands of dollars in damages. Davis Lu, who worked at Eaton Corp. for 11 years, allegedly planted the code after a 2018 corporate restructuring reduced his responsibilities. The malicious code, including a self-activating 'kill switch' named 'IsDLEnabledinAD', caused system crashes, data loss, and globally impacted Eaton Corp. users upon Lu's termination in 2019.
