Keystroke timing obfuscation added to ssh(1)
Summary: OpenBSD has added keystroke timing obfuscation to its ssh(1) client, aiming to hide inter-keystroke timings by sending interactive traffic at fixed intervals and fake "chaff" keystrokes. This feature is controlled by the new ssh_config ObscureKeystrokeTiming keyword and uses a pair of new SSH protocol extensions. The update is expected to appear in other systems via openssh-portable soon.

Accessible Palette: stop using HSL for color systems
Summary: Wildbit's Accessible Palette app helps designers create color systems with consistent lightness and predictable contrast ratios. The tool addresses issues with the HSL color model and allows users to customize lightness levels, contrast ratios, and hue shifts. Accessible Palette also calculates contrast ratios using both WCAG 2.1 Recommendations and the upcoming WCAG 3.0 Working Draft's Advanced Perceptual Contrast Algorithm (APCA).
