The Death of Authenticity: How 'Authenticity' Became a Commodity

2025-01-20
The Death of Authenticity: How 'Authenticity' Became a Commodity

This essay traces the evolution of 'authenticity' in contemporary culture. From the early hipster obsession with independent, non-commodified goods to the current prevalence of marketing terms like 'handmade' and 'small-batch,' authenticity has shifted from a scarce commodity to a ubiquitous one. The author argues that the rise of the internet and social media has lowered the cost of information dissemination, leading to shared value replacing scarcity and ushering in a 'post-authenticity' era. Brands are no longer simply commodities but active participants in shaping culture, demanding a more nuanced approach to critique.

One Year Debugging Sleep-Wake Hangs on Linux with AMD GPUs

2025-02-17

The author encountered a persistent issue where their Linux system, equipped with an AMD RX 570 GPU, would crash or hang after attempting to sleep, often resulting in a black screen upon waking. After over a year of intense debugging, involving journal analysis, systemd configuration tweaks, a debug shell, even Ghidra reverse engineering, the root cause was identified as an amdgpu driver bug related to VRAM backup during high memory usage. The solution, finally implemented, leverages the power management notifier API to preemptively back up VRAM before sleep, preventing memory exhaustion errors. This fix is expected in the stable Linux kernel 6.14 release.
