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.

SCCS: The Source Code Motel After 50 Years

2024-12-13

This article retrospectively examines the influence of the Source Code Control System (SCCS) over the past 50 years. Author Larry McVoy details SCCS's unique weave format, which allows for merging by reference, avoiding the inefficiencies of patch-based copying found in other systems. He explains how SCCS leverages this weave to retrieve any file version in constant time and preserves authorship across versions. While acknowledging shortcomings like long-term locks and file-orientation, McVoy highlights the efficiency of the weave format and its preservation of authorship as groundbreaking, laying the groundwork for later systems like BitKeeper.

A Decade-Old Fileserver's Second Life: Cost-Effective Storage Solution

2024-12-17

A company is still running a production machine, a fileserver over a decade old. While outdated, with a BMC requiring Java for KVM-over-IP, its 16 disk bays and 10G Ethernet ports make it ideal for repurposing. Used as a bring-your-own-disk low-cost storage server, it fulfills the need for high-capacity, low-performance storage despite its age and limited RAM. This highlights the value of reusing old hardware when requirements align.

Anthropic's Model Context Protocol (MCP) aims to connect LLMs with external tools and data, allowing apps like Claude Desktop to access databases, search engines, and more. While MCP offers exciting possibilities for expanding AI application functionality, its current implementation has shortcomings. Claude Desktop only supports local servers, lacks robust handling of complex inputs, and suffers from client-side timeouts. Furthermore, improvements are needed in documentation and configuration, such as an official registry, support for asynchronous task scheduling, and multi-client collaboration, to fully realize MCP's potential for users.
