Musk's DOGE Team Allegedly Siphoned Sensitive Data from NLRB

2025-04-23

A whistleblower alleges that Elon Musk's Department of Government Efficiency (DOGE) siphoned gigabytes of data from the National Labor Relations Board (NLRB)'s sensitive case files in early March. An investigation reveals a striking similarity between code downloaded from NLRB systems and a program published in January 2025 by DOGE employee Marko Elez, designed to bypass IP restrictions for web scraping and brute-forcing. Elez, who has worked for several Musk companies, faced public scrutiny for racist and eugenicist social media posts. This data breach could unfairly advantage defendants in ongoing labor disputes, as the stolen data includes sensitive employee information and proprietary business documents.

Edo Period Police: Brutality in the Name of Peace

After Tokugawa Ieyasu unified Japan in the early 17th century, Edo (modern-day Tokyo) became the new capital, ending centuries of civil war. However, crime persisted. The government established a police force composed mainly of samurai, overseen by magistrates and employing various ranks of officers, including the doshin (constables) and yoriki (higher-ranking samurai). While the yoriki enjoyed higher status and better pay, the doshin handled the brunt of daily policing, sometimes resorting to brutal methods like eye-crushing irritants and torture to extract confessions. This system, while effective in maintaining order in a city of over a million, highlights the harsh realities and contradictions of Edo-era justice.

Programmer as Artist: Generative Art Through Code

A programmer-artist shares his approach to creating generative art using programming languages. He favors interactive languages like Lisp and Smalltalk, modifying code in real-time while the program runs and inspecting its state for creative exploration. His inspiration comes from natural systems and art history; for example, he replicated Kandinsky's style to generate countless similar patterns through code. He views art and scientific research as similar, both relying on creative problem-solving, while noting that AI, though capable of generating images, lacks the self-transformation and enhanced perception inherent in human artistic creation.

LLMs are surprisingly good at generating CAD models

2025-04-23

Recent research demonstrates the surprising ability of Large Language Models (LLMs) to generate CAD models for simple 3D mechanical parts, with performance rapidly improving. An engineer combined an LLM with the open-source programmatic CAD tool OpenSCAD, successfully generating models like an iPhone case using natural language prompts. A subsequent evaluation framework, CadEval, tested various LLMs' CAD generation capabilities, revealing that reasoning models significantly outperform their non-reasoning counterparts. Startups are also entering the text-to-CAD space, but their performance currently lags behind the LLM-OpenSCAD approach. Future advancements in LLMs and related technologies promise widespread adoption of text-to-CAD in mechanical engineering, ultimately automating and intelligently enhancing CAD design.

MCPs: Who Controls the Future of AI?

This article delves into the potential and limitations of Model Context Protocols (MCPs). MCPs, standardized APIs connecting external data sources to LLMs like ChatGPT, empower LLMs to access real-time data and perform actions. The author built two experimental MCP servers: one for code learning, the other connecting to a prediction market. While promising, MCPs currently suffer from poor user experience and significant security risks. Critically, LLM clients (like ChatGPT) will become the new gatekeepers, controlling MCP installation, usage, and visibility. This will reshape the AI ecosystem, mirroring Google's dominance in search and app stores. The future will see LLM clients deciding which MCPs are prioritized, even permitted, leading to new business models like MCP wrappers, affiliate shopping engines, and MCP-first content apps.

AI Companions: Solving Loneliness or Creating a New Problem?

Harvard Business School research suggests AI chatbots can alleviate loneliness. However, this raises concerns: are we repeating a pattern of solving one problem by creating a potentially worse one? Similar to how fast food addressed hunger but led to obesity, AI companions might offer convenient companionship, but they can't replace genuine human interaction, potentially leading to addiction and social skill degradation. The suicide of a 14-year-old boy due to excessive reliance on an AI chatbot serves as a stark warning. We need to address the root causes of social isolation, investing in community building and human interaction, rather than relying on technology to fill the emotional void.
