Biomachining: Using Bacteria to Machine Metal

2025-01-28

Biomachining is a novel machining process employing lithotrophic bacteria, such as Thiobacillus ferrooxidans and Thiobacillus thiooxidans, to remove material from metal parts. These bacteria utilize the chemical energy from iron or copper oxidation to remove material from a metal surface when immersed in a culture fluid. Unlike traditional chemical or physical machining, biomachining offers a low material removal rate and a superior surface finish, making it ideal for micromachining. This process has been successfully used on pure iron and copper, and involves masking the areas not to be machined, similar to chemical milling. The process's depth is influenced by factors like stirring rate and temperature.

Autodesk Forum Archiving Update: Community Backlash and Adjustments

2025-01-27

Autodesk's recent forum archiving policy changes sparked a significant community backlash. The initial plan to archive a large number of forum posts, including valuable code and solutions, resulted in information loss and user complaints about broken links and missing knowledge. Facing pressure, Autodesk revised its policy, stating that Idea Boards will not be archived and that forum threads with 'accepted solutions' will be preserved along with related posts. They are working to recover some archived content, but due to technical limitations, complete restoration is not guaranteed. This incident highlights the importance of communication between the company and its users and the need for more careful handling of community content to avoid unnecessary knowledge loss.

Trump 2.0 and the Ghost of McKinley: American Imperialism Revisited

This article explores the policy legacy of President William McKinley and its influence on the Trump administration. McKinley's presidency saw the rise of the US as a global superpower, and his protectionist, expansionist, and imperialist policies bear a striking resemblance to Trump's 'America First' strategy. The article analyzes the economic boom, territorial expansion, and racial ideologies of McKinley's era, comparing them to the policy goals of the Trump administration. Both prioritize American economic interests and global hegemony while downplaying international cooperation and human rights. While acknowledging differences, the article concludes that the Trump administration's policy direction echoes McKinley's 'America First' ideology, with profound implications for the future global landscape.

Utah Bill Demands Transparency for AI-Generated Police Reports

Utah Bill Demands Transparency for AI-Generated Police Reports

A Utah Senate bill (S.B. 180) would mandate disclosure when police reports are generated by AI. The bill requires police departments to establish AI usage policies, including disclaimers on AI-generated content and officer certification of accuracy. This follows the rapid spread of Axon's Draft One, which uses bodycam audio to create reports. Critics warn of AI's potential to misinterpret language, provide plausible deniability for officers, and compromise justice. King County, Washington prosecutors have already instructed officers to avoid using the technology. While a step towards regulation, stronger oversight is needed to address the concerns surrounding AI in law enforcement.

CES 2025 TVs: More AI Gimmicks Than Real Improvements

At CES 2025, TV manufacturers showcased AI-powered smart TVs, but Ars Technica's author expresses disappointment. Many touted AI features, such as LG's AI remote lacking a direct input switching button and Samsung's AI food recognition, prioritize corporate interests over user needs. Google TV's Gemini-enhanced Assistant also raises questions about practicality and potential subscription fees. The author argues that the industry's focus on software and data collection overshadows hardware improvements and user experience, forcing consumers to pay for largely useless features. Ultimately, many consumers simply desire TVs with superior picture and sound quality, a goal increasingly difficult to achieve without navigating through excessive gimmicks.

US and Canada Video Game Workers Form Industry-Wide Union

US and Canada Video Game Workers Form Industry-Wide Union

A landmark industry-wide union for video game workers in the US and Canada, the United Videogame Workers-CWA (UVW-CWA), has officially launched. Aiming to unite artists, writers, designers, QA testers, programmers, freelancers, and more, the union seeks to empower workers regardless of studio or employment status. Debuting at GDC's "Video Game Labor at a Crossroads" panel, the UVW-CWA will circulate a petition to garner support and highlight the recent wave of industry layoffs—a significant issue, given that 10% of developers lost their jobs in 2024. The union operates on a direct-join model, allowing workers to bypass traditional unionization processes. While its industry-wide adoption and recognition by major publishers remain uncertain, it represents a significant step in the ongoing struggle between game industry workers and corporate entities.

AI Inference Costs: Not as Expensive as You Think

AI Inference Costs: Not as Expensive as You Think

This article challenges the narrative that AI inference is prohibitively expensive and unsustainable. By calculating the costs of running AI inference on H100 GPUs, the author demonstrates that input processing is incredibly cheap (fractions of a cent per million tokens), while output generation is significantly more expensive (dollars per million tokens). This cost asymmetry explains the profitability of some applications (like coding assistants) and the high cost of others (like video generation). The author argues that this cost disparity is often overlooked, leading to an overestimation of AI inference costs, which may benefit incumbents and stifle competition and innovation.

A 50-Year-Old Bug in C's File I/O: Unraveling a Legacy Mystery

2024-12-26

While improving a DOS emulator, a developer stumbled upon a seemingly trivial bug in file I/O: appending text to a file using the `echo` command produced unexpected results. Debugging revealed a flaw in how C runtime libraries handle switching between reading and writing, a flaw tracing back to the 1970s and even earlier UNIX systems. The article delves into the historical context, from early K&R C to modern C standards, exploring implementation differences across various UNIX versions and C compilers. The root cause is identified as limitations in early C libraries' handling of update mode, with variations in how different operating systems and compilers addressed these limitations. The author concludes that even today, for portable C code, an explicit `fseek` call is necessary when switching between reading and writing a file.
