The Curious Limitation of errno(3) in Linux

2025-07-04

The Linux errno(3) man page reveals a peculiar limitation: errno can be modified even on successful function calls, and it's never set to zero by any system call or library function. This stems from traditional Unix design where system calls typically return errno only on failure, leaving it unchanged on success. C library functions might make multiple system calls, some of which could fail without affecting the library function's overall success, leaving errno with the failure value. ANSI C and POSIX inherited this behavior, requiring errno to be meaningful only when a function fails and its documentation specifies setting errno.

Caching: Abstraction, Not Optimization

Caching: Abstraction, Not Optimization

The conventional wisdom is that caching speeds up software. The author argues this is only part of the story. After working with data movement between object storage, disk, and memory, the author posits that caching's more crucial role is simplifying software. The article explores the limitations of pre-baked caching algorithms (LRU, LFU, etc.) and suggests caching acts more as an abstraction layer, hiding the underlying storage details, freeing programmers from worrying about data tier location. Database and OS caching mechanisms exemplify this abstraction. While caching can have issues, like OS page cache and fsync misuse, this doesn't necessitate abandoning caching but rather understanding and using it better.

Context Engineering Strategies for Large Language Model Agents

2025-07-04

As large language model (LLM) agents gain traction, context engineering emerges as a crucial aspect of building efficient agents. This post summarizes four key context engineering strategies: writing (saving context outside the context window, such as using scratchpads or memories), selecting (choosing relevant context from external storage), compressing (summarizing or trimming context), and isolating (splitting context across multiple agents or environments). These strategies aim to address the limitations of LLM context windows, improve agent performance, and reduce costs. The post uses examples from companies like Anthropic and Cognition to detail the specific methods and challenges of each strategy, including memory selection, context summarization, and multi-agent coordination.

The High Cost and Complexity of Static CT Logs: A Sustainability Debate

2025-07-04

This article compares the operational costs and complexities of two CT log implementations: CompactLog and Sunlight. The author demonstrates that Sunlight's 'served directly from S3' architecture suffers from significantly higher write (22.4x) and read (500x) costs compared to CompactLog. Furthermore, Sunlight exhibits security vulnerabilities (accepting 32 spaces as a cryptographic seed), lacks caching, is complex to deploy, and has poor documentation, resulting in high operational costs and maintainability challenges. The author criticizes this design's prioritization of perceived simplicity over sustainability and security, advocating for the inclusion of smaller operators and monitors in shaping the CT ecosystem to avoid consolidation of control by large corporations or cloud providers.

How Apollo Killed the Rotating Space Station

This article explores NASA's decision in the 1960s to abandon the development of rotating space stations capable of providing artificial gravity, and the profound impact this decision had on human space exploration. While early designs were viable, the prioritization of the Apollo moon landing program led to funding cuts for artificial gravity research, resulting in humans remaining confined to zero-gravity stations for decades, leading to astronaut health problems like muscle atrophy and bone loss. Today, commercial space companies are revisiting artificial gravity stations, hoping to correct this historical detour and propel humanity towards becoming a spacefaring civilization.
