The article discusses the current state of LLMs (Language Model Models) and questions their usefulness. The author wonders if they are missing out on something given that LLMs have become more muted over time and often act as simple autocomplete tools. They question the value of adding analytics to LLMs designed to mimic human behavior and why there is a need to analyze them. The author also mentions the lack of control over LLM behavior, stating that they are mostly politically correct due to oversight by big companies. The article concludes by emphasizing the limited capability of LLMs and the author’s personal experience of achieving similar results with minimal prompts.
Top 2 Comment Summary
The author expresses their interest in an affordable LLM observability platform during the early stages of development. They found a platform called DD helpful but now that they are on their own, they are more price sensitive. They believe that having a low friction way to monitor performance and check inputs/outputs would be a game changer. However, they mention a challenge they faced with a lack of support for Anthropic models and missing key information. They also state that the platforms they have come across are tightly coupled to langchain, which is not suitable for them. They plan to check out the platform mentioned in the article over the next week or two and find it very exciting.

Top 1 Comment Summary
The article discusses different codes and plugins used for checking the output of LLM (Language Model) in the context of programming. The author mentions that Claude 3.5 Sonnet is currently the preferred code for this purpose. However, the author also uses Continue Dev, Aider, and Claude Dev plugins, which are configured to use DeepSeek Coder V2 236B, including local ollama DeepSeek Coder V2 for tab completions. This configuration is chosen because it offers the best value at a cost of $0.14M/$0.28M, which is 43 times cheaper than Claude 3.5 Sonnet. The author also provides a leaderboard link from Aider, where Claude Dev plugin ranks just below Claude 3.5 Sonnet.

Total comment counts : 13
Summary
The article, written by John Holdun in 2021, offers ideas for designing a reliable and user-friendly web API. The author shares a rough draft and invites feedback.
Top 1 Comment Summary
The article discusses the benefits of resource-oriented design and Google’s API Improvement Proposals (APIs) in creating uniform and efficient application programming interfaces (APIs). The author recommends resource-oriented design as it helps avoid unnecessary debates about decision-making, such as the filter and pagination formats. The article also mentions that implementing the filter query parameter in GET requests can be challenging, especially for large tables, as it requires filtering the entire collection and creating appropriate predicates. The article provides two links for further reference.
Top 2 Comment Summary
The author appreciates a particular resource but feels that it lacks explanations for why certain recommendations are made. They argue that simply saying “do it because I say so” is not a sufficient justification when promoting good practices within a team. The author also warns against blindly following practices without understanding why they are considered good, as this can lead to ineffective architecture. They emphasize the importance of defining aesthetic changes on a system level and suggest that if there is disagreement, following the author’s suggestions is acceptable since these recommendations are already documented.
6. How the Hourglass Won
Total comment counts : 11
Summary
The article discusses the early days of Internet architecture and the competition among three competing visions for the future of networking. It mentions David Clark’s book “Designing an Internet” and how network architecture includes agreed-upon aspects like IP addresses while allowing flexibility in the design and implementation of specific networks. The article also discusses the collaboration between the author and Larry Peterson, as well as David Clark’s involvement in shaping the agenda for the National Information Infrastructure. The concept of the Internet architecture being pictured as an hourglass is introduced, and the article highlights the importance of considering the context in which this idea emerged.
Top 1 Comment Summary
The author dreams of a world that is more open to alternatives to IP (Internet Protocol), as they believe that the current IP system resists change. They express concern about IP’s lack of partition friendliness, as it requires devices to remain powered on and connected for instantaneous communication. This poses a problem in situations with limited resources. The author suggests that if software could tolerate reductions in service and offer more modes beyond instant or no communication, it would discourage governments from shutting it down and be more useful during infrastructure-damaging disasters.
Top 2 Comment Summary
The article discusses the concept of an hourglass design, which is a common pattern in various systems. It compares electricity and LLVM IR (Intermediate Representation) to an hourglass, as they both serve as intermediaries between different components. The author concludes that an hourglass design is unavoidable when trying to establish many-to-many non-coupled relationships.

The article discusses the quirks of vector searching, specifically with regards to returning unrelated paragraphs when searching for a certain word. The author mentions using a specific length for OAI text-embedding-3-large and states that each entry was around 1-2 paragraphs long. They go on to explain that for their recent project, they found that PGroonga was a more reliable option for full text document lookup, with fuzzy matching support.

8. Giving C++ std:regex a C makeover
Total comment counts : 12
Summary
The article discusses how to wrap the std::regex implementation in C++ standard library into a tidy C interface. The purpose is to hide the C++ machinery and make it usable in a C program. The C interface uses non-owning, counted string forms and arena allocation. The article also mentions that the regex library lives in its own Dynamic-Link Library with its own copy of the C++ standard library. It provides example usage and explains how to replace new and delete functions in the C++ side to allocate from the arena. The article also discusses handling exceptions and out-of-memory errors. The author also adds some extra flair by replacing delete functions.
Top 1 Comment Summary
The article explores the concept of writing C code without the C runtime in order to avoid dealing with it on Windows. The author treats it as a new language, using concepts like the string type and arenas to prevent memory bugs. The author finds it to be a cool hack and is inspired to write a regex library again.
Top 2 Comment Summary
The author of the article criticizes the performance of the gcc std::regex and mentions that they had to reimplement part of it using regex(3) because of its poor performance. They suggest that std::regex should be used only occasionally and not as part of a parser, as it is slow and can be broken. The author provides their own implementation in namespace dts as an alternative.
