The article discusses why C++ cannot be as "safe" as languages like Circle or Rust, even with extensive use of smart pointers. It highlights that the fundamental issue is the presence of internal raw pointers in types that programmers do not control. The author provides an example of an iterator invalidation mistake in `std::vector`, which results in a heap-use-after-free error. This occurs because when an element is added to a vector and it reallocates its storage, the existing iterators point to the

The content discusses a discussion between Robert "Uncle Bob" Martin and John Ousterhout about software design philosophies, specifically comparing Martin's "Clean Code" and Ousterhout's "A Philosophy of Software Design" (APOSD). Both authors recognize their differing views on certain aspects such as test-driven development (TDD) and abstraction. Ousterhout emphasizes that the primary goal of software design is to reduce complexity, making systems easier to understand and modify. He points out that the more information

The author discusses their intention to write a post about Pitchfork, beginning with a mental model related to HTTP/2. They address the common complaints about the lack of HTTP/2 support in Ruby HTTP servers like Puma, questioning the necessity of this feature and noting that they have not encountered a compelling use case for it. The author believes that exposing Ruby HTTP directly to the internet without a load balancer or reverse proxy is not worth the potential complications. They explain that HTTP/2 originated from SPDY

The post discusses a hypothesis from a French subreddit indicating that kebabs are worse the closer they are to train stations. The author, inspired by this idea and feeling aimless as a recently diagnosed autistic individual, decides to conduct an informal study to investigate the claim, focusing on kebab shops in Paris. They believe Paris provides ample data due to its density of train stations and kebab shops. Using OSMnx to analyze walking networks, they aim to explore the relationship between kebab quality and proximity to

Today, Claude 3.7 Sonnet1 was announced as the most advanced model to date, featuring hybrid reasoning capabilities. It allows for quick responses or detailed step-by-step thinking, with users able to control the duration of its thinking process. Notable improvements are seen in coding and front-end web development, accompanied by a command line tool called Claude Code for direct engineering task delegation. The model is accessible across all Claude plans and platforms, with pricing remaining the same as previous versions. A unique feature

The content describes a tiny data-over-sound library designed for transmitting small amounts of data between air-gapped devices using sound. It employs a simple Frequency-Shift Keying (FSK) transmission protocol, achieving bandwidth rates of 8-16 bytes per second. The library utilizes error correction codes (ECC) for better demodulation robustness and can interact with various audio backends. Examples of applications are listed, and a free waver application is available for testing the library. The encoding and decoding

A new preclinical study indicates that transplanting insulin-producing pancreatic islet cells alongside engineered blood-vessel-forming cells can successfully reverse type 1 diabetes in mice. Type 1 diabetes occurs when the immune system destroys insulin-producing islets, leading to insulin deficiency. While islet transplantation has shown promise, challenges remain in mimicking the blood-vessel-rich environment necessary for their survival. Researchers from Weill Cornell Medicine have developed a technique to transplant islets subcutaneously, which could potentially provide a

Vite is a widely-used build tool for developing JavaScript applications, particularly single-page apps. It features a "library mode" that allows users to publish their libraries on NPM. However, the author expresses dissatisfaction with how Vite's library mode handles dependencies. Specifically, when a library includes a dependency (like left-pad), Vite inlines the source code into the library's distribution instead of linking to it as a separate dependency in the `package.json`. This approach is criticized for reducing good

The content describes a self-hosted GitHub app named PRevent, designed to enhance security by preventing the merging of malicious code in pull requests. The app listens for pull request events and scans for malicious code, directly commenting on any detections. Unlike traditional security scans that can be bypassed, this app provides a more secure and flexible solution by ensuring scans cannot be manipulated. PRevent specifically detects dynamic code execution and obfuscation, which are common in malicious attacks but rare in legitimate code

Kyrylo Silin explains the usage of the underscore in the HTML target attribute, specifically target="_blank." Historically, developers used the `<frameset>` tag to create single-page application (SPA)-like experiences, where links could load content into specific frames. If a frame named "blank" was targeted but did not exist, the browser would open a new window instead. The underscore in target="_blank" serves to indicate that the link should open in a new tab, eliminating confusion with frame names

OpenAI researchers have acknowledged that their advanced AI models, including GPT-4o, are currently inferior to human coders, despite CEO Sam Altman's optimism that they might surpass "low-level" software engineers by the end of the year. A recent study using the SWE-Lancer benchmark, which evaluates performance on over 1,400 software engineering tasks from Upwork, showed that these models struggle to solve the majority of coding tasks. The models were tested on two types of tasks: fixing bugs and

The author is undertaking the ambitious project of creating a personal implementation of Apache Kafka called MonKafka. Initially, they successfully enabled message production and consumption through a subset of Kafka's protocol. However, the real challenge lies in developing a distributed system that is scalable, resilient, and consistent, capable of handling massive data volumes. Historically, Apache Kafka relied on Zookeeper for state management and cluster coordination. This was replaced by Kraft, which integrates these functions directly within Kafka using the Raft consensus algorithm. The
