Dockerfmt is written in Go and can be installed as a standalone binary or used as a library.
curl-impersonate is a specialized version of curl designed to mimic the behavior of popular web browsers like Chrome, Firefox, and Safari. It achieves this by accurately replicating their respective User-Agent strings, TLS fingerprints (including cipher suites and supported protocols), and HTTP header sets, making it a valuable tool for web developers and security researchers who need to test website compatibility and behavior across different browser environments. It simplifies the process of fetching web content as a specific browser would, allowing users to bypass browser-specific restrictions or analyze how a website responds to different browser profiles.
Hacker News users discussed the practicality and potential misuse of curl-impersonate. Some praised its simplicity for testing and debugging, highlighting the ease of switching between browser profiles. Others expressed concern about its potential for abuse, particularly in fingerprinting and bypassing security measures. Several commenters questioned the long-term viability of the project given the rapid evolution of browser internals, suggesting that maintaining accurate impersonation would be challenging. The value for penetration testing was also debated, with some arguing its usefulness for identifying vulnerabilities while others pointed out its limitations in replicating complex browser behaviors. A few users mentioned alternative tools like mitmproxy offering more comprehensive browser manipulation.
This project introduces "sortashuffle," a tool designed to shuffle a list of TV shows (or other media) while maintaining the intended viewing order within each show. It accomplishes this by treating each show as a group, shuffling the order of the shows themselves, but keeping the episodes within each show in their original sequence. This allows for a randomized viewing experience while still preserving the narrative flow of individual series. The implementation uses Python and provides command-line options for customizing the shuffling process.
Hacker News users discuss the practicality and limitations of the "sortashuffle" tool, which shuffles items while preserving original order within groups. Some highlight its usefulness for playlists or photo albums where related items should stay together. Others point out that true randomness isn't achieved, with the algorithm simply rearranging pre-defined chunks. Several suggest alternative approaches for achieving similar results, such as shuffling album lists and then tracks within each album, or using a weighted shuffle based on metadata. The discussion also touches on the definition of "shuffle" and the user experience implications of different shuffling methods. A few users delve into the specific algorithm, suggesting improvements or noting edge cases.

Xan is a command-line tool designed for efficient manipulation of CSV and tabular data. It focuses on speed and simplicity, leveraging Rust's performance for tasks like searching, filtering, transforming, and aggregating. Xan aims to be a modern alternative to traditional tools like awk and sed, offering a more intuitive syntax specifically geared toward working with structured data in a terminal environment. Its features include column selection, filtering based on various criteria, data type conversion, statistical computations, and outputting in various formats, including JSON.
Hacker News users discuss XAN's potential, particularly its speed and ease of use for data manipulation tasks compared to traditional tools like awk and sed. Some express excitement about its CSV parsing capabilities and the ability to leverage Python's power. Concerns are raised regarding the dependency on Python, potential performance bottlenecks, and the limited feature set compared to more established data wrangling tools like Pandas. The discussion also touches upon the project's early stage of development, with some users interested in contributing and others suggesting potential improvements like better documentation and integration with other command-line tools. Several comments compare XAN favorably to other similar tools like jq and miller, emphasizing its niche in CSV manipulation.
Httptap is a command-line tool for Linux that intercepts and displays HTTP and HTTPS traffic generated by any specified program. It works by injecting a dynamic library into the target process, allowing it to capture requests and responses before they reach the network stack. This provides a convenient way to observe the HTTP communication of applications without requiring proxies or modifying their source code. Httptap presents the captured data in a human-readable format, showing details like headers, body content, and timing information.
Hacker News users discuss httptap, focusing on its potential uses and comparing it to existing tools. Some praise its simplicity and ease of use for quickly inspecting HTTP traffic, particularly for debugging. Others suggest alternative tools like mitmproxy, tcpdump, and Wireshark, highlighting their more advanced features, such as SSL decryption and broader protocol support. The conversation also touches on the limitations of httptap, including its current lack of HTTPS decryption and potential performance impact. Several commenters express interest in contributing features, particularly HTTPS support. Overall, the sentiment is positive, with many appreciating httptap as a lightweight and convenient option for simple HTTP inspection.
Sniffnet is a cross-platform network traffic monitor designed to be user-friendly and informative. It captures and displays network packets in real-time, providing details such as source and destination IPs, ports, protocols, and data transfer sizes. Sniffnet aims to offer an accessible way to understand network activity, featuring a simple interface, color-coded packet information, and filtering options for easier analysis. Its cross-platform compatibility makes it a versatile tool for monitoring network traffic on various operating systems.
HN users generally praised Sniffnet for its simple interface and ease of use, particularly for quickly identifying the source of unexpected network activity. Some appreciated the passive nature of the tool, contrasting it with more intrusive solutions like Wireshark. Concerns were raised about potential performance issues, especially on busy networks, and the limited functionality compared to more comprehensive network analysis tools. One commenter suggested using tcpdump or tshark with filters for similar results, while others questioned the project's actual utility beyond simple curiosity. Several users expressed interest in the potential for future development, such as adding filtering capabilities and improving performance.
