The author of the open-source Discord bot Simplex shares their journey in developing the bot, which started on October 15, 2021, initially as a Python tutorial project. Over time, it evolved into a community-focused tool with 84,000 users across 500 servers. The bot aims to provide an alternative to expensive bots like Mee6, which upset the author due to hidden charges that exploit younger users. As Simplex grew, the author recognized the need for some income to support hosting

The author humorously comments on the contrasts between complex functional programming languages and Ada, a government-oriented language from 1983, particularly in the context of dependent types. While languages in the former group often delve into advanced concepts, Ada's documentation overlooks such theory in favor of practical application. The author, who is not well-versed in functional programming or type theory but has skills in Ada, decides to explain how Ada employs dependent types. Dependent types are defined as those that rely on specific values,

A user is experiencing an issue with a newly acquired NVMe drive on their MSI PRO X670-P WIFI motherboard. Although the drive works perfectly in other systems, it only functions correctly on the MSI board for one power cycle after installation. After turning off the computer, the drive fails to be detected until it is physically removed and reinserted. The user has ruled out CPU issues since they replaced the CPU without effect. They suspect it might be a BIOS problem, while MSI attributes the issue to the

The content discusses Mixin, a Java framework that uses ASM for bytecode weaving and trait/mixin implementation. It hooks into the runtime classloading process and currently supports Mojang's deprecated LegacyLauncher system, favoring the more extensible ModLauncher. Documentation for Mixin is available in a Wiki and Javadoc, and users can seek help on the Sponge Discord Server. Mixin provides binaries through Jenkins and maven repositories, and an Annotation Processor to generate obfuscation mappings. For Gradle

Jan Pieter Bruins Slot shares his experience of working on an assignment for creating a concurrent webserver while studying "Operating Systems: Three Easy Pieces." He decided to implement a webserver from scratch to enhance his understanding of socket programming and document the process for others. The post outlines the step-by-step creation of a simple webserver in C, beginning with an overview of webserver functionality. A webserver's primary role is to handle client requests over HTTP and deliver files, functioning as either a static or dynamic

The content discusses covert discrimination, which often targets individuals rather than identifiable minority groups, making it difficult to detect. This type of discrimination occurs subtly within communities, such as the Ruby Community, where some individuals may be treated poorly despite the overall positive treatment of the majority. To address this issue, the author has created a guide to help identify covert discrimination, based on their experiences in Canadian and US software development companies. The guide highlights forms of covert discrimination, including: 1. **Selective Treatment**:

Frostie314159 and Jasper Devreker presented a project at 38c3 focused on reverse engineering the Wi-Fi peripheral of the ESP32 to create an open-source Wi-Fi stack. They noted that, although the existing closed-source stack operates effectively, an open-source alternative would provide enhanced capabilities for modification and auditing, especially concerning sensitive data. Their work highlighted the ESP32's versatility for research and IoT applications, including its potential as a pentesting tool, B.A.T.M.A.N

The content discusses the development of a Minecraft server called "CobolCraft," which is written in COBOL and supports Minecraft version 1.21.4. The server has some functional features, although the implementation of complex block behaviors is limited due to the challenges of COBOL. CobolCraft is built with GnuCOBOL and is primarily designed for Linux, with Docker available for cross-platform deployment. To set it up on Linux, users must install prerequisites and run make commands, while configuration

The MODEL 777 project originated in a high school architecture class where the creator initially used manila file folders to model building ideas. Inspired by the versatility of paper, the creator decided to challenge themselves by modeling a Boeing 777 airplane. Starting in mid-2008, the project has undergone multiple revisions, evolving into a detailed representation of the aircraft. To ensure accuracy, the creator gathers source material, including photos, videos, and technical drawings. This research aids in understanding the shape and function of each

The author shares their experience with Advent of Code, a yearly event in December that involves solving daily programming puzzles inspired by Christmas-related themes. This year’s focus was on locating the Chief Historian, linking the event to notable moments from past years. The author, originally from Germany, draws a parallel between Advent of Code and traditional Advent Calendars, which typically contain chocolates to celebrate the countdown to Christmas. They appreciate Advent of Code as an opportunity to fill gaps in their computer science knowledge, particularly in areas

In Python, exceptions can be linked to provide clarity about errors through the `raise [Exception] from [cause]` syntax. This feature helps to show the relationship between exceptions when one occurs during the handling of another. However, it may sometimes clutter stack traces and make them harder to comprehend. To address this, Python offers `raise Exception from None`, allowing developers to suppress exception chaining, resulting in simpler and clearer stack traces. By default, when an exception occurs in an `except` block

The content emphasizes the importance of user feedback and describes a feature for checking version upgrades when updating a repository. This feature prevents the creation of a new release with an outdated version in the code. Users can pass an optional regex for version strings and must specify a filename containing the version to verify updates. The default regex is /[v]\d.\d.\d/ (e.g., v1.0.0), and users can test their regex formats on rubular.com. Additionally, it provides

In September 2023, Ruby introduced Gem::SafeMarshal to enhance the safety of deserialization when processing .gem files. This feature can be accessed via `rubygems/safe_marshal` or `Gem.load_safe_marshal`, and offers two methods: `safe_load` (with a limited, hardcoded list of permitted items) and `load` (which allows the specification of permissible classes and symbols). The implementation posed challenges, as Ruby's Marshal does not provide built-in restrictions like

The blog discusses the concept of "confident LLMs" (large language models) and their tendency to express certainty even when they produce incorrect information, also known as hallucinations. This confidence is attributed to the instruction tuning process that models undergo after initial training. The writer mentions a prior experiment ranking Hacker News users based on their suitability for a software engineering role and notes that less sophisticated models typically hesitate to make definitive choices, often asserting that both options are equally good or bad. This raises the question

The content discusses best practices for building an effective caching system for backend web applications, focusing on API response caching with JSON and using Redis. Key points include: 1. **Cache Structure**: Instead of a single cache for all data (like shopping cart, order status, and user profile), it's beneficial to split the cache into separate entities. This reduces the number of cache invalidations and improves the cache hit ratio, as more stable data (like user profiles) won’t be invalidated by frequent changes
