The text emphasizes the importance of adhering to the LGPL (Lesser General Public License) when using the LGPL-licensed libdiscid library. It highlights that while feedback is valued and users can contact maintainers through GitHub, the provided version of libdiscid missed including the required license file, which constitutes a violation of LGPL. Additionally, it points out that the omission of build tools and scripts hinders the proper linkage to the modified version of the library, constituting a significant modification that necessitates

On June 11, 2024, vulnerabilities were discovered in Kia vehicles that allowed remote control of key functions using only a license plate. These exploits could be executed in about 30 seconds, regardless of whether the vehicle had an active Kia Connect subscription. Attackers could access personal information, such as the owner's name, phone number, and address, and could add themselves as a hidden second user of the vehicle without the owner's knowledge. Although a demonstration tool was created to illustrate these vulnerabilities, it was

Samuel from Enginuity discusses the issue of knowledge silos in the Tech Leadership track, highlighting their detrimental impact on engineering productivity. According to a StackOverflow survey, 30% of developers feel that knowledge silos affect their productivity multiple times a week, with 45% reporting negative impacts on idea sharing and collaboration. Knowledge silos occur when information and expertise are confined to specific teams or individuals due to poor processes, lack of communication, or a sense of ownership over information. This leads to slower

The content contrasts two types of tech professionals: generalists and specialists. Generalists are adaptable, possessing a broad range of skills across various areas (e.g., programming languages, UI/UX, and architecture), making them valuable in startup environments where they can prototype ideas, pivot when necessary, and fill multiple roles. They are often seen in leadership positions due to their holistic understanding of tech ecosystems. On the other hand, specialists focus intensely on specific fields such as AI or database technology, driving innovation and

Wafris, an open-source web application firewall company, is releasing version 2 of its Rails client, which now uses SQLite instead of the previously required Redis datastore. This article discusses the shift from Redis to SQLite, highlighting the performance considerations and architectural changes that led to this decision. The initial choice of Redis was influenced by its ease of use in the Heroku ecosystem, but feedback from users revealed many experienced difficulties in deploying and managing Redis, which complicated the user experience. The transition to SQLite aims

The author compares the Rust programming language to the first-generation iPhone, noting its initial appeal due to features like algebraic types and memory safety, but expressing disappointment over its slow progress and lack of new features in recent years. After four years of using Rust, the author feels it has not fully realized its potential, with many proposed features, such as coroutines, remaining unimplemented despite being available in the compiler. The author attributes this stagnation to the inability of Rust's consensus process to scale effectively

The `cronexpr` library is designed for parsing and operating on crontab expressions. It supports standard crontab syntax as well as many non-standard extensions, with the key distinction that it requires a timezone to be specified in the expression for accurate timestamp determination. The library can interpret various formats for month and day values (both numerical and abbreviated names) and supports wildcard (*) for indicating "all", hyphens (-) for defining ranges, and slashes (/) for specifying step values.

Over the past seven years, the author has focused on improving concurrency, scalability, and interactivity in the Ruby ecosystem. They released Async in 2017, a framework for concurrent Ruby applications, but it initially required wrappers for blocking operations, limiting its compatibility. To solve this, they developed the fiber scheduler, introduced in Ruby 3.1 and Async 2 in 2021, which allows existing Ruby code to run concurrently by redirecting blocking operations to an event loop. In response to the

The text discusses a tool called "git absorb," which automates the process of creating fixup commits for identified bugs in a feature branch without resorting to opaque commits or manual interactive rebases. It helps maintain atomic commits by automatically associating staged changes with the correct previous commits. Users can then integrate these fixup commits into their branch using the --and-rebase flag or review the changes manually. The tool can be installed from the latest tagged release artifacts available for Windows, MacOS, and Linux

The post discusses how to share a Llama model running on a Mac with other computers on the same local network for privacy and cost efficiency. It highlights that Apple silicon (M1, M2, etc.) performs well for this purpose, and the default Llama3.1:8b model runs effectively on a Mac Mini M1 with 16GB of RAM, while simpler models may be needed for 8GB systems. The process begins with installing Ollama on the Mac, followed by

The author, a software engineer and musician, explores the performance differences between using procs, lambdas, and blocks in Ruby. After some research, the author conducts performance tests using the Benchmark module and finds that blocks generally should be faster but their method-calling overhead can negate this speed advantage when using them in certain ways. The author initially set up the tests with a large number of iterations and realized that direct passing of procs and lambdas is more efficient than calling the method repeatedly with blocks.

Memory safety vulnerabilities pose a significant threat to software security, and at Google, the solution lies in adopting Safe Coding practices that emphasize a transition to memory-safe languages. This approach not only addresses new code but also reduces overall security risks in existing codebases, ultimately leading to a notable decline in memory safety vulnerabilities. For example, data on Android shows that the percentage of these vulnerabilities decreased from 76% to 24% over six years due to a shift towards memory-safe languages. Even in a growing code

In a recent article, a Data Scientist at Wallapop shares their journey of building a simple search engine from scratch using Python. The motivation behind this project stems from the "Small Website Discoverability Crisis," a challenge where small websites struggle to be found on popular search engines like Google. The author aims to enhance the visibility of these lesser-known sites by creating a straightforward search engine that demonstrates the underlying mechanics of search technology. Although the engine consists of approximately 80 lines of code, the complete project,
