The journey of a software engineer typically begins with learning a programming language, whether through formal education or self-teaching. As they progress, engineers often question how programming works, a valid inquiry that traces back many years. The origins of programming can be linked to ancient civilizations, but a significant milestone occurred in 1854 with George Boole's development of algebraic logic, which laid the groundwork for digital circuitry and programming. The modern era of coding began during World War II with the invention of programmable computers

ClangQL is a tool that enables users to execute SQL-like queries on C/C++ code rather than on database files, utilizing the GitQL SDK. It is important to note that all keywords in ClangQL are case-insensitive, akin to SQL. Additionally, building ClangQL from source or installing it via Cargo.io requires LibClang 17 to be installed. Feedback from users is taken seriously, and comprehensive documentation is available for all qualifiers.

The text discusses a group's recent cybersecurity exploits following their previous work with .MOBI domains, where they successfully issued TLS/SSL certificates for unregistered domains, leading to significant changes in domain ownership validation. Now, with a desire for further adventures, they introduce a new method they call "mass-hacking-on-autopilot." This involves exploiting abandoned backdoors in compromised systems to gain access without having to do the initial compromising work themselves. They liken this method to the practices of intelligence services collaborating

The blog post discusses the challenges of using LR parsing for programming languages, specifically with LR(1) and LR(k) grammars. While theoretically, any deterministic context-free language can be parsed using LR(1), creating an appropriate grammar can be difficult, often resulting in grammars that are hard to read and maintain. This loss of readability can lead to mistakes and complications when modifying the grammar. The author highlights the contrast between natural grammars, which are more intuitive, and encoded grammars that may

Vincent Bean is developing a project called 10MPage.com, which aims to archive the internet's state in 2025 by allowing users to upload 64x64 pixel images. The site plans to host 10 million of these images, leading to challenges in rendering them efficiently. Initially, Vincent experimented with using separate HTML `<img>` tags to display the images but encountered potential issues with performance. He then tested using a canvas approach, which provided more flexibility for features like loading animations and scrolling

The content discusses an experiment with "value-pooled" perfect hashing, where multiple keys can map to the same value, allowing for collisions. This approach aims to reduce the storage space needed for the hash table. The author encourages readers to explore the concept further, noting that the code for testing the experiment is available in a Jupyter notebook. Observations from running the optimal solution search for 64 keys and 2 values, averaged over 10 runs, are mentioned but not detailed in the summary.

The "range" of a force refers to the distance over which it can effectively produce significant effects. Long-range forces, like electric, magnetic, and gravitational forces, can influence objects over vast distances, even across rooms or galaxies. In contrast, short-range forces become negligible beyond a certain distance; for example, the weak nuclear force's effects diminish dramatically at distances smaller than an atom, leading to its designation as "weak." A schematic illustration shows how the strength of these forces varies with distance.
