Typesetting is likened to "architecture in two dimensions," where text and fonts serve as the building materials, and typesetting itself represents the architectural drawings. It's a complex field encompassing both art and engineering, particularly influenced by digital advancements. One key element in typesetting is the typesetting engine, which is software that determines the layout of text and visuals for print or digital formats. The author addresses queries about the choice of LaTeX as the default typesetting engine for PPResume, acknowledging the complexity

Tim Coates expresses his deep affection for the Pascal programming language, including its variants like Delphi, Free Pascal, and Lazarus. Despite its lack of popularity in discussions about programming languages—often overshadowed by C, Python, and modern JavaScript frameworks—Coates believes Pascal remains relevant and valuable, especially for beginners. He highlights Pascal's clarity and readability, making it an effective language for understanding programming fundamentals such as variables, loops, and control structures without the complexities found in more trendy languages. However

The content discusses the mixed feelings developers have towards JavaScript, despite its widespread use—62% report using it, but only 58% admire it. Notably, a proposal led by Google engineer Shu-yu Guo aims to split JavaScript into two: a core version (JSO) and a more feature-rich version (JSSugar) that would require additional tools. The intention is to simplify the core JavaScript and reduce complexity while allowing for experimental features through JSSugar. While

The DownloadManager class in qBittorrent has ignored SSL certificate validation errors for over 14 years, up until October 12, 2024, when the default behavior changed to include verification. The first patched version, 5.0.1, was released recently. This oversight affected numerous functionalities, including searches and RSS feeds, allowing all certificate types (expired, self-signed, etc.) to be accepted. Additionally, since June 2015, if a Windows user lacks a

The content discusses challenges faced in programming with incomplete code, such as blank spots, type errors, and merge conflicts, which lack formal definitions in conventional programming language definitions. This absence leads to a lack of live feedback on completed portions of programs, forcing tools to use complicated heuristics for language services like code completion and type inspection. To address this, the authors are developing a new approach grounded in contextual modal and gradual type theory, treating incomplete programs as those with "holes" that signify missing parts or errors

An editorially independent publication supported by the Simons Foundation highlights recent discussions about detecting gravitons, the hypothetical particles responsible for gravity. Currently, conventional methods suggest that capturing a graviton is nearly impossible; for instance, an Earth-size apparatus would only detect one every billion years. However, a new proposal suggests a method that combines gravitational wave research and advancements in quantum technology, making graviton detection more feasible. While still a challenging endeavor, the proposed experiment could potentially be conducted in a modest laboratory setup over

Polipo is often labeled simply as a "code generator," which can lead to misunderstandings about its capabilities. While it does generate code, Polipo distinguishes itself from other AI-powered tools by functioning more like a compiler rather than just producing code for manual editing. This realization came slowly, as the concepts of "Figma," a design tool, and "compiler," typically associated with coding, appear vastly different. Ultimately, Polipo's unique role as the first Figma compiler means that it effectively transforms
