The Stack Exchange network includes 183 Q&A communities, with Stack Overflow being the largest platform for developers to learn and share knowledge. It now offers AI features for workplace collaboration through Stack Overflow for Teams, enabling users to ask questions, find answers, and connect easily. A common practice in programming tutorials is the use of placeholder names "Foo" and "Bar." These terms originated from a WWII acronym, FUBAR, meaning "F-ed Up Beyond All Recognition." Such acronyms gained popularity during military

ChatGPT has launched a canvas capability that enhances the generation and viewing of structured content, but it currently does not support direct previews of HTML or SVG code. To address this, a bookmarklet has been created to enable quick previews of HTML content directly in the browser. Users can copy code from ChatGPT or Claude and use the bookmarklet to view it as a live HTML page without needing to use an IDE or refresh a page. The bookmarklet also supports SVG graphics, making it useful for web development

Nintendo has succeeded in shutting down the Ryujinx emulator following its earlier victory over Yuzu, which also ceased development after a legal settlement. Ryujinx's lead developer, gdkchan, reportedly agreed to halt the project and remove associated assets after being contacted by Nintendo. This move underscores Nintendo's aggressive legal approach towards emulation and raises concerns about the future of the emulation community and game preservation efforts. The shutdown has resulted in the removal of Ryujinx’s download page and its GitHub

The content discusses benchmarking and comparing the performance of hashmaps and ordered data structures, specifically b-trees, in various scenarios. Many scripting languages use hashmaps for associative data structures, but they come with disadvantages. B-trees, while typically slower than hashmaps, present varying performance expectations among users. The author conducts benchmarks to compare these data structures by measuring lookup times of randomly generated integers. Initial tests showed b-trees performing significantly worse than hashmaps. A subsequent benchmark changes the approach by averaging over

SzamlaBridge and PlaceOfCards, two projects that utilized Firebase, encountered challenges such as difficult schema migrations and query limitations. To address these issues, they migrated to Supabase, which resolved their problems and provided valuable learning experiences, despite the tedious nature of migration. The text discusses common misconceptions about NoSQL databases, emphasizing that while these databases can be beneficial, they may not be suitable for small teams or startups that frequently change data and requirements. The process of “joins” in NoSQL involves

Octothorpes refer to hashtags and backlinks used across the web to link various URLs and resources, allowing for a decentralized approach beyond commercial platforms. Octothorpe servers function similarly to web rings and blog rolls, serving as searchable feeds that small communities can manage independently. To participate in an Octothorpes Ring, a domain must be verified and registered, which helps manage spam and other unwanted content. Registration involves adding a unique verification code to the domain's DNS records. After verification, domains can

The article discusses how major services like AWS and Netflix achieve fast response times despite complex architectures involving numerous microservices. The key to their efficiency lies in caching, which can significantly improve system scalability by reducing the need for repetitive database queries that slow down response times. Caching allows for the storage and reuse of responses, which eases the load on the system, especially for high-traffic scenarios, such as a large news website. To provide a thorough understanding of caching, the content is divided into two

The SQLite library is consolidated into a single large C file named "sqlite3.c," known as "the amalgamation," which simplifies deployment by reducing the complexity of file management. The amalgamation enhances performance, allowing for better compiler optimizations, resulting in machine code that is 5% to 10% faster. As of version 3.37.0 (November 2021), the SQLite library comprises 133 source files—111 are C code files, and 22 are C header files

The article compares the performance of two rich text editors, Lexical and ProseMirror, under data load over time. The findings indicate that Lexical is faster and more responsive for short-term use, but its performance declines significantly during prolonged heavy use, likely due to poor memory management. In contrast, ProseMirror, which is better suited for long-term usage, offers slower initial responses but exhibits more stable and predictable performance over time. ProseMirror, created by Marijn Haverbeke,

The content describes "sq," a free and open-source data wrangling tool that functions like a Swiss army knife for data inspection, querying, joining, importing, and exporting. It is compared to "jq" for databases and documents, and its query language (SLQ) is pronounced like "sleek." Users can begin with `sq help` and access detailed documentation, including tutorials and guides. Key features include: - Using the `diff` command for comparing source metadata or row values.

The author critiques the current state of software development in 2024, highlighting an over-reliance on complex architectures like microservices and various technologies that prepare for large-scale usage, which may not be necessary for most projects. Instead of building with expansive scale in mind, the author advocates for starting small and using vertical scaling, as modern hardware can handle substantial workloads on a single server. They suggest that many applications fail to gain traction and thus don't require excessive infrastructure from the start. Optimizing for flexibility

The post is aimed at SIMD CPU programmers interested in unique AVX instructions, particularly veterans of Amiga programming who struggled with calculating the “minterm” blitter value. Inspired by a talk on the AVX-512 Instruction Set Architecture by Tom Forsyth, the author highlights the vpternlogd instruction, which performs bitwise ternary logic operations using three input sources and can operate on 512-bit registers. The efficiency of vpternlogd lies in its ability to execute complex logic operations with

The content discusses the simplicity of the HTTP protocol, emphasizing that it consists of a request line, headers, and a message body. An example in Go demonstrates how an HTTP server handles requests and responses, specifically highlighting the "Content-Length" header, which indicates the length of the response body. The Go code illustrates that headers are automatically managed when sending responses, and highlights potential issues when dealing with response size. It raises a question about how a server can know the size of a response before sending it,

The discussion explores the misconception that server-side JavaScript is merely a resurgence of PHP. Instead, it argues that the evolution from PHP to modern full-stack JavaScript frameworks represents significant progress in web development. The author reflects on the simpler times of using PHP and other server-side languages to create basic web applications, emphasizing that those earlier frameworks did not support the complexity of today's applications. They highlight the past reliance on JavaScript for enhancing interactivity and the challenges posed by early versions of the language. Overall,

The Book of Kells, celebrated as one of Ireland's greatest cultural treasures, distinguishes itself from other medieval illuminated manuscripts due to its exceptional artwork and numerous illustrations across its 680 pages. Crafted in the Hiberno-Saxon style, it is believed to have been created around 806 on the island of Iona and later moved to Kells in County Meath after a Viking raid. The manuscript primarily features the four gospels and canon tables, designed mostly for display rather than for reading aloud,

The author shares their insights on improving artistic skills, emphasizing the importance of a supportive teacher or group, practicing daily—even just for 15-30 minutes—and striving to improve oneself continually. They argue that perceived "talent" in the arts often results from extensive practice rather than innate ability, citing their own experiences and those of talented peers who dedicated significant time to their craft. The author encourages persistence and self-competition in the pursuit of artistic growth. They also provide links to their own artistic journey and
