My work is primarily in Microsoft’s ecosystem, so learning Copilot usage in VS Code is pretty important. If not for my own productivity gains, then for having knowledgeable conversations with coworkers about using LLMs as a SWE. Copilot-Powered Scenarios AI Code Completions I’ve found code completions more distracting than useful. Probably because I already have an idea of what I want to type, and Copilot’s hallucinations slow me down....

As the web evolves, where do practitioners congregate and exchange ideas? Working Groups develops standards and guidelines to help everyone build a web based on the principles of accessibility, internationalization, privacy and security. publishes standards and drafts , which are then implemented by browser vendors, e.g., Chromium, Firefox, and Safari. Topics of interest: accessibility, browser, CSS, data, DOM, digital publishing, graphics, HTML, HTTP, internationalization, media, performance, privacy, protocol, security, web API, web fonts, Web of Things (WoT), and XML....

Clang, LLVM, GCC, and MSVC LLVM is an umbrella project, with several sub-projects, e.g. LLVM Core and Clang. LLVM Core libraries provide an optimizer and code generator for different CPUs. Clang is an “LLVM native” C/C++/Objective-C compiler which aims for fast compilation, useful error and warning messages, and a platform for building source-level tools. The Clang Static Analyzer and clang-tidy are examples of such tools. So if I were to create a programming language, I can define a transformation into LLVM intermediate representation (LLVM IR), and that will make use of LLVM core to optimize it?...

Bloom Filters In true fashion to Stigler’s Law of Eponymy (no scientific discovery is named after its original discoverer ), Ross Ashby (1960) did a probabilistic analysis of Calvin Mooers’s Zatocoding (1947) (coding system for library cards). This predates Burton Bloom’s work (1970). Motivation A Bloom filter for a set \(X: \{x_1, x_2, …, x_n\} \) from some universe \(\mathbb{U}\) allows one to test whether a given item \(x \in \mathbb{B}\) is an element of \(X\)....

Debugging 101 Definition? Debugging involves inspecting a program’s internal state. printf Debugging and Logging In printf debugging, one adds print statements and keeps iterating until enough information has been extracted. Using logging has several advantages over printf debugging: varying logging destinations (e.g. standard output, files, sockets, remote servers, etc.); severity levels (e.g. INFO, DEBUG, WARN, ERROR, &c) that support filtering of output; color-coding for readability. Terminals have varying levels of color support: plain color; ANSI escape codes (16 color codes with bold/italic and background); 256 color palette; 24-bit truecolor (“888” colors, aka 16 million, e....
