RISC OS 3.11 GUI: A Retrospectively Advanced Desktop

2025-05-18

This article delves into the unique graphical user interface (GUI) of RISC OS 3.11, released in 1992 by Acorn Computers. Unlike contemporaries like Apple's System 7, RISC OS 3.11 featured a distinct desktop layout with a Pinboard and Icon Bar, innovative three-button mouse interactions, and a menu system seamlessly integrating dialog boxes. Its unconventional approach to window management, including focus and stacking order, along with its drag-and-drop file handling and custom file type support, stands out. The system's intelligent use of mouse buttons reduced keyboard modifier reliance. RISC OS 3.11's GUI remains a fascinating example of unconventional design that offers valuable lessons even today.

Bye Bye, Paid Note-Taking Apps: Building My Secure & Private Knowledge Vault

Tired of privacy concerns and high costs associated with commercial note-taking apps, the author decided to build their own secure, private, and lasting Personal Knowledge Management System (PKMS). They share their journey from Obsidian to a self-hosted PKMS, emphasizing data security and control. The system uses the open-source platform Directus and stores notes in Markdown, enabling easy cross-device access and data migration. While seemingly complex, the author argues the process is surprisingly simple and encourages others to build their own knowledge vaults for better knowledge management.

Spaced Repetition: Mastering Memory with the Power of Algorithms

2025-05-18

Spaced repetition systems (SRS) leverage the testing and spacing effects to dramatically improve memorization. SRS, pioneered by Supermemo and popularized by Piotr Wozniak, goes beyond rote learning, facilitating conceptual understanding. These systems make remembering a deliberate process, not just chance, and are proven remarkably effective for retaining vast amounts of information.

Working with Git Patches in Apple Mail: A Surprisingly Simple Workflow

2025-05-18

This guide details how to manage Git email patches within Apple Mail on macOS. First, create a dedicated 'Patches' mailbox. Move emails containing patches into this mailbox and export it to a local folder. Finally, use the `git apply` command in your terminal to apply the patch. While this simplifies the process in Apple Mail, the actual patch application happens via the terminal. Remember to regularly clean up your local 'Patches' folder.

Microsoft Finally Fixes Security Update That Broke Dual-Booting

Last August, a security update intended to address a GRUB bootloader vulnerability inadvertently broke dual-booting Windows and Linux on Secure Boot-enabled systems. This vulnerability allowed malicious actors to bypass Secure Boot's safety mechanisms. Nine months later, on May 13, 2025, Microsoft quietly released a patch (KB5058385) to fix the issue. The patch mitigates problems by refining how Secure Boot Advanced Targeting (SBAT) interacts with dual-boot systems, preventing legitimate Linux bootloaders from being blocked and avoiding "Security Policy Violation" errors. The fix applies to Windows 11 23H2, 22H2, 21H2; Windows 10 21H2; and Windows Enterprise 2015 LTSB, Windows Server 2022, 2019, 2016, 2012, 2012 R2. The patch is automatically applied via Windows Update.

Decision Trees: A Divide-and-Conquer Approach to Machine Learning

This is the first in a series exploring decision trees in machine learning. Decision trees recursively partition data into regions based on a series of questions, ultimately leading to a prediction. The article clearly explains the mathematical definition of decision trees, the types of decision trees (classification and regression), common algorithms (ID3, C4.5, and CART), and objective functions (Gini impurity, entropy, and squared loss). It also delves into the pros and cons, bias-variance tradeoff, the "staircase effect," and the greedy algorithm used to build decision trees.

Fearless Concurrency in Python: The Lungfish Project

2025-05-18

The Project Verona team is developing Lungfish, a novel ownership model for Python designed to provide safe and efficient memory and concurrency management. They initially prototyped region-based ownership concepts using a toy language, FrankenScript, and shared their findings with the Faster CPython team. Currently, they're incrementally implementing a deep immutability model, including deep immutability in CPython, managing cyclic immutable garbage, and integrating with inter-subinterpreter messaging. This will pave the way for applying the region-based ownership model to Python, ultimately aiming to simplify concurrent programming and avoid concurrency pitfalls. The project draws heavily from languages like Rust but employs dynamic checks to accommodate Python's dynamic typing.

Programming Languages and Their Killer Domains

2025-05-18

An article argues that every programming language needs a killer app to succeed. The author proposes a refinement: instead of a 'killer app', it's more accurate to say a 'killer domain'. Examples include C for kernels, C++ and Rust for low-level systems programming, Java for business applications and Android, Python for scientific computing and machine learning, and JavaScript for web frontends. The author's experience shows that using a language outside its area of expertise is significantly harder and often impractical.

Expert vs. Novice: Efficiency in Problem Solving

This essay uses the analogy of a maze to illustrate the stark difference in efficiency between experts and novices in problem-solving. Experts, with their experience and efficient strategies, navigate challenges swiftly. Novices, however, often get bogged down in self-created complexities, wasting time on irrelevant tasks. The author emphasizes that novices aren't inherently less capable but lack experience and a holistic view of the problem. Novices need expert guidance to identify crucial decisions and avoid cascading errors from poor choices. They should actively explore the field, cultivate confidence, and embrace challenges.

Fortran for C Programmers: A Quick Start Guide

2025-05-18

This concise guide provides essential information for C/C++ programmers to quickly get started with Fortran. It covers key aspects of the language, including its two source forms (fixed-form and free-form), implicit typing rules, built-in functions, modular programming, and input/output operations. The guide highlights differences between Fortran and C/C++ in data types, arrays, pointers, and function calls, and points out potential pitfalls, such as operator precedence and short-circuiting evaluation. This is a great starting point for C/C++ programmers interested in learning Fortran.

Stream vs. Batch: It's Actually About Push vs. Pull

2025-05-18

The common "Stream vs. Batch" debate is misleading. Many streaming systems internally use batching for performance, but the real distinction lies in data processing semantics: 'push' systems deliver data in real-time, providing a complete, up-to-the-second view; 'pull' systems periodically query data, potentially missing updates and deletes. While 'push' is more complex, its real-time advantage is compelling. Once you experience the magic of second-level data freshness, you won't want to go back. In practice, both approaches complement each other, with batch processing often used for backfilling in otherwise streaming systems.

Stack Overflow Rebrands Amidst AI-Driven Traffic Plunge

Facing a dramatic 64% drop in traffic due to AI-powered alternatives, Stack Overflow's parent company, Stack Exchange, is undertaking a rebranding initiative. Despite continued profitability, the decline in user engagement presents an existential threat. The company aims to shift from a single Q&A focus to a three-pillar model encompassing community, careers, and Q&A, while also developing AI-assisted tools and improving its recruitment services. This move has sparked user debate, with some arguing that rebranding isn't the solution and the current platform is sufficient.
