The blog discusses the evolution of databases from the 1970s to the present, particularly focusing on the concept of Hybrid Transactional/Analytical Processing (HTAP). Initially, databases like Oracle V2 and IBM DB2 handled both OLTP (transactional) and OLAP (analytical) workloads on the same system. However, as data volumes grew, this dual functionality strained the systems because transactional and analytical demands are fundamentally different—OLTP requires fast inserts and lookups, while OLAP

In a May 2025 article, Graphite discusses their approach to building developer tools, emphasizing the importance of architecture decisions on development speed and quality. The founders opted for a monorepo structure using TypeScript, avoiding microservices and distributed systems to reduce complexity and improve developer velocity as they scaled from a small team to 40 engineers. They identified three major sources of software complexity: change amplification, cognitive load, and unknown dependencies. While acknowledging the benefits of microservices for team autonomy, Graphite

The author will be speaking at Systems Distributed next month, introducing new formal methods mental models for mainstream software development, although this added commitment will lead to only minor updates in the next two monthly releases of "Logic for Programmers." They discuss an article titled "Against Curry-Howard Mysticism," which prompts a desire for clarity on mathematical concepts like "undecidable." The author shares a technical definition of decidability from the book "Automata and Computability," explaining it in simpler terms for programmers.

The author discusses their exploration of multithreading by implementing it in an NES emulator, specifically with Super Mario Bros. They draw an analogy between threads and emulator save states, highlighting the potential for using this concept as a teaching tool. In their version, three distinct instances of the game run concurrently, with the emulator switching between them at regular intervals (every 160 frames). Each thread is given a unique color palette, resulting in a dynamic visual effect as the game instances alternate. The process involves creating save

The principle of "Don't Repeat Yourself" (DRY) is a foundational concept in programming that encourages developers to eliminate code duplication. However, the article warns that prematurely abstracting code can lead to complexity and maintenance issues. It illustrates this through an example involving a bonus calculation system for employees and contractors. Initially, the developer consolidates similar logic into a shared function, but as requirements change, new parameters are added over time, leading to a convoluted and unwieldy function. This scenario highlights the

The author expresses concern about the "fast-math" compiler flag, which is available in many programming languages and compilers (like GCC, Clang, ICC, MSVC, and Julia). While this flag enhances the speed of mathematical computations, it does so at the cost of accuracy and adherence to the IEEE 754 standard for floating-point operations. Fast-math allows compilers to perform optimizations that may violate these rules, leading to potentially significant and detrimental effects. In GCC, for example,

Joseph Izaguirre discusses the potential of using Ruby, paired with the Async library, for building a web crawler, despite it not being a typical choice for I/O heavy tasks. He acknowledges that languages like Go, JavaScript, and Elixir are generally more recognized for their event-driven, non-blocking architecture, but argues that Ruby offers superior readability and expressiveness. The article focuses on demonstrating how to integrate concurrency into a simple web crawler, highlighting that the provided code is for illustrative purposes and

Manifest V2 extensions in Chrome are currently disabled by default for all users, though they can be re-enabled temporarily. The rollout of a phase where users can no longer turn them back on has begun for some in the Canary channel. Enterprises using the ExtensionManifestV2Availability policy will remain exempt from these changes until at least June 2025. Starting in June 2025, with Chrome version 139, support for Manifest V2 will be completely removed, affecting all users simultaneously; Chrome 138

.NET 10 Preview 4 introduces a new feature that simplifies running C# code by allowing developers to execute a C# file directly with the command `dotnet run app.cs`, eliminating the need for a project file. This enhancement, called file-based apps, makes C# more accessible for beginners, enabling quick script testing and experimentation without the complexity of creating a full project structure. File-based apps support useful directives that allow users to declare aspects typically found in project files, such as adding NuGet

Japan Post has introduced a "digital address" system, linking seven-digit codes to physical addresses. This allows users to input the codes on online shopping sites for automatic address filling. Individuals can obtain these digital addresses by registering with Japan Post's Yu ID service, which remain unchanged even if physical addresses do. E-commerce companies, including Rakuten, are considering adopting this new system, which Japan Post plans to promote over the next decade.

The history of Compiler Explorer's URL storage began in 2012, when the entire compiler state was stored in the URL. This approach became unwieldy, leading to the integration of Google’s link shortener, goo.gl, in 2014 for simpler links. However, in 2016, Stack Overflow banned link shorteners due to misuse, which affected Compiler Explorer's links. To navigate this, they modified their links to appear as godbolt.org/g/abc123, which redirected through

Managing access control in Ruby applications can start off simply but quickly becomes complex as applications grow. Initially, basic boolean flags and role checks may seem sufficient, but they lead to a tangled web of if-else statements that complicate maintenance and scalability of permissions. An efficient authorization system is crucial since it underpins application security and influences user experience. Role-Based Access Control (RBAC) offers a systematic solution by managing access through role assignments rather than individual permissions. This method aligns well with Ruby's syntax and
