The User Isn't the Buyer: Cracking the B2B Sales Puzzle

2025-08-08

This article tackles the common B2B SaaS problem of the 'user isn't the buyer'. The author argues that identifying the true decision-maker is key, and it's not always the person holding the credit card. In smaller companies, developers often wield significant influence due to direct product usage and time constraints, driving their need for efficient tools. Larger companies, however, typically place decision-making power with CTOs or leadership, prioritizing security and outcomes. The author suggests empowering developers by providing them with data and tools to convincingly demonstrate the product's value to leadership, indirectly leading to sales conversion.

Probing Browser Limits with Infinite CSS Values

2025-08-08

The author experimented with setting element width and height to `calc(infinity * 1px)` in CSS to explore how different browser rendering engines handle infinite values. Chrome and Safari capped the value at approximately 33,554,400 pixels. However, Firefox Nightly exhibited unusual behavior; height was limited to the text line height, while width reached millions of pixels, yet the layout width was roughly half. Further tests with font size and line-height revealed similar discrepancies, with Firefox's rendering drastically different from other browsers. The author speculates on the reasons for these oddities and invites readers to provide explanations.

Building a Custom In-Memory Table Access Method for Postgres

2025-08-08

This post details the author's journey building a custom PostgreSQL table access method, effectively creating a simple in-memory storage engine. Starting with a debug build of PostgreSQL, the author incrementally implemented the various functions of the table access method API, culminating in a fully functional system capable of creating tables, inserting data, and querying results. The process involved overcoming numerous challenges, including debugging and understanding PostgreSQL internals, which were addressed through logging and iterative debugging. This serves as an excellent example of PostgreSQL extension development, providing valuable experience and guidance for other developers.

Running x86_64 Apps on an AArch64 Desktop: A FEX-Emu Experiment

2025-08-07

This post details an experiment running x86-64 applications on an Ampere Altra-based AArch64 desktop system using FEX-emu. While Steam and Factorio ran, performance was poor, scoring a measly 459 and 4110 on Geekbench 6's single and multi-core tests respectively. Optimizations to FEX-emu's configuration and replacing the x86_64 version of the Ninja build tool with an aarch64 version yielded some performance improvements. Ultimately, the author concludes that x86_64 emulation on this AArch64 system is limited in practicality, primarily useful for running older games.

Forget Monads: Embrace Natural Transformations

2025-08-07

This article challenges the overuse of Monads in functional programming. The author argues that the concept of Monads is overly abstract and proposes using the underlying natural transformations directly for programming. Using the Я language as an example, the article explains how to combine different Functors using natural transformations, comparing this approach to Monad Transformers. It ultimately advocates replacing Monads with more flexible, lower-level natural transformations for cleaner and more powerful program design.

1.5 Years of AI-Assisted Programming: Reflections and Lessons Learned

2025-08-07

This post shares the author's 1.5-year experience using AI for programming. AI excels at repetitive coding tasks, refactoring, and simple projects, but struggles with complex problems and new development, often introducing errors and inefficient abstractions. CLI interfaces prove more effective than IDEs due to increased developer control. AI aids in design and writing, but 'vibe coding' (relying solely on AI-generated code) is discouraged, leading to significant technical debt and security vulnerabilities. The author concludes that the primary beneficiaries of AI aren't developers, but managers and clients, facilitating improved communication and collaboration. The future of AI in programming is bright, but companies shouldn't use it as an excuse for layoffs.

Debouncing in Programming: Efficiently Handling User Input

2025-08-07

In programming, debouncing is a technique used to handle frequent events, such as continuous user input. It discards operations that occur too closely together within a specified time interval, consolidating them into a single invocation to prevent UI lag. For example, when a user types a search query, debouncing waits for a pause before executing the search, improving efficiency and user experience. Similar to throttling, but unlike throttling which limits the frequency of continuous operations, debouncing waits for a period of inactivity before acting.

Advanced Zig Unit Testing Debugging: Combining Print Debugging and the Debugger

2025-08-07

This article presents techniques to enhance Zig unit test debugging, combining print debugging and the debugger. The author first addresses the issue of verbose print debugging output by using `errdefer` to print only when a test fails, reducing clutter. Then, the `build.zig` script is leveraged to run the debugger during the build process, simplifying debugging of test binaries. Finally, conditional compilation, combined with the build option `-Ddebugger`, allows enabling debugger breakpoints only when needed, avoiding debugger interference during normal test runs. This approach significantly improves Zig unit test debugging efficiency.

Breaking the Sorting Barrier: A New Algorithm Speeds Up Shortest-Path Finding

2025-08-07

For decades, a classic problem in computer science—finding the shortest path from a specific starting point in a network to every other point—has been limited by a 'sorting barrier'. Recently, Ran Duan and his team at Tsinghua University have broken this barrier, devising a new algorithm that surpasses all sorting-based algorithms in speed. The algorithm cleverly uses clustering strategies and the Bellman-Ford algorithm, avoiding point-by-point sorting and achieving significant performance improvements, opening a new chapter in shortest-path problem research.

comptime.ts: Compile-Time Computation for TypeScript

2025-08-07

comptime.ts is a dead-simple TypeScript compiler designed for efficient compile-time evaluation of expressions marked with `comptime`. This allows for code optimization by shifting computations from runtime to compile time. It supports various use cases, including calculating constants, generating static content, and optimizing performance-critical code. Integration is straightforward via Vite, Bun, or the CLI, boosting developer productivity. However, comptime expressions must be JSON-serializable, and complex expressions may increase build times.

Beyond Dynamic Arrays: The Efficient and Stable Segment Array

2025-08-07

This article introduces Segment Array, a high-performance data structure combining the flexibility of dynamic arrays, the advantages of stable pointers, and excellent compatibility with arena allocators. Unlike dynamic arrays that move elements during resizing, Segment Array uses pre-allocated segments of fixed sizes, avoiding memory fragmentation and pointer invalidation. Each segment is double the size of its predecessor, with new segments allocated only when needed, achieving O(1) average time complexity. The author provides a C implementation and details its inner workings, including efficient index calculation and integration with generics. Segment Array is particularly useful in scenarios requiring efficient dynamic memory management within an arena allocator, such as in a build profiler.
