Subtle C++/WinRT Invoke Issue and its Fix

2025-03-09
Subtle C++/WinRT Invoke Issue and its Fix

A C++/WinRT pull request fixed an ambiguity in `winrt::impl::promise_base::set_completed`'s call to `invoke`, caused by Argument-dependent Lookup (ADL). The upgrade to C++20 coroutines expanded the ADL search space, unexpectedly finding `std::invoke` instead of the intended `winrt::impl::invoke`. The article details the ADL mechanism and provides a patch for older C++/WinRT versions: declaring a better-matching `invoke` function in the `winrt::Windows::Foundation` namespace to guide the compiler. This patch also includes a static assertion to ensure it's automatically removed after upgrading C++/WinRT.

Fintech Startup Slashes Data Infrastructure Costs by 70%

2025-03-09

A fintech startup tackled the challenge of managing diverse data sources and high infrastructure costs. Their initial platform, relying on Hevo and BigQuery, proved unsustainable. To overcome this, they built a new ELT-based data platform leveraging cost-effective S3 storage for raw data. They utilized Airflow, Debezium, Kafka, and dbt for data processing and transformation, Trino for querying, and Metabase for visualization. The result? A 70% reduction in infrastructure costs. This case study highlights how efficient data platform design and technology choices can drastically reduce expenses and improve efficiency.

Exploiting Constraints for Significant Performance Gains: Optimizing Even Number Counting in C++

2025-03-09

This article explores optimizing the performance of counting even numbers in a uint8_t array in C++. By comparing two approaches—using `std::count_if` and a custom counting function—the author demonstrates that the custom function, leveraging the constraint that the number of even values is between 0 and 255, significantly improves performance, achieving up to a 9.5x speedup in tests. The article analyzes the assembly code generated by both methods, explaining the performance difference, and mentions a vectorization issue in specific GCC versions.

Go's Error Handling: A Blessing or a Curse?

2025-03-09

Go's error handling, characterized by the ubiquitous `if err != nil` check, has sparked considerable debate. Critics find it verbose and cumbersome, while proponents argue it's a cornerstone of Go's philosophy, treating errors as first-class citizens. This article delves into the pros and cons, comparing Go's approach to exception handling in languages like JavaScript. It highlights best practices, such as creating actionable error chains using `fmt.Errorf` and leveraging libraries like `github.com/pkg/errors` for enhanced clarity and stack traces. While not without flaws, Go's explicit error handling empowers developers with full control over program flow, emphasizing simplicity and proactive failure planning.

Compiler Optimization: Improving Lemire's Nearly Divisionless Random Number Generation

2025-03-09

The author improved a nearly divisionless algorithm for generating bounded random numbers (Lemire's algorithm). A previous version reduced code bloat by inlining the fast path, but compiler optimization was limited. The author discovered that when the limit is a compile-time constant, the rejection threshold can be precomputed, and division avoidance is unnecessary. The new implementation has only one call to the random number generator, and the compiler automatically eliminates the loop when the limit is a power of two. This is more efficient than last year's version, and the author explores similar compile-time optimization techniques in Rust.

The LFortran compiler team successfully compiled and executed libprima/PRIMA, marking the eighth production-grade, third-party code compiled with bit-for-bit alignment to GFortran. This significant milestone brings LFortran closer to its goal of compiling ten such codes, a key step toward achieving beta-quality. Compiling PRIMA, a Fortran package for nonlinear optimization, presented challenges related to procedure variables, arrays with non-unit strides, and precision loss, all of which were overcome. Future efforts focus on compiling additional third-party codes, including fpm and LAPACK, to solidify LFortran's beta readiness.

Next.js Pre-rendering: How Much Traffic Can It Really Handle?

The author tested the traffic capacity of their Next.js pre-rendered site and found a VPS server could only handle around 200 concurrent requests, far lower than expected. This led to an upgrade to a dedicated server, resulting in a significant performance improvement, handling thousands of requests per second. In contrast, server-side rendering (SSR) performed significantly worse than pre-rendering, struggling under high traffic. The article also discusses the pros and cons of other solutions like Cloudflare and Vercel, ultimately opting for a dedicated server for scalability. Future tests will explore further optimizations.

Ditch the Top-Down Approach: Why Bottom-Up Code Auditing is More Efficient

2025-03-09

Security consultants often need to become experts in a codebase quickly without writing code. This article critiques the inefficient top-down approach to code auditing, likening it to trying to visualize a whole marathon from the air – discouraging and overwhelming. The author advocates a bottom-up approach: deeply understanding code details, gradually expanding scope, ultimately gaining a deeper understanding than even some developers, and finding more bugs. This method is not only more efficient but also more enjoyable.

FSF Weighs In on Neo4j's AGPLv3 License Dispute

2025-03-09

The Free Software Foundation (FSF) filed an amicus brief in the legal dispute between Neo4j, Inc. and PureThink, LLC. The core issue revolves around Neo4j adding a commercially restrictive Commons Clause to its software, incompatible with the GNU AGPLv3 license. The FSF argues that GNU licenses permit users to remove restrictions contradicting the four freedoms of software. Following a cease and desist letter in November 2023 highlighting Neo4j's violation of the AGPLv3 spirit, Neo4j removed the offending files and ceased offering its software under the GNU AGPLv3, implicitly acknowledging the FSF's position. The FSF's brief clarifies its intent in drafting the GNU licenses and underscores its commitment to safeguarding software freedom.
