Parsing IPv6 Addresses Crazily Fast with AVX-512Every machine connected to the Internet has an address called an IP address. Originally, these addresses were 32-bit integers (IPv4), giving a theoretical maximum of about four billion distinct addresses. We are all familiar with these addresses (e.g., 192.168.0.0). There was a big fuss about how we would run out of addresses. It never happened … Continue reading Parsing IPv6 Addresses Crazily Fast with AVX-512📝Daniel Lemire's blog

Does bulk memmove speed up `std::remove_if`? (No.)This morning I was reading the umpteenth std-proposals thread proposing some variety of unstable_remove and it occurred to me that one odd thing about a swap-and-pop-based unstable_remove is that it tends to replace large swaths of contiguous removals by reversing the elements that are kept. For example (Godbolt):📝Arthur O’DwyerFriday, May 22, 2026

Only 17% of all 64-bit Integers are products of two 32-bit integersIn software programming, the product between two integers is often computed to a fixed number of bits with overflow. Consider 8-bit integers. If you multiply 127 by 127, you get back the number 1 as an 8-bit unsigned integer, with an overflow. The actual full product is 16129. To represent 16129, you typically use 16 … Continue reading Only 17% of all 64-bit Integers are products of two 32-bit integers📝Daniel Lemire's blogThe _Book of St Albans_ (1486)This week I read James Lipton’s An Exaltation of Larks; or, The Venereal Game (2nd edition, 1977), a discursive collection and celebration of “terms of venery” — the collective nouns like “school of fish” and “pride of lions” that were (so the story goes) mostly invented by medieval hunters who wanted to have their own proper jargon to distinguish the real hunters from the dilettantes.📝Arthur O’DwyerThursday, May 21, 2026

Qt for MCUs vs LVGL: A Comparative Study from Design to DeploymentWhen comparing Qt for MCUs vs LVGL, an independent study by Spyrosoft (updated with new data in May 2026) shows that Qt for MCUs reduces development time by approximately 30% compared to LVGL , requires roughly half the handwritten application code, and achieves better or equivalent FPS performance at a fraction of the CPU usage. The efficiency improvement comes mainly from Qt's integrated toolchain, which facilitates better collaboration among designers, developers, and QA engineers. Additionally, Qt for MCUs offers comprehensive safety certification, professional services, and support, positioning it as a superior LVGL alternative for complex projects where functional safety and compliance are essential. A second benchmark released by Silicon Signals confirms the performance advantage in both CPU and RAM consumption.📝Qt Blog

A Cross-Platform C# UI Framework via Qt’s Bridging TechnologyEvery C# UI framework comes with a familiar pattern: Windows-first, Linux absent, roadmap uncertain. WPF stalled, MAUI skipped Linux, WinUI 3 stays Windows-native. At the same time, demand for embedded Linux grows and C# teams feel the lack of good UI alternatives for C# on Linux. Qt Bridges, a bridging technology in public beta for C#, provides access to a UI framework that allows preserving your existing C# codebase while utilizing Qt Quick’s feature-rich UI libraries and APIs, hardware acceleration, and cross-platform capability.📝Qt Blog
Qt Bridges: Public Beta for the C# Bridge Is Out!Qt Bridges is a project we have been developing since 2025 to bring Qt’s UI framework capabilities to other programming languages, without going through the full set of bindings. The focus is on the interaction with backend data objects, seamlessly integrated as QML components in a Qt Quick interface.📝Qt Blog
