Modern C++ codebases — from browsers to GPU frameworks — rely heavily on templates, and that often means massive abstract syntax trees. Even small inefficiencies in Clang’s AST representation can add up to noticeable compile-time overhead. This post walks through a set of structural improvements I recently made to Clang’s AST that make type representation smaller, simpler, and faster to create — leading to measurable build-time gains in real-world projects. A couple of months ago, I lande...

Back in April my former colleague Christian Mazakas has announced his work on registry of nightly Boost packages for vcpkg. That same month Conan developers have introduced a new feature that significantly simplified providing of an alternative Conan package source. These two events gave me an idea to create an index of nightly Boost packages for Conan. Conan Remotes Conan installs packages from a remote, which is usually a web server. When you request a package in a particular version rang...

In a past life I worked in the computer journalism business, and learnt over time what attracts people to read a page. Lot’s of things are important, the font used, the spacing between letters and lines and paragraphs, even the width of a column of text is super-important for readability (so the eye does not lose track of the line it is on). Other stuff is important to, readers, especially technical readers, love tables. A table of all the networking libraries available in Boost for example, ...

Over the past three months, I’ve been immersed in a deep and wide-ranging overhaul of the Boost.DynamicBitset library. What started as a few targeted improvements quickly evolved into a full-scale modernization effort—touching everything from the underlying container to iterator concepts, from test coverage to documentation style. More than 170 commits later, the library is leaner, more flexible, and better aligned with modern C++ practices. Making the core more flexible The most transforma...

During Q3 2025, I’ve been working in the following areas: Boost.Bloom Boost.Bloom has been officially released in Boost 1.89. I’ve continued working on a number of roadmap features: Originally, some subfilters (block, fast_multiblock32 and fast_multiblock64) implemented lookup in a branchful or early-exit way: as soon as a bit checks to zero, lookup terminates (with result false). After extensive benchmarks, I’ve changed these subfilters to branchless execution for somewhat better perfo...
