Local CPU tasks. Remote work over the network. GPU kernels.

These are very different kinds of operations — but HPX lets developers coordinate them through a uniform asynchronous execution engine.

That consistency can make complicated parallel applications much easier to build and optimize.

C++ code can look perfectly reasonable and still hide a dangerous bug. ⚠️

When you pass a reference to an element of a std::vector and then call push_back(), a reallocation can invalidate that reference. Suddenly, what looked safe becomes undefined behavior.

Watch the short to see how a simple function can create a dangling reference.

What does an impossible chessboard puzzle have to do with C++?

More than you might think. ♟️

This short from Joaquín M. López's Using std::cpp 2026 talk shows how mathematical models and invariants can provide powerful ways to reason about problems.

Imagine an oven with heating elements at the top and bottom. Now simulate how that heat spreads through the entire space.

🌡️ Grid discretization
🔥 Heat equation
🔄 Double buffering
⚡ Parallel computation
Bernhard Manfred Gruber shows how these ideas come together in a CUDA C++ implementation.

Boost has played a major role in the evolution of modern C++.

Many facilities that were once provided through Boost eventually became part of the C++ standard library, while other Boost libraries continue to provide useful functionality beyond the standard.

It's a fascinating example of how libraries can influence the language itself.

std::regex_match(line, std::regex(“.*”))

On GCC’s libstdc++ that segfaults on a 30,000 character line. The matcher recurses for every character it consumes until the 8 MB default stack runs out. No exception, no error message 🧵👇

Boost Blueprint 139: Boost.Regex

Nix has a PR open moving Determinate Nix’s flake reference parsing from std::regex to boost::regex. The trigger: a crash report where nix path-info "$(cat paths)" blew the stack on one long argument. Lix, the Nix fork, already made this switch in 2024 for the same reason

Boost.Regex keeps its backtracking state on the heap, not the call stack. The same .* matches a 10 MB line, and a pattern with catastrophic backtracking throws an exception you can catch instead of taking the process down

PCRE was tried too and turned down. Boost.Regex stays closer to std::regex behavior, so existing patterns keep working

Boost.Regex also brings named captures and recursive patterns, which std::regex lacks

Why is memory safety so challenging in C++?

One major reason is aliasing: multiple pointers or references can refer to the same object, making it harder to reason about ownership and lifetime.

And sometimes, the code that creates the problem looks completely harmless.

What should your system do when its queues fill up?

Not every message has equal importance. In financial systems, cancel orders must take priority, while lower-priority analytics requests may need to be dropped.

Resilience means knowing what to protect when you can't do everything.

A thread that outlives its process can turn shutdown into a crash waiting to happen. 💥

If a thread accesses an object after its lifetime has ended, even a carefully written application can fail catastrophically.

Concurrency design must account for the entire lifecycle: startup, execution, and shutdown.

Overload isn't an edge case. It's inevitable. ⚠️

In financial systems, market activity comes in bursts. When more work arrives than your system can handle, what happens next matters enormously.

The answer isn't to hope your infrastructure holds up. It's to define how the system should behave under pressure — before it happens.

std::variant<int, Config> v = Config(...);

If an emplace throws halfway, v holds neither an int nor a Config. valueless_by_exception() is a state you never put in the type, and std::visit throws bad_variant_access on it 🧵👇

Boost Blueprint 138: Boost.Variant2

boost::variant2::variant is never valueless. Assignment and emplace provide the strong exception guarantee: if constructing the replacement throws, the original value remains intact

When all alternatives are nothrow move constructible, it uses single storage. Otherwise, it uses double storage to preserve the old value until the new one is ready. No heap allocation, no surprise empty state, no unexpected exceptions when visiting a valueless variant

Same interface as std::variant, from C++11

How you handle GitHub issues says a lot about your open-source community.

The goal isn't just closing tickets—it's creating a workflow where useful bug reports, feature requests, questions, and community feedback can all find the right place.

CUDA C++ is an extension of standard C++ designed to express programs that can execute on the GPU.

The interesting part? Your application still has a CPU side, with standard C++ code, alongside GPU execution.

It's a bridge between two very different processor architectures.

C++20 added jthread, stop_token, latch, barrier and counting_semaphore

Still no thread-safe queue. The proposal dates to January 2012 and now targets C++29, so every codebase has a mutex, a std::queue and a condition_variable somebody wrote at 2am 🧵👇

[Boost C++ | Open Source Libraries @Boost_Libraries]

Boost Blueprint 137: Boost.Lockfree

boost::lockfree::queue is a multi-producer, multi-consumer queue built on atomic compare-and-swap. When the capacity is fixed, there is no mutex, so a thread that gets preempted can’t stall every other producer and consumer

spsc_queue is wait-free for the one producer, one consumer case, and stack gives you a lock-free LIFO

The trade: queue’s elements need a trivial destructor and assignment, and pop returns immediately when empty. For blocking handoff between fibers, Boost.Fiber’s buffered_channel supports ordinary value types
