Bringing Safety to HEPBringing Safety to HEP High-Energy Physics software is routinely trusted with complex detector geometries spanning millions of volumes, critical tracking and reconstruction algorithms, and multi-day simulations running on the Grid. A single silent unit mismatch in a double can invalidate an entire analysis or produce detector geometry that is 10Γ the wrong size. This post shows how mp-units can bring compile-time safety to HEP codebases (including a dedicated HEP system of quantities and units) and how large projects like ATLAS can adopt it incrementally without requiring a big-bang rewrite.πmp-unitsIf this page is useful, please consider donating a coffee

Propagating exceptions from destructors with std::exception_ptrA few weeks ago, I wrote about what happens when a destructor actually throws and why it is a dangerous idea. One of the readers commented that he was once in a situation where he had to propagate an exception from a destructor. But as a destructor cannot safely throw and it also cannot return any value, he needed a better solution. And that solution was std::exception_ptr. Letβs look into wh...πSandor Dargo's Blog

Product Updates Upcoming Bazel releases Bazel 9.2.0 is expected to release on 2026-07-09. RC1 was released on 2026-06-25. Bazel 8.8.0 is expected to release on 2026-07-15. Please send cherry-pick PRs against the release-8.8.0 branch before the RC1 cutoff on 2026-07-08. Q2 releases 9.1.0 was released in April β26, followed by patch 9.1.1 . 8.7.0 was released in May β26. Community Corner Updates from the JetBrains* team: Bazel for CLion plugin updates Debug flags are no longer injected automatically by debug run configurations. If your build already includes debug symbols, this change shouldn't impact you; otherwise, check the details here: https://jb.gg/clwb-debug-docs . You can now switch configurations if the current source file is built under multiple configurations in your project. Additionally, when you start debugging, we'll automatically select the correct configuration to keep your code insight and debug session in sync. Developments in the Bazel plugin by JetBrains for IntelliJ IDEA, PyCharm and GoLand in 2026.1 Improved stability and less freezes: all known freezes caused by the Bazel plugin have been fixed. Sync performance improved, with overhead removed. Less spurious analysis cache invalidations. Better hot swap in JVM applications. Graceful cancellation for Bazel run and build. Bazel 9 compatibility. More readable build and sync progress in IDE output. Find more details on the plugin "What's New" page. In the upcoming 2026.2 version, the team is focusing on improved support for Bazel projects with Python and Go, in particular when opened in PyCharm and GoLand.

Break MSVC and Clang with this one weird trick!A few weeks ago I came across some code that MSVC and Clang both rejected, but GCC accepted. The error messages are different in MSVC and Clang, so clearly I must have done something wrong, and GCC falsely accepts the code, right? I mostly minimized the code, and ended up with this. (Compiler Explorer link) struct S{}; template void foo(T) { (void)[] (U) consteval -> bool { return requires { 0 * T{}; }; }(0); } void bar() { foo(S{}); } In this post I will explain how I got here, what I think is going on with all 3 of these compilers, and allude to what Iβll be talking about in the next article after this one.πBraden++Saturday, July 4, 2026
