The C++26 inplace_vector containerThe C++26 standard features a new container called std::inplace_vector, that sits in between the std::array and std::vector containers. It’s a container with a compiled-time fix capacity – like std::array, but a runtime variable size – like std::vector. In this article, we will discuss how it works and when to use it.

Bazel releases addressing the eMudhra CA compromiseThe Bazel team has published new releases of Bazel and Bazelisk to address the recent disclosure of the eMudhra intermediate CA private key compromise . The following Bazel releases remove the distrusted eMudhra and Sectigo AAA root CA certificates from the bundled JDK: 7.7.2 8.8.2 9.3.1 10.0.0rc2 If you cannot immediately upgrade to one of the patched releases above (or are using an older, unsupported Bazel release), you can work around the issue by passing --host_jvm_args=-Djavax.net.ssl.trustStore= to point Bazel's JVM at an updated trust store that excludes the distrusted roots. We have also released Bazelisk v1.30.0 , built with Go 1.27.3 to address CVE-2026-111943 . Thanks to community member James Sharpe for bringing this issue to our attention.Bazel BlogThursday, October 22, 2026

C++26 Ranges: Better InfrastructureC++26 ranges isn’t only about new view adaptors. Three changes landed that don’t give you new ways to compose pipelines but fix real problems: containers can now reserve space for lazy ranges that don’t know their exact size, finally works with ranges, and ranges::to no longer forces you into a | pipeline when a simple function call would do. approximately_sized_range and rese...Sandor Dargo's Blog
AMR Contour and Interface support in VTK and ParaViewAdaptive Mesh Refinement (AMR) is a popular method of numerical simulation used to adapt the accuracy of the simulation, which produces volumes of data of different levels of detail. While this can be achieved using an unstructured grid, using a dedicated data model is preferred as it improves computation speed and memory usage.Kitware IncMicrospeak: Drain the slide, back-up slidesPowerPoint presentation jargon.
