The Mojo🔥 language is now fully open source under the Apache 2.0 license (with LLVM exceptions)! The source code for the Mojo compiler, tooling, and everything else you need to build the language are now available in modular GitHub repository.

The Mojo language is a bold bet: a novel general purpose programming language that goes further than older ones. Mojo integrates the latest in compiler and programming language research to unlock GPUs, AI accelerators, and other advanced compute. For the last four years, Mojo has been developed with an open community, but a closed compiler. Mojo hit 1.0 (with source stability), and today its entire compiler and toolchain has been open sourced!

According to the TIOBE Index (August 2026), Python remains the #1 programming language worldwide, holding a commanding 18.5 % share — ahead of C (11.1 %) and C++ (8.6 %). SQL, R, and Rust round out the top 10, showing Python’s continued dominance across data and automation fields.

The ISO C++ Committee has finalized the core technical features for the upcoming C++26 standard while simultaneously voting on the first major working drafts for C++29. A massive highlight of C++26 is the long-awaited inclusion of compile-time reflection, which allows code to inspect its own structure natively and eliminates slow template metaprogramming tricks. The update also introduces formal Contracts (pre and post keywords) to guarantee code conditions, the std::execution framework for advanced asynchronous tasks, and native std::simd support for faster mathematical processing. Major open-source compilers like GCC and Clang have already implemented many of these features ahead of the official standard release, while the modern LLVM 22 infrastructure has updated its backend to support next-generation processor architectures.

Concurrently, the committee is facing intense industry and government pressure to address long-standing vulnerabilities, driving a massive push for memory safety in the C++29 draft. To combat the migration of critical infrastructure to memory-safe languages like Rust, the committee has introduced an official Undefined Behavior (UB) Catalog annex to systematically track and eliminate code vulnerabilities. Furthermore, creator Bjarne Stroustrup is spearheading "Safety Profiles"—a set of compiler-enforced rules designed to prevent severe bugs like buffer overflows and null-pointer dereferences without sacrificing raw execution speed. Supported by organizations like the C++ Alliance, the ecosystem is rapidly evolving to deliver robust, high-performance tools capable of meeting modern security standards.
