A new study by researchers at the University of California, Riverside, reveals that replanting forests could reduce global temperatures by about 0.34 degrees Celsius, which represents roughly one-quarter of the warming caused by human activities to date. This research emphasizes the potential to restore around 12 million square kilometers of tree area, corresponding to estimates of planting 1 trillion trees, as the planet has lost nearly half its trees since industrialization. However, lead author Bob Allen cautions that reforestation is

This page summarizes recent changes to the Zig programming language's main branch, specifically focusing on updates from 2025. One significant change is that Zig will now use its own x86 backend by default for x86_64 targets, improving compilation speed dramatically—from 75 seconds to 20 seconds for larger projects like the Zig compiler—while also achieving better performance in behavior tests compared to the previous LLVM backend. The default setting for Windows hasn't changed yet due to pending COFF linker work. Future improvements are

Automated formal verification tools like Dafny and Viper are gaining traction in industries such as AWS and Microsoft for verifying safety-critical software. However, as these tools are applied to larger codebases, issues like slow and brittle proofs are becoming apparent. Proof brittleness occurs when verification times become inconsistent, and minor changes in the code can unexpectedly lead to failed verifications, often due to dependencies on irrelevant program features within the SMT solver. This has prompted developers to invest significant effort in mitigating these issues, but
