Fastest Branchless Binary Search
Summary: A new branchless binary search C++ implementation, called sb_lower_bound, claims to be 2x faster and shorter than std::lower_bound. The "branchless" aspect refers to the use of a conditional move instruction instead of a branch/conditional jump, resulting in fewer instructions in the loop and improved performance. The article explores compiler options, faster versions, and caveats, with the code available on GitHub.

Dreams of new physics fade with latest muon magnetism result
Summary: The Muon g-2 experiment at Fermilab has doubled the precision of its previous measurement of the muon's magnetic moment, confirming earlier findings. While the muon's odd behavior was once seen as a possible sign of new physics, recent results suggest that the theory might not need major amendments.
