Why the CrowdStrike bug hit banks hard
A misconfiguration in CrowdStrike Falcon\'s endpoint monitoring software led to widespread system failures in banks, resulting in operational disruptions and cash withdrawal issues for customers. This incident exposed vulnerabilities in financial institutions\' reliance on security tools that operate in kernelspace, which can have extensive and unintended consequences. Despite the turmoil, most banks returned to normal operations shortly thereafter, highlighting the fragility of modern financial infrastructure.
How Great Was the “Great Oxidation Event”?
The Great Oxidation Event (GOE), occurring around 2.4 billion years ago, marked the first significant accumulation of atmospheric oxygen, but there\'s ongoing debate about the actual levels and their sufficiency for early animal life. Recent research from the Rio Tinto in Spain suggests that previous estimates of low oxygen levels may be misinterpreted due to the effects of acidic conditions on chromium isotope fractionation, indicating that oxygen may have been present in adequate amounts for animal evolution much earlier. This re-evaluation raises questions about why, despite sufficient oxygen, early animals didn\'t appear until the late Proterozoic, potentially due to fluctuating ocean oxygen levels and nutrient scarcity.
Divers Discover Mesmerizing Roman Mosaic Beneath the Sea
Divers have discovered a stunning ancient Roman mosaic beneath the sea near Naples, Italy, believed to date back to the third century C.E. The mosaic was part of a luxurious villa located in Baiae, a town known for its hedonistic reputation during the late Roman Empire. Restoration efforts are underway to preserve the fragile design, with researchers also recovering fragments of the villa\'s walls that once reached up to 32 feet tall.
Crafting Interpreters with Rust: On Garbage Collection
Tung Le Vo explores implementing a garbage collector (GC) for a Lox interpreter written in Rust, initially struggling with memory leaks due to reference counting before deciding to implement a mark-and-sweep GC. The post discusses the differences in memory management semantics between Rust and Lox, highlighting the need for mechanisms to enable shared mutable access and pointer aliasing while addressing these discrepancies. Ultimately, Vo emphasizes that, while Rust\'s safety guarantees complicate building a GC, it is still feasible to implement one, showcasing various methods and encouraging exploration of Rust\'s type system for safe memory management.
