A Decade-Old Fileserver's Second Life: Cost-Effective Storage Solution

2024-12-17

A company is still running a production machine, a fileserver over a decade old. While outdated, with a BMC requiring Java for KVM-over-IP, its 16 disk bays and 10G Ethernet ports make it ideal for repurposing. Used as a bring-your-own-disk low-cost storage server, it fulfills the need for high-capacity, low-performance storage despite its age and limited RAM. This highlights the value of reusing old hardware when requirements align.

Rust's Vec::drain: Leveraging Drop for Safety

2024-12-16

This article delves into Rust's Vec::drain method and its Drop implementation, showcasing how ownership prevents subtle bugs—memory-related and otherwise. Vec::drain optimizes performance by maintaining a mutable reference to the original vector and only reading/updating the original storage. The key lies in the Drain struct's Drop implementation, which uses a DropGuard to ensure that even if the iterator is dropped prematurely, remaining elements are safely moved back into the original vector, guaranteeing memory safety. The article thoroughly explains the implementation details of Drain and DropGuard, addressing special cases like zero-sized types and pointer provenance.

MacOS GPU Optimization: Wasting Resources for Speed

2024-12-15

Anukari's developer encountered a bottleneck while optimizing GPU performance on MacOS. Due to limited system control over GPU performance, Apple's GPU performance regulation mechanism performed poorly in Anukari's use case, resulting in audio glitches. The developer implemented a workaround: dedicating a GPU threadgroup warp to useless computation to 'trick' the system into increasing GPU clock speed, significantly reducing audio latency and improving performance. While crude, this method proved effective in resolving MacOS performance issues. However, performance improvements varied significantly between different DAWs (Ableton and GarageBand), requiring further optimization.

Scientists Discover Four New Species of Portuguese Man-of-War

2024-12-14

Recent research has uncovered four new species of the Portuguese man-of-war, challenging our understanding of this venomous creature. Far from being a single organism, the man-of-war is a colony of four or five distinct individuals, each responsible for functions like floating, stinging, digestion, and reproduction. This unique colonial structure is a marvel of natural engineering. Adding to its intrigue, the man-of-war inflates its float using carbon monoxide and reproduces via a mysterious process with poorly understood larval development. Furthermore, a parasitic fish, the bluebottle, feeds on the man-of-war's tentacles and gonads, further highlighting the species' complexity.
