#hashmaps — Public Fediverse posts

Ah yes, the riveting world of #C++ hashmaps—where time stands still and somehow still takes forever. 😴🔄 After 3 years, Martin bravely ventures back to prove that the art of #benchmarking is the best way to waste your time while pretending to be productive. ⚙️📉

Mutable Schlüssel in #HashMaps können zu unsichtbaren Einträgen führen. Warum hashCode()-Änderungen fatale Folgen für Lookup, Security & Konsistenz haben, zeigt @svenruppert in der interaktiven #Vaadin-Demo. Teste es: https://javapro.io/de/wenn-hashcode-luegt-und-equals-hilflos-ist/

#rust day. Onto #vectors, #strings, #hashmaps. Definitely encrypted strings are an area I had hard times in other languages, so this should be a good read.

Starting #problemsolving on #leetcode (leetcode.com) using #rustlang | #rust. First a simple #problem for retrieving indices of a vector where two elements match a target sum. Learning some basic Rust along the way even with this brute force solution. Apparently it's the most memory efficient among the submissions, although it's quite slow. Something faster could be achieved with #hashmaps or the like.
