Functions as input, and modular monkeys.

The Functional Options Pattern is a safer alternative to struct literals, and is commonly used in Go. These are the challenges I encountered when trying it out in Rust.

Convert terminal output to tree structure of files and directories

Moving items between stacks.

Number interval intersections.

Set operations on the contents of Elf backpacks.

(Norwegian) I dag lærte jeg: Hvis du ønsker å tilgjengeliggjøre en server som kjører på en mobiltelefon, bak en 4G-ruter, eller på en PC med SIM-kort, og er på Telenor-nettverket (Telenor, Vipps Mobil, Fjordkraft, Gudbrandsdal Energi, Happybytes, NorgesEnergi), kan du gjøre følgende: I nettverksinnstillingene på dingsen din, finn “APN” (Access Point Name). Hos Telenor er denne f.eks. telenor.smart eller telenor.fwa. Endre denne til internet.public, og skru av/på flymodus eller restart dingsen din.

It’s happening! Finally December is here, and a new Advent of Code begins. I’ll try to write a very short post for each of my solutions.
