console.log("Apple");
console.log("Banana");
console.log("Cookie");

You can nest groups inside of one another. To end a group just call console.groupEnd()

The Unreasonable Effectiveness of SKIP LOCKED in PostgreSQL

Using SKIP LOCKED to distribute work across machines in a distributed system is a popular pattern. We explore why, the alternatives, and a real world example from our own codebase.
Nadeesha Cabral on 17-12-2024

When building distributed systems that need to process jobs or tasks concurrently, one of the most challenging problems is ensuring that work is distributed efficiently without duplication. PostgreSQL's SELECT FOR UPDATE SKIP LOCKED feature provides an elegant and performant solution to this problem that almost feels too good to be true. We're big believers in the just use postgres ethos, as our source code might tell you.

ripgrep (rg)
ripgrep is a line-oriented search tool that recursively searches the current directory for a regex pattern. By default, ripgrep will respect gitignore rules and automatically skip hidden files/directories and binary files. (To disable all automatic filtering by default, use rg -uuu.) ripgrep has first class support on Windows, macOS and Linux, with binary downloads available for every release. ripgrep is similar to other popular search tools like The Silver Searcher, ack and grep.
