What Does "ArgumentNullException" Mean? In layman's terms, an ArgumentNullException occurs when a method expects you to give it something (an argument), but you give it nothing (null).

If you show up without any food, it's like you brought "nothing" to the table. The host might be frustrated because the event relies on everyone contributing. Similarly, when a method expects an argument and you pass…

DEV Search: 20x Latency Reduction By Layering Algolia On Top of Postgres

stp2y0 CommentsNewsalgolia, coding, community, development, engineering, inclusive, meta, software, webdev, webperf

At DEV, our commitment to open-source development drives our decision-making process, especially regarding the tools and technologies we use. Our platform, which we open source as Forem, reflects this ethos. Forem is an open-source Rails application designed to foster community and content sharing. As a backstop for this approach, the base search is implemented in Postgres to serve small and straightforward use cases. However, to serve a high-traffic global network, it is not an entirely sufficient experience. Latency is the only objective measure of user experience. If a request loads slower, users are going to leave and/or lose trust in…
