It is an important concept but it is not trivial to grasp. Often it is easier to understand new ideas by putting them into practice, in this blog entry we will see h... 6 min read · [lrodero.hashnode.dev](https://lrodero.hashnode.dev/understanding-kleisli-using-it-to-pass-context-info?utm_source=hashnode&utm_medium=feed) [Luis Rodero-Merino](https://hashnode.com/@gondolindrim) · [Aug 15, 2024](https://hashnode.com/posts/convert-future-instances-to-cats-effect-io/66be4fb0a62fd73901b56652) ### [Convert Future instances to cats-effect IO](https://lrodero.hashnode.dev/convert-future-instances-to-cats-effect-io?utm_source=hashnode&utm_medium=feed) Much (most?) of the third-parties software that you will have to deal with will not handle asynchronous actions using our beloved IO monad, they will instead use either Scala’s or Java’s Future. This brief entry shows how to convert those Futures int... 2 min read · [lrodero.hashnode.dev](https://lrodero.hashnode.dev/convert-future-instances-to-cats-effect-io?utm_source=hashnode&utm_medium=feed) [Luis Rodero-Merino](https://hashnode.com/@gondolindrim) · [Jun 2, 2024](https://hashnode.com/posts/micro-library-for-retries-in-cats-effect-using-scala-extensions/665c56da2c190aae648c4011) ### [Micro library for retries in cats-effect using Scala extensions](https://lrodero.hashnode.dev/micro-library-for-retries-in-cats-effect-using-scala-extensions?utm_source=hashnode&utm_medium=feed) This blog entry will show how to add a simple retry mechanism to cats-effect (CE) using Scala 3 extensions. The idea is that whenever we define our IO instances we can also specify that, if they fail and certain conditions are met, they will be autom... 6 min read · [lrodero.hashnode.dev](https://lrodero.hashnode.dev/micro-library-for-retries-in-cats-effect-using-scala-extensions?utm_source=hashnode&utm_medium=feed) [Luis Rodero-Merino](https://hashnode.com/@gondolindrim) · [Mar 24, 2024](https://hashnode.com/posts/dining-philosophers-problem-with-cats-effect/65ffffed83d0b6047c157d61) ### [The dining philosophers problem with Scala 3 and Cats Effect](https://lrodero.hashnode.dev/dining-philosophers-problem-with-cats-effect?utm_source=hashnode&utm_medium=feed) The dining philosophers problem is a classical concurrency problem.
