ÜBER DIESE EPISODE
Each week, we discuss a different topic about Clojure and functional programming.
If you have a question or topic you'd like us to discuss, tweet @clojuredesign, send an email to feedback@clojuredesign.club, or join the #clojuredesign-podcast channel on the Clojurians Slack.
This week, the topic is: "trying again". We throw our code in a loop, and it throws us for a loop.
Our discussion includes:- Sportify continues!
- When is it time to stop developing?
- How do we handle retries?
- What if you need to
recurfromcatch? - How do we recover mid-process?
- Where should the recovery logic go?
- Is there a way to get all the critical context at the same level?
- What should you preserve across a
recur? - What does it mean to be "loop native"?
- What is the basic structure for any automation?
- What is a "single application state"?
-
It's a lot like having a project on a workbench. You have all of the tools and all the information laid out before you on that workbench. Nothing is tucked in a drawer or inside a cabinet.
-
That's a very important lesson for any developer: you can always stop—at least after it's working.
-
Nothing in the world is solved except by adding another level of abstraction.
-
I was not expecting that level of mutation! I was expecting a Kafka log written in stone!
-
The positive is it has everything. The negative is it has everything.
-
We would like more loop-native code inside of our cloud-native application.
-
Are you suggesting that just because we can, it doesn't mean we should? We're programmers! If the language lets us do it, it must be a good idea!
-
One of the reasons why I like Clojure is because it specifically tells me that I can't do some things that are bad to do.
-
All of the context is in one map. It has everything in it. One map to rule them all!
-
Might this be the fabled "single application state"?
-
We have the thinking function, the doing function, and the assimilate function.
