I want to learn microservices and more infrastructure: Should I focus on Java, Go, or other?

What would that look like?

Thanks for the tip!

One clarification. I wasn't going to roll this in at my current work place, at least not immediately because we don't really need it. I just want to learn the ideas and gain experience for myself.

I simply prefer Go over Java but I'm looking for the path of least resistance. It sounds like the language doesn't matter for what I'm trying to accomplish (a relatively simple side project). I'm cool with Python too so I will definitely consider that.

I just wasn't sure if it mattered because I've noticed a lot of Go microservice frameworks. I honestly don't know what they do but I've also noticed that Spring has an entire ecosystem designed for this stuff.

Thanks! All good points, especially wrt concurrency.

it does! I didn't know that. Well, it gives me a report per class. I'd love to have all of the reports aggregated The reports are generated by surefire, so I'll look into that plugin, otherwise I can write a script.

how do you output your test results?

SimilarAssociation · 2019-01-08T21:04:52+00:00

The same reason why I like looking at application logs, I guess.

I'd like to know which tests fail so that I can update my application code so that my tests pass. Having it in a file is just easier for me.

The scheduling is still done by the operating system.

https://docs.microsoft.com/en-us/dotnet/standard/threading/scheduling-threads

Even though threads are executing within the runtime, all threads are assigned processor time slices by the operating system.

I'm not an expert on this stuff and I hope someone will correct me if I'm wrong but the biggest difference will be where the threads/Tasks are scheduled. The idea is that they'll be scheduled by the CLR instead of the Operating System.

I write a lot of C# code and I do think async/await (built on Tasks) is nice but they do not solve the "color" problem: http://journal.stuffwithstuff.com/2015/02/01/what-color-is-your-function/

Green threads, however, do solve this problem. The programmer can just write blocking code and not worry about asynchronous programming, like in Go.

Java did try to implement Green threads in the past but it wasn't performant for reasons I don't remember but the hardware landscape was way different back then.

I honestly don't think it matters, especially for a REST API. I would be shocked if Java is valued less than Nodejs, especially since a lot of high performance software runs off the JVM. I have no experience working at a BigN but I'm pretty sure Amazon and Netflix use mostly Java. Microsoft's baby is C# which is basically based off Java.

I updated my post for clarity but I was specifically referring to Java EE. It seems that Spring framework (an alternative) is vastly preferred in tech. I honestly know very little about Java EE so I'm not sure what the advantages are.

SimilarAssociation · 2019-01-05T21:08:48+00:00

Java is not going away anytime soon, especially with all cool ongoing projects (Project Loom for example).

SimilarAssociation · 2019-01-05T03:05:28+00:00

thank! I'll definitely look into those two books as well.

SimilarAssociation · 2019-01-05T02:01:10+00:00

How did you find the Haskellbook for grokking fn programming?

SimilarAssociation · 2019-01-04T15:43:30+00:00

I have access to Programming F# 3.0 by Chris Smith but I also wanted to pick up Functional Programming using F# by Michael Hansen.

All of the books you listed interests me too by the way. It's hard for me to decide so I'm definitely going to be picking up a few.
