I just learn whatever is needed for the product I want to make. After being a programmer for a long time it's very easy and fast to learn basically whatever.

#192I came here to tell OP to spend the time learning something like Terraform because it is not a trend or a fad, has wide adoption by the enterprise, gets them closer to the metal in understanding how everything works and will almost definitely help them in their career. I've instead found a flame war with someone presuming a person's age and preceding to talk about how much better they are ... oh HN why does it always…
Not just Terraform, but the rest of the Hashicorp suite is powerful and relatively easy to pick up. At the tail end of last year I taught myself Terraform and I'm looking at Vault next.

#193For the love of christ please learn some object oriented programming or invent something using which you can write more than 100 lines of code which does more than solving a leetcode problem.

#194It's not a 'hottest tech stack', but I would suggest people take 2020 to learn testing. TDD/unit/browser/whatever - look to incorporate testing in to your work more often. For me, that has meant making sure code you're writing is testable first. I don't do hardcore TDD, but often am writing tests more or less concurrently with little bits as I'm writing those bits. I don't do this for every single project all the tim…
How is this something to learn? It's more of something to try. Anyone who can write code can write tests and anyone who can write tests can writes tests before they code. It's trivial. Instead learn formal methods. Learn how to prove your code correct for all cases rather then verifying your code for one test case. This is learning and it won't be rehashing what you know like tdd. Formal methods is brutally hard.
The concept is easy to grasp, but for me the challenge is figuring out which testing framework/suite is best for the language I'm dealing with (and then learning the intricacies of how the tooling works).

#195For my own learning, I'm pursing three things:
1) Elixir: since I teach it, I pretty much need to keep digging further and further into its ecosystem, looking for useful things to share with my audience and looking for better ways of building things. For example, the series I'm in the middle of is on LiveView and the next in my queue is on Absinthe/GraphQL. I knew nothing about LiveView a year ago and spent a good amount of time last spring struggling with various Absinthe-related tasks. A year from now there will be even more "must-learn" libraries.
2) The intersection of development and marketing: as a developer, there are marketing systems I can build by myself that would be very difficult for most smaller online businesses to do, but also highly valuable. I've been taking some of Brennan Dunn's courses (working on his ConvertKit course at the moment) and it's been one of the best investments I've made.
3) Rust: I don't have any business reason to learn Rust at the moment. However, it's a particularly good complement to Elixir. Elixir's strengths are stability and productivity, but it's a bit weak in brute force number crunching. Compiling natively invoked functions in C/C++ has been a thing for a long time, but at a terrible cost. If those functions trigger an exception, they can take down the entire EVM, negating the famous stability of Erlang/Elixir. Rust, on the other hand, is very good at making the most of the CPU and memory available in a manner that guarantees safety. So NIFs written in Rust can be used in Elixir projects without fear!
I'm also interested in using Rust with WASM, so there are multiple ways I can see learning it paying off down the road.
For anyone out there learning Elixir: You might want to check out Alchemist Camp. I've had overwhelmingly positive feedback from people who have used it to learn Elixir from scratch (https://alchemist.camp/episodes, scroll down to the bottom and click Lesson 1)

#196If you are on the java platform I have an unpopular recommendation: get familiar with OSGi. Its specs, its history and its core concepts. The learning path you go will teach you a lot about how to build systems, how to think about api design, modularisation and standards (compared to one-off company owned tech). Its almost certainly makes you a better developer/thinker.

#197Learn how to really use a relational database, relational data modeling, and SQL. Not knowing of their capabilities may lead you to unnecessarily complicating your tech stack. You can go a really long way with just this domain of expertise. From there, do the same with whatever key-value store interests you (for me, it's Redis). Python isn't known for high performance but when a django web app uses a cache and relati…
What resources do you recommend for learning relational databases and key value stores really well?
+1 started my third month as data engineer straight out of college and notice I am missing some solid RDB resources

#198Quantum logic and programming. Given the demonstration of quantum supremacy, AWS expanding into QC with their Braket service, and MS releasing Q# in 10-20 years this will be one thing you will want to have learned. All of the silly JS frameworks can wait. The ML world gains massively due to underlying speed gains of QM. Security considerations will have to change drastically. Having a head start here is extremely valuable given the steep learning curve of QM/QC.

I absolutely agree, Rust and Elixir are an amazing couple of languages! I recommend reading https://blog.discordapp.com/using-rust-to-scale-elixir-for-1...

+1 for relational models. All data access is relational in some way, and knowing how to efficiently access/index the data is an important step for building efficient applications.
I've come to a realization. Domain data is basically always relational. Configuration data may or may not be. Where it's not, NoSQL is good for configuration data.
