The number of mentions indicates the total number of mentions that we've tracked plus the number of user suggested alternatives.
Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

What is the weirdest or most interesting piece of code you ever had to write?
Wrote the code to convert CQEngineCQEngine queries into Solr search queries.

Looking for: library to turn SQL (or abstracted) to code & execute against custom backend (slice of structs)
It seems that you're looking for something like https://github.com/npgall/cqengine but unfortunately I'm not aware of any equivalent in Go. LINQ is similar. I'd probably try searching for "LINQ in go" or something like that.

Evaluating Range Predicates over Java collections
I wonder if there's a huge difference in efficiency between RoaringBitmap and CQEngine. I used CQEngine a few years back and it turned out really great. Never tried RoaringBitmap, though.
- CQEngine for Java Tutorials/ Guides / Books?
- Ideal Datastructure for Multiple Keys mapping to Multiple Values?

Top 10 GitHub Repositories for Python and Java Developers
2. Java Design Patterns This repository showcases a collection of design patterns implemented in Java, making it a useful resource for learning how to apply design patterns in your projects. https://github.com/iluwatar/java-design-patterns

I have been following the mooc java-1 from few days and i am on part-3 i want to ask some questions
After that, more practice, and then Design Patterns (as in the famous book of the "Gang of Four": "Design Patterns: Elements of Reusable Object Oriented Software"). Here I'd recommend "Head First: Design Patterns" and Java Design Patterns as well as Refactoring Guru (the sites are more reference than course).
-
I made java roadmap website! Any feedbacks welcome!
For Design Patterns - any resource recommendation that misses Java Design Patterns and Refactoring Guru (also for Refactoring) as well as *Head First: Design Patterns, has failed.
-
How do you structure code?
A massive list of design patterns and how they could be implemented (in Java) can be found here.
-
Resources to learn how to create a 2D game engine with CPU rendering.
https://java-design-patterns.com/ has example code for things like object pools that can help with memory management.
-
What are some book recommendations that don't require a specific language.
Sidenote: I would not really use the GoF Design Patterns book anymore. Too dry. I would use "Head First: Design Patterns" - much more modern, much easier to read, or Refactoring Guru or Java Design Patterns (uses Java, but again, only for illustrations).
-
I want to get a book on design patterns. Would you recommend the GOF book or the Head First design patterns one?
Also: https://java-design-patterns.com and https://refactoring.guru/design-patterns
-
How is an Observer pattern possible?
Use either Java Design Patterns or Refactoring Guru. Both resources are far higher quality than yours.

Are there any quick videos/articles/resources that go over stuff not explicit taught in University?
