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.
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?
Java Design Patterns
-
Learn design pattern !
Java Design Patterns - IMO one of the most accessible sites with very easy explanations
-
What are the Java design patterns suitable for the below functions in an E-commerce application?
A hint: go to Java Design Patterns and go through the patterns to figure what could fit.

Show HN: I made a cheaper alternative to college-level math and physics tutoring
There is a Discord server for the OSSU computer science cirriculum that is pretty active. https://github.com/ossu/computer-science
-
Final project took me longer than expected, but I got there in the end.
For a well-rounded CS knowledge you might want to look into OSSU, which is designed to meet the requirements for univerisity CS courses.

Learning coding
There’s also a compiled CS curriculum here: https://github.com/ossu/computer-science.

Is codecademy worth it and where else can I learn
OP I hate to double comment and be "that guy who learned to code without going to college who MUST he did it the correct way" cause fuck "that guy". He's annoying, and he never shuts up, and I try really hard not to be that guy.... But I wanna provide some extra reasons I feel you should stay away from Code Academy. And as I said before, not because they're bad courses, so let me be that guy just for a brief moment. In addition to random Youtubers straight up having high quality courses that are much more update date, they often have supplemental tutorials on niche things that aren't covered in a "101 course". But even then, maybe the idea of a certificate on your resume appeals to you... Well, turns out there's more "academic" courses online you can do to get more of those things that self-taught dumbasses like me aren't as strong with because we skipped the "academic" part of learning..... If that's what makes Code Academy appealing (which I don't think they even go over much.... but still)... then here's 2 things I'd look at before pulling out your wallet. Here's Harvards entire introduction to Computer Science courses provided for anyone to take for free (you can pay for a certificate, but its straight up $0.00 to take the classes) Heres a github repo for an Open Source University that a ton of devs have curated to give a simulated full degree program If you want to focus hardcore on being a Web Developer and are frustrated by there not being tutorials that show you exactly how to handle every step from "there's no website on my computer" to "holy shit I made a website", then here you go The Odin Project is an Open Source answer to your cries of frustration. It has curriculum paths that do exactly that. The goal is to go from zero programming knowledge to fully employable as a web developer (by skill level at least, obviously you'll need to build stuff and build a resume)

CMV: People should not be referred to as "Engineers" unless they have a degree in the appropriate field
That said, I'm a software developer and I don't see any point in the distinction of calling someone a software or computer engineer based on education (with the exception of electronics engineers that work on hardware, but here I'm talking about software). A BSc or BEng in computer science or software development can give you a headstart but nothing that can't be self taught and in hiring I've been shocked by many postgrad engineers that couldn't answer simple questions and were outdone by self taught engineers. Make no mistake though - education is required (e.g. you're not going to learn data structures and algorithms through osmosis), but it doesn't have to be formalised as a degree.

After finishing cs50 python, what’s next? What did everybody do? I see there’s an ai course in python.. but not sure if im ready for that yet..
My plan is to follow the training program that the OSSU (Open Source Society University) provides in order to really delve into the topic and learn more. Check out this link for more info: https://github.com/ossu/computer-science

NÃO QUERO FICAR PARA TRÁS!
se vc quer literalmente ficar a frente do seu curso, ent é só usar o ossu/computer-science.
- What is the best low level programming language to learn for someone who knows only python?
-
I want to be a software engineer?
If someone's completed CS50X and W any recommendation where to carry on https://github.com/ossu/computer-science I'm thinking from core maths onwards seems reasonable.
-
My university spits out mediocre professionals, but I want to be more
For fundamentals, https://github.com/ossu/computer-science is a reasonable way to make sure you're covering them.
