CS50’s Introduction to Computer Science: A great step to get into CS world.

This is CS50 – an introduction to the intellectual enterprises of computer science and the art of programming.

CS50 is the largest course at both Harvard and Yale University and the largest Massive Open Online Course (MOOC) at edX with lectures being viewed by over a million people on the edX platform up to 2017.

CS50x, Harvard University’s introduction to the intellectual enterprises of computer science and the art of programming for majors and non-majors alike, with or without prior programming experience. An entry-level course taught by David J. Malan, CS50x teaches students how to think algorithmically and solve problems efficiently. Topics include abstraction, algorithms, data structures, encapsulation, resource management, security, software engineering, and web development. Languages include C, Python, SQL, and JavaScript plus CSS and HTML. Problem sets inspired by real-world domains of biology, cryptography, finance, forensics, and gaming.

Students who earn a satisfactory score (%70 and above) on 9 problem sets (i.e., programming assignments) and a final project are eligible for a certificate. This is a self-paced course–you may take CS50x on your own schedule.

What you’ll learn

  • A broad and robust understanding of computer science and programming
  • How to think algorithmically and solve programming problems efficiently
  • Concepts like abstraction, algorithms, data structures, encapsulation, resource management, security, software engineering, and web development
  • Familiarity in a number of languages, including C, Python, SQL, and JavaScript plus CSS and HTML
  • How to engage with a vibrant community of like-minded learners from all levels of experience
  • How to develop and present a final programming project to your peers

  1. Register for Edx
  2. Enroll in CS50x (take the course at your own pace for free. You will need to pay $90 USD for verified certificate later on)
  3. Once you enroll in the course, visit this link to start with Week 0. That’s it!

Note that there are 11 weeks, 9 problem sets and a final project. In each week, you will be watching lectures and then asked to solve the problem set of the week (some week have no Pset). I strongly recommend you to join CS50’s Facebook group where you will be able to ask a question when you are feeling stuck or contribute to others’ question. You will find all the details about the course in this link.

As a course taker, I can say that although I am an ICT teacher with some programming background, it has been challenging me since the beginning. I’m in Problem Set 7. Now, this is your turn!

Welcome to CS50!

Want to start your career as an Android Developer? Follow these steps.

If you want to start your career as an Android Developer or just learn how to develop mobile apps, then follow these steps.

  1. Sign up for a developer account (just $25) with a new email. Very Important!


  1. Get a good Laptop! Android Studio has a minimum hardware and software requirement. To avoid being a “frustrated cat”, i highly recommend you get a laptop with at least 8gb of Ram, an SSD for storage, 14 – 15.6 Inch screen and maybe a dedicated graphics card. Top 15 Recommended Laptops for Android Development & Gaming – 2018


  1. Go to Udacity sign up for the Android beginners course (it’s free!). Go through the course and finish it.


  1. After completing step 1, Buy and read this book Android Programming: The Big Nerd Ranch Guide (3rd Edition) (Big Nerd Ranch Guides): Bill Phillips, Chris Stewart, Kristin Marsicano. It’s a great book!


  1. Buy an android device. You don’t necessarily need a Samsung S9+. Just get a good one with stock android e.g Xiaomi Mi A1 – $130


  1. At this stage, if you haven’t started building your app ideas, now’s the time! As a beginner your app will probably suck, some functions won’t work, the UI might be horrible. Don’t worry about it, just keep doing your thing! Remember: Rome wasn’t built in a day, Strive for continuous improvement, instead of perfection


  1. Publish any App you write! Don’t get caught up in just the habit of just learning without creating your own apps. You learn best by doing! How To Create A Developer Account For Google Play.


  1. Attend (Coding) Meetups. Eventbrite  and Meetup are great resources to find events near you. Doing this will reinforce you to become a better Android Developer. “If you don’t have the burning desire for success, get it from people who do”


  1. Be prepared to get it all wrong and fail. Embrace failure as a process, not a finality. When you do (fail) remember these “The Master has failed more times than the beginner has even tried”, “Failure is the price of greatness. You’ve got to be willing to crash and burn”


  1. Learn Kotlin, Kotlin is way better than java for android development. learning Kotlin will save you from writing a lot of boiler plate code and help you write a more elegant and readable code.


  1. Teach others what you’ve learnt, this might be in a form of a blog post, video tutorial or stand up a presentation. Learn, teach, do is the formula to cement knowledge to your brain, FOREVER.


12. Things change really fast, never stop learning. The moment we stop learning             we stop evolving, when we stop evolving, we DIE!


  1. Sometimes read the official android documentation. It can be boring but you should consider as the gospel truth documentation of any Android API you’ll encounter.


  1. Learn to use git. Using git in Android Studio is surprisingly easy.


  1. Sign up on Stack Overflow.


  1. Stay hungry. Keep Learning. Keep Slaying!
