Because I am often asked by friends where to start as a beginner in computer science and software development, I compiled a list of a few of my favorite resources. This list may be updated from time to time. Have a suggestion? Contact me so I can add it.
This is not an exhaustive list. You can find many more coding resources at code.org.

My Favorite Books
System Programming by Lawrence Angrave – free wiki book – one of my favorite books on System Programming in C; written by Lawrence Angrave, who is a professor at UIUC.
Programming in Objective-C by Stephen Kochan – Great intro to Objective-C. You can use Objective-C to create iPhone apps.
Effective Objective-C 2.0 – A helpful book to take your knowledge of Objective-C to the next level, by diving deeper in several areas.
Game Programming Patterns – Great discussion of various patterns for game programming. The patterns are also extremely applicable to other types of applications, besides games.
App Empire by Chad Mureta – An introduction to creating iPhone apps from the sales/business owner perspective. No programming tutorials, but a solid introduction to the app marketplace.
Building Blocks for Theoretical Computer Science – Also listed above under “CS Theory”. An excellent introduction to discrete mathematics.
The Vital Parts of UIUC’s CS curriculum
Sometimes, aspiring programmers are concerned that they don’t know what they need to study to be a successful computer scientist or software engineer. And outside of academia, it can be tough to form a complete image of what a well rounded CS curriculum should look like. The CS program at UIUC is excellent, so I believe that if you follow the core curriculum, and learn the material covered, you can be a successful computer scientist or software engineer.

List of required classes to acquire a CS degree at UIUC
CS 125 – Introduction to Computer Science. This teaches basic computer science and programming principles. There are also other great ways to get started on this post.
CS 173 – Discrete Structures. You can learn this material by reading Professor Fleck’s excellent textbook. Prerequisites: CS 125, calculus 1
CS 225 – Data Structures. The class serves as both an introduction to data structures, and an introduction to C++ skills. Check out Cinda Heeren’s CS 225 course website. And here is a free data structures textbook. Alternatively, Google for introductory Data Structures courses. Here is a Coursera Data Structures course. Prerequisites: CS 125, CS 173
CS 233 – Computer Architecture. This is a great class which teaches you how computers work at the level of chip design. MIT has a similar class, 6.004, which is available for free online. Prerequisites: CS 125, CS 173. Prerequisite or concurrent: CS 225
CS 241 – System Programming. This is an extremely valuable class, and I feel it has been instrumental in my early career and internships. It teaches you C and System Programming and some Bash. You can learn most of this by reading Professor Angrave’s excellent open source wiki book. It’s helpful to have access to a Bash terminal. If you’re on Windows, you can now install Bash. You can also check out Learn C the Hard Way. Here is a C programming course on Udemy. (but it isn’t free.) Here is a free Bash course from Stanford. Prerequisite: CS 125, Prerequisite or concurrent: CS 173
CS 242 – Programming Studio. Great class with a lot of hands on work. We spent time each week learning new programming languages, and creating new projects with those languages. It’s an overview of how to work as an effective software engineer. This class’ content is being migrated into CS 126. Prerequisite: CS 241
CS 357 – Numerical Methods. Prerequisites: CS 125, Linear Algebra, Calculus 3.
CS 361 – Probability and Statistics for Computer Scientists. Professor Forsyth’s textbook is excellent. Prerequisites: calculus 1, matrix theory
CS 374 – Algorithms. This is the content you need to pass whiteboard/interview questions at top companies like Google. Read Professor Erickson’s notes. Coursera has free algorithms courses, too. Prerequisite: CS 225, linear algebra
CS 421 – Programming Languages. This class makes you a more efficient software engineer. You learn lambdas and functional programming, and also how interpreters work. A lot of the course’s material can be learned in the book “Learn You A Haskell for Great Good!“, which the author offers as a free web book, or you can purchase it on Kindle. Here is a free course on functional programming. Here is another free course on functional programming. My recommended prerequisite: CS 241. Actual prerequisites: CS 233, CS 374
