Can I make a difference at an open source project?
I haven't gotten a degree or anything but I am really interested in computer science and I have most of the fundamentals down.
Is there a project I can make a difference at? If not, any sites where I can further my knowledge and review the fundamentals (advanced concepts as well) of computer programming?
Scour around GitHub for projects, there are plenty that could use some help.
At the very least, write tests for untested code and submit them back. Even the littlest of contributions are appreciated.
Newcomers to an active Open Source project often feel like they are walking into a busy kitchen. A lot of different things going on and you feel like you are just in the way.
But often its not the case.
I can't point you to a specific project since i do not know your skillset or what you want to focus on.
Getting into an Open Source project can take time, its mostly based on the size of the project but usually its trying to see what is needed.
What i recommend is the same most people do, find a project that inspires you to make it better (even though its good to begin with), since that will make you want to stick around during the harder times.
Absolutely. Writing documentation and unit tests is good advice, but I'd suggest instead you find something you're particularly interested in, perhaps a piece of open source software you already use, and add a feature that you yourself want to use. It'll be more difficult, but it'll actually keep your interest and get you real world experience. Worst case your patch won't be accepted, but if it's a decent project they'll tell you why and what you need to do to make it acceptable.
Or, pick a small problem you want to see solved, and write an open source solution for it. The key is actually be interested in the problem you're solving.
Open source software is not magically high quality code; in fact it's not unusual to find sloppy code and practices. Don't be intimidated, jump in and give it a try. My first piece of open source still has a few users over 10 years later, but the code quality makes me cringe everytime I look at it.
You can visit Sourceforge.net and look for projects that need help.

I know there is no clear answer to this question. I still wonder to know whether Reading open source code can improve myself rapidly? how and why?
ps：I keep reading open source code every day for months.
Well, many of the bigger open source projects are collaborations between many people: Thus you do have a chance of finding a project written by good developers, and therefore improve your own coding style. Of course, it all depends if you actually memorise the stuff you read or not - But I guess you wouldn't really read that much code if you didn't.
In my opinion, you can learn the following from well-written projects:
Coding conventions
Solutions to common problems (Of course, this depends heavily on the "type" of the project)
How to document code properly - If multiple people work on something, and the project is well-written, it probably also has a good documentation.
Of course, all of this is opinion-based, so you need to see for yourself.
Possible answers (this is highly subjective)
Because working with someone else's code is more difficult than working with my own code. It forces me to adapt to some else's thinking ("If all I have is a hammer, every problem looks like a nail")
Because open-source code is often not written under a deadline, by people who enjoy what they are working at, and can provide high-quality real-world examples
Because open-source code tends to have less of an agenda to push vendor XYZ's proprietary pet technology
Because the world might become a slighly better place, if people wouldn't code for the CPU as their main audience, but a human reader :)

Background: There are a couple of concerns that are not core business for us. They are essential to our core business, but we have no business writing on our own, in terms of manpower, time, and expertise. I am familiar and very comfortable with some open-source implementations, using closed-source-friendly licenses, that could fill these gaps. Closed-source alternatives I either could not find, or were crap.
I put together an informal proposal to show my boss, including the original licenses for each project for legal review. Being a business owner that knows little about the world of open-source, he was initially hesitant when he realized some of these libraries were. I tried to educate him to the best of my abilities (I'm no open-source warrior myself), but he did bring up some valid questions that, in some cases, I don't feel I answered as well as I could have.
Concerns (worded from my boss's prospective)
How do we know and ensure there is no malicious code in an open-source project? Read and understand every line? At that point we could have just written it ourselves!
Who do we blame when things go wrong? With support licenses and a responsible party, we can get things fixed. And if they fail to come through, well... you know.
How do we establish or measure that an approach or implementation in an open-source project is sound, efficient, or good quality?
What sort of liability do we open ourselves up to, in terms of licensing [granted, this is more a question for lawyers and an issue of RFTL].
Question: How have or would you have addressed these concerns?
How do we know and ensure there is no malicious code in an open-source project? Read and understand every line? At that point we could have just written it ourselves!
Same problem with closed source. Actually worse with closed source. With open source at least you CAN review it yourself, or you can take someone else's word for it. With closed source, taking someone's word for it is your only option.
Who do we blame when things go wrong? With support licenses and a responsible party, we can get things fixed. And if they fail to come through, well... you know.
Probably the biggest issue. This depends on which particular solutions you're using. Some things are backed by a reputable vendor (e.g. Red Hat) whereas others have virtually no support. But that "you know" is critical here: ultimately there is no way to guarantee that someone will fix bugs that you encounter when you are using closed source. At least with open source you can hire a 3rd party consultant to do the job, for the right price, because you have the source.
How do we establish or measure that an approach or implementation in an open-source project is sound, efficient, or good quality?
The same way you would with any other code? I don't have any better answers for this one.
What sort of liability do we open ourselves up to, in terms of licensing [granted, this is more a question for lawyers and an issue of RFTL].
Yep, have a lawyer advise you on this. Every tech business should employ a lawyer anyway. The answer will depend on the specific licenses you're dealing with and what exactly you plan to do with the software you develop.

in the past few weeks I have heard about a phenomenon called 'code-kata'. When I get it right, it means coding an exercise again and again. What is its point? Does it improve your abillity to design better software? If yes, why does it do so?
This was the first time I've heard of this, so after a quick google, here's my gut reaction:
Code Kata is not repeating an exercise over and over again. Rather it's about constantly expanding your "comfort zone" so you can grow as a developer.
Simply working on projects that you know how to do won't help you. You need to try and tackle projects that you would most likely fail at on your first attempt.
The end goal is that if you continuously try, fail, try again, fail again, etc, sooner or later you will succeed. When you do, you've mastered some new knowledge, and become a better developer.
Enough repetition of this will obviously improve your skill.
(Sorry if it's a bit of a brain dump)
I collected a bunch of references here: http://slott-softwarearchitect.blogspot.com/2009/08/code-kata-resources.html
The most important of these is http://codekata.pragprog.com/
It's not primarily to improve your design skills, rather it is a way to improve your productivity in your chosen IDE.
Repeating a familiar task over and over again allows you to watch out for and take advantage of IDE shortcuts and features that you were previously unaware of to shave seconds from your time. It will also help you find any unnecessary steps you take out of habit so you can cut them out of your routine.
We tried a few of these at my company, our thoughts were to develop a simple game (obviously something with a bit of logic we'd not know how to do). We'd all have a go at doing it, then we'd keep improving it as much as we could until we thought we had the best way to do things, then we'd meet up again maybe a week later and compare our results. It's interesting to see how different people come up with different solutions, and everyone learns from the experience. Maybe not a proper kata, but we always try and bend these things to something we'd find useful :)

I always have found the open source space interesting but have never actually participated in any projects. I recently had what I thought was a great a idea that was different from other projects I had seen in the area (in case it matters it was a .NET DI framework).
My question is if I have a funky idea should I join an existing project and share my ideas or create a competing project with exactly what I want. There are a few projects in the space the are similar to what I was thinking but they don't quite capture the same ideals.
Is extra competition frown upon in the open source space?
Competition is as important as collaboration in open source. Assuming the licenses are compatible, features and ideas can be cross-pollenating. Everybody wins.
the short answer to this is another question: do you want to contribute to a discussion, or do things your way?
You may want to consider writing it your own way and turning that process into an article that you could submit to CodeProject. Then if there seems to be interest in the article, add it to SourceForge. I've seen a lot of tools and widgets get a quick audience and coding help that way. One that I use often is XPTable, which started as a CodeProject article and eventually became an open source project on SourceForge.
BTW, you'll know if its a hit, because you'll start to get lots of requests for improvement, or people even submitting their own fixes and enhancements to your article.
Thank you for your time. I have decided to contribute directly for the project in some areas they were hurting. By doing so I can help the project and learn from the masters.

What open source projects would you recommend as a good place for a starting open source developer? Factors that I think would be important are some obvious ones like well written code and a community that is helpful to newbies. But it might be nice if the code base is such that I can start hacking some small problems without really understanding the details of how everything works.
I'd prefer something that can be developed on Linux using C/C++/Java/Python/Scala.
Trying to pick a project like that will never work because it's not something you're passionate about. What's an open source project that you use daily or enjoy using? Go work with that one.
It really depends on what your interests are as to what project to dive into.
Rationale for a larger project (e.g. Firefox, OpenOffice, etc) is that it has many developers, a well established code base, and many small tasks/bugs to be worked out.
Rationale for a smaller project is that you will become more intimate with the code and application. You will likely get to know other developers on the team and understand the overall concept better. Additionally, your additions to the project may be more noticeable.
sourceforge has a list of projects seeking a new developer. Therer are several for your requested programming languages:

Apart from developers they have more help requests:

Pick one you use and like already.
