Unlike Ocelot20, I have quite a lot of Android experience, and this answer will focus on only one thing, namely:
Getting rid of the Singleton pattern in Android

Luckily, I can say "Been there, did that, don't do that anymore"
Hm. I've just come across an old Hangman game I've made some time ago. It still sucks (using namespace std and raw pointers), but I'll refactor it and post it for review sometime.
I put together this Ruby script (1.9.3) to load data into MySQL from many xlsx files that contain data entered by people. These files typically have many illegal characters and it has been difficult to handle the different errors. I have tried a multiple rescue and character escaping approaches b...
@rolfl Just thought of something... Your Zombie-over-time-query, perhaps that should be adapted to show the percentage of Zombies over time... I mean, for sites such as SO and Programmers, there's no doubt in increasing Zombies. As number of total questions goes up, so does the Zombies. But if a site is able to keep it's incoming Zombies in check so that the percentage of Zombies remains the same, that's another question...

@JerryCoffin: What would be a good way of selecting a random element from a std::vector, using <random>? I've found one SO question about this, but it uses std::rand.
size_t index = std::uniform_int_distribution<size_t>(0, array_size-1)(std::mt19937());
Depending on the situation, you may prefer to define objects for the generator and/or distribution before using them, but that's kind of the general idea anyway.
I'll revisit it, then. I'm still working on other parts of my Hangman game. I don't even want the original working version reviewed as it no longer represents my best work.
My goal is to make File_Path_Handler constructor the only thing a user can access.
The handler:

//| imports

System I'm building has Users and Articles. Users can upvote/downvote Articles and cancel their votes if they want to. Each vote changes article's score. Score equals to sum of all vote values together.
So I created three models: User, Article, ArticleVote. Even though the most natural way for m...

Floating-point math is challenging in surprising places. It's easy to write down a reasonable algorithm that introduces 0.01% error on every step, which over 1,000 iteration turns the results into complete slop. You can easily find volumes fill...

@Pivo Nah, it's alright. I enjoy it, though I can be quite picky about some edits. Though, with yours, you seem to have trouble formatting code correctly. The Markdown Help should be helpful.
I've been thinking of taking a second language after learning my first, java. Which one to take, I'm unsure of though. Something to research in my spare time.
I am doing a project for school and had to create a function to check if 2 time ranges overlap . I searched the net a bit but failed to find a simple function to do that . I played around a bit with my code and i think i created a working one .
Note , it works for 24 hour times only & don't forg...

I'm going to add some methods after I get it running to help organize it, but I think my problem lies in understanding for loops and storing the unique number to the array properly.
There are two versions of code in your question right now, the first version does not compile, and the second version does not produce meaningful results.
@Pivo Wish you were using C++, so you could just call std::unique to do most of the work (or, as I mentioned in my comment on the question, use a set).

Speaking of C++, @JerryCoffin, I'm in the process of retagging questions as c++11. I'm looking for valid questions by searching for "auto" and verifying each question.
@Jamal Other potentially useful searches: [], [&], [=] (catch many uses of lambdas). <random> (new PRNGs), and wish for regular expressions so you could do something like for\w([^:]+:
