I am developing a multiplayer RPG-like strategic combat game.  If I use the formulas of Pokemon games in this game for damage calculation, does I risk any copyright issue ? What areas of the game is copyrighted ?
Most games build on other games' successes and many are downright clones. Where is the limit of imitation before legal issues come into play? Is it down to literary or graphic work like characters and storyline that cause legal problems, or can someone actually claim to own gameplay mechanics?  There are so many similar clone games out there that the rules are probably very slack or nonexistent, but I'd like to hear the views of more experienced developers / designers.
Why can't a CNAME record be used at the apex (aka root) of a domain? Is lemonade better when made with simple syrup? On a hot summer day and with a basketful of lemons I often want a nice cold glass of lemonade. A lot of recipes suggest making lemonade with simple syrup, which requires cooking, whereas other recipes just have stirred-in sugar.  What exactly are the benefits of making lemonade (or limeade) with simple syrup versus just stirring in sugar? I'm going through MSIL and noticing there are a lot of  instructions in the MSIL.  The MSDN article says they take no action and are used to fill space if the opcode is patched. They're used a lot more in debug builds than release builds.  I know that these kinds of statements are used in assembly languages to align later instructions, but why are MSIL nops needed in MSIL?  (Editor's note: the accepted answer is about machine-code NOPs, not MSIL/CIL NOPs which the question originally asked about.) I would like to create some kind of feature matrix with available classes in columns and implemented features as rows. Problem is, that the class names are quite long.  Rotating them by 90° simply looked quite silly, so am looking for alternate ideas.  The only idea I had so far was to write the heading text horizontally with a arrow (or similar) matching the "heading row" with a column. But frankly I have no idea how to do something like this in latex.  An minimal example of my naive approach looks like this.  \documentclass{beamer}  \usepackage{tabularx}  % I am actually using a custom theme % The space ``wasted'' is similar for PaloAlto though \usetheme{PaloAlto}  \begin{document} \frame {   \frametitle{Comparision of boost implemented graph classes}   \begin{tabularx}{\textwidth}{X c c c}     %     % Column Headers, first column is empts     %     & \rotatebox{90}{adjacency\_list}     & \rotatebox{90}{adjacency\_matrix}     & \rotatebox{90}{compressed\_sparse\_row\_graph}      \     %     % Rows, I suspect I need about 10     % Class               adjlist          adjmatrix     csrg     \hline      AdjacencyGraph        & Yes            & No          & Yes \\     Interface \#2         & Yes            & No          & Yes \\     Interface \#3         & Yes            & No          & Yes \\     Interface \#4         & Yes            & No          & Yes \\     Interface \#5         & Yes            & No          & Yes \\     Interface \#6         & Yes            & No          & Yes \\     Interface \#7         & Yes            & No          & Yes \\     Interface \#8         & Yes            & No          & Yes \\     Interface \#9         & Yes            & No          & Yes \\     % Rest omitted   \end{tabularx} } \end{document}    If its important: I am doing this for a presentation with beamer. Open an app on startup/after booting I need to force a selected application to start up each time my Android-based device is (re)started.  Is there anything I can use (configuration setting, external application etc.) to accomplish this task? Or is this kind of behavior limited to home screen managers only? How to reinstall Ubuntu in dual boot with Windows 10? I have Ubuntu 15.10 and Windows 10 dual-booted, but I want to reinstall Ubuntu in the same partition without making any changes or causing problems in the dual boot option and without removing Windows.  Is it possible? Any guide on how to do it? Omitting the hypotheses of finiteness of the measure in Egorov theorem I want to prove that if I omit the fact that $\mu (X) &lt; \infty$ in Egorov theorem and place instead that our functions $|f_n| &lt;g$ and $g$ is integrable, we still get the result of Egorov's theorem.  Fix $m$ a natural number.  I took $ w_{n} = |f_n-f|$ and thus by DCT $\int |f_{n} - f|$ goes to zero.  Then I took $\bigcup_n {( w_{n} \geq 1/m)}$. I need its measure to be finite. Its measure is less than the sum of the measures of each $ w_n\geq 1/m)$ varying $n$, and by Tchebychev, this is less than $m\int|f_{n} - f|$.  But I got stuck here.  Any help is appreciated. Thanks!

I need to illustrate a 2D array data structure in my document. This is a picture I found on the internet. I want something similar.    I also want to show the memory layout in the illustration.

I would like to create a growth graph showing when servers and databases were added to the environment either/both monthly or annually. I executed the following query using the SSMS multi-query feature with only partial success.  SELECT [name], create_date FROM sys.databases   It's partial success because the master and model databases return with a date of 'April 8, 2003' when I know that I created some of these servers during the past couple years.  I refresh databases from one server to another several times a week, which appears to be causing issues with the database create date.   Is there a simple method to determine the actual create date for both servers and databases? Proof that disjoint cycles commute The preimage of continuous function on a closed set is closed. Seem to have lost 4 Silver badges and 10 Bronze badges In the film and book series, Year 4 (Goblet of Fire), how is it Mad-Eye Moody/Barty Crouch could see Harry through his Magical Eye even when he was under the Invisibility Cloak?  As the cloak is a True Invisibility cloak, immune to charms and spells, and according to legend invisible to even Death, how did Mad-Eye detect Harry Potter under the cloak? How Nagini and Mrs. Norris were able to sense Harry were through other senses, such as smell and warmth, but not visually.  I'm referring to the scene/chapter where Snape follows Harry at night. Harry hides under the Invisibility Cloak but his foot is stuck at the broken staircase. Eventually Mad-Eye arrives, sees Harry through his Magical Eye, and talks Snape away. $ \int_{-2}^{0} \frac{x}{\sqrt{e^x+(x+2)^2}} dx $ = -$  2.887270... $  The function has no antiderivate and there's no symmetry here to help, if you solve this I would be thankful if you would for a highschooler ^^ Cannot see my wifi [10ec:d723] when trying Ubuntu Find $\sum\limits_{k\, \text{ odd}} \frac{2(k^2-1)}{k^4+k^2+1}$ Fastest Gun in the West Problem I feel like there's a problem with Stack Overflow, as the number of people prowling it increases.  Each question's answers are sorted by descending score and then by descending time of posting. This means that if a person sits down and answers a question in a long, thorough way, going through every nook and cranny, once they post their answer, it will already be one of about seven different ones, some of which have already been upvoted. This wouldn't be a problem if those answers were as thorough as the one this guy's posting, but they usually aren't. Some of them are downright wrong, some aren't even answers to the question asked because their poster didn't bother to read the question all the way through.  This causes a problem I like to call Stack Overflow's Fastest Gun in the West Problem. I've come to a point where I'd rather just send a short, simple, correct explanation, than to go and do some proper research, write a whole blog post about it or even make sure the code I post even compiles, just so it will be noticed, as opposed to the incorrect ones.  I'm sure I'm not the only one doing this and that it despairs many people from even trying to answer questions.  I've long ago learned to try to always raise a problem with a solution in hand, rather than just say "This is a problem, handle it," so my question, after this long tirade, is:     How do you think this can be changed? What would you change in Stack Overflow to make this problem go away without hurting the site?   I promise to vote on answers I like, even if it takes you a long while to post them. :) Challenge room locked though I have full health I thought these opened if you have full health. I actually had full + 2 blue hearts before dropping a bomb on myself before taking the screenshot.   But even here I have full health... right?
