17,054,522 | 0 | <p>As said, you're asking about regular expressions commonly called a "regex". Take a look at <a href="http://www.regular-expressions.info/reference.html" rel="nofollow"><strong>Regular-Expressions.info</strong></a> for tons of good information. The page you're probably most interested in is the <a href="http://www.regular-expressions.info/characters.html" rel="nofollow"><strong>Literal Characters and Special Characters</strong></a>, which largely answers your OP. A great site to test your regex is <a href="http://www.rubular.com/" rel="nofollow"><strong>Rubular.com</strong></a>. It's designed for Ruby, but works great for nearly anything I've thrown at it (sed expressions, C# replace, JS replace, etc.).</p> <p>HTH</p> |
1,458,212 | 0 | <p>My interpretation is that it will always interpret it in a format that <em>happens</em> to look a lot like C#, yes. So <code>.</code> for members-access, etc (the same as data-binding uses <code>.</code> for member-access, regardless of the caller's language). It is also a lot like the <code>string.Format</code> pattern, if you see the relationship (<code>"{0} - {1}"</code> etc).</p> <p>Of course, if the expression gets <em>too</em> complex you could consider a <a href="http://msdn.microsoft.com/en-us/library/d8eyd8zc.aspx" rel="nofollow noreferrer">debugger type proxy</a>.</p> |

17,119,796 | 0 | <p>While there is a file system provider <code>s3fs</code> build on fuse. Is not always a good idea to try to mount it to the file system. Instead you should either use command line tools <code>s3cmd</code> or build in access to s3 into your filesystem.</p> <p>The reason why I would recommend against it is that s3 is not a block device while the rest of your file system is. Everything on s3 is treated as a complete object. You can't read or write to a block of the object.</p> <p>If all your are doing with the mount is copying files in its entirety to and from s3, a file system mount may work reasonably well. But you can't run anything that would expect block level acccess to files on that mount.</p> |

So I need a new data structure to store UUID according to index order, perhaps something like this:</p> <pre><code>private SomeStructure<UUID> myDataIndex; </code></pre> <p>What I want is this <code>SomeStructure</code> class. It should have a public method such as:</p> <pre><code>public UUID getUuidByIndex(int index); </code></pre> <p>And, it should sort UUID elements by MyData.data1 field.</p> <p>And, every time I put an item to <code>private Map<UUID, MyData> myData</code>, the item's UUID is also added to <code>private SomeStructure<UUID> myDataIndex</code>.

39,329,146 | 0 | <p>When a server listens on a computer, it specifies a port it wants it's connections coming in from , so ports are important for setting up servers. This is useful as you can have multiple applications listening on different ports without the different applications accidentally talking to eachother. So you should decide on a port that isn't a standard( 80 is for HTTP for example) to exclusively use for you gameserver so the client knows which port to send the requests to.</p> <p>If you want to handle multiple connections at once the best thing to do is threading.</p> |

18,088,595 | 0 | <p>I think the main confusion here is the notion that that <code>main</code> is the first and last thing that happens in C++ program. Whilst it is [1] the first part of YOUR program, there is usually some code in the application that sets up a few things, parses command line arguments, opening/initialization of standard I/O (<code>cin</code>, <code>cout</code>, etc) and other such things, which happen BEFORE <code>main</code> is called. And <code>main</code> is essentially just another function, called by the C++ runtime functionality that does that "fix things up before <code>main</code>". </p> <p>So, when <code>main</code> returns, it goes back to the code that called it, which then cleans up the things that need cleaning up (closing standard I/O channels, and many other such things), before actually finishing up by calling some OS function to "terminate this process". As part of this "terminate this process" functionality is (in most OS's) a way to signal "success or failure" to the OS, so that some other process monitoring the application can determine "if all is well or not". This is where, eventually, the <code>0</code> (or <code>1</code> if you use <code>return 1;</code> in <code>main</code>) ends up. </p> <p>[1] If there are static objects with constructors that are part of the user's code, then these will be performed before any code in <code>main</code> [or at least, before any code in <code>main</code> that belongs to the user's application] is executed. </p> |
25,212,096 | 1 | Editing Original DataFrame After Making a Copy but Before Editing the Copy Changes the Copy <p>I am trying to understand how copying a pandas data frame works. When I assign a copy of an object in python I am not used to changes to the original object affecting copies of that object. For example:</p> <pre><code>x = 3 y = x x = 4 print(y) 3 </code></pre> <p>While <code>x</code> has subsequently been changed, y remains the same. In contrast, when I make changes to a pandas <code>df</code> after assigning it to a copy <code>df1</code> the copy is also affected by changes to the original DataFrame.</p> <pre><code>import pandas as pd import numpy as np def minusone(x): return int(x) - 1 df = pd.DataFrame({"A": [10,20,30,40,50], "B": [20, 30, 10, 40, 50], "C": [32, 234, 23, 23, 42523]}) df1 = df print(df1['A']) 0 10 1 20 2 30 3 40 4 50 Name: A, dtype: int64 df['A'] = np.vectorize(minusone)(df['A']) print(df1['A']) 0 9 1 19 2 29 3 39 4 49 Name: A, dtype: int64 </code></pre> <p>The solution appears to be making a deep copy with <code>copy.deepcopy()</code>, but because this behavior is different from the behavior I am used to in python I was wondering if someone could explain what the reasoning behind this difference is or if it is a bug.</p> |
