17,353,988 | 0 | <p>I would say that the real reason is that try-with-resources isn't so much new JVM feature as it is a compile-time language feature. In this way, it is very much analogous to the "enhanced for statement" which requires a class that has implemented the Iterable interface (you have to name an instance of the implenting class there, too). Try-with-resources requires that the resource implements the AutoCloseable interface. It is not wrong to regard the block as "syntactic sugar, introduced in 1.7". It just prevents you from having to deal with calls to the interface method yourself.</p> <p>Because the feature requires an object whose class has implemented the interface, you must give the try-with-resources block the name of that object.</p> |

1,867,590 | 0 | <p>I've used Selector for the last couple years and found it perfectly stable. It's been at 0.8.11 for at least two years now. </p> <p>I would draw two conclusions from that: </p> <ol> <li><p>It could be basically unmaintained. If you find a bug in it or need a new feature, I wouldn't count on being able to get Luke Arno to jump up and fix it in a hurry (not saying he wouldn't, but I'm guessing that Selector isn't his main focus these days). Would you be comfortable maintaining a local fork in that case?</p></li> <li><p>It's pretty much complete. The problem that it's trying to solve is contained in scope. It's a very small library without much code. The bugs have been shaken out and there's really nothing left to do on it. I think this is the main reason it hasn't been updated in a long time. It's basically done.</p></li> </ol> <p>Open source developers, and Python developers in particular, have a long history of being very (probably overly) conservative about marking things as 1.0. The lack of unit tests can be a little off-putting, but again, it's a small library solving a problem with limited scope. The code is short and clear enough to read and convince yourself of its correctness.</p> |

Or any suggestion to create just 'Users' table and work with it?</p> <p>Many thanks in advice.</p> |
14,380,143 | 0 | Matching binary patterns in C <p>I'm currently developing a C program that needs to parse some bespoke data structures, fortunately I know how they are structured, however I'm not sure of how to implement my parser in C.</p> <p>Each of the structures are 32-bits in length, and each structure can be identified by it's binary signature.</p> <p>As an example, there are two particular structures that I'm interested in, and they have the following binary patterns (x means either 0 or 1)</p> <pre><code> 0000-00xx-xxxx-xxx0 0000-10xx-10xx-xxx0 </code></pre> <p>Within these structures the 'x' bits contain the actual data I need, so essentially I need a way of identifying each structure based on how the bits are written within each structure.</p> <p>So as an example in pseudo-code:</p> <pre><code>if (binaryPattern = 000010xxxxxxxxx0) { do something with it; } </code></pre> <p>I'm guessing that reading them as ints, and then performing some kind of bitmasking would be the way to go, but my knowledge of C isn't great, and maybe a simple logical OR operation would do it, but I just wanted some advice on doing this before I start.</p> <p>Thanks</p> <p>Thanks very much to everyone that has answered, very helpful!!</p> |

20,434,378 | 0 | <p>I disagree with the previous post. This is not a threading issue, this is an algorithm issue. The reason matlab, R, and octave wipe the floor with C++ libraries is because their C++ libraries use more complex, better algorithms. If you read the octave page you can find out what <em>they</em> do[1]: </p> <blockquote> <p>Eigenvalues are computed in a several step process which begins with a Hessenberg decomposition, followed by a Schur decomposition, from which the eigenvalues are apparent. The eigenvectors, when desired, are computed by further manipulations of the Schur decomposition.</p> </blockquote> <p>Solving eigenvalue/eigenvector problems is non-trivial. In fact its one of the few things "Numerical Recipes in C" recommends you <em>don't</em> implement yourself. (p461). GSL is often slow, which was my initial response.

Two possible issues that the compiler will complain about:</p> <ul> <li>there is no proof that the node will not move, so the reference you take might be invalidated</li> <li>there is no proof that the node will not be mutated, so having two aliases to it (and being able to hand over two aliases to it) create a safety hole</li> </ul> <hr> <p>Now what?</p> <p>There are various approaches. If you are sure of yourself you could use <code>unsafe</code> and raw pointers, for example. However, the simpler solutions would be:</p> <ul> <li>use a <code>Vec</code> to store the nodes, and indexes to link them</li> <li>use <code>Rc</code> and <code>Weak</code></li> </ul> <p>The former is:</p> <pre><code>struct Node<T> { data: T, next: Option<usize>, random: Option<usize>, } pub struct List<T> { store: Vec<Node<T>>, } </code></pre> <p>And the latter would be:</p> <pre><code>struct Node<T> { data: T, next: Option<Rc<Node<T>>, random: Option<Weak<Node<T>>, } pub struct List<T> { head: Option<Rc<Node<T>>, } </code></pre> <p>the latter however will not allow mutation of the internal nodes (because there is inherent aliasing) so you may need to wrap the <code>T</code> into <code>RefCell<T></code>.</p> |

5,530,499 | 0 | <p>Singular is a computer algebra system. Haskell is a programming language which computer algebra can be implemented within. You need to start simply and just learn basic Haskell syntax and concepts before trying to see the categorical/algebriac picture, especially since different elements can be implemented in different ways.</p> <p>But let's try something simple to establish a common language. The notes I give here should be consistent with the treatment here: <a href="http://en.wikibooks.org/wiki/Haskell/Category_theory" rel="nofollow">http://en.wikibooks.org/wiki/Haskell/Category_theory</a></p> <p>One approach is to describe the category <code>Hask</code>. The objects of <code>Hask</code> are all Haskell types. <code>Hask</code> contains function types, as well as pairs, so it is cartesian closed, and all its arrows are isomorphic to objects. In categorical terms, a hom-set is the collection of all morphisms between two objects. So the hom-set on (Int,Float) is the collection of all functions that turn an Int into a Float. </p> <p>Categorically, a functor between categories X and Y sends the objects of X to Y and the arrows of X to Y. It also therefore sends the hom-sets (collections of arrows) of X to Y.</p> <p>The class <code>Functor</code> in Haskell provides part of what you get with a categorical functor. It provides an operation <code>fmap</code> that sends arrows on objects in <code>Hask</code> to arrows on some other category (which, in our case, must also be composed of <em>some</em> objects from Hask). It can send functions on values to functions on lists of values, or functions on values to functions on pairs which contain values, etc.</p> <p>All that said, I would recommend learning Haskell without thinking about writing type classes or instances at all for some time. Stick to explicit data declarations and functions until you're more comfortable with the basic features of the language.</p> |

5,633,371 | 0 | Using a gitosis git repository with XCode 4 <p>Hi I've been trying to access my git repository from XCode 4.</p> <p>Everything works just fine using the command line tools. I can clone my repo using:</p> <pre><code>git clone [email protected]:somerepo.git </code></pre> <p>But in XCode, when trying to use:</p> <pre><code>ssh://[email protected]:somerepo.git </code></pre> <p>It just keeps asking me for a password, which I don't want to use at all.</p> <p>The same thing happens with:</p> <pre><code>git://[email protected]:somerepo.git </code></pre> <p>Except that i also get a "Connection refused: unable to connect to a socket" error message.</p> <p>Any idea how to solve this?</p> |
13,892,367 | 0 | <p>You can change the log in the y axis with the following:</p> <pre><code>plt.gca().set_yscale('linear') </code></pre> <p>Or press the L key when the figure is in focus.</p> <p>However, your <code>hist()</code> with <code>log=True</code> does not plot a logarithmic x axis. From the <a href="http://matplotlib.org/api/pyplot_api.html#matplotlib.pyplot.hist" rel="nofollow">docs</a>:</p> <blockquote> <p>matplotlib.pyplot.hist(x, bins=10, ...)</p> <p>bins: Either an integer number of bins or a sequence giving the bins. If bins is an integer, bins + 1 bin edges will be returned, consistent with numpy.histogram() for numpy version >= 1.3, and with the new = True argument in earlier versions. <strong>Unequally spaced bins are supported if bins is a sequence.</strong></p> </blockquote> <p>So if you just set <code>bins=10</code> they will be equally spaced, which is why when you set the xscale to log they have decreasing widths. To get equally spaced bins in a log xscale you need something like:</p> <pre><code>plt.hist(x, bins=10**np.linspace(0, 1, 10)) </code></pre> |
