7,320,133 | 0 | Add alias for jquery support in Eclipse Aptana Plugin <p>I've managed to enable jQuery support using this tutorial <a href="http://stackoverflow.com/questions/4721124/how-to-enable-jquery-support-in-aptana-studio-3">How to enable jQuery support in Aptana Studio 3</a> and using code completion with:</p> <pre><code>$. or $("p").add( ... </code></pre> <p>works. But in my projects I need to use the nonconflict Version. So I added this:</p> <pre><code><aliases> <alias name="$" type="jQuery"/> <alias name="jQuery" type="jQuery"/> </aliases> </code></pre> <p>but this doesn't seem to work. </p> <p>This tutorial <a href="http://wiki.appcelerator.org/display/tis/Using+JavaScript+Libraries" rel="nofollow">http://wiki.appcelerator.org/display/tis/Using+JavaScript+Libraries</a> says</p> <blockquote> <p>Save it to your disk, and then drag it into your project. It does not matter where in the project it sits, so you can create a new folder for files like this if you like.</p> </blockquote> <p>so I added a folder /source/support to fit my structure and add .sdocml files there.... but nothing seems to happen. So I'm not really sure if adding the file actually does something. Tried adding it a couple of times, but this doesn't seem to trigger anything.</p> <p>Any clues? </p> |

Personally, I don't put much stock in this estimation method. From my perspective it attempts to provide a precise estimate in for things that have been shown repeatedly to not be precisely measurable. I much prefer <a href="http://www.mountaingoatsoftware.com/topics/planning-poker" rel="nofollow noreferrer">planning poker</a> or something similar that tries to group things within a similar order of magnitude and provide an estimate based on your previous estimations for similarly sized stories.</p> <p>If you're doing this for a class, simply follow the rules given in the text book and crank out the answer. If you're really intending to try this as a software development estimation method, my advice is to simplify the process rather than make it more complex. I would imagine that members of the International Function Point User Group (yes, there is one), will disagree.</p> |

625,154 | 0 | <p>I think they did that on purpose - views should be independent from controllers. Think of it like this: you should be able to put controllers into a totally different assembly and still have your application work. Your controllers should also be able to work with totally different set of views.</p> <p>The framework is also setup to go to the views folder to fetch appropriate files. You would have to change that behavior yourself if you decide to move the views. Might not be worth the hassle.</p> <p>And finally, if you really want to do it, you should probably look at your project file. There is a DependsUpon element that you can use to make a file go underneath another:</p> <pre><code><Compile Include="Form1.Designer.cs"> <DependentUpon>Form1.cs</DependentUpon> </Compile> </code></pre> |

21,583,536 | 0 | <p>Use Python's classes for this.</p> <p>A simple example. Let's first define a Point data structure that will hold information about a point in cartesian coordinates:</p> <pre><code>class Point(object): """ Define a point at X, Y """ def __init__(self, x=0, y=0): self.x=x self.y=y </code></pre> <p>Now let's define a circle:</p> <pre><code>class Circle(object): def __init__(self, x=0, y=0, radius=1): """ Define a circle centered at X, Y with radius """ self.x=x self.y=y self.radius=radius </code></pre> <p>Now you can declare an instance of each and test if the point is inside the circle:</p> <pre><code>>>> c1=Circle() # default of x=0, y=0, radius=1 >>> p1=Point(5,6) # a point at x=5, y=6 </code></pre> <p>Is that point inside the circle? You can test it:</p> <pre><code>>>> ((p1.x-c1.x)**2 + (p1.y - c1.y)**2)**0.5<c1.radius False </code></pre> <p>That would be a whole lot easier if we did not have to remember the pythagorian theorem for the circle's center and the point. Let's add that basic functionality to the Circle object:</p> <pre><code>class Circle(object): def __init__(self, x=0, y=0, radius=1): self.x=x self.y=y self.radius=radius def point_in(self, p): return ((p.x-self.x)**2 + (p.y - self.y)**2)**0.5<self.radius </code></pre> <p>Now you can use a more logical method:</p> <pre><code>>>> c1.point_in(Point(5,5)) False >>> c1.point_in(Point(.5,.5)) True </code></pre> <p>So what about 'above' or 'below'? I suppose 'above' would mean if a point is outside the circle and <code>Point.y > Circle.y</code>. Add this to the Circle class:</p> <pre><code>def above(self, p): return ((p.x-self.x)**2 + (p.y - self.y)**2)**0.5 > self.radius and p.y>self.y </code></pre> <p>Test it:</p> <pre><code>>>> c1.above(Point(5,5)) True </code></pre> <p>You can extend this concept so that you can test if a circle overlaps another circle or an area of a polygon defined by Points. You can also extend it so that each shape will use the appropriate formula for itself and the other shape. (How do you know if polygons intersect? Now we are talking more complexity! Start <a href="http://stackoverflow.com/a/218081/298607">HERE</a>. If you have OpenGL, you can draw the two polygons offscreen with two additive colors and test for added pixel colors...)</p> <p>Then extend that to what you mean by 'above' and 'below' for triangles squares, rectangles, circles. Your basic definition of shapes other than a circle will require a rotation or just be defined as polygons by their vertices. </p> |
14,984,488 | 0 | <p>That is right: no such class exists in the QtGui module of Qt5. And yes, you have to resort to plain OpenGL calls to handle your textures if you don't want to pull in the widget library.</p> <p>That being said, the current (let's say somewhat non-optimal and inconsistent) situation is recognized and actively being discussed by the Qt developers. See Sean Harmer's <a href="http://lists.qt-project.org/pipermail/development/2012-December/008765.html" rel="nofollow">OpenGL in Qt 5.1 and onwards</a> mail, specifically point 7. But following that thread and having a look at the current dev tree, I doubt it is going to land in 5.1.</p> <hr> <p>Edit: Looking at the other answers and the recent comments I'd like to add regarding options you have with standard Qt 5.0:</p> <p>Is your main goal to:</p> <ol> <li>get some pointer you can pass to <code>glTexImage2D(..., GL_UNSIGNED_BYTE, GL_RGBA, pointer)</code> from your potentially 'weird' formatted QImage? or</li> <li>use some helper class that spares you dealing with <code>glTex*()</code> related functions?</li> </ol> <p>If it is the first and linking the (old) OpenGL module (which is part of Qt 5.0) is an option (and apart from 'esthetically' reasons, I don't see why it would not be), you could use the static <code>QGLWidget::convertToGLFormat(QImage)</code> that Victor was hinting at. If not, then doing something like that function does 'by hand' (along the lines of what Xīcò suggested) should work: basically first calling <code>QImage::convertToFormat(QImage::Format_ARGB32)</code> and then add some platform dependent byte swizzeling and mirroring (see <em>convertToGLFormatHelper(...)</em> in <a href="http://qt.gitorious.org/qt/qt/blobs/4.8/src/opengl/qgl.cpp" rel="nofollow">the source</a>). Although, if you happen to use your own shaders, then doing that on the GPU is way faster.</p> <p>If you want to have both <em>and</em> linking the mentioned OpenGL Qt 5.0 add-on module is an option you might be able to actually use a <code>QGLWidget::bindTexture(...)</code> equivalent even in your QQuickView class:</p> <pre><code>GLuint texID = QGLContext::fromOpenGLContext( this->openglContext())->bindTexture(...) </code></pre> <p>Where <code>this</code> would be a QQuickView*. See the <a href="http://qt-project.org/doc/qt-5.0/qtopengl/qglcontext.html" rel="nofollow">QGLContext help</a>. (Disclaimer: I have not tried that myself.)</p> |

40,348,553 | 0 | <p>Another option, that might be more flexible for future needs, is to use <code>dplyr</code>.

11,744,173 | 0 | <p>The problem to be solved is that you have an input and a series of functions, and you want to apply the functions to the input in order.</p> <p>If the functions are purely state-changing functions, <code>s -> s</code> on an input of type <code>s</code>, then you don't <em>need</em> <code>State</code> to use them. Haskell is very good at chaining together functions like these, e.g. with the standard composition operator <code>.</code>, or something like <code>foldr (.) id</code>, or <code>foldr id</code>.</p> <p>However, if the functions both mutate a state <em>and</em> report some result of doing so, so that you could give them the type <code>s -> (s,a)</code>, then gluing them all together is a bit of a nuisance. You have to unpack the result tuple and pass the new state value to the next function, use the reported value somewhere else, and then unpack <em>that</em> result, and so on. It's easy to pass the wrong state to an input function because you have to name each result and input explicitly to do the unpacking. You end up with something like this:</p> <pre><code>let (res1, s1) = fun1 s0 (res2, s2) = fun2 s1 (res3, s3) = fun3 res1 res2 s1 ... in resN </code></pre> <p>There, I accidentally passed <code>s1</code> instead of <code>s2</code>, maybe because I added the second line in later and didn't realise the third line needed changing. When composing the <code>s -> s</code> functions, this problem can't possibly arise because there are no names to get right:</p> <pre><code>let resN = fun1 . fun2 . fun3 . -- etc. </code></pre> <p>So we invented <code>State</code> to do the same trick. <code>State</code> is essentially just a way of gluing functions like <code>s -> (s,a)</code> together in such a way that the right state always gets passed to the right function.</p> <p>So it's not so much that people went "we want to use <code>State</code>, let's use <code>s -> (s,a)</code>" but rather "we're writing functions like <code>s -> (s,a)</code>, let's invent <code>State</code> to make that easy". With functions <code>s -> s</code>, it's already easy and we don't have to invent anything.</p> <p>As an example of how <code>s -> (s,a)</code> arises naturally, consider parsing: a parser will be given some input, consume some of the input and return a value. In Haskell, this is naturally modelled as taking an input list, and returning a pair of the value and the remaining input - i.e. <code>[Input] -> ([Input], a)</code>, or <code>State [Input]</code>.</p> |

36,682,139 | 0 | <p>One way of doing this is to perform a rolling upgrade. This will ensure that your deployed application incurs no downtime (new pods are started before old pods are stopped). One caveat is that you must be using a replication controller or replication set to do so.
