14,764,304 | 0 | <p>Sounds like precision problems. Movement can amplify the effect of rounding errors. When working on a model of the solar system (uom: meters) in three.js, I ran into many issues with "flickering" textures/models myself. gaitat is absolutely correct that you are experiencing z-buffer depth precision issues. There are a few ways that my partner and I dealt with it.</p> <p>The z-buffer is not linear. sjbaker's site mentioned by gaitat will make that quite clear as it did for me months ago. Most z-buffer precision is found in the near. If your objects are be up to 1000000 units in size, then the objects themselves, not to mention the space between them, are already outside of the range of effective precision. One solution used by many, many video games out there, is to <em>not</em> move the player(camera), but instead move the world. This way, as something gets closer to the camera, it's precision increases. This is most important for textures on large overlapping objects far away (flickering/occlusion), or for small meshes far from the axial origin, where rounding problems become severe enough to jump meshes out of view. It is definitely easier said than done though, as you either have to make a "just in time" calculation to move everything in respect to the player (and still suffer rounding errors) or come up with a more elegant solution.</p> <p>You will lose very little near precision with very high far numbers, but you will gain considerable precision in the mid-range with slightly larger near numbers. Even if the meshes you are working with can be as small as 10 units, a near camera setting of 10 or 100 might buy you some slack. Camera settings are not the only way to deal with the z-buffer.</p> <p><a href="http://www.opengl.org/archives/resources/faq/technical/polygonoffset.htm">polygonOffset</a> - You effectively tell the z-buffer which thing (material on a mesh) belongs on top. It can introduce as many problems as it solves though, and can take quite a bit of tuning. Consider it akin to z-index in css, but a bit more fickle. Increasing the offset on one material to make sure it is rendered over something in the far, may make it render over something in the near. It can snowball, forcing you to set offsets on most of your objects. Factor and unit numbers are usually between -1.0 and 1.0 for polygonOffset, and may have to be fiddled with.</p> <p><a href="http://threejsdoc.appspot.com/doc/three.js/src.source/materials/Material.js.html">depthWrite=false</a> - This means "do not write to the depth-buffer" and is great for a material that should <em>always</em> be rendered "behind" everything. Good examples are skyboxes and backgrounds.</p> <p>Our project used all the above mentioned methods and still had mediocre results, though we were dealing with numbers as large as 40 Astronomical Units in meters (Pluto). </p> <p>"They" call it "z-fighting", so fight the good fight!</p> |

35,005,713 | 0 | <p>You'll need to add a custom import hook. Python added a way to register custom import hooks. Prior to this mechanism, you would have to override the built-in <code>__import__</code> function. But it was particularly error-prone, especially if multiple libraries were both trying to add custom import behavior.</p> <p><a href="https://www.python.org/dev/peps/pep-0302/" rel="nofollow">PEP 0302</a> describes the mechanism in detail.</p> <p>Essentially, you need to create two objects -- a Finder object and a Loader object.</p> <p>The Finder object should define a function called <code>find_module</code> </p> <blockquote> <p>This method will be called with the fully qualified name of the module. If the finder is installed on sys.meta_path , it will receive a second argument, which is None for a top-level module, or <code>package.__path__</code> for submodules or subpackages [5] . It should return a loader object if the module was found, or None if it wasn't.</p> </blockquote> <p>If the <code>find_module</code> function finds the module and returns a Loader object, the Loader object should define a <code>load_module</code> function</p> <blockquote> <p>This method returns the loaded module or raises an exception, preferably ImportError if an existing exception is not being propagated. If load_module() is asked to load a module that it cannot, ImportError is to be raised.</p> </blockquote> <p>Here is a short example detailing how it would work:</p> <pre><code>import sys import imp class CustomImportFinder(object): @staticmethod def find_module(fullname, path=None): # Do your custom stuff here, look in database, etc. code_from_database = "VAR = 1" return CustomImportLoader(fullname, path, code_from_database) class CustomImportLoader(object): def __init__(self, fullname, path, code_from_database): super(CustomImportLoader, self).__init__() self.fullname = fullname self.path = path self.code_from_database = code_from_database def is_package(fullname): # is this a package? return False def load_module(self, fullname): code = self.code_from_database ispkg = self.is_package(fullname) mod = sys.modules.setdefault(fullname, imp.new_module(fullname)) mod.__file__ = "<%s>" % self.__class__.__name__ mod.__loader__ = self if ispkg: mod.__path__ = [] mod.__package__ = fullname else: mod.__package__ = fullname.rpartition('.')[0] exec(code, mod.__dict__) return mod sys.meta_path.append(CustomImportFinder) import blah print(blah) # <module 'blah' (built-in)> print(blah.VAR) # 1 </code></pre> |

It is how you arrive at your package structure.</p> <p>Things like abstraction ("what" instead of "how", essentially "public" API), coupling (the degree of how dependent a package is on other packages) and cohesion (how interrelated is the functionality in one package) are more important.</p> <p>Some guidelines for package design (mostly from <a href="http://butunclebob.com/" rel="nofollow noreferrer">Uncle Bob</a>) are for example:</p> <ul> <li>Packages should form reusable and releasable modules</li> <li>Packages should be focussed for good reusability</li> <li>Avoid cyclic dependencies between packages</li> <li>Packages should depend only on packages that change less often</li> <li>The abstraction of a package should be in proportion to how often it changes</li> </ul> <p>Do not try to flesh out an entire package structure from scratch (You Are Not Going To Need It). Instead let it evolve and refactor often. Look at the <code>import</code> section of your Java sources for inspiration on moving types around.

I have source code for a Linux driver, which I am trying to enhance to add video4linux2 support. My changes are based on the vivi example.</p> <p>The problem I've come up against is that all the example I can find deal with only video or only audio. Even on the client side, everything seems to assume v4l is just video, like ffmpeg's libavdevice.</p> <p>Do I need to have my driver create two separate devices, a v4l2 device and an alsa device? It seems like this makes the job of keeping audio and video in sync much more difficult.</p> <p>I would prefer some way for each buffer passed between the driver and the app (through v4l2's mmap interface) contain a frame, plus some audio that matches up (with respect to time) with that frame.</p> <p>Or perhaps have each buffer contain a flag indicating if it is a video frame, or a chunk of audio. Then the time stamps on the buffers could be used to sync things up.</p> <p>But I don't see a way to do this with the V4L2 API spec, nor do I see any examples of v4l2-enabled apps (gstreamer, ffmpeg, transcode, etc) reading both audio and video from a single device.</p> |

18,685,528 | 1 | Checking for ambiguities in decision tree <p>I'm using sklearn's decision tree to replace a messy and unmantainable implementation of business rules as a long if-elif-else chain. I validate the tree using thousands of test cases for all labels, but sometimes the table with rules I'm using as training data have errors and some tests fail randomly.</p> <p>I need a way to validate the tree, beyond the test cases for the outcomes. Is it correct to assume that if all leaf nodes have a gini = 0.0, there will be no random variation in classification across trees generated with a different random seed? If I need to enforce that on my application, is it reasonable to check for that when updating the training data?</p> <p>Notice that my case is not a typical classification problem, since I already have the decision tree implemented in code, and I want to use an algorithm to generate an equivalent tree from carefully tailored data, rather than a real world data sample, simply because in my case maintaining the data set with business rules is easier than maintaining the code.</p> <p>So, in my data set the features will ideally cover all the possible range of values and give one unambiguous label for that. For instance, while a real world training set might be something like:</p> <pre><code>features = [[1], [1.1], [2], [2.3]] labels = ['sativa', 'sativa', 'indica', 'indica'] </code></pre> <p>And an algorithm can come up randomly with a tree1 like:</p> <pre><code>if feature < 1.75: return 'sativa' else: return 'indica' </code></pre> <p>And a tree2 like:</p> <pre><code>if feature < 1.55: return 'sativa' else: return 'indica' </code></pre> <p>However, my training set wouldn't have the gaps where randomness occurs. It would be like:</p> <pre><code>features = [[1], [1.9], [2], [2.3]] labels = ['sativa', 'sativa', 'indica', 'indica'] </code></pre> <p>So, regardless of the initial random state, the tree would always be (obviously, ignoring differences below 0.1):</p> <pre><code>if feature < 1.95: return 'sativa' else: return 'indica' </code></pre> <p>My problem is precisely that I need to validate if the training set has an error and there's a gap of values where random variation can occur, or if the same set of features is being assigned to different labels. Fixing the random state doesn't solve that problem, it only guarantees the same data will always generate the same tree.</p> <p>So, is there any way to determine if this happens with a tree, other than validating the data for those problems before generating the tree, or running a comprehensive testing a number of times big enough to rule out the random variation?</p> |

1,787,010 | 0 | <p>Well, whether or not there is a better way to extract two tokens than by calling GetToken twice seems irrelevant because one of your requirements is:</p> <blockquote> <p>(the class shall have) a method that subtracts exactly ONE token from your number of tokens</p> </blockquote> <p>So, it seems you are stuck with two calls.

1,383,672 | 0 | <p>If you declare virtual functions you should also declare your destructor virtual ;-).</p> <ol> <li><p>B has a virtual table, because it has a virtual function, namely <code>func0()</code>. If you declare a function (including a destructor) virtual in a base class, all its derived classes will have the function with same signature virtual as well. And it will cause them to have a vtable. Moreover, B would have the vtable even if you didn't declare <code>func0</code> in it explicitly.</p></li> <li><p>Non-virtual functions are not referenced through vtables.</p></li> <li><p>See 2.</p></li> <li><p>No. Classes' vtables are constructed based on class declarations.

You declared your function <code>B::func0()</code> as inline. In <code>gcc</code> compiler, if a virtual function is declared inline, it retains its slot in virtual table, the slot pointing to a special function emitted for that inline one (that counts as taking its address, which makes the inline emitted). That means, whether the funciton is inline doesn't influence amount of slots in vtable and its necessity for a class.</p> |
