31,289,958 | 0 | auto fix errors when removing a user control property <p>When I remove a user control property that I have created and used in a project. There will be as many errors as times I have used control in project. For example imagine I have user control and it has a property named <code>p1</code>. when I remove <code>p1</code> I get errors saying myusercontrol.p1 doesn't exist. </p> <p>Is there a way to get rid of them automatically?</p> |
35,638,617 | 0 | <p>You code is not formatted with indents, so this may be wrong.</p> <p>I suspect your indentation results in <code>if j in screen:</code> running after the <code>for j...</code> loop, not in it. Also, read the definition of <code>pass</code>.</p> |
36,789,589 | 0 | <p>As far as I understand, you don't need to use <code>Semaphore</code> here. Instead, you should use <code>ReentrantReadWriteLock</code>. Additionally, the <code>test</code> method is not thread safe. </p> <p>The sample below is the implementation of your logic using RWL</p> <pre><code>private ConcurrentMap<String, ReadWriteLock> map = null; void test() { String hash = null; ReadWriteLock rwl = new ReentrantReadWriteLock(false); ReadWriteLock lock = map.putIfAbsent(hash, rwl); if (lock == null) { lock = rwl; } if (lock.writeLock().tryLock()) { try { compute(); map.remove(hash); } finally { lock.writeLock().unlock(); } } else { lock.readLock().lock(); try { compute(); } finally { lock.readLock().unlock(); } } } </code></pre> <p>In this code, the first successful thread would acquire <code>WriteLock</code> while other <code>Thread</code>s would wait for release of write lock. After release of a <code>WriteLock</code> all <code>Thread</code>s waiting for release would proceed concurrently.</p> |

721,811 | 0 | Excel VBA - Initializing Empty User Types and Detecting Nulls <p>I have created a user defined type to contain some data that I will use to populate my form. I am utilizing an array of that user defined type, and I resize that array as I pull data from an off-site server.</p> <p>In order to make my program easier to digest, I have started to split it into subroutines. However, when my program is initialized, I cannot tell when a particular array has been initialized, and so I cannot be certain that I can call a size function to see if the array is empty.</p> <p>Is there a way to initialize an empty user type or detect a null user type? Currently, I am hard-coding it in and I would prefer a more elegant solution.</p> |

Sure, our type system isn't as tight as we want (no type system is), but programmers would instinctively follow the intended constraints, don't go out of their ways to write bizarre stuff just because they can.</p> <p>Ideally, we would want a <code>This</code> type, and our intended constraints can be expressed as</p> <pre><code>interface Item<C extends Container<This>>> interface Container<I extends Item<This>> </code></pre> <p>Since we don't have <code>This</code>, one would attempt to approach it by a type parameter</p> <pre><code>interface Item<C extends Container<This, C>>, This extends Item<C, This> > interface Container<I extends Item<This, I>, This extends Container<I, This>> </code></pre> <p>(or, more symmetrically </p> <pre><code> interface Item<C extends Container<I, C>>, I extends Item<C, I> > interface Container<I extends Item<C, I>, C extends Container<I, C>> </code></pre> <p>)However, this is not really tight either. <code>This</code> isn't really the "this type". It's possible to</p> <pre><code>class HerItem implements Item<MyContainer, MyItem> // uh? </code></pre> <p>Once again, we must rely on programmer's discipline not to do stuff like that.</p> |

If the entire set of data must be examined and returned then there is not going to be any benefit in using yield because all it did was introduce overhead.</p> <p>When yield really shines is when only a partial set is returned. I think the best example is sorting. Assume you have a list of objects containing a date and a dollar amount from this year and you would like to see the first handful (5) records of the year. </p> <p>In order to accomplish this, the list must be sorted ascending by date, and then have the first 5 taken. If this was done without yield, the <em>entire</em> list would have to be sorted, right up to making sure the last two dates were in order.</p> <p>However, with yield, once the first 5 items have been established the sorting stops and the results are available. This can save a large amount of time.</p> |

2,217,431 | 0 | <p>Yes you can create multiple controls in the same project, you simply have to place the all the default templates in a single /themes/generic.xaml file. Each controls template is identified by the <code>TargetType</code>. So your generic.xaml file would look something like:-</p> <pre><code> <ResourceDictionary ... blah namespace stuff ...> <Style TargetType="local:CustomControl1"> <Setter Property="Template"> <Setter.Value> <ControlTemplate TargetType="local:CustomControl1"> <!-- Template for Custom control 1 --> </ControlTemplate> </Setter.Value> </Setter> </Style> <Style TargetType="local:CustomControl2"> <Setter Property="Template"> <Setter.Value> <ControlTemplate TargetType="local:CustomControl2"> <!-- Template for Custom control 2 --> </ControlTemplate> </Setter.Value> </Setter> </Style> <!-- and so on --> </ResourceDictionary> </code></pre> <p>The Silverlight Toolkit chapies do have a neat tool which allows you to place each control template in its own file. The tool dynamically constructs the generic.xaml from the contents of all these files. I really wish they'd blog about it so we could find out how to use it ourselves.

6,195,637 | 0 | <p>Essentially this is a duplicate of <a href="http://stackoverflow.com/questions/2472422/django-file-upload-size-limit">Django File upload size limit</a> </p> <p>You have two options:</p> <ol> <li><p>Use validation in Django to check the uploaded file's size. The problem with this approach is that the file must be uploaded completely before it is validated. This means that if someone uploads a 1TB file, you'll probably run out of hard drive space before the user gets a form error.</p></li> <li><p>Configure the Web server to limit the allowed upload body size. e.g. if using Apache, set the <code>LimitRequestBody</code> setting. This will mean if a user tries to upload too much, they'll get an error page configurable in Apache</p></li> </ol> <p>As @pastylegs says in the comments, using a combination of both is probably the best approach. Say you want a maximum of 5MB, perhaps enforce a 20MB limit at the Web server level, and the 5MB limit at the Django level. The 20MB limit would provide some protection against malicious users, while the 5MB limit in Django provides good UX.</p> |

26,478,442 | 0 | <p>I took a look at the apis in sklearn.svm.* family. All below models, e.g.,</p> <ul> <li>sklearn.svm.SVC</li> <li>sklearn.svm.NuSVC</li> <li>sklearn.svm.SVR</li> <li>sklearn.svm.NuSVR</li> </ul> <p>have a common <a href="http://scikit-learn.org/0.11/modules/generated/sklearn.svm.NuSVR.html" rel="nofollow noreferrer">interface</a> that supplies a </p> <pre><code>probability: boolean, optional (default=False) </code></pre> <p>parameter to the model. If this parameter is set to True, libsvm will train a probability transformation model on top of the SVM's outputs based on idea of <a href="http://citeseerx.ist.psu.edu/viewdoc/summary?doi=10.1.1.41.1639" rel="nofollow noreferrer">Platt Scaling</a>. The form of transformation is similar to a logistic function as you pointed out, however two specific constants <code>A</code> and <code>B</code> are learned in a post-processing step. Also see this <a href="http://stackoverflow.com/questions/15111408/how-does-sklearn-svm-svcs-function-predict-proba-work-internally">stackoverflow</a> post for more details.</p> <p><img src="https://i.stack.imgur.com/LcIQF.png" alt="enter image description here"></p> <p>I actually don't know why this post-processing is not available for LinearSVC. Otherwise, you would just call <code>predict_proba(X)</code> to get the probability estimate. </p> <p>Of course, if you just apply a naive logistic transform, it will not perform as well as a calibrated approach like <a href="http://citeseerx.ist.psu.edu/viewdoc/summary?doi=10.1.1.41.1639" rel="nofollow noreferrer">Platt Scaling</a>. If you can understand the underline algorithm of platt scaling, probably you can write your own or contribute to the scikit-learn svm family. :) Also feel free to use the above four SVM variations that support <code>predict_proba</code>.</p> |
