4,189,778 | 0 | <p>The CLR makes no guarantees with respect to the order that finalizers will be called. It sees a group of unrooted objects (e.g. not reachable from any GC root) and starts calling finalizers. It doesn't matter that you have connections within your object graph. The finalizers can be called in any order. Finalizers are intended to clean up unmanaged resources, not child objects. You need to re-think your API.</p> |
6,780,483 | 0 | <p>As a lot of people have suggested, Resource Leaks are fairly easy to cause - like the JDBC examples. Actual Memory leaks are a bit harder - especially if you aren't relying on broken bits of the JVM to do it for you...</p> <p>The ideas of creating objects that have a very large footprint and then not being able to access them aren't real memory leaks either. If nothing can access it then it will be garbage collected, and if something can access it then it's not a leak...</p> <p>One way that <em>used</em> to work though - and I don't know if it still does - is to have a three-deep circular chain. As in Object A has a reference to Object B, Object B has a reference to Object C and Object C has a reference to Object A. The GC was clever enough to know that a two deep chain - as in A <--> B - can safely be collected if A and B aren't accessible by anything else, but couldn't handle the three-way chain...</p> |

14,954,554 | 0 | <p>Probably reason of those twitches is endless loop. When your <code>p:selectCheckboxMenu</code> is shown remote command is called, and <code>p:selectCheckboxMenu</code> is updated and it is shown again and remote command is called again... And this never ends. It is strange that you are updating component in <code>onShow</code>. You probably should do this in moment when conditions for updating are changed, this is not place where you should update component. If this <code>p:selectCheckboxMenu</code> is for example dependent on some <code>p:selectOneMenu</code> update it when value of <code>p:selectOneMenu</code> is changed.</p> |

8,203,330 | 0 | <p>First off, "compiler" does <strong>not</strong> imply "outputs machine code". You can compile from any language to any other, be it a high-level programming language, some intermediate format, code for a virtual machine (bytecode) or code for a physical machine (machine code).</p> <ol> <li><p>Like a compiler, an interpreter needs to read and understand the language it implements. Thus you have the same front-end code (though today's interpreters usually implement far simpler language - the bytecode only; therefore these interpreters only need a very simple frontend). Unlike a compiler, an interpreter's backend doesn't generate code, but executes it. Obviously, this is a different problem entirely and hence an interpreter looks quite difference from a compiler. It emulates a computer (often one that's far more high-level than real life machines) instead of producing a representation of an equivalent program.</p></li> <li><p>Assuming today's somewhat-high-level virtual machines, this is the job of the interpreter - there are dedicated instructions for, among other things, calling functions and creating objects, and garbage collection is baked into the VM. When you target lower-level machines (such as the x86 instruction set), many such details need to be baked into the generated code, be it directly (system calls or whatever) or via calling into the C standard library implementation.</p></li> </ol> <p>3.</p> <ul> <li><p>a) Probably not, as a VM dedicated to Python won't require it. It would be very easy to screw up, unnecessary and arguably incompatible to Python semantics as it allows manual memory management. On the other hand, if you were to target something low-level like LLVM, you'd have to take special care - the details depend on the target language. That's part of why nobody does it.</p></li> <li><p>b) It would be a perfectly fine compiler, and obviously not an interpreter. You'd probably have a simpler backend than a compiler targeting machine code, and due to the nature of the input language you wouldn't have quite as much analysis and optimization to do, but there's no fundamental difference.</p></li> </ul> |

7,204,651 | 0 | <p>There are two approaches:</p> <p>1. Encapsulated timeout</p> <p>The thread reading the data from network or serial port can measure time elapsed from its time of start and wait for the data for no more than the remaining time. Network communication APIs usually provide means to specify a timeout for the operation. Hence by doing simple DateTime arithmetic you can encapsulate timeout management within your worker thread.</p> <p>2. External timeout</p> <p>Use another thread (or do it in the main thread if that's feasible) to wait for the worker thread to finish within a certain time limit, and if not, abort it. Like this:</p> <pre><code>// start the worker thread ... // give it no more than 5 seconds to execute if (!workerThread.Join(new TimeSpan(0, 0, 5))) { workerThread.Abort(); } </code></pre> |

24,376,379 | 0 | <p>I'm not sure about your approach or why there are performance issues but here is my solution to similar issue.</p> <p>The full solution can be found <a href="https://github.com/steinborge/ProxyTypeHelper/wiki" rel="nofollow">https://github.com/steinborge/ProxyTypeHelper/wiki</a></p> <p>What I wanted to achieve was the ability to create a 'generic' view model which can then be assigned to a datatemplate. The data template is just a user control. In the case where you have a lot of simple data maintenance screens would save a lot of repetitive code. </p> <p>But had a couple of issues. Datatemplates don't work well with in XAML with generics and if you have a lot of data templates you are creating a lot of XAML - especially if you wanted to use it in separate views. In your case you mention up to 90 views - this would be a lot of XAML.</p> <p>Solution is to store the templates in a lookup and use a content control and DataTemplateSelector populate depending upon the DataContext. So first need to register the data template/views:</p> <pre><code> manager.RegisterDataTemplate(typeof(GenericViewModel<CarType, WPFEventInter.ViewModel.CarTypeViewModel>), typeof(WPFEventInter.UserControls.CarTypesView)); manager.RegisterDataTemplate(typeof(GenericViewModel<Colour, WPFEventInter.ViewModel.ColourViewModel>), typeof(WPFEventInter.UserControls.ColourView)); </code></pre> <p>RegisterDataTemplate just adds the datatemplate to a dictionary:</p> <pre><code> public void RegisterDataTemplate(Type viewModelType, Type dataTemplateType, string Tag="") { var template = BuildDataTemplate(viewModelType, dataTemplateType) ; templates.Add(viewModelType.ToString() + Tag, template); } private DataTemplate BuildDataTemplate(Type viewModelType, Type viewType) { var template = new DataTemplate() { DataType = viewModelType, VisualTree = new FrameworkElementFactory(viewType) }; return template; } </code></pre> <p>Now create a view with a ContentPresenter control .This will display the view depending upon the view's Datacontext. </p> <p>The DataTemplateSelector looks like the following. This returns the appropriate view depending upon the datacontext:</p> <pre><code>public class ContentControlGenericTemplateSelector : DataTemplateSelector { public override DataTemplate SelectTemplate(object item, DependencyObject container) { DataTemplate retVal = null; try { retVal = Core.WPF.Infrastructure.DataTemplateManager.templates[item.GetType().ToString()]; } catch //empty catch to prevent design time errors.. { } return retVal; } </code></pre> |
38,230,493 | 0 | <p>If there is a field that can be used which can indicate which table that file's data is intended for, you can do something like this using multiple <code>INFILE</code> satements. Let's say the first field is that indicator and it will not be loaded (define it as a FILLER so sqlldr will ignore it):</p> <pre><code>... INTO TABLE table1 WHEN (01) = 'TBL1' fields terminated by ',' optionally enclosed by '"' TRAILING NULLCOLS ( rec_skip filler POSITION(1), Col1 "TRIM(:Col1)", Col2 "TRIM(:Col2)" ) INTO TABLE table2 WHEN (01) = 'TBL2' fields terminated by ',' optionally enclosed by '"' TRAILING NULLCOLS ( rec_skip filler POSITION(1), Colx "TRIM(:Colx)", Coly "TRIM(:Coly)" ) INTO TABLE table3 WHEN (01) = 'TBL3' fields terminated by ',' optionally enclosed by '"' TRAILING NULLCOLS ( rec_skip filler POSITION(1), Colp "TRIM(:Colp)", Colq "TRIM(:Colq)" ) </code></pre> <p>So logically, each INTO table WHEN section handles each file. Not that flexible though and arguably harder to maintain. For ease of maintenance you may just want to have a control file for each file? If all files and tables are the same layout you could also load them all into the same staging table (with the indicator) for ease of loading, then split them out programatically into the separate tables afterwards. Pros of that method are faster and easier loading and more control over the splitting into the separate table part of the process. Just some other ideas. I have done each method, depends on the requirements and what you are able to change.</p> |

Some (many?) will find the new syntax less understandable, though.</p> <pre><code>QString Product::toString() { QStringList aggregate; std::transform(m_transactions.begin(), m_transactions.end(), std::back_inserter(aggregate), std::bind(std::mem_fn(&Transactions::toString), std::placeholders::_1)); // or : [](const Transaction& transaction){ return transaction.toString(); }); return aggregate.join("\n"); } </code></pre> <p><code>std::transform</code> will transform every <code>m_transactions</code> elements using <code>Transaction::toString()</code>, and place the results into <code>aggregate</code>. </p> <p><code>std::back_inserter</code> means "use <code>QStringList::push_bask</code> to record the results". If <code>QStringList</code> had a <code>resize(int)</code> like <code>QVector</code> does, we could have used <code>aggregate.begin()</code> instead.</p> <p>The unary function is a bit tricky, as it needs to be converted into a unary function, which what <code>std::bind</code>/<code>std::mem_fn</code> is doing. If you are using C++11, you can use a lambda instead.</p> <hr> <p>Also from the previous question, @SingerOfTheFall's remark is valid:</p> <blockquote> <p>I also find it a little odd to save transactions inside of products. A better design would be having a separate class that could store them.</p> </blockquote> <p>If you keep this design, <code>Transaction Product::at(int)</code> and <code>int Product::size()</code> should be renamed to make the link with <code>Transaction</code> explicit, like <code>getTransaction</code> and <code>getNumberOfTransactions</code>.</p> |

But level 3 needs 200 and 400 EXP inclusive. If your player has 200EXP he is technically level 2 and 3.

If it wasn't intended you should change it to:</p> <pre><code>if($playerEXPERIENCE >= 100 && $playerEXPERIENCE < 200) </code></pre> <p>Notice the use of <strong><</strong> [LESS THAN] instead of <strong><=</strong> [LESS THAN OR EQUAL TO].</p> <p>I hope this solves your problem :)</p> |

23,175,753 | 0 | <p><strong>Here's How It Works</strong></p> <p>You <strong>>>></strong> Forwarding Aggregator <strong>>>></strong> SMS Aggregator <strong>>>></strong> Mobile Operator <strong>>>></strong> Mobile Company <strong>>>></strong> Your Customer</p> <p><strong>3 Major Parties Are Involved in the Whole Process:</strong></p> <p><strong>1. Mobile Operators:</strong> They Manage SMSC (Short Message Service Centers). AT&T, Sprint/NEXTEL, T-Mobile USA, U.S.Cellular and Verizon Wireless are few of the major mobile operators in the whole world. They have deep connections with all major mobile phone companies. Most of them have 800 to 950 telecommunication/mobile companies in their pannel. All of your messages came to them via SMS Aggregators and they forward them to reciever's Mobile Company which send it to receiver in the end. </p> <p><strong>Cost of becoming a Mobile Operator:</strong> Billion Dollar Business if not Trillion.</p> <p><strong>2. SMS Aggregators:</strong> mBlox, air2web and motricity are few of them. They have deep connections with Mobile operators.</p> <p><strong>Cost of becoming SMS Aggregator:</strong> in Millions</p> <p><strong>3. Forwarding Aggregators/SMS Gateways:</strong> Clickatell, Twilio and esendex and few others are providing SMS Gateway APIs and most of the developers are using Clickatell to integrate its SMS API with their app. They charge different rates for different countries (NO FIXED RATE FOR ALL COUNTRIES). It would cost you rougly around $600-$700 for 100,000 messages (internationally). </p> <p><strong>Cost of becoming Forwarding Aggregator</strong>: May be in Millions</p> <p><strong>Bottom Line:</strong> I'm working on a FREE solution but till today there are no FREE reliable solution in the whole world to send Bulk Messages for FREE internationally. So stop wasting your time on searching for a FREE solution. You have to come up with a new technology in order to achive this.</p> <p>Though there are many options to send Bulk messages within your country for FREE or by spending little money but you simply can't achieve this if you're planning to send messages internationally. </p> <p>Usually I avoid adding comments in any forum but this man really forced me to put my legs in.

13,642,262 | 0 | <p>A U-matrix is a visual representation of the distances between neurons in the input data dimension space. Namely you calculate the distance between adjacent neurons, using their trained vector. If your input dimension was 4 then each neuron in the trained map corresponds to a 4-dimensional vector. Lets say you have a 3x3 hexagonal map.</p> <p><img src="https://i.stack.imgur.com/XIztZ.png" alt="map lattice"></p> <p>The umatrix will be a 5x5 matrix with interpolated elements for each connection between two neurons like this</p> <p><img src="https://i.stack.imgur.com/8pHtC.png" alt="u-mat lattice"></p> <p>The {x,y} elements are the distance between neuron x and y and the values in {x} elements are the mean of the surrounding values. eg {4,5} = distance(4,5) and {4} = mean({1,4},{2,4},{4,5},{4,7}). For the calculation of the distance you use the trained 4-dimensional vector of each neuron and the distance formula that you used for the training of the map (usually Euclidian distance). So the values of the umat are only numbers (no vectors). Then you can assign a light gray colour to the largest of these values and a dark gray to the smallest and the other values to corresponding shades of gray. You can use these colours to paint the cells of the umat and have a visualized representation of the distances between neurons.</p> <p><a href="http://users.ics.aalto.fi/jhollmen/dippa/node24.html" rel="nofollow noreferrer">check also this</a></p> |

You may see it less in the WinForms side of things, because it's harder to just let the container wire everything together when you are designing forms in Visual Studio, but I can say that for server-side .NET applications, where I work at least, IoC is used very successfully.</p> <p>Why use it in .NET? For the same reason you use it everywhere else. The 2 biggest things I like are:</p> <ul> <li>Designing for IoC tends to enforce good coding practice - designing to interfaces, low coupling, high cohesion. This also leads to classes that are very easy to unit-test.</li> <li>System configuration can often be changed without recompiling.</li> </ul> <p>Some other posts discussing the different IoC/DI frameworks available for .NET:</p> <ul> <li><a href="http://stackoverflow.com/questions/21288/which-cnet-dependency-injection-frameworks-are-worth-looking-into">Which C#/.net Dependency Injection frameworks are worth looking into?</a></li> <li><a href="http://stackoverflow.com/questions/148908/which-dependency-injection-tool-should-i-use">Which Dependency Injection Tool Should I Use?</a></li> </ul> |
