38,705,646 | 0 | Can a pure function return a Symbol? <p>This may border on philosophical, but I thought it would be the right place to ask.</p> <p>Suppose I have a function that creates a list of IDs. These identifiers are only used internally to the application, so it is acceptable to use ES2015 <code>Symbol()</code> here.</p> <p>My problem is that, <em>technically</em>, when you ask for a Symbol, I'd imagine the JS runtime creates a unique identifier (random number? memory address? unsure) which, to prevent collisions, would require accessing global state. The reason I'm unsure is because of that word, "technically". I'm not sure (again, from a philosophical standpoint) if this ought to be enough to break the mathematical abstraction that the API presents.</p> <p><strong>tl;dr:</strong> here's an example--</p> <pre><code>function sentinelToSymbol(x) { if (x === -1) return Symbol(); return x; } </code></pre> <p><em>Is this function pure?</em></p> |

24,278,474 | 0 | containsKey check for hashmap <p>I have read multiple posts to understand this, but I can't seem to quite get in on why we do a check if a map does not contain a key before performing a put operation? For eg,</p> <pre><code> if(!myMap.containsKey(myKey) { myMap.put(myKey,myValue); } </code></pre> <p>Why do we need this check? Either way, map doesn't allow duplicate key, and replaces the key with the new value if the key already exists. So why do we need to check this explicitly? Is this check needed for all implementations of Map? I am sorry if this is a very basic question. I can't seem to find an answer to this exact question. If there are posts that answer this that I may have missed, please point me to them, and feel free to mark mine as duplicate.</p> |

26,835,497 | 0 | <p>If you want to assign the result to a <code>List(Of String)</code> variable then you need a <code>List(Of String)</code> object. You can all <code>ToList</code> on any enumerable list to create a <code>List(Of T)</code>.</p> <p>Also, your <code>AsEnumerable</code> call is pointless because <code>Cast(Of T)</code> already returns an <code>IEnumerable(Of T)</code>.</p> <p>Finally, declaring a variable on one line and then setting its value is so unnecessarily verbose. It's not wrong but it is pointless. In your case, not only are you declaring a variable but you're also creating an object that you never use. Don't create a <code>New</code> object if you don;t actually want a new object, which you don;t because you're getting an object on the very next line.</p> <pre><code>Dim list As List(Of String) = chkparameter.Items. Cast(Of ListItem). Where(Function(x) x.Selected). Select(Function(x) x.Value). ToList() </code></pre> <p>There's also no need to declare the type of the variable because it will be inferred from the initialising expression, i.e. <code>ToList</code> returns a <code>List(Of String)</code> so the type of the variable can be inferred from that. Not everyone likes to use type inference where it's not completely obvious though, so I'll let you off that one. I'd tend to do this though:</p> <pre><code>Dim list = chkparameter.Items. Cast(Of ListItem). Where(Function(x) x.Selected). Select(Function(x) x.Value). ToList() </code></pre> <p>By the way, notice how much easier the code is to read with some sensible formatting? If you're going to use chained function syntax like that, it's a very good idea to put each function on a different line once you get more than two or three.</p> |

38,750,310 | 0 | Having selected data from one datagrid be displayed on another datagrid <p>I am trying to select one customer from a datagrid and then have that customers name be displayed in a list of customers that are being seen that day </p> <p>Here is the XAML:</p> <pre><code><Grid Name="gridListOfAllCustomers" Visibility="Collapsed" Margin="235,26,-740,56" Grid.Row="3" Grid.RowSpan="4" Grid.Column="1"> <DataGrid Name="dataGridListOfAllCustomers" IsReadOnly="True" AutoGenerateColumns="False" ItemsSource="{Binding Customer}" SelectionChanged="dataGridListOfAllCustomers_SelectionChanged"> <DataGrid.Columns> <DataGridTextColumn Header="Customer User Name" Binding="{Binding UserName}" Width="*"/> <DataGridTextColumn Header="First Name" Binding="{Binding FirstName}" Width="*"/> <DataGridTextColumn Header="Last Name" Binding="{Binding LastName}" Width="*"/> <DataGridTextColumn Header="Birthday" Binding="{Binding Birthday, StringFormat=\{0:dd/MM/yyyy\}}" Width="*"/> </DataGrid.Columns> </DataGrid> </Grid> </code></pre> <p>^ That grid is the one I am selecting data from</p> <pre><code><Grid Name="gridCustomersOfTheDay" Visibility="Collapsed" Margin="10,2,2,42" Grid.Row="4" Grid.RowSpan="4" Grid.ColumnSpan="2"> <Grid.RowDefinitions> <RowDefinition Height="7*"/> <RowDefinition Height="1*"/> <RowDefinition Height="1*"/> </Grid.RowDefinitions> <DataGrid Name="dataGridCustomersToday" IsReadOnly="True" AutoGenerateColumns="True" Grid.Row="0" AutoGeneratingColumn="dataGridCustomersToday_AutoGeneratingColumn"/> <Button Name="btnEditCustomersToday" Content="Edit List" Grid.Row="1"/> <Button Name="btnClearCustomers" Content="Clear List" Grid.Row="2" Click="btnClearCustomers_Click"/> </Grid> </code></pre> <p>^ That Grid should display the data</p> <p>This is what happens when I click the button for todays Customers</p> <pre><code>private void btnCustomersToday_Click(object sender, RoutedEventArgs e) { if (btnCustomersToday.IsChecked == true) { dataGridListOfAllCustomers.Visibility = System.Windows.Visibility.Visible; dataGridCustomersToday.Visibility = System.Windows.Visibility.Visible; } else { dataGridListOfAllCustomers.Visibility = System.Windows.Visibility.Collapse; dataGridCustomersToday.Visibility = System.Windows.Visibility.Collapse; } ResponseBase<List<CustomerInfo>> allCustomers = Data.DataManager.GetCustomerList(""); List<CustomerInfo> listOfAllCustomers = allCustomers.Data; dataGridListOfAllCustomers.ItemsSource = listOfAllCustomers; //Field dataGridCustomersToday.ItemsSource = displayWorkList; //Field } </code></pre> <p>And lastly this is for the selection change</p> <pre><code>private void dataGridListOfAllCustomers_SelectionChanged(object sender, SelectionChangedEventArgs e) { CustomerInfo CustomerForTodayList = (CustomerInfo) dataGridListOfAllCustomers.SelectedItem; if (e.AddedItems.Count == 0) { return; } currentCustomersToday.Add(CustomerForTodayList.UserName); String customerID = CustomerForTodayList.UserName; StringValue addCustomer = new StringValue(customerID); displayWorkList.Add(addCustomer); } </code></pre> <p>So the issue is I click the customer and I have to change the visibility of the second datagrid in order for User name of the customer to appear. Also there is a lag on the second customer for some reason. As in when I select the second customer I also need to select a third customer in order for them to appear (I still need to click). </p> <p>I don't even know what could be possible solutions because my understanding of databinding and datagrids is so limited. I have tried reading the documentation and reading tutorials but no one thoroughly explains path and sources as well as how to make a collections and so. </p> |

18,760,926 | 0 | <p>With Core Bluetooth background communication must be implemented either with characteristic change notifications or indications. You are keeping the app running for too long after being brought to background and iOS is killing it forcefully. I suppose you are using the <code>beginBackgroundTaskWithExpirationHandler:</code> method to keep some timers running. This doesn't work for long periods of time. The limit is around 10 minutes but it may depend on other factors too.</p> <p>The <a href="https://developer.apple.com/library/ios/documentation/NetworkingInternetWeb/Conceptual/CoreBluetooth_concepts/CoreBluetoothBackgroundProcessingForIOSApps/PerformingTasksWhileYourAppIsInTheBackground.html#//apple_ref/doc/uid/TP40013257-CH7-SW1" rel="nofollow">Core Bluetooth Programming Guide</a> contains a pretty concise description of how backgrounding has to be handled. Practically, your app needs to subscribe on either notifications or indications of the heart rate characteristic and react to it only when the callbacks happen.

Then you can remove the redundant eof test at the end.</p> <p>It's still open even if you've encountered an error or reached the end of file. It's likely you are in a scenario where failbit is getting set (getline returns nothing), but eof has not been encountered, so the file never gets closed, so your loop never exits. Using the <code>operator bool</code> of the stream gets around all these problems for you.</p> |

11,655,212 | 0 | <p>I think the confusion comes from the idea of normalizing "a value" as opposed to "a vector"; if you just think of a single number as a value, normalization doesn't make any sense. Normalization is only useful when applied to a vector.</p> <p>A vector is a sequence of numbers; in 3D graphics it is usually a coordinate expressed as <code>v = <x,y,z></code>.</p> <p>Every vector has a <em>magnitude</em> or <em>length</em>, which can be found using Pythagora's theorem: <code>|v| = sqrt(x^2 + y^2 + z^2)</code> This is basically the length of a line from the origin <code><0,0,0></code> to the point expressed by the vector.</p> <p>A vector is <em>normal</em> if its length is 1. That's it!</p> <p>To normalize a vector means to change it so that it points in the same direction (think of that line from the origin) but its length is one.</p> <p>The main reason we use normal vectors is to represent a direction; for example, if you are modeling a light source that is an infinite distance away, you can't give precise coordinates for it. But you can indicate where to find it from a particular point by using a normal vector.</p> |

The number of times it has expired will then be stored in the buffer that you're <code>read</code>ing into, or if it hasn't expired, the <code>read</code> will fail with the error EAGAIN.</p> <pre><code>// set up timer // ... uint64_t expirations; if ((read(timer_fd, &expirations, sizeof(uint64_t))==-1) && errno == EAGAIN) { printf("Timer has not expired yet.\n"); } else { printf("Timer has expired %llu times.\n", expirations); } </code></pre> <p>Note that you'll need to initialize <code>timer_fd</code> with the flag <code>TFD_NONBLOCK</code>, or else the <code>read</code> will block if it hasn't expired yet rather than fail, but you already do that.</p> |

19,768,210 | 0 | <p>Since no one else has taken a stab at it, I'll present my understanding of the problem (disclaimer: I'm not an expert on reinforced learning and I'm posting this as an answer because it's too long to be a comment)</p> <p>Think of it this way: when starting at, for example, node d, a random walker has a 50% chance to jump to either node e or node a. Each such jump reduces the reward (r) with the multiplier y (gamma in the picture). You continue jumping around until you get to the target node (f in this case), after which you collect the reward r.</p> <p>If I've understood correctly, the two smaller 3x2 squares represent the expected values of reward when starting from each node. Now, it's obvious why in the first 3x2 square every node has a value of 100: because y = 1, the reward never decreases. You can just keep jumping around until you eventually end up in the reward node, and gather the reward of r=100.</p> <p>However, in the second 3x2 square, with every jump the reward is decreased with a multiplier of 0.9. So, to get the expected value of reward when starting from square c, you sum together the reward you get from different paths, multiplied by their probabilities. Going from c to f has a chance of 50% and it's 1 jump, so you get r = 0.5*0.9^0*100 = 50. Then there's the path c-b-e-f: 0.5*(1/3)*(1/3)*0.9^2*100 = 4.5. Then there's c-b-c-f: 0.9^2*0.5^2*(1/3)^1*100 = 6.75. You keep going this way until the reward from the path you're examining is insignificantly small, and sum together the rewards from all the paths. This should give you the result of the corresponding node, that is, 50+6.75+4.5+... = 76.</p> <p>I guess the programmatic way of doing to would be to use a modified dfs/bfs to explore all the paths of length N or less, and sum together the rewards from those paths (N chosen so that 0.9^N is small).</p> <p>Again, take this with a grain of salt; I'm not an expert on reinforced learning.</p> |

22,798,966 | 0 | <p>Right. Actually, you don't use xml for functions (that would be torture). You put your xml layouts in the <code>/layout</code> folder and then refer to elements to do stuff (like add listeners/whatnot) by doing something like <code>Button yourButton = (Button) <Activity instance>.findViewByID(R.id.your_button)</code>. </p> <p>See: <a href="http://developer.android.com/guide/topics/ui/declaring-layout.html" rel="nofollow">http://developer.android.com/guide/topics/ui/declaring-layout.html</a></p> <p>And if you really don't like xml, you can just do everything in java...</p> |

6,576,640 | 0 | <p>First off, there's lots of different home screen implementations on Android. The stock Android one, Samsung, HTC and Motorola all have their own variants, then third party ones like Launcher Pro. All use different stores as to what to keep on the home screen, may provide different profiles for the home screen (home, work, etc).</p> <p>Second, the home screen is prime real estate. And it is also the user's real estate. If there was programmatic access to the home screen, what happened to the Windows quick launch, desktop, favorites menu (in older versions of IE), and older pin area of the start menu (the very top of it in Win 95/98).</p> <p>To quote Raymond Chen <a href="http://blogs.msdn.com/b/oldnewthing/archive/2006/11/01/922449.aspx" rel="nofollow">"I bet somebody got a really nice bonus for that feature"</a>. So, in short, even if it was possible, please don't. As awesome as you think your program is, the user might not think the same.</p> |
39,432,927 | 0 | annotation information lost in scala 2.12 trait <p>Just updated a scala 2.11 + JavaFX project to 2.12.0-RC1, the code use java <code>@FXML</code> annotation intensively, e.g.</p> <pre><code>trait MainController { @FXML def onRun(event: ActionEvent) { val script = currentEngine.executeScript("editor.getValue()").toString runScript(script) } } <MenuItem mnemonicParsing="false" onAction="#onRun" text="Run"> <accelerator> <KeyCodeCombination alt="UP" code="R" control="UP" meta="UP" shift="UP" shortcut="DOWN"/> </accelerator> </MenuItem> </code></pre> <p>At runtime it throws error while executing <code>FXMLLoader.load</code>: </p> <pre><code>javafx.fxml.LoadException: Error resolving onAction='#onRun', either the event handler is not in the Namespace or there is an error in the script. </code></pre> <p>Seems that the <code>@FXML</code> annotation information has been lost during compilation. I have heard that in 2.12 all traits are compiled to interfaces, but how does this change cause the problem? Is there any workaround?</p> |
