4,171,112 | 0 | <p>You seem to be writing a makefile in GNUMake style, but actually running some other version of Make. If it's not obvious what autoreconf is calling, you could insert a rule in the makefile:</p> <pre><code>dummy: @echo using $(MAKE) $(MAKE) -v </code></pre> <p>If this theory proves correct, you can either persuade autoconf to use GNUMake, or write for the version it's using.</p> |

489,674 | 0 | <p>This doesn't sound right. To test it out, I wrote a simple app, that creates a DataTable and adds some data to it. On the button1 click it binds the table to the DataGridView. Then, I added a second button, which when clicked, adds another column to the underlying DataTable. When I tested it, and I clicked the second button, the grid immedialtey reflected the update. To test the reverse, I added a third button which pops up a dialog with a DataGridView that gets bound to the same datatable. At runtime, I then added some values to the first datagridview, and when I clicked the button to bring up the dialog, the changes were reflected.</p> <p>My point is, they are supposed to stay concurrent. Mark may be right when he suggested you check if AutoGenerateColumns is set to true. You don't need to call DataBind though, that's only for a GridView on the web. Maybe you can post of what you're doing, because this SHOULD work.</p> <p>How I tested it:</p> <pre><code> DataTable table = new DataTable(); public Form1() { InitializeComponent(); } private void button1_Click(object sender, EventArgs e) { table.Columns.Add("Name"); table.Columns.Add("Age", typeof(int)); table.Rows.Add("Alex", 26); table.Rows.Add("Jim", 36); table.Rows.Add("Bob", 34); table.Rows.Add("Mike", 47); table.Rows.Add("Joe", 61); this.dataGridView1.DataSource = table; } private void button2_Click(object sender, EventArgs e) { table.Columns.Add("Height", typeof(int)); foreach (DataRow row in table.Rows) { row["Height"] = 100; } } private void button3_Click(object sender, EventArgs e) { GridViewer g = new GridViewer { DataSource = table }; g.ShowDialog(); } public partial class GridViewer : Form //just has a DataGridView on it { public GridViewer() { InitializeComponent(); } public object DataSource { get { return this.dataGridView1.DataSource; } set { this.dataGridView1.DataSource = value; } } } </code></pre> |
35,584,973 | 0 | <p>The drawing setup is quite involved, but the actual calls required to draw are fairly straightforward.

It's the <code>vkCmdDraw</code> that actually issues the command to draw, once the containing <code>VkCommandBuffer</code> is executed.</p> |

9,323,308 | 0 | <p>When a assembly' s AssemblyVersion is changed, If it has strong name, the referencing assemblies need to be recompiled, otherwise the assembly does not load! If it does not have strong name, if not explicitly added to project file, it will not be copied to output directory when build so you may miss depending assemblies, especially after cleaning the output directory. </p> |

12,483,066 | 0 | <p>I've been using <code>async</code> in production for a couple of years. There are a few core "best practices" that I recommend:</p> <ol> <li><a href="http://nitoprograms.blogspot.com/2012/07/dont-block-on-async-code.html" rel="nofollow">Don't block on <code>async</code> code</a>. Use <code>async</code> "all the way down". (Corollary: prefer <code>async Task</code> to <code>async void</code> unless you <em>have</em> to use <code>async void</code>).</li> <li>Use <code>ConfigureAwait(false)</code> wherever possible in your "library" methods.</li> </ol> <p>You've already figured out the "<code>async</code> all the way down" part, and you're at the point that <code>ConfigureAwait(false)</code> becomes useful.</p> <p>Say you have an <code>async</code> method <code>A</code> that calls another <code>async</code> method <code>B</code>. <code>A</code> updates the UI with the results of <code>B</code>, but <code>B</code> doesn't depend on the UI. So we have:</p> <pre><code>async Task A() { var result = await B(); myUIElement.Text = result; } async Task<string> B() { var rawString = await SomeOtherStuff(); var result = DoProcessingOnRawString(rawString); return result; } </code></pre> <p>In this example, I would call <code>B</code> a "library" method since it doesn't really need to run in the UI context. Right now, <code>B</code> <em>does</em> run in the UI thread, so <code>DoProcessingOnRawString</code> is causing responsiveness issues.</p> <p>So, add a <code>ConfigureAwait(false)</code> to every <code>await</code> in <code>B</code>:</p> <pre><code>async Task<string> B() { var rawString = await SomeOtherStuff().ConfigureAwait(false); var result = DoProcessingOnRawString(rawString); return result; } </code></pre> <p>Now, when <code>B</code> resumes after <code>await</code>ing <code>SomeOtherStuff</code> (assuming it did actually have to <code>await</code>), it will resume on a thread pool thread instead of the UI context. When <code>B</code> completes, even though it's running on the thread pool, <code>A</code> will resume on the UI context.</p> <p>You can't add <code>ConfigureAwait(false)</code> to <code>A</code> because <code>A</code> depends on the UI context.</p> <p>You also have the option of explicitly queueing tasks to the thread pool (<code>await Task.Run(..)</code>), and you <em>should</em> do this if you have particular CPU-intensive functionality. But if your performance is suffering from "thousands of paper cuts", you can use <code>ConfigureAwait(false)</code> to offload a lot of the <code>async</code> "housekeeping" onto the thread pool.</p> <p>You may find my <a href="http://nitoprograms.blogspot.com/2012/02/async-and-await.html" rel="nofollow">intro post helpful</a> (it goes into more of the "why's"), and the <a href="http://blogs.msdn.com/b/pfxteam/archive/2012/04/12/10293335.aspx" rel="nofollow"><code>async</code> FAQ</a> also has lots of great references.</p> |

21,016,762 | 0 | <p>There is a workaround to this problem. Consider the following implementation:</p> <pre><code>int corePoolSize = 40; int maximumPoolSize = 40; ThreadPoolExecutor threadPoolExecutor = new ThreadPoolExecutor(corePoolSize, maximumPoolSize, 60L, TimeUnit.SECONDS, new LinkedBlockingQueue<Runnable>()); threadPoolExecutor.allowCoreThreadTimeOut(true); </code></pre> <p>By setting the <a href="http://docs.oracle.com/javase/7/docs/api/java/util/concurrent/ThreadPoolExecutor.html#allowCoreThreadTimeOut%28boolean%29" rel="nofollow">allowCoreThreadTimeOut()</a> to <code>true</code>, the threads in the pool are allowed to terminate after the specified timeout (60 seconds in this example). With this solution, it is the <code>corePoolSize</code> constructor argument that determines the maximum pool size in practice, because the thread pool will grow up to the <code>corePoolSize</code>, and then start adding jobs to the queue. It is likely that the pool may never grow bigger than that, because the pool will not spawn new threads until the queue is full (which, given that the <code>LinkedBlockingQueue</code> has an <code>Integer.MAX_VALUE</code> capacity may never happen). Consequently, there is little point in setting <code>maximumPoolSize</code> to a larger value than <code>corePoolSize</code>.</p> <p>Consideration: The thread pool have 0 idle threads after the timeout has expired, which means that there will be some latency before the threads are created (normally, you would always have <code>corePoolSize</code> threads available).</p> <p>More details can be found in the JavaDoc of <a href="http://docs.oracle.com/javase/7/docs/api/java/util/concurrent/ThreadPoolExecutor.html" rel="nofollow">ThreadPoolExecutor</a>.</p> |

32,504,135 | 0 | <p>So this is how sourcemaps work in Gulp: Each element you select via <code>gulp.src</code> gets transferred into a virtual file object, consisting of the contents in a Buffer, as well as the original file name. Those are piped through your stream, where the contents get transformed.</p> <p>If you add sourcemaps, you add one more property to those virtual file objects, namely the sourcemap. With each transformation, the sourcemap gets also transformed. So, if you initialize the sourcemaps after concat and before uglify, the sourcemaps stores the transformations from that particular step. The sourcemap "thinks" that the original files are the output from concat, and the only transformation step that took place is the uglify step. So when you open them in your browser, nothing will match.</p> <p>It's better that you place sourcemaps directly after globbing, and save them directly before saving your results. <strong>Gulp sourcemaps will interpolate between transformations, so that you keep track of every change that happened</strong>. The original source files will be the ones you selected, and the sourcemap will track back to those origins.</p> <p>This is your stream:</p> <pre><code> return gulp.src(sourceFiles) .pipe(sourcemaps.init()) .pipe(plumber()) .pipe(concat(filenameRoot + '.js')) .pipe(gulp.dest(destinationFolder)) // save .js .pipe(uglify({ preserveComments: 'license' })) .pipe(rename({ extname: '.min.js' })) .pipe(sourcemaps.write('maps')) .pipe(gulp.dest(destinationFolder)) // save .min.js </code></pre> <p><code>sourcemaps.write</code> does not actually write sourcemaps, it just tells Gulp to materialize them into a physical file when you call <code>gulp.dest</code>. </p> <p>The very same sourcemap plugin will be included in Gulp 4 natively: <a href="http://fettblog.eu/gulp-4-sourcemaps/">http://fettblog.eu/gulp-4-sourcemaps/</a> -- If you want to have more details on how sourcemaps work internally with Gulp, they are in Chapter 6 of my Gulp book: <a href="http://www.manning.com/baumgartner">http://www.manning.com/baumgartner</a></p> |

4,218,266 | 0 | <p>If the readonly and readwrite entities do not share relationships, the easiest solution is to put each group in their own configuration and then have separate stores.

12,685,784 | 0 | <p>Your analysis is definitely correct about where the click event is trying to bind.</p> <p>There are two approaches I generally take:</p> <ol> <li>Use ItemClick on the List</li> <li>Continuing using Click but do some redirection on the ViewModel side.</li> </ol> <hr> <p>So...1</p> <p>The <a href="https://github.com/slodge/MvvmCross/blob/master/Sample%20-%20Tutorial/Tutorial/Tutorial.Core/ViewModels/MainMenuViewModel.cs">Main Menu</a> in the tutorial has a ViewModel a bit like:</p> <pre><code>public class MainMenuViewModel : MvxViewModel { public List<T> Items { get; set; } public IMvxCommand ShowItemCommand { get { return new MvxRelayCommand<T>((item) => /* do action with item */ ); } } } </code></pre> <p>This is used in axml as:</p> <pre><code><Mvx.MvxBindableListView xmlns:android="http://schemas.android.com/apk/res/android" xmlns:local="http://schemas.android.com/apk/res/Tutorial.UI.Droid" android:layout_width="fill_parent" android:layout_height="fill_parent" local:MvxBind="{'ItemsSource':{'Path':'Items'},'ItemClick':{'Path':'ShowItemCommand'}}" local:MvxItemTemplate="@layout/listitem_viewmodel" /> </code></pre> <p>This approach can only be done for ItemClick on the whole list item - not on individual subviews within the list items.</p> <hr> <p>Or...2</p> <p>Since we don't have any <code>RelativeSource</code> binding instructions in mvx, this type of redirection can be done in the ViewModel/Model code.</p> <p>This can be done by presenting a behaviour-enabled wrapper of the Model object rather than the Model object itself - e.g. using a <code>List<ActiveArticle></code>:</p> <pre><code>public ActiveArticle { Article _article; ArticleViewModel _parent; public WrappedArticle(Article article, ArticleViewModel parent) { /* assignment */ } public IMvxCommand TheCommand { get { return MvxRelayCommand(() -> _parent.DoStuff(_article)); } } public Article TheArticle { get { return _article; } } } </code></pre> <p>Your axml would then have to use bindings like:</p> <pre><code> <TextView ... local:MvxBind="{'Text':{'Path':'TheArticle.Label'}}" /> </code></pre> <p>and</p> <pre><code> <ImageButton ... local:MvxBind="{'Click':{'Path':'TheCommand.MyTest'}}" /> </code></pre> <p>One example of this approach is the Conference sample which uses <a href="https://github.com/slodge/MvvmCross/blob/master/Sample%20-%20CirriousConference/Cirrious.Conference.Core/ViewModels/Helpers/WithCommand.cs">WithCommand</a></p> <p>However... please note that when using <code>WithCommand<T></code> we discovered a memory leak - basically the GarbageCollection refused to collect the embedded <code>MvxRelayCommand</code> - which is why <code>WithCommand<T></code> is <code>IDisposable</code> and why <a href="https://github.com/slodge/MvvmCross/blob/master/Sample%20-%20CirriousConference/Cirrious.Conference.Core/ViewModels/SessionLists/BaseSessionListViewModel.cs">BaseSessionListViewModel</a> clears the list and disposes the WithCommand elements when views are detached. </p> <hr> <p><strong>Update after comment:</strong></p> <p>If your data list is large - and your data is fixed (your articles are models without PropertyChanged) and you don't want to incur the overhead of creating a large <code>List<WrappedArticle></code> then one way around this might be to use a <code>WrappingList<T></code> class.</p> <p>This is very similar to the approach taken in Microsoft code - e.g. in virtualizing lists in WP7/Silverlight - <a href="http://shawnoster.com/blog/post/Improving-ListBox-Performance-in-Silverlight-for-Windows-Phone-7-Data-Virtualization.aspx">http://shawnoster.com/blog/post/Improving-ListBox-Performance-in-Silverlight-for-Windows-Phone-7-Data-Virtualization.aspx</a></p> <p>For your articles this might be:</p> <pre><code>public class ArticleViewModel: MvxViewModel { public WrappingList<Article> Articles;

36,245,819 | 0 | <p>In general it depends on the target. On small targets (i.e. microcontrollers like AVR) you don't have that complex programs running. Additionally, you need to access the hardware directly (f.e. a UART). High level languages like Java don't support accessing the hardware directly, so you usually end up with C. </p> <p>In the case of C versus Java there's a major difference:</p> <p>With C you compile the code and get a binary that runs on the target. It <em>directly</em> runs on the target.</p> <p>Java instead creates Java Bytecode. The target CPU cannot process that. Instead it requires running another program: the Java runtime environment. That translates the Java Bytecode to actual machine code. Obviously this is more work and thus requires more processing power. While this isn't much of a concern for standard PCs it is for small embedded devices. (Note: some CPUs do actually have support for running Java bytecode directly. Those are exceptions though.)</p> <p>Generally speaking, the compile step isn't the issue -- the limited resources and special requirements of the target device are.</p> |

The search pattern looks for lines that match (very exactly) <code>IA/</code> followed by N or M and one or more digits, a space, and a digit 0 or 1 and end of line. The letter and digit string is captured with <code>\(...\)</code>, as is the final digit; the replacement follows the example separating the fields with a semicolon rather than a comma as stated in the question; clearly, to output a comma as stated but not shown is trivial. The line is printed (the trailing <code>p</code>) only when it matches.</p> <p>As well as the comma versus semicolon issue, this answer assumes that the required output is accurate and the NTST line should not appear. However, the wording in the question implies that maybe the NTST line should appear as well. If so, you can simplify the regex by allowing any number of non-blank characters after the N or M:</p> <pre><code>sed -n '/^IA\/\([NM][^]*\) \([01]\)$/ s//\1;\2/p' test.txt </code></pre> <p>It is not clear from that question what should happen to lines such as:</p> <pre><code>IA/N 0 IA/N Z 0 </code></pre> |

35,274,038 | 0 | <p>A few important differences:</p> <ul> <li>partially <strong>reversible</strong> (<code>CountVectorizer</code>) <strong>vs irreversible</strong> (<code>HashingTF</code>) - since hashing is not reversible you cannot restore original input from a hash vector. From the other hand count vector with model (index) can be used to restore unordered input. As a consequence models created using hashed input can be much harder to interpret and monitor.</li> <li><strong>memory and computational overhead</strong> - <code>HashingTF</code> requires only a single data scan and no additional memory beyond original input and vector. <code>CountVectorizer</code> requires additional scan over the data to build a model and additional memory to store vocabulary (index). In case of unigram language model it is usually not a problem but in case of higher n-grams it can be prohibitively expensive or not feasible.</li> <li>hashing <strong>depends on</strong> a size of the vector , hashing function and a document. Counting depends on a size of the vector, training corpus and a document. </li> <li><strong>a source of the information loss</strong> - in case of <code>HashingTF</code> it is dimensionality reduction with possible collisions. <code>CountVectorizer</code> discards infrequent tokens. How it affects downstream models depends on a particular use case and data.</li> </ul> |
