4,956,245 | 0 | How to manage shared resources for several web apps in Maven AND Eclipse? <p><em>Note: I didn't get any response in the first version of this question, so I modified it to be more generic...</em></p> <p><strong>Context</strong></p> <p>My project is divided into several maven modules and several web-applications. Here is the structure:</p> <pre><code>my-project + pom.xml +-- commons +-- persistence +-- ... +-- web-app-1 +-- web-app-2 +-- ... </code></pre> <p>All the web applications share common resources, such as JS, CSS and images files.</p> <p>Instead of duplicating these resources in each <code>web-app-X</code>, I decided to create another project called <code>web-resources</code>, which is a WAR project. The structure is then the following one:</p> <pre><code>my-project + pom.xml +-- commons +-- persistence +-- ... +-- web-app-1 +-- web-app-2 +-- ... +-- web-resources +-- pom.xml +-- src/main/webapp +-- web.xml (which is almost empty, just need to be present for Maven) +-- web_resources +-- css +-- images +-- javascript </code></pre> <hr/> <p><strong>Maven</strong></p> <p>In Maven 2 (or Maven 3, as I just migrated my project to maven 3.0.2), this configuration is easy to manage as all <code>web-app-X</code> declare <code>web-resources</code> as a dependency:</p> <pre><code><groupId>foo.bar</groupId> <artifactId>web-app-1</artifactId> ... <dependencies> <dependency> <groupId>foo.bar</groupId> <artifactId>web-resources</artifactId> <version>${preclosing-version}</version> <type>war</type> </dependency> ... </code></pre> <p>So when I build my WAR project, it first get the <code>web-resources.war</code> (built just before), unzip it, and build <em>on top of it</em> the <code>web-app-X</code> web-application. This way, my WAR file will contains also a directory called <code>web-resources/</code> that contains the shared resources.</p> <p>This is the war overlay principle.</p> <p>So on a Maven point of view, everything is fine!</p> <hr/> <p><strong>Eclipse</strong></p> <p>Now, here comes the main problem: having a good Eclipse configuration.</p> <p><em>Question</em>: How can I use my current configuration to be managed correctly by Eclipse? In particular, when I deploy any <code>web-app-X</code> in Tomcat using Eclipse...</p> <p>Note that I want to get the more automatizable (?) configuration, and avoid any manual steps, as this configuration should be used by dozens of developers...</p> <p>For me, the best solution seems to use the <em>linked resources</em> of Eclipse. Thus, I set the following configuration in my <code>web-app-X</code> pom.xml:</p> <pre><code><build> <plugins> <plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-eclipse-plugin</artifactId> <configuration> <wtpversion>1.5</wtpversion> <linkedResources> <linkedResource> <name>web_resources</name> <type>2</type> <location>${project.basedir}\..\web-resources\src\main\webapp\web_resources</location> </linkedResource> </linkedResources> </configuration> </plugin> ... </code></pre> <p>When I run the <code>mvn eclipse:eclipse</code> configuration, it adds succesfully this information in my <code>.project</code> file:</p> <pre><code><projectDescription> ... <linkedResources> <link> <name>web_resources</name> <type>2</type> <location>C:\dev\project\web-resources\src\main\webapp\web_resources</location> </link> </linkedResources> <projectDescription> </code></pre> <p>Now, I import my project in Eclipse. Problem: in <code>Project properties > Java Build Path > Source</code>, I don't see the Link Source present. I only see my four Maven default directories (<code>src/main/java</code>, <code>src/main/resources</code>, <code>src/test/java</code> and <code>src/test/resources</code>). What is strange is that when I try to manually add the linked resources, it refuses and says that it already exists...</p> <p>So when I deploy my web application on my Tomcat in Eclipse, it does <em>not</em> deploy the web_resources directory, and thus I don't get the CSS / JS / images deployed. </p> <p>After some tests, it seems that I have to do two modifications:</p> <ol> <li>Add the line <code><classpathentry kind="src" path="web_resources" output="src/main/webapp/web_resources"/></code> in my <code>.classpath</code> file;</li> <li>Remove the <code><project>preclosing-web-resources</project></code> in the <code>.project</code> file.</li> </ol> <p>Note that using this configuration, Eclipse will copy (and keep synchronization) the content of web_resources project in my <code>web-app-X/src/main/webapp/web_resources</code>, but this is not a problem (this directory is ignored by the SCM).</p> <p>The only automated solution I found was to create a simple Maven plugin that do the two previous modification, and then run the following command (or use a .bat file):</p> <pre><code>mvn eclipse:clean eclipse:eclipse myEclipsePlugin:eclipse </code></pre> <hr/> <p><strong>Question</strong></p> <ul> <li>Is there a better way to manage such configuration?</li> </ul> <hr/> <p><em>Technical information</em></p> <p>Java 6, Maven 3.0.2, maven eclipse plugin 2.8, Eclipse 3.3.2 (but I can test with newer version of Eclipse), <strong>no</strong> m2eclipse plugin.</p> |

Unfortunately newuser probably now looks like:</p> <pre><code> $ id uid=22(newuser) gid=22(newuser) groups=22(newuser), 455(giri26) … </code></pre> <p>and since newuser might never log in to a shell nor even have a password, there is no good place to run newgrp. </p> <p>To fix it, you should make giri26 the gid of newuser by modifying <code>/etc/passwd</code></p> <pre><code>newuser:x:22:22: … </code></pre> <p>becomes:</p> <pre><code>newuser:x:22:455: … </code></pre> <p>This could have effects on newuser's other files and directories, be wary.</p> |

19,215,331 | 0 | <p>From what I can tell, your paint code should work fine</p> <p>The problem is, most likely, in the fact that the images are not loading, but since you've chosen to ignore any errors that are raised by this process, you won't have any idea why...</p> <p>So, instead of <code>// dont know</code>, use <code>e.printStackTrace()</code> when loading your images</p> <pre><code>for (int i = 0; i < 5; i++) { try { URL url = new URL(getCodeBase(), imageString[i]); images[i] = ImageIO.read(url); } catch (IOException e) { e.printStackTrace(); } } </code></pre> <p>This will at least provide you with some more clues as to the problems you are facing.</p> <p>You should also avoid using AWT (<code>Button</code>) components on Swing (<code>JAppelt</code>) containers. They tend not to play nice well together.</p> <p>Having said all that, I would encourage you not to use <code>JAppelt</code> as a learning tool. Applets come with a swag of their own issues which are difficult to diagnose at the best of times, more so when you're trying to learn Java and the Swing API. The Swing API is complex enough with adding unnecessary challenges.</p> <p>You should also avoid extending from top level containers (in this case, you have no choice), but you should also avoid painting directly to top level containers. Apart from the complexities of the paint process, they are not double buffered, which introduces flickering when the UI is updated.</p> <p>Instead, start with something like a <code>JPanel</code> and override it's <code>paintComponent</code> method. <code>JComponent</code>s are double buffered by default, so they won't flicker when they are repainted. You must also call <code>super.paintXxx</code>. As I said, the paint process is a complex process, each <code>paintXxx</code> method is a link in the chain, if you break the chain, you should be prepared for some strange and unexpected behaviour down the track.</p> <p>Once you have your component setup, you are free to choose how to deploy it, by adding it to something like a <code>JFrame</code> or <code>JApplet</code>, making your component more flexible and reusable.</p> <p>Take a look at <a href="http://docs.oracle.com/javase/tutorial/uiswing/painting/" rel="nofollow">Performing Custom Painting</a> for more details</p> <p>The next question that comes to mind is why? Why do any custom painting at all, when <code>JLabel</code>s will not only do the job, but would probably do it better.</p> <p>Take a look at <a href="http://docs.oracle.com/javase/tutorial/uiswing/" rel="nofollow">Creating an GUI with Swing</a> for more details...</p> |

19,468,225 | 0 | <p>Although technically it is possible as Aladdin has answered, I would strongly suggest you not to use PHP/Yii for this. Neither Yii nor PHP is desgined for this sort of work. Yii is really a wonderful framework but it won't really help you with GA programming. PHP is versatile and fast, great for scripting etc. But it is not designed to be used in cases of GA where you will run many generations and runtime performance is a big factor. C++ or similar performing languages you should be considering.</p> <p>You mentioned time as a constraint both run time and development time. I would advice you to use a existing python/C++ library for GA algorithims and quickly implement the same </p> <p>Python Library: <a href="http://pyevolve.sourceforge.net/" rel="nofollow">http://pyevolve.sourceforge.net/</a> Source here: <a href="https://github.com/perone/Pyevolve" rel="nofollow">https://github.com/perone/Pyevolve</a></p> <p>C++ Library: <a href="http://lancet.mit.edu/ga/" rel="nofollow">http://lancet.mit.edu/ga/</a></p> <p>If performance of the algorithm is extremely important then C++ is the obvious choice. If presentation and flexibility then use the Python one, which I prefer personally. </p> <p>However if you wish to still use Yii/PHP, i suggest you compile these programs and call them in a console application / command in Yii and just use Yii to process the parameters store and display the output. </p> |

Normally, a server VM uses the interpreter to collect profiling information about methods that is fed into the compiler. In the tiered scheme, in addition to the interpreter, the client compiler is used to generate compiled versions of methods that collect profiling information about themselves. Since the compiled code is substantially faster than the interpreter, the program executes with greater performance during the profiling phase. In many cases, a startup that is even faster than with the client VM can be achieved because the final code produced by the server compiler may be already available during the early stages of application initialization. The tiered scheme can also achieve better peak performance than a regular server VM because the faster profiling phase allows a longer period of profiling, which may yield better optimization.</p> </blockquote> |

6,658,394 | 0 | C++, Can't find loaded C# DLL while enumerating loaded modules <p>thank you for taking the time to read this.</p> <p>The situation is basically, I'm using EnumProcessModulesEx to enumerate all the modules in a loaded process. I've verified that the process I'm getting with GetCurrentProcess is correct (via the ID). I seem to be getting all the loaded modules except the one I want! It's a C# DLL that is only loaded when the C# DLL function is called. I made sure the DLL was loaded before I ran the enumerating function. Is there a reason this C# DLL won't show up?</p> <p>I also put this enumeration after I load a couple of other C# DLLs in my C++ code. It doesn't seem to be finding those either. All of these C# DLLs are dynamically loaded. I figure it shouldn't matter because a) everything is mapped into the process address space anyways, and b) I have a C++ DLL that is injected (dynamically loaded?) and I can find that just fine. My goal is to be able to hook a C# DLL function, so being able to find these C# DLLs is a must in this project. </p> <p>Thank you all again for any tips or insights! =)</p> |

14,760,056 | 0 | <p>I think you are going the wrong way. Backpropagation isn't a good choice for this type of learning (somehow incremental learning). To use backpropagation you need some data, say 1000 data where <strong>different types of similaritiy (input)</strong> and the <strong>True Similarity (output)</strong> are given. Then weights will update and update until error rate comes down. And besides you need test data set too that will make you sure the result network will do good even for similarity values it didn't see during training.</p> |

15,722,041 | 0 | <p>There is currently not a managed DLL available from Microsoft that wraps the Management API; however, there are a few other options. First, there are command line tools such as the PowerShell CmdLets and the CLI tools found at <a href="http://www.windowsazure.com/en-us/downloads/" rel="nofollow">http://www.windowsazure.com/en-us/downloads/</a>. If you only need to script these calls to delete the deployment these will work for you just fine. In my opinion I would suggest NOT looking at csmanage as that is an old sample and not maintained. The command line tools are the replacement.</p> <p>Second, you can do so using code to call the REST based management API much like Neil indicated in the first link you included in your question. The documentation for the API can be found at <a href="http://msdn.microsoft.com/en-us/library/windowsazure/ee460812.aspx" rel="nofollow">http://msdn.microsoft.com/en-us/library/windowsazure/ee460812.aspx</a>.

Just like Neil's examples you'll use calls direct to the REST API. </p> |

11,384,315 | 0 | django radio buttons in forms <p>I have a form in Django with radio buttons that have various properties for users. When an admin user (in my application...not the django admin) wants to edit properties for different users, the same form objects should appear for all users in a list. So say there is a list of possible permissions for users, I have a table with the list of users, and the user permissions options (radio buttons) should appear next to them. In the form I have a radio button choice field with all available permissions. But in the view, how do I get it to appear for each user? Also, how do I set initial data when there're are many of the same form object? Is there an example of this somewhere?

13,744,223 | 0 | <p>Option 1 using pointers is a bad idea. Use either <code>boost::scoped_ptr</code> or, if you can, <a href="http://herbsutter.com/elements-of-modern-c-style/" rel="nofollow"><code>std::unique_ptr</code></a>.</p> <p>Option 2, as you implement it, should not be used. See <a href="http://www.gotw.ca/gotw/028.htm" rel="nofollow">GotW #28: The Fast Pimpl Idiom</a>. In C++11 however, this can be done correctly using <code>std::aligned_storage<></code>. I once wrote a <code>pimpl_ptr<T, Size, Align=default></code> that does the casting, copying, destructor call for you and checks that you have chosen the right <code>Size</code>.</p> <p>In general, use pimpl unless you have profiled and shown that this is the bottleneck.</p> <p>But as always, don't reinvent the wheel.

31,479,681 | 0 | <ol> <li><p>The variables <code>jpg_data</code> and <code>png_data</code> are lists containing captured URLs. Your loops iterate over each URL, placing the URL string in the variable <code>image</code>. Then, in both loops, you write the URL string to the file, not the actual image. It actually looks like the commented out <code>urllib</code> lines would do the trick, instead of what you're currently doing now.</p></li> <li><p>The <code>.write()</code> function expects you to give it an object that matches the mode of the file. When you call <code>open(..., 'wb')</code>, you're saying to open the file in <code>write</code> and <code>binary</code> mode, which means that you need to give it <code>bytes</code> instead of <code>str</code>.</p></li> </ol> <p>Bytes are the fundamental way everything is stored in a computer. Everything is a series of bytes -- the data on your hard drive, and the data you send and receive on the Internet. Bytes don't really have meaning on their own -- each one is just 8 bits strung together. The meaning depends on how you <em>interpret</em> the bytes. For instance, you could interpret a single byte as representing a number from 0 to 255. Or, you could interpret it as a number from -128 to 127 (both of these are common). You could also assign these "numbers" to characters, and interpret a sequence of bytes as text. However, this only allows you to represent 256 characters, and there are many more than that in the world's various languages. So, there are multiple ways of representing text as sequences of bytes. These are called "character encodings". The most popular modern one is "UTF-8".</p> <p>In Python, a <code>bytes</code> object is just a series of bytes. It has no special meaning -- nobody has said what it represents yet. If you want to use that as text, you need to decode it, using one of the character encodings. Once you do that (<code>.decode('UTF-8')</code>), you have a <code>str</code> object. In order to write it to disk (or the network), your <code>str</code> will have to eventually be <em>encoded</em> back into bytes. When you open a file in text mode, Python chooses your computer's default encoding, and it will decode everything you read using that, and encode everything you write with it. However, when you open a file in <code>b</code> mode, Python expects that you will give it <code>bytes</code>, and so it throws an error when you give it a <code>str</code> instead. Since you know the HTML file you downloaded and put in <code>data</code> is text, it would have been best for you to save it to a file in text mode. However, encoding it as <code>UTF-8</code> and writing it to a binary file works too, as long as your system's default encoding is <code>UTF-8</code>. In general, when you have a <code>str</code> and you want to write it to a file, open the file in text mode (just don't pass <code>b</code> in the mode parameter) and let Python pick the encoding, since it knows better than you do!</p> <p>For more info on the character sets and encoding stuff (which I only glossed over), you really should read <a href="http://www.joelonsoftware.com/articles/Unicode.html" rel="nofollow">this</a> article.</p> |
