  • How do web-developers do web-design when freelancing?

    - by Gerald Blizz
    So I got my first job recently as junior web-developer. My company creates small/medium sites for wide variety of customers: autobusiness companies, weddign agencies, some sauna websites, etcetc, hope you get my point. They don't do big serious stuff like bank systems or really big systems, it's mostly small/medium-sized websites for startups/medium sized business. My main skills are PHP/MySQL, I also know HTML and a bit of CSS/JS/AJAX. I know that good web-developer must know some backend language (like PHP/Ruby/Python) AND HTML+CSS+JS+AJAX+JQuery combo. However, I was always wondering. In my company we have web-designer. In other serious organisations I often see the same stuff: web-developers who create business-logic and web-designers, who create design. As far as I know, after designers paint design of website they give it to developers either in PSD or sliced way, and developers put it together with logic, but design is NOT created by developers. Such separation seems very good for full-time job, but I am concerned with question how do freelance web-developers do websites? Do most of them just pay freelance designers to create design for them? Or do some people do both? Reason why I ask - I plan to start some freelancing in my free time after I get good at web-development. But I don't want to create websites with great business-logic but poor design. Neither I want to let someone else create a design for me. I like web-development very much and I am doing quite good, I like design aswell, even though I am a bit lost how to study it and get better at it. But I am scared that going in both directions won't let me become expert, it seems like two totally different jobs and getting really good in both seems very hard. But I really want to do both. What should I do? Thank you!

  • tdd is about design not verification what does it concretely mean?

    - by sigo
    I've been wondering about this. What do we exactly mean by design and verification. Should I just apply tdd to make sure my code is SOLID and not check is correct external behaviour ? Should I use Bdd for the correct behaviour part ? Where I get confused also is regarding TDD code katas, to me they looked like more about verification than design... shouldn't they be called bdd katas instead of tdd katas? I reckon that for example uncle bob bowling kata leads in the end to a simple and nice internal design but I felt that most of the process was more around vérification than design. Design seemed to be a side effect of testing incrementally the external behaviour. I didnt feel so much that we were focusing most of our efforts on design but more on vérification. While normally we are told the contrary, that in TDD, verification is a side effect, design is the main purpose. So my question is what should i focus exactly on when i do tdd: SOLID, external Api usability, what else...? And how can I do that without being focused on verification ? What do you guys focus your energy on when you are practicing TDD ?

  • Xuggle codec identification fail

    - by Thiago
    Hi there, I'm trying to run the following Xuggle code: public static boolean convert(String stream) throws IOException, InterruptedException { IMediaReader reader = ToolFactory.makeReader(stream + ".flv"); IMediaWriter writer = ToolFactory.makeWriter(stream + ".mp3", reader); reader.addListener(writer); while (reader.readPacket() != null) ; return true; } Where stream is the file path. But I'm getting the following exception: java.lang.IllegalArgumentException: could not find input codec id at com.xuggle.xuggler.IContainerFormat.establishOutputCodecId(IContainerFormat.java:393) at com.xuggle.xuggler.IContainerFormat.establishOutputCodecId(IContainerFormat.java:327) at com.xuggle.xuggler.IContainerFormat.establishOutputCodecId(IContainerFormat.java:300) at com.xuggle.mediatool.MediaWriter.addStreamFromContainer(MediaWriter.java:1141) at com.xuggle.mediatool.MediaWriter.getStream(MediaWriter.java:1046) at com.xuggle.mediatool.MediaWriter.encodeAudio(MediaWriter.java:837) at com.xuggle.mediatool.MediaWriter.onAudioSamples(MediaWriter.java:1448) at com.xuggle.mediatool.AMediaToolMixin.onAudioSamples(AMediaToolMixin.java:89) at com.xuggle.mediatool.MediaReader.dispatchAudioSamples(MediaReader.java:628) at com.xuggle.mediatool.MediaReader.decodeAudio(MediaReader.java:555) at com.xuggle.mediatool.MediaReader.readPacket(MediaReader.java:469) at <package_name>MediaFile.convert(MediaFile.java:66) at <package_name>.MediaFileTest.shouldConvertExistingFLV(MediaFileTest.java:32) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(Unknown Source) at sun.reflect.DelegatingMethodAccessorImpl.invoke(Unknown Source) at java.lang.reflect.Method.invoke(Unknown Source) at org.junit.runners.model.FrameworkMethod$1.runReflectiveCall(FrameworkMethod.java:44) at org.junit.internal.runners.model.ReflectiveCallable.run(ReflectiveCallable.java:15) at org.junit.runners.model.FrameworkMethod.invokeExplosively(FrameworkMethod.java:41) at org.junit.internal.runners.statements.InvokeMethod.evaluate(InvokeMethod.java:20) at org.junit.internal.runners.statements.RunBefores.evaluate(RunBefores.java:28) at org.junit.internal.runners.statements.RunAfters.evaluate(RunAfters.java:31) at org.junit.runners.BlockJUnit4ClassRunner.runChild(BlockJUnit4ClassRunner.java:73) at org.junit.runners.BlockJUnit4ClassRunner.runChild(BlockJUnit4ClassRunner.java:46) at org.junit.runners.ParentRunner.runChildren(ParentRunner.java:180) at org.junit.runners.ParentRunner.access$000(ParentRunner.java:41) at org.junit.runners.ParentRunner$1.evaluate(ParentRunner.java:173) at org.junit.internal.runners.statements.RunBefores.evaluate(RunBefores.java:28) at org.junit.internal.runners.statements.RunAfters.evaluate(RunAfters.java:31) at org.junit.runners.ParentRunner.run(ParentRunner.java:220) at org.eclipse.jdt.internal.junit4.runner.JUnit4TestReference.run(JUnit4TestReference.java:46) at org.eclipse.jdt.internal.junit.runner.TestExecution.run(TestExecution.java:38) at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.runTests(RemoteTestRunner.java:467) at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.runTests(RemoteTestRunner.java:683) at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.run(RemoteTestRunner.java:390) at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.main(RemoteTestRunner.java:197) The unit test is the following: @Test public void shouldConvertExistingFLV() throws IOException, InterruptedException { String str = "C:\Program Files\Wowza Media Systems\Wowza Media Server 2\content\Extremists"; //"c:/temp/corneta.flv" boolean result = MediaFile.convert(str); assertTrue(result); } So, why can't he find the codec, since I'm testing for a simple flv to mp3 conversion?

  • AlerDialog is not created - java.lang.IllegalArgumentException: Activity#onCreateDialog did not crea

    Hi, I want to create a normal AlertDialog. I used the example provided by the android dev docs. I just changed the DIALOG_PAUSED_ID to DIALOG_DELETEDB. If I execute my code and press the button which in return should create the dialog, I get the following error log: 04-29 01:01:20.973: WARN/dalvikvm(1168): threadid=3: thread exiting with uncaught exception (group=0x4001b188) 04-29 01:01:20.973: ERROR/AndroidRuntime(1168): Uncaught handler: thread main exiting due to uncaught exception 04-29 01:01:20.993: ERROR/AndroidRuntime(1168): java.lang.IllegalArgumentException: Activity#onCreateDialog did not create a dialog for id 4 04-29 01:01:20.993: ERROR/AndroidRuntime(1168): at android.app.Activity.createDialog(Activity.java:871) 04-29 01:01:20.993: ERROR/AndroidRuntime(1168): at android.app.Activity.showDialog(Activity.java:2483) 04-29 01:01:20.993: ERROR/AndroidRuntime(1168): at mjb.project.AVV.Favs.onMenuItemSelected(Favs.java:111) 04-29 01:01:20.993: ERROR/AndroidRuntime(1168): at com.android.internal.policy.impl.PhoneWindow.onMenuItemSelected(PhoneWindow.java:730) 04-29 01:01:20.993: ERROR/AndroidRuntime(1168): at com.android.internal.view.menu.MenuItemImpl.invoke(MenuItemImpl.java:139) 04-29 01:01:20.993: ERROR/AndroidRuntime(1168): at com.android.internal.view.menu.MenuBuilder.performItemAction(MenuBuilder.java:855) 04-29 01:01:20.993: ERROR/AndroidRuntime(1168): at com.android.internal.view.menu.IconMenuView.invokeItem(IconMenuView.java:525) 04-29 01:01:20.993: ERROR/AndroidRuntime(1168): at com.android.internal.view.menu.IconMenuItemView.performClick(IconMenuItemView.java:122) 04-29 01:01:20.993: ERROR/AndroidRuntime(1168): at android.view.View.onTouchEvent(View.java:4179) 04-29 01:01:20.993: ERROR/AndroidRuntime(1168): at android.widget.TextView.onTouchEvent(TextView.java:6540) 04-29 01:01:20.993: ERROR/AndroidRuntime(1168): at android.view.View.dispatchTouchEvent(View.java:3709) 04-29 01:01:20.993: ERROR/AndroidRuntime(1168): at android.view.ViewGroup.dispatchTouchEvent(ViewGroup.java:884) 04-29 01:01:20.993: ERROR/AndroidRuntime(1168): at android.view.ViewGroup.dispatchTouchEvent(ViewGroup.java:884) 04-29 01:01:20.993: ERROR/AndroidRuntime(1168): at com.android.internal.policy.impl.PhoneWindow$DecorView.dispatchTouchEvent(PhoneWindow.java:1643) 04-29 01:01:20.993: ERROR/AndroidRuntime(1168): at android.view.ViewRoot.handleMessage(ViewRoot.java:1691) 04-29 01:01:20.993: ERROR/AndroidRuntime(1168): at android.os.Handler.dispatchMessage(Handler.java:99) 04-29 01:01:20.993: ERROR/AndroidRuntime(1168): at android.os.Looper.loop(Looper.java:123) 04-29 01:01:20.993: ERROR/AndroidRuntime(1168): at android.app.ActivityThread.main(ActivityThread.java:4363) 04-29 01:01:20.993: ERROR/AndroidRuntime(1168): at java.lang.reflect.Method.invokeNative(Native Method) 04-29 01:01:20.993: ERROR/AndroidRuntime(1168): at java.lang.reflect.Method.invoke(Method.java:521) 04-29 01:01:20.993: ERROR/AndroidRuntime(1168): at com.android.internal.os.ZygoteInit$MethodAndArgsCaller.run(ZygoteInit.java:860) 04-29 01:01:20.993: ERROR/AndroidRuntime(1168): at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:618) 04-29 01:01:20.993: ERROR/AndroidRuntime(1168): at dalvik.system.NativeStart.main(Native Method) so here are the "relevant" code parts: define the ID: private static final int DELETE_DB_ID = 3; private Dialog dialog; static final int DIALOG_DELETEDB = 4; onCreateDialog(...): protected Dialog onCreateDialog(int id) { switch(id) { case DIALOG_DELETEDB: // do the work to define the pause Dialog AlertDialog.Builder builder = new AlertDialog.Builder(this); builder.setMessage("Are you sure you want to exit?") .setCancelable(false) .setPositiveButton("Yes", new DialogInterface.OnClickListener() { public void onClick(DialogInterface dialog, int id) { Favs.this.finish(); } }) .setNegativeButton("No", new DialogInterface.OnClickListener() { public void onClick(DialogInterface dialog, int id) { dialog.cancel(); } }); AlertDialog alert = builder.create(); alert.show(); break; default: dialog = null; } return dialog; } Here I try to "create" the dialog: @Override public boolean onMenuItemSelected(int featureId, MenuItem item) { switch(item.getItemId()) { case ADD_ID: createNote(); return true; case DELETE_DB_ID: showDialog(DIALOG_DELETEDB); return true; } return super.onMenuItemSelected(featureId, item); } As I already said, I just copied the code and changed the name.

  • 401 error when consuming a Web service with HTTP Basic authentication using CXF

    - by seanhodges
    I'm trying to consume a remote Web service that uses HTTP basic authentication, using Apache CXF, within a JUnit test. The error I am getting is: javax.xml.ws.WebServiceException: Failed to access the WSDL at: http://localhost:8080/services/MyService?wsdl.

I did have a read of this article and its follow-up, but so far I've had trouble determining how to go about adding the interceptor code without the use of Spring (this is for a JUnit test). How might I go about authenticating against this Web service?

  • Dataflow Programming - Patterns and Frameworks

    - by Styrac
    I just came across the proposed Boost::Dataflow library. It seems like an interesting approach and I was wondering if there are other such alternative frameworks for C++, and if there are any related design patterns. I have not ruled out Boost::Dataflow, I am just looking into any available alternatives so I can understand the domain and my options better (or roll my own if necessary).

  • What are the most common SQL anti-patterns?

    - by le dorfier
    All of us who work with relational databases have learned (or are learning) that SQL is different. Eliciting the desired results, and doing so efficiently, involves a tedious process partly characterized by learning unfamiliar paradigms, and finding out that some of our most familiar programming patterns don't work here. What are the most common antipatterns you've seen (or your self committed), whether generic or product-specific, whether in SQL statements directly, or in the ways applications build and apply them?

  • UI Code Level Patterns?

    - by DTS
    Is there a book or some other online resource that covers common code-level UI patterns (not widgets/components per se) and idioms. I'm looking for a resource that goes into some depth on MVC, event models, delegates, etc. Something in a similar vein to the POSA series would be excellent. I'm looking for something that is as platform-agnostic as possible, but I'm not sure if that even IS possible.

  • Functional Programming Equivalent of Design Patterns Book?

    - by JasonFruit
    Is there a functional-programming equivalent to the Gang of Four Design Patterns book? That is, is there a book that explains and gives examples of how commonly-needed code structures are implemented functionally? I think seeing that would give me a better idea of how to go about using in practice the functional concepts whose theory I understand.

  • Eclipc java,writting a program [closed]

    - by ghassar
    I have an important exercise for that i found in the internet please i need help in using eclipc java thanks i have to design, implement, test and document a Java program (a set of classes) for one of the following problem specifications: Problem 1 – Jubilee Estate Agency Property Management System A local Estate Agent would like a prototype system to keep track of properties that are offered for sale. The Estate Agent sells domestic and commercial properties. You will need to define classes that represent the Estate Agency System. You should design your system and the classes that you will need before starting coding. Your system must have a graphical user interface and be designed and developed using the object-oriented principles of the MVC architecture design pattern i.e. the user interface class must be separate from the other classes. The initial basic requirements for the system are as follows: • Include a list of domestic properties for sale that include details of: address, description, selling price, and number of rooms • Include a list of commercial properties for sale that include details of: address, description, selling price, and area in square metres • Enable the properties that are for sale to be viewed on the screen • Allow the customer to select one or more properties to be placed on a ‘viewing list’ so that the properties can be visited in person • Display on the screen the viewing list that shows the details of the properties chosen • Provide a basic search facility to find properties that are for sale in a particular price band and display the results • Enable a property to be marked as sold

  • Replacing build.xml with Build.java - using Java and the Ant libraries as a build system

    - by Dean Schulze
    I've grown disillusioned with Groovy based alternatives to Ant. AntBuilder doesn't work from within Eclipse, the Groovy plugin for Eclipse is disappointing, and Gradle just isn't ready yet. The Ant documentation has a section titled "Using Ant Tasks Outside of Ant" which gives a teaser for how to use the Ant libraries from Java code. There's another example here: http://www.mail-archive.com/[email protected]/msg16310.html In theory it seems simple enough to replace build.xml with Build.java. The Ant documentation hints at some undocumented dependencies that I'll have to discover (undocumented from the point of view of using Ant from within Java). Given the level of disappointment with Ant scripting, I wonder why this hasn't been done before. Perhaps it has and isn't a good build system. Has anyone tried writing build files in Java using the Ant libraries?

  • From Java GUI to Java Web

    - by Xorty
    I've been doing quite large application recently with Java - Swing. Now I'd like to move to web. Basically - I am not Microsoft guy, Java is fine with me. I've checked some basics of Java EE framework and decided that my choice will be Spring. I already am familiar with JDBC. Learning Spring is one thing, but working just with GUIs (C++ and Java) means that I have very poor knowledge of web development. Before I start reading tutorials of Spring MVC, what should I know to develop web solutions? I am mainly interested "how to" with graphics ... start from scratch or some nice IDE RAD-like development ? I kind of like f.e. Silverlight and integrating to web or asp.net win forms - allows us 'GUI' people develop faster. So can you please give me some useful advices? Thanx

  • Why does the the Java VM not recover after "Too many open files" errors?

    - by Michael
    In certain well-understood circumstances, our application will open too many sockets (database connections) and reach the maximum open files that the OS allows. We understand this; we are fixing the issue and also bumping up the limit. What we can't explain is why parts of our application don't recover even after the number of connections abates and we're well within the limit. In this case, it's an application running under Tomcat. When this happens, we first start seeing "Too many open files" errors: SEVERE: Socket accept failed java.net.SocketException: Too many open files at java.net.PlainSocketImpl.socketAccept(Native Method) at java.net.PlainSocketImpl.accept(PlainSocketImpl.java:390) at java.net.ServerSocket.implAccept(ServerSocket.java:453) at java.net.ServerSocket.accept(ServerSocket.java:421) at org.apache.tomcat.util.net.DefaultServerSocketFactory.acceptSocket(DefaultServerSocketFactory.java:61) at org.apache.tomcat.util.net.JIoEndpoint$Acceptor.run(JIoEndpoint.java:310) at java.lang.Thread.run(Thread.java:619) Eventually, we start seeing NoClassDefFoundErrors inside an application thread that's trying to open HTTP connections: java.lang.NoClassDefFoundError: org/apache/commons/httpclient/protocol/ControllerThreadSocketFactory at org.apache.commons.httpclient.protocol.DefaultProtocolSocketFactory.createSocket(DefaultProtocolSocketFactory.java:128) at org.apache.commons.httpclient.HttpConnection.open(HttpConnection.java:707) at org.apache.commons.httpclient.MultiThreadedHttpConnectionManager$HttpConnectionAdapter.open(MultiThreadedHttpConnectionManager.java:1349) [...] Caused by: java.lang.ClassNotFoundException: org.apache.commons.httpclient.protocol.ControllerThreadSocketFactory at org.apache.catalina.loader.WebappClassLoader.loadClass(WebappClassLoader.java:1387) at org.apache.catalina.loader.WebappClassLoader.loadClass(WebappClassLoader.java:1233) at java.lang.ClassLoader.loadClassInternal(ClassLoader.java:320) ... 8 more When the errant connections go away, the server starts accepting connections again, and everything seems ok, but we're left with the latter error constantly being spewed to stderr. Although the application typically logs unloaded classes to stdout, I don't see any such logs just before, during or after the "Too many open files" errors. My initial theory was that the Hotspot JVM would unload seemingly unused classes when it encounters "Too many open files," but if so, it doesn't log the fact. I'd also expect it to recover if that were the case. Platform details: Java(TM) SE Runtime Environment (build 1.6.0_14-b08) Java HotSpot(TM) 64-Bit Server VM (build 14.0-b16, mixed mode) Apache Tomcat Version 6.0.18

    I got a thread dump of one of my processes. It has a bunch of these threads. I guess they are keeping a bunch of memory so I am getting OOM.

CustomThreadedExtractorWrapper is a wrapper class that fires a thread to do some work (ExtractionThread, which uses ZipExtractorCommonsCompress to extract zip contents from a compressed stream). If the task is taking too long, ExtractionThread.interrupt(); is called to cancel the operation. I can see in my logs that the cancellation happened 25 times. And I see 21 of these threads in my dump. My questions: What is the status of these threads? Alive and running? Blocked somehow? They did not die with .interrupt() apparently? Is there a sure way to really kill a thread? What does really mean 'locked ' in the stack trace? Line 223 in Inflater.java is: public synchronized int inflate(byte[] b, int off, int len) { ... //return is line 223 return inflateBytes(b, off, len); }
