  • How to deal with overly aggressive "Link Take Down Demands"?

    - by Eoin
    I've been receiving a large number of emails recently requesting I clean from link spam from my forum. Initially the emails were very polite and professional, and I was happy to remove the links. Recently the email have gotten very abrasive, here is a particularly rude example: From: [email protected] To: [email protected] Hi, This is the second time we are reaching out to you regarding your link to our site hxxp://www.company-two.com from hxxp://www.my-forum.com/some-topic-id. We really do need to remove this link. We have to report to Google any link we were unable to remove, and I wouldn't want to have to include your site in the list. Could you please remove our link from this page and any other page on your site? Thank You, Name Changed Behind the superficial pleasantries I feel there is some very real maliciousness. Note the email address, DMCA Violations, I don't see how the DMCA is involved here, except as a word which tends to strike fear in many people. Also relating to the email address, it doesn't match the company being linked to at all. How am I to trust they are truely operating on behalf of company-two when they don't even use one of it's email addresses. My email is hidden by privacypost. While a service with legitimate uses, I feel it's highly unprofessional for communications between to companies. The claim "This is the second time..." Every email I've received has started like this, but a check of my spam filters has never revealed a 1st mail. Initially I gave them the benefit of the doubt, by now though it's clear this is a cheap ploy to start me off on the defensive. And finally worst of all- the threats of reporting me to Google if I don't do everything they ask. I sent a polite reply asking for more information. I have no idea if the email address was even valid but I never received any response. Much later I got this followup mail From: [email protected] To: [email protected] Hi, This is the final time we are reaching out to you regarding your link to our site hxxp://www.company-two.com from hxxp://www.my-forum.com/some-topic-id. We will soon be reporting to Google any link we were unable to remove, and currently your site will have to be on the list. Could you please remove our link from this page and any other page on your site? I appreciate your urgent attention to this matter. Thank You, Name Changed This time the from address was more personal, though still not obviously connected to the spammed company. Lets be honest, I don't for one second believe that the companies were the victim of a 3rd party spammer as they claim. The links in questions were generated well over a year ago, and I firmly believe the companies were directly responsible for the spam links in question, a type of spam that has plagued my forum. Now they have the audacity to demand I spend my time cleaning up their mess, using threats to ensure they get their way. Have recent changes in Googles algorithms meant all the cash they spent spamming the web has now turned into a liability? If so I can see why these companies are all of a sudden running scared. Frankly, cleaning up my forum is a good things, but the threats they are using sickens me. So my question here is specifically about the threats: Are they vaild, and would such reports to Google destroy my page rankings? Is there a way I can report this abusive behaviour to Google?

  • JavaNullPointerException/Layout Error when working with lists and ListView on Android

    - by psyhclo
    Hey, I'm trying to implement a ListView on Android, which will print the data retrieved from the SQLite Database. So I want to retrieve a lot of columns from the table and add this to a list, so I will print this list as a ListView. For this I created a method that will select all the columns from the table in a separate class, and I will print the ListView in a ListActivity. I want to retrieve 6 columns of the table, which is represented by the ids 2, 4, 5, 6, 7, 9. But it shows a lot of errors: 12-24 19:19:04.066: ERROR/AndroidRuntime(22630): FATAL EXCEPTION: main 12-24 19:19:04.066: ERROR/AndroidRuntime(22630): java.lang.NullPointerException 12-24 19:19:04.066: ERROR/AndroidRuntime(22630): at android.widget.ArrayAdapter.createViewFromResource(ArrayAdapter.java:355) 12-24 19:19:04.066: ERROR/AndroidRuntime(22630): at android.widget.ArrayAdapter.getView(ArrayAdapter.java:323) 12-24 19:19:04.066: ERROR/AndroidRuntime(22630): at android.widget.AbsListView.obtainView(AbsListView.java:1418) 12-24 19:19:04.066: ERROR/AndroidRuntime(22630): at android.widget.ListView.makeAndAddView(ListView.java:1745) 12-24 19:19:04.066: ERROR/AndroidRuntime(22630): at android.widget.ListView.fillDown(ListView.java:670) 12-24 19:19:04.066: ERROR/AndroidRuntime(22630): at android.widget.ListView.fillFromTop(ListView.java:727) 12-24 19:19:04.066: ERROR/AndroidRuntime(22630): at android.widget.ListView.layoutChildren(ListView.java:1598) 12-24 19:19:04.066: ERROR/AndroidRuntime(22630): at android.widget.AbsListView.onLayout(AbsListView.java:1248) 12-24 19:19:04.066: ERROR/AndroidRuntime(22630): at android.view.View.layout(View.java:7175) 12-24 19:19:04.066: ERROR/AndroidRuntime(22630): at android.widget.FrameLayout.onLayout(FrameLayout.java:338) 12-24 19:19:04.066: ERROR/AndroidRuntime(22630): at android.view.View.layout(View.java:7175) 12-24 19:19:04.066: ERROR/AndroidRuntime(22630): at android.widget.FrameLayout.onLayout(FrameLayout.java:338) 12-24 19:19:04.066: ERROR/AndroidRuntime(22630): at android.view.View.layout(View.java:7175) 12-24 19:19:04.066: ERROR/AndroidRuntime(22630): at android.widget.FrameLayout.onLayout(FrameLayout.java:338) 12-24 19:19:04.066: ERROR/AndroidRuntime(22630): at android.view.View.layout(View.java:7175) 12-24 19:19:04.066: ERROR/AndroidRuntime(22630): at android.widget.LinearLayout.setChildFrame(LinearLayout.java:1254) 12-24 19:19:04.066: ERROR/AndroidRuntime(22630): at android.widget.LinearLayout.layoutVertical(LinearLayout.java:1130) 12-24 19:19:04.066: ERROR/AndroidRuntime(22630): at android.widget.LinearLayout.onLayout(LinearLayout.java:1047) 12-24 19:19:04.066: ERROR/AndroidRuntime(22630): at android.view.View.layout(View.java:7175) 12-24 19:19:04.066: ERROR/AndroidRuntime(22630): at android.widget.FrameLayout.onLayout(FrameLayout.java:338) 12-24 19:19:04.066: ERROR/AndroidRuntime(22630): at android.view.View.layout(View.java:7175) 12-24 19:19:04.066: ERROR/AndroidRuntime(22630): at android.widget.FrameLayout.onLayout(FrameLayout.java:338) 12-24 19:19:04.066: ERROR/AndroidRuntime(22630): at android.view.View.layout(View.java:7175) 12-24 19:19:04.066: ERROR/AndroidRuntime(22630): at android.widget.LinearLayout.setChildFrame(LinearLayout.java:1254) 12-24 19:19:04.066: ERROR/AndroidRuntime(22630): at android.widget.LinearLayout.layoutVertical(LinearLayout.java:1130) 12-24 19:19:04.066: ERROR/AndroidRuntime(22630): at android.widget.LinearLayout.onLayout(LinearLayout.java:1047) 12-24 19:19:04.066: ERROR/AndroidRuntime(22630): at android.view.View.layout(View.java:7175) 12-24 19:19:04.066: ERROR/AndroidRuntime(22630): at android.widget.FrameLayout.onLayout(FrameLayout.java:338) 12-24 19:19:04.066: ERROR/AndroidRuntime(22630): at android.view.View.layout(View.java:7175) 12-24 19:19:04.066: ERROR/AndroidRuntime(22630): at android.view.ViewRoot.performTraversals(ViewRoot.java:1140) 12-24 19:19:04.066: ERROR/AndroidRuntime(22630): at android.view.ViewRoot.handleMessage(ViewRoot.java:1859) 12-24 19:19:04.066: ERROR/AndroidRuntime(22630): at android.os.Handler.dispatchMessage(Handler.java:99) 12-24 19:19:04.066: ERROR/AndroidRuntime(22630): at android.os.Looper.loop(Looper.java:123) 12-24 19:19:04.066: ERROR/AndroidRuntime(22630): at android.app.ActivityThread.main(ActivityThread.java:3647) 12-24 19:19:04.066: ERROR/AndroidRuntime(22630): at java.lang.reflect.Method.invokeNative(Native Method) 12-24 19:19:04.066: ERROR/AndroidRuntime(22630): at java.lang.reflect.Method.invoke(Method.java:507) 12-24 19:19:04.066: ERROR/AndroidRuntime(22630): at com.android.internal.os.ZygoteInit$MethodAndArgsCaller.run(ZygoteInit.java:839) 12-24 19:19:04.066: ERROR/AndroidRuntime(22630): at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:597) 12-24 19:19:04.066: ERROR/AndroidRuntime(22630): at dalvik.system.NativeStart.main(Native Method) Here is the code of the method that select the data. public List<String> selectAll() { List<String> list1 = new ArrayList<String>();

  • Trouble with client side validation using Struts 2. Xml based validation rules not recognized.

    - by Kartik
    Hi, This is my first post to ask a question on stack overflow and my issue is that when I don't see a client side validation error message when I don't enter any values for that field even when it is configured as required. The input page is reloaded but no error message is seen. I am not sure what I am doing wrong. Any advice would be greatly appreciated. My scenario is given below: I have a simple form where I have a pull down menu called selection criterion. A value must be selected.

  • How to correctly populate records from SQLlite in ListActivity?

    - by Pavel
    Hi. Can someone please tell me how can I easily display every record from sqllite in ListActivity tab? I'm kinda confused with this. Do I have to create db from my helper class in TabActivity or ListActivity or both? My db helper class is as follow: package tabs.app; import android.content.ContentValues; import android.content.Context; import android.database.Cursor; import android.database.SQLException; import android.database.sqlite.SQLiteDatabase; import android.database.sqlite.SQLiteOpenHelper; import android.util.Log; public class DBAdapter { private static String DB_PATH = "/data/data/tabs.app/databases/"; public static final String KEY_ROWID = "_id"; public static final String KEY_LATITUDE = "latitude"; public static final String KEY_LONGITUDE = "longitude"; private static final String TAG = "DBAdapter"; private static final String DATABASE_NAME = "coords"; private static final String DATABASE_TABLE = "coordsStorages"; private static final int DATABASE_VERSION = 2; /* private static final String DATABASE_CREATE = "create table coordsStorage (_id integer primary key autoincrement, latitude integer not null, longitude integer not null)"; */ public Context context; private DatabaseHelper DBHelper; private SQLiteDatabase db; public DBAdapter(Context ctx) { this.context = ctx; DBHelper = new DatabaseHelper(context); } private static class DatabaseHelper extends SQLiteOpenHelper { DatabaseHelper(Context context) { super(context, DATABASE_NAME, null, DATABASE_VERSION); } @Override public void onCreate(SQLiteDatabase db) { db.execSQL("create table coordsStorages (_id integer primary key autoincrement, latitude integer not null, longitude integer not null)"); } @Override public void onUpgrade(SQLiteDatabase db, int oldVersion, int newVersion) { Log.w(TAG, "Upgrading database from version " + oldVersion + " to " + newVersion + ", which will destroy all old data"); db.execSQL("DROP TABLE IF EXISTS titles"); onCreate(db); } } //---opens the database--- public DBAdapter open() throws SQLException { db = DBHelper.getWritableDatabase(); return this; } //---closes the database--- public void close() { DBHelper.close(); } //---insert a title into the database--- public long insertCoords(int latitude, int longitude) { ContentValues initialValues = new ContentValues(); initialValues.put(KEY_LATITUDE, latitude); initialValues.put(KEY_LONGITUDE, longitude); return db.insert(DATABASE_TABLE, null, initialValues); } public void openDataBase() throws SQLException{ //Open the database String myPath = DB_PATH + DATABASE_NAME; db = SQLiteDatabase.openDatabase(myPath, null, SQLiteDatabase.OPEN_READONLY); } //---deletes a particular title--- public boolean deleteTitle(long rowId) { return db.delete(DATABASE_TABLE, KEY_ROWID + "=" + rowId, null) > 0; } //---retrieves all the titles--- public Cursor getAllTitles() { return db.query(DATABASE_TABLE, new String[] { KEY_ROWID, KEY_LATITUDE, KEY_LONGITUDE}, null, null, null, null, null); } //---retrieves a particular title--- public Cursor getTitle(long rowId) throws SQLException { Cursor mCursor = db.query(true, DATABASE_TABLE, new

/*public boolean updateTitle(long rowId, int latitude, int longitude) { ContentValues args = new ContentValues(); args.put(KEY_LATITUDE, latitude); args.put(KEY_LONGITUDE, longitude); return db.update(DATABASE_TABLE, args, KEY_ROWID + "=" + rowId, null) > 0; }*/ } And Im trying to retrieve the records in TabActivity like this: public class Areas extends ListActivity { DBAdapter db; SimpleCursorAdapter mAdapter; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.areas_layout); db = new DBAdapter(this); db.open(); Cursor c = db.getAllTitles(); startManagingCursor(c); String[] display = new String[] { db.KEY_LATITUDE }; int[] to = new int[] { R.id.row_latitude}; /* String[] display2 = new String[] { db.KEY_LONGITUDE }; int[] to2 = new int[] { R.id.row_longitude};*/ mAdapter = new SimpleCursorAdapter(this, R.layout.areas_layout, c, display, to); setListAdapter(mAdapter); /* mAdapter2 = new SimpleCursorAdapter(this, R.layout.areas_layout, c, display2, to2); setListAdapter(mAdapter2);*/ db.close(); } /* private void fillData() { // Get all of the rows from the database and create the item list Cursor c = db.getAllTitles(); startManagingCursor(c); }*/ } Whenever I'm trying to do that the error log outputs this: 06-07 09:51:56.529: ERROR/AndroidRuntime(2034): Uncaught handler: thread

    Hello and I'm trying to make my own game engine in Java. I have completed all the necessary ones but I can't figure it out with the TileGame class. It just can't scroll. Also there are no exceptions. Here I'm listing the code. TileGame.java @Override public void draw(Graphics2D g) { if (back!=null){ back.render(g); } if (follower!=null){ follower.render(g); follower.draw(g); } for (int i=0; i<actors.size(); i++){ Actor actor = actors.get(i); if (actor!=follower&&getVisibleRect().intersects(actor.getBounds())){ g.drawImage(actor.getAnimation().getFrameImage(), actor.x - OffSetX, actor.y - OffSetY, null); actor.draw(g); } } } /** * This method returns the visible rectangle * @return The visible rectangle */ public Rectangle getVisibleRect(){ return new Rectangle(OffSetX, OffSetY, global.WIDTH, global.HEIGHT); } @Override public void update(){ if (follower!=null){ if (scrollHorizontally){ OffSetX = global.WIDTH/2 - Math.round((float)follower.x) - tileSize; OffSetX = Math.min(OffSetX, 0); OffSetX = Math.max(OffSetX, global.WIDTH - mapWidth); } if (scrollVertically){ OffSetY = global.HEIGHT/2 - Math.round((float)follower.y) - tileSize; OffSetY = Math.min(OffSetY, 0); OffSetY = Math.max(OffSetY, global.HEIGHT - mapHeight); } } for (int i=0; i<actors.size(); i++){ Actor actor1 = actors.get(i); if (getVisibleRect().contains(actor1.x, actor1.y)){ actor1.update(); for (int j=0; j<actors.size(); j++){ Actor actor2 = actors.get(j); if (actor1.isCollidingWith(actor2)){ actor1.collision(actor2); actor2.collision(actor1); } } } } } but the problem is that all the actors are working, but it just won't scroll. Help Please.. Thanks in Advance.

  • Tween Animation Cannot Start

    - by David Dimalanta
    Do you have any reasons why my tween code didn't run or work? I already add the tween engine onto the library folder under LibGDX project folder and "Order and Export" it under Java Build Path at the Properties menu. My first two classes ran correctly and workly but my third class didn't work. Here's the sequence: First class is the first screen. Fade animation works on the company's logo. Second class is the second screen. Fade animation for the loading screen works. Third class is the third screen. After the second screen, now calls for the third screen. Animation stopped or won't run since I want the black screen to fade out at the start when the menu is here. Can you check if I did right? Look carefully by comment lines for explanation. //-----[ Animation Setup ]----- Tween.registerAccessor(Sprite.class, new Tween_Animation()); // --> Tween_Animation.java Tween_Manager = new TweenManager(); // --> I initialized it the TweenManager and seems okay. cb_start = new TweenCallback() // --> I'll use this when I choose START and the menu will fade in black. { @Override public void onEvent(int arg0, BaseTween<?> arg1) { goTo(); } }; Tween // --> This is where I focused the problem. .to(black_Sprite, Tween_Animation.ALPHA, 3f) .target(1) .ease(TweenEquations.easeInQuad) .repeatYoyo(200, 2.5f) // --> I set the repeat for 200 times when I noticed that the animation won't work! .start(Tween_Manager);

  • New Validation Attributes in ASP.NET MVC 3 Future

    - by imran_ku07
         Introduction:             Validating user inputs is an very important step in collecting information from users because it helps you to prevent errors during processing data. Incomplete or improperly formatted user inputs will create lot of problems for your application. Fortunately, ASP.NET MVC 3 makes it very easy to validate most common input validations. ASP.NET MVC 3 includes Required, StringLength, Range, RegularExpression, Compare and Remote validation attributes for common input validation scenarios. These validation attributes validates most of your user inputs but still validation for Email, File Extension, Credit Card, URL, etc are missing. Fortunately, some of these validation attributes are available in ASP.NET MVC 3 Future. In this article, I will show you how to leverage Email, Url, CreditCard and FileExtensions validation attributes(which are available in ASP.NET MVC 3 Future) in ASP.NET MVC 3 application.       Description:             First of all you need to download ASP.NET MVC 3 RTM Source Code from here. Then extract all files in a folder. Then open MvcFutures project from mvc3-rtm-sources\mvc3\src\MvcFutures folder. Build the project. In case, if you get compile time error(s) then simply remove the reference of System.Web.WebPages and System.Web.Mvc assemblies and add the reference of System.Web.WebPages and System.Web.Mvc 3 assemblies again but from the .NET tab and then build the project again, it will create a Microsoft.Web.Mvc assembly inside mvc3-rtm-sources\mvc3\src\MvcFutures\obj\Debug folder. Now we can use Microsoft.Web.Mvc assembly inside our application.             Create a new ASP.NET MVC 3 application. For demonstration purpose, I will create a dummy model UserInformation. So create a new class file UserInformation.cs inside Model folder and add the following code,   public class UserInformation { [Required] public string Name { get; set; } [Required] [EmailAddress] public string Email { get; set; } [Required] [Url] public string Website { get; set; } [Required] [CreditCard] public string CreditCard { get; set; } [Required] [FileExtensions(Extensions = "jpg,jpeg")] public string Image { get; set; } }             Inside UserInformation class, I am using Email, Url, CreditCard and FileExtensions validation attributes which are defined in Microsoft.Web.Mvc assembly. By default FileExtensionsAttribute allows png, jpg, jpeg and gif extensions. You can override this by using Extensions property of FileExtensionsAttribute class.             Then just open(or create) HomeController.cs file and add the following code,   public class HomeController : Controller { public ActionResult Index() { return View(); } [HttpPost] public ActionResult Index(UserInformation u) { return View(); } }             Next just open(or create) Index view for Home controller and add the following code,  @model NewValidationAttributesinASPNETMVC3Future.Model.UserInformation @{ ViewBag.Title = "Index"; Layout = "~/Views/Shared/_Layout.cshtml"; } <h2>Index</h2> <script src="@Url.Content("~/Scripts/jquery.validate.min.js")" type="text/javascript"></script> <script src="@Url.Content("~/Scripts/jquery.validate.unobtrusive.min.js")" type="text/javascript"></script> @using (Html.BeginForm()) { @Html.ValidationSummary(true) <fieldset> <legend>UserInformation</legend> <div class="editor-label"> @Html.LabelFor(model => model.Name) </div> <div class="editor-field"> @Html.EditorFor(model => model.Name) @Html.ValidationMessageFor(model => model.Name) </div> <div class="editor-label"> @Html.LabelFor(model => model.Email) </div> <div class="editor-field"> @Html.EditorFor(model => model.Email) @Html.ValidationMessageFor(model => model.Email) </div> <div class="editor-label"> @Html.LabelFor(model => model.Website) </div> <div class="editor-field"> @Html.EditorFor(model => model.Website) @Html.ValidationMessageFor(model => model.Website) </div> <div class="editor-label"> @Html.LabelFor(model => model.CreditCard) </div> <div class="editor-field"> @Html.EditorFor(model => model.CreditCard) @Html.ValidationMessageFor(model => model.CreditCard) </div> <div class="editor-label"> @Html.LabelFor(model => model.Image) </div> <div class="editor-field"> @Html.EditorFor(model => model.Image) @Html.ValidationMessageFor(model => model.Image) </div> <p> <input type="submit" value="Save" /> </p> </fieldset> } <div> @Html.ActionLink("Back to List", "Index") </div>             Now just run your application. You will find that both client side and server side validation for the above validation attributes works smoothly.                      Summary:             Email, URL, Credit Card and File Extension input validations are very common. In this article, I showed you how you can validate these input validations into your application. I explained this with an example. I am also attaching a sample application which also includes Microsoft.Web.Mvc.dll. So you can add a reference of Microsoft.Web.Mvc assembly directly instead of doing any manual work. Hope you will enjoy this article too.   SyntaxHighlighter.all()

  • How can I resize a set of sprite images?

    - by Tyler J Fisher
    Hey StackExchange GameDev community, I'm attempting to resize series of sprites upon instantiation of the class they're located in. I've attempted to use the following code to resize the images, however my attempts have been unsuccessful. I have been unable to write an implementation that is even compilable, so no error codes yet. wLeft.getScaledInstance(wLeft.getWidth()*2, wLeft.getHeight()*2, Image.SCALE_FAST); I've heard that Graphics2D is the best option. Any suggestions? I think I'm probably best off loading the images into a Java project, resizing the images then outputting them to a new directory so as not to have to resize each sprite upon class instantiation. What do you think? Photoshopping each individual sprite is out of the question, unless I used a macro. Code: package game; //Import import java.awt.Image; import javax.swing.ImageIcon; public class Mario extends Human { Image wLeft = new ImageIcon("sprites\\mario\\wLeft.PNG").getImage(); //Constructor public Mario(){ super("Mario", 50); wLeft = wLeft.getScaledInstance(wLeft.getWidth()*2, wLeft.getHeight()*2, Image.SCALE_FAST); }

  • Warning: E-Business Suite Issues with Sun JRE 1.6.0_18

    - by Steven Chan
    Users need a Java client to run the Forms-based content in Oracle E-Business Suite.  With Oracle JInitiator 1.3 out of Premier Support as of July 2009, Apps users must run the native Sun Java Runtime Engine (JRE) to access this content.In early 2008 we relaxed our certification and support policy for the use of the native Sun JRE clients with the E-Business Suite. The policy reflected a switch from certifying specific JRE versions for the E-Business Suite to specifying minimum versions, instead. This permits E-Business Suite users to run any JRE release above following minimum certified levels, even later ones that Oracle hasn't explicitly tested with the E-Business Suite: JRE 1.5.0_13 and higherJRE 1.6.0_03 and higherUnder our current policy, Oracle E-Business Suite end-users can upgrade their JRE clients whenever Sun releases a new JRE release on either the 1.5 or 1.6 versions. EBS users do not need to wait for Oracle to certify new JRE 1.5 or 1.6 plug-in updates with the E-Business Suite.Known E-Business Suite Issues with JRE 1.6.0_18We test every new JRE release with both E-Business Suite 11i and 12.  We have identified a number of issues with JRE 1.6.0_18.  If you haven't already upgraded your end-users to JRE 1.6.0_18, we recommend that you to keep them on a prior JRE release such as 1.6.0_17 (6u17).

  • Why does void in C mean not void?

    - by Naftuli Tzvi Kay
    In strongly-typed languages like Java and C#, void (or Void) as a return type for a method seem to mean: This method doesn't return anything. Nothing. No return. You will not receive anything from this method. What's really strange is that in C, void as a return type or even as a method parameter type means: It could really be anything. You'd have to read the source code to find out. Good luck. If it's a pointer, you should really know what you're doing. Consider the following examples in C: void describe(void *thing) { Object *obj = thing; printf("%s.\n", obj->description); } void *move(void *location, Direction direction) { void *next = NULL; // logic! return next; } Obviously, the second method returns a pointer, which by definition could be anything. Since C is older than Java and C#, why did these languages adopt void as meaning "nothing" while C used it as "nothing or anything (when a pointer)"?

  • Why use try … finally without a catch clause?

    - by Nick Rosencrantz
    The classical way to program is with try / catch but when is it appropriate to use try without catch? In Python the following appears legal and can make sense: try: #do work finally: #do something unconditional But we didn't catch anything. Similarly one could think in Java it would be try { //for example try to get a database connection } finally { //closeConnection(connection) } It looks good and suddenly I don't have to worry about exception types etc. But if this is good practice, when is it good practice? Or reasons why this is not good practice or not legal (I didn't compile the source I'm asking about and it could be a syntax error for Java but I checked that the Python surely compiles.) A related problem I've run into is that I continue writing the function / method and at the end I must return something and I'm in a place which should not be reached and it must be a return point so even if I handle the exceptions above I'm still returning null or an empty string at some point in the code which should not be reached, often the end of the method / function. I've always managed to restructure to code so that I don't have to return null since that absolutely appears to look like less than good practice.

  • What exactly is "Web API" in ASP.Net MVC4?

    - by James P. Wright
    I know what a Web API is. I've written API's in multiple languages (including in MVC3). I'm also well practiced in ASP.Net. I just discovered that MVC4 has "Web API" and without going through the video examples I can't find a good explanation of what exactly it IS. From my past experience, Microsoft technologies (especially ASP.Net) have a tendency to take a simple concept and wrap it in a bunch of useless overhead that is meant to make everything "easier". Can someone please explain to me what Web API in MVC4 is exactly? Why do I need it? Why can't I just write my own API?

  • How to check system performance?

    - by Woltan
    Hi all, I am a new Ubuntu user and really like the look and the features of the OS. However, I have a feeling that the performance could be better. With that I mean: Somehow the scrolling within firefox of sites seems laggy. I do not know how I should measure it but there is a difference. Not that it is unusable but it is aggravating. Java programs are running really slow. As a comparison (I know it is not a fair one), I tried to run a game using wine. The graphic specifications using windows were much higher (1600x1200) with a high level of detail, and in ubuntu with the lowest level of detail 1024x768 was the maximum. (My graphics card is a GeForce GTS 450 with 1gb RAM) Coming to my question: Is there a way to measure the performance of 3D acceleration, java applets, firefox scrolling etc. with a tool and compare it with lets say a windows OS or other users having almost the same hardware? Maybe it is a setup issue where some fundamental drivers are missing or something!? Any help, link, suggestion is appreciated! Cherio Woltan

  • How to develop "Client script library" for ASP.net controls and how do these work?

    - by Niranjan Kala
    I have been working on .Net platform for 2 years and right now I am working on DevExpress controls for 6 months. All these control have client-side Events which are under some ClientScript nameSpace of particular control, Which specify ClientInstanceName, methods and properties accessible at client side. For example Button1 is ClientInstanceName and Button1.Text is a property, with methods like these: Button1.SetValue(); Button1.GetValue(); In ASP.Net Controls, buttons have the ClientClick event that fires before the Server Side Click event. I have inspected and goggled to extend client side functionality in asp.net controls. For example: create a ClientInstanceName property for controls or CheckedChanged event for CheckBox / RadioButton control. I have tried using these MSDN articles: Injecting Client-Side Script from an ASP.NET Server Control Working with Client-Side Script I got much information and ideas from these articles on how to implement/extend these. All are working in the client side. protected override void AddAttributesToRender(HtmlTextWriter writer) { base.AddAttributesToRender(writer); string script = @"return confirm(""%%POPUP_MESSAGE%%"");"; script = script.Replace("%%POPUP_MESSAGE%%", this.PopupMessage.Replace("\"", "\\\"")); writer.AddAttribute(HtmlTextWriterAttribute.Onclick, script); } Here It is just setting up attribute to the button. but all client side interaction no control from server. Here is that I want to know: How can I implement such functionality to create methods, properties etc. on client side. For example I am creating a PopControl as in the above code snippet same behavior as like Ajax ModalPopupExtender That have OK Button related properties. Ajax Controls can be directed to perform work from server side code e.g. Popup1.show(); How can I do this with such client enabled controls implemented controls as windows do? I am learning creation of Ajax Controls but I do not want to use ScriptManager or depend on another control. Just some extension to standard controls. I am expecting for ideas and implementation methods for such functionality.

  • Is it wise to ask about design decisions made on a product during an interview?

    - by Desolate Planet
    I've been thinking about interview questions lately and I've been reflecting on bad interview experiences I've had in the past. One of particular note is where I had asked the interviewer why the team chose to use Spring over EJB3 in their product. The interviewer pretty much tore my face off, yelling "Because Spring is not the be all and end all of Java software development, do you want this job or not?". In response to this, I told him that this probably wasn't the job for me and I walked out the interview. He told me at the start of the interview that they had high stuff turnover, the product had gone from Modula 3 to Perl to Java then after asking him a technical question, he went in flames. It seemed obvious to me that he was toxic to the company with that kind of attitude. Question: Is it a good idea to probe on architectural choices taken in an interview? If not, why? From my own point of view, an interview is a two-way process. If the interviewers are testing me on my technical skills, I've got every right to ask them the same questions to 1) Figure out what their mindset and attitudes towards developing software solutions are and 2) To figure out if there are in line with how I would approach problems of that kind. It's very possible that the interviewer who got angry was a bad interviewer and forgot that an interview is a two-way process. If I was asked this, I would have simply said something along the lines of wanting to leverage the container more, but I certainly wouldn't have tried to put him in a state of meek capitulation. The interviewer in question was the lead developer in the team.

  • Why learning new things is not important on a job hunt? [closed]

    - by IAdapter
    I have just finished my job hunt. I think it was about 40 job interviews, I like to travel and get to know many companies. One thing I did not like is that they don't care about new technologies. I think only 2 persons asked me about new stuff in Java world. Most of them care if I know Java (certification and many years of experiance is not enough for them, they need to test me) For example in IBM they only cared what IBM products do I know. Have I ever used any custom extensions of WebSphere? I don't understand those questions. If I learn new frameworks every day then I can learn whatever technology they have very fast. So why it matters if I have ever used those "great" custom extensions of WebSphere? After those 40 interviews I have no reason to learn any new framework, because I see that they don't care. Why those "developers" don't ask questions about new technologies? are they so long at those comapnies that they don't care about new stuff?

  • Is it bad idea to use flag variable to search MAX element in array?

    - by Boris Treukhov
    Over my programming career I formed a habit to introduce a flag variable that indicates that the first comparison has occured, just like Msft does in its linq Max() extension method implementation public static int Max(this IEnumerable<int> source) { if (source == null) { throw Error.ArgumentNull("source"); } int num = 0; bool flag = false; foreach (int num2 in source) { if (flag) { if (num2 > num) { num = num2; } } else { num = num2; flag = true; } } if (!flag) { throw Error.NoElements(); } return num; } However I have met some heretics lately, who implement this by just starting with the first element and assigning it to result, and oh no - it turned out that STL and Java authors have preferred the latter method. Java: public static <T extends Object & Comparable<? super T>> T max(Collection<? extends T> coll) { Iterator<? extends T> i = coll.iterator(); T candidate = i.next(); while (i.hasNext()) { T next = i.next(); if (next.compareTo(candidate) > 0) candidate = next; } return candidate; } STL: template<class _FwdIt> inline _FwdIt _Max_element(_FwdIt _First, _FwdIt _Last) { // find largest element, using operator< _FwdIt _Found = _First; if (_First != _Last) for (; ++_First != _Last; ) if (_DEBUG_LT(*_Found, *_First)) _Found = _First; return (_Found); } Are there any preferences between one method or another? Are there any historical reasons for this? Is one method more dangerous than another?

  • Level Creating Help

    - by Brandon oubiub
    I am making a little 2d overhead RPG type game just for fun. I have almost all the basic stuff set up, but I just need a little help on level creation. I can already make a level and place each tile how I want it, but having to place each tile gets annoying after a while. I noticed that in a lot of games, even extremely simple ones, they have LOTS of levels with LOTS of tiles in each. Creating all that in this fashion would take forever. So I guess my question is, as a game developer, am I supposed to do all that, or maybe make a little level editor so I can see things as I create it? What do game developers do? I'm using Java. EDIT: Okay, say if I had an image for a map, that I made in MS paint or photoshop, and each pixel represent a tile value, could I somehow in Java detect what color an individual pixel is?
