It says: <code>You don't have permission to access the requested object. It's either read-protected or not readable by the server.</code></p> <p>This happens when I go to <code>localhost/codeigniter/application</code></p> <p>My base URL: <code>http://localhost/codeigniter/application</code>.

29,812,375 | 0 | <p>You didn't specify what version of SQL you are using so I am doing this example in SQL Server where @cost_1 is a variable. You can adapt it to the syntax for whatever SQL variant you are using. The following will give you the counts you want as a SQL result set:</p> <pre><code>SELECT start_dsgn, COUNT(CASE WHEN min_cost_1 <= @cost_1 OR min_cost_2 <= @cost_2 THEN end_dsng END) as Cnt FROM table GROUP BY start_dsgn </code></pre> <p>Once you have that, it's up to you to convert that into whatever format you want in whichever language you are using to query the database. You also didn't specify what language you are using, but it looks like you want a dictionary where start_dsgn is the key. </p> <p>Most languages would return a list or array of either lists, tuples or dictionaries depending on what you use. From there it's pretty easy to convert them into any other form, at least in Python. Strongly typed languages like C#, Java and Swift are a little trickier.</p> |

15,803,851 | 0 | <p>You've got a query.

6,356,860 | 0 | Eclipse vs. CVS: Same Modules, Multiple Branches/Tags <p>I work on two products, each residing in its own CVS module; call them B (Base) and D (Dependent). D is dependent on B; B can exist on its own. Typically I want to have them together in my IDE environment so that I can e.g. follow API calls from D to B in the editor and debugger. These products are on distinct release schedules; a given branch/tag of D is dependent on a specific branch/tag of B. At any given time, I may be working on several different B/D branch/tag combinations.</p> <p>I'm an Eclipse noob, but I believe what we are talking about here is multiple workspaces, one for each B/D combination, and each with projects for B and D. I need to be able to create these workspaces relatively quickly, without starting completely over each time, and in such a way that the environment does not vary across the workspaces, except of course for the fact that the branch/tags are different.</p> <p>So: What do I have to do in Eclipse to accomplish my goals here? Thanks in advance...</p> <p>Mark</p> |

We have plenty of bandwidth.</li> <li>I don't mind having to resolve a conflict each time I get the latest revision, it's just one click</li> <li>It's so much more convenient than having to think about good ignore files <ul> <li>Also, if I have to add an external DLL file in the bin folder now, I can't forget to put it in source control, as the bin folder is not being ignored now.</li> </ul></li> </ul> <p>The simple solution for the last bullet-point is to add the file in a libraries folder and reference it from the project.</p> <p>Please explain if and why putting generated output files under source control is wrong.</p> |

For some reason, this compiles, and I thought to myself, "this would constitute a call to nil, wouldn't it?". So, my question is, why in the heck does this 'work'?

29,676,210 | 0 | <p>As it was <a href="http://docs.oracle.com/javase/specs/jls/se8/html/jls-15.html#jls-15.27.4" rel="nofollow">already pointed out</a>, the actual behavior is not specified by the JLS, a future version is allowed to derive from the current implementation as long as the JLS remains fullfilled.</p> <p><strong>Here is what happens in a current version of HotSpot:</strong></p> <p>Any lambda expression is bound via an <em>invokedynamic</em> call site. This call site requests a bootstrap method to bind a factory for an instance that implements the functional interface of the lambda expression. As arguments, any variables that are required to execute the lambda expression are handed to the factory. The body of the lambda expression is instead copied into a method inside of the class. </p> <p>For your example, the desuggared version would look like the following code snipped with the <em>invokedynamic</em> instruction in angle brackets:</p> <pre><code>class Foo { public static Object o = new Object(); public static Callable x1() { Object x = o; return Bootstrap.<makeCallable>(x); } private static Object lambda$x1(Object x) { return x; } public static Callable x2() { return Bootstrap.<makeCallable>(); } private static void lambda$x2() { return Foo.o; } } </code></pre> <p>The boostrap method (which is actually located in <code>java.lang.invoke.LambdaMetafactory</code>) is then asked to bind the call site on its first invocation. For lambda expressions, this binding will never change, the bootstrap method is therefore only called once. In order to being able to bind a class that implements the functional interface, the bootstrap method must first create a class at runtime which look like the following for example:</p> <pre><code>class Lambda$x1 implements Callable { private static Callable make(Object x) { return new Lambda$x1(x); } private final Object x; // constructor omitted @Override public Object call() { return x; } } class Lambda$x2 implements Callable { @Override public Object call() { return Foo.o; } } </code></pre> <p>After creating these classes, the <em>invokedynamic</em> instruction is bound to invoke the factory method that is defined by the first class to the call site. For the second class, no factory is created as the class is fully stateless. Therefore, the bootstrap method creates a singleton instance of the class and binds the instance directly to the call site (using a constant <code>MethodHandle</code>).</p> <p>In order to invoke static methods from another class, an anonymous class loader is used for loading the lambda classes. If you want to know more, I recently <a href="http://mydailyjava.blogspot.no/2015/03/dismantling-invokedynamic.html" rel="nofollow">summarized my findings on lambda expressions</a>. </p> <p>But again, <strong>always code against the spec, not the implementation</strong>. This can change!</p> |

29,993,697 | 0 | Leaflet map in ionic/angular map displays grey tiles <p>I'm working on a mapping app using ionic and leaflet. Note that I am not using the leaflet angular directive, I am using straight JS for the leaflet map (I know, I know...).</p> <p>The initial state in my app loads the leaflet map just fine. If I switch to another state and back to the map everything is also fine. However, if I launch the app, switch to a different state and open a modal window in that state, then return to the original state, the map is broken and displays a number of grey tiles. The map will not update until the browser window resizes or the orientation of the mobile device is changed.</p> <p>Here's a demo on Plunker: <a href="http://plnkr.co/edit/w67K2b?p=preview" rel="nofollow">http://plnkr.co/edit/w67K2b?p=preview</a>. To reproduce:</p> <ol> <li>Click the button at the right side of the navbar which will take you to a different state.</li> <li>Click the 'Back to map' button to go back to the original state. The map looks just fine.</li> <li>Click the button in the navbar again.</li> <li>Click the 'Open modal' button and then close the modal.</li> <li>Click the 'Back to map' button and you will see that the map is now broken.</li> </ol> <p>I've seen other people report issues with grey tiles, which typically can be resolved with a call to:</p> <pre><code>map.invalidateSize() </code></pre> <p>Unfortunately this does not resolve my issue. I'm pretty much a newb, but I think the problem is that when the modal opens, the invalidateSize() method in the leaflet source code is run, since the map div is not visible, the 'size' gets set to x:0, y:0 which ends up breaking the map when I transition back to the original state.</p> <p>I'm not really sure where to go from here. Perhaps I can use JS to dynamically resize the div and trick leaflet into thinking a resize event has occurred? How would I do this? Any other thoughts?</p> <p>Thanks!</p> |

1,037,897 | 0 | <p>I think you're thinking at too low of a level. XML is not so much "binary" as it is an abstraction on top of binary. If you want to replace snippets of XML as they come across your line, you'll have to poke into the payload portion of the packets and look for patterns of XML.. a simple way is to use a regular expression after rebuilding the bytes into content temporarily.</p> <p>Once you have this search and you have matched what you want, you can replace what you want to replace and re-send.</p> <p>The hard part of this is that you will likely need to cache some input before it leaves your machine so that you are able to find the beginning and end of what it is you are searching for. What makes this difficult is that often times, you don't know what constitutes the "beginning" and the "end" of a data payload.</p> |

But having a wear module built with beta and packaged inside the app module also built with beta does not work.</p> <p>Any ideas how I can achieve that?</p> |
27,047,590 | 0 | <blockquote> <p>JUnit's assertEquals() and such - good for tests, but can't use in main code</p> </blockquote> <p>Nothing technically prevents you from using JUnit assetions (and/or Hamcrest matchers) in your main code. Just include the Junit jar in your classpath. It's usually not done but that's more of a convention than any technical limitation.</p> <p>Java 7 also introduced <code>Objects.requireNotNull(obj, message)</code> and similar methods although not as full featured as JUnit assertions. </p> <p>but I think if you want to go with a more standardized approach Guava's preconditions is probably best.</p> |

7,438,712 | 0 | <p>The idea behind this assert is to check if first row after added ones was correctly moved. If there are some rows after inserted ones, then their data are compared.

34,829,171 | 0 | How to resize canvas and its background image while somehow maintaining the co-ordinate scale? <p>I want my canvas and background image to scale to any browser size which I have learnt is possible through this.</p> <pre><code><canvas id="canvas" style="width:100%; height:100%; background-size:100% 100%; left:0px; top: 0px;"> </code></pre> <p>Setting the width and height using percentages causes whatever I draw on top to come out blurred. The reason for this I read is that it comes out blurry because the width and height of canvas set using css is different.</p> <p>It is absolutely imperative that I keep track of the co-ordinates since I have written a collision detection logic using the original size of the image.</p> <p>Is it possible to dynamically change the canvas size to fill the screen, redraw it and ensure that the collision logic works perfectly without blurry drawing on top?</p> <p>Lets take an example here. The image floor.jpg that I want as the background of the canvas is 1200X700. I want the canvas to be 100% of the page width and height. My animated player that moves on top of it requires collision detection with walls which I have coded keeping in mind the 1200x700 image. </p> <p>I have gone through the various similar question on this site, but can't seem to figure it out.</p> |
