5,922,758 | 0 | Mimicking Google Account on the server-side <p>I recently bought an Android device. Now I'm wondering if can I mimic protocols it uses to communicate with Google servers? I basically want to setup some kind of "Google account", which wouldn't be served by Google, but would be fully compatible with Android devices. So, does Android use some kind of WebDAV protocol for accessing things like calendar, contacts? What kind of protocol does it use for mail (is it IMAP, as I would configure my account on a PC or some other Google-only-knows-what-is-it protocol?) Or do I just have to mimic GData protocols? Is there even a way to change host which Android talks to?</p> <p>I know that there are things like Google Apps. They allow you to setup your own, very little part of Google, which AFAIK can be connected to Android device (you just have to create an Google account with your domain after username, I suppose), but everything's still hosted on Google servers and Android still talks to Google host.</p> <p>If nothing works out, I could probably create some kind of service provider, which would act like those for Facebook, Twitter and Google, but for now I want to explore possibility of doing it on the server-side.</p> <p>Not that I don't trust Google. I just don't really like someone handling valuable part of my life in files I don't own. Assume this question void if someone found a way of <code>chown</code>ing files on Google servers ;). </p> |

24,499,272 | 0 | Exported jar finds some files (not all) even though the paths are the same <p>When I run my program from eclipse, it shows up fine, the images from Resources\ show up, as do the sounds from the same place, and the text files are found properly. However, when I export my jar, and copy the resources into it with 7Zip, the images will work, but the sounds and the text files can't be found, even though they're in the same folder, with the same path used to find them in my code. I can fix this by putting a folder next to the jar file named Resources, and put everything in there, but I'd like to know why just putting it in the jar file only worked for the images, and how I can get it to work with the text and audio files as well. An example to show you what I mean:</p> <pre><code>File inventory = new File("Resources/inv.txt"); threadpath = "Resources/threads.wav"; enemy1 = new Sprite(new Texture("Resources/miniForestGolem.png")); </code></pre> <p>When I run it in eclipse, all three work fine, but when I export it, and put the resources folder in the jar file, only the image works.</p> <p><strong>Edit:</strong></p> <p>I know how to include my resources, and have done so, I'm asking about <em>how/why some of the resources aren't able to be accessed</em>, even after adding them in.</p> |

14,057,484 | 0 | <p>You can use 2 comprehensions to naturally loop over the data structures.</p> <pre><code>dict((drug, [file for file in file_list if drug in file]) for drug in drug_list) </code></pre> <p>Let's break this down. We'll need to create a dictionary, so let's use a list comprehension for that.</p> <pre><code>dict((a, str(a + " is the value")) for a in [1, 2, 3]) </code></pre> <p>The outermost part is a list comprehension that creates a dict. By creating 2-tuples of the form (key, value) we can then simply call dict() on it to get a dictionary. In our answer, we set the drug as the key and we set the value to a list that is built from another list comprehension. So far we have:</p> <pre><code>{'17A': [SOMETHING], '56B': [SOMETHING], '96A': [SOMETHING]} </code></pre> <p>Now we need to fill in the SOMETHINGs and this is what the inner comprehension does. It looks like your logic is to check if the drug text appears in the file. We already have the drug, so we can just say:</p> <pre><code>[file for file in file_list if drug in file] </code></pre> <p>This runs through the file list and adds it if the drug appears therein.</p> <p>In Python 2.7 and above, you can use a dictionary comprehension instead of using dict(). In that case it would look like:</p> <pre><code>{drug: [file for file in file_list if drug in file] for drug in drug_list} </code></pre> <p>This is much clearer since all the boiler plate of making 2-tuples and converting can be done away with.</p> <p>Comprehensions are an excellent way of writing code because the tend to be very clear descriptions of what you mean to do. It's worth noting that this is not the most efficient way of building the dictionary though, since it runs through every file for every drug. If the list of files is very long this could be very slow.</p> <p><em>Edit: My first answer was nonsense. As penance, I have made this detailed one.</em></p> |

16,309,863 | 0 | Binding to interface typed properties <p>I just got bit by yet another binding oddity in WPF. Consider the following class and its <code>IStupid</code> typed property called <code>MyStupid</code>:</p> <pre><code>public struct DumbClass { public IStupid MyStupid { get { return new IsStupid(); } } } public interface IStupid{} public class IsStupid : IStupid{} </code></pre> <p>Now consider the following binding to a <code>ListBox</code>:</p> <pre><code>var items = new List<DumbClass>(new []{new DumbClass(), new DumbClass(), new DumbClass()}); OptListBox.ItemsSource = items; </code></pre> <p>There is nothing special about the xaml:</p> <pre><code><ListBox Name="OptOccurances" Height="238" HorizontalAlignment="Left" Margin="130,34,0,0" VerticalAlignment="Top" Width="229" > </ListBox> </code></pre> <p>As expected, the output of the listbox is 3 rows of "MyProject.DumbClass".</p> <p>However if I set <code>DisplayMemberPath="MyStupid"</code> (or create an ItemTemplate, binding 'MyStupid' directly to a TextBlock in the template), I get 3 empty rows instead, when I expected it to say <code>MyProject.IsStupid</code>.

15,905,789 | 0 | <p>First, a general note, as stated by the <a href="http://developer.android.com/reference/android/os/AsyncTask.html" rel="nofollow">Android Docs</a>:</p> <p><code>AsyncTasks should ideally be used for short operations (a few seconds at the most). If you need to keep threads running for long periods of time, it is highly recommended you use the various APIs provided by the java.util.concurrent pacakge such as Executor, ThreadPoolExecutor and FutureTask.</code></p> <p>To answer your questions:</p> <ol> <li>Yes - you can use Async task as if it were just a background thread - an Async task is merely a wrapper of <code>Thread</code> and <code>Handler</code> that allows the thread to seamlessly communicate with the UI thread. <strong>Warning!</strong> If you plan to update the UI thread, or otherwise reference an activity or fragment in the callbacks that reference the UI thread (i.e. onProgressUpdated and/or onPostExecute) you should explicitly check that the activity or fragment is still in a state from which it can be referenced and used. For example - here's the right and wrong way to do it when launching an AsyncTask from a fragment:</li> </ol> <p>Create your task with a ref to the activity so you can do something when it's done:</p> <pre><code>private class DownloadFilesTask extends AsyncTask<URL, Integer, Long> { Fragment mFragment; public DownloadFilesTask(Fragment fragment){ mFragment = fragment; } </code></pre> <p>WRONG: </p> <pre><code> protected void onPostExecute(Long result) { // if the fragment has been detached, this will crash mFragment.getView().findView... } </code></pre> <p>RIGHT:</p> <pre><code> protected void onPostExecute(Long result) { if (mFragment !=null && mFragment.isResumed()) ... do something on the UI thread ... } } </code></pre> <ol> <li><p>If the Activity dies while an AsyncTask is executed, it will continue to run. Using the techniques listed above, you can avoid crashes by checking the lifecycle of the context that started the task. </p></li> <li><p>Finally, if you have a very long-running operation that does not require the UI thread at all, you should look into using a <a href="http://developer.android.com/reference/android/app/Service.html" rel="nofollow">Service</a>. Here's a blurb:</p></li> </ol> <p><code>A Service is an application component representing either an application's desire to perform a longer-running operation while not interacting with the user or to supply functionality for other applications to use</code> </p> |

7,362,028 | 0 | <p>Here's a solution that works like the Evernote login screen:</p> <p>First, define a class that will be your special LinearLayout like this:</p> <pre><code>public class MyLayout extends LinearLayout { public MyLayout(Context context, AttributeSet attrs) { super(context, attrs); } public MyLayout(Context context) { super(context); } private OnSoftKeyboardListener onSoftKeyboardListener; @Override protected void onMeasure(final int widthMeasureSpec, final int heightMeasureSpec) { if (onSoftKeyboardListener != null) { final int newSpec = MeasureSpec.getSize(heightMeasureSpec); final int oldSpec = getMeasuredHeight(); if (oldSpec > newSpec){ onSoftKeyboardListener.onShown(); } else { onSoftKeyboardListener.onHidden(); } } super.onMeasure(widthMeasureSpec, heightMeasureSpec); } public final void setOnSoftKeyboardListener(final OnSoftKeyboardListener listener) { this.onSoftKeyboardListener = listener; } public interface OnSoftKeyboardListener { public void onShown(); public void onHidden(); } } </code></pre> <p>This layout listens to measure changes, and if new measurements are < than the old ones, that means part of the screen is eaten by soft keyboard.</p> <p>Though, for it to work, in your manifest you need to set <code>android:windowSoftInputMode="adjustResize"</code> so the content will be resized and not just shifted.</p> <p>And the whole system works as follows: You have your layout:</p> <pre><code><MyLayout id="layout"> <SomeImage id="image"/> <SomeText> <SomeInput> </MyLayout> </code></pre> <p>It's like evernotes login screen. Then, in your activity:</p> <pre><code>((MyLayout)findViewById(R.id.layout)).setOnSoftKeyboardListener(new OnSoftKeyboardListener() { @Override public void onShown() { findViewById(R.id.image).setVisibility(View.GONE); } @Override public void onHidden() { findViewById(R.id.image).setVisibility(View.VISIBLE); } }); </code></pre> <p>Then go to manifest.xml and set </p> <pre><code>android:windowSoftInputMode="adjustResize" </code></pre> <p>What will happen, is when soft keyboard is shown, it'll hide the image and will resize the rest of content. (You can actually see how text is resized in Evernote)</p> <p>Image hide is, of course, one of the many things you can do. But you must be careful, since different layout changes will also call onMeasure.</p> <p>Of course it's a dirty variant. You need to check for orientation changes, and the right time when actually take the measurements, and maybe some more logic when comparing the new specs with the old ones. But i think this is the only way to do it.</p> |

12,761,896 | 0 | <p>A primary key in database design should be seen as a unique identifier of the info being represented. By removing an ID from a table you are essentially saying that this record shall be no more. If something was to take its place you are saying that the record was brought back to life. Now technically when you removed it in the first place you should have removed all foreign key references as well. One may be tempted at this point to say well since all traces are gone than there is no reason something shouldn't take it's place. Well, what about backups? Lets say you removed the record by accident, and it ended up replaced by something else, you would not be able to easily restore that record. This could also potentially cause problems with rollbacks. So not only is reusing ID's not necessary but fundamentally wrong in the theory of database design.</p> |

1,153,940 | 0 | <p>This is not really a programming question, but more of the management question.</p> <p>Missed deadlines are rarely developer's fault. As a developer you should try your best to do as good work as you can, but in the end everyone is capable of only so much. If developers put in honest effort and despite this the deadline was missed, it means that the deadline was unrealistic to begin with.</p> <p>Dealing with deadlines is responsibility of managers. There are different approaches but none of them include "penalizing" developers for doing their job. An important thing to understand here is the so-called project management <a href="http://en.wikipedia.org/wiki/Project_triangle" rel="nofollow noreferrer">triangle</a>. What it means is that software project can be good (i.e. meeting requirements, good quality), fast (meeting deadlines) and cheap (headcounts, tools). The trouble is that only 2 out of these 3 properties can be chosen.</p> <p>So if management want something good and fast - it is not going to be cheap.</p> <p>If management want something good and cheap - it won't be fast.</p> <p>And finally if management want cheap and fast - guess what, it won't be any good.</p> <p>So the correct response to missed deadline depends on the chosen scenario. Good and fast requires adding some extra help, better tools, investment in above-average developers and more. </p> <p>Good and cheap by definition assumes that deadlines are going to be missed (Blizzard, makers of World Of Warcraft are good example of this approach)</p> <p>And finally cheap and fast usually means cutting features and releasing with bugs.</p> |

12,851,914 | 0 | <p>No. Once a blob is created/uploaded you can't change the blob type. Unfortunately you would need to recreate/re-upload the blob. However I'm somewhat surprised. You mentioned that you copied the blob from one storage account to another. Copy Blob operation within Windows Azure (i.e. from one storage account to another) preserves the source blob type. It may seem a bug in CloudBerry explorer. I wrote a blog post some days ago about moving virtual machines from one subscription to another (<a href="http://gauravmantri.com/2012/07/04/how-to-move-windows-azure-virtual-machines-from-one-subscription-to-another/">http://gauravmantri.com/2012/07/04/how-to-move-windows-azure-virtual-machines-from-one-subscription-to-another/</a>) and it has some sample code and other useful information for copying blobs across storage account. You may want to take a look at that. HTH.</p> |
10,649,734 | 0 | <p>Sounds like you need some sort of a mechanism to correlate requests to the different plugins available. Ideally, there should be a different URL path per set of operations published for each plugin. </p> <p>I would consider implementing a sort of map/dictionary of URL paths to plugins. Then for each request received, do a lookup in the map and get the associated plugin and send it the request accordingly. If there is no entry in the map, then a redirect/proxy could be sent. For example if URL = <code>http://yourThriftServer/path/operation</code>, the operation or the path <strong><em>and</em></strong> operation would map to a plugin.</p> <p>An extra step would be to implement a sort of meta request, whereby a client could query what URL paths/operations are available in the server.</p> |

21,123,593 | 0 | How to get the value of a static object from within that object? <p>I’m trying to create a extern pointer to the value of a static object from within that static object. We’ll call this object Foo.</p> <p>Thus far, the only way I’ve gotten this to work is to create a Supervisor class that Foo inherits from that contains two static type variables. One, called superObject is the actual initialized object. The other, called superPointer, is a double pointer of the same type. Inside of the Foo object I declare an extern pointer named TheSupervisor and assign it a nullptr. Then, from within the Supervisor base class, I use the double pointer superPointer to change the value of TheSupervisor extern pointer to the address of the superObject. Wallah.</p> <p>The goal is here to create a globally accessible reference to this object. Trying my best to avoid singletons and keep things thread safe. I’m just wondering if there’s a better way?</p> <p>I'd post code, but I'd really have to clean it and change it around. I think the description is sufficient. Maybe even simpler, actually.</p> <p>EDIT: As it turns out, for static objects, I can't rely on when and in what order they are constructed. Using a one-phase process won't work for this. Instead, I have to keep relying on a two-phase process such as the one I outlined above. Marking Ilya Kobelevskiy's answer as correct as it demonstrates one way to do it, but again, it should come with a warning when used with static objects.</p> |

10,629,435 | 0 | Backbone.js rendering a reset collection with a single view <p>I'm trying to render a filtered collection from a single view using a select box using the reset property. First issue is that the select box and the rendered content must all appear in the same div in order to work. Is this normal? Second issue, is that instead showing the filtered results only, it appends the filtered collection to the end of the rendered content instead of replacing it.I know append in my ._each function won't work because it will only append the filtered items to the end of the entire collection. Here's my code sample below:</p> <pre><code>(function($) { var images = [ { tags: "Fun", date : "April 3, 2012", location : 'Home', caption : 'Having fun with my lady'}, { tags: "Chillin", date : "April 4, 2012", location : 'Home', caption : 'At the park with my lady'}, { tags: "Professional", date : "April 5, 2012", location : 'Home', caption : 'At the crib with my lady'}, { tags: "Education", date : "April 6, 2012", location : 'Home', caption : 'Having fun with my baby'}, { tags: "Home", date : "April 3, 2012", location : 'Home', caption : 'Having fun with my lady'}, { tags: "Professional", date : "April 4, 2012", location : 'Home', caption : 'At the park with my lady'}, { tags: "Fun", date : "April 5, 2012", location : 'Home', caption : 'At the crib with my lady'}, { tags: "Chillin", date : "April 6, 2012", location : 'Home', caption : 'Having fun with my baby'}, { tags: "Fun", date : "April 3, 2012", location : 'Home', caption : 'Having fun with my lady'}, { tags: "Education", date : "April 4, 2012", location : 'Home', caption : 'At the park with my lady'}, { tags: "Personal", date : "April 5, 2012", location : 'Home', caption : 'At the crib with my lady'}, { tags: "Personal", date : "April 6, 2012", location : 'Home', caption : 'Having a play date'} ]; var Item = Backbone.Model.extend({ defaults : { photo : 'http://placehold.it/200x250' } }); var Album = Backbone.Collection.extend({ model : Item }); var ItemView = Backbone.View.extend({ el : $('.content'), initialize : function() { this.collection = new Album(images); this.render(); $('#filter').append(this.createSelect()); this.on("change:filterType", this.filterByType); this.collection.on('reset', this.render, this); }, template : $('#img_container').text(), render : function() { var tmpl = _.template(this.template); _.each(this.collection.models, function (item) { this.$el.append(tmpl(item.toJSON())); },this); }, events: { "change #filter select" : "setFilter" }, getTypes: function () { return _.uniq(this.collection.pluck("tags"), false, function (tags) { return tags.toLowerCase(); }); }, createSelect: function () { var filter = this.$el.find("#filter"), select = $("<select/>", { html: "<option>All</option>" }); _.each(this.getTypes(), function (item) { var option = $("<option/>", { value: item.toLowerCase(), text: item.toLowerCase() }).appendTo(select); }); return select; }, setFilter: function (e) { this.filterType = e.currentTarget.value; this.trigger("change:filterType"); }, filterByType: function () { if (this.filterType === "all") { this.collection.reset(images); } else { this.collection.reset(images, { silent: true }); var filterType = this.filterType, filtered = _.filter(this.collection.models, function (item) { return item.get("tags").toLowerCase() === filterType; }); this.collection.reset(filtered); } } }); var i = new ItemView(); })(jQuery); </code></pre> |

That works perfectly fine with listening on $locationChangeStart and using its events preventDefault method. Unfortunately calling this method has the strange side effect of somehow "interrupting" the work of the function "handleNotification" which has the goal of notifying the user for 2 seconds that she or he has done something illegitimate.
