• When is it good to start using project management applications?

  - by Mr.Gando

  Hello, I was wondering, when is the right time or the correct project size to start using project management applications ( like Redmine or Trac ). I have a serious project, for now it's only me developing, but I use redmine to set my project versions, issues, and estimations. I think it's a good idea, because you never know when somebody else is going to join the team, and also allows me to organize myself effectively. I ask this question because I was Teaching Assistant at my university for one year in a row for a course, and I got questions about this very very often. While I'm a believer of the KISS principle, I think that learning to use this tools early is a win-win most of the time. I really believe that we can avoid this question to become argumentative, and that there's somewhat of a consensus about this issue, which I consider quite important in todays software development world. So, when is the right time ? what is the correct project/team size ?

• Caesar Cipher in Java (Spanish Characters)

  - by Rodolfo

  I've reading this question, and I was wondering if Is there any way to consider the whole range of characters? For example, "á", "é", "ö", "ñ", and not consider " " (the [Space])? (For example, my String is "Hello World", and the standard result is "Khoor#Zruog"; I want to erase that "#", so the result would be "KhoorZruog") I'm sure my answer is in this piece of code: if (c >= 32 && c <= 127) { // Change base to make life easier, and use an // int explicitly to avoid worrying... cast later int x = c - 32; x = (x + shift) % 96; chars[i] = (char) (x + 32); } But I've tried some things, and it didn't work.

• Rails - building an absolute url in a model's virtual attribute without url helper

  - by Nick

  I have a model that has paperclip attachments. The model might be used in multiple rails apps I need to return a full (non-relative) url to the attachment as part of a JSON API being consumed elsewhere. I'd like to abstract the paperclip aspect and have a simple virtual attribute like this: def thumbnail_url self.photo.url(:thumb) end This however only gives me the relative path. Since it's in the model I can't use the URL helper methods, right? What would be a good approach to prepending the application root url since I don't have helper support? I would like to avoid hardcoding something or adding code to the controller method that assembles my JSON. Thank you

• Does Displaytag stash the "media type" in a page or request attribute?

  - by Pointy

  When you enable "export" from Displaytag, the tag code gives you links with special magic parameters that the tag recognizes as indicators that the table contents should be exported (as CSV, Excel, whatever). Well I'm interested in detecting the media type so that (for example) I can exclude columns that make no sense in an export (embedded action buttons, for one thing, or checkboxes for row selection). I suppose I could write a table decorator and use that to stick the media type on the request, but it'd be nice to avoid that if the tag already does it. The documentation is not clear on the subject; I guess I can start digging through the source code too.

• Strange routing

  - by astropanic

  How I can setup my rails app to respond to such urls: http://mydomain.com/white-halogene-lamp http://mydomain.com/children-lamps http://mydomain.com/contact-form The first one should link to my products controller, and show my product with this name The second one should link to my categories controller, and show the category with this name The third one should link to my sites controller, and show the site with this title. All three models (product, category, site) have a method to_seo, giving the mentioned above urls (after the slash) I know it's not the restful way, but please don't disuss here, it is wrong approach or not, that's not the question. The question is how to accomplish this weird routing ? I know we have catch all routes, but how I can tell rails to use different controllers on different urls in the catch all route ? Or have You an better idea ? I would avoid redirects to other urls.

• Why will show() only work for fields that are hidden using inline css?

  - by Chris

  I am hiding an element using inline css, like so: <span class="hidden-nojs" style="display:none">Some text</span> Next I use jQuery to show the element, like so: $(".hidden-nojs").show(); This works great. As soon as I remove the inline css and put display:none on the external css stylesheet for the hidden-nojs class, it stops working. This is what I wrote in the external stylesheet: .hidden-nojs { display: none; } I'm assuming that the external stylesheet loads after the jQuery has already run? This is somewhat annoying as I would like to hide multiple elements with css and would like to avoid using inline css. Why will show() only work for fields that are hidden using inline css? How can I fix this problem?

• How to stop toggle event from being fired multiple times on mouseenter/mouseleave?

  - by Clean

  Hi, I'm using jQuery to toggle the visibility of a using the jQuery toggle method. The toggle is fired on the mouseenter and mouseleave event, thus creating the effect of the div to fold out on mouseenter and fold in on mouseleave. Problem is, if the user drags the mouse over the a few times and then leaves the , the div will toggle in and out several times. This can happen if the user accidentally moves around the mouse pointer in the are. Do anyone have any idea on how I can avoid this behavior? Thanx!

• How can I dynamically clear all controls in a user control?

  - by Michael

  Is it possible to dynamically (and generically) clear the state of all of a user control's child controls? (e.g., all of its TextBoxes, DropDrownLists, RadioButtons, DataGrids, Repeaters, etc -- basically anything that has ViewState) I'm trying to avoid doing something like this: foreach (Control c in myUserControl.Controls) { if (c is TextBox) { TextBox tb = (TextBox)c; tb.Text = ""; } else if (c is DropDownList) { DropDownList ddl = (DropDownList)c; ddl.SelectedIndex = -1; } else if (c is DataGrid) { DataGrid dg = (DataGrid)c; dg.Controls.Clear(); } // etc. } I'm looking for something like this: foreach (Control c in myUserControl.Controls) c.Clear(); ...but obviously that doesn't exist. Is there any easy way to accomplish this dynamically/generically?

• What's the easiest way to use OAuth with ActiveResource?

  - by Barry Hess

  I'm working with some old code and using ActiveResource for a very basic Twitter integration. I'd like to touch the app code as little as possible and just bring OAuth in while still using ActiveResource. Unfortunately I'm finding no easy way to do this. I did run into the oauth-active-resource gem, but it's not exactly documented and it appears to be designed for creating full-on API wrapper libraries. As you can imagine, I'd like to avoid creating a whole Twitter ActiveResource API wrapper for this one legacy change. Any success stories out there? In my instance, it might be quicker to just leave ActiveResource rather than get this working. I'm happy to be proven wrong!

• .NET Decimal = what in SQL?

  - by dmose

  What's the best data type in SQL to represent Decimal in .NET? We want to store decimal numbers with up to 9 decimal place precision and want to avoid rounding errors etc on the front end. Reading about data types, it appears using Decimal in .NET is the best option because you will not get rounding errors, although it is a bit slower than a Double. We want to carry this through down to the DB and want minimum conversion issues when moving data through the layers. Any suggestions?

• Longlasting Macport installation

  - by Werner

  Hi, I use Macports on Mac OSX to install some software. But there are somethings that I find very strange. For instance, yesterday I installed some app. and the it needed to get gcc43 and compile completely from source! It took a lot of time, although now everything works right. I understand that compilation of everything in the gentoo spirit is eomthing nice, but in the Mac case, not necessary. There are ony sole hardware variations, so it will be easier to get the binaries. I wonder if Macporst can be forced to get the binaries when available and therefore avoid these time consuming compilations. Thanks

• can I auto update my uitextview from the value of the row of my uipickerview without pressing any se

  - by Wesley

  So I have a uipicker view, that I have managed to load some data from my db into. I would like to update a textview, which is right above the pickerview, with each changing of the row. Is that possible? If I don't have to, I would like to avoid pushing a button in order to show the respective text. Can I make it so that the value in the text field changes with the value of the rowselected in the pickerview, in real time? Any thoughts or code snippets would be appreciated. Thanks!

• HttpWebRequest timeout in Windows service

  - by googler1

  I am getting a timeout error while starting my Windows service. I am tring to download an XML file from a remote system which causes a timeout during the service OnStart. This is the method I am calling from OnStart: public static StreamReader GetResponseStream() { try { EventLog.WriteEntry("Epo-Service_Retriver", "Trying ...", EventLogEntryType.Information); CookieContainer CC = new CookieContainer(); HttpWebRequest request = (HttpWebRequest)WebRequest.Create( Utils.GetWeeklyPublishedURL()); request.Proxy = null; request.UseDefaultCredentials = true; request.KeepAlive = true; //THIS DOES THE TRICK request.ProtocolVersion = HttpVersion.Version10; // THIS DOES THE TRICK request.CookieContainer = CC; WebResponse response = request.GetResponse(); StreamReader reader = new StreamReader(response.GetResponseStream()); EventLog.WriteEntry("Epo-Service_Retriver", "Connected to Internet...", EventLogEntryType.SuccessAudit); return reader; } } Is there any possibility to avoid this timeout?

• AdMob Android integration - what permissions to ask for?

  - by AngryHacker

  In the various videos on the AdMob integration, I've seen that only permission to access the internet is asked for: <uses-permission android:name="android.permission.INTERNET" /> Not that I am an expert in advertising, but wouldn't AdMob need the user's geographic location as well, so that they can serve location specific ads? Or avoid serving certain ads based on a location, like maybe not offering me a Big Mac if I am in India or not adverting a ham sandwich if I am in an Arab country? If AdMob needs those permissions, how do I ask for them?

• In Prism (CAL), how can I RegisterPresenterWithRegion instead of RegisterViewWithRegion

  - by Edward Tanguay

  I have a module in a Prism application and in its initialize method I want to register a presenter instead of a view with a region, i.e. I want to do this: PSEUDO-CODE: regionManager.RegisterPresenterWithRegion( "MainRegion", typeof(Presenters.EditCustomerPresenter)); instead of loading a view like this: regionManager.RegisterViewWithRegion( "MainRegion", typeof(Views.EditCustomerView)); The presenter would of course bring along its own view and ultimately register this view in the region, but it would allow me to bind the presenter to the view in the presenter's constructor instead of binding the two together in XAML (which is more of a decoupled MVVM pattern which I want to avoid here). How can I add a Presenter to a Region instead of a view? namespace Client.Modules.CustomerModule { [Module(ModuleName = "CustomerModule")] public class CustomerModule : IModule { private readonly IRegionManager regionManager; public CustomerModule(IRegionManager regionManager) { this.regionManager = regionManager; } public void Initialize() { regionManager.RegisterViewWithRegion("MainRegion", typeof(Views.EditCustomerView)); } } }

• htaccess/htpasswd in hierarchical folder structure

  - by chessweb

  I have a folder (folder_1) that is protected by htaccess/htpasswd files. Inside that folder is another folder (folder_2) that is protected by another couple of htaccess/htpasswd files. When a php-script in folder_1 or folder_2 is called, the user has to authenticate herself using the correct username and password as specified in the respective htaccess/htpasswd files. This works as intended. However, as soon as the php-script in folder_2 tries to refer to another script or a css-file that is located in folder_1, the user must enter username and password for folder_1 as well. Is there a way to avoid this that does not involve copying scripts and css-files from folder_1 to folder_2? Regards, Ralf

• iPhone SDK:How do you play video inside a view? Rather than fullscreen.

  - by Jessica

  Hi, I am trying to play video inside a UIView, so my first step was to add a class for that view and start playing a movie in it using this code: - (IBAction)movie:(id)sender{ NSBundle *bundle = [NSBundle mainBundle]; NSString *moviePath = [bundle pathForResource:@"Movie" ofType:@"m4v"]; NSURL *movieURL = [[NSURL fileURLWithPath:moviePath] retain]; MPMoviePlayerController *theMovie = [[MPMoviePlayerController alloc] initWithContentURL:movieURL]; theMovie.scalingMode = MPMovieScalingModeAspectFill; [theMovie play]; } But this just crashes the app when using this method inside it's own class, but is fine elsewhere. Does anyone know how to play video inside a view? and avoid it being full screen?

• Guidelines of when to use locking

  - by miguel

  I would like to know if there are any guidelineswhich a developer should follow as to when (and where) to place locks. For instance: I understand that code such as this should be locked, to avoid the possibility of another thread changing the value of SomeHeapValue unexpectedly. class Foo { public SomeHeapObject myObject; public void DoSummat(object inputValue_) { myObject.SomeHeapValue = inputValue_; } } My question is, however, how deep does one go with the locking? For instance, if we have this code: class Foo { public SomeHeapObject myObject; public void DoSummat(object inputValue_) { myObject.SomeHeapValue = GetSomeHeapValue(); } } Should we lock in the DoSummat(...) method, or should we lock in the GetSomeHeapValue() method? Are there any guidelines that you all keep in mind when strcturing multi-threaded code?

• Programmatically adding a site to the Allowed Sites of the IE Pop-up Blocker (VB.NET)

  - by GlueR

  A few more details. I need to programmatically (Winforms, VB.NET) check if a site is in the Allowed Sites list of the IE Pop-Up Blocker (IE 7 and 8 and Windows XP, Vista and 7) and if not, add it. The application is fully trusted and I don't want to disable the Pop-Up blocker entirely. To clarify some things, this is for a web-automation application with several users across 3 countries. I want to avoid receiving tons of emails and explaining each time how to add the website to the Allowed Sites manually. Also, some of the users have Google Toolbar installed, which also has a Popup Blocker creating trouble to my app. Can this also be done programmatically?

• Django database caching

  - by hekevintran

  I have a Django form that uses an integer field to lookup a model object by its primary key. The form has a save() method that uses the model object referred to by the integer field. The model's manager's get() method is called twice, once in the clean method and once in the save() method: class MyForm(forms.Form): id_a = fields.IntegerField() def clean_id_a(user_id): id_a = self.cleaned_data['id_a'] try: # here is the first call to get MyModel.objects.get(id=id_a) except User.DoesNotExist: raise ValidationError('Object does not exist') def save(self): id_a = self.cleaned_data['id_a'] # here is the second call to get my_model_object = MyModel.objects.get(id=id_a) # do other stuff I wasn't sure whether this hits the database two times or one time so I returned the object itself in the clean method so that I could avoid a second get() call. Does calling get() hit the database two times? Or is the object cached in the thread? class MyForm(forms.Form): id_a = fields.IntegerField() def clean_id_a(user_id): id_a = self.cleaned_data['id_a'] try: # here is my workaround return MyModel.objects.get(id=id_a) except User.DoesNotExist: raise ValidationError('Object does not exist') def save(self): # looking up the cleaned value returns the model object my_model_object = self.cleaned_data['id_a'] # do other stuff

• Range partition skip check

  - by user289429

  We have large amount of data partitioned on year value using range partition in oracle. We have used range partition but each partition contains data only for one year. When we write a query targeting a specific year, oracle fetches the information from that partition but still checks if the year is what we have specified. Since this year column is not part of the index it fetches the year from table and compares it. We have seen that any time the query goes to fetch table data it is getting too slow. Can we somehow avoid oracle comparing the year values since we for sure know that the partition contains information for only one year.

• UISearchDisplayController's full-screen background intercepts touch events in iOS 7

  - by tba

  I have a UITableview that doesn't take up the whole screen (screenshot). Everything worked fine in iOS 6. But in iOS 7, when the user searches, the search result table takes up the whole view (screenshot). To fix this, I tried setting the frame manually as described in this answer. The appearance is now correct (screenshot), but now the "<" button in the top left doesn't receive tap events when the search results table is displayed. It seems the searchResultsTableView is adding a full-screen background view that is intercepting touch events. To prove this, I added this code to didShowSearchResultsTableView: controller.searchResultsTableView.superview.backgroundColor = [UIColor blueColor];` This screenshot confirms my hypothesis. How can I fix this to allow the "<" button to receive tap events? I want to avoid modifying controller.searchResultsTableView.superview so that my change doesn't break in future versions of iOS. And what change in iOS 7 caused this behavior to start happening?
